Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella stand lock that is used by attaching an umbrella housed in an umbrella stand to a predetermined position and attaching the umbrella stand to the umbrella stand. The key is to prevent it from being pulled out by mischief.

[0002]

2. Description of the Related Art As is well known, in a general umbrella stand lock, an umbrella storage groove is provided in a case fixed to the umbrella stand, and the umbrella is stored in the standing state and then returned to the case. For the opening / closing lever that is held in the open state by the spring, close it to store and store the umbrella, and then remove the key from the locking device attached to the opening / closing lever, and then lock this key as necessary. The umbrella can be taken out from the umbrella stand by inserting it in the door and performing an unlocking operation.

Therefore, when using the above-mentioned umbrella stand lock,
Even if the umbrella is not stored, if the open / close lever is moved to the closed state to remove the key, the key is often taken away by mischief.

Therefore, in order to solve the above-mentioned deficiencies, Japanese Patent Laid-Open Publication No. Hei 6-32651 proposes a lock for an umbrella stand, which makes it impossible to remove the key unless the umbrella is stored. The idea of this kind is that the case is equipped with a key lock cylinder lock in order to store and store the umbrella by means of an umbrella storage groove recessed in the case and an opening / closing lever pivotally attached to the case. However, in the above case, an umbrella detection unit is attached at a location such as the lower back side thereof where it is difficult to see.

With the above construction, the cylinder lock remains in the key-locked state unless the umbrella detector is pushed by storing the umbrella, so that the opening / closing lever is simply closed. The key to the cylinder lock cannot be removed just by doing.

[0006]

In the case of the above proposed umbrella stand lock, it is possible to prevent remarkably unintended removal of the key, as compared with the general umbrella stand lock described above.
However, although the above-mentioned umbrella detection part is not easily visible, if you notice this, you can push the umbrella detection part manually or push it in with something other than an umbrella, so you can remove the key. There is no hope of extinction.

In the present invention, paying attention to the above-mentioned problems, the coin which is pivotally attached to the predetermined position of the case is not attached to the case to attach the pushable umbrella detecting portion to the case. A rotary operation panel for the coin is stored, the coin is stored in the coin storage recess, and the rotary operation panel for the coin is retracted into the case, so that the cylinder lock front part provided in the case is unlocked. At the same time, the umbrella storage groove and the opening / closing lever provided in the case ensure that the umbrella is stored and stored. Then, at this time, by inserting the extracted key and releasing the cylinder lock front part, the lock is released and the cylinder lock front part is brought into the key lock state. The coin is recovered so that the coin can be collected.

The present invention appropriately introduces a new idea of using coins into the umbrella stand lock as described above, so that if the coins are not donated and housed in the case, the key is inserted. If you cannot remove the coin and want to collect this coin, you must unlock it with the key.If you unlock the coin, the key on the front of the cylinder lock will be in the key lock state, By making it impossible to pull out the key, and by doing this, if you want to mischief the key pulling out, you have to abandon the collection of coins (100 yen coins), so this kind of scandal will be effective. Trying to prevent.

[0009]

In order to achieve the above-mentioned object, the present invention has a case in which an umbrella storage groove vertically installed in the front surface of the case and a longitudinal axis are freely movable in the front-rear direction. And an open / close lever whose open state is held by an open spring and a key lock state when the open / close lever is open, and an umbrella that is vertically stored in the umbrella storage groove is in the closed state of the open / close lever. When the lock is stored in a lock with a cylinder lock installed so that the above key lock state is released and the key can be removed, the case has a coin storage recess A turning operation panel for coins that is pivotally attached so that the going-out state is held by a going-out spring, and a cam lever portion that is vertically mounted and connected to the cylinder lock front portion.
A rotating actuator engaged with a stop arm portion of the cam lever portion, which is pushed by the return spring and is given a rotational force by the rotating spring. When the turning operation panel for coins is retracted into the case, the coins in the coin storage recesses cause the turning actuator to turn against the resilience of the return spring, so that the turning arm and the turning arm are rotated. When the cam lever portion is rotated by the rotation spring due to the disengagement from the moving element, the toothed portion provided on the opening / closing lever is prevented from being opened by the opening spring of the opening / closing lever. The return retaining block that engages with the closed holding arm part having the check tooth part engraved with the internal engaging part of the coin rotating operation panel that has been pushed in to prevent the return spring from returning to the outside. An arm portion is provided, and the cylinder lock front portion is caused to rotate the cam lever portion against the rotational force by the rotation spring by the unlocking and rotating operation of the key, and the stop arm portion is operated for the rotation operation. A rotor for returning engagement, and this rotor is fitted inside and fixed to the case,
An attempt is made to provide an umbrella stand lock including a stator that is brought into a key lock state by the unlocking and rotating operation described above.

