Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain protection device for an automobile, and more particularly to a rain protection device for expanding a rain protection sheet wound around a take-up shaft so as to protrude laterally beyond a vehicle body roof.

[0002]

2. Description of the Related Art Conventionally, a car is often used on a rainy day. When getting on a car in the rain, when putting on an umbrella and opening a door close to the car, the umbrella is folded and put into a passenger compartment. When getting in and getting out of the car, open the door, lean out of the cabin, and deploy the umbrella. However, when getting on and off the car, it is difficult to fold and unfold the umbrella so that it does not get wet in the rain, and if the door is opened, rain often enters the cabin, so it gets wet considerably Often, this problem is quite serious, especially for the elderly and disabled.

[0003] In order to prevent rain from falling by means other than an umbrella when the vehicle gets on and off, various rain guards have been proposed which are detachably mounted on the vehicle. JP-A-2000-1
The rain protection device disclosed in Japanese Patent Publication No. 03238 discloses an umbrella member that is folded in a bellows shape and developed in a fan shape, a roof-side support frame portion and a door-side support frame portion fixed to both edges of the umbrella member in the developing direction, and the umbrella member can be opened and closed. A pivoting portion for pivotally supporting one end of both frame supporting portions, a biasing member for biasing the umbrella member to the closing side, a permanent magnet for attaching the roof side supporting frame portion to the roof, an attaching member for attaching the pivoting portion to the vehicle body,
It has a connecting member for connecting the door-side support frame to the door, and the umbrella member opens and closes in an arc shape in conjunction with the door.

Japanese Patent Laid-Open Publication No. 2000-108671 discloses a rain protection device shown in FIGS. 6 and 7 which includes a rain protection sheet, a winding shaft capable of winding the rain protection sheet, a storage case for rotatably supporting and storing the winding shaft. It has a permanent magnet that allows the storage case to be attached to and detached from the vehicle body, a pin joint that connects the tip of the rain protection sheet to the door, and the like. The rain protection sheet opens and closes linearly in the vehicle width direction in conjunction with the door that opens and closes. Therefore, the tip of the rain protection sheet and the door are connected via a pin joint so as to be relatively movable in the length direction of the door. .

[0005]

PROBLEM TO BE SOLVED BY THE INVENTION
In the rain protection device disclosed in Japanese Patent No. 03238, the umbrella member opens and closes in conjunction with the door. Therefore, when the umbrella member is widely opened together with the door, the umbrella member obstructs the vehicle from getting on and off the vehicle. However, since the length becomes considerably long, the structure becomes large, disadvantageous in terms of manufacturing cost, and there is a problem that the wind resistance during traveling becomes more susceptible. Also, since three parts are required to be attached to the vehicle body: the roof-side support, the door-side support, and the pivot, the attachment and detachment is quite troublesome, and the umbrella member is folded in a bellows shape,
The expansion and folding may not be performed smoothly.

In the rain protection devices of FIGS. 6 and 7 of JP-A-2000-108671, the rain-protection sheet opens and closes in conjunction with the door. Therefore, as in JP-A-2000-103238, the rain-protection sheet is enlarged together with the door. When opened, there are problems such as that the rain shield sheet hinders getting into and out of the car, and that the length of the rain shield sheet becomes considerably long, thus increasing the size of the structure.

Further, since the rain shield sheet is connected to the door, there is a possibility that the opened door may be closed by an urging force of an elastic member for urging the winding shaft in the winding direction. Also, since the rain sheet is not supported at all, there is a high possibility that the sheet is bent downward by being hit by rain, and there is a high risk of flapping due to wind, etc., and the rain sheet does not expand when the door is closed. There is also a problem that it is not possible to effectively utilize such as opening a window to block rain coming into the car without functioning.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rain protection device for a vehicle, in which the vehicle can get on and off the vehicle so as not to get wet as much as possible by rain, to make it easy to put on and take off the vehicle, and to reduce the size of the structure. And that it can be used effectively except for getting on and off the car, and that the rainproof seat be deployed in a stable state.

[0009]

According to a first aspect of the present invention, there is provided a rain protection device for a vehicle for preventing rain from raining when the vehicle gets on and off, wherein the rain protection sheet and a windable roll capable of winding the rain protection sheet. A support member for rotatably supporting the take-up shaft, a biasing member for biasing the take-up shaft in a winding direction, and a permanent magnet capable of attaching and detaching the support member to and from the vehicle body; In a state in which the member is mounted near the door of the vehicle body roof, the rain protection sheet is configured to be expandable so as to protrude laterally beyond the vehicle body roof.

