The umbrella support member is provided on an outer wall, and is configured with a biasing unit that biases the umbrella support member toward the umbrella entrance / exit side of the umbrella insertion body with a constant force, and an opening is formed within a range in which the umbrella support member of the umbrella insertion body moves back and forth. It is characterized in that it is a constant pressure extrusion device of a rain umbrella storage device for vehicles in which a biasing body extending from the biasing means and an umbrella support member are connected through the opening.

(Operation) In such a structure, the rain umbrella is inserted into the umbrella insertion main body from the umbrella entrance / exit and the umbrella support member is pushed into the umbrella insertion main body against the biasing means by the rain umbrella to insert the rain umbrella. Store in the body. At this time, since the urging means urges the rain umbrella to the umbrella entrance / exit side with a constant urging force, the rain umbrella can always be easily pushed into the umbrella insertion main body with a constant force regardless of the pushing amount.

Moreover, even when the umbrella supporting member moves, the opening always faces the peripheral surface of the umbrella supporting member, and the opening for connecting the biasing means and the umbrella supporting member does not open in the umbrella insertion body. As a result, rainwater that drips or scatters from the rain umbrella that is stored in the umbrella-holding body and moisture from this rainwater will not escape to the outside of the umbrella-holding body through the opening.

Therefore, the opening 73 is provided in the moving range of the tubular piston 48 and always faces the peripheral surface of the tubular piston 48, and opens in the umbrella insertion body 16 regardless of the moving position of the tubular piston 48. There is no such thing. As a result, rainwater that drips or scatters from the rain umbrella stored in the umbrella-holding main body 16 and moisture from this rainwater will not escape to the outside of the umbrella-holding main body 16 through the opening 73.

Next, the operation of the constant pressure umbrella pushing device of the vehicle rain umbrella accommodating device having such a configuration will be described.

In such a configuration, the front door 27 is opened and the lock button 36 is slid to the left in FIG. 2A to open the lid body 41 to insert the rain umbrella into the umbrella entrance / exit 16, and at the same time, to tip the rain umbrella. Cylindrical piston 48 as an umbrella support member
It is inserted inside and brought into contact with the partition wall 50. With such an inserting operation of the rain umbrella, since the intermediate portion of the rain umbrella passes through the narrowed portion 20a of the tubular body 20 and is narrowed down, a part of the raindrops attached to the rain umbrella is squeezed out and squeezed out. Raindrops are discharged below the rear fender 10 via the drain port 46 and the drain hose 46a.

Also, after the tip of the rain umbrella comes into contact with the partition wall 50 as described above,
When the rain umbrella is pushed further inward against the spring force of the constant pressure spring 76, the air in the air chamber 54 is discharged outward through the orifice 47. At this time, the tip end portion of the engagement shaft portion 59b of the engagement pin 59 is relatively slidably displaced in the cam groove portion 64 of the multi-stage heart cam 58 toward the first flange 49 side. And the handle of the rain umbrella is the entrance of the umbrella
When the rain umbrella is stopped in the position where it is completely stored in the 28, the cylindrical piston 48 is moved by the spring force of the constant pressure spring 76.
It tries to be returned to the 38 side. However, at this time, the engaging shaft
The tip portion of 59b engages with the closest one of the plurality of step portions 66 of the cam groove portion 64, and after being guided to the crossing cam groove portion 65 corresponding to the engaged step portion 66, the step portion It exceeds 68 and engages with the rear V groove 61a of the heart-shaped convex portion 61 to stop. Since such an operation can be performed for each heart-shaped convex portion 61, the tubular piston 48 is locked at a position corresponding to the amount of the rain umbrella inserted, and the handle of the rain umbrella is stored in the umbrella entrance 28. Held in the open position.

In order to take out the rain umbrella from this state, it is sufficient to push the rain umbrella into the umbrella body 16 again. By this pushing operation, the cylindrical piston 48 is pushed inward, and the tip end portion of the engaging shaft portion 59b is caused by the action of the tip end portion of the step portion 68 and the heart-shaped convex portion 61.
It is guided to the inside of the return cam groove portion 63 without returning to the side. The pushing amount of the rain umbrella for this purpose may be a little, so after pushing the rain umbrella slightly and guiding the tip of the engaging shaft 59b into the cam groove 63, if the pushing force is removed from the rain umbrella, the cylindrical piston 48 will have a constant pressure. The umbrella 76 is displaced by the spring force of the spring 76 toward the umbrella entrance / exit 28 side. At this time, the tip end of the engaging shaft portion 59b is displaced in the cam groove portion 63 toward the step portion 67 side and, after exceeding the step portion 67, stops at the tip end portion of the groove portion 64a that is connected to the cam groove portion 64. . As a result, the handle of the rain umbrella projects slightly from the umbrella entrance / exit 28, so that the rain umbrella can be taken out easily.

In addition, since air is sucked into the air chamber 54 through the orifice 47 in accordance with such an operation, the moving speed of the cylindrical piston 48 toward the umbrella inlet / outlet 38 side is constant due to the air suction resistance of the orifice 47. Held in. Therefore, the umbrella does not suddenly jump out from the umbrella-inserted main body 28.

In the embodiment described above, the orifice 47 provided in the end wall 18a is used as the speed adjusting means for the cylindrical piston 48, but the invention is not necessarily limited to this. For example, the return speed of the cylindrical piston 48 may be made constant by using a known speed control means such as a centrifugal or pneumatic governor mechanism.

(Effects of the Invention) As described above, the present invention is housed in a cylindrical umbrella insertion body having an umbrella entrance and exit formed at one end and an end wall closed at the other end, and the umbrella insertion main body. An umbrella support member, which is provided so as to be movable back and forth in the longitudinal direction within a range according to the length of the umbrella, is closed by a tubular member whose rear end is closed, and is provided on the outer wall of the umbrella insertion main body. And a biasing means for biasing the umbrella support member toward the umbrella entrance / exit side of the umbrella insert body with a constant force, within the range of movement of the umbrella support member of the umbrella insert body and the peripheral surface of the umbrella support member. Since the opening is formed in the portion that constantly faces the urging member, and the urging member extending from the urging unit and the umbrella supporting member are connected through the opening, the following effects can be obtained.

That is, the urging means is provided outside the umbrella-inserting main body, and the urging means and the umbrella-supporting member are provided in a portion within the advance / retreat range of the umbrella-supporting member of the umbrella-inserting main body and constantly facing the peripheral surface of the umbrella-supporting member. Since an urging body extending from the urging means and the umbrella support member are connected through the opening, rainwater dripping or splashing from a rain umbrella stored in the umbrella body or this Never lose the humidity of rainwater to the outside of the umbrella body.

As a result, even if a spring made of steel or the like is used as the urging means, it is possible to prevent the urging means from rusting due to rainwater or moisture from the rain umbrella stored in the umbrella housing body.

Moreover, since rainwater that drips or scatters from the rain umbrella stored in the umbrella body and moisture from this rain water does not escape outside the umbrella body, the inner panel that forms the side wall of the vehicle body Even if it is arranged between the outer panel and the outer panel, it is also advantageous in preventing the inner surfaces of both panels from being rusted by rainwater or moisture from the rain umbrella stored in the umbrella body. Become.

Further, since the biasing means is provided outside the umbrella-inserted main body, the constant force biasing means having a complicated mechanism can be applied.

Furthermore, since the biasing means that biases with a constant force is used,
The umbrella can be easily pushed into the umbrella body with a constant force regardless of the pushing amount.
