Definitions

• Apparatus for linking . elements together and method of fitting the apparatus in an element Apparatus for linking . elements together and method of fitting the apparatus in an element.
• the present invention relates to an apparatus for linking elements together, said apparatus comprising a clamping box which is insertable into the edge of an element and provided with means for the engagement with a clamping box inserted in the edge of another element.
• the invention also relates to a method of fitting such apparatus in an element.
• the Applicant's Finnish patent 40488 discloses an apparatus of the above type for fastening two building elements by their edges to each other.
• This prior art apparatus likewise the other known element fasteners, is already moulded within the edge of an element as the element is manufactured. This requires extreme accuracy in the manufacturing step in order that the clamping boxes can be fitted properly and with required accuracy.
• One solution for fitting the clamping boxes in proper positions has been disclosed in US Patent publication 3 671 006.
• An object of the invention is to provide an element fastener of the above type and a method of fitting it in an element so as to eliminate the difficulties involved in the manufacture of. such element.
• an element fastener of the invention is characterized in thatthe trailing edgeof a clamping box is fitted with pivotable wings extending obliquely forward beyond the lateral surfaces of a clamping box in a manner that, when with ⁇ drawing said clamping box, the wings pivot away from the box and thereby build a barrier that ' after a certain distance prevents further withdrawal of the clamping box.
• Characteristic of the method is that the edge of an element is machined to form a recess for receiving the clamping box, that an adhesive is applied to the outer surface of said clamping box, that the clamping box is inserted into said recess a small distance inside the edge surface of the element, and that the clamping box is withdrawn a small distance out of the recess until it reaches a desired position relative to the edge of said element. This position is generally reached when the leading edge of said clamping box lies essentially in the same plane as the edge of .said element.
• the elements when using element fasteners of the invention, the elements can be manufactured and cast with ⁇ out clamping boxes and accurate fitting required thereby. This facilitates and accelerates considerably the actual manufacture of elements. As the clamping boxes are fitted afterwards by employing the method of the invention, the method can be carried out by means of an automatic machine for effecting the fitting quickly and accurately in desired positions.
• fig. 1 is a side view of the clamping box of an element fasten ⁇ er of the invention.
• fig. 2 is a plan view of the same.
• a clamping box 1 consists of two superimposed sheets provided with a box portion by means of punching.
• the superimposed trailing edge 1a of said box sheets is provided with pivot holes 3 which are engaged by loops 2a, 2b formed as hinges for wings 2, 2'.
• Wings 2 and 2' are positioned on either side of box 1 so as to extend obliquely forward beyond the lateral surfaces of said clamping box.
• the hinge loops 2a and 2b permit the pivoting thereof to the position illustrated by dash-dot lines in fig. 2.
• the clamping box is fitted in the element by first machining the element edge to form a recess for receiving the clamping box.
• a spring 4 which spring force is so small that it does not interfere with insertion of the clamping box into the edge recess of an element.
