Definitions
- the present invention relates to an arrangement for a spring fracture safety device intended for a closing element for an overhead sliding door or similar capable of being moved between a raised and a lowered end position, which can be attached to a door actuating spring and controlled by tracks extending along the intended path of movement of the door, continuous guide rollers or similar control devices.
- the principal object of the present invention is, in the first place, to make available an arrangement of the kind indicated above, which is caused to function efficiently and reliably in the event of spring fracture, irrespective of where along the length of the spring fracture occurs.
- Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that one free end of the actuating spring is capable of being attached via a movement transfer device to a release device for a door braking element interacting with a number of said guide rollers, etc., which braking element can be caused to move between a position in which it is ready for release and a braking position, in which positions the element is respectively kept withdrawn, so that said guide rollers are able to pass freely along the tracks in question, and is caused to project, so as to produce a braking effect by interaction with a door guide roller.
- Fig. 1 illustrates the invention applied to one side of the track for an overhead sliding door and arranged in a so-called "braking position";
- Fig. 2 illustrates the spring fracture safety device in an active braked position in which a door control roller is being restrained
- Fig. 3 illustrates a part of the arrangement in a released, "braking position"
- Fig. 4 illustrates said part in a so-called position in which it is ready for release
- Fig. 5 illustrates in perspective view a release device which is a constituent part of the arrangement in its position in which it is ready for release;
- Fig. 6 illustrates, the release device in a separated position and partially sectioned.
- One free end 1A of a helical actuation spring 1 which may be supported by a number of holders 3 capable of being attached to the upper part of a door opening 2, and which is capab le of being connected in a previous ly disc losed manner to a door panel 6 or similar closing element provided with a number of guide rollers 5 or other similar guide devices running in guide tracks 4 extending along the lateral edges of the door opening, is capable of being attached to a release device 7 for a door braking element 8 interacting with a number of said guide rollers 5, etc., via a movement transfer device 9 conveniently in the form of a cable.
- Said cable 9 which is preferably accommodated in such a way that it is protected inside a cable protector tube 10 extending between said end 1A of the spring and the door braking element 8, is connected by one of its ends 9A conveniently to a sleeve 11 threaded onto the end 1A of the spring, which sleeve exhibits a hole 12 through which the end of the cable passes and is then attached to the cable 9 once more by means of a suitable attachment 13.
- Said end 1A of the spring conveniently extends directly outwards from the spring 1, more or less tangentially, and is capable of interacting with a stop 14 on the spring holder 3, which stop is so arranged normally as to function as a support for the end 1A of the spring when the spring 1 is held under tension during normal operation of the door and its spring 1.
- a recess 15, which matches the form of the end 1A of the spring, is conveniently provided in said stop 14 for the purpose of securely retaining said end 1A of the spring and preventing the spring 1 from rotating when it is working and is placed under tension.
- the door braking element 8 is so arranged as to be capable of being moved between a position I in which it is ready for release, as illustrated in Fig. 5, and in which position I the spring fracture safety device 21 is maintained in a readiness position in which the guide rollers 5 are able to pass freely along the track 4 in question in order to be capable of being released automatically in the event of fracture of the spring 1, and a braking position II, as illustrated in Figs.
- the door braking element 8 may consist of a brake block 23 which is provided with a number of brake heels 24 projecting in the same direction away from the block 23.
- Said brake block 23 is capable of being actuated in its position I in which it is ready for release by a number of release springs 25 executed from curved spring material, or is spring-actuated in some other way so as to be capable of being released, if necessary.
- release device 7 consisting of a pin, for example, which is attached by its one end 7A to the end 9B of a cable, and the other end 7B of which is capable of being accommodated in a hole 26 in a tongue-shaped attachment 27 which projects in a direction away from the bottom 28A of a trough-shaped casing 28, inside the internal cavity 29 of which the door braking element 8 is capable of being accommodated.
- the attachment 27 is so arranged as to be accommodated by a suitable opening 30 in the brake block 23.
- the springs 25 can be so arranged as to be capable of making contact respectively with the bottom 28A of the holder and with the rear surface 23A of the brake block, and may exhibit guide pins 33 projecting, for example, from their central part 25A and thus also from the bottom 28A of the casing, which guide pins are capable of being accommodated by suitable holes 34 in the brake blocks 23.
- the casing 28, which can exhibit fastening devices 35 enabling it to be fastened to, for example, the outside or some other surface of a door guide track 4, as clearly shown in Figs. 1 and 2, also exhibits an elongated opening 36, for example, on one of its sides, so as to permit the cable 9 to be introduced as far as the intended connection with the attachment 27.
- Said springs 25 are accommodated in a space 28B formed between the bottom 28A of the casing and the brake block, whilst the brake block 23 and its brake heels 24 are kept fully retracted inside a space 28D defined by an opening edge 28C.
- the brake heels 24 can exhibit a relieved section 37 so adapted as to be capable of accommodating a part of a guide roller, etc., of the kind in question, so as to function as a restraint for said guide roller 5 and conveniently also for a swinging roller holder 38 attached to the door element 6, which holder is described in more detail below.
- the roller holder 38 consists of two swinging arms 39, 40 which are attached at one end 39A, 40A to a swinging axle 42 accommodated in a bearing 41 attached to the door panel 6, so as to be permitted to be pivoted about said bearing 41.
- a tube 43 is securely attached to the arms 39, 40, and a bearing shaft 44 for a door guide roller 5 is accommodated by said tube 43, as illustrated in
- the swinging arms 39, 40 are attached by means of bolted connections 45 to a bearing plate 46, which is secured to the inside 6A of the door by means of screws 47, each of which bearing plates has its own flange 48, 49 projecting at right angles from the door panel 6.
- the bolts 45 are accommodated in curved openings
- a suitable bearing component 52 which is accommodated by an adjacent section 6' of the door panel and which is attached to the shaft 42 by means of a tongue 53 containing a hole, enables a link to be provided between two sections 6 1 , 6 2 of the door panel which are connected together.
