Description

Technical Field

[0001] This utility model relates to the field of sofa component design, and in particular to a sliding sofa support. Background Technology

[0002] A sofa is a common piece of furniture, primarily used for rest. The sofa frame is an important component, serving as the foundation supporting the entire sofa structure.

[0003] Most sofa frames are nowadays fixed in shape, and their structure cannot be easily adjusted after installation. As a result, sofas made with such frames are generally fixed as well, which leads to a fixed and often small usable space for the sofa.

[0004] To address the aforementioned issues, some sofa frames now feature a sliding section. This section can be moved to extend the sofa frame when needed, thereby increasing the length of the sofa that can be made and thus expanding the usable space.

[0005] However, the movable parts of existing sofa frames are mostly driven by manual pulling and pushing, which is time-consuming and laborious. In addition, the movement of this part is prone to problems such as excessive movement, which can damage the sofa frame or the sofa. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The present invention relates to a sliding sofa support, comprising a fixed support 1, a sliding support 2, a guide rail 3, a slider 4, a drive mechanism 5, and a limiting mechanism 6.

[0023] The fixed support 1 includes a base frame 11, a backrest frame 12, and an armrest frame 13. The backrest frame 12 is fixedly connected to the top of one end of the base frame 11 by welding. Preferably, there are two armrest frames 13, which are fixedly connected to the top of both sides of the base frame 11 by welding.

[0024] The fixed bracket 1 also includes a base 14, which can be multiple. In this embodiment, six base 14 are preferred, and all six base 14 are fixedly connected to the bottom of the base frame 11 by connecting rods.

[0025] Preferably, there are two guide rails 3, both of which are fixedly mounted on the base 11 of the fixed bracket 1 by screws. There are also two sliders 4, which are slidably disposed on the two guide rails 3 respectively, that is, the sliders 4 can slide along the guide rails 3 they are on.

[0026] The bottom of the translation bracket 2 is fixedly connected to the two sliders 4 by screws.

[0027] This sliding sofa support also includes rollers 7 and roller brackets 8. Preferably, there are two rollers 7 and two roller brackets 8. Both roller brackets 8 are fixedly connected to the bottom of the sliding support 2 by welding, and the two rollers 7 are rotatably mounted on the roller brackets 8 by pins.

[0028] The drive mechanism 5 includes a linear motor and a guide block 53. The linear motor can be a commercially available linear motor, which includes a motor 51 and a slide rail 52. The motor 51 is hinged to the translation bracket 2 via a pin, and one end of the motor 51 is connected to the slide rail 52. The other end of the slide rail 52 is fixedly connected to the translation bracket 2 by screws. The guide block 53 is fixedly installed on the fixed bracket 1 by screws, and the slide rail 52 can slide relative to the guide block 53. Thus, under the operation of the motor 51, the slide rail 52 can move linearly along the guide block 53, that is, the drive mechanism 5 can drive the translation bracket 2 to move linearly relative to the fixed bracket 1.

[0029] The limiting mechanism 6 includes a first link 61 and a second link 62. The side of the first link 61 is provided with a first protrusion 611 and a second protrusion 612. The base frame 11 of the fixed bracket 1 is provided with a crossbeam 111. The crossbeam 111 is provided with a protrusion. The first protrusion 611 and the protrusion on the crossbeam 111 of the fixed bracket 1 are hinged by a pin, so that the first link 61 can rotate around the hinge point of the first protrusion 611 and the fixed bracket 1. When the first link 61 rotates in one direction to be perpendicular to the crossbeam 111, the end of the first link 61 can abut against the crossbeam 111 to prevent the first link 61 from continuing to rotate in that direction.

[0030] The second protrusion 612 is hinged to one end of the second connecting rod 62 by a pin, so that end of the second connecting rod 62 can rotate relative to the second protrusion 612. The translation bracket 2 is provided with a vertical block 21, and a connecting plate 22 is provided on the end of the vertical block 21. The other end of the second connecting rod 62 is hinged to the connecting plate 22 on the translation bracket 2 by a pin, so that end of the second connecting rod 62 can rotate relative to the translation bracket 2.

[0031] In use, this sliding sofa support allows a portion of the sofa body to be connected to the base frame 11 of the fixed support 1. This portion is fixed and, after connection, forms a cavity between this portion of the sofa body and the fixed support 1. The backrest frame 12 connects to the sofa backrest, and the armrest frame 13 connects to the sofa armrests. The sliding support 2 connects to another portion of the sofa body, which is movable.

[0032] Normally, the translation bracket 2 and the part of the sofa body connected to it are in the receiving cavity. At this time, the end of the first connecting rod 61 on the limiting mechanism 6 abuts against the crossbeam 111 to limit the setting position of the translation bracket 2 and prevent the translation bracket 2 from going too deep into the receiving cavity and causing damage to other structures.

[0033] When a user needs to use a longer sofa body, the linear motor can be activated, causing the slide rail 52 to move outward along the guide block 53. This allows the sliding bracket 2 and the connected sofa body portion to be moved out of the receiving cavity for user use. Additionally, when the sliding bracket 2 moves, the second link 62 moves accordingly, which in turn drives the first link 61 to move. The lengths of the first and second links 61 limit the outward movement of the sliding bracket 2, preventing excessive movement and damage to other structures.

[0034] When it is desired to hide the sofa body part on the sliding bracket 2, the linear motor can be activated to move the slide rail 52 inward along the guide block 53, thereby resetting the sliding bracket 2 and the connected sofa body part to be placed back in the accommodating cavity.

[0035] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
