TECHNICAL FIELD

The present invention relates to a technical field of golf bags and accessories, particularly to a tiltable standing golf bag base with a braking function and a golf bag with a braking function.

BACKGROUND

With the continuous improvement of people's living standards, the demand for quality of life has also increased. As a result, the number of people engaging in leisure, travel, and sports during their days off has grown rapidly. Among outdoor recreational activities, golf has become one of the most popular sports. Once considered an aristocratic pastime, golf has gradually become a widely accessible sport, gaining popularity among more and more people.

Common golf bags can be classified into two types based on their standing method: one is upright, and the other is tilted. The advantage of a tilted golf bag is that it stands diagonally on the ground with the support of its legs, making it convenient for users to take and place golf clubs during the game. However, tilted golf bags do not equip with wheels. This is because the process of a tilted golf bag tilting to stand involves pressing the entire bag downwards at an angle to deploy the support legs and achieve the tilted standing position. If wheels were installed on the base, the golf bag would tend to slide to one side before the support legs could be deployed. This would not only prevent the legs from extending but also make the golf bag prone to falling over.

Due to the above reasons, tilted golf bags do not have a wheel structure, which also makes it inconvenient for users to carry the bag, as it can only be carried by holding it suspended.

The first engaging parts are configured to correspond with the second engaging part, and when the movable bracket pivots upward, the first engaging parts gradually approach the second engaging part, causing the first engaging parts to engage with the second engaging part.

In a further embodiment, the lower end of the linkage mechanism is connected to the movable bracket.

In a further embodiment, the stop portion is provided with a through connection hole, through which the lower end of the linkage mechanism passes to connect with the movable bracket.

In another embodiment, the linkage mechanism is a U-shaped steel wire.

In another embodiment, the stop portion is equipped with a wheel placement groove, and the wheel placement groove is positioned to correspond with the wheel's location. When the movable bracket pivots to its highest position, the wheel is positioned inside the wheel placement groove.

In a further embodiment, the first engaging parts are evenly distributed around the rolling surface of the wheel. The second engaging part is positioned on the fixed base, located within the pivoting path of the movable bracket.

When the golf bag needs to be positioned at an angle with the support legs extended, a user presses downward diagonally on the side of the bag where the support legs are located. The action causes the movable bracket to pivot upward due to the reactive force. During the pivoting motion, the first engaging parts on the rolling surface of the wheel gradually approach and eventually engage with the second engaging part located on the fixed base. The engagement locks the wheel's movement, facilitating the user in deploying the support legs and allowing the golf bag to stand at an angle on the ground.

When the golf bag's support legs need to be retracted, the user can simply lift the bag straight upward. The action causes the movable bracket to pivot downward due to the influence of the linkage mechanism and gravity. As the bracket pivots downward, the first engaging parts gradually moves away from the second engaging part, disengaging their interlock and restoring the wheel's ability to move freely.

In a further embodiment, the first engaging parts are evenly distributed around the inner surface of the wheel, while the second engaging part is positioned on the movable bracket.

In a further embodiment, the fixed base is equipped with a sloped fixing block. The sloped fixing block has at least one tip pointed towards the ground and extends upwards from the tip with at least one sloped surface.

In a further embodiment, the first engaging parts are engaging holes, and the second engaging part is an engaging shaft. The inner diameter of the engaging hole is slightly larger than the outer diameter of the engaging shaft, and the engaging hole is arranged to cooperate with the engaging shaft.

In a further embodiment, the engaging shaft is further provided with a sliding device. One end of the engaging shaft, which is near the engaging hole, is the engaging end, while the opposite end, which is away from the engaging hole, is the sliding end. The sliding device includes a pulley and a spring. The pulley is arranged at the sliding end, and the spring is sleeved around the engaging shaft and positioned between the engaging end and the sliding end.

