Definitions
- the present invention relates to unsommier, that is to say the flexible part of a bed which rests in the frame also called châlit or on individual feet, and on which there is a mattress.
- This invention relates more particularly to bed bases comprising a rigid frame in which springs of the slat type made of wood or other flexible material are installed.
- the box spring formed of a wooden crate supplemented by underlying transverse bars furnished with vertical springs and covered with fabric, is gradually abandoned because of its volume, its weight and also because the characteristics of a part of the springs can evolve over time creating areas of permanent deformation.
- the slatted base usually comprises a frame composed of two panels (or bars) at the head and at the foot connected on each side by a lateral upright. Between these lateral uprights is installed a succession of slats usually wooden parallel to each other and to the head and foot panel, the advantage of such a box spring is that, these slats being independent of each other, the flexion at the shoulders and hips of the corresponding slats can be greater than that of the slats at the level of the head, waist or legs, thus ensuring more continuous support for the user's body, especially when the user is sleeping on their side.
- the two respective ends of each slat are usually encased in openings in the frame or in attached support pieces.
- a first solution consists in designing sophisticated fastening means such as those disclosed in the presentations DE 3 321 521 or CH 656 787, but which, due to their complexity make the box spring rather expensive to manufacture and therefore for sale.
- Another solution is to connect all the slats in the middle by a series of connections or a central rubber strap to limit the maximum bending of each slat which greatly reduces the advantage of such a box spring compared to the old springs .
- CH 658 891 it is suggested to split the slats vertically in the critical areas.
- the upper slats are still very rigid and the lower slats only very rarely come into operation unless there is a large build.
- the price of such complicated bed bases increases significantly.
- the manufacturers of beds seek to compensate for the inflexibility of the box springs by proposing mattresses specially designed for their products and produced from foam allowing more or less elaborate internal cellular structures.
- box spring An original type of box spring consists of a large envelope filled with water. But it turned out that such a box spring follows the movement of the body during sleep without making any correction. The sleeper can then unconsciously take a very bad position involving excessive efforts of one or more muscles. This sleeper then wakes up in the morning with aches. In addition, such sheets are difficult to heat in winter due to their thermal mass.
- the object of the present invention is to obviate the aforementioned drawbacks by proposing a slatted-type box spring in which the slats are independent and rather flexible so that each can flex sufficiently downward respectively so that each part of the body is supported with a uniform pressure or a desired pressure for the part of the body considered.
- This box spring must also include a simple means of control to avoid excessive bending leading to a poor position of the sleeper. This combination should minimize the importance of the mattress while ensuring real comfort and an optimum quality of sleep as a regeneration of physical and intellectual condition.
- the means of attaching the slats must be simple and effective: that is to say ensuring real support for the slats in all circumstances, while respecting their flexibility and also allowing the change of one or more slats by the customer himself, either to modulate the general flexibility of the box spring by replacing a slat with another cnolsie among various shapes and materials, or by modifying the height of the slat in the bed base according to his build.
- the design of this box spring must be such that the cost of production and therefore of sale is reasonable.
- a mattress with substantially horizontal slats comprising a head panel and a foot panel connected on each side by a lateral upright, a mattress in which one of the two ends of each slat is anchored to the corresponding lateral upright, the other end part of the batten passing through the opposite lateral upright in which it can slide.
- This bed base also includes means for limiting the maximum downward bending for each slat to a value varying in the longitudinal direction of the bed base.
- the means for limiting the maximum downward bending for each slat comprise at least one abutment cross-member underlying the slats, the ends of the cross member being respectively connected to the head panel and the foot panel, and the height of the upper face of the cross member varying in the longitudinal direction of the bed base.
- the means for limiting maximum downward flexion for each slat comprise, on the sliding end portions of the slats emerging from the lateral upright, abutment pieces formed in a position varying in the longitudinal direction of the bed base.
- the lateral uprights have an identical longitudinal series of openings, all the end portions of the same side of the slats being inserted in sliding fashion in the openings of the corresponding lateral upright and all the ends of the opposite side of the slats being embedded.
- in the openings of the opposite lateral upright and fixed either by means of a pin or screw introduced into the thickness of the upright and passing through the ends of the slats, or by means of an intermediate piece immobilized in the opening and having a central window in which emerge one or more transverse latches provided to engage in grooves formed in correspondence on the ends of slats.
- the downward bending stiffness of the batten is modified either by an increase in the thickness or the width of the middle part of the batten, or by at least one pair of vertical slots respectively located at the quarter and at the three quarters of the length of the slat, either by a series of notches formed along the longitudinal front or front edge of the batten.
- One or more slats can also have an arcuate or asymmetrical shape in the horizontal plane.
- the height in the bed base of each substantially horizontal slat varies in the longitudinal direction of the bed base.
- the lateral uprights can also have a network of identical openings in the longitudinal and vertical direction making it possible to install each substantially horizontal slat at a desired height and / or to install an additional underlying slat.
- FIG. 1 is a perspective view of a first embodiment of the bed base according to the invention
- FIG. 2 is a view in longitudinal section of the bed base according to FIG. 1,
- FIG. 1 is a view in longitudinal section of a second variant of the bed base according to FIG. 1,
- FIG. 4 is a view in longitudinal section of a third variant of the bed base according to FIG. 1.
