Description

[Detailed Description of the Invention] / [Field of Industrial Application] The present invention relates to a movable partition wall that is suitably used as a low partition in offices and other places.

[Prior Art] Conventionally, as this type of movable partition wall, there is one in which a plurality of panels are successively connected. However, in such devices, not only do adjacent panels be connected using engaging claws, etc., but also strip-shaped connecting metal fittings are bridged between the upper frame members of the panels, and the connecting metal fittings are connected with bolts. By fixing them to the corresponding upper frame material, the connection strength between the panels is increased.

[Problems to be Solved by the Invention] However, with just this, there is a problem in that the connecting parts by the connecting fittings become loose and the entire movable partition tends to bend in the thickness direction. That is, generally used mass-produced bolts are manufactured by rolling, so the outer diameter of the head bolt is smaller than the outer diameter of the threaded portion. Therefore, such a bolt only has the function of fixing the connecting fitting to the upper frame member by surface friction, and cannot play a role like a positioning pin. Therefore, when a large load is applied, plane slipping occurs between the connecting fittings and the upper frame material, and the panels other than those whose tilting is prohibited due to orthogonal panels, etc., tilt, causing the upper edge of the movable partition wall to curve. It may transform into. These days, movable partition walls of this type often support shelf boards, desk tops, etc. in a cantilevered manner, and what's more, there are computers, word processors, etc. on top of the desk tops that are relatively heavy in weight. As large equipment is often used, the connections between the panels become loose and the panels tend to tilt toward the load side, which has become a major problem.

Further, since the conventional connecting fittings have no function of drawing the panels together, gaps are likely to occur between the end faces of the connected panels. Therefore, the degree of freedom of movement of the panel is increased, and even when a relatively small load is applied, it is easy to cause the above-mentioned surface slip, and there is a problem that light leakage occurs at the joint portion.

The present invention aims to eliminate all such problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention takes the following measures.

That is, the movable partition wall according to the present invention includes a plurality of panels, horizontal pins, connectors, and fasteners, and the panels have tapered grooves on both sides. The horizontal pin is fixed to each panel perpendicular to the groove, and the connector is a bridge between at least two panels, and the horizontal pin is fixed to each panel at right angles to the groove. The fastening device includes a tapered portion that can be tightly attached to both tapered sides of the groove, and a notch portion into which a horizontal pin of each panel is inserted, and the fastening device pushes the tapered portion of the connecting device into the groove of both panels. When the tapered part of the connector is pushed into the groove, the cam surface for biasing the horizontal pins of both panels in the direction of It is characterized by being provided in the notch of the connector.

In a specific embodiment, the upper frame material is provided with a bottom wall having a tapered groove, and upright walls provided on both sides of the bottom wall, and a horizontal wall is provided between the upright walls. One example is installing pins.

If you want to smoothly assemble the panels, set temporary holding pins upright on the upper frame material of each panel, and loosely fit these temporary holding pins into the connector bridged between the panels. It is best to have it ready for use.

In order to more reliably prevent light leakage at the joining portions of the panels, it is preferable to provide uneven engagement portions on the end surfaces of the panels that are to be brought into contact with each other.

[Function] With this configuration, the tapered part of the connector is engaged with both tapered sides of the groove provided in the upper frame material of the panel, so the taper part and the groove are Even if there are slight variations in processing on both sides, by strongly tightening this connecting tool to the upper frame material with the fastening tool, the tapered part and both tapered sides will be tightly crimped securely. . As a result, adjacent panels can be strongly connected to each other while being accurately positioned, and loosening is less likely to occur. Therefore, the other intermediate panels accurately follow the end panels whose tilting is prohibited by the sleeve panels, etc., and it is possible to prevent the problem that the entire movable partition wall bends toward the load side. In particular, in the process of pushing the tapered part of the connector into the groove, the horizontal pins fixed to each panel are urged toward each other by the guiding action of the cam surface. By tightening the material, it is also possible to strongly press the end surfaces of the panels together. As a result, the degree of freedom of movement of the connected panels is taken away due to the pressure contact of the end faces, and a more reliable and strong connection state can be obtained. Furthermore, by pressing the end faces together in this manner, it is possible to prevent light leakage and improve the value of the furniture as a piece of furniture.

Please note that the lower end of the panel can be connected using an engaging claw, etc.
This may be done by any appropriate means.
