Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an indoor lock lock with a display mechanism, and more particularly to a latch actuation angular shaft between indoor and outdoor lever handles, and The present invention relates to a two-axis indoor lock lock in which a lock shaft between the indoor-side knob portion and the outdoor-side display portion is a separate axis. The most important feature of the two-axle indoor lock lock is that it can easily and quickly set and change the left hand, right hand, and other hanging hand.

[Conventional technology]

Conventionally, there has been a uniaxial type lock lock for indoor use. This is the shaft part of the indoor / outdoor lever handle,
A latch is connected by a square shaft for latch operation, and an inner shaft connected by a connecting rod to a knob on the indoor side is provided in the shaft portion of the outdoor lever handle, and projects in the circumferential direction when the center shaft rotates. The lock pin can be locked by the lock plate in the outdoor mounting seat frame (see, for example, Shokai 63-2138).
(See Publication No. 1).

However, since the return spring of the lever handle is provided in the mounting seat frame in this one-shaft type indoor lock lock, the thickness of the mounting seat frame becomes large, and it is difficult to make a good-looking indoor lock lock.

Therefore, recently, although not shown, an indoor lock lock has been introduced by using a "spring latch" in which a spring for returning the rotation of the lever handle is incorporated in the latch.

This is a two-axis construction in which a latch is mounted between the indoor side and outdoor side lever handles, and an angular axis for latching the shaft is mounted, and a locking axis between the indoor side knob portion and the outdoor side display portion is a separate axis. . The lock mechanism is a lock actuating member that can be raised and lowered by the indoor side knob, and locks a locked portion formed on the lever handle shaft.

[Problems to be solved by the device]

Generally, in the lever handle lock, it is necessary to switch the lever handle between right hand and left hand depending on whether the door opens right or left. Therefore, the lever handles on the indoor side and the outdoor side are once pulled out from the mounting seat frames on each side, and are replaced with left and right sides reversed. Therefore, this switching work is troublesome and cannot be performed well by an amateur.

Further, due to the necessity of pulling out the lever handle, a clearance is provided between the shaft portion of the lever handle and the mounting seat frame. This clearance is amplified at the position of the lever handle away from the shaft center, which causes the lever handle to rattle.

Further, the lock mechanism of the two-axis type indoor lock lock locks by locking the locked portion formed on the shaft portion of the lever handle. Since this is locked at a position close to the axis, if a child hangs on the lever handle at the time of locking or an adult applies excessive force, the force will increase at a position close to the axis. There was a problem that the lock mechanism was damaged.

On the other hand, some of the so-called uniaxial lever handle locks have been designed with consideration given to changing the hanging hand. For example, the actual exploitation 63
This is the lever handle lock described in Japanese Patent Publication No. 187679, which is located at the line symmetrical position of the outer peripheral edge of the return spring holding body (the locking plate in the present invention) that rotates via the angular axis when the lever handle rotates. , Handle positioning locking claw (projecting piece for locking)
A handle positioning recessed portion (same locking recessed portion) that is horizontally longer in the circumferential direction is provided.

To change the lifting hand with this lever handle lock, change the fixing screw that fixes the handle positioning locking claw to the mounting base,
Loosen and remove with a tool such as a screwdriver, once remove the handle positioning locking claw, turn the lever handle in the opposite direction, position the handle positioning locking claw again on the mounting base, and screw in the fixing screw. It is tightened and fixed.

However, the operation of loosening and removing the fixing screw, once removing the handle positioning locking claw, and then tightening and fixing the handle positioning locking claw by screwing the fixing screw can easily change the lifting hand. It is hard to say.

An object of the present invention is to solve the problems of the conventional two-axis type indoor lock lock. The purpose of the present invention is to have a relatively simple structure, and can handle right-handed and left-handed hands without pulling out and replacing the lever handle, eliminating rattling of the lever handle, and external force applied to the lever handle. The object of the present invention is to provide a biaxial type indoor lock lock in which the lock mechanism has sufficient strength.

