Description

[Detailed Description of the Invention] The present invention relates to a rubber band holder that holds rubber bands and makes it possible to reliably take out one rubber band at a time.

Generally, when taking out rubber bands stored in a case, not only do the rubber bands get entangled with each other and more rubber bands than necessary are taken out of the case, but the extra rubber bands that are taken out may fall and scatter on the way. However, it was extremely difficult to take out the rubber bands one by one with a single touch.

In view of the above points, the present invention provides a rubber band holder that has a simple structure, can be produced at low cost, and can reliably take out rubber bands one by one with a single touch.The structure is as follows. be.

The present invention comprises a pair of curved pieces made of an elastic material such as a synthetic resin in the shape of a band plate, curved in the thickness direction, and tapered in width at the tip.
This rubber band holder is characterized in that the inner circumferential surfaces of the side curved pieces are arranged to face each other, and the tips of the side curved pieces are biased so as to be brought into contact with each other with a slight vertical offset. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 show a first embodiment, where 1 is a first curved piece, 2 is a second curved piece, 3 is a shaft, and 4 is a case.

The side curved pieces 1 and 2 are formed into a band shape from an elastic material such as a synthetic resin, and are curved in the thickness direction, and the width dimension of the tip part is tapered.

Further, this tip may be formed into a radius. Side curved pieces 1, 2
A hinge portion 11.21 is provided at the base end of the hinge portion 1.
By fitting the shaft 3 into 1.21, the side curved pieces 1, 2
The inner circumferential surfaces of the two are opposed to each other, and they are continuous with each other at their base ends.

These side curved pieces 1 and 2 are slidably engaged with the shaft 3,
It is attached to a rectangular box-shaped case 4.

The case 4 has a rubber band storage section 41, with engagement holes 42, 42 for the shaft 3 provided on both sides thereof, and a horizontal surface 43.42 for supporting the side curved pieces 1, 2 at the upper front surface of the case 4. 43
and rising surfaces 44, 44 are provided, and a notch 45 is formed in the center thereof.

The shaft 3 is engaged with the engagement hole 42, 42 of the case 4, and the side curved pieces 1 and 2 are attached to the case 4.

In this case, the bottom surface 12 of the first curved piece 1 is brought into contact with the horizontal surface 43 of the case 4, and the lower back surface 22 of the second curved piece 2 is brought into contact with the rising surface 44 of the case 4, respectively.

By doing this, the side curved pieces 1 and 2 are urged inward,
These tips 13.23 are elastically brought into contact with each other.

The leading edge portions 13.23 of the image are slightly offset vertically, that is, in this embodiment, the leading edge of the second curved piece 2 is slightly lower than the leading edge of the first curved piece 1.

The means for this is to make the curvature of the side curved pieces 1 and 2 the same and have different lengths, or to make both the side curved pieces 1.2 the same length and have different curvature rates, so that the first curved piece 1 The height may be made higher than the height of the second curved piece 2.

In order to hold this curved piece with a rubber band, as shown in FIG. 5 through the first curved piece 1 or the second curved piece 2.

Alternatively, slide the side curved pieces 1 and 2 in the axis 3 direction,
After moving the second curved piece 2 to the notch 45 at the center of the front surface of the case 4, the second curved piece 2 is laid down inside the rubber band storage part 41.

By doing this, the contact points of the tips 13.23 of the side curved pieces 1, 2 are opened, so that the rubber band 5...
You can easily pass through...

Thereafter, the second curved piece 2 is raised, and the side curved piece 1.degree. 2 is slid in the direction of the axis 3 and set to the position shown in FIG. 1 or the opposite position.

The former method of forcibly opening allows the rubber band to be loaded quickly, while the latter sliding method is preferable in terms of fatigue strength because no load is applied to the curved piece.

Further, when this holder is not used, the side curved piece 1.2 can be moved to the central notch 45 and stored in the rubber band storage part 41 by lying it down.

Furthermore, a large amount of spare rubber bands can be stored in the rubber band storage section 41.

When removing the rubber band 5 attached to the holder, remove any rubber band 5 as shown in FIGS. 3 and 4.
Pinch one and pull it upward to open the contact point between the tips 13 and 23 of both curved pieces, and then pull out the rubber band 51.

In this case, it would be ideal to take out the top rubber band, but it may be difficult to pick the top rubber band when you cannot take your eyes off it during other tasks or when the rubber bands are intertwined. be.

With this holder, in such a case, the rubber bands can be reliably removed one by one.

That is, when taking out the rubber band held by the first curved piece 1, the rubber band 5 is pinched as shown in FIGS. 3 and 4.
The rubber band 52 located above the first curved piece 1 is lifted together and when it reaches the contact point, it passes over the tip 13 of the first curved piece 1, and the second curved piece 2
move to the side.

