Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a movable partition wall which is suitably used as a low partition in an office or the like.

[Prior Art] Conventionally, as a movable partition wall of this type, there is one in which a plurality of panels are sequentially connected. However, in such a thing, not only are adjacent panels connected to each other by using engaging claws, but also strip-shaped connecting metal fittings are bridged between the upper frame members of those panels, and the connecting metal fittings are bolted. By fastening to the corresponding upper frame material, the connection strength between the panels is increased.

[Problems to be Solved by the Invention] However, in the case of only this, there is a problem in that the movable partition as a whole easily bends in the thickness direction due to loosening at the connecting portion by the connecting fitting. That is, since the mass-produced bolts that are generally used are formed by rolling, the outer diameter of the head knuckle is smaller than the outer diameter of the threaded portion. Therefore, such a bolt only has a function of fixing the connecting fitting to the upper frame member by surface friction, and cannot serve as a positioning pin. Therefore, when a large load is applied, a surface slip between the connecting metal fitting and the upper frame member is caused, and the panels other than the panel whose tilting is prohibited by the orthogonal panel or the like are tilted so that the upper edge side of the movable partition wall is curved. It may be transformed into. Recently, this type of movable partition wall is often supported by a cantilever such as a shelf or a desk top, and moreover, a weight comparison is made on the desk top such as a computer or a word processor. Since it is not uncommon to place and use relatively large equipment, a problem that the panels are loosely connected and the panels tend to tilt toward the load side is taken up as a major problem.

In addition, since the conventional connecting fitting has no function of drawing the panels together, a gap is likely to occur between the end faces of the connected panels. Therefore, there is a problem that the degree of freedom of operation of the panel is increased, the above-described surface slip is likely to occur even when a relatively small load is applied, and light leakage occurs at the joint portion.

The present invention aims to eliminate all such inconveniences.

[Means for Solving the Problems] The present invention takes the following means in order to achieve the above object.

That is, the movable partition wall according to the present invention comprises a plurality of panels, a horizontal pin, a connector, and a fastener, and the panel has grooves with tapered side surfaces. The horizontal pins are provided on the upper frame member, and the horizontal pins are fixed to each panel so as to be orthogonal to the groove, and the connector is a bridge between at least two panels. It is equipped with a taper part that can be adhered to both sides of the groove with taper, and a cutout part into which the horizontal pin of each panel is inserted.The fastener is designed to press the taper part of the connector into the groove of both panels. It is configured so that this connecting tool can be tightened in the direction in which it is made, and when the tapered portion of the connecting tool is pushed into the groove, a cam surface for urging the horizontal pins of both panels in the direction toward each other is formed. It is characterized in that it is provided in the cutout portion of the connector.

As a specific embodiment, the upper frame member is provided with a bottom wall having a groove with a taper and standing walls standing on both side edges of the bottom wall, and the horizontal frame is provided between the standing walls. It can be mentioned that a pin is installed.

If you want to facilitate the panel assembly work, temporarily set the temporary holding pins on the upper frame material of each panel and loosely fit these temporary holding pins to the connecting tool bridged between the panels. It is good to be able to do it.

In order to more surely prevent light leakage at the joint portion of the panels, it is preferable to provide concave and convex engaging portions on the end faces of the panels to be brought into contact with each other.

[Operation] With such a configuration, since the tapered portion of the connector is engaged with both tapered side surfaces of the groove provided in the upper frame member of the panel, the tapered portion and the groove Even if there is some variation in processing on both sides, by firmly tightening this connecting tool to the upper frame material with a fastener,
The taper portion and both side surfaces with the taper are surely brought into close contact with each other. As a result, the adjacent panels can be strongly connected in a state where they are accurately positioned, and the loosening hardly occurs. Therefore, the panel at the end portion where the tilting is prohibited by the sleeve panel or the like is accurately fitted with the other intermediate panel, and it is possible to prevent the problem that the entire movable partition wall bends toward the load side. In particular, this is the process of pushing the tapered part of the connector into the groove,
The guide function of the cam surface urges the horizontal pins fixed to each panel toward each other, so that by tightening the connecting tool to the upper frame member, it is possible to strongly press the end faces of the panels together. Become. As a result, the panels connected to each other lose their freedom of movement due to the pressure contact of the end faces, and a more reliable and strongly connected state can be obtained. Moreover, if the end faces are pressed against each other in this manner, light leakage can be prevented and the value as furniture can be improved.

In addition, the connection on the lower end side of the panel, such as using the engagement claw,
It may be performed by an appropriate means.

With such a structure, the taper portion of the connector 2
Since the 24 is engaged with the tapered both side surfaces 35a of the groove 35 provided in the upper frame member 31 of the panel 1, there is some processing variation between the tapered portion 24 and the both side surfaces 35a of the groove 35. Even if there is, by strongly tightening the connecting tool 2 to the upper frame member 31 with the bolt 5, the tapered portion 24 and the tapered both side surfaces 35a are surely brought into close contact with each other.
As a result, the adjacent panels 1 can be strongly connected to each other while being accurately positioned, and the loosening is unlikely to occur. Therefore, the panel 1 at the end portion where the tilting is prohibited by the sleeve panel or the like is accurately aligned with the other intermediate panel 1, and it is possible to prevent the problem that the entire movable partition wall bends toward the load side. . In particular, this is a cam surface in the process of pushing the taper part 24 of the coupling tool 2 into the groove 35.
The horizontal pin 36 fixed to each panel 1 is urged in the direction toward each other by the guiding action of 25a.
It is also possible to strongly press the end faces 1a of the panel 1 into close contact with each other by tightening them to 31. As a result, the connected panels 1 are deprived of the freedom of movement due to the pressure contact of the end faces 1a, and a more reliable and strongly connected state can be obtained. Moreover, if the end faces 1a are brought into pressure contact with each other in this manner, light leakage can be prevented and the value as furniture can be improved.

Note that the present invention includes a panel that does not have a concave-convex engaging portion on the end surface, but by providing the concave-convex engaging portion, it is possible to more reliably prevent light from leaking through the gap and becoming unsightly. can do.

Further, the present invention also includes a case in which the temporary holding pins are not provided, but if the temporary holding pins are provided on the upper frame material of each panel in a protruding manner, the adjacent panels can be connected to each other to some extent only by placing the connecting tool. It can be loosely connected in the positioned state. Therefore, it becomes possible to temporarily connect the required number of bolts and to fix the bolts continuously at one time, and the assembly work can be efficiently performed.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, it is possible to strongly connect adjacent panels with each other in a precisely positioned state without causing a problem such as a gap between the end faces. It is possible to provide a movable partition wall that can maintain the strongly connected state for a long period of time.
