Description

Edge cover for a sliding leaf door

The present invention relates to a frame structure for a sliding leaf door intended to be integrated into masonry or plasterboard walls. The invention has been developed with particular, though not limiting, attention to an edge cover for a sliding leaf door.

Pre-existing technique

A sliding leaf door is usually mounted on a carrying frame, in the form of a box, inserted inside an opening delimited by a pair of masonry or plasterboard walls. The load-bearing frame comprises a stop post disposed vertically at the inner end of said opening and two side posts disposed vertically close to the outer end of said opening. The stop upright and the side ones are connected at the top by a horizontal crosspiece to which is associated a device for supporting and guiding the sliding leaf door.

The sash is framed by a jamb, or framing, structure coupled to a subframe of the load-bearing frame and provided with gaskets and dust brushes to protect the inside of the sash, and thus the sliding device, against external ambient agents, and to visually conceal the interior of the opening delimited by the pair of masonry or plasterboard walls.

On the frame structure are applied other covering and protection elements, called edge covers. The edge covers have an elongated shape in a vertical axial direction, and extend over the entire height of the subframe to which they are applied.

Various and different solutions of edge covers are known. A first solution comprises an edge cover composed of a single wall arranged juxtaposed and parallel to the lateral portion of the frame structure. This edge cover allows a quick application of the edge cover to the frame structure but leaves the front portion of the frame uncovered, thus sacrificing the aesthetic aspect in favor of the convenience of assembly.

Another solution of known type comprises a profiled edge cover so as to cover all the visible parts of the doorframe or frame structure. In particular, the ridge cover comprises a pair of walls adjacent to each other and forming a ridge, more preferably a right angle. The first wall is applied juxtaposed and parallel to the outer side portion of the frame and the second wall covers the front end portion of the frame.

In the two solutions of known type, the linings and the anti-dust brushes are engaged directly with the frame structure, or frame, and covered, or concealed, by the edge cover.

Numerous tests carried out by the contractor have shown to what extent, during the assembly phases of a load-bearing frame for sliding leaf doors and of the corresponding frame structure, the position of the edge cover in relation to the jamb or counterframe is not identical to that planned during the construction phase of the various elements. The reasons can be of a different nature, among other things, for example, the presence of dust or dirt inside the respective cavities or connection slots due to the assembly phases inside the masonry or slab walls. plaster.

This configuration affects the relative position of the trim or the brush in relation to the edge cover and/or the sliding leaf with the consequence of a reduction in their effectiveness and/or a deformation which can spoil the overall design of the sliding leaf door. .

An object of the present invention is to meet this requirement by providing an edge cover for a sliding leaf door which makes it possible to maintain the position and shape of the gaskets and/or dust brushes of a leaf door unchanged. sliding in relation to any frame structure and any type of counterframe.

Another object of the present invention is to provide an edge cover for a sliding leaf door which is able to be applied even to new typologies of frame structures without the need to modify any component thereof.

These objects have been achieved by the features of the invention.

For ease of understanding, like reference numerals have been used, where possible, to identify like common elements in the figures. It should be understood that elements and features of one embodiment may be conveniently incorporated into other embodiments without further explanation.

Reference will now be made in detail to the various embodiments of the invention, one or more examples of which are illustrated in the appended figures. Each example is provided purely as an illustration of the invention and is not intended as a limitation thereof. For example, technical features illustrated or described as part of one embodiment may be adopted over, or in combination with, other embodiments to produce another embodiment. It is intended that the present invention will include such modifications and variations.

It is also recalled that this description is not limited in its application to the details of construction and arrangement of the components as described below using the appended figures. This description may provide for other embodiments and be made or put into practice with other technically equivalent characteristics. The terms used below are purely descriptive and should not be considered limiting.

With particular reference to Figures 1 to 4, there is indicated generally at 130 an edge cover member for a sliding leaf door according to the present invention.

Edge cover 130 includes a pair of walls 131, 133 adjacent to each other and forming an edge, more preferably a right angle. The walls are elongated in a vertical axial direction and usually extend the full height of the doorframe structure to which they are applied.

