Description

[Detailed description of the invention] [Industrial application field] This invention is attached and fixed to the wall of the kitchen, the side of a refrigerator, etc., so that wrap film or aluminum foil wrapped in a box for food can be easily taken out and retained in the box. , relates to a mounting structure for a pressing spring that presses the side surface of the box in a wrap film holder.

[Prior art and its problems] Conventionally, the attachment of the elastic spring in this type of wrap film holder has been carried out by fixing one end of the elastic spring to the back plate with screws, which is extremely difficult. It takes time and effort, and if the screws are not tightened too loosely, it will cause looseness, weakening the elastic force of the compression spring, and conversely, if the screws are too tightened, they will cause cracks in the compression spring, weakening the fixing force. Ta.

[Purpose of the invention] It is an object of the present invention to provide a mounting structure for a resilient spring that allows the resilient spring to be easily installed and fixed without using screws and without causing loosening.

[Structure of the invention] A concave surface of a required area is provided at one end of the back plate, and the vertical edge on one side of the concave surface and the back plate are connected by an inclined surface, and the back plate is made to face the front of the concave surface. A restraining piece is provided flush with the plate, and a mounting piece is provided extending from one end of the elastic spring through a bent part, and the front surface of the outside edge of the mounting piece is chamfered. The piece is inserted from the inclined surface between the recessed surface and the restraining piece to be fixed.

[Embodiment] In the figure, reference numeral 1 denotes a back plate formed on a vertical plane, and bottom plates 2, 2' are horizontally protruded from the front at a position intermediate to the lower end of the back plate. Front walls 3 and 3' are erected to form storage chambers A and B for boxed wrap films. Nail holes 4, 4 are provided in the left and right positions of the upper part of the back plate 1, and mounting shafts 6 for suction cups 5 are vertically provided at both left and right ends of the back surface.

7, 7' are the front walls 3,
It is an arc-shaped elastic spring whose one end is attached to the front right end of the back plate 1 so as to be opposite to the spring 3'.

Therefore, the present invention relates to the mounting structure of the elastic springs 7, 7' to the back plate 1, and includes rectangular recessed surfaces 8 provided near the right end of the back plate 1 in the storage chambers A and B, respectively.
The left end vertical edge of the recessed surface 8 and the back plate 1 are connected by an inclined surface 9, and a restraining piece 10 is provided flush with the back plate 1 at the lower right corner facing the front of the recessed surface 8. In the embodiment, an opening 11 is provided in the concave surface 8 at a corresponding position to the restraining piece 10.

On the other hand, a mounting piece 13 having an area corresponding to the recessed surface 8 is extended from the right end of the elastic springs 7, 7' through a bent portion 12 having a predetermined angle. A chamfer 14 is provided at the lower end and right end of the mounting piece portion 13, and further,
A cut groove 15 is provided in the upper half along the bent portion 12.

The elastic springs 7, 7' formed in this way are constructed by inserting the tip of the mounting piece 13 from the inclined surface 9 into the recessed surface 8, and with the back surface of the mounting piece 13 supported by the recessed surface 8, The lower end is supported by a restraining piece 10 and firmly fixed.

In addition, the rigidity of the elastic springs 7 and 7' is reduced by the cut grooves 15 provided in the bent portion 12, so that the elastic springs 7 and 7' can be used without pressing the wrap film box moderately and causing positional deviation, or without excessively pressing the wrap film box. , can be held securely, and furthermore, the mounting piece part 13
This makes it easier to operate when inserting into the recessed surface 8.

Other embodiments are shown from FIG. 6 onwards.
As shown in the figure, the upper and lower ends of the concave surface 8 and the back plate 1
A slit-like opening 16, 16 is provided between them. On the other hand, the width of the mounting piece 13 extending through the bending part 12 is set to the elastic spring 7, 7'.
An extension piece 17 with a width wider than 7' is provided, and a chamfer 1 is formed on the front surface of each edge of the mounting piece 13 and the extension piece 17.
4 is being carried out.

These elastic springs 7, 7' are formed by recessing the extension piece 17 at the upper end of the mounting piece 13 and forming a slit-shaped opening 16 at the upper end of the surface 8.
, and push up as it is to clear the lower end of the mounting piece 13 from the restraining piece 10 , then press down along the concave surface 8 and insert it into the opening 16 at the lower end, so that the bent part 13 connects the restraining piece 10 and the back plate 1 At the same time, the lower part of the mounting piece 13 is supported by the restraining piece 10, and the mounting piece 13
With the central part of the back surface supported by the concave surface 8, an extension piece 17 extending upwardly projects upward from the opening 16 and is supported and fixed to the back surface of the back plate 1.

[Effects of the invention] As described above, the mounting structure of the compression spring of the present invention is such that the mounting piece extending from one end of the compression spring is held in the gap between the recessed surface provided on the back plate and the restraining piece. Because it can be installed easily with one touch, it also takes time and effort to attach with conventional screws, and it eliminates the lack of elastic force of the compression spring that occurs due to over-tightening and under-tightening of screws. It is also possible to eliminate the problems caused by this, and to always exert a constant elastic force to reliably continue to support the boxed wrap film.
