Description

Technical Field

[0001] This utility model relates to the field of chair technology, specifically to a folding wooden bench. Background Technology

[0002] Folding wooden benches are a common type of outdoor and patio furniture. Primarily made of wood, they feature a unique structural design that allows them to be converted between a usable and folded-out state. These benches combine the natural beauty of wooden furniture with the convenience of folding furniture, making them widely used in parks, gardens, balconies, and other locations to meet users' needs for rest at any time. They also save space when not in use, facilitating storage and transportation.

[0003] Currently, most existing folding wooden benches use a hinged structure to achieve their folding function. Common methods include connecting the seat to the leg frame with hinges, allowing the seat to fold upwards; and designing support legs that can fold inwards to reduce the overall footprint. While this type of wooden bench achieves the folding function and improves its storage and portability, it still has the following drawbacks in practical use:

[0004] 1. Most folding wooden benches lack a locking mechanism, resulting in an ineffective locking mechanism between the seat and the supporting components when unfolded. They rely solely on gravity for support, which can easily lead to structural loosening under long-term stress, posing a safety hazard.

[0005] 2. When folded, there are usually no reliable fixing devices between the moving parts, which makes the parts easy to fall apart and shake during transportation. This not only makes operation inconvenient, but also easily causes collisions and damage to the parts. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a folding wooden bench, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A folding wooden bench, comprising:

[0009] The backrest includes two vertical and symmetrically arranged support legs. Lower crossbars are fixedly installed on opposite sides of the two support legs, and upper crossbars are fixedly installed on the top of the two support legs.

[0010] The seat plate, which is hinged to the top of the lower crossbar by a hinge, rotates around the hinge to form two different shapes:

[0011] First configuration: When the seat plate is horizontal, the seat plate is in contact with the side wall of the lower crossbar;

[0012] Second configuration: When the seat plate is vertical, the free end of the seat plate can fit against the side wall of the upper crossbar;

[0013] There are two side support frames, each hinged to one support leg via a second hinge. As the side support frames rotate around the second hinge, they can form two different configurations:

[0014] First configuration: When the seat plate is horizontal, the side support frame is attached to one end of the seat plate;

[0015] Second configuration: When the seat is vertical, the side support frame fits against the side of the seat away from the backrest;

[0016] There are two support blocks. The two support blocks are fixedly installed on the side of the two side support frames that are close to each other. When the side support frame is in contact with the seat plate and the seat plate is horizontal, the bottom of the seat plate is in contact with the top of the support block.

[0017] The fixing mechanism consists of two sets, which are installed on two support blocks respectively and can be connected to the base plate. The fixing mechanism is used to fix or remove the fixing between the support block and the base plate.

[0018] The snap-fit ​​mechanism is installed on the seat plate. When the seat plate is in contact with the backrest and both side support frames are in contact with the side of the seat plate away from the backrest, the snap-fit ​​mechanism can snap into contact with the two side support frames.

[0019] Furthermore: the seat plate includes a fixed frame hinged to the lower crossbar by a hinge, the fixed frame has a mounting hole in the middle, and multiple support rods are fixedly installed on the fixed frame and in the mounting hole in a horizontal linear array.

[0020] The fixing mechanism includes a male buckle fixedly installed on the support block, and a female buckle fixedly installed on the fixing frame and located on the inner side wall of the mounting hole. When the bottom of the seat plate is in contact with the top of the support block, the male buckle can overlap and fix with the female buckle.

[0021] Furthermore: a horizontal reinforcing rod is fixedly installed at the bottom of the seat plate and below the mounting hole. When the seat plate is in contact with the backrest and both side support frames are in contact with the side of the seat plate away from the backrest, the top of the two side support frames is in contact with the bottom of the reinforcing rod, and the snap-fit ​​mechanism is installed on the reinforcing rod.

[0022] Furthermore: the locking mechanism includes two locking rods that are both vertical and can move through the reinforcing rod. The top of each of the two side support frames is provided with a locking hole. When both side support frames are in contact with the side of the seat plate away from the backrest, the bottom ends of the two locking rods can be inserted into the two locking holes respectively and locked with the side support frames.