In this rain protection device, the take-up shaft is rotatably supported by the support member, and the take-up shaft is urged in the winding direction by the urging member, and the rain protection sheet is taken up by the take-up shaft. With the permanent magnet, the support member can be easily attached near the door of the vehicle body roof, and in this state, the rain sheet is pulled out from the winding shaft against the urging force of the urging member, and is laterally beyond the vehicle body roof. Can be deployed to overhang. In a state where the rain protection sheet is deployed, the umbrella can be folded and unfolded as much as possible to prevent getting wet in the rain while getting on and off the car, while keeping the rain protection sheet out of the rain.

Since the opening and closing of the rain protection sheet can be performed independently without interlocking with the door, the rain protection sheet can be freely expanded regardless of the opening degree of the door. Since it is sufficient that the rain protection sheet can be developed to an appropriate size without being too large, the length of the rain protection sheet can be made relatively short. The structure of such a rain protection device can be reduced in size, which is advantageous in terms of manufacturing cost, and is hardly affected by wind resistance when the vehicle is mounted on the vehicle body, and the deployed rain protection sheet does not hinder the getting on and off of the vehicle. Since the rain guard sheet can be deployed with the door closed, it is possible to block rain coming into the vehicle even if the window is opened in this state, and it can be effectively used for purposes other than getting on and off the vehicle.

According to a second aspect of the present invention, there is provided a rain protection device for a vehicle, wherein a link mechanism for connecting the support member and a front end portion of the rain protection sheet, and a rain protection sheet deployed via the link mechanism against the urging force of the urging member. A second urging member for urging the second urging member is provided. The second urging member can reliably deploy and hold the rain guard sheet via the link mechanism. The deployed rain guard sheet can be supported by the link mechanism, so that the rain guard sheet does not receive the rain and bends largely downward, and there is no danger of the wind or the like largely flapping.

According to a third aspect of the present invention, in order to wind the rain protection sheet from a deployed state to a winding shaft,
It is characterized in that a pulling mechanism for pulling the front end of the rain protection sheet toward the support member is provided. By the pulling mechanism, the tip of the rain protection sheet is pulled toward the support member, and the rain protection sheet is wound on the winding shaft urged in the winding direction without slack.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. The automobile rain guard device of the present embodiment is a device for preventing rain that rains when getting on and off a car, and can independently open and close the rain guard sheet without interlocking with a door. FIG. 1 is a perspective view of a two-door automobile C equipped with the rain protection device 1, and FIG. 2 is a plan view of the automobile C of FIG.

As shown in FIG. 1 to FIG.
FIG. 6 shows a rain protection sheet 2, a winding shaft 3 capable of winding the rain protection sheet 2, a storage case 4 as a supporting member for rotatably supporting the winding shaft 3, and a winding shaft 3 shown in FIG.

The rain protection sheet 2 is a water-repellent rectangular cloth sheet, for example, about half the width (for example, 50 to 70 cm) of the length (for example, about 1 m20 cm) of the side door Cd.
And a length in the unfolding direction shorter than the width (for example, 30 to 50
cm), the base end of the rain protection sheet 2 is fixed to the winding shaft 3, and a stay 10 is attached to the front end of the rain protection sheet 2. The winding shaft 3 is made of a synthetic resin material, and is slightly longer than the width of the rain protection sheet 2. As shown in FIG. 8, the take-up shaft 3 is formed in a hollow shape, and the majority of the spring mounting shaft 15 and the take-up spring 5 are disposed inside the take-up shaft 3.

A spring mounting member 16 made of synthetic resin is fixed to one end of the winding shaft 3 so as to be fitted inside. One end 15a of the spring mounting shaft 15 is chamfered and inserted and fixed to the side wall 4a of the storage case 4.

The storage case 4 is made of a synthetic resin material and is formed in an elongated rectangular parallelepiped, and stores the winding shaft 3 and the rain protection sheet 2 wound on the winding shaft 3. Although not shown, a slit (not shown) longer than the width of the rain protection sheet 2 is formed in a side wall of the storage case 4 parallel to the axial direction of the winding shaft 3. 2 for storage case 4
From the storage case 4, or taken into the storage case 4.

As shown in FIG. 8, the take-up spring 5 is provided inside the hollow take-up shaft 3 and is also externally mounted on a spring mounting shaft 15 also provided inside the take-up shaft 3. One end 5 a is fixed to a spring mounting member 16 fixed to the winding shaft 3, and the other end 5 b is engaged with a forked portion 15 b of the spring mounting shaft 15. When the rain protection sheet 2 is pulled out from the state in which the rain protection sheet 2 is wound up to the maximum on the winding shaft 3, the winding spring 5 is set to a state in which a biasing force capable of winding the rain protection sheet 2 onto the winding shaft 3 is generated. Is assembled.

The permanent magnets 6 are provided, for example, at two places on the lower surface side of both ends in the longitudinal direction of the storage case 4 and are formed in a slightly thick and flexible plate shape. The permanent magnet 6 is also provided on the curved portion of the roof Cr to some extent.
Can be magnetized. For that, for example,
The permanent magnet 6 may be attached to the lower surface of the storage case 4 via a slightly harder sponge member or the like.

