Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention includes at least one control rod and at least one locking tongue that is adjustable in the transverse direction by moving along a horizontal groove in the control rod. It relates to a locking device for sliding doors such as windows and doors that is incorporated into the control rod.

[Conventional technology]

A locking device for a sliding door such as a window, a door, etc., comprising at least one control rod and incorporating at least one locking tongue adjustable in the transverse direction by moving along a horizontal groove of the control rod. GB-A
-Already known from No. 1396876. The device includes two device halves with flanged edges pushed into openings formed in opposite sides of the vertical frame of the sliding door; Screw into the threaded protrusion on the device half,
Its head is kept assembled by inwardly directed screws.

One half of the device is provided with a guide path for guiding the vertical movement of the control stick. There is a protrusion on the back side of the control rod, and the horizontal groove is formed in this protrusion. A row of teeth is formed on the lower edge of this horizontal groove to engage with the teeth formed on the underlingual surface of the lock. After this locking tongue is placed, the locking tongue is fixed with a fixing screw that is inserted into the slit formed in the locking tongue and screwed into the screw hole of the control rod. At that time, the tightening direction of this fixing screw is This is the opposite direction to the tightening direction of the assembly screws of both device halves.

[Problem that the invention seeks to solve]

However, with the locking device known from the above-mentioned document, the lock tongue cannot be adjusted without disassembling the locking device. That is, in order to adjust the position of the lock tongue,
The user first removes the half of the device including the control rod by unscrewing the assembly screw, then removes the lock tongue from the horizontal groove of the control rod by unscrewing the fixing screw, and then removes the control rod. The locking tongue must be repositioned into engagement with the horizontal groove, the locking screw must be tightened, and the device halves must then be assembled. These operations obviously complicate the adjustment or replacement of the locking tongue of the locking device.

The object of the invention is to propose a locking device for a sliding door which includes means accessible from the side of the sliding door, allowing continuous adjustment.

[Means for solving problems]

Therefore, the present invention includes at least one control rod, and the control rod is provided with at least one locking tongue that is adjustable in the transverse direction by moving along a horizontal groove of the control rod. The present invention relates to a locking device characterized in that the locking device includes an adjusting device between a control rod and a locking tongue, including an adjusting screw provided in the locking tongue and moving axially together with the locking tongue.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

A locking device for a sliding door such as a window or door mainly consists of two device halves 1 placed on both sides of the sliding door, each device half 1 including a fixing plate 2 pressed against the surface of the sliding door. Various elements protruding from the inner surface 3 are housed within the hollow frame of the sliding door. The two device halves 1 are maintained in the assembled state by a fixing element, such as a screw, which passes through the orifice 4 of one device half 1 and threads into a threaded projection projecting from the inner surface of the other device half. has been done.

However, only the device half 1 containing the device that makes it possible to adjust the traversal amount of the locking tongue 5 is shown and described as an embodiment of the invention.

The device half 1 has an inner surface 3 of a fixed plate 2 guided by two parallel partitions 7, 8 integral with said inner surface 3.
It includes a control rod 6 that slides along. This control stick 6
can be operated by a puller 9 accessible through a slit 10 formed in the fixing plate 2.
A locking tongue holder 11 connects the locking tongue 5 and the control rod 6 and is provided with the same displacement movement as the control rod 6 since it is an integral part of the control rod.

A horizontal groove 12 is formed in this lock tongue holder 11, along which groove the lock tongue 5 moves in the transverse direction.

An adjustment device 13 is interposed between the lock tongue holder 11 and thus between the control rod 6 and the lock tongue 5.

See also Figure 4.

The adjusting device 13 is arranged in the lock tongue 5 and consists of an adjusting screw 14 that is integrally displaced therewith.

In the first embodiment, a cavity 15 is provided in the lock tongue 5,
An adjusting screw 14 is placed therein. The adjusting screw has the form of an externally threaded cylinder. Said cylindrical screw cooperates with a screw hole 16 formed in the horizontal groove 12. The depth of the screw hole 16 corresponds to the width of the lock tongue holder 11, so that said screw hole 16 communicates with both sides 17, 18 of the lock tongue holder 11, and the adjusting screw 14
installation. In order to operate the adjusting screw 14, said adjusting screw 14 is provided with gripping means. A hexagonal hole 19 is formed as this gripping means, and a hexagonal hole 19 is formed therein.
It is only necessary to engage the ends of the square nut/spanner 21. In another embodiment, this gripping means is a groove formed in the end of the adjusting screw 14 facing the side of the sliding door, into which the end of the screwdriver engages.

In order to access the adjusting screw 14, a slit 22 is provided which reaches into the cavity 15. In the first embodiment, this slit 22 is a central slit and is located in the vertical central plane of the lock tongue 5. This central slit reaches the sides of the lock tongue 5. In this case, the locking tongue 5 must have a certain degree of thickness.

In a second embodiment, the locking tongue 5 comprises a discontinuity 24, so that the hooks 25, 26 are offset with respect to the shank 27, and the slit 22 is located at the discontinuity 24.
It has reached this point.

That is, depending on the pitch of the adjusting screw 14, the lock tongue 5 is continuously moved from the side of the sliding door across the central slit, or in the case of a lock tongue with a biased hook, across the slit up to the discontinuous portion 24. can be adjusted to

In order to prevent the locking tongue 5 from shifting sideways unexpectedly, a restraining means is incorporated into the locking device. This blocking means is preferably formed by a blocking screw 28 whose free end 29 forms a cone 30 and which acts on one side 31 of the locking tongue 5 to push the locking tongue 5 into the horizontal groove.
2 and fixed to the side wall 32 on the opposite side.

In FIG.
1 to move the locking tongue 5 to the upper side wall 32 of the horizontal groove 12.
Press and fix to. However, the locking screw 28 is
Even if the locking tongue 5 is fixed to the lower side wall of the horizontal groove 12 by pressure acting on the upper side surface, the effect is equivalent.

In order to achieve a more complete cooperation between the conical free end 29 of the locking screw 28 and the side surface 31 of the locking tongue 5, the locking tongue holder 11 is formed with an inclined threaded hole 33 that reaches the side surface 18 of the holder 11. If you do this,
It is also possible to operate the stop screw 28 from the side of the sliding door.

To obtain reversibility, inclined screw holes 33, 34 are formed in each side 17, 18.

Although the present invention has been described above based on a specific embodiment, the present invention is not limited to this embodiment, and the shapes, materials, and changes in these elements may be modified without departing from the scope and spirit of the present invention. It goes without saying that various changes can be made to the combination.
