    The invention describes an auxiliary device (1) for garage doors (200) located between a ramp (300) and a horizontal floor (400) and that move between open and closed positions operated. The device comprises: a flat platform (2) for supporting the wheels of a vehicle (100) having an edge coupled by means of an articulation (3) to the ramp (300) or the horizontal floor (400); and a cable (4) connected between the platform (2) and a driving element (210) or the door (200). Thus, when the door (200) is closed, the cable (4) pulls up said platform (2) until it is arranged in an essentially vertical position when the door (200) reaches the closed position and, when closed, the cable (4) allows said platform (2) to sit between the ramp (300) and the horizontal floor (400) when the door (200) reaches the open position.

    [0001]
    [0002] Auxiliary device for garage doors
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The object of the present invention is a device that can be attached to a garage door with the purpose of increasing the angle of attack in cases where said door is located at the beginning of an ascending ramp to enter said garage.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The access to many current underground garages is done by a descent ramp that ends in the floor plan to which the garage is located. This configuration, which in principle does not imply any inconvenience, can be problematic in the case of ramps with steep slopes due to the fact that the front end of some vehicles may hit the ground at the end of the descent of the vehicle through the ramp.
    [0011]
    [0012] This problem is shown schematically in Fig. 1. A vehicle (100) is descending a ramp and, just at the end of it, a contact occurs between the front of the vehicle (100) and the ground. This contact occurs when the angle of attack of the ramp (a), that is, the angle formed by the ramp with the horizontal is less than or equal to the angle that forms the longitudinal direction of the vehicle (100) with the line that joins the contact point (P1) of the wheel with the lowest point (P2) of the front end of the vehicle (100). Therefore, the lower the vehicle (100) or the longer its front portion, the lower its ability to travel inclined ramps without touching the ground with its front end. This problem is especially aggravated during the descent of the ramp, since the front part of the vehicle (100) descends even lower due to the inertia and greater weight that the shock absorbers support in that position. In short, this problem means that some vehicles can only access certain garages at the cost of repeatedly hitting the ground.
    [0013]
    [0014] Currently there are some documents that describe ramps adapted to different types of vehicles to save the difference in ground height to the platform of the vehicle in question.
    [0015] Document US2541288A describes a device that, anchored to the vehicle itself, descends to save the height of the platform, that is, the platform is part of the vehicle and obviously has no ground connection, unlike the system presented in this document, which is articulated on the ground and which, due to its composition and movements, is intended to increase the angle of the garage ramp.
    [0016]
    [0017] Document EP1686032A1 refers to a folding ramp for vehicle access that is part of the door itself, that is, the door is deployed and being open serves as a ramp to rid the height difference between the ground and the platform. The differences on the patent presented here are similar to those of the previous document.
    [0018]
    [0019] Document CN206801127U discloses a motorcycle system, similar to the previous one, where the door, when opened, becomes a ramp and allows access to a container.
    [0020]
    [0021] Document US2011163565A1 describes a device by which the door, when opened, becomes a ramp and allows access by small vehicles adapting to different access heights.
    [0022]
    [0023] However, none of these documents solves the problem described, since they are not intended for access to a garage through an existing ramp but for access to a vehicle through a mobile ramp.
    [0024]
    [0025] Therefore, there is currently a problem in this field that is not yet satisfactorily resolved.
    [0026]
    [0027] DESCRIPTION OF THE INVENTION
    [0028]
    [0029] The present invention solves the above problem thanks to the provision of at least one platform that rests on the intersection zone between the ramp and the horizontal floor to decrease the angle that they form with each other by dividing it into two angles corresponding to the two changes of tilt to one side and another of the platform. This platform will be connected to the door's own drive mechanism so that, when the door is opened, it descends until it rests on the ramp and the horizontal floor in the position described, while, when the door is closed, it is collected in vertical position. Therefore, as will be seen in detail later in this document, the device of the present invention can be installed easily and quickly in any existing garage door, regardless of its mode of operation.
