Description

RELATED APPLICATIONS

This application claims priority to Chinese patent application number 202410109549.8, filed on Jan. 25, 2024. Chinese patent application number 202410109549.8 is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to camping equipment and in particular to a quick disassembly and assembly structure for a frame rod and a canopy fabric of a canopy frame with eaves.

BACKGROUND OF THE DISCLOSURE

Existing canopies with eaves, such as those disclosed in CN203285138U, CN207485092U, CN207469881U, CN206987440U, CN105781225A, CN205012752U, CN103850518A, CN203547226U, CN103590650A, and CN203420512U, each include a frame rod comprising a plurality of eave rods with outer ends arranged in a suspended manner. During use, referring to FIG. 1, a canopy fabric 20′ covers the frame rod of the canopy with eaves. The canopy fabric 20′ has a plurality of corners corresponding to the plurality of eave rods 101′ and a plurality of triangular fabric pieces 22′. Two edges of each of the plurality of triangular fabric pieces 22′ are sewn to two edges of a corresponding one of the plurality of corners, forming a plurality of sleeves 23′ each having an opening facing inward. To enhance strength, an inside of each of the plurality of sleeves 23′ is disposed with a reinforcing fabric sleeve. During assembly, the frame rod is first unfolded, and then the outer ends of the plurality of eave rods 101′ are inserted into the reinforcing fabric sleeves of the plurality of sleeves 23′ of the canopy. However, this design has the following drawbacks: firstly, during the insertion process, the outer ends of the plurality of eave rods 101′ are often mistakenly placed outside the reinforcing fabric sleeves (although still within the plurality of sleeves 23′), which can easily puncture the canopy fabric 20′; secondly, the insertion connection is prone to detachment, particularly during disassembly after assembly, and the outer ends of the plurality of eave rods 101′ and the reinforcing fabric sleeves may naturally fall off; thirdly, the frame rod must be unfolded first before inserting the outer ends of the plurality of eave rods 101′ into the reinforcing fabric sleeves, making it impossible to insert the outer ends of the plurality of eave rods 101′ into the reinforcing fabric sleeves beforehand.

In a structure disclosed in CN203420512U, the outer ends of plurality of eave rods 101′ are equipped with plugs, and the plugs are located outside lower supporting tubes. Each of the plugs comprises a fixed sleeve that can secure the outer end of a corresponding one of the plurality of eave rods 101′ and two outer eave seats symmetrically disposed on two sides of the fixed sleeve, and an included angle between the two outer eave seats preferably is 90 degrees. The plugs serve two purposes: the plugs inhibit the plurality of eave rods 101′ from fully retracting into the lower supporting tubes and facilitate a connection of the canopy fabric 20′, reducing a risk of puncturing the canopy fabric 20′. During use, the plugs are also inserted into the reinforcing fabric sleeves of the canopy. Although the plugs reduce the likelihood of puncturing, the following shortcomings are still shown: firstly, during the insertion process, the outer ends of the plurality of eave rods 101′ are often mistakenly placed outside the reinforcing fabric sleeves (although still within the plurality of sleeves 23′), which can easily puncture the canopy fabric 20′; secondly, the insertion connection are prone to detachment, particularly during disassembly after assembly, the outer ends of the plurality of eave rods 101′ and the reinforcing fabric sleeves may naturally fall off; thirdly, the frame rod must be unfolded first before inserting the outer ends of the plurality of eave rods 101′ into the reinforcing fabric sleeves, making it impossible to insert the outer ends of the plurality of eave rods 101′ into the reinforcing fabric sleeves beforehand.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

