The bellows seat 300 prevents rain from entering the space between the door 100 and the front seat entrance / exit when the door 100 is opened. The bellows sheet 300 may not be provided.

The rainproof device 1 includes a curtain 2, a winding mechanism 3, and a movable support mechanism 12. The curtain 2 is provided so as to cover the upper side of the space formed between the door 100 and the front seat entrance / exit when the door 100 is opened. The curtain 2 is formed in a sheet shape with a material (polyamide fiber, polyvinyl chloride, etc.) that is impermeable to water, has water resistance, and has flexibility so that it can be wound by the winding mechanism 3. ..

As shown in FIG. 5, the curtain 2 is formed in a shape similar to a trapezoid or a fan shape. Specifically, the curtain 2 has an inner end portion 2a attached to the winding mechanism 3, an outer end portion 2b attached to the movable support mechanism 12, and a front end of the inner end portion 2a and a front end of the outer end portion 2b. It is formed in a shape surrounded by a front end portion 2c to be connected and a rear end portion 2d connecting the rear end of the inner end portion 2a and the rear end of the outer end portion 2b. The inner end portion 2a and the outer end portion 2b are linear and extend so that the distance between the inner end portion 2a and the outer end portion 2b gradually becomes narrower toward the front end side. The inner end portion 2a corresponds to the first end portion of the present invention. The outer end portion 2b corresponds to the second end portion of the present invention.

The front end portion 2c is provided at a position closer to the door rotation axis L1 than the rear end portion 2d, and is formed to have a length shorter than that of the rear end portion 2d. Further, the front end portion 2c is formed in an arc shape recessed toward the rear end portion 2d side. The radius of curvature of the front end portion 2c is determined based on the distance between the rotation axis L1 and the front end portion 2c.

The rear end portion 2d is formed in a straight line. The rear end portion 2d may be formed in an arc shape like the front end portion 2c.

The curtain 2 is provided so as to be wound up by the winding mechanism 3 when the front seat door 100 is closed and pulled out from the winding mechanism 3 when the front seat door 100 is opened. The take-up mechanism 3 is provided so that the take-up axis L2 faces the front-rear direction of the vehicle at the roof edge portion 200 located above the front seat entrance / exit. The winding mechanism 3 may be attached to the roof edge portion 200 by any method such as double-sided tape or hooking with a claw portion. The take-up axis L2 may be set parallel to the surface of the roof edge 200, or may be set parallel to the ground (that is, horizontal). Further, the winding mechanism 3 is located above the movable support mechanism 12 (see FIG. 1).

As shown in FIGS. 4, 6 and 7, the take-up mechanism 3 includes a take-up shaft 5, support portions 6 and 7, a spring 8, a transmission portion 9, and a support rod 10. Further, the winding mechanism 3 includes an opaque cover 4 (see FIGS. 1 and 2) covering the configuration in addition to the configurations shown in FIGS. 4, 6 and 7. The cover 4 prevents the inside of the winding mechanism 3 from being visually recognized from the outside. The cover 4 is formed in a long shape in the direction of the take-up axis L2, and the outlet 4a of the curtain 2 is formed on the side surface on the door 100 side. The cover 4 is attached to the roof edge 200.

The take-up shaft 5 has a take-up axis L2 as a central axis, has a circular ring-shaped cross section when cut in a plane orthogonal to the take-up axis L2, and is from one end side along the axis L2. It is formed in a tapered shape that gradually shrinks in diameter toward the other end. The small diameter side end 5a (see FIG. 7) of the take-up shaft 5 is located in the front (the side of the rotation axis L1 of the door 100), and the large diameter side end 5b (see FIG. 7) is located in the rear. Further, the take-up shaft 5 is formed in a tubular shape having a space inside. By forming the take-up shaft 5 in a tapered shape in this way, as shown in FIG. 5, the take-up shaft 5 is taken up in a form in which slack is suppressed with respect to the curtain 2 whose width gradually increases toward the rear end portion 2d. It can be wound around the shaft 5.