Configuration of the Invention [Means for Solving the Problems] The indoor lock according to the present invention comprises a latch actuating angular shaft (5) for connecting between indoor side and outdoor side lever handles (3) and (4), and a room. A two-shaft type indoor lock lock in which a lock shaft (8) connecting between the inner knob part (6) and the outdoor display part (7) is configured as a separate shaft, wherein at least the outdoor lever handle ( 4) is retained by the locking rig (10) fitted to the shaft portion (9) to the outdoor-side mounting seat frame (2) and is axially supported, and either the indoor side or the outdoor side is supported. A shaft (9) of the lever handle (4) is provided with a locking disc (14) which is rotatable integrally with the shaft (9), and is a separate shaft for locking (8). A lock actuating plate (12) that is actuated by the rotation of the lock shaft (8) is provided on the The locking projection (13) formed on the lock actuating plate (12) can be engaged with the lock operating plate (12), and the locking recess (15) (16) is laterally elongated from the locking projection (13). ) Is formed on the outer periphery of the lock disc (14) at the intermediate position between the lock recesses (15) and (16) at the same time. ), And a stopper member (17) having a locking projection (18) engageable with the locking recess (15) (16) on the opposite side of the locking projection (13).
By urging the stopper member (17) against the spring (19) by urging the spring (19) toward the locking disc (14), the recessed part (25) for shipping can be obtained. Or the locking recess (1
The locking projection (18) that is engaged with 6) is released, and the rotation of the locking disc (14) is temporarily completely freed, making it easier to set or change the lifting hand. It is a thing.

In the above-mentioned structure, the two shafts of the latch actuating angular shaft (5) and the locking shaft (8) are normally supported on the vertically long indoor / outdoor mounting seat frames (1) and (2) in two upper and lower stages. However, it is not necessarily limited to the vertical position.

Of the lever handles (3) and (4), at least the outdoor lever handle (4) is secured to the outdoor mounting seat frame (2), but not limited to this, the indoor lever handle (3).
Alternatively, it may be retained in the indoor mounting seat frame (1).

It is desirable that the outer diameter of the locking disc (14) be large within a designable range.

In the figure, (11) is a cam member, (20) is a door, and (2)
1) is a latch, and (15a) (15b) (16a) (16b) is an inner surface of each locking recess (15) (16).

[Action]

a) When the indoor lock lock according to the present invention is attached to a door The lever handles (3) and (4) are attached to the mounting seat frame (3) so that the indoor lock lock configured as described above does not become bulky at the time of shipment or stock from the factory. 1) It can be set in a state along the longitudinal direction of (2).

That is, the stopper member (17) with the locking projection (18) is pushed against the spring (19), and the locking projection (18) is formed on the locking disc (14) without any recess. The lock disc (14) can be freely rotated by detaching it from the parts (15) (16) (25), and the lever handle (3) ( 4) Turn so that the mounting seat frames (1) and (2) extend along the longitudinal direction.

With this, the factory shipping recess (25) formed on the locking disc (14) comes to a position corresponding to the locking projection (18) of the stopper member (17), so that the spring (19) The locking projection (18) of the pushed stopper member (17) is provided with the shipping recess (2).
The lever handle (3) (4) is locked at that position and becomes immobile. Therefore, the lock lock for the present room can be transported and stocked without making the lever handles (3) and (4) bulky or moving carelessly.

Then, in order to attach the indoor lock lock in the above state to the door (20) at a construction site or the like, the stopper member (17) is again used.
Is pushed against the spring (19) to disengage the locking projection (18) from the shipping recess (25), thereby freeing the locking disc (14) from rotating. In this state, depending on whether the door (20) is left-handed or right-handed, turn the lever handles (3) (4) left or right.

Now, any one of the locking recesses (15) and (16) formed in the locking disc (14) through the angular axes (3) and (4) (in FIGS. 1 to 3). , (16) are the locking recesses (15)), and the locking projections (18) of the stopper member (17).
Since it comes to a position corresponding to, the locking projection (18) of the stopper member (17) pushed by the spring (19) engages with the locking recess (16), and the left or right desired It has been set for hanging.

Further, in the indoor lock lock of the present invention, as described above, at least the outdoor lever handle (4) has the locking ring (10) fitted to the shaft portion (9) of the outdoor outer mounting seat frame ( 2)
The shaft is supported by retaining it.

Therefore, when mounting the mounting seat frames (1), (2) and the lever handles (3) (4) on the inside and outside of the door (20) on each side, at least for the outside, it is easy and quick. Can be installed.

Further, since the outdoor side lever handle (4) is prevented from being pulled out from the outdoor side mounting seat frame (2) as described above, the outdoor side mounting seat frame (2) and the shaft portion (9) of the lever handle (4). In the meantime, no clearance for pulling out and replacing is required.

Therefore, after the lock is attached to the door (20), no large rattling occurs even at the position of the lever handle (4) away from the shaft center.

b) When the lock lock of the present invention is set in the locked state (first
(See FIGS. 4A and 4B) The knob portion (6) on the indoor side is turned, and the display portion (7) on the outdoor side is locked by the lock shaft (8).

