Description

Lockable device that prevents the Access in a certain area.

The present invention relates to a device Lockable that prevents access to a certain area. This device may in particular be a pivoting barrier or a retractable cairn on the ground, which prevents access from a car to a traffic lane or to a location of parking lot.

European patent EP-A-0.511.130 describes a barrier pivoting comprising:

-

a pillar fixed in the ground and an arm, integral with a body coupled on the pillar, this body can pivot around this pillar along an axis vertically and about a quarter turn;

-

a means of arm lock in closed and maintenance position, without lock, of this arm in the open position, comprising a moving finger between a locked position and a position of unlocking

-

some organs of maneuver of these locking means, sent by a removable key not retained by the organ of which it allows the drive but only draft in rotation on this organ by simple axial introduction, and

-

an organ that ensures the retention of the key on the organ of which this key allows the drive while the barrier arm is not in closing position, this key holding member being constituted by a supportive footboard of the aforementioned blocking finger, which is brought to the key retention position when the finger of Lock is brought to the unlocked position.

This barrier is satisfactory in practice, but it has the disadvantage of having a simply maintained arm in the open position, without being locked. This absence of blocking it is annoying in case of violent wind, since the arm can leave its opening position and prevent the passage of a vehicle or run the risk of causing damage to this vehicle when Your step takes place.

In addition and above all, the blocking means and the key retention means described by this document cannot be used in access prohibition devices whose retractable part is normally brought to the position of access prohibition Such is the case, for example, of a landmark It comprises two telescopic tubular elements that can slide one with respect to the other, of which one is sunk in the ground and of which the other allows to prevent or release access according to be in the starting position or in the entry position in the element sunk in the ground. In such a milestone, in fact, the mobile element is generally brought to the starting position by a appropriate elastic medium, such as a spring or a gas jack.

The present invention envisages avoiding these inconvenience

The device to which it refers comprises, of known way:

-

a fixed part, solidarity of the ground, and a mobile part with respect to this part fixed between a position that prevents access and a position that allows access;

-

a means of blocking of these two parts in position that prevent access, which they include a mobile locking member between a locking position and an unlocked position;

-

at least one maneuvering organ of these locking means, sent by a key removable not retained on the organ of which allows the drive but only rotating draft on this organ by simple axial introduction, and

-

an organ that ensures the retention of the key on this maneuvering organ in both the two parts of the device are not in a position that prevents the access.

According to the invention, the device comprises:

-

means that allow, before said position that allows access is reached, the maintenance of the key retention body in active position and then when this position is reached, the movement of the locking member with respect to the holding member of the key, between two different positions, and

-

means that cooperate, in this same position that allows access, with the locking device to secure, in one of the two positions different cited above from this blocking body, the blocking of the two parts of the device and, in the other of these two different positions, the unlocking of these two parts.

Thus, the blocking organ is not in solidarity with the key retention means, as is the case in the patent European cited, but is freely mobile with respect to these means in position that allow access. In this position, the blocking organ can therefore be displaced so that ensure a blockage of the two parts of the device while the key retention device is kept in active position by the means provided for this purpose.

The blocking of the two parts of the device in position that allows access prevents any movement of the moving part of the device in this position. The risk of pivoting the arm of a barrier in the open position in Wind case is therefore eliminated. In addition, this possibility of lock in position that allows access makes adaptation possible of an organ that ensures the retention of the key in a device comprising a moving part normally taken to the position that prevents access.

Preferably, the device comprises means that allow to automatically carry the blocking organ in position that ensures the blockage when the two parts of the device reach the position that allows access. The user It does not have any action to perform to block the device in this position that allows access.

For your best understanding, the invention is described again below with reference to the schematic plane Annex representing, by way of non-limiting examples, two possible embodiments of the lockable device to which refer.

