Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balance weight for correcting the balance of an object to be balanced, which requires a balance correction, by mounting the balance weight.
The present invention relates to a balance weight that causes less lead damage even when lead or a lead alloy is used for a weight member.

[0002]

2. Description of the Related Art Conventionally, to-be-balanced objects, such as automobile wheels, washing machines, golf clubs, model airplanes, fishing reels, etc., which require a balance correction, the balance weight is attached to the object. ing. For example, a wheel of an automobile makes a circular motion around an axle shaft, but if the wheel balance is out of order, vibration occurs as the rotation speed increases. Therefore, the balancer finds a lighter part of the wheel through a balancer inspection, and attaches a necessary balance weight to this part to balance the wheel.

There are various types of balance weights of this type. For example, (1) a hook-shaped mounting bracket is provided on a rod-shaped weight and is used by being attached to a flange of a wheel of a wheel. (2) A plate-shaped plate having a predetermined weight with an adhesive (adhesive) applied to the back surface. (3) is formed in a long strip, cut into a predetermined weight, and is used to remove the weight from the release paper. There are those that are used by sticking to the corrected object.

Conventionally, such a balance weight has a weight (has a large specific gravity) instead of a volume and requires a certain degree of flexibility to easily cope with the shape of the object to be balanced. It is formed of an alloy as a main component.

[0005]

However, a balance weight formed of lead or an alloy containing lead as a main component has a risk of scattering lead damage because the surface is oxidized and corroded. For this reason, there are balance weights in which paint is applied to the weight body made of lead or an alloy containing lead as the main component. However, lead or lead alloy is easily deformed and easily scratched. Was insufficient to prevent When used for wheels, the paint will peel off even in a car wash. On the other hand, metal members other than lead, such as iron members, are not as soft as lead, so they are difficult to deform, and it is difficult to correspond to the shape of the object to be balanced. There is a risk of injury.

For example, in the case where the balance weight is attached by adhesive with an adhesive, the entire surface of the adhesive must be in contact with the shape of the object to be balanced in order to maximize the adhesive force. However, if the balance weight is not easily deformed, it becomes difficult to correspond to the shape of the object to be balanced. Also, if the balance weight is hard and hardly deformed, for example, even if the wheel is driven into the wheel, it does not deform along the diameter of the wheel R and does not fit in, so there is a possibility that the balance weight will come off after bonding, and The driving has a disadvantage that the wheel may be damaged, and is particularly problematic in the case of an aluminum wheel that is soft in terms of material.

[0007] Therefore, lead or an alloy containing lead as a main component has excellent specific gravity and a certain degree of softness, is easy to mount, and is compatible with the object to be balanced and does not damage the object to be balanced. To be effective,
It would be highly desirable to prevent lead damage.

In view of the above, the present invention provides a balance that prevents the surface from being oxidized and corroded to cause lead damage even when lead or an alloy containing lead as a main component is used as the weight body (weight). It is to provide weight.

[0009]

In order to solve the above-mentioned problems, a balance weight according to the present invention is a balance weight which is attached to an object to be balanced and which corrects the balance. Characterized by being coated in close contact.

Further, the balance weight of the present invention is a balance weight which is attached to an object to be balanced and which corrects the balance. It is characterized in that it is formed, and its simple substance or long body is closely adhered and covered with a synthetic resin film, and its back surface is coated with an adhesive and protected with release paper.

The balance weight according to the present invention is characterized in that the weight main body is formed of lead or an alloy containing lead as a main component. It is characterized in that it is larger than the weight body.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG.

In the figure, the balance weight is
It comprises a weight body 1, a synthetic resin film covering the weight body 1, an adhesive 3 applied to the back surface, and a release paper 4 for protecting the adhesive 3.

The material of the weight body 1 may be a metal other than lead, but lead and an alloy containing lead as the main component are most preferable. In the illustrated embodiment, the weight main body 1 is formed of lead, for example, one by one at a predetermined weight, or is divided by a groove cutting line 5 that can be cut at a predetermined weight.

