Description

  The present invention relates to a protective cover that temporarily protects components mounted on an article.

  For example, in order to temporarily protect a component mounted on an article, it is effective to cover at least a part thereof with a protective cover. As this type of protective cover, one having a shape that conforms to the outer shape of the portion to be attached and having elasticity has been proposed (see Patent Document 1). The protective cover is attached to the component using its own elastic deformation, so that the protective cover is not freely detached from the component.

JP 2009-143572 A

  In the protective cover as described above, the holding force in a state where the protective cover is attached to the component is increased by increasing the elastic force. However, when the elastic force of the protective cover itself is increased, it is difficult to deform the protective cover, and it may be difficult to attach and detach the protective cover smoothly. As described above, it is difficult to adjust the holding force to the component parts in the protective cover.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a protective cover that can easily adjust the holding force to the components.

  In order to achieve the above object, the invention according to claim 1 is a protective cover for temporarily protecting a component mounted on an article, and has elasticity and covers at least a part of the component. The gist of the invention is to include a cover main body and a pressure contact member formed on the cover main body so as to be in pressure contact with the component parts.

  According to this configuration, the pressure contact member is pressed against the component due to the elasticity of the cover main body and the rubber elasticity of the pressure contact member, so that the frictional force of the pressure contact member suitably acts on the component. For this reason, it becomes possible to adjust the holding force of the protective cover without depending only on the elastic force of the cover body.

The gist of the invention according to claim 2 is that, in the protective cover according to claim 1, the press contact member is detachably attached to the cover body.
According to this configuration, for example, the holding force of the protective cover can be maintained by exchanging the pressure contact member by using attachment / detachment of the pressure contact member with respect to the cover body.

  According to a third aspect of the present invention, in the protective cover according to the second aspect, the cover body has a through hole, and the press contact member is inserted into the through hole to be attached to the cover body. The gist of the present invention is to have an insertion part.

According to this configuration, the pressure contact member can be attached to and detached from the cover body by an extremely simple operation of inserting and removing the insertion portion from the through hole.
According to a fourth aspect of the present invention, in the protective cover according to the third aspect, the insertion portion protrudes from a surface opposite to the covering surface that covers at least a part of the component in the cover body. The gist is that it is attached.

  According to this configuration, for example, by manually pulling the insertion portion protruding from the surface opposite to the covering surface, the pressure contact of the pressure contact member against the component is relaxed, or the pressure contact member is separated from the component. The cover body can be easily removed from the component parts.

  According to a fifth aspect of the present invention, in the protective cover according to any one of the first to fourth aspects, in the pressure contact member, a pressure contact portion that is pressure contacted with the component has an uneven surface. This is the gist.

According to this configuration, since the uneven surface promotes elastic deformation more than the smooth surface, the adhesion to the component is improved.
The gist of the invention described in claim 6 is that, in the protective cover according to any one of claims 1 to 5, the press contact member includes a magnetic body.

According to this configuration, the pressure contact component can be adsorbed to the component having a surface formed of a ferromagnetic material by using the magnetic force of the magnetic material.
The invention according to claim 7 is the protective cover according to any one of claims 1 to 6, wherein the cover body includes an inner layer on the component side and an outermost layer of the cover body. And the inner layer is a foam structure, and the outermost layer is a non-foam structure.

  According to this configuration, since the inner layer is a foam structure, the buffering effect is enhanced. Moreover, since the outermost layer is a non-foamed structure, a smooth surface is formed on the outer surface of the cover body. This makes it difficult for foreign matter to adhere to the outer surface and allows easy wiping even if foreign matter adheres.

  The invention according to claim 8 is the protective cover according to any one of claims 1 to 7, wherein the cover body includes a flange portion extending in a cover recess along the outer shape of the component. It is summarized as having.

  According to this configuration, the protective cover can be handled by gripping the flange portion.

Sectional drawing which shows a protective cover and a component. Sectional drawing which shows the state which attached the protective cover to the component. It is a change example of a press-contact member, Comprising: (a) is a perspective view when the press-contact member is seen from the insertion part side, (b) is a perspective view when the press-contact member is seen from the press-contact part side.

