Description

[Detailed Description of the Invention] (1) Object of the Invention (Field of Industrial Application) This invention relates to a door lock used for a door that rotates to open and close.

(Prior art and problems to be solved) A known lock attached to the end face of a door that rotates to open and close is a long plate material attached to the latch bolt that retracts from the front end face of the door when opening and closing. The length is quite long, and for this reason,
In order to attach the lock, it is necessary to form a recess of considerable depth on the end face of the door, which is a time-consuming and troublesome process. Since it is necessary to construct a part with a thickness corresponding to the depth, depending on the size of the door, only a small lock can be attached, or the frame part is abnormally large compared to the door. The necessity arose, and there were drawbacks such as being undesirable from an aesthetic point of view.

The present invention has been made in order to cope with such a situation, and makes it possible to make the structure for operating the latch bolt, dead bolt, etc. into a vertically elongated structure as a whole, thereby making it easy to attach the lock and change the usability. At the same time, the purpose is to reduce costs.

(2) Structure of the invention (technical means for solving the problem and its operation) In order to achieve the above object, the present invention provides an inside cover on the indoor side, a vertically long locking device having at least a latch bolt, and an outside cover. and a handle swingably attached to the outside cover, the handle passing through the inside cover, the locking device, and the outside cover,
A knob is arranged on the inside cover side end, the middle part engages with the latch bolt operating means, and the outside cover side end engages with a rotating cam rotatably disposed on the outside cover. a square bar-shaped spindle, a slide plate supported by the outside cover, slidable in a direction perpendicular to the longitudinal direction of the spindle, elastically deformed in one direction, and having an opening; and the handle. a hook that engages with the slide plate opening and causes the slide plate to slide by swinging of the handle; and a hook that is attached to the end surface of the rotating cam; The device is characterized in that it includes a screw that engages with an opening in a slide plate and rotates the rotary cam by sliding the plate.

With this configuration, the lock can be easily attached to the door, and the usability can be easily changed, which is also cost effective.

(Description of Embodiment) Fig. 1 is an exploded perspective view of a lock showing an embodiment of the present invention. , a cylinder lock D, and a handle device E.

The inside cover A has a hole 3 through which a spindle 2 for operating the latch bolt 1 passes, and a mounting hole 4 for mounting the cover.

When the spindle 2 for operation is attached to the above-mentioned 3, the opening 5' of the indoor knob 5 is attached to the end 2a of the spindle 2 for operation.
shall be inserted.

The locking device B is formed vertically, and a well-known mechanism (not shown) for operating the dead bolt 7 and the latch bolt 1 is housed inside the case 6, and a cylinder lock D is located at a position corresponding to the dead bolt 7.
A square hole 9 into which the spindle 2a fits is provided below the elongated hole 8 at a position corresponding to the latch bolt 1, and the spindle 2a is rotated by engaging the two. By the way,
The latch bolt 1 is made to protrude and retract from 12' of the front 11 by a well-known mechanism (not shown).

An elongated hole 14 is provided in the upper part of the outside cover C, into which a cylinder lock D is installed at a position that aligns with the elongated hole 8 during assembly, and below the elongated hole 14,
A through hole 16 is formed into which a rotating cam 15, which will be described later, fits.

Above and below the through hole 16, a handle E is attached to a shaft 17.
Support plates 18 and 18' for supporting the shaft 17 are protruded to support the shaft 17, and the shaft 17 extends through the hole 18'' provided in the support plate 18 and the through hole 19 provided in the support plate 18'. A shaft 17 is attached, and the shaft 1
A screw 20 is engaged with a recess 17' formed near the lower end of the outer cover C through a through hole 21 from the back side of the outside cover C to prevent the shaft 17 from being removed (see FIG. 2).

A through hole 16 is provided between the support plates 18 and 18'.
A recess 24 is formed so as to include the openings 29 and 29', and a slide plate 23 with openings 29 and 29' is disposed in this recess.
is deflected to the left by springs 30, 30' in the illustrated case. Reference numerals 31 and 31' are spring covers.

The rotary cam 15 fitted into the through hole 16 is provided with a square hole 25 into which the spindle 2 is fitted.
Further, the flange 26 is provided with screw holes 28, 28' into which screws 27 are screwed, and when assembled, the head 27' of this screw 27 is inserted into the openings 29,
9'.

A handle set block 33 is attached to the handle 32, and the aforementioned shaft 17 is fitted into a vertical hole 35 formed in the block 33.

Furthermore, a groove 34 is formed in the block 33, and the hooks 22, 22' are attached to the groove 34.
2 and 22' engage with the openings 29 and 29' of the slide plate 23 mentioned above.

FIG. 3 is a front view showing the vicinity of the slide plate 23 when the slide plate 23 is placed in the position shown in FIG. In this state, when the handle 32 is rotated clockwise when viewed from above in FIG. 1, the hooks 22, 22' and the openings 29, 29' are engaged, so the slide plate 23 is
The screw 27 is displaced in the direction of the arrow, and the head of the screw 27 is inserted into the opening 29.
The rotating cam 1 rotates along the edge 23' of the rotating cam 1.
5. Therefore, the spindle 2 rotates, so that the latch bolt 1 can be moved in and out of the hole 12' of the front 11 to open and close the door.

Figure 3 1 and 2 show the door on the wrong side, handle 3
This shows that when it is desired to change the direction of the pulling or pushing operation of 2, it can be easily done by reversing the slide plate 23 and replacing the screw 27 with the other screw hole 28'.

In this way, the above-mentioned locking device is constructed so that the operation of the handle is transmitted to the rotation of the spindle that moves the latch bolt forward and backward through the rotation of the rotary cam. For this reason, it is possible to form a portion of the locking device B vertically, and the entire structure of this type of lock can be formed vertically.

(3) Effects of the Invention As explained above, according to the present invention, it is possible to form the door lock to be attached to the end face of the door in a vertically elongated manner as a whole, and in order to attach the lock to the door, it is possible to form the door lock to be attached to the end face of the door. Since there is no need to form a deep recess in advance, installation is easy, and it can be easily adapted to differences in the positions of the opening and closing sides of the door, so equipment costs can be reduced.
