Description

[0001]
[Industrial applications]
The present invention relates to a coin insertion type lock device used for a lock device such as a locker.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a coin insertion type lock device attached to a locker or the like generally has a coin insertion slot and a coin reception slot provided on a frame side of the locker, and a keyhole or the like for inserting a lock on a door side of the locker.
However, such a conventional lock device requires a great deal of labor and cost when the lock device is installed later on a locker or the like that has already been installed, and the installation is extremely troublesome. There were challenges.
[0003]
[Problems to be solved by the invention]
The present invention has been made in order to solve the above-mentioned conventional problems, and can be easily attached later to a rocker or the like that has been already installed. It is an object to provide a lock device.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a coin insertion lock device according to the present invention is configured as follows.
That is, the coin insertion lock device according to the present invention includes a coin catch that is pushed upward by a coin inserted from the coin insertion slot and has a downward biasing force, and is pressed by the coin catch to hold the coin. A coin holder,
A locking member in which the key inserted into the keyhole is rotated to be in a locked state while the coin is held in the coin holding portion,
An operating cam interlocking with the locking member, which abuts against a side surface of the coin held by the coin holding unit and causes the coin to drop onto a coin falling path communicating with the coin holding unit;
A coin receiving portion for receiving the dropped coin,
With
When the coin is unlocked in a state where the coin is stored in the coin receiving portion, the operating cam pushes the operating plate upward, and the coin receiving portion pivotally supported by the pushed operating plate swings to remove the coin to the outside. It is characterized by being able to protrude.
[0005]
[Action]
According to the present invention, a coin inserted from the coin insertion slot pushes a coin catch having a downward biasing force upward.
Then, the coin is pressed by the coin catch and the coin is held by the coin holding portion.
[0006]
When the coin is held in the coin holding section and the key is inserted into the keyhole and rotated to lock the coin, the operation cam comes into contact with the side of the coin held in the coin holding section, and the coin is dropped on the coin falling path. To fall.
The dropped coin can be unlocked while being received by the coin receiving portion, and when unlocked, the operating cam pushes the operating plate upward and the coin receiving portion pivotally supported by the pushed-up operating plate swings. Move to push the coin out.
[0007]
【Example】
Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
First, FIG. 1 is an overall view of a locker using a coin insertion type lock device according to the present invention. Next, FIG. 2 is an enlarged view of a key portion of the lock device according to the present invention, FIG. 3 is a plan sectional view of FIG. 2, FIG. 4 is an exploded perspective view of a coin storage case, and FIG. 6 is a sectional view taken along the line AA in FIG. 5, FIG. 7 is a schematic view showing a state when a coin is inserted, FIG. 8 is a schematic view showing a state when the coin is locked, and FIG. 9 is a key in FIG. FIG. 10 is a cross-sectional view at the time of rotation, FIG. 10 is a cross-sectional view of FIG. 8, FIG. 11 is a state diagram at the time of unlocking, and FIG.
[0008]
First, the present invention will be described with reference to FIG. In FIG. 4, reference numeral 1 denotes a lock case.
On the front side of the lock case 1, a coin insertion slot 2 and a coin exit 3 are provided.
Further, an elongated hole 4 is provided on an upper side surface of the lock case 1, and a projection 6 of a coin catch 5 is locked in the elongated hole 4 so as to be able to swing vertically.
[0009]
The coin catch 5 is attached to the upper part of the case via a spring 7 having a downward biasing force.
Furthermore, the locking piece 8 of the coin catch 5 is configured to lock the locking portion 10 of the operation plate 9 so that the coin catch 5 moves up and down and the operation plate 9 can also move up and down. I have.
[0010]
The vertical movement of the operation plate 9 is configured so that the protruding piece 12 of the operation plate 9 fits into the vertical hole 11 of the lock case 1 to guide the vertical movement of the operation plate 9.
Further, a coin receiving portion 13 is rotatably supported below the operation plate 9, and the coin receiver 13 is configured to protrude outward from the coin exit or retreat inside as the operation plate 9 moves up and down. I have.
[0011]
In FIG. 4, a space formed when the lock cases 1 and 1 on both sides are combined is formed as a coin 14 falling path 15 inserted from the coin insertion slot 2.
FIG. 2 shows an enlarged view of the key portion. In FIG. 2, a broken line indicates a locking member 17 which can be locked and unlocked by a key inserted into the keyhole 16.
[0012]
By the way, as understood from FIG. 3, the shaft 18 is rotated by the key inserted into the keyhole 16, and the locking member 17 and the operation cam 19 are integrally attached to the shaft 18, The lock member 17 and the operation cam 19 can be rotated together with the rotation of the lock member 18.
FIG. 6 shows a state before the coin 14 is inserted, that is, a state in which locking is not possible. As understood from FIG. Of the coin catch 5 and the key cannot be rotated any further.
[0013]
Therefore, locking cannot be performed unless the coin 14 is inserted.
However, when the coin 14 is inserted as shown in FIGS. 5 and 7, the coin 14 is first held by the coin holding unit 22 as understood from FIG.
When the coin 14 is held by the coin holding portion 22, the coin catch 5 having a downward biasing force is moved upward by the pressing from the coin 14, and as can be understood from FIG. Since the member 21 moves upward, the operation piece 20 of the operation cam 19 can rotate without abutting.
[0014]
When the operating piece 20 of the operating cam 19 rotates, as shown in FIG. 9, the operating piece 20 abuts against the side of the coin 14 held by the coin holding portion 22 and the coin 14 is pushed by the operating piece 20. And falls down on the coin falling path 15 by its own weight.
FIG. 10 shows this state.
[0015]
FIG. 10 is a view showing that the locked state is completed. As understood from FIG. 10, the locking member 17 is located in the horizontal direction and is in the locked state. If the key is removed in this state, the coin 14 stops in the coin receiving portion 13 in the lock case 1 and the locker or the like is locked. FIG. 8 shows this state.
Next, the unlocking operation of the lock device according to the present invention will be described. First, a key is inserted into the keyhole 16 and rotated in the direction of arrow A in FIG. Then, the operation cam 19 also rotates in the arrow A direction.
[0016]
Then, the second operation piece 23 of the operation cam 19 pushes up the cutout upper end 24 of the operation plate 9 to swing the operation plate 19 itself upward.
Then, the coin receiving portion 13 pivotally supported by the operation plate 19 rotates about the central shaft portion 25 as a rotation axis, the coin 14 moves from the position of the wavy line to the position of the solid line in FIG. 3 can be projected outside.
[0017]
Therefore, when the unlocking operation is completed, the coin 14 is protruded out of the coin exit 3, and the operator can receive the coin 14.
After the coin 14 is received, the coin catch 5 is moved downward by the spring 7 having a lower urging force.
Thereby, the operation plate 9 also moves downward, and the coin receiving portion 13 also rotates about the central shaft portion 25, and the coin receiving portion 13 is stored in the lock case 1.
[0018]
【The invention's effect】
The present invention has the above configuration.
According to the coin insertion lock device according to the present invention, the coin insertion lock device can be attached to a door of a locker or the like that has already been installed by retrofitting. Can be attached.
[0019]
Furthermore, if these are formed as an integral body, mass production becomes possible, and the cost can be further reduced.