An embodiment embodying the present invention will be described in detail with reference to FIGS.
As shown in FIG. 1, the protective cover 11 is configured by attaching a pair of pressure contact members 31 formed of a rubber-based material to an elastic cover body 21. As shown in FIG. 3, the protective cover 11 protects the constituent article by covering the component 51 mounted on the article with the cover main body 21. The cover main body 21 has a cover recess 22 along the outer shape of the component 51 and a flange portion 23 extending to the cover recess 22. In the vicinity of the periphery of the cover recess 22, a through hole 22 a for attaching the pressure contact member 31 is formed.

  As shown in FIGS. 2A and 2B, the press contact member 31 is inserted into the cover main body 21 by being inserted into the press contact portion 32 serving as the main body and the through hole 22a. A fitting portion 33 is provided. The pressure contact member 31 can be attached to and detached from the cover main body 21 by the insertion portion 33. The insertion portion 33 includes an insertion portion 33 a that is inserted through the through hole 22 a and a connection portion 33 b that connects the insertion portion 33 a to the press contact portion 32. The insertion portion 33 of the present embodiment has a triangular shape in plan view, and the connecting portion 33b has a column shape. The press contact portion 32 has an uneven surface 32 a, and the uneven surface 32 a is pressed against the outer surface of the component 51. The concavo-convex surface 32a is formed with a plurality of ridges extending in a certain direction, and the cross-sectional shape of the ridges has a triangular shape in which one side is longer than the other side.

  As shown in FIG. 3, the insertion portion 33 a protrudes from the surface opposite to the covering surface 24 of the cover main body 21 that covers the component 51, so that the insertion portion 33 a can be gripped. ing. In addition, the press contact member 31 is attached in a direction in which the ridges of the concavo-convex surface 32 a extend along the circumferential direction of the cover recess 22, and the long side is shorter than that in the cross-sectional shape of each ridge. It is attached so that it may become the outer periphery side of the cover recessed part 22 with respect to the edge | side.

Next, the material of the protective cover 11 will be described.
As shown in FIG. 3, the cover body 21 has a laminated structure including an inner layer 21a on the component 51 side and an outer layer 21b. Since the inner layer 21a (innermost layer) is a foam structure, the buffering action of the cover body 21 is enhanced. The outer layer 21b (outermost layer) is a non-foamed structure, so that a smooth surface is formed on the outer surface of the cover body 21. This makes it difficult for foreign matter to adhere to the outer surface and allows easy wiping even if foreign matter adheres. Further, the inner layer 21a is configured to be softer than the outer layer 21b, so that the function of protecting the component 51 is enhanced, and the strength of the cover body 21 is also maintained by the outer layer 21b harder than the inner layer 21a.

  The foam structure is formed from a resin-based material. The non-foamed structure is formed from a resin-based material or a metal-based material. Both the foam structure and the non-foam structure are preferably formed from a resin material from the viewpoint of reducing the weight of the cover main body 21. Although it does not specifically limit as a resin-type material, As a base material, a polypropylene resin, an acrylic resin, a polycarbonate resin etc. are mentioned, for example. The thickness of each of the inner layer 21a and the outer layer 21b is preferably 1 to 15 mm, for example. Such a cover main body 21 can be easily manufactured, for example, by vacuum forming a laminated body of the inner layer 21a and the outer layer 21b.

Examples of the rubber-based material forming the pressure contact member 31 include elastomer or rubber. Such a pressure contact member 31 has rubber elasticity and is more easily deformed than the cover main body 21. A polymer blend of elastomer or rubber and resin may be used. Examples of the rubber material include EPDM (ethylene propylene diene terpolymer), EPM (ethylene / propylene rubber), SEBS (styrene / ethylene / butylene / styrene block copolymer), NBR (nitrile rubber), and the like. It is done. Such a pressure contact member 31 can be formed by, for example, injection molding, split press molding, indirect injection molding, or the like.

