<First Embodiment>
As shown in FIG. 1, the locking device 2 of the present embodiment is attached to a combination stile of two shoji screens 11 and 12 constituting the fitting 1 such as a window and a door, and the fitting can be locked and unlocked. .. As shown in FIG. 2, the locking device 2 includes an operation unit 3 for locking and unlocking the fitting 1 by a rotation operation, a pedestal cover 4 covering the entire pedestal 5, a pedestal 5 fixed to the fitting 1, and a pedestal 5. It has a connecting portion 6 for connecting the operating portion 3 and a crescent receiver 7 for locking and unlocking the fitting 1 together with the operating portion 3. In FIG. 1, the operation unit 3, the pedestal cover 4, and the pedestal 5 of the locking device 2 are fixed to the side surface of the combination stile of one shoji 11, and the crescent receiver 7 is fixed to the front of the combination stile of the other shoji 12. .. In FIGS. 1 and 2, the pedestal 5 is covered with the operation unit 3 and the pedestal cover 4 and is not exposed.

The operation unit 3 has an operation handle 31, a crescent 33 that engages with the crescent receiver 7 to lock the fitting 1, and a sublock 34 and a lock mechanism 35 that prohibit the rotation of the operation handle 31 and the crescent 33. The operation unit 3 can be rotated 180 ° clockwise around the rotation shaft unit 61 (described later) from the state shown in FIG. Since the operation unit 3 is repeatedly loaded with the load due to the locking / unlocking operation and the opening / closing operation of the fitting 1, it is preferable that the operation unit 3 has high strength. The operation unit 3 is preferably made of, for example, nylon containing glass fiber or a metal part.

Crescent 33 has an arcuate shape as shown in FIG. The crescent receiver 7 is attached to the front side of the shoji 12 and has an engaging portion that engages with the crescent 33. In the present embodiment, the fitting 1 is a sliding shoji screen. By setting the operation unit 3 at the rotation angle shown in FIG. 1 with the shoji closed, the crescent 33 engages with the crescent receiver 7 and restrains the fitting 1 so that it cannot move in the left-right direction, so that the shoji does not open. Lock it.

The pedestal cover 4 of the locking device 2 of the present embodiment is composed of two cover members 40. The material constituting the cover member 40 is not particularly limited. The cover member 40 can be made of, for example, a resin or the like, and is preferably water resistant because it is expected to come into contact with water droplets generated by dew condensation. As shown in FIGS. 3A and 3B, the two cover members 40 have a shape in which the upper surface portion 41, the side surface portion 42, and the end surface portion 43 form four surfaces of a substantially rectangular parallelepiped, and the pedestal 5 is contained therein. Can accommodate and cover half. As shown in FIGS. 1 and 2, the two cover members 40 are configured to be butted against each other so as to cover the substantially rectangular pedestal 5 in half.

That is, the two cover members 40 are configured so as to cover the entire pedestal 5 fixed to the shoji 11 with five surfaces of the substantially rectangular parallelepiped in total. As a result, as shown in FIG. 2, the pedestal 5 is not visible to the user in the front view and the side view of the fitting 1, and only the cover member 40 is exposed. Therefore, even if the cover member 40 is discolored due to aged deterioration, the color difference from the pedestal 5 does not appear, and the design of the locking device 2 is improved.

In the present embodiment, the cover member 40 covers the entire pedestal 5 as long as the pedestal 5 is not visible in the front view and the side view of the fitting 1. The front view of the fitting 1 means that the fitting 1 is viewed from the direction in which the sublock 34 is held in FIG. The side view of the fitting 1 means that the fitting 1 is viewed from the direction in which the operation handle 31 is held in FIG.

In the present embodiment, the two cover members 40 are butted against each other on the center side of the pedestal and have a seam portion. The seam is shielded by the operation unit 3 and is not exposed in the front view and the side view of the fitting 1. That is, in the front view of the fitting 1, the seam between the two cover members 40 is shielded by the subblock 34 and is not visible, and in the side view of the fitting 1, the seam between the two cover members 40 is the operation handle 31 or the crescent. It is shielded by 33 etc. and cannot be visually recognized. This improves the design of the locking device 2.

