Description

The present invention relates to a bed, in particular hospital or nursing bed, with means for assisting getting up.

The applicant offers under the name "eleganza 1" a bed equipped with means for assisting the raising of a bed-dweller. The means include a handle called a Mobi-Stick. The handle is mounted in a holder on one side of the bed. The handle allows a resident sitting on the edge of the bed when leaving the bed, so when getting up, pulls up on the handle and / or is supported on the handle. In addition, switches are provided on the handle, which the occupant while he holds on to the handle, pulls up or supported with the thumb can operate to adjust the height of the bed. The adjustment of the lying surface supports the resident and relieves the resident of getting up. This means of assisting getting up is also used in other beds of the Applicant, in which case it is sometimes referred to as Mobi-Lift.

In practice, the described handle makes a great service to the residents. It contributes to the mobilization of the residents and helps to relieve the nursing staff.

A disadvantage of the handle is that it has a fixed position on a bedside. If a resident can leave the bed with the help of the handle on both sides, a handle must be provided on each side. That's expensive. The connection of the switch integrated into the handle with a control for drives for the reclining surface adjustment requires installation effort, which is not negligible, especially because of the wiring. Although this can be eliminated by radio interfaces in the sensor and in the actuator and by batteries for powering the sensor, but then the battery state of charge must be checked regularly, which requires additional effort in practice.

This is where the present invention begins.

The present invention is based on the object to propose a bed with means for supporting the emergence of a bed-dweller, which is designed less expensive.

The object is achieved in that the sensor has at least one element for recovering energy, with which from the actuation of the sensor from the outside the necessary for the generation and transmission of the control signal energy can be generated.

Thus, the sensor is independent of a wired power supply or a power supply with a battery. There is then no consideration for a cable duct between the sensor and a power source. Nor must care be taken to ensure that batteries provide sufficient energy. On a state of charge of batteries does not need to be respected.

The interface of the sensor and the interface of the actuator of the control system of a bed according to the invention may be radio interfaces. Thus, a cable connection between the interfaces is unnecessary and it must be taken in the placement of the sensors no regard for a leadership of a cable between the interfaces. If several actuators are provided in a bed according to the invention, each actuator preferably has an interface or radio interface.

The sensor and actuator (s) may conform to the EnOcean standard or a similar standard. Sensors and actuators communicate via radio interfaces and the sensors according to the EnOcean standard have an element for generating energy. Sensors and actuators according to the EnOcean standard are increasingly used in home installations to control lights, blinds and other components of home automation. Within a bed, especially a nursing or hospital bed, sensors and actuators according to the EnOcean standard are not used.

The sensor of the control system of a bed according to the invention may comprise at least one fastening element, with which the sensor on the head part, the foot part and / or the side part can be attached, and the head part, the foot part and / or the side part of the bed, a holding structure or holding structures have, on or through which, by interaction with the at least one fastening element of the sensor can be releasably secured.

Characterized in that the sensors have one or more fasteners with which the sensor can be detachably attached to the bed, a good positioning of the sensor of the control system of a bed according to the invention is achieved.

Preferably, the sensor can be attached to the support structure or the support structures without tools and released again.

A bed with a control system, which provide a wireless signal transmission from the at least one actuator to a switching element or adjustment, wherein at the same time in the sensor, an element for obtaining the necessary for the generation of the signals to be transmitted energy is provided so that a Wired power supply for the sensor can be dispensed with allows a free positioning of the sensor with its fastening elements on the support structures on the at least one side part, the foot part and / or the head part.

The element for obtaining the energy necessary for generating the signals to be transmitted can be a piezo element, a solar cell, a Peltier element or an electrodynamic energy converter.

The actuating element may be suitable and arranged for mechanical actuation and be in operative connection with the piezoelectric element or the electrodynamic energy converter. The actuator may be, for example, a rocker or a button or be actuated via a rocker or a button.

According to the invention, it can be provided that an activation signal is sent to the receiver-side parts of the control system by a simultaneous actuation of all or some of the actuators of the sensor, with which the receiver-side parts are activated for the reception of control signals.

A bed according to the invention may comprise at least one further motor, for example for adjusting the inclination of the lying surface or part of the lying surface.

In the sensor of the control system of a bed according to the invention, the fastener may be a receptacle z. B. form with undercut edges. The receptacle can be plugged, clipped or pushed onto the holding structure of the side part, the head part or the foot part and the holding structure can be designed to be complementary to the receptacle.

It is particularly advantageous if a bed according to the invention has a handle as a means for assisting standing up and the handle and the sensor form a common component of the bed. The bed-occupant can then grasp the handle of the bed to hold onto or support it. At the same time, the bed occupant can actuate the actuating element (s), for example to control the motor for raising or lowering the lying surface. By raising or lowering the bed, the resident can be helped to get out of bed or get into the bed.