In a further embodiment, the fixed base is further provided with a sloped fixing block. The sloped fixing block has at least one tip pointed towards the ground and extends upwards from the tip with at least one sloped surface. The first engaging part is arranged evenly around the inner surface of the wheel, while the second engaging part is arranged on the movable bracket. The first engaging part are engaging holes, and the second engaging part is an engaging shaft. The inner diameter of the engaging hole is slightly larger than the outer diameter of the engaging shaft, and the engaging hole is arranged to cooperate with the engaging shaft. The engaging shaft is further provided with a sliding device. One end of the engaging shaft, which is near the engaging hole, is the engaging end, while the opposite end, which is away from the engaging hole, is the sliding end. The sliding device includes a pulley and a spring. The pulley is arranged at the sliding end, and the spring is sleeved around the engaging shaft and positioned between the engaging end and the sliding end. The sloped fixing block is positioned along the pivoting path of the sliding end of the engaging shaft, and when the movable bracket swings to its highest position, the pulley abuts against the tilted surface of the sloped fixing block.

When the golf bag needs to stand at a tilted angle with the support legs extended, the user presses downward on one side of the golf bag's support leg. In response, the movable bracket pivots upward. During the pivoting process, the pulley is driven to slide along the tilted surface of the sloped fixing block. The sliding of the pulley causes the engaging shaft to insert into the engaging hole on the inner surface of the wheel, locking the wheel's movement and making it easier for the user to extend the support legs, allowing the golf bag to stand at a tilted angle on the ground.

When the golf bag needs to retract the support legs, the user can simply lift the golf bag directly upward. Under the influence of the linkage mechanism and gravity, the movable bracket pivots downward. Meanwhile, the engaging shaft, under the action of the spring, causes the pulley to move along the tilted surface of the sloped fixing block, driving the engaging shaft to exit the engaging hole, and restoring the wheel's movement state.

The golf bag with a braking function comprises a bag body, a head frame, and a base. The head frame is arranged at the top of the bag body, and the base is arranged at the bottom of the bag body. A pair of support legs extending downward along the bag body are provided on one side of the head frame. The support legs are driven to open and close by a linkage mechanism, the upper end of the linkage mechanism is connected to the support legs. The base is equipped with wheels, which are connected to a rotating shaft. The base includes a fixed seat and a movable bracket. The proximal end of the movable bracket is hinged to the fixed seat, and the distal side of the movable bracket is near the support legs, with wheels arranged on the distal side. The distal side of the movable bracket can pivot up and down around the hinge point of the fixed seat. The fixed seat includes a horizontal bottom surface and a stop portion, with the horizontal bottom surface parallel to the ground. The stop portion is positioned higher than the horizontal bottom surface and is located within the pivoting path of the movable bracket. The pivoting path of the movable bracket in the upward direction is limited by the stop portion. The base is also equipped with a braking component, which includes several first engaging parts arranged on the rotating shaft and a second engaging part arranged on the base. The first engaging parts are configured to correspond with the second engaging part, and when the movable bracket pivots upward, the first engaging parts gradually approach the second engaging part, causing the first engaging part and the second engaging part to engage.

In a further embodiment, the lower end of the linkage member is connected to the movable bracket.

In a further embodiment, the stop portion is also provided with a through connection hole, and the linkage member passes through the through connection hole and connects with the movable bracket.

In a further embodiment, the linkage mechanism is a U-shaped steel wire.

In a further embodiment, the stop portion is provided with a wheel placement groove, and the wheel placement groove is arranged to match the position of the wheel. When the movable bracket pivots to its highest position, the wheel is positioned within the wheel placement groove.

In a further embodiment, the second engaging part is provided on the fixed seat, and the second engaging part is located within the pivoting path of the movable bracket.

In a further embodiment, the first engaging parts are engaging holes, the second engaging part is an engaging shaft, the inner diameter of the engaging hole is slightly larger than the outer diameter of the engaging shaft, and the engaging hole is arranged to cooperate with the engaging shaft.

When the golf bag needs to stand diagonally with the support legs extended, the user presses down on one side of the golf bag's support leg. The movable bracket pivots upward under the reaction force. During the pivoting process, the first engaging part on the rotating shaft gradually moves closer to and eventually locks into the second engaging part located on the fixed base, thereby locking the movement of the wheel, making it easier for the user to extend the support legs and place the golf bag at a slant on the ground.

When the golf bag needs to retract the support legs, the user can directly lift the golf bag upwards. The movable bracket pivots downward under the influence of the linkage and gravity, while the first engagement part gradually moves away from the second engagement part, disengaging from the interlocking connection and restoring the movement of the wheel.

