FIELD OF THE DISCLOSURE

The present disclosure relates to furniture and in particular to a frame structure of the furniture.

BACKGROUND OF THE DISCLOSURE

Nowadays, most bedroom frame beds available in the market are connected by bolts and are accompanied by a large number of bolt and nut parts upon purchase. With the increasing popularity of online shopping, many people prefer to buy beds online and install them at home by themselves. However, the large number of parts can make installation cumbersome, and screwing bolts into wooden beds can pose risks of damaging the wooden structure due to screws becoming tilted while tightening. Moreover, ordinary screws and nuts require full tightening and have a long rotation stroke that takes significant time during the disassembly and assembly processes. For the convenience of transportation, manufacturers assemble board parts by splicing narrow boards, which makes using bolts and nuts for installation labor-intensive. When bolt holes are not reserved on the bed board, it also takes a lot of time to determine the position of each bolt. To ensure that customers have sufficient parts, manufacturers often provide extra screws and nuts and provide installation tools. However, after the installation is complete, these installation tools and excess spare parts become a waste of resources.

Furthermore, different furniture pieces require unique frame structure parts making them difficult or impossible to reuse for other furniture pieces.

Embodiment 1

Referring to FIGS. 1 to 11, this embodiment provides a single bed (i.e., twin bed), and the single bed comprises an expandable frame structure. The expandable frame structure specifically comprises a first outer frame 1, a second outer frame 2 opposite to the first outer frame 1, and seven lateral rods 3 disposed between the first outer frame 1 and the second outer frame 2.

A plurality of connecting members 4 are respectively separably connected to the first outer frame 1 and a first lateral rod 3 of the seven lateral rods 3, two adjacent lateral rods 3 of the seven lateral rods 3, and a second lateral rod 3 of the seven lateral rods 3 and the second outer frame 2 (e.g., the first lateral rod 3 and the second lateral rods 3 can be a same lateral rod 3). In this way, a width of the single bed can be adjusted by increasing or decreasing a number of the lateral rods 3 of the seven lateral rods 3 to meet the needs of different placing positions of the single bed.

In order to connect the first outer frame 1 and the first lateral rod 3, the two adjacent lateral rods 3, and the second lateral rod 3 and the second outer frame 2 through the plurality of connecting members 4, a first side of the first outer frame 1, a second side of the second outer frame 2 facing the first side, and two sides of each of the seven lateral rods 3 along a thickness direction of each of the seven lateral rods 3 comprise a plurality of connecting fitting members that cooperate with the plurality of connecting members 4 (e.g., the first side of the first outer frame 1, the second side of the second outer frame 2 facing the first side, and the two sides of each of the seven lateral rods 3 each comprise one or more connecting fitting members).

The plurality of connecting fitting members are protrusions 31 protruding outward along a thickness direction of the first outer frame, the second outer frame, or the seven lateral rods 3. Taking one or more protrusions 31 of the protrusions 31 on each of the seven lateral rods 3 as an example (i.e., the first outer frame 1 and the second outer frame 2 have a same structure), two sides of the one or more protrusions 31 in a width direction of the one or more protrusions 31 comprise a guiding rail 311 extending along a height direction, and two ends of the one or more protrusions 31 in the height direction respectively comprise an inlet 312 and an outlet 313 in communication with the guiding rail 311 to facilitate a corresponding one of the plurality of connecting members 4 to enter or leave the guiding rail 311.

Moreover, in order to facilitate the corresponding one of the plurality of connecting members 4 entering the inlet 312, the inlet 312 is an inclined opening to increase an area of the inlet 312. In this way, users can easily place the corresponding one of the plurality of connecting members 4 in the guiding rail 311 without completely aligning the guiding rail 311 with the corresponding one of the plurality of connecting members 4.