With this, the cam member (11) on the lock shaft (8) moves the lock operating plate (12) to the lock disc (14) side,
The locking projection (13) of the lock operating plate (12) has a pair of locking recesses (15) on the outer peripheral edge of the locking disc (14).
Among the parts (16), they are engaged with the locking recesses ((15) in FIG. 1 and (16) in FIG. 4) on the locking projection (13) side.

Therefore, the rotation of the locking disc (14) in the direction in which the lever handles (3) (4) are lowered causes the locking projection (13) to rotate inside the locking recesses (15) (16). [(15
a) and (16a) in FIG. 4 are locked, so that their rotation is blocked and they are in a locked state. Therefore, the lever handles (3) and (4) do not move, the latch (21) projects and remains engaged with the locking metal fitting (not shown) of the door (20), and the door (20) cannot be opened. .

In the above case, the rotation of the locking disc (14) in the direction of raising the lever handles (3) and (4) causes the stopper member (1) to rotate.
The locking convex piece (18) of 7) has a locking concave portion [1st
(16) in the figure, (15) in FIG.
Since it is in contact with (16a) in the figure and (15a) in FIG. 4,
Its rotation is also blocked.

Further, the locking projection (13) is locked by
It is not the shaft portion (9) of the lever handle (4) close to the shaft center, but the lock recesses (15) (16) at the outer peripheral edge of the lock disc (14) distant from the shaft center.

Therefore, the lever handle (3) (4) when locked
Even if a child hangs down, the external force is applied to the locking recesses (15) (16) and locking projections (1
3) increased and does not work, there is no damage to them.

c) When locking the lock of the present invention in an unlocked state (see FIGS. 2 and 5), turn the knob (6) on the indoor side and display the outside of the room via the locking shaft (8). The section (7) is unlocked.

As a result, the cam member (11) moves the lock actuating plate (12) away from the lock disc (14), so that the locking projection (13) engaged as described above has the locking recess. Division (15)
Leave from (16).

As a result, the locking disc (14) is unlocked by the locking projection (13) and brought into the unlocked state, and the lever handles (3) and (4) can be rotated in the lowering direction. When the lever handles (3) and (4) are lowered, the latch (21) retracts via the latch actuating angular shaft (5), so that the door (20) can be opened.

In the above case, the lateral width of the locking recesses (16) (15) is longer than the lateral width of the locking projection (18) of the stopper member (17) engaged therewith. Therefore, the lever handle (3) (4)
When it is lowered, the lock disc (14) can be rotated by a certain angle by the length of the horizontal width, and if it is further rotated, the lock disc (14) (15) inner surface can be rotated. [(16b) in Fig. 2,
(15b) in FIG. 5 abuts on the locking projection (18) and does not rotate any further.

d) When the lock of the present invention is switched from left-hand to right-hand, or vice versa, in this case, the inside / outside lever handle (3)
It is necessary to change the direction of (4) to the opposite direction.

In the lock lock for indoor use of the present invention, first the unlocked state, the stopper member (17) is pushed against the spring (19),
The lifting hand can be changed simply by turning the lever handles (3) and (4) to the opposite positions.

That is, when the stopper member (17) is once pushed against the spring (19), the locking projection (18) engages with the locking recess (first part) of the locking disk (14). In FIGS. 1 to 3, the lock recess shown in (16) is removed (3rd part).
See figure). Since the locking disc (14) is free to rotate, the lever handle (3) is integrated via the square shaft (5).
(4) is rotated to the opposite position.

Now, among the locking recesses (15) (16) formed in the locking disc (14), a different locking recess (the lock shown by (15) in FIG. 4). Recess (15) for
Comes to a position corresponding to the locking projection (18) of the stopper member (17), so that the locking projection (18) of the stopper member (17) pressed by the spring (19) is pushed into the locking recess. It engages with the notch (15), and it has been changed to the right or left hanging hand which is the opposite of that.

In this state, the locking projection (13) of the locking actuating plate (12) is indicated by (15) in FIG. 1 to FIG. In contrast to the lock recessed portion), another lock recessed portion (FIG. 4 and FIG.
It becomes possible to engage with the lock recessed part shown in 6).

As described above, in the indoor lock lock according to the present invention, it is not necessary to temporarily pull out the lever handles (3) and (4) from the mounting seat frames (1) and (2) when changing the suspending hand, unlike the conventional one. . In addition, it does not take the trouble of loosening the fixing screw and removing it, once removing the handle positioning locking claw, and tightening the handle positioning locking claw again with the fixing screw, making it easy and quick to lift. It can be changed.