    [0030]
    [0031] The auxiliary device for garage doors of the invention is applicable to garage doors located in an intersection line between a garage access ramp and a horizontal floor. This situation occurs, for example, when the entrance door to an underground garage is arranged at the end of the ramp that descends to said garage, or when the entrance door to an elevated garage is arranged at the beginning of the ramp that ascends to the garage In either case, it is assumed that the garage door is configured to move between an open position and a closed position driven by at least one sliding or rotating drive element.
    [0032]
    [0033] The driving element that displaces the garage door can be of any type in general, although in the current garage doors it is common to use an electric motor that drives the opening or closing of the door in various ways, such as, for example, by moving a sliding guide connected to the door in the case of vertical sliding doors, by means of a connection to the rack-type door in the case of horizontal sliding doors, or others. In any case, it can be interpreted that the driving element, or any of the auxiliary elements directly moved or driven by the driving element, describes a sliding or rotating movement that is subsequently moved to the garage door in the most convenient way.
    [0034]
    [0035] In this context, the device of the invention basically comprises two elements: a platform for the passage of the vehicle and a cable connected to the platform for deployment and collection. Each of these elements is described in more detail below:
    [0036]
    [0037] a) Platform
    [0038]
    [0039] It is at least one platform, normally flat, for the support of the wheels of a vehicle. In this context, the expression "normally flat" refers to a platform that is essentially plane-shaped, although it is not necessarily completely smooth or free of relief, that is, without ruling out the presence of small curvatures or similar, as well as the existence of textures such as nerves or the like, for example, to avoid landslides. The platform can be formed by a single rectangular plate with a width greater than the width of the axle of a vehicle (that is, the distance between two wheels of the same axle).
    [0040] Alternatively, in a preferred embodiment of the invention, two separate coplanar platforms are used a distance approximately corresponding to the width of the axle of a vehicle and connected to each other by a profile. In any case, the platforms can have any suitable shape, such as a polygon shape with four or more sides (square, rectangle, etc.). The profile provides rigidity to the assembly so that both coplanar plates move together as a whole. In addition, the profile has a width similar to the width of the garage door, so that it provides a connection point located at the foot of the position where the driving element of the door is normally located. On the other hand, the distance between the platforms, or the width of the platform if it is configured as a single plate, can be between 140 cm and 200 cm.
    [0041]
    [0042] This platform, or platforms, has an edge coupled by means of an articulation to the ramp or to the horizontal floor in an adjacent position and parallel to the line of intersection between ramp and horizontal floor. The joint can be configured in any way as long as it allows the platform to alternate between a position where it rests in a slightly inclined position on the ramp and the horizontal floor, and an essentially vertical position. For example, a hinge or a cylindrical ball joint can be used. As for the coupling of the platform to the ramp or to the horizontal floor, the most suitable one will be chosen taking into account both the closing direction of the garage door and the side that is outside the garage. Preferably, the platforms will be on the inner side of the garage when the door is closed.
    [0043]
    [0044] b) Cable
    [0045]
    [0046] It is at least one cable that has a first end connected to the platform and a second end connected to the drive element or the door. It can be any type of cable, including non-metallic cables, that is capable of supporting the weight of the platform to move it between the two positions described. Naturally, the connection point of the first end of the cable to the platform will be sufficiently separated from the joint.
    [0047]
    [0048] In this context, the expression "connected to the drive element" referred to the second end of the cable refers not only to a direct connection to the drive element, understood as an electric motor or similar, but in general to the connection of the second end of the cable to any mobile element driven by the driving element, including any means used to transmit the motive movement to the door. Similarly, the expression "connected to the platform" includes not only the direct connection to the platform itself but also a connection to any element attached to the platform.
    [0049]
    [0050] Thus, when the drive element is actuated in the direction of closing of the garage door, the second end of the cable moves in the opposite direction to the platform. As a consequence, the first end of the cable pulls up said platform and rotates it around the joint until it is arranged in an essentially vertical position when the door reaches the closed position. Conversely, when the driving element is actuated in the direction of opening of the garage door, the second end of the cable moves towards the platform so that the first end descends to allow said platform to rotate around the joint because of the gravity until it sits between the ramp and the horizontal floor when the door reaches the open position. As will be described later in this document, in this context it is important that the first end of the cable follows an upward / downward movement respectively when the door is closed / opened, since it must pull up or drop the platform.
