Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a device for connecting walls such as partitions, wall panels, and fences with their end surfaces in contact with each other. be.

[Prior Art] The size of each wall in a partition or the like is standardized to a certain size, and several walls are connected or disassembled as necessary. When connecting such wall bodies, it is necessary that the connecting device is not exposed on the wall surface and can be firmly connected in order to prevent deterioration of the appearance due to its nature.

By the way, as a device similar to such a device for connecting walls, Japanese Utility Model Publication No. 12344/1973 discloses a device for connecting plate-like members of furniture with their side end surfaces in contact with the other member. A combination of a connecting rod and a substantially hollow disk-shaped rotating fastener is disclosed.

In other words, when connecting plate-like members with their side end surfaces in contact with a mating member, the base of a rod-shaped connecting rod having a large-diameter locking head at the tip is attached to a threaded cylindrical portion embedded in the mating member. While being screwed together, the plate-like member is provided with an insertion hole extending perpendicularly to the side end surface and a mounting hole communicating with the insertion hole and opening to the wide side of the member.

The connecting rod is inserted into the insertion hole so that its locking head faces the mounting hole, and a rotary fastener having a generally hollow disk shape and an eccentric inner circumferential surface in the shape of a cam is inserted into the mounting hole so that the inner circumferential surface engages with the locking head,
When the rotary fastener is rotated, tension acts on the connecting rod, pulling the two members together and connecting them to each other.

With this configuration, members can be easily assembled by rotating the rotary fastener, and since both the connecting rod and the rotary fastener are hidden within the thickness of the member, the appearance may not be deteriorated. do not have.

[Problem that the invention attempts to solve]

However, in this prior art, it is necessary to form a pair of connecting parts in which one member has a mounting hole into which the rotary fastener fits, and the other member has a threaded tube. If one of the plurality of walls provided near the left and right ends of the connecting part is rotated and arranged, the threaded cylinder parts and the mounting holes will face each other, and the connection in this state will not be possible. becomes impossible.

In addition, since the connecting rod is simply screwed into the threaded tube portion of the mating member, the connecting rod is likely to come off when tightened, and since the members must be aligned while fastening, positioning is difficult. It was a hassle.

Although the connecting device of the present invention utilizes the connecting rod and rotating fastening body as in the prior art, it has been improved to avoid the above-mentioned drawbacks, and allows walls to be easily connected to each other. The object of the present invention is to enable connection and disassembly, obtain a strong connected state, and ensure mutual positioning of wall bodies without requiring much effort.

[Means for solving problems]

In order to achieve this object, the present invention provides a connecting device for connecting the end surfaces of adjacent wall bodies by bringing them into contact with each other, and a concave groove into which a longitudinal edge member is fitted is provided in the middle part of the end surfaces of both wall bodies. and in both the walls, an insertion hole that penetrates the bottom of each of the grooves and extends parallel to the wide side of the wall, and an insertion hole that communicates with each of the insertion holes and opens on the wide side of the wall. A connecting rod with a locking head at both ends is inserted into both the insertion holes, and the rotating fastener fitted in each of the mounting holes is inserted into the locking head of the connecting rod. and an eccentric inner cam surface that communicates with the notch opening, and each of the locking heads is attached to each of the inner cam surfaces. The structure is configured such that tension in the axial direction is applied to the connecting rod by rotation of both rotating fasteners in a state in which the two rotating fasteners are engaged. It is characterized by forming a positioning protrusion that straddles and fits.

[Effect]

With this configuration, the connecting rod inserted into the insertion hole from the end face of the wall can be attached to and removed from both walls, and since both walls are provided with rotating fasteners, it can be said that the connecting rod can be inserted into the insertion hole from the end face of the wall. The structure is symmetrical, and the walls can be rearranged as desired, and the walls can be connected and disassembled extremely easily, and a strong connection can be maintained.

Since a positioning protrusion is formed in the middle of the connecting rod to fit across the grooves of both walls, when the connecting rod is passed between the two walls and fitted, the positioning protrusion is in contact with the grooves in the width direction (thickness direction of the wall) at the ends of both the left and right walls, and the positioning protrusions are used to position the grooves on both walls so that they do not shift from each other in the width direction. can do. As a result, the wide surfaces of both wall bodies are positioned so as to be aligned, and the wide surfaces can be connected to each other in a state in which they are continuous in substantially the same plane.

〔Example〕

Next, a description will be given of an embodiment in which the present invention is embodied as a connection device for partition panels.

In the figure, reference numerals 1 and 1' denote partition panels serving as walls that are connected in substantially the same plane by a connecting device to be described later, and both panels 1 and 1 covered with 12 cloth are supported at their lower ends by legs 2. At the same time, one side end surface of one panel 1 is connected to a support 3 so that the panel 1 can be erected.

Concave grooves 4, 4' of appropriate depth are formed along the longitudinal direction on each outer peripheral end surface of each panel 1, 1, and each concave groove on the mutually abutting end surfaces of both panels 1, 1' The grooves 4, 4' are configured to face each other, and a longitudinal edge member 5 made of synthetic resin having a substantially arcuate cross section is fitted into each of the grooves 4, 4'. Note that the grooved grooves 4, 4 are formed on the left and right end surfaces of the panels 1, 1',
In other words, they may be formed only on the surfaces that come into contact with each other.