A main wall 131 of the edge cover 130 is connected, without interruption, to a side wall 133. The visible parts, that is to say the external surfaces, of the walls 131 and 133 can be profiled in various ways to give the edge cover 130 any profile.

As will appear more clearly subsequently, the main wall 131 is applied juxtaposed and parallel to an outer side portion of a frame structure, and the side wall 133 is juxtaposed and parallel to a front end portion of the frame structure. jamb.

The main wall 131 comprises a plurality of cavities 132 made on the longitudinal extension of the non-visible part, that is to say on its internal surface, to allow the connection of the edge cover 130 to a frame structure.

According to a particularly advantageous characteristic of the present invention, an end portion 134 of the side wall 133 comprises a connection element particularly adapted to allow the selective connection of a joint to the edge cover 130.

According to the embodiment illustrated in the appended figures, the connection element comprises a cavity 138, or slot, formed along an axial direction transverse to the side wall 133, that is to say along an axial direction parallel to the plane defined by the surface of sidewall 133. Preferably, slot 138 extends substantially the full height of edge cover 130.

As illustrated in Figures 2 and 3, the slot 138 is particularly suitable for receiving a gasket 142 or a dust brush 140. In even more detail, the slot 138 accommodates an appendage or a tongue 143 of the gasket dust brush 140. The slot 138 is made with a height equal to or slightly less than the thickness of the tongue 143, so as to allow the embedding by friction of the latter inside the slot 138. The slot 138 is made with a depth equal to or slightly greater than the width of the tongue 143 so as to increase the opposition to the tangential stresses exerted on the trim 142 or on the dust brush 140 by a sliding leaf 102.

In Figure 4 are illustrated two edge covers 130 engaged with a doorframe structure and comprising a pair of gaskets 142 engaged with the end portion 134 of their respective side wall 133.

It appears obvious from the figure how, in the case where the position of the edge cover 130 is modified during the assembly phase compared to what is planned during the design phase, the lining 142 modifies its position without being deformed by interference with the jamb structure itself.

According to another particularly advantageous characteristic of the present invention, the slot 138 can be provided in an asymmetrical position in the thickness of the end portion 134 of the side wall 133. In particular, the slot 138 is delimited by an internal portion 135 and by an outer portion 137 of the end portion 134. According to one possible embodiment, the thickness of the inner portion 135 may have a value less than the value of the thickness of the outer portion 137 of the of end134.

Thanks to this solution, the inner portion 135 has a higher coefficient of elasticity than the outer portion 137, that is to say that the inner portion 135 has higher resilient properties than the outer portion 137.

Naturally, inside the opening of the end 134, it is possible to insert any other type of gasket.

Similarly, it is possible to provide various connection elements adapted to allow the selective connection of a joint to the edge cover 130, as long as these linings are connected to the end portion 134 of the side wall 133 of the edge cover. edge 130.

Referring to Figures 5 to 9, there is generally indicated by 1 a connecting element for a frame structure for a sliding leaf door.

The connecting element 1 comprises a profiled main body 5 with a profile section having four sides. A first side 10 comprises at least one coupling relief 12, for example but without limitation a pin or a journal or a lug. The mating relief 12 protrudes from the surface of the first side 10 by a predetermined height.

According to one of the possible embodiments, the relief 12 comprises a threaded or knurled outer surface or in any case profiled to promote the coupling of the relief 12 with a corresponding cavity.

The profile section includes a second side 20, adjacent to the first side 10 and forming an edge therewith. The second side 20 includes one or more elongated cavities 22, 24, 26 which extend orthogonal to the plane defined by the surface of the second side 20 and parallel to the plane defined by the surface of the first side 10. The cavities 22 have a depth and a predetermined quantity.

As illustrated on the , the connection element 1 comprises three cavities 22, 24, 26, at least one of the cavities 24 is open at both ends, so as to complete a through opening between the second side 20 and a third side 30 of the main profiled body 5 .