[0023] Furthermore: the snap-fit ​​rod includes a connecting rod, a limiting plate, and a snap-fit ​​post. The reinforcing rod has a through hole through which the connecting rod can move. The bottom of the reinforcing rod has a receiving hole connected to the through hole. The bottom of the connecting rod is integrally formed with a snap-fit ​​post that can be hidden in the receiving hole. The top is fixedly installed with a limiting plate. The diameter of the limiting plate is the same as the diameter of the snap-fit ​​post, and the diameter of the limiting plate is larger than the diameter of the connecting rod. The cross-section between the connecting rod and the through hole is fitted. The snap-fit ​​post can be inserted into the snap-fit ​​hole and the cross-section between the snap-fit ​​post and the snap-fit ​​hole is fitted.

[0024] Furthermore, a horizontal tie rod is fixedly installed between the two supporting legs on opposite sides and below the lower crossbar.

[0025] Furthermore, multiple columns are fixedly installed in a horizontal linear array between the lower and upper crossbars.

[0026] This utility model provides a folding wooden bench. Compared with the prior art, it has the following advantages:

[0027] 1. When unfolded, the side support frame provides lateral support to one end of the seat plate, the support block provides bottom support for the horizontal seat plate, and the seat plate and support block are locked together by the fixing mechanism to form a stable triangular support structure, which ensures the strength and durability of the seat.

[0028] 2. When folded, the side support frame and the upright seat plate are snapped together by the snap-fit ​​mechanism, so that all moving parts and the backrest are fixed into a rigid whole, which avoids the problem of loose and wobbling parts after folding, facilitates transfer, and effectively prevents damage caused by collision between parts.

[0029] 3. The grid structure of the fixed frame and support rods is lighter and requires less material than solid wood base plates while ensuring sufficient support strength; the overlapping fixing method of male and female buckles is a very intuitive and easy-to-operate connection method. Users can lock and unlock without tools, which greatly improves the user experience and efficiency of the folding and unfolding process. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Example

[0040] To address the technical problems in the background section, the following folding wooden bench is provided:

[0041] Combination Figures 1-6 As shown, the present invention provides a folding wooden bench, comprising:

[0042] The backrest 1 includes two vertical and symmetrically arranged support legs 11. A lower crossbar 12 is fixedly installed on the opposite side of the two support legs 11. An upper crossbar 13 is fixedly installed on the top of the two support legs 11. The upper crossbar 13 and the lower crossbar 12 are fixed to the two support legs 11 by riveting.

[0043] Seat plate 2 is hinged to the top of lower crossbar 12 via hinge 7. Hinge 7 is fixed to seat plate 2 and lower crossbar 12 by screws. When seat plate 2 rotates around hinge 7, it can form two shapes:

[0044] First configuration: When the seat plate 2 is horizontal, the seat plate 2 is in contact with the side wall of the lower crossbar 12;

[0045] Second configuration: When the seat plate 2 is vertical, the free end of the seat plate 2 can be attached to the side wall of the upper crossbar 13;

[0046] There are two side support frames 3, which are respectively hinged to two support legs 11 by hinge 2 8. Hinges 2 8 are fixed to the side support frames 3 and support legs 11 by screws. When the side support frames 3 rotate around hinge 2 8, they can form two different shapes:

[0047] First configuration: When the seat plate 2 is horizontal, the side support frame 3 is attached to one end of the seat plate 2;

[0048] Second configuration: When the seat plate 2 is vertical, the side support frame 3 is attached to the side of the seat plate 2 away from the backrest 1;

[0049] There are two support blocks 4. The two support blocks 4 are fixedly installed on the side of the two side support frames 3 that are close to each other. The support blocks 4 are fixed to the side support frames 3 by riveting. When the side support frame 3 is in contact with the seat plate 2 and the seat plate 2 is horizontal, the bottom of the seat plate 2 is in contact with the top of the support block 4.

[0050] The fixing mechanism 5 consists of two sets, which are respectively installed on two support blocks 4 and can be connected to the base plate 2. The fixing mechanism 5 is used to fix or remove the fixing between the support block 4 and the base plate 2.

[0051] The locking mechanism 6 is installed on the seat plate 2. When the seat plate 2 is in contact with the backrest 1 and both side support frames 3 are in contact with the side of the seat plate 2 away from the backrest 1, the locking mechanism 6 can lock into the two side support frames 3.

