The position of the arm 3 from front to back toward the sitting board 1 is adjusted corresponding to the length of thigh part of the sitting person, and the arm 3 is fixed onto the seat board 1. Besides, the rod 7 is elongated/contracted corresponding to the length of leg under the knee of the sitting person, the gap between the sitting plane of the sitting board 1 and the upper face of the foot rest 16 is adjusted, and the elongation/contraction of the rod 7 is locked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair with a footrest.

[0002]

2. Description of the Related Art Conventionally, as a chair used for drawing work or the like, as shown in FIG. 5, a supporting leg 51 extending radially from the lower end of a pedestal 50 is attached to a footrest ring 5.
It is known that 2 is attached.

However, in the chair as described above, the height of the ring 52 cannot be adjusted. Therefore, when the height of the seat plate is adjusted according to the height of the drawing board or the like, depending on the physical constitution of the seated person. Sometimes, it was difficult to reach the ring 52 or the knee felt cramped.

Further, since the ring 52 is formed of a pipe, there is a problem that the foot is slippery when shoes are not worn.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention
An object of the present invention is to provide a chair with a footrest that allows seated persons of various physiques to comfortably and stably rest their legs.

[0006]

In order to solve the above-mentioned problems, according to the present invention, an arm extending in the front-back direction is provided slidably in the axial direction on the back surface of a seat plate, and extends downward at the front end of the arm. Adopting a structure in which a retractable rod is continuously provided, a footrest made of a plate is attached to the lower part of the rod, means for fixing the arm to the seat plate, and means for locking the expansion / contraction of the rod are adopted. .

In the above-mentioned chair, when sitting, the arm is slid in the front-back direction, the front-back position of the footrest with respect to the seat plate is adjusted according to the length of the thigh of the seated person, and the arm is fixed to the seat plate. Then, the rod is expanded and contracted according to the length below the knees of the seated person, the distance between the seat surface of the seat plate and the upper surface of the footrest is adjusted, and the expansion and contraction of the rod is locked.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 3, a pair of guide members 2 are attached to the back surface of the seat plate 1, and each guide member 2 has an arm 3 extending in the front-rear direction.
Are supported slidably in the axial direction. Each arm 3
Is provided with a plurality of screw holes 4 at required intervals in the axial direction, and a fixing screw 6 can be screwed into one of the screw holes 4 via an insertion hole 5 formed in the guide member 2. Thus, each arm 3 is fixed to the seat plate 1.

A rod 7 extending downward is connected to the front end of each arm 3. The rod 7 has a structure in which an inner pipe 9 is slidably inserted into an outer pipe 8. The inner pipe 9 is provided with a plurality of screw holes 10 at required intervals in the axial direction, and a fixing screw 12 is inserted into one of the screw holes 10 through an insertion hole 11 formed in the outer pipe 8. The expansion and contraction of the rod 7 is locked by screwing. The rear ends of both arms 3 are connected via a pipe 13 extending in the left-right direction.

A pipe 14 extending forward is connected to the lower end of each rod 7, and the front ends of the pipes 14 are connected by a pipe 15 extending in the left-right direction. Pipe 14,
A footrest 16 made of a plate is placed on 15
The footrest 16 is attached to the pipe 14 and 1 by screws 17.
5 is fixed.

In the chair as described above, each arm 3 is slid in the front-rear direction, the position of the footrest 16 with respect to the seat plate 1 in the front-rear direction is adjusted according to the length of the thigh of the seated person, and the screw holes 4 and The insertion holes 5 are aligned and the fixing screws 6 are screwed into the screw holes 4. Then, the rod 7 is expanded and contracted according to the length below the knees of the seated person, and the seat surface of the seat plate 1 and the footrest 1 are
6 is adjusted, the screw hole 10 and the insertion hole 11 are aligned, and the fixing screw 12 is screwed into the screw hole 10.

After adjusting the position of the footrest 16 as described above, even if the height of the seat plate 1 is changed as shown in FIG. 4, the relative positional relationship between the seat plate 1 and the footrest 16 is maintained. Therefore, it is not necessary to readjust the position of the footrest 16.

In addition to the office chair shown in the figure, a baby chair that faces the dining table may be constructed as described above. In this case, since the position of the footrest 16 can be adjusted as the infant grows, it can be used for a long period of time.

[0014]

[Effects] According to the present invention, since the structure is as described above, by sliding the arm in the front-back direction, the position of the footrest in the front-back direction can be adjusted according to the length of the thigh of the seated person. Further, by expanding and contracting the rod, the vertical position of the footrest with respect to the seat surface can be adjusted according to the length of the seated person's knees.

Therefore, seated persons of various physiques can comfortably rest their feet on the footrests.

Further, even if the height of the seat plate is changed after the position of the footrest is adjusted, the relative positional relationship between the seat plate and the footrest is maintained, so that it is not necessary to readjust the position of the footrest. .

In addition, since the footrest is made of a plate, it is possible to stably hang the foot even when shoes are not worn.
