Description

Ground locking system integrated into a door jamb

The invention relates to the field of gates, and more specifically to gates equipped with ground locks.

Most of the gates are swinging (ie pivoting) or sliding gates. In leaf gates or swing leafs manually operated, it is common to equip at least one leaf of a ground lock, which comprises a sleeve fixed to a jamb of the leaf and a bolt mounted sliding relative to the sheath between a release position in which the bolt does not exceed or little amount to allow the maneuver of the leaf, and a locking position in which the bolt exceeds the amount to come to lodge in a hole on the ground and thus lock the leaf in position closed (or, it can happen, in open position).

This technique of locking a leaf is well known. It has been improved, and thus known from EP 2 152989 (Talpe) a lock comprising a sheath housed in a jamb of the leaf, a bolt movable relative to the sheath between a release position and a locking position of the leaf , and a handle mounted on the upright and coupled to the bolt by a rack mechanism to maneuver from its release position to its locking position, and vice versa.

In theory, this solution is better than ordinary solutions, but the proposed structure, which implements a rack and pinion coupling system, is complex and fragile. Its reliability is random and its maintenance complex.

The need therefore remains to provide a locking system whose manufacture, installation, maintenance and handling are simple and reliable.

For this purpose, it is proposed, in the first place, a locking system on the ground of a gate leaf provided with a hollow upright and a vertical groove, this system comprising:

a sleeve mounted in the amount of the leaf and fixed thereon, a bolt slidably mounted relative to the sleeve between a release position in which the bolt does not exceed the amount and a locking position in which the bolt exceeds the amount for come and stay in a hole on the ground, and an operating handle of the bolt, integral with it and extending through the groove protruding from the amount regardless of the position of the bolt.

This locking system, mounted in the amount protected from the weather, is simple in structure, easy handling and efficient and reliable operation.

It is proposed, secondly, a gate comprising a leaf equipped with a system as presented above, wherein the groove is formed in an end face of the upright, perpendicular to a general plane of the leaf.

Therefore, we see that in the closed position of the gate, the handle of the bolt is not accessible (and therefore a fortiori not maneuverable) since it is trapped between the inner faces of the amounts of the leaves, which presents a big anti-theft advantage.

Various additional features may be provided, alone or in combination. So :

the handle can be mounted articulated relative to the bolt, between a rest position in which the handle extends parallel to the bolt, and a maneuvering position in which the handle extends perpendicularly to the bolt;

the handle can be pivotally mounted on an integral axis of the bolt; the handle may carry a stop which, in the operating position, comes into contact with a stop surface formed on the bolt;

the stop may be in the form of a journal fitted transversely in the handle, and the stop surface is in the form of a hollow reserve in the bolt;

the sleeve may have at least one tab folded inwards, against which the stop of the handle is applied to the approach of the lock position of the bolt;

- The handle may have a shoulder which, in the rest position of the handle and in the bolt release position, abuts against an upper bearing edge formed on the sleeve;

the sleeve may have a lower bearing edge against which the shoulder can come to rest in the rest position of the handle and in the locking position of the bolt; the bolt may have a mortise through which the handle extends.

Other objects and advantages of the invention will become apparent in the light of the description of an embodiment, given hereinafter with reference to the accompanying drawings, in which:

On FIG.1 is represented a gate 1 closing or allowing access to a property. This portal 1 is movable between a closed position in which it prohibits access to the property, and an open position in which it authorizes access to the property.

The portal 1 has at least one leaf 2. It can include two. Portal 1 is for example flying, but it could be sliding. In the following, it is described (partially) a single leaf 2. In the event that the portal 1 comprises a second leaf, it could be identical to the first. The (or each) leaf 2 extends globally (that is to say, neglecting its thickness) in a plane P.

As seen in FIG.1, the leaf 2 comprises at least one free amount 3 (that is to say an amount that describes a trajectory, eg circular when the gate 1 is flapping, or linear when the portal 1 is sliding). In the case where the gate 1 is swinging, the leaf 2 comprises another amount by which the leaf 2 is articulated on a fixed structure (such as a pillar or a column).

The free upright 3 is in the form of a square or rectangular section tube, or circular, which extends vertically in the normal mounting position (and use) of the leaf 2. As shown in FIG.1, the 3 is provided with a groove 4 made in one of its faces, and preferably an end face, perpendicular to the plane P of the leaf and which faces, in the closed position of the gate, to the other leaf when the gate 1 comprises two leaves, or to a frame when the portal 1 comprises only one leaf 2.

It is desirable to be able to lock the gate 1 at least in the closed position, and if necessary in the open position.

For this purpose, the gate 1 (and more precisely the leaf 2) is equipped with a system 6 ground locking of (or each) leaf 2, at least partially integrated with the amount of the leaf 2.

This locking system 6 comprises, in the first place, a sleeve 7 mounted in the free upright 3 and fixed thereto, e.g. by means of screws 8, as illustrated in FIG.

