Sliding door for a sliding wall

Description

FIELD OF THE INVENTION

[0001] The present invention concerns a slider for a sliding wall which can be used advantageously but not exclusively in solar roofing structures, such as for example pergolas or other fixed structures for outdoors.

[0002] A pergola is a structure that has a covering and protection function, possibly also laterally, with a mainly integrating civil use in residential areas, but also in commercial, exhibition or public areas according to the regulations that govern the sector.

[0003] The pergola can also be provided with lateral covers, possibly sliding, such as blinds or glass panels, which allow to close and therefore insulate the space from the external environment.

[0004] The walls are equipped with respective sliding members, each comprising a slider disposed inside a special profile attached to the wall in correspondence with its lower edge.BACKGROUND OF THE INVENTION

[0005] In the field of solar roofing structures, it is known to dispose glass panels on one or more perimeter sides to laterally close the space defined below the roof, or inside the pergola. It is also known that at least some of these glass panels can be selectively opened and / or packed, by means of sliding glass panels known as slide glasses.

[0006] These systems provide two or more glass panels or walls, which can slide with respect to each other to selectively close or open a lateral access. As a rule, slide glasses have a sliding member with sliders or rollers, disposed in the lower part of each wall, and a series of parallel rails on which the sliders of each glass panel slide linearly. In the upper part, the glass panels slide freely inside corresponding profiles. There are also sliding members in which the slider runs along an upper guide and the glass is directly guided in the lower part.

[0007] Among known solutions, those which allow a parallel sliding of the glass panels are particularly appreciated, and in which the movement between the various glass panels is carried out by pulling one glass panel with respect to the adjacent one. The opening and closing mainly takes place manually, where the user pulls a first wall, located externally or internally to the pergola with respect to the others, and this wall takes the others with it. There are also solutions in which actuation takes place in an automated or semi-automatic manner. However, the costs of this type of technology are still too high for widespread diffusion.

[0008] Usually the slider is inserted in a dedicated compartment inside an aluminum profile that is attached to the lower edge of the wall. The walls are also provided with a seal between the lower portion of the profile and the ground, in order to block an unwanted inflow of water, for example due to rain, or to limit the entry of drafts, small insects, dirt or other. The seal is attached in a respective housing seating provided under the compartment of the slider.

[0009] Known sliding members provide that the slider is inserted from below, that is, from a longitudinal side, through an opening which then allows the wheels of the slider to pass, in order to allow the wall to slide.

[0010] Known sliders provide an internal sliding body, provided with swivel wheels, irremovably located inside a fixed external body made in a single piece. Known sliders are generally provided with end-of-travel and / or drawing elements or other accessory components, which protrude from the overall bulk of the slider to cooperate with corresponding adjacent profiles, in order to define a minimum distance between two glass panels, or to define the drawing of one glass panel with respect to the other.

[0011] One disadvantage of known sliders is that the end-of-travel and / or drawing elements must necessarily be attached from the outside, to the disadvantage of both the number of workings to be carried out on the profile, in particular holes for the screws, and also to the aesthetic component of the profile because, as described above, it leaves visible screws.

[0012] Document US 2005 / 011041 shows a slider comprising a containing body divided into two elements which can be coupled together. These elements are provided with through holes only for their reciprocal connection, and do not provide any connection element to attach an accessory to the outside of the slider.

[0013] Document EP 2476840 shows a slider of a known type, equipped with a lever to drive a locking mechanism. The lever is attached externally to the body of the slider by means of a screw, which is inserted from the outside with respect to the lever, and is therefore visible once the lever is mounted.

[0014] Documents US 4404771 and US 2018070779 both disclose sliders with external accessories.

[0015] There is therefore a need to perfect a slider which can overcome at least one of the disadvantages of the state of the art.

[0016] In particular, one purpose of the present invention is to provide a slider for a sliding wall that can be coupled with external accessories, for example an end-of-travel and / or a drawing element, without compromising the aesthetic component of the solar roof structure.

[0017] Another purpose of the present invention is to provide a slider that is faster and easier to assemble inside the corresponding profile.

[0018] Another purpose of the present invention is to provide a slider that allows to maintain and replace its component parts individually, without necessarily requiring the complete replacement of the part.

[0019] Another purpose is to perfect a method to assemble the slider.

[0020] The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.SUMMARY OF THE INVENTION

[0043] These and other aspects, characteristics and advantages of the present invention will become apparent from the following description of some embodiments, given as a non-restrictive example with reference to the attached drawings wherein: fig. 1 is a three-dimensional view of a profile and of a slider according to the invention; fig. 2 is a three-dimensional and partly exploded view of the slider of fig. 1; fig. 3 is a cross section of a portion of the slider of figs. 1 and 2; fig. 4 is a three-dimensional view of an accessory in a first operating configuration; and fig. 5 is a three-dimensional view of the accessory of fig. 4 in a second operating configuration.

