Definitions

  • This invention relates to the field of beds the rest surfaces of which can be rotated through variable angles but are not subjected to excessive loads, for example sun beds.
  • Beds are known formed from a basic support structure which supports the weight of the body and an auxiliary support structure which supports the weight of the head and/or legs.
  • auxiliary structures are generally rotatable to obtain various inclinations.
  • the structure usually used for sun beds consist of a rigid frame for supporting the extended legs and the body, and carry at one end a rotatable surface or head rest for supporting the shoulders and/or head.
  • This rotatable surface is hinged to the fixed structure in the manner of a 1st order lever and the extent of its inclination is determined by interposing a spacing strut pivoted on the end of the fixed frame and elastically removable when not required for the purpose.
  • the obtainable inclination is only that consequent on the length of the strut and its distance from the pivot.
  • the end of the head rest frame projects beyond the fixed structure by a length equal to the arm length required when in the operating position to enable the removable strut to engage against the fixed frame.
  • An object of the present invention is to provide a sun bed having its end rest surfaces rotatable in such a manner as to obtain a multiplicity of inclinations.
  • a further object is to provide a sun bed which can be folded to minimum overall dimensions such as to enable it to be easily contained in an automobile boot.
  • a further object is to provide a sun bed which can perform a multiplicity of supplementary functions.
  • a further object is to provide a sun bed having its end rest surfaces inclinable either directly or indirectly.
  • the sun bed according to the invention is formed from a fixed structure 1 for supporting the body and provided with traditional pairs of hinged feet 2 and 3 fixable to it by normal pins 4 and articulated tie bars 5.
  • said pairs of legs 2 are provided with wheels 6 of fixed or caster type.
  • the bed can have two end rest surfaces 7 and 8 able to be rotated as far as vertical positions, it is also suitable for use as a trolley for transporting bulky nautical equipment 9 and other beach accessories 10 from the automobile to the beach.
  • Positioning the end rest surfaces vertically (7, 8′) enables the transported nautical equipment (9) to make contact only with the edges 7A and 8A of the rest surfaces 7 and 8, and not with the fabric-covered surface on which parts of the body lie. This advantageously allows transportation of rigid objects (9) which are not totally clean.
  • the inclinability of the two surfaces 7 and 8 also allows a variable distance D to be obtained between the supports or edges 7A, 8A which makes it adaptable to the type of equipment or object transported.
  • a bed with its end rest surfaces positioned along 7′ and 8 ⁇ can be lifted by directly gripping these ends, either to use it as a stretcher, or more simply to take it up or down steps.
  • the articulated joints which provide these properties are indicated diagrammatically by the reference numerals 11 and 11b, but are more clearly shown in Figures 2, 3, 4 and 5.
  • the joint 11 can be operated indirectly by a cable, whereas the joint 11b is suitable for direct operation and thus particularly for adjusting the surface which is to support the legs.
  • the joint 11 shown in Figures 2 and 3 is composed of a toothed sector 12 fixed to a tubular structure 13 by usual means (insertion, rivets, pins), and comprising a series of teeth 14 forming cavities 15 disposed circumferentially about an axis 16.
  • the axis 16 is common to a pin 17 and to working holes 18 and 19 pertaining to the articulated parts 7 (or 8) and 1 respectively.
  • the ends 8E (or 7E) of the frame for the surfaces 8 (or 7) are each secured by their own joint 11 and are therefore provided with a pair of teeth 20A and 20B forming a cavity 21 arranged to coincide with the cavities 15 of the sector 12 during its rotation about the axis 16.
  • This pivoting is provided in a region intermediate between that in which a spring 26 urging the edge of the end 8E (or 7E) acts and that containing the pin 22, so that said U-section 23 behaves as a 1st order lever.
  • the locking pin 22 is always urged into the interior of the aligned cavities 15 and 21, to prevent any angular movement between the frame 1 and the rest surfaces 8 (or 7).
  • the locking pin 22 is extracted from the cavities 15 and 21 by a lever movement consequent on compressing the spring 26. This can be done either directly by pressing the end of the U-section 23 (for example at the dished seat 23C for housing the spring 26), or indirectly by using auxiliary means.
  • lever-cam 27 pivoted on a pin 28 about holes 29 in the U-­section 23 and projecting therefrom through an aperture 30.
  • the end 27A of this lever-cam can thus be operated by a traction cable 31, the operating end of which can be located, with the cooperation of usual deviation pulleys, in the most comfortable and accessible position.
  • the operating end of the cable 31 is connected to the operating end of an identical cable pertaining symmetrically to another joint 11 associated with the end (7E, 8E) on the other side of the support frame for the surfaces 7, 8.
  • the lever-cam 27 is associated with a return spring 32 which prevents it projecting from the U-section 23 but at the same time allows it to move through a distance e before engaging the edge 7Z in order to make available a larger operating arm on pulling the cable 31.
  • Two rest surfaces 8b and 1b are hinged to each other on an axis 31.
  • Projections 32A, 32B, 32C on the frame for the surface 1b are traversed by a shaft 33 rigid with the surface 8b and with the projections 34A and 34B on the frame for this latter surface.
  • the projections 34A and 34B are fitted with insertion-coupling wheels having flat toothing of rounded profile 35 and 36 conjugate with other similar insertion-coupling wheels 37 and 38 rigid with the projections 32A and 32C respectively.
  • wheel pairs are kept in their disengaged position by the separating action of springs 39 and 40 wound about the shaft 33. They are made to approach each other and thus mutually engage by the action of a cam 41 pivoted on the end of the shaft 33 on an axis 43 and operated by a lever arm 42.
  • the axial engagement and disengagement movement of the pairs of insertion-coupling wheels 35, 37 and 36, 38 can be obtained not only by a cam of the type 41 but also by cams having teeth in the form of opposing inclined planes such as those indicated in Figure 5.
  • this latter is fixed (for example rigid with the frame 1) and the cam 45 is mobile and operable in the direction of the arrow 47 to cause its torsionally free pin 48 to move axially towards the left, it is apparent that this operation (arrow 47) results in engagement and disengagement of the insertion wheels 35, 37 and 36, 38 shown in Figure 4, this being again obtained with the cooperation of return springs 48 urging in the appropriate direction.