The handle may include a foot having the fastener or fasteners and a head. The head and the foot of the handle or sensor may preferably be rotatably connected to each other. Advantageously, the at least one actuating element can be provided in or on the head. It is then possible to turn the head with the at least one fastener arranged thereon or therein so that the occupant can easily reach and operate the fastener or fasteners when gripping. Preferably, the at least one actuator should be reached with the thumb of the hand, with which the occupant grasps the handle.

The handle can be ergonomically shaped. In particular, the head may have a substantially spherical shape or a barrel shape.

Such a bed can make a valuable contribution, especially in nursing and care for the elderly, to the fact that a well-groomed person regains autonomy.

A significant advantage of the bed according to the invention is that the sensors can be used free of the constraints of a wired (or battery-powered) power supply and free from the constraints of wired signal transmission. They can be freely positioned in a variety of ways, so that they can be easily accessed by the well-groomed person or caregiver and, if necessary, without limiting the safety of the well-groomed person.

Another important advantage of the bed according to the invention is that the sensors can be readily separated spatially from one another and from other parts of the control system. Thus, the sensors can readily be taken into a different space than that in which the sensors assigned to the sensors are provided.

It is possible that a sensor may be used to control several drives of a bed so that the various components of the bed are adjusted so that one can comfortably exit the bed and comfortably get into the bed.

It is possible to remove the sensor of a bed according to the invention from the bed and to attach it to a wheelchair or walker. Thus, a bed can be easily controlled from the wheelchair or walker by means of the attached sensor so that the assemblies of the bed occupy the positions for easy entry before boarding. After getting in or getting into the bed, the sensor can then be re-attached to the bed.

Another important advantage of the control system according to the invention is that a sensor of a nursing bed also Actuators outside of the bed can respond, for example, actuators, with which z. B. the ceiling light on and off or shutters or windows can be opened or closed.

The actuators of a sensor may include temperature sensors, motion detectors, brightness sensors, force, pressure or weight sensors or the like. As actuators in particular relays, digital and analog outputs, dimmers, etc. in question.

A sensor may have not only one, but also a plurality of actuators with which the same or different control signals can be generated. A sensor may be designed such that the actuating element or the actuating elements simultaneously generate the same or different or different control signals during different actuations when actuated. Various operations of a sensor could be achieved by allowing the sensor to have multiple rockers or buttons, or to move the rocker or button in a variety of ways, for example in two different directions or at different speeds.

According to the invention, the sensor may comprise a protective element with which the actuating element can be protected against unintentional actuation. The protective element may, for example, be a lid which is pivotally or slidably mounted on a housing of the sensor.

Of particular advantage is that several actuators of the control system can be programmed so that they record the same, issued by the sensor or one of the sensors control signal. On account of this control signal, the switching element of the actuator releases or releases the switching elements of the actuators for switching the at least one current path or the setting element of the actuator or the setting elements of the actuators for adjusting the at least one voltage, the at least one current or the other physical variable on the basis of taken control signal. It is thus possible to simultaneously address a plurality of actuators by means of a sensor and a control signal output by this sensor. These actuators are programmed to receive the control signal and to drive the switching element or the adjusting element on the basis of the recorded control signal. A (central) control device is not necessary in order to simultaneously switch on or off or set different assemblies or devices. However, a (central) control device may be provided, which receives the control signal and controls a plurality of switching elements or adjusting elements.

The handle-sensor unit, also referred to below as a unit, of a bed according to the invention has a head 2 and a foot 1. The head 2 is rotatably attached to the foot 1.

The foot 1 has a fastening element 11, which forms a receptacle A. In the receptacle A, a support structure of the bed can be introduced for the purpose of securing the unit to a bed according to the invention. The fastening element 11 has two projecting limbs 111, which are arranged at a distance from one another at a first end of the foot 1. The two legs 111 and a connecting them 112 web limit the approximately C-shaped receptacle. The legs 111 have mutually facing end 1111, resulting in undercuts.

The holding structure of a bed according to the invention or another object, for example a medical vehicle, in particular a wheelchair, or a walking aid, in particular a forearm crutch or a rollator, which is introduced into the receptacle A, is encompassed by the legs. Since the receptacle is open at the side, also elongate retaining structures can be introduced into the receptacle, in particular a handrail or a closing strip on a head part, a foot part or a preferably lowerable or extendable side part. Has the handrail or the end bar an at least partially uniform cross-section and is at least partially uniformly shaped on the clear cross section of the fastener 11, so it is possible to move the foot 1 on the support structure to determine its position. The clear cross section of the receptacle A is preferably adapted to the outer cross section of the support structure.