    [0051]
    [0052] Therefore, this new device solves the previous problem in a simple and economical way, and also adaptable to any existing garage door. The platform rotates until it rests in the area of the intersection between the ramp and the horizontal floor when the door is opened, and turns in the opposite direction until it is essentially vertical when the door is closed. To install it, in the simplest cases it is only necessary to couple the platform to the desired position of the ramp or horizontal floor through a hinge or similar, and connect a cable between the platform and the driving element of the garage door.
    [0053]
    [0054] In a preferred embodiment of the invention, for a garage door provided with a sliding vertical sliding drive element that ascends to move the door to the closed position and descends to move the door to the open position, the second end of the cable is connected directly to the driving element. This means that it is not necessary to use any auxiliary element to modify the direction of the movement or to transform a rotation movement into a translation movement. Simply connect the cable to the driving element, including any part of the garage door opening / closing mechanism that is moved directly by the driving element.
    [0055]
    [0056] In another preferred embodiment of the invention, for a garage door provided with a rotating horizontal sliding sliding drive element, the device comprises at least one pulley coupled to an upper portion of a garage door frame through which a portion passes intermediate cable between the first end and the second end. That is, in this case it is necessary to use a pulley system to transform the horizontal rotating or sliding movement of the driving element into the essentially vertical movement of the cable that drives the platform.
    [0057]
    [0058] In a more preferred embodiment of the invention, the device of the invention further comprises at least one cam or spring in an intermediate portion of the cable between the first end and the second end to transform the uniform movement generated by the driving element into a movement with some sections faster than others depending on the lifting needs of the platform. For example, in the case of a horizontal closing door, it may be necessary to quickly raise the platform at the beginning of the movement to make way for the garage door. A cam or spring properly designed and arranged in the cable path could solve the problem.

    [0069] PREFERRED EMBODIMENT OF THE INVENTION
    [0070]
    [0071] First example
    [0072]
    [0073] Figs. 2a-2b and 3a-3b show different views of a vertical opening garage door (200) in which a device (1) according to the present invention has been installed where the different parts that comprise it are appreciated.
    [0074]
    [0075] Figs. 2nd and 3rd show the garage door (200) installed in the intersection line between a ramp (300) of descent to an underground garage and the horizontal floor (400) of the garage. A dashed line marks the plane of the threshold occupied by the door (200) when it is in its closed position. In this example, the door (200) is of vertical opening thanks to the actuation of a driving element (210) that moves vertically along a rail arranged on one or both sides of the threshold. A connecting rod (220) connects the drive element (210) with the door (200), so that when the drive element (210) is in a lower position, as shown in Figs. 2nd and 3rd, the mechanism forces the door (200) to adopt an elevated horizontal position, thus allowing passage for the entry or exit of a vehicle (100). When the driving element (210) moves upwards, the mechanism generates a combined movement of translation and rotation of the door (200) which causes it to descend until it adopts its closing position, as shown in Figs.
    [0076] 2b and 3b. A spring (230) prevents the door (200) from descending too quickly to its closed position.
    [0077]
    [0078] The device (1) of the present invention takes advantage of the movements of the driving element (210) to achieve the placement and collection of platforms (2) that reduce the change of slope between the ramp (300) and the horizontal floor (400) of the garage. The platforms (2) have a square or rectangular plate shape and are joined by a plate (5) so that they are coplanar with each other. Thus, the assembly formed by the platforms (2) and the plate (5) constitutes a single piece. The plate (5) has a width similar to the garage door (200), so that its ends are in a position close to the sides of the door (200) when it is closed. In addition, the platforms (2) are connected to the horizontal floor (400) of the garage by means of joints (3). For example, the joints (3) can be simple hinges bolted to the floor (400) of the garage. Therefore, the assembly formed by platforms (2) and plate (5) can rotate around the joints (3) between a lower position in which the end of the platforms (2) opposite the joints (3) is supported by the ramp (300), and a superior position in which the platforms (2) They are in an essentially vertical position.