[0044] To facilitate comprehension, the same reference numbers have been used, where possible, to identify identical common elements in the drawings. It is understood that elements and characteristics of one embodiment can conveniently be incorporated into other embodiments without further clarifications.DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0045] We will now refer in detail to the possible embodiments of the invention, of which one or more examples are shown in the attached drawings. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, one or more characteristics shown or described insomuch as they are part of one embodiment can be varied or adopted on, or in association with, other embodiments to produce further embodiments. It is understood that the present invention shall include all such modifications and variants, as long as they fall under the scope of the appended claims.

[0046] With reference to fig. 1, a profile 1 and a slider 2 are shown, which together form a sliding member for a wall made of glass or other material. As known, the slider 2 is able to be inserted inside the profile 1.

[0047] With reference to figs. 1, 2 and 3, the slider 2 is able to be housed inside the profile 1, more precisely in the third housing seating 15, so as to form with it a sliding member for a glass wall or suchlike.

[0048] The slider 2 comprises a sliding body 20, equipped with at least one wheel 3 mounted rotatable around an axis A substantially orthogonal to the wall during use, and a containing body 21 able to allow the fixed positioning of the slider 2 inside the profile 1. In a known manner, the sliding body 20 also comprises an adjustment member 20A for adjusting its height inside the containing body 21, for example a screw member that extends in a longitudinal direction from a front end of the sliding body 20 (fig. 2), and with respect to which it is at least partly screwed.

[0049] In order to allow the height of the sliding body 20 to be adjusted, through cam-type eyelets 21A are provided, made on the lateral surfaces of the containing body 21 and each having at least one portion inclined by an angle from 20° to 45° with respect to the lower edge of the containing body 21.

[0050] The wheel 3 comprises two pins 30 which extend laterally and are disposed coaxial to the axis of rotation A. The pins 30 have a length such as to also protrude from the sliding body 20, so that their end can cooperate with a respective inclined portion of the eyelets 21A, so as to slide inside the latter, following the defined inclination.

[0051] The screwing or unscrewing of the screw member 20A causes a displacement of the pins 30 of the wheel 3 in the cam-type eyelet 21A.

[0052] It should be noted that in the example shown, the eyelets 21A are closed, that is, they do not open in correspondence with a lower or upper longitudinal edge of the containing body 21.

[0053] The containing body 21 is equipped with a housing seating 21B inside which the sliding body 20 is inserted, during use. Conventionally for the person of skill in the art, both the sliding body 20 and also the containing body 21 have an elongated shape and are oriented in a same longitudinal direction when the sliding body 20 is inserted inside the containing body 21 (figs. 1 and 2).

[0054] According to one aspect of the invention, the containing body 21 comprises two containing elements 22 distinct from each other and reciprocally coupled with each other to define the housing seating 21B. Each element 22 is formed so as to have at least one external longitudinal side 22A and one internal longitudinal side 22B, both oriented longitudinally with respect to the longitudinal direction of the sliding body 20. When the containing body 21 is mounted, the external longitudinal side 22A faces toward the outside of the containing body 21, while the internal longitudinal side 22B is oriented toward the inside of the containing body 21.

[0055] The fact that the containing body 21 consists of two reciprocally couplable containing elements 22 allows to attach an external accessory, for example a clamping or a drawing member, attaching them from the inside of the containing body 21. In this way, the attachment members, in the form of screws, are not visible from the outside of the slider, to the advantage of the pleasant appearance of the sliding member.

[0056] For this purpose, at least one of the containing elements 22 is equipped with at least one attachment member 22C, which allows the attachment of an external accessory on the external longitudinal side 22A, accessible from the internal longitudinal side 22B of the element 22.

[0057] For example, the attachment member comprises a through hole 22C which extends between the internal longitudinal side 22B and the external longitudinal side 22A (fig. 2), able to accommodate, as an attachment counter-member 22D which can be inserted therein, a screw. In the example shown, each containing element 22 advantageously comprises a plurality of attachment members 22C.

[0058] Advantageously, the attachment member 22C is configured to allow the attachment counter-member 22D to be inserted from the internal longitudinal side 22B of the element 22. For example, the through holes 22C shown provide a truncated cone part configured to house a screw head with a corresponding shape. This truncated cone part is positioned in correspondence with the internal longitudinal side 22B.

[0059] Preferably, the containing elements 22 are inclined with respect to the axis of rotation A of the wheel 3, even more preferably they are perpendicular, as shown in the drawings. In this way, an external lateral accessory can be attached through the internal side 22B of the element 22.

