Description

Detailed Description of the Invention The invention of this application is loosely inserted into a tubular case installed in a door, and an opening/closing mechanism and a locking mechanism are linked to a slider that has a latch bolt that also serves as a lock bolt at its tip. The invention relates to a dual-purpose lock structure, in particular a spring that presses and biases a lock cam pivotally supported on the tubular case, and a lock interposed between the lock cam and the tubular case. The mating portion allows switching within the flip-flop, and the locking portion of the slider can be brought into contact with the locking portion to regulate the stroke of the slider and perform a locking action, thus allowing various types of locking operations. The present invention relates to a dual-purpose lock structure in which a part is linked to the lock cam to act as a locking mechanism, and a dual-purpose lock structure in which a lever set opening/closing mechanism is linked to the locking mechanism to provide a one-touch type.

Conventionally, when a lock is required to have a locking function as a lock embedded in a door, etc., a lock with a latch bolt and a regular lock with a dead bolt are each installed separately. , which were operated separately and independently, but when installed together, a large amount of buried space was required, and it was difficult to drill holes for the door mounting part. , the lock operation parts such as key cylinders are each separate and independent transmission systems, making it unprecedented.
Since it is connected to the main lock, it is difficult to add a linking structure between the locking operation and the handle operation, and therefore it has an essential drawback that it is impossible to improve the prudence of the locking operation.

To deal with this, recently the above-mentioned blank lock and full lock have been integrated, and the opening/closing mechanism has been improved in operability by adding a locking push button, lock knob, etc. to the center of the rotary knob. Various improvements have been made.

However, a device that combines the functions of Kuzen and this lock has the disadvantage that the mechanism inside the case is complicated, and the case cannot be made compact, resulting in high costs, difficulty in manufacturing work, and There are various disadvantages in terms of drilling holes for installation on the door, etc., and when adding a linking function between the operating part such as the handle and the locking operation part, the mechanism becomes even more complicated, which is an inconvenience that exacerbates the above disadvantages. It had

Furthermore, it goes without saying that the complexity of the above-mentioned mechanism is due to the addition of a locking mechanism, and the locking mechanism itself has a complicated structure. This is considered to be a bottleneck in the complicated design of the dual-purpose lock, and it has long been desired to devise a dual-purpose lock structure that has a locking mechanism with a simpler structure.

In view of the problems of the dual-purpose lock structure based on the above-mentioned prior art, the invention of this application includes: a lock cam pivotally supported on a tubular case; a spring that presses and biases the lock cam; and a spring interposed between the lock cam and the casing. The locking mechanism can be simplified by the structure in which the locking operation part is connected to the locking cam, and the locking part can be switched in a flip-flop manner by the locking part and can be brought into contact with the locking part of the slider. , it is made more compact and eliminates the above-mentioned drawbacks, solves the difficulties, and eliminates the disadvantages, and the operating part of the locking mechanism can be made into various forms, and the opening/closing mechanism using a lever and the above-mentioned locking mechanism It is an object of the present invention to provide an excellent dual-purpose lock structure that can be linked to form a one-touch lock.

In accordance with the above-mentioned object, the invention of this application has a structure in which a slider having a latch bolt at its tip which also serves as a deadbolt when locking is loosely inserted into the tubular case, and during normal use, the slider is operated by an operating mechanism linked to the slider. The sliding operation of the slider is performed, and when the lock is locked, the stroke of the slider is restricted by the locking mechanism linked to this and the slider is in the locked state. By operating the lock cam, which is pressed and biased and switched in a flip-flop manner by a retaining part interposed between the two, by an opening/closing mechanism connected to the lock cam, the locking part of the slider and the locking part of the slider are operated. A contact position or a non-contact position is selected, thereby enabling locking and unlocking, and depending on the mode of the locking operation section,
The unlocking operation is performed by a rotating knob from one side of the door and a cylinder key is used from the other side, or the locking operation is performed by a rotating knob from the side and a locking indication is displayed from the other side. This can be confirmed by a mechanism, and furthermore, the locking is performed by pressing a push button, and the normal door opening operation is performed using a lever as an opening/closing mechanism attached to the push button. The gist is that the lock is unlocked and that the lever on the opposite side cannot be used to open the lock.

Next, embodiments of the invention of this application will be described below based on the drawings.

In the embodiment shown in FIG. 1, reference numeral 1 denotes a dual-purpose lock according to the structure of the present invention, in which a hollow slider 3 having a latch bolt 2 at its tip is biased forward by a spring 4 and inserted loosely. A tubular case 5 is embedded in a mounting hole 7 drilled in a door 6.

