SWING GATE

  WITH HORIZONTALITY ADJUSTING DEVICE

  The invention relates to the technical sector of swing gates,

  said leaves being articulated with respect to a pillar.

  The installation of swing gates requires adjustments which are not always easy to execute in order to allow a horizontal leveling of the wings. This is due to the fact that the location of the grounds, and of the gate installation areas sometimes presents variations

awkward altitude.

  The leaves are not necessarily on the same level and this can create

  inconvenience during the operation of the portal.

  The adjustments are made empirically using, for example, thickness washers. This therefore requires each time a

disassembly of the assembly.

  The applicant was therefore interested in this problem, all the more so as the concept of a portal as a ready-to-assemble assembly is increasingly developed, including in a monobloc assembly ready for installation a bearing structure with two pillars, the gate leaves. being associated and articulated with

  pillars, themselves connected by a lower spacer bar resting on the ground.

  There is thus shown in Figure 1 such an assembly ready to mount gate. In this case there and to date, and to the knowledge of the applicant, there is no

  possibility of horizontal adjustment of the leaves in situ.

  The applicant's approach was therefore to take an interest in the problem posed and to seek a new and simple solution allowing adjustment

  quick of the horizontality of each leaf.

  From this problem posed, the solution found by the applicant requires a modification of the manufacture of the pillars receiving the gate leaves. According to a first characteristic, the casement gate, of the type comprising casements secured and articulated with respect to pillars, is remarkable in that each pillar comprises a tubular framework defined by two uprights disposed vertically in fixed support on a platform and receiving an upper protection plate, the two uprights being arranged at an angle and in that one of the uprights is arranged to allow the positioning and articulation of the vertical frame of the hinged leaf by means of connection means and rolling, and in that a tensioning device arranged inside the pillar in a diagonal plane is secured by a first end to the upper part of the upright allowing the positioning and articulation of the leaf and at its other end to a fixed point in the lower part of the pillar, said tensioner allowing the leaf to be adjusted in position by its action in elastic deformation of the mon so

  associated to allow the horizontality of said corresponding leaf.

  These and other features will become apparent from the

description which follows.

  To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings o:

  - Figure 1 is an overview of a swing gate according to the invention. - Figure 2 is a perspective view of a pillar according to the invention

  equipped with the device for adjusting the horizontality of the leaves.

  - Figure 3 is a top view of the pillar according to Figure 2. - Figures 4, 5 and 6 are front views illustrating the position of the

  beating in different situations after adjusting the horizontality.

  In order to make the object of the invention more concrete, it is now described in a non-limiting manner of embodiment illustrated in the figures

drawings.

  The swing gate is referenced as a whole by (1). It comprises two end pillars (2) identical to each other and receiving at 1 5 articulation in a known manner two leaves (3), the pillars being connected by

a spacer bar (4).

  According to the invention, the pillars are arranged in a new way to

  from a tubular frame (6). This includes two amounts (6a-

  6b) arranged vertically in fixed support on a lower platform (7) and able to receive in upper support a protective plate (8) or equivalent. These two uprights are arranged at an angle. One of the uprights (6a) is arranged to allow the positioning and articulation of the vertical frame (3a) of the leaf (3), being located in an angle of the volume of the pillar. Said upright (6a) has for this purpose in its upper part a tab (5) arranged horizontally and projecting, being arranged to receive rolling means (5a) of the vertical frame (3a) of the leaf (3), while that lower rolling means (5b) are arranged on the ground to allow the leaf to pivot for its

4 2811706

  open close. The vertical frame (3a) of the leaf is therefore parallel

and adjacent to the upright (6a).

  The spacing of the two uprights (6a-6b) and the upright (3a) constituting the vertical rising frame of the leaf (3) thus defines the body of each pillar and the internal volume for the reception of the driving elements (9) allowing relationship with appropriate mechanisms for opening / closing the leaves. A protective casing (10) in one or two parts (10Oa-lOb) in the form of profiled plates adjusts

  around the uprights and ensure the closure and tightness of the assembly.

  One of the parts (lOa) or (lOb) can constitute the access door inside the stack. The housing is fixed to the uprights by bolting

Or other.

  The vertical frame (3a) of the leaf (3), and therefore the leaf itself is capable of being adjusted in vertical inclination to allow a

  horizontal adjustment of the leaves depending on the terrain and place of installation.

  To do this, a tensioning device (Il 1) is arranged inside the pillar with a first end (1 la) fixed in the upper part of the upright (6a), and in the lower part of the pillar by its second end ( 1 lb) fixed position. Said tensioner is oriented in inclination as shown in the drawings inside the pillar, in a diagonal direction. This tensioner comprises in practice and in a nonlimiting implementation a lower or pulling bar (1 c) of great length whose lower end (1 lcl) is fixed to the base of the pillar and the upper threaded end (1 lc2 ) is coupled to a stirrup (1 ld) by means of a thread (1 ldl) by allowing the rotation of the stirrup on itself This stirrup forms a loop with another thread (1 Idl) at its other end allowing the positioning of a second bar (il e) or pulling of lesser length. The latter presents

2811706

  a threaded part (1 lel) with inverted pitch cooperating with the thread (1 ldl), while its end (11 e2) is fixedly secured to the upper part of the

amount (6a).

  Thus according to the invention, the adjustment of the stirrup will make it possible to increase or shorten the length of the tensioner taken as a whole while ensuring a slight effect of curvature by the elastic deformation of the upright (6a), resulting in its movement a slight movement of the leaf (3). This is sufficient to allow adjustments to the horizontality of the leaf depending on the ground conditions by raising or lowering the leaf as shown in Figures 4, 5 and 6. The tensioner is adjusted using a tool whatever is inserted like a key into the stirrup. This adjustment operation is carried out when the gate is installed. Any subsequent modification simply involves the removal of all or part of the housing. The advantages emerge clearly from the invention. We underline the

  simplicity of the concept, and ease of adjustment.
