Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically a retractable sofa. Background Technology

[0002] A sofa is a type of furniture, a cushioned seat with armrests on both sides, mainly placed in the living room for resting, chatting, or watching TV. The sofa frame is made of wood or steel, and the lining is made of cotton and other foam materials, making it generally comfortable.

[0003] With the increasing popularity of storage in modern homes, modern sofas have evolved from simple seats into storage containers. While sofas can be used for storing items, typical foldable sofas only use a single drawer. This makes it difficult to effectively compress easily compressible or expandable items such as down jackets or quilts when stuffing them into the drawer. As a result, these items are squeezed into the drawer and take up a lot of space, hindering storage and limiting the sofa's usability. Furthermore, as objects are compressed laterally, they also compress and rub against the sofa body that guides the drawer, easily causing wear and tear.

[0004] To address this issue, those skilled in the art have proposed a retractable sofa. Utility Model Content

[0005] The purpose of this invention is to provide a retractable sofa to solve the problem mentioned in the background art of effectively compressing and storing easily compressible and easily expandable objects.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A retractable sofa includes a main body and also includes:

[0008] A storage mechanism connected to the main body of the sofa includes a guide sleeve fixedly connected to the main body of the sofa. The guide sleeve is slidably connected to a drawer. Two sets of parallel guide rails are fixedly installed inside the drawer. A locking component is slidably installed on each set of guide rails. The two sets of locking components are fixedly connected to a set of shelves slidably installed inside the drawer. The shelf has multiple sets of longitudinal grooves. The multiple sets of longitudinal grooves are slidably connected to a set of slide rods. The slide rods are fixedly connected to multiple sets of linearly arranged pressure plates. The multiple sets of pressure plates are fixedly connected to a set of stop bars. The shelf has notches that match the size of the pressure plates.

[0009] The support and adjustment mechanism is connected to the main body of the sofa.

[0010] As a further improvement of this utility model: the locking assembly includes a slider that is slidably connected to the guide rail, the slider being fixedly connected to the spacer, the slider being threadedly connected to a lead screw, the lead screw being coaxially fixedly connected to a friction pad that abuts against the guide rail, and the lead screw being coaxially fixedly connected to a paddle.

[0011] As a further improvement of this utility model: the support adjustment mechanism includes two sets of support frames that are slidably connected to the sofa body. Each support frame is threadedly connected to a set of screws. Each screw is fixedly connected to a rotating frame. The rotating frame is rotatably connected to the sofa body. The rotating frame is hinged with a hexagonal head. The sofa body is snapped with an armrest pad. A receiving cavity is provided below the armrest pad and opened in the sofa body. The hexagonal head is located in the receiving cavity.

[0012] As a further improvement of this utility model: multiple sets of rollers are rotatably installed at the bottom of the sofa body, and the support frame is provided with through grooves that are adapted to the size of the rollers.

[0013] As a further improvement of this utility model: the drawer is fixedly connected with a flexible handle, which is made of fabric.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Under normal circumstances, the height of the sofa body is adjusted via the support adjustment mechanism. When storage is needed, the drawer is pulled out from the guide sleeve for easy storage. When an object needs to be compressed, it is placed in the drawer, and then the pressure plate is rotated. Due to the movement of the sliding rod, all pressure plates rotate synchronously, then the partition moves, causing it to compress the object, with the pressure plate pressing down on top of the object. The locking component is then locked to restrict its movement on the guide rail, thus limiting the movement of the partition. The presence of a stop bar, which abuts against the partition, limits the rotation angle of the pressure plate, preventing excessive deformation of the object longitudinally and ensuring smooth drawer operation. This invention, through structural adjustments to the storage mechanism, not only provides conventional storage but also facilitates the storage of easily expandable and compressible objects. It is highly versatile, saves space, and prevents wear and tear on objects compressed by the storage mechanism. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] Example 1, see Figures 1-5 As shown, a retractable sofa includes a sofa body 1, and also includes:

[0024] The storage mechanism 2 is connected to the sofa body 1. The storage mechanism 2 includes a guide sleeve 3 fixedly connected to the sofa body 1. The guide sleeve 3 is slidably connected to a drawer 4. Two sets of parallel guide rails 5 are fixedly installed inside the drawer 4. A locking component 6 is slidably installed on each set of guide rails 5. The two sets of locking components 6 are fixedly connected to a set of partitions 7 slidably installed inside the drawer 4. The partitions 7 have multiple sets of longitudinal grooves 8. The multiple sets of longitudinal grooves 8 are slidably connected to a set of slide rods 9. The slide rods 9 are fixedly connected to multiple sets of linearly arranged pressure plates 10. In the natural state, the pressure plates 10 are in a hanging state. The multiple sets of pressure plates 10 are fixedly connected to a set of baffles 11. The partitions 7 have notches 12 that are adapted to the size of the pressure plates 10. The notches 12 are used to accommodate the pressure plates 10.