The weight body 1 is covered with a synthetic resin film 2 in close contact therewith. This synthetic resin film 2
Is for preventing the weight main body 1 from being oxidized and corroded, so that a non-permeable and non-permeable material is preferable.
Considering the summer and winter seasons and regions, it is better to have heat resistance and cold resistance, and a hard material is preferable because it is hardly damaged. As a result, the weight main body 1 does not come into contact with the outside air, thereby preventing oxidation and corrosion.

An adhesive 3 is applied to the back surface of the weight body 1 covered with the synthetic resin film 2, which is protected by a release paper 4. When the weight bodies 1 are formed one by one with a predetermined weight, the weight bodies 1 are arranged continuously on the release paper 4 as shown in FIG.

However, when the weight body 1 is formed one by one with a predetermined weight, the balance weight is
When the balance weight having the predetermined weight is sectioned by the concave groove cutting line 5 for each predetermined weight, after cutting along the concave groove cutting line 5, the release paper 4 is peeled off, and the balance weight is corrected. Can be glued and mounted.

FIG. 3 is a perspective view showing another embodiment of the present invention, and FIG. 4 is a sectional view taken along the line BB of FIG. In this embodiment, the weight body 1 has a plurality of grooves 1a in the longitudinal direction.
Are formed in a plate-like long body, and the release paper 4 is larger than the weight body 1 by 4a, and the other components are the same as those in the above-described embodiment. The detailed description is omitted. Multiple grooves 1a
Is intended to facilitate deformation in the lateral direction. The reason why the release paper 4 is made larger than the weight body 1 by 4a is that
Is made easier by grasping this part and peeling it off. The release paper 4 may not only be enlarged over the entire length in the longitudinal direction as shown, but may be partially enlarged.

FIG. 5 is a perspective view showing still another embodiment of the present invention, FIG. 6 is a sectional view taken along the line C--C of FIG. 5, and FIG. 7 is a perspective view showing a used state. In this embodiment, a balance weight is used in which a rod-shaped weight main body 1 is attached to a rim flange portion F of a wheel W of a wheel using an attachment clip 10. The weight main body 1 is formed in a round and elongated rod shape along the cross-section R shape of the rim flange portion F, and is formed in a shape along the R diameter of the wheel W in an arc shape in the longitudinal direction thereof. An engagement groove 6 is formed substantially in the center in the width direction. This engagement groove 6
As shown in FIG. 7, the mounting clip 10 engages, and is fixed to the rim flange portion F with the engaging clip 10. Further, a concave groove 7 is formed in the lower portion of the weight main body 1 over the entire length in the longitudinal direction.
A cushioning material 8 is fitted in the rim. The tip end of the cushioning material 8 is slightly projected from the weight main body 1, and when mounted on the rim flange F, the projecting portion contacts the inner peripheral surface F <b> 1 of the rim flange F to perform a buffering action. . The weight main body 1 thus formed is covered with a synthetic resin film 2 in close contact therewith. Others are the same as the above embodiment. It should be noted that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the invention. For example, the balance weight is not limited to the above-described embodiment, and any conventionally known balance weight can be adopted.

[0020]

As described in detail above, the present invention provides
Since the weight body forming the balance weight is tightly covered with the synthetic resin film, the following effects are obtained.

(1) Since the weight main body 1 does not come into contact with the outside air (air), the surface is prevented from being oxidized and corroded. Therefore, even if the weight body is formed of lead or an alloy containing lead as the main component, the surface is not oxidized and corroded, and lead damage is not scattered. Therefore, lead or an alloy containing lead as the main component is used as the weight body. Can be used. Therefore, there is a weight (having a large specific gravity) instead of a volume, and it is possible to provide an optimum balance weight having a certain degree of flexibility that can easily cope with the shape of the object to be balanced. (2) If the back surface is coated with an adhesive, it is easy to attach the balance weight. If the release paper is larger than the weight body, it can be gripped and peeled off, so that the release paper can be easily peeled off. Become. (3) Since the surface is not oxidized, the same gloss quality is maintained and the commercial value is not reduced.