Also, the rubber band 53 that is below the picked rubber band 51 and is tangled and lifted together reaches the contact point, and the rubber band 51
When it is removed, it falls back to its original position.

When removing the rubber band 51, since the tips 13 and 23 of both curved pieces are in elastic contact with each other in a vertically different state,
The contact point opens while the second curved piece 2 shifts upward, and the contact point closes at the same time as the rubber band 51 is pulled out.

Since the structure is such that the contacts do not open more than necessary, it is possible to prevent excess rubber bands from being pulled out.

In addition, since the width of the tips of the side curved pieces 1 and 2 is tapered, the rubber band 52 located above the rubber band 51
smoothly moves to the second curved piece 2 side without getting caught on the corner.

Furthermore, if the width of the second curved piece 2 is made wider than the width of the first curved piece 1, the rubber band 52 will come into contact with the Kona part 20.20 at the tip and will be reversed using this as a fulcrum, so that the second curved piece will be smoothly curved. Move to the second side.

In this way, with this holder, the rubber bands can be reliably pulled out one by one, but of course several rubber bands can also be pulled out at the same time.

In this case, since the rubber bands 5 are coaxially held by the first curved piece, there is no risk of the rubber bands becoming entangled with each other as would be the case if they were simply stored in a box. They are naturally kept in alignment.

Therefore, even when multiple rubber bands are taken out at the same time, it is possible to take them out smoothly.

Moreover, the rubber band held on the second curved piece 2 can also be taken out basically in the same way as in the case of the first curved piece 1 described above.

However, in this case, there is a possibility that the rubber band 52 located above the picked rubber band 51 is blocked by the first curved piece tip 13 and is pinched by the contact point without moving to the first curved piece 1 side.

In this respect, as described above, it is desirable to take out the rubber band on the first curved piece 1 side, and it is desirable to return the rubber band that has moved to the second curved piece 2 side to the first curved piece 1 side.

A second embodiment of the present invention is shown in FIGS. 5 and 6, and a third embodiment of the present invention is shown in FIGS.
An example is shown in FIG.

Note that in the second and third embodiments, the same reference numerals are used for the same parts as in the first embodiment.

In the second embodiment, an L-shaped protrusion 14.24 is provided below the hinge portion 11.21 of the side curved pieces 1, 2 connected by the shaft 31.

Reference numeral 6 denotes a fixing base, which has a dovetail-shaped engagement part 61 on its upper surface, and the L-shaped protruding pieces 14 of the side curved pieces 1 and 2 are attached to this engagement part 61.
24 are slidably engaged.

At this time, by bringing the protruding piece 14.24 into contact with the inner surface 62° 62 of the engaging portion 61, the side curved pieces 1, 2 are urged inward, and the tips 13.23 of these are elastically pressed. They are in contact with each other.

The fixed base 6 serves as a weight, but a suction cup, a magnet, or the like may be provided on the bottom surface of the fixed base 6.

The retaining parts 61 of the fixed base 6 are provided on the left and right sides as shown in the figure.
Two sets of curved pieces can be attached to one fixed base.

In order to hold the rubber band on this curved piece, as described above, the side curved pieces 1 and 2 may be forcibly opened and the rubber band passed through, or the side curved pieces 1 and 2 may be removed from the fixed base and the rubber band passed through. .

On the other hand, in the third embodiment, the proximal hinge portion 1 of the first curved piece 1
1 and a proximal hinge portion 21.
The clip 7 is formed by a gripping piece 71 having a shape.

The upper protruding piece 72 of this gripping piece 71 is fitted into the engagement groove 25 which is provided at the lower end of the second curved piece 2 and has a U-shaped cross section.

The clip 7 described above may have a structure provided with a spring (not shown), but the elasticity of the side curved pieces 1 and 2 may also be used as spring force.

Moreover, in order to hold a rubber band on this holder, it is sufficient to pass the rubber band through the first curved piece 1 while the second curved piece 2 is removed from the grip piece 26.

As mentioned above, various structures of the proximal end fixing parts of the side curved pieces 1 and 2 can be considered, and modifications other than those described above may also be made.

However, in the present invention, such a fixing part is not necessarily necessary, and this fixing part may be omitted and the side curved piece 1.2 may be integrally continuous at the base end, or the base end may be attached to the fixing base. It can also be used as a directly attached structure.

As explained above, according to the rubber band holder of the present invention,
To easily hold rubber bands without complicated entanglement, to take out the rubber bands one by one with one touch, and to make the rubber band an excellent holding tool.
