Description

The present invention relates to handle mechanisms for doors and

  similar closure members, of the kind in which a handle is rotatably mounted on a fixing plate and is capable of alternately and alternately occupying at least one of

  two angular positions relative to this plate.

  A handle mechanism of the kind described may

  be used for example to maneuver a system of ver-

  multi-point rusting, i.e. a system in which two or more locks are mounted on a door or the like, and are arranged to be actuated by a common handle. For example, a lock may be mounted on the door at the usual location, in the middle or about the opening side edge of this door, opposite the hinges, and other latches may be mounted substantially at the opposite ends of said door, or in that opening side sill , either in the edges of these ends, and all these locks can be manipulated by a single handle, conveniently adjacent to the first latch mentioned in

  these arrangements, it is usual for the handle to occupy alternately

  one of the two locks, a first one when only one of the locks is closed, and from which it is possible to turn it to release this lock, and another when all the locks must be The action of the springs of the locking mechanisms is used up to now to maintain the handle in one and

the other of his positions.

  The present invention relates to a handle mechanism for a door or similar closure element, which comprises a handle rotatably mounted on a fixing plate and able to occupy in turn and alternately at least two angular positions relative to this plate, a rotatable member disposed in said plate, rotatable with this handle and having

  minus two abutment surfaces which have angular orientations

  different from the axis of rotation of the handle, the angle made by these corresponding abutment surfaces

  at the angle between the alternating

  of this handle, and a cooperating position member

  or holding, also arranged in the fixing plate, biased by springs towards this rotary member and intended to come into contact with one or the other of the abutment surfaces, according to that of the angular positions which is occupied by the handle, so as to keep it in position

respective angle.

  A multi-point locking system in which two or more locks are mounted on a door or similar closure member may be arranged to be actuated by a handle mechanism such as that defined in the preceding paragraph, this handle can be rotated in one direction, from one of its angular positions in which only one of the latches is in the projecting closing position, to an angular position

  alternative in which all locks occupy their posi-

  protruding lock, be turned in the opposite direction from the first angular position, so as to back the first latch of its locking position.

  It can be seen that the handle mechanism according to the invention

  tion has its own spring or springs to hold the handle in one or other of its positions, and therefore it has not to resort to the springs locking mechanisms with which it cooperates in service, for keep this handle in its positions, as it is the

  case with known mechanisms of the kind described.

  The handle, which in most cases will conveniently be a cane, can be arranged to occupy alternately more than two positions. Regardless of the number of positions that this handle can occupy, the rotary member has a corresponding number of stop surfaces

  having corresponding angular orientations.

  The direction of the handle's orientation can

  it can easily be reversed without having to remove it from the fixing plate, or to remove or reposition any other element of the mechanism to perform this reversal of direction. It is possible to simply turn this handle of 1800 to make it happen

  from one side to the other so that the handle is easily reversed

  it is appropriate for the rotary member to have abutment surfaces with which the holding member can cooperate,

  whatever the direction in which this handle is placed.

  The rotatable member may be a wafer and

  wear the abutment surfaces, appropriately

  lines, formed on its periphery It can be attached to the

  handle or rod-that handle turns.

  The holding member may be a sliding solid piece or a similar element having an abutment face intended to cooperate with the abutment surfaces. One or more compression coil springs may act

  on this member so as to push it towards the rotary member.

  There can be only one handle, if for example the mechanism is intended to be mounted on a door that must be operated by one-sided handle This

  door can be operated on the other side by means of a key.

  But a mechanism according to the invention may comprise two handles, mounted on both sides of the door on which this mechanism is mounted In such an arrangement, the rotary member can rotate with the two handles, because it is usually secured to a common maneuvering rod

  locks, arranged between these two handles.

  The invention will be described in more detail by way of non-limiting example, with reference to the accompanying drawings, in which: Figure 1 is a partial view from the rear of a handle mechanism according to the invention; and FIG. 2 is a perspective view of a

  door equipped with a locking system in several points.

