Definitions

  • the present invention relates to a clip fixing for retaining plastics film material under tension.
  • This type of glazing has advantages over its more traditional counterpart in terms of, for example, weight and cost, and improved optical performance.
  • the film has to be stretched over a square or rectangular support frame, and held or secured in tension across the frame at each side member of the frame. This is accomplished by providing each side frame member with a special clip fixing in which the film can be retained under tension, and which is dynamic under load and has the capability of allowing the film to be released thereafter for replacement purposes.
  • a known clip fixing for this purpose is the subject of U.K. patent 1,586,247.
  • This fixing basically comprises a pair of channel members, one of which is integral with a res ⁇ pective side member of the support frame, and having internally profiled side flanks which are provided to coperate with corres- pondingly externally profiled, side flanks of the other freely mountable channel member, when positioned in inverted locked relationship therein.
  • a further area which requires to be improved in the prior clip fixing mentioned above, is in relation to its contribution to the reduction of the life span of the plastics film over and above that due to normal process of ageing.
  • This accelerated ageing of the plastics film has been found to occur in the region where the film exits the clip fixing, and in particular where the film passes over those surface portions of the clip fixing which are exposed to direct radiation and thus under the influence of high temperatures and ultra-violet radia ⁇ tion.
  • a clip fixing for retaining plastics film material under tension in a support frame comprising a first elongate channel member inte ⁇ gral with or attachable to the support frame or a respective support frame member, a second elongate channel member retain- able in assembly in the first channel member in inverted relationship to secure the film between opposing surface profiled side flanks of the channel members characterised in a pivot and socket joint formed between opposing flanks of the first and second channel members for retaining film, and permitting the second channel member to swivel from a disengaged position to an engaged position in said inverted relationship in the first channel member, a first lever on the second channel member extending from one side of said joint and arranged to set up tension in the film between the joint and a base member of said first channel member as the second channel member is moved to said engaged position, and a second lever on the second channel member extending from the other side of said joint to bear against the retained film entering the joint so that imposed tension in the film constrains the second channel member to maintain
  • the second channel member may be provided with • resilience, and the entrance to the socket made restrictive with respect to the pivot, so that in the disengaged position of the second channel member the film can be initially held between the cooperating surfaces of the joint, by force-fit engagement of the pivot in the socket.
  • the film thereafter passes around the free end of the first lever, " so that as the second channel ⁇ member is rotated into the engaged position, it is stretched and tensioned along the length of the first lever by the action of the free end of the lever physically yielding, due to its resilience, to pinch the film against the base member of the first channel.
  • the clip fixing for retaining and tensioning plastics film F shown in the drawing comprises a first channel member 1, usually part of a support frame across which the film is tensioned, and a second inverted channel member 2 which is able to engage the channel member 1 as shown to retain the film F under tension.
  • the channel member 2 is resiliently formed either by being constructed entirely of a plastics material for example, or having a metal core of aluminium ribbon for instance surrounded by a coating of plastics material, this latter con- struction being possible by known simultaneous extrusion tech ⁇ niques.
  • One flank 3 of the channel member 1 is provided with an elongate rib 4, which protrudes towards the interior of the channel member 1.
  • the rib 4 is part-circular in section, the circle being incomplete to the extent to form a connecting neck 5 to the wall portion 6 of the remainder of the flank 3.
  • the interior surface of the wall portion 6 has a straight section 7 between the base portion 8 of the channel 1 at right angles to it, and an inwardly curved return portion 9 running out into the circular surface of the rib 4.
  • the base portion 8 of the channel 1 is closer to the rib 4, than the remainder of the base 10, to form a radiused indent 11.