[0010]

The lock for the umbrella stand of the present invention attached to the umbrella stand is opened in a normal state so that the opening / closing lever attached to the umbrella storage groove of the case can store the umbrella in the umbrella storage groove. The coin rotation operation panel that is held in the state and pivotally mounted on the case is exposed from the cut window of the case so that the coin storage recess is in the out state. Also, the key inserted into the keyhole of the rotor in the front portion of the cylinder lock fixed to the case is, as is known as a cylinder lock of this type, in the key lock state in relation to the stater, of course, The key cannot be removed, and thus the key cannot be removed by mischief.

Next, when the umbrella is to be stored, it is not only stored in the above-mentioned umbrella storage groove, but also after storing a coin having a predetermined size such as a 100-yen coin in the coin storage recess. , By rotating the coin rotation operation panel toward the inside of the case against the elastic force of the outward spring, the coin causes the rotation actuator pivotally attached to the case to act on the pressing force of the return spring. By rotating the cam, the stopping state of the stop arm of the cam lever that has been engaged with the rotary actuator until then is released, and therefore the rotational force is applied by the rotating spring. The relevant cam lever part is
The rotation will be allowed.

As a result, the non-return tooth portion of the closed holding arm portion of the rotated cam lever portion comes into elastic contact with the base end side portion of the opening / closing lever, and at this time, the umbrella is vertically oriented in the umbrella storage groove. When the open / close lever is closed while it is stored in the, the check tooth part is locked to the tooth profile part provided on the base side of the open / close lever. The lever is prevented from opening and closing in its closed state, and the umbrella is stored and stored by the umbrella housing groove and the opening and closing lever.

Moreover, by the rotation of the cam lever portion,
Since the return-prevention arm portion will be engaged with the internal abutment portion of the coin rotating operation panel that is immersed in the case, the coin rotating operation panel containing coins is Even if you try to put this out, it will be held unrotatable,
Further, the rotor in the cylinder lock portion rotates together with the rotation of the cam lever portion, whereby the known key-releasing state is released by the relative displacement with respect to the stator, so that the umbrella stand is used. The person can pull out the key from the roller and hold it.

For this reason, even if there is a person who tries to remove the key by mischief instead of the user of the umbrella, the key can not be removed unless the 100 yen coin is abandoned. Next, the user of the umbrella can take out the umbrella from the umbrella stand by inserting the key held by the user into the key hole in the rotor of the cylinder lock front and rotating the key in a predetermined direction. As a result, the cam lever portion rotates in the direction opposite to the previous rotation direction, and at this time, the restoring force is stored in the rotation spring and the stop arm portion rotates to a predetermined position. The rotation operator rotates due to the elastic force of the return spring, the rotation operator engages with the stop arm portion, and the cam lever portion is held at the original position.

Therefore, the non-return tooth portion of the closing holding arm portion of the cam lever portion is separated from the tooth profile portion of the opening / closing lever, so that the opening / closing lever is opened by the opening spring.
The umbrella is allowed to be taken out, and the return-prevention arm of the cam lever is disengaged from the internal engaging portion of the coin turning operation panel. As a result, the turning operation panel for coins is turned back by the elastic force of the spring for going out, and the coin storage recess is exposed to the outside of the case through the window, so that the user can collect coins and use the umbrella stand. Will be completed. Of course, when the rotor of the cylinder lock portion is rotated by the key operation, the key lock state is naturally brought about, so that the key cannot be removed unless a coin is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. As will be understood from FIG. 1, a case 1 is provided with an umbrella accommodating groove 1a on its front surface in a vertical direction as well known. , Beside this umbrella storage groove 1a, the opening / closing lever 2
Is movable laterally in the front-rear direction by a vertical shaft 2a, and is pivotally mounted so as to be opened by a predetermined angle by an opening spring 2b and the opened state is maintained.