A quick disassembly and assembly structure for a frame rod 10 and a canopy fabric 20 of a canopy frame with eaves is shown in FIGS. 2 to 10. The frame rod 10 of the canopy frame with the eaves comprises a plurality of eave rods 101, and each of the plurality of eave rods 101 has an outer end that is suspended. The canopy fabric 20 is draped over the frame rod 10, and a plurality of connecting members 30 are connected to the canopy fabric 20. The plurality of connecting members 30 and the canopy fabric 20 are connected together. The plurality of connecting members 30 can be detachably sleeved outside the outer ends of the plurality of eave rods 101 to enable the frame rod 10 and the canopy fabric 20 to be connected together. Since the plurality of connecting members 30 can be detachably connected to the outer ends of the plurality of eave rods 101, the plurality of connecting members 30 can be sleeved on the outer ends of the plurality of eave rods 101 to achieve a connection during use. Therefore, firstly, since the plurality of connecting members 30 and the canopy fabric 20 are connected together, the plurality of eave rods 101 and the plurality of connecting members 30 are convenient to be sleeved together, so as to avoid the plurality of eave rods 101 piercing the canopy fabric 20 and extend a service life of the canopy fabric 20. Secondly, since the plurality of connecting members 30 and the canopy fabric 20 are connected together and the plurality of eave rods 101 and the plurality of connecting members 30 are sleeved together, a connection between the plurality of connecting members 30 and the plurality of eave rods 101 is firm and stable. Not only will the connection between the plurality of connecting members 30 and the plurality of eave rods 101 not be separated when the frame rod 10 is folded and not only can the canopy fabric 20 be folded directly after unfolding (there is no need to worry about the plurality of connecting members 30 and the plurality of eave rods 101 being separated after folding), but also an unfolding method of connecting the plurality of connecting members 30 and the plurality of eave rods 101 first and then unfolding the frame rod 10 can be realized, providing a new unfolding or folding method, which is fast, accurate, convenient, and quick to unfold or fold.

Each of the plurality of connecting members 30 has a fixed portion 31 and a connecting portion 32 which are fixedly connected to each other. Two ends of the fixed portion 31 extend out of the connecting portion 32. The fixed portion 31 comprises a through hole 311, and the through hole 311 is a long-hole structure. The long-hole structure is perpendicular to a corresponding one of the plurality of connecting members 30. A connecting belt 40 is also provided to pass through the through hole 311 and is connected to the canopy fabric 20. Firstly, it is convenient to install and remove the plurality of connecting members 30 and the plurality of eave rods 101. Secondly, the two ends of the fixed portion 31 extend out of the connecting portion 32, which can increase a width of the connecting belt 40, increase connecting strength between the connecting belt 40 and the connecting portion 32, and increase connecting strength between the connecting belt 40 and the canopy fabric 20.

In this embodiment, the connecting belt 40 can be webbing, and the two ends of the connecting belt 40 can be sewn, welded, or fused to a bottom surface of one of corners 201 of the canopy fabric 20, which is easy to process.

In this embodiment, the connecting portion 32 comprises a cap-shaped sleeve 321, and the cap-shaped sleeve 321 has an opening. The opening of the cap-shaped sleeve 321 can be detachably sleeved outside the outer end of a corresponding one of the plurality of eave rods 101, so as to facilitate assembly and disassembly of the plurality of connecting members 30 and the plurality of eave rods 101. In order to facilitate a sleeve connection and improve connection firmness between the cap-shaped sleeve 321 and the corresponding one of the plurality of eave rods 101, at least two guiding strips 322 arranged at intervals in a circumferential direction of the cap-shaped sleeve 321 protrude from an inner wall of the opening of the cap-shaped sleeve 321, and a front end of each of the at least two guiding strips 322 comprises a guiding inclined surface.

In this embodiment, the frame rod 10 comprises a canopy frame and a plurality of side eave frames.

The canopy frame comprises at least three columns 102 and an upper canopy frame connected to the at least three columns 102. A top end of each of the at least three columns 102 is fixedly disposed with an upper connecting seat 103, and the upper canopy frame is connected to the upper connecting seat 103. Each of the at least three columns 102 is slidably disposed with a sliding seat 104, and a folding frame 105 is connected to the upper connecting seats 103 and the sliding seats 104 of each pair of adjacent columns of the at least three columns 102. The folding frame 105 comprises a plurality of scissor-shaped connecting rod groups 1051 pivotally connected in series. The folding frame 105 has four ends, which are respectively rotatably connected to the upper connecting seats 103 and the sliding seats 104 of each pair of the adjacent columns of the at least three columns 102. The upper canopy frame comprises a first middle seat 109, at least three first upper rotating rods 110 that are in a one-to-one correspondence with the at least three columns 102, at least three first lower rotating rods 111 that are in a one-to-one correspondence with the at least three columns 102, and at least three supporting rods 112 that are in a one-to-one correspondence with the at least three columns 102. A first end of each of the at least three first upper rotating rods 110 is rotatably connected to the first middle seat 109. A first end of each of the at least three first lower rotating rods 111 is rotatably connected to a second end of a corresponding one of the at least three first upper rotating rods 110. A second end of each of the at least three first lower rotating rods 111 is rotatably connected to the upper connecting seat 103 of a corresponding one of the at least three columns 102. An upper end of each of the at least three supporting rods 112 is rotatably connected to a corresponding one of the at least three first lower rotating rods 111, and a lower end of each of the at least three supporting rods 112 is rotatably connected to the sliding seat 104. The upper canopy frame comprises a second middle seat 113 located below the first middle seat 109, a third middle seat 114 located below the second middle seat 113, at least three second upper rotating rods 115 that are in a one-to-one correspondence with the at least three columns 102, and at least three second lower rotating rods 116 that are in a one-to-one correspondence with the at least three columns 102. A first end of each of the at least three second upper rotating rods 115 is rotatably connected to a corresponding one of the at least three first upper rotating rods 110. A second end of each of the at least three second upper rotating rods is rotatably connected to the second middle seat 113. A first end of each of the at least three second lower rotating rods 116 is rotatably connected to a corresponding one of the at least three second upper rotating rods 115. A second end of each of the at least three second lower rotating rods 116 is rotatably connected to the third middle seat 114, and an elastic body 106 is disposed between the second middle seat 113 and the third middle seat 114.

