elnes gate is possible, which is a comparatively 4; roße Releases area, but does not require much effort and also does not require much adjoining haum for its movement.

While most of the garage doors of the tilting type referred to below are satisfactory, but it is usually necessary to close the gate after driving the motor vehicle out of the garage, and before the vehicle can be driven into the garage, the door must be opened again. There have been gates of different kinds in the past Type has been suggested that open and close automatically, but was generally the one in question Mechanism very refined or complicated and expensive or the gates did not work reliably.

In general, there is no difficulty in physically opening the door prior to removing the vehicle or other contents from the garage, nor is it very difficult to physically close the garage door after the vehicle has been returned to the garage. Under normal circumstances it is inconvenient to close the door after removing the vehicle because the person who must close the door normally drives the vehicle; Likewise, when the vehicle is returned to the garage, it is difficult or inconvenient to open the door or gate because the person who must open the gate again generally drives the vehicle.

He; so it would be desirable to create a goal that is true physically opened to remove the vehicle from the garage and after return uni ?; of the vehicle in the garage must be physically closed, but it closes automatically when the vehicle is removed from the garage and opens automatically when the vehicle is to be returned to the garage.

The aim of the invention is to create a gate that meets these criteria.

According to the invention, an overhead door is also created which - when it is in its open position can be closed when a triggering device is actuated due to its own weight and - after it has been closed - automatically opens when the triggering device is actuated again by means of a counterweight system or the like .

The invention is based on the selective movement of dishes, with the gate in the open position the total counterweight for the gate is less than the weight required to hold the gate in this position so that the release device closes the Gate allows due to its own weight. Upon completion of the closing request is due to the order sufficient weight created in the opposite sense, so that when the triggering device is triggered, the Opening the gate he; directed total weight, pusher is from:

109327/0 307 · ''"'" _ _h

BATH ORIGINAL

the total weight that the door or gate is trying to hold in its closed position.

In a particular embodiment there are two counterweights provided, one of which is permanently attached to the gate or to a group of components attached to the gate, whereby the gate in a relatively small allowance in his The closed position is biased, while the other can be in one of two positions, it being in the one position has no effect on the goal and in the second position the first-mentioned counterweight assisted to change the preload conditions so that the door or gate opens normallywerwelse.

To make it easier to understand the invention and its implementation in practice, it is explained in more detail below on an overhead door for a garage using schemati cal drawings.

Fig. 1 shows the front in a perspective view the garage to which the door according to the invention has been attached, as well as the associated driveway.

Fig. 2 shows a section along the line 2-2 of Fig. 1 in the direction of the arrows and shows the gate mechanism dar in its position with the door or gate closed and before the start of the work cycle for Operation of the gate.

Fig. 3 shows in a section along the line 3-3- of Fig. 1, the arrangement of the bolt or locking hook (latch) at the bottom of the gate.

FIG. K shows a partial view of the door from the rear, the mechanism in the same position as it is shown in FIG.

FIG. 5 shows a view of the lower part of the gate and is equivalent to the section of FIG.

Fig. 6 shows in a section along the line 6-6 of Fig. the suspension device on the side of the gate which is opposite the side shown in Fig. 2 and ^ J-.

FIG. 7 shows a view similar to the view of FIG is similar, but shows the position after the initial opening of the gate.

Fig. 8 shows a view which is similar to the view of Figs. 2 and 7, but the door after a second opening represents.

The door comprises a plate 10 which can be moved from a first position, as shown in FIGS. 1 and 2 and in which it covers the garage opening, to a second position, as shown in FIGS. 7 and 8 and in which it is in a substantially horizontal position at or near the upper part of the door opening 11. The gate is on one

Side with an arm 12 flushed on the inside and on the

109827/0307

the other side is provided with a similar arm 13, the arms being attached to the gate near the rilttellinle of the gate and the free ends of which are connected to pivots 14, 15 carried by support plates 16, 17 which in turn are located near the corresponding one Side of the door opening into the garage. The arrangement is such that there is a turning or pivoting moment about the pivot pins 14, 15, which "leads to the gate tmxss trying to assume its closed position. The arms 12, 13 and the position of the pivot pins 14, 15 are arranged so that the door fits neatly and neatly into the opening in its vertical position and fits slightly below the upper end of the door opening 11 in its horizontal position. In order to prevent the door or gate from lifting in a true arc of a circle, second arms 18, 19 are provided, many pivot pins 20, 21 on the support plates 16, 17 and at their other end with lugs 75-76 connected to the gate. The arms 18, 19 each have a slot 22, which is located on a locking pin 23,

The arrangement is such that when the door or gate is fully closed, as shown in FIG. 2, the gate for a vertical Position set and can be locked in the required position by means of the locking pin 23.