The two cover members 40 do not necessarily have to be directly butted against each other. Even if there is a gap between the two cover members 40 and the pedestal 5 is partially exposed, the pedestal 5 is the sublock 34 in the front view of the locking device 2 and the operation handle 31 or the crescent 33 in the side view. This is because if it is hidden, a part of the pedestal 5 cannot be visually recognized.

Further, a part of the pedestal 5 may be exposed on the surface of the locking device 2 on the shoji 12 side. This is because a part of the pedestal 5 exposed on the back surface is not visible in the front view and the side view of the fitting 1.

The two cover members 40 may be made of the same material and color tone as the operation unit 3. This is because the appearance is unified and the design is improved. Further, the crescent 33 and the sublock 34 may also be configured in the same color tone.

The cover member 40 further has a protrusion-shaped open engaging portion 44 formed on the surface of the side surface portion 42 on the side covering the pedestal 5, and a protrusion-shaped closure formed on the surface of the end surface portion 43 on the side covering the pedestal 5. It has an engaging portion 45. As shown in FIGS. 4 and 5, the open engagement portion 44 is assembled so as to engage with the groove portion 52 of the pedestal 5.

The cover member 40 can be opened and closed by sliding along the groove portion 52. That is, when the cover member 40 is opened and closed by sliding, the open engaging portion 44 engages with the groove engaging portion 53 of the pedestal 5, so that the cover member 40 is held in the open state. The open state is a state in which the pedestal 5 as shown in FIG. 5 is exposed, and the closed state is a state in which the entire pedestal 5 is covered as shown in FIG. The closed engaging portion 45 of the cover member 40 engages with the engaged portion 55 of the pedestal 5 in the closed state and holds the closed state.

The cover member 40 has a recess 46 into which the rotation shaft portion 61 of the connecting portion 6 is inserted when the cover member 40 is attached to the pedestal 5 and closed. As a result, the pedestal 5 can be covered up to the side surface of the portion where the rotating shaft portion 61 is located, so that the design of the locking device 2 is improved.

The pedestal 5 is composed of a metal back plate member that is screwed and fixed to the fitting 1. The pedestal 5 is fixed to the fitting 1 by being screwed via the fixing portion 51. The pedestal 5 further has a groove portion 52 for assembling the cover member 40, and the groove portion 52 is formed with a groove engaging portion 53.

The pedestal 5 further has a connecting portion 6 connecting the pedestal 5 and the operating portion 3 between the two fixing portions 51. The connecting portion 6 is arranged on the rotating shaft portion 61, the support portion 62 that is caulked and fixed to the pedestal 5 to support the rotating shaft portion 61, the handle mounting portion 63 to which the operation handle 31 is attached, and the back surface of the pedestal 5. It is configured to have a stopper 64 (not shown) that limits the rotation angle of the operation handle 31.

That is, the substantially rectangular handle mounting portion 63 meshes with the operation handle 31, so that the rotation operation of the operation handle 31 can be transmitted to the rotation shaft portion 61. Similarly, for the stopper 64, for example, the pedestal side end of the rotating shaft portion 61 having a substantially rectangular shape meshes with the stopper 64 having a substantially rectangular hole portion, and the stopper 64 rotates in response to the rotation of the rotating shaft portion 61. do. When a part of the rotated stopper 64 collides with the pedestal 5, further rotation is restricted, and the rotation range of the operation handle 31 is restricted.

The lock mechanism 35 operates by operating the sublock 34, and limits the rotation of the substantially rectangular handle mounting portion 63 shown in FIG. This locks the rotation operation of the operation handle 31 and prevents a small child or the like from rotating the operation handle 31 to lock and unlock the fitting 1.

As shown in FIG. 6, when the cover member 40 is in the closed state covering the pedestal 5, the closed engaging portion 45 of the cover member 40 is fitted with the engaged portion 55 of the pedestal 5. The cover member 40 is held. The open engaging portion 44 is not engaged with the pedestal 5 in the closed state.

