Definitions

• the present invention relates to a keeper of the type intended to equip the door leaf with a door in particular, an elevator landing door.
• Such a strike is intended to cooperate in closing with a lock bolt, said strike being disposed opposite the bolt in the frame of said door, in order to allow the latter to be introduced therein.
• Said keeper is introduced into the rebate of the door and is fixed thereon on an internal field of the latter by means of fixing screws situated on either side of the bolt hole, of diameter substantially greater than the external diameter of the strike cylinder.
• the difficulty lies in the non-accessibility of the internal housing of the door leaf.
• the positioning is therefore carried out by sliding this traditional keeper from the top of the leaf until bringing its fixing holes opposite two corresponding holes in the leaf. The operator must then use the other hand to tighten two fixing screws.
• the object of the present invention is to remedy this drawback by proposing a keeper which is mounted in place of a traditional keeper by acting on the leaf in an entirely external manner. Therefore, no opening should be made in the leaf and in addition, the intervention will be quick and not tedious for the operator.
• the invention relates to a keeper of the type intended to equip the leaf of a door in particular a landing door of an elevator and to cooperate in closing with the bolt of a lock arranged opposite a frame of said door, said strike being introduced into the rebate of the leaf and fixed on a field thereof, by means of fixing screws passing through holes located on either side of a passage hole of the bolt of substantially diameter greater than the outside diameter of a strike cylinder, characterized in that the strike consists of:
• a strike cylinder intended to be attached to the bottom of the element, the bottom of said cylinder also being pierced with a smooth hole coming opposite that of the bottom of the element with which said cylinder will be secured;
• a central rod the lower end of which is threaded from a stop and intended to pass through the smooth hole in the bottom of the strike cylinder and to be screwed into the nut freely caged on the bottom of the support element, said rod thus also constituting a connecting element of different constituent parts of the keeper.
• the present invention also relates to the characteristics which will emerge during the description which follows and which should be considered in isolation or according to all their possible technical combinations.
• FIG. 1 is an exploded perspective view showing the mounting of a traditional keeper in a leaf ;
• FIG. 2 is a perspective view of a leaf provided with a keeper according to the invention, shown opposite a traditional frame provided with a lock carrying a locking bolt;
• FIG. 3 is an exploded perspective view of a keeper according to the invention during assembly in the rebate of a leaf;
• - Figure 4 is a schematic view showing the different stages of mounting the keeper according to the invention, in the rebate of a leaf.
• the strike 1 is of the type intended to equip the leaf 2, for example of a landing door of an elevator, and to cooperate in closing with a bolt 3 of a lock 4 arranged opposite in a frame 5 of said door with a rod 6 arranged coaxially in a strike cylinder 7 corresponding to the bolt 3 intended to be introduced therein, said strike 1 being introduced into the rebate 8 of leaf 2 and fixed on a field 9 thereof, by means of two fixing screws 10 and 11 passing through two holes 12 and 13 located on either side of a passage hole 25 of the bolt 3 of diameter substantially greater than the external diameter of cylinder 7 of keeper 1.
• the keeper 1 consists of:
• a support element 14 generally in the form of an omega with straight sides and substantially perpendicular to one another, two lateral end wings 15 and 16 of which are pierced with holes and equipped with threads 17, 18 at a center distance corresponding to that of the fixing holes 12 and 13 produced on the leaf 2 and the bottom of which, consisting of a vertical branch 19 connecting two horizontal branches 20, 21, is also pierced with a hole 31 fitted with a nut 22 engaged on the bottom 19, the width " 1 "of said support element 14 being less than the diameter D of the bolt hole 25 of the leaf 2;
• a strike cylinder 7 1 intended to be attached to the vertical branch 19 of the support element 14 and whose bottom 26 is also pierced with a smooth hole 27 coming opposite that 22 of the vertical branch 19 with which said cylinder 7 will be joined;
• a central rod 6 a lower end 28 of which is threaded from a stop 29 and intended to pass through the smooth hole 27 in the bottom 26 of the keeper cylinder 7 and to be screwed into the nut 22 freely engaged on the bottom 19 of the support element 14, said central rod 6 thus also constituting a connecting element of different constituent parts of the keeper 1.
• the threaded holes 17 and 18 of the lateral wings 15 and 16 are constituted by caged nuts added in oblong slots of said wings 15 and 16 so as to adapt to the distance between the fixing holes 12 and 13 correspondents of leaf 2.
• the threaded hole 31 of the bottom 19 of the support element 14 is equipped with a caged nut 22 attached in the hole 31 which is constituted by an oblong slot, so as to be struggled with it freely in a longitudinal direction at the time of assembly, then to authorize a centering of the cylinder 7 of striker 1 and of the rod 6 which is screwed thereon and consequently of the cylinder 7 of striker 1 relative to the bolt 3 with which it is susceptible to cooperate.
• the oblong opening 31 of the bottom 19 of the support member 14 is a circular hole extending radially in a longitudinal direction by a straight extension, in the manner of a buttonhole.
• the keeper can undergo a depth adjustment in the leaf, obtained by the insertion of wedging washers 40 between the bottom
• the invention also relates to the method of mounting the keeper 1 described above.
• the support element 14 in the form of an omega; . the strike cylinder 7;
