Description

DESCRIPTION

  The invention relates to a sliding gate not sus-

  hanged for vehicle or similar entrances, comprising a leaf which can slide in the longitudinal direction and a guide device which is fixedly mounted next to the passage served by the gate and which comprises two sets of rollers, these being at distance from each other in the sliding direction of the gate and cooperating with a

  lower guide rail thereof.

  A similar portal is known, for example by the

  German utility model no 89 06.344 U1. In such por-

  sliding rails, it is also necessary to have running rails or the like in the lower region of the gate. In the state of the art, a sliding gate is also known in which the lower profile of the

  leaf frame consists of a circular section tube

  laire which is maintained and guided on support and guide rollers. It is true that this conformation is relatively economical to achieve, since it is not necessary to install additional guide rails and the like. However, an embodiment of this kind requires the availability of rigid double posts provided with guide and support rollers in the region of the passage which

  is released by the gate when it is open,

  above the sets of rollers, because, because the lower profile of the frame is made in the form of a tube with circular section, the gate is not held

  by the only sets of lower rollers, and that it is

  milking mobile in rotation around the circular section tube

  inferior. We therefore need additional rigid posts.

  res to maintain such a sliding gate.

  Starting from this state of the art, the object of the invention is to create an unsprung sliding gate of the aforementioned kind which is extremely economical to manufacture.

  and which has high operational safety.

BAD ORIGINAL

  To achieve this goal, it is proposed that the lower guide rail be constituted by a lower profile of the leaf frame, that this frame profile is produced in the form of a polygon in cross section, and that it has an edge or a surface which rests on a roller arranged below the frame profile, as well as two oblique surfaces which are connected to this edge or

  to this surface and which are guided laterally by sur-

  guide faces of the roller, that the roller

  be made in the form of a biconic grooved roller

  that whose axis of rotation is horizontal, and that two support rollers are provided to bear on guide surfaces

  of the frame profile, on both sides of the long plane

median gitudinal of it.

  Thanks to this conformation, the construction of the

  sliding tail is considerably simplified, because only

  the two sets of track rollers which are arranged at

  each other in the sliding direction of the

  gate must be provided in the lower region of the gate

  sliding tail in which extends the frame profile which

  is made in the form of a polygon in cross-section

  dirty. Thanks to the fact that this profile is produced in this form, and that the rolling roller and the support rollers

  are adapted accordingly, we get that it is exclusive-

  Thanks to the running roller and the support rollers, the gate is held in a well-defined manner, so that it is possible to avoid having additional rigid double posts or the like, in spite of the thrust of the intervening wind. usually (transversely to the

sliding gate).

  A preferred development is that the pro-

  frame yarn is produced in the form of a profiled tube with a square or rectangular section which is laid on an edge and

  which extends symmetrically with respect to the median plane of the van

tail.

  Particularly preferred is the use of a profiled tube with a square section which is placed on an edge. The corresponding biconical grooved roller serves as a support for the edge of the profiled tube which somehow rests in the V formed by the groove of the roller, while the oblique surfaces which leave there rest on the surfaces of the cones of the roller & biconical throat. The support rollers serve as a stop, and they

  rest on the upper oblique surfaces of the sec-

  square transverse tion of the profiled tube on which they can roll. In this way, a very secure holding of the leaf is obtained by means of only two sets of rollers, these being arranged at a distance.

one of the other.

  A variant consists in that the frame profile is produced in the form of a hollow profile with a cross-section

  regular hexagon which is placed on an edge or on a surface

  face and which extends symmetrically with respect to the median plane

leaf.

  In the case where the frame profile is produced in the form of a hollow profile & section in regular hexagon, the arrangement can take place in such a way that

  hollow profile is placed on an edge, so that

  faces of the hexagon which are parallel to each other are oriented vertically. However, one can also realize the

  arrangement in such a way that surfaces of the hexago-

  which are parallel to each other are oriented horizontally-

  talement, the roller and biconical groove then having between the cones a large cylindrical area on which a surface of the hexagonal cross section can rest. With an arrangement of this kind, it is for example easier to weld end to end of the upright uprights of the frame or the like. In the case where the hexagonal section profile is placed on an edge, or in the case where a square or rectangular section profile is placed on an edge, it is true that the welding is a little more complicated to perform when the vertical uprights are welded, but these uprights can also have a notch at the location of the joint which is adapted to the shape of the profiled tube, so that a prior adjustment can take place before the

  welding, which can be useful for manufacturing.

  Another possible variant is that the frame profile is produced in the form of a hollow profile with a regular octagon section which is placed on an edge or on a surface and which extends symmetrically with respect to the

leaf mid-plane.

  To avoid seizing of the frame profile in the region of the biconical roller & groove, it is preferably provided

  that in the latter, which is arranged below the profi-

  the frame and oriented symmetrically with respect to the median longitudinal plane of the leaf, the cones form an angle which is slightly more open, and in particular more open by about 2 ', than the angle formed by the guided surfaces

adjacent to the frame profile.

