3 o As the buildings erected from some such components become more complex, there may be occasions where it is desirable to connect together a pair of members such as box connectors which present their locking channels with inturned locking fingers at the entrances thereto in face-to-face abutting relation with the opposed channels forming a closed chamber into which the abutting fingers project centrally thereof.
The connectors of the present invention solve the problem of interconnecting such channelled members.
According to the invention, the channel member connectors comprise elongated extruded members adapted to be received within the enclosed chamber formed by the abutting channels of the members to be 5 connected, said connector extrusion spanning the interior width of the channelchamber and presenting outwardly facing channels or grooves at the edges thereof for receiving the abutting inturned locking fingers and holding same in abutting relation.

~5 There are, however, many instances where it is not possible to effect such a sliding interlock because of obstructions at the ends of the abutting channels. To solve this problem according to one important embodiment of the invention the connector member is extruded of material having a measure of resiliency and having camming surfaces on opposite sides 2 0 of the end grooves whereby the locking fingers alt the entrance to the channel members to be connected, under a force directed to push the connector into the challnel, acting on such carnming 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 25 grooves register therewith allowing the connector to snap to its full width with the locking ~ingers received and held in the edge grooves. ~ ;

8~s~8 DETAILED DESCRIPTION ACCORDING TO THE PREFE~RRED
EMBOI)I~NTS
-With reference to Figure l, 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.
As discussed above, the box connectors 1 and 3 and the panel 2 which are particularly adapted for use in erecting the~moplastic housing may be formed 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.
Sirnilarly, for use in such building structures, the connector member 4 will comprise a longitudinal extrusion of thermoplastic material such as a vinyl chloride containing a reinforeing inorganic filler.
It will be appreciated, however, that 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 arç of hollow rectilinear form presenting outwardly facing channels 5 having inturned fingers 6 at their entrance.
3 o Panel 2 is formed with an end portion 7 of reduced width to fit within the adjoining channel S of the adjoining box connector and is further provided with grooves 8 to receive the inturned fingers 6 of thç 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.
~`` 2~3~
As illustrated in Figure l, when the two box connectors l and 3 are arranged contiguously with their channels 5 disposed in face-to-face relation, their inturned fingers 6 are in abutting relation.
In ef~ect, 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 l0 which may taper slightly towards their open mouths l l . The connector 4 is dimensioned to be received in the chamber formed by the opposing channels S of the box connectors l and 3 to span the interior thereof with the inturned fingers 6 received within the channels l0. The width of the channels l0 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.
It will be seen that 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 l is intended to be slid longitudinally into interlocking position and it will be appreciated that there may be many - ~ ;
2 5 instances where access to the box connector channels from the ends thereof may not be available in which case a connect~r 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 3 0 capable of effec~ing interconnection of opposing channels through the restricted entrance thereto defined between the opposed inturned locking fingers. According to the pre~erred form of this important aspect of the invention, the connector 12 illustrated in Figures 2 to 5 comprises a hollow elongated extrusion formed of a thermoplastic material having a measure of 3 5 resiliency. Such material may, for instance, comprise a polyvinyl chloridecontaining a sui~able inorganic filler in an amount to leave the polyvinyl chloride mixture with a measur~ of resiliency. Other suitable materials may ~ -be used as will be understood by those skilled in the art.
,~
-- 2~.3~8 As illustrated in Figules 2 to 4 the connector 12 is a hollow extrusion having an end profile or cross section of a generally hour glass configuration having a narrow waist portion 13 flaring out to a maximum thickness at points 14 and formed with edge grooves or channels 15. Between : ^s points 14 and the entrance to the grooves lS, the connector is provided with curved inwardly sloping camming shoulders 16 which extend up to the mouths of the channels lS. Projecting outwardly from the walls 17 of the hour glass configuration of connector 12 are arcuate resilient cantilever a~s 18 offset from each other on opposite sides of the connector and extending away from the closer of the grooves 15.
