JP 2004-270330 A JP 2005-97955 A

In the partition wall 1, the connection between the support rail 4 and the accessory 5 is formed in a circular arc shape that is curved upward from the opening end in the depth direction (width direction of the support rail 4) as shown in FIG. 6. The engaging protrusion 51 of the accessory 5 formed in a curved cross-sectional shape corresponding to the concave groove 41 of the support rail 4 is inserted from the front of the wall panel 3 and engaged, and the rear end of the accessory 5 is inserted. When the portion 52 abuts against the wall panel 3, the engaging protrusion 51 is engaged and connected to the concave groove 41, and the accessory 5 is supported horizontally along the support rail 4. In this state, even if a book or the like is placed on the accessory 5 and a downward load is applied to the accessory 5, the rear end portion 52 of the accessory 5 is pressed against the surface of the wall panel 3 by the downward load. The engaging protrusion 51 does not come off from the concave groove 41.
However, when the front end 53 side of the accessory 5 is lifted upward and the rear end 52 is separated from the wall panel 3, the engagement protrusion 51 is easily detached from the concave groove 41. For example, when a person who has been bent and worked in front of the partition panel 1 stands up without noticing the accessory 5 and hits the body against the accessory 5, the tip 53 side of the accessory 5 is lifted upward in time. In some cases, the engaging protrusion 51 is detached from the concave groove 41 and dropped from the support rail 4, so that the accompanying articles 5 together with the books are dropped on the floor surface F.

  In view of the above-described problems of the prior art, the present invention reliably and stably fixes an accessory that is horizontally supported by a support rail to a support position, and prevents the accessory from dropping from the support rail. This is the issue.

  In order to solve the above problems, the present invention newly develops a fixture that fixes an accessory with the support rail supported by the accessory, and attaches the fixture to the accessory so that the accessory is detached from the support rail. Prevented.

More specifically, an accessory that is suspended on a support rail by engaging an engagement protrusion provided in a corresponding cross-sectional shape with a concave groove of a cross-sectional arc shape of a support rail installed on a wall panel such as a partition wall. The fixing tool is simultaneously brought into contact with the connecting portion with the accessory on one side and the lower edge of the opening end of the concave groove of the support rail on the other side, and the groove upper surface and the groove lower surface on the rear side of the opening end. Protrusions were provided.
The connecting portion is formed in a U-shaped frame shape that fits a rear end portion of the accessory, for example, when the accessory is a book shelf, and a protrusion that abuts the concave groove of the support rail at the upper end of the rear portion of the connecting portion. The part can be formed.

The fixture of the present invention is a state where the protrusion is inserted into the concave groove of the support rail while the incident protrusion of the accessory is engaged with the concave groove of the support rail and the accessory is supported by the support rail. Are attached to the accessory, and the fixture is fixed to the accessory integrally. The fixing tool is provided in a shape in which the protrusion is simultaneously in contact with the lower edge of the opening end of the recessed groove of the support rail and the groove upper surface and the groove lower surface at the back of the opening end. Therefore, in the state where the protrusion is inserted into the concave groove and brought into contact with the inner surface of the concave groove, the vertical displacement on the connecting portion side of the fixture is restricted, and thereby the accessory fixed to the connecting portion is vertically moved. The movement in the direction is restricted, and the accessory can be held horizontally without falling off the support rail.
The fixture of the present invention can be formed by an appropriate material and processing method such as aluminum mold processing or plastic injection molding. Further, the accessory that is fixed by the fixing tool can be applied to an appropriate usage such as placing or supporting an arbitrary article other than books in addition to those used as a bookshelf.

A preferred embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a fixture according to an embodiment of the present invention, FIG. 2 is a front view of the fixture, and FIG. 3 is a diagram showing a partition wall in which a fixture is attached to an accessory, with the main part broken. 4 is an enlarged cross-sectional view of a state in which the protrusion of the fixture is brought into contact with the concave groove of the support rail. In each figure, the same reference numerals are given to the same components as those of the conventional partition wall.

  The fixture 10 in the form shown in the figure is formed in the concave groove 41 of the support rail 4 formed in an arc shape in a cross section that is curved upward from the opening end in the depth direction, and has a corresponding curved cross-sectional shape. The accessory protrusion 5 of the attached accessory 5 is engaged to fix the accessory 5 supported by the support rail 4 and is formed by bending a plate material having an appropriate thickness and width into a substantially U-shape. It is.

  More specifically, as shown in FIG. 1 and FIG. 2, the fixture 10 has an upper surface portion 12 and a lower surface portion 13 projecting in parallel at the upper and lower end portions on one side of the beam portion 11, and From the upper end on the side, the protrusion 14 is formed so as to protrude from the upper surface portion 12. The beam portion 11, the upper surface portion 12, and the lower surface portion 13 constitute a connecting portion 15 that is connected to the shelf plate 54 of the accessory 5, and the end portion of the shelf plate 54 is fitted in a frame that is opened in a U-shape of each portion. Thus, the fixture 10 is provided so as to be integrally fixed to the rear end portion of the accessory 5. Further, the protrusion 14 has a thickness that can be inserted into the groove 41 of the support rail 4, and the protrusion 14 inserted into the groove 41 is formed at the opening end of the groove 41 as will be described later. It is provided in a shape that simultaneously contacts the groove upper surface and the groove lower surface on the back side of the lower edge and the opening end.

  As shown in FIG. 3, the fixture 10 formed in this way supports the accessory 5 on the support rail 4 by engaging the engaging protrusion 51 of the accessory 5 with the concave groove 41 of the support rail 4. In this state, the protrusion 14 of the fixture 10 is inserted into the concave groove 41 of the support rail 4 from the front of the wall panel 3 and is slid along the support rail 4 as it is, so that the connecting portion is formed from the side of the accessory 5. 14 is fitted to the end portion of the shelf plate 54 and the fixture 10 is fixed to the accessory 5 integrally.