The locking system 6 comprises, secondly, a bolt 9 slidably mounted relative to the sheath 7 between:

a release position (FIG.7 to FIG.12) in which the bolt 9 does not exceed (or slightly exceeds) the amount 3 and

a locking position (FIG.13 to FIG.16) in which the bolt

9 exceeds the amount 3 (enough) to come to lodge in a hole 10 on the ground.

The locking system 6 comprises, thirdly, a handle 11 for operating the bolt 9, integral with it and extending through the groove 4 protruding from the upright 3 regardless of the position of the bolt 9. The sheath 7 is in the form of a profile tube and dimensions complementary (and lower) to the internal dimensions of the upright 3. In the example illustrated, the sheath 7 is rectangular horizontal section. The sheath 7 is e.g. obtained by cutting an extruded metal tubular section.

The sheath 7 has a front wall 12, through which the sheath 7 is fixed on the upright 3, a bottom wall 13 and two side walls 14 which connect them.

As can be seen in FIG. 3, the front wall 12 of the sheath 7 is provided with a slot 15 which, when the sheath 7 is housed in the upright (FIG. 1), is positioned in line with the groove 4 .

The bottom wall 13 has, in the upper part, an upper support edge 16 whose function will be explained below. In the illustrated example, the upper support edge 16 is formed by a notch 17 formed in the bottom wall 13.

The bottom wall 13 also has, at a distance from the upper support edge 16, a lower support edge 18. In the example illustrated, the lower support edge 18 is formed by a cutout 19 made in the bottom wall 13.

The bolt 9 is in the form of a metal rod. In section, the profile of the bolt 9 is circular, but it could be rectangular or square. As can be seen in particular in FIG. 3 and FIG. 4, the bolt 9 may, at a lower end, present a chamfer 20 which facilitates its centering relative to the hole 10. The bolt 9 advantageously has a mortise 21 through which extends the handle 11. This mortise 21 is advantageously formed near an upper end of the bolt 9.

The guide of the bolt 9 relative to the sheath 7 can be provided by means of fitted bearings mounted in the sheath 7, e.g. plastic low friction, typically polytetrafluoroethylene (PTFE, better known under the trade name Teflon).

However, in the illustrated example, which is distinguished by a small number of parts, the guide of the bolt 9 is provided by the sheath 7 itself, which comprises for this purpose two superimposed series of guide lugs 22 cut in a triangle in the wall 12 before and in the bottom wall 13 and folded towards the inside of the sheath 7 to form between they have a parallelepipedal opening which ensures a good maintenance of the bolt 9.

According to an embodiment illustrated in the figures, the handle 11 is articulated with respect to the bolt 9, between:

- A rest position (FIG.7, FIG.8, FIG.15 and FIG.16) in which the handle 11 extends substantially vertically, parallel to the bolt 9, and

a maneuvering position (FIG.11 to FIG.14) in which the handle 11 extends substantially horizontally, perpendicular to the bolt 9.

In the rest position, the handle 11 protrudes slightly from the sleeve 7 (and therefore from the end face of the upright 3), which allows the relative movements of the leaf 2 relative to the other leaf or relative to the frame.

In the maneuvering position, that the handle 11 adopts under the manual action of a user, the handle 11 protrudes from the sleeve 7 (and the end face 5 of the upright 3) to allow a good grip and facilitate the moving the bolt 9 from its release position to its locking position, or vice versa. More precisely, and as is clearly visible in FIG. 5 and FIG. 6, the handle 11 has, to facilitate its grip, a nose 23 which forms a projection towards the front (that is to say at the opposite the bottom wall 13 of the sleeve 7 when the locking system 6 is housed therein).

In the example illustrated, the handle 11 is pivotally mounted on an axis 24 integral with the bolt 9. This axis 9 is for example. in the form of a metal rod force-fitted into a hole 25 drilled in the bolt 9 (in this case in the vicinity of an upper end thereof), and inserted with play into a coaxial hole 26 pierced in the handle 11.

According to a preferred embodiment, the handle 11 has a shoulder 27 to come to bear:

against the upper support edge 16 of the sheath 7 to, in the absence of human manipulation, hold the bolt 9 in the release position and the handle 11 in the rest position;

where appropriate against the lower support edge 18 for, in the absence of human manipulation, and in the absence of any other constraint, keep the bolt 9 in the locking position and the handle 11 in the rest position.

According to an embodiment illustrated in the figures, and more particularly in FIG. 5 and FIG. 6, the shoulder 27 is advantageously formed by a rear lug 28 which forms a projection of a rear edge of the handle 11, so that diagonally opposite to the nose 23.

As illustrated in the figures, and in particular in FIG. 5, the handle 11 advantageously carries a stop 29 which, in the operating position, comes into contact with a stop surface formed on the bolt 9.

The stop 29 is for example. in the form of a trunnion fitted transversely into the handle 11, and more precisely, in the example illustrated, in the rear lug 28. The stop surface, for its part, is for example in the form of a hollow reserve formed in the bolt 9. In the example illustrated, the stop surface 30 faces the bottom wall 13 of the sheath 7. when the bolt 9 is there.

