Definitions

  • the present invention relates to an assembly apparatus for making frames or panels comprising a set of angles capable of each embracing an angle of the frame or panel and provided with guide means, a cable surrounding the angles passing in said guide means, and a tensioner to which two end segments of the cable are attached and which is capable of being maneuvered so as to tension a central segment of the cable around the angles the tensioner comprising a body with a longitudinal axis and means d 'attachment of said end segments of the cable.
  • the tensioner is integral with one of the angles and therefore, when the tension is applied, the distribution of the forces is not symmetrical.
  • the angle located on the same diagonal as that of which the tensioner is integral will undergo a different force from those which are transmitted to the angles located on the other diagonal.
  • US Pat. No. 4,047,710 also describes an assembly device and in this device, the tensioner is independent of the angles since all of these elements are mounted individually on the same base plate. However, the design of the tensioner is then such that the development of the forces is not symmetrical either.
  • the object of the present invention is to create an apparatus of the kind mentioned at the start which is capable of facilitating the making of frames of very variable dimensions and which can apply considerable tensile forces to the cable, without resulting in a torque of torsion or buckling stress on the frame elements.
  • the apparatus according to the invention is characterized in that the tensioner is a device separate from the angles which comprises maneuvering means capable of moving the hooking means relative to the body in the direction of said axis, by exerting thus a tensile force on said end segments of the cable, and curved entry means integral with the body, symmetrical with respect to said axis and intended to guide portions of the cable located between said end segments and the central segment so that these portions of the cable extend in a straight line parallel to one side of the frame, from two angles located at the ends of this side of the frame and up to said input means.
  • maneuvering means capable of moving the hooking means relative to the body in the direction of said axis, by exerting thus a tensile force on said end segments of the cable
  • curved entry means integral with the body, symmetrical with respect to said axis and intended to guide portions of the cable located between said end segments and the central segment so that these portions of the cable extend in a straight line parallel to one side of the frame, from two angles located at the ends of
  • the apparatus shown in the drawing can be used for making frames of very variable dimensions, the minimum dimension being of the order of 10 x 10 cm and the largest dimension being able to reach up to 1 x 2 m or even more. depending on the length of the cable used.
  • the device comprises, on the one hand, four angles designated by 1, on the other hand, a tensioner designated by 2, and finally a flexible metal cable 3.
  • the angles are preferably made of a light alloy and obtained by molding. They are formed of a rectilinear body with a length of about 15 cm consisting of two walls 1 a and 1 b oriented at right angles to each other. The angles also have an upper wall 1c and at mid-height, a middle wall 1d parallel to the upper wall 1c. As seen in fig.
  • each angle iron has a second opening 1g which is formed between the middle wall 1d d and the foot of the angle iron and which also extends in the angle of the angle iron, that is to say partly in the wall 1 a and partly in the wall 1b.
  • each angle iron further comprises a flat boss 1e extending outwards, the shape of which is that of a semicircle and the edge of which is provided with a groove 4.
  • a shell mold could be provided allowing these parts to be taken out without requiring any retouching, except for the tapping of two coaxial openings formed in the center of the wall 1c and in the center of the wall 1d. These threads are intended to each receive one of the two screws 5 and 6 which carry the plates 7 and 8 of the clamp associated with each angle.
  • Each plate 7 and 8 is connected to the end of the screw which carries it by a pin 6a or 5a which extends the screw and by a tightening washer fixed to the pin and engaged in a recess 7a or 8a of the plate.
  • the plates 7 and 8 are guided by the walls 1a and 1b, while, to ensure the stability of the screws 5 and 6, the walls 1c and 1d can be provided with bosses intended to increase the length of the threads which pass through them. In their apex at right angles, the plates are also cut at an angle to make the joints of the frames visible during assembly.
  • the four angles 1 can be provided with a base plate (not shown). They are intended to be mounted on any horizontal support, table or workbench, while the cable 3 is engaged in the grooves 4 and the rods A, B, C and D of a frame are placed between the plates 7 and 8 clamps. These make it possible to assemble frame elements of different thicknesses thanks to the fact that the two plates 7 and 8 are movable in the longitudinal direction of the angles. Whatever the thickness of the frame, it is thus possible to place the elements A, B, C, D so that their center of gravity is at the height of the flat boss 1e. Thus, during the tightening of the cable, no torsional moment is recorded. This arrangement is essential for ensuring the positioning of the frame elements so as to avoid any buckling.