  In addition, it is preferably provided that the axis of each of the support rollers is directed parallel to the plane

  which is defined by the corresponding bearing surface of the pro-

frame spun.

  To facilitate installation and handling, it is provided that the rolling roller and the support rollers are mounted on a common frame, roughly U-shaped,

  in which the frame profile can be installed.

  In order to be able to use a cost-effective material for the frame profile, provision is made to

  preferably that the surfaces of the frame profile on which

  the rollers the support rollers are provided with an anti-wear strip. The anti-wear strip can here be made of a wear-resistant material. It can be applied

  in a simple way on the corresponding surfaces of the pro-

  frame spun, for example by welding or riveting.

  In certain circumstances, it may also be

  ment provided that a support post of the height of the portal is disposed in the region where a set of rollers is disposed, this post enclosing by two guide rollers the upper edge of the gate leaf, which is constituted by a profile of frame, and the guide rollers can be supported by both

  sides along the frame profile.

  Although support posts of this kind are not necessary in themselves, it is nevertheless possible to provide such support posts, in particular from a single

  side. However, these support posts can be here constituted

  killed by a relatively light structure, because they have no loads to bear, or they don't have to bear

  that insignificant charges. In order to be able to operate

  operating such a sliding gate by means of an electric motor

  It is also planned that a drive chain engaged with a fixed chain wheel which can be driven by a motor is fixed to the lower profile of the frame, and that it is covered by a chain case fixed to this

frame profile.

  An exemplary embodiment of the invention is shown in the drawing, and is described in more detail in the following. The figures show: Figure 1 a sliding gate according to the invention in an elevation view; Figure 2 the same portal seen in the direction of arrow II of Figure 1; Figure 3 the portal seen from above; and: Figure 4 a sectional view of the portal taken along

line IV-IV of figure 1.

  In this exemplary embodiment, it is a non-suspended sliding gate which is intended for vehicle entrances or the like. This portal comprises a leaf 1 which can slide in the longitudinal direction and a guide device which is fixedly mounted next to the passage served by the portal and which comprises two sets of rollers 2, these being at a distance one on the other in the sliding direction of the sliding gate and cooperating with a lower guide rail of this portal. In the example of

  realization, leaf 1 proper of the portal is pro-

  skirted in the direction of the sets of rollers 2,

  this particularly concerns the lower beam of the door

  tail, however this extension is supported by the inter-

  median of an oblique beam 3. The sliding path of leaf 1 of the gate in the closing direction is

  limited by a stop post 4. The leaf 1 of the gate pre-

  feels on its front edge a bar 5 for protecting people which includes integrated switching elements

  intended to stop the gate when there is contact.

  The lower profile 6 of the frame of the leaf 1 is produced in cross section in the form of a polygon,

  and it has an edge 8 which rests on a roller of rou-

  Lement 7 disposed below the frame profile 6, as well as two oblique surfaces 9 which are connected to this edge and which are guided laterally by guide surfaces of the rolling roller 7. For this purpose, the latter is produced under the shape of a biconical grooved roller whose axis of rotation is horizontal. In addition, two support rollers 10 are provided which bear on upper guide surfaces 11 on both sides of the longitudinal median plane of the

  frame profile 6. This profile 6 is here produced under the form

  me of a profiled tube A square section which is placed on an edge and which extends symmetrically with respect to the plane

leaf median 1.

  The biconical grooved roller 7 is arranged below

  of the frame profile 6, it is oriented symmetrically with respect to

  port in the median longitudinal plane of the leaf 1, and its cones preferably form an angle which is slightly more open (of about 2 'for example) than that formed by the adjacent guided surfaces 9 of the frame profile 6, in order to avoid the seizure.

  The axes of the support rollers 10 are directed parallel-

  parallel to the plane which is defined by the supporting surface cor-

  corresponding 11 of the frame profile 6. As can be seen in particular in FIG. 4, the running roller 7 and the supporting rollers 10 are mounted on a common frame 12, roughly U-shaped, in which can first ask and

  place the frame profile 6 on the roller

  ment 7. The support rollers 10 are then mounted, then a suitable cover is installed and fixed, so that the elements of

  bearing are protected from manual contacts.

  The surfaces 11 of the frame profile 6 on which

  the rollers the support rollers 10 can be provided with an anti-wear strip 13. A support post 14 of the height of the gate can be provided in addition in the region where a set of rollers 2 is arranged, this post enclosing by two guide rollers 15 the upper edge of the leaf 1 which is constituted by a frame profile 16. The guide rollers are supported here along the frame profile 16 while rolling on the latter. The arrangement of the guide rollers 15 can be designed in such a way that they have a play with respect to the upper profile 16 of the frame, so that a support occurs only when extreme loads occur, while in the otherwise, the leaf 1 of the portal slides without support between the guide rollers 15. A drive chain engaged with a fixed chain wheel which can be driven by a motor (at 17) can be secured to the lower profile 6 of the frame, and it can be covered by a chain case 18 which is fixed

to this frame profile 6.