As can be seen in particular in FIG.14, the sheath 7 may have at least one tab 31 (and for example two tabs 31, as in the example shown) folded inwards, against which (which ) the stop 29 of the handle 11 is applied to the approach of the locking position of the bolt 9.

Each tab 31 is advantageously folded down and inclined with the bottom wall 13 at an angle of less than 90 °. As a result, when approaching the locking position of the bolt 9, the stop 29 is applied against the (or) tab (s) 31 which acts (ssen) t in the manner of a cam against which slides the stop 29, causing the handle to tilt about its axis 24, from its operating position to its rest position.

In this rocking movement, the shoulder 27 is gradually placed to the right of the lower support edge 18. At the end of the rocking movement, if nothing prevents it (especially if the bolt 9 is not at the bottom of the hole 10), the shoulder 27 is pressed against the lower edge 18 support. Therefore, the handle 11 can be released: it maintains itself in the rest position and ensures the maintenance of the bolt 9 in the locking position (if it does not rest of itself at the bottom of the hole 10) . Starting from the positions of release of the bolt 9 and rest of the handle 11 illustrated in FIG.7 and FIG.8, which allow the free movement of the leaf 2 (and thus the opening or closing of the gate 1), it proceeds as follows to maneuver the bolt 9 to its locking position (and the handle 11 to its operating position) shown in FIG.15 and FIG.16.

In the release position of the bolt 9, the lower end thereof does not exceed (or slightly exceeds) the lower end of the upright 3, to allow the maneuver (closing or opening) of the leaf 2. The handle 11, in the rest position, is supported by its shoulder 27 on the upper bearing edge 16 of the sleeve 7 and ensures the suspension of the bolt 9 (and therefore its retention) in its release position.

The handle 11 itself extends substantially vertically, the tab 28 acting against the upper bearing edge 16 of the sheath 7, in the manner of a lever which urges the handle 11 in rotation about its axis 24 towards the wall 13 of bottom of the sheath 7, so that the nose 23 certainly exceeds enough of the wall 12 before the sheath 7 (and the end face 5 of the upright 3) to allow its gripping by hand, but not enough for allow the maneuvering of the leaf 2 both opening and closing without abutting against the other leaf (or against a frame on which would come to rest the leaf 2), typically by means of a flat 32 formed on the amount 3.

From the release positions of the bolt 9 and the rest of the handle 11, the handle 11 is first grasped (in this case by its nose 23) and is pivoted about its axis 24 to move it away from the bottom wall 13 of the sleeve 7 towards its operating position, in the direction indicated by the arrow on FIG.9 and FIG.10. This movement slightly raises the bolt 9.

The rotation of the handle 11 stops itself in the operating position when the stop 29 is pressed against the stop surface provided at the rear of the bolt 9. In the maneuvering position, illustrated on FIG.11 and FIG.12, the handle 11 extends substantially perpendicularly to the bolt 9 and is substantially flush with the rear part thereof, which allows the free vertical displacement thereof in the sheath 7. While maintaining the handle 11 in its maneuvering position, the bolt 9 is accompanied in its vertical descent movement (shown by the arrow on FIG. 13 and FIG. 14) under the effect of its own weight, until that the stop 29 comes into contact with the (or) tab (s) 31 inclined (s). The bolt 9 is then already inserted in the hole 10.

When the handle 11 is released, the stop 29 acts in the manner of a cam follower which slides on the inclined lug (s) and causes, in the manner of a lever, the rotation of the handle 11 about its axis 24 towards the bottom wall 13, to its rest position, as shown in FIG.15 and FIG.16.

The bolt 9 is then in the locking position and the handle 11 in the rest position. The maintenance of these positions is ensured:

either by the bolt 9 itself if it has reached the bottom of the hole 10, or by the stop 29 against the tab (s) 31 inclined (s), as shown in the detail medallion of FIG.16 ,

either by contact of the shoulder 27 against the lower support edge 18 when it is sufficiently high (or shoulder 27 sufficiently low).

To move the bolt 9 from its locking position to its release position, the procedure is the reverse of what has just been described.

The locking system 6 which has just been described provides several advantages.

Firstly, in the closed position of the gate 1, the handle 11 is not accessible (and therefore even less manoeuvrable) since it is trapped between the end faces of the uprights 3 of the leaves 2 (or of the upright 3 of the leaf 2 and the frame), and, where appropriate, even between the flapping faces 32 of the leaves 2 joined, which makes any break more difficult.

Second, the locking system 6, housed inside the upright 3, contributes to the aesthetics of the gate 1, avoiding forming on the leaf 2 a protuberance, and is also protected from the weather, at the benefit of its reliability.

Third, the locking system 6 comprises few parts: sheath 7, bolt 9, handle 11 (including its axis 24 and stop 29). Its manufacture is simple, its easy assembly, its simple operation, efficient and reliable.
