Description

[Detailed description of the invention] <<Industrial application>> This invention enables the operation knob to be operated for a predetermined period of time when the numeric keypad is operated and a signal that matches the password is entered, and the lock lever is removed from the main body. This relates to a locking device for doors such as lockers that can be deviated.

<Prior Art and Problems> Conventionally, the above-mentioned locking device has a locking rod that moves up and down by rotating an operating knob (handle), a locking lever that can be freely engaged and detached from the main body by the operating knob, It consisted of a latch device that prevents the door from opening unexpectedly even when it is not locked, and an electromagnetic solenoid that allows the control knob to be operated when a signal that matches the password is entered. For this reason, the structure is complicated, the assembly work is complicated, and the cost is high.

The purpose of the present invention is to improve the above-mentioned drawbacks and provide a locking device for doors such as lockers that has a simple structure and can be manufactured at low cost.The structure is such that the locking lever is in a locked position, making the latch device inoperable. It is characterized by things.

"Example" Examples will be described below based on the drawings.

FIG. 2 shows a perspective view of a two-person locker equipped with the present invention, where reference numeral 1 indicates the main body, reference numeral 2 indicates a door provided on the front of the main body 1 via a hinge so that it can be opened and closed freely; The door shows an operation panel for inputting a password provided on the front of the door 2, numeral 22 indicates a name card holder, numeral 3 indicates a handle panel for opening and closing,
Reference numeral 31 indicates a handle window provided on the opening/closing handle panel 3, and reference numeral 5 indicates an operating knob provided on the opening/closing handle panel 3 below the handle window 31.

The door 2 rotatably holds the latch rod 6 on its back side via a latch rod holding protrusion 32 formed integrally with the opening/closing handle panel 3 and the like.

The latch rod 6 includes latch claws (not shown) provided at the upper and lower ends that engage with engagement holes (not shown) provided in the main body 1, and a handhold piece 61 facing the handle window 31. It has a rotation prevention protrusion 62 that protrudes toward the main body 1 below the handle piece 61.

The operating knob 5 has an operating lever 51 on its back end that engages with the locking lever 7, and is rotatably held within a predetermined range by an operating knob seat 8 provided on the back of the door.

That is, the operation knob 5 has a knob portion 52,
A contact portion 53 that contacts the front end surface of the operation knob seat 8
, an operating rod mounting portion 54 of the operating rod 51, and a stopper protrusion 55 projecting radially outward from the mounting portion 54.

The operating knob receiving seat 8 has a retaining fitting 81 fitted into the side wall thereof, and has fitting grooves 82, 82 for holding the operating knob 5 on the door 2, and an operating rod attaching portion 54 of the operating knob 5 to be freely rotatable. It has a holding hole 83 for holding the stopper, and a notch 84 for moving the stopper is connected to the holding hole 83 so that the operating knob 5 can be rotated within a predetermined range in correspondence with the stopper protrusion 55. There is.

After the operating knob 5 is attached to the operating knob seat 8, it is prevented from coming off and is held rotatably within a predetermined range.

The operating rod 51 has a fitting portion 5 that fits into the locking rod 7.
10 is provided at a position shifted by a predetermined distance from the extension of the portion of the operating knob 5 where the operating rod mounting portion 54 is located.

That is, if this dimension is made larger, the sliding distance of the locking rod 7, which will be described later, will be increased.

The locking rod 7 is slidably held by a locking rod holding seat 71 attached to the back side of the door 2, and when the end on the main body side engages with the locking hole 11 formed in the main body 1, the locking rod 6 A stepped portion 73 that comes into contact with the anti-rotation protrusion 62 and a fitting portion 5 of the operating rod 51
10 fits into the vertically elongated hole 74 and the operation plate 21
The plunger 91 has a locking protrusion 75 located on the electromagnetic solenoid 9 into which the plunger 91 is held for a predetermined period of time when a password is input by operating a numeric keypad provided therein.

That is, when the door 2 is closed, the locking lever 7 engages with the locking hole 11 formed in the main body 1 by rotating the operating knob 5, and at the same time, the locking protrusion 75 engages with the upper surface of the plunger 91. From, body 1
When the plunger 91 is moved to the side, the plunger 91, which is always in the protruding state, protrudes upward, and the main body 1 of the locking protrusion 75
It is located on the end face opposite to the lock hole 11.

At this time, the stepped portion 73 comes into contact with the rotation prevention protrusion 62 of the latch rod 6.

In this state, the latch lever 6 and the lock lever 7 are prevented from rotating and moving by the plunger 91, and the door 2 is locked to the main body 1 at three points. (Situation shown by imaginary lines in FIGS. 1 and 3) Next, when opening the door 2, when a password is input using the numeric keypad, the plunger 91 is retracted into the solenoid 9 for a predetermined period of time.

Then, within this time, the operating knob 5 is rotated to move the locking rod 7 to the side opposite to the main body side 1.

In this state, the locking rod 7 is removed from the locking hole 11, and the locking protrusion 75 prevents the plunger 91 from protruding upward.

At this time, the rotation prevention protrusion 62 of the latch rod 6
Then, the stepped portion 73 of the locking rod 7 comes out of contact.

That is, the latch rod 6 is rotatable, and the latch rod 6 is rotated by inserting the tip of a finger through the handle window 31 and pulling the handhold piece 61 toward you. The latch claws at the upper and lower ends of the main body 1 are disengaged from each other to open the door.

In addition, in the embodiment, the operating rod 51 and the vertically long hole 74
The rotational movement of the operating knob 5 is locked by the lever 7.
However, other methods often use
Additionally, a rotation prevention protrusion 62 of the latch rod 6 is provided on the stepped portion 73.
However, a protrusion may be provided on the locking rod 7, or an electromagnetic solenoid may be provided downward, so that the plunger normally protrudes downward under its own weight. It can be changed as appropriate without departing from the above.

<<Effects>> As described above, the present invention has a locking rod that can be freely engaged and detached from the main body by means of an operating knob, and a locking lever that abuts a part of the locking rod when the locking rod is engaged with the main body. Since the latch rod has anti-rotation protrusions that prevent the rod from rotating, the door can be locked stably at three points relative to the main body using the latch claws at the upper and lower ends of the latch rod and the lock rod. .

In addition, by making the latch rod unrotatable when locking, the locking rod, which conventionally moves up and down by rotating the operating knob, can also be used as a latch rod, which simplifies the structure and facilitates assembly. in,
Can be manufactured cheaply.