The golf bag with a braking function includes a bag body, a head frame, and a base. The head frame is located at the top of the bag body, and the base is located at the bottom of the bag body. A pair of support legs extend downward along one side of the head frame. The support legs are driven by a linkage mechanism to open and close, with the upper end of the linkage connected to the support legs. The base is equipped with wheels, and the wheels are connected to a rotating shaft. The base includes a fixed base and a movable bracket, with the near side of the movable bracket hinged to the fixed base. The distal end of the movable bracket, which is close to the support legs, is also equipped with wheels. The distal end of the movable bracket can pivot up and down around the hinge point with the fixed base. The fixed base includes a horizontal bottom surface and a stop portion. The horizontal bottom surface is parallel to the ground, and the stop portion is positioned higher than the horizontal bottom surface and is located within the pivot path of the movable bracket. The pivoting path of the movable bracket in the upward direction is limited by the stop portion. The wheels are unidirectional and can only move the golf bag toward the side of the support legs.

In a further embodiment, the lower end of the linkage mechanism is connected to the movable bracket.

In a further embodiment, the stop portion is also provided with a through connection hole, and the linkage mechanism passes through the through connection hole to connect with the movable bracket.

In a further embodiment, the linkage mechanism is a U-shaped steel wire.

In a further embodiment, the stop portion is provided with a wheel placement groove, which is positioned to match the wheel's location, and when the movable bracket pivots to its highest position, the wheel is located within the wheel placement groove.

When using a structure with a unidirectional wheel, the golf bag is directly pressed downward at an angle. Since the unidirectional wheel only rolls towards the side of the support legs, the wheel will not roll in the opposite direction when the support legs are deployed. It maintains the overall stability of the golf bag's structure and prevents the golf bag from tipping over due to the rolling of the wheel.

The present invention provides a wheel structure for a golf bag with support legs while maintaining overall stability by conditionally restricting the wheel from rolling to the opposite side when the support legs are deployed. This design not only allows the golf bag to stand diagonally for easy retrieval and storage of golf clubs during play but also facilitates the user in dragging the bag using the wheels when carrying the golf bag in a diagonal position, greatly enhancing the portability of the golf bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following will further explain the concepts, specific structure, and technical effects of the present invention in combination with the accompanying drawings, to fully understand the objectives, features, and effects of the invention.

It should be noted that in the description of the present invention, terms such as “upper”, “lower”, “left”, “right”, “tip”, “wide side”, and other directional or positional terms are based on the directions or positional relationships shown in the drawings. These are for descriptive convenience only and do not indicate or suggest that the device or components must have a specific orientation, structure, or operation in a particular direction. Therefore, they should not be interpreted as limitations of the present invention.

The first embodiment of the present invention, as shown in FIGS. 1-2, is a golf bag with a brake function, which includes a bag body 2, a head frame 1, and a base 3. The head frame 1 is fixedly connected to the top of the bag body 2, and the base 3 is fixedly connected to the bottom of the bag body 2. A pair of support legs 11 extend downward along the bag body on the right side of the head frame 1. The top of the support legs 11 is connected to the top end of a U-shaped steel wire 12, which can drive the support legs 11 to open and close. The base 3 includes a fixed base 31 and a movable bracket 32. The proximal end of the movable bracket 32 is hinged to the fixed base 31, and the distal end of the movable bracket 32 is equipped with a wheel 4. The movable bracket 32 can pivot up and down around the hinge point with the fixed base 31. The base 3 includes the fixed base 31 and the movable bracket 32. The left half of the fixed base 31 that touches the ground and forms a horizontal bottom surface 312, while the right half of the fixed base 31 extends upward along the right side of the horizontal bottom surface 312 and is provided with a stop portion 311, which is located above the wheel 4.

As shown in FIGS. 3 to 8, the fixed base 31 near the stop part 311 is provided with a through connection hole 313. The lower end of the U-shaped steel wire 12 passes through the through connection hole 313 and connects to the movable bracket 32. The distal ends of the movable bracket 32 are each connected to two wheels 4. At the position corresponding to the wheels 4 on the stop portion 311, two wheels placement grooves 3111 and a triangular-shaped sloped fixing block 3112 are respectively provided. The wheel placement grooves 3111 are positioned at the location of the two wheels 4 after the movable bracket 32 pivots upward, while the sloped fixing block 3112 is set with its pointed end facing downward in the middle of the two wheels placement grooves 3111. The sloped fixing block 3112 extends upward from its pointed end with two tilted surfaces.

