Description

Chassis with sliding roof panel.

The present invention relates to a chassis with sliding roof panel or similar, intended in particular although not exclusively, to make an exutory to escape from smoke

Numerous are already known in the art embodiments of such a device, which comprise in particular a swing designed to release or close a step in the roof and generally comprising a flat panel that allows, in opening position, the evacuation of fumes or others, from the interior of a room located under this roof towards the atmosphere outside, above this one.

In particular, when the swing is supported by a fixed sleeper, solidary of the roof and surrounding the passage, the opening can be obtained by lifting this swing to the way of a bellows with the help of a cat or a means of command analog, which exerts an upward push on the edge or bottom crossbar of the panel, the other cross being on its side articulated upper on the edge of the sleeper.

This solution is impractical and leads in particular to make the roof panel go outwards in the opening position of the passage, so that it is then subjected to the wind that can exert an effort on it prohibitive. In addition, in such a device, it is necessary to keep the panel in this position, associate some strips sliders or others that accompany your swing around the planned joint on the sleeper, these strips being a relatively complex embodiment and presenting a certain fragility.

Another classic solution is to mount the panel of the swing over the passage delimited by the fixed frame of the sleeper, so that you can slide in your plane over some guides or guiding means analogous, solidary of this sleeper and parallel to the slope of the roof, releasing or, on the contrary, shutting this step.

In this case, the panel moves over the step, preferably also under the effect of a cat that exercises its push on this panel in its plane and from below to above.

This second solution has the advantage, with with respect to a set with opening type bellows type above, not to take the panel on the roof and avoid wind effects on it. However, it presents Also inconvenient.

In said embodiment, in effect, the opening is always perform pushing the sliding panel with respect to the sleeper fixed, from the bottom up, this because of the obligations of tightness imposed on the chassis due to the slope of the roof and the need to provide, on the edge or crossbar top of the panel, a flange or an analogous sleeve, with an organ sealing which, in the closed position of the panel, clears the game that necessarily exists between the fixed frame of the sleeper and the mobile panel, so as to avoid water infiltration of rain flowing over the roof.

However, such a shift towards above to make the opening of the passage, requires that the cat command can overcome the relatively important resistance opposite by this panel due to its weight that can be accentuated depending on of the slope, which needs a remarkable dimensioning of this cat and increases its cost, especially if this cat must maintain the step open and the panel pushed accordingly for a period of time high time, in order to allow a satisfactory evacuation of the fumes outwards.

In addition, it is necessary in this solution, to equip the fixed sleeper and mobile panel with an old-fashioned system for that, in case of unexpected and sudden failure of the cat, the panel previously open don't be brutally dragged in the direction inverse, from top to bottom on its guides under the effect of its own weight, which may be the origin of an accident with respect to a person who has a part of his body inserted into the passage opening.

Here too, the cost of the set can be seriously taxed by the use of said system which also, according to the dimensions of the sleeper and the slope of the roof, can require the use of media that form above the roof, which makes the whole aesthetic. The DE document 86,067,890 presents another solution.

The present invention is related to a chassis with Sliding opening that stands out from this second solution, with the swing panel that releases or closes the step in the sleeper sliding with respect to it according to the slope of the roof, but that avoids the aforementioned inconveniences.

To this end, the considered chassis, which includes, on the one hand, a fixed sleeper, to be solidary of the roof of a building and to laterally delimit a step planned in it, in particular to allow the escape of fumes from inside the premises arranged under the roof towards the outside atmosphere and, by another part, a swing formed by a panel to slide in its plane with respect to the sleeper, according to a direction in parallel to the slope of the roof above the step to perform, according to the relative position of this panel, its opening or closing, comprises this sliding panel of the swing, which is made by means of two identical semi-elements that, in the closed position of the passage, they are coupled to each other in a medium plane transverse that separates the passage into two equal parts and that are separated from each other in equal and opposite distances with with respect to that plane when the opening of this step takes place, and this chassis comprising means that ensure that displacements of the two half elements of the panel are permanently conjugated and are symmetrical in two directions of opposite senses.

Preferably, the displacements of the two Semi-elements of the sliding swing panel are made by middle of a cat or analog.

In a particular embodiment of the chassis considered, the sleeper understands, to delimit the passage in the roof, a rectangular frame, with two side faces verticals that extend according to the slope of the roof, and others two extreme faces also vertical, perpendicular to the faces lateral, comprising the sleeper according to at least and preferably its two side faces, outside the passage, fixed guide rollers, which cooperate with guides solidarity respectively of the two half-elements of the panel sliding of the swing, extending these guides parallel to The slope of the roof.

According to a complementary characteristic, the guides of the two semi-elements comprise each one zipper geared with a common forwarding pinion, arranged between the guides and whose axis is supported by the sleeper's side face, ensuring this pinion in synchronism the displacements in senses  inverses of the two semi-elements with respect to the sleeper.

