Description

The invention relates to a tilting door, in particular for a garage, comprising a panel or leaf intended to obstruct or release a passage by tilting in a door jamb mounted on the contour of said passage. Such panels move from a so-called open position in which they release the passage, to a so-called closed position in which they obstruct this passage and vice versa.

In the fully open position, the panel is horizontal close to the ceiling of the garage, and in the closed position, the panel is substantially vertical.

The passage from one position to another of the panel is achieved using driving means comprising: on the one hand a source of motor energy, such as for example an electric motor and / or a counterweight, or human energy; - On the other hand a connecting member such as a chain, cable, strap or equivalent. The connecting member is connected at one end to said motor element and at its other end to the panel. Generally, two connecting members are provided on each side of the panel.

For convenience, in the following, the concept of "source of motor energy" will be called "motor element".

The driving element is designed to simultaneously exert a force on the two connecting members which jointly transmit this force to the panel to assist its tilting.

The training of such a door panel must both: - Be uniform, smoothly - Require minimal effort, especially at startup - Ensure an ad hoc closure of the garage, without space between the panel and the doorframe - Being Quiet - Be done safely. In addition, the drive means must be able to be manufactured in a simple and economical manner, and in addition be installed quickly and easily. It has been proposed in a known manner garage doors which meet these requirements, by the French patent applications No. 1056441, 1056442, 1059161. The present invention aims to provide the solutions already proposed, which are satisfactory, an improvement. To this end, according to the invention, the tilting door device comprising a panel mounted in a door jamb delimiting an access opening, the door being mounted movable in tilting between two extreme positions, namely an open position releasing the passage and a so-called closed position in which it obstructs said passage, the door being associated with drive means comprising on the one hand a motor element, such as for example an electric motor and / or a counterweight, and on the other hand share at least one connecting member such as a chain, cable, strap or equivalent, is characterized in that there is provided two means of temporary attachment between the panel on the one hand and the body of the other hand connection, the two attachment means being in latching position in turn (alternately) on the panel. This simplifies the whole chain and pulleys and ensure a smooth and smooth training.

In the rest of the description, the qualifiers "superior", "lower", "high" and "low" of an element of the device are used as part of a normal installation of the device, that is to say relating to a substantially vertical concept of the panel in the closed position of the door relative to a flat horizontal floor.

In an advantageous form, the device comprises a single connecting member, without end. Each attachment means is associated with the organ or the connecting members. Advantageously, the association passage of the panel of the first attachment means to the second attachment means is performed when the panel is in substantially middle position, between the extreme positions, open and closed. More precisely, the median position is at 45 °.

Four return elements are provided, such as pulleys, rollers, toothed wheels, or the like, so that the connecting members or the connecting member form two parallel strands of substantially horizontal direction, and two parallel strands of substantially vertical direction, two of the return elements being close and located at the junction angle of the horizontal and vertical strands. Preferably, each attachment means consists of a projecting element, such as a finger, and is provided on the panel two complementary elements adapted to cooperate with said fingers. Said complementary elements provided on the panel are disposed substantially on two opposite end edges.

A preferred variant provides that a return member at one end of the horizontal strands is coaxial with the return member at one end of the vertical strands. According to said variant, said two return members are mounted on a common shaft, one of the return members being freely mounted on the latter and the other return member being fixed to said shaft, the latter being rotated by the means drive. Still according to this variant, the return member at the opposite end is mounted on an axis which is not strictly parallel to said shaft.

In an advantageous embodiment, said connecting member is a chain and the return members are toothed wheels. The present invention is now described using examples which are only illustrative and in no way limit the scope of the invention, and from the attached illustrations, in which: FIG. 1 represents a perspective diagram of a garage with a door device according to the invention, the door being in the intermediate position; - Figures 2, 3 and 4 are diagrams in side view of Figure 1, the door being in position respectively: fully closed, half open and fully open; - Figure 5 shows schematically in perspective a variant of the door device of the invention; FIG. 6 is a diagram in front view, along a vertical plane, of the device of FIG. 5. FIG. 1 schematically and partially shows, in perspective, a garage 1 defining a parallelepipedal space delimited by side walls 2 and 3 parallel, a ceiling 4 and a floor 5 horizontal parallel, a vertical bottom not shown and a front opening 6 rectangular. The opening 6 can be closed by a door panel 7 known per se, of rectangular shape complementary to the opening 6 The door 7 is pivotally mounted between a closed position where it closes the opening 6 (Figure 2) , and an open position where the opening is disengaged (Figure 4), the door then being close to and parallel to the ceiling 3. In Figures 1 and 3, the door 7 is shown in an intermediate inclined position.

The door panel 7 is slidably mounted in a doorframe by a guide system, known in itself, for example composed of guide rails cooperating with rollers mounted on the panel. The guide rails and the rollers are known to those skilled in the art who can refer to the patent applications cited in the preamble of the description. These means will not be developed in more detail here. The door is tilted by means of drive means including: - motor means, not shown in Figure 1, such as a motor or a counterweight; one or two flexible connecting members, here in this case a single endless chain associated with deflection elements, such as toothed wheels 11 to 14. - Fastening elements 8 and 9 of the door provided on the member or the connecting members, and able to cooperate with complementary elements provided on the door.

