TECHNICAL FIELD
[0001] The utility model relates to the field of home, concretely relates to a base with hidden foot rest function and chair. BACKGROUND
[0002] In the prior art, the design of the conventional chair mainly focuses on the basic function of supporting the sitting posture of the human body, and the structure thereof is usually composed of a base, a cushion, a backrest and an armrest. However, in view of the foot support requirement of the user during long time sitting or lying, the prior art has the following significant defects and limitations: most conventional chairs (such as office chairs, dining chairs and sofas) are not equipped with a foot rest function, and the user needs to use an independent foot stool or foot rest plate additionally, which leads to redundant space occupation and complicated use process. For example, the user needs to get up to take and place the foot stool, which destroys the continuity of use. A small number of chairs equipped with a foot rest (such as some leisure chairs or recliners) usually adopt an external folding structure, which destroys the overall appearance of the chair when the foot rest is exposed, affects the aesthetic coordination of the indoor space, and is inconvenient to store, and still has a protrusion or gap after being folded, which is easy to interfere with other parts (such as rollers and supports) of the base. SUMMARY
[0003] To solve the above technical problems, the utility model provides a base with hidden foot rest function and chair, which can pull out the foot rest structure during use, and hide under the base body when not in use.

DETAILED DESCRIPTION
[0025] In order to facilitate the understanding of the technical scheme of the present application, the following will be described in detail in combination with the drawings and specific embodiments.
[0026] Embodiment 1
[0027] As Figures 1-3 indicated, a base with a hidden foot support function includes a base body 1 and a mobile foot support 2:
[0028] The base body 1 includes a seat part 1-1 and a supporting leg 1-2, and the seat part 1-1 and the supporting leg 1-2 enclose a containing space 1-3.
[0029] The mobile foot support 2 is slidingly fitted in the containing space 1-3 and includes a sliding frame 2-1, a foot support plate 2-2 located on the sliding frame 2-1, and a baffle 2-3 located at one end of the sliding frame 2-1.
[0030] The base has a first state, and in the first state, the sliding frame 2-1 and the foot support plate 2-2 are retracted in the containing space 1-3, and the baffle 2-3 is located at the entrance of the containing space 1-3.
[0031] When the foot support function is not used, by completely retracting the mobile foot support 2 into the containing space 1-3 of the base body 1, the foot support plate 2-2 and the sliding frame 2-1 are located below the base body 1, eliminating the visual obtrusiveness of the traditional external foot support and maintaining the simplicity and integrity of the appearance of the base.
[0032] In addition, the mobile foot support 2 is linearly slidingly fitted with the containing space 1-3 through the sliding frame 2-1, which reduces the wear of the moving parts compared with the traditional hinged folding structure, prolongs the service life, and the sliding track is controllable, reducing the risk of shaking or deviation during the unfolding / storage process.
[0033] Meanwhile, in the first state (i.e. the storage state), the baffle 2-3 closes the front entrance of the accommodation space 1-3, preventing dust and debris from entering the slide rail or the interior of the accommodation space 1-3, reducing the cleaning frequency and maintenance cost, and avoiding mechanical failure caused by foreign matter jamming.
[0034] The base has a second state, in which the slide frame 2-1 at least partially extends out of the accommodation space 1-3, and the foot rest plate 2-2 is located in front of the base body 1, facilitating support of the user's legs. The present utility model realizes function conversion by setting two states, and the foot rest plate 2-2 can be extended to the front of the base when needed, providing leg support in accordance with ergonomics. The partial extension design of the slide frame 2-1 ensures stability of support and avoids excessive space occupation.
[0035] The support leg 1-2 includes a front support leg 1-2-1 and a rear support leg 1-2-2, and the front support leg 1-2-1 and the rear support leg 1-2-2 have a side mounting plate 1-4 therebetween. The front support leg 1-2-1, the rear support leg 1-2-2 and the side mounting plate 1-4 form a stable support structure, enhancing the overall load-bearing capacity of the base.
[0036] The height of the front support leg 1-2-1 is greater than the height of the rear support leg 1-2-2, causing the seat portion 1-1 to be inclined from back to front. The design of the front-high rear-low support legs forms a naturally inclined seat surface, in accordance with the center of gravity distribution law when a person is in a sitting position, effectively preventing the user's body from sliding forward, and improving the comfort and safety of the sitting position.
[0037] The inclination angle of the seat portion 1-1 is 5-6 degrees. The inclination angle of 5-6 degrees has been verified by ergonomics, which can form a comfortable sitting angle and avoid the problem of difficulty in getting up due to excessive angle, achieving a balance between comfort and practicality.
[0038] In the first state, the baffle 2-3 blocks the front part of the accommodation space 1-3, and the side mounting plate 1-4 blocks the side of the accommodation space 1-3. The double blocking structure of the baffle 2-3 and the side mounting plate 1-4 forms a closed storage space, effectively preventing larger foreign matter from entering the accommodation space 1-3, while maintaining the visual integrity of the appearance of the base.
[0039] As shown in Figures 4-5 The slide frame 2-1 is provided with a mounting crossbar 2-4, and the mounting crossbar 2-4 is provided with the foot rest plate 2-2, facilitating position adjustment and maintenance and replacement of the foot rest plate 2-2.
[0040] The mounting crossbar 2-4 is a circular tube structure, a rotating piece 2-5 is rotatably connected to the mounting crossbar 2-4, and the foot supporting plate 2-2 is connected to the rotating piece 2-5, and the rotating connection realizes the multi-angle adjustment function of the foot supporting plate 2-2, and the support angle can be flexibly adjusted according to the body shape of the user and the use scene.
[0041] The rotating piece 2-5 is provided with a limiting groove 2-5-1, and the mounting crossbar 2-4 is provided with a limiting column 2-4-1 at a corresponding position, and the limiting column 2-4-1 is rotatably arranged relative to the limiting groove 2-5-1, so as to ensure that the rotating angle is within a safe range and avoid damage to the mechanism caused by excessive rotation.
[0042] In the first state, the limiting column 2-4-1 is rotated to the limit position relative to the limiting groove 2-5-1 and abuts against the end of the limiting groove 2-5-1, and the foot supporting plate 2-2 is in a horizontal state.
[0043] The front part of the sliding frame 2-1 is provided with a front crossbar 2-1-1, the surface of the front crossbar 2-1-1 is provided with a lower connecting plate 2-1-2, and the baffle 2-3 is connected to the lower connecting plate 2-1-2, so as to enhance the installation stability of the baffle 2-3, and the combination design of the front crossbar 2-1-1 and the lower connecting plate 2-1-2 can ensure the structural strength, realize the accurate positioning and quick disassembly of the baffle 2-3.
[0044] The lower part of the seat part 1-1 is provided with an anti-falling piece 1-5, and the sliding frame 2-1 is slidably connected to the circular hole of the anti-falling piece 1-5, so as to effectively prevent the sliding frame 2-1 from derailing, improve the service life of the product, maintain the smoothness of the sliding process, and ensure the reliability of the function conversion operation.
[0045] A chair with a hidden foot supporting function comprises a base with a hidden foot supporting function, a waist support and a head support.
[0046] The above is only a preferred embodiment of the present application, and the protection scope of the present application is subject to the scope defined by the claims, and some improvements and decorations made by those skilled in the art without departing from the spirit and scope of the present application should also be regarded as the protection scope of the present application.