According to another characteristic, the solidarity guides of the two half elements of the sliding panel of the swing are superimposed, the zippers of their guides arranged faced and separated by a vertical distance equal to diameter of the transmission pinion supported by one of the faces Sleeper sides.

Advantageously, each of the two semi-elements the sliding panel of the swing is flat and includes a return vertical that extends parallel to the side face of the frame and that supports the guide of this semi-element.

According to yet another feature, the plates that they form the two semi-elements of the sliding panel present about rushes that ensure a mutual coating of these plates in the vertical of the transverse middle plane that separates the passage in two equal parts.

Preferably, the reeds have some together to make the sealing of the two semi-elements when they are coupled in the mid-transverse plane.

Other features of a chassis with opening sliding, made according to the invention, will appear at through the following description of an embodiment example, given for indicative and non-limiting purposes, with reference to annexed plans in which:

- Fig. 1 schematically illustrates a panel sliding, of a type known in the art.

- Fig. 2 is a perspective view of a chassis, with sliding opening, made in accordance with the invention.

- Figs. 3 and 4 are schematic views to greater scale, in cross section, showing the two half elements of the sliding panel of the swing, respectively in the position of opening and closing of the passage.

- Figs. 5 and 6 are analogous views of Schemes of Figs. 3 and 4, which require in greater detail the structure of the means used in the embodiment considered.

In Fig. 1, reference 1 designates in its set a sliding opening chassis of a type known per se in the art, which comprises a fixed sleeper 2 intended to be mounted on a roof 3 that has a given slope, whose value is indifferent to the invention, delimiting this sleeper a step 4 of substantially rectangular shape practiced in the roof in order to allow evacuation through this step of similar fumes or vapors, from inside a room located under roof to the outside atmosphere.

Sleeper 2 extends around step 4 and it has a vertical flange 5 integral with a base 6 supported on roof 3, and is open to the outside and inside to Through this step.

On the flange 5 it is mounted on sliding a sliding panel 7, generally flat, comprising a framed 8 for a glazed central surface 9 but that it could be constituted differently and in particular be solid.

A control jack 10 allows to ensure the maneuver of the sliding panel 7 to make it pass from the bottom up, from a closed position in which you completely close step 4 a an opening position in which, conversely, it totally releases this one, allowing the fumes to escape through the roof 3. In the example shown, the cylinder 11 of the jack 10 is integral with the flange 5 of sleeper 2, while its stem 12 is fixed by a fixing point 13 on a crossbar of frame 8 of the panel 7, ensuring the actuation of this jack thus the sliding of the panel with respect to the sleeper in one direction or in the other, this slide being controlled by means of guided, in themselves classics, provided on the panel or in the sleeper and of which it is not necessary to expose here in detail its  realization.

Also, of course the drive jack of the sliding panel could be mounted differently, with its cylinder fixed on this panel and its rod immobilized on the sleeper, conversely to the previous assembly.

Said embodiment has the disadvantage that the sliding panel 7 exerts permanently on the jack 10, when it is in an extended position where it releases the passage 4, a permanent antagonistic effort due to its own weight and the slope of roof 3, which requires a large dimensioning of this  cat and therefore increases the cost of installation.

In addition, in case of brutal failure of the cat, it is of fear that the sliding panel 7 suddenly returns to its position initial, that is, in which you close step 4, in the manner of a guillotine, being able to cause an accident in the case of that an individual had introduced a part of his body into the opening of the passage, which requires, in such an embodiment, provide means of immobilization or at least braking of the panel in his career.

In addition, the location of the step practiced in a roof for the escape of the fumes, must be determined so that the opening thus created is located closest to the part highest roof, so that evacuation is as effective possible, with hot vapors or gases tending to accumulate in this part.

Now with a sliding panel 7 whose surface corresponds substantially to that of step 4, it is necessary foresee above the sleeper 2, on the roof, a space of sufficient displacement, such that the passage is in turn displaced down the corresponding distance, thus limiting its optimal location

Fig. 2 schematically illustrates a chassis of sliding opening, made in accordance with the invention, this chassis 2 comprising, as in the previous example, a sleeper 2 with a vertical flange 5 and a support base 6 on roof 3, which delimits step 4 to be sealed.

According to the invention, however, the panel sliding, here designated under reference 14 as a whole, is It consists of two semi-elements, respectively 15 and 16, which they each have the same surface and arranged in such a way that this surface corresponds substantially to that of the step 4, the two semi-elements 15 and 16 being also associated with means that allow you to synchronize your movements in the direction inverse of each other in such a way that, when they are totally separated, step 4 is entirely released, while, when these panels are in contact and coupled with each other according to an average plane that passes through the center of this step, schematized in 17 in the figure, and that separates it into two parts same, be completely sealed.

