Abstract
Description
- The present invention relates to an inwardly opening tilting door with a new double elevation system and more particularly to a door of the type designed to close the entrances to garages and similar premises in which the door tilts from a vertical closed position into an upper horizontal open position, and is provided with a structure and means which enable it to be maintained stably in these two limit positions, and having the particular characteristic that the door opens inwardly without guide tracks leading to the ceiling and using a spring compensated system by means of which no space is lost, the door does not obstruct the street and, since it has lateral arms, it does not wobble as in the case of other sprung doors.
- Counter-balanced tilting doors used for the entrances of certain premises such as garages and the like are in some cases provided with two hinged parts which, in the closed position, are arranged vertically one above the other thereby closing the entrance, whilst in the open position these two parts of the door fold on each other such that a quarter of the door projects outside.
- In other cases the door consists of a single piece and tilts from a vertical closed position into an upper horizontal open position.
- In the first case, in which the tilting door consists of two hinged parts, said parts suffer from the drawback that in the open position they partially protrude outwards, and because of the current requirement that the outermost edge of the tilting doors of garages and the like should be in line with the innermost part of the pavement, this means that the entrance to the premises or garage fitted with this type of door must be set back so that the door never protrudes beyond the limits established by current requirements, i.e. such that the projecting part does obstruct the pavement where pedestrians pass.
- In the second case, i.e. tilting doors with springs consisting of a single piece and with no guide tracks leading to the ceiling, again the door protrudes partially outwards due to the assembly mechanism and its somewhat irrational elements, suffering from the same drawbacks as those mentioned above, and with the further drawback that since the door opens outwardly it also obstructs the street whilst it is being opened.
- The door proposed by the present invention has been designed to solve the problem described above in a simple, efficient and fully satisfactory way, said door being constituted such that in the closed position it is perfectly co-planar with the frame in which it is mounted, whilst in the open position it is situated in a horizontal upper position and is set back inside the premises, without the use of aesthetically undesirable guide tracks leading to the ceiling, such that a car can approach the door without said door obstructing the street as it is opened.
- More particularly, the door of the invention is mounted between a pair of lateral arms and wheels which slide along lateral guides designed for the purpose, said door being held by said lateral arms and rollers, which only allow it to move so as to open and close the door, i.e. up and down, thereby preventing wobbling and other irregular movements.
- A pulling spring is situated between each of the two main arms which comprise the lateral structure and the corresponding upper corner of the frame, in such a way that when the operator pushes the door towards the open position, and said door is no longer vertical, said springs tend to push the door constantly towards said open position, another spring being positioned between the same upper corner, provided on each side, and a lever attached to a lug joined to the upper arm, said spring acting only when the door nears the fully raised position in which the lever attached to said spring moves from a position which constitutes a continuation of the lug on which it pivots into a position perpendicular thereto.
- As the door is tilted from one position to another it is guided by means of wheels and said lateral arms which, together which the double spring elevation system, prevent it from pitching and wobbling as it is raised or lowered, as is the case with other types of sprung door.
- If, due to some assembly error, the door is not properly squared relative to the frame, it is provided with adjusting means consisting of a movable element, on which is mounted the roller or wheel of each of the sliding sides of the door (said roller or wheel constituting the weight stop of the door), together with an element for securing the guide loop of the main arm, thereby making it possible to adjust the general structure of the door relative to the corresponding frame both laterally and horizontally.
- By means of its studied geometry and as a safety system, the door remains open if one or even all four of its springs are removed with no danger of it becoming disengaged and causing an accident.
- As has been said above, in the open and closed limit positions the door remains stable as a result of the above mentioned springs, since in the closed position, even though the springs are pulling the door, said door is vertical and therefore they tend only to lift it, rather than to make it tilt, such that it remains perfectly immobile in said closed position, whilst in the open position it also remains stable since the springs which are attached to the two arms of each side always act so as to make the main arm push the upper arm, tending to keep the door in said horizontal open position.
- In order that the present invention be better understood, the accompanying drawings show by way of nonlimiting example one practical embodiment of the invention.
