TITLE: LOCKING DEVICE FOR A LOCK, ESPECIALLY FOR FRAMES OF SLIDING DOORS!

DESCRIPTION

The present invention relates to a locking device for a Lara greenhouse, particularly for counterframes of retractable sliding doors.

Nowadays it is known to create the trouble! they provide for the use of a counter frame, positioned around a wall, within which a door or a panel is slidingly associated, which is also referred to as a "retractable door".

This solution makes it possible to reduce the overall dimensions of the door inside a room thanks to the possibility of making it slide within the counter frame: it is thus possible to use the space adjacent to the door which would instead be occupied by doors of the type hinged laterally to a cassamatta. .

note the drowned subframe r_ol wall usuaime :; it consists of a frame comprising a plurality of vertical profiles, a front upright or a rear upright connected by horizontal crosspieces defining a box for containing the panel or door.

Superiorrrer.te the box protrudes, according to an axis longitudinal to the box itself that develops on the opposite side to the containment box, a track that is hidden by a jamb.

Trolleys are slidingly associated within the track and are constrained to the upper edge of the door to allow it to slide inside and outside the counter frame.

A further upright ir is usually associated with the end of the track not associated with the vertical uprights, which acts as a terminal for the stop and abutment of the front edge of the door.

Such known types of door and window frames therefore use metal profiles Lia which can be assembled and sold for example in assembly kits.

The door is usually associated with a lock of the type consisting of a hook, shaped like a hook, which is allowed an oscillating movement such as to allow it to be temporarily hooked in correspondence with a tooth present on the rabbet frame for said door.

Patent EP2889443 is known which describes a closing system for counterframes of sliding doors of the type described above.

A drawback that is encountered in the noe a technique consists in the flap that the striker is fixed by screwing them directly onto the door jamb or jamb box, and cannot consequently be adjusted.

Sliding doors may in fact require height adjustments due to system settlements after assembly, or due to an incorrect measurement at the time of installation, or in the event that the striker has been fixed at a slightly offset height with respect to the hook for the lock, or in case you want to raise the level of the floor, after assembling the door.

To try to solve the problem, it is necessary to change the fixing position by screwing a screw above the existing hole, a few millimeters away.

A drawback that is encountered in the known art consists in the fact that the pin tends to move towards the previous shaft, thus compromising the tightness of this coupling pin which would be poor and unstable.

The aim of the present invention is to eliminate the aforementioned convenient 1 "by realizing a locking device for a lock, particularly for counterframes of retractable sliding doors, which can be easily and quickly adjusted.

Within the context of the conception described above, an object of the present invention is to obtain a locking device which is adjustable without changing the initial fixing position.

A last object is to obtain an invention which is overwhelmingly simple, which has low manufacturing costs and can be produced with the usual known systems.

The task and the aforementioned purposes, as well as others which will appear more clearly later on, are achieved by a locking device (1) for a lock (?), A particular element for counterframes of retractable sliding doors, which is characterized by the fact that it is constituted by a box-like body (131 a crai is rotatably associated with an eccentric pin (17), which can be activated by the user, cooperating with a slide (19), movable inside said box-like body (13), from which a coupling pin (15) protrudes ), adjustable, cooperating with said lock [?).

furthermore, it should be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is meant not to be resold and object c: the excerpt (disclaimer) from the claims.

With reference to the Ligurian previously mentioned, the number (1) refers to a locking device for a lock (2), particularly for counterframes of retractable sliding doors (not shown).

The lock: 2) consists of a box-like structure (3) with a parallelepiped shape, with door 53u on one side and closable by means of a lid (not shown) and connected at the front by a front panel (4), with first holes (5a, 5b ) for coupling to the door.

Within the box-like structure (3) there is a means for engaging a coupling pin (15) for example from a cylinder (6), open at one end and closed at the other by a presetiLant wall (7) and axially a pin (3; lu ing to the rear bulkhead (9) de11 with box-like structure (3).

The cylinder (6) is thus rotatably associated idle with the box-like structure (3) and prerequisites a lateral surface (1C) which, during rotation, touches the internal surface of the front panel (4; and has at least a first hole (11) which can be facing an opening frame (12) obtained on the troncalino (4).

The locking device (1) consists of a scapular body (13), having a substantially cylindrical shape with a circular base, on which a first through axial seat (14) is obtained, in plan having a substantially oval shape with a major axis arranged along a diametrical axis to that of the box-like body (13), within which the coupling pin (1b) slides slidingly.