Figure 1 is a partial, perspective view and with starting, of a pivoting barrier in a prohibition position of access;

Figure 2 is a partial view of this barrier, in section according to line II-II of figure 1, in position that allows access;

Figure 3 is a view, in perspective and with torn off, from a marker with the mobile element retractable in the soil, in a position of prohibition of access;

Figure 4 is a view of this marker, in section according to line IV-IV of figure 3, in access prohibition position, and

Figure 5 is a view of this marker similar to Figure 4, in position that allows access.

Figures 1 and 2 represent, from different angles, a pivoting barrier 1, comprising a pillar 2 fixed to the floor and arm 3, integral with a body 4 coupled on the pillar 2. This body 4 can pivot around this pillar 2 according to a vertical axis and about a quarter turn, for allow the opening and closing of the barrier 1.

Pillar 2 comprises an upper stage 5 drilled by two holes 6, 7, arranged at an angle of 90 ° one with respect to the other and, in the vicinity of the hole 7, a arched wall 8 that forms a ramp. The relative provision of These holes 6, 7 and wall 8 will be explained later.

The body 4 comprises, fixed on its wall peripheral 4a, a radial partition 10 that goes to rest on the stage 5 and which can pivot with respect to it.

This partition 10 comprises a keg 11 and a retaining plate 12 of a maneuvering key 13, mounted pivoting on said partition.

The barrel 11 has an axial pivot 15 with prismatic profile and the side wall 4a of the body 4 comprises a hole 16 made on the face of this pivot 15. As the Figure 2, this hole 16 allows the introduction and draft in rotation on pivot 15 of the operating key 13, this comprising a widened end 13a delimiting a triangular cavity corresponding to that of pivot 15.

The barrel 11 is also integral with a rod 20, fixed on it in a substantially tangential way, which is coupled through a port 21 practiced on a vertical finger 22. This finger 22 can be introduced and can slide on one or another of the holes 6, 7 to ensure the blocking of the barrier 1 in two positions of arm 3 at 90º from each other, which correspond to the open position and the closed position of the barrier 1, and can be raised, by pivoting the barrel 11 and the rod 20, by on top of stage 5, to allow the arm assembly to pass 3-body 4 from one position to the other of the barrier one.

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

The plate 12 comprises a pivot 24 which can be introduced and pivot in a pivot 25 integral with partition 10, the plate 12 can thus pivot in a vertical plane between a lowered position, represented in figure 1, and a position high. On the side of the peripheral wall 4a, this plate 12 has a pin 26 on which an end of a spring is coupled 27, the other end of which is coupled on a shank 28 of the partition 10. This spring 27 allows the return of the plate 12 to The lowered position.

On the side of the pivot 25 opposite the wall 4a, the plate 12 comprises a recess 30 made at its edge upper, in front of pivot 15, a finger 31 and a lower edge 12a rounded.

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

Finger 31 forms a free end of the plate 12, parallel to the axis of pivot 25, and goes to rest on the part of the rod 20 protruding from the port 21.

The arched wall 8 is located on the path that plate 12 follows when pivoting takes place of arm 3 of the barrier, so that the lower edge rounded 12a of this plate 12 passes, in the open position of the barrier 1, as shown in figure 2, to engage and slide on this wall 8.

The height of this wall 8 is such that it allows keep plate 12 in an elevated position.

As Figure 1 shows, barrier 1 is locked in closed position by inserting finger 22 in the hole 6. Plate 12 is then in the lowered position and allows the introduction of the key 13 on the pivot 15. The pivot of the key 13 allows pivoting of the keg 11 and, as consequently, the raising of the stem 20, which causes simultaneously raising finger 22 above deck 5 and the elevation of the plate 12 in the key retention position 13.

The arm 3-body assembly 4 can then pivot in a quarter turn towards the opening position of the barrier 1, shown in figure 2. Before the arrival of the arm 3 to this opening position, the lower edge 12a of the plate 12 engages on the arched wall 8, which allows the maintenance of the plate 12 in an elevated position and the vertical movement of the finger 22 with respect to this plate
12.

