Definitions

  • the present invention relates to a support comprising a seat element and feet each having an upper end fixed to the seat element and a lower end intended to be placed on a floor, the feet being inclined so as to cross in a middle zone where they are joined to each other by interlocking.
  • the "glued laminated wooden sled" type base presents few or no assembly problems, but it is relatively heavy and its price is much higher than a conventional base.
  • the reference US Pat. No. 3,396,933 describes a base of furniture, in particular a table, which is formed of generally rectilinear legs which all intersect in a median zone. Three forms of base are described comprising respectively four, six and eight feet. The type of assembly described results in a significant reduction in the section of each leg in the central criss-crossing zone, therefore a large reduction in the resistance of the base.
  • the object of the present invention is to avoid the drawbacks mentioned above, by providing a support provided with a base which is at the same time simple, rigid and durable, which can be manufactured in an inexpensive manner and which includes little or no part. metallic.
  • the invention relates to a support of the type indicated in the preamble, characterized in that the feet are three in number.
  • each leg is formed by a substantially straight piece of wood.
  • Said piece of wood can have a rectangular cross section outside said median zone.
  • At least one of the feet has an enlarged or bifurcated shape below said median zone, so as to present two support points distant from each other at its lower end.
  • the support comprises a central leg, arranged in an inclined position in a vertical median plane, and two lateral legs arranged in positions symmetrical to one another with respect to said median plane.
  • each lateral foot has, in its middle part, a notch for its nesting with the median foot, and in that at least one of the lateral feet has a notch for its nesting with the other side leg.
  • the median foot is arranged to fit onto the median parts of the two lateral feet joined to each other, so as to maintain said median parts assembled.
  • the central leg may include a central section with a reduced section defined on two sides opposite by two lateral notches having generatrix parallel to a direction of interlocking of the foot, the corresponding notches of the lateral legs being able to have a shape which corresponds to said reduced section.
  • All the surfaces of said notches can be flat.
  • each of the side legs is at the rear of the seat.
  • the support shown is a wooden chair comprising a seat element 1, a backrest 2 and a base 3 composed of three feet 4, 5 and 6.
  • the seat element 1 and the folder 2 can be of any construction, for example molded wood, glued laminated, and they can be made in one piece.
  • the feet 4, 5 and 6 have upper ends 4 ′, 5 ′, 6 ′ which are cut obliquely and slightly hollow to press against the underside of the seat element 1, against which they can be held for example by means of screws, glued pins or other usual joining members.
  • the three legs intersect and are fixed to each other in their middle zone, approximately halfway between the ground and the seat element 1 and they have lower ends 4 ⁇ , 5 ⁇ and 6 ⁇ which are also cut obliquely to rest on the ground.
  • the leg 4 is arranged in a vertical median plane 8 forming a plane of symmetry of the chair; it is inclined so that its upper end 4 ′ is at the rear of the seat element 1, while its lower end 4 "is in front.
  • the feet 5 and 6 are arranged symmetrically with respect to the median plane 8 and they are called "side feet". Their upper ends 5′and 6 ′ are located near the front of the seat element 1, while their lower ends 5 ⁇ and 6 ⁇ are located at the rear and ensure good lateral stability of the chair when the user is supported on the backrest.
  • FIGS 3 to 5 show in more detail the legs 4, 5 and 6, which can all be made from simple straight pieces of wood with rectangular cross sections. To make these feet, apart from the way of their upper and lower ends, lateral cuts are made in their middle part allowing their assembly by interlocking.
  • the central leg 4 has a front face 10 which is planar. It comprises two lateral notches 11 and a rear notch 12 which delimit a middle part 13 of reduced cross section of rectangular shape.
  • each lateral foot 5, 6 has in its median part, a lateral notch 14, 15 in the form of a groove with rectangular section extending over half the thickness of the foot and having the same width. than the other foot, which makes it possible to assemble the two feet 5 and 6 in the shape of an X, by lateral interlocking on their notches 14 and 15.
  • the feet 5 and 6 also have in their median part, respective notches 16, 17 which have faces inclined relative to the notches 14, 15 and which define, when the two feet are assembled, a groove with rectangular section in which the middle part 13 of the middle foot can fit together. Above and below below this middle part 13, the notches 11 and 12 of the leg 4 are delimited by two flat surfaces 18 and 19 which are parallel.
  • the intersections of these surfaces with the flat side faces of the part 13 are straight lines defining the direction of fitting of the foot 4 on the other two feet 5 and 6, which it maintains assembled in a cross.
  • the foot 4 can be prevented from dislodging by a simple wood screw passing through its middle part 13 and taken in the wood of the other two feet.
  • the upper part of the base 3, assembled with the seat element 1, forms in space a T which is absolutely rigid, so that there is no bending force at the level of the upper end of each leg assembled to the seat element 1. In fact, the bending moments which may exist in the legs are not transmitted through the assemblies. It follows that the base thus produced retains over time all its rigidity and stability.
  • the support in particular its base, can be assembled very easily and with little labor, which ensures a very low cost price compared to a base.
  • traditional If it is not glued, the base can easily be removed using a simple screwdriver, especially for delivery, shipping or storage. No particular qualification is required for reassembly of the support and there is no need for fittings other than screws.
  • FIG. 6 shows an example of a central leg 20 which can be used with the lateral legs 5 and 6, instead of the leg 4, to produce a support having four support points on the ground.
  • the foot 20 has a bifurcated shape in an inverted Y. It is formed by assembling two symmetrical pieces 21 and 22 glued together along a flat surface 23 located in the median plane.
  • the foot has a middle portion 24 identical to the portion 13 of the foot 4, below which it has two oblique legs 25 and 26, the lower ends 27 and 28 of which form two support points distant from each other and located below the front of the seat element as in an ordinary chair.
  • FIG 7 shows an advantageous embodiment of support provided with the base 3 described above.
  • each lateral foot 5 and 6 has on its front face a prominent rubber pad 29 allowing the chair to be placed on a table 30 in the position shown in the figure, the chair resting on the two pads 29 and on the front edge of the seat element 1.
  • this operation is much less tiring than with a traditional support that must be reversed to place its seating element on the table.
  • it is enough for a vertical translation with a slight tilting towards the front which is much less tiring and spares the furniture.
  • FIG. 8 is a view similar to FIG. 1 and shows an example of a two-seater seat composed by assembling two supports according to FIG. 1, connected by means of a horizontal piece of wood 32, the ends of which are placed on the crossed legs of the legs 3 of the chairs and are screwed to the middle leg 4. It is thus possible to provide seats with several seats, formed by a row of chairs.
  • Figure 9 shows an example of a "bar" type stool, consisting of a support and a base in which the cutting angle of the feet has been modified to increase the seat height.
  • the support according to the invention can be used for the production of all kinds of seats, chairs, tables, stools or pedestal tables.
