Description

"Security arrangement with an access gate,

  The present invention relates to a safety arrangement for a door or a gate equipping for example a barrier 5 for protecting the access to a pool, in particular the pool of a pool.

  The invention is also applicable in all cases where it is necessary to provide security means to prevent the manipulation of the door, that is to say the door or gate, to a child in such as a child under five years old. This is for example still the case of a gate prohibiting access to a staircase arranged inside residential premises.

  With regard to protected access to pools, the concerns of protecting young children in order to prevent their accidental drowning in the event of lack of supervision, led to the publication of recommendations and standards for prevent the risk of unlocking by young children or an unwanted unlocking.

  For this purpose, the system where the unlocking means must require at least two consecutive actions on the unlocking system to release it, the second action being dependent on the first which is carried out previously and maintained, or require two separate but simultaneous actions acting according to different principles, or to include two unlocking devices at least one meter distant and to be operated simultaneously.

  The means or the locking mechanism of the opening, must also allow automatic locking when the door closes itself or is closed by a user.

  For this purpose, it has already been proposed in US-A-5.217.265, a security arrangement of the type comprising: - a fixed frame comprising a first vertical upright and a second vertical upright defining between them a passage; - An opening, in particular a door or a gate, which is pivotally mounted relative to the first upright, between a closed position in which it extends vertically between the two uprights to close the passage, and an open position - a mechanism, the type thresher, locking the sash in the closed position, which comprises: a strike fixed on the second upright and open upwards; and a manually operated bolt which is pivotally mounted on the sash, about a horizontal axis, between a retracted high position in which the bolt is disengaged from the striker to allow opening of the sash, and a position low locking to which the bolt is recalled and in which it is engaged in the strike; and safety means controlled manually and independently of the bolt of the thresher to prevent the control of the tilting of the bolt from its low position to its upper position when the sash is in the closed position.

  In this document, the manually and independently controlled safety means of the threshing machine are of complex design with a lever motion transfer system.

  These complex means significantly increase the cost of the security means and also have significant risks of jamming, especially because of corrosion when such an arrangement is used in a humid environment, these risks being increased because of the particular forms of components that cooperate to prevent the control of the tilting of the bolt.

  The invention aims to provide an arrangement of the type mentioned above that overcomes these drawbacks, which is simple in design and whose production and maintenance costs are particularly low.

  For this purpose, the invention proposes an arrangement characterized in that the safety means comprise: a plate comprising a locking hole which is arranged on the second upright, or on the bolt; - And a locking pin which is movably mounted relative to the second post, or relative to the bolt respectively, between a locking position of the bolt in the low position towards which the locking pin is permanently recalled and in which a section of The free end of the blocking finger is received in the blocking hole, and an erased release position in which the free end section of the blocking finger is out of the blocking hole.

  According to other features of the invention: the locking pin is slidably movable in a horizontal direction parallel to the plane of the opening when the latter is in the closed position; - The locking finger is elastically biased towards its locking position of the bolt; the bolt of the threshing machine is gravity biased back to its low lock position; the bolt is elastically biased towards its low locking position; the arrangement comprises stop means which determine the low locking position of the bolt; - The striker includes a ramp which cooperates with a portion of the bolt to cause the automatic retraction of the bolt during closing of the opening; the arrangement comprises means for causing the automatic erasure of the blocking finger during the closure of the opening leaf. The means for causing the automatic erasure of the blocking finger include an erase ramp formed on the section of the opening. free end of the locking finger, or on the plate, which cooperates with an edge of the plate, or with the free end section of the locking finger respectively, when closing the sash - the arrangement comprises stop means for determining the closed position of the opening relative to the second amount and the opening direction of the opening.

  Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which: FIG. 1 is a schematic perspective view illustrating a pool of swimming pool around which is arranged a fence equipped with an access gate which constitutes a safety arrangement according to the teachings of the invention and on which the gate is in the closed position; - Figure 2 is an enlarged detail view of the upper part of the gate with its lock thresher in the locking position in association with the adjacent vertical amount of the fence; FIG. 3 is front detail front view of FIG. 2; Figure 4 is a top view of Figure 4; and FIG. 5 is a longitudinal end view along the arrow F5 of FIG. 3.

