Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention is based on the invention in which a plurality of plates of the same shape are joined together to form a 151
The present invention relates to an assembly board for making an assembly structure of T-pieces, and is particularly suitable for use in various types of assembly shelves, furniture, walls, etc. that require easy assembly and disassembly.

(Prior Art) An assembly plate in which a flat plate body NL having retaining portions M on the side surfaces is combined with each other to form a single plane or a box body is well known in the art. In addition to 1Mi standing shelves and assembling furniture, it is also widely used in construction materials and assembling toys in the form of building blocks.

(Problems to be Solved by the Invention) However, in the above-mentioned assembly plate, the structure of the engaging portion provided on the periphery is determined for forming a series of flat surfaces or for forming a refracting surface. 2fi! to assemble a general assembly structure with surfaces. A similar assembly plate is required, and the retaining part of each assembly plate is usually shaped simply by combining a concave part and a convex part, and many require some kind of fixing means after connection. From, assembly,
There is an inconvenience in that disassembly requires a lot of effort.

(Means for solving the problem) On the other hand, in this invention, although the plates have the same shape,
5KL allows for both planar and right angle connections.
Moreover, the combined plates and their own weight are used to fix each other to each other.

(Embodiment of the invention) An embodiment of the invention will be explained with reference to the drawings.
A) and (B) show a plan view and a front view of one of the plates according to the present invention. On one side of the two long sides thereof, locking protrusions 1, 1 protruding with a width equal to the thickness of the plate are formed, and on the other side, locking protrusions 1, 1 are provided. Matching engagement notches 2, 2 are respectively arranged at corresponding positions. In this case, the locking protrusions 1, 1 are connected to both end faces of a square rod 1a having a square cross section with a length equal to the thickness of the plate body, a square pyramid 1b whose bottom plate is a square end face, - The engaging notches 2, 2 are formed in an integrally connected shape, and the engaging notches 2, 2 have a contour that matches the projected contour of the locking protrusions 1, 10, that is, the square bar 1a.
, la and the square pyramids 1b and lbt' are each formed into a notch having a shape in which isosceles triangles are added to both ends of a rectangle that surrounds the outline of the plate when viewed from the front. In the embodiment shown in FIG. 1, these locking protrusions 1, 1 and engagement notches 2, 2 are provided only on one set of two parallel sides, but as shown in FIG. They may be provided in pairs, and the lengths of the top and bottom sides are the minus of both sides; in this case, they can be combined to form one wide plane, a right-angled surface, and a surface orthogonal to these surfaces. I can do it.

(Operations and Effects) With the above-described configuration, the present invention, for example, connects a large number of plates by engaging the locking protrusions 1 with the engagement notches 2 of the other plates, so that they can be combined into one plate as shown in FIG. They can be connected sequentially along a plane to form a single wide wall, or as shown in Figure 3, a large number of plates can be combined at right angles to each other, and some parts can be combined along a plane to create a display shelf. I can do it. in this case,
The conventional method in which an engagement protrusion having the same shape as the engagement notch is simply fitted into an engagement notch requires two tools, one for forming a flat surface and one for forming a right-angled surface.

If an external force is applied in the engagement direction, there is a disadvantage that each retaining member will immediately come off, but in this invention, both ends of the retaining protrusion 1 pass through the triangular vertices of the retaining notch 2. Because it is formed at the apex of a square pyramid that engages in orthogonal lines, the plate of the same shape can be used for both planar and orthogonal forms, and the plate can be held in a cantilevered state as shown in Figure 4. When the plate is supported, the outer corner 1c of the locking protrusion 1 and the apex 1d of the square pyramid 1b are brought into contact with the inner corner 2a of the engagement notch 2 due to the weight of the plate.

Since it acts as a wedge force held at each of the triangular corner portions 2b, the plate is prevented from escaping. This also applies to the case of engagement in the right angle direction.

As described above, this invention can be assembled by simply fitting the retaining parts together lightly, and there is no risk of them coming apart. It is suitable for use as a display shelf that utilizes the front and rear surfaces of FIG. 3, and is extremely efficient.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and FIGS. 1(A) and 3(B) are a plan view and a front view showing one of the plates, FIG. 2 is a front view showing the state assembled on a partition wall, and FIG. FIG. 4 is a perspective view showing a state assembled on a display shelf, FIG. 4 is an explanatory view of main parts showing an engaged state, and FIG. 5 is a front view showing another example of FIG. 1(B). In the figure, I indicates a locking protrusion, 2 indicates an engagement notch, 1a indicates a square bar, and 1b indicates a square pyramid.

Claims (1)

[Claims] A flat plate material of the required thickness is cut out to form a locking protrusion in the shape of a square bar with a square cross section on one side of two parallel sides, with square pyramids connected to both ends, and on the other side. For assembly, a plate is provided with an engagement notch having a contour matching the projected contour of the locking protrusion at a corresponding position, and a plurality of these plates are formed as a set.
