Description

DETAILED DESCRIPTION OF THE INVENTION The present application relates to a seat device that is temporarily installed on a floor surface, and includes a plurality of seat bodies each having a leg body having a pair of left and right legs extending in the front and back direction, and having a seat part that can be raised and lowered. and a treadle located at the front of the lower part of the seat body, the front cowl part and the rear part of which are folded into two in a mountain fold shape. The seat plate 1j is extendable and retractable to form a forest, and when not in use, the seat plate is folded in two into a mountain fold shape and erected between the seat bodies, so that the seat plate can be contracted in the front-rear direction.

Generally, when seats are temporarily placed on the floor, eζ is
It is necessary to arrange the folding chairs individually or to arrange several chairs connected together, but it requires a lot of effort to arrange the chairs and to store them when not in use. This has the disadvantage that the chairs cannot be arranged in an orderly manner, and since the chairs are arranged directly on the floor, a person sitting on the floor may walk directly on the floor, which may stain the floor. If the floor surface is damaged, it may be difficult to use it for other purposes, such as an athletic field.

Therefore, the present invention provides a seating device that is easy to arrange and store, and that prevents the umbrella from getting dirty or damaged.

An embodiment of the present application will be described below with reference to the drawings.

In the figure (11C (111, (lb), (1 stone...
] indicates the seat rate alone, and each seat unit is a leg (2)
, a plurality of seat bodies (3), and an m-plate (4). The leg body (2) consists of a pair of horizontal leg parts t21a and f2To on the left and right sides of the fall, and the base part (2) c is fixed to the horizontal frame on the rear side between the horizontal legs t21a and f2To. is the pillar (2

There are multiple ground rollers (5) facing S in the lower border. Each seat body (3) has a seat (3 backrests + 311)
It consists of the armrest (3)C and the seat part (3- is the leg fI@
It is pivotally connected to the support frame part (2) of the part so that it can be raised and lowered, and this pivot part has a built-in spring member so that the seat part (3-) stands diagonally upward when the seat is not seated. +31c is
The support frame part (21eK) is erected and pivotally connected to the upper end of the support frame (3) 6 so as to be able to rise and fall, and is kept in an upright state when not in use. a and the second half (4
) b, and these are connected by a hinge (6) so that they can be folded into a mountain fold, and this tread (4) is attached to the upper surface side between the horizontal legs (21a, +2To) of the leg body (2). It is suspended horizontally so that it can be placed, and the rear edge is attached to both horizontal legs (2Jb) from hinges (7) K so that it can be raised and lowered.

Both horizontal legs i1s (21a, (2T
There is an actuator between o and the treadle (4)! (8) is provided. In other words, this operating mechanism (8) has one horizontal leg (

91 and the rear half (4)b of the treadle (4) in the vertical direction
Ql, Ql protruding support arm piece αB,
One end of the aυ is pivotally connected to the bracket Gi, (11), and the other end is movably engaged with the guide slot (91, (91) through a sliding pin a, ab K.

Each seat unit configured as described above (11[(1)a
.

The leg (2) of (ib, tllc -...') has one horizontal leg (21 m).

12T) is configured so that the horizontal legs of the front row legs can be inserted into the horizontal leg holes of the rear legs 1j in a nest-like manner by changing the intervals of the front row legs 1j.

The horizontal leg portions 121a, f2To of the front row leg (21), which are inserted in a nested manner in this way, and the horizontal leg portions (21m, +2b of the rear row leg body 21) are interconnected.

That is, the horizontal leg portion 1215t located in the front row, the rear end Kpij' of f2To, and the sliding pin 03. When Q3 is fixed and the front leg (2) moves forward, the sliding pin 0. a4 is also a guide slot (91, (slides forward along 93, rear part of the rear step board (4) +4) b is a support arm piece Q

) When the front row legs (2) move backwards with respect to b stands up via the support arm piece (111, an t-), and the footboard (4
The first half (4)a of ) is also folded into a mountain fold shape and stands up.

Therefore, the seat unit (o ((ha, (1 skin (lla・

When the legs (2) of the front row (k) are pulled out forward, the subsequent legs (2) are also pulled out one after another and arranged at the required intervals, and in this state, each tread (4) is also automatically pulled out. It is laid down and placed on the horizontal legs (21a, (2)b) of each leg body (2), respectively, and is configured as shown in the second row.In this state, the seat part of the seat body (3) f3) a) Lay down against the meeting spring member, and fold down the armrest (31c t-horizontally)
This allows the user to sit more easily, and the user must walk on the footboard (4) when changing the seating position.

In addition, when not in use, the legs (2) of the outermost seat unit (lla) are pulled rearward (by which the legs of the subsequent seat units (21411) are moved rearward, and the seat units located in the front row are (Horizontal leg part 121m of leg body (2) of lla, (2
To is inserted between the horizontal leg parts 121m and 12Jb of the seat unit body (1 stone leg body (2)) located in the back row. During this insertion movement, the supporting arm piece Qll.

an is the rear half of the treadle (4) (bt bracket) 11
1. Press Ql' and push up, and the tread (4) is erected and rotated as a fulcrum by the horizontal leg of the leg (7), and the horizontal leg of the 6118 leg When the footboard (4) is fully inserted into the horizontal leg of the rear leg up to a predetermined position fi1, the footboard (4) is folded into a mountain fold as shown in FIG.

Meanwhile, supporting arm piece Q11. (It stands up almost vertically with the lυ interposed between the seat bodies (3) of the front and rear rows.

In addition, since the seat bodies (3) are close to each other, the longitudinal dimension of the entire device is reduced by the width K11l, for example, 41l in the room.
It can be pushed to one side and contracted.

It should be noted that the operation of raising and lowering the tread of the seat unit in the front seat unit and the operation of moving the entire device back and forth can also be performed manually, but for example, the leg of the seat unit (L-
Of course, this may be done by moving the left and right sliding bins a'a, a'at-t-motorized in the front and rear directions using a known power mechanism such as an electric ridge or a fluid creation mechanism. .

As described above, the seat am according to the present invention has a pair of left and right horizontal 11 parts flJIKi [S parts that can rise and fall freely against sag].
A plurality of seat units each including a seat body having Yt and a treadle that can be folded into a mountain fold shape and that rises and falls with the rear edge as a fulcrum are arranged so that the horizontal leg portions of each leg body are nested into each other in the front and rear direction. Since it is configured to be arranged continuously in a shape, when in use, each seat unit can be moved forward and arranged in a simple and orderly manner with the required distance from each other in the front and back direction.
The tread is laid down horizontally across both horizontal legs of the leg, allowing the seated person to walk freely on the tread without fear of contaminating the entire floor surface or causing damage. When not in use, the treadle folds into a mountain fold and stands up.

Since this is located between the seat bodies of each seat unit, and the seat bodies are also close to each other, the space in the longitudinal direction of the entire device can be significantly reduced, and the device can be stored in a contracted state on a wall side, etc. It has the advantage that the floor surface can be widely used for other purposes when not in use.
