Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair with a footrest, and an object of the present invention is to provide a chair with a footrest in a simple and rational configuration so that the footrest is arranged in front of the seat and connected to the seat as necessary. This invention relates to a chair with a footrest that can be completely stored under the seat when not needed.

When sitting in a chair in a relaxed state, it is easier to raise your feet to the same height as the seat than to sit with your feet on the floor, even though it may be considered bad manners. For this reason, there have been various types of chairs with footrests, but in conventional chairs with footrests, the footrests are stored at the bottom of the front of the seat, so no matter how much effort is made to store them, the footrests cannot be made larger. It felt like it was an accessory.

It also had a bad image as a chair, as it did not have the effect of lowering foot comfort. Furthermore, in the retracted state, the I11/I cannot be fully increased, and if you sit with your legs bent at a right angle, your calves, heels, etc. will touch the exposed footrest, making it extremely difficult to maintain an ideal posture. It had the disadvantage of leprosy.

Therefore, the present invention makes effective use of the space under the seat as a storage area for the footrest and ensures that the footrest itself is large enough, while at the same time ensuring that the footrest is completely retracted and not exposed when it is stored. The present invention provides a chair with a footrest that has a sufficient foot rest effect and functional beauty when in use.The structure is such that a slide rail is provided on the back side of the seat in the front-rear direction, and a slide rail is provided on the back side of the seat in the front-rear direction. By combining a slidable sliding body, pivoting one end of a connecting member to the sliding body, and pivotally supporting the other end of the connecting member to the rear end of a footrest that can be stored in a space under the seat. A sliding body and a footrest are connected, and the footrest is movable between the bottom of the seat and the front of the seat within the sliding range of the sliding body, and both ends of the connecting member are pivoted when pulled out forward. The rear end portion of the footrest is formed to be able to be lifted upward when the footrest rotates, and a fixing mechanism is provided at the pivot point between the sliding body and the connecting member.

Next, in order to concretely explain the configuration and effects of the present invention, examples of the present invention will be explained based on the drawings as follows.

In FIG. 1, slide rails 2.2 having a C-shaped cross section are disposed on both sides of the back side of the seat 1 in the front-rear direction, and a sliding body 3.3 having a T-shaped cross section is disposed on the slide rail 2.2. A connecting rod 4.4 is rotatably supported on the sliding body 3.3. Since both sides of the back side of the seat 1 have the same structure, only one side will be described below. The sliding body 3 can freely move within the slide rail 2, and mounting plates 2a, 2a are protruded from the lower part. On the other hand, a connecting member 4a having a U-shaped cross section is attached to one end of the connecting rod 4, and the connecting member 4a, which is made of a U-shaped vibrator, is attached to one end of the connecting rod 4 between the plates 2a, 2a. 4a is the pivot pin 4b
The above installation is on board 2a, iJ! Plate 2 is attached to the connecting column member 4a.
The connecting rod 4 is rotatably supported by passing through the connecting rods in the order of a. One of the pivot parts is provided with a fixing mechanism that fixes the connecting rod 4 in a predetermined posture, and the fixing mechanism includes:
For installation, one side of the plate 2a is extended downward, an insertion hole 5a is bored in the extended portion 2°a, and an insertion hole 6 is formed on the outer surface of the plate 2a.
A hollow pyramid-shaped bracket 6 with a hole a is attached,
The lock pin 7 is inserted through the re-insertion holes 5a and 6a.