  The handle mechanism shown in Figure 1 is intended to be mounted on a door and comprises a cane 1, which is pivotable on a fixing plate 2, in which are housed a rotatable member 3 and an organ

  hold 4 biased by springs.

  The fixing plate 2 comprises a U-shaped shaped oblong body, closed at its opposite ends by recessed elements 6, only one of which is shown and which are pierced with screw holes 7 for fixing this plate to the door. Said fixing plate is usually mounted so that its large dimension is oriented vertically, as shown in FIG.

  lateral wings 8 of the U-shaped body 5 are folded towards the inside.

  A keyhole is formed in the anterior wall 10 of the body 5 when the handle mechanism is intended to be formed.

used with a lock.

  The spout 1 has a tail, not shown

  felt, journalled in a known manner in a hole in the anterior wall 10 of the body 5 of the fixing plate, so as to be rotatable relative to this plate The rod 11, to

  square cross-section of a locking mechanism, not shown

  felt, passes into a complementary socket of this tail,

  so as to turn with the beak.

  The rotary member 3, which is constituted by a rectangular plate, is wedged in the middle on the rod 11, so as to rotate with it and thus with the beak

  The length of the long sides of this organ is suf-

  considerably lower than the distance between the lateral wings 8 of the body of the fixing plate so that said

  organ can turn 180 without coming to touch these wings.

  The sides of the rectangular rotary member serve as surfaces

  stop 12, 12 'and 12 ", as will be described later.

  The holding member 4 is slidably mounted in the body of the fixing plate above the rotary member 3 in FIG. 1. This member has the shape of an oblong plate and has on its opposite sides two recesses 13 starting at The organ therefore has the general shape of an inverted T The transverse bar 14 of this T has the desired width to fit slidably between the wings 8 of the body of the body. the fixing plate, and it is partially covered

  of the transverse bar 14-of said holding member.

  Although the member has been described and shown as being above the rotary member, it can be mounted in the fixing plate below this rotary member,

  if it is desirable or necessary.

locks 18, 19.

  To close only the latch 18, it is pos-

  It is possible without disadvantage to occupy at the can beak 1 of the handle mechanism the horizontal position shown in FIG. 2 and in full lines in FIG. 1. In this position, one of the large abutment surfaces 12 of the rotary member is in position. contact with the lower face 15 of the holding member, and the elastic thrust applied to the latter positively maintains the cane in this position. When this cane occupies this position, the latch 18 is normally in its projecting position. This lock 18 can be retracted by rotating the cane downwards. The springs 16 allow the holding member to deviate sufficiently from the rotary member to allow this rotational movement of the spout. The locking mechanism normally prevents this spout from rotating beyond an angle beyond

  which springs could not make autofa- return.

  In a variant, it is possible to arrange in the fixing plate 2 one or more stops intended to limit the amplitude of the pivoting of the cane towards the

  down, so as to ensure that it can not be brought to a

  tion in which an edge or other side of the rotatable member could come into contact with the underside of the transverse bar 14 of the holding member,

  preventing this beak from automatically returning to the position

horizontally.

  To close simultaneously all the locks 18, 19, the cane or other handle can be brought

  at an angular position in which it is vertically oriented

  upwards, as shown in phantom in 1 '

  springs on this holding member.

  If the direction of orientation of the spout must be changed, it is possible to rotate the spout of 1800, from one of its horizontal positions to the other, as indicated in 1 "in Figure 1 , so that it is the large abutment surface 12 ", opposite the rotary member, which is in contact with the holding member when the cane beak occupies this other horizontal position It is still possible to rotate this beak duck down, for

  It is of course possible to arrange the mechanism

  a rotary member, (the form other than rectangular.

  As shown in the embodiment described, the invention makes it possible to obtain a handle mechanism

  relatively simple and cheap conformation, which

  positively holds the handle by applying the action of springs in the active positions to which it can be

brought into service.

  It goes without saying that it is possible, without departing from the scope of the invention, to make various modifications

  to the handle mechanism described and shown.