〔Example〕

In the illustrated example, the indoor / outdoor mounting seat frames (1) and (2) are vertically long, and the latch actuation angular shaft (5) and the locking shaft (8) are vertically supported in two upper and lower stages. It has a general shape.

Although the shaft portion (9) of the outdoor lever handle (4) is retained by the outdoor mounting seat frame (2) so as to be axially supported, the shaft portion (9) of the indoor lever handle (3) is Inner mounting seat frame (1)
I have not stopped it.

On the outer peripheral edge of the locking disc (14), a pair of locking recesses (15) (1
6) has been formed. Of the locking recesses (15) (16), the locking projection (13) of the lock actuating plate (12) can be engaged with the one located in the upper position, and the one located in the lower position. The stopper member (1
The locking projection (18) of 7) is engaged.

The locking recesses (15) (16) are formed in line symmetry rather than point symmetry, and are located on one side on the outer peripheral edge of the locking disc (14) (the seventh position). (See Fig. 8). The length of the locking recesses (15) (16) is, for example, about twice the width of the locking projection (13) or the locking projection (18), or about 60 degrees in terms of angle. To do. In this example, about 30 degrees becomes the rotatable angle of the locking disc (14), in other words, the movable range of the lever handles (3) and (4).

Reference numeral (22) denotes a lock disk support, which is provided inside the outdoor-side mounting seat frame (2), and the lock disk (14) is rotatable inside. At the upper part of the bearing part (22),
The locking protrusion (13) has a passage guide groove (23), and the locking protrusion (18) has a passage lower guide groove (24).
Has been formed.

(25) shows the recess for shipping, lever handle (3)
When the (4) is placed along the vertically long mounting seat frames (1) and (2), the locking projection (18) can be engaged, and the locking disc (14)
It is formed at an upper and lower intermediate position on the outer peripheral edge.

Effect of the Invention The indoor lock according to the present invention can handle right-handed / left-handed doors that can be opened right or left without pulling out the lever handle and replacing it. Also, the rattling of the lever handle can be eliminated, and the lock mechanism can have sufficient strength against external force applied to the lever handle.

That is, in the conventional indoor lock lock of this type, in order to handle right-handed and left-handed hands, the lever handle had to be pulled out and replaced in the opposite direction. Therefore, there is a clearance between the lever handle shaft and the mounting seat frame.
This was amplified at the position of the lever handle away from the shaft center, which caused rattling. Further, since the lock mechanism locks the shaft portion of the lever handle, when a force is applied to the lever handle at the time of locking, the force is increased near the shaft center and acts, and the lock mechanism is damaged.

On the other hand, unlike the conventional lock lock for indoor use according to the present invention, it is possible to rotate the lever handle for changing the hanging hand only by pushing down the stopper member. Therefore, when the lever handle is turned to the opposite position, the lever is locked by the locking projection of the stopper member that is pushed by the spring, and the changed hanging hand is maintained. As in the past, pull out the lever handle and replace it in the opposite direction, loosen the fixing bolt and remove the locking claw, turn the lever handle in the opposite direction and tighten the locking claw again with the fixing bolt, etc. Anyone can easily and quickly change the locking mechanism of the lock according to the door, without the need for the work.

Similarly, in the indoor lock according to the present invention, the stopper member is temporarily pushed against the spring and the lever handle is rotated so that the lever handle does not become bulky at the time of shipment or inventory, so that the longitudinal direction of the mounting seat frame is reduced. It can be fixed in the state along with. Also, when installing the lock lock for the main room in that state to the door at the construction site, after similarly pushing the stopper member against the spring once, simply turning the lever handle in the direction suitable for the door makes it easier to lift. Can be set.

Further, at least the outdoor side lever handle is retained by the outdoor side mounting seat frame so as to be axially supported, and there is no clearance for pulling out between the mounting seat frame and the shaft portion of the lever handle. Therefore, it is possible to eliminate rattling at the lever handle away from the shaft center. Further, since at least the outdoor lever handle is prevented from being pulled out, the outdoor lever handle does not drop from the outdoor seat frame, and the lock lock is excellent in safety. If the interior lever handle is also pulled out, it will be even more secure.

Moreover, in the present invention, the locking projection of the locking mechanism locks the locking recessed portion on the outer peripheral edge of the locking disc separated from the shaft center. Since the force applied to the lever handle at the time of locking is not increased unlike the case where the lever handle is locked near the shaft center, there is no damage to the locking recess or locking projection and a locking mechanism that is safe in terms of strength can be provided. .