An inward biasing force is applied to the lock pin 7 within the bracket 6 by a pin 5b and a spring 5c, and an IF hole (described later) is bored on the side of the connecting rod 4 in the direction of the biasing force. By inserting the lock pin 7 into the fixing hole, the pivot portion can be fixed. 8 is a footrest, and the footrest 8 includes a brushbon part 8a.
A mounting bracket 9 is provided with a leg 8b protruding from the front lower side of the frame and two mounting plates 9a and 9b projecting downward from the rear lower side.
is installed. The other end of the aforementioned connecting rod 4 is rotatably supported on the mounting bracket 9 by a pivot pin 4'b via a connecting member 4°a attached to the other end of the connecting rod 4. The footrest 8 can be stored in the space under the seat while being connected via the sliding body 3 and the connecting rod 4. The pivot points between the sliding body 3 and the connecting rod 4 include: - On the side of the connecting rod 4, there is a footrest attached to the lock bin tip abutment area in the rest storage position and in the state where the footrest is pulled out and the rear end is raised. Holes 10 and 11 are drilled so that the footrest can be pulled out forward while fixed in the stored position, or it can be fixed with the footrest pulled out and its rear end raised. can. To release the fixation, pull the lock pin 7 outward to remove it from the fixed hole 10 (or 11) into which the lock pin 7 is inserted, and rotate the connecting rod to remove the lock pin 7 and the fixing hole 10. (or 11) may be shifted. When the lock pin 7 is released, the tip of the lock pin 7 moves while being pressed against the guide plate 12 fixed between the fixing holes 10 and 11 by the spring force, and during this period, the lock pin 7 moves while being pressed against the guide plate 12 fixed between the fixing holes 10 and 11. Becomes in a state of freedom of movement. The reinforcing vibrator 13 installed between the connecting rods 4 and 4 in the drawing firmly connects the left and right connecting rods, moves them together, and prevents the footrest from collapsing when the footrest is taken in and out. are doing.

Each phase branch has a connecting member 4 with a U-shaped cross section at the end of the connecting rod.
It is also possible to pivot without attaching a and 4'a, but in that case it is necessary to provide another fixing mechanism to the pivot.

The chair with a footrest configured as described above can be stored in the space under the seat when the footrest is unnecessary. In that case, the footrest can be completely stored deep under the seat, so even if you sit with your legs bent at right angles, your calves and heels will not come into contact with the footrest, and you can use it just like a regular chair. When using the footrest, pull the footrest forward from under the seat, remove the lock pin from one of the fixing holes, and then pull the footrest to lift the rear end of the footrest and connect the footrest to the front of the seat. When the lock pin is in the closed state, the other fixing hole matches the position of the lock pin, and the tip of the lock pin is inserted into the other fixing hole by the force of the spring, thereby fixing the sliding body and the connecting rod. Thereby, the footrest is supported by the front legs and the rear connecting rod and set in a fixed position.

In the chair with a 7-piece rest of the present invention, when the footrest is pulled out forward, the sliding body moves along the slide rail and the legs slide on the floor surface, so that the footrest can be pulled out smoothly. Also, when the rear end of the outrest is lifted up by being pulled out, the connecting rod connecting the seat and footrest rotates, and the movement continues in a continuous sequence until the footrest is set in place. Because of the movement, it doesn't feel unnatural, as if the two were integrated.

In the chair with a footrest of this embodiment, since the connecting rod as a connecting member is formed in a U-shape, it matches the movement of the footrest and makes an arcuate movement when rotating, giving it functional beauty.

In the present invention, the slide rail and the sliding body are a combination in which the sliding body can move in the sliding direction, so that the sliding body is not only fitted into the rail but also fitted outside the slide rail or attached to the wheel. It can also be attached to ensure smooth movement. Further, the connecting member is not limited to a U-shape unless a design effect is expected by covering the bottom of the seat so that the connecting member is not visible.

By using a link with an appropriate fixing mechanism or by using a plate pivoted by a hinge member that exerts a snap force on both bent sides, the rear end of the footrest is configured to fly up due to the snap force when the footrest is pulled out. However, the fixing mechanism is not limited to the mechanism shown in the above embodiment depending on the structure of the pivot portion.

As described above, in the chair with a footrest of the present invention, the footrest is completely stored under the seat, and can be easily set in a continuous manner in front of the seat if necessary. Moreover, since the large space under the seat is used as a storage area, the footrest can be made larger, and when set in front of the seat, it provides a sense of unity and is superior in terms of design. In addition, since it is possible to take an ergonomically optimal posture depending on the purpose of use, the effect is tremendous in combination with aesthetics and ease of operation.
