Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a telescopic leg support device and furniture. Background Technology

[0002] In situations where prolonged sitting is common, chairs equipped with leg rests can improve comfort, effectively support the legs, and reduce lower back pressure. Leg rests are typically retractable into the chair and can be released only when needed, making them suitable for office workers or students during lunch breaks, as well as for relaxation in various settings.

[0003] Currently, most folding chair leg rests on the market use a rotating structure, similar to those found on car seats. Point A is fixed, and point B rotates around point A. The length of this type of leg rest is limited by the seat height; a longer leg rest requires a higher seat, while a shorter leg rest cannot adequately support the lower legs. Some leg rests are detachable from the seat and can be installed when needed. However, while the length of such a structure is not affected by seat height, installation is cumbersome and inconvenient for storage and use. Additionally, there are telescopic leg rests. However, telescopic leg rests are prone to jamming during extension and retraction, and the overall structure is not stable enough, easily wobbling or rotating downwards during use, resulting in poor support.

[0004] Therefore, it is necessary to provide a telescopic leg support device that is stable in connection, easy to operate, and provides good leg support. Utility Model Content

[0005] The purpose of this invention is to provide a telescopic leg support device that is stable in connection, easy to operate, and provides good leg support.

Detailed Implementation

[0030] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please see Figures 1 to 4This utility model provides a telescopic leg support device 100, applicable to a body 200, which can be a folding chair, office chair, or sofa, etc. The telescopic leg support device 100 is telescopically mounted on the body 200, without affecting the normal use or folding of the body 200. The telescopic leg support device 100 includes a support component 10 and a guide component 20. The support component 10 supports the lower limbs and slides along the guide component 20 to telescopically extend below the body 200. When needed, the support component 10 is pulled to extend beyond the body 200 to support the lower limbs. When not in use, the support component 10 can retract back below the body 200. The structure is simple and easy to operate. When the support component 10 is extended and under pressure, it constantly rests against the body 200. When the support component 10 extends to support the lower limb, it is subjected to force and presses against the body 200 to prevent it from flipping downwards, thus making the overall structure more stable and reliable. On the other hand, the guide component 20 includes at least two guide strips 21, which are located on both sides below the body 200. One end of each guide strip 21 is connected to the body 200, and the other end extends into the support component 10. The support component 10 is fitted onto the guide strips 21 and can slide back and forth along them, allowing it to extend and retract relative to the body 200. It is understood that the guide strips 21, located below the body 200, support and guide the support component 10, which slides along the guide strips 21 on both sides to achieve extension and retraction relative to the body 200.

[0032] After adopting the above technical solution, the telescopic leg support device 100 of this utility model can telescopically move according to actual needs. When support for the lower limbs is needed, it can be extended to support the lower limbs, making it more comfortable to use. When support for the lower limbs is not needed, it can be retracted and placed under the main body 200, making it easy to operate and use. The telescopic leg support device 100 is suitable for the main body 200, which is used for sitting and leaning. The telescopic leg support device 100 is telescopically set on the main body 200 to support the lower limbs. The telescopic leg support device 100 includes a support component 10 and a guide component 20. The support component 10 is used to support the lower limbs and is telescopically set under the main body 200. When the support component 10 is extended and under pressure, the support component 10 is always pressed against the main body 200 to prevent the support component 10 from rotating under force, making the overall structure more stable and reliable. The guide component 20 is used to guide the movement of the support component 10 relative to the main body 200. The guide assembly 20 includes at least two guide strips 21, which are disposed on both sides below the main body 200. One end of each guide strip 21 is connected to the main body 200, and the other end extends into the support assembly 10. The support assembly 10 is sleeved on the guide strips 21 and can slide back and forth along the guide strips 21, allowing the support assembly 10 to extend and retract relative to the main body 200. The telescopic leg support device 100 of this utility model is easy to operate and use, has a stable overall structure, and provides good support.

[0033] Please see Figures 4 to 7In some optional embodiments, the support assembly 10 includes a support member 11 with a hollow inner cavity 111, through which the support member 11 can be fitted onto the guide strip 21. That is, the support member 11 is tubular, allowing the guide strip 21 to slide inside. Specifically, a partition 1112 is provided inside the support member 11, dividing the inner cavity 111 into multiple chambers 1111, each of which can be used for the guide strip 21 to slide. It is understood that if the gap between the guide strip 21 and the support member 11 is large, they will wobble, affecting the performance. To avoid wobble between the guide strip 21 and the support member 11, the space inside the support member 11 should be approximately the same as the outer diameter of the guide strip 21, and slightly larger than the outer diameter of the guide strip 21 so that the guide strip 21 can slide smoothly within the chambers 1111. A partition 1112 is provided, allowing only axial sliding between the guide strip 21 and the support member 11, preventing circumferential rotation. The support member 11 is designed to provide excellent support for the lower limbs, and the partition 1112 divides the inner cavity 111 of the support member 11, allowing the divided cavities 1111 to better engage with the guide strips 21. Each cavity 1111 can engage with one guide strip 21, and multiple guide strips 21 provide better support for the support member 11, making the structure more stable. The guide strips 21 can be arranged horizontally or vertically depending on the distribution of the cavities 1111. In this embodiment, the support member 11 is U-shaped, with each end of the support member 11 fitted onto different guide strips 21. That is, the U-shaped support member 11 has guide strips 21 engaged at both ends, and each end of the support member 11 engages with at least one guide strip 21.

