Definitions

• the invention relates to a garage door drive device or the like guided in its movement by guide means, comprising a motor and a mechanical connection between the motor and the door.
• the invention relates to doors with tilting movement as well as sliding movement doors, such as tilting, pivoting, sliding or sectional doors.
• the most commonly used garage doors are overhead doors and sectional doors with vertical opening and closing.
• the drive devices generally used for these doors include a rail fixed to the garage ceiling, a rail in which a carriage moves connected by a rigid arm to the top of the door.
• Patent CH 689,435 describes an installation of this type for a tilting door
• document WO 96/39740 describes an installation of this type for a sectional door guided by two lateral rails. In the closed position of the door, the rigid arm and the carriage prevent the door from being broken into.
• Segmented doors are also known which are driven by two cables which are wound on drums driven by a motor placed against the lintel of the doorway. Such devices are described in documents WO 92/09777 and 99/07971. These devices allow the door to be raised to the level of the garage ceiling, but they are not applicable to standard doors. In addition, if the installation is provided with means for compensating for the weight of the door, it is necessary to provide a second pair of cables for driving the door on closing.
• the object of the invention is to offer a standard drive device which overcomes the drawbacks of central rail devices, that is to say without lintel height constraint, this device also having to be easy to install for all doors. .
• the drive device according to the invention is characterized in that the mechanical connection consists of an extendable arm.
• extendable arm is meant an arm capable of growing and extending from a fixed point.
• This device is intended in principle to be fixed to the garage ceiling.
• the removal of the cart and its rail allows the door to be raised very close to the garage ceiling.
• the motor and the space in which the extendable arm is removed occupy only a reduced space and the assembly is convenient to install.
• the device according to the invention can be delivered in one piece with regard to its dimensions and not as in the prior art in two parts, on the one hand, the motor and, on the other hand, the rail. This saves the user from having to perform an initial assembly before installation, which saves time and facilitates installation.
• Extensible arms for example in the form of jacks or parallelogram systems, are well known. It has even been proposed in the document DE 35 32 013 to use an extendable arm of the jack type to deploy a sun visor in front of the rear window of a car and, according to document EP 0 039 632, to deploy the arms d 'an awning with two cylinders, but no one has thought so far that it could be very interesting to use an extendable arm to drive a garage door. The rigidity of the extendable arm was probably considered to be insufficient to ensure the safe movement and retention of the door. However, if necessary, security can be ensured by auxiliary means.
• beam-shaped structures are also known which are formed by the assembly of two chains, the links of which have a particular conformation.
• the extendable arm consists of superimposed profiled elements sliding one inside the other and stackable in a magazine, the elements being deployable in an oblique position along an axis of movement corresponding to the axis of the extendable arm, the connection of the elements between them being provided by part of the length thereof.
• the profiled elements are advantageously provided on a lateral face with a rack parallel to the axis of the arm for their drive by a pinion driven by the motor.
• the profiled elements are provided with mutual locking means operating in the extended position and mutual unlocking means operating when the elements are removed.
• the locking means consist of retractable lugs pushed by an elastic means, these lugs preventing the removal of an element on the neighboring element and the unlocking means consist of shoes repelling the lugs of the element to retract under an already retracted element.
• the drive device advantageously comprises means for orienting in an oblique position the deployable elements for their deployment.
• these orientation means consist of a movable guide having an oblique side profiled as one of the sides of the elements deployable on which is engaged the first deployable element upstream.
• the orientation means consist, on the one hand, of a pair of lateral pins on each deployable element and, on the other hand, of a pair of parallel grooves in the area of leaving the store, grooves in which the pins engage and slide, these grooves being oriented in the direction of deployment.
• the orientation means consist, on the one hand, of a lateral rib on each element and, on the other hand, of a groove in the outlet zone of the magazine, groove in which are engaged and slide successively the ribs of each element, this groove being oriented in the direction of deployment.
• the extendable arm consists of elements hinged together, foldable and stackable in a store and provided, on one side, with a rack, the device further comprises means for aligning the elements articulated according to the direction extension and means for holding in the aligned position.
• the means for holding in the aligned position comprise means for automatically locking the joints and means for unlocking the joints operating during the retraction of the extendable arm.
• These locking means advantageously consist of a locking member mounted to move in one of the elements near the articulation, and of an elastic means tending to keep this locking member in the locked position, engaged in the neighboring element.
• the unlocking means consist of a fixed ramp and an unlocking finger slidably mounted in the element in which the locking member engages, the ramp being arranged so that it pushes the finger unlocking, this finger in turn pushing the locking member.
• the articulations of the elements are formed out of the alignment of the elements, alternately on one side and the other of this alignment, and that the aligned elements bear frontally one against the 'other by their ends so as to form a beam stressed axially and the ends of the elements are plane and perpendicular to the alignment.
