Definitions

  • a corner joint more particularly a mitre joint between two frame members .
  • the invention relates to a corner joint, as defined in the first part of claim 1.
  • corner joint is disclosed in FR 2.322.572.
  • the corner connector is formed relatively rigid, in the sense that the first portion of each flange of the corner connector completely fills up the corresponding portion of the longitudinal hollow space of the respective frame member.
  • the first rigid flange portion narrows into the substantially thinner and therefore more flexible second flange portion which extends obliquely to the inner upstanding wall of the longitudinal hollow space.
  • the respective frame member would be subjected to a force that is directed towards the angular point of the corner connection, which would secure a completely closed mitre joint.
  • the contacting surface between these flange portions and the walls of the longitudinal hollow space of the frame members has been substantially reduced as compared with the well-known construction above referred to, so that even with a snugly fitting corner connector the insertion of the flanges of the latter into the respective longitudinal spaces will involve relatively little friction and the locking protuberance will "click" into the locking opening with certainty.
  • the latter will be accompanied by a force that urges the respective frame member towards the angular point of the connector, even in case of a non tapering form of the locking protuberance .
  • a further reduction of the friction between the first flange portion and the walls of the hollow space may be achieved by means of the feature that is mentioned in claim 2. Due to this feature only the part of the first flange portion that is located immediately adjacent the angular point of the connector needs to exactly fit in the respective longitudinal hollow space.
  • the central web extends beyond the bending point of the flange, as defined in claim 4. This increases the resiliency of the second flange portion.
  • a particularly effective corner joint is obtained with the features mentioned in claim 5 and 6.
  • the feature mentioned in claim 5 means that the second flange portion extends inwardly at a relatively large angle (of e.g. at least 15°) and comprises a relatively rigid part (that is strengthened by the extended central web) and a relatively flexible end part (which is not strengthened by the central web) .
  • Fig. 1 is a perspective view, on an enlarged scale, of a first embodiment of the corner connector according to the invention
  • fig. 2 shows a side elevation of the corner connector of fig. l
  • fig. 3 shows a simplified perspective view of a mitred frame member, adapted for use with the corner connector of fig. 1-2
  • fig. 4 is a side view of a second embodiment of the corner connector according to the invention
  • fig. 5 is an end view of one of the flanges of the corner connector of fig. 4, as seen from the right in fig. 4.
  • the corner connector shown therein is formed, e.g. from a suitable plastic material and consists of flanges A, which each comprise a first flange portion Aj and a second flange portion A 2 .
  • the first flange portions Ai when considered as extending upwardly from a longitudinal edge, are conencted at right angles, whereas the second flange portions A? extend from a bending location a at a certain angle (of e.g. 7,5°) inwardly.
  • the flange portions A 2 are slightly tapered as seen in their planes, and their ends are rounded off.
  • the flanges A are shaped as an inverted T, of which the flange 1 extends in an upright position along the outer side of the corner connector and the central web 2 is directed inwardly and parallel to the plane of the corner connector.
  • the flanges 1 of the first flange portions Ai have a height H, which corresponds with the internal height H 1 of the longitudinal hollow space 3 of the frame member X (fig. 3).
  • the flanges 1 have a thickness d, which is reduced as compared with the internal width B 1 of the longitudinal hollow space 3 of the frame member X.
  • a cross-shaped locking protuberance 5 is provided, which cooperates with a circular locking opening 5a in the inner upstanding wall 6 of the frame member X.
  • the central web 2 is strengthened on both sides by cross ribs 7, which guarantees a torsionfree fitting of the flange portions Ai, A 2 within the longitudinal hollow spaces 3 of the frame members to be connected.
  • the frame member X shown as an example in fig. 3 has been illustrated in a simplified form.
  • the longitudinal hollow space 3 is circumferentially closed, which contributes to a relatively large torsional and flexural strength.
  • the frame member X shown in the drawing is of the so called "backloader" type and it has to be provided with means for holding the photo or poster or similar image carrier to be framed within the rebate of the frame member.
  • a frame member provided with such holding means reference is made to NL 1011209.
  • the corner connector according to Fig. 4 and 5 distinguishes from that of Fig. 1 and 2 mainly in that the second flange portion A 2 in the example of fig.
  • a central web 2 of the second flange portion A 2 extends about halfway the flange 1 of the second flange portion, due to which the first part of the second flange portion has yet a relatively large flexural strength, whereas the end part - which is not strengthened by a central web - may flex easier.
  • the second flange portion A 2 When inserting a flange A of the corner connector of fig. 4-5 into the longitudinal hollow space 3 of the frame member X the second flange portion A 2 will elastically deform as indicated by dash lines in fig. 4.
  • the locking face 10 of the locking protuberance 5' that faces the angular point A 0 and encloses a sharp angle with the inwardly deviating flange 1, will become positioned substantially perpendicular in the dash line state of the second flange portion A 2 .
  • the relatively large pretension of the second flange portion A 2 will cause the protuberance 5' to enter into the opening 5a.
  • the locking face 10 will thereby tilt to the position it takes in the tensionfree state, which has the advantage that - entering of the locking protuberance into the opening 5a is accompanied by a still larger force that is applied to the frame member and directed to the angular point of the connector and the locking protuberance 5' is finally taking a "barb" position, which makes it impossible to pull the connector flange from the respective frame member and thus results in an optimally locked connection.

Abstract

L'invention concerne un joint d'angle entre deux éléments cadre à section généralement rectangulaire et pourvus d'un espace longitudinal creux traversant. Le raccord comprend une section d'angle de deux rebords à angle droit s'étendant à l'intérieur de l'espace creux longitudinal d'un élément cadre. Chacun desdits rebords comprend une première partie de rebord rigide, affleurante, reliée à une seconde partie de rebord plus souple. Cette seconde partie de rebord s'étend légèrement vers l'intérieur par rapport à la première et possède un élément saillant de blocage, à son extrémité libre, s'étendant transversalement vers l'intérieur. Cet élément saillant est destiné à coopérer avec une ouverture de blocage correspondante, située dans la paroi longitudinale verticale interne de l'élément cadre respectif. En coupe, les premières parties de rebord sont en forme de T, dont le rebord s'étend verticalement le long du côté extérieur de la section d'angle et l'âme centrale est dirigée vers l'intérieur parallèlement au plan de la section d'angle. Le rebord se prolonge, jusqu'à un point de flexion, par la seconde partie de rebord et comporte à son extrémité libre ledit élément saillant de blocage.