In the illustrated example, a coil spring is used as the opening spring 2b in the opening / closing lever 2, one end of which is locked to the opening / closing lever 2 and the other end of which is locked to the case 1. The base is formed in a columnar shape. A tooth-shaped portion 2c having a plurality of required teeth is engraved on an outer peripheral surface of the base portion away from the umbrella storage groove 1a, and a free end portion 2d that is convexly curved from the base portion to the front side is opened and closed. When the lever 2 is closed, as shown by a chain line, the umbrella stored between the lever 2 and the umbrella storage groove 1a is extended to a length capable of being stored.

Further, the cylinder lock front portion 3 which is also provided in the conventional example is vertically provided at the center of the rear side of the case, and 3a shown in FIG. 1 (A) is a keyhole 3b. 2 shows a rotor in a cylinder lock having a lock, and as can be understood from FIG. 2, the cylinder lock front portion 3 is internally fitted so as to be rotatable by the rotor 3a and the key K shown in FIG. , And a stator 3c to be fixed to the case 1.

In the embodiment shown in FIG. 2, the case 1 comprises an upper half portion 1A and a lower half portion 1B, and the stator 3c of the cylinder lock front portion 3 is fixed to the upper half portion 1A. At the lower end portion of the interior rotor 3a, a connecting protrusion 3d having a rectangular cross section is provided, which has a connecting screw hole 3e.
Is formed in the cam lever portion 4, which will be described later in detail, and is provided in a vertically extending through hole 4a. The connecting projection 3d is fitted and connected to the upper end opening of the cam lever portion 4 in a non-rotating state.

Further, as clearly shown in FIG. 2 and FIG. 6, a separately prepared connecting rod 4b is inserted from the lower half portion 1B of the case 1, and the through hole 4a of the cam lever portion 4 is inserted.
And the thin screw rod portion 4c at the tip of the connecting rod 4b is screwed into the connecting screw hole 3e of the rotor 3a, whereby the cam lever portion 4 is coaxially connected vertically to the cylinder lock portion 3. As a result, the rotation of the rotor 3a by the key K is transmitted to the cam lever portion 4. As is known, due to the engagement relationship between the rotor 3a and the stator 3c, the key K is in a key lock state where it cannot be removed by being inserted into the rotor 3a, and the key K rotates the rotor 3a by a predetermined angle. The cylinder lock portion 3 is configured so that the key lock state is released by performing an operation.

In the present invention, further, in the case 1 shown in the drawing, a coin turning operation panel 5 is pivotally attached to the front side of the case 1 by a lateral shaft 5a so as to be turnable in the front-rear direction. The coin turning operation panel 5 is freely retractable from the cut window 1b of the case 1 to the front side. Further, the outside spring 5b is interposed between the case 1 and the coin turning operation panel 5 so as to be held in the normal state. Therefore, at this time, the upper end side is opened. The coin storage recess 5 that will be exposed
In c, a coin C such as a 100-yen coin can be stored and held with its upper end side extended. further,
On the depth side of the coin turning operation panel 5 which is in the interior state of the case 1, an interior engaging portion 5d to be described later is provided.
Is protruding.

Further, according to the present invention, in the case shown in the drawing, the rotary actuator 6 is rotatable in the vertical direction in the case shown in FIG.
Is pivoted by a lateral shaft pin 6a, and
The downward rotation force is always applied by the elastic force of the return spring 6b that extends from the upper base end and is in contact with the ceiling wall of the case 1. Therefore, in a normal state in which the umbrella is not stored, the free end portion of the rotary actuator 6 is locked to the stop arm portion 4d projecting in the radial direction of the cam lever portion 4. As a result, the cam lever portion 4 is held in a state in which it is not allowed to rotate by the rotational force of the rotating spring 4e stretched between the cam lever portion 4 and the case 1 as clearly shown in FIG. 1B. Will be.