In addition, circular seats 8 are attached to both sides of the door 6 as appropriate, and
A pin 10 installed vertically along the surface of the door 6 at a predetermined position inside the dial washer 9 has an opening/closing mechanism extending outside the meat through a slit 11 bored nearby. A lever 12.12 is pivotally supported in a horizontal plane so as to be openable and closable, and its respective proximal ends 13.13 are engaged with the rear end 14 of the slider 3, and are held down by a spring 15 attached to the pin. It is designed to encourage people.

Reference numeral 16 denotes a locking mechanism, and an arrow-shaped lock cam 17 is pivotally supported at a predetermined rear position inside the tubular case 5 so as to be switchable in the vertical direction of the door. A pressure is applied to the inner surface of the tubular case 5 on the side toward the circular seat 8, and a recess 19 provided on the upper surface thereof, and the inner surface on the circular seat 8 side of the tubular case 5 as shown in FIGS. 5 and 6. The protrusions 20 , 21 , 22 provided in three fan-shaped positions on the inner surface selectively serve as retaining parts, and the lock cam 17 is attached to each protrusion 20 .
, 21, 22, the flip-flop is biased to switch at the position where it engages with the flip-flops.

Furthermore, the hollow portion of the slider 3 has locking portions 23.2 on both sides.
4, 25, and the lock cam 17 has a protrusion 21. Or, at the position where it is engaged with 22, its tip end is connected to the locking part 2.
3.24, and when this comes into contact, the backward stroke of the slider 3 can be restricted and the slider 3 can be locked.

Note that the protrusions 21 and 22 are positioned symmetrically with respect to the protrusion 25 so that either one can be selectively used depending on the manner in which the locking operation section is installed.

Note that when the lock cam 17 is in a position where it engages with the protrusion 20, that is, in a neutral position, the locking parts 23, 24 are not brought into contact with the lock cam 17.

Further, the locking portion 25 is capable of engaging with the internal protrusion 26 of the tubular case 5, thereby regulating the forward stroke of the slider 3.

Reference numeral 27 denotes a push button as a locking operation part, which has a cylindrical finger rest part 28 with a round tip, a boss-shaped large diameter part 29, a piece-shaped stepped part 30, and a tip rod part 31 with a rectangular cross section. The large diameter portion 29 has a meandering groove 3 on its side surface.
2 is engraved therein, and is attached to the circular seat 8 via a washer 33 and a cylindrical case 34 with a flange, and is pressed by a spring 35 housed in the case 34. 27 is biased towards the surface of the circular seat 8 so that only the finger contact portion 28 is exposed to the outside of the circular seat 8.

Further, the tip end rod portion 31 is fitted into a rectangular hole in the shaft portion of the lock cam 17.

The hollow portion of the washer 33 is provided with claws 36, 36 protruding from both sides, which are engaged with the meandering groove 32 of the push button 27 to provide a mechanism for converting the pushing force of the push button into rotational motion. It is said that

Further, the stepped portion 30 is engaged with the engaging protrusion 37 of the lever 12 inside the circular seat 8, so that they are interconnected.

In the above configuration, when the door 6 is unlocked, that is, the pushbutton 2
The stepped portion 30 of the lever 12 and the engagement protrusion 37 of the lever 12 are not engaged, and the push button 27 is urged toward the surface of the circular seat 8 by the elastic force of the spring 35. When the lock cam 17 connected to the door 6 is engaged with the protrusion 20 at the neutral position A shown in FIG. 6, and the sliding stroke of the slider 3 is not restricted, when opening the door 6, , when one of the levers 12 is pulled up in a horizontal plane, its base end 13 rotates around the pin 10, and the slider 3 is moved through the rear end 14 that engages with the base end 13.
slides rearward, and the latch bolt 2 at its tip retreats to release the lock with the lock seat on the opposite column (not shown), allowing the door 6 to be opened. Returns to prone position.

During this time, no movement is transmitted to the other lever 12 and the other lever 12 remains stationary.

Next, when closing the door 6, when the door 6 is pressed and rotated at an appropriate position, the latch bolt 2 and the slider 3 are moved by the action of the slope of the latch bolt 2 at the position where it comes into contact with the opposing wall. The latch bolt 2 is inserted into the opening, and the latch bolt 2 is inserted into the door 6 at a lock seat (also not shown) carved in the opposing column.
is locked.