  In the following description, like, like or like components and elements will be referred to by the same references.

  In order to facilitate the understanding of the description and of the claims, the terms front, rear, left, right, vertical, longitudinal and transverse, in particular with reference to the trihedron V, L, T indicated in the figures, will be adopted without limitation.

  FIG. 1 shows part of a fence 10 surrounding a pool 12 of a swimming pool. In a known manner, the fence 10 consists of a series of posts or uprights 14 distributed regularly, and a series of panels 16 each of which extends longitudinally in a vertical plane between two consecutive posts 14.

  In order to allow access to the basin 12, there is provided a door or gate 18 which is arranged between a first post or left post 14G and a second post or right post 14D. the two posts 14G and 14D delimit between them the access passage to the basin when the gate is open.

  The gate 18 is pivotally mounted about a vertical axis XX substantially corresponding to the axis of the left vertical pole 14G is arranged in the vicinity of the left vertical edge 20 of the gate 18 whose vertical right edge 22 is adjacent to the vertical edge left free 24 14D right post, when the gate 18 is in its closed position illustrated in Figures 1 and 2 wherein it extends longitudinally in the vertical plane common to the two posts 14G and 14D which frame.

  The constituent panel of the gate 18 is also delimited by an upper horizontal edge 26 whose altitude is substantially equal to that of the handrail 28 which extends to the upper part of the fixed panels 16.

  The mechanism 30 for locking the gate 18 in the closed position is a threshing machine which comprises a manually operated pivoting bolt 32 which cooperates with a complementary keeper 40.

  The bolt 32 is in the form of a lever which is pivotally mounted on the upper part of the gate 18 near its horizontal upper edge 26 and its vertical right edge 22, that is to say generally in the upper right corner of the door 18.

  The bolt 32 is in the form of a vertical plate 30 adjacent to the front or outer face 17 of the gate 18.

  The left longitudinal end 34 of the bolt 32 is articulated on the gate 18 around a horizontal axis Y-Y which constitutes the axis of tilting of the bolt 32 with respect to the gate 18.

  The plate constituting the bolt 32 is delimited vertically downwards by a curved longitudinal edge 36 which comprises a right end section 38 which constitutes the actual functional part of the bolt 32 which, in the closed position of the door 18, is received in the additional keeper 40 of the mechanism 30.

  The striker 40 is a fixed element carried by the straight pole 14D.

  The striker 40 has a vertical plate 42 which extends in a vertical plane and transverse and forward, that is to say outwardly. The plate 42 is fixed, for example by welding if the various components are metallic or by any other means adapted for this purpose, on the front or outer face 15D of the right-hand post 14D, in the vicinity of its left-hand vertical edge 24 and its horizontal upper edge 44.

  The plate 42 is delimited by a rear vertical edge 46 adjacent to the face 15D and which has at its upper part a cutout to delimit with the face 15D a vertical slot 48 which constitutes the keeper itself, which is open vertically upwards and in which is received the portion 38 of the lower edge 36 of the bolt 32 when the locking mechanism 30 is in the locking position illustrated in particular in Figure 2.

  To manually control the tilting of the bolt 32 about its axis YY, it comprises at its upper part and in the vicinity of its longitudinal end of the right opposite its axis of tilting Y-Y, two opposite horizontal handles before 50 and rear 51.

  From the low locking position of the bolt 32 shown in Figure 2, the handles 50 and 51 can lift the bolt 32 to clear the section 38 out of the slot 48 and allow the opening of the gate to the front , ie to the outside, by pivoting about its vertical axis XX.

  The tilting in the direction of the opening or unlocking of the bolt 32 towards its retracted high position 5 takes place against the mass of the bolt 32.