Both ends 5a and 5b of the take-up shaft 5 are rotatably supported around the axis L2 by the support portions 6 and 7.

An inner end portion 2a (see FIG. 5) of the curtain 2 is attached to the take-up shaft 5. The take-up shaft 5 rotates as the outer end portion 2b of the curtain 2 attached to the movable support mechanism 12 moves as the door 100 opens and closes. As a result, the take-up shaft 5 winds the curtain 2 from the side of the inner end 2a as the door 100 closes, while the take-up shaft 5 winds the curtain 2 from the side of the outer end 2b (see FIG. 5) as the door 100 opens. Pull out from. The winding direction of the curtain 2 on the winding shaft 5 is determined so that the curtain 2 is pulled out from the lower side of the winding shaft 5, as shown in FIG. According to this, the difference in height between the drawer position of the curtain 2 and the movable support mechanism 12 can be reduced. As a result, the upper end of the drawer opening 4a of the cover 4 can be brought close to the movable support mechanism 12, and it is possible to prevent the inside of the winding mechanism 3 from being visible from the drawer opening 4a when the curtain 2 of FIG. 1 is stored.

The support portions 6 and 7 are attached to the bottom surface portion (not shown) of the cover 4, respectively, and are provided so as to stand up from the bottom surface portion. One support portion 6 rotatably supports the small-diameter end portion 5a of the take-up shaft 5 around the axis L2, and also supports one end of the support rod 10. The other support portion 7 rotatably supports the large-diameter end portion 5b of the take-up shaft 5 around the axis L2, and also supports the other end of the support rod 10 and one end of the spring 8.

The spring 8 is a coil spring in which a linear metal member is spirally formed. The spring 8 is provided inside the take-up shaft 5 in a state of being inserted into the support rod 10. One end of the spring 8 is fixed to the support portion 7, and the other end is fixed to the transmission portion 9. The spring 8 is configured as a torsion coil spring, that is, a spring that accumulates elastic energy by receiving a torsional load and generates a spring force that tries to rotate the spring 8 around the axis by the elastic energy. The spring 8 is provided so that a spring force acts on the take-up shaft 5 in the direction in which the curtain 2 is taken up.

The transmission unit 9 is a component for transmitting a force between the take-up shaft 5 and the spring 8. The transmission portion 9 is provided inside the take-up shaft 5 in a state of being inserted into the support rod 10. The transmission portion 9 is provided so that the end portion of the spring 8 on the side opposite to the side fixed to the support portion 7 is fixed and the spring 8 cannot move relative to the inner wall portion of the take-up shaft 5 around the axis L2. Has been done.

The support rod 10 is a component for supporting the spring 8 and the transmission portion 9. The support rod 10 is provided inside the take-up shaft 5 so that the axis of the support rod 10 coincides with the take-up axis L2. Both ends of the support rod 10 are supported by the support portions 6 and 7.

The operation of the winding mechanism 3 will be described. When the curtain 2 is pulled out (when the door 100 is opened), the take-up shaft 5 rotates with the pulling out of the curtain 2, and this rotational force is transmitted to the spring 8 via the transmission unit 9, and the spring 8 receives Elastic energy to wind up the curtain 2 is accumulated. The spring force due to this elastic energy acts on the take-up shaft 5 and the curtain 2 via the transmission portion 9, and the curtain 2 is pulled in the direction of the take-up mechanism 3. As a result, the curtain 2 is deployed in a stretched state regardless of the opening state of the door 100 (see FIG. 2). On the other hand, when the door 100 is closed, the spring force of the spring 8 acts on the take-up shaft 5 via the transmission portion 9, so that the take-up shaft 5 rotates, and this rotation causes the curtain 2 to take up the take-up shaft 5. It is taken up by.

