Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a leg member for a table, a counter, a platform on which a top plate can be folded.

[Conventional technology]

Most of the leg members in conventional folding tables and the like are assembled from pipes and the like in a substantially ⊥ shape, a substantially shape, and a substantially □ shape when viewed from the side.

Since the leg members are attached to the left and right sides in the length direction of the rectangular top plate, the folding of the top plate is performed with respect to the left and right leg members. It is a model that folds upright.

[Problems to be solved by the device]

Since the folding of the top plate only raises the top plate toward the front side or the rear side of the left and right leg members, the left and right widths of the top plate are the same as in use. It cannot be folded smaller than the width.

There is also a type in which the top plate is erected in the left and right directions, but this type has a structure in which the top plate itself is folded into a wing shape or an inverted wing shape through a hinge member in the middle. Since it is a type in which the leg members that can be folded are attached to these left and right top plate members as well as forming, there is the problem that the structure becomes complicated and the number of parts increases, as well as folding and extending operations. It is complicated and there is a non-negligible problem that there is a high risk of so-called finger stuffing when the top plate itself is folded.

In view of the problems of the conventional folding table as described above, the present invention stands the top plate on the right or left side of the left and right leg members without folding the top plate itself. The problem was to develop a leg member that can be folded.

[Means for Solving the Problems]

The structure of the present invention made for the purpose of solving the above-mentioned problems is one base member formed to have a substantially boomerang shape with an included angle of about 90 degrees to 45 degrees, preferably about 60 degrees when viewed from the plane. , Left of the base member,
Two columnar members that are respectively provided upright on the upper surface side of the intermediate portion of the right member, and provided with a top plate receiving portion that is attached to the bottom surface of the top plate such as a table and performs a hinge operation at the upper end of each of the two columnar members.
It is characterized by comprising a columnar member of a book.

[Action]

A boomerang-shaped base member having an included angle of about 90 to 45 degrees, preferably about 60 degrees, receives the load of the top plate through the column member standing upright in the middle portion of the left and right members thereof, so that the base member It becomes possible to support the vertical load by the top plate erected on the right side or the left side near the center of gravity or the center with good balance, and in this state, the standing posture of the top plate can be stably maintained.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 is a front view of an example of a folding table provided with an example of a leg member of the present invention, FIG. 2 is a right side view of the table of FIG. 1,
3 is a bottom view of the same, FIG. 4 is a left side view of the same in a folded state, FIG. 5 is a front view of another example of a folding table provided with an example of the leg member of the present invention, and FIG. FIG. 5 is a right side view of the table of FIG. 5, FIG. 7 is a bottom view of the table, and FIG. 8 is a left side view of the same in a folded state.

In FIG. 1 to FIG. 4, 1 is a plane substantially circular shape, but a part of the outer circumference is a substantially circular arc shape having a small curvature (large radius) from the viewpoint of design or practical use. 1a is a formed top plate. Of course, the planar shape of the top plate 1 is not limited to that shown in the drawings.

Reference numeral 2 is a base member formed by casting, die casting, injection molding or the like so as to have a substantially boomerang shape when viewed from a plane. The left and right members 2l and 2r are slightly curved thin triangles.
Is formed to have a substantially ∧ shape when viewed from the bottom surface with an included angle (or crossing angle) of about 60 degrees.

The base member 2 may be formed of a pipe material, a mold material, or the like by welding, screwing, or the like so that the material has the outer shape of the illustrated example.

Designated by 3l and 3r are rollers attached to the ends of the left and right members of the base member 2. In the present invention, the wheels 3l and 3r may not be provided.

4l and 4r are two left and right columnar members which are erected on the upper surface side of the base member 2 near substantially the center of the left and right members 2l and 2r, and their upper ends are on the back surface of the top plate 1. Left and right hinge cover members 5l and 5r that are fixedly attached and these cover members 5
Inside the l, 5r, one of the hinges is one of the pillar members 4l, 4r.
Left and right hinge members (not shown) attached to the upper edge of the
And are installed. The other of the hinges is attached to the back surface of the top plate or the cover side.

