DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella stand lock for storing coins when locking and returning the coins when unlocking.

[0002]

2. Description of the Related Art As an umbrella stand lock for storing an umbrella by locking the handle of the umbrella so that it cannot be taken out, there is a lock as shown in FIG.

This conventional umbrella stand lock has a lock body b having a U-shaped recess a through which the handle of the umbrella can be inserted vertically.
And a lockable opening / closing door c pivotally supported at one end of the lock body b and hinged to the open end side of the recess a to open and close.

[0004]

However, such a conventional lock for an umbrella stand can be used free of charge, and since the key can be freely locked and removed, the key may not be returned. There is a problem that the function as a lock is lost and cannot be used even though the lock is not broken.

In view of the above, the present invention has been made in view of such a problem of a conventional lock for an umbrella stand, and an object thereof is to provide an umbrella stand in which a key is always returned. They want to provide locks.

[0006]

According to the present invention,
Recess 4 for inserting umbrella handle and slot 2a for inserting coins
, A front end 6a protruding into the recess 4 of the main body case 1, and a pressing button 6 attached to the main body case 1 slidably back and forth. A spring 7 that is biased so as to protrude from the main body case 1; 6, the holding arm 8 is closed by moving the pushing button 6 backward, and the holding arm opening / closing mechanism for opening the holding arm 8 by moving the pushing button 6 forward, and the pushing button 6 is pushed when the pushing button 6 is pushed backward. Lock mechanism for locking, coin holding groove 13a capable of holding coins inserted from insertion slot 2a
Is provided at the upper part, a coin case 13 slidably attached to the body case 1 up and down, a spring 14 for urging the coin case 13 upward, and a path of the press button 6 when the coin case 13 is upward. The push button 6 is extended from the coin case 13 so as to protrude to prevent the push button 6 from moving to a lockable position, and to allow the push button 6 to move to the lockable position when the coin case 13 is located below. Stopper 15 and
When a coin is inserted into the coin case 13 and pushed down, the coin case stopper 16 locks the coin case 13 and keeps the coin pressed down, and the movement of the lock mechanism when the coin is unlocked is controlled by the coin case. An umbrella stand lock made up of a link mechanism 18 for transmitting to the stopper 16 to release the lock of the coin case 13.

It is preferable that a notch 6b formed diagonally at the lower rear end of the push button 6 is provided, and the push button 6 is pushed backward to move the stopper 15 further downward.

[0008]

When the coin is inserted into the slot 2a, the coin enters the coin holding groove 13a of the coin case 13 and stops with a part of the coin exposed to the outside of the main body case 1.

When the coin case 13 is pushed down by pushing the exposed portion of the coin, the coin case 13 is locked by the coin case stopper 16 and is maintained in the pushed down state. At the same time, the stopper 15 extended from the coin case 13 is lowered, and the push button 6 is slid so that it can be pushed into the main body case 1.

When the push button 6 is pressed with the handle of the umbrella, the holding arm 8 is closed by the holding arm opening / closing mechanism, and the handle of the umbrella in the recess 4 is wrapped and locked so that it cannot be removed. At the same time, the push button 6 is locked by the lock mechanism.

When the locking of the push button 6 is released, the push button 6 returns to the original position by the spring 7, so that the holding arm 8 is opened by the holding arm opening / closing mechanism. At the same time, the lock of the coin case stopper 16 is released by the link mechanism 18, so that the coin case 13 is moved upward by the spring 14, and the inserted coin projects from the insertion slot 2a and can be taken out.

A notch 6b formed diagonally at the lower rear end of the push button 6 is provided, and the stopper 15 is pushed further downward by moving the push button 6 rearward. Coin case stopper 16
Thus, it can be moved further below the locked position.

Reference numeral 1 denotes a main body case, which is composed of an upper case 2 and a lower case 3, and has a U-shaped recess 4 through which a handle of an umbrella can be inserted in a vertical direction. 2a is a slot for inserting coins, and coins having a diameter larger than a predetermined coin are
The size is such that it cannot enter the inlet 2a.

Reference numeral 5 denotes a groove for fitting a rectangular pipe (not shown) erected in the lateral direction on the umbrella stand. The lower case 3 and the rectangular pipe are fixed by screws (not shown). It has become.

Reference numeral 6 denotes a pressing button slidably attached to the main body case 1 back and forth.
The front end 6a is projected inside. The lower rear end of the push button 6 is formed diagonally as shown in FIG. 3 to form a notch 6b.

Reference numeral 7 denotes a button (front side in the figure) for pressing the push button 6
Spring.

Reference numeral 8 denotes two holding arms whose intermediate portions are pivotally supported by the main body case 1. These holding arms open and close in a substantially horizontal plane. When closed, the handle of the umbrella cannot be taken out and locked. It has become. Further, a long hole 8a is formed on the pressing button 6 side of the holding arm 8, and an opening / closing mechanism for opening and closing the holding arm 8 is formed by being engaged with the pressing button 6 by a pin 9 that vertically passes through the long hole 8a. doing. The opening / closing mechanism is not limited to this embodiment, but can be changed to a mechanism having the same function.

Reference numeral 10 denotes a lock member. In this embodiment, a cylinder lock is used.

Reference numeral 11 denotes a locking claw attached to the lower portion of the lock member 10, which engages with a locking hole 6c formed in the push button 6 when the push button 6 is pushed in to lock the push button 6. It is designed to stop.

As described above, the lock mechanism of this embodiment includes the lock member 10, the locking claw 11, and the locking hole 6c formed in the pressing button 6.

Reference numeral 12 denotes a torsion coil spring for urging the locking claw 11 toward the pressing button 6.

Numeral 13 denotes a coin case slidably mounted vertically, and a coin holding groove penetrating vertically in the center.
13a is provided. The width of the coin holding groove 13a in the longitudinal direction is such that a predetermined coin cannot pass through but a smaller diameter coin can pass. Further, a protrusion 13b is provided on the rear side surface of the coin case 13 to engage with a tip of a coin case stopper 16 described later.
Further, the coin case 13 is constantly urged upward by a spring 14. An opening 3a is provided at a position below the coin case 13 corresponding to the coin holding groove 13a of the lower case 3 to communicate with the return opening.

Reference numeral 15 denotes a stopper formed integrally with the coin case 13. The stopper 15 protrudes and retracts in the course of the push button 6, and when the stopper 15 is raised, the rear end of the push button 6

Press the tip 6a of the push button 6 with the handle of an umbrella,
When the push button 6 is pushed backward and moved, the notch 6b of the push button 6 further pushes down the stopper 15 to move the coin case 13 further downward so that coins cannot be taken out from the insertion slot 2a.

Further, when the push button 6 is pushed and pushed rearward, the latch claw 11 engages with the latch hole 6c to lock the push button 6, and at the same time, the opening and closing mechanism wraps the handle of the umbrella so as to wrap the handle. Arm 8 is closed. Locking is performed in this state, and when the key is removed, the state shown in FIGS.

When the lock member 10 is unlocked and the engagement between the locking claw 11 and the locking hole 6c is released (the state shown in FIG. 8), the pressing button 6
And protrudes forward. When the key is further turned, the link mechanism 18 rotates the coin case stopper 16 clockwise to release the engagement between the protrusion 13b of the coin case 13 and the tip of the coin case stopper 16. Then, the coin case 13 is urged by the spring 14 and moves upward, and a part of the coin is
Appears from 2a, returns to the initial state (state in FIG. 1), and is returned.
