An extendable arm (30) is formed by a plurality of cross units (31) arranged in one direction and pivotally coupled to each other, and each of the cross units is formed by two rigid members (31a, 31b) that are pivotally coupled at a central coupling point (c) so as to cross over each other to form an X-shape. In order for the extendable arm (30) to follow a curved-line path when being extended and contracted, each of the rigid members (31a, 31b) has such a curved shape that coupling points (d, e) at both ends of the rigid member are shifted toward one side from a longitudinal axis passing through the central coupling point (c).

The present application provides a detachable side table which can be detachably mounted at a side of a chair or a bed. The detachable side table includes a tray provided with an article-carrying platform, and a bracket fixedly connected to the tray in a detachable manner, and the tray is connected to the chair via the bracket. In using the detachable side table provided by the present application, the tray is fixed to the chair or the bed by the bracket, such that a user can place articles onto the article-carrying platform of the tray. The detachable side table provided by the present application can be used cooperatively with a conventional chair or bed. When the detachable side table is used cooperatively with a conventional folding chair, the folding chair may have more functions.

Es wird ein Bett mit einem Gestell (1), mit einem im Gestell (1) verstellbar gelagerten, wenigstens einen Stelltrieb (5) aufweisenden Einsatz (2) und mit einer durch Steuerschalter ansteuerbaren Steuereinrichtung (6) für den Stelltrieb (5) beschrieben. Um vorteilhafte Konstruktionsverhältnisse und eine einfache sichere Handhabung zu schaffen, wird vorgeschlagen, daß die Steuerschalter eine mit einem Betteil verbundene Folienschaltereinrichtung (7) aufweisen.

An object of the invention is to provide a bed which can surely detect the positional shift and heartbeat vibration of a bedded person while suppressing the increase of the cost and the degradation of the comfortability of a bed, and to provide a bed and an in-bed state detection method which can prevent the undesirable caught at the time of elevating the bed.

In order to detect the shift of a bedded person, a ratio of intensities between output signals from first pressure sensitive sensor 21 and a second pressure sensitive sensor 22 each having a cable shape is obtained. These sensors are disposed along the lying direction at the both end sides of a bedding surface 15a on which a bedded person lies, respectively. When the ratio is in a range of a predetermined shift state set in advance, it is determined that the positional shift of a bedded person on the bedding surface 15a occurs.

Further, a low-repulsion urethane layer is provided within a bed pad thereby to detect the heartbeat vibration. Furthermore, the elevational driving of the panel portion is controlled in accordance with the output form the pressure sensitive sensor disposed on a bed.

Es wird eine Vorrichtung zur seitlichen Halterung einer Matratze auf einer Matratzenauflagerung zur Verfügung gestellt, welche einen platzsparenden Transport eines Bettrostes erlaubt und schnell und einfach an eine Vielzahl unterschiedlicher Rahmensysteme angeordnet werden kann, was dadurch erreicht wird, dass die Vorrichtung aus einem Befestigungsteil (3) zu ihrer Festlegung an einem seitlichen Teil der Matratzenauflagerung besteht sowie aus einem Matratzenhalter (1) und einem Raststück (2) und dass das Befestigungsteil (3) mit einer Aufnahme (4) für das Raststück (2) versehen ist.

The device comprises a pivot pin (6) integral with one bed component (7) having a substantially elliptical transverse section defining minimum dimensions (d) and maximum dimensions (D). A seating (8) defined by an engagement element (9) carried by a second bed component (10) has a circular profile the diameter (D') of which is equal to the maximum dimensions (D) and broken by a substantially rectilinear access opening (14) having substantially the same width (d') as the minimum dimensions (d). The pivot pin (6) can be removably engaged in the seating (8) in a radial direction and according to a predetermined orientation in order to connect the first component (7) to the second component (10) in such a way as to enable a rotation of predetermined amplitude.

Disclosed is a bed for promoting growth and relaxing joints and muscles. The bed for promoting growth and relaxing joints and muscles according to one preferable embodiment of the present invention may comprise: a bed mattress part; and rotation roller parts which are installed on both sides of the mattress part so as to support a user's upper body and lower body, and which move the user's upper body and lower body in the direction of the end of the head and in the direction of the end of the toes with respect to a pelvis region so as to stretch the body, thereby promoting growth and relaxing the joints and muscles. Accordingly, the present invention has effects of promoting growth, in the case of infants, children and teenagers, by providing an artificial stimulus of stretching not only joints in which physeal plates are positioned, but also the whole body in a sleeping state; and in the case of adults whose growth period is complete, recovering joints which have been pressed due to activities such as standing for a long time or carrying heavy items, promoting blood circulation by stimulating the skin, and relaxing the muscles.
