Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment capable of moving a moving object by attaching it to the bottom surface of a moving object such as a baggage such as a trunk case, a glass plate, a pottery, a metal plate, a stone material, and small household items. The present invention relates to a free moving aid.

[0002]

2. Description of the Related Art Conventionally, a moving object such as a trunk case with a caster could be rolled and carried.
Since the trunk case without casters was lifted by hand and carried, it was labor intensive. FIG. 8 shows a general structure of a caster of a moving object with casters. As shown in this figure, the caster 800 includes a pedestal 801 and wheels 803 attached to the pedestal 801 via a bearing mechanism 802 (details are omitted). On the other hand, as shown in FIG. 8, it was screwed and fixed by bolts 804.

[0003] In this caster, when a rotational force acts, the wheel can freely rotate 360 degrees by the bearing mechanism 802, so that the moving object moves not only in the front and rear limited directions but also in any direction desired by the user. Let me do. In addition, since the moving object is screwed and fixed to the moving object, even when the moving speed of the moving object or the weight of the moving object is relatively large,
It can withstand it.

[0004]

However, if the above-mentioned conventional caster 800 is used to carry a moving object which is not provided with casters in advance, it is generally necessary to screw and fix it. It is inevitable that the moving object will be damaged.
Since a screw tightening tool must be used, attachment and detachment cannot be performed easily. Therefore, the type of the movable body that can be attached is limited, and if the movable body is not allowed to be damaged, it cannot be attached.

In view of the foregoing, the present invention has been made in view of the above-mentioned problems, and has as its object to provide a moving assisting device capable of rolling and transporting a moving object without a caster, An object of the present invention is to provide a moving aid that can be easily performed without damaging it.

[0006]

In order to achieve the above object, the present invention comprises a pedestal and wheels, wherein the pedestal has a substantially flat mounting surface, and the mounting surface has an adhesive, A layer or a member to be attached to the bottom surface of the moving object by magnetic attraction, physical attraction or engagement is provided, and the wheel has a part thereof on the lower surface of the pedestal opposite to the attachment surface. It is characterized by being supported in an exposed state.

Here, it is also possible to use a single wheel and to be rotatably attached to a substantially central portion of the lower surface of the pedestal. In this case, it is also possible to adopt a configuration in which the wheel is a sphere and is wrapped and held on the lower surface of the pedestal so that it can roll in all directions. Specifically, the attachment surface may be provided with an adhesive tape, a magnetic sheet, a suction cup, a needle, or a magic tape.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a moving aid according to an embodiment of the present invention. * Configuration FIG. 1 is a perspective view of a movement aid 1 according to the present embodiment.

As shown in FIG.
Is composed of a pedestal 10 and wheels 20. FIG.
2A is a sectional view taken along line XX in FIG. 1, and FIG. 2B is a front view taken along arrow Y in FIG. 1. As can be seen from this figure, the pedestal 10 has a notch near the apex of the square pyramid, and has a recess 11 in the notch. The spherical bearing 12.
The spherical wheel 20 is rotatably fitted with a part thereof exposed to the lower side through the intermediary of. Specifically, after the wheel 20 is put in the recess 11, the wheel 20 is held in the recess 11 by attaching the frame 13 to the pedestal 10 from the opening 11 a side of the recess 11. Here, it should be noted that the dimensions of the concave portion 11 and the sphere are designed so that a part of the sphere serving as the wheel is exposed below.

Here, the center point O of the wheel 20 is designed to be exactly at the center of the pedestal (this will be described later). The upper surface 14 of the pedestal 10 is a flat surface having no convex portion. Here, an adhesive sheet 30 having the same area as the surface is taken with the adhesive surface facing upward (upward in the drawing). Is being worn.

The dimensions of the pedestal 10 and the wheels 20 are designed according to the size and weight of the object to be moved. The material of the pedestal 10 and the wheel 20 is not particularly limited, but is made of a material different from the pedestal 10 and the wheel 20 (for example, plastic for the pedestal 10 and metal for the wheel 20) so that the wheel is easy to rotate. It is desirable to do.

* Operation According to the moving aid 1, the pressure-sensitive adhesive sheet 30 is adhered to the lower four corners of the moving object 100 not provided with casters, so that the moving object not provided with such casters is provided. Can be rolled and carried (see FIG. 6). Because of the adhesiveness of the tape, it can be easily attached without damaging the moving object. In addition, it is naturally easy to remove. Therefore, moving objects without casters, such as luggage such as trunk cases,
Any other moving object having an area where the upper surface of the pedestal 10 can come into contact with the glass plate, pottery, metal plate, stone, small articles in the home, or the like can be attached and moved.

