Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member connecting device preferably used when connecting two members.

[0002]

2. Description of the Related Art For example, as one type of movable partition wall constructed by connecting a plurality of panels, vertical frame members constituting a structural frame of each panel are directly connected by bolts. There is something I did.

In such a type, for example, a nut element is provided on a vertical frame member of one panel,
The vertical frame members are coupled to each other by fastening a bolt inserted from the vertical frame member side of the other panel so as to be orthogonal to the joint surface to the nut element.

[0004]

However, when the bolts are fastened in the direction orthogonal to the joint surface as described above, for example, when the vertical frame members of panels with different heights are joined to each other, the horizontal If there is a member that prevents the bolt from being inserted in a direction orthogonal to the joint surface, such as a frame member, the bolt must be inserted while avoiding that position, and the connecting position is limited. I will end up.

Therefore, it is conceivable that the vertical frame members are connected to each other by using an inclined bolt arranged in a direction inclined with respect to the joint surface. There is a possibility of shifting in the vertical direction.

As a remedy for solving such a problem, for example, a positioning protrusion or a claw portion is provided on the joint surface of one vertical frame member, and the protrusion or the claw portion is formed on the joint surface of the other vertical frame member. A positioning hole is provided in which the claw part fits,
It may be possible to prevent the vertical frame members from being displaced along the joint surface even if the bolts are diagonally fastened.

However, if such projections and claws are provided on the vertical frame member, there arises a problem that the projections and claws become an obstacle when not used. For example, there is a desire to remove or replace only the middle panel without disassembling the whole, in order to change the form of the movable partition wall constructed. However, if such projections or claws are fixedly present, there is a problem that even if the bolts are removed, the projections or claws interfere with the removal of only the intermediate panel.

[0008] Such a problem can occur not only in the vertical frame material of the panel but also in the connection of various members.

[0009]

That is, the present invention has been made to solve the above-mentioned problems, and uses an inclined bolt in which two members are arranged in a direction inclined with respect to their joint surfaces. And a nut element that engages with an inclined bolt that is provided in the backing member and that is inserted from the other member side. , A shift preventing element which is provided on the backing member and can be retracted to a position where it does not obstruct when unnecessary, and a shift preventing element which projects from the backing member after insertion to position the other member and prevents the shift A preventive means is provided. The tilt bolt is
It includes one that is inserted obliquely from above and one that is inserted obliquely from below.

With such a structure, it becomes possible to prevent the vertical displacement caused by the connection by the tilted bolts by the displacement preventing element protruding only when necessary. Further, by retracting the shift prevention element, the insertion operation of the backing member can be smoothly performed.

Further, in order to simplify the structure without providing another mechanism for projecting the shift-preventing element, the shift-preventing means is made to project the shift-preventing element by utilizing the tightening force of the tilt bolt. It is desirable to configure

[0012] As a specific embodiment of such a shift preventing means, the shift preventing means is provided with a slider provided with a nut element and an element for guiding the slider so as to be capable of advancing and retracting within a required range. It can be mentioned that the shift preventing element is configured to project based on the movement of the slider by tightening the bolt.

Further, in order to reduce the number of parts and simplify the construction, a claw portion having a contact surface for positioning is integrally provided on the slider as a shift preventing element, and a positioning portion is provided on the other member. It is preferable that the claw portion is projected with the movement of the slider, and the contact surface of the claw portion is brought into contact with the positioning portion to position the other member.

In order to make the positioning by the claws more accurate, the contact surfaces of the claws are configured so that they can simultaneously contact the positioning parts of both members, and the two members to be joined together are joined together. It is desirable to perform the positioning directly via the claw portion.

Further, the backing member is provided with a movement inhibiting step portion for inhibiting the movement of the backing member at the use position, and the movement inhibiting step portion is adapted to be brought into contact with the positioning portion. In this case, in order to prevent a strong force from being applied from the member to the backing member at the contact surface of the movement-prohibiting step portion and the positioning portion when the members are joined together, the contact surface of the claw portion Is preferably positioned such that when the claw portion is most protruded, it can be applied to the positioning portion in preference to the movement prohibiting step portion. With such a structure, the casing of the backing member may be formed of a material such as synthetic resin having low rigidity, which increases the degree of freedom in selecting the material of the casing and enables cost reduction. .

Further, when the force of the member is applied to the claw portion, it is desirable that the claw portion is formed of a metal having rigidity such as iron. With such a structure, the claw portion can be repeatedly used.

In order to make the parts common and improve the manufacturing convenience, a seat receiving element for receiving the head portion of the inclined bolt for inserting into the other member of the backing member is provided. Is desirable. That is, by inserting the same backing member into each member, the members can be joined together.

As another aspect of the present invention, a backing member inserted into one member, a seat receiving element provided on the backing member for receiving the head of the inclined bolt, and the other member side. A nut element that engages with the tilted bolt, a shift-prevention element that is provided on the backing member and can be retracted to a position where it does not interfere when unnecessary, and this shift-preventing element is projected from the backing member after insertion. And the other member is positioned to provide a deviation preventing means for preventing the deviation. Note that, in such an aspect, the deviation prevention means may be, for example, one that causes the claw portion to project based on the pressing force applied to the seat receiving element of the bolt.

Further, in order to utilize the member coupling device of the present invention more effectively, it is desirable that the backing member be detachable so that it can be replaced at various places.

Further, as a target member for effectively exerting the effect of the member coupling device of the present invention, a vertical frame member which constitutes a structural member of a panel on which the panel element is mounted is desirable.

Further, if it is applied to the case where vertical frame members having different heights are joined together, the effect is more effectively exhibited.
