FR2803182A1 - SUSPENSION OF A MATTRESS HOLDER - Google Patents

Abstract

The mattress (1) rests on a mattress support, formed by a rigid rectangular plate (2), for example. This rigid plate (2) rests at its angles on four elastic balloons (3) which ensure the suspension of the support. The balloons (3) themselves rest on a base (4). The pole regions of the balloons (3) are housed in cavities formed in the opposite faces of the rigid plate (2) and the base (4) near the corners and are fixed there by gluing. The balloons (3) preferably have the shape of ellipsoids with a vertical axis flattened at the poles.

Description

I The invention relates to the field of mattress support suspension.

  In general, the mattress support has a box spring which rests in a bed frame or on legs. The bed base can be fixed or articulated. In the case where the bed base is fixed, it consists of a rigid frame which supports flexible slats or cleats on which suspension springs are mounted. This rigid frame can be fitted, at its angles, with feet resting on the ground, or it can rest

  in a bedstead or bed frame fitted with legs.

  In the case where the bed base is articulated, it is mounted on a frame

of bed resting on feet.

  Whether the base is slatted or sprung, it ensures

  occasional suspensions in association with the mattress.

  When the occupants of the bed are stationary, the elastic elements of the mattress and the box spring deform in such a way that the upper face of the mattress follows the shape of the bodies of the

  occupants, which ensures comfort.

  When one of the occupants moves, the elastic elements of the box spring and the mattress located under this occupant, are subjected to multidirectional variable forces whose horizontal components are transmitted step by step to the elements

neighboring elastic bands.

  Many of the elastic elements of the mattress and box spring are then subjected to vibratory movements which can be felt by a second occupant and cause him to wake up. This situation is particularly unpleasant for the latter. The same disadvantages also occur, when one of the occupants

  gets out of bed or sits on his bed.

  In these mattress supports, the bed frame or the box spring frame resting on the feet is by construction immobile by

report to the ground.

  The object of the invention is to propose a mattress support which can transmit the variations in the forces undergone by the mattress and the bed base to a suspension system external to the mattress and to the

  box spring, and thus minimize the drawbacks mentioned above.

  The object is achieved according to the invention by the fact that the support of

  mattress is mounted floating above the ground.

  More specifically, the invention relates to a mattress support comprising a rigid rectangular frame resting at its angles on feet, characterized in that the feet are constituted by

  elastic balloons ensuring the suspension of said support.

  The term rigid rectangular frame, used above, designates either a bed frame, a bedstead, or a slatted base, or a box spring, or a metal base, or even a

  rectangular panel on which the mattress rests.

  Thanks to the invention, the variations of the forces undergone by elastic elements of the mattress during a movement of an occupant of the bed, are transmitted via the support to the balloons. This is particularly the case with horizontal forces or sudden variations in vertical forces. The entire mattress then oscillates in unison with the bed frame. The movement of an occupant of the bed thus results in a

  rocking, conducive to the sleep of other occupants.

  It should be noted that with a bed comprising a suspension of the bed frame in accordance with the invention, the thickness of the elastic mattress elements can be greatly reduced, since their only function is to conform to the shapes of the bodies of the occupants of the bed, and the traditional slatted or sprung base can advantageously be replaced by a rigid plate resting on four balloons arranged under its angles. The following advantageous characteristics are also adopted: - the balloons have substantially the shape of ellipsoids of revolution around a vertical axis and slightly flattened at the poles; - The frame has on its underside, near the angles of the cavities arranged to receive the regions of the upper poles of the balloons; - The cavities are delimited by concave surfaces of revolution around the vertical axis; - The regions of the upper poles of the balloons are fixed in said cavities by gluing; -the pressure inside the balloons is adjustable; - The lower poles of the balloons each house in a cavity formed in the upper face of a base; - the base may be common to the four balloons and constituted by a rigid rectangular plate similar to the rigid plate replacing the traditional box spring. The flat ellipsoid shape of each balloon, the poles of which correspond in correspondence in cavities of the base and the frame, positively ensures a stable position of the mattress support. Following a horizontal movement of the mattress support, the axis of each

  balloon will oscillate around a vertical axis.