Further, in the present movement assisting tool 1, the wheels 20
Since it is a sphere provided via the bearings 12..., It is not limited to a specific direction and rotates in any direction of 360 degrees, so that the moving object 100 can be freely moved in a direction desired by the user. it can. Thus, the moving aid 1
Can be easily attached and detached as compared with the case where a conventional caster is applied. However, since it is attached to the moving object 100 based on the adhesive force, the user can expect more than the conventional moving aid. There is a high possibility that it will come off.

In order to reduce the external force as much as possible, when one wheel is used as in the case of the moving aid 1, the midpoint O of the wheel comes to the center of the base 10 as described above. With such a design, this possibility is reduced.
More specifically, referring to FIG. 3, an external force F acts in a direction opposite to the carrying direction during carrying, but as shown in FIG. , The external force F travels in the direction of the edge A of the pedestal 10, so that a rotational force with the edge A as a fulcrum is unlikely to be generated. On the other hand, as shown in FIG.
However, if it is displaced from the center of the pedestal 10, the external force F acts in a direction different from the direction of the line segment connecting the midpoint O and the edge A, so that a rotational force with the edge A as a fulcrum is generated. Easy to peel off. In the conventional caster 800 shown in FIG.
This is likely to be the case.

Next, the height of the pedestal is designed to be as low as possible to make it easier to balance.
Specifically, the degree of flattening is preferably such that the angle Θ (the angle formed by the line connecting the edge A and the center O of the wheel and the upper surface) shown in FIG. 3 is 60 degrees or less. The lower limit is such a height that the wheels can be fitted without projecting on the upper surface of the pedestal.

[Modification] The adhesive sheet 30 is attached to the entire upper surface 14 of the pedestal 10, but as shown in FIGS.
Of course, it may be provided on a part of the upper surface 14 of. This is because if the adhesive surface with the moving object 100 can be secured, it can be attached. * Attachment to a moving object can be realized by the following means in addition to the adhesive sheet.

First, although not shown, a magnet is used. this is,
This is effective particularly when the moving object is made of metal. Next, as shown in FIG. 5A, there is a suction cup 40 mounted on the pedestal 10. Thereby, it is attached to the moving object 100 by physical adsorption. This is effective for moving a flat glass plate or the like.

Further, as shown in FIG. 5B, there are needle bodies 50... Mounted on the pedestal 10. When the object to be moved is made of paper, such as a cardboard box, if the needle is inserted into the object to be moved, the needle 50 is attached to the object by engagement with the object. In the case of this needle body, although the moving body is slightly damaged, the diameter of the needle body is extremely small (about several millimeters at most), so that the damage may be almost ignored.

Further, although not shown, it is a so-called magic tape. In this case, the surface of the moving object needs to have a surface to which the magic tape is attached.
Therefore, when using such a moving aid,
It is desirable to use the magic tape attached to the moving object. Note that this magic tape also corresponds to the attachment by the engagement described in claim 1.

In the above-described moving aid 1, the wheels have a spherical shape. Alternatively, a general wheel mechanism, for example, a cylindrical wheel mechanism supported by a bearing may be used. Although the wheel 20 is configured to be held by a holding member, as shown in FIG. 7, a spherical recess 15 having a diameter smaller than the diameter of the ball 17 of the wheel is inserted into a bottom surface 15 a of the recess 15 by inserting a bearing 18. The sphere 17 serving as a wheel may be fitted into the pedestal 10 on which the second concave portion 16 is formed with the bearing 18 interposed therebetween.

The shape of the pedestal of the above-mentioned moving aid is a quadrangular pyramid, but is not particularly limited to a cone, a prism, a cylinder, and the like. * The above-mentioned moving aids were relatively small in size and used at the four corners of the lower surface of the moving object. It may be moved with a tool.

* Although the above-mentioned movement aid has one wheel, a plurality of wheels may be provided.

[0023]

As described above, according to the moving aid of the present invention, even a moving object without a caster can be rolled and carried by being attached to the moving object. The pedestal has an attachment surface attached to the bottom surface of the moving object by adhesion, magnetic attraction, physical attraction or engagement, so that the moving object can be easily attached and detached without being damaged. be able to.

Since the object to be moved is not damaged, the object to be applied is wider than in the case where a conventional caster is used, and as described above, baggage such as a trunk case, a glass plate,
It can be attached to various objects to be moved, such as pottery, metal plates, stones, and small household items, and moved. The practical value of the moving aid of the present invention having such effects is extremely high.