[0025] The support and adjustment mechanism 13 is connected to the main body of the sofa 1.

[0026] Under normal circumstances, the height of the sofa body 1 is adjusted by the support adjustment mechanism 13. When the present invention is needed for storage, the drawer 4 is pulled out from the guide sleeve 3 for easy storage. When the object placed in the drawer 4 needs to be compressed by squeezing, the object to be compressed is placed in the drawer 4, and then the pressure plate 10 is rotated. Due to the drive of the slide rod 9, each set of pressure plates 10 rotates synchronously. Then the partition 7 is moved so that the partition 7 squeezes the object, and the pressure plate 10 presses on the object. Then the locking component 6 is locked to restrict the movement of the locking component 6 on the guide rail 5, thereby restricting the movement of the partition 7. Due to the setting of the stop bar 11, the rotation angle of the pressure plate 10 is restricted by the mutual abutment between the stop bar 11 and the partition 7, thereby avoiding excessive deformation and expansion of the object in the longitudinal direction, so as to ensure that the drawer 4 is pulled out smoothly and also to avoid wear and tear on the object. By adjusting the structure of the storage mechanism 2, this invention not only provides conventional storage but also makes it easier to store objects that are easily expanded or compressed. It is highly versatile, helps save space, and prevents wear and tear on objects compressed by the storage mechanism 2.

[0027] In one embodiment, the locking assembly 6 includes a slider 14 slidably connected to the guide rail 5, a fixed connection between the slider 14 and the spacer 7, a lead screw 15 threadedly connected to the slider 14, a friction pad 16 coaxially fixedly connected to the lead screw 15 and a lever 17 coaxially fixedly connected to the lead screw 15. By moving the lever 17, the lever 17 drives the lead screw 15 to rotate, causing the lead screw 15 and the slider 14 to rotate helically. This causes the lead screw 15 to move the friction pad 16. When the friction pad 16 presses against the guide rail 5, the friction pad 16 provides friction for the movement of the slider 14, thereby restricting the movement of the slider 14 and thus restricting the movement of the spacer 7.

[0028] In one embodiment, the support adjustment mechanism 13 includes two sets of support frames 18 slidably connected to the sofa body 1. Each support frame 18 is threadedly connected to a set of screws 19. Each screw 19 is fixedly connected to a rotating frame 20, which is rotatably connected to the sofa body 1. The rotating frame 20 is hinged with a hexagonal head 21. An armrest pad 22 is snapped onto the sofa body 1. A receiving cavity 23 is provided below the armrest pad 22 within the sofa body 1, and the hexagonal head 21 is disposed within the receiving cavity 23. After removing the armrest pad 22, the hexagonal head 21 is rotated, causing its end to extend out of the sofa body 1. A wrench is then used to clamp the hexagonal head 21 and rotate it, causing the rotating hexagonal head 21 to rotate, which in turn rotates the screws 19. The rotating screws 19 drive the support frames 18 and the sofa body 1 to move, thereby adjusting the height of the sofa body 1.

[0029] In one embodiment, multiple sets of rollers 24 are rotatably mounted on the bottom of the sofa body 1, and the support frame 18 has through grooves 25 that are adapted to the size of the rollers 24. By setting the rollers 24 and the through grooves 25, the rollers 24 can pass through the through grooves 25 to contact the ground, thereby facilitating the movement of this utility model.

[0030] Example 2, based on Example 1, see [link / reference] Figures 1-3 The drawer 4 is fixedly connected to a flexible handle 26, which is made of fabric. By providing a flexible handle 26 made of fabric, it is easy for people to pull the drawer 4 while avoiding injury caused by bumping into the flexible handle 26.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