As shown in FIGS. 1 and 2, the movable support mechanism 12 is attached to the outer surface side of the upper end portion 102c of the door 100. The movable support mechanism 12 may be attached to the door 100 by any method such as double-sided tape or hooking with a claw.

As shown in FIGS. 4 and 8, the movable support mechanism 12 includes a fixing plate 13, two pins 14 and 15, a movable plate 16, and a spring 19. Note that in FIG. 8, the spring 19 is not shown. In addition to the configurations shown in FIGS. 4 and 8, the movable support mechanism 12 includes an opaque cover 20 (see FIGS. 1 and 2) that covers this configuration. The cover 20 hides the configurations of FIGS. 4 and 8 from the outside. The cover 20 is attached to the upper end 102c of the door 100 or to the fixing plate 13 by, for example, a claw.

As shown in FIG. 8, the fixing plate 13 is formed in the shape of an elongated rectangular plate. The longitudinal width of the fixing plate 13 is set to be equal to or shorter than the longitudinal width of the upper end 102c of the door 100. The width in the lateral direction of the fixing plate 13 is set to be equal to or slightly shorter than the width in the lateral direction of the upper end portion 102c. That is, the fixing plate 13 is formed so as not to protrude from the upper end portion 102c.

The fixing plate 13 is fixed to the outer surface of the upper end 102c of the door 100 with double-sided tape or the like. At this time, the longitudinal direction of the fixing plate 13 faces the longitudinal direction of the upper end 102c (that is, the front-rear direction), and the lateral direction of the fixing plate 13 faces the lateral direction of the upper end 102c (that is, the vertical direction). In other words, the center line L3 (see FIG. 8) extending in the longitudinal direction of the fixing plate 13 is fixed so as to coincide with or be parallel to the center line L7 (see FIG. 9) extending in the longitudinal direction of the upper end 102c. The plate 13 is attached to the upper end 102c.

Two through holes 13a and 13b are formed in the fixing plate 13. These through holes 13a and 13b are formed at intervals in the longitudinal direction of the fixing plate 13. Specifically, the through holes 13a and 13b are formed, for example, on the longitudinal center line L3 of the fixing plate 13. One of the through holes 13a is formed in front of the center line L4 extending in the lateral direction of the fixing plate 13 (the side closer to the door rotation axis L1). The other through hole 13b is formed behind the center line L4 in the lateral direction.

Pins 14 and 15 are inserted through the through holes 13a and 13b, respectively. That is, the pins 14 and 15 are fixed to the fixing plate 13. Further, the pins 14 and 15 are fitted in the guide grooves 17 and 18 formed in the movable plate 16. The tips of the pins 14 and 15 are formed to have a diameter larger than the width in the lateral direction of the guide grooves 17 and 18, so that the pins 14 and 15 cannot be pulled out from the guide grooves 17 and 18. Further, the pins 14 and 15 are provided so as to be movable along the longitudinal direction of the guide grooves 17 and 18.

The movable plate 16 is formed in the shape of an elongated rectangular plate like the fixed plate 13. The longitudinal width of the movable plate 16 is set to be equal to or shorter than the longitudinal width of the fixed plate 13. The width in the lateral direction of the movable plate 16 is set to be equal to or shorter than the width in the lateral direction of the fixed plate 13. The outer end portion 2b of the curtain 2 is attached to the movable plate 16 in a state of being arranged on the movable plate 16 along the longitudinal direction of the movable plate 16.

The movable plate 16 is attached to the fixed plate 13 so as to be movable on the outer surface of the fixed plate 13 in a predetermined locus at a position facing the outer surface of the fixed plate 13. Specifically, two guide grooves 17 and 18 are formed in the movable plate 16, and the movable plate 16 is placed on the surface of the fixed plate 13 by fitting the pins 14 and 15 into the guide grooves 17 and 18. It is attached so that it can be moved according to the guide grooves 17 and 18. At this time, the longitudinal direction of the movable plate 16 is oriented in the same direction as the longitudinal direction of the fixed plate 13, and the lateral direction of the movable plate 16 is oriented in the same direction as the lateral direction of the fixed plate 13.

