Description

Device for guiding a sliding leaf relative to an opening

  The invention relates to the technical sector of doors and gates.

  To date there are many types of gates which can have different shapes and dimensions, being made of different materials, such as wood, iron, polyvinyl chloride (PVC). By way of an indicative example, in no way limiting, these gates can be executed from o solid or perforated panels, contiguous or spaced blades, in particular at the level of their upper part which can be straight or

  curved in one direction or in the other.

  Similarly, if we consider a cross section of these gates, they can have a rigorously constant thickness or likely to have dimensional differences resulting, for example, from the use of sleepers, assembly screws, .. Most often, these gates consist of at least one, but generally two leaves hinged on a fixed part of the opening to be fitted and generally delimited, for example, by pillars. Each leaf is therefore articulated with respect to one of its uprights to be opened in one direction or the other. The free articulation mounting of this type of gates, whatever their shapes, dimensions, design, material

  constituent, does not pose real technical problems.

  Gates have also been proposed, the actuation of which, relative to the opening to be fitted, is effected by sliding. This technique is used more and more, since it requires less space. In this case, it is no longer necessary to provide a large clearance space

2 2819845

  door leaves inside or outside. However, mounting, free

  sliding the gate poses certain problems.

  Generally, it is necessary to equip the upper part of the portal with a guide rail capable of cooperating with a roller mounted at the end of a bracket fixed to one of the pillars of the opening for example. The lower part of the gate is fitted with rollers cooperating with a rail fixed to the ground. As a result, this technical solution is limited to exclusively straight gates. In addition, the obligation to use a rail fixed at the upper part of the gate, greatly affects the aesthetics of the whole. Finally, the upper guide of the gate being carried out only by

  a roller, is not perfectly insured.

  It is understood that this technical solution considerably limits the choice of gates and does not allow the use, for example, of gates with

  non-contiguous planks with no upper crossmembers. Therefore, we-

  is forced to use a portal having, at its end

  upper, a straight crossmember for fixing the guide rail.

  The object of the invention is to remedy these drawbacks,

  simple, safe, efficient and rational way.

  The problem which the invention proposes to solve is to be able to ensure the guiding and the free sliding of any type of leaf whatever its forms, its dimensions, its design (spaced blades, contiguous blades, panels, straight shape, curved shape ), and whatever the nature

of the constituent material.

3 2819845

  To solve such a problem, it has been designed and developed a device for guiding a sliding leaf relative to an opening, comprising: - at least one bracket having fixing arrangements on a fixed part located near the 'opening; - The bracket has arrangements for mounting at least two assemblies arranged very substantially in a vertical plane; - the sets delimit, two by two, a guide and sliding space able to cooperate with the upper part of the leaf; - the assemblies consist of interchangeable elements selected according to the type of leaf; - the selected elements are able to adapt to the profile of the game

  upper leaf, as it slides.

  1 5 To solve the problem of ensuring the free sliding of the leaf, with guiding capacity, each assembly is constituted by at least one rotary member able to be driven freely in rotation, as and

leaf sliding measurement.

  To solve the problem posed of guiding the upper part of the portal, by creating a guiding space, the bracket is in the form of a stirrup of substantially U-shaped cross section delimiting two vertical wings joined, at their part upper, by a horizontal common branch, the lower part of each of said wings being arranged for mounting the guide assemblies in combination with the horizontal common branch, giving free access to the guide space. To solve the problem posed of guiding the leaf while allowing its free sliding and its withdrawal in the maximum position in order to completely release the opening, at least one of the vertical wings of the stirrup, has the fixing arrangements on the fixed part located near the opening, said arrangements being offset from the

mounting of rotary members.

  To solve the problem posed of guiding the upper part of the leaf with linear sliding capacity, each rotary member of each assembly is constituted by a vertical roller mounted freely in rotation between the upper horizontal common branch of the stirrup and

  the arrangements of the lower part of each of the wings.