The plurality of side eave frames comprise the plurality of eave rods 101 and a plurality of supporting mechanisms. Each of the at least three columns 102 is fixedly disposed with a lower connecting seat 107, and the lower connecting seat 107 is located between the upper connecting seat 103 and the sliding seat 104. A first end of each of the plurality of eave rods 101 is connected to the upper connecting seat 103 of a corresponding one of the at least three columns 102. Each of the plurality of supporting mechanisms comprises a telescopic tube 108. A first end of the telescopic tube is rotatably connected to the lower connecting seat 107, a second end of the telescopic tube is rotatably connected to a middle part of a corresponding one of the plurality of eave rods 101. A first locking mechanism 1081 is disposed on the telescopic tube 108. Firstly, unfolding or folding of each of the plurality of side eave frames is independent of unfolding or folding of the canopy frame, so that each of the plurality of side eave frames can be unfolded or folded regardless of whether the canopy frame is unfolded or folded. Additionally, the canopy frame can be unfolded or folded regardless of whether the plurality of side eave frames are unfolded or folded, thereby improving convenience and smoothness of unfolding or folding of the canopy frame. Secondly, the lower connecting seat 107 is located between the upper connecting seat 103 and the sliding seat 104, so as to increase a height of a lower end of each of the plurality of supporting mechanisms and an unfolding angle of each of the plurality of eave rods 101, so that each of the plurality of eave rods 101 can be close to a horizontal position, and an activity space under the plurality of side eave frames is large. Thirdly, the structure is simple and cost is low. The telescopic tube 108 comprises an outer tube 1082 and an inner tube 1083. The outer tube 1082 comprises at least one locking hole that penetrates through an inside and an outside of the outer tube 1082. The first locking mechanism comprises an elastic buckle disposed in the inner tube 1083. The elastic buckle has an elastic member and a positioning column disposed on the elastic member. The inner tube 1083 comprises a through hole that penetrates through an inside and an outside of the inner tube. The positioning column of the elastic buckle extends out of the through hole due to an elastic force of the elastic member, the outer tube 1082 is slidably sleeved outside the inner tube 1083, and the positioning column of the elastic buckle is disposed in one locking hole of the at least one locking hole.

Two side eave frames of the plurality of side eave frames are connected to the upper connecting seat 103 and the lower connecting seat 107 of each of the at least three columns 102, and the two side eave frames of the plurality of side eave frames form a 90 degrees included angle. Each of the two side eave frames is perpendicular to one of the folding frames 105 and in a same direction as the other one of the folding frames 105. Each side of the canopy frame forms a pair of side eave frames of the plurality of side eave frames, and each side of the canopy frame can expand a side eave.

