Definitions

  • the invention relates to a cramp with which modular form panels can be joined to each other simply, efficiently and rapidly, the cramp comprising a pair of jaws that clasp and clamp the frame sections of the boards to join, one of the jaws being displaceable and hence travelling to and from the other, clamping being effected by a simple wedge.
  • the document DE-A-3 545 273 discloses a cramp for joining modular form panels comprising a mounting section with a first pair of jaws integral with the sides of such section, a U-section clasping and travelling along the mounting section and a cross mounting pin or wedge.
  • One of the ends of the U-section extends into a second pair of jaws similar to said first pair of jaws.
  • the U-section has protrusions projecting from its inner faces constituting the guide means when the travelling jaws are displaced.
  • the sides of the U-section have been provided with windows.
  • the bottom edge of the mounting section has notches allowing insertion of the respective cross wedge which comprises skew longitudinal edge for the positioning thereof in the notches of the mounting section.
  • EP-A-0 311 876 discloses a similar cramp with has windows in both the sides of the mounting section and in the U-section. None of the windows have been provided with notches.
  • the cramp subject hereof is based upon the above-mentioned type of structure, i.e. it comprises three parts that will hereinafter be designated “male part”, “female part” and “wedge” or mounting pin, and is characteristic in that the male part, which comprises two mounting jaws that are defined by two wings integral with a mounting section, has a heel at its free end facing another heel with which the two jaws in the female part are provided, the female part comprising a U-section that clasps and travels along the above-mentioned mounting section, guiding itself on the same because the two jaws on this female or travelling part have two inwardly projecting bolts reaching into grooves provided to such end on the mounting section, thereby acting as guide means for the said female part and moreover a pivoting means therefor.
  • the two lateral faces upon which the jaws of both male and female parts and of the mounting section are moreover positioned, are provided with two longitudinal windows with notches towards either side, the aim being for the notches to be slanting and offset on one side with regard to the other in order to obtain a perfect fit for the relevant wedge or mounting pin, such comprising a lowered T-section with what could be designated the transverse branch having a skew longitudinal edge.
  • This wedge crosses not only the windows provided on the sides of the mounting section but naturally also the windows provided on the side wings of the female part, i.e. the windows backed to and clasping the sides of the mounting section, one of the windows being singularly rectangular and the one opposite being provided with a notch on one of the end sides to house the edge of the skew wedge wing.
  • the sections of the panels to join will be located between the facing jaws and clamping will be effected by merely inserting the wedge across the facing windows of the female part and the male part, i.e. in the latter case of the mounting section, so that as the wedge is pushed the travelling jaw or female part will move and clamping will take place, as appropriate.
  • the wedge or mounting pin has a tailpiece or transverse projection at its free end to prevent the said wedge from becoming detached once the aforesaid three-part assembly is mounted.
  • Figure 1.- Is a side elevation view of the cramp joining the two modular form panel sections to each other.
  • Figure 2. Is a plan view of the actual cramp, the dash line showing the slanting and offset notches that form part of the longitudinal window provided on either side of the mounting section, the said figure also showing the peculiar shape of the actual mounting pin or wedge.
  • Figure 3.- Is a profile view of the assembly shown in the above figure.
  • Figure 4.- Is finally a general perspective view of the cramp of the invention joining the sections of two adjacent panels to each other, as shown in figure 1.
  • the cramp of the invention has a male part comprising a peculiarly shaped tubular section (1) and a pair of jaws (2) integral with two of the sides of the mounting section (1), the latter also having on what could be considered the lower edge of such sides where the jaws (2) are fixed, two steps (1') the purpose of which will be described hereinafter.
  • the jaws (2) have heels (3) at their free end that shall reach into grooves or recesses (4') in the very sections (4) of the modular panels to join, as clearly shown in figures (1) and (4).
  • the sides of the mounting section (1) with which the two jaws (2) are integral are further provided with an elongate window (5) with notches on its longitudinal edges making up successive T shapes, thereby for these notches, with reference number (6), to be slanting and slightly offset, as shown in figure 2.
  • the cramp is additionally provided with a second travelling part having two further jaws (7) identical to jaws (2) and likewise provided with the relevant heels (3) at their ends, the jaws (7) projecting from the ends of a U-section (7') that clasps and travels along section (1).
  • the cramp is further provided with a third part that consists of a pin or wedge (8) shaped and working as described hereinafter.
  • the inner face of the jaws (7) is provided with two bolts (9) that reach into the steps (1') on the mounting section (1), such steps (1') constituting the guiding means for the part comprising the jaws (7) and the U-section (7') from which they project to travel as a whole, preventing run-off during travel from the mounting section (1) and allowing the female part to pivot about the said bolts (9).
  • the side wings of the U-section (7') are provided with a rectangular window (10) and one of these is recessed at one of its shorter sides, which recess naturally faces the window (5) provided on that side of the mounting section (1).
  • the wedge or cross pin (8) is T-shaped and one of its branches (11) has its slanting longitudinal edge precisely acting as a wedge while the other branch defines ribs on either side which adjust to and are positioned in the notches of the window (5) of the side wings of the mounting section (1), the said pin or wedge (8) also having a tailpiece (13) that prevents the same from becoming detached once the said three parts are mounted.
  • one of the windows (10) on the sides of the female or travelling part (7') is provided at one of its end sides, namely on the skew edge of the wing (11), with a central expansion-like notch, of considerably smaller width than the actual window (10), that is precisely positioned on the skew edge of the wedge (8) wing (11).
