【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The furniture handle 5 of the embodiment is attached to the upper surface of the front plate 2 of the drawer 1 such as a desk as shown in FIGS.

The handle 5 has an arcuate surface at both ends in the longitudinal direction, and has an upper member 10 having a C-shaped cross section (which is a substantially inverted C-shape in the drawing) and divided in two in the lateral direction. , The lower member 20, and the lower member 20. The upper and lower members 10 and 20 are integrally molded by injection molding from a hard synthetic resin such as low-foaming polystyrene.

As shown in FIGS. 1 and 2, the upper member 10 includes an upper wall 11, a front hanging portion 12 extending downward from a front edge of the upper wall 11, and a rear wall 13 extending downward from a rear edge of the upper wall 11. And, it has.

The rear wall 13 has a lower end located above the lower end of the front hanging portion 12. Further, a recess 14 into which a welding projection 22 of a lower member 20 described later is fitted is formed on the lower surface of the back wall 13.

The lower member 20 includes a main body 21 whose upper surface is joined to the lower surface of the rear wall 13 of the upper member 10, and three cylindrical dowels 24 projecting downward from the lower surface of the main body 21. ing .

On the upper surface of the main body 21, a welding protrusion 22 that fits into the recess 14 of the rear wall 13 of the upper member 10 is formed. On the upper surface of the welding protrusion 22, a plurality of welding beads 23 are formed. Has been.

The manufacture of the handle 5 of the embodiment will be described. The upper and lower members 10 and 20 are formed by injection molding in advance. The molding dies used to form the upper and lower members 10 and 20 are each composed of two split molds having split surfaces at arbitrary positions on the horizontal line shown in FIG. The upper and lower members 10 and 20 can be molded without using a core.

Then, by fitting the welding projection 22 into the recess 14 and welding the back wall 13 and the main body 21 by ultrasonic welding, the upper member 10 and the lower member 20 can be joined. Then, the handle 5 can be manufactured.

After that, an adhesive is applied to the upper surface of the front plate 2, and the mounting holes 3 formed in the upper surface of the front plate 2 are fitted with the recesses 24 so that the lower surface of the main body 21 is attached to the upper surface of the front plate 2. If bonded, the handle 5 can be attached to the front plate 2 of the drawer 1.

If they are joined together, they can be manufactured easily and easily.

Since the direction in which the handle 5 is divided into the upper member 10 and the lower member 20 is divided in the lateral direction of the handle 5, an undercut portion is not generated in the upper member 10 and the lower member 20. In addition, the upper member 10 and the lower member 20 can be molded by injection molding, and the molding can be performed without using a slide core or the like for these molding dies, so that the die cost can be reduced.

Therefore, in the handle 5 of the embodiment, although the joining process is required, the operations such as cutting, chamfering, painting, and mounting of the dowel, which are required in the conventional manufacturing process, are unnecessary. Further, since it is possible to eliminate the need for a slide core or the like and suppress an increase in die cost of the upper and lower members 10 and 20, manufacturing man-hours and manufacturing costs can be reduced as compared with a conventional handle.

By the way, in the case of the conventional product, from the cutting to the mounting of the dowel, the production of 100 pieces per person per day was the limit, but in the case of the example, welding takes 3 seconds. Since the handle 5 of the embodiment can be manufactured, the number of manufacturing steps can be reduced to a position of several hundred minutes. Further, the manufacturing cost of the handle 5 of the embodiment can be reduced to about 1/3 that of the conventional product.