Embodiment 2

A quick disassembly and assembly structure for a frame rod 10 and a canopy fabric 20 of a canopy frame with eaves are shown in FIGS. 11 to 18. The difference between Embodiment 2 and Embodiment 1 is that the connecting portion 32 can be detachably inserted into a port at the outer end of a corresponding one of the plurality of eave rods 101. The connecting portion 32 comprises a pin 323, and the pin 323 can be detachably inserted into the port at the outer end of the corresponding one of the plurality of eave rods 101, so as to facilitate assembly and disassembly of the connecting portion 32 and the corresponding one of the plurality of eave rods 101. When in use, the pin 323 can be inserted into an inner hole at the outer end of the corresponding one of the plurality of eave rods 101. Therefore, firstly, since the plurality of connecting members 30 and the canopy fabric 20 are connected together, the plurality of eave rods 101 and the plurality of connecting members 30 are convenient to be sleeved together, so as to avoid the plurality of eave rods 101 piercing the canopy fabric 20 and extend a service life of the canopy fabric 20. Secondly, since the plurality of connecting members 30 and the canopy fabric 20 are connected together and the plurality of eave rods 101 and the plurality of connecting members 30 are sleeved together, a connection between the plurality of connecting members 30 and the plurality of eave rods 101 is firm and stable. Not only will the connection between the plurality of connecting members 30 and the plurality of eave rods 101 not be separated when the frame rod 10 is folded and not only can the canopy fabric 20 be folded directly after unfolding (there is no need to worry about the plurality of connecting members 30 and the plurality of eave rods 101 being separated after folding), but also an unfolding method of connecting the plurality of connecting members 30 and the plurality of eave rods 101 first and then unfolding the frame rod 10 can be realized, providing a new unfolding or folding method, which is fast, accurate, convenient, and quick to unfold or fold.

A middle of the pin 323 comprises an avoidance hole 324 penetrating through the pin 323 along a lateral direction (i.e., a radial direction of the pin 323), so that the middle of the pin 323 has certain elasticity. An outer peripheral wall of the pin 323 corresponding to the avoidance hole 324 protrudes to form an outward protrusion 325, and a front part of the outward protrusion 325 gradually protrudes from front to back, which is convenient for sleeve connection and improves connection firmness between the pin 323 and the plurality of eave rods 101. The port at the outer end of each of the plurality of eave rods 101 comprises an inner sleeve 50, and the inner sleeve 50 comprises a sleeve body 51 and an annular edge 52 extending outward from a periphery of an opening end of the sleeve body 51. The sleeve body 51 is sleeved in the port at the outer end of a corresponding one of the plurality of eave rods 101, and the annular edge 52 abuts a distal end of the corresponding one of the plurality of eave rods 101. A screw 53 with a diameter gradually increasing from front to back is screwed on a closed end of the sleeve body 51. Therefore, on the one hand, the inner sleeve is provided to improve firmness and convenience of an insertion connection between the port at the outer end of each of the plurality of eave rods 101 and the pin 323. On the other hand, connecting strength between the sleeve body 51 and the plurality of eave rods 101 can be gradually tightened by screwing the screw 53.

The canopy frame comprises at least three columns 102 and an upper canopy frame connected to the at least three columns 102. A top end of each of the at least three columns 102 is fixedly disposed with an upper connecting seat 103, and the upper canopy frame is connected to the upper connecting seat 103. Each of the at least three columns 102 is slidably disposed with a sliding seat 104, and a folding frame 105 is connected to the upper connecting seats 103 and the sliding seats 104 of each pair of adjacent columns of the at least three columns 102. The folding frame 105 comprises a plurality of scissor-shaped connecting rod groups pivotally connected in series. The folding frame 105 has four ends, which are respectively rotatably connected to the upper connecting seats 103 and the sliding seats 104 of each pair of the adjacent columns of the at least three columns 102. The upper canopy frame comprises a first middle seat 109, at least three first upper rotating rods 110 that are in a one-to-one correspondence with the at least three columns 102, at least three first lower rotating rods 111 that are in a one-to-one correspondence with the at least three columns 102, and at least three supporting rods 112 that are in a one-to-one correspondence with the at least three columns 102. A first end of each of the at least three first upper rotating rods 110 is rotatably connected to the first middle seat 109.

A second end of each of the at least three first lower rotating rods 111 is rotatably connected to the upper connecting seat 103 of a corresponding one of the at least three columns 102. An upper end of each of the at least three supporting rods 112 is rotatably connected to a corresponding one of the at least three first lower rotating rods 111, and a lower end of each of the at least three supporting rods 112 is rotatably connected to the sliding seat 104. The upper connecting seat 103 comprises a sliding rail 1031. The plurality of eave rods 101 are at least three eave rods 101 in a one-to-one correspondence with the at least three columns 102. An inner end of each of at least three eave rods 101 can be rotatably connected to a middle of a corresponding one of the plurality of supporting rods 112, and an outer end can move through the sliding rail 1031.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
