Abstract

The locking mechanism has an adjustable bolt (7) for a sliding door, window or similar with a bolt carrier (4). The carrier has at least one slot (5) to receive the shank (6) of the bolt, which has at least one hook (8a, 8b). The bolt carrier is designed to slide transversely relative to the slot to enable the hook(s) to engage with or disengage from a catch plate on the fixed surround of the door or window. The bolt is made so that it can be moved lengthwise in the slot to adjust its position relative to the catch plate, and it is fixed in position by means of an aperture (21) extending in the same direction as the slot and a locking screw (16) which engages with the edges of the aperture. The bolt can have either one aperture in line with its lengthwise axis or two apertures lying symmetrically relative to the axis.

Description

The present invention relates to a fitting with adjustable latch for sliding door, window or the like.

We know a fitting with adjustable bolt for sliding door, window or the like, comprising a bolt holder having at least one slot adapted to receive the tail of a bolt carrying at least a hook, the bolt holder being adapted to slide in the transverse direction of the slot to bring the latch hook engaged with a frame keeper and to release the hook from the strike, the bolt being adapted to slide in the longitudinal direction of the slot to allow adjustment of the bolt relative to said strike, the bolt holder comprising at least one threaded hole with axis perpendicular to the walls of the slot and adapted to receive a locking screw for block the tail of the bolt against the wall opposite the screw of the bolt holder slot.

This fitting is adapted to receive a bolt two hooks. The tail of the bolt has on its edges longitudinal of the teeth formed on one part only of its thickness. To be able to adjust the hook relative to a strike, in the direction longitudinal of the tail of the bolt, you need three holes formed on the outer wall of the fitting, two holes receiving bolt locking point screws and a hole for the passage of a tool to support the teeth of one of the edges to adjust the bolt in the closed position of the sash.

The presence of the three aforementioned holes weakens the bolt holder and is completely undesirable on the plan aesthetic with regard to the outer plate.

We also know, from FR-A-2,591 267 a locking fitting with adjustable bolt for sliding door. The bolt has a groove longitudinal adapted to receive an adjustment screw axis parallel to the median axis of the tail of the bolt, and which cooperates with a tapped hole made in the slot of the bolt holder which receives the tail of the bolt. The bolt has a longitudinal recess which allows access to the adjusting screw. A bolt locking screw is by elsewhere housed in an inclined tapped through hole on a side face of the bolt holder.

This fitting also involves a structure fragile of the bolt holder. In addition, the bolt adjustment is made in the open position of the opening, and it is necessary close the window to see if the position chosen for the bolt is adapted to the corresponding strike. It is necessary so proceed by successive trial and error before to arrive at a satisfactory adjustment of the bolt.

The object of the present invention is to remedy to the disadvantages of known fittings, and to propose a fitting of the aforementioned type comprising a bolt holder of solid structure suitable for receiving bolts completely reversible and to authorize, if necessary, an adjustment of the bolt in the closed position of the opening.

According to the invention, the fitting of the aforementioned type is characterized in that the tail of the bolt comprises at minus a light extending in the direction longitudinal of the slot, and in that the screw is adapted to rest on at least one of the edges of the light.

The presence of a light facilitates the deformation of the tail of the bolt under the pressure of the screw, so that a single screw is enough to ensure a satisfactory locking of the bolt tail inside from the bolt holder slot. The structure of the bolt holder does has no point of weakness. We can adapt on such a bolt holder several types of bolts completely reversible.

In the embodiment shown in Figures 1 to 3, the fitting 1 with adjustable bolt for sliding door 3, window or the like, comprises a bolt holder 4 having at least one slot 5 adapted to receive the tail 6 of a bolt 7 carrying the minus a hook 8 (see figure 2). The bolt holder 4 is suitable for sliding in the transverse direction 9 of the slot 5 for bringing the hook 8 of the bolt 7 into engagement with a keeper, shown schematically at 10 in Figure 2, and to release the hook 8 from the keeper 10.

The bolt 7 is adapted to slide in the longitudinal direction 11 of slot 5 to allow adjusting the bolt 7 relative to the striker 10.

The bolt holder 4 has at least one hole threaded 12 with axis 13 perpendicular to the walls 14, 15 of the slot 5, and adapted to receive a locking screw 16 to block the tail 6 of the bolt 7 against the wall 14, opposite the screw 16, the slot 5 of the bolt holder 4.

