Definitions

the present invention relates to a parking brake for furniture with rollers, especially beds, with which in a first state of the parking brake the furniture against rolling are detectable and in a second state of the parking brake rollers are rotatable.
a bed with such a parking brake is from the European patent application, which is under the publication number EP 1 645 257 A1 was published known.
the parking brake disclosed in this patent application has at least one one-part or multi-part locking means which is suitable and arranged for fixing the bed.
the parking brake has at least one single- or multi-part actuating means with which the parking brake can be transferred from the first state to the second state and vice versa.
the mechanism with which the retention of the parking brake in the assumed state is achieved after a discharge of the actuating means is very complex. It consists of a large number of individual parts that interact with each other. This is where the present invention begins.
the present invention has for its object to improve a parking brake of the type mentioned so that the whereabouts of the parking brake is secured in the occupied state after an operation until the next operation with simple, commercially available components.
the locking means comprises a lockable spring, in particular gas spring which is blocked in the first state of the parking brake and which is blocked in the second state of the parking brake and which is suitable and adapted when changing the parking brake from the first Condition to be solved in the second state.
Blockable springs in the context of the invention are those springs whose length can be blocked in at least two different states. By releasing the blocking, the length of a lockable spring can be changed.
the principle of a lockable spring is known, for example, from ballpoint pens, in which by arrangements with lockable springs a ballpoint pen refill can be pushed out of the ballpoint pen housing by repeated pressing on a release button, which protrudes from a ballpoint pen housing at the front or can be pulled into the ballpoint pen housing.
Lockable springs are also known as lockable gas springs.
Blockable gas springs are available as commercially available components on the market and for example from the document DE 42 36 150 A1 known. Stabilus GmbH offers such blockable gas springs, for example, under the name "Bloc-O-Lift".
the length of the gas spring as can be used in a parking brake according to the invention, is different in the first state and in the second state of the parking brake. By blocking the gas spring in the two different states of the parking brake and the simultaneous different length of the gas spring in the two states, a blocking of the rotation of the rollers can be achieved.
the gas spring may be suitable and arranged by an actuation, i. H. a force to be released in the same direction and be brought to a different length.
the gas spring may comprise a cylinder and a piston, wherein the piston is slidably disposed in the cylinder.
the gas spring is preferably designed so that the gas spring can be released by a force in the direction of the piston rod to be transferred to another state or in another position.
the actuating means may be coupled to the piston rod or to the cylinder for the purpose of releasing the gas spring and transferring the gas spring to another state.
the locking means may further comprise at least one pressure element which is suitable and adapted to block the rollers in the first state of the parking brake and to release the roller in the second state of the parking brake.
the pressure element can be suitable and arranged to be displaced between a first position in the first state of the parking brake and a second position in the second state of the parking brake.
the locking element may further comprise a coupling element, via which the piston rod or the cylinder of the gas spring is coupled to the pressure element.
the coupling element is pivotally mounted and adapted and adapted to be pivoted between a first position in the first state of the parking brake and a second position in the second state of the parking brake.
the pivot position is preferably determined by the length of the gas spring.
the cylinder or the piston rod is pivotally connected to a coupling element.
the coupling element of a parking brake according to the invention may have a guide contour for guiding the pressure element, on which the pressure element preferably bears against the pre-pressure of a spring element.
the spring element can thus be suitable and arranged for pressing the pressure element on the guide contour of the coupling element.
the actuating means of a parking brake according to the invention may be coupled via the coupling element with the pressure element to transmit actuating forces from the actuating means to the pressure element.
the actuating means is preferably hingedly connected to the coupling element.
the actuating means of a parking brake may comprise an actuating lever or an actuating pedal and a transmission element for transmitting an actuating force from the actuating lever or actuating pedal to the coupling element.
the coupling element may be designed in several parts and comprise a first coupling part, a connecting part and a second coupling part, which are preferably rigidly connected to each other.
the actuating means may be hingedly connected to the first coupling part of the coupling element.
the gas spring is preferably connected to the second coupling part of the coupling element.
the guide contour may be provided on the second coupling part of the coupling element.
a bed according to the invention in particular a nursing bed, can have footrests resting on castors and at least one parking brake of the aforementioned type.
