Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a partition lock, and its purpose is to use a partition lock for internal doors in houses, so-called so-called locks that do not require locking in reception areas, living rooms, etc. Used in toilets, baths, living rooms, etc., where the locking mechanism is installed without changing the external shape of the blank lock, and most of the parts of the entire lock are the same as the blank lock, making site construction easier. Providing partition locks. (Prior Art and its Problems) Generally, in a lock having a locking mechanism, it is necessary to use an oval or rectangular long seat for the rose that makes up the appearance of the lock. The reason for this is that the lock mechanism is complicated, as in the lock disclosed in Japanese Utility Model Application Publication No. 58-47668, and the distance between the lever core and the lock mechanism must be longer than that of a lock without a lock mechanism. The rose on the lock was to cover this from the outside of the door. Therefore, their appearance tended to be heavy and heavy. On the other hand, Japanese Utility Model Application Publication No. 57-180058 discloses a mechanism in which the locking mechanism is simplified and the rose has a conical shape with a simple appearance and functional beauty. However, this disclosed lock also has a locking disc with a notch in the handle shaft in the indoor handle seat, and the stopper of the push button shaft attached to this locking disc moves when the latch is extended. It was necessary to provide a notch that matched the direction. Therefore, although it is possible to make the appearance of the lock into a conical shape, in order to make the lock, the handle shaft must be of a specific type, and a cutout disk and push button must be installed in advance inside the handle seat. In order to use such a specific rose, lock locks and empty locks have more common parts, which is not enough to meet the demand for increased industrial productivity. Furthermore, this existing lock requires strict dimensional accuracy during installation and high dimensional accuracy of the parts themselves.Depending on these dimensional accuracy, the lock may not operate correctly after installation, making it difficult to install on-site. was not suitable. In addition, as a lock device with a relatively simple structure, which is a lock equipped with a locking mechanism in which a circular rose is adopted, Utility Model Publication No. 48-91090 and Utility Model Publication No. 54-
There is one described in Publication No. 22558. The locking devices described in these publications have a relatively simple structure, but the operating piece for operating the locking mechanism is provided at right angles to the core that passes through the locking device in the indoor-outdoor direction. Therefore, the stroke required to operate the operating piece must be longer than the diameter of the core material, and the operating piece may protrude from the rosette or the diameter of the rosette itself must be increased accordingly. As a result, the entire locking device became larger. In addition, even if an emergency unlocking mechanism from the outside is attached to the locking device, it is necessary to separately attach an unlocking member perpendicular to the operating piece and parallel to the core material, which reduces the ease of on-site construction. There was also a problem. (Means for Solving the Problems) This invention comprises a lock body, an indoor rose and an outdoor rose that make up the lock body, and which are inserted into a through hole of a latch hub installed in the lock body. This is a partition lock in which the latch hub is rotatable by a core material, and a stopper device is interposed between the lock body and the indoor rose. The rising piece has an angular through hole through which the core material is inserted, is perpendicular to the core material, and is slidable in the axial direction of the core material, and the sliding piece The raised piece extends parallel to the core material from the base end thereof, and its tip faces the unlocking hole drilled in the outdoor rose, and the button is attached to the base end of the raised piece. The tip thereof passes through the rose on the indoor side and extends to the outside of the rose, and the core material is engaged with a locking portion having a square cross section that engages with the square through hole of the upright piece, and the inside of the square through hole. All of the above problems are solved by a partition lock having a non-locking part that does not match. (Example) Hereinafter, a partition lock according to an embodiment of this invention will be explained based on the drawings. Fig. 1 is a partial cross-sectional explanatory view of a conventionally known lock body to be incorporated into a partition lock according to this invention. Te, 1
is a latch, 2 is a latch bolt, 3 is a latch spring, 4 is a spring pressure, 5 is a hub spring, 6 is a latch hub, and 7 is a through hole in the latch hub 6, each of which has a conventionally known operation. . 8 is the casing of such a lock body. FIG. 2 is a front explanatory view of the partition lock 9 according to this invention attached to the door 10, and FIG.
It is a side explanatory view of the figure. In FIGS. 2 and 3, reference numeral 11 denotes a lever, and the rotational power of this lever 11 causes the latch 1 to move in and out. The rotational force of the lever 11, that is, the retraction force of the latch 1, is biased downward in the circumferential direction as shown by the imaginary lines in FIGS. The return force 11 is applied by the elastic restoring force of the hub spring 5 via the spring pressure 4 applied to the latch spring 3 and the latch hub 6, respectively. 4 and 5A, B, and C are cross-sectional and external explanatory views of a locking device for a partition lock according to this invention. In the drawings, 15 is a stopper device interposed between the casing 8 of the lock body and the rose 13a on the indoor side. 14 is a core material, and this core material 14 is the indoor rose 1
3a, the outdoor rose 13b passes through the casing 8 of the lock body and is inserted into the through hole 7 of the latch hub 6 installed in the casing 8, and has levers 11 at both ends of the core material 14, that is, on the indoor side and the outdoor side. is installed. The stopper device 15 consists of a rising piece 17, a sliding piece 16, and a button 12. The upright piece 17 has an angular through hole 22 through which the core material 14 is inserted. The upright piece 17 is attached to the core member 14 through the square through hole 22, is perpendicular to the core member 14, and is slidable in the axial direction of the core member 14. The slide piece 16 extends parallel to the core member 14 from the base end 17a of the rising piece 17, and its tip is attached to the outdoor rose 13b.