Reference numeral 6c in the drawing denotes a locking notch provided at the free end of the rotary actuator 6, and the stop arm 4d is locked therein so as to be disengageable. And
Further, a coin groove 6d, which will be described in detail later, is provided in the lower end edge of the rotary actuator 6 as shown in FIG. 1 (C), and a coin pressing contact parallel to the shaft pin 6 is formed. Pin 6
e is provided so as to project from the coin groove 6d.

Next, the cam lever portion 4 will be described in more detail. The above-mentioned rotary actuator 6 is provided with the above-mentioned rotary operation panel 5 for coins from the state of being out of FIG. When the coin C is stored in 5c and then pushed, when the coin C is immersed in the case 1, the coin C slides and pushes against the coin push contact pin 6e, whereby the return spring 6b. Since it rotates about the shaft pin 6a against the resilience of the above, the pushing up releases the engagement of the cam lever portion 4 with the stop arm portion 4d. In the illustrated example, the stop arm portion 4d is the shaft tube portion 4g of the cam lever portion 4.
From the upper part 4h having a large diameter.

Then, as described above, the cam lever portion 4 is allowed to rotate by the rotational force of the rotation spring 4e, but the cam lever portion 4 is radially closed from the shaft tube portion 4g of the cam lever portion 4. The portion 4i is provided in a protruding manner, and the check tooth portion 4j is provided at the tip of the portion 4i. The portion 4i is pressed against the outer peripheral surface of the base portion of the opening / closing lever 2 in the open state. By the movement, the non-return tooth portion 4j is locked to the tooth profile portion 2c, whereby the opening / closing lever 2 is restrained and held in the closed state. On this occasion,
At the lower end of the shaft tube portion 4g, the cam lever portion 4 is also provided with a backward movement preventing arm portion 4k projecting in the radial direction, which is rotated by the same cam lever portion 4 as above. Since the coin-operated operation panel 5 is rotated to come out from the cut-out window 1b to collect the coin C, it cannot be recovered because the coin operation operation panel 5 is invaded to the upper portion of the interior operation portion 5d of the operation operation panel 5.

Therefore, in order to store and take out the umbrella in the umbrella stand by using the one having the above-mentioned structure, FIG.
In the normal state of (B) and (C), of course, the rotor 3a

After storing the coin C in the coin turning operation panel 5 and then pushing the coin C into the case 1, the turning actuator 6 is turned as described above. Part 6
The stop arm portion 4d of the cam lever portion 4 is disengaged from c, whereby the rotating spring 4e rotates the shaft tube portion 4g of the cam lever portion 4.

As a result, the non-return teeth 4j of the closing holding arm 4i of the cam lever 4 elastically contacts the outer peripheral side of the base of the opening / closing lever 2, so that by closing the opening / closing lever 2 at this time, Since the tooth profile 2c provided is locked to the check tooth 4j and the opening / closing lever 2 is prevented from opening, the umbrella can be restrained and stored. At this time, by rotating the shaft tube portion 4g of the cam lever portion 4 as described above, the cylinder lock front rotor 3a having the key K rotates by a predetermined angle with respect to the stator 3c. The key lock state up to is released, and the key K can be removed as described above.

After storing the umbrella in the umbrella stand as described above, when removing the umbrella from the umbrella stand, the key K is used for the rotor 3
When the lock lever 4 is inserted into the key hole 3b of "a" and then unlocked, the cam lever portion 4 moves back, and when the stop arm portion 4d reaches the original position, the rotation actuator 6 is rotated downward by the restoring force of the return spring 6b, whereby the stop arm portion 4d is locked in the locking cutout portion 6c of the rotation operator 6.

As a result, the non-return tooth portion 4j that has been engaged with the tooth profile portion 2c is returned, so that the open / close lever 2 is released from the closed and held state and is opened by the restoring force of the opening spring 2b. However, the umbrella can be taken out from the umbrella storing groove 1a, and the rotor 3a of the cylinder lock portion 3 is returned by the return movement of the opening / closing lever 2 as described above. Cannot be removed. Therefore, as is obvious from the above-mentioned instruction, if the key K is removed by mischief, the coin C stored in the coin storage recess 5c of the coin turning operation panel 5 is abandoned. It will have to be done.
