Definitions

  • This Patent of invention refers to a bedstead formed by a succession of transversal springs fitted on a frame structure. Apart from others which we shall be seeing later, this bedstead offers the special feature of its springs being made from fibre reinforced plastic materials.
  • the spring bedstead As a result of the research, work and tests carried out, the spring bedstead, the subject matter of this Patent, was obtained, in which three fundamental components are distinguished, made up, in fact, of the section itself, which is actually the spring, the bushes for fitting them into the bedstead's frame and supplementary caps perfecting the spring-to-bush assembly which, in turn, contribute towards the mattress being stable on the bedstead.
  • the section which is the spring itself, is characterized by having an inverted "U" shaped cross section and short vertical arms compared to its broad horizontal stretch, and said vertical arms, at a point nearly halfway up, converge inwards with respective 45° angles providing the section with bevelled longitudinal edges; this section can be obtained from flat, crimped, woven, combed or braided fibres or a combination of them; by subsequent injection onto them in a suitable press-mould of any type of thermostable plastic material such as ortho- and isophthalic poliesters or any other equivalent, either alone or with various organic and inorganic charges such as calcium phthalate, calcium carbonate, talc or others and, during the process, adding small amounts of other materials such as fabrics, threads, plastic films with a minimum thickness or paper which, apart from influencing the section's behaviour, participate in the outside, decorative finish of the spring; proportions of 70% fibre to 30% isophthalic resin or plastic are foreseen and, to the effects of the deflection required in the spring's
  • the invention also provides for the possible addition of two narrow, longitudinal projections on the spring's functional surface, as a continuation of the bevels of its two short side faces. These projections are angular in cross section and define two thin grooves which lead to perfect adaptation of the mattress to the bedstead and prevent, it sliding, as well as respective reinforcing ribs in the centre of its inside/ underneath part.
  • the invention's second component relates to the bushes which fit into the bedstead's frame and house the ends of the springs, protecting them from friction and wear, since frames are usually metal and movements in the springs as a result of their bending capability must be prevented from ocurring on the frame's metal edges.
  • these bushes have a slotted body exactly matching the spring, the end of which they receive and, at their mouth facing towards the inside of the mattress, their end side faces and bevelled edges noticeably emerge and are prolonged in thick side lugs located in a plane perpendicular to the body in an approximately square shape but with their outside vertices curved. This curvature is more marked at their respective upper vertices.
  • the supplementary caps also made in plastic, contribute towards improving the anchoring of the springs to the frame and towards stabilizing the mattress on the bedstead. They ire essentially shaped by a hollow body without a bottom, with a truncated parabola in plan view decreasing in height from the widest part, where it matches the bedstead's frame, to its opposite end, parallel and narrower, in which the height of this supplementary body practically matches that of the springs.
  • these caps At their narrowest end, which faces towards the bedstead's longitudinal centre line, these caps have a mouth coinciding in shape exactly with the section of the springs and, from this mouth, three ribs begin and extend in parallel fashion towards the inside of the cap, slightly increasing their height as the cap itself does, acting as guides and adapting to the shape of the springs which are to be located inside them.
  • the two side ribs which are the highest and are located on both sides of the spring, are provided on their inside edge with small longitudinal projections emerging towards the centre line of the cap and bevel shaped to hold the spring when pressure is exerted on it when fitted in the bedstead.
  • the aforesaid three ribs do not reach the widest end of the cap so as to shape a clear space between them and small side pieces which, at this widest end of the cap, close it off and allow it to house and hold the spring receiving bush side lugs.
  • the springs protected by the Patent are shaped from a special section adopting an inverted "U" shape cross section with its short, vertical arms converging inwards towards a broad horizontal stretch.
  • the proportions of these sections vary both as a function of the size of the bedsteads on which the springs are fitted and as a function of the place each spring occupies in the bedstead's frame, since bedsteads are known where their centre springs pertaining to the areas in which the bedstead has to support greaters stresses are noticeably wider than springs located in areas near the bedstead's headboard and footboard.
  • the Patent also provides for the section making up each spring to be given a slight longitudinal curvature which determines the deflection defining its elastic capacity.
