CONSTITUTION:When sliding doors are in a position of shutting, an operating handle of an interior operating member installed in parallel with a lock main body 2 to a common set plate 1 is operated from the interior side. A retractor 11 is then slidden through an interlocking member 7, making a lock latch 4 emerge from a lock case 12 toward an operator or retract into the lock case 12. By operating with a key from the exterior side, the retractor 11 slides through a cylinder 14, making the lock latch 4 emerge from or retract into the lock case 12.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is attached to the central sash part of a sliding door, and can be operated from the outside by using a key to operate the cylinder. This invention relates to an improvement in a lock for a sliding door that can be locked or unlocked by operating the operating knob to cause the lock lever to move in and out, and to engage or detach from a strike provided on the opposite sash.

[Conventional technology] This type of lock for sliding doors has existed for a long time, but the lock mechanism is separated into an indoor unit oval and an outdoor unit oval, and each is installed in the sash part of the outer sliding door and the inner sliding door in a divided state. This is usually the case.

Therefore, a means is required to connect the inner and outer mechanisms during locking and unlocking operations, such as a structure in which a cylinder or an inner operating knob is provided so as to be movable in the axial direction, and when operating, the inner and outer mechanisms are connected by pushing and then rotated. Alternatively, methods were used to connect the inside and outside using the attractive force of permanent magnets.

[Problems to be solved by the invention] However, push-and-turn type sliding door locks have the drawback of not only being difficult to operate, but also being mechanically complex. Furthermore, when permanent magnets are used, if the sashes are distorted or misaligned, their mutual attraction will weaken, making it difficult to achieve a sufficient connection.

Therefore, an object of the present invention is to provide a novel sliding door lock in which the indoor operating member and the lock body are always connected, and which does not cause any hindrance to normal sliding door operation.

1. Means for Solving the Problems To achieve the above objectives, in this invention, the indoor operating member and the lock body are mounted in parallel on a common handle plate, and both are attached to the sash part of the outer sliding door. It has an oval that is built into the sash and the mounting plate is fixed to the sash surface. The cylinder of the lock body is provided with the front surface of the cylinder exposed from the outer surface of the sash so that the key can be operated from the outside, as in the conventional case.

Further, the lock body is provided with a retractor that can slide in conjunction with the key operation of the cylinder and a lock rod that can be moved out and out of the lock case in conjunction with the sliding of the retractor, as in the conventional case. Correspondingly, the mounting plate is provided with an opening into which the lock rod can be inserted and retracted, and the sash of the inner sliding door is provided with a strike into which the lock rod can be inserted and removed.

In addition, the indoor side operating member has a structure in which the operating knob can be operated from the indoor side when the sliding door is closed and is exposed so as not to prevent movement of the sliding door, and the retractor and the operating knob are always connected via an interlocking member. It was something like that.

The lock rods used for the above-mentioned horizontal sliding door locks are generally rotary lock rods such as the well-known talent type and kama type. A known deadbolt method can also be applied if a machine ellipse is used to convert the

In addition, the operating knob on the indoor operating member is generally a sliding type that matches the operating state of the retractor, but it is also possible to slide the retractor by rotating the rotary operating knob. Also, they can be connected via an interlocking member that converts a rotational movement into a sliding movement.

[Function] The sliding Toda lock according to the above configuration has the indoor a{11 operating member and the lock body mounted in a parallel arrangement on a common mounting plate, and both are always connected by the interlocking member when the outer sliding door is opened. It is installed built into the sash part and the direction of the locking force protrusion is on the indoor side where the operating knob is located, i.e. the operator's hand H.
This is related to IJil, a new configuration that has never existed before, and the indoor operating member and the lock body are always connected horizontally by an interlocking member, so when locking and unlocking, simply operate the operating knob on the indoor side. Or just insert the key into the cylinder and turn it.

Since the indoor operating member and the lock body are connected to the same sash, there is no risk that the connection between the two may become insufficient due to distortion or misalignment of the sash.

Also, since it is attached to a common mounting plate and built into and fixed to one of the sashes, installation is easy.

[Embodiment] Fig. 1 is a front view showing an embodiment of the lock for sliding doors according to the present invention, in which 1 is a common mounting plate, 2 is the lock body attached to this mounting plate, and 3 is this lock. 11 is an operating member arranged in parallel on the main body. 4 is a lock rod provided in the lock body so that it can be retracted from the lock case, 5 is an egress hole for the lock rod formed in the mounting plate 1, and 6 is a sliding operating knob provided on the indoor operating member 3. This operating knob 6 is always connected via an interlocking member 7 to a retractor slidably provided inside the lock body.

Figure 2 shows the state of the sliding door lock in the center sash part of the sliding door. In this example, the sash width W of the outer sliding door 8 is approximately 2 times the sash width W of the inner sliding door 9. With the lock body 2 and the indoor operating member 3 built into the sash portion 8a of this outer sliding door, attach the mounting plate 1 to the sash surface with screws 1.
It is fixed at 0 and installed.

Therefore, the indoor side operating member 3 is provided in an exposed state so that the operating knob 6 can be operated from the indoor side when the sliding door is closed and does not prevent movement of the sliding door.

The internal structure of the lock body 1 is as shown in FIGS. 4 and 5. In the figure, reference numeral 11 is provided so as to be able to slide inside the lock lever 12, and a bottle 13 passed through the notch 11a is passed through the hole 4a of the lock rod 4 to connect the two. When the retractor ■l slides, the lock rod 4 can come out and come out from the lock case. Reference numeral 14 denotes a cylinder, which is mounted so that the front surface of the cylinder is exposed from the four outer sides of the sash portion 8a of the outer sliding door 8 so that the key can be operated from the outside. 15 is a gear that rotates in conjunction with the rotation of the cylinder inner cylinder when the cylinder key is operated, and the retractor 11
The retractor is made to be slidable by engaging with the rack portion 1lb which is shaped like this.

17 is an 11-piece strike member attached to the sash portion 9a of the inner sliding door 9, and 18 is a long seat.

The sliding door lock according to this embodiment has the above-mentioned full structure, and when the sliding door is closed as shown in FIG. Due to the sliding movement, the lock rod 4 comes out and retracts from the lock case toward the operator's near side.

Further, from the indoor side, the retractor 11 can be operated via the cylinder 14 by key operation, and in the same way, the lock rod 4 can be moved in and out, and locking/unlocking operations can be performed.

Note that the above-mentioned lock iyi is shown as an example, and the present invention is not necessarily limited to these types.

[Effects of the Invention] As described above, the lock for a sliding door according to the present invention is a horizontal type in which the lock body and the indoor operation member are attached to the sash part of the outer sliding door by a common attachment plate, and the attachment operation is easy. It is simple, and since the two are always in a connected relationship, it is also mechanically simple, and the mechanism does not interfere with the connected relationship even if the sash is distorted or shifted. Furthermore, when locking/unlocking the vehicle, there is no need to push in the cylinder or the indoor operation knob as in the conventional case.

In other words, this invention has provided a new lock for sliding doors that eliminates all the drawbacks and difficulties of conventional locks for sliding doors in terms of mechanism and operation.