The link mechanism 7 is provided at the lower side of the pulled out rain protection sheet 2 symmetrically in the width direction of the rain protection sheet 2.
A pair is provided. Each link mechanism 7 has two link members 20 and 21 that are rotatably connected, and the base end of the link member 20 protrudes from the vicinity of the end of the storage case 4 in the pull-out direction of the rain protection sheet 2. The linking member 4c is rotatably connected to the connecting piece 4c, and the tip of the link member 21 is
Is connected rotatably to the vicinity of the end of a stay 21 fixed to the end of the stay 21. The lengths of the link members 20 and 21 are equal,
The interval between the connecting portions of the two link members 20 and the storage case 4 is equal to the interval between the connecting portions of the two link members 21 and the stay 10.

As shown in FIGS. 3 and 4, the total length of the link members 20 and 21 of each link mechanism 7 is longer than the length of the rain protection sheet 2 pulled out from the storage case 4 to the maximum. The connecting part of 21 is a sheet 2
Is bent toward the center in the width direction. The length of the link member 20 is shorter than half the interval between the connecting portions of the two link members 20 with the storage case 4, and as shown in FIGS. The stay 10 comes into contact with the storage case 4 so that the rain protection sheet 2 is stored in the storage case 4 to the maximum.

As shown in FIG. 7, the torsion spring 8 is provided at the connecting portion of the link members 20 and 21 of each link mechanism 7,
The rain protection sheet 2 is urged toward the developing side by urging the link members 20 and 21 toward the extending side. The link members 20 and 21 are rotatably connected to each other by a pivot pin 23. For example, a coil portion of the torsion spring 8 is provided on a shaft between the head of the pivot pin 23 and the link member 21. Sheathed, torsion spring 8
Has one end engaged with the engagement claw 21a of the link member 21, and the other end bent and extended to the back side of the link member 21 and engaged with the engagement claw 20a.

The pulling mechanism 9 is configured to pull the tip of the rain protection sheet 2 toward the storage case 4 by the string 25. The end of the cord 25 is connected to the center of the stay 10 in the longitudinal direction, and is guided downward by the guide piece 4d protruding toward the drawer side of the rain protection sheet 2 at the center of the storage case 4 in the longitudinal direction. I have. By pulling the string 25,
By pulling the tip of the rain protection sheet 2 together with the stay 10 toward the storage case 4, the rain protection sheet 2 can be wound around the winding shaft 3 from the deployed state. Note that a gripping member 26 is attached to the distal end portion of the string 25 to make it easier to grip the string 25.

The operation and effect of the rain protection device 1 will be described. The storage case 4 can be easily attached by the permanent magnet 6 to the vicinity of the door Cd of the roof Cr of the vehicle body Cb. As shown in FIGS. For example, by fixing the string 25 by sandwiching it between the vehicle body Cb and the door Cd,
This stored state is maintained.

In this state, when the string 25 is released and loosened, the urging force of the torsion spring 8 causes the link mechanism to resist the urging force of the winding spring 5 as shown in FIGS. The rain protection sheet 2 is deployed and held through the cover 7. In this state, when the string 25 is pulled by the pulling mechanism 9, the tip of the rain protection sheet 2 is pulled toward the storage case 4 side, and the rain protection sheet 2 is wound on the winding shaft 3 without loosening and stored in the storage case 4. To go.

With the rain guard sheet 2 deployed, the umbrella can be folded and unfolded as much as possible without getting wet with rain while getting on and off the automobile C while the rain guard sheet 2 keeps the rain. Since the opening and closing of the rain guard sheet 2 can be performed independently without interlocking with the door Cd, the rain guard sheet 2 can be expanded to any size regardless of the opening degree of the door Cd. Since it is sufficient that the rain protection sheet 2 can be developed to an appropriate size without being too large, the length of the rain protection sheet 2 can be set to a relatively short length.

The structure of such a rain protection device 1 can be reduced in size, which is advantageous in terms of manufacturing cost, and is hardly affected by wind resistance during running when mounted on the vehicle body Cb. Nothing in the way. Since the rain shield sheet 2 can be deployed with the door Cd closed,
In this state, even if the window is opened, the rain coming into the vehicle can be shielded, and the vehicle can be effectively used other than when the vehicle C gets on and off.

The deployed rain guard sheet 2 can be supported by the link mechanism 7 positioned below and maintained in the deployed state, whereby the rain guard sheet 2 receives the rain and bends greatly downward. There is no danger of flapping due to wind or the like. The pulling mechanism 9 can be used to pull the tip of the rain protection sheet 2 from inside the vehicle with the cord 25. The rain protection sheet 2 is stored in the storage case 2 while the vehicle is running, and the rain protection sheet 2 becomes wet before getting off the car C. Without pulling the string 25, the rain protection sheet 2 can be deployed.
