Definitions

  • the invention relates to an interlocking striker device for receiving a locking roller of a locking mechanism of the espagnolette or espagnolette lock type.
  • the present invention will find its application in the field of building hardware and relates, more particularly, locking fittings type espagnolette or espagnolette-lock equipped with locking members, type roller, roller or the like.
  • Striker devices for receiving a locking member in the form of a roller are common parts in the field of locking fittings type espagnolette or espagnolette-lock.
  • a strike device is generally intended to be fixed in woodwork rabbet, most often on the frame of a door, window or similar whose opening is equipped with the espagnolette or espagnolette-lock. It is in the form of a metal piece longer than wide, comprising, on one of its longitudinal edges, a cut forming an access ramp of a locking roller in a groove extending longitudinally on one side of said room.
  • the access of the roller to the striker through the aforementioned ramp is made in a direction perpendicular to the direction in which said groove extends.
  • the roller moves in this groove between a locked position and at least one unlocked position. In the latter, this roller is facing the ramp to allow it to be released from the strike and allow the opening of the door or window.
  • the document FR2 755 719 discloses a locking device for closing an opening by striking. However, this device does not provide any means of adjusting the roller, which has a significant drawback during assembly.
  • the document AT 365 718 discloses a roller with adjustment of the spacing with the frame, by a rotary oval roller.
  • the locking force is provided by friction of the rotation of the roller, and the durability of this effort is not guaranteed in time.
  • the present invention proposes to remedy at least some of the aforementioned drawbacks and proposes a solution that avoids having to manually actuate the locking fitting when closing the door, with a means of adjustment while proposing a force lock resistant perfectly guaranteed.
  • the invention relates to a one-piece locking roller of an opening on a frame, for example a window leaf on its frame, having a flat locking face intended to rest against a corresponding surface of the frame to lock the sash in the closed position, and an actuating face for moving a rod when closing the sash. It is particular in that it further comprises a flat compression locking face, intended to provide a second locking position so as to allow adjustment between two locking positions.
  • the locking face and the compression locking face are planar allows on the one hand a better contact resistance, the pressure on a flat surface being better distributed than on a circular roller, on the other hand guarantees the resistance to locking: indeed the roller can be mounted freely in rotation, in the locking position it is the locking force itself that prevents it from turning.
  • the invention also relates to a locking device, of type espagnolette or espagnolette lock, an opening on a frame, comprising a rod movable in translation, and a locking roller according to the invention attached to said rod.
  • This device is particular in that it comprises a return means of said rod, and in that said roller comprises a locking face intended to rest against a corresponding surface of the frame to lock the opening in the closed position, and an actuating face intended to move said rod during closing of the opening so as to allow its locking by said biasing means.
  • the advantage of the present invention is that it is sufficient to slam the opening, the roller according to the invention automatically actuates the fitting, so that it locks.
  • the plane locking face allows a more solid attachment to the striker, with guaranteed locking resistance effort.
  • the present invention relates to a roller 1, fixed free to rotate on a rod 2.
  • the roller 1 comprises a substantially cylindrical active portion 3, a washer 4, a square guide 5 and a head 6.
  • the square guide 5 is positioned in an opening 7 of a headrest 8, the width of the square guide corresponding substantially to the width of the opening 7 so as to lock the roller 1 in rotation (see Fig. 7 and 10 ).
  • the opening 7 has an elongated shape of constant width, except at its end, where it takes a circular shape with a diameter slightly greater than the diagonal of the square guide, to allow free rotation of the square guide for adjusting the roller in a different rotation position (see Fig. 8 and 9 ).
  • the head fixes the roller on the rod, and the washer 4 ensures a suitable sliding of the roller on the headrest.
  • the active part of the roller has a substantially cylindrical shape, whose section has, in the example shown in the form of a square with two rounded opposite angles.
  • the roller In the position of the Fig. 2 , the roller is in the position R-, with its locking face 9 on the right, about half of its height. This position is suitable for closing the leaf to the right.
  • This face is configured flat to improve the quality of the contact with the striker 11, and improve the strength of the lock, as well as the ease of sliding for engagement during locking and release when unlocking (see Fig. 6 ).
  • the rounded face 10 in the lower left corner constitutes the actuating face of the roller, which slides on an inclined surface 12 of the striker during the closing, and cause a movement of the rod 2 upwardly to reach the housing 13 lock latch 11 (see Fig. 5 and 6 ).