  • the flank 12 of the channel member 2 is provided with a socket 13 complementary to the rib 4, the socket 13 having an entrance E of lesser dimension than the diameter D of the rib 4, so that due to the resilience of the channel 2, the socket 13 can be inserted over the pivot by a snap-fit action, so forming a swivel joint J for the channel 1 on the channel 2, with the film F tightly held between their cooperating surfaces.
  • a lever arm 14 extends to one side of the socket 13, the lever arm 14 tapering to a resiliently deformable point 15, and having a straight inner surface portion 16 between the point 15, and a curved return elongate rib portion 17 to the interior surface of the socket 13.
  • the curved return 17 is complementary to the curved return 9 in flank 3.
  • a further arm 18 extends to the other side of the socket 13, the arm 18 being a continuation of the line of the base 19 of inverted channel member 2.
  • the other flank 20 of channel member 1 has a profiled recess 21 on its inner surface having a first surface constituting an insertion ramp 22 sloping inwardly with respect to the interior of channel member 1, and a second surface con ⁇ stituting a locking ramp 23 sloping outwardly with respect to that interior finally to terminate in a step portion 24 in the inner surface of the flank 20.
  • the flank 25 has its outer surface complementarily profiled to that of recess 21 constituted by a first surface 26 complementary to insertion ramp 22, and a second surface 27 complementary to locking ramp 23, and a bulbous tip 29 sub ⁇ stantially complementary to the step portion 24.
  • the film F is initially pinched between the cooperating surface of the swivel joint J by snap-fit insertion of the socket 13 on rib 4, with the flanks (20, 25) out of engagement, and stretched across the ends of the flanks 12, and 25, namely over point 15 and bulbous tip 29.
  • the channel member 2 is then rotated anti-clockwise on the swivel joint J, until the bulbous tip 29 contacts the insertion ramp 22, thereby holding the film F tightly between egress of the film F from the cooperating surfaces of the joint J and over the point 15 of lever arm 14, and the tip 29.
  • the tip 29 yields upon further anti-clockwise rotation to allow even- tual movement (corresponding to the engaged position of the fixing) into the cooperating step portion 24, and in this position, the film is then gripped between locking surfaces (23, 28), and ramp faces (22, 27).
  • the film F is pinched tight in this position between the point 15 and the base portion 8, and to this end, the point 15 resiliently yields as the lever moves into its final position, so setting up resilient stress at the end of the lever to "crush” or "pinch” the film into contact with the portion 8 so ensuring a water-tight seal.
  • the radiused indent assists in facilitating movement of the lever into its final position by reducing resistance to bending of the tip 15.
  • the lever arm 18 bears on the tensioned film F. 5
  • the tensional forces set up across the support frame are such as to cause deforma ⁇ tion of the frame support members and special compensatory features have to be introduced to avoid this. These involve incorporating special corner stiffeners, and leaving tolerance 0 gaps at the corner joints which close up after the tensioning process is complete.
  • the stress set up in the frame members is concentrated solely at the swivel joints of the clip fixing, and no stress is exerted in the engaged _ position of the fixing, along the other engaging flanks of the fixing, which are therefore simply necessary to position the film prior to tensioning by means of the other flanks incorpor ⁇ ating the swivel joint.
  • the arm 18 performs an Q additional service in the form of a radiation shield in that it protects the exposed surfaces of the joint J from harmful radiation which would otherwise cause excessive degradation of the plastics film.
  • the clip fixing of the invention moreover, in con- trast to the prior art, is capable of handling film material of varying thickness hardness and flexibility due to the leverage action attainable by menas of lever arm 14 in cooperation with the swivel joint J.

Abstract

Attache de fixation d'un film en plastique, comprenant une paire d'organes de canal (1, 2) dont l'un (2) est maintenu en relation inversée dans l'arbre (1). Un film de matériau plastique F est maintenu en tension par la fixation, grâce à l'interaction mutuelle entre les surfaces opposées profilées des flancs latéraux des organes de canal (3, 12) et (20, 25), au travers desquels passe le film F. Ces surfaces profilées opposées sont conçues spécialement pour fournir un nouveau moyen d'emboîtement par pivotement entre les deux organes de canal (1, 2) pour retenir le film F, tout en évitant l'effort résultant sur le cadre de support principal où l'organe de canal est fixé ou formé d'une seule pièce, ce qui permet également d'obtenir une liaison étanche à l'air et à l'eau entre les flancs latéraux (3, 12) et (20, 25) des deux organes de canal (1, 2).