Then, each of the groove grooves 4, 4' is provided at appropriate upper and lower portions of the left and right side edges of each panel 1, 1'.
An insertion hole 6 is drilled through the bottom surface and extends in a direction perpendicular to the side end surface of each panel 1, 1', and a mounting hole 7 that communicates with the insertion hole 6 and opens on one wide side of each panel. Set up Note that the edge member 5 is not stretched at this insertion hole 6 portion.

Reference numeral 8 denotes a rod-shaped connecting rod for connecting both panels 1, 1', and locking heads 8a, 8a connected to the small diameter shaft are formed at both ends of the connecting rod 8.
A positioning protrusion 8b having a substantially rectangular cross section and fitting across the opposed grooves 4 and 4' is formed in the center thereof in a symmetrical shape with respect to the axis. That is, the positioning protrusion 8b is a substantially rectangular strip having a width dimension that is substantially the same as the width dimension of the grooved groove strips 4, 4', and a vertical length longer than this width dimension.

Then, the connecting rod 8 is inserted into both the insertion holes 6, with the protrusion 8b fitted across both the grooves 4, 4'.
6, so that both locking heads 8a, 8a face the respective mounting holes 7, 7.

Reference numeral 10 designates a pivoting fastener for engaging each of the locking heads 8a and drawing the panels 1, 1' together. The rotary fastener 10 has a substantially hollow disk shape, and the locking head 8a of the connecting rod 8 is inserted into the rotary fastener 10 on one of the side plates 10a and 10b. A crescent-shaped notch opening 10c is formed in the other side plate 10, and a long slot 10d for inserting a tool such as a screwdriver is formed in the other side plate 10, while the outer peripheral surface of the rotary fastener 10 communicates with the notch opening 10c. A groove 10e is provided in the inner circumferential direction over an appropriate arc length, and the wall thickness t between the outer circumferential surface and the inner circumferential surface at the groove 10e is the thinnest at the notch opening 10c, and as it becomes farther away from the groove 10e. It is formed on an eccentric inner cam surface that gradually becomes thicker. By the rotation of the rotary fastening body 10, the lower neck portion of the head 8a of the connecting rod 8 inserted through the notch opening 10c fits into the groove 10e, and then is pulled toward the center of the fastening body 10 and fastened. Configure it so that you can. Reference numeral 11 is a cap made of soft synthetic resin or the like that closes the mounting hole 7.

In addition, when connecting one panel 1 to the support column 3, a conventional type of connection is used in which the locking head 8a is provided only at the tip of the shaft and the base end is screwed into the mating member. Rod 8' is used.

In order to connect both panels 1 and 1' in the above configuration, first, insert the connecting rod 8 across the insertion holes 6 and 6 located at the same height position in both panels 1 and 1', and
With the positioning protrusion 8b straddled and fitted to both the concave grooves 4, 4', their side end surfaces are brought into contact. Then, both the locking heads 8a, 8a of the connecting rod 8 protrude into the respective mounting holes 7, 7, so that the rotary fastener 10 is placed so that its notched opening hole 10c faces the locking head 8a. (i.e., the left and right sides are reversed from the state shown in Fig. 5), and then insert the slot into the long slot 19d.
All you have to do is insert a screwdriver into it and turn it. To disassemble it, just do the opposite. In this way, a large number of panels 1, 1', . . . can be connected or disassembled into a single plate.

In this connection work, when the positioning protrusion 8b of the connecting rod 8 is fitted across the double concave grooves 4, 4', the positioning protrusion 8b connects the double concave grooves 4, 4'.
4' in the width direction, and as a result, panel 1,
1' can be prevented from shifting in the thickness direction, and as a result, both panels 1, 1' are aligned with their wide surfaces aligned on the same plane.

If the panels 1, 1' are thicker than a certain level, two grooves 4, 4' are formed on each end surface, and the insertion holes 6 and mounting holes 7 are formed in the panels 1, 1'. Two holes may be formed on both the front and back sides, and the two connecting rods 8 may be used to connect the two connecting rods 8 at the same height. In this case, the rotating fastener 10 is the panel 1,
It will be inserted from both wide sides of 1'.

It goes without saying that the connecting device of the present invention can also be applied to vertically connecting walls.

[Effect of idea]

In this invention, a locking head is provided at both ends of the connecting rod, and the walls are connected by the locking head provided on both walls, so that the connection and disassembly of the walls is easy. This is extremely simple and can be done by only rotating the rotary fastening body, and since the rotary fastening bodies are locked at both ends of the connecting rod, the connection can be firmly made without coming off from the wall.

Further, in the connected state, the parts are not exposed to the outer surface of the wall, and the appearance will not be deteriorated.
In addition, since only the same-shaped insertion holes and mounting holes are drilled in the abutting surfaces of each wall, each wall can be formed in the same shape, improving productivity and improving productivity. Since they can be connected even if they are turned upside down (or upside down), there is no need to pay attention to the direction when connecting, which improves work efficiency.

In addition, opposing grooves are formed on the end faces of the wall, and a positioning protrusion is formed in the middle of the connecting rod to span over and fit over both of the grooves. Through this, deviation in the width direction of the facing double concave grooves in the adjacent wall bodies is regulated. As a result, simply by inserting the connecting rod between the two wall bodies, it is possible to completely prevent the occurrence of a step between the wide surfaces of the two wall bodies, and to connect them into a single plate. Furthermore, since the positioning protrusion of the connecting rod is fitted across both facing grooves of the adjacent wall, the connecting rod cannot be slid in its axial direction. Even if the fastening body and the other rotating fastening body are rotated separately, the two walls can be connected to each other.
