JPS581264Y2 - Chair - Google Patents

Description

[Detailed explanation of the invention] Most of the chairs and banquettes currently installed in the stands of stadiums, etc. have a seat plate and a back plate fixedly attached. Because the surface of the floor is always exposed, there is rainwater on the floor after it rains, and you cannot sit on it unless you wipe it off.

Furthermore, even on sunny days, dust would adhere to the seating surface, which could stain clothes, making it difficult to sit comfortably.

Some commonly known chairs have a seat plate that rotates upwards, but since there is a vertical gap between the back plate and the seat plate, rainwater and dust can enter through this gap and cause the back plate to stand up. And the seat board will get dirty.

Therefore, the present invention has a structure in which the back plate is automatically placed over the seat plate when not in use to prevent the seating surfaces of the back plate and the seat plate from getting wet with rain or getting dirty with dust, so you can rest assured that your clothes will not get dirty at any time. The idea is to provide a bench on which people can sit.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 show a chaise longue, in which the lower edge 5 of a back plate 4 is formed to have approximately the same shape and dimensions as the seat plate 1 in relation to the connecting piece 3 of the rear edge 2 of the seat plate 1. The connecting piece 6 is pivotally attached by a pivot shaft 7, and the back plate 4 is configured to be rotatable in the front and rear directions with respect to the seat plate 1.

As shown in FIG. 3, the connecting piece 6 of the back plate 4 is provided with a spacing 9 that comes into contact with the rear edge 8 of the connecting piece 3 of the seat plate 1, so that the back plate 4 is moved rearward from the upright position. It is configured so that it does not rotate.

The back plate 4 is formed of a waterproof synthetic resin plate, and its back surface is reinforced with a rectangular frame 11 made of metal pipe.

The seat plate 1 is made of a waterproof synthetic resin plate, and is fixed to the upper surface of a base 10 made of metal pipe.

A weight 13 is provided at the tip of the armrest 12 of the back plate 4 as a biasing means for rotating the back plate 4 in the forward direction, and the center of gravity 0 of the back plate 4 is positioned forward of the upper position of the pivot shaft 7. I'm letting you do it.

Therefore, the back plate 4 is normally held in a position where it closely overlaps the upper surface of the seat plate 1, as shown in FIG.

When in use, the user manually rotates the back plate 4 toward the rear and upwards, and takes a seat on the upper surface of the seat plate 1 in the upright state shown in FIGS. 1 and 3.

When the hand is released from the back plate 4, the back plate 4 comes into contact with the user's back and is prevented from rotating forward, but at this time, the center of gravity 0 of the back plate 4 Because it is located slightly forward from directly above, it does not put too much pressure on the user's back, and can be used like a regular chaise lounge with armrests.

Next, when the user leaves the chair, the center of gravity O of the back plate 4 is in front of the pivot shaft 7, so the back plate 4 automatically rotates forward about the pivot shaft 7, as shown in FIG. The back plate 4 and the seating surfaces of the seat plate 1 are in a state of being perfectly overlapped with the upper surface of the seat plate 1 as shown in the figure, and the seating surfaces of the back plate 4 and the seat plate 1 are kept clean without getting wet with rain or getting dirty with dust, so that your clothes will not get dirty next time. do not have.

In this way, the chair of the present invention has armrests with a center of gravity at the tips on both sides of the back plate which is pivotally connected to the seat plate, and is configured so that the center of gravity of the back plate is located forward of the lower pivot point. Although the configuration is extremely simple, the top surface of the seat plate can be covered by the back plate when not in use, and the inner surfaces of the back plate and seat plate are kept clean at all times without getting wet with rain or getting dusty, and can be used outdoors. Even if it is installed, it will not stain clothes when used.

[Brief explanation of the drawing]

FIG. 1 is a perspective view with the back plate erected, FIG. 2 is a perspective view with the back plate folded down, and FIG. 3 is a side view. 1... Seat board, 4... Back board, 12...
... Armrest, 0 ... Center of gravity device.

Claims (1)

[Scope of utility model registration request] A back plate of approximately the same size as the seat plate is pivotally attached to one side edge of the seat plate so that the back plate can be rotated in the front and rear direction. A chair with armrests and configured so that the center of gravity of the backboard is located forward of the lower pivot point.
