Definitions

  • the present invention relates to furniture of the kind of tables, chairs, serving trolleis, writing desks, and other raised up furniture.
  • the supporting structure in such pieces of furniture is constructed of flat parts that allow new ways of manufacturing and assembly.
  • the invention includes the methods of design and manufacturing of the flat parts and the fixed or detachable unions for such parts.
  • the preferred material used in the development of this invention is the Medium Density Fiber ( MDF).
  • the supporters in this furniture are usually constructed of solid wooden laths which strong grain is oriented along the lath. From the laths some elongated parts are manufactured, some to be useful as supports in a vertical position and others for making the whole rigid in a horizontal position. The supporters thus constructed are rarely organized with its parts inclined or in open volumes, as it would be in the case of a wooden tripod, and are limited to parts having elongated proportions and slight curvature.
  • the laths can be artificially curved but it is expensive. A flat part of solid wood breaks easily if the stress applied to it does not follow the direction of its grain. For this reason this furniture is not manufactured with numeric control machines that would automatically cut out the parts from a wooden wide plank or board by following appreciately curved patterns. According to the present invention some different models have been successfully constructed from wooden medium density fiber useful to be manufacture with said machines.
  • Some supporters are constructed after open volumes and having their parts manufactured in injection forms, in which usually melting aluminium is injected. Forms compressing non-melting materials to shape the parts are not in use for the moment. In order to use them the parts should be substancially flat, even in their union portions, because the forms would work like a press that compresses the material between two surfaces being more or less flat.
  • the pieces of furniture which supporters are composed of vertical planes intersecting at a sole axis are unstable by definition under gravity loadings.
  • the object of the present invention is to provide raised up furniture which supporting structures consist of flat parts, and its methods of design and manufacture. More exactly, furniture in which its usable surfaces and volumes are raised up on flat parts having proportionate shapes that are put together in vertical or slightly inclined axes in a way that they define open volumes. It is the outline of said flat parts what imprints character to the piece of furniture, that is to say, it follows the shape of some legs, some arms, etc., in a certain style.
  • the present invention consists in a way of producing furniture of the kind of tables, chairs, writing desks, serving trollies, stools, etc., in which the supporting structure or frame is constructed of flat parts that are arranged after open volumes.
  • the present invention includes some improvements that offer numerous advantages in manufacturing, using and marketing of this kind of furniture, advantages that are compiled at the end of this chapter.
  • the supporting structure or frame is the part of the piece of furniture designed to support the usable surfaces or volumes in it. That is to say, to support the board of a table, the arm and back rests of a chair, or the drawers of a writing desk.
  • the invention therefore focusses on the design and manufacture of the vertical flat parts that altogether raise up the other portions of the piece of furniture from the floor. According to this, the supporter of the piece of furniture is considered to be formed by the flat parts and their union means.
  • the flat parts composing the structure are designed adjusting them to the stresses that could appear in each section of the part, giving to every section the minimum size that is possible for a normal use of the furniture.
  • the parts have proportionate shapes.
  • the parts Due to its flat shape, the parts can be fabricated by cutting them out from boards or planks, or as well be fabricated in forms.
  • the thickness of the parts can be:
  • the width in each section is the minimum needed to resist the stresses that can appear in it, that is why the resulting parts are proportionate-shaped.
  • the furniture can be made detachable by using some cylindric pieces (16) that are embedded in the flat parts that form the supporter. In said cylindric pieces are turned the screws that join the flat parts to the other structures of the furniture (see Figure 27).
  • the cylinders are placed with its main axis at a right angle to the plane of the part and has at least two threaded drills placed across the axis and near the heads of the cylinder. In them are turned the screws (17) that are then near both outfaces of the flat part and that assure transmitting the stresses that concentrate in them, specially in the case of the Medium Density Fiber (MDF) as seen before.
  • MDF Medium Density Fiber
  • the lengh of the cylinder is the same as, or approximately, the thickness of the part in which it is fitted and its diameter depends on the compressive strengh of the material in which it is fitted, being recommended in general the use of 15 mm. or bigger diameters with MDF.
  • the screws can fix the flat part to the horizontal structure (19) of the furniture directly (see Figure 27) or through an intermediate plate (21), that in the case shown in the figure is metallic (see Figure 28).
  • the horizontal structure (19) can also be subdivided as kind of intermediate plates that are screwed up to the top board (see Figure 40-b y 40-c).
  • Joining of the parts through cylinders is strong enough so that, in some models, there is no need of joining the flat parts to each other to form a nucleus.
  • another structure of the furniture generally the seat of a chair or the top of a table, is the one to act as a nucleus (see Figure 29).
  • a turning of the supporter round the central axis produces in this case stresses on the horizontal structure that are smaller than those produced while bending under furniture loading, so that this bending will determine its size.