As shown in FIGS. 9-10, two wheels 4 are connected to the distal ends of the movable bracket 32. On the inner surface of the two wheels 4, near the direction of the movable bracket 32, several first engagement holes 41 are annularly arranged. Additionally, two first engagement shafts 54 and two sets of sliding components 5 are laterally arranged at the positions of the movable bracket 32 close to the two wheels 4. The sliding component 5 includes a pulley 53, a spring 52, and a spring washer 51. The first engagement shaft 54 has a connection end near the corresponding wheel 4 and a sliding end on the other side. The pulley 53 is set at the sliding end, while the spring washer 51 is positioned near the connection end and is fixedly connected to the movable bracket 32. The spring 52 is sleeved around the outer side of the first engagement shaft 51 and is placed between the spring washer 52 and the pulley 53. The inner diameter of the first engagement hole 41 is slightly larger than the outer diameter of the first engagement shaft 54, allowing the first engagement shaft 54 to be inserted into the first engagement hole 41 when displacement occurs.

As shown in FIGS. 1-10, when the movable bracket 32 pivots upward under the user's control, the pulley 53 gradually approaches and abuts the tilted surface of the sloped fixing block 3112. During the further pivoting process of the movable bracket 32, the pulley 53 moves from the tip of the sloped fixing block 3112 to the wide side, driving the first engaging shaft 54 to move toward the direction of the wheel 4, ultimately causing the first engaging shaft 54 to engage with the first engaging hole 41.

During application of embodiment 1, when the golf bag needs to stand diagonally with the support legs 11 extended, the user presses downward and diagonally on one side of the golf bag's support legs 11. Under the reactive force, the movable bracket 32 pivots upward. During the pivoting process, the pulley 53 slides along the tilted surface of the sloped fixing block 3112, and the sliding of the pulley 53 drives the first engaging shaft 54 into the first engaging hole 41 on the inner surface of the wheel 4, locking the movement of the wheel 4, which facilitates the user to extend the support legs 11 and allow the golf bag to stand diagonally on the ground.

When the golf bag needs to retract the support legs 11, the user can directly lift the golf bag upward. Under the influence of the U-shaped steel wire 12 and gravity, the movable bracket 32 pivots downward. At the same time, the first engaging shaft 54, under the action of the spring 52, causes the pulley 53 to move closely along the tilted surface of the tilted fixed block 3112, driving the first engaging shaft 54 to exit from the first engaging hole 41, thereby restoring the movement of the wheel 4.

In the second embodiment of the present invention, as shown in FIGS. 11-12, the base 3 includes a fixed seat 31 and a movable bracket 32. The proximal end of the movable bracket 32 is hinged to the fixed seat 31, and the distal end of the movable bracket 32 is equipped with a wheel 4. The movable bracket 32 can pivot up and down around the hinge point with the fixed seat 31. The base 3 includes the fixed seat 31 and the movable bracket 32. The left half of the fixed seat 31 that contacts the ground and forms a horizontal bottom surface 312, and the right half of the fixed seat 31 extends upward from the horizontal bottom surface 312 to form a stop portion 311, which is positioned above the wheel 4. A through connecting hole 313 is located near the stop portion 311 of the fixed seat 31. The lower end of the U-shaped steel wire 12 passes through the through connection hole 313 and connects to the movable bracket 32. The movable bracket 32 is connected to two wheels 4, and two wheels placement grooves 3111 are provided at the positions corresponding to the wheels 4 relative to the stop portion 311. Each of the wheel placement grooves 3111 is further provided with a second engaging shaft 55 extending downward. Several second engaging holes 42 are evenly arranged on the rolling surface of the wheels 4. During the upward pivoting motion of the movable bracket 32, the second engaging holes 42 on the rolling surface of the wheels 4 gradually approach the second engaging shaft 55.

During application of embodiment 2, when the golf bag needs to stand diagonally with the support legs 11 extended, the user presses down on one side of the support legs 11 of the golf bag. Under the reaction force, the movable bracket 32 pivots upward. During the pivoting process, the second engaging holes 42 on the rolling surface of the wheel 4 gradually approach the second engaging shaft 55 located in the wheel placement groove 3111, and eventually, the two are locked together, securing the movement of the wheel 4. This makes it easier for the user to extend the support legs 11, allowing the golf bag to stand diagonally on the ground.

