Description

[Detailed description of the invention]

[0001]

This invention comprises a combination of an inner member having a room-side operation member such as a thumb turn and an outer member having a cylinder, and a deadbolt, a crescent, and a sickle built in either the inner or outer member. The present invention relates to a door lock in which both members are connected to each other by a locking member to be in a locked state.

[0002]

2. Description of the Related Art In a door lock which is divided into inner and outer members,
When the door lock is mounted, it is necessary to align the center of the door lock in the vertical and horizontal directions. In addition, if the construction is distorted during use, it becomes inoperable, so that it is necessary to perform centering again.

By the way, in the related art, no particular contrivance has been made for the centering structure, and at present, the centering is performed in a groping state.

For example, there is provided a structure for checking the alignment of the core through a wire. In this case, it is possible to determine in which direction the core is aligned in the relative relationship between the two. There is. In addition, there is a concern that the search wire may be lost.

[0005]

[Problems to be Solved by the Invention] Therefore, when installing a door lock at the site, it is relatively time-consuming, and maintenance during use is not easy. Therefore, development of some simple centering structure has been awaited. I was just doing.

Therefore, the purpose of this invention is to
It is an object of the present invention to provide a door lock having a centering structure in which the centering state can be confirmed visually and the visual confirmation is extremely clear and easy to determine.

[0007]

In order to achieve the above-mentioned object, in the present invention, a through hole penetrating from the indoor side to the outdoor side is formed, and the alignment state is confirmed by matching the through holes. is there.

That is, the door lock according to the present invention is composed of a combination of an inner member having a built-in operation member on the indoor side and an outer member having a cylinder built therein. Are connected to each other to form a locked state, wherein a through hole is formed which penetrates the inner member and the outer member and opens to the inner and outer surfaces.

[0009] The location of the through hole is not particularly limited. However, if an extra hole is not desired on the outdoor side, the keyway of the cylinder can be used as it is. That is, a through hole may be formed on the horizontal extension of the key groove of the cylinder so as to communicate with the key groove.

[0010]

As described above, in the case where the through holes are formed through the inner member and the outer member and open to the inner and outer surfaces, the alignment can be confirmed by matching the two.
Because it penetrates inside and outside, when the end of one opening is visually observed, the light entering from the other opening appears to shine brightly in the centered state, making it easier and clearer than looking through some visual object. The matching state can be checked.

If this through-hole is formed in a horizontal extension of the keyway of the cylinder, no extra perforation is required in the outer member, which is preferable in appearance and crime prevention.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

As shown in FIG. 1, the door lock of the present invention has an inner member 1 attached to a vertical bar of an aluminum sash.
The inner member 1 is provided with an indoor operation member 3, and the outer member 2 is provided with a cylinder 4.

The indoor operation member 3 is provided so as to be slidable in the vertical direction in the long seat 5, and can operate a known indoor mechanism incorporated in the inner case 7 via the long seat 6. The outer case 8 has a locking member 9 and the
There is a built-in interlocking mechanism that makes it come and go from zero.

As is well known, the locking and unlocking operation is performed from the outdoor side by operating the outdoor side mechanism by a key operation through the cylinder 4 so that the locking member 9 is moved in and out. The operation is performed by operating the outdoor-side mechanism via an indoor-side mechanism that operates in conjunction with the operation of the inner operation member 3, thereby causing the locking member 9 to protrude and retract.

In this example, the linkage between the indoor side mechanism and the outdoor side mechanism is achieved by the engagement state of the interlocking projections 11 and 12 provided on the interlocking member to which permanent magnets attracting each other in the proximity state are attached. It is a matter of course that various known mechanisms can be employed for the lock mechanism itself.

The present invention is characterized in that a through hole 13 is formed through the inner member 1 and the outer member 2 so as to open to the inner and outer surfaces. Open at the outer member 2
, The keyway 14 of the cylinder 4 is used as an open end. That is, a through hole 13 is provided on the horizontal extension of the key groove 14 of the cylinder 4 so as to communicate with the key groove, and the inner member 1 is opened in the indoor operation member 3.

Therefore, as shown in FIG. 1, at the time of mounting the lock, the inside member 1 can be seen from the room side so that the light seen through the key groove 14 can be confirmed.
If the positioning of the outer member 2 is performed, the centering can be easily performed.

The opening position of the through hole 13 is not necessarily limited to the horizontal extension of the key groove 14, but it is not necessary to make an extra hole in the outer member 2, so that not only the appearance but also the security is improved. The use of a keyway is also preferred.

[0020]

[Effect of the invention] As is clear from the above detailed description,
In the present invention, the centering is performed by positioning the through-hole penetrating from the indoor side to the outdoor side so as to be on a straight line. It was extremely easy to match.

Also, since the centering state is checked by light rather than by looking at a specific visual object, it is possible to check clearly and easily, and it is extremely easy to mount a door lock which has conventionally been relatively troublesome. And can be performed accurately.
