Definitions

the present invention relates to a device for setting the hardness of individual support elements of a support device, in particular a lower mattress.
the invention has for its object to provide a device of the type mentioned, which offers an advantageous adjustment of the spring rate.
a device for setting the hardness of individual support elements of a supporting device, in particular a lower mattress, with a vertical to a Axle between a first position with a first spring stiffness of the single support member and a second position with a second spring hardness of the single support member rotatable Härteinstellelement, in particular Härteinstellring, wherein at least two Härteinstellelemente are interconnected via a push rod such that the two hardening elements rotate together and in the same direction.
an actuating arm is provided on at least one hardness setting element. With this actuating arm, the hardness setting element of the associated individual support element is adjusted. At the same time, a corresponding hardness setting of the other individual support elements takes place via the push rod.
actuation arms are respectively provided on the two end-side hardening setting elements.
the hardening adjustment can take place from both sides, which is advantageous in particular with a lower mattress of a bed standing on a wall.
the hardening elements have cams which serve to support spring arms of the respectively associated adjusting element.
a smaller number of spring arms may be supported via cams in the first position of the Härteinstellvorraum than in the second position.
the spring arms in the first Position be supported by cams of a lower height than in the second position.
the effective in the first position cams may have a lower hardness than the effective in the second position cams. In this way, a different hardness can be set advantageously with simple means.
the individual support elements 1 of the illustrated portion of a lower mattress are mounted in a row on a bar 2.
Other such strips 2 with individual support elements 1 may be provided distributed over a lower mattress.
the individual support elements 1 each consist of a base 3 and spring arms 4, which are attached with in one end to the base 3 and in pairs with their other ends are connected via a support ring 5.
an associated cover plate 6 is connected to the spring body of the single support element formed by the spring arms 4 (see Fig. 3 to 5 ).
a hardness setting ring 7 is provided below the spring arms 4 of each individual support element 1. This is formed with cams 8, on which the spring arms 4 can be supported during compression.
the hardness adjusting ring 7 is rotatable about a vertical axis I, which coincides with the central axis of the spring element. In a first rotational position of the Härteinstellrings 7 are four cams in the compression travel of four spring arms 4, while in a second rotational position eight cams 8 in the spring travel of the eight spring arms 4 are located. This results in the first position of the hardness setting 7 a lower hardness than in the second position.
cams 8 instead of a different number of cams 8, by which the spring arms 4 are supported, also cams of different height or different elasticity can be provided to adjust a different hardness. By rotating the Härteinstellringe 7 via the actuating arm 9, the different cams 8 can be used.
