Description

[Detailed Description of the Invention] The present invention relates to a connecting device that makes it possible to connect several pipes in any direction to a pipe in which a large number of holes are arranged in order on one side to form a shelf support, etc. More specifically, the box has both sides and a bottom protruding rearward, a vertical slit in the center of the front, and an open top, which can be inserted into a hole in a pipe attached to the front and hung, and a base that can be hung. a first connector having an insertable T-shaped hook at its tip and capable of fitting and fixing into a joint pipe; a protruding piece protruding from the rear side of the picture body; and a bottom plate protruding from the rear of the bottom part. and a second connector having a hook shaped like a cross section at its tip, which can be inserted into the space formed by the back surface of the box and the side surface of the back plate of the base, and which can be fitted and fixed to the joint pipe. This invention relates to a coupling device.

Conventionally, when constructing a structure such as a shelf support at a predetermined position of an upright pipe column, a large number of insertion holes are drilled on each of the three sides of the pipe column, and hooks are inserted into the insertion holes and fixed. The structure was designed to have pipes extending in one direction or two directions, but drilling a large number of insertion holes of this kind on three sides of a pipe column is a difficult task, resulting in extremely high costs and the pipe length. This had the disadvantage of significantly weakening the strength of the pillars.

The device according to the present invention is a completely new technology developed in view of the drawbacks of the conventional technology.

To explain the connecting device according to the present invention with reference to figures, in Figs. It is a hanging base with a plug-in piece 4 that can be stopped protruding from a central back plate 5, and on the front of the central back plate 5 there is a box 7 with an open top and a vertical slit 6 in the center of the front surface. This box 7 is attached
Both side surfaces and the bottom surface protrude from the back surface of the box 7 to form a protruding piece 8 and a bottom plate 15, and a space is formed between the protruding piece 8, the bottom plate 15, the back surface of the box 7, and the back plate 5. ing.

Reference numeral 9 denotes a first connector, which has an external shape that allows it to be inserted and fixed into the pipe 10, and has a top end that is connected to the picture body 7 of the suspension base 3.
A horizontal section T-shaped hook 11 that can be inserted into is protruded.

Reference numeral 12 denotes a second connector, which has an external shape that allows it to be inserted and fixed into the pipe 10, and whose tip is connected by the back plate 5 of the base 3, the bottom plate 15, the protruding piece 8, and the back surface of the box 7. A hook 13 in the shape of a horizontal cross section is protruded and can be inserted into the empty space formed.

In the above embodiment, the hooks 11 and 13 are connected to the connectors 9 and 1, respectively.
The hook 11 protrudes vertically from 2 by the thickness of the pipe 10, and when the pipe 10 is attached to the connectors 9 and 12, the hook 11
, 13 and the outer circumferential surfaces of the pipe 10 are flush with each other.

When assembling the device according to the present invention, as shown in FIGS. 2 and 3, the suspension base 3 is inserted and locked into the insertion hole 2 of the pipe column 1, and the connectors 9 and 12 are connected to the pipe. 10 and fit it, and then connect the T-shaped hook 11 of the connector 9 to the image body 7 of the base 3.
Insert it from above and fix it, then move to connector 1
The key-shaped hook 13 of 2 is inserted into the space formed by the pipe column 1, the protruding piece 8, the back of the picture body 7, the back plate 5, and the bottom plate 15, and is fixed. It is possible to construct a structure such as a shelf support from which the pipe 10 is projected.

In the above embodiment, the case where two insertion pieces 4 were provided on the base 3 was explained, but the suspension of the base 3 and the connecting tool 9
, 12, as shown in FIGS. 4 and 5, the base 3 is extended vertically and three insertion pieces 4 are provided protruding from it, and the base Hook 1 attached to 3
1.13 can also be configured to be longer.

Also, as shown in FIGS. 4 and 6, instead of the pipe 10, a T
It is also possible to prepare a shelf support plate 14 having a letter-shaped hook 11 and attach it to the base 3.

Furthermore, it is not necessarily necessary to provide a bottom plate at the bottom of the base 3 as described above, and as shown in FIG. , hook 1
By attaching a predetermined taper or reverse taper to the side surfaces of the hooks 1 and 13, it is also possible to lock the hooks 11 and 13 inserted into the base 3 by this taper.

As described above, the device according to the present invention is a hanging device that is constructed by installing an insertion piece on the back side of the picture body with a vertical slit in the center of the front face, an open top part, and the side and bottom parts protruding backwards through a back plate. The lower base and the picture body and two types of connectors with hooks that can be inserted and fixed to the sides of the picture body, or shelf plates with hooks, are combined with each other. After fitting the connector to the pipe and suspending and fixing the base to the pipe column, by inserting and fixing the hook into the base, a number of holes can be inserted in any direction of the pipe column that has an insertion hole on only one side. It is possible to easily attach individual pipes or shelf supports, and therefore there is no need to drill insertion holes on three sides of the pipe column as in the past, making it extremely inexpensive to manufacture and durable. The connecting device is characterized by good workability because the entire connecting device can be attached and detached very easily.
