Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in pipe joints, devices for joining multiple pipes. The pipe joint of the present invention is particularly useful in the interior and display fields.

BACKGROUND ART A combination of pipes and joints that connect them is often used as a method of constructing sectional furniture or so-called unit shelves. Conventionally, this type of pipe joint was
If you want to connect two pipes in parallel, for example, you can make square-shaped metal fittings by pressing sheet metal, place them facing each other and fix the center part with a screw-nut, or if you want to connect them crosswise, you can use a so-called method. If you use a cheese-shaped connector, you can join the pipes together in a beautiful and stylish manner.
Moreover, no convenient means of joining could be found to attach shelves or cupboards to the frame constructed from pipes.

The present invention improves these points and provides a pipe joint suitable for interior and display applications.

The first pipe joint, which is an example of the present invention, connects two pipes in a T-shape in the same plane.
Explaining with reference to FIG. 2 and FIG.
Blocks 2 and 3 having 7, 28 and 37, 38 face each other and sandwich the pipe to form a rectangular parallelepiped, and when tightening the screw to grasp the pipe, the male screw 4 is connected to a countersunk head screw. By cutting a female thread in block 2 that engages with the male screw, and providing a notch 35 in block 3 into which the countersunk head fits, the male screw 4 is completely buried in blocks 2 and 3 when tightened. That's true. As a result, when the pipes are connected, the joint 1 has a rectangular parallelepiped appearance and no bolt heads or nuts protrude from the outside, so it is not only safe but also simple and beautiful. From this point of view, it is preferable that the female threaded hole 26 provided in the block 2 be a blind hole without being penetrated.

Another and more important point is 1.
The surface of at least one of the blocks in the set that is parallel to the axis of the pipe and the outer periphery of the pipe are at the same height. The structure is such that the pipe is in contact with the pipe. In the illustrated example, a pipe 10 and parallel surfaces 21 and 31 are shown.
as well as the pipe 11 and the plane 22 parallel to it.
and 32 pairs have the above relationship. The pattern is as shown in FIGS. 2A and 2B, and in detail in FIG. 2C.

Due to this configuration, the pipe joint of the present invention provides the advantage that it does not protrude beyond the diameter of the pipe in certain planes. Of course, the effect of this is that the joints are beautiful, but even more so, we should pay attention to the benefits in combination with other constituent elements. To explain an example in FIG. 3, when a shelf board 20 is placed on a vertical pipe 10 and a horizontal pipe 11 connected by a pipe joint 1, the upper surfaces 22 and 32 of the joint are Since it is in the same plane as pipe 11, there is no gap between shelf board 20 and pipe 11, and therefore, pipe 1
1 will be supported. Conventional pipe joints that do not take this kind of consideration have their upper surfaces above the pipe diameter, so the shelf board 20
is supported only in the vicinity of the vertical pipe 10, resulting in bending. This not only spoils the aesthetic appearance, but also raises concerns about strength in some cases.

The pipe joint of the present invention can have various embodiments. For example, in the example above,
If it is desired that the bottom surface of the block also coincide with the surface of the pipe, the shapes shown in FIGS. 4A, B and C may be adopted.

The embodiment shown in FIG. 5 is used for the joint that connects two pipes in parallel. The pattern of its use is as shown in FIG. That is, blocks 2A and 3A having recesses 27, 29 and 37, 39 corresponding to the outer diameters of pipes 10, 10, respectively, are also fastened with countersunk head screws 4. In this case, both end surfaces 21 parallel to the pipe
and 31, and each pair of 23 and 33 is connected to pipe 1.
This is a plane containing tangents to the outer circumferences of 0 and 10.

FIG. 6 shows a case in which cupboards 8, 8 are combined with the combined pipe framework in place of the shelf board 7 in FIG. 4. The pipe joint 1A mentioned above is
Two vertical pipes 10, 10 are connected in parallel,
Moreover, since the cupboards 8, 8 can be installed with the side walls in close contact with these pipes, it is preferable from the viewpoint of stability and aesthetics.

The pipe joint of the present invention can be made of any material such as metal or plastic.
In the case of metal, it may be carved from a block, but
Manufacturing methods such as die casting are suitable for mass production, and injection molding is also advantageous for plastic materials. The surface may be subjected to a desired surface treatment such as polishing, plating, electrolytic coloring, painting, etc. in accordance with the relationship with that of the pipe. It is also interesting to use transparent materials as long as they are strong enough.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) Two pipes can be created by sandwiching the pipe between two blocks 2 and 3, each having a recess that matches the outside diameter of the pipe, and tightening the pipe with a screw 4. In the pipe joint that connects the pipes, the two blocks 2 and 3 have an almost rectangular appearance when holding the pipe between them, and the screw 4
is a countersunk head screw, and is set so that it is buried in the blocks 2 and 3 when tightened, and at least one set of end faces 21 and 31 of both blocks 2 and 3 is set so that the pipe is in contact with the surface connecting them. Pipe joint 1 characterized by the following configuration. (2) A utility model registration request for a structure having a recess that connects two pipes in a parallel state, with both end surfaces 21, 31 and 22, 32 of both blocks 2 and 3 configured so that the pipes are in contact with the surfaces that connect them. Pipe joint 1 in the first term of the range. (3) It has a recess that connects two pipes in a T-shape, and connects one end surface 21, 31 and at least one of the upper surfaces 23, 33 or the lower surfaces 24, 34 of both blocks 2, 3 to the surface connecting them. Pipe joint 1 according to claim 1 of the utility model registration claim, which is configured so that the two are in contact with each other.