[0060] In the example shown, the two containing elements 22 are advantageously two longitudinal half-shells, able to laterally surround the sliding body 20. However, it is possible to provide that one of the containing elements 22 corresponds to only a part of a first of these half-shells, for example a half, a third, a quarter or any fraction whatsoever thereof, and that the other of the containing elements 22 corresponds to the other part of the first half-shell in a single piece with the second half-shell.

[0061] Each half-shell 22 delimits, in its internal longitudinal side 22B, at least one seating zone 23 able to form, together with the other half-shell 22, the insertion seating 21A, and at least one contact zone 24 able to be put in contact with a corresponding contact zone 24 of the other half-shell 22 (fig. 2).

[0062] The half-shells 22 also have, on the internal longitudinal side 22B, a shaped hollow 25 made in a contact zone 24 and able to house the adjustment member 20A of the sliding body 20. Advantageously, the shaped hollow 25 is conformed to allow the screw member 20A to rise and fall together with the sliding body 20 with respect to the containing body 21, when it is screwed or unscrewed with respect to the sliding body 20.

[0063] Each containing element 22 provides a housing and axial contrast seating 22E for the head of the screw member 20A. This seating allows the screw member to rotate (screwing or unscrewing with respect to the sliding body 20), however it prevents it from moving axially with respect to the containing body 21, so as to make the pins 30 slide in the eyelets 4 and cause the selective lifting, lowering of the sliding body 20 with respect to the containing body 21. Advantageously, the housing seating 22E is disposed inside the containing elements 22, for example in an intermediate portion of the shaped hollow 25. The housing and axial contrast seating 22E is not provided in correspondence with a surface of the containing body 21.

[0064] In this way, the seating 22E contains two axial contrast elements, each one located on a respective side of the head of the screw member 20A, in the axial direction to the containing body 21. In addition to clamping the displacement of the screw member 20A in any direction whatsoever along the longitudinal axis of the containing body 21, this allows to make the head not visible from the outside of the slider.

[0065] In order to allow the screw member 20A to be driven, the containing body comprises a corresponding through aperture 25A, made for example by providing that the shaped hollow 25 is open in correspondence with an external surface of the containing body 21.

[0066] It should be noted that in the example shown in fig. 2 the attachment members 22C, that is, the through holes, are disposed in correspondence with the shaped hollow 25. However, they can also be disposed in correspondence with a contact zone 24.

[0067] It should also be noted that in the example shown, the inclined surface is also positioned in the shaped hollow 25, however, it can be disposed in any other part whatsoever of the internal longitudinal surface 22B of the containing element 22.

[0068] Advantageously, one of the containing elements 22 is equipped with a terminal closing member 26, able to close the end of the profile 1 when the slider 2 is inserted inside it.

[0069] According to another advantageous embodiment of the invention, the containing element 22 is provided, in the external longitudinal side 22A, with at least one stress relief member 27 (figs. 2 and 3), able to collaborate with a corresponding counter-member of an external accessory, for example a clamping accessory, in order to at least contribute to relieving the stress on the abutting glass panel. This prevents all the stress, in particular the shear stress, from being discharged on the screws that attach the clamping accessory to the slider.

[0070] In the example shown, the containing element 22 comprises a plurality of stress relief members 27, each comprising a hollow. The hollow can be linear or circular. If the hollow is circular it is advantageous to position it around a through hole, preferably coaxially to the through hole.

[0071] Fig. 2 also shows an external accessory 4 to be attached outside the slider 2, more precisely on the external longitudinal side 22B of a containing element 22 which forms the containing body 21. The accessory 4 shown is a clamping accessory, able to strike in abutment another glass wall so as to clamp its sliding relative to the wall on which it is attached. The external accessory 4 can be of a different type, such as a drawing accessory or other.

[0072] The external clamping accessory 4 advantageously comprises at least one attachment member 40, typically a hole, preferably blind, to allow it to be attached to the containing body 21 of the slider 2.

[0073] In the example shown, one of the two containing elements 22 comprises a drawing member 5 able to reciprocally interlock with a drawing member 5 of an adjacent wall, so as to determine the reciprocal movement by drawing between adjacent walls.

[0074] In the advantageous solution shown in the drawings, the drawing member 5 is made in a single piece on the external side 22B of each containing element 22. This solution, in the case of production by molding, allows to reduce the preparation costs of the molds. From an operational point of view, as a function of the disposition of the walls, one or the other drawing member 5 is removed from the respective containing element 22, in order to define the right and left sliders of the walls.

[0075] According to another advantageous aspect of the invention, the external accessory 4 also comprises at least one stress relief counter-member 41, able to cooperate with a respective stress relief member 27 of a containing element 22. In the example shown, the stress relief counter-member 41 provides teeth which protrude from the surface of the external accessory 4 and are shaped so as to be interlocked in the hollows 27. In particular, the teeth 41 can have a linear shape or a circular shape. In the event of a circular tooth, it is particularly advantageous to position it around a hole 40, even more advantageous coaxially thereto.