- FIG. 5a and 5b are views in transverse and vertical section of an opening made in one of the side panels and in which a slat end slides.
- FIG. 6 is a perspective view of a second form of real isation of the salt base on the invention.
- the bed base comprises a frame consisting of two lateral uprights
- the lateral uprights 30 and 40 can be constituted by a fairly high vertical board of the order of 30 cm. As illustrated in Figures 1 and 2. these amounts may have an identical opening sequence and in correspondence 35 and 45 along a slightly oblique line rising at the feet. Referring to Figure 2. the openings 35 and 45 may rather follow a curve reproducing the shape of a human body lying on its side. More completely, the uprights can also have a network in the vertical and longitudinal direction of identical openings in correspondence 35 and 45 as illustrated in FIG. 4.
- the right ends 82 of the slats are inserted into the openings 45 where they are held in place by non-rusting brass screws or a wooden pin 80 inserted in vertical holes formed in the thickness of the upright 40, which screws or pins 80 pass perpendicularly through the ends 82 of slats.
- These screws or pins 80 can themselves be held in place by a rod not shown and attached by screwing or gluing on the upper edge of the upright 40.
- Another method of anchoring may include an intermediate piece whose outer periphery corresponds to that of the opening 45 in which it is immobilized. This intermediate piece has a central window in which emerge one or more transverse latches provided to engage in grooves formed in correspondence on the ends 82 of slats.
- the end part 84 of a slat passes through the opening 35 in which it is intended to slide.
- the opening 35 is in the form of a slightly oblique channel towards the inside of the bed base and of height greater than the thickness of the slat part 84. Thanks to this configuration, the external slat part 84 is in no way jammed when the central part of iatte lowers but on the contrary it is quite free to slide.
- the coefficient of friction between the slat part 84 and the wood making up the upright 30 can be reduced by means of a transverse roller 32.
- the opening is formed by an insert 36 also having an oblique channel oriented towards the inside of the box spring. This part is made either of a harder wood or of plastic or of teflon which significantly reduces the coefficient of friction between it and the end part of the slat 84.
- the slats lining this box spring according to the invention are intended to be rather flexible and flexible without however being too soft. These characteristics are obtained by combining the material used: wood, laminated wood or composite material with their shapes.
- the slat 60 has a continuous rectangular section over the entire length and can be horizontal or slightly arched upwards. Its flexibility can be slightly modified by vertically sawing one or more pair of longitudinal slots 63 substantially a quarter and three quarters of the length thus increasing the flexibility of the slat 62.
- the height arrangement of the slats can be adjusted according to the type of sleep of the user.
- the arrangement of the slats in an oblique plane as illustrated in FIGS. 1 and 2 is more suitable for a person sleeping rather on the back or on the stomach, while the arrangement illustrated in FIG. 3 will be more pleasant for a person who tends to sleep on their side.
- this possibility of arrangement of slats makes it possible to preform the bed base to the configuration of the body during sleep.
- the network of openings 45 as illustrated in FIG. 4.
- a first upper sheet in an oblique plane consisting essentially of slats 60 very flexible and a second lower ply consisting of slats 61 firmer and arranged in a transverse curve reproducing the shape of the human body on the side.
- a second lower ply consisting of slats 61 firmer and arranged in a transverse curve reproducing the shape of the human body on the side.
- the Maximum downward flexion should be limited for two reasons: to prevent a part of the body from sinking excessively, which can lead to torsion of the spine during sleep, and, on the other hand, to prevent the extreme part of the batten 84 does not come out of orifice 35.
- This maximum flexion limitation is precisely the role of crosspieces 50 or 55, the upper face of which also reproduces the profile of a human body lying on its side as well illustrated in FIGS. 2 , 3 and 4.
- the crossmember 50,55 Starting from the left, where the head is intended to be located, the crossmember 50,55 first lowers down to provide space for the shoulders and then rises slightly upwards to support the torax meme s waist and go back down substantially in the middle to make room for the hips before going up very slowly and to the right to slightly elevate the feet.
- the upper surface of the cross-member 50 or 55 is covered with an elastomer layer 90 or filled with a series of rubber pads 92 correspondingly under each slat 60.
- FIG. 6 A second embodiment of the bed base according to the invention is illustrated in FIG. 6.
- the means for limiting the maximum downward flexion of the slats essentially consist of stop pieces 85 formed on the part emerging from the upright 30 from the end of the slat 84, These abutment pieces 85 are located at a distance from the upright 30 which is a function of the maximum flexion granted to the corresponding slat. As best illustrated in Figure 5a.
- these stops 85 are preferably corners oriented towards the upright and cut into the mass or attached by gluing and screwing. Such a wedge shape has a better bearing surface in the orifice 35.
- the thickness of the mattress can be substantially reduced, which makes its handling all the more easier. and its maintenance.
- the free spaces located under the head and under the feet can be usefully taken advantage of by drawers 100 and 105 as illustrated in FIG. 4 which are pulled or rotated.