109827/0307

On the arms 12, 13 extending from the front of the gate to the pivot pins 14, 15, outwardly extending arms 24 and 25 are attached, each supporting a counterweight 26, and the counterweights are arranged so that they generate a torque or create a pivoting moment about the pivot pins 14, 15 in the direction, many being opposite to the direction in which the first-mentioned torque tries to close the gate, but the last-mentioned torque being of a smaller magnitude. There?; ^x or will therefore normally be in its closed position, but the work required to open the i'ores is reduced to a minimum and the apparent weight of the gate appears to be to a person opening the gate. As can be seen from the drawings, the counterweights are suspended by pivot pins 27 on arms 28, which in turn are connected by pivot pins 29 to the outwardly extending arms 24-25. On each of the arms 24, 25 a movable stop (stop) 30 is attached to the deoi; Counterweight 26 supporting associated arm 28 can rest. This arrangement serves two purposes. First, the moment of the counterweight 26 about the pivot pins I ^ or 15 can be varied by varying the angular position of the arm 28 with respect to the arms 24 and 25, respectively. In this way, the resulting pivoting or torque, which causes the door to close or open, can be varied without the entire geometry of the system having to be changed. Furthermore, the center of gravity of each counterweight 26 is automatically adjusted around the pivot pin 2? So as to help balance the momentum of the gate when the gate closes.

109827/0307

The actual shape and arrangement of the counterweight can however, can be varied according to requirements.

The remaining parts of the actuation arrangement of the gate are - as will be described below - attached only to one side of the gate, but could also be arranged on both sides of the gate. The additional parts comprise a catch member 31 which is mounted on a pivot 32 which is located on the support plate 16 or an extension of this plate and which has a forward arm £ 33 on which an upwardly directed rod Jk- is mounted, the purpose of which is further described below; the rod or rod Jk- extends through an apertured plate 35 'and above the plate 35 a helical spring 36 is mounted around the rod Jk- and held under pressure by an adjustable collar 37 so that normally the arm 33 is pulled upwards and thereby the latch section 38 is in its lowest position. The pawl arrangement is intended to interact with an extension 39 located on the arm Zk- which has a section HO in which there are two spaced apart parts or sections' +1 which receive the pawl.

When the gate is opened, the section kO touches the latch section 38, which lifts the sloh due to the rotation around its pivot and the compression of the spring 36,

109827/0307 " ⁹ "

so that the pawl portion J8 ramps to the first of the pawl receiving portions t41 and then a second ramp to the second of the pawl receiving portions. At this point the gate is open, like from Pig. 7 can be seen, and the sisistjc can only be closed when the lock is released by moving the plate 33 downwards. The latch actuating device of the invention may take various forms and three such forms are shown in the drawings. The first device consists of a hydraulic or pneumatic cylinder 42, the piston 43 of which is in close proximity to the arm 33 of the locking device, and this cylinder is tread via an ear, for example a flexible hose, with a compressible running or driving surface (tread ) 44 connected, which is attached in such a way that a vehicle driving out of the garage drives over it.

If the first wheel of the vehicle drives over this running surface or this step 44, the piston of the cylinder 42 moves downward, the oil locking device rotates about its pivot 32, so that the part 38 leaves the recess 41, and the lock then reverses back to its original state and engages in the second recess 41. If the second wheel of the vehicle drives over the running surface or the footboard 44, the lock is moved again; on this occasion, when the lock returns, it is released from part 40 in its original state ) and the door closes again sioh resulting turning "- or * Sohwenkmoment, which was discussed above.

100027/0307 - ίο -

There can be as many pawl-receiving sections 41 may be used as required according to the number of wheels of the vehicle using the garage. Everyone Section '+1 represents a wheel on the vehicle.

The alternative actuation arrangements include one manually operated plunger 45, which is connected to a cord, chain or the like. 46, which is connected via a pulley runs and is connected to the arm 33 so that the closing process can be initiated from outside the garage; the retracted plunger causes the portion 38 from Section 41 is separated so that the door can close · The other arrangement consists of another cord, chain or the like. 48 inside the garage, this cord,

works or chain or the like in the same way as the plunger 45 / can be operated so that the door can be released from inside the garage.

In an alternative, not shown embodiment the hydraulic or pneumatic piston or ram can be replaced by a cable-operated arrangement, wherein a lever is depressed when a vehicle moves over a lever arm, and by depressing a shortening or lengthening of the cable for actuating the lock is brought about.