[0034] Please see Figure 6 , Figure 8 and Figure 9In some optional embodiments, the support assembly 10 further includes a limiting member 12, which is installed at the end of the support member 11 that cooperates with the guide strip 21. The limiting member 12 can be sleeved on the end of the support member 11, and both ends of the U-shaped support member 11 are provided with limiting members 12. The limiting member 12 has an installation cavity 121, through which the limiting member 12 is sleeved on the support member 11. On the other hand, the body 200 is provided with a support limiting rod 220 for supporting and limiting. The provision of the support limiting rod 220 can make the structure of the body 200 more stable and can cooperate with the limiting member 12. Specifically, the limiting member 12 can slide along the guide strip 21 with the support member 11 until the limiting member 12 contacts the end of the guide strip 21 connected to the body 200, or the limiting member 12 can slide along the guide strip 21 with the support member 11 until the limiting member 12 contacts the support limiting rod 220. Understandably, when the entire support assembly 10 slides along the guide bar 21 to the end where the guide bar 21 connects to the body 200, the entire support assembly 10 retracts into the lower part of the body 200. Additionally, when the entire support assembly 10 slides along the guide bar 21 to the point where the limiting member 12 contacts the support limiting rod 220, the entire support assembly 10 protrudes outside the body 200.

[0035] Please see Figures 1 to 5 and Figure 8 and Figure 9In some optional embodiments, the limiting member 12 includes a connecting portion 122 that mates with the support member 11, and a mounting cavity 121 is formed within the connecting portion 122. The limiting member 12 also includes a limiting portion 123 that mates with the support limiting rod 220, with the limiting portion 123 protruding from one end of the connecting portion 122. When the limiting member 12 slides along the guide bar 21 with the support member 11 until the limiting portion 123 contacts the support limiting rod 220, the entire support assembly 10 protrudes beyond the body 200 to support the lower limbs. By cooperating with the support limiting rod 220, the cooperation between the limiting member 12 and the support limiting rod 220 can prevent the support assembly 10 from sliding away from the guide assembly 20, resulting in a compact and stable structure. When the support member 11 slides along the guide bar 21, the abutment portion 125 can abut against the seat post 210, or have a certain gap between it and the seat post 210. The abutment portion 125 is located at the end of the connecting portion 122 away from the limiting portion 123, that is, the abutment portion 125 is located at the top end of the connecting portion 122, and the limiting portion 123 is located at the bottom end of the connecting portion 122. In some embodiments, the abutment portion 125 may also be provided with an abutment groove 126, so that the seat tube 210 is located in the abutment groove 126, thereby better limiting the sliding of the entire support member 11, so that the support member 11 can only slide axially along the guide strip 21, and the overall structure is more stable and reliable. Specifically, when the support member 11 slides out of the body 200 and is supported by force, the limiting member 12 is located below the body 200 and the abutment portion 125 at the top end of the limiting member 12 abuts against the seat tube 210. The abutting part 125 abuts against the seat post 210, which can effectively prevent the support member 11 from rotating around the support limit rod 220 when supporting the lower limbs. The seat post 210 above the support assembly 10 presses against the limit member 12, and the support limit rod 220 below the support assembly 10 supports the support assembly 10, making the structure of the support assembly 10 more stable and reliable when supporting the lower limbs.

[0036] Please see Figures 1 to 3 In some optional embodiments, the support limiting rod 220 is located below the support assembly 10 to support the support assembly 10, and the limiting part 123 protrudes below the connecting part 122 and cooperates with the support limiting rod 220. Moreover, the support limiting rod 220 is provided on the support leg at the front of the main body 200, which can make the overall structure more stable.

[0037] Please see Figures 1 to 4 and Figure 6 , Figure 8 and Figure 9In some optional embodiments, the support assembly 10 further includes an inner support member 13, which is disposed between the two limiting members 12, or between the support members 11. In this embodiment, a limiting member 12 is installed at each end of the U-shaped support member 11. A mounting portion 124 is protruding from one side of the limiting member 12, and a hole is opened in the mounting portion 124. The inner support member 13 is installed in the mounting portion 124. The support member 11, the limiting member 12, and the inner support member 13 make the entire support assembly 10 form a frame. The inner support member 13 can effectively prevent the support member 11 from deforming, and the overall structure is more stable and reliable.

[0038] Please see Figures 1 to 4 and Figure 6 In some optional embodiments, one end of the guide bar 21 is connected to the body 200 and bent to form a sliding space 211 for the support member 11 to slide. The guide bar 21 is disposed below the body 200 and includes a connecting end 212 connected to the body 200 and a sliding end 213 that cooperates with the support member 11. In order to enable the guide bar 21 to better allow the support member 11 to slide, the side of the guide bar 21 near the connecting end 212 is bent to form a sliding space 211 for the support member 11 to slide, thereby allowing the support member 11 to slide smoothly below the body 200 without interfering with each other.

[0039] Please see Figures 1 to 3 This utility model provides a piece of furniture 1000, including a support body 200 that can be folded for storage, and a telescopic leg support device 100, which can extend and retract relative to the body 200. A first fabric cover 101 for supporting the lower limbs is fitted onto the telescopic leg support device 100, and a second fabric cover 201 for sitting is fitted onto the body 200. The body 200 includes a seat post 210, on which the second fabric cover 201 for sitting is fitted. Furthermore, a support member 11 is fitted with the first fabric cover 101 for supporting the lower limbs, and after the first fabric cover 101 is fitted onto the support member 11, an end is left that connects to a limiting member 12. With the above technical solution, the furniture 1000 of this utility model, equipped with the telescopic leg support device 100, can support the lower limbs according to actual usage needs, is easy to operate and use, and has a stable overall structure and good support effect.