[0052] By setting hinge 1 7 and hinge 2 8, the backrest 1, seat 2 and side support frame 3 can rotate, so that the seat 2 and the two side support frames 3 are parallel and close to the backrest 1, which greatly reduces the storage volume, realizes flat folding, and greatly reduces the size of this bench, thus facilitating the storage and transfer of this bench.

[0053] When unfolded, the side support frame 3 provides lateral support to one end of the seat plate 2, and the support block 4 provides bottom support for the horizontal seat plate 2. The seat plate 2 and the support block 4 are then locked together by the fixing mechanism 5, forming a stable triangular support structure that ensures the strength and durability of the seat.

[0054] When folded, the side support frame 3 and the upright seat plate 2 are snapped together by the snap-fit ​​mechanism 6, so that all moving parts and the backrest 1 are fixed into a rigid whole, avoiding the problem of loose and wobbling parts after folding, facilitating transfer, and effectively preventing damage caused by collision between parts.

[0055] Combination Figures 1-6 As shown, the seat plate 2 includes a fixed frame 21 that is hinged to the lower crossbar 12 by a hinge 7. The fixed frame 21 has a mounting hole in the middle. Multiple support rods 22 are fixedly installed on the fixed frame 21 and in the mounting hole in a horizontal linear array.

[0056] The fixing mechanism 5 includes a male buckle 51 fixedly installed on the support block 4. The male buckle 51 is fixedly installed on the support block 4 by screws. A female buckle 52 is fixedly installed on the fixing frame 21 and located on the inner side wall of the mounting hole. The female buckle 52 is fixedly installed on the base plate 2 by screws. When the bottom of the base plate 2 is in contact with the top of the support block 4, the male buckle 51 and the female buckle 52 can overlap and fix each other. It is worth noting that the locking structure is completed by the male buckle 51 and the female buckle 52. The overlapping and fixing method of the male buckle 51 and the female buckle 52 in the locking structure is the prior art and is known to those skilled in the art. It will not be described in detail here.

[0057] The grid structure of the fixed frame 21 and support rod 22 is lighter and requires less material than the solid wood base plate while ensuring sufficient support strength. The overlapping fixing method of male buckle 51 and female buckle 52 is a very intuitive and easy-to-operate connection method. Users can lock and unlock without tools, which greatly improves the user experience and efficiency of the folding and unfolding process.

[0058] Combination Figures 1-6 As shown, a horizontal reinforcing rod 23 is fixedly installed at the bottom of the seat plate 2 and below the mounting hole. Both the reinforcing rod 23 and the support rod 22 are fixed to the fixing frame 21 with iron nails. When the seat plate 2 is in contact with the backrest 1 and both side support frames 3 are in contact with the side of the seat plate 2 away from the backrest 1, the top of the two side support frames 3 is in contact with the bottom of the reinforcing rod 23. The snap-fit ​​mechanism 6 is installed on the reinforcing rod 23. The design of the reinforcing rod 23 further strengthens the structural strength of the seat plate 2 and effectively reduces the deformation caused by force.

[0059] Combination Figures 1-6 As shown, the snap-fit ​​mechanism 6 includes two snap-fit ​​rods 61 that are both vertical and movably pass through the reinforcing rod 23. The top of each of the two side support frames 3 is provided with a snap-fit ​​hole 31. When both side support frames 3 are in contact with the side of the seat plate 2 away from the backrest 1, the bottom ends of the two snap-fit ​​rods 61 can be inserted into the two snap-fit ​​holes 31 respectively and snap-fit ​​with the side support frames 3. The snap-fit ​​rods 61 are inserted into the snap-fit ​​holes 31 to facilitate operation.

[0060] Combination Figures 1-6 As shown, the snap-fit ​​rod 61 includes a connecting rod 611, a limiting plate 612, and a snap-fit ​​post 613. The reinforcing rod 23 has a through hole 231 through which the connecting rod 611 can move. The bottom of the reinforcing rod 23 has a receiving hole 232 connected to the through hole 231. The bottom of the connecting rod 611 is integrally formed with a snap-fit ​​post 613 that can be hidden in the receiving hole 232. The limiting plate 612 is fixedly installed on the top. The diameter of the limiting plate 612 is the same as the diameter of the snap-fit ​​post 613. The diameter of the limiting plate 612 is larger than the diameter of the connecting rod 611. The cross-section between the connecting rod 611 and the through hole 231 is in contact. The snap-fit ​​post 613 can be inserted into the snap-fit ​​hole 31 and the cross-section between it and the snap-fit ​​hole 31 is in contact.

