[0002] At present, the leg rests used in furniture sofas mainly include one-piece leg rests that are combined with sofas and split leg rests that are made into the shape of small stools. Among them, the one-piece leg rests are produced and manufactured in an integrated manner with the sofa, and generally have the function of being able to stretch in conjunction with the sofa backrest, and are more comfortable. Typical products are various types of "first-class sofas". For users who already have traditional sofas, it is not a suitable choice to update the traditional sofa into a "first-class sofa" with a large investment. Due to its auxiliary nature, the split leg rest can be flexibly adapted to various sofas, and it is cheap and has a wide range of product choices, so the split leg rest has become the choice of most traditional sofa users. In actual use, there are some shortcomings in the split leg rest. Since most of these leg rests are made in the shape of small stools, when the leg rest is not used, the small stool becomes a burden and needs to be stored somewhere. When the leg rest is used, it has to be moved to the front of the sofa, which is quite inconvenient to use. Utility Model Content

[0028] A leg support, such as Figure 1 As shown, it includes a leg support plate 200 rotatably connected to the top of the support seat 100; a limit pin 160 capable of limiting the position of the leg support plate 200 is provided between the leg support plate 200 and the support seat 100; the limit pin 160 can make the leg support plate 200 stably stop at a fixed position; the support seat 100 includes a horizontal portion 110 for support and vertical portions 120 connected to the horizontal portion 110 and located on both sides of the leg support plate 200; the rotating shaft seat 150 is connected to the vertical portion 120; the rotating shaft seat 150 is rotatably connected to the leg support plate 200 through a rotating shaft 151; the limit pin 160 is arranged on the rotating shaft seat 150;

[0029] In one embodiment, the transverse portion 110 and the vertical portion 120 are an integral structure to form an L-shaped support seat 100, that is, the end of the transverse portion 110 is connected to the bottom end of the vertical portion 120; the advantage of using the L-shaped support seat 100 is that when storing, the transverse portion 110 can be completely stored into the bottom of the sofa / chair, and the vertical portion 120 is close to the edge of the sofa / chair, thereby reducing the space occupied; in another embodiment, the transverse portion 110 and the vertical portion 120 can also be set as a split structure; in another embodiment, the transverse portion 110 and the vertical portion 120 can also be set as a "⊥" shape, but this structure does not have a high space utilization rate as the L-shaped structure;

[0030] In one embodiment, a plurality of fixing tubes 130 are connected between the transverse parts 110; the fixing tubes 130 are fixedly connected to the transverse parts 110 by fixing screws 140; the stability between the transverse parts 110 can be increased by providing the fixing tubes 130; the fixing tubes 130 are non-essential components, and the normal use of the leg support will not be affected if they are not installed;

[0031] In another embodiment, the vertical portion 120 is a height adjustment assembly for adjusting the height of the leg rest plate 200; the height adjustment assembly includes a vertical tube 121 connected to the horizontal portion 110; a lengthening tube 124 is slidably connected in the vertical tube 121; a locking inner sleeve 122 is sleeved on the lengthening tube 124; a locking nut 123 is sleeved outside the locking inner sleeve 122; an external thread 1211 threadedly connected to the locking nut 123 is provided at the top of the vertical tube 121; the overall height of the leg rest plate 200 from the ground can be adjusted by the cooperation of the lengthening tube 124 and the vertical tube 121 to adapt to sofas 300 of different heights; when the locking nut 123 cooperates with the external thread 1211, it moves downward to squeeze the locking inner sleeve 122, thereby fixing the position of the lengthening tube 124; in this embodiment, the rotating shaft seat 150 is connected to the top of the lengthening tube 124; the lengthening tube 124 and the rotating shaft seat 150 can be fixed by any one of welding, riveting, crimping, etc.

[0032] In one embodiment, the leg rest plate 200 is processed from wood or plastic with a soft material外敷, has a certain strength, and will not deform under a certain external force.

[0033] In one embodiment, a fixing piece 170 is provided between the rotating shaft seat 150 and the leg rest plate 200; the fixing piece 170 is fixedly connected to the side of the leg rest plate 200 through a plurality of fixing holes 171 provided thereon; the fixing piece 170 is made of a metal material, and the fixing piece 170 is respectively fastened to appropriate positions on the left and right sides of the leg rest plate 200 by screws. The rotating shaft 151 is a constant-height shoulder bolt, and the two rotating shafts 151 respectively pass through the shaft holes on the left and right rotating shaft seats 150 and are fastened to the fixing piece 170, so that the fixing piece 170 and the rotating shaft seat 150 can rotate relative to each other flexibly but can maintain a fixed and small lateral gap and will not fall off the rotating shaft seat 150.

