  • connection of such channelled members may be made by sliding the connector into the chamber foimed by the opposed abutting channel formations with the edge channels of the connector receiving the abutting locking fingers.
  • the connector member is extruded of material having a measure of resiliency and having camming surfaces on opposite sides of the end grooves whereby the locking fingers at the entrance to the channel members to be connected, under a force directed to push the connector into the channel, acting on such camming surfaces effect a resilient flexing or bowing of the connector to reduce its effective width for passage beneath the fingers to a point where the camming surfaces clear the fingers and the edge grooves register therewith allowing the connector to snap to its full width with the locking fingers received and held in the edge grooves.
  • the connector member comprises a hollow extrusion of thermoplastic resilient material having an hour glass shaped cross section terminating in outwardly facing edge grooves and presenting sloping camming surfaces on opposite sides of the said grooves sloping inwardly up to the mouths of the grooves.
  • such connector members are provided on opposite sides thereof with integrally foimed arcuate cantilever resilient arms adapted to bear against the bottom walls of the channel of the members being connected to resist further inward movement of the connector once the camming shoulders on one side of the end grooves have cleared beneath the locking fingers and such fingers have entered the end grooves.
  • Figure 1 is a broken away perspective view illustrating a connector for connecting opposing box connectors, the connector being adapted for longitudinal sliding engagement with the inturned fingers of the box connector channels for effecting the box connector connection;
  • Figure 2 is a top plan view of an alternative connector adapted for lateral insertion into the channels of the box connectors to be joined and showing in dotted line its insertion into the channel of one of the box connectors;

  • Figure 4 is an enlarged end elevational view illustrating the connector of Figures 2 and 3 and illustrating how on bowing it can clear between the inturned locking fingers of the box connector under lateral pressure;
  • Figure 5 is a broken away perspective view illustrating an installation where end obstructions to the channelled member to be connected require the connector illustrated in Figures 2 to 4 to be inserted through the inturned channel fingers.
  • FIG. 1 With reference to Figure 1, there is shown a four- way box connector 1 interlocked with a hollow cellular panel 2 at one side and with a corresponding four-way box connector 3 by means of a connector generally designated at 4.
  • box connectors 1 and 3 and the panel 2 which are particularly adapted for use in erecting thermoplastic housing may be foimed as longitudinal extrusions having a reinforced core and a coextruded skin on exposed exterior surfaces as disclosed and claimed in my said copending application serial number 2,070,079.
  • the connector member 4 will comprise a longitudinal extrusion of thermoplastic material such as a vinyl chloride containing a reinforcing inorganic filler.
  • connector 4 can be extruded from other material such as aluminum and used to connect other than thermoplastic members which present opposed channels having inturned locking fingers.
  • Each of the box connectors 1 and 3 are of hollow rectilinear form presenting outwardly facing channels 5 having inturned fingers 6 at their entrance.
  • Panel 2 is formed with an end portion 7 of reduced width to fit within the adjoining channel 5 of the adjoining box connector and is further provided with grooves 8 to receive the inturned fingers 6 of the adjoining box connector.
  • the connection between the panel 3 and the adjoining box connector 1 is effected by sliding one longitudinally into the other with the fingers 7 sliding in the grooves 8.
  • the opposing abutting channels form a closed chamber into which the abutting fingers 7 project centrally of the width thereof.
  • Connector 4 comprises a longitudinal extrusion having a central web 9 terminating at opposite edges thereof with outwardly facing channels 10 which may taper slightly towards their open mouths 11.
  • the connector 4 is dimensioned to be received in the chamber formed by the opposing channels 5 of the box connectors 1 and 3 to span the interior thereof with the inturned fingers 6 received within the channels 10.
  • the width of the channels 10 is such as to hold the abutting fingers of the adjoining box connectors in snugly abutting relation while providing enough clearance so that the connector can be slid into interlocking relationship with the fingers over an extended length without binding.
  • the connector 4 provides a very simple means of connecting adjoining flange members and that it will be hidden internally within the closed chamber defined by the abutting channels 5.
  • the connector 4 of Figure 1 is intended to be slid longitudinally into interlocking position and it will be appreciated that there may be many instances where access to the box connector channels from the ends thereof may not be available in which case a connector must be provided which can be introduced laterally into the channels with the inturned locking fingers.
  • Figures 2 to 5 inclusive illustrate a preferred form of connector capable of effecting interconnection of opposing channels through the restricted entrance thereto defined between the opposed inturned locking fingers.
  • the connector 12 illustrated in Figures 2 to 5 comprises a hollow elongated extrusion formed of a thermoplastic material having a measure of resiliency.