Each two rollers can each be assigned to a parking brake.
Such a parking brake may then have, in addition to the pressure element, a further pressure element, wherein each pressure element is associated with a respective role.
Each parking brake may also have to the coupling element another coupling element, and the further coupling element may be associated with the further pressure element.
the two coupling elements of each parking brake can be coupled to each other via a respective power transmission member.
the parking brake may comprise, in addition to the actuating means, a further actuating means, and the further actuating means may be associated with the further coupling element.
FIG. 1 illustrated footrest A of a bed according to the invention rests on rollers B1, which are mounted on arms A1 of the footrest.
the arms A1 are connected to lower ends A2 of lifting columns, the lifting cylinder A4 in the FIG. 1 are only indicated.
the lower end A2 of the lifting columns is connected to a connecting plate A3, whereby the right half and a left half of the footrest are held together.
a cross member A5 On the movable upper end of the lifting cylinder A4 rests a cross member A5, on which a bed frame or a mattress frame of the bed according to the invention can rest.
the rollers B1 are part of a roller assembly B, which also includes a roller holder B2 in addition to the roller B1, in which the roller B1 is rotatably supported.
the roller holder B2 is in turn mounted rotatably about a vertical axis on the arm A1 of the footrest of the bed.
a pin is slidably mounted, which is hereinafter referred to as pressure element 11.
This pressure element 11 can be displaced between a position in which it presses on the roller B1 and thereby blocks a rotation of the roller B1. In another position, the pressure element 11 has a distance from the roller B1, so that they can rotate freely relative to the pressure element 11.
a spring element not shown, the pressure element 11 is pressed into the position in which the roller B1 is not blocked.
the pressure element 11 is part of the locking means 1 of the parking brake C of the bed according to the invention.
the pressure element 11 also include a coupling element 12 and a gas spring 10 to the locking means 1.
the locking means 1 is thus formed in several parts.
the coupling element 12, which is also designed in several parts, is pivotally mounted on the arm A1 of the footrest A.
the coupling element 12 has a first coupling part 120, a connecting part 121 and a second coupling part 122, which are rigidly connected to each other.
the connecting part 121 also forms an axis of rotation, with which the coupling element 12 is pivotally mounted on the arm A1.
the second coupling part 122 has a guide contour 1220 on which the pressure element 11 constantly bears due to the spring pressure of the spring element, not shown. Since the guide contour in a region a greater distance from the pivot axis of the Coupling element 12 has as in another area, can be moved by pivoting the second coupling part 122, the pressure element 11 from the one position in which the roller B1 can rotate freely to another position in which the roller B1 is blocked.
roller B1 In the presentation of the FIG. 3 and the FIG. 4 is the roller B1 is not blocked, that is, the pressing member 11 is in an upper position, while in the illustration of the FIG. 5 and the FIG. 6 the roller B1 is blocked and the pressure element 11 is pressed by the guide contour 1220 against the roller B1.
the coupling element 12 is connected to the actuating means 2.
the actuating means 2 has an actuating pedal 20 which is pivotally connected to a transmission element 21 of the actuating means 2.
the transmission element 21 is pivotally connected to the coupling element 12.
the operating pedal 20 is pivotally mounted on the arm A1 of the footrest A. When the operation pedal 20 is pivoted downward, the operation force acting on the operation pedal is transmitted from the operation pedal 20 to the transmission member 21 and from the transmission member 21 to the coupling member 12. Characterized the coupling element is pivoted to its first position or its second position and at the same time causes an actuation of the gas spring 10, which changes its length.
the lockable gas spring 10 has a cylinder 101 which is pivotally mounted on a cantilever A11 of the Outrigger A1 is attached.
the gas spring also has a piston rod 102 which is connected to a piston in the cylinder 101. The end of the piston rod 102 is pivotally connected to the second coupling part 122 of the coupling element 12.
the lockable gas spring 10 is actuated by an axial pressure on the piston rod.
the piston rod is displaced.
the piston rod is thereby brought in each case in a blocked position.
the piston rod can be released from this blocked position and transferred to the other blocked position.
the distance between the articulation point of the piston rod 102 and the pivot point of the cylinder 101 changes.