It can therefore be seen that the garage door 10 can be opened with little effort due to the counterweights 26 and is held in its open division by the positive or inevitable interrelationship between the locking device 31 and part 1. If, however, the vehicle is moved backwards in the garage via the footboard ^ k or driven outside via the footboard hk , the lock is released and the closing moment allows the garage door or garage door to be closed. Depending on the selected particular arrangement, the velocity v of closing the door is controlled: the He.

The closing speed can be regulated or controlled by using one or more vapors. built into the mechanism, and we have shown such a damper in the drawings, which is arranged as damper k9 between the arm 25 and the frame structure. If necessary, an additional damper can be placed on the other side of the door, but in practice this has not been found necessary and the space available for such a damper is not great.

The arrangement and actuation is then ao, as shown in Fig. 2 and 7 can be seen, whereby originally the gate is closed, then it is physically moved into an open position in which it is locked, as can be seen from Fig. 7, whereupon the lock is released and the gate is back to its initial pitch, which according to FIG. 2, returns.

109827/0307

To cause the door or gate to open automatically, the counterweight is increased, and this is achieved by creating a second counterweight 50 »the as Auxiliary weight is referred to and is supported by an arm 51 around the same pivot 14 as the counterweight 26 is rotatable but can rotate freely with respect to the gate and the first counterweight 26. The auxiliary weight 50 is attached to an arm 52 which via a pivot pin 53 is connected to the arm 51, and an adjuster 54 is also connected to the arm 51. This arrangement is identical to and works in the same way as that A similar arrangement belonging to the counterweight 26, and by changing the setting point or Hegel part 54 it is possible to determine the effective torque or torque of the Auxiliary weight 50 to control, thereby controlling the speed of movement of the gate, as in the following will be further described.

A pin 55 is attached to the arm 51 which extends beyond the arm Zk and serves two basic purposes. The first purpose is that when the arm rotates freely about its pivot pin 14, the pin 55 rests on the rear part of the arm or the rod 24, and the pivoting or torque about the pivot pin 14, which causes the opening of the gate, then consists of the sum of the moments of the counterweight 26 and the auxiliary weight 50, and if the moment of the Hilßsgewlohtea 50 is set accordingly, this moment can be slightly greater than the pivoting or torque,

- 13 109827/0307

that keeps the gate closed, and so the toi 'opens under the action of the two counterweights. When the door is open under these circumstances, it assumes the position shown in FIG. 3, from which the position of the two arms relative to the pin 55 can easily be seen.

To control that, however, a .56 latch is around a pivot

stored
57 rotatable aHgsfcEasfefc, which is attached to the frame of the gate or - as shown - on an attachment 5Ö of this frame; this latch is provided with a spring 59 by which it is normally set in its fully down position, as shown in Fig. 8, with an extension 60 thereon being able to bear against part of the goal frame. The nose 6l of the bolt is arranged so that when the arm 51 is raised, the pin 55 $

of the bolt
slides under the iiase / or lifts it against the force of the spring 59 until the pin slides past the switch 62; At this point the bolt falls down and the pen is behind the school. held around the pivot pin 14.

In order to release the bolt 56 if necessary, an actuating device 63 is attached to the ann 24 and is movable about a pivot 64. The arm 63 is normally biased to be in contact with the stop also mounted on the arm 24. The outer end of the arm is provided with a roller or the like 66, which is arranged to turn with an extension 67 on the bolt 56 in appeal SIA, ftebgaoht and many others and to lift the bolt when the arm

64
is rotated around its pivot /. The rotation will

reached by a rod 68 supported on a pivot 69 and in turn by rod 34 rotated / Γ polygamy pretensions the bolt 31 by means of a spring.

The arrangement is made so that when the. Cylinder 42 and when the gate is in the position shown in fl Makes contact with the extension 67 on the bolt, thereby releasing the bolt from the pin 55, and once the pin acts on the arm 24 the total torque is such that the gate opens. Since this position is only reached when the door is closed, this process normally takes place when the vehicle is driven to the garage and so when the footboard 44 is pressed down the door or gate opens automatically at this point in time, so that the Vehicle can be driven into the garage.

After completion of this opening process, the gate assumes the position shown in FIG. 8 and the arm 68 can the bolt Do not lift 56 because the actuating arm 63 is missing between them. The door or the gate must then be hand getting closed; in the drawings is an arrangement shown, in which a cord 70 runs over a pulley and is provided with a handpiece 72, what * \ raw the additional or auxiliary weight 50 by downward movement of the HandstUokes 72 returned to its locked position be Joaniu JJine, .such movement causes

the arm. 51 locks itself against the shoulder 62 of the wing 5b and the door will close automatically, since its closing moment is then greater than the moment exerted by the counterweight 26.