  • the roller In the position of the Fig. 3 , the roller is in the position L-, with its locking face 9 on the left, about half of its height. This position is suitable for closing the leaf to the left.
  • the rounded face in the lower right corner is the actuating face 10 of the roller.
  • the position of the roller at Fig. 4 is similar to that of the Fig. 3 , and is suitable for closing the leaf to the left.
  • the difference in positions of Fig. 3 and 4 comes from the fact that the axis of rotation of the roller is eccentric, so that the roller is positioned a little further to the right on the Fig. 4 in relation to its position of the Fig. 3 . Therefore, the leaf must go a little further before the roller can engage in the housing 13 of the striker 11. The leaf is therefore a little more pressed on the frame, and so we will call this locking face a compression lock face 14.
  • the actuating face of the Fig. 2 is the same curved face as the actuating face of the Fig. 4 , consisting of the rounded face at the bottom left of the Fig. 2 , this same rounded face being located at the bottom right on the Fig. 4 .
  • One face of the roller thus constitutes two actuating faces for two different situations.
  • the shape of the roller presented above allows the solution according to the invention to be implanted in standard fittings, with profiles or standard rebate machining for the opening, because the width of the active part of the roller can be identical to that of standard rollers, especially of circular shape.
  • the section of the active part of the roller 1 can take other forms, without departing from the scope of the present invention.
  • each of the two ends of each of the three faces of the triangle being able to constitute a locking face, simple or compressed or decompressed, and there we come to three possible setting positions as far right-fitting as left-mounted, which is an advantage for this embodiment.
  • the moment of inertia of the roller is substantially reduced, which limits its possible applications.
  • the shape of the inclined surface 12 must be specially adapted, and in particular have a lower angle of inclination, which reduces the possible locking height, unless the length of this inclined surface 12 is significantly increased, which means that can cause congestion problems.
  • the faces of the triangle can be bent until angles of 90 ° are obtained instead of 60 °.
  • the locking faces are no longer strictly plane but have such a radius of curvature that they can be likened to planar locking faces from the point of view of the distribution of forces on the face.
  • the radius of curvature obtained is of the order of 4 times greater than the radius of a circular roller of the same size, which allows to obtain the same advantages of distribution of forces as a plane locking face.
  • such a shape also makes it possible to guarantee the resistance to the locking force.
  • any rotation increases the pressure towards the frame. It is therefore also the locking force that prevents the rotation of the roller, which can be rotatably mounted.
  • the same effect is obtained as a plane locking face, making it possible to obtain the same guarantee on the resistance to the locking force.
  • the shape can also be that of a diamond.
  • Each of the faces of the rhombus is a locking face or a compression locking face, left or right.
  • the actuating face consists of the adjacent face of the locking face by the acute angle of the rhombus.
  • the angle of the diamond can be adapted to the shape of the striker, which represents an advantage over the triangular shape.
  • the moment of inertia is stronger than for the triangle, but less strong than the rounded square presented above. This moment of inertia can also be improved by rounding the obtuse angles of the triangle, which makes it possible to adapt to a standard strike with an acute angle of higher value.
  • This rounding can also be made so that the curvature reaches the acute angles.
  • the locking faces are also no longer strictly flat, but the radius of curvature is always at least twice greater than that of a circular roller of the same overall width, which removes most of the advantages correspondents.
  • Such a rounding may in particular be applied to a square shape, in which case the radius of curvature is substantially equal to twice the radius of the circular roller of the same overall width.
  • the resistance to the locking force is also guaranteed with a mounting of the free roller in rotation, for the same reasons as for the triangle above.
  • the keeper 11 is fixed to an amount of a frame, the rod being fixed to the opening in the plane perpendicular to the opening, the roller extending protrusion in the plane of the opening.
  • the rod is connected to a handle or a lock constituting a espagnolette or espagnolette lock, fixed rabbet on the opening.
  • the advantage of the present invention lies in particular in that the opening can be slammed or closed by simply pushing the opening on the frame without requiring action on the handle.
  • the flat shape, or large curvature, of the locking face facilitates its sliding in the housing of the striker, and thus facilitates its engagement and unlocking, while ensuring a greater locking force.
