Abstract

The bollard, designed to control access to a prescribed area, consists of a fixed socket (51) set in the ground, a mobile post (52) which can fit inside the socket or project above it, a lock (71,75) to hold the post in its raised position, and a release mechanism (61,62) operated by a key. The bollard incorporates a component (90) which holds a key retaining member (80) in its active position as the post approaches its lowest point in the socket. A second component (73) interacts with locking member (75) in the lower position to ensure reliable locking in both raised and lowered positions.

Description

The present invention relates to a lockable device for prohibiting access to a specific area. This device can in particular be a pivoting barrier or a retractable bollard in the ground, making it possible to prohibit the access of an automobile to a traffic lane or to a parking space.

• un pilier fixé au sol et un bras, solidaire d'un fût engagé sur le pilier, ce fût pouvant pivoter autour de ce pilier selon un axe vertical et sur sensiblement un quart de tour ;
• des moyens de verrouillage du bras en position de fermeture et de maintien, sans verrouillage, de ce bras en position d'ouverture, comprenant un doigt mobile entre une position de verrouillage et une position de déverrouillage ;
• des organes de manoeuvre de ces moyens de verrouillage, commandés par une clef amovible non retenue par l'organe dont elle permet l'actionnement mais seulement calée en rotation sur cet organe par simple engagement axial, et
• un organe assurant la rétention de la clef sur l'organe dont cette clef permet l'actionnement tant que le bras de la barrière n'est pas en position de fermeture, cet organe de rétention de clef étant constitué par un étrier solidaire du doigt de verrouillage précité, qui est amené en position de rétention de la clef lorsque le doigt de verrouillage est amené en position de déverrouillage.

European patent n ° 0 511 130 describes a pivoting barrier comprising:

• a pillar fixed to the ground and an arm, integral with a barrel engaged on the pillar, this barrel being able to pivot around this pillar along a vertical axis and over substantially a quarter turn;
• means for locking the arm in the closed and holding position, without locking, of this arm in the open position, comprising a finger movable between a locking position and an unlocking position;
• actuators of these locking means, controlled by a removable key not retained by the member which it allows actuation but only locked in rotation on this member by simple axial engagement, and
• a member ensuring the retention of the key on the member of which this key allows actuation as long as the arm of the barrier is not in the closed position, this key retention member being constituted by a stirrup secured to the finger of aforementioned locking, which is brought into the key retention position when the locking finger is brought into the unlocking position.

This barrier is satisfactory in practice, but has the drawback of having an arm simply maintained in the open position, without being locked. This lack of locking is troublesome in strong winds, since the arm can leave its open position and come to prevent the passage of a vehicle or + risking causing damage to this vehicle during its passage.

In addition and above all, the locking means and the key retention means described by this document cannot be used on access prohibition devices, the retractable part of which is normally recalled in the access prohibition position. This is the case for example of a terminal comprising two telescopic tubular elements which can slide relative to one another, one of which is buried in the ground and the other of which makes it possible to prohibit or free access according to that it is in the extended position or in the retracted position in the element buried in the ground. In such a terminal, in fact, the mobile element is generally returned to the extended position by an appropriate elastic means, such as a spring or a gas spring.

The present invention aims to remedy these drawbacks.

• une partie fixe, solidaire du sol, et une partie mobile par rapport à cette partie fixe entre une position interdisant l'accès et une position permettant l'accès ;
• des moyens de verrouillage de ces deux parties en position interdisant l'accès, incluant un organe de verrouillage mobile entre une position de verrouillage et une position de déverrouillage ;
• au moins un organe de manoeuvre de ces moyens de verrouillage, commandé par une clef amovible non retenue sur l'organe dont elle permet l'actionnement mais seulement calée en rotation sur cet organe par simple engagement axial, et
• un organe assurant la rétention de la clef sur cet organe de manoeuvre tant que les deux parties du dispositif ne sont pas en position interdisant l'accès.

The device which it concerns comprises, in a manner known per se:

• a fixed part, integral with the ground, and a part movable relative to this fixed part between a position preventing access and a position allowing access;
• means for locking these two parts in a position preventing access, including a movable locking member between a locking position and an unlocking position;
• at least one member for operating these locking means, controlled by a removable key which is not retained on the member, the actuation of which it allows, but only locked in rotation on this member by simple axial engagement, and
• a member ensuring the retention of the key on this operating member as long as the two parts of the device are not in the position preventing access.

• des moyens permettant, avant que ladite position permettant l'accès soit atteinte, le maintien de l'organe de rétention de la clef en position active, puis, lorsque cette position est atteinte, le mouvement de l'organe de verrouillage par rapport à l'organe de rétention de la clef, entre deux positions distinctes, et
• des moyens coopérant, dans cette même position permettant l'accès, avec l'organe de verrouillage pour assurer, dans l'une des deux positions distinctes précitées de cet organe de verrouillage, le verrouillage des deux parties du dispositif et, dans l'autre de ces deux positions distinctes, le déverrouillage de ces deux parties.

