The support members are displaceable between erect and collapsed positions whereby the transverse support member is prohibited from collapsing as long as at least one of the longitudinal support members is erect.

Abstract: A method, apparatus and system are provided for producing a molded part having a visually exposed surface comprising at least one side surface, the or each side surface being joined to a base surface at a corresponding substantially rectilinear edge. According to one aspect of the invention, the method includes the steps of: providing a mold comprising a mold surface complementary to said visually exposed surface; providing a film comprising a first face and a second face, and inserting said film into said mold such that said first face is facing said mold surface; closing the mold and injecting a molten material into the mold in a manner to urge said first face of said film into abutting contact with said mold surface and such that at least a layer of said molten material is formed in overlying relationship with said second face of said film; and allowing the molten material to solidify and possess said film.

Abstract: A method for making a part by injection molding and decorating a visually-exposed face surface and a visually-exposed side surface of the part in their entireties during the injection molding of the part.

Abstract: A collapsing table comprising a table top formed of a pair of pivotable table top half-sections hinged to one another at their at their adjacent edges along a center-line of the table and displaceable between an open position where the half-sections are coplanar, and a folded position where the half-sections overlap one another. Each half-section has at an undersurface thereof a transverse support member pivotally articulated thereto with a leg associated with each lateral edge of the transverse support member, and a pair of longitudinal support members pivotally articulated to the undersurface. The support members are displaceable between erect and collapsed positions whereby the transverse support member is prohibited from collapsing as long as at least one of the longitudinal support member is erect.

The recess comprises at least one projection protruding into the groove, and the groove is adapted to slidingly receive the edge of the sheet member with the projection snap-fitting into the opening, thereby providing a secure coupling between the sheet and receiving member.

Abstract: A hand truck comprising a platform fitted at opposed side walls thereof with a handle-engaging assembly, and a handle assembly comprising two parallel spaced arms, each fitted at its lower end with a platform engaging assembly. The handle is displaceable between three respective positions, namely a first position in which the handle is substantially up-right and which position is a pull/push position, a second position in which the handle is inclined and useful as a push position, and a third position in which the handle is and slidably received within the platform.

Abstract: A foldable support assembly, that may be for example, a folding chair, ladder or step-stool. The assembly comprises a first leg assembly and a second leg assembly that are hinged to each other near their tops so as to form a variable angle between them;. The second leg assembly comprises first and second legs, each leg being provided with a cam pin that projects from the leg. A support surface, upon which a load is to be placed, has a first edge, a second edge and two lateral sides. Each lateral side has an integral cam track configured to receive a cam pin projecting from one of the legs. The support surface is hinged at its first edge to the first leg assembly and supported at its second edge by the cam pins received in the cam tracks. Movement of the cam pins in the cam tracks during variation of the angle between the leg assemblies is coupled to rotation of the support surface.

Abstract: A system for injection molding a half-section of a collapsible table that includes a pair of interhinged half-sections. The system is provided with a mold whose dimensions are appropriate to the half-section to be molded therein, and a driven carrier adjacent one end of the mold having cautilevered therefrom parallel core rods that project into the mold. When the carrier is driven to cause the core rods to occupy an “in” position in which the rods are fully within the mold and extend the full length thereof, molten plastic is then injected into the mold to submerge the rods therein. When the plastic cures and rigidifies, parallel reinforcing beams are then created about the rods which are integrated with the resultant half-section. When the carder is driven to withdraw the rods from the mold which are now in an “out” position, the reinforcing beams are then hollow and the resistance of the half-section to bending forces is enhanced.

Abstract: A twin organizer pack adapted to carry a substantial load of fishing tackle or other pieces. Each pack in the twin is formed by a carrying case provided with a handle and a tray having a rectangular base supporting an array of cells to accommodate the pieces. Mounted on one end of the base adjacent each corner thereof is a pair of lugs having inwardly-projecting legs defining a T-shaped socket. Mounted on the opposite end of the base adjacent each corner thereof is a pair of lugs having outwardly projecting legs defining a T-shaped plug. To assemble the twin pack, two cases are stacked in back-to-back relation, with the plugs on each base then being next to the sockets on the other base and in line therewith. The cases are then interlocked by shifting one case toward the other to cause the plugs to enter the sockets, at which point the cases are in registration. Their handles are then brought into side-by-side relation to form a twin pack having a twin handle that can be grasped by one hand.

Abstract: An expandable shelf comprising a male member and a female member which are slidingly engaged, each of the members having longitudinal and transverse axes and each being divided into at least two corresponding sections along the transverse axis. Adjacent sections of the male member are separated by a groove parallel to the longitudinal axis, the male member comprising a row of spaced teeth extending from each section into the adjoining groove, the teeth of one section being aligned with the teeth of the adjacent section, each of two adjoining teeth defining a slot therebetween. The female member has an upper wall and has an aperture in the upper wall positioned above the groove when the male and female members are engaged. Also disclosed are a shelf assembly and a method for mounting a shelf onto a shelf assembly.