From the closed state shown in FIG. 6, by pinching both side surface portions 42 of the cover member 40 and pulling it to the right side of the paper surface, the cover member 40 is slid with respect to the groove portion 52 of the pedestal 5, and the pedestal 5 is exposed. do. The closed engaging portion 45 is configured so that the engaged portion 55 is disengaged by the pulling operation. As a result, the cover member 40 can be freely opened and closed.

As shown in FIG. 7, the open engaging portion 44 of the cover member 40 is engaged with and held by the groove engaging portion 53 of the pedestal 5 in the open state. As a result, since it is not necessary to completely remove the cover even in the open state, the screw can be opened and closed without holding the cover member 40 by hand, and the engagement adjustment work between the crescent 33 and the crescent receiver 7 can be performed. It can be carried out.

As described above, the open engaging portion 44 of the cover member 40 is not engaged with the pedestal 5 in the closed state. The closed engaging portion 45 for holding the cover member 40 in the closed state is formed on the end face portion 43, and is not formed on the side surface portion 42. Therefore, even if the side surface of the cover is pinched, the open engaging portion 44 does not interfere with the engaging portion in the closed state, and the opening / closing operation of the cover member 40 becomes easy.

Further, there is a space for the open engaging portion 44 to slide and move between the side surface portion 42 of the cover member 40 and the groove portion 52 of the pedestal 5. As a result, when the side surface portion 42 of the cover member 40 is strongly pinched, the closed engaging portion 45 bends inward, so that the engagement with the engaged portion 55 is easily disengaged, and the opening / closing operation of the cover member 40 is easy. Become.

The locking device 2 of the present embodiment has been described above. According to the locking device 2, the following effects are achieved.

The locking device 2 has a pedestal 5 fixed to the fitting 1 in the fixing portion 51, an operating portion 3 rotatably attached to the pedestal 5 and capable of locking and unlocking the fitting 1 by a rotation operation, and at least one end of the pedestal 5. It is attached to the side so as to be slidable with respect to the pedestal 5, and by the slide movement, it is possible to switch between a closed state that covers at least the fixed portion 51 of the pedestal 5 and an open state in which the pedestal 5 is exposed. In the locking device 2 having the cover member 40, in the closed state, the cover member 40 holds the closed state by engaging with the engaged portion 55 provided on the end face portion of the pedestal 5. In the open state, the cover member 40 maintains the open state by engaging with the groove engaging portion 53 provided on the side surface portion of the pedestal 5. As a result, the closed engaging portion 45 for holding the cover member 40 in the closed state is formed on the end face portion 43, but not on the side surface portion 42. Therefore, even if the side surface of the cover is pinched, the open engaging portion 44 does not interfere with the engaging portion in the closed state, and the opening / closing operation of the cover member 40 becomes easy.

The side surface portion of the pedestal and the inner surface of the cover member each have an engaging portion in which the cover member engages with each other in the open state. As a result, since it is not necessary to completely remove the cover even in the open state, the screw can be opened and closed without holding the cover member 40 by hand, and the engagement adjustment work between the crescent 33 and the crescent receiver 7 can be performed. It can be carried out.

There is a space between the side surface portion of the pedestal and the inner surface of the cover member. This eliminates the need to completely remove the cover even in the open state. Since the closed engaging portion 45 bends inward when the side surface portion 42 of the cover member 40 is strongly pinched, the engagement with the engaged portion 55 is easily disengaged, and the opening / closing operation of the cover member 40 is facilitated.

The fitting 1 has a locking device 2. Thereby, it is possible to provide the fitting 1 which can easily open and close the cover member 40 and easily adjust the engagement between the crescent 33 and the crescent receiver 7.

The locking device of the present embodiment is not limited to the above-mentioned embodiment. For example, it may be applied to a Gremon lock or a cam latch handle instead of the Crescent lock as in the above embodiment. Further, the locking device of the present disclosure can be applied to various fittings such as a self-propelled door and a terrace door.
