Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein, when transporting wheels for automobiles and motorcycles in a factory or from a factory to the outside, protective tapes have conventionally been pasted to wheels, or styrene foam plates have been applied to both the ends of the wheels to be stored in a corrugated cardboard box, so that the former case requires time and labor for the pasting of the tapes, and makes the tapes unreusable, and the latter case requires preparation of packaging materials in accordance with the sizes of the wheels, resulting in a high cost due to the bulkiness of the packaging materials. <P>SOLUTION: A protective cover is formed such that a circle-like plate-form cushioning material made of polyurethane foam or the like is overlapped with a piece of cloth of approximately the same size, and a stretchable material such as rubber is provided on the outer periphery thereof in a stretchable manner, so that the protective cover is made into a bag-like shape as a whole. This enables the protective cover to be removably attached to a wheel by merely pulling the stretchable material for expansion of the opening part of the protective cover, and also the cushioning material alleviates shocks to the wheel, and prevents scars from occurring. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

    The present invention relates to a protective cover for a wheel of an automobile or a motorcycle.

  In order to prevent the wheels from being scratched when moving and transporting in-process products and finished wheels in the factory, such as automobiles and motorcycles, a protective tape has conventionally been applied to the outer surface of the wheel. Affixed or pressed on both sides of the wheel with a foamed polystyrene board and stored in a cardboard box.

  When the wheel moves to the next finishing step, the attached protective tape is peeled off or removed from the cardboard box and processed. After this processing is completed, the protective tape is applied to the wheel again and moved to the next step. The

  The finished product wheel is stored in a corrugated cardboard box with foamed polystyrene boards on both sides and transported to a car assembly plant or a store.

  As described above, the method of using the tape for protecting the wheel requires time and effort to apply or remove the tape at a predetermined position, and it is difficult to reuse the tape once used. Costs extra money and further wastes resources.

  On the other hand, the method of using a foamed polystyrene board in a cardboard box can be reused, but it takes time and effort to sandwich the wheel with the foamed foam board and put it in and out of the box, making packing and unpacking quick. I can't. In addition, various types of polystyrene sheets must be prepared for wheels of different sizes.

  An object of the present invention is to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a reusable wheel protective cover that is extremely easy to attach to and detach from wheels of different sizes.

  In order to achieve the above-mentioned object, the present invention provides a flexible plate-like cushioning material such as a urethane foam formed in a circular shape and a cloth such as a circular nonwoven fabric, which is substantially the same shape as this, and a stretchable material such as rubber on the outer periphery thereof. Is formed into a bag-like protective cover.

  The cushioning material and the fabric are overlapped and sewn or glued before fixing the elastic material, and the outer periphery of the fabric is folded inward to form a cylindrical portion, and the elastic material is placed in the cylindrical portion. The whole is formed into a bag shape by insertion.

  The protective cover of the present invention described above has a bag shape as a whole and its opening is extendable and retractable. Therefore, the cover can be easily and quickly expanded by manually expanding the bag opening. It can be put on the part or removed from the flange part. Normally, the wheels are made of metal, and if they are brought into contact with each other or other objects during moving and transportation, the wheels are damaged. In the protective cover of the present invention, the cushioning material prevents these damages.

  In addition, the protective cover does not fall out of the flange portion of the wheel unless external force is applied to the opening to stretch the elastic material, and the overall shape formed in the bag shape corresponds to that portion regardless of the size of the flange portion. Protect this.

  Furthermore, since the protective cover of the present invention has a simple configuration of a fabric, a cushioning material, and a stretchable material, it can be provided at low cost and can be used repeatedly, and resources can be used effectively.

  The opening of the protective cover is gripped and widened against the tensile force of the expansion / contraction material. The opening is hooked on the entire inner surface of the flange portion of the wheel placed horizontally on the table, and then the grip is released. Then, the opening shrinks inward by the tensile force of the elastic material, and the protective cover covers the entire flange portion. The protective cover may cover the flanges on both sides of the wheel separately, or may cover the entire wheel with a single protective cover having a deep bag-like portion.

  1 is a perspective view of the protective cover of the present invention as viewed from the opening side, FIG. 2 is a sectional view of the protective cover 1, and FIG. 3 is an enlarged sectional view of the protective cover opening. A fabric 3 such as a non-woven fabric having the same shape as this is laminated on a flexible plate-like cushioning material 2 such as a circular urethane foam having a thickness of several millimeters to several tens of millimeters, and an elastic material 4 such as rubber is provided on the outer periphery thereof. It is firmly fixed to stretch.

  When the cushioning material 2 and the fabric 3 are polymerized, both (partially or entirely) are sewn 9 or glued, so that the work of fixing the stretchable material to the outer periphery can be made accurately and easily. . If the outer peripheral portion of the fabric 3 is folded back and sewn 6 to form the cylindrical portion 5, the cushioning material 2 and the fabric 3 are superposed, and then the elastic material 4 is inserted and fixed in the cylindrical portion 5. Is formed. The length of the stretchable material 4 is such that the diameter of the protective cover 1 is half that before fixing the stretchable material 4 in a normal contracted state.

FIG. 4 is a perspective view showing a state in which the protective cover 1 of the present invention is attached to one flange portion 8 of the wheel 7 to cover the portion, and the flange portions 8 on both sides are covered with different protective covers 1 respectively. In some cases, one protective cover 1 covers the flanges 8 on both sides at the same time. The former is often used when the width of the wheel 7 is wide, and the latter is frequently used when the width of the wheel 7 is narrow. If the cloth 3 is made of a waterproof sheet such as vinyl or a vinyl sheet is provided on the inner side of the urethane foam 2, the protective cover 1 is difficult to get dirty, and even if it gets dirty, it can be easily removed.

  The protective cover 1 is attached to and detached from the flange portion 8 of the wheel 7 by pulling the elastic material 4 and enlarging the opening. The protective cover 1 attached to the flange portion 8 does not fall off the flange portion 8 due to the expansion / contraction material 4 being contracted.

  As described above, the protective cover of the present invention is a structure in which a circular plate-shaped cushioning material and a fabric are overlapped and an elastic material is provided on the outer periphery thereof. It is difficult to break and can be used repeatedly, and can be attached to and detached from wheels of different sizes.

  In addition, the protective cover can be attached to and detached from the wheel by simply pulling the elastic material to widen the opening, and the protective cover that covers the wheel reduces the impact when the wheel hits another object. Prevent scratches.