The guide grooves 17 and 18 have the movable plate 16 and the outer end portion 2b of the curtain 2 attached to the movable plate 16 in the in-plane direction of the outer surface of the fixing plate 13 (in other words, the outer surface of the door upper end portion 102c) as the door 100 is opened and closed. It is a groove for moving in a predetermined locus in the in-plane direction of the door. The guide grooves 17 and 18 are formed so as to penetrate the movable plate 16.

As shown in FIG. 9, the first guide groove 17 is formed in front of the center line L6 extending in the lateral direction of the movable plate 16 (door rotation axis L1 side). In other words, the first guide groove 17 is formed at a position closer to the front end portion 16a of the movable plate 16 than the second guide groove 18. The second guide groove 18 is formed behind the center line L6 in the lateral direction. In other words, the second guide groove 18 is formed at a position closer to the rear end portion 16b of the movable plate 16 than the first guide groove 17. The guide grooves 17 and 18 are formed symmetrically with respect to the lateral center line L6 at a position equidistant from the lateral center line L6 of the movable plate 16, for example.

Further, the guide grooves 17 and 18 extend in an oblique direction with respect to the center line L5 extending in the longitudinal direction of the movable plate 16. Specifically, the first guide groove 17 is linear and extends so as to gradually approach the lower end portion 16c of the movable plate 16 in the direction of the front end portion 16a of the movable plate 16. The longitudinal center point of the first guide groove 17 is located, for example, on the longitudinal center line L5 of the movable plate 16.

The second guide groove 18 is linear and extends so as to gradually approach the lower end portion 16c of the movable plate 16 toward the rear end portion 16b of the movable plate 16. The longitudinal center point of the second guide groove 18 is located, for example, on the longitudinal center line L5 of the movable plate 16.

In this way, the guide grooves 17 and 18 are extended in different directions, and specifically, they are formed so as to form a C shape when viewed from the direction of FIG.

The lengths (longitudinal widths) of the guide grooves 17 and 18 are set to the same length, but may be set to different lengths. The longer the guide grooves 17 and 18, the larger the amount of movement of the movable plate 16 when the door 100 is opened and closed, and the larger the amount of pulling of the curtain 2. The lengths of the guide grooves 17 and 18 are set so that the curtain 2 does not loosen. Further, the lengths of the guide grooves 17 and 18 are such that when the curtain 2 is opened to the maximum (when the door 100 is fully opened), the pins 14 and 15 come into contact with the rear ends 17b and 18b of the guide grooves 17 and 18. When the curtain 2 is retracted (when the door 100 is completely closed) when the rear ends 17b and 18b are approached (see the upper view of FIG. 10), the pins 14 and 15 are the guide grooves 17 and 18. It is determined so as to come into contact with the front end portions 17a and 18a or close to the front end portions 17a and 18a (see the lower part of FIG. 10).

Further, the larger the inclination of the guide grooves 17 and 18 with respect to the longitudinal center line L5 of the movable plate 16, the larger the amount of movement of the movable plate 16 in the vertical direction when opening and closing the door 100, while increasing the amount of movement in the front-rear direction. The amount of movement becomes smaller. The inclinations of the guide grooves 17 and 18 are determined so as not to protrude from the fixing plate 13 or the door upper end 102c when the movable plate 16 moves.

In the movable plate 16, when the pins 14 and 15 are in the middle positions of the guide grooves 17 and 18, the longitudinal center line L5 of the movable plate 16 and the longitudinal center line L7 of the upper end 102c of the door 100 are parallel to each other. (See the middle diagram of FIG. 10). In the middle view of FIG. 10, when the pins 14 and 15 are located at the center positions of the guide grooves 17 and 18 in the longitudinal direction, the longitudinal center line L5 of the movable plate 16 and the longitudinal center of the upper end portion 102c of the door 100 An example is shown in which the line L7 is provided so as to coincide with the line L7.