Next, how to use the protective cover 11 will be described.
To attach the protective cover 11 to the component 51, the cover recess 22 is aligned with the component 51 as shown in FIGS. At this time, the protective cover 11 can be aligned by gripping the flange portion 23 of the cover body 21. When the protective cover 11 is pressed toward the component 51, the pressure contact member 31 is pressed against the component 51 due to the elasticity of the cover body 21 and the rubber elasticity of the pressure contact member 31. By such pressure contact, the frictional force of the pressure contact member 31 is suitably applied to the component 51.

  Moreover, since the pressure contact part 32 has the uneven surface 32a, since elastic deformation is accelerated | stimulated, the adhesiveness to the component 51 is improved. Moreover, the ridges forming the concavo-convex surface 32a have a triangular cross section, and the long side is located on the outer peripheral side of the cover concave portion 22 with respect to the shorter side. For this reason, the movement in the direction in which the protective cover 11 is detached is preferably suppressed by the resistance of the side wall forming the short side.

  The protective cover 11 can be removed by pulling against the frictional resistance of the pressure contact portion 32. Here, in the protective cover 11 of the present embodiment, the insertion portion 33 a protrudes from the surface opposite to the covering surface 24. Therefore, by pulling the insertion portion 33a by hand, for example, the pressure contact of the pressure contact portion 32 with respect to the component 51 can be relaxed, or the pressure contact 32 can be separated from the component 51, and the cover body 21 can be removed smoothly.

  When the elastic force of the pressure contact member 31 of the protective cover 11 is reduced or the pressure contact member 31 becomes dirty, and the pressure contact member 31 needs to be replaced, the insertion portion 33 is pulled out from the through hole 22a. Then, the pressure contact member 31 is removed from the cover main body 21. Then, a separately prepared pressure contact member 31 is attached to the cover main body 21. Thus, the holding force of the protective cover 11 and the cleanliness of the pressure contact member 31 can be maintained by exchanging the pressure contact member 31 by using the attachment / detachment of the pressure contact member 31 with respect to the cover main body 21.

  Such a protective cover 11 temporarily protects the component 51, for example, in the assembly process of the component 51, or in storage or transportation of an article. For example, in the process of assembling the component 51, by attaching the protective cover 11 to the component 51 that has already been mounted, the component 51 is protected from, for example, a collision with a tool or contamination due to oil or the like. The In addition, when the article is stored or transported, the component 51 to which the protective cover 11 is attached is protected from impact and contamination. As an article | item with which the component 51 was mounted | worn, vehicles, such as a motor vehicle, a motorcycle, a bicycle, various electrical appliances, etc. are mentioned, for example. In addition, the protective cover 11 may be formed so that the whole component 51 may be covered, and in the component 51, it may be formed so that a part for which protection is calculated | required may be covered.

The effects exhibited by this embodiment will be described below.
(1) The protective cover 11 includes a cover main body 21 that has elasticity and covers the component 51, and a pressure contact member 31 that is formed of a rubber material and is provided on the cover main body 21 so as to be in pressure contact with the component 51. is doing. For this reason, the pressure contact member 31 is pressed against the component 51 by the elasticity of the cover main body 21 and the rubber elasticity of the pressure contact member 31, so that the frictional force of the pressure contact member 31 preferably acts on the component 51. . For this reason, the holding force of the protective cover 11 can be adjusted without depending only on the elastic force of the cover main body 21. Therefore, it is possible to provide the protective cover 11 that can easily adjust the holding force to the component 51.

  (2) Since the pressure contact member 31 is detachably attached to the cover main body 21, for example, the holding force of the protective cover 11 can be maintained by replacing the pressure contact member 31.

  (3) The cover body 21 has the through hole 22a, and the pressure contact member 31 has the insertion part 33. Therefore, the cover body 21 can be inserted into and removed from the through hole 22a by a very simple operation. The pressure contact member 31 can be attached to and detached from the cover main body 21.

