Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a pedal device and a seat. Background Art

[0002] The seats on the market are usually equipped with a footrest device that can slide forward and backward. This footrest device is also called a footrest device, which is usually composed of a slide rail, a rotating shaft seat, and a pedal, wherein the slide rail is slidably connected to the bottom of the seat, the rotating shaft seat is connected to the front end of the slide rail, and the pedals are symmetrically arranged on both sides of the rotating shaft seat and form a rotating connection with the rotating shaft seat; when the footrest device is opened, the slide plate slides forward, the pedal flips forward and supports the legs; when the footrest device is retracted, the slide plate slides back, the pedal flips backward, and is folded under the seat.

[0003] For example, in the pedal device patent with announcement number CN218635651, the pedal device includes a guide rod and a rotating shaft seat body. A rotating shaft tube is integrally formed at the front end of the rotating shaft seat body, and the pedal is rotatably connected to the rotating shaft tube; a slot is provided at the rear end of the rotating shaft seat body, and the front end of the guide rod is horizontally inserted into the slot and remains relatively fixed.

[0004] Among them, in order to prevent the shaft cylinder and the pedal from interfering or colliding with the front end of the seat after the seat is retracted, the shaft cylinder is arranged at the lower position of the shaft seat body, the upper end surface of the shaft seat body extends horizontally to be connected to the shaft cylinder, and the lower end of the rotating seat body extends obliquely downward, so that the shaft cylinder and the pedal are always under the seat after the seat is retracted; but the shaft seat body protrudes outward from the shaft cylinder, affecting the aesthetics of the entire foot pedal device; when the shaft seat is mass-produced, the existence of the shaft seat body will also increase the cost of the foot pedal device. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise clearly defined. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0036] The specific implementation methods of the utility model are as follows:

[0037] like Figure 1-9 As shown, this embodiment provides a footrest device, including a footrest assembly and a slide rail 1, the front end of the slide rail 1 extends obliquely downward, and a connecting portion 11 is integrally formed at the front end of the slide rail 1; the footrest assembly includes a support seat 3 and pedals 2 rotatably connected to the left and right ends of the support seat 3, and the pedals 2 can be opened forward or retracted backward by rotating themselves; a slot 32 opening toward the connecting portion 11 is provided on the support seat 3; the connecting portion 11 is inserted into the slot 32 along the opening and fixedly connected to the support seat 3.

[0038] Further, if Figure 3 As shown, the pedal 2 is mainly used to support the legs of the human body, so a plurality of inwardly recessed anti-skid grooves 22 are provided on the upper surface of the pedal 2. When the legs are placed on the upper surface of the pedal 2, the inwardly recessed anti-skid grooves 22 will generate greater friction with the legs to prevent the legs from slipping on the pedal 2.

[0039] Furthermore, the support seat 3 is cylindrical, and a through hole 36 penetrating the slot 32 is provided on the outer wall of the support seat 3, and a screw hole 12 is provided on the connecting portion 11. A screw (not shown) passes through the through hole 36 and is screwed into the screw hole 12 to fix the support seat 3 and the connecting portion 11 in connection; the screw connection method is stable and reliable, and can ensure the fixing effect of the slide rail 1 and the support seat 3; in order to ensure the simple appearance of the pedal device, a first countersunk hole 35 for accommodating the screw head is provided on the support seat 3, and the first countersunk hole 35 is concentric with the through hole 36; the first countersunk hole 35 can provide an accommodating space for the screw head to avoid affecting the appearance of the support seat 3 due to the exposure of the screw head.

[0040] Further, if Figure 4 As shown, the through hole 36, the first countersunk hole 35, and the screw hole 12 are all configured in three, and the through hole 36, the first countersunk hole 35, and the screw hole 12 are all arranged in a triangular shape. The triangular arrangement can make the fixed connection between the slide rail 1 and the support seat 3 more stable, and avoid the positional displacement of the support seat 3 at the connection portion 11.