[0061] By utilizing the special design that the diameter of the limiting plate 612 is larger than that of the through hole 231 and the diameter of the limiting plate 612 is the same as that of the snap-fit ​​post 613, the snap-fit ​​rod 61 cannot be completely detached from the reinforcing rod 23 when it is pulled upward through the limiting plate 612, thus effectively preventing the snap-fit ​​rod 61 from falling off.

[0062] The connecting rod 611 fits into the cross section of the through hole 231, and the snap-fit ​​post 613 fits into the cross section of the snap-fit ​​hole 31. This tight fit ensures that the movement trajectory of the snap-fit ​​rod 61 is accurate and without shaking, and the snap-fit ​​stability is high.

[0063] Combination Figures 1-6 As shown, a horizontal tie rod 14 is fixedly installed between the two supporting legs 11 on opposite sides and below the lower crossbar 12. The horizontal tie rod 14 is riveted to the two supporting legs 11. The design of the horizontal tie rod 14 increases the stability between the two supporting legs 11 and improves the stability of this bench.

[0064] Combination Figures 1-6 As shown, multiple columns 15 are fixedly installed in a horizontal linear array between the lower crossbar 12 and the upper crossbar 13. The two ends of the columns 15 are riveted to the lower crossbar 12 and the upper crossbar 13 respectively. The design of the columns 15 increases the stability between the lower crossbar 12 and the upper crossbar 13, thereby increasing the overall stability of the backrest 1.

[0065] Working principle and usage process of this utility model:

[0066] When folding up or moving this bench, the operator releases the overlap between the male buckle 51 and the female buckle 52, separating them. This releases the connection between the support block 4 and the fixed frame 21. At this point, two operators support both ends of the backrest 1 and apply force to the fixed frame 21, causing it to rotate around the hinge 7. This positions the fixed frame 21 in its second configuration, with the seat plate 2 and upper crossbar 13 in contact. Simultaneously, while supporting the backrest 1, the operators also support and position the fixed frame 21. Then, force is applied to the two side support frames 3, causing their free ends to rotate away from the backrest 1 towards the seat plate 2. During this process, the operator manually pulls the limit... The position plate 612 drives the connecting rod 611 to move upward, so that the locking post 613 is hidden in the receiving hole 232. When the side support frame 3 and the seat plate 2 are in contact with the side away from the backrest 1, the top of the side support frame 3 is in contact with the bottom plate of the reinforcing rod 23. When the personnel apply a downward pressing force to the limiting plate 612, the locking post 613 will move downward, so that the locking post 613 is inserted into the locking hole 31 and locked with the side support frame 3. Thus, the reinforcing rod 23 and the side support frame 3 can be positioned. When both side support frames 3 are positioned with the reinforcing rod 23, the bench can be made into a flat object, greatly reducing the volume of the bench, thus facilitating the storage and transfer of the bench.

[0067] When the bench needs to be unfolded for use, the operator manually pulls the limiting plate 612 to move the connecting rod 611 upward, causing the locking post 613 to be hidden in the receiving hole 232. This cancels the positioning state between the reinforcing rod 23 and the side support frame 3. Two operators support the backrest 1 and the fixing frame 21. The two operators manually rotate the two side support frames 3 so that they are in contact with the two support legs 11. The two side support frames 3 are then aligned with the outer ends of the seat plate 2 along its length. The operator then applies a rotational force to the fixing frame 21, causing it to rotate around the hinge 7 to a horizontal position. The fixing frame 21 is then in contact with the top of the two support blocks 4. The operator manually engages the two male buckles 51 with the two female buckles 52, thus fixing the two support blocks 4 to the fixing frame 21, and fixing the two side support frames 3, the seat plate 2, and the backrest 1. The bench is thus unfolded by the two side support frames 3, the seat plate 2, and the backrest 1. The operation is simple.