After all, the movable plate 16 moves from the position of the alternate long and short dash line in FIG. 9 to the position of the broken line when the door 100 is opened, and the position of the broken line in FIG. 9 when the door 100 is closed. It is provided so as to move from the position of the solid line to the position of the alternate long and short dash line. At this time, the movement locus of the movable plate 16 becomes a curved line. In FIG. 9, the movement locus at the center point of the movable plate 16 is indicated by reference numeral 150.

The spring 19 shown in FIG. 4 is configured as a coil spring that generates a spring force in the axial direction, one end of which is attached to the movable plate 16 and the other end of which is attached to the fixed plate 13 or the upper end 102c of the vehicle door 100. In the present embodiment, the spring 19 is provided behind the movable plate 16 and is attached to the rear end portion 16b of the movable plate 16, but is attached to the front end portion 16a of the movable plate 16 in front of the movable plate 16. May be.

The spring 19 is provided so as to apply a spring force to the movable plate 16 in the rear direction (direction away from the door rotation axis L1). Specifically, the spring 19 is provided in a state of being slightly extended from the natural length in a state where the door 100 in the lower part of FIG. 10 is closed (a state in which the movable plate 16 is located at the rearmost position). That is, the spring 19 is provided in a state where a force for moving the movable plate 16 to the rear is applied in the state shown in the lower part of FIG. Even in the states of the middle and upper views of FIG. 10, the spring 19 applies a force for moving the movable plate 16 to the rear. As described above, regardless of the position of the movable plate 16, the movable plate 16 is subjected to the rearward spring force of the spring 19.

When the spring 19 is provided in front of the movable plate 16, the spring 19 is provided in a state of being compressed rather than its natural length.

The fixing plate 13 corresponds to the fixing member of the present invention. The movable plate 16 corresponds to the movable member of the present invention. The guide groove 17 corresponds to the first guide groove of the present invention, and the guide groove 18 corresponds to the second guide groove of the present invention. The pins 14 and 15 correspond to the fitting portion of the present invention, the pin 14 corresponds to the first fitting portion of the present invention, and the pin 15 corresponds to the second fitting portion of the present invention. The spring 19 corresponds to the force applying portion of the present invention.

The above is the configuration of the rainproof device 1. Next, the action and effect of the rainproof device 1 will be described. When the door 100 is closed, the movable plate 16 of the movable support mechanism 12 is in the state shown in the lower part of FIG. That is, the movable plate 16 is in a state of being slightly tilted rearward with respect to the center line L7 of the door upper end portion 102c. When the door 100 is opened from this state, the curtain 2 is pulled out from the winding mechanism 3 as the door 100 is opened, and the pins 14 and 15 move forward along the guide grooves 17 and 18, so that the movable plate is movable. 16 moves forward against the spring force of the spring 19. When the door 100 is opened to the maximum (the curtain 2 is pulled out to the maximum), the movable plate 16 is slightly tilted forward with respect to the center line L7 of the door upper end 102c as shown in the upper part of FIG. It will be in a state of being.

As described above, from the closing of the door to the opening of the door, the movable plate 16 gradually lowers the front end portion 16a of the movable plate 16 while moving the locus of the lower view → middle view → upper view of FIG. 10, that is, the movable plate 16 forward. On the other hand, the rear end portion 16b of the movable plate 16 is moved in a trajectory that gradually moves upward. By moving the movable plate 16 in this way, the curtain 2 can be unfolded without slack. As a result, it is possible to prevent the occupant from getting wet in the rain when getting on and off the vehicle. Further, by making the rear end portion 2d of the curtain 2 linear as shown in FIG. 5, it is possible to prevent the rear end portion 2d from bending when the curtain 2 is unfolded. As a result, it is possible to prevent the rain incident on the upper surface of the curtain 2 from flowing backward and being applied to the occupants.