[0041] Further, if Figure 3-7b As shown, after the slide rail 1 is directly plugged into the support seat 3, the installation space on the support seat 3 is occupied. Therefore, in order to enable the pedal 2 to be normally opened forward or retracted backward, the left and right ends of the support seat 3 are provided with outwardly protruding protrusions 34, and the protrusion 34 includes a limiting block 33 integrally formed therewith; the pedal 2 is provided with a receiving groove 23 for accommodating the protrusion 34, and the receiving groove 23 is provided with a rotating block 21 extending inward along the inner wall of the receiving groove 23; when the pedal 2 rotates forward and backward, the rotating block 21 will rotate circumferentially relative to the protrusion 34 and the limiting block 33, and the receiving groove 23 can provide space for the relative rotation of the protrusion 34 and the limiting block 33; when the pedal 2 is in the open state or the retracted state, the limiting block 33 abuts against the rotating block 21 to limit the pedal 2 from continuing to rotate; the limiting block 33 cooperates with the rotating block 21 to keep the pedal 2 stable when opened or retracted, thereby ensuring the normal use effect of the pedal 2.

[0042] Further, if Figure 2 As shown, in order to enable the pedal 2 to rotate stably relative to the support seat 3, a rotating shaft bolt 4 is provided between the pedal 2 and the support seat 3 to provide support for the rotation of the pedal 2; a threaded hole 31 is provided on the protrusion 34, and an avoidance hole 24 is provided on the pedal 2 to pass through in the left and right directions. In order to ensure the simple appearance of the pedal device, a second countersunk hole 25 concentric with the avoidance hole 24 is provided at the outer end of the pedal 2, and the second countersunk hole 25 can be used to accommodate the head of the rotating shaft bolt 4; the rotating shaft bolt 4 passes through the avoidance hole 24 and is screwed into the threaded hole 31, so that a rotating connection is formed between the pedal 2 and the support seat 3; the cooperation between the rotating shaft bolt 4 and the threaded hole 31 is simple and efficient, thereby providing rotation support for the pedal 2.

[0043] Furthermore, in order to facilitate installation, a nut (not shown) is embedded in the protrusion 34, and the threaded hole 31 is set on the nut; the embedded nut can make it unnecessary to re-drill the shaft bolt 4 during installation, thereby improving the assembly efficiency between the pedal 2 and the support seat 3.

[0044] Further, if Figure 8 As shown, in order to prevent the pedal 2 from causing rotational wear with the thread of the shaft bolt 4 as much as possible when the pedal 2 rotates, the shaft bolt 4 is configured as a semi-threaded bolt, including a threaded section 42 at its tail end and a shaft section 41 adjacent to the threaded section 42, and no thread is provided on the shaft section 41; the shaft section 41 is located in the avoidance hole 24, and the threaded section 42 is located in the threaded hole 31; the threaded section 42 can ensure the rotational connection effect between the pedal 2 and the support seat 3, and the shaft section 41 can prevent the pedal 2 from causing friction between the inner wall of the avoidance hole 24 and the thread when the pedal 2 rotates back and forth, thereby ensuring the structural strength of the pedal 2 and improving the service life of the pedal 2.

[0045] Further, if Figure 5 As shown, in order to ensure the structural strength of the pedal device, the slide rail 1 is a metal part, and the connecting portion 11 is formed by bending the front end of the slide rail 1 downward; the bending process is simple and efficient, and the connecting portion 11 of the slide rail 1 can be formed obliquely downward along a predetermined path; considering the actual situation when the pedal 2 is used, the downward bending angle range of the connecting portion 11 is 15°-45°.

[0046] like Figure 1 As shown, a seat is provided, including a seat 5 and a foot pedal device, which is connected to the lower end of the seat 5 by sliding along the front-to-back direction through a slide rail 1; when the foot pedal device slides back to the lower end of the seat 5, the installation connection position of the support seat 3 and the slide rail 1 has a simple structure and a simple appearance, so that the foot pedal device will not interfere with the seat 5 when retracted.

[0047] Further, if Fig. 9 As shown, in order to limit the sliding support seat 3, a limiting buffer portion 51 is provided at the lower end of the seat 5, and an arc-shaped abutting surface is provided at the front end of the limiting buffer portion 51. When the slide rail 1 drives the support seat 3 to slide back to the bottom of the seat 5, the abutting surface abuts against the outer wall of the support seat 3 to form a buffer for the entire footrest device.

[0048] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
