Abstract

PROBLEM TO BE SOLVED: To remove a bag from an umbrella received in the bag for reliable collection by making a plurality of engaging plates having elasticity protrude from an outer periphery of a rotating shaft mounted in parallel to a lid and by providing a unidirectional clutch on each rotating shaft. SOLUTION: When an umbrella is inserted into an umbrella insertion hole 7, the umbrella 2 is inserted between engaging plates 9 oppositely placed at a distance, an outer face of a bag 3 covering the umbrella 2 is brought into contact with the engaging plates 9, and also the engaging plates 9 are pushed to open against its elasticity for smooth insertion. When the umbrella 2 is pulled out after it is inserted by a predetermined length, rotation of a rotation shaft 8 in a direction for drawing out the umbrella 2 is strained by a unidirectional clutch, so that only the umbrella 2 in the bag 3 is drawn out, resulting in the bag 3 removed from the umbrella 2. When the umbrella 2 is drawn out and support to the bag 3 from inside disappears, little contact remains between the bag 3 and the respective engaging plates 9. As a result, the bag 3 drops into a collection container 4 due to its own weight and is collected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing a bag for an umbrella, which facilitates the reuse of the umbrella by removing the bag covered by the umbrella to prevent water drops from falling at the exit of a building in rainy weather. It is about.

[0002]

2. Description of the Related Art Conventionally, an umbrella bag removing device of this type has been proposed in, for example, Japanese Patent Application Laid-Open No. 8-26232.

This umbrella bag removing device has a housing having an umbrella insertion hole formed in an upper surface thereof, a guide tube having one end connected to an insertion opening of the housing and the other end extending into the housing. A plurality of elastic tongue pieces formed by making radial cuts from the center of a disk made of an elastic material. It is composed by.

In the umbrella bag removing device, the umbrella stored in the bag is inserted from its tip end by pushing open the elastic tongues of the bag removing means, and the umbrella is moved to a predetermined position. Upon insertion and withdrawal, the bag covering the umbrella is left inside the guide cylinder due to friction with the elastic tongues, whereby the bag is removed from the umbrella.

[0005]

By the way, in such a conventional umbrella bag removing device, the elastic tongues are constantly pressed against the bag when the umbrella is pulled out.
Even after the umbrella is completely pulled out, the bag is held in a state of being sandwiched by the elastic tongue pieces. Therefore, the removed bag remains in the guide cylinder and is dropped from the guide cylinder into the housing by the umbrella inserted next.

However, the operation of inserting the umbrella varies depending on the operator, and depending on the contact state between the bag removed earlier and the umbrella inserted later, the bag removed earlier is completely removed from the guide tube. It is assumed that a phenomenon occurs in which the guide cylinder is not pushed out and remains in the guide cylinder.

Such a problem also causes the bag remaining in the guide tube and the bag to be inserted later to be entangled with each other and clog the guide tube.

Further, the upper end of the removed bag is held by the elastic tongue provided on the upper end of the guide cylinder and is exposed to the outside of the housing, but the bag is usually formed of a very flexible material. Therefore, it is conceivable that the exposed portion bends and hangs downward, which may cause water droplets adhering to the inside of the bag to overflow to the outer surface of the housing.

Further, in the above-mentioned publication, a pair of rollers are arranged so as to face each other with a predetermined space therebetween, and are arranged to be able to approach and separate from each other, and these are biased by springs or the like in the direction of approaching each other. It has also been proposed to insert each umbrella by pushing the rollers apart so that the rollers are pressed against a bag covered by the umbrella and the pressing force is used to remove the bag.

With this structure, a gap is created between the rollers after the umbrella is completely removed, and the bag drops into the housing due to its own weight, and it is expected to eliminate the above-mentioned problems. However, the mechanism for supporting each roller so that they can move closer to and away from each other and for elastically urging these rollers is complicated, which causes a rise in manufacturing cost.

The present invention has been made in view of the above conventional problems, and when removing a bag from an umbrella stored in the bag, the removed bag can be reliably removed in a state where the umbrella is completely removed. It is an object to be solved to provide an umbrella bag removing device having a simple mechanism for recovering the bag and removing the bag.
