Description

Folding footrest chair {AAAAA}

The present invention relates to a folding footrest chair having a footrest capable of supporting a user's foot at a predetermined height, and more particularly to a folding footrest chair having a footrest extended or folded according to the back state of the backplate. will be.

In general, the chair is provided with a footrest according to its purpose to keep the user's foot in a comfortable state.

In other words, commercial barber chairs, armchairs used for office and home use has a footrest, so that the angle of the knee and foot in the state of leaning on the back by the user put the foot on the footrest to the optimal state.

However, the footrest applied to the conventional chair is always located under the front of the chair in a fixed state, so that it is applied only to the chair having a certain seat.

In other words, when the height of the low back chair maintains the general angle, the foot is placed on the floor in an optimal state, or the height adjustment device of the chair is applied so that the height can be shared to other users.

Therefore, the footrest applied to the conventional chair has a structurally difficult problem to support or not to support the foot according to the back state lying down.

The present invention is devised to solve the above problems, the object of the present invention is to maintain the extended state that the foot can be raised in the state where the back plate is lying down without interfering with the foot in the state where the back plate is returned It is to provide a folding footrest chair for maintaining a folded state.

The technical idea of the present invention for achieving the above object is provided with an operating means for operating forward and backward in accordance with the lying state of the back plate on both sides of the seat having a seat plate and the back plate on which the seat is placed, the auxiliary foot and By connecting the folding means having the scaffold, the scaffold is extended when the back plate is laid down, and the scaffold is folded when the back plate is restored.

Hereinafter, with reference to Figures 1 and 2 attached to an embodiment of the present invention in detail as follows.

In the figure, reference numeral 100 denotes the entire chair according to the present invention, and the chair 100 has a seat plate 4 on which the seat 6 is placed and a back plate 2 supporting the back, and on both sides of the seat plate 4. It is connected to the fixed frame 10 is fixed to provide a configuration of the operation means for operating forward and backward according to the lying state of the back plate (2), and the folding means connected to the operating means and folded.

The operating means is a support 20 that is rotated in accordance with the back state of the back plate 2 is supported on the back plate 2 in a state that is freely coupled to the fixed frame 10, the support plate 20 at a predetermined interval The first pivot 21 and the second pivot 22, the first pivot 21 and the second pivot 22 and the support 20 are coupled to the fixed frame 10 so as to rotate freely. It is composed of a first connecting rod 23 and a second connecting rod 24 which are sequentially connected to be freely rotated to operate back and forth according to the lying state of the back plate 2.

And the folding means is a pair of first folding stand 30 and the second folding stand 31, the first folding stand that is freely connected to the rotation frame from the fixed frame 10 and the second pivoting table 22 of the operating means Auxiliary scaffold 50, which is freely rotatably connected alternately from the 30 and the second folding stand 31, scaffold 40 is freely connected to the auxiliary scaffold 50, the scaffold 40 and the fourth fold Stool folding table (34), which is freely connected to the rotation 33, and the scaffold folding table (34) and the auxiliary scaffold folding table (35) to be freely connected to the auxiliary scaffold (50).

In addition, the coupling for free rotation of the folding means and the operating means is connected to the hinge between the members, but the reference to this is omitted entirely.

Referring to the operation of the present invention to the above configuration is as follows.

1 is a state in which the footrest 40 applied to the chair 100 of the present invention is folded.

When the back plate 2 is laid down as shown in FIG. 2, the support 20 supporting the back plate 2 is also laid down with the back plate 2 according to the load of the back plate 2.

Accordingly, while the first connecting rod 23 and the second connecting rod 24 are pushed by the support 20, the first side of the first belt 211 and the second side of the pivot 22 are fixed to the fixed frame 10. The chair 100 rotates to the front side at an angle.

Accordingly, the folded first folding stand 30 and the third folding stand 32 are extended while pushing the second folding stand 31 and the fourth folding stand 33. At this time, the auxiliary connected to the third folding stand 32 The footrest 50 is exposed to the front of the chair 100. In addition, the scaffold folding stand 34 connected to the fourth folding stand 33 is extended while pushing the auxiliary scaffold folding stand 35 so that the scaffold 40 and the auxiliary scaffold 50 are horizontally lowered in front of the chair 100. In this situation, the user can put his foot on the footrest 40 and the auxiliary footrest 50 while supporting the back of the back plate 2.

On the other hand, when the back plate 2 is erected in the state of FIG. 2, the footrest 40 and the auxiliary footrest 50 are folded into the state of FIG. 1 by the reverse order.

The present invention provides the comfort of supporting the user's feet in a horizontal state by exposing the footrest to the front of the chair in a state where the backside is laid, and the footrest is placed on the bottom of the chair while the backrest is placed so that the foot of the user is placed. By not interfering, the user has the effect of providing the optimal state of the foot of the foot depending on the state of the back for resting and working.