On the other hand, when the door 100 is closed from the state shown in the upper part of FIG. 10, the curtain 2 is wound by the winding mechanism 3 as the door 100 is closed. In addition, the movable plate 16 moves rearward along the guide grooves 17 and 18 due to the spring force of the spring 19, and finally the state shown in the lower part of FIG. 10 is obtained. As described above, from the opening of the door to the closing of the door, the movable plate 16 gradually moves upward from the front end portion 16a of the movable plate 16 while moving the locus of the upper view → middle view → lower view of FIG. On the other hand, the rear end portion 16b of the movable plate 16 is moved in a trajectory that gradually moves downward. By moving the movable plate 16 in this way, the curtain 2 can be stored in the winding mechanism 3 without any slack.

That is, when the curtain 2 is stored with the movable plate 16 fixed at the position shown in the upper part of FIG. 10, the door rotation axis L1 and the take-up axis L2 are in a twisted positional relationship, so that the rear end side of the curtain 2 is stored. Loosening occurs in the part 2e (see the lower part of FIG. 10). Since this portion 2e is a portion that can be seen from the outlet 4a (see FIGS. 1 and 2) of the winding mechanism 3, if the portion 2e is loosened, the appearance becomes poor.

In the present embodiment, the movable plate 16 moves rearward from the state shown in the upper part of FIG. 10 to the state shown in the lower part, so that the portion 2e can be pulled backward and the portion 2e is slackened. Can be suppressed. In particular, the movement locus of the movable plate 16 is curved, and the pulling direction of the portion 2e when closing the door 100 is rearward and diagonally downward with respect to the center line L7 of the portion 102c (upper end of the door) where the movable support mechanism 12 is attached. By doing so, the amount of tension with respect to the portion 2e can be increased within the range of the portion 102c. As a result, it is possible to suppress the occurrence of slack in the portion 2e and to move the movable plate 16 within the range of the upper end portion 102c of the door. Since the curtain 2 can be stored without slack, the appearance at the time of storage can be improved.

Further, since the movable plate 16 is subjected to a rearward force by the spring 19, the movable plate 16 can be reliably moved to the rear when the door 100 is closed.

Further, the movable plate 16 is formed with two linear guide grooves 17 and 18 having different inclinations at intervals in the longitudinal direction of the movable plate 16, so that the movable plate 16 can be attached to the surface of the fixing plate 13. It can be provided so as to be movable on a curved locus above.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the description of the scope of claims. For example, in the above embodiment, an example in which the movable support mechanism is attached to the door side and the take-up mechanism is attached to the vehicle body side has been described, but conversely, the take-up mechanism is attached to the door side and the movable support mechanism is attached to the vehicle body side. It may be attached.

Further, in the above embodiment, an example is shown in which a guide groove is formed on the movable plate side of the movable support mechanism and the pin is fixed on the fixed plate side, but on the contrary, the pin is fixed on the movable plate side and the fixed plate is fixed. A guide groove may be formed on the side.

Further, in the above embodiment, the guide groove formed in the movable plate is extended in a straight line, but it may be extended in a curved shape (for example, an arc shape).

Further, in the above embodiment, the coil spring is shown as a force applying portion for applying a backward elastic force to the movable plate, but an elastic member such as rubber may be used.

Further, in the above embodiment, an example in which the movement locus of the movable plate is a curved line has been described, but if a movement amount sufficient to eliminate the slack of the curtain can be secured, the movable plate is provided so as to move in a straight line locus. You may.

Further, in the above embodiment, an example in which the rainproof device is attached to the front door of the vehicle is shown, but it may be attached to the rear door of the vehicle, or a moving body other than the vehicle (vehicle in an amusement park, etc.). It may be attached to a ship or the like, or it may be attached to an object other than a moving body (for example, a vending machine). In this case, it is preferable to attach the rainproof device of the present invention to the door portion in which the door rotation axis and the take-up axis have a twisted positional relationship, such as the front seat door of a vehicle.
