Description

The present invention relates to a protective cover for covering an upper part of an automobile body during parking and a winding device for the protective cover.

Currently, there are many cases of parking in outdoor parking lots, and in such cases, the car body and the interior of the car become hot under the hot weather in summer, so not only the paint on the car body discolors or the paint has a bad hold, Immediately after driving, the engine is exposed to unbearable heat.
In the severe cold season, steam, snow, etc. in the atmosphere freeze on the windshield and rear glass, and it takes time and effort to remove them. As a countermeasure for this, a cover that covers an automobile is useful, and an application has been filed regarding a cover that covers various automobiles and a device for winding and storing the cover.

  For example, Patent Document 1 discloses an invention in which the power of a mainspring spring is used for the winding force of a cover that covers an automobile, and the winding device is mainly housed in a rear spoiler. In Patent Document 2, an automobile is disclosed. An invention is disclosed in which a winding force of a cover covering the coil is incorporated into a winding shaft, the winding device is housed in a storage box, and is mainly installed in a parking lot.

However, in Patent Document 1, since the winding force is the force of the mainspring spring, the entire thickness of the winding device cannot be made smaller than the outer diameter of the mainspring spring, and only by the width of the mainspring spring. The width of the winding device must be long.
In addition, since the vehicle body outline is mostly composed of curved surfaces, it is desirable to consider that the vehicle body outline is curved when the winder is attached to the vehicle body. However, since the winding shaft of the conventional winding device is a straight rod, the winding device inevitably protrudes, and there is a lack of practicality.

  Moreover, in patent document 2, it is not necessary to consider that this vehicle body is bent from the relationship of installing in a parking lot, but it cannot be used at any time.

  Furthermore, the conventional inventions including both patent documents are based on the premise that the winding is completely performed, and no specific measures have been taken when the winding is malfunctioning or incomplete.

An object of the present invention is to make it possible to cope with the bending of the outer shape of the vehicle body on which the winding device is installed while reducing the thickness and width of the entire winding device .

A further object of the present invention is to prevent the winding from becoming unsatisfactory during winding of the cover, and to enable complete winding even if the winding becomes unsuccessful at the end of winding of the cover or during winding. There is .

In order to solve the above-mentioned problems, the present invention relates to the thickness and width of a winding device using a metal wire that incorporates a metal wire at both ends in the vehicle length direction of the cover sheet and has the effect of a winding spring that hangs on the metal wire. And a structure that enables rotation at the central portion of the take-up shaft so that the take-up shaft can be rotated even if the outer shape of the vehicle body is curved .

Furthermore, by making the shape of the helical spring that winds up the cover into a truncated cone, it is possible to prevent the overlapping of both end portions of the seat during winding, and a folding crank type winding mechanism inside the shaft end It was built in and pulled out as needed to allow easy winding .

  As a cover, it has the effects of sun protection, dirt prevention and anti-icing, but also has the following effects.

  It is possible to reduce the thickness and width of the winding device by incorporating metal wires at both ends of the cover sheet in the longitudinal direction of the vehicle body and using metal wires that have the effect of winding springs on the metal wires. became.

  Since it became possible to reduce the thickness and width of the winding device, it was possible to incorporate it into a bumper.

  Since the structure that enables rotation at the center of the take-up shaft so that the take-up shaft can be rotated even if the outer shape of the vehicle body is bent, the take-up device can be installed easily without protruding. Can now.

  Furthermore, because the shape of the helical spring that winds up the cover is a truncated cone, it has been possible to prevent the overlapping of both ends of the sheet during winding, so that the winding failure caused by the overlapping of the cover can be prevented. Can be prevented.

In addition, a foldable crank type winding mechanism is incorporated inside the shaft end, and it can be pulled out easily when necessary, so that it is possible not only to deal with winding problems but also to ensure complete winding. The cover can be stored in the state of removal.

FIG. 1 shows an embodiment when the cover 10 and the winding device 20 of the present invention are used in an automobile.
In the case of an RV vehicle having a bumper that also serves as a step at the rear part of the vehicle body as in the embodiment, the take-up device has a sucker (not shown), a tape such as a magic tape (registered trademark), and an appropriate fixture. (It is not shown in the figure.) It is only necessary to place it on the bumper so that it can be attached and detached. In a vehicle body that does not have space for placing the winding device, the winding device has a suction cup (not shown) and a permanent magnet with a detachable mechanism ( It may be attached to the vehicle body (not shown) or attached to a rear bumper by attaching an appropriate fixing tool (not shown).
It can also be incorporated into a bumper if it meets legal regulations.

