Abstract

Positioning for elements (12a, 12b) for horizontal section doors, wherein the horizontal elements (12a), or portions thereof, include an upright (14) for every head. The uprights (14) have a length slightly more than the height of the horizontal element (12) and have supporting means at the ends so that already during the assembly step only the contiguous uprights (14) rest on each other. <IMAGE>

Description

FIELD OF THE INVENTION

The present invention concerns doors made up of elements in horizontal sections which, in the closed position, are on the vertical plane and, in the open position, are normally on the horizontal plane above the transoit space.
To be more exact, the present invention concerns positioning means for said elements when they are with respect to their plane on the vertical plane.

BACKGROUND OF THE INVENTION

There are known doors with a single element and doors in which every element only rests on another, e.g. in EP 0 846 833 A2 .
The problems of centering and reciprocal positioning of the elements which make up said doors are known.
The problems of assembling and using the pedestrian doors which are made on the front plane of said doors are also known.
It is known that these elements can move one with respect to the other, and thus force the hinges.
The problems of assembly which oblige the elements to be stacked are known, with the consequent problem that the packings are crushed.
The aesthetic problems deriving from lateral displacements, even small ones, of one element with respect to another element, contiguous thereto, are also known.
The problems of air and/or light passing between one horizontal element and the other are also known.
The Applicant has devised, tested and embodied the present invention to solve the known problems.

SUMMARY OF THE INVENTION

The present invention is characterized in the main claim, while the dependent claims describe variants of the invention.
According to the invention, at the extremities of the horizontal elements there are uprights which cover the heads.
The invention can also be applied to doors for pedestrians to pass, such as are made in the front surface of said doors. In this case the invention can be applied both to the edges of the door-post and also to the edges of the pedestrian door.
There is one upright if the horizontal element is single or double, and there are two uprights if the horizontal element is double since there is a relation between the number of uprights and the type of horizontal element used.
Said uprights also perform the function of closing the extremities of the element and/or the elements'.
In the terminal parts of said uprights there are supporting means which function as reciprocal supporting elements at the ends of the horizontal elements.
According to a variant, said supporting means are of the block type.
Said blocks are advantageously made of plastic and advantageously are of the replaceable type because of the problems of wear.
According to another variant, said blocks have male-female centering means, which thus perform reciprocal positioning functions.
According to another variant, they are shaped, on the side of reciprocal rotation of the horizontal elements, in order to avoid interferences and to be able to contain the hinge body.
With the present invention, the horizontal elements rest one against the other on said blocks during the assembly step, and hence in their working position, so that the reciprocal profile, male-female, of the two contiguous horizontal elements is not in contact.
As a consequence, possible packings are not crushed and can work in the best conditions and thus last longer in time.
There is a further application of the invention when the doors consist of double elements associated together, such as for example an inner wall and an outer wall.
In such doors, the two horizontal elements which make up the vertical wall, according to the present invention, are at a different height.
Said different height, on the uprights and in the closed position, is compensated by the supporting means which allow to eliminate the passage of air and/or light.
As explained, according to another application of the present invention, the blocks, male and female, have an equally inclined part.
This inclination allows the blocks, during the opening and closing steps of the door, not to interfere with the rotation of the elements of the door itself and/or to at least partly house the hinge.

BRIEF DESCRIPTION OF THE DRAWINGS

These characteristics and advantages of the invention will become apparent from the following description of a preferential embodiment, given as a non-restrictive example with reference to the attached drawings wherein:

figs. 1a and 1b show an assembly in the terminal position of a door with double horizontal elements;
fig. 2 shows an assembly in an intermediate position for example in cooperation between the door-post and the pedestrian door;
fig. 3 shows the blocks as in figs. 1 and 2;
fig. 4 shows a detail of the present invention.

DETAILED DESCRITION OF THE PREFERENTIAL EMBODIMENT OF THE INVENTION

The attached figures show the solution of replaceable blocks cooperating with uprights which, in this case, are tubular.
The upper horizontal element 12a cooperates by means of hinges 13 with the lower horizontal element 12b.
At the ends (fig. 1a) or in an intermediate position (fig. 2) said elements 12 have uprights 14 in, this case two in number, cooperating with each other at different heights.
In the case of the figures, the uprights 14 are therefore two in number and are supported (14a, 14b).
The uprights 14 are made solid to the elements 12 in conventional manner. At the ends of the uprights 14 there are the blocks 15 and 16 which, in this case, are male 15a and 15b and female 16a and 16b.
Said blocks 15 and 16 have respectively male 17 and female 18 impressions which cooperate with each other, thus guaranteeing that the support is centered and correct.
The geometric conformation of the block 15 and 16 is affected by the section of the relative upright 14 and by the conformation of the horizontal element 12, in the zone of reciprocal cooperation block-element. The blocks 15 and 16 have a surface of reciprocal support 19, which can extend also to the impressions 17 and 18.
In the part behind the supporting surface 19, in this case, the blocks 15 and 16 have insertion means 20 by which they are inserted into the uprights 14.
According to the example shown here, the insertion means 20 provide positioning correction means 21 which facilitate assembly and guarantee correct positioning.
With the present invention, the parts in reciprocal cooperation between the contiguous horizontal elements 12 no longer touch each other, not even in the assembly step.
In the case of mountable blocks 15 and 16, they cooperate with the leading supporting surfaces of the uprights 14 and possibly also of the horizontal elements 12.
Finally, fig. 4 shows how the male 15 and female 16 blocks, in the closed position, can accommodate a corresponding hinge 13, walls 22a and 22b being provided with a suitable degree of inclination.
Said walls 22a and 22b of the respective male 15 and female 16 blocks, in fact, in the closed position create a seating able to contain the hinge 13 without interfering in the rotation of the panels through the positions from closed to open and vice versa.