Figure 2 shows the connector 12 in a position ready for making the connection between a two-way box connector 19 connected to a panel 20 and three-way box connector 21 connected to pcmels 22 extending at right . .:
angles to panel 20.
The connector 12 is shown in dotted lines after having been inserted into the channel of the three-way connector 21 with its locking fingers 23 received in the edged channels lS and with one of the resilient cantilever arms 18 bearing against the bottom wall 24 of the three-way box ~ ;
connector channel.
Connector 12 also is shown as bearing against the bottom ~ :
channel wall 24 at its thickest point 14. ..
.~
Figure 4 illustrates the bowing or flexing capabilities of colmector 12 to permit it to be in~oduced into the bo~c connector channel 5 between the entrance restricting inturned fingers 23 ~mtil its reaches the 3 o position shown in Figure 2 spanning the width of the channel with the fingers 23 accommodated in the edge grooves lS.
In this connection, ag the connector 12 is forced laterally into the box connector channel, ~e channel ~ingers 23 are adapted to engage the camming shoulder 16 at either one or hoth edges of the connector causing the adjacent connector wall 17 to bow inwardly of the connector to reduce the effective width of the connector until the shoulder or shoulders 16 clear the inturned fingers 23 which allows the connector, as soon as these fingers . . .
~ 2~9~8 register with the edge groove or grooves 15, to recover to its full width and occupy the interlock position of Figure 2.
Figure 3 shows the connection made between box connectors 19 5 and 21 and this connection is made by pressing the box connector 19 with its associated panel 20 into abutment with box connector 21.
In such operation, the locking fingers 25 of box cormector 19 will act on the adjacent camming shoulders 16 to effect a bowing in of the 0 adjacent connector wall 17 to reduce the e~fective length of the adjacent sideof the connector until the camming shoulders clear beneath the locking fingers 25 which then can drop into the edge grooves 15 allowing the resilient connector to recover to its full width bridging the entire width of the box connector's channel.
During this operation, the resilient cantilever arm 18 bearing on -the bottom wall 24 of the three-way box connector channel will resist displacement of the connector wall to which it is connected further into the channel of the three-way box connector.
As seen in Figure 3, when connector 12 is in position the abutting fingers 25 and 23 of box connectors 19 and 21 are held in abutting position in the connector edge grooves lS and the connector 12 is totally contained within the chamber 26 formed by the channels of the abutting box connectors with the abutting locking fingers 23 and 25 projecting inwardly of the chamber midway of its width.
Just as the resilient cantilever arm 18 on the right hand side of the connector is illustrated in Figure 3 resiliently bears against the bottom wall 24 of the channel of the three-way connector, the corresponding -~
cantilever arm 18 on the opposite side of the connector resiliently bears against the bottom wall 27 of the two-way box connector 19 resiliently holding the connector in position in the chamber 26.
3 5 Figure 5 illustrates a situation where the connector must be forced into the channels of the members it is intended to connect through the restricted entrances thereto defined by the locking fingers. As shown, a wall 28 which may be made up of wall panels 29 connected by a three-way 3~f~ 9~8 box connector 30 extends between a floor 31 and a ceiling 32 with the box connector 30 presenting its channel 33 provided with its inturned locking fingers 34 facing into the area bounded by the wall and floor and ceiling. In this case, the box connector 12 is shown as extending the full length from 5 floor to ceiling ready to be forced into the box connector channel 33. The wall 35 to be joined to wall 29 is provided with a two-way box connector 36 corresponding to the box connector 19 ready to be assembled into abutting relation with box connector 30 with connector 12 assuming the position illustrated in Figure 3 when the walls are connected together. While it is lo usually preferable to have connector 12 extend the full length of the channelmembers it is to connect, it will be understood that its length may be selected - ^ ~
as desired and a plurality of spaced connectors may be employed rather than a ~ -single connector.
While specific and preferred embodiments of the invention have been clescribed therein, it will be understood that variations may be made without departing from the spirit of the invention or scope of the appended ;
claims. :