According to an advantageous characteristic, one of the open ends 25 of the cavity 24 comprises a funnel-shaped internal surface, for example frustoconical, which proves to be particularly suitable for accommodating in abutment a head of a fastening element, for example a screw.

On the illustrated is an end portion of a support frame 100 inside which is arranged a sliding leaf door 102. The support frame 100 is inserted inside an opening delimited by a pair of masonry walls or plasterboard 104, and comprises two side uprights 106 arranged vertically near the outer end of the opening. On each side upright 106 and on a corresponding abutment upright (not shown) arranged vertically at the inner end of the opening is fixed a counter-frame 120.

The side uprights 106 are connected at the top to a horizontal crosspiece 108 (illustrated in the ) to which is associated a device for supporting and guiding the sliding leaf door 102.

According to the embodiment illustrated in the , the counterframe 120 comprises on its own front end 121 a coupling relief 122, for example but without limitation a pin or a pin or a lug.

A connection element 1 for a frame structure for a sliding leaf door is fixed to the counterframe 120 by means of the coupling relief 122 inserted in one of the elongated cavities 26 of the second side 20 of the connection element 1.

On the the upper portion of the support frame 100 is illustrated, inside which the sliding leaf door 102 is exposed. sliding. The support and guide device 150 comprises a track 152 which extends longitudinally inside the opening delimited by the pair of masonry or plasterboard walls 104. Inside the track 152 are arranged slidably one or more carriages 154 to which the sliding leaf door 102 is fixed.

A connection element 1 for a frame structure for a sliding leaf door is fixed to the horizontal crosspiece 108 by means of a connection element, for example a screw inserted inside one of the cavities 24 open to both ends.

The edge cover 130 is fixed to the connection element 1 by means of the coupling relief 12 inserted inside the cavity 132 provided on the internal surface of the lateral portion 133 of the edge cover 130.

As clearly shown in Figures 8a and 8b, the connection element 1 for a frame structure for a sliding leaf door can be easily applied also to load-bearing frames with different conformations and technical characteristics.

For example, on the , the coupling relief 122 of the counterframe 120 is disposed in a more external position, that is to say closer to the edge cover 130, with respect to the coupling relief 122 of the counterframe 120 illustrated in there . In this embodiment, in fact, the coupling relief 122 is inserted in a different cavity 22 of the connection element 1, always with respect to what is illustrated in the .

Moreover, on the , the counterframe 120 does not include any coupling relief. In this case, the connection element 1 is fixed to the counterframe 120 by means of a connection element, for example a screw 127 inserted inside the through opening 24 of the connection element 1.

Thanks to this solution, the relative position of the connection device 1 with respect to the counter-frame 120 remains unchanged. Therefore, the edge cover 130 also remains in the same position with respect to the carrier frame 100, the respective masonry or plasterboard wall 104, and the sliding door 102.

In this way, disregarding the conformation and the technical characteristics of the support frame 100, the lateral portion 133 of the edge cover 130 will always remain in abutment on the external surface of the masonry or plasterboard wall 104, so as to perform its hedging function.

According to another particularly advantageous characteristic, the connection element 1 has a substantially box or cubic shape, or, in more general terms, a shape in which none of the dimensions, height, width and depth, of the connection element is very superior to the others, so as to be defined as connection block 1.

As illustrated on the , both the edge cover 130 and the counterframe 120 have a height substantially coinciding with the height of the carrying frame 100. Thanks to the solution proposed by the present invention, it is possible to arrange a plurality of connection blocks 1 along the counterframe 120 in predetermined number and positions. For example, for a carrier frame with a height of approximately 210 cm, only three connection blocks are sufficient to attach an edge cover 130 to the counter frame 120.

In this way, the assembly, disassembly and handling of the edge cover 130 are much easier and faster.

All details are replaceable by other technically equivalent elements. Similarly, the materials used, as well as the contingent shapes and dimensions, may be any according to the requirements without departing from the scope of the protection of the following claims.