In the example shown, the fitting 1 comprises a housing 17 comprising an outer plate 18. The fitting 1 is fixed at each end by means of a fixing member 19 of any type to the wall 20 on the inner side of the opening 3. This structure has no compulsory character.

According to the present invention, the tail 6 of the bolt 7 has at least one light 21 extending in the longitudinal direction 11 of the slot 5, and the screw 16 is adapted to bear on at least one of the edges 22, 23 of light 21. In the example shown in detail in Figures 4 and 5, the tail 6 of the bolt 7 comprises a light 21 centered on the median axis 24 of the tail 6 bolt 7.

The longitudinal edges 22, 23 of the light 21 have teeth 25 projecting towards the opposite edge 23, 22.

The axis 13 of the screw 16 meets the median axis 24, so that the screw 16 is centered on the light 21 and rests on edges 22 and 23, and more particularly on the teeth 25 of these edges.

Conventionally, the bolt 7 has two hooks 8a, 8b projecting in opposite directions in the transverse direction 9 of the tail 6 of the bolt 7, which is confused with the transverse direction of the slot 5 receiving said tail 6.

The tail 6 of the bolt 7 is connected to the hooks 8a, 8b by a core 26 generally bent.

We have thus described a bolt completely reversible that can be inserted into the bolt holder in any way, the hooks 8a, 8b making protruding in the longitudinal direction 11 on one side any of the bolt holder 4, i.e. to the right or to left of the fitting of figure 3, any face of the bolt 4 being visible in said FIG. 3, so to offer as many solutions as possible with just one hardware and a single bolt to adapt to the structure particular of the opening and the frame considered.

It is thus possible, with a bolt extending according to a plan, and with bolts with counter-bends different, in small numbers, face substantially all possible situations of a sliding door and a corresponding frame.

In the embodiment shown in Figures 6 to 8, the light 31 opens on the edge rear 32 of the tail 33 of the bolt 34 opposite the hooks 8a, 8b. The screw 35 present at its end free adapted to come into contact with the tail 33 of the bolt 34 a tapered shape 35a pointed continuing with a cylindrical part 36 of small diameter adapted to pass between the teeth 37 formed on the longitudinal edges 38, 39 of the light 31 and ending with a flange 40 adapted to be retained on the other side of the tail 33 of the bolt 34 by compared to screw 35.

We therefore introduce the screw 35 in the bolt holder 4, then insert the tail 33 of the bolt 34 into the bolt holder, the longitudinal edges 38, 39 being inserted on the side and on the other side of the cylindrical part 36 of the screw 35, which therefore becomes captive. When we screw the screw 35, the frustoconical part 35a presses on the edges longitudinal 38, 39 and deforms these edges in the transverse direction 9 as in the direction 41 of the axis 13 from threaded hole 12 and screw 35, towards wall 14 slot 5. When you loosen screw 35, you can freely move the bolt in the direction longitudinal 11, in the open position of the opening. So we have a fitting whose bolt holder includes a single tapped hole, and which does not allow adjustment of the bolt 34 only in the open position of the door. he also suffices to loosen the screw 35 for this adjustment, without having to unscrew and extract it.

In the embodiment shown in Figure 9, which corresponds to a bolt of the type described in reference to FIGS. 4 and 5, the axis 13 of the tapped hole 12 is offset from the median axis 24 of the light 21 and the tail 6 of the bolt 7, from a distance A. It is thus possible to rest on the teeth 25 of an edge 22 of the light 21 by means of a tool (not shown) inserted in the tapped hole 12, in place of the screw 16, to move the tail 6 of the bolt 7 in the direction longitudinal 11.

This tool can be, for example, a screwdriver cruciform whose end has teeth which can engage teeth 25 to move the bolt.

The screw 16 is usually a screw, with or headless, hexagon socket with cavity female of hexagonal section adapted to receive a male tool of section adapted for the operation of the screw.

According to an advantageous version, this same screw 16 has the advantage of having a through light 27 in the direction of the axis 41, so that this light 27 allows the passage of a displacement control tool of the tail of the bolt in the transverse direction 11. This control tool is in direct contact with one or the other of the teeth 25 of one of the edges 22, 23. This cooperation between tool and teeth is not possible because of the offset of the axis of the screw with the axis center of the tail of the bolt, so that only one of edges 22, 23 is accessible by light 27.

