    DESCRIPTION
    Double canvas door.
    Object of the invention.
    The object of the present invention is a double tarpaulin door, which presents constructive particularities oriented to simplify its operation and to increase the tightness of the chamber formed by both canvases in the closing position of the door.
    Field of application of the invention.
    This invention is applicable in the field dedicated to the manufacture of doors, and in particular of insulating doors.
    State of the art.
    Currently, the doors are provided with two closing canvases, mounted on vertical guides and fixed by their upper ends to two motorized drums that turn in one direction or another cause the winding and unwinding of the respective canvases and consequently the opening and closing of the door.
    In the door closing position, the two canvases define an intermediate chamber.
    The intermediate chamber provides thermal insulation between the two zones separated by the door; being also known the incorporation in this type of doors of a heating group for the supply of tempered air to the intermediate chamber.

    A door of this type is described, for example, in the utility model ES 1 110 857 U.
    A general inconvenience in this type of doors is the constructive complexity and the costs determined by the use of two winding drums and the necessary means for their motorization. These motorization means may consist of two motors, one for each drum, or a single motor and a transmission for the simultaneous operation of the two drums, as is the case of the aforementioned ES 1 110 857 U.
    The use of two winding drums, poses a problem of sealing of the intermediate chamber, when the door is closed. Although the winding drums are housed in a hood or upper cover, the closure of said intermediate chamber at its upper end is practically unfeasible and provides significant leaks of the tempered air supplied to the interior thereof.
    The applicant of the present invention is unaware of the existence of a background that satisfactorily solves the problems raised.
    Description of the invention
    The double canvas door object of the invention has constructive characteristics that allow solving the exposed problem, significantly simplifying the simultaneous operation of the two canvases of the door and providing a superior closure of the intermediate chamber, which substantially improves its insulation in the closing position
    To achieve the proposed objectives, a double canvas door has been developed, comprising a single drum for simultaneous winding of both canvases and a single drive motor, which greatly simplifies the construction and costs of the door.

    The upper ends of the canvases are connected to each other and with a hitch tape to the winding drum, establishing said joint at the upper end of the intermediate chamber a closure that helps keep the temperature and atmospheric conditions in its interior stable when The door is closed.
    In an embodiment of the invention for establishing said joint, the door comprises a joint profile with several parallel passages for securing the upper end of the two canvases and a first end of the hitch tape.
    On the other hand, the winding tack comprises a first longitudinal lace for the attachment of the hitch tape and a second longitudinal lace in which the joint profile is housed, so that in the winding position of the canvases the union between the tarpaulins and the hitch tape does not protrude from the general contour of said winding drum and that the coupling between the joint profile and the second socket collaborates in the canvas tension support.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:
    - Figure 1 shows a front elevation view of an example of embodiment of the double canvas door according to the invention, in the closed position.
    - Figure 2 shows a profile view of the double canvas door of the previous figure sectioned by a vertical plane and an enlarged detail of an upper portion thereof.
    - Figure 3 shows a top plan view of the double canvas door of Figure 1 sectioned by a horizontal plane

    - Figure 4 shows an enlarged profile view of an upper portion of the door in which the canvases have been shown in the opening position, and an enlarged detail of the drum in which the joint profile of the canvases can be seen with the hitch tape, housed in the second longitudinal shaft socket.
    Preferred embodiment of the invention.
    As can be seen in figures 1 to 3, this double canvas door comprises a frame (1) provided on each of its sides with a pair of guides (2a, 2b) for the circulation of two tarpaulins (3a, 3b) that have at its lower end of tension weights (31) and whose upper ends are connected by means of a joint profile (4) to a hitch belt (5) in a single winding drum (6) driven by a drive group (61) ) so that when the winding drum is rotated in one direction or another, simultaneous winding or unwinding of the two canvases (3a, 3b) in the drum (6) takes place and consequently the opening or closing of the door. The upper area of the door is provided with a cover (7).
    As can be seen in Figures 2 and 3 tarpaulins (3a, 3b) define between each other an intermediate chamber (8) that laterally has blow nozzles (9) connected by ducts (91) to a heating group (10) responsible for introducing tempered air into said intermediate cavity.
    As can be seen in the enlarged detail of Figure 2 and Figure 4, the door comprises between the upper end of the guides (2a, 2b) a centering profile (11) of the canvases (3a, 3b).
    As can be seen in the details of figures 2 and 4, the joint profile (3), in this case with a substantially triangular general section, has on one of its faces several parallel passages (41) for securing the upper end of the two tarpaulins (3a, 3b) and a first end of the hitch tape (5).
    In this exemplary embodiment, the fastening of the canvases (3a, 3b) and of the coupling tape (5) with respect to the joint profile is carried out in a known manner by introducing in the passages (41) of some regrindings defined in the tarpaulins (3a, 3b) and on the hook tape (5) by means of respective hooks. 5
    The winding drum comprises a first longitudinal socket (62) for securing a second end of the hitch tape (5), and a second longitudinal socket (63) in which the joint profile (4) is housed when It produces the winding of the canvases (3a, 3b) on the drum (6) as can be seen in Figure 4.
    In this winding position the joining profile (4) and the joining areas thereof with the canvases (3a, 3b) and with the hitching tape (5) are entered with respect to the general cylindrical surface of the winding drum avoiding regruesamientos 15 that could cause marks or deformations on the canvas (3a, 3b).
    As can be seen in the detail of figure 2, the union of the upper end of the canvases (3a, 3b) with the union profile (4) establishes an upper closure of the intermediate chamber (8) of the door which contributes to maintaining the conditions of temperature existing in the atmosphere of said intermediate chamber (8).
    Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and disposition of the elements described may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
