Definitions
- the invention relates to an adjustable bed or bed.
- Such couches are well known.
- the couches are preferably divided into several sections which are pivotally connected to one another.
- the adjustment also includes at least one locking device for the moving parts in the respective swivel position.
- couches which are provided on different parts with a motorized adjustment.
- the motorized adjustment allows adjustment to any desired position while lying down. Without motor adjustment, most people are forced to approach the optimal position in several attempts.
- the motorized adjustment also contains a risk of injury. This is especially true if the bed consists of a seat part and upper body parts and leg parts that are adjustably attached to it. If both parts are adjusted against each other by an overlying person, the overlying person can be clamped between the two parts. There is a risk of injury to the feet on other loungers because the feet can be clamped under the foot section.
- the object of the invention is to eliminate the risk of injury. According to the invention, this is achieved in that a separate adjusting motor is provided for at least each pivotable part from which there is a risk of injury, and in that for each adjusting motor there is a path limitation with respect to the adjacent lying part. This ensures that adjacent parts of the bed do not come excessively close to one another and thus cause a risk of injury.
- the advantages are particularly important for couches with an upper body part and a separate leg part.
- a path limitation for the leg part and the foot part is preferably provided, so that a jamming of the feet between the foot part and the ground is prevented.
- Adjustment motors with self-locking and / or locking are preferably provided.
- Self-locking occurs e.g. by using a gearbox with a spindle or a threaded rod.
- a gearbox with a spindle or a threaded rod.
- the spindle or the threaded rod and / or the nut can be arranged such that they can rotate.
- a gearwheel can also interact with the spindle. If a gearwheel is used, at least the spindle or the threaded rod is provided with a drive motor.
- the self-locking of the spindle or threaded rod is stronger, the lower the pitch of the spindle or the pitch of the thread on the threaded rod.
- a motorized lock is preferably provided.
- the spindle or the threaded rod and / or the nut are optionally provided with a drive motor.
- the drive motors can also have a lock. Stepper motors are cheap. Stepper motors are available in the locking position in the respective step position.
- FIG. 1 to 4 show a couch with a seat part 1, a leg part 4, a foot part 5, an upper body part 2 and a head part 2.
- the various parts are articulated to one another.
- the joints are provided with conventional hinges with interlocking moving parts which are connected to one another by a hinge pin.
- flexible parts made of plastic or spring sheet metal are optionally provided as hinges.
- the seat part 1 is also firmly connected to a solid substructure.
- the solid substructure has sweeping feet 6 made of aluminum profile.
- a perforated profile is provided to reduce the weight.
- two spaced-apart profiles with an arcuate curvature are provided.
- the arc has its largest bulge in the area of contact with the seat part 1.
- the arch swings towards the ends of the bed until the profiles come into contact with the surface.
- the profiles are tapered towards the ends.
- Parts 10 and 11 are provided on parts 1, 2 and 3. These parts form stiffeners and bearing brackets for the articulated connection of electric lifting motors 9.
- Embodiment are not shown.
- the lifting motors have a spindle 12 which can be moved out of the housing by rotation and retracted again.
- the spindles 12 are articulated at the head to the opposite part 10, which forms a bearing bracket.
- At the other end of the lifting motors 8 and 9 is an articulated
- All lifting motors are electric stepper motors, which are locked in the respective step position.
- the lifting motors are provided with a swivel limitation.
- the swivel limitation takes place by means of a computer, the step position being recorded and the swivel position being determined from the respective step position.
- Swivel movement are involved.
- the swivel position that belongs to each step position is measured. By comparing that to everyone
- Data belonging to the pivot position can prevent the further extension of a lifting motor or the further retraction of a lifting motor and an excessive approach of the moving parts or an excessive spreading of the moving parts.
- the computer acts in the embodiment on the control for the lifting motors, so that the
- Lift motors can only be moved in a harmless direction than in a harmless one
- Direction can be retracted or extended.
- the lifting motors are designed in the exemplary embodiment so that they can be adjusted in any position of parts 1 to 5 against a point load at the far end of the parts. This means that even absolutely heavy people can sit or lie anywhere on the bed and the bed can still be adjusted by motor.
- a design for 200 kg is provided, in further exemplary embodiments a design for only 100 kg is provided.
- parts 1 to 5 and the adjusting mechanism are designed so that occurring loads can be withstood. That includes that
- the lifting motors 8 and 9 are arranged at a short distance from parts 1 to 5 so that the lifting motors in the side view of the bed are essentially in a line one behind the other, the line in FIG. 4 running approximately parallel to the contour of the bed support surface and wherein the line in the lying positions according to Fig. 1 to 3 of the contour of
- Bed support surface is adjusted, i.e. has essentially the same contour.
- substantially the same includes deviations of a longitudinal axis of the lifting motor up to 20 degrees from the parallel to the closest lying part or to the contact surface of the closest lying part.
- the distance between the lifting motors 8 and 9 is 15 cm in the exemplary embodiment, in others
- the design described gives the adjustment mechanism advantageous ground clearance and reduces the risk of injury. This prevents a user from getting into the adjustment mechanism with their feet.
- the adjustment mechanism is also arranged centrally under the bed, so that the adjustment mechanism is also inaccessible to the hands of the user and one
- a mattress-shaped cushion (not shown ) lies on the parts
- the cushion encloses parts 1 to 5 and their parts
- the further pivoting movement of parts 2 and 4 is blocked in the exemplary embodiment if the parts enclose a pivoting angle of less than 70 degrees between them.
- the position is shown in Figs. 1 and 2.
- a smaller or larger included angle is selected as the limit value.
- the limit value can be changed by changing the computer settings. 1 and 2, the foot part 5 is horizontal.
- the computer and the control also prevent the foot part 5 from coming into contact with the ground.
- a safety distance is provided between the end of the foot part 5 and the ground, so that a foot that has accidentally got under the foot part 5 is not injured.
- Fig. 3 shows a lying position, in which both parts 4 and 5 are horizontal.
- Fig. 4 shows a lying position in which all parts 1 to 5 are horizontal.
