Description

The enclosure frame provided with sheets

Frame for enclosures provided with sliding leaves. Object of the invention

The present invention presents a frame for enclosures provided with sliding sheets, of the type comprising two vertical uprights and two horizontal uprights, provided with parallel guides for mounting the sliding sheets and defining a longitudinal channel; presenting the longitudinal channel of the lower horizontal upright, in its outer section, lateral drainage holes made in the outer guide. Field of the Invention

This invention is applicable in the field dedicated to metalwork manufacturing. Background of the invention

The metal frames used in enclosures provided with sliding blades generally have two parallel guides, one inside and the other outside for mounting and sliding the sliding blades between the opening and closing positions; these guides defining each other a longitudinal channel.

It is known that the end length of the lower horizontal upright has lateral drainage holes, made in the outer guide, for the evacuation of water that could accumulate in said longitudinal channel.

More specifically, these lateral drainage holes are defined in that outer section of the longitudinal channel which remains visible and accessible from the outside of the enclosure when the sliding blades are arranged in the closed position.

The definition of these holes in the inner section of the outer guide is not feasible, since the wind would pass directly from the outside to the inside of the enclosure, preventing said enclosure from complying with the regulations and requirements related to watertightness against rain and wind.

In this type of enclosures, when the rain impacts on the outer face of the sliding sheets, the outer sheet directly pours the water towards the outside of the enclosure while the inner sheet pours the water on the longitudinal channel defined between the guides.

Although the sliding blades generally have means in the crossing area of means to prevent water from circulating towards the inner section of the longitudinal channel, the necessary assembly tolerances do not prevent the water accumulated in the longitudinal channel from passing into said inner section of the longitudinal channel .

In these cases, the water accumulated in the inner section of the longitudinal channel is visible from the interior of the house, the longitudinal channel being able to fill with water, and the water will flow to the inner side of the enclosure when heavy rains occur.

Therefore, the technical problem that is proposed is the development of a frame for enclosures provided with sliding leaves that allow to effectively evacuate the water that could access the inner section of the longitudinal channel, however avoiding the entry of air through the drainage holes and so that the enclosure can meet the necessary regulations and requirements that are related to the enclosure Against the water and the wind.

slides, object of this invention, being of the type of which comprise vertical uprights and horizontal uprights provided with parallel guides for mounting the sliding blades and defining each other a longitudinal channel; presenting the lower horizontal upright, in the outer section of the longitudinal channel, lateral drainage holes made in the outer guide; It has the particularity of incorporating constructive features oriented to allow an effective water drain that could access the inner section of the longitudinal channel, corresponding to the lower horizontal stile of the frame and that remains visible and accessible from the inside of the enclosure when the sliding blades are arranged in the closed position.

Another object of this invention is to prevent the wind from accessing the interior of the enclosure through the holes used to extract the water accumulated in the inner section of the longitudinal channel.

To this end, and according to the invention, the lower horizontal upright presents, below the longitudinal channel, a tubular chamber that extends to the Sargo thereof and which has, at least: an upper hole for access to the inner section of the longitudinal channel and a lateral opening for access to the outer side of the enclosure for the evacuation of the water accumulated in said inner section of the longitudinal channel.

Said tubular chamber comprises a siphon for the retention of water between the upper and lateral offices, and the formation of a barrier that prevents the passage of air to the interior of the enclosure through the above-mentioned and lateral drainage holes.

Said siphon is defined by a partition that extends from the upper wall of the tubular chamber to the lower area of the same lower end and is located below the level of the lateral hole outflow and above the lower wall of said tubular chamber, thereby ensuring the existence of a water barrier between the mentioned holes and that the wind water access the inner side of the enclosure through them.

Additionally, this frame comprises in the upper hole of the tubular chamber, which accesses the inner section of the intermediate channel, a unidirectional valve that allows the flow of fluid only into the lower tubular chamber, however preventing the passage of liquid or wind in the direction opposite.

This unidirectional valve constitutes an effective means to prevent the entry of air into the enclosure in the event that the water contained in the siphon has evaporated, which can happen in summer times due to evaporation. Description of the fi gures

As can be seen in Figure 1, the frame for enclosures provided with sliding sheets object of the invention comprises two vertical uprights (1,2) and two horizontal uprights (3, 4), upper and lower respectively, each provided with a pair of guides ( 5a, 5b) parallel, exterior and interior respectively, for the assembly of two sliding sheets (6a and 6b) as can be seen in Figures 3 and 4.