The connectors of the present invention solve the problem of interconnecting such channelled members.
According to the invention, the channel member connectors comprise elongated extruded members adapted to be received within the enclosed chamber formed by the abutting channels of the members to be 5 connected, said connector extrusion spanning the interior width of the channelchamber and presenting outwardly facing channels or grooves at the edges thereof for receiving the abutting inturned locking fingers and holding same in abutting relation.

To solve this problem according to one important embodiment of the invention the connector member is extruded of material having a measure of resiliency and having camming surfaces on opposite sides 2 0 of the end grooves whereby the locking fingers alt the entrance to the channel members to be connected, under a force directed to push the connector into the challnel, acting on such carnming 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 25 grooves register therewith allowing the connector to snap to its full width with the locking ~ingers received and held in the edge grooves. ~ ;

Connector 4 comprises a longitudinal extrusion having a central web 9 terminating at opposite edges thereof with outwardly facing channels l0 which may taper slightly towards their open mouths l l . The connector 4 is dimensioned to be received in the chamber formed by the opposing channels S of the box connectors l and 3 to span the interior thereof with the inturned fingers 6 received within the channels l0. The width of the channels l0 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.
It will be seen that 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 l is intended to be slid longitudinally into interlocking position and it will be appreciated that there may be many - ~ ;
2 5 instances where access to the box connector channels from the ends thereof may not be available in which case a connect~r 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 3 0 capable of effec~ing interconnection of opposing channels through the restricted entrance thereto defined between the opposed inturned locking fingers. According to the pre~erred form of this important aspect of the invention, the connector 12 illustrated in Figures 2 to 5 comprises a hollow elongated extrusion formed of a thermoplastic material having a measure of 3 5 resiliency. Such material may, for instance, comprise a polyvinyl chloridecontaining a sui~able inorganic filler in an amount to leave the polyvinyl chloride mixture with a measur~ of resiliency. Other suitable materials may ~ -be used as will be understood by those skilled in the art.
,~
-- 2~.3~8 As illustrated in Figules 2 to 4 the connector 12 is a hollow extrusion having an end profile or cross section of a generally hour glass configuration having a narrow waist portion 13 flaring out to a maximum thickness at points 14 and formed with edge grooves or channels 15. Between : ^s points 14 and the entrance to the grooves lS, the connector is provided with curved inwardly sloping camming shoulders 16 which extend up to the mouths of the channels lS. Projecting outwardly from the walls 17 of the hour glass configuration of connector 12 are arcuate resilient cantilever a~s 18 offset from each other on opposite sides of the connector and extending away from the closer of the grooves 15.
Figure 2 shows the connector 12 in a position ready for making the connection between a two-way box connector 19 connected to a panel 20 and three-way box connector 21 connected to pcmels 22 extending at right . .:
angles to panel 20.
The connector 12 is shown in dotted lines after having been inserted into the channel of the three-way connector 21 with its locking fingers 23 received in the edged channels lS and with one of the resilient cantilever arms 18 bearing against the bottom wall 24 of the three-way box ~ ;
connector channel.
Connector 12 also is shown as bearing against the bottom ~ :
channel wall 24 at its thickest point 14. ..
.~
Figure 4 illustrates the bowing or flexing capabilities of colmector 12 to permit it to be in~oduced into the bo~c connector channel 5 between the entrance restricting inturned fingers 23 ~mtil its reaches the 3 o position shown in Figure 2 spanning the width of the channel with the fingers 23 accommodated in the edge grooves lS.
In this connection, ag the connector 12 is forced laterally into the box connector channel, ~e channel ~ingers 23 are adapted to engage the camming shoulder 16 at either one or hoth edges of the connector causing the adjacent connector wall 17 to bow inwardly of the connector to reduce the effective width of the connector until the shoulder or shoulders 16 clear the inturned fingers 23 which allows the connector, as soon as these fingers . . .
~ 2~9~8 register with the edge groove or grooves 15, to recover to its full width and occupy the interlock position of Figure 2.
Figure 3 shows the connection made between box connectors 19 5 and 21 and this connection is made by pressing the box connector 19 with its associated panel 20 into abutment with box connector 21.
In such operation, the locking fingers 25 of box cormector 19 will act on the adjacent camming shoulders 16 to effect a bowing in of the 0 adjacent connector wall 17 to reduce the e~fective length of the adjacent sideof the connector until the camming shoulders clear beneath the locking fingers 25 which then can drop into the edge grooves 15 allowing the resilient connector to recover to its full width bridging the entire width of the box connector's channel.
During this operation, the resilient cantilever arm 18 bearing on -the bottom wall 24 of the three-way box connector channel will resist displacement of the connector wall to which it is connected further into the channel of the three-way box connector.
As seen in Figure 3, when connector 12 is in position the abutting fingers 25 and 23 of box connectors 19 and 21 are held in abutting position in the connector edge grooves lS and the connector 12 is totally contained within the chamber 26 formed by the channels of the abutting box connectors with the abutting locking fingers 23 and 25 projecting inwardly of the chamber midway of its width.
Just as the resilient cantilever arm 18 on the right hand side of the connector is illustrated in Figure 3 resiliently bears against the bottom wall 24 of the channel of the three-way connector, the corresponding -~
cantilever arm 18 on the opposite side of the connector resiliently bears against the bottom wall 27 of the two-way box connector 19 resiliently holding the connector in position in the chamber 26.
3 5 Figure 5 illustrates a situation where the connector must be forced into the channels of the members it is intended to connect through the restricted entrances thereto defined by the locking fingers. As shown, a wall 28 which may be made up of wall panels 29 connected by a three-way 3~f~ 9~8 box connector 30 extends between a floor 31 and a ceiling 32 with the box connector 30 presenting its channel 33 provided with its inturned locking fingers 34 facing into the area bounded by the wall and floor and ceiling. In this case, the box connector 12 is shown as extending the full length from 5 floor to ceiling ready to be forced into the box connector channel 33. The wall 35 to be joined to wall 29 is provided with a two-way box connector 36 corresponding to the box connector 19 ready to be assembled into abutting relation with box connector 30 with connector 12 assuming the position illustrated in Figure 3 when the walls are connected together. While it is lo usually preferable to have connector 12 extend the full length of the channelmembers it is to connect, it will be understood that its length may be selected - ^ ~
as desired and a plurality of spaced connectors may be employed rather than a ~ -single connector.
While specific and preferred embodiments of the invention have been clescribed therein, it will be understood that variations may be made without departing from the spirit of the invention or scope of the appended ;
