Description

Quick opening door perfected.

Object of the invention

The present invention relates to a quick opening door perfected, of the kind that include a perimeter frame and a flexible closing sheet that is related by its upper end with a winding shaft and that has in its sides of some stops for the sliding assembly and with possibility extraction in flexible guides housed in the uprights door verticals.

Background of the invention

Currently, doors are widely known in the market denominated of fast opening and that have a sheet of closure that coils or unwinds on a motorized shaft, arranged in the upper area of the frame, to perform the opening and closing from the door opening.

It is also common for these flexible sheets to have in their sides of protruding stops that slide over ones flexible guides housed in the vertical uprights of the door and that can be released from such flexible guides in the event that the Door receives a frontal impact.

In the doors on the market the flexible sheet usually has a crossbar in its lower area, generally composed of a bar or metal plate, housed in a defined longitudinal passage at the lower end of the sheet. This profile acts as a counterweight, to facilitate the lowering of the sheet, and stiffening element, to maintain the lower end of the blade in extended position.

The problem that usually occurs in these types of doors is that when said metal profile receives an impact important, for example when being dressed by a wheelbarrow, suffers permanent deformation, which can prevent correct operation of the door by reducing the useful width of the sheet due to the curvature of said lower profile.

Therefore, the technical problem that arises is the development of a quick opening door in which the means arranged in the lower area of the flexible sheet to act as a counterweight and contact element with the ground, can not suffer a deformation permanent in the case of frontal impact, regardless of the intensity of this one.

Description of the invention

The perfected quick opening door object of this invention presents constructive particularities oriented to solve the exposed problem and more specifically to have in the lower end of the closure sheet of means that allow to act as a counterweight and that can be elastically deformed before possible impacts ensuring that the lower edge of the sheet return to the initial straight position, after curving to cause of impact

For this and according to the invention, the door comprises two longitudinal pieces of flexible material fixed on the opposite sides of the closure sheet and in correspondence with its lower end, and a longitudinal profile also made of material flexible designed to be fixed on the lower end of the sheet of closing.

Said longitudinal profile has two fins in its upper area Longitudinal opposed as a clamp, oriented vertically, for the accommodation of the longitudinal pieces Solidarity to the closing sheet. Said longitudinal profile has in its intermediate zone at least one longitudinal hole in which are housed several sections of rigid bar, which they act as counterweight, allowing elastic deformation of the flexible profile for those areas between successive rigid bar sections.

The aforementioned longitudinal profile also presents, in its area bottom, a longitudinally oriented tubular configuration and a longitudinal fin oriented towards the lower zone, forming both, in the door closing position, the zones of contact of the flexible profile against the ground.

To mount this flexible profile on the area lower of the closing sheet, it is expected that both longitudinal pieces fixed to the sheet, such as fins upper flexible profile, present on surfaces facing some regruesamientos and some complementary recesses intended to fit, establishing profile retention flexible in the mounting position with respect to the sheet closing.

It is also planned that the tubular configuration and the fin longitudinal, defined in the lower area of the flexible profile, have a material thickness less than the rest of the profile, providing them with the elasticity necessary to provide a soft closing of the door when contacting against the ground.

Description of the figures

To complement the description that is being made and with in order to facilitate the understanding of the characteristics of the invention, a game is attached to the present specification of drawings in which, for illustrative and non-limiting purposes, has represented the following:

- Figure 1 shows a schematic front elevation view of the perfected rapid opening door object of the invention.

- Figure 2 shows a profile view of the lower end of the sheet on which the longitudinal pieces can be observed fixed to that and the longitudinal carrier profile of the sections of rigid bar intended to act as counterweight.

- Figure 3 shows a partial elevation view of the profile lower sectioned by its medium vertical plane, being able to observe the rigid bar sections housed in one of the longitudinal holes of said profile.

Preferred Embodiment of the Invention

As can be seen in the referenced figures, the door of perfected rapid opening object of this invention comprises a perimeter frame (1) and a flexible closing sheet (2) fixed by its upper end to an axis (3) which, when turning in one or the other felt by the motor action (4), causes the winding and unwind of the sheet (2) and consequently the opening and door closing.

The sheet (2) has lateral stops laterally (21) for guiding them in flexible guides (11) arranged vertically inside the vertical uprights of the frame (1), so that when receiving a frontal impact the stops (21) can be released from the flexible guides (11).

The flexible sheet has at its lower end, as is you can see in figure 2, two longitudinal pieces (22), of `` L '' section, fixed on opposite sides of that.

On the aforementioned longitudinal pieces (22) is mounted a lower profile (5), of flexible material, which defines in its upper end two fins (51) as a clamp and having on the opposite sides of two recesses (52) intended for receive inside the prominent areas of the pieces Longitudinal (22).

The mentioned profile (5) also has holes longitudinal (53, 54 and 55) that allow accommodation in your inside of counterweights (6) composed of sections (61, 62) rigid bar, longitudinally aligned inside one of said holes.

The discontinuous nature of the counterweight (6) allows the profile (5) can deform laterally upon receiving a frontal impact and return to the starting position again, due to the character flexible and discontinuity of those mentioned counterweights (6).

Below, the longitudinal profile (5) has a tubular configuration (56) and a vertical fin (57) that make up the contact areas of said profile (5) with the ground at place the flexible sheet (2) in the closed position of the door.

As can be seen in Figure 2, the fin (57) and the tubular configuration (56) have a lower material thickness than the rest of the profile to facilitate deformation when contacting with the floor and make a smooth and effective closure of the door.

Once the nature of the invention has been sufficiently described, as well as an example of preferred embodiment, it is stated the appropriate effects that the materials, shape, size and disposition of the described elements may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.