It should be mentioned that in the figures 2,3,3 the references "INT." And "EXT." Have been included to identify the inner and outer sides of the enclosure respectively.

In the lower horizontal upright (4) of the frame, the guides (5a and 5b) define each other a longitudinal channel (7) which, in the closing position of the sliding blades (6ay6b), has an outer section (7a), accessible and visible from the outside of the enclosure, and an inner section (7b), accessible and visible from the inside of the enclosure.

As you can see in fi gures 1 and 3, the outer guide (5a) presents, in correspondence with the outer section (7a) of the longitudinal channel (7), some holes (51) for the evacuation of the water towards the outside.

For the evacuation of the water that could access the inner section (7b) of the longitudinal channel (7), the lower horizontal post (4) has a tubular chamber (41) below the longitudinal channel (41) provided with upper holes (42) for access to the inner section (42). 7b) of the longitudinal channel, and of lateral holes (43) for access to the outside of the enclosure; said tubular chamber (41) comprising in its interior a partition (44) extending from the upper wall of said tubular chamber (41) towards the lower area and the lower end of which is located below the level of the lateral hole (43) and above the lower wall of said tubular chamber.

The said partition (44) defines inside the tubular chamber (41) a siphon for the accumulation of water and the formation of a liquid barrier that prevents the passage of wind from the outside towards the inside of the enclosure through the holes ( 43 and 42).

In the example shown, the upper hole (42) of the tubular chamber (41) additionally has a unidirectional valve (8) that allows the passage of fluid from the inner section (7b) of the longitudinal channel (7) into the interior of the tubular tube (41) and which prevents its passage in the opposite direction. In this exemplary embodiment, said unidirectional valve

(8) It is constituted by a tube that has a longitudinally movable shutter inside it between a lower opening position and an upper closing position.

Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration of the essential characteristics of the invention. which are claimed below.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The technical object of the invention is a "Framework for enclosures provided with sliding sheets". The longitudinal channel defined between guides, accumulates water in case of rain, being able to overflow the water towards the inner side of the enclosure in the case of heavy rains. The inventor proposes a system that allows to effectively evacuate the water that could access the inner section of the canal longitudinally, preventing the entry of air through the drain holes. For this, under the longitudinal channel a tubular chamber with an upper access hole for the water in the canal, and another outer drainage side. Using a siphon, for the purpose of water retention between both holes, this constitutes a barrier to the passage of air into the interior of the enclosure. The request consists of 3 claims. Being the 1st independent and the rest dependent. The first claim describes the essential technical characteristics of the invention. The 2nd claim defines the siphon configuration. The third claim refers to the use of a unidirectional valve in the hole located in the guide. Of the documents cited in the State of the Art Report, the document closest to the invention is considered US2003177699 (D01). D01 discloses a frame for enclosures provided with sliding leaves, comprising two vertical uprights and two horizontal, provided with parallel guides (50,60), which define a longitudinal channel between them (See Fig. 6). Presenting the lower horizontal upright below the longitudinal channel, a tubular chamber (V2), which has an access hole (A1) to the inner section of the channel (although not direct), and a side hole (A2) for access to the outer side of the enclosure, to effects of accumulated water evacuation in the inner section of the longitudinal channel (See Fig. 6). The differences between D01 and the 1st claim are: -D01 does not disclose the existence of lateral drainage holes in the guide. However, the use of these is General knowledge in the sector. See (D03 and D04) -D01 does not disclose the existence of a siphon in the tubular chamber (V2). Document JP2002309865 (D02) discloses a frame for enclosure provided with sliding sheets, comprising two vertical and two horizontal uprights, provided with parallel guides (51.61) that define a longitudinal channel (See Figs.), Presenting under the channel a chamber with upper holes (17a, 17b) for indirect access to the channel and side exit outdoor drainage (19). However, D02 does not disclose the existence of a siphon in the chamber. No document cited in the State of the Art Report, questions in an isolated or combined way the novelty and inventive activity of the 1st claim, nor therefore, of the dependents. Based on the above: - Claims 1-3 are new and have inventive activity. (Art. 6 and 8 of Patent Law 11/1986) State of the Art Report Page 4/4