According to the invention, the device comprises:

• means allowing, before said position allowing access is reached, the maintenance of the key retention member in the active position, then, when this position is reached, the movement of the locking member relative to the '' key retention device, between two distinct positions, and
• cooperating means, in this same position allowing access, with the locking member to ensure, in one of the two distinct positions mentioned above of this locking member, the locking of the two parts of the device and, in the other from these two distinct positions, unlocking these two parts.

Thus, the locking member is not integral with the key retention means, as is the case in the aforementioned European patent, but is freely movable relative to these means in the position allowing access. In this position, the locking member can therefore be moved so as to ensure locking of the two parts of the device, while the key retention member is kept in the active position by the means provided for this purpose.

Locking the two parts of the device in position allowing access prevents any movement of the mobile part of the device in this position. The risk of the barrier arm pivoting into the open position in the event of wind is therefore eliminated. In addition, this possibility of locking in position allowing access makes it possible to adapt a member ensuring the retention of the key to a device comprising a movable part normally recalled in the position preventing access.

Preferably, the device comprises means making it possible to automatically bring the locking member into the position ensuring locking when the two parts of the device reach the position. allowing access. The user thus has no action to perform in order to lock the device in this position allowing access.

• Figure 5 is a view of this terminal similar to Figure 4, in a position allowing access.

Figures 1 and 2 show, from different angles, a pivoting barrier 1, comprising a pillar 2 fixed to the ground and an arm 3, integral with a barrel 4 engaged on the pillar 2. This barrel 4 can pivot around this pillar 2 along a vertical axis and over substantially a quarter turn, to allow the opening and closing of the barrier 1.

The pillar 2 comprises an upper plate 5 pierced with two holes 6,7, arranged at an angle of 90 ° relative to each other, and, near the hole 7, an arcuate wall 8 forming a ramp. The relative arrangement of these holes 6,7 and wall 8 will be explained below.

The barrel 4 comprises, fixed to its peripheral wall 4a, a radial partition 10 which comes to rest on the plate 5 and which can pivot relative to it.

This partition 10 comprises a barrel 11 and a plate 12 for retaining a key 13 for maneuvering, pivotally mounted relative to it.

The barrel 11 has an axial stud 15 with a prismatic profile and the lateral wall 4a of the barrel 4 comprises a hole 16 arranged opposite this stud 15. As shown in FIG. 2, this hole 16 allows engagement and setting in rotation on the pad 15 of the operating key 13, the latter comprising an enlarged end 13a delimiting a triangular imprint of shape corresponding to that of the pad 15.

The barrel 11 is also integral with a rod 20, fixed on it in a substantially tangential manner, which is engaged through a slot 21 arranged in a vertical finger 22. This finger 22 can be engaged and can slide in the one or other of the holes 6,7 for locking the barrier 1 in two positions of the arm 3 at 90 ° from each other, corresponding to the open position and the closed position of the barrier 1, and can be lifted, by pivoting the barrel 11 and the rod 20, above the plate 5, to allow the passage of the arm 3-barrel 4 assembly from one position to the other of the barrier 1.

In the raised position, the finger 22 remains engaged through a guide plate 23, fixed to the partition 10.

The plate 12 comprises a pin 24 which can be engaged and pivot in a stud 25 integral with the partition 10, the plate 12 can thus pivot in a vertical plane between a lowered position, shown in FIG. 1, and a raised position. On the side of the peripheral wall 4a, this plate 12 comprises a pin 26 on which is engaged one end of a spring 27, of which the other end is engaged on a pin 28 secured to the partition 10. This spring 27 allows the plate 12 to be returned to the lowered position.

On the side of the stud 25 opposite the wall 4a, the plate 12 comprises a notch 30 arranged in its upper edge, opposite the stud 15, a finger 31 and a rounded lower edge 12a.

The notch 30 is shaped to allow the passage of the key 13 when the plate 12 is in the lowered position, but to retain the enlarged part 13a of this key 13 in the raised position of this plate 12.

The finger 31 projects from the free end of the plate 12, parallel to the axis of the stud 25, and comes to rest on the part of the rod 20 protruding from the lumen 21.

The arcuate wall 8 is located on the path followed by the plate 12 during the pivoting of the arm 3 of the barrier, so that the rounded lower edge 12a of this plate 12 comes, in the open position of the barrier 1, as shown Figure 2, engage and slide on this wall 8.

The height of this wall 8 is such that it keeps the plate 12 in the raised position.