Thus, the cover members 5l, 5r and the hinge members arranged at the upper ends of the columnar members 4l, 4r are attached to the back surface of the top plate 1, so that the top plate 1 is attached to the base member 2. The table shown in FIG. 1 is formed into the posture of the table in use.

In FIGS. 1 to 4, reference numeral 6 denotes a lock release lever of the hinge member, which prevents the top plate 1 from arbitrarily operating against the columnar members 4l and 4r which are legs in the state shown in FIGS. This is for unlocking the locked hinge member. 6l is a connecting rod for the left and right levers 6.

When the table in the posture of the above-described description and the use state shown in FIGS. 1 to 4 is pushed (or pulled) with the lock release lever 6 facing upward, the lock by the hinge member (not shown) is released, and the hinge is released. Top plate 1 integrated with cover members 5l and 5r
Is placed on the columnar members 4l, 4r in a state in which it can stand up about a hinge shaft (not shown in the drawing) of the hinge member (the top plate 1 is rotatable clockwise in FIG. 1).

Therefore, when the top plate 1 is rotated in the clockwise direction in FIG. 1 by about 90 degrees in this state, the hinge member is locked again at the completion of the rotation of 90 degrees and the top plate 1 shown in FIGS. Hold it upright.

Here, the standing and folded top plate 1 is upright in a direction parallel to the axes of the wheels 3l and 3r of the base member 2,
In addition, the base member 2 having a plane boomerang shape has a relationship in which the convex side 2a of one base member 2 is substantially fitted into the concave side 2b of the other base member 2 (shown by a chain line in FIG. 3). Thus, a plurality of tables in which the top plate 1 is folded can be arranged in close proximity to each other in a substantially serial state.

By the way, in a conventional folding table having left and right leg members having a side ⊥ shape, etc., even if the top plate is erected forward or backward with respect to the leg members and folded up, a plurality of tables can be placed in this state. When arranging before and after, since the leg members interfere with each other next to each other, the leg members are laterally displaced so as to be adjacent to each other.
In other words, the folded top plates can be arranged only so as to be shifted leftward or rightward.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 to 8, the same symbols as in FIG. 1 indicate the same members or the same parts.

The top plate 11 of this embodiment is a long top plate having a substantially rectangular shape (the top plate shown in the drawings is slightly curved from the viewpoint of practical use and design), so that the leg members are left and right of the top plate. However, only one of the leg members L ₁ is formed by the leg member of the present invention.

And Thus, the other leg member L ₂ are compared with one leg member L _1, it is different from the configuration and the leg member L ₁ in that it does not include a base member 2 forming a flat boomerang shape. Also, the lock release of the hinge member of the leg member L ₁ is performed by the lock release lever 61 disposed on the leg member L ₂ side via the connecting rod 7, which is also different from the previous embodiment. Lock release lever 61
Why provided on the side of the leg member L _2, upon standing folding of the top plate 11, the columnar member 4l in the leg member L _2, 4r also folded so as to be parallel orientation relative to the lower surface of the top plate 11 This is because

Thus, in the folding of the top plate 11, in the use state shown in FIGS. 5 to 7, the lock release lever 61 is operated to unlock the hinge member, and the left side of the top plate 11 shown in FIG. While manually lifting the column in the clockwise direction of FIG. 5, fold the columnar members 4l, 4r of the leg member L ₂ in the counterclockwise direction, that is, on the back side of the top plate 11, and vertically stand the top plate 11 (the leg member L It is folded in the state shown in FIG. 8 by rotating it upright with respect to ₁ ).

[Effects of the Invention] The present invention is as described above, and even if the top plate is a long object, it can be folded in a standing posture in its length direction and held in that posture, so that it can be occupied in a folded state. The area (planar projected area) can be reduced.

Also, due to the rolling wheels provided only at the end of the base member, it is impossible to move in the static state (when in use), but it can be moved easily by slightly floating the other side of the top plate (leg side without rolling wheels). It is possible to

Further, the upright folded top plate stands upright in a direction parallel to the axis of the wheel on the base member, and the base member having a plane boomerang shape is such that the convex side of one base member 2 is the other base. By substantially fitting the concave side of the member, the folding table of the top plate has a unique effect that many of them can be arranged in close proximity to each other in a substantially serial state.