Figs. 3 and 4 represent, in section in particular according to the aforementioned midplane 17, the structure of sleeper 2 and sliding panel 14 according to the exemplary embodiment of Fig. 2.

In these figures the base 6 is again found which allows to fix the sleeper 2 on the roof 3, as well as the flange 5 of sleeper 2 delimiting step 4 through it. This step 4 presents two extreme vertical faces, respectively 18 and 19, and two lateral faces, also vertical and perpendicular to the extreme faces, appearing in these schemes only one of these side faces, designated by the reference 20. The four faces of flange 5 are made with the help of metal profiles 21, conveniently assembled together.

Also, the two semi-elements 15 and 16 that form the sliding panel 14 are constituted with the help of metal profiles 22, illustrating Fig. 3 these elements in opening position in which they release step 4 and Fig. 4 these same elements in closed position, step 4 being then fully sealed

Figs. 5 and 6 represent in more detail the particular structure of the various components of the chassis considered and in particular the means that are used to ensure the guidance of the two half elements of panel 14 in their displacements with respect to the sleeper 2.

Thus, the vertical and lateral faces 20 of the flange 5 of sleeper 2 present on its outer surfaces to step 4, guide rollers, respectively 23 and 24, mounted crazy on axes 25 and 26 supported by supports 27 and 28, in turn in solidarity with profile 21, these being supports preferably immobilized in grooves provided for this end in the facing wall of this profile.

These rollers 23 and 24 are arranged to engage in overlapping guides 29 and 30 according to the height of the flange 5 of sleeper 2, guide 29 being integral with semi-element 16 and guide 30 of semi-element 15 or vice versa, cooperating the rollers and guides mutually in such a way that the displacement of the two semi-elements on the flange 5 of the sleeper 2 above step 4, to open or close it, it effect always keeping them parallel to each other and parallel to the roof plane 3.

In addition, each side face 20 of the flange 5 Presents, housed between rollers 23 and 24, a forwarding pinion 31, which rotates freely on an axis 32 preferably located at the middle plane 17 of step 4, this pinion being arranged for Cooperate with two identical zippers, respectively 33 and 34, facing each other and to this end solidarity with guides 29 and 30 respectively, these zippers being accordingly phones with these guides and the two semi-elements 15 and 16 at which ones belong The distance that separates the two guides is by both substantially equal to the outer diameter of the pinion.

Under these conditions, it is easily understood that, under the effect of a means of command (not represented in the Figs. 5 and 6), but that can be in particular a cat of the type of illustrated under reference 10 in Fig. 1, the displacements of the two semi-elements 15 and 16 that constitute the panel slide 14, are carried out permanently causing a approach or an inverted distance from these semi-elements, which It is always synchronous and presents the same amplitude for the one and the other.

In the closing position of step 4, the two semi-elements 15 and 16 are coupled to each other in the middle plane 17 of this step and completely shut up this one. Advantageously, the profiles 22 that delimit these semi-elements may be provided with coating rushes 35 and 36, provided with gaskets 37, which ensure satisfactory tightness of the chassis in closing.

In the open position, the two semi-elements 15 and 16 progressively move away from each other, with some reverse movements relative to the sleeper, these displacements always being conjugated and symmetrical one at another from the middle plane 17.

The realization of said opening chassis Sliding has numerous advantages, among which it is convenient underline, first of all, the permanent balance that is secured between the two semi-elements, the weight of the lower semi-element always balanced by the semi-element superior that opens at the same time. It should be noted that the force necessary to make this opening, that is the separation symmetric and synchronous of the two semi-elements, it is practically null, whatever angle measures the slope of the roof.

So, the cat or another element of Two-part sliding panel drive can be very much less dimensioned than in classic solutions and causes widely less expensive.

In addition, the chassis design eliminates the need to mount any old-fashioned system. The same time, the means that allow guiding the guides and activating the zippers to keep the two semi-elements separated from each other other and leave open the passage through the roof, are much more Simple to conceive and perform.

On the other hand, the overflow of the panel sliding with respect to the sleeper, particularly upwards in the direction of the slope, being reduced by half, corresponding to that of only one of the two elements, it is possible arrange this step as close as possible to the roof ridge, which improves the efficiency of smoke evacuation through East.

Thus a conception device is realized simple and of great efficiency that, however, is not exclusively limited to the intended application. In particular, the same system or equivalent could be adopted to send the opening sliding panels for access to premises any, such as between the bridge and the cabin of a ship, or also to perform roof hinges ordinary.

Of course, the invention is not limited to the example more specially described and represented; it covers by the contrary all variants in the extension of the protection of The claims.