  • the horizontal structure was a sole board of MDF, it is recommeded a minimum thickness of:
  • the cylindric pieces (16) to which the screws (17) are fixed can be placed on the edge of the part so that only half of the cylinder embedding is needed (see Figure 30).
  • Said pieces to which the screws are fixed also can have a shape adapted (30) to the flat part in the portion of the outline where it is embedded, and preferably are to be fabricated with forms (see Figure 31).
  • the cylindric pieces (16) can group together two or more flat parts at the same time it joins them to the horizontal structure (see Figure 32) in a way that the resultant section is the sum of the grouped sections.
  • the parts can have different outlines from each other elaborated in a way that when they are put together they compose a unitary design, in which the parts can be overlapped completely or just a portion of them.
  • the cylinder heads can be set in all cases out of sight if the drills do not get through the outface of the part, or if the cylinders are fitted and the holes are sealed up afterwards.
  • FIG. 33 Another embodiment of the union that follows the same working scheme the cylindric pieces do is the one illustrated in Figure 33.
  • Two pieces that can be equal to each other (31) have in one of their ends a cylindric portion (32) to be fitted into one of the sidefaces of the vertical structure flat part.
  • On the other end of each piece there is a drill, threaded rod, or the like, that allows fixing it to the horizontal structure of the piece of furniture. Both pieces are fitted one in front of the other and joined together through a threaded rod, a rivet, or the like, in a way that both pieces remain in sight.
  • Another way of joining the parts together that is very similar to that of cylindric pieces, consists in simultaneously using of glue and eccentric nut-fittings to allow assembly of the furniture with no need of using any tools or special installations.
  • Joining of the flat parts (18) together round the geometric central axis (1) can be made in a way that the edge of every part meets the face of another (see Figure 34). This enlarges the contact area of the union and avoids the need of preparing the edges to be joined with any special cut. This setting is either useful when a materialized central axis (1') is placed between the parts because it enlarges the contact area or because it allows the use of fittings like the one described next.
  • Joining of four parts together at right angles to form the supporter of a piece of furniture can also be made detachable by having cylindric pieces and screws that do not need adding glue between the parts to form a rigid union (see Figure 34 and 35).
  • the cylinders (22) are fitted in the parts having its main axis at a right angle to the plane of the part. They have a drill in the main axis that houses a screw (17) and another threaded drill across the axis in which another screw is turned. And so, four cylinders are joined by four screws forming a square that holds tight the parts together and round the materialized axis (1').
  • the recommended dimensions for the pieces of tables made of MDF board being 30 mm. thick are:
  • the screw heads can screen the sight of the cylinders or be housed inside them as seen in Figure 35, or as well be hidden, after the assembly, under a cap or finishing adhesive.
  • this characteristic can be used for making the padding detachable by using a board added as a padding support.
  • This piece of board or light panel can be joined to or get separated from the piece of furniture through some fittings (see Figures 36, 38 and 39).
  • fittings for attaching the padded board their can be used screws, suitcase fasteners, or wedges, being the most practical of all, the screws having wooden or non-slipping and soft touch rubber heads (26).
  • the heads can remain partially hiding behind the backrest support (27) (see Figure 36).
  • Furniture upholstery can be made removable if a good use of the detachable padding characteristics is made in the following manner (see Figure 36):
  • a cover (24) is held tight by having an elastic (25), zipper, or tape along its perimeter and therefore can be removed for washing it or substitute it for another one.
  • an elastic (25), zipper, or tape along its perimeter and therefore can be removed for washing it or substitute it for another one.
  • little hooks can be used to fix it to the board in the places of concavity.
  • the aesthetic result for the covers can be improved by sewing the elastic (25) directly to the cloth perimeter instead of housing it inside a fold of it.
  • the look is also improved by using elastic portions attached in both ends to opposite places of the perimeter in which this is straight (see Figure 39-f).
  • these can be fabricated in separate portions that will receive different finishing treatments and afterwards will be joined to form the whole part that is a portion of the supporter (see Figure 37). It is also useful for combining different materials or board thickness in the same part.
  • This method lies in using materials presented in flat shape, like board, plank, sheet, etc., to cut it out by following the patterns of the parts. We shall thus obtain the parts having the desired outline and the thickness of the board from which they are cut out.
  • This work of cutting out from the board can be done with an electric saw and some stencils, or preferably with automatic numeric control machines that cut the boards guided through electronic means. These machines allow to make use of informatic means for recording the shape of the different parts and for making necessary changes in them.
  • a single machine can mill, drill and sand the parts besides cutting them out.
  • the fiber can be compressed in forms having the shape of the different parts, thus avoiding the work of cutting the board and obtaining odds and ends left over.
