Description

Technical Field

[0001] The utility model relates to an office supply, especially a footrest used in an office. Background Art

[0002] As we know, office workers sit on office chairs for a long time to work, making their legs in a tense state for a long time. In this way, over time, their legs and feet are prone to occupational diseases such as varicose veins. To relieve the long-term discomfort of the legs and feet, people have invented office footrests. Currently, there are mainly the following three types of office footrests, and they all have certain deficiencies:

[0003] One is a retractable footrest installed under the office chair. For example, a footrest structure for an office chair with the patent publication number CN218738050U. It is mainly pulled out to support the feet during the lunch break and is not suitable for supporting the feet during work.

[0004] One is installed and fixed on the support plate of the desk. For example, a folding footrest structure for a desk with the patent publication number CN217959183U. Since it is used by being installed on the column of the desk, it is not very convenient to use during use, and the position for supporting the feet is restricted to a certain extent. Therefore, the user cannot fully adjust to a suitable position to place the feet according to their own needs;

[0005] Another one is a mobile type. For example, a multi-purpose office footrest with the patent publication number CN208017244U. It has the characteristics of being convenient to carry and store. However, during use, one hand needs to swing to open the rotating base plate, and the other hand needs to swing the support plate to support on the back of the rotating base plate. In this way, it is not very convenient to use. Moreover, the opening angle of the rotating base plate cannot be adjusted. Therefore, the user cannot fully adjust to a suitable foot-supporting angle according to their own needs.

[0006] In view of the various deficiencies of the above-mentioned footrests, the applicant has improved the office footrest. Summary of the Invention

[0007] The purpose of the utility model is to provide an office footrest with a reasonable structure, convenient to use and store, and capable of being placed at a suitable position and adjusted to a suitable foot-supporting angle according to needs.

[0008] To solve the above-mentioned existing technical problems, the utility model adopts the following technical solutions:

[0009] An office footrest includes a footrest frame, a pedal, and a pedal opening and closing structure, wherein:

[0010] The footrest frame is annular;

[0011] The lower part of the pedal is swingably connected to the footrest frame;

[0012] The pedal opening and closing structure includes a swing box, a telescopic plate, an opening angle locking component, and a locking member highest position unlocking and returning structure; one end of the swing box is swingably connected to the pedal, and the other end is provided with an inlet and outlet for the telescopic plate; one end of the telescopic plate is swingably connected to the middle of the pedal, and the other end can telescopically enter and exit the inlet and outlet of the telescopic plate of the swing box; when the pedal swings open by an angle, it is positioned by the opening angle locking component, and when the pedal is opened to the maximum angle, after the opening angle locking component is unlocked by the locking member highest position unlocking and returning structure, the pedal automatically swings and closes under the action of its own gravity.

[0013] In the improvement scheme of the above office footrest, the opening angle locking component includes an opening angle gear group arranged in the swing box, a locking tooth swingably connected to the telescopic plate through a pin, and a locking tooth return spring that can swing the locking tooth towards the opening angle gear group and engage with a corresponding part of the gear teeth.

[0014] In the improvement scheme of the above office footrest, the tooth profiles of the opening angle gear group and the locking tooth are right-angled surfaces on the engaging surface and inclined surfaces on the other surface.

[0015] In the improvement scheme of the above office footrest, the locking member highest position unlocking and returning structure includes an unlocking force receiving post arranged on the locking tooth, a pin strip-shaped groove and a force receiving post accommodating groove arranged on the telescopic plate; after the two ends of the pin are arranged in the pin strip-shaped groove, it can rotate and slide in the groove; the column action surface of the force receiving post accommodating groove is a thrust inclined surface; the unlocking force receiving post can slide along the thrust inclined surface and enter and exit the force receiving post accommodating groove.

[0016] In the improvement scheme of the above office footrest, support foot positions are provided at the corners of the bottom surface of the footrest frame.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the lower part of the pedal is swing-connected to the footrest, and a pedal opening and closing structure is provided between the middle part and the other side of the footrest, and the pedal opening and closing structure includes a swing box, a telescopic plate, an opening angle locking component, and a locking member highest position unlocking and returning structure. In this way, when a hand acts on the side of the pedal away from the swing end and is lifted upward and outward, the pedal can be slowly swung open, and each time the pedal is swung open by an angle, it is positioned by the opening angle locking component. In this way, office workers can adjust the opening angle of the pedal according to their own needs; when the pedal is opened to the maximum angle, the opening angle locking component is unlocked by the locking member highest position unlocking and returning structure, and the swing box and the telescopic plate release the inclined support for the pedal. Then, under the action of its own gravity, the pedal automatically swings and closes towards the direction of the footrest. In this way, the opening, closing and storage of the footrest can be realized with one hand. Therefore, the structure of the present utility model is reasonable, the operations of opening, using and storing are convenient, and it can be placed at a suitable position and adjusted to a suitable foot-bearing angle according to needs.