In addition to the fastening element 11, the foot 1 on a turntable 12. This turntable 12 is formed by a circular cross-section edge. Within the turntable 12 and to this coaxial a Kronenradzahnung 13 is provided. Within the Kronenradzahnung 13 and coaxial with this is a pin 14th arranged. The pin 14 has a central hole through which a screw 3 is guided, the screw head 31 abuts a shoulder 141 of the bore. Apart from the paragraph 141, the hole has a hexagonal cross section, so that an external hex of the screw head can be rotatably excluded in the hole.

Within the shoulder, through which the shank of the screw 3 is guided, the hole preferably has a circular cross-section. The screw 3 protrudes from the pin 14 also.

The head 2 of the unit has a housing with two symmetrical housing shells 21, 22. The housing shells 21,22 are connected by gluing, but can also be connected to each other in a suitable manner, including possibly design changes to the housing shells 21, 22 may be necessary. The housing shells 21, 22 form a base which serves to connect the head 2 to the foot. The base has a ring 25 with a circumferential shoulder, which engages in the turntable 12 and sits on the turntable 12 with the interposition of an O-ring 4. On the ring a Kronenzahnung 26 is provided, which is coaxial with the ring 25 and engages in the Kronenzahnung 13 of the foot. The crown teeth 13, 26 are serrated in the same way.

The pin 14 engages in the ring 25 and forms a pivot bearing for the pin 14th

The assembled housing shells 21, 22 form a barrel-shaped handle, which can be enclosed by a hand to hold on to the unit, support or pull up.

The housing further has a housing insert 23. This is inserted into an opening which is released from the assembled housing shells 21, 22. The housing insert 23 is formed in the manner of a pan and receives a sensor 5 of the unit. The housing insert 23 and the sensor 5 arranged therein are covered to the outside by operating elements 6, namely two rocker switches 61, 62 and a pushbutton 63.

The rocker switches 61, 62 are pivotally mounted on pins and / or axes of the sensor and are based on first pin 621 on restoring and energy generating elements 51 of the sensor 5 from. From a rest position predetermined by the restoring and energy generating elements 51, the rocker switches 61, 62 can be deflected by an actuation. The return and power generating elements 51 of the sensor are thereby also deflected. As a result, the energy required for the generation and transmission of a control signal is generated in the sensor 5. If then the operation, press the restoring and power generating elements 51, the rocker switches 61, 62 in its rest position. Second pins 622 of the operating rockers 61, 62 are applied to actuators 52 of the sensor. By a deflection of the rocker switches 61, 62 move the second pin 622, the actuators 52, which leads to generating and emitting the control signal that can be received by an actuator of the control system of the bed, then leads to switching a switching element, if a receiver-side part a control system of a bed according to the invention is activated. If the receiver-side part of the control system, which includes the actuators, is not activated, no switching elements are switched.

The sensor 5 has four actuators 52, each of which two actuators 52 can be actuated by each of the two shift paddles 61, 62.

The button 63 has a knob 631 which projects into a recess between the rocker switches 61, 62 to the outside. The button 63 has first pins 631 which are supported on the return and power generating elements 51 of the sensor. In addition, the button 63 has four second pin 632, each of which abuts one each on an actuating element 53 of the sensor. The button 53 is mounted linearly displaceable. When the button 53 is pressed, all four second pins press on the actuators 52 of the sensor 5, resulting in the generation and transmission of an activation signal. By receiving this activation signal, the receiver-side part of the control system, which also includes the actuators of the control system, can be activated.

The simultaneous pressing of all four actuators 52 upon actuation of the button 53 thus takes place an activation of the receiver-side control part. Only in an activated state of the receiver-side control part of the receiver-side control part is able to process the 5 sent from the sensor 5 due to the actuation of a single actuator 52 by means of the shift paddles 61, 62 control signal and switch according to the control signal switching elements. If the receiver-side control part is not activated, the control signals caused by the actuation of a single actuating element 52 remain without a reaction detectable on the switching elements.

If the receiver-side part of the control system is activated, control signals can be received within a predetermined time to control the switching elements. If no actuation occurs within this predetermined time, the receiver-side part of the control system falls back into the non-activated state.

The activation of the receiver-side part of the control system by the simultaneous actuation of all or many actuators of the sensor may also be possible with a differently configured sensor of a bed according to the invention and is not only possible in the handle-sensor unit shown in the figures.

The head 2 is secured to the foot 1 by means of a nut 7. The nut 7 is screwed onto the screw 3, which projects into the head 2. Between the nut 7 and the ring 25 of the head 2, a spring 8 is inserted, which is supported on the one hand on the nut 7 and on the other hand on the ring 25. The head 2 can be pulled away from the foot 1 against the pressure of the spring 8 in the direction of the screw 3. The crown teeth 13, 26 of foot 1 and head 2 are thus released from each other and the head 2 can be rotated freely relative to the foot 1. When the head 2 is released in the desired position, the spring 8 pulls the head 2 towards the foot 1. The crown teeth 13, 26 engage and the head 2 is fixed to the foot 1.
