Definitions
- the invention relates generally sommieres.
- the invention more particularly relates to a bed base comprising a frame frame, and a sleeping surface for supporting at least the body of a person.
- Said sleeping surface has at least a central support portion of the gluteal, fixedly mounted relative to the frame, on either side of which extend respectively a support portion of the knees and a supporting portion of the back.
- Said knee support and back support portions are each adapted to be moved between a lowered position on the frame and a raised position relative to the frame.
- the sleeping surface does not allow to marry in a regular manner the profile of the mattress and therefore the body of the extended person, through the mattress, on said sleeping surface.
- Such a design of the sleeping surface is detrimental to the comfort of the person.
- An object of the present invention is to provide a bed base for which the sleeping surface is liftable while maintaining in the raised state a profile in the form of a regular line, that is to say without broken pan, so as to marry correctly the profile of the body of the person lying on the sleeping surface via the mattress.
- Another object of the present invention is to provide a bed base with a lifting surface whose profile has a regular curve line regardless of its configuration, raised or lowered, while providing good support for the body parts of the person, especially at the back and knees.
- each longitudinal blade of flexible connection plays the role of a spinal column connecting the rigid panels that form the vertebrae of said column.
- the or bendable longitudinal blades which connect the corresponding rigid panels together, form flexible joints without moving rigid parts, this which allows them to present a regular continuous curvature when the rigid panels are moved relative to each other.
- the presence of the or bendable blades between the panels avoids the appearance of broken sections at the curve formed by the profile of the sleeping surface in the raised position of the support portions of the knees and / or back. Indeed, the relative displacement of the rigid panels between them is accompanied by the bending deformation of the bendable blades, about an axis parallel to the plane of the frame and orthogonal to the longitudinal axis of the frame, which allows the surface of Sleeping the box to marry at best the curvature of the mattress and thus the morphology of the person lying on the mattress.
- the sleeping surface has a regular profile which corresponds to a curve whose derivative of order 1 is continuous, allowing to the sleeping surface to effectively marry the profile of the mattress and the person to enhance comfort.
- the sleeping surface in the form of rigid panels, the sleeping surface also provides firm support for the different parts of the body of the person lying on the sleeping surface, both in the lowered and raised position, while allowing the sleeping surface to have different lines of regular curvature depending on the morphology of the extended person and his position on the sleeping surface.
- the design of the support portions of the back and knees in the form of series of elements formed of panels provides for each of these support portions, a lower surface, respectively upper, formed by the lower surfaces, respectively upper, panels that form said support portion, which is close to the neutral fiber of said support portion
- the panels have a small thickness compared to their width and length dimensions.
- the lower faces, respectively upper, of the panels that make up said portions deviate slightly from each other, which reduces the appearance broken flanks along the sleeping surface.
- the panels have a thickness less than or equal to 5 times the width of the panel.
- the width of a panel corresponds to the size of the panel taken along the neutral fiber of the sleeping surface (please complete).
- the coating surface also comprises at least one so-called end panel, extending the a knee support portion for forming a foot support portion, said end panel being connected to the other panels of the sleeping surface by said at least one longitudinal bendable connecting blade which connects at least the panels of said support portion of the knees at the central portion fixed gluteal support.
- said back support portion and said knee support portion are each connected to the central gluteal support portion by at least two, preferably four, longitudinally displaceable connecting blades parallel to one another and arranged at a spacing from one another. on the other in the direction of the width of the sleeping surface.
- At least one of the longitudinal strips of flexible connection is attached to at least a portion, preferably each, of said panels, preferably on the underside side of the panels, preferably by screwing.
- at least one of the longitudinal strips of bendable connection is housed at least partially in the thickness of said panels, preferably near the neutral fiber of said panels.
- At least a portion of the panels which form said knee and back support portions are of width, taken along the longitudinal line of the sleeping surface, less than the width of the fixed central portion. gluteal support.
- the or at least one of the longitudinal strips of flexible connection which connects the knee support portion to the fixed central support portion of the gluteal shape with the or at least one of the longitudinal blades of flexible connection which connects the support portion of the back to the central portion fixed gluteal support a piece in one piece.

- the sleeping surface also comprises a so-called end panel, extending the support portion of the knees to form a foot support portion
- each longitudinal edge of the coating surface is coated with an elongated elastically deformable element, called rod, for masking said longitudinal edge.
- Such a ring provides a regular profile visually on each side of the sleeping surface, regardless of the curvature taken by the sleeping surface.
- Said ring masks any apparent gaps between the panels that would be visible along the sides of the sleeping surface in the absence of said ring.
- the application of a ring on each of the lateral edges of the panels which form the coating surface is particularly advantageous for obtaining a line of regular curvature of the coating surface, because the panels being of small thickness, compared to their dimensions width and length, the upper and lower longitudinal edges of the rod are close to the average line or neutral fiber formed by said or bendable blades that connect the panels together, which limits the risk of tearing of the rod, during the curvature changes that the sleeping surface undergoes.
