DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle lock used for locking and unlocking a vending machine and the like.

[0002]

2. Description of the Related Art Generally, a vending machine or the like uses a handle lock as shown in FIG. The handle lock 20 is a handle case 2 attached to a door 21.
An inner case 24 is housed in the second cylindrical body 23, and a handle 26 having a cylinder lock 25 is inserted into the inner case 24.

The handle 26 is constantly urged by a compression spring 26a in a direction to protrude outward from the handle case 22, and a bar member 27 provided on a cam 25a at the rear of the cylinder lock 25 is engaged with an engagement groove 22a of the handle case 22.
And restricts the protrusion.

When unlocking the handle lock 20, a key is inserted into the cylinder lock 25, and the cam 25a is rotated to remove the bar member 27 from the engagement groove 22a, thereby causing the handle 26 to protrude from the handle case 22. At the same time, by rotating the handle 26, the engagement of the bar 24a at the rear of the inner case 24 is released.

On the other hand, when locking, the handle case 2
After the handle 26 protruding from 2 is rotated and the bar piece 24a is engaged, when the handle 26 is pushed into the handle case 22, the bar member 27 is engaged with the engagement groove 22a and the handle 26 is inserted into the handle case 22. Is stored.

[0006]

However, the above-described handle lock mechanism has a problem that incomplete lock is easily generated when locking. The cause is that if any rotational load is applied from the side of the bar 24a when the handle 26 is pushed into the handle case 22, the side surface of the handle 26 hits the inner surface of the handle case 22 while the bar 24a is not locked, and friction occurs. This is because the operator increases the force and misunderstands that the locking has been completed, and stops the locking operation here.

However, since the handle 26 is actually in an incompletely locked state stored in the handle case with the handle 26 slightly protruding from the handle case 22 due to the aforementioned frictional force, an external force such as vibration is applied and the frictional force is applied. When released, the handle 26 protrudes from the handle case 22 and is unlocked without a key.
This was unlocked without leaving any trace of the destruction, which was a serious problem from a security perspective.

In addition, a person who supplies only goods and a person who collects money are distinguished from each other based on the management request of the vending machine, and the key of the person who supplies the goods is a part which collects money. A handle lock that cannot be unlocked was desired. In other words, with the first key, the handle lock rotates only about 45 degrees, and only the product supply portion of the vending machine can be unlocked. With the second key, the handle lock rotates 90 degrees or more to unlock the money storage portion. Is what you can do. However, in the conventional configuration in which the handle lock is rotated in two stages due to the difference between the keys, there is a drawback that the handle operation when one stage is protruded is heavy and workability is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a handle lock which can be locked without being completely housed, in addition to completely housing the handle in a handle case. To provide. As a further object, the angle at which the handle can be operated by the key is different, and management according to the purpose of the operator of the vending machine can be performed.

[0010]

A handle lock according to the present invention for solving the above-mentioned problems is provided with a handle case fixed to a door side, and rotatably housed in the handle case. An inner case for operating a bar on the rear end side to lock the door to the main body, a handle in which the cylindrical body portion is engaged and housed in the inner case via a resilient spring to rotate the inner case; The cylinder lock includes a cylinder lock built into the cylinder of the handle, and a pair of bar members built into the cylinder of the handle and protruding and retracting in the radial direction of the cylinder by rotation of the cylinder lock, and a rotation angle of the cylinder lock. Controls the protrusion amount of the bar member in a plurality of stages, and the handle protrudes in a plurality of stages by an engagement groove formed in the inner surface of the handle case with which the bar member engages.

The amount of protrusion of the bar member is controlled by a cam provided at the rear end of the inner cylinder of the cylinder lock. Further, the amount of protrusion of the handle from the handle case is determined by the amount of protrusion of the bar member and the engagement groove formed on the inner surface of the handle case.

[0012]

According to the above construction, when the handle protruding from the handle case is pushed one step into the handle case, both the bar members are inserted into the first engagement grooves of the handle case in a state where the handle is not completely stored in the handle case. Inserted and locked one step. In this case, the handle is slightly projected from the handle case and can be rotated about 45 degrees, and the bar member rotates without contacting the inner periphery of the handle case, so that the handle can be operated lightly.

When the handle is further pushed into the handle case, one of the bar members moves through the elongated hole and the second bar member moves.
Is engaged with the engaging groove, and a one-side lock state is obtained. In this case, the handle is in a state of being incompletely stored in the handle case.

Therefore, when the handle is slightly protruded from the inside of the handle case, that is, when the handle is pushed into the handle case, the side surface of the handle hits the inner surface of the handle case due to the rotational load from the bar member side, and the frictional force of the handle causes the operator to use the handle. Is locked by one of the bar members 7 even if the user misunderstands.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an example of the handle lock of the present invention, FIG. 2 is an exploded sectional view of the handle lock,
3 is a front view of the handle case, FIG. 4 is a cross-sectional view of the handle case showing a state in which the inner case is housed, and FIG.
FIG. 4 is a side view of the inner case.