[0024] Figure 6 is Figure 5 an enlarged view of the partial I. Specific Embodiments

[0025] An office footrest, as Figures 1 to 6 shown, includes a footrest 1, a pedal 2, and a pedal opening and closing structure 3, wherein:

[0026] The footrest 1 is annular, and it can be square, rectangular, oval, etc.; the weight of the footrest is usually heavier than that of the pedal;

[0027] The lower part of the pedal 2 is swingably connected to the pedal frame 1. In this embodiment, since the pedal frame is square, at this time, it is swingably connected to a horizontal side.

[0028] The pedal opening and closing structure 3 includes a swing box 31, a telescopic plate 32, an opening angle locking component 33, and a locking member highest position unlocking and returning structure 34. One end of the swing box 31 is swingably connected to the pedal (here, connected to the other horizontal side of the pedal frame), and the other end is provided with a telescopic plate inlet and outlet 311. One end of the telescopic plate 32 is swingably connected to the middle of the pedal 2, and the other end can telescopically enter and exit the telescopic plate inlet and outlet 311 of the swing box 31. Each time the pedal 2 swings open an angle, it is positioned by the opening angle locking component 33. When the pedal is opened to the maximum angle, after the opening angle locking component 33 is unlocked by the locking member highest position unlocking and returning structure 34, the pedal 2 automatically swings and closes under the action of its own gravity.

[0029] As can be seen from the above, since the lower part of the pedal 2 is swingably connected to the pedal frame 1, and a pedal opening and closing structure 3 is provided between the middle part and the other side of the pedal frame 1, and the pedal opening and closing structure 3 includes a swing box 31, a telescopic plate 32, an opening angle locking component 33, and a locking member highest position unlocking and returning structure 34. In this way, when a hand acts on the side of the pedal 2 away from the swing end and pulls it upward and outward, the pedal 2 can be slowly swung open, and each time the pedal 2 swings open an angle, it is positioned by the opening angle locking component 33. In this way, office staff can adjust the opening angle of the pedal according to their own needs. When the pedal 2 is opened to the maximum angle, after the opening angle locking component 33 is unlocked by the locking member highest position unlocking and returning structure 34, the swing box 31 and the telescopic plate 32 release the inclined support for the pedal 2. Then, the pedal 2 automatically swings and closes in the direction of the pedal frame 1 under the action of its own gravity, realizing the closing and storage of the footrest. Therefore, the structure of the present utility model is reasonable, the operations of opening, using and storing are convenient, and it can be placed at a suitable position and adjusted to a suitable footrest angle according to needs.

[0030] In this embodiment, as Figures 1 to 6 shown, the opening angle locking component 33 includes an opening angle gear group 331 provided in the swing box 31, a locking tooth 333 swingably connected to the telescopic plate 32 through a shaft pin 332, and a locking tooth return spring 334 that can swing the locking tooth 333 towards the opening angle gear group 331 and engage with a corresponding part of the gear teeth. Preferably, the tooth shapes of the opening angle gear group 331 and the locking tooth 333 are right-angled surfaces on the engagement surface and inclined surfaces on the other surface.

[0031] The highest-bit unlocking and returning structure 34 of the locking member includes an unlocking force-bearing post 341 provided on the locking tooth 333, a pin strip-shaped groove 342 and a force-bearing post accommodating groove 343 provided on the telescopic plate 32; after both ends of the pin 332 are provided in the pin strip-shaped groove 342, it can rotate and slide in the groove; the column acting surface 3431 of the force-bearing post accommodating groove 343 is a thrust inclined surface; the unlocking force-bearing post 341 can slide along the thrust inclined surface 3431 and then enter and exit the force-bearing post accommodating groove 343; during the process of opening the pedal 2, the unlocking force-bearing post 341 on the locking tooth 333 is always located in the force-bearing post accommodating groove 343 of the telescopic plate 32. When the pedal 2 is opened a little more from the highest gear position ( Figure 2 shown), since there is no higher opening angle gear position tooth in the swing box 31 for the locking tooth 333 to slide down, at this time, the thrust inclined surface of the force-bearing post accommodating groove 343 acts on the unlocking force-bearing post 341 of the locking tooth 333, so that after the locking tooth 333 overcomes the acting force of the locking tooth return spring 334, while the pin 332 slides along the pin strip-shaped groove 342, the locking tooth 333 swings around the pin 332 and leaves the opening angle gear position tooth group 331, as Figure 3 shown. In this way, after the locking tooth 333 and the opening angle gear position tooth group 331 are disengaged, the locking tooth 333 can slide a small distance inward in the swing box 31 to reset; when it touches the touch position 312 at the inner end of the swing box 31, as Figures 4 to 6 shown, the locking tooth 333 can be returned to engage with the opening angle gear position tooth group 331 in the swing box 31, as Figure 1 shown. In this way, one operation process of opening and closing the footrest is completed.

[0032] Preferably, a support foot position 11 is provided at the corner of the bottom surface of the footrest frame 1, which can avoid scratching the footrest frame and the ground.

[0033] In this embodiment, as Figure 5 shown, the swing box 31 is composed of upper and lower halves, and they can swing around the footrest pedal when clamped outside the footrest frame 1.