  • the device described makes it possible to avoid the buckling. of the frame even if the internal surfaces of the bevels, intended to contain the film of adhesive between them, are not absolutely regular.
  • the tensioner 2 is used.
  • This will preferably be made of high-strength metal parts, iron, steel, or, if necessary, nickel silver or brass.
  • It consists of an elongated rectangular frame 10 provided at one of its ends with two slides in an arc 11 and 12 arranged symmetrically.
  • the two slides 11 and 12 and the crossbar of the frame 10 which is adjacent to these two slides will be made in one molded piece, while the rest of the U-shaped frame will constitute a second piece, the two pieces being fixed to each other, for example by screws.
  • the two longitudinal sides 10a and 10b of the frame 10 are of rectangular profile and serve as guide rails for a clamp 13 formed so as to slide along the frame.
  • This clamp 13 itself consists of three pieces: a clamp body 14, of approximately circular shape with a rectangular groove 14a around its periphery, a clamping piece 15, also in the form of a flat disc which is held on the body of clamp 14, and a fixing screw 16.
  • This screw passes through an eccentric hole 17 of the part 15 and engages in a thread 18 of the clamp body 14.
  • the clamp body 14 has two flanges 19 which center the part 15 relative to the clamp body 14.
  • the body 14 and the clamping piece 15 are each provided with two parallel grooves 20 oriented along the axis of the tensioner and in which the end segments cable 3 engage when tightening.
  • the clamping piece 15 also has two bevels 21 on its two sides facing the longitudinal elements 10a and 10b of the frame 10.
  • the clamp body 14 is fixed to the end of a threaded rod 22 which extends longitudinally between the elements 10a and 10b, which passes through a smooth hole made in the transverse part 10c of the frame 10 and on which a nut is engaged with fins 23.
  • a threaded rod 22 which extends longitudinally between the elements 10a and 10b, which passes through a smooth hole made in the transverse part 10c of the frame 10 and on which a nut is engaged with fins 23.
  • the two parts of the clamp 13 have in the axis of the screw flats which allow the establishment of this assembly between the two longitudinal sides 10a and 10b of the frame.
  • the arrangement described makes it possible to exert on the cable a considerable tensile force, which ensures the tightening of the frame elements A, B, C, D against each other.
  • the glue which covers the contact surfaces is subjected to a pressure such that it is pushed back inside the pores of the wood, which considerably improves the rigidity of the fixing.
  • the clamp may consist of a clamp body 34 in the form of a prism. More specifically, the part 34 has on each of its longitudinal sides a slightly inclined surface 35 a more strongly inclined surface 36.
  • the clamping part 37 which comes to fit on the clamp body 34 has for its part an internal groove limited by two oblique internal faces 38 which extend parallel to the surfaces 36, so that the two end segments of the cable 3 are pinched in the internal dihedral angles of the clamp body 34.
  • the threaded rod 39 and the wing nut 40 which screws on the threaded rod 39 make it possible to tighten the clamp and consequently to block the two ends of the cable.
  • provision may be made for the longitudinal screw 22 to be released from the clamp, which makes it possible to put it in place thanks to the flats (not shown) that the part 37 and the body 34 have in the longitudinal direction of the tensioner.
  • the implementation of the device is extremely easy since the tensioner can be grasped with one hand while operating, either the screw 16 in order to tighten the cable segments in the clamp 13, or the nut 23 so to tighten the cable. To perform these operations, the tensioner is largely free.
  • the four angles which rest on the flat support on which the operation is carried out are rigidly connected to each other via the cable.
  • the clamps 5, 6, 7, 8 are also capable of being easily maneuvered since the screws 6 are accessible from the upper end of the angles while the screws 5 are accessible through the openings 3 described above.
  • the heads of these screws 5 and 6 may be knurled heads or heads provided with hooking means such as external panels or internal panels (Imbus screws) capable of being actuated by means of a key or any other tool. .
  • the presence of the openings 2 and the corresponding cut-outs of the plate 6 makes it possible to monitor the state of the joints between the frame elements A, B, C, D, throughout the 'surgery.
  • the apparatus described makes it possible to carry out very delicate and very precise adjustment operations. It facilitates the assembly of frames made of profiled rods even in the case where, because of their profile, these rods are difficult to handle. In particular, thanks to the presence of movable clamps in the direction parallel to the angles, the positioning of the rods is possible with very high precision. This is what ensures the high reliability of the device described.