A handle lock 1 is fixed to the door side, an inner case 3 housed in the handle case 2, and a handle lock 1 which is housed in the handle case 2 and urged to protrude outward. Handle 4, a cylinder lock 5 attached to the handle 4, and a pair of bar members 7 disposed around the cam 6 of the cylinder lock 5 so as to face each other.
It is composed of

As shown in FIGS. 2 and 3, the handle case 2 includes a cylindrical body 2a and a mounting portion 2 orthogonal to the cylindrical body 2a.
b, the mounting portion 2b has a handle storage portion 2c, and a through hole 2d into which the inner case 3 is inserted is formed in the cylindrical body 2a.

Further, a mounting hole 2e for mounting a switch or the like for detecting whether or not the handle is completely stored is formed in a part of the handle storage portion 2c. A raised cylindrical portion 2f for waterproofing is formed around the mounting hole 2e. Further, as shown in FIGS. 2 to 4, a notch M is formed over a predetermined depth at an entrance portion on the front side upper edge of a portion where the cylindrical body 4 a of the handle 4 rotates. The notched portion M is inserted with an upper end overlay portion 4c of the handle 4, which will be described later.

On the inner surface of the cylindrical body 2a, on the inner surface of the through hole 2d, which faces the one bar member 7, there are formed engaging grooves 8 for engaging the bar members 7, respectively. And a continuous shallow groove 8a is formed in the longitudinal direction of the cylindrical body 2a. Further, the shallow groove 8a is continuous with the circumferential groove 8b formed over the entire circumference of the through hole 2d. Here, shallow groove 8a
And the circumferential groove 8b have substantially the same depth. Therefore, one bar member 7 engages with the engaging groove 8, the shallow groove 8a, and the circumferential groove 8b according to the amount of protrusion.

On the front side of the cylindrical body 2a, an engagement groove 8 'with which the other bar member 7 engages as shown by an imaginary line in FIG.
Are formed long up to the position 8-1. This engagement groove 8 'is similarly continuous with the peripheral groove 8b via the shallow groove 8'a.

The inner case 3 housed in the through hole 2d of the handle case 2 is slidably inserted around the outer periphery of the cylindrical body 4a of the handle 4, and the handle 4 is located between the handle 4 and the rear end face.
A repulsion spring 9 for urging in a direction in which the projection is projected is elastically mounted.

As shown in FIG. 5, a pair of left and right long holes 10 are formed asymmetrically on the side surface of the inner case 3.
On one side, an incomplete prevention locking step 10a-1 and a one-step locking step 10b are formed in a stepped manner. Further, a stepped portion 10c to be engaged when the bar member 7 is most retracted is formed at the front. On the other side, a step portion 10a for complete locking and a step portion 10b for single-step locking are formed in a step shape.
Here, the incomplete prevention locking step 10a-1 is formed longer than the complete locking step 10a.

The step portion 10a for complete lock, the step portion 10a-1 for incomplete prevention lock, and the step portion 10b for single-step lock engage with the bar member 7 in accordance with the amount of projection of the bar member 7. When the member 7 is most protruded, it is engaged with the complete locking step 10a of the inner case 3, and when it is retracted one step, it is engaged with the incomplete prevention locking step 10a-1 and further protruded. Then, it engages with the step portion 10b for single-stage locking.

Further, the engagement grooves 8 of the handle case 2
8 ', a pair of bar members 7 locked in the shallow groove 8a and the circumferential groove 8b are arranged in a pair facing each other so as to surround the cam 6 at the rear part of the inner cylinder 5a, and the tips open symmetrically with respect to the pin 7a. Is biased by the spring 7b.

For this reason, as shown in FIGS. 10 to 11, when the handle 4 is stored in the handle case 2, the tip of the bar member 7 protrudes from the elongated hole 10 so that the engagement groove 8 of the handle case 2, 8 to prevent the handle 4 from protruding, and the tip of the handle 4 is disengaged from the engagement grooves 8, 8 by the rotation of the cam 6 to engage with the shallow groove 8a and the circumferential groove 8b. Enables stepwise projection.

On the other hand, when the bar member 7 is located at the step 10 c of the elongated hole 10, it is completely immersed, and the handle 4 is in the state of being most protruded from the handle case 2.

The handle 4 is formed in a substantially T-shape by a cylinder 4a inserted into the cylinder 2a of the handle case 2 and a grip 4b provided orthogonal to the cylinder 4a. A cylinder lock 5 is screwed to a nut 13 fixed to a screw 13a in the body 4a.

Then, as shown in FIG. 6, the U-shaped rotation preventing member 14 is inserted into the mounting hole 14a of the cylinder 4a, and the tip thereof is brought into contact with the cutout surface 5c of the outer cylinder 5b of the cylinder lock 5, and The rotation is blocked.

