Definitions

  • the invention relates to a weaving frame with removable corner connections between upright lateral supports and upper and lower crossbeams formed by hollow profiles, connections which have at least one small fixing block which is integral with the directed face. towards the aforementioned crosspieces of the lateral supports and enters the free space in the end of the profiles, of which these crosspieces are formed, this small block being held in place in these profiles by means of at least one screw which is provided on the 'corresponding end of the crosspiece.
  • the main object of the invention is to offer a weaving frame with a new removable link which allows simple and practical mounting of the weaving frame and, moreover, ensures a solid and secure connection between the lateral supports and the crosspieces.
  • At least one spring is provided which makes it possible, in cooperation with the aforementioned screw, to block the small fixing block in the cross-member.
  • the spring is formed by a leaf of spring which extends approximately in the longitudinal direction of the cross-member.
  • the spring is fixed by at least one of its ends relative to the cross-member or the lateral support while the other end hooks elastically in a recess of an element which is fixed relative either to the lateral support or to the cross member, and it is held in this recess by means of the aforementioned screw, which blocks the small fixing block in the cross member.
  • the leaf spring is mounted on an insert which is fixed in the free space of the crosspiece.
  • the insert is formed by an L-shaped element, one of the branches of which forms the small fixing block and is practically parallel to the longitudinal direction of the cross-member, while the other branch extends approximately perpendicular to this direction, the spring being mounted on the free end of the other aforementioned branch and extending opposite the first aforementioned branch of the L-shaped element.
  • the weaving frame illustrated in the figures consists essentially of two parallel crosspieces situated one above the other, which are connected by means of removable corner links to removable upright lateral supports.
  • This cross member and also the lower cross member, not shown, is constituted by a hollow profile, while the lateral supports have, in this particular embodiment, an L-shaped profile, as is clear from FIG. 3.
  • the removable corner link comprises a small fixing block 3 which is integral with the face directed towards the cross member 1, the lateral support 2 and which penetrates into the free space 4, which extends over all the length of the profile. More particularly, the small fixing block is in one piece with the lateral support proper in this embodiment.
  • This small block 3 is held in place by means of a spring 6 and a screw 5, which is provided in the end adjacent to the lateral support 2, of the cross member 1, on the outside of the weaving frame.
  • This corner link is characterized by the fact that the spring 6 is mounted in this free space 4, with one of its ends, 7, fixed relative to the cross-member 1, while the other end 8 hooks elastically in a recess 9 made in the small fixing block 3.
  • This end 8 is held in the recess 9 and locked by means of this screw 5.
  • This screw is screwed into a nut 20 which is suitably slid into a groove 21 in the cross member 1, in the vicinity of the outer edge of the latter.
  • the spring 6 which is formed in this embodiment, by a leaf spring, extends approximately in the longitudinal direction of the cross member, the free end 8 of the spring being directed towards the adjacent end of the cross member.
  • the end 8 of the spring 6, which hooks into the recess 9 of the small fixing block 3, has an inclined contact surface 10 which cooperates with a corresponding inclined contact surface of the recess.
  • the angle alpha that these inclined surfaces 10 and 11 form with the longitudinal direction of the cross-member 1, is such that when the end 8 is pushed back into the recess 9, the small fixing block 3 is automatically pulled to its position in the free space 4 of the cross member and it simultaneously pulls the side support 2 upright, of which this small block is integral, against the cross member.
  • the angle alpha therefore forms a "sliding and pressure angle", the value of which can vary within relatively wide limits, thanks to the elasticity of the spring 6.
  • This sliding angle is for example between 20 and 40 °, and preferably is about 30 °.
  • this angle of sliding and pressure is obtained by bending the end 8 of the spring, which hooks into the small fixing block, in a loop around a pressure piece 12, which is tightened in the loop eyelet.
  • this screw which is only stressed axially, provides a solid connection both vertically and laterally.
  • the spring 6 still provides an additional advantage which is not without importance, in the sense that, by means of the exercise of axial pressure on the screw, it protects the latter against loosening.
  • the small fixing block 3 rests on a support block 13 which is locked in the free space 4 of the cross-member 1, against the lower wall 14 of the latter, for example by means of one or more rivets 15.
  • the spring leaf 6, which is therefore fixed relative to the cross-member 1, is mounted on an insert 16, which is fixed in the free space 4, for example by means of rivets 17.
  • the support block 13 is part of the insert, which is therefore constituted by an L-shaped element.
  • One of the branches forms the support block 13 and extends parallel to the longitudinal direction of the cross member 1, while the other branch 18 is perpendicular to this direction.
  • the end 7 of the spring 6 is curved around the free end of the branch 18 and it is fixed to the latter by means of a rivet 19.
  • FIG. 5 shows a second embodiment of a weaving frame according to the invention, which differs from the first embodiment essentially in that the spring 6 is mounted on the small fixing block 3.
  • the spring 6 has a U shape and it is stuck in a free space 22 formed in the small fixing block 3, which divides the latter into two parts 3a and 3b.
  • One of the branches, 6a, of the spring extends freely in this free space 22 and has an end 8 which is bent in a loop.
  • the other branch 6b exerts pressure on the underlying part 3b of the small fixing block.
  • the U-shaped spring 6 has, between the branches 6a and 6b and the base 6c, two arcs 6d projecting outwards, which are housed in two corresponding recesses 3c in the faces directed one towards the other part 3a and 3b of the small fixing block 3.
  • a cylindrical passage 23 is made, provided with an internal screw pitch, the axis of which extends parallel to that of the lateral support 2 and in which the screw 5 can be screwed to exert pressure on the loop end of the spring.
  • the screw 5 is free in an opening 24 made in the edge of the cross-member.
  • the recess 9 is provided in the L-shaped element or insert, in the angle between the two arms 13 and 18 of the latter. This insert is therefore blocked in the cross member 1 by means of rivets 15 and 17.
  • an important advantage of the removable corner link of the weaving frame according to the invention lies in that, thanks to the presence of the spring, the free end 8 of the latter hooks automatically in the recess 9 when the cross member 1 meets the lateral support 2 and automatically brings them to their position and keeps them there before the screw 5 is tightened.
  • the essential characteristic of the invention resides in the use of one or more springs which, together with one or more screws, make it possible to block the small fixing block in the cross-member.
  • the screw can cooperate directly or indirectly, for example by means of the fixing block, with the spring.