[0076] As can be seen from fig. 3, the external accessory 4, regardless of its function, is attached to the external longitudinal side 22A of a containing element 22 by means of screws 22D, inserted in the through holes 22C from the internal longitudinal side 22B toward the external longitudinal side 22A.

[0077] With reference to figs. 4 and 5, an alternative form of external accessory 6 is shown, able to be attached on an external longitudinal side of the slider 2. It should be noted that the slider 2 can be of the type described above or of a known type. The external accessory 6 is equipped with a position clamping device 60, able to clamp the corresponding wall in a pre-established position.

[0078] According to one embodiment not shown in the attached drawings, the external accessory 6 is associated with the slider 2 in an operating condition alternative to the accessory 4 previously described, that is, in cooperation with the latter and / or other accessories not described here, but commonly used in the sector of sliding glass walls.

[0079] According to a preferred embodiment, the position clamping device 60 comprises a clamping member 61 which can be displaced between an inactive position, in which it does not perform the clamping of the position of the wall, and a clamping position, in which the clamping of the position of the wall occurs.

[0080] With regard to the example shown, the clamping member 61 comprises a rod which can be displaced between a raised position, in which it does not prevent the free sliding of the wall (fig. 4), and a lowered position in which the pin protrudes from the position clamping device 60 and therefore prevents the free sliding of the wall (fig. 5). Obviously, the raised position of the rod 61 corresponds to the inactive position, while the lowered position of the rod 61 corresponds to the clamping position.

[0081] In order to displace the rod 61, the device 60 comprises an actuation member 62, typically a cam. In the example shown, the cam 62 is pivoted to the body of the external accessory 6 by means of a pin 63. The cam 62 can be displaced between a first position, corresponding to the inactive position of the rod 61 (fig. 4), and a second position, corresponding to the clamping position of the rod 61.

[0082] For example, in the first position the cam 62 does not act on the rod 61, which is maintained in the raised position by means of an elastic return member 64, typically a spring, suitably clamped between a seating 65 obtained in the body of the accessory 6 and an abutment member 66 of the rod 61, for example a circular edge of the head of the rod.

[0083] The position clamping device 60 can be manually driven or motorized. The example shown illustrates a manual drive, in which the device 60 is equipped with a gripping lever 67 that can be driven in order to displace the actuation member 62 between the first and the second position.

[0084] In practice, the gripping lever 66 is pivoted to the body of the external accessory 6 together with the cam 62, that is, by means of the same pin 63.

[0085] Advantageously, the cam 62 comprises a surface 62A for contact with the head of the rod 61 with a curved shape. Preferably, the curved shape has a development such that while the cam 62 is displaced from the first position (fig. 4) the contact surface 62A affects the head of the rod 61 and thrusts it progressively, until it reaches the second position (fig. 5).

[0086] It should be noted that figs. 4 and 5 show the external accessory 6 with the body in section. It should be made clear that the body preferably has a regular parallelepiped shape. The position clamping device 60 is preferably housed inside the body, and therefore not visible from the outside.

[0087] Obviously, the alternative external accessory 6 is equipped with attachment members in order to be attached to a longitudinal external surface of the previously described slider, or of a slider of the state of the art, and / or it can be equipped with at least one stress relief counter-member 41 described above.

[0088] A method for mounting the sliding member previously described is the following.

[0089] It is first provided to mount an external accessory 4 on one or both of the containing elements 22, providing to attach it from the internal longitudinal side 22B. Once the external accessory or the external accessories 4 has / have been attached, it is provided to reciprocally join the elements 22, disposing the sliding body 20 in correspondence with the seating zones 23, with the adjustment member 20A in correspondence with the shaped hollow 25. The two elements 22 are then reciprocally coupled by means of suitable attachment members provided in correspondence with the contact zones 24. If the terminal closing plate 26 is not already provided on one of the elements 22, it is provided to attach it to one end of the containing body 21, more precisely to the end that will face the open end of the profile 1.

[0090] Once the slider 2 has been assembled, it is inserted inside the profile 1. It should be made clear that the slider of the present invention can be used with profiles of a known type, but also with a profile as described in the Italian patent application 10201900020594, in the name of the same applicant.

[0091] It is clear that modifications and / or additions of parts or steps may be made to the slider and to the mounting method as described heretofore, without departing from the field and scope of the present invention as defined by the claims.

[0092] It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of slider, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.

[0093] In the following claims, the sole purpose of the references in brackets is to facilitate reading: they must not be considered as restrictive factors with regard to the field of protection claimed in the specific claims.