  (4) Since the insertion portion 33 protrudes from the surface opposite to the covering surface 24, the protective cover 11 held by the component 51 can be easily removed by pulling the insertion portion 33 by hand, for example. Can be removed.

  (5) Since the uneven surface 32a formed in the press contact portion 32 is more elastically deformed than the smooth surface, the adhesion to the component 51 is enhanced. For this reason, it becomes easier to adjust the holding force of the protective cover 11.

  (6) The inner layer 21a is made of a foam structure, so that the buffering action of the cover body 21 is enhanced. And the outer surface of the cover main body 21 is made into the smooth surface because the outer layer 21b is comprised by the non-foaming structure. This makes it difficult for foreign matter to adhere to the outer surface and allows easy wiping even if foreign matter adheres.

  (7) Since the cover body 21 has the flange portion 23 extending to the cover recess 22, the protective cover 11 can be handled by gripping the flange portion 23. For example, since the protective cover 11 can be adjusted to a predetermined position by gripping the flange portion 23, it is easy to attach the protective cover 11 to the component 51.

The above embodiment may be modified as follows.
-Although the said flange part 23 is provided over the perimeter of the cover recessed part 22, you may extend in a part of periphery of the cover recessed part 22. As shown in FIG. The cover main body 21 can also be configured without providing such a flange portion 23.

  A layer formed of, for example, a non-foamed structure may be provided on the component 51 side of the inner layer 21a. Further, at least one of the inner layer 21a and the outer layer 21b may be composed of a plurality of layers. Moreover, the inner layer 21a and the outer layer 21b can also be formed using the foam structure which has a skin layer on the surface. That is, the outer layer 21b of the non-foamed structure can be formed by using the foam structure as the inner layer 21a and the skin layer as the outer layer 21b. Note that the cover main body 21 may be composed of a single layer of a foam structure or a single layer of a non-foam structure.

  The cover body 21 may be formed from a metal material. For example, the holding force to the component 51 can be adjusted by the pressure contact member 31 while suppressing the elastic force of the cover main body 21 by forming from various metal thin plates such as aluminum.

  -Although the uneven surface 32a which the press-contact part 32 has is formed from the some protruding item | line, it may be formed from a single protruding item | line. Moreover, the uneven surface 32a can also be formed from the protruding item | line which makes cross-sectional square shape, for example, as FIG. 5 (a) and FIG.5 (b) show. The uneven surface 32a can also be formed by interspersed convex portions. In addition, you may comprise the press-contact part 32 so that a smooth surface may be press-contacted to the component 51 by abbreviate | omitting the uneven surface 32a.

-The shape of the insertion part 33 can be changed suitably. For example, as shown in FIGS. 5A and 5B, the insertion portion 33a can be changed to a circular shape in plan view. Further, the cross-sectional shape of the connecting portion 33b may be a circular shape or a polygonal shape.

  The insertion portion 33 is provided with an insertion portion 33a that is inserted into the through hole 22a. The insertion portion 33a protrudes from the surface on the opposite side to the covering surface 24, but the surface on the opposite side to the covering surface 24. You may change into the insertion part press-fit in the through-hole 22a, without projecting from. Even if it is such an insertion part, a press-contact member can be provided in the cover main body 21 so that attachment or detachment is possible. Note that the insertion portion 33 of the pressure contact member 31 may be omitted, and the pressure contact member may be detachably provided on the cover body 21 by adhesion using a double-sided tape or the like.

  In the case where at least the surface (surface to be protected) of the component 51 is made of a ferromagnetic material, the pressure contact member 31 is configured using the magnetic force by containing the magnetic material in the pressure contact member 31. It can be adsorbed to the component 51. The magnetic body may be contained in the entire pressure contact member 31 or may be contained in a part of the pressure contact member 31. For example, you may form the press-contact part 32 from the magnetic sheet formed by mix | blending a magnetic body with a rubber-type material.

A protective cover may be formed by changing the pressure contact member 31 to a sheet-like pressure contact member and laminating the pressure contact member on the inner layer 21 a of the cover main body 21.