  The angular deflections in both directions of the bolt 32 around its tilting axis are delimited here by two horizontal pins 52 and high fixed low stops 54 which are carried by the front face 17 of the gate 18.

  The position of the high stop pin 54 is such that, if the user releases the bolt 32 in its high position in which it is in abutment against the high stop pin 54 by a portion vis-à-vis its edge longitudinal upper 37, the bolt 32 falls by gravity, that is to say automatically switches to its low locking position and to a maximum position to which, when the gate 18 is open, it is supported by the portion in vis-à-vis its lower edge 36 on the fixed lower stop pin 52.

  As a variant not shown, the two pins 52 and 54 can be replaced by a single horizontal pin which extends inside a circular arcuate hole formed in the plate of the bolt 30 and which cooperates with the one or other of the two ends of the light to define the two high and low positions.

  According to a variant not shown, the gravity return of the bolt 32 of the thresher 30 to its lower position can be completed by elastic return means.

  The arrangement of the bolt 32 with its operating handles 50 and 51 in the upper part of the gate makes it already very difficult to handle a small child.

  The plate 42 of the striker 40 is delimited by a convex curved upper edge 56 which constitutes a ramp or a cam profile which cooperates with the portion opposite the section 38 of the lower edge 36 of the bolt 32 when one closes the gate 18 and the bolt 32 is in the low position resting on the fixed fixed stop pin 52.

  Thus, it is possible to obtain closure and automatic locking of the thresher 30 because the ramp 56 causes the progressive lifting of the bolt 32, that is to say its tilting in the counterclockwise direction by considering FIG. section 38 is opposite the slot 48 and enters automatically by gravity.

  The closed position of the gate 18 in which it extends longitudinally between the two posts 14D and 14G, is determined by a vertical stop tab 60 carried by the right-hand post 14D near its upper end and against which the gate 18 comes supported by the portion vis-à-vis its vertical rear or inner side 19, with the interposition of a damping block 61.

  The tab 60, in addition to its function of determining the closed position of the gate 18 to ensure alignment in the same vertical plane of the bolt 32 and the slot 48, also provides a function of prohibiting the opening of the gate 18 to the rear, or interior, according to certain regulatory or normative aspects mentioned above.

  In order to ensure child safety, means 62 are provided that are manually and independently controlled by the bolt 32 of the thresher 30 to prevent the bolt 32 from being manipulated for the purpose of unlocking and opening the door 18.

  According to the teachings of the invention, these means 62 comprise a locking pin 64 and a locking plate 66.

  In the embodiment shown in the figures, the locking plate 66 is a vertical plate which is made integrally in one piece with the bolt 32, for example sheet cut and folded.

  The plate 66 extends vertically in a plane perpendicular to the general plane of the plate constituting the bolt 32 and rearward, that is to say inwards.

  In the closed position of the gate 18 and locked the thresher 30, as can be seen in the figures, the locking plate 66 thus extends, from the vertical end right edge 69 of the bolt 32, in a vertical transverse plane. As can be seen in FIG. 4, the locking plate 66 extends transversely over the entire width of the right-hand post 14D, and it comprises a central locking hole 68 which is a horizontal hole opening into the position illustrated in FIGS. FIGS.

  The locking pin 64 is a movable finger guided in sliding along a horizontal and longitudinal axis Z-Z and which is manually controlled by a control handle 70 fixed to one of the longitudinal ends, right of the finger 64.

  The finger 68 extends horizontally in a longitudinal vertical plane and is slidably guided in a guide tube 72 which is itself fixed by welding on a support plate 74 carried by the right post 14D.

  The support plate 74 extends in a transverse vertical plane above the upper face 44 of the pole and, in the position illustrated in the figures, it is adjacent to the locking plate 66 carried by the bolt 32.

  More specifically, and as can be seen in FIGS. 3 and 4, there is a slight clearance in the longitudinal direction between the left vertical and transverse face 75 of the support plate 74 and the vertical and transverse face of the right-hand side. -vis 67 of the locking plate 66.

