Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door locking device for a partition provided on the door of an indoor partition or a bathroom, a toilet, etc.

[Conventional technology]

Conventionally, this type of door locking device has a structure in which a temporary locking latch bolt is released by manually rotating a knob. That is, a substantially semicircular cam is fitted to a square shaft connected to each knob on the outside and inside of the room, and this cam is fitted into an opening of a sliding member connected to the rear end of a latch bolt, and this cam rotates together with the knob. When the latch bolt is moved, one end of the cam engages the sliding member and retracts the latch bolt in the release direction.

[Problem that the invention attempts to solve]

For locks that release the latch bolt by turning a knob, the knob may be too large to turn, especially if a young child turns the knob by hand. The downside is that you can't turn the knob even when it's wet or your hands are slippery with soap.

The present invention aims to solve this problem and provides a partition door that is provided with a push button for unlocking a temporary locking latch bolt on the indoor side and the outdoor side of the door.

[Means for solving problems]

The purpose of the present invention is to provide an outdoor escutsion and an indoor escution that are fixed to the outdoor and indoor surfaces of a door, respectively, and an outdoor push button that is inserted into through holes provided in the outdoor and indoor escutches, respectively. and an indoor push button, a sliding frame connected to a latch bolt that is retractably provided at the end of the door and biased in a direction to project from the end of the door by a spring, and has an opening, and a protrusion at one end. an outside cam which is provided with a protruding part at one end and a locking part at the other end, and which is pivotally connected to a pin provided on the outdoor escutcheon; an inside cam pivotally connected to a pin provided on the indoor escutcheon, a protruding part of the outside cam abutting the outdoor push button, and a locking part of the outside cam inserted into the opening. At the same time, the protruding part of the inside cam was brought into contact with the indoor push button, and the locking part of the inside cam was inserted between the locking part of the outside cam and the opening.

[Effect]

When one of the indoor and outdoor push buttons provided on the indoor and outdoor sides is pushed, for example, when the indoor push button is pushed, the inside cam that is in contact with the indoor push button rotates about the pin and locks the latch bolt. One end of the sliding frame connected to the latch bolt is pushed while resisting the biased spring, so the latch bolt retreats in the release direction. Furthermore, when the other outdoor push button is pushed, the outside cam rotates and pushes the sliding frame, so the latch bolt connected to the sliding frame resists the spring that biases the latch bolt. while moving backward in the direction of release.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

In the figure, FIG. 1 is a longitudinal sectional view of the partition door locking device of the present invention showing the locked state of the latch bolt.
FIG. 2 is a longitudinal sectional view of the partition door locking device of the present invention showing the latch bolt in an unlocked state.

In FIG. 1, numerals 1 and 2 are an outdoor escutcheon fixed to the outdoor surface of the door 3, and an indoor escutcheon fixed to the indoor surface.

A through hole 1a is formed in the escutcheon 1 on the outdoor side of the door 3, and a slidable outdoor push button 4 that can be pushed with a finger is inserted into the through hole 1a, and both ends are fixed to the escutcheon 1 on the outdoor side. An outside cam 6 is pivotally attached to the middle part of the pin 5, and a protrusion 6c provided at one end of the outside cam 6 is brought into contact with the flange 4a of the outdoor push button 4, and the other end of the outside cam 6 is The locking portion 6a provided at the latch bolt 7 is inserted into the opening 8a of a slidable sliding frame 8 connected to the rear end of the latch bolt 7. The inside cam 9 is pivotally connected to the middle part of the pin 10 whose both ends are fixed to the indoor escutcheon 2, and the protrusion 9c provided at one end of the inside cam 9 is connected to the flange 11 of the indoor push button 11.
a, and the locking portion 9b provided at the other end of the inside cam 9 is brought into contact with the groove 6 provided in the locking portion 6a.
b and the end 8b of the opening 8a, and when the indoor push button 11 is pushed with a finger, the inside cam 9 rotates about the pin 10 and the inside cam 9 is engaged. The stop portion 9b is located at the end 8 of the sliding frame 8.
b to move the latch bolt 7 backward in the release direction while resisting the spring 12 that biases the latch bolt 7. Furthermore, when the outdoor push button 4 is pushed with a finger, the outside cam 6 and the inside cam 9 move together to press the end 8b of the sliding frame 8 against the spring 12 that biases the latch bolt 7. While doing so, move the latch bolt 7 back in the releasing direction (see Fig. 2).

In order to prevent the release from the outdoor side, a rotatable stopper member 14 provided on the indoor escutcheon 2 is pivotally attached with a pin 13, so that the bulging portion 14a of this stopper member 14 is connected to the inside cam 9. When it comes into contact with the protrusion 9a formed in the front, the indoor/outside push buttons 11, 4 cannot be pressed and become locked.

In addition, when an unexpected accident occurs in the bathroom, there are times when it is necessary to perform an emergency release operation from the outdoor side. small hole 1
5 matches the position of the stopper member 14, and in case of an emergency, insert the wire 16 into this small hole 15 and insert the stopper member 14 into the tip 16a of the wire 16.
When pressed with the pin 1, this stopper member 14
3 around the support shaft, and the bulging portion 1 of the stopper member 14 is
4a comes off from the protrusion 9a of the inside cam 9,
The indoor/outside push buttons 11, 4 can be pressed and the latch bolt 7 can be moved back in the release direction.

Reference numeral 17 is a handle formed integrally with the indoor and outer escutcheons 1 and 2, 18 is a fixing member for the indoor and outer escutches 1 and 2, and 19 is a leaf spring that biases the stopper member 14.

[Effect of idea]

As described above, the present invention has an indoor/outside push button on the inside and outside of the door, and since these push buttons are pushed into the door, the release operation can be performed reliably without the hand slipping, resulting in excellent operability. It is something that plays.