[0034] In one embodiment, when the leg rest plate 200 is in limit fit with the limit pin 160, it is on the same side of the vertical portion 120 as the horizontal portion 110; that is, in the working state, the leg rest is in a "匚" shape.

[0035] In one embodiment, such as Figure 2As shown, a damping assembly for increasing the rotation resistance of the leg support plate 200 is provided between the fixing plate 170 and the rotating shaft seat 150; the damping assembly includes a steel ball holding pressure plate 181 fixedly arranged on the rotating shaft seat 150; the steel ball holding pressure plate 181 is provided with a connecting hole 182 and a clearance hole 183 for being fixedly connected to the rotating shaft seat 150; a positioning steel ball 184 is provided in the clearance hole 183; a positioning spring 185 which is always in a compressed state is provided between the positioning steel ball 184 and the rotating shaft seat 150; the positioning spring 185 abuts against the positioning steel ball 184 so that the positioning steel ball 184 partially exceeds the clearance hole 183 and cooperates with the limiting groove 172 provided on the fixing plate 170; a plurality of limiting grooves 172 are arranged in a ring shape with the rotating shaft 151 as the center; Figure 2 In the figure, four limiting grooves 172 are set. When the leg support plate 200 rotates around the rotating shaft 151 and rotates to a certain angle, the part of the positioning steel ball 184 that exceeds the giving hole 183 cooperates with the limiting groove 172, and the positioning spring 185 abuts against the positioning steel ball 184, which can increase the rotation damping of the leg support plate 200 and increase its rotation safety to avoid the leg support plate 200 suddenly falling due to gravity when it is not firmly grasped; when the leg support plate 200 rotates to a position parallel to the vertical part 120, the positioning steel ball 184 cooperates with the limiting groove 172 to reduce the shaking of the leg support plate 200.

[0036] like Figure 3 As shown, the limit pin 160 cooperates with the fixing plate 170 to limit the position of the leg support plate 200; the limit pin 160 abuts against the lower end of the fixing plate 170, so that the leg support plate 200 cannot be further rotated clockwise in the position shown in the figure, and can only be rotated counterclockwise for storage.

[0037] The working principle of this application is:

[0038] like Figure 4-6 As shown, the support seat 100, the leg support plate 200, and the fixing tube 130 are combined into one body through the above-mentioned connection method. Since the fixing sheet 170 is fastened to the leg support plate 200 as one body, the leg support plate 200 can perform relative rotational movement with the rotating shaft 151 and the rotating shaft seat 150, and the rotating shaft 151 is fixed to the end of one end of the leg support plate 200, and the rotating shaft seat 150 is fixed to the top of the support seat 100, so the leg support plate 200 actually performs a flipping movement around the top of the support seat 100. Since the width of the leg support plate 200 is slightly smaller than the width between the support seats 100, and the fixing tube 130 is fixed between the transverse parts 110, it will not hinder the leg support plate 200 from performing a flipping movement around the top of the vertical part 120, so the leg support plate 200 can perform a 360-degree flipping movement around the top of the vertical part 120.

[0039] Since a limit pin 160 is fixed on each of the two side pivot seats 150, and a fixed and small lateral gap is maintained between the fixing plate 170 and the pivot seat 150, the limit pin 160 relatively protruding from the pivot seat 150 hinders the fixing plate 170 from rotating within a 360-degree range, that is, hinders the leg support plate 200 from performing a 360-degree flipping movement around the top of the vertical portion 120.

[0040] The leg support of the present application is placed on the ground. Under the condition of being stationary, due to the action of gravity, the leg support plate 200 is stationary at a position perpendicular to the ground (such as Figure 5 As shown in FIG. 1 , the leg support plate 200 is parallel to the vertical portion 120, and the side of the leg support plate is L-shaped. The leg support plate is pushed toward the outer side of the sofa 300 cushion, and the horizontal portion 110 enters the bottom of the sofa 300 from the gap between the ground and the bottom of the sofa 300 until the leg support plate 200 and the vertical portion 120 contact the outer side of the sofa cushion. At this time, the leg support plate is in a folded storage state, and the entire leg support plate protrudes from the outer surface of the sofa 300 by less than three centimeters, which does not affect the normal use of the sofa 300.

[0041] When the leg rest is used, the leg rest is pulled out from the outer side of the sofa cushion to a suitable distance, and the leg rest plate 200 is turned about 270 degrees. The limit pin 160 blocks the leg rest plate 200 at the current position and cannot be turned further (such as Figure 4 Or 6), the user can then place the legs on the leg support plate 200 and adjust the distance between the leg support and the sofa 300 as needed to achieve the most comfortable sitting posture.

[0042] When further stored, the leg support plate 200 is Figure 4 Or rotate in the direction of the arrow in 6 to form Figure 5 The storage structure shown is pushed toward the sofa 300 for storage.

[0043] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