Next, the operation method of the handle lock will be described.
This will be described with reference to FIGS. FIGS. 6 and 7 show a state in which the handle 4 protrudes to the maximum from the handle case 2, that is, a state in which the door can be opened by rotating the handle 4 90 degrees or more in this state.

In this case, as shown in FIG.
It is completely immersed from the outer periphery of the inner case 3. Therefore, the rotation of the handle 4 is restricted by a rotation restricting member (not shown). The rotation angle can be freely set by the rotation restricting member.

When the handle 4 is pushed one step further into the handle case 2 from this state, the bar member 7 as shown in FIGS. 8 and 9 is locked one step by the circumferential groove 8b.
In this state, the handle 4 can be rotated left and right by 45 degrees, with the upper end overlay 4c being restricted by the notch M of the handle case 2.

Next, when the handle 4 is pushed further inward from the one-stage locked state, the bar member 7 projects left and right asymmetrically. That is, the bar member 7 corresponding to the incomplete prevention locking step 10a-1 of the inner case 3 projects completely and engages with the engaging groove 8 'of the handle case 2 at the position 8-1.
For this reason, even if some rotation load is applied to the handle 4 and the side surface of the gripping portion 4b contacts the inner surface of the handle case 2 and the operator misunderstands that the operator is completely locked by the frictional force, that is, the handle 4 One of the bar members 7 is locked in the engaging groove 8 'even if it protrudes from the handle case 2. Thereby, incomplete lock can be prevented.

When the handle 4 is further pushed in, the bar member 7 is engaged with the engaging groove 8 as shown in FIGS. In this case, the handle 4 is completely stored in the handle case 2.

The operation of the one-stage lock and the complete lock can be performed in the order of the one-stage lock and the complete lock, respectively, but the one-stage lock can be omitted and the complete lock can be performed from the beginning.

Next, a case where a key is inserted into the cylinder lock 5 and unlocked from a completely locked state will be described. First, a key is inserted into the cylinder lock 5 and the cam 6 is rotated. Then, as shown in FIGS. 8 and 9, the bar member 7 retreats by one step, and engages with the circumferential groove 8b from the engaging groove 8 of the handle case 2 through the shallow groove 8a. At this time, the handle 4 protrudes to the one-stage lock position by the biasing force of the repulsion spring 9.

In this state, the handle 4 can be rotated left and right by about 45 degrees while being restricted by the notch M. At this time, the product storage door of the vending machine can be unlocked by a bar (not shown) fixed to the rear end of the handle case 2. If a key which can be rotated only to this position is set in the cylinder lock 5, the person holding this key can only supply the goods.

Further, when the cam 6 is rotated by the key, the bar member 7 is completely immersed from the outer periphery of the inner case 3. Then, the handle 4 is protruded by the urging force of the repulsion spring 9 and can freely rotate as shown in FIGS. By operating the bar fixed to the rear end of the handle case 2 in this state, the cash storage unit of the vending machine can be unlocked.
Up to this point, a person with a rotatable key can carry out the operation of storing cash in the vending machine.

The cylindrical portion 2f is provided around the mounting hole 2e of the handle case 2 and the rubber 20 is provided inside the grip portion 4b opposed to the cylindrical portion 2f. The surrounding waterproofness can be improved. In addition, even if the rubber | gum 20 is not arrange | positioned, it can fully waterproof by only the cylindrical part 2f.

[0039]

As described above, the handle lock according to the present invention comprises a handle case fixed to the door side,
An inner case that is rotatably stored in the handle case and operates a bar to lock the door to the main body at the rear end side, and a cylindrical body is engaged in the inner case via a resilient spring. A handle that is stored and rotated to rotate the inner case, a cylinder lock built in the cylinder of the handle, and a pair of cylinders that are built in the cylinder of the handle and protrude and retract in the radial direction of the cylinder by rotation of the cylinder lock. The protrusion amount of the bar member is controlled in a plurality of steps by the rotation angle of the cylinder lock, and the handle is provided in a plurality of steps by an engagement groove formed in an inner surface of a handle case with which the bar member engages. When the handle is pushed into the handle case, even if the side of the handle hits the inner surface of the handle case due to the rotational load from the bar member side and the operator misunderstands due to the friction force Tsu can click. Also, when the handle is further pushed into the handle case from this state, the handle can be completely locked, so that the two-stage lock can be performed.

When a key that can rotate the inner cylinder of the cylinder lock only about 45 degrees and a key that can rotate more than 90 degrees are set, a portion where the vending machine can be unlocked by the key is distinguished, and cash management and product Management can be done separately. Further, since the cylindrical portion and the rubber are provided around the mounting hole, the waterproof property around the switch can be improved.

Further, even when the handle is projected one step, since the bar member rotates while being restricted by the groove of the inner case without contacting the inside of the handle case, the operation can be performed extremely lightly.
