Definitions

• the invention relates to a device for motorised opening and closing of folding doors, panel doors, folding gates, and panel gates, in the following referred to as doors, wherein the door is opened and closed by means of a motor drive transmission acting on the door and which, independent ofthe direction of movement ofthe door, will disengage the door, so that the door is released and will stop in case of an obstacle, independent of a continued motor motion.
• Torverk's link arm release Swedish patent No. 8100121-6.
• Fig. 1 is a longitudinal section through a safety release mechanism
• Fig. 2 is a view from above
• Fig. 3 is view from below, wherein the safety release mechanism in its released state is indicated
• Fig. 4 schematically shows the device in its functional environment.
• the integrated equipment in which a safety release mechanism is included as a part thereo ⁇ consists ofthe following main parts, namely a power transmission member 1, a disengagable lever 2, a disconnection unit 3, a moment lever 4, a first pull-push link 5, a second pull-push link 6, a power transmission release coupling 7, and a member 8 here referred to as latch lock member.
• the safety release mechanism which in Fig. 4 schematically is represented by the unit 10, consists ofthe power transmission member 1, the disengagable lever 2, the disconnection unit 3, the moment lever 4, the power transmission release coupling 7, the latch lock member 8.
• a motor mechanism for driving the device is assembled in a motor mechanism box 9 above the device (only partly shown).
• the power transmission member 1 consists of a cylindrical part 11 and a straight lever 15 projecting at a right angle from the said cylindrical part 11. Under one end of lever 15 there is a flange member 16 with an inwardly turned rim 17, the upper surface of which having bevelled edges.
• the cylindrical part 11 ofthe power transmission member is mounted by means of a cotter joint 12 on the driving shaft 13 of the motor mechanism, the centre of said shaft 13 defining a common rotational centre 18 ofthe device.
• a spacing sleeve 14 is mounted towards the motor mechanism box 9 around the cylindrical part 11 ofthe power transmission member 1.
• the disengagable lever 2 is mounted on the drive shaft 13 ofthe motor mechanism by means of a washer 19 and a screw 20.
• the disengagable lever 2 is freely rotatable about the common rotational centre 18.
• the power transmission release coupling 7 is mounted on one lever arm ofthe disengagable lever 2 , said coupling consisting of a U-profile 76, the legs of which having been cut at an acute angle at one end.
• the power transmission release coupling 7 is pivotally connected to the disengagable lever 2 via two screws 71 passing through the legs ofthe U-profile 76, fastened by screwing in the disengagable lever 2.
• a handle 77 extends obliquely downwards from the U-profile 76.
• a screw 72 with a helical spring 74 extends through an oval hole 73 in the web ofthe U-profile 76 and is screwed into the underside ofthe disengagable lever 2.
• a latch catch 21 is mounted on the second arm of said disengagable lever 2, said latch catch being defined by two cams 22 and an intermediate groove.
• the straight moment lever 4 is located above the power transmission member 1, journalled at the centre ofthe moment lever in the cylindrical part 11 of said power transmission member 1. In the upward direction the moment lever 4 is positioned by said spacing sleeve 14.
• the moment lever 4 has two arms, which in their ends are pivotally connected to said first and second pull-push links 5 and 6. Further, a latch stop 41 is mounted on the moment lever 4.
• a device here referred to as a latch lock 8 is stationary mounted on the motor mechanism box 9.
• Said latch lock 8 consists of a plate which is welded to the motor mechanism box and has one end cut at an angle.
• the disconnection unit 3 mainly consists of a round bar, in the following cold rocker latch 31, which extends at a right angle relative to the moment lever 4 mainly beneath but also somewhat beyond the upper surface ofthe moment lever 4; a shaft 32 which is partly threaded; a helical spring 33; and the above mentioned latch catch 21.
• the rocker latch 31 is in its upper end pivotally connected to the moment lever 4 and in the bottom end pivotally connected to one end ofthe shaft 32.
• the helical spring 33 is mounted around the shaft 32 and can be compressed by means of a clamping nut 34 and a retaining nut 35 against a projection 36.
• Said projection 36 which is connected to the movement arm defines a pivoted second holder for the shaft 32.
• the shaft 32 in the region of its connection with the projection 36, is provided with an elongated hole 37 which allows axial movements ofthe shaft 32. As is shown in Fig.
• the preferred embodiment includes a system for opening and closing the door, wherein the first pull-push link 5 acts on one door half via a first link arm 51, a second link arm 52, a door bracket 53, a wall attachment 54, a door stop 55, a front door leaf 56, and a rear door leaf 57, and wherein the second pull-push link 6 acts on the second door half via a first link arm 61, a second link arm 62, a door bracket 63, a wall attachment 64, a door stop 65, a front door leaf 66, and a rear door leaf 67.
• latch catch 21 is made of a self-lubricated plastic material.
• the rocker latch 31 When the unit 3 has released, the rocker latch 31 will spring back and stop against the latch stop 41, which acts on the upper part ofthe rocker latch 31.
• the latch stop 41 limits the spring back path ofthe rocker latch 31 in the released position. This makes a return ofthe rocker latch 31 to a position between the cams 22 possible by turning the disengagable lever 2 towards the moment lever 4, wherein the rocker latch 31 is brought towards one ofthe two cams 22 bringing the rocker latch 31 back to position between the cams 22 while the disengagable lever 2 readopts its original position parallel with the moment lever 4.
• the motor shall rotate in order to bring the unit 3 back to normal position, wherein the rocker latch 31 will be returned as in the foregoing. If on the other hand, the said unit 3 has released during a closing movement, the motor shall rotate for an opening movement in order to bring the unit 3 back to normal position.
• the rocker latch 31 In order that the closed door shall not be able to open by a manual pressure on the door leaves, the rocker latch 31 is locked by the latch lock member 8 when the door is in its closed position. The rocker latch 31 then cannot be tilted and hence it will prevent the door from being opened.
• the door can be opened and/or closed by disconnecting it from the drive shaft 13 of the motor drive transmission by pulling the power transmission release coupling 7 downwards, wherein the disengagable lever 2 is released from the power transmission member 1. Thereafter the door leaves can be operated manually even though the motor is at standstill.