  The possibility of modifying the pressure in each ball allows the adjustment of the stiffness of each ball according to the weight

  and the morphology of the occupants of the bed.

  Other advantages and characteristics of the invention will emerge

  on reading the following description given by way of example and in

  reference to the accompanying drawings in which: Figure I is a perspective view of a bed fitted with a suspension according to the invention; Figure 2 shows in perspective and on a larger scale an angle of the bed of Figure 1; Figure 3 is a side perspective view of the bed of Figure 1; Figure 4 is a side view on a larger scale and partially cut away from an angle of the bed of Figure 1; Figure 5 is a section along the line V-V of Figure 4; and Figure 6 is a partially cut away view in the direction

oblique VI of figure 5.

  The reference 1 designates a mattress which rests on a mattress support consisting, in the example shown in the drawings, of a rigid rectangular plate 2 having dimensions slightly larger than those of the mattress 1. The rigid plate 2 rests on four elastic balloons 3, themselves resting on the corners of a base 4 which has substantially the same dimensions and the same configuration as the rigid plate 2. The base 4 has, for its part, four angle feet

5 which rest on the ground.

  Thus, the base 4 and the rigid plate 2 are spaced vertically and are connected at their angles by means of the four balloons

elastic 3.

  Each of these balloons 3 has the shape of an ellipsoid of revolution around a vertical axis 6, and is slightly flattened in the region 7a of the upper pole 7 and in the region 8a of the lower pole 8. Each balloon 3 is constituted by an elastic envelope 3a and is filled with air, gel, foam, oil or the like, to achieve the characteristics of a damped suspension and the internal pressure of each balloon 3 can possibly be adjusted or controlled by the user . The pressures inside the four balloons 3 can be identical or different depending on the pressure variation device used. It is preferable that the pressures of the balloons can be adjusted separately, in order to allow the adjustment of the characteristics of the springs equivalent to the balloons 3 according to

  the morphology of the occupants of the bed.

  As can be seen more clearly in FIGS. 4 to 6, the regions 7a and 8a of the upper 7 and lower 8 poles are housed respectively in cavities 9 and 10 formed in the faces opposite the rigid plate 2 and the base 4 near their angles. Thus, the region 7a of the upper pole 7 is housed in a cavity 9 formed in the lower face 2a of the rigid plate 2, and the region 8a of the lower pole 8 is housed in the cavity 10 formed in the upper face 4a.

from the base 4.

  The cavities 9 and 10 are delimited by concave surfaces of revolution around the axis 6, substantially complementary to the

  surfaces of regions 7a and 8a of poles 7 and 8.

  The regions 7a and 8a are fixed in the cavities 9 and 10 by gluing. The rigid plate 2 has in each of its angles and under its lower face 2a a protuberance I 1 in which the cavity 9 is formed. This protuberance 11 can be an integral part of the rigid plate 2 or be constituted by an attached part fixed under the

  rigid plate 2 by any appropriate means.

  In the same way, the base 4 has in each of its angles and on its upper face 4a a protuberance 12 in which the cavity 10 is formed. This protuberance 12 can be part

  integral with the base 4 or be constituted by an added part.

  In the embodiment described above, the four balloons

  3 rest on four protuberances 12 secured to the base 4.

  It is obvious that the base 4 could be deleted, without departing from the scope of the invention. In this case, the four balloons 3 would rest on individual bases each constituted by a protuberance 12

resting directly on the ground.

  For aesthetic reasons, the corners of the rigid plate 2 and the base 4 as well as the walls of the protrusions 11 and 12 are rounded. What matters is that the cavities 9 and 10 are dimensioned

  to prevent the balloons from escaping 3.

  As shown in Figures 4 and 6, the rigid plate 2 has on its upper face 2b a periphery 13 slightly raised. The technical function of this rim 13 is to allow a

  precise positioning of the mattress I on the rigid plate 2.

  In the example described above, the mattress support is constituted by a rigid plate 2. This arrangement provides ideal support for the back of the occupants of the bed. The flexibility of the bed is given by the elastic balloons 3. This mattress support could also be constituted by a rigid frame, taking up the periphery 13 of the rigid plate 2 and the protrusions 11, on which would be mounted a fixed or articulated bed base, with slats , with springs, or with straps, without going outside the frame

of the invention.