  The support plate 74 comprises a hole 78 for the passage of the left free end section 80 so that it can penetrate longitudinally inside the blocking hole 68 which, when the bolt 32 and in its lower position illustrated in FIGS. Figures that and the gate 18 is closed, is in coincidence with the hole 78 and so that the blocking finger 64-80 can enter.

  The blocking finger 64 is resiliently urged permanently towards its so-called locking position in which its left free end section 80 projects axially through the hole 78 beyond the left face 75 of the support plate 74. in particular to be received in the locking hole 68 when the gate 18 is closed.

  The elastic return means are not shown in detail in the figures but simply in the schematic form of a return spring 82.

  A traction action on the control handle 70, from the left to the right considering for example Figure 3 and as shown in the figures, is exerted against the elastic return force of the spring 82 to obtain a deletion of the finger 64, that is to say to cause the axial withdrawal of its left free end section 80 recessed to the right beyond the face 75.

  In the locked position illustrated in the figures, the section 80 is received in the hole 68 and it is therefore impossible for a user to cause the bolt 32 of the thresher 30 to tilt, in the counter-clockwise direction, in order to unlock the gate 18.

  The opening of the gate 18 therefore requires first of all to act manually by pulling on the handle 70 to release the safety means, then maintaining with a first hand the pulling force of release on the handle 70, then act with his other hand on one or other of the two handles 50, 51 to unlock the bolt 32 of the thresher 30 by tilting as indicated by the corresponding arrow in the figures.

  The user can then release the handle 70 of the security means and then open the gate 18.

  Due to the arrangement of the handle 70 for maneuvering the security means 62 in the upper part of the post 14D, it is impossible for a small toddler, and particularly a child under five, to act on the handle 70 and thus open the gate 18.

  This provides, with simple and reliable means, absolute security.

  When a user closes the gate 18, the rear transverse vertical edge 84 of the locking plate 66 comes into contact with the left free end section 80 of the locking pin 68, possibly preventing the gate from closing completely. 18 and its locking by the thresher 30 without voluntary manual action on the handle 70.

  In order to obtain an automatic closing of the gate 18 with its locking by the thresher 30, it is for example possible to conform the free end section 80 in a point or with a ball (according to details of embodiment not shown in the figures) to obtain a ramp or cam effect in cooperation with the edge 84 which causes the automatic erasure of the blocking finger 64, 80 when the gate 18 is closed.

  If the height of the locking plate 66 is small enough that, because of the action of the upper edge 56 of the striker 40, the lower horizontal edge 65 "passes" above the section 80 when closing the gate 18, the ramping effect for the automatic erasure of the blocking finger 64 then occurs during the fallout of the bolt 32 by gravity for the purpose of locking and by cooperation of the lower edge 65 with the free end pointed or shaped lock ball ball 64, 80.

  In all cases, therefore, a closure is obtained and then an "automatic" locking and locking.

  Alternatively, instead of conforming the tip portion 80, it is also possible to chamfer the edges 84 and 65 which then act in turn as a ramp or cam to cause the automatic clearing of the locking pin 64 when the closing of the gate 18.

  According to a variant not shown, it is also possible to provide that the locking pin 64 with its guide and control means are carried by the bolt 32 of the thresher 30, while the associated locking plate is then a fixed platen worn from the top of the right 14D pole.

  The invention is not limited to the embodiment which has just been described.

  The bolt of the threshing machine can be double with a U-section to overlap the upper edge of the gate.

  Depending on the application, the gate can open in both directions and the thresher then determines the closed position of the gate in which the latter is aligned with the two amounts that surround it. A cam lock is then provided on each side of the corresponding amount.

  The uprights are not necessarily posts, but can also be amounts belonging to any frame such as a door frame in a wall.

  It is also possible to provide indications to suggest to a user the sequence of manipulation of the handles to open the gate and indications by arrows on the direction of the various maneuvers.

  For example, it is possible to provide different colors for the handles.

  The various handles are not necessarily in the form of balls and the handles 50 and 51 can for example be integrated into the bolt proper.