  To solve the problem posed of being able to use the guide device for any type of leaf, including in cases where the leaf has - protruding parts at least one of the rotary members is constituted by a plurality of rings of different external diameters to take account of these possible excess thicknesses at the level of the upper part of the leaf, while allowing constant support and guidance as the leaf slides. Advantageously, the rings

  are mounted in combination with the vertical roller (s).

  Another problem which the invention proposes to solve is to be able to use the device including in the case where the upper part of the leaf has, for example, members for fixing a stiffness cross member. For this purpose, the rotary member or members have at least one

2819845

  circular groove for the free passage of raised asperities that may present

  at least one of the sides of the leaf.

  Another problem which the invention proposes to solve is to be able to also use the device in the case where the upper part of the leaf has a plurality of spaced blades with no continuous element

likely to constitute support.

  For this purpose, at least one of the rotary members is made up, for one of the sides at least of the leaf, by several aligned and spaced rollers mounted in a plate fixed to the base of the stem, one of the rollers at less being subject to the upper horizontal common branch of the gallows. -.- To solve the problem posed by stiffening the stem, in order to avoid any deformation when sliding the leaf, the rotary members are mounted in combination with a spacer tube centered on sockets enitre the upper horizontal branch and the arrangements of the lower part of the stem. The centering sleeves are carried by a concentric threaded rod mounted vertically between said branch and said arrangements, in relation to clamping members and with capacity for

transverse adjustment.

  The invention is set out below in more detail, using the figures of the appended drawings, in which: - Figure 1 is a perspective view, in schematic nature, showing the sliding of a portal by means of the device according to the invention;

  The figures of the accompanying drawings show the application of the guide device to a gate-type leaf. The portal, designated as a whole by (P), is illustrated voluntarily in a simplified manner, it being recalled that the guide device according to the invention has

7 2819845

  specific characteristics allowing the upper part of a portal to be guided with a view to sliding, whatever its type, the nature of the material of which it is made and its configuration. As of now, it should be considered that the few examples illustrated in certain figures of the drawings are given by way of non-limiting indication. The gate (P) is slidably mounted relative to an opening (O) delimited by two pillars (a) and (b). The base of the portal (P) has, in a known manner, rollers (R) intended to cooperate with a guide rail (C) fixed to the ground, at the level of the opening (O) projecting from the latter, on one side or the other, depending on the desired sliding direction of the gate. The guide device according to the invention is therefore located

  at the top of the gate (P).

  The device comprises a bracket (1) having fixing arrangements on a fixed part located near the opening. For example, the bracket (1) is fixed on the plain of the pillars (a) or (b) depending on the

  gate opening direction (P) (Figures 3 and 4).

  The bracket (1) is in the form of a stirrup, of cross section, substantially U-shaped, delimiting two vertical wings (la) and (lb)

  joined at their upper part by a common horizontal branch (lc).

  The lower part of each of the vertical wings (la) and (lb) is curved, substantially 90, to form two support legs (ld) and

  (1 e) arranged opposite, delimiting a free space (1 f).

  Between the upper horizontal branch (lc) and each of the support legs (ld) and (le) are mounted, two assemblies (E) delimiting, in pairs, a guide and sliding space (e) able to cooperate with the

8 2819845

  upper part of the leaf. The guide space (e) delimited by the two assemblies, is very slightly less than the space (1f) delimited by the two

opposite legs (ld) and (le).

  At least one of the wings (la) or (lb) of the stirrup (1) has arrangements for facial fixation, at the level of the upper part of the pillar (a) or (b). For example, the branch (la) has, at its upper part, oblong lights (lal) arranged vertically and, at its lower part, oblong lights (la2) arranged

horizontally.

  Advantageously, the branch (1a) has two vertical slots (lal) and two horizontal slots (la2) arranged one and the other in alignment.

  1 5 As will be indicated in the following description, the sets

  (E) consist of interchangeable elements selected according to the type of gate (P). These interchangeable elements are selected to adapt to the profile of the upper part of the gate as and when

  its sliding and this, whatever the type of gate.

