JPS5810089B2 - Connecting desk with chair for lecture room - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting part with a chair used in a lecture room such as a school classroom or an auditorium. The desks are connected to each other by connecting the backs of the seat frames of the chairs of the front desks to the supports of the desks arranged in front of each other, thereby holding the seat frames of the chairs horizontally, while releasing the connection. This allows the chairs to tilt forward to reduce the overall front-to-back width, and by shifting the front and rear desks horizontally in a staggered manner, the front-to-back widths are brought closer together for lecture room use. An object of the present invention is to provide a connecting section with a chair.

Examples illustrating the present invention will be described below: 1.
Reference numeral 1 denotes left and right pillars that support the top plate 2, and 3°3 represents a grounding frame extending at right angles to the rear from the lower end of the pillars.

The pillars 1, 1 are provided with support arms 4, 4 which project horizontally toward the rear at their upper ends, and the top plate 2 is placed on top of the support arms 4, 4.

The top plate 2 in this embodiment has mounting brackets 5, 5 attached to the lower surface along the left and right side edges, and shafts 6, 6 protruding from the inner surfaces of the upper ends of the columns 1, 1 are attached to the pivot points of the mounting brackets. 7, 7, and is mounted so that it can be flipped forward about this shaft as a fulcrum, and is always supported horizontally by abutting the lower surface on the support arms 4, 4. be.

A shelf frame 8 having an angular cross-section is provided on the lower surface of the top plate 2, so that school supplies and the like can be stored.

As mentioned above, the left and right columns, on which the top plate 2 is flipped up and freely attached via the shafts 6, 6, are raised in parallel by the horizontal frame 9 that is passed halfway up the height, and the left and right columns extended from their respective lower ends are The grounding frames 3, 3 are arranged parallel to each other facing rearward.

This grounding frame is formed to be longer than the front and back width of the top plate 2, and the left and right legs 10, 10 of the chair are pivotably attached to each rear end thereof.

The legs 10.10 are each integrally formed with seat frames 11, 11 protruding rearward at right angles at their upper ends, and are formed in an inverted shape.The seat plate 12 is passed between the two seat frames. Keep the legs parallel to each other, and keep the legs 10 degrees parallel to each other.

These left and right legs 10.10 are pivotally attached to the grounding frame as described above, and in this embodiment, a bearing part 13.13 is provided on one surface of the rear end of both the grounding frames, and the bearing part 13.13 is provided inside the grounding frame from this bearing part. A support shaft 14.14 protruding toward the direction is rotatably pivoted to the leg ends of the left and right legs 10, 10, and the legs are attached so as to swing back and forth about the support shaft as a fulcrum. When it is folded down, it fits under the top plate along with the seat frame, and the legs fit between the left and right supports.

On the other hand, at the rear end portions of the parallel seat frames 11, 11, there is provided a concave connecting portion 16.16 that opens toward the rear of a reservoir that connects to a connecting portion 15.15 provided on the support column, which will be described later.

The connecting portions 15.15 provided on the above-mentioned support columns are provided in the horizontal frame 9 passing between both support columns, and are provided so as to correspond to each rear end of the seat frame, and the concave connecting portions 16 provided on the seat frame. .16
It is formed in a convex shape so that it fits in.

Both connecting portions 15 and 16 are provided with through holes 17 and 18 that vertically pass through them, and by passing a connecting pin 19 through these through holes, the two connecting portions can be integrally connected. .

In the figure, 20 is a backrest plate extending between the upper end front surfaces of the columns 1, 1, and 21 is a stopper protruding from the inner surface of the columns.

The connecting part with a chair of the present invention is constructed as described above, and in use, the connecting part 16 provided at the rear end of the seat frame 11° 11 is connected to the connecting part 15 of the support column through the connecting pin 19, The rear part of the seat frame is supported and the seat plate 12 is supported horizontally, and at the same time, the front and rear desks are connected in the front and back direction by this connection, and a plurality of desks are used by arranging them in a row as shown in Figures 2 and 3. I will do it.

Similarly, at the rear end of the row, two columns 30.3 corresponding to the columns 1, 1 are provided to horizontally support the seat frames 11, 11.
0, a grounding frame 31, 31 extending perpendicularly to the lower end of the support column in order to vertically support it, a horizontal rod 32 that extends halfway up the height of the support column, and a backrest plate that extends between the front surface of the upper end of the support column. 33, and a desk without a backrest plate 20 is connected to the desk connected to the front end of the row.

When each part connected in the above rows is stored, the connecting parts 15 and 16 are uncoupled by removing the connecting pin, and the chairs in each desk are connected to the pivot supports at the leg ends. The seat frame 11 and the seat plate 12 that are tilted forward using the shaft 14°14 as a fulcrum are folded under the top plate 2 and protrudes rearward, and the front and rear widths are reduced, and each part is organized in rows in this state. Bring them together.

In this case, the grounding frames 3, 3 protrude rearward from the lower end of the support from each part, but since the left and right grounding frames are parallel, it is necessary to shift the front and rear desks to the left and right by the width of the grounding frames. , it is possible to place the desks close to each other with their grounding frames next to each other, and as shown in Figure 5, it is possible to store a large number of desks together in a narrow space by stacking them together like weights. can.

In this case, if the top plate 2 is raised freely using the shafts 6, 6 as fulcrums as in the above-mentioned embodiment, it becomes possible to bring the top plate closer by the protruding width of the top plate, and it can be stored in a narrower space. Become.

As described above, the present invention enables the desks to be arranged in the front-rear direction by removably connecting the rear part of the seat frame and the support of the desk, and also supports the seat plate of each desk horizontally. On the other hand, by releasing the above-mentioned connection, the chair part that protrudes rearward can be folded under the top plate to reduce the front and back width, and by shifting the grounding frames of each part laterally, they can be brought closer to each other. Since they can be collected, they are convenient in lecture halls and the like because they can be collected in the corner of the room when not in use.

In addition, it is more effective if the top plate and the shelf frame can also be flipped up as described above at the time of this storage.

Incidentally, in the above embodiment, the seat frame 11 and the support column 1 are connected by the convex connecting part 15 and the concave connecting part 16, but it goes without saying that the relationship between the concave and convex portions may be reversed. However, it is not limited to this shape.

In short, the connecting means here may be any means that has a structure that allows them to be removably connected to each other and to horizontally support a seat that swings back and forth using a support shaft as a fulcrum, thereby supporting a seated person.

Additionally, it would be convenient if the connection could be attached and detached without using any tools.