Alternatively, the gate can simply be closed visually from the outside by a downward movement, since the pin 55 causes Pich to lift the arm 51 with the arm Zk.

The type and manner of closing depends, of course, on whether inan wants to close the for from within, z.ß. if the Users stay in the garage with the door closed. ■. Punched or if an alternative exit door comes out of the Garage is available, or from the outside, which will be the case if there is no further exit from the garage is available.

It must be seen clearly that the gate is in a four-step Work process is working. In the arbitrary first position the gate is closed and both counterweights are in their raised position as in 3 "ig. 2. In the second position the gate has been physically opened, the latch 31 held to hold the J-Or in its to leave the open position, the counterweight 26 is located in its lower position and the auxiliary weight 50 in his highest position. The third position occurs when the bolt 31 is actuated and the gate closes. It should be clear that at this point the latch 56 cannot be released because the arm 24 under-

109827/0307 " ^l6 "

supported arm 63 is located at a distance from the latch. The third position is reached when the gate is back opens, but on this occasion both counterweights are down, i.e. the position in which the gate is automatically opens. The fourth position is available when the gate has been physically closed by either the auxiliary weight 50 is raised or the gate is moved about its pivot until the arm 51 is held by the bolt 56.

For safety reasons and to ensure that the gate is held against movement after it is closed a locking arrangement has been presented: the in connection with the other work functions of the gate « cooperates and in * Ig. 3 and 5 is shown. This lock essentially comprises a pair of rods 77 'which extend across the width of the gate and are in slide bearings (.journals) 78 are supported, and aer near their End up. The poles can be in the i'ittte of the gate with connected to a rotatably mounted plate "a, in which each can be attached inside (each can be joined inwardly), and this plate can be operated by a handle 79 outside the gate. Usually this handle is provided with a lock to report unauthorized entry from outside the gate.

The rod 77 extends through the tubes 78 and terminates close to the edge of the gate and behind the door frame. Aligned with the end of the rod is a Plunger 79, (ram), the one outwardly extending

109827/0307 -17-

Has piston 80, which most expediently extends coaxially to the rod 77. The plunger or cylinder 79 is supplied by a tube or hose 81 which extends at 82 from a connection point in the vicinity of the plunger or cylinder 42, so that when the plunger 42 is actuated, the plunger 79 is also actuated the rod is adapted to an upwardly extending locking part which, as from ^x 'ig. 3 and 5 can be seen behind a stop 84- and thus keeps the gate closed.

If the plunger 79 is actuated, the rod 77 is moved inwards and the part 83 is released from the stop 84-, and so is the lower end of the gate is released and can rotate, provided the appropriate lock 31 or 56 was released. The movement of the rod 77 can be created so that the rods can move despite the fact that the handle is locked.

The stop part 84 is rotatably mounted on a shaft 85 and is provided with a spring preload by means of a helical spring 86, by means of which it normally moves into the FIG. 3 is depressed, but can be moved upwards. The downward movement takes place in. two different circumstances. In the first case, if sieft closes the gate and the part 83 meets the front end of the stopper 84, in the itöhe the shaft 85 'and the M _o ment of l'Oreo causes the stopper 84 moves upward, so that the part 83 can slide behind it, to which tent point it returns to its initial division.

109827/0307 - 18 -

Should the 'J-Or be manually either by actuating the piston or the cord 48 will be released at one end the shaft 85 an additional cord 8? attached to the runs over a pulley 86 at its other end and is connected to it, where the same 86 is rotated by the cord attached to the piston 45 or by the cord 48. With such a rotation the stop 84 also rotates so that it rests the part 83 no longer holds, and when the movement of the piston or the cord 48 releases the latch 56, provided the gate is closed, then the door or gate can open because its lower * end is free, otherwise the Arrangement as in »ig. 2 is shown.

Although an embodiment of the invention has been shown, in which the gate is effectively balanced by a pair Counterweights, which are rotatably mounted on arms, the invention can also be applied to other types of gates and Doors or movable panels can be applied. Many

The invention can also be applied to goals or panels that do not need counterbalance, e.g. Sliding doors which can run on inclined rails so that they normally occupy one of their two positions and there is a counterweight or other actuating means which can only be connected to the door after a predetermined sequence of operations, wherein the "-L'or is physically moved from one position to another; a latch is operated to release the ' ^χ ον so that, due to the inclination of my rail, it returns to the other of the two positions, and is at this point in time the counterweight or other i-i means functionally connected to it, so that when another latch part is triggered, the door returns to its previous position, even if this necessitates an increase in the potential energy of the door and thus work has to be performed It is part of this invention to be considered, provided that they come within the scope of the following claims.