- In said drawings:
- Figure 1 is a lateral elevation view of the swinging door in the open position with all of the elements or mechanisms which form part of it.
- Figure 2 is a lateral elevation view, as in the previous figure, with the door in an intermediate closed position.
- Figure 3 is a lateral elevation view, i.e. similar to the previous figures, with the door completely closed and hidden within the general structure of the corresponding frame.
- Finally, figure 4 is a rear elevation of the door in the closed position.
- As can be seen in the figures, the door of the invention is designed to be mounted in the entrance or opening of a premises such as a garage or the like, said entrance or opening being fitted with a corresponding frame 1 on each of whose lateral or vertical columns are fixed corresponding
shapes 2 with a U-shaped cross section such that their open faces are opposed. - The
door 3 is held between a pair of upper,lateral arms 4 and number ofsupport rollers 5 which slide along theshapes 2. In other words, thedoor 3 is provided on its lower edge, when in the closed position, with a number oflateral rollers 5 which slide along theshapes 2 joined to the frame 1, saidrollers 5 being removably mounted oncorresponding elements 6 which, as can be seen in figure 1, are provided with elongated holes for adjusting the position of therollers 5 so that, if necessary, the general structure of the door with all of its mechanisms can be levelled within the frame 1. -
Supports 7 are provided at each of the upper corners of the frame 1, one end of said supports constituting pivoting means for the lateral andupper arms 4, saidsupports 7 being provided with transverse axes orrollers 8 for joining or pivoting astrap 9 to which is fixed aspring 10 whose opposite end pivots on alever 11 which in turn pivots on atab 12 that emerges from thedoor 3 itself and on which in turn pivots the other end of thearm 4. - In other words, the
door 3 is mounted between thelateral arms 4 and the sliding guide rollers orwheels 5 which slide vertically along the lateralvertical shapes 2. - A
second arm 14, referred to as the main arm, pivots at apoint 13 on thearm 4, closer to the end which pivots on thesupport 7 than the end which pivots on thedoor 3, the opposite end of saidsecond arm 14 sliding in and being guided by a kind ofloop 15, saidloop 15 also being removably or adjustably joined to anelement 16 again provided with elongated holes so that saidloop 15 can be fitted at different heights, with the particular characteristic that in the fully raised position the sliding action of saidmain arm 14 is prevented from continuing by means of astop 17 provided at the end thereof, said stop preventing thearm 14 from coming out of theloop 15 by acting as a stop against it and thereby preventing the entire door mechanism or assembly from collapsing. - The
main arm 14 is also attached to aspring 18 which pivots between atab 19 fixed to thearm 14 itself and theupper support 7 of each corner, being further provided with aroller 20 made of nylon or the like on which runs thestrap 21 or metal band to which thespring 18 is attached. In other words, both of thesprings straps - According to the structure described, the operation of the door of the invention is as follows:
- When the door is in the closed position, i.e. positioned vertically or hidden within the frame 1, or rather the
shape 2 joined to said frame, saiddoor 3 need only be pushed gently in the centre for it to start moving upwards along theguides 2 with the help of thespring 18, such that when the door nears the fully raised position, thespring 10 begins to act such that once thedoor 3 is horizontal it keeps it in the open position, said door being prevented from moving downwards by the action of saidspring 10 and of course thespring 18 that pulls thearm 14, saidarm 14 tending to push thearm 4 upwards and as a result making it impossible for thedoor 3 to close accidentally. - To close the
door 3 starting from this open position it has to be pushed or pulled to cause thewheels 5 to start sliding downwards along theguides 2, since thesprings door 3 reaches the vertical or closed position at which point, since the springs are vertical, their pulling action cannot cause the door to tilt unless said opening action is initiated once again in order to open thedoor 3. - The present description is considered to be more than sufficient for any expert in the field to understand the scope of the invention and the advantages which it provides.
- The shapes, sizes and arrangement of the elements of which the invention consists, as well as the materials of which they are made, are independent of the object of the invention providing they do not affect its basic concept.
- The terms used should be considered in a general and non-limiting sense.
