Abstract:
A housing for apparatuses working in sound-absorbing, heat insulating or airtight conditions, e.g. air conditioning devices, the walls, the bottom and the ceiling of which are assembled of elementary, self-supporting insulation plates giving the whole housing a rigidity and good carrying capacity, each plate comprising two parallel metal sheets arranged at a distance from each other the rims of which are pressed together and bent as to form a shank and a channel, the metal sheets defining an interior space therebetween. According to the invention the shanks of two adjacent insulation plates serve on one hand for connecting the plates and on the other hand as a support of an insulating means, the interior space of each plate being completely filled with a hard porous material consistently connected with the inside surfaces of both the metal sheets.
Abstract:
A modular construction for rectangular doors, drawer fronts and like components of cabinets, closets, articles of furniture and the like is disclosed. Any such component includes a peripheral frame composed of four interlocked, preferably mitred, end butted side members, and a center panel or insert overlying the central opening of the frame and removably retained in place at the rear of the frame. The side members of the frame are injection molded of styrene or other suitable synthetic plastic material to basically identical constructions, each member being provided at one end thereof with an integral male connecting portion and at its other end with a matching recessed or female connecting portion to enable the four side members of the frame to be snapped together firmly at perfect right angles to each other. After assembly, the side members of the frame may be permanently cemented or bonded to one another at their junctures, and detachable back members may be screwed or otherwise secured to the back of the frame to assist in retaining the insert in place. All the structural units, i.e., the side and back members and the inserts, can be produced in a wide range of sizes. The invention thus makes it possible for a dealer to stock a relatively small selection of side members, inserts and back members of various sizes while yet being able to form therefrom a far larger number of combinations. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
Abstract:
A precast decorative panel is formed by filling a flexible mold to a selected level with an unset thermosetting resin and aggregates. After a nonrigid member, which is smaller than the receptacle, is placed on top of the mixture of resin and aggregates, a filler mold, which is smaller than the receptacle and substantially the same configuration so as to form a substantially uniform space therebetween, is disposed within the receptacle. This uniform space is filled with aggregates and an unset thermosetting resin. After the unset resin is partially cured to a soft gel, the filler mold is removed. Then, the partially cured resin is separated from the mold. This produces a panel having a textured top surface and a bottom surface with a drop edge extending therefrom along the entire periphery of the body of the panel.
Abstract:
A set of panels including a first panel and a second panel configured to assume a locked state. A separate tongue arranged in an insertion groove of a groove is configured to cooperate with a tongue groove provided in an edge section of the second panel for locking the first and second panels to each other in a first direction perpendicular to the first main plane, and the edge section is configured to cooperate with the groove for locking the first and second panels to each other in a second direction parallel to the first main plane. A bottom portion of the groove includes an elevated portion arranged at least in an outer section of the groove along the second direction, wherein an area of the elevated portion is at least 3% of an area of a rectangular bounded region extending along boundaries of the bottom portion.
Abstract:
Composed element, wherein this composed element comprises at least two panel-shaped elements, which substantially are formed from a board material; wherein said panel-shaped elements are interconnected at an angle by means of coupling devices including a tongue and a groove, which coupling devices substantially are made as profiled parts in the board material; and wherein said coupling devices also include locking elements, which, in coupled condition, prevent the moving apart of the tongue and groove. The panel-shaped elements are formed on the basis of board material in the form of particle board consisting of two or more layers, which in respect to the average fineness of the particles, show a different degree of fineness, namely a basic layer with coarser particles, more particularly chips, and at least one outer layer, or at least a more outward-situated layer, which is of a finer composition than the composition of the basic layer, in other words, with particles, chips, respectively, which on average are finer.
