Abstract: The present invention relates to a bed system which comprises a mattress supporting structure. The bed system comprises a height adjustment system which comprises at least one rotatable multi-angular transverse beam comprising a plurality of transverse beam sides and an eccentric rotation axis which is accessible from outside said outer frame. The height adjustment system further comprises a rotation imparting member which is accessible from outside the outer frame and provided for rotating said at least one rotatable transverse beam about its eccentric axis. Said rotation imparting member is displaceable between a first and a second position. The first position is provided for rotating said at least one rotatable transverse beam about its eccentric axis and said second position is provided for blocking said at least one rotatable transverse beam in a desired height position with respect to said outer frame.
Abstract: This invented multiple-phase dynamic cushion comprises a frame, at least a driving source, at least a transmission assembly, and clusters of plural strips interleaved in parallel. Taking a two-phase embodiment as an example, the two-phase strips interleave with each other, in parallel, to form the cushion's surface and alternate their tensions in turn; when one phase's strips periodically tighten to support the user's body, the other phase's strips will loosen, allowing the user's body covered by the loosened strips to take a rest, averting a pressure-ulcer risk. The driving source is energized by an altering energy, making the two strip groups alternate in loosening and tightening states periodically in turn. This invention can be converted into a portable dynamic chair when the four holes on the bottom of its four corners are inserted with legs; it can also be converted into a dynamic support for a lying human body.
Abstract: Stimulation actuators that exert any desired movements on the underspringing arrangement. The underspringing arrangement has lifting members (11) that are mounted elastically by means of elastic elements (14). The elastic elements (14) are arranged such that at least a main direction of work extends at an angle with respect to the direction of the movement of the lifting member. In this way, the lifting member (11) can have a particularly low overall height. The supporting surface of the underspringing arrangement can be moved up and down by the lifting member (11) and the elastic element (14), thereby permitting an individual stimulation and movement of a person lying on the mattress.
Abstract: A lying surface for a bed, especially for a healthcare and/or hospital bed, comprises support elements (22) and at least one electro-mechanic lifting unit (20) for lifting and lowering one of the support elements (22) relative to a bearing element (62) of the support element (22). The at least one lifting unit (20) comprises a housing (24) with an electromotor (32) having a drive shaft (34), a transmission (38) and a lifting member (50) supported at the bearing element (62) of said one support element (22). The lifting member (50) is adapted to be rotated by the transmission (38) and to be moved both up and down during a rotary movement of 360°.
Abstract: A support base for a bed mattress (3) including a housing (1) having a plurality of transverse slats (2) for supporting said mattress wherein one or more of said slats are individually adjustable relative to said base to provide calibrated positive or negative height adjustment for each slat, characterized in that said height adjustment is provided by a means which is operable external to said housing.
Abstract: An apparatus in the form of a bed or chair for providing relaxation therapy and prevention of decubitis sores is distinguished by the use of flexible beams of the nature of leaf springs. Instead of being lifted up and down by rather complex apparatus only a single shaft carrying cams is provided which acts on the leaf spring-like beams to flex them upwardly and/downwardly to provide the required action. Preferred cams provide no lifting action but only intermitted depressing action of these beams which reduces vertigo and nausea effects and can be slid onto a cam shaft in any one of a multiple alternative angular positions. This enables selection of the travelling wave action for relaxation therapy and of the decubitis preventing action.
Abstract: A bed for patients that require periodic movement of their body parts. The bed includes a rectangular frame with panel members transversally disposed. Each panel member is supported by a pair of eccentric members that in turn are rigidly mounted to two spaced apart shaft that are parallel to each other. The shafts are imparted a rotational force by a motor assembly that generates a reciprocating movement that is translated to a rotational movement applied to the shafts. The eccentric members cammingly engage the underside of the panels, and they are divided in two sets of eccentric members that are aligned with respect to each other so that each set is composed on non-adjacent alternate panels that are lifted when the panels of the other set are brought down.
Abstract: A patient bed including castors (1) resting against the floor, legs or a base frame, and a bed framework (2) and a mattress (3), the mattress further including a number of elongated mattress elements (3', 3", etc.), aligned parallel in the longitudinal direction of the bed, and the bed framework being made of a framing of the patient bed to which framing are attached tubes (8) or similar slats, aligned parallel with the mattress elements of the bed and forming an essentially horizontal plane in which each tubular slat is aligned in the crosswise or longitudinal direction of the bed to essentially coincide with a furrow adapted between the mattress elements. The invention is implemented so that the patient bed is provided with means (5-7) for moving the mattress (3) essentially in the vertical direction between a first plane defined by the tubular slats and a second plane below the first plane and for stopping the mattress at a desired elevation between the two planes.
Abstract: A sickbed, comprising: a first bed frame, provided with a plurality of fixed bed planks of mutual distance to support the patient's body and allow him to sit up or lift the legs, thus changing his posture; a second bed frame, vertically movably mounted below the first bed frame; a plurality of movable bed planks, which are mounted on said second bed frame, at a suitable height above said second bed frame, keeping certain distances from each other and being placed in gaps between said fixed bed planks; a first driving device to drive the second bed frame's movement up and down; and a second driving device to drive the first bed frame. Its improved parts include two lateral turning frames to help the patient to turn around, each further comprising a shaft and a plurality of parallel support planks of mutual distance, which are mounted on said shaft, placed in gaps between the fixed bed planks and the movable bed planks, and are movable in a rotary movement as driven by said shaft.
Abstract: A convertible wheel chair/bed for paralyzed invalids comprises a support on which the invalid rests, the support comprising a plurality of support segments which define a support surface. The support segments can be moved simultaneously so the parts of the skin which were in contact with some support segments are relieved from pressure and exposed to air so that perspiration on that portion of the skin can evaporate, while other parts of the skin of the invalid are engaged and supported by support segments.
Abstract: Support structure consisting of a plurality of elements for chairs, beds and the like, which may be moved individually or in groups, in which the mechanism which performs the movement of the generic element downwards and successively upwards is composed by an articulated parallelogram having one side integral with said element, that side presenting a small wheel which is in rolling contact with a cam fitted to a shaft supported by a lug integral with the frame.
Abstract: A bed having an array of cylindrical support members supported by a main frame to support a mat, such that the support members are spaced apart from each other in the transverse direction of the bed and such that the support members are rotatable, and a device for rotating the support members in rolling contact with the mat, for changing areas of contact of the mat with the support members to thereby change areas of contact of the user with the mat for promoting blood circulation in a portion of the user in contact with the mat.
Abstract: A pressure relief bed which supports the body of a patient on two racks, each of which carries a series of parallel, closely-shaped padded slats. The slats on one rack are interposed between the slats on the other rack. The structure includes means for alternately moving one rack and the slats thereon out of contact with the patient's body while the other rack, and the slats thereon, support the body.
