Description

[Detailed Description of the Invention] The present invention relates to a push-button lock for partitions that can be locked from the indoor side and unlocked from the outdoor side with a coin or the like.

Conventionally, there were push-button locks in which pushing in a push button attached to the inside and outside of the door caused the latch to retreat and unlock using the action of a taper formed at the end of the push button, but this was originally intended for temporary locking. Therefore, if you want to use it as a partition lock for a room that you want to lock from the inside, such as a bathroom or toilet, you need to install a separate locking mechanism, which makes the structure complicated, so it is not suitable for use in places where the purpose is to lock. It was hot.

However, the present invention provides a push-button lock that has an extremely simple structure and is capable of performing not only temporary locking but also permanent locking.The specific structure of the push-button lock of the present invention will be explained below with reference to the embodiments shown in the drawings.

That is, a latch 2 is fitted into a lock case 1 attached to a side stile A' of a sash door A so as to be retractable via a spring 3, and a latch 2 is fitted into handle cases 4 and 5 attached inside and outside the door so as to sandwich the lock case. In order to push back the rear tapered parts 21a, _21a of the gate-shaped slider 21, which is integrated with the latch 2 and is integral with the latch ₂ , the slider ₂₁ is cut in half so that the opposing parts are in conflict with each other. The push button rods 6 and 7 on the inside and outside of the door are formed with tapers 6 ₁ and 7 ₁ , respectively. The push button rods 7 on the outside are fitted so that they can slide only in the right angle direction to the lock case, and the holes ₇₄ with the stopper steps formed in the center of the outer push button rods 7 have inner push button rod 6
The push button rod 6 is fitted into a square hole ₆₃ formed in the center of the push button rod 6, so that the tip portion ₆₂ of the push button rod 7 is inserted into the outer tip portion 72 of the push button rod _7.
A rotating shaft ₉ equipped with a square shaft 91 that is rotated to a position where it abuts is fitted with a spring 8 interposed between the tip of the square shaft ₉₁ and the square hole ₆₃ . 6 has a knob 6a on the other end, and a rotating shaft 9
It is characterized by a structure in which a fitting groove ₉₂ for a coin or the like is formed on each end face.

In addition, the width of lock case 1 is the same as that of the horizontal stile of sash door A.
It is shaped so that it can be inserted into the hollow part of A' without any gaps, and it is inserted into the horizontal stile A' through the hole drilled in the vertical stile A'' until the back side of the front plate ₁₁ comes into contact with the vertical stile A''. , when the screw bearing shafts 5 ₁ , 5 ₁ of the outer handle case 5 are inserted through the side plates 1 ₂ , 1 ₂ of the lock case 1 through the mounting holes previously drilled in the side stile A', the side plates 1 ₂
An integral spring piece 1 ₃ formed near the through hole of the lock case 1 is pushed backward, and the front plate 1 ₁
The back side of the stile will be brought into close contact with stile A''.
After fixing the outer handle case 5 and lock case 1 to which the mounting plate 10 is screwed to the screw bearing shafts 5 ₁ and 5 ₁ that have passed through the back side, that is, the inside, of the horizontal stile A', While fitting the square hole 63 of the push button rod 6 of the inner handle case ₄ into which the spring 8 has been fitted in advance into the square shaft 91 of the rotating shaft ₉ protruding inward, the handle case is removed. 4 to the mounting plate 10
Installation of the main lock is completed by tightening the screws.

In addition, the inner and outer push button rods 6 and 7 have symmetrical bulges 6 ₄ , 6 ₄ , 7 ₃ , and 7 ₃ integrally formed on their bodies, and the inner handle case 4 has a constant push button rod 6 . Guide grooves 4 ₁ , 4 ₁ for the bulges 6 ₄ , 6 ₄ are formed so that they can slide within a range and rotate at a constant angle (90 degrees),
Guide grooves 5 ₂ , 5 ₂ are formed in the outer handle case 5 for bulges 7 ₃ , 7 ₃ that can only slide within a certain range. Furthermore, the rotating shaft 9 fitted into the hole in the center of the push button rod 7 has a groove ₉₃ perpendicular to the axis formed in a part of its outer circumference so that it can rotate by a certain angle (90 degrees). A pin ₇₅ fixed to a part of the push button rod 7 is fitted into the groove. Further, the rotating shaft 9 has a hole ₉₄ facing toward the axis, and a ball ₉₆ that is biased by a spring ₉₅ and protrudes outward is fitted into this hole. When the push button rod 9 is rotated to a predetermined position, it fits into the recesses 7 ₄ and 7 ₄ formed in the inner wall of the hole in the center of the push button rod 7 to perform a click motion.

In the figure, reference numeral 11 denotes a horizontal protrusion that extends rearward and is fixed to the side surface of the handle cases 4 and 5. One end of the pipe B is fitted into this protrusion, and the other end is appropriately fixed. Pipe B is used as a towel rack.

Next, in accordance with the above structure of the present invention, the specific usage, action, and effect of the push-button lock of the present invention will be explained.

That is, in the temporarily locked state shown in FIGS. 2 and 3, when either the inner or outer push button rods 6, 7 are pushed in against the restoring force of the spring 8, the tips of the push button rods 6, 7 are pushed into the fourth position. As shown in the figure, there is a discrepancy, so the pressed push button rod slides into the lock case 1 without any resistance, and the taper 6 ₁ or 7 ₁ pushes the tapered portion 2 ₁ a of the slider 2 ₁ . Since the latch 2 is moved backward, the latch 2 is disengaged from the fitting hole of the strike C on the door frame side, and the door can be opened.

In the temporarily locked state, when the knob 6a of the inner push button rod 6 is grasped and rotated 90 degrees, the tip ₆₂ will be in a position where it butts against the tip ₇₂ of the opposing push button rod 7. Since it comes to either pushbutton rod 6 or 7
Even if an attempt is made to push the latch in, this abutment makes it impossible for the push button rod to slide, resulting in a so-called locked state in which the latch cannot be moved back.

In this locked state, if you want to unlock it from the outside, insert a coin or the like into the fitting groove ₉₂ on the same end of the rotating shaft 9 fitted into the hole in the center of the outer push button rod 7, and turn it. When it is rotated, the square shaft ₉₁ integrated therewith rotates, and the inner push button rod 6 is rotated to its original unlocked position, so that the butt between the push button rods is released, and the second, The state returns to the unlockable state, that is, the temporarily locked state shown in FIG.

Thereafter, the above operation is repeated every time a locking/unlocking operation is performed.

As described above, according to the push-button lock of the present invention, in addition to the original function of the push-button lock, which is to retract the latch and lock the latch by sliding the push-button rod, the inner push-button rod can be rotated to lock the latch. Since the push button rods are fixed by butting against each other to enable permanent locking, push button locks can be used as partition locks in rooms where privacy must be protected, such as bathrooms and toilets. By using a cylinder lock as the rotating shaft that can control the rotation of the inner push button rod, it can be used as a door lock, and its range of applications is wide.

In addition, as shown in Figures 2 and 3, as a means of attaching the lock case, a means is adopted in which the front plate is brought into close contact with the end face of the door by the action of a spring piece that abuts the lock case against the screw bearing shaft. It is easy to install as there is no need to screw the plate to the end of the door, and if there is a protruding rod on the side of the handle case, it is convenient to attach a towel hanging pipe, and in addition to functioning as a bathroom lock. This has the advantage that it can also be used as a towel rack.