Further, each of the plurality of connecting members 4 comprises one or more ribs 41 slidably matched with the guiding rail 311 (e.g., each of the plurality of connecting members 4 comprises two sets of the one or more ribs 41 to cooperate with two adjacent connecting fitting members of the plurality of connecting fitting members, or the one or more ribs 41 cooperate with two adjacent connecting fitting members of the plurality of connecting fitting members). A distal end of the one or more ribs 41 along the height direction comprises a guiding inclined surface 411 configured to be matched with the inclined opening in a guiding manner. A distal end of the guiding inclined surface 411 is connected to the one or more ribs 41 through a first positioning surface 412. When the one or more ribs 41 are inserted into the guiding rail 311, an area of an insertion end (i.e., of the one or more ribs 41) is reduced through the guiding inclined surface 411, and an area of the inlet 312 is increased through the inclined opening, thereby enabling the one or more ribs 41 to be very easily inserted into the inlet 312. When the one or more ribs 41 pass through the outlet 313, the first positioning surface 412 can be matched with an outer wall of the outlet 313 to enable the one or more ribs 41 to be inhibited from moving against an insertion direction of the one or more ribs 41.

Moreover, in addition to a width size of the single bed being adjustable, a length size of the single bed also needs to be adjusted. Therefore, the first outer frame 1 and the second outer frame 2 each comprise an inner tube 11, an outer tube 12 movably connected to the inner tube 11 along a length direction of the first outer frame 1 or the second outer frame 2, and an adjustment member 13 for adjusting a relative position of the inner tube 11 and the outer tube 12. Taking the inner tube 11, the outer tube 12, the adjustment member 13 of the first outer frame 1 as an example, the inner tube 11 and the outer tube 12 can be fixedly connected at different relative positions through the adjustment member 13, thereby changing an overall length of the first outer frame 1 and the second outer frame 2.

In this embodiment, the inner tube 11 comprises a plurality of connection holes 111 at intervals along the length direction of the first outer frame 1, and the adjustment member 13 is disposed on the outer tube 12 to be connected to different connection holes 111 of the plurality of connection holes 111, so as to adjust an extension length of the inner tube 11 relative to the outer tube 12. In this embodiment, the plurality of connection holes 111 are threaded holes, and the adjustment member 13 is a positioning knob. A threaded section of the adjustment member 13 extends into and is connected to one of the threaded holes, and a remaining part of the adjustment member 13 is exposed on a surface of the outer tube 12 as an operating part for the users to operate. The users can disengage the positioning knob from a current connection hole 111 of the plurality of connection holes 111 by rotating the operating part, thereby releasing a locked state of the inner tube 11 and the outer tube 12. The users can pull the inner tube 11 outward or push the inner tube 11 inward as needed, align another connection hole 111 of the plurality of connection holes 111 of the inner tube 11 with the positioning knob, and then the positioning knob is rotated in an opposite direction again, so that the positioning knob can enter the connection hole 111, thereby locking the inner tube 11 and the outer tube 12 together again.

After a length of the first outer frame 1 and the second outer frame 2 is changed, a length of an inner frame (i.e., the seven lateral rods 3) needs to be changed. Therefore, each of the seven lateral rods 3 comprises an inner rod 33 and an outer rod 32 movably connected to the inner rod 33 along the length direction. Different from the first outer frame 1 and the second outer frame 2, a number of the seven lateral rods 3 is relatively large, so it would be troublesome if each of the seven lateral rods 3 is disposed with a same adjustment member 13 as the first outer frame 1 and the second outer frame 2 for length adjustment.

In this embodiment, since a final product of the expandable frame structure is the single bed, two opposite ends of the inner rod 33 and the outer rod 32 and two opposite ends of the inner tube 11 and the outer tube 12 are each disposed with a supporting leg 331. These supporting legs 331 can reliably and stably support the expandable frame structure, a mattress placed on the expandable frame structure, and the users.

