Description

[Detailed description of the invention] This invention relates to a tool for rubbing the palm of the hand. There are no special tools for rubbing the palms of the hands; there are towels, brushes, etc., but even if you rub them with these tools, you don't get a particularly good feeling, and rubbing the palms itself does not attract much attention.

B. Structure of the idea This idea was created based on the fact that balsa wood gives a very good feel and what kind of posture makes it easy to rub the palm of the hand. To explain, a backing plate 2, which is also elongated and made of a strong material, is attached to the bottom of the rubbing plate 1, which is elongated and made of balsa wood. In the tool, two or three or more basic horizontal bars 3 having a thickness of It has a structure in which the side edge 4 of the plate 1 is formed into a smooth arc shape.

(b) How to use There are various methods, but the appropriate method is to sit straight or cross-legged, place the palm rubbing tool on the floor next to or in front of your body, place your palm on the surface of the rubbing board 1, and then apply your body weight. This is a method of rubbing while applying pressure. As you move the position away from your body, you have to stretch your hips,
It can also be used as a waist stretching exercise.

The next suitable method is to attach the basic horizontal bar 3 to an attachment tool and use this tool in a fixed manner. Adhesion tools include a bottom plate, a fixing stand, a bed, etc. When attached to a bed, the foundation horizontal bar 3 may be fixedly attached to the rear wall, side wall, handrail, or lower frame of the bed depending on the structure of the bed.

C. Effect of the invention The first effect of this invention is the effect of using balsa wood for the rubbing board 1. One of them is that balsa wood has no corners on the surface and if it is smooth, it feels good to the touch. So, if you rub it, make sure it feels good and doesn't hurt.
Generating heat in a shorter time than other materials, part 3
The first is that the equipment can be made lighter, and the fourth is that even in winter,
It should not make you feel stuffy.

The second effect is due to the fact that the backing plate 2 is attached below the rubbing plate 1. Balsa wood has low strength, so if you use balsa wood for the entire tool, you would have to make it into a member with a large cross section, but if you use balsa wood only on the surface that touches the palm of your hand, the strength will be
If you use the strong backing plate 2, the entire tool will be
You can make it smaller or you can make it longer.

The third effect is the effect of the foundation horizontal bar 3, one of which is to create a space of 1.5 cm or more between the floor and the backing plate 2. Because of this space, when the palm of the hand is heated on the surface of the rubbing plate 1, it is possible to place the fingers under the backing plate 2 and rub smoothly. 1.5cm
is the size of a child's thumb. The two of them do not have the basic horizontal bar 3, and are unstable with just the elongated backing plate 2, but if two or three or more basic horizontal bars 3 are attached, the tool will become stable when placed on the floor. It has the effect of The above effects are combined and you can rub it comfortably.

D. Shape and Others The width of the rubbing plate 1 may be the same as that of the backing plate 2 over its entire length, but it is better to make it wider.
The reason is that it is easy to make a recessed portion at the boundary between the rubbing plate 1 and the backing plate 2, and it is easier to rub when the thumb is placed on the recessed portion.

Also, when rubbing with one hand, a width of about 2 cm can be used, but a width of about 4 cm to 8 cm is appropriate. If you are rubbing both hands at the same time, it is better to make it wider.

The length of the rubbing plate 1 may be the same as that of the backing plate 2, or may be different.

The surface of the rubbing plate 1 may or may not have gentle unevenness vertically or horizontally as long as it is a smooth surface. in particular,
Both ends may be low and the middle may be high (Figure 5).

The longer the basic horizontal bar 3 is than the width of the scraping plate 1, the more stable this tool will be.
Around 20cm is appropriate. The shape may be curved in the vertical or horizontal direction, but a straight shape may be used (FIGS. 2 and 3).

Since the foundation horizontal bar 3 may come into contact with the floor, it may be better to apply anti-slip treatment.
In this method, a rubber with frictional resistance such as silicone rubber, plastic, fiber, etc. may be used on the surface, or a thread-like material may be wrapped around the surface.
The surface may be roughened. The number of rubbing plates 1 may be one or two.

The backing plate 2 may be made of wood, plastic, metal, or any other material. When the width of the rubbing plate 1 is narrow, one piece is sufficient, but when it is wide, two pieces may be used (Fig. 7).

The foundation horizontal bar 3 may be attached directly to the backing plate 2 (Fig. 1), but there are cases where it is better to raise the position of the rubbing plate 1. In that case, the backing plate 2 should have a high height. It is preferable to attach an adjustment piece 5 for adjustment, and attach the foundation horizontal bar 3 to this adjustment piece 5. At this time, it is preferable to form the inner side of the attachment portion of the adjustment piece 5 and the backing plate 2 into an arcuate concave surface 6, since this will disperse stress, reduce the cross section of the member, and make it easier to grip.

There are no restrictions on the shape or number of adjustment pieces 5.
When the width of the scraping board 1 is wide, adjustment pieces for the horizontal dimension are also required, and the number is as follows for each 31 horizontal horizontal bars of the foundation.
In some cases, two longitudinal adjustment pieces 5 and one horizontal adjustment piece 5 are required (FIG. 7).

Next, in the case of 12 rubbing plates, the rubbing plates of the same size and shape (Figs. 8 and 11) may be arranged in parallel (Fig. 9) or in a V-shape. (Figure 10). Items with different dimensions and shapes (first
2) may be arranged in parallel or in a V-shape.

If you want to concentrate stress on a local part of the palm,
The width of the rubbing plate 1 may be around 1 cm, but in that case, the width of the rubbing plate 1 may be narrower than the backing plate 2 (FIGS. 8 and 9).

As for the manufacturing method, the backing plate 2, the basic horizontal bar 3, the adjusting piece 5, etc. may be manufactured separately and then glued together, but if they are made of plastic or cast metal, they may be manufactured as one unit (Figure 13). . In those cases, the basic horizontal bar 3
A thickness of 1.5 cm or more is not necessary over the entire length.
It's fine if it's only partially. In the case of integrally molded products, the boundaries between each member are not clear, so the adjustment piece 5 and backing plate 2
In some cases, a part of the base horizontal bar 3 may also constitute a part of the foundation horizontal bar 3 (FIG. 13).

Furthermore, depending on how you use this tool, you can also rub the soles of your feet and thighs.