It faces an unlocking hole 19 drilled parallel to the . This unlocking hole 19 is used to insert a pin or the like into the unlocking hole 19 in case of an emergency, for example, when a person falls down in the toilet and the lock is locked from the indoor side.
This is for releasing the locked state by sliding the stopper device 15 toward the indoor side by the pressing force of the pin. This slide piece 16 and the rising piece 17 are L
It may be formed by bending into a letter shape, or it may be welded by spot welding or the like. The button 12 is attached to the proximal end 17a of the rising piece 17, and its tip passes through the indoor rose 13a and extends outward from the rose 13a. By operating this button 12 back and forth, the stopper device 15 is operated.
In some cases, a notch 18 is provided in the sliding surface of the button 12 with the rose 13, and a spherical locking member 20 is inserted into the sliding hole drilled in the rose 13 in a vertical direction. A mechanism may be adopted in which an elastic screw body is embedded to provide elastic force to the stopper device 15, and the spherical locking member 20 is fitted and locked in the notch 18 in stages to slide the stopper device 15 in stages. . Note that the shape of the slide piece 16 and the rising piece 17 of the stopper device 15 as described above is not limited to the L-shape shown in FIGS. 4 and 5 A to D.
Other modified shapes, such as the inverted T-shape and horizontal F-shape shown in FIGS. 6B and 6C, can also be adopted as long as they do not depart from the spirit of this invention. Of course, depending on the change in the shape of the stopper device 15 , the locking portion 23 of the core material 14,
It is necessary to change the location where the unlocked location 21 is formed. The core material 14 has an angular through hole with a locking portion 23 where the angular through hole 22 engages in a sliding portion d of the core material 14 where the angular through hole 22 of the upright piece 17 of the stopper material 15 comes into contact. It has a non-locking portion 21 which the hole 22 does not engage with. The locking portion 23 has a square cross section to engage with the square through hole 22, and the non-locking portion 21 has a circular cross section in this embodiment. Therefore, even if the locking part 23 is a square core and the non-locking part 21 is a round core as shown in FIGS. 5C and D, conversely, as shown in FIG. 6A
As shown, the locked part 23 is a round core and the non-locked part 21
may be a square core. Further, the square through-hole 22 may be square as shown in FIGS. 5A, B, and C, or may be a polygon other than this. In this case, the core material 1
Naturally, the locking portion 21 of No. 4 has a polygonal shape corresponding to the polygonal shape of the angular through hole 22. After attaching the partition lock 9 according to this invention having the above configuration to the door 10 etc., when the user operates the button 12 with his finger and pulls it towards the indoor side, the stopper device 15 is parallel to the core material 14. Figures 4 and 5
In the embodiment shown in Figures C and D, the square through hole 22 abuts against the unlocked portion 21 of the core 14, and the lock body becomes unlocked. When the button 12 is pushed in the direction of the door 10, the stopper device 15 moves forward in the direction of the casing 8 of the lock body parallel to the core material 14, so that the square through hole 22 engages with the locking part 23 of the core material 14, The latch 14 and therefore the latch 1 and the lever 11 are locked (see FIGS. 5C and 5D). This locking operation can be achieved by forming the locking point 23 in the direction of the indoor rose 13a and the unlocking point 21 in the direction of the casing 8 of the lock body, and the locking and unlocking operations are performed by operating the button 12 in the opposite direction. (Effects of the invention) As detailed above, this invention comprises a lock body, an indoor rose and an outdoor rose that make up the lock body, and which are inserted into the through hole of the latch hub installed in the lock body. This is a partition lock in which the latch hub is rotatable by a core material, and a stopper device is interposed between the lock body and the indoor rose. The rising piece has an angular through hole through which the core material is inserted, is perpendicular to the core material, and is slidable in the axial direction of the core material, and the sliding piece is made of a square through hole through which the core material is inserted. extending from the proximal end of the upright piece in parallel to the core material, with its tip facing an unlocking hole drilled in the outdoor rose;
The button is attached to the proximal end of the upright piece, and its tip passes through the indoor rose and extends outward from the rose, and the core engages with the square through hole of the upright piece. Since this partitioning lock has a locking portion having a square cross section and a non-locking portion that does not engage within the square through hole, it has the following effects. The partition lock can be reliably locked because it has a mechanism that locks the core member that directly transmits the rotational force of the door lever to the latch, that is, the center member that carries the rotational moment. As mentioned above, the lock mechanism has a simple structure consisting of a stopper device in which the raising piece, slide piece, and button are constructed as one member, and the shape of the core material, so all other parts can be used in common with the empty lock. By simply adding this locking device to an empty lock, it can be made into a lock for partitioning, which provides excellent factory productivity and easy on-site construction. In addition, since the stopper device is slidable in the same direction as the axial direction of the core material, this raised piece does not extend outside the diameter of the rosette, and the stopper device prevents the partitioning lock from being extended out of the diameter of the rosette. This eliminates the inconvenience of increasing the size. Moreover, since the stopper device is slidable in the same direction as the axial direction of the core material as described above, the tip of the sliding piece of the stopper device faces the unlocking hole drilled in the outdoor rose. By pushing a pin or the like through the unlocking hole, the door can be unlocked from outside. Since such an unlocking mechanism is also used by the stopper device having the above structure, it is possible to solve the complexity of the locking device and the difficulty of on-site construction by providing a separate unlocking mechanism as in the past. .
