A frame construction comprising a plurality of frame members secured together to form a geometric shape, preferably a rectangle. The frame is particularly adapted for framing art work, posters, diplomas, etc. Each frame member has a channel formed in the rear side thereof, and the corners of each member are angled. Two adjacent corners are held in an abutting relationship along the angled corners, to form a complementary angle, such as a 90 degree angle. The frame members are held together by connectors, with each connector having a pair of legs, with one of each legs being received in the channel of one of the frame members. The legs include pointed protuberances that are forced into the walls of the channels to securely hold the frame members together.
This disclosure relates to a framing assembly comprising a plurality of elongated members each of which is mitered on at least one end, the at least one mitered end of each elongated member being further provided with a tabular projection of substantially uniform crows section which projects essentially perpendicular to the longitudinal axis of the elongated member, a grooved portion extends substantially the entire length of each of the elongated members and has a cross sectional dimension conforming substantially to the cross sectional dimension of the tubular projection of the elongated member, the tabular projection of one such elongated member being inserted into the grooved portion of an adjacent elongated member to thereby define a rigid frame. A mitering guide is provided which is movably mounted within the grooved portion of the elongated member and which is readily positioned substantially anywhere along the elongated member to facilitate the cutting of the elongated member to any desired length.
A frame apparatus for mounting a display panel of the type having frame members and frame connectors, the latter with fasteners. Each frame member includes a plurality of outwardly-extending arm structures and a grooved fastener-bearing surface between each adjacent pair of arm structures. The connector bears against the underside of coplanar opposed strips extending at the ends of an adjacent pair of arm structures. The connector has wing-like compression members facilitating the connection of adjoining frame members. Such connectors are configured to allow multiple joint forms and butt joints at any angle.
A frame formed by frame sections joined end to end; each frame section having an elongated channel with a rear wall, spaced apart lips opposite the rear wall and defining a longitudinally directed slot and a side wall joining inner edges of each of the lips to a different edge of the rear wall. Securing adjacent pairs of the sections is a bracket having a pair of legs disposed at an angle substantially identical to the angle made by the frame sections, the legs fitting within the channels of said frame sections at their corner junction and having a width greater than the width of the slots so as to retain the bracket within the channels. A screw with an externally threaded shank is received by a threaded hole in each bracket leg. Each has an outer end adapted to accommodate a tool for producing axial rotation of the screw so as to force outer surface portions of the legs into engagement with inner surface portions of the lips and an inner end defining a contact surface engaging the rear wall of the channel and having an area substantially larger than the cross-sectional area of the shank.
A self-contained window unit that may be installed in a solid fuel burner or like device. The window unit comprises a safety shield which may consist of a glass pane and/or a safety screen, and a frame surrounding the safety shield. The frame is composed of frame elements fabricated in separate lengths with brackets at the corners of the frame to secure the frame elements together. Preferably there is a cushion element between the safety shield and the frame to minimize the risk of breakage. The unit may be mounted on the fuel burner by hanger brackets on the frame or by threaded studs carried by the brackets.
A deep groove or slot is provided at the joint between each stile and each rail to permit the accomodation, within the thickness of the element, of an appropriately shaped stiffener of suitable material such as stainless steel, aluminum alloy, galvanized sheet, brass, etc. In addition, both the stiles and the rails of each of the two elements of the window are provided on one of their surfaces with two deep grooves designed to accept suitable seals, while their outer surface is provided with steps, which match corresponding steps on the opposing element. The stiffener has an L-, C-, or Z-shaped cross section and forms essentially a right angle. After the stiffeners have been inserted in the stiles and the associated rails they thus disappear from view. The rails and the stiles can be of laminated construction, and after the individual layers have been bonded, they form either the grooves which house the stiffeners or the grooves which house the seals.
