Description

[Detailed Description of the Invention] The present invention relates to a chair used in a so-called riding view port, which has a desk top plate attached to the front of a shelf so that it can be raised and lowered.

In general, Riding View has the advantage that the desk top can be stored in a raised state on the front of the shelf, so the space can be reduced when it is not used as a desk.

And the chair used for this riding view port is
Since this chair is stored in a space formed in a shelf at the bottom of the desk top, the seat height from the seat plate to the top of the backrest plate and the depth of the seat plate are the dimensions of the space, that is, from the floor surface. Since the height to the bottom of the desk top and the depth of the shelf are each limited, sufficient dimensions cannot be achieved, and in other words, the chairs that can be stored in the space become extremely small. This not only made it extremely difficult to sit, but also caused a feeling of fatigue.

The present invention is a chair that is stored in a shelf at the riding view port of this type, and is configured so that the backrest plate can be folded down onto the seat plate. By configuring the seat so that it extends forward when the chair stands up, the dimensions of the shelf are reduced when stored in the space, and the dimensions of the chair are enlarged when in use, allowing the chair to sit comfortably and without fatigue. It is.

Next, an example of the present invention will be explained with reference to the drawings. A drawer 4 linked to the desk top 3 is provided so that when the top 3 is flipped up and stored, it is pulled into the shelf 2, and when the desk top 3 is leveled, it comes out forward from inside the shelf. A sleeve drawer 5 and a space 6 for storing a chair 7, which will be described later, are provided below the desk top plate 3 on the shelf 2.

The chair 7 has a box-shaped main body 8 with casters 9 on the four corners of the lower surface.
It consists of a seat plate 10 and a backrest plate 11, with the left and right side plates 12.12' and the rear plate 13 of the main body 8 projecting upward, and the seat plate 10 being placed between the left and right side plates 12.12' on the upper surface of the main body 8 on a rail. 14 and 14' so as to be slidable back and forth, and brackets 18 and 18' that are parallel to the side surfaces and project upward are integrally fixed to both rear side surfaces of the seat plate 10, and both brackets 18.18 ' is a vertically long long slot 19
．． 19' is drilled.

Reference numeral 16.16' denotes a support link rotatably pivoted to a pin 15.15' on the inner surface of the rear part of the main body side plate 12.12' and appropriately above the long slot hole 19.19. The backrest plate 11 is integrally fixed to the upper end of the bracket 16', while a pin 17 and 17' provided at the lower end of the bracket 1B.

18' and are engaged with long slot holes 19 and 19', respectively.

In addition, when the backrest plate 11 is erected, it is supported by contacting the upper end of the rear plate 13 of the main body 8, and a backrest angle adjusting body 20 of the model is attached to the rear plate 13 so as to be vertically movable. 20 can be fixed at any position with a screw handle 21, a drawer 22 is provided inside the chair body 8, and a pull hole 23 is provided in the rear plate 13.

Since the present invention has the above-described configuration, when the backrest plate is tilted forward and rotated, the seat plate 10, which is engaged by the support links 16, 16' and the pins 17, 17' at the lower end of the backrest plate 11, When the chair 7 slides rearward and is automatically retracted in conjunction with the tilting rotation, and is tilted down until the backrest plate 11 touches the top surface of the seat plate 10, the height and front-to-back dimensions of the chair 7 are minimized. It is folded as shown by the two-dot chain line, and can be stored in the space 6 in the shelf 2 of the riding view port 1 in this state.

After taking the chair 7 out of the space of the shelf 2, if the backrest plate 11 is raised and rotated, the seat plate 10 will automatically slide forward in conjunction with this, and the backrest plate 11 will be raised up. At this time, the seat plate 10 protrudes to the maximum, and the depth dimension of the seat plate 10 increases.

As described above, according to the present invention, when the backrest plate of the chair is tilted forward, the seat plate is moved backward in conjunction with this, and the height and front-to-back dimensions are such that it can be stored in the space in the shelf of the riding view port. When the backrest plate is raised, the seat plate protrudes forward in conjunction with this, making it possible to increase the sitting height and seat depth when using the chair, while still being able to store it inside a shelf, making it comfortable. It is more comfortable and causes less fatigue, and the chair of the present invention can be made smaller when stored, so it can be equipped with sleeve drawers as shown in the figure.
The Riding View Kawako, which has a drawer linked to the desk top on the underside of the desk top, can also be applied, and since the backrest and seat boards are linked, it has the effect of allowing the chair to be stored and used quickly. .
