Definitions

  • This invention relates to furniture and, more particularly, to the construction of tambours or rolling doors having natural wood surfaces and which are particularly suited for office f rniture.
  • a tambour is a rolling door or closure partic ⁇ ularly useful for furniture. While the word “tambour” is a noun, it is often used adjectively as, for example, "a tambour door” or "a tambour closure”.
  • the tambour comprises an assembly of parallel, narrow slats which are each hinged rela ⁇ tive to one another so that the tambour, as a whole, can be slid along a track to gain access to the interior of the piece of furniture of which it is a part.
  • Each tambour slat pivots relative to adjacent slats as the entire tambour moves on a track portion of which may be flat or curved or both. While most tambours roll upwardly, some roll laterally and some are even divided with part moving upwardly and part downwardly.
  • tambour slats were originally made completely of wood with their backs glued to a fabric to permit the slats to pivot relative to each other as their edges rode in tracks.
  • Probably the best known wooden tambour is that of a "roll-top" desk.
  • tambour slats, and hence the entire visible portion of the tambour door was made of plastic having integral pivot members or hidden hinges.
  • the slats were extruded from a single color plastic and, when cut off and assembled, produced a tambour door which was a single solid color.
  • Wood veneer on a plastic substrate slat is generally stronger than an all wood slat and provides greater security when assembled into a tambour than all wood slats.
  • the slats are normally cut lengthwise from plastic extrusions or rolled * metallic stock and randomly assembled side by side, it is difficult, if not impossible, to preprint a natural-looking pattern which is, for example, 4 feet in width and perhaps 6 feet in length when assembled. This would represent about 60 slats.
  • the tambour slat stock were pre ⁇ printed or veneered with a pattern approximating that of natural wood, any knot which was wider than the slat could not be accommodated in its entirety on a slat.
  • the same printed knot could show up, closely spaced, to an identical knot in an ad ⁇ jacent slat or as two half knots displaced lengthwise for each other on separate slats. This technique proved to be unacceptable because of a total lack of realism.
  • Each slat also known as a tambour slat, comprises a fabricated substrate which may be made of extruded plastic or rolled or extruded metal or the like.
  • the substrate has a front and back surface and first and second parallel edges. It is provided with interlocking pivot means which project from the back surface adjacent each parallel edges for pivotally connecting the slat in parallelism with adjacent similar slats.
  • a similar natural wood veneer layer is attached to the front surface of each slat.
  • the natural wood veneer layer comprises a series of joined natural wood strips extending lengthwise of the slat. The strips are secured to each other by an adhesive material which forms a visible joint between adja ⁇ cent strips with the grain of the individual strips extending lengthwise of the substrate.
  • the strips, and hence, the joints between them may be either parallel or wavy as desired.
  • Figure 1 is a schematic, perspective view of the front portion of a cabinet having a tambour embodying the invention in the closed position.
  • Figure 2 is a schematic, perspective view of the tambour of Figure 1 in the process of being rolled upwardly and around to the back of a cabinet which has been eliminated for clarity.
  • Figure 3 is a perspective end view of two adjacent tambour slats joined together.
  • Figure 4 is an enlarged perspective view of a tambour slat with a natural wood veneer layer attached to the front surface of each slat.
  • Figure 5 is a plan view on an enlarged scale of a portion of a tambour slat made in accordance with the invention, wherein the joints between adjacent wood strips are parallel.
  • Figure 6 is a plan view on an enlarged scale of a portion of a tambour slat made in accordance with this invention wherein the joints between adjacent wood strips are wavy.
  • FIG 1 shows, schematically, a tambour T in closed position on a cabinet C.
  • the tambour will also be referred to hereinafter as a tambour closure or tambour door. It comprises a plurality of identical tambour slats S which are hinged one to another. It may be equipped with a handle H, with or without a lock, to raise and lower the tambour and, when lowered, to lock it.
  • the tambour T in its entirety is pulled upwardly.
  • each tambour slat S reaches the top of the cabinet, it pivots relative to adjacent slats, each slat moving successively upwardly and rearwardly into a horizontal track ⁇ not shown) located at the top of the cabinet and down the back.
  • each slat After travelling across the top of the inside of the cabinet, each slat then pivots a second time and enters a vertical track located at the back of the cabinet.
  • the tambour assumes the position shown in Figure 2.
  • To close the tambour the process is reversed.
  • the tambour is closed, as in Figure 1, if the individual slats S differed substantially from one another in appearance, the general effect would not be pleasing. That is why prior art tambours often made of plastic are all the same color and identical with one another.
  • Each slat ( Figure 4) comprises a fabricated substrate 2 which may be, for example, extruded plastic or rolled or extruded metal.
  • the substrate has a front surface 4, a back surface 6, and first and second parallel edges 8 and 10.
  • the substrate may be from 1 to 2 inches wide between parallel edges.
  • Interlocking pivot means project from the back ⁇ surface 6 of the tambour substrate adjacent the edges 8 and 10 and include a female pivot member 12 and a male pivot member 14.
  • the male member 14 fits within the female member 12 to permit the tambour slats to pivot relative to each other.
  • a natural wood veneer layer V is attached to the front surface 4 of the slat S. Hot melt, thermoset, or thermoplastic adhesive has been found to be satisfactory for this process.
  • the natural wood veneer layer of each slat comprises a series of joined natural wood strips 20 extending lengthwise of the slat. There may be from about 10 to 35 strips on each substrate depending on the width of the substrate and the choice of the veneer.
  • the natural wood strips are joined to each other by adhesive material which forms visible joints 22 between adjacent strips 20. The selection of the color of the adhesive material adds to the grain appearance of the wood.
  • the thickness of the strips plus any backing and surface coating may be from about .01 to about .03 inches thick.
  • the natural wood veneer V is made by stacking many layers of wood veneer, which has been previous ⁇ ly stained to a desired, uniform color on a block - with a flat surface. Adhesive is placed between . each layer and is of a color selected to be har ⁇ monious with the natural grain of the wood. The assembled stack of veneer sheets is then sliced through from top to bottom by successive cuts which are parallel to the grain and not transversely of the grain.
  • a typical tambour slat substrate which may be approximately 1 1/4 inches in width, there may be as many as 10 to 35 individual strips, each coming from one of the layers of the stack from which it is cut.
  • each severed piece is virtually identical to every other severed piece and, consequently, when applied to the surface of the substrate, there are no unwanted half knots or partial cathedral arches.
  • the block upon which the sheets of adhered veneer were stacked would have a wavey upper surface.
  • the vertically cut veneer strips 20 would not have parallel edges and the joints would not be parallel and when assembled to a substrate, the edges would have to be trimmed to match up with the edges 8 and 10 of the sub- strate.

Abstract

Une fermeture à roulant (T) du type bureau à cylindre, comprenant une série de lattes similaires, parallèles et reliées entre elles (S) composant le roulant et pivotant les unes par rapport aux autres. Les lattes comprennent un substrat en tissu possédant des organes de pivotement s'emboîtant les uns dans les autres (12, 14) qui permettent à chaque latte d'être reliée à une latte adjacente et de pivoter par rapport à cette dernière. Une couche de placage (V) en bois naturel est fixée sur la surface avant de chaque latte et comprend une série de bandes reliées (20) en bois naturel s'étendant dans le sens de la longueur de la latte. Les bandes formant le placage peuvent être assemblées soit en parallèle soit de manière à former des ondulations.