Upon arrival of arm 3 in the open position, finger 22 falls into hole 7 by gravity, and ensures blockage of the 3-body 4 arm assembly in the position of barrier opening 1.

To bring barrier 1 in the closed position, the key 13 is actuated so as to raise the finger 22 in order to remove it from hole 7, and then arm 3 is pivoted until finger 22 goes back into the hole 6.

Figure 3 depicts a marker 50 comprising two telescopic tubular elements 51, 52, of which one, designated by reference 51, is sunk in the ground and of the that the other, designated by reference 52, allows to prevent or release an access depending on whether it is in the starting position or in the position entry in item 51.

A gas jack (not shown in this figure a clarity purposes) is supported against funds 51a, 52a of these two elements 51, 52, and allows the return of element 52 to the position exit.

The bottom 52a comprises two pivots 55, of which each one is in solidarity with a side stage 56, in turn solidarity of a finger 57 fixed to a transverse plate 58.

The transverse plate 58 supports a kite upper 61 rotated to a lower axial tube 62 thanks to platelets 63.

The barrel 61 comprises a triangular pivot 65 similar to the aforementioned pivot 15 and a stud 66 that forms protrusion radially outward.

The tube 62 is coupled and can slide in one tubular wall 70 integral with the bottom 51a, comprising a upper recess 71, a longitudinal groove 72 and a recess lower 73 that communicate with each other. The tube 62 comprises a leg bottom 75 in radial projection, which can be introduced and slide in one or the other of the recesses 71, 73 and in the groove longitudinal 72.

An upper ring 76, integral with fingers 57, and a lower ring 77, integral with the side wall of the element 52 by means of a curved arm 78 inserted in the slot 72, ensure the guidance of the tube 62 in translation.

One of the side plates 56 comprises a key retention plate 80 such as that, which allows the retention of a key 13 on the barrel 61. As it is more particularly visible in figures 4 and 5, this plate 80 it comprises a pin 81 that forms a pivot, which allows its pivoting in a horizontal plane, a pin 82 for mounting a end of a return spring 83 and a recess 84 similar to those described in reference to figures 1 and 2, while the stage 56 comprises a pin 85 for mounting the other end of the return spring 83, also similar to pin 28 described with reference to figures 1 and 2.

In figures 4 and 5 it can be seen that the plate it also has a vertical finger 90 on its opposite edge to the recess 84, located outside the inner perimeter of the wall circular 70 when plate 80 is in the inactive position (figure 4), and located inside this perimeter when said plate 80 It is in active position (figure 5).

When the pin 50 is in an access prohibition position, the leg 75 is inserted in the recess 71 and the key retention plate 80 is held in an inactive position by the return spring
lathe 83.

The introduction of the key 13 on the pivot 65, through a hole (not visible in the figures) made at the bottom 52a, and the pivoting of this key 13 allow to make pivot the barrel 61 and, therefore, drag the leg 75 out of the recess 71 and, simultaneously, by support of the pin 66 against pin 82, swing plate 80 in active position. Then, element 52 can be slipped into element 51, in against the elastic return force of the gas jack, until leg 75 is in front of recess 73.

Before the arrival of leg 75 to this position, finger 90 is introduced into the cavity delimited by the circular wall 70 and is leaning against the inner face of this wall 70, which allows the plate 80 to be held in the position of key retention 13 and makes the kite movement possible 61 and, therefore, of leg 75, regardless of the movement of this plate 80.

The key 13 can then be pivoted so take leg 75 to recess 73, as shown by the figure 5.

This key 13 is thus retained on the skipjack 61 through plate 80 as long as elements 51, 52 have not returned to the position that prevents access.

It is clear that the invention is not limited to the embodiments described above by way of examples but instead covers all its variants of realization. Thus, the blocking device to which it refers could not be a pivoting barrier or a retractable marker, but a tilting stand or, in general, any other device that prevents access to an area determined.

In addition, means may be provided for automatically carry the locking organ (finger 22 or leg 75) in locked position, when the device is in position that it allows access, such as, in particular, a spring.