  FIG. 2 shows an internal mechanism of the cover 10 and the winding device 20. As a matter of course, this internal mechanism is housed in a predetermined housing (not shown) as necessary.

  The cover 10 includes a sheet 11, a metal wire 15 or 17 incorporated at both ends of the sheet, and a latching hole 13, and a mandrel 18 having high bending rigidity is incorporated at the leading end of the sheet as necessary.

The sheet material is a sheet made of synthetic resin film, thin cloth, non-woven fabric, etc. Especially, the non-woven fabric processed with synthetic resin from one side is non-woven fabric on the other side, and this surface is friction with the car body. It is suitable for this application because it has a small force, it is difficult to damage the car body coating, and it is easy to wrap and cover a metal wire in a bag shape.
Further, the sheet may be provided over the entire length of the metal wires 15 and 17, but may be limited to a necessary portion as shown in FIG.

The metal wires 15 and 17 are made of a material with a diameter of about 1 mm to 3 mm, such as copper alloy, steel, stainless steel, etc., which has spring properties. Rubber and synthetic materials are used as necessary to prevent damage to the car body paint. Covered with resin or the like. Here, the metal wire 15 forms a helical spring having the same diameter, and the metal wire 17 forms a helical cone-shaped helical spring. One kind of helical spring is adopted.
In addition, although a circular shape is generally used as the cross-sectional shape of the metal wire, a rectangular shape having a high torsional rigidity is also used to make it easier to hold the shape of the helical spring.
The hooking hole 13 is hooked to a vehicle pulling hook, a front bumper or the like, but an appropriate hooking hook (not shown) may be provided instead of the hooking hole.

The winding shaft includes a winding end member 25 or 27 and an intermediate shaft 29, and the winding shaft end is rotatably supported by a support member 35 or 37.
Although only one support member 35 or 37 is shown in the drawing, a plurality of support members 35 or 37 may be provided.
The shaft center line of the winding end member and the intermediate shaft is made not to be a straight line so that it can correspond to the curved vehicle body outline, but in this case the intermediate shaft is synthesized as shown in the figure A material made of resin pipe material with a protruding ring whose diameter is increased in a node shape in some places can be used easily, and a pin mechanism as shown in a foldable crank type winding mechanism 40 described later or an axle of an automobile. A simple structure (not shown) may be provided.

  The end of the metal wire 15 or 17 is fixed to the winding end member 25 or 27, and when the cover 10 is extended as the cover 10, the metal wire is sequentially drawn out. At the time of winding, when the latching hole 13 is released from the latch, the cover is wound and stored by the action of the helical spring of the metal wire. At this time, since the metal wire becomes a helical spring and does not overlap like the mainspring spring, the thickness (diameter) after winding is also a small thickness (diameter) about the winding thickness (diameter) of the sheet. Will be enough.

  Further, in the case of the metal wire 17 adopting a cone-shaped conical spring, the coil spring is wound around the conical-conical winding end member 27. It is possible to prevent the overlapping of the parts from rising greatly, and to reduce the situation of the winding failure due to the overlapping of the covers.

FIG. 3 shows a folding crank type winding mechanism 40 incorporated in the shaft end of the winding end member 25 or 27. A state in which the winding mechanism is pulled out from the shaft end is indicated by a chain line.
The crank member 41, the crank member 43, and the crank member 43 and the crank member 45 are connected by a pin 47 to form a pin connection, and a crank mechanism is formed by bending as shown in the figure.
For simplification, the crank member 43 and the crank member 45 may be a single member.
Further, the folding crank type winding mechanism is locked so as not to protrude from the shaft end by a spring-type protrusion or the like (not shown) when not in use while being pushed into the shaft end.

As a matter of course, the casing of the winding device 20 has a mechanism that prevents rain from entering, prevents intrusion of dust (not shown), and allows the cover 10 to be easily drawn out and retracted. Adopted (not shown).

  Since the present invention relates to the automobile industry with a large production volume, the degree of use in daily life is high and the industrial applicability is extremely high.

The parts used in the production of the present invention are not only in the metal industry but also in the petroleum product industry, and thus contribute greatly to the development of the industry, and can be used in many industrial fields. Is expensive.
