Abstract

A patient-supporting device is disclosed. The patient-supporting device includes a fastening assembly that fastens the patient-supporting device to a structural member, a support member configured to receive a body part of a patient, and a height adjustment assembly that adjusts a distance between the fastening assembly and the support member. The height adjustment assembly includes a locking assembly and an elongated member. The support member is attached to a first end portion of the elongated member. The locking assembly is stationary relative to the fastening assembly. The elongated member is guided in an aperture of the locking assembly in a longitudinal direction of the elongated member. A plurality of first snap-in recesses is disposed on a first side portion of the elongated member. The locking assembly includes a first locking member.

First claim

What is claimed is:

1 . A patient-supporting device, comprising:
a fastening assembly that fastens the patient-supporting device to a structural member; a support member configured to receive a body part of a patient; and a height adjustment assembly that adjusts a distance between the fastening assembly and the support member; wherein the height adjustment assembly includes a locking assembly and an elongated member; wherein the support member is attached to a first end portion of the elongated member; wherein the locking assembly is stationary relative to the fastening assembly; wherein the elongated member is guided in an aperture of the locking assembly in a longitudinal direction of the elongated member; wherein a plurality of first snap-in recesses is disposed on a first side portion of the elongated member; wherein the locking assembly includes a first locking member; and wherein the first locking member, in a locked position, selectively engages in one of the plurality of first snap-in recesses and substantially prevents a movement of the elongated member in a first direction.

2 . The patient-supporting device of claim 1 , wherein the height adjustment assembly adjusts the distance between the fastening assembly and the support member by at least 5 cm.

3 . The patient-supporting device of claim 1 , wherein the height adjustment assembly adjusts the distance between the fastening assembly and the support member within a predetermined setting range, with the distance being set stepwise within the setting range.

4 . The patient-supporting device of claim 1 , wherein the plurality of first snap-in recesses, when viewed in the first direction, are beveled so that the elongated member is moved in a second direction that is opposite the first direction when the first locking member is disposed in the locked position.

5 . The patient-supporting device of claim 1 , wherein:
the first locking member is movable between the locked position and an unlocked position; and in the unlocked position, the first locking member allows a movement of the elongated member in the first direction.

6 . The patient-supporting device of claim 5 , wherein:
the first locking member is preloaded in the locked position by a resilient member; and a first lever moves the first locking member against a resetting force of the resilient member, from the locked position into the unlocked position.

7 . The patient-supporting device of claim 1 , wherein:
a plurality of second snap-in recesses is disposed on a second side portion of the elongated member; the locking assembly includes a second locking member; and in a locked position, the second locking member selectively engages in one of the plurality of second snap-in recesses and substantially prevents a movement of the elongated member in the first direction.

8 . The patient-supporting device of claim 7 , wherein the plurality of second snap-in recesses, when viewed in the first direction, are beveled so that the elongated member is movable in the second direction when the second locking member is disposed in the locked position.

9 . The patient-supporting device of claim 7 , wherein:
the second locking member is movable between the locked position and an unlocked position; and in the unlocked position, the second locking member moves the elongated member in the first direction.

10 . The patient-supporting device of claim 9 , wherein:
the second locking member is preloaded in the locked position by a resilient member; and a second lever moves the second locking member against a resetting force of the resilient member, from the locked position into the unlocked position.

11 . The patient-supporting device of claim 10 , wherein the locking assembly is configured so that, for unlocking, the first lever and the second lever are moved in opposite directions.

12 . The patient-supporting device of claim 10 , wherein an end portion of the first lever and an end portion of the second lever are disposed in a recess of the fastening assembly.

13 . The patient-supporting device of claim 5 , wherein the elongated member is movable in the first direction when the first locking member and a second locking member are disposed in the unlocked position.

14 . A patient-supporting device, comprising:
a fastening assembly that fastens the patient-supporting device to a structural member; a support member configured to receive a body part of a patient; and a height adjustment assembly that includes a locking assembly and an elongated member; wherein the support member is attached to a first end portion of the elongated member; wherein the elongated member is guided in an aperture of the locking assembly in a longitudinal direction of the elongated member; wherein a plurality of snap-in recesses is disposed on a side portion of the elongated member; wherein the locking assembly includes a locking member; wherein the locking member, in a locked position, selectively engages in one of the plurality of snap-in recesses and substantially prevents a movement of the elongated member in a first direction; wherein the locking member is preloaded in the locked position by a resilient member; and wherein a lever moves the locking member against a resetting force of the resilient member, from the locked position into the unlocked position.

15 . The patient-supporting device of claim 14 , wherein:
a groove is provided in the elongated member, a pin being connected to the fastening assembly protruding into the groove; and a resilient abutment is disposed at an end portion of the groove.

16 . The patient-supporting device of claim 14 , wherein at least one of the support member, the height adjustment assembly and the fastening assembly are formed from carbon fiber-reinforced plastic.

17 . The patient-supporting device of claim 14 , wherein the fastening assembly includes a U-shaped recess that receives the structural member and a plate that closes the U-shaped recess.

18 . A patient-supporting device, comprising:
a fastening assembly that fastens the patient-supporting device to a structural member; a support member configured to receive a body part of a patient; and a height adjustment assembly that includes a locking assembly and an elongated member; wherein the support member is attached to a first end portion of the elongated member; wherein the elongated member is guided in an aperture of the locking assembly in a longitudinal direction of the elongated member; wherein a plurality of snap-in recesses is disposed on a side portion of the elongated member; wherein the locking assembly includes a first locking member and a second locking member; wherein each of the first locking member and the second locking member, in a locked position, selectively engages in one of the plurality of snap-in recesses and substantially prevents a movement of the elongated member in a first direction; wherein each of the first locking member and the second locking member is movable between the locked position and an unlocked position; and wherein when moving from the locked position to the unlocked position, the first locking member and the second locking member move in opposite directions.

19 . The patient-supporting device of claim 18 , wherein a cross adjustment assembly moves the support member in a predetermined cross adjustment range relative to the height adjustment assembly.

20 . The patient-supporting device of claim 19 , wherein adjust