    [0079]
    [0080] The displacement of the platforms (2) between the lower and upper positions is made thanks to a cable (4) that connects them with the drive element (210). Specifically, the cable (4) has a first end (41) attached to a point belonging to the assembly formed by platforms (2) and plate (5), in this case to the plate (5), and a second end (41) attached to the driving element (210). This connection must be made so that the cable (4) ascends when the door (200) closes and descends when the door (200) opens. In this specific case, since the drive element (210) ascends to close the door and descends to open it, simply connect the cable (4) directly to the drive element (210). In this example, two cables (4) are used, one on each side of the plate (5) connecting between platforms (2). Thus, when the door (200) is closed, the drive element (210) rises, the cable (4) is tensioned and pulls the platforms (2) causing them to rotate around the joint (3). The end result, once the door is closed, is that the platforms (2) remain in an approximately vertical position inside the garage, for example, resting on the door (200) of the closed garage. When the door (200) opens, the element (210) descends and the weight of the assembly formed by the platforms (2) and the plate (5) causes them to descend to the lower position.
    [0081]
    [0082] Second example
    [0083]
    [0084] Figs. 4a and 4b show a second example where the device (1) of the invention has been installed in a horizontal opening garage door (200). The threshold of the garage door (200) has also been marked with dashed lines, and is located just in the plane of the line of intersection between the ramp (300) and the horizontal floor (400) of the garage. In this case, the driving element (210) is an electric motor provided with a gear that meshes with a horizontal rack (not shown) arranged in the garage door (200). Therefore, it is not possible to directly connect the second end (42) of the cable (4) to the drive element (210), since this would not generate a vertical movement.
    [0085]
    [0086] To solve this problem, in this example some pulleys (6, 7) are arranged that transmit the movement of the door (200) to the first end (41) of the cable. Specifically, the second end (42) of the cable (4) is connected to a corner of the door (200) so that the opening movement of the door (200) causes a horizontal displacement of said second end (42) of the cable (4). The cable (4) is guided from this second end (42) through a first pulley (6) located above a corner of the door threshold (200) and of a second pulley (7) arranged above the opposite corner of the door threshold (200) until reaching the first end (41) of the cable (4) fixed to one end of a plate (5) connected in solidarity with the platform (two). In this example, a single platform (2) formed by a rectangular flat plate to which the plate (5) that extends laterally the entire width of the garage door (200) is used is used. The second pulley (7) is located vertically above the position of the end of the plate (5) to which the first end (41) of the cable (4) is fixed.
    [0087]
    [0088] Thus, when the door (200) is open as shown in Fig. 4a, the junction point between the second end (42) of the cable (4) and the door (200) is in its closest position to the first pulley (6). In this situation, the length of the cable portion (4) between said first pulley (6) and the end of the plate (5) is maximum, and therefore the first end (41) of the cable (4) has decreased from so that the platform's own weight (2) causes it to fall to its lower position. A vehicle (100) may in this situation enter or exit the garage. When the door is closed, the drive element (210) is activated to move the door (200) and, as a consequence, the junction point between the second end (42) of the cable (4) and the door (200) moves towards its farthest position to the first pulley (6). In this situation, the length of the cable portion (4) between the first pulley (6) and the end of the plate (5) is minimal, and therefore the first end (41) of the cable (4) ascends in the direction to the second pulley (7) dragging the plate (5). As a consequence, driven by upward displacement of the plate (5), the platform (2) rotates around the joint (3) until it adopts an essentially vertical position when the door (200) is completely closed.
    [0089]
    [0090] In this type of doors it may be necessary to cause a rapid ascent of the platform (2) at the beginning of the door closing process (200), since otherwise it could interfere with its closing. For this, although it is not shown in these figures, a cam or spring-type element coupled to the cable (4) could be installed in its path between the door anchor points (200) and the pulleys (6, 7). Any of these solutions (cam, spring or others) would cause a rapid movement of the cable (4) at the beginning of the door closing process (200) in order to accelerate the lifting of the platform (2), subsequently slowing the movement of the cable (4) once the door (200) has exceeded the position of the relevant edge of the platform (2).
