BRIEF SUMMARY OF THE INVENTION
The present invention comprises a versatile, easy to assemble, readily customizable frame assembly to be utilized as a temporary or a permanent structure which may be covered by an external panel or fabric. Such a frame assembly, for example, may comprise a plurality of elongated horizontally disposed tubes connected in a rectilinear manner by, for example, a three way corner member, which each comer member mating with a vertical tube which is connected to a knuckle joint at its uppermost end. The knuckle joints are connected by horizontally disposed tubular members which may be bent in a curved fashion at the comers, and which tubular members are themselves abutively held connected together by a straight coupling member. The knuckle joints may be further connected to a corner brace, directed towards a central hub, connected thereto by a further set of knuckle joints. A bent or formed ring may be passed through each knuckle joint to form the hub, each of which knuckle joint is connected to a 5-way hub member. A center pole may be arranged to extend through the frame assembly from it's horizontal base, having a flange therearound and through a central bore within the 5-way hub for central support of the entire frame assembly, depending upon size and elevation.
The 5-way hub comprises a molded, central X-shaped housing, having a lower boss. The X-shaped housing has four connector housings equally spaced therearound at a 90 degree angle with respect to the longitudinal axis of the center bore. Each connector housing has a receiving bore formed therein. Each receiving bore has a closed innermost end and an open radially-outermost end. The central bore of the center cylinder has an open upper end which extends through the boss into an open lower end. Each connector housing of the 5-way hub is abutively attached to a knuckle joint by an internal tubular coupling sleeve in the respective receiving bores. The internal connector or coupling sleeve connects the receiving bore of each respective connector housing on the 5-way hub with a corresponding receiving bore on a connector housing of an adjacent knuckle joint. Each connector housing of the 5-way hub is connected to a respective knuckle joint by an internal sleeve matingly arranged therebetween, in their respective receiving bores.
A first knuckle joint and a second knuckle joint are articulably arranged adjacent one another to define a support for an internal tube arranged therebetween. The tube may be ribbed, and it may be formed in a curved manner as by heat from a heating lamp, a heating element, or a heated blanket or the like. A knuckle joint assembly is thus comprised of a first knuckle joint and a second knuckle joint. Each knuckle joint has a connector housing having a receiving bore extending therein. The receiving bore, as aforementioned has an inner closed end, and an open second or outer end. The receiving bore has a longitudinal axis which is coaxial with the longitudinal axis of the connector housing. The connector housing has an adaptor ring unitarily formed at the closed end of the connector housing. The adaptor ring has an annular surface which mates against a corresponding annular surface of a corresponding adaptor ring of a second knuckle joint of the joint assembly. The second knuckle joint is unitarily formed with a connector housing. The second knuckle joint connector housing has a receiving bore in a manner similar to that of the first knuckle joint. A cylindrically-shaped sleeve may be inserted through the respective bores of the respective first and second adaptor rings to connect the two knuckle joints together. The sleeve may be comprised of an elongated tube or the sleeve may be comprised of a shortened tube which is adapted to permit a smaller diameter tube to be inserted therewithin.
The elongated tube between adjacent knuckle joint assemblies on the frame assembly may have a supported tube carried thereon. The supported tube would be parallel to and adjacent the carrier tube which is arranged between adjacent knuckle joint assemblies. The carrier tube would have one or more “slip T” saddle connectors therewith.
The “slip T” saddle connector comprises an adaptor ring, unitarily formed with a connector housing saddle. The adaptor ring comprises a cylindrically shaped member connected to a generally cylindrically shaped saddle housing. The saddle housing comprises a saddle joint with a generally circumferentially shaped opening arranged transversely with respect to the longitudinal axis of the saddle housing. The longitudinal axis of the saddle is parallel to the longitudinal axis of the adaptor ring in a first embodiment thereof. The saddle comprises a formed opening of generally cylindrical configuration, which opening is an arcuate shape of between 180 degrees to about 240 degrees.
The slip T connector saddle joint in a further embodiment may have a connector housing arranged unitarily with the adaptor ring so that the saddle joint has a longitudinal axis which is transverse with respect to the longitudinal axis of the bore of the adaptor ring. In such a slip T saddle connector with a cross-aligned axis arrangement, a carrier tube may be arranged through the bore of the adaptor ring with the saddle connector housing biasedly engaging and 'slidably supporting a support tube, the axes of each tube being transverse with respect to one another. The saddle connector housing has its angularity of the opening such that the supported tube is snapped into the opening or maybe slid therethrough by virtue of the greater than 180 degree periphery of the saddle joint contact point arrangement.
The frame assembly as aforementioned, may include a straight T component, having an elongated adaptor ring with a bore extending therethrough, and a connector housing of generally cylindrically configuration, unitarily formed therewith, having a receiving bore therein. The receiving bore in this embodiment, has a closed innermost end.
A further component of the frame assembly described hereinabove, includes a unitary three way comer member having three connector housings, each of generally cylindrical shape, meeting at a common boundary, to define a connecting joint for the receipt of elongated tubes at the corner of a structure. Each three way comer member has its connector housings with their respective receiving bores having a closed inner end.
A further frame assembly utilizing some of the components in the aforementioned examples may comprise a rectilinear configuration of elongated tubular members defining a base. The rectilinear formation of the base comprises a pair of parallel side members and a pair of parallel end members. The parallel side members may each have a plurality of straight T components slidably disposed thereon. The connector housing of each straight T member may have an arcuately curved pole extending therefrom. Each opposed arcuately curved pole from the respective side portions of the rectilinear base may be connected by a curved tube, which curved tube is connected to its respective arcuate curved poles by an insert connector arranged therebetween. The frame assembly of this/these example/s thus may be covered by a flexible fabric, or frame panel arrangement so as to permit the safe enclosure of for example a bicycle, a motorcycle, a play house, or a tool arrangement therewithin.
The elongated tubing connecting the particular corners or knuckle joint assemblies of the present invention may be comprised of one and one quarter inch diameter PVC tubing or fluted tubing. Pins may be arranged between the respective connector housings and the elongated tubings received therein, to act as anchors for securement thereof. The heating of the elongated tubing may be accomplished by the aforementioned blanket or heated element so as to raise the temperature of the tubing to about 400 degrees Fahrenheit to permit that elongated tubing to be bent into a corner or into an arcuate shape as necessary. The tubular members may in one embodiment, be solid, they may have electrical conductors, lights or fluid ducting components connectively arranged therewithin.
Thus what has been shown is a unique framing assembly for the temporary or permanent construction of an enclosure which is readily customizable for a variety of connector components.
