Description

i

  The present invention relates to an oleopneutical safety device

  locking mechanism for the condemnation of openings of all kinds

  and in particular door-gate safety doors by way of

diary of a liquid under pressure.

  In the known technique to date, the majority of automatic door opening systems are controlled by electric motors,

  which does not always give complete satisfaction.

  As well,. the present invention, using the force produced by the movement of the leaf to actuate the bolt, is intended to remedy

  to these disadvantages and will be better understood by reading the description

  hereinafter made with reference to the accompanying drawings, in which:

  FIG. 1 represents a door block equipped with the oleopneumatic device

lock.

  FIG. 2 represents the operating diagram of the invention

and its different organs.

  FIG. 3 shows the different positions of the valve of

  command: A - closed position, B - open position and C - locked position.

  FIG. 4 represents the master cylinder according to the invention,

  both the addition of a braking system.

  FIG. 5 shows the "U" shaped bolt used for the application of

  application of the invention to a tempered glass door (Securit or other type).

  Figure 6 shows a bar-shaped bolt.

  FIG. 7 represents a battery of pistons with shaped bolts

  advanced for accordion, slide or rocker doors.

  Figure 8 shows the adaptation of the entire device

  Oleopneumatic locking according to the invention, on an existing door.

  The oleopneumatic locking device comprises in particular a blockporte (50) whose leaf (1) pivots on an axis (2) provided with a pinion (3) which drives a rack (4). Said rack (4) actuates a

  piston (5) with check valve (6) sliding in a cylinder (7) encas-

  tré in the low crossbar (8) of the frame (26).

  The cylinder (7) is connected via the pipe (9) to the supply tank (10) of the liquid (11) and via the pipe (12) provided with a check valve (13) to the tank (14) containing liquid (11) and

  the air (15). The tanks (10) and (14) are interconnected by a channel

  sation (16) provided with an adjustable safety valve (17).

  The tank (14) is connected to the different lock cylinders

  ge (18) through the lines (19) and (20) when the control valve

(21) is in position A (closed).

2 2613752

  The locking cylinder (18) is provided with a piston (22) making.

  bolt function (piston-pin) and a return spring (23). The pistonpeno

  (22) engages in the striker (24) fixed on the wing (1).

  The valve (21) in position B, connects the piston-bolt (22) to the tank (10) via the pipes (20) and (25). The pipes (9) (12) (19) (20) and (25) flexible or rigid, may have a variable length depending on the implantation of the

  valve (21) and locking cylinder (18).

  The tanks (10) and (14) can be fixed horizontally or vertically in the frame (26) of the door block (50) or in any other

position of the partition (27).

  The locking cylinder or cylinders (18) can be in number

  variable and positioned on either side of the frame (26).

  The control valve (21) acting as a latch has three channels which allow the ducts (19) and (20) for closure (position A) or the ducts (20) and (25) to be joined together. for opening (position B). In position C the pipes (19) (20) and

  (25) are obstructed, the valve is in the locked position.

  The present invention can serve as a door brake, in this case the

  the master cylinder (40) further comprises sprinklers (28) of different cali-

  and a spring (29) for braking both opening and closing. For the condemnation of tempered glass type or other types of doors, the bolt piston (22) will have the shape of a "U" which blocks the door (1) in the closed position. For opening, the piston-bolt (22) shaped "U" retracts and releases the door (1). It can be mounted alone or in battery,

  on the bottom rail (8) of the frame (26) or in the ground.

  The bolt may be in the form of a bar (30) held by the pistons (22); the bar (30) of appropriate dimensions is housed in the leaf

  (1) in the closed position and locks it.

  The bolt pistons (22) will be peak-shaped and arranged in battery for the condemnation of rocking doors, accordion, sliding or other. They then enter the band of strikes (24) fixed on the

moving parts of said doors.

  For its application to the existing doors, the device oleopneu-

  the locking mechanism will be fixed on the upper crossmember (31) of the frame (26), the circular movement of the door (a) will then be transmitted to the piston (5)

  using a compass (32) which transforms it into rectilinear motion.

  In all the embodiments of the invention, the control of the valve (21) (mechanical, electrical, electronic or other) can be

done near or at a distance.

  The mechanism and the pipes can be embedded in the frame (26) or the partition (27) or arranged in applied and covered with covers. When opening, the rotation movement of the leaf (1) of the

  door block (50) in its hinge axis (2) is converted into linear motion.

  re either by a gear rack (3) and (4), or by a cam, a

  lever, a compass, bièles-or others.

  This movement controls a piston (5) sliding in a cylinder (7). The check valve (6) then being closed by the pressure of the liquid

  (11), the piston (5) sucks the liquid (11) from the reservoir (9) through the pipe (9).

  see supply (10) and discharges through the pipe (12) the liquid (11) to the reservoir (14). the air (15) contained in this reservoir (14) is

  then compressed. the check valve (13) prevents the return of the liquid (11).

  When closing the door (1) the check valve (6) of the piston

  (5) is then released and the piston (5) flows freely in the cylinder (7).

  To lock the door, place the valve (21) in the position A. under the effect of the pressure of the reservoir (14) the pipes (19) and

  (20) flow the liquid (11) to the one or more locking cylinders (18).

  The liquid (11) actuates the piston-bolts (22) provided with a return spring

(23) that is compressed ..

  When the piston-bolt (22) is under pressure, latch engaged in the striker (24), spring (23) compressed, the locking is performed and the door

(1) sentenced.

  the compression due to the movement of the piston-bolt (22) during the

  closing, is absorbed by the air (15) of the reservoir (14).

  To open the door (1) simply actuate the valve (21) and put it in the open position B. The piston-bolt (22) under the action of the return spring (23) forces the liquid into the pipes (20) and (25). It returns to the filling tank (10), the striker (24) is released and the door (1)

can open.

  In blocking position C, the valve (21) obstructs all circuits

  to give any guarantees in case of prolonged closure.

  If the pressure becomes too great in the tank (14), which would cause the blocking of the door (1), an adjustable safety valve (17) allows the liquid (11) of the tank (14) to flow into the tank

see power supply (10).

  When the master cylinder (40) is equipped with the braking system: On opening: the suction by the piston (5) of the liquid (11) from the filling tank (10) is via sprinklers of

  various gauges (28) which slow down the arrival of the liquid (11).

  At closing: the spring (29) compressed during opening, relaxes in

  pushing the piston (5) into the rest position.

  The device according to the invention does not require any energy input

  other than that produced by the movement of the door. It removes the engenders

  swims and joints of the mechanisms that are found in existing locks. It offers a great flexibility of installation compared to

fixed locks.

  Depending on the forms of bolts used, it becomes possible to apply

  this device to all types of doors with a circular movement

  opening, particularly at entrance and landing doors, armored, shutters, tempered glass door type or other type, rocking doors,

  accordion, industrial doors, grilles or others.

  The installation can comprise as many strikes (24) and bolts (22) as one wants according to the desired resistance, which can be

  possibly arranged on the entire periphery of the door.