Therefore, in this embodiment, the length adjustment is performed through a lateral rod clamping member 5, which is used to connect some of the seven lateral rods 3 between the first outer frame 1 and the second outer frame 2 together. Since the seven lateral rods 3 have been connected together through the plurality of connecting members 4, as long as some of the seven lateral rods 3 are fixedly connected together through the lateral rod clamping member 5, all of the seven lateral rods 3 can be kept at a same length. This avoids the trouble of individually adjusting each of the seven lateral rods 3.

In this embodiment, the lateral rod clamping member 5 is connected to four lateral rods 3 of the seven lateral rods 3. Therefore, the lateral rod clamping member 5 comprises three position-limiting blocks 51, and each of the three position-limiting blocks 51 is disposed between adjacent lateral rods 3 of the four lateral rods 3 of the seven lateral rods 3. Adjacent position-limiting blocks 51 of the three position-limiting blocks 51 define two first slots 52 for receiving two of the four lateral rods 3 of the seven lateral rods 3.

In order to enable another two of the four lateral rods 3 of the seven lateral rods 3 to be connected by the lateral rod clamping member 5, two sides of the three position-limiting blocks 51 facing away from each other comprise two buckling walls 53 extending downward along the height direction, and outsides of the two buckling walls 53 are disposed with two blocking plates 54. Two second slots 55 for receiving another two of the four lateral rods 3 of the seven lateral rods 3 are defined between the two buckling walls 53 and the two blocking plates 54. Through the two second slots 55, another two of the four lateral rods 3 of the seven lateral rods 3 can be connected, thereby enabling the four lateral rods 3 of the seven lateral rods 3 to be connected together.

In this embodiment, a length of the two buckling walls 53 extending downward along the height direction is greater than a length of the two blocking plates 54. Distal ends of the two buckling walls 53 in the height direction extend in a horizontal direction to define a second positioning surface 531 configured to be matched with a bottom of the four lateral rods 3 to inhibit upward movement of the lateral rod clamping member 5 along the height direction. In this way, when the lateral rod clamping member 5 is installed, a top of the lateral rod clamping member 5 is matched with a top of the four lateral rods 3 to inhibit downward movement of the lateral rod clamping member 5 along the height direction, and the second positioning surface 531 is matched with a bottom of the four lateral rods 3 to inhibit upward movement of the lateral rod clamping member 5 along the height direction.

Embodiment 2

Referring to FIG. 12, a piece of furniture defined by the expandable frame structure in this embodiment is a short stool. Specifically, the inner tube 11 and the inner rod 33 are respectively retracted into the outer tube 12 and the outer rod 32. The short stool can be defined by the first outer frame 1 and the second outer frame 2 disposed opposite to each other and four lateral rods 3 disposed between the first outer frame 1 and the second outer frame 2. Since there are exactly four lateral rods 3 in this embodiment, all of the four lateral rods can be connected together by the lateral rod clamping member 5.

Embodiment 3

Referring to FIG. 13, the difference between this embodiment and Embodiment 2 is that the short stool is changed into a long stool, and it is only necessary to extend the inner tube 11 and the inner rod 33 respectively from the outer tube 12 and the outer rod 32 to a desired length.

Embodiment 4

Referring to FIG. 14, the difference between this embodiment and Embodiment 1 is that Embodiment 1 provides the single bed, while this embodiment provides thirteen lateral rods 3 to obtain a double bed (e.g., a full, queen, etc. bed).

Embodiment 5

Referring to FIGS. 15 and 16, the difference between this Embodiment and Embodiment 4 is that in Embodiment 5, by shortening a length of some of the thirteen lateral rods 3 and the second outer frame 2, a parent-child bed is obtained, in which a length of a first area is relatively long, suitable for adults, and a second area is relatively short, suitable for children. In addition, a setting position of the lateral rod clamping member 5 in this embodiment is relatively special, and parts of the thirteen lateral rods 3 in the two areas are connected together, such as two lateral rods 3 of the thirteen lateral rods 3 in the second area and two lateral rods 3 of the thirteen lateral rods 3 in the first area. In this way, it can be ensured that the thirteen lateral rods 3 in the two areas are stably connected together.

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.