Alternatively, the member or the connecting members may be ropes or straps, and the pulley return elements. The drive means (motor and / or counterweight on the one hand and chains on the other) cause at least the return chain or chains.

The drive means are provided on one side of the door (they may alternatively be provided or on both sides of the door).

In the preferred embodiment shown, there is provided a single, endless chain, referenced 10, mounted on four idlers 11 to 14.

The single chain 10 thus comprises: two horizontal parallel strands, respectively upper 15A and lower 15B; and - two parallel vertical strands, respectively before 16A and 16B rear.

Two of the toothed wheels, a first 14 and a second 12, are close to each other and close to the junction between the ceiling 3 and the plane of the opening 6. These two gears are conventionally called "wheels" toothed angle ". The first wheel 14 is close to the junction angle between the ceiling and the opening, while the second wheel 12 is arranged in alignment with the first wheel with said junction angle and opposite said angle, and is shifted downward.

Figures 2, 3 and 4 show schematically from the side, the garage of Figure 1, for three positions of the door 7, respectively closed, half open and fully open. In Figures 1 to 4, the chain comprises two attachment elements 8 and 9 in the form of each finger or projecting element. The fingers 8 and 9 are placed on the chain so as to be separated by a length approximately equal to the length plus two vertical or horizontal strands. The side corners 7A and 7B of the door panel 7 associated with the means drive, comprise elements, on the one hand complementary to the latching fingers 8 and 9 of the chain, and on the other hand formed of curved parts forming hooks, respectively lower 17 and upper 18, concavity turned one; towards the other and towards the inside of the garage. With reference to FIG. 2, the door 7 is closed, in a vertical position, the hooking finger 9 being in engagement with the upper hook 18, and being located close to or against the first corner gear 14. starting position, the other gripping finger 8 is located close to or against the second toothed angle wheel 12. The fingers 8 and 9 are advantageously located downstream of the two toothed wheels, that is to say associated with both vertical strands 16A and 16B.

As soon as the motor means drive one of the toothed wheels, for example the toothed wheel 14, the endless chain 10 is driven according to the arrows mentioned in Figures 2, 3 and 4, facing each strand.

The moving chain drives the gripping fingers 8 and 9. Starting from the position of FIG. 2 for which the finger 9 is at the level of the vertical strand 16A just before the junction angle with the horizontal upper strand 15A, the finger 9 moves along the arrow f1 and horizontal 15A, towards the rear of the garage. The door being engaged by the upper hook 18 with the finger 9, it therefore accompanies the finger in its movement and moves in a tilting movement, combining rotation and translation, to arrive at the middle position of FIG. the door is guided by guide means known in themselves and not shown (rails and rollers). In the middle position of FIG. 3, the hooking finger 9 has reached the end of the horizontal upper run 15A, and is close to or against the upper rear pulley 13 and the opposite of the wheel 14. this time: the other finger 8 which was close to the second wheel 12 has moved (driven by the chain 7) along the arrow f3, downwards, to reach a position close to or against the lower pulley 11 and at the bottom of this pulley; and the lower part of the door, and in particular the lower hook 17 is translated in height to reach the finger 8 and engage with the latter. The movement of the chain 7 continues, causing the displacement: - of the finger 9 along the horizontal lower run 15B (according to the arrow f2); this causes the release of the finger 9 relative to the upper hook 18 of the door; and - the finger 8 (engaged with the hook 17) upwards according to the vertical front strand 16A, and thus the movement of the hook 17 and therefore the door which continues its tilting movement.

The door then tilts until reaching the position of Figure 4 completely open, where it is close to or against the ceiling and substantially parallel to the latter. The drive means (motor for example) are then stopped. In this position, the finger 8 is still engaged with the hook 17 of the door and located at the level of the first corner wheel 14 in the corner of the door. joining the vertical strand 16A and the horizontal strand 15A, while the finger 9 has reached the level of the second angle wheel 12.

When it is desired to close the door, the drive means are triggered and then drive the chain (FIG. 4), according to the arrows f'1 and f'2 for the horizontal strands and the arrows f'3 and f'4 vertical strands.

The finger 8 engaged with the hook 17 then drives the door in a downward tilting movement towards the middle position of FIG. 3, and finally reaches the closed position of FIG. 2 again.

In order to save space at the two so-called corner pulleys 12 and 14, an advantageous variant is shown in FIG. 5 (in slight perspective from the side) and FIG. 6 (in a vertical plane, rear view).

In this variant, the corner pulleys 12 and 14 are coaxial, of horizontal axis represented by a drive shaft 20 connected to a motor 21. The corner pulleys 12 and 14 are therefore at the same height but offset in the direction of the width of the door.

The single chain 10 passes around the pulleys 11, 12, 13 and 14 to form four strands, ie two horizontal and two vertical strands (as shown in the embodiments of Figures 1 to 4).

Referring to Figure 6, the lower pulley 11 is of axis 22 inclined at an angle "alpha" relative to the horizontal 23. to allow to take into account the axial offset between the corner pulleys 12 and 14. The vertical strands 16A and 16B are therefore not strictly vertical but slightly inclined at a theoretical angle of half the angle "alpha".