As shown in Figure 1, the barrier 1 is locked in the closed position by engagement of the finger 22 in the hole 6. The plate 12 is then in the lowered position and allows the engagement of the key 13 on the pad 15. The pivoting of the key 13 allows pivoting of the barrel 11 and, consequently, the lifting of the rod 20, which simultaneously causes the lifting of the finger 22 above the plate 5 and the lifting of the plate 12 in the key retention position 13.

The arm 3-barrel 4 assembly can then pivot a quarter of a turn towards the opening position of the barrier 1, shown in FIG. 2. Before the arm 3 arrives in this opening position, the lower edge 12a of the plate 12 engages on the arcuate wall 8, which allows the plate 12 to be held in the raised position and the vertical movement of the finger 22 relative to this plate 12.

When the arm 3 arrives in the open position, the finger 22 falls into the hole 7 by gravity, and ensures the locking of the arm 3-barrel 4 assembly in the open position of the barrier 1.

To bring the barrier 1 back to the closed position, the key 13 is actuated so as to lift the finger 22 in order to extract it from the hole 7, then the arm 3 is pivoted until the finger 22 comes again. engage in hole 6.

FIG. 3 represents a terminal 50 comprising two telescopic tubular elements 51, 52, one of which, designated by the reference 51, is buried in the ground and the other, designated by the reference 52, makes it possible to prohibit or release a access depending on whether it is in the extended position or in the retracted position in the element 51.

A gas spring (not shown in this figure for the sake of clarity) bears against the bottoms 51a, 52a of these two elements 51, 52, and allows the element 52 to be returned to the extended position.

The bottom 52a comprises two studs 55, each of which is secured to a side plate 56, itself secured to a finger 57 fixed to a transverse plate 58.

The transverse plate 58 supports an upper barrel 61 secured in rotation to a lower axial tube 62 by means of plates 63.

The barrel 61 comprises a triangular stud 65 similar to the aforementioned stud 15 and a stud 66 projecting radially outwards.

The tube 62 is engaged and can slide in a tubular wall 70 integral with the bottom 51a, comprising an upper notch 71, a longitudinal slot 72 and a lower notch 73 communicating with each other. The tube 62 comprises a lower tab 75 projecting radially, which can be engaged and slide in one or the other of these notches 71, 73 and in the longitudinal slot 72.

An upper ring 76, secured to the fingers 57, and a lower ring 77, secured to the side wall of the element 52 by means of a curved arm 78 engaged in the slot 72, guide the tube 62 in translation .

One of the side plates 56 comprises a key retention plate 80 as mentioned above, allowing the retention of a key 13 on the barrel 61. As is more particularly visible in FIGS. 4 and 5, this plate 80 comprises a pin 81 forming a pivot, allowing it to pivot in a horizontal plane, a pin 82 for mounting one end of a return spring 83 and a notch 84 similar to those described with reference to Figures 1 and 2, while the plate 56 comprises a pin 85 for mounting the other end of the return spring 83, also similar to the pin 28 described with reference to FIGS. 1 and 2.

It appears in Figures 4 and 5 that the plate further comprises a vertical finger 90 on its edge opposite the notch 84, located outside the internal perimeter of the circular wall 70 when the plate 80 is in the inactive position (Figure 4) , and located inside this perimeter when said plate 80 is in the active position (FIG. 5).

When the terminal 50 is in the access prohibition position, the tab 75 is engaged in the notch 71 and the plate 80 for retaining the key 13 is kept in the inactive position by the return spring 83.

The engagement of the key 13 on the stud 65, through a hole (not visible in the figures) arranged in the bottom 52a, and the pivoting of this key 13 allow the barrel 61 to pivot, and therefore to drive the tab 75 out of the notch 71 and, simultaneously, by pressing the stud 66 against the pin 82, to pivot the plate 80 in the active position. The element 52 can then be slid in the element 51, against the elastic return force of the gas spring, until the tab 75 is located opposite the notch 73.

Before the arrival of the tab 75 in this position, the finger 90 engages in the cavity delimited by the circular wall 70 and comes to bear against the internal face of this wall 70, which makes it possible to maintain the plate 80 in position of retention of the key 13 and makes possible the movement of the barrel 61, and therefore of the tab 75, independently of the movement of this plate 80.

The key 13 can then be pivoted so as to bring the tab 75 into the notch 73, as shown in FIG. 5.

This key 13 is thus retained on the barrel 61 by the plate 80 as long as the elements 51, 52 have not returned to the position preventing access.

It goes without saying that the invention is not limited to the embodiments described above by way of examples but that it embraces, on the contrary, all the variant embodiments. Thus, the lockable device which it relates to may not be a pivoting barrier or a retractable terminal, but a tilting easel or, in general, any other device making it possible to prohibit access to a determined area.

In addition, means can be provided for automatically bringing the locking member (finger 22 or tab 75) into the locking position, when the device is in a position allowing access, such as, in particular, a spring.