So there is no more possible confusion between two tools, one for clamping, the other for setting. The advantage of this solution, of course, is to combine two functions on a single screw in a single threaded hole in the bolt holder 4, which is thus less fragile than in other solutions with two or more holes.

In the embodiment shown in Figures 10 to 12, the wall 45 of the slot 46 of the bolt holder 47 opposite the tapped hole 12 has a part thinned 48 having an element 49 slightly in protruding towards the inside of the slot 46. The length of element 49 in direction 9 is such that this element is flush with the tip 50 of the teeth 25 of the light 21 (see Figure 12). Because of this thinning, the projecting element 49 which cooperates with the points 50 teeth 25 is adapted to hold the tail of the bolt in position in slot 46, opposing only one force weak elastic predetermined to a displacement of the bolt 7 in the longitudinal direction 11.

The thinned wall 48 and the projecting element 49 are easily obtained, for example by molding. The thinned wall is for example obtained by sparing the corresponding recess 48a on the outer face 47a of the bolt holder 47. The projecting element 49 is by example obtained in a known manner by sparing a corresponding recess in a drawer (not shown) allowing the slot 46 to be obtained by molding.

The advantage of the element 49 projecting from the thinned wall 48, which therefore has a certain elasticity, is already able to preposition easily, by hand, the bolt 7 in slot 46, the leaf being opened.

In addition, to move the bolt 7, one can insert a tool, for example a screwdriver cruciform, in the tapped hole 12, lean on the teeth 25 to move the bolt 7 against the pressure elastic of the projecting element 49, then tighten the screw 16. The bolt setting can thus be carried out in the closed position of the opening, by means a single hole 12 formed in the bolt holder 47. The tool can also be inserted into light 27 through a screw 16 provided with such a light.

In the embodiment shown in detail in Figures 13 to 16, the tail 51 of the bolt 52 has three arms 53, 54, 55 extending from the soul 56 of the bolt 52 in the longitudinal direction 11 and spanning between them two lights 57, 58 symmetrical to each other relative to the median axis 59 of the tail 51 of the bolt 52.

As shown in particular in Figure 14, the lights 57, 58 open onto the rear edge 60 of the tail 51 of the bolt 52 opposite the core 56. The bolt holder 61 has three slots 62, 63, 64 located in the same plan and adapted to receive respectively an arm corresponding 53, 54, 55 of the tail 51 of the bolt 52.

In this example, the axis 13 of the screw 16 meets the central axis 59 of the central arm 54 and the screw 16 has a diameter larger than the width of the arm 54 and rests on both edges 54a, 54b of said arm 54. The width of arm 54 is determined so the arm 54 can deform under the pressure of the screw 16.

Each of the two outer arms 53, 55 has on an edge, for example the outer edge 53a, 55a, or the inner edge 53b, 55b, at least two notches 65, 66 opposite one another and protruding from the same side by audit report 53a, 55a, 53b, 55b in the direction transverse 9. The bolt holder 61 has a second hole 67 allowing the introduction of a tool to take support on one or other of the notches 65, 66 of the edge correspondent 53a, 55a, 53b, 55b in order to move the tail 51 of the bolt 52 in one direction or the other.

To allow the use of a single tool for adjusting, tightening and locking the bolt, and screw 16 shown being a hexagon headless screw hollow with a female section footprint hexagonal adapted to receive a hexagon key, notches 65 and 66 are configured so that each represent half of the hexagonal footprint at hexagon of said key.

In the example shown, the bolt holder 61 is made of plastic and has a metal insert 68 in which are provided the tapped hole 12 and a slot 69 adapted to receive the central arm 54 of the tail 51 bolt 52.

In the example shown in Figure 17, the latch holder 71 has two parallel slots 72, 73 to each other and spaced from each other in the direction 41 of axis 13 perpendicular to the walls of slots 72, 73.

The tapped hole 12 is adapted to receive screws 16 different lengths depending on the tail 6, 33 of the bolt 7, 34 to be blocked is located in one or the other slots 72, 73.

Of course, the present invention is not limited to the embodiments which we have just described and we can bring to these many changes and modifications without departing from the scope of the invention.