  Each assembly (E) is constituted by a rotary member able to be driven linearly in rotation as the sliding of the

gate (P).

  In the embodiment illustrated in Figure 5, each of the rotary members is constituted by a vertical roller (2) mounted free in rotation between the upper common branch (lc) and each of the lower support legs (ld) and (le). The vertical rollers (2) have end caps (3) and (4) made integral with each of its ends, to ensure free coaxial mounting in rotation relative to a spacer tube (5) inserted between the upper branch (lc) and each of the lower support legs (ld) and (le). More particularly, the spacer tube (5) is centered on plastic sockets in particular (6) and (7), mounted concentrically at the ends of a threaded rod (8). The threaded rod is therefore mounted coaxially in the bore of the spacer tube (5) and protrudes, at each of its ends, from the bracket (1) to cooperate with clamping members in order to allow the spacer tube (5 ) between the upper and lower parts of said bracket (1) under a clamping effect,

while improving its rigidity.

  i5 The space (e) which appears between the two rollers (2) corresponds substantially to the thickness of the upper part of the portal in question. Note that the threaded rod (8) cooperates, at each of its ends, with any one of two holes (ldl - ld2) and (lel - le2) of oblong shape and formed in the thickness of each of the legs d 'lower support (1 d) and (1 e) and, correspondingly in the thickness of the upper branch (lc). If, for example, the holes (ldl) and (lel) are used, which are therefore located at one of the transverse ends of the legs (ld) and (le), use the oblong fixing lights (lal) and (la2 ) located at the opposite end to secure the whole bracket to the pillar. These provisions make it possible to completely retract the

  gate in maximum open position after sliding it.

2819845

  In order to take account of certain parts which one or each of the faces of the gate considered at its upper level may overflow, the or each roller (2) can receive, with free rotation, a plurality of rings (9) of different external diameters . Indeed, the rings (9a), of smaller external diameter, make it possible to escape any roughness or other raised parts, which one or each of the faces of the portal can have (FIG. 8). Obviously, the external diameters of the

  main rollers (2) are adapted to the thickness of the leaf in question.

  Likewise, in the case where the outer part of the gate is constituted by a plurality of blades which may or may not be contiguous, and joined together by an upper crosspiece (T) at one of their faces, the roller (2) considered on the side of this face, can be mounted in combination with a rotary member (10) having a central groove (10a). In particular, the groove (10a) makes it possible to escape any screws (V) ensuring the assembly of the crosspiece at the level of the blades constituting the upper part of the portal. For the other face of the portal, when the latter is constituted, at its upper part, by a plurality of blades mounted in a contiguous manner, the device can use a roller (2) as illustrated in FIG. 5. Obviously, the assembly of the rotary member (10) in combination with the roller (2) is carried out under the same conditions as

  those previously described for the mounting example in FIG. 5.

  By cons and as shown in Figure 11, in the case where the upper part of the gate is constituted by a plurality of spaced blades, the

1 1 2819845

  spacer tube (5) is integral with a plate (11) consisting of two spaced horizontal support plates (1 la) and (1 lb). Between the two plates (1 a) and (1 lb), is mounted a first rotary member (12) rotatably mounted relative to the spacer tube (5). In the same way as the rotary member (10), the rotary member (12) may or may not have a circular central groove (12a). On either side of the rotary member (12), two other members (13) and (14) are mounted rotatably mounted relative to spacer tubes (15) and (16) fixed by any known and appropriate means, between the two wings (1 la) and (1 lb} of the plate (11). The separation interval between the different rotary members (12), (13) and (14) is determined according to the interval which separates the gate blades, so that there is always at least one roller, resting on one of the blades, to ensure guidance

  constant linear when sliding the gate.

  The advantages are clear from the description in particular on

  underlines and recalls the application of the guidance device to any type of

door leaf in particular.