Furthermore, the levers 42 and 12 are also driven during this operation. The stationary state is maintained without any movement.

Next, in order to lock the door when closing, it is sufficient to press the push button 27, but when this is pressed, the pressing movement is stopped by the conversion mechanism of the meandering groove 32 and the pawl 36 of the washer 33 that engages with the meandering groove 32. The push button 27 rotates as a result of the rotational movement, and the lock cam 17 is also rotated from the A position to the B position and engaged with the protrusion 21. The stepped portion 30 of the push button 21 engages with the engagement protrusion 37 of the lever 12 and is maintained in a stationary state.

Therefore, in the above state, the slider 3 is attached to the locking portion 2.
Since the backward stroke from the contact position of the slider 3 and the lock cam 11 is restricted, even if a backward force is applied to the slider 3 by operating the lever 12 on the hand washer 9 side in the locked state, the slider 3 will not be locked. It is not possible to completely release the condition.

To release the locked state from this locked state, when the lever 12 on the circular seat 8 side is pulled up, the engagement between the engaging protrusion 37 and the stepped part 30 is released, and the push button 21 is released. The lock cam 17 is returned to the A position by the elastic pressure of the spring 35, and the lever 12 is therefore freely opened and closed in a horizontal plane, thereby unlocking the lock.

Next, the embodiments shown in Figures 9a and 9b and below are other embodiments. 9 is also provided with a well-known appropriate cylinder 39, and a rod 40 with a rectangular cross section that connects the two is inserted through the lock cam 17, and the locking operation is performed using the rotary knob 38 and key. , and then lever 1
The operating mechanism according to No. 2 is kept out of interference.

In addition, in the case shown in FIGS. 10a and 10b, a well-known rotary knob 38 is freely installed on the circular seat 8, and a similarly well-known locking display mechanism 41, such as a rotary disc type, is attached to the forest products 9. The lock cam 17 can be operated by a rod 40 having a rectangular cross section that connects the two.

Note that 42 is a well-known appropriate operation unit that can be operated by an emergency screwdriver or the like.

As described above, according to the invention of this application, in the structure of a dual-purpose lock in which an opening/closing mechanism and a locking mechanism are linked to a slider having a latch bolt that also functions as a dead bolt at its tip, a lock cam is pivotally supported on a tubular case. is made switchable within the flip-flop by a spring that presses and urges this, and a retaining part interposed between the lock cam and the tubular case, and is also capable of coming into contact with the retaining part of the slider. Since the locking mechanism has a structure in which the locking operation section is connected to the lock cam, the structure is extremely simple compared to conventional locking mechanisms, and it is possible to use not only the locking mechanism but also this locking mechanism. Since the tubular case housing the door can be made compact, it is easy to attach it to the door, and the lock cam can be locked simply by applying a narrow-angle rocking motion. Since the lock cam can maintain its posture in a flip-flop manner by itself in the rocking and energized position, it is only necessary to connect it directly to the locking operation section using a rod, and in particular, the locking operation section should be provided with a flip-flop-like posture maintenance mechanism, etc. The entire lock mechanism is simple and design is flexible, and the manufacturing process is easy. Not only can it significantly reduce costs, but it also has the advantage of having almost no risk of failure. .

Further, as the locking operation section, a rotary knob is attached to one side of the mounting seat, and a key cylinder is attached to the other side, and these and the locking cam are integrally connected with a rod to form a locking mechanism, which makes the operation easy and, Although it is robust and highly safe, it can be made into an extremely compact and low-cost entrance door compared to conventional ones.

Furthermore, a rotary knob is attached to one side of the mounting base as the locking operation part, and a locking display mechanism is attached to the other side, and these and the locking cam are integrally connected by a rod to form a locking mechanism, so that it can be used for a single-sided operation door. In this case, as described above, the lock cam can maintain its posture by itself in a flip-flop manner, so the lock display mechanism can be a simple one such as a colored disc or semi-disc. This also has the effect of reducing the operational load from other surfaces and making it easy to use for interior doors, etc.

Further, a push button loosely inserted into the mounting seat via a return spring and a mechanism for converting rotational motion is connected to the lock cam to actuate the locking mechanism, and a lever pivotally supported on the mounting seat is connected to the lock cam. The slider can be engaged to form an operating mechanism, and the push button and lever can also be engaged, so the door can be locked simply by pressing the push button. Furthermore, the present invention has the remarkable effect that a one-touch lock with extremely good operability, which can be easily opened by simply operating the lever, can be manufactured with a simple structure.