On the box-shaped body (13) there is also a second through axial seat (16), in plan having a substantially circular stop and a sequentially different rear view, within which an eccentric pin (17) rotatably insists, said second axial seat (16) being obtained in an area adjacent to said first axial seat (14).

On the box-shaped body (13) there is also obtained, according to an axis perpendicular to that of said first and second axial brackets (14,16), a third passing seat (18) whose axis is therefore parallel to the one or greater that will provide the first seat (11).

Said third seat (18) has a substantially oval shape in plan, with a major axis obtained along a perpendicular axis to the major one of said first seat (14) and which intercepts said first and second axial seats (14,16); moreover, said third seat (18) has a conical shape in a section passing through said major axis.

The first and second axial seats (14,16) are parallel to each other, while the third seat (18) is perpendicular to the previous ones.

A slide (19) is positioned inside said third seat (18) which is allowed both an axial displacement and a partial rotation in the area affected by said eccentric pin (17), presenting the third seat (18) with a suitable width.

The coupling pin (15) has a first threaded stem (20) rotatably fixed to said slide (19) and has a first head (21) protruding beyond the end of said first axial seat (14) facing the front plate (4 ) of the lock (2).

The box-shaped body (13) advantageously has, in the direction of said front panel (4), a flat base (22) with a larger diameter yes; wherein a pair of second zeros (23a, 23b) is obtained for its fastening to a frame or strike bar for said door in an area adjacent to said opening (12) obtained on the front panel (4).

The eccentric pin (17) has a second head (24), rotatably associated with a substantially cylindrical fractional counter-shaped (25a) of said second axial seat (16) adjacent to said flat base (22), a notch (26) adapted to be affected for example by the cutting tip of a tool such as a screwdriver.

The second head (24) is advantageously obtained a notch and annular curb (30) for a spring (31) projecting radially from it and interacting with a pre-arranged housing (32) obtained on the facing lateral internal surface of said first section (25a ) of said second axial seat (i6); the spring increases the friction for the rotation of said eccentric pin (17).

For the insertion of the spring (31) it may advantageously be provided to obtain a hole for its placement in correspondence with the box-like body (13), possibly then locked by means of a grain.

Contiguous to the second head (24) there is a second shank (27), substantially cylindrical, with a smaller diameter and offset with respect to said second head (24).

The second stem (27) is rotatably associated in correspondence with a second substantially cylindrical one (2b) of said second axial seat (16) which is offset with respect to said first shaft (25a).

Contiguous to said second shank (27) there is a third shank (28), substantially: cylindrical, with a smaller diameter than said second shank (27), which is in axis with said second head (24) and insists in correspondence with a third section (25c), substantially cylindrical, of said second axial seat (16) which mounts in axis with said first section (25a).

The terminal end (2 (3) of said third shank (2fi) has a larger diameter and is elastically and radially compressible for snap coupling in correspondence with a predisposed fourth plow (25d), substantially cylindrical, of said second seat axial (16) contiguous to said third portion (2oc), in axis with the latter but with a larger diameter than it to define a step discontinuity for the temporary anchoring of said terminal end (29).

the use of the device is as follows: once assembled and inserted in correspondence with a steel or striking plate for said door in an area adjacent to said opening (12) obtained on the front panel (4) of the lock, the user can, acting on the slot (26) of the pin eoc: enters oc vary in the position of the first head (zi) up to oh and the same is aligned with the first hole [11; obtained on the lateral surface (10) of the cylinder (6) constituting the lock (2).

It is thus possible to achieve the subsequent optimal and rapid closing-opening of the sliding door by compensating for the settling of the system after the assembly of the sliding door, or if the door has been badly adjusted at the time of installation, or again because it has been successful. When assembling the door, cover the floor with an additional pre-f floor: given that this particular solution requires the door to be raised a few millimeters

It has thus been found that the object of the invention has been achieved; however, a locking device for a lock has been obtained, particularly for counterframes of retractable sliding doors, which can be adjusted in height easily and quickly without modifying the initial fixing position or the positioning of the door. The invention is naturally susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.

Natura_monte, the materials used as well as the dimensions constituting the single components of the invention may be several combs according to the specific requirements.

he characteristics that indicate Le as advantageous, convenient or similar, may also be missing or be replaced by the equivalent.