When the golf bag needs to retract the support leg 11, the user can directly lift the golf bag upward. Under the influence of the U-shaped steel wire and gravity, the movable bracket 32 pivots downward. At the same time, the second engaging shaft 55, located in the wheel placement groove 3111, gradually disengages from the second engaging hole 42 on the rolling surface of the wheel 4, restoring the movement state of the wheel 4.

Third embodiment of the present invention, as shown in FIGS. 13-15, the base 3 includes a fixed base 31 and a movable bracket 32. The proximal end of the movable bracket 32 is hinged to the fixed base 31, and the distal end of the movable bracket 32 is equipped with a wheel 4. The movable bracket 32 can pivot up and down around the hinge point with the fixed base 31. The base 3 includes the fixed base 31 and the movable bracket 32. The fixed base 31 has a horizontal bottom surface 312 parallel to the ground, and the fixed base 31 extends upward along this horizontal bottom surface 312 to provide a stop portion 311, which is located above the wheel 4. The proximal end of the movable bracket 32 are connected to two wheels 4, and in the position corresponding to the stop portion 311 and the wheels 4, two wheel placement grooves 3111 are arranged. In the middle of the stop portion 311, there is a third engaging shaft 56 extending downward. Inside the movable bracket 32, there is also a rotating shaft 44, the two ends of which are connected to the two wheels 4. In the middle of the rotating shaft 44, several third engaging holes 43 are arranged around the shaft. In the positions corresponding to the third engaging holes 43 on the movable bracket 32, there is also a through hole 57 facing the direction of the third engaging shaft 56.

In the application of the third embodiment, when the golf bag needs to stand at an angle with the support legs 11 extended, the user presses down on one side of the golf bag's support legs 11. The movable bracket 32 pivots upward under the reaction force. During the pivoting process, the third engaging hole 43 in the middle of the rotating shaft 44 gradually moves toward the third engaging shaft 56 located in the center of the stop portion 311. Eventually, the third engaging shaft 56 passes through the through hole 57 and locks into the third engaging hole 43, thereby locking the movement of the rotating shaft 44 and further securing the movement of the wheel 4. This facilitates the user in extending the support legs 11, allowing the golf bag to stand at an angle on the ground.

When the golf bag needs to retract the support legs 11, the user can directly lift the golf bag upward. The movable bracket 32 pivots downward under the influence of the U-shaped steel wire 12 and gravity. At the same time, the third engaging shaft 56 located in the middle of the stop portion 311 gradually disengages from the third engaging hole 43 in the middle of the rotating shaft 44, restoring the movement state of the wheel 4.

The fourth embodiment of the present invention, as shown in FIG. 16, includes a base 3 comprising a fixed seat 31 and a movable bracket 32. The proximal end of movable bracket 32 is hinged to the fixed seat 31, and the distal end of the movable bracket 32 is equipped with a unidirectional wheel 6. The movable bracket 32 can pivot up and down around the hinge point with the fixed seat 31, and the unidirectional wheel 6 can only roll to the right as shown in the figure. The base 3 includes the fixed seat 31 and the movable bracket 32, with the horizontal bottom surface 312 of the fixed seat 31 parallel to the ground. The fixed seat 31 extends upward from the horizontal bottom surface 312 with a stop portion 311, which is located above the unidirectional wheel 6.

In the application of the fourth embodiment, when the golf bag is pressed diagonally downward, the unidirectional wheel 6 only rolls toward the side of the support leg 11. As a result, when the support leg 11 is extended, the unidirectional wheel 6 will not roll in the opposite direction, maintaining the overall stability of the golf bag structure.

It should be noted that the above specific embodiments are only preferred embodiments of the present invention and the technical principles applied. Within the technical scope disclosed in this invention, any changes or substitutions that would be obvious to a person skilled in the art are also covered by the protection scope of the present invention. For example, the position of the engagement axis is not uniquely limited to the movable bracket; the engagement axis can also be placed on the fixed base. Furthermore, the engagement method is not limited to inserting into the wheel; the engagement axis can also be inserted and engaged with the rotating shaft or the extended part of the rotating shaft. Additionally, the engagement axis can not only engage with a hole-shaped structure but also with a groove-shaped structure.