  • each spring within the bedstead's framework withstands a pressure exerted by the weight of the users and, thanks to this pressure and the springs's elasticity, the spring undergoes a deformation of its initial design which is reflected both in the arc of its longitudinal curvature and in the parallelism of the short vertical sides given by the "U" cross section, the sides of which tend to diverge outwards in order to absorb the bending stresses supported by the spring, whilst totally or partially recovering its original shape as soon as the pressures being received are removed or modified by virtue of the spring's intrinsic elasticity.
  • this Patent has provided for simple spring elasticity and strength regulating elements, each of which is made up of a totally rigid piece in a general elongated rectangular prismatic shape, which offers the special feature of having a transverse channel or hollow all the way through, also rectangular in cross section, defining openings in its long sides. Like the rest of the hollow, these side openings exactly match in size those of the section of the spring to which the regulator is tightly fitted in order to facilitate its being moved along the spring. On its shortest ends, this regulator thickens for reinforcement on both sides and thus defines concave-knurled arching effects on the outside surface which facilitate the regulator's manual sliding along the spring.
  • regulators have + and - signs engraved on their top face, which is the most visible. These signs are duly aligned in the vicinity of one of its ends and when these regulators are fitted on a bedstead spring, the + sing appears on that side of the regulator facing towards the bedstead's centre whilst the - sign is located on the side nearest the bedstead's sides.
  • Fig. 1 shows us two different sizes of the section making up the springs as envisaged in the patent.
  • the sizes of this section will naturally adjust to the requirements and features of the bedstead it is intended to make in each case.
  • Fig. 2 represents the bush in which the spring ends fit in front elevation, plan and rear view, as well as a detail in perspective of this piece, making it easier to understand.
  • Fig. 3 shows a section of the same bush through A-A′ in Fig. 2.
  • Fig. 4 shows another section of the same piece cut through B-B′ in Fig. 2.
  • Fig. 5 shows two views of the supplementary cap seen in elevation from its widest end and seen in plan underneath without a bottom.
  • Fig. 6 is a section view of the same cap through C-C′ in Fig. 5.
  • Fig. 7 shows two views of the cap itself enabling us to see both its external configuration and its internal structuring.
  • Fig. 8 and Fig. 9 give us a top and underneath view of the three basic bodies making up this patent, i.e., spring, bush which receives one end of same and supplementary cap as they are all fitted and mounted on a frame to make up the bedstead assembly, which is not shown completely in the drawing as it is deemed unnecessary, since it would be no more than a mere repetition of what is defined and represented in these drawings.
  • Figure 10 represents in perspective a portion of a spring made in accordance with the Patent.
  • Figure 11 is a schematic representation of a spring seen from the side to show us its slight longitudinal curvature giving it its deflection.
  • Figure 12 shows us a view through A-A′ of Figure 11 when the spring is at rest.
  • Figure 13 is another similar view showing the spring when under pressure.
  • Figure 14 shows us a plan and elevation view of a spring strengthening regulator.
  • Figure 15 shows the same item in perspective.
  • Figure 16 shows a cross section through a spring coinciding with the positioning of a regulator.
  • Figure 17 consists of a view in top perspective of a spring with its regulators, fitted onto a bedstead frame.
  • the springs 9 are formed from an inverted "U” shaped section with short vertical arms converging inwards to form the bevel 1 joining the horizontal stretch 2 which is the spring's functional surface.
  • the invention has slight longitudinal projections 3 on this horizontal stretch 2 as can be seen specifically in Fig. 1. Their sole purpose is to improve the mattress's seating on the bedstead.
  • the figures also show us the special arrangement of the spring receiving bush 11 in which its slotted body 4, shaped to the shape of the springs, and the lugs 5 which emerge on both sides of its mouth can be seen.
  • the cap 12 which, by means of its interior ribs 6 fits with the spring 9, is also shown.
  • the spring is secured onto said ribs via the longitudinal projections 7 which emerge slightly at their bottom edge and are bevelled to face towards the cap's centre line. These projections are located on the two side guide ribs 6.
  • the drawings also show us how the springs 9, shaped in their initial structuring with deflection f, deform the parallelism of their narrow vertical sides in the manner as shown in lines BC-DE and B′C′-D′E′ when receiving pressure effects. Such deformation is conditioned and made practically impossible thanks to the action of the rigid regulator elements which fit their full length hollow space 13 to the cross section of the springs 9.
