The multi-position support apparatus 10 may use at least one engine to change its angular position. For decorative or space-saving purposes, the multi-position support apparatus 10 may be designed with all or most of the engines controlling its angular position concentrated beneath the seat 14.
In one embodiment, when used for cleansing, the multi-position support apparatus 10 both begins and ends in a standing position. Optionally, the angles of the multi-position support apparatus 10 are programmed so that the user returns to the standing position with maximum stability; slightly reclined. Because of its slightly reclined angle, the multi-position support apparatus 10, when in a standing position, does not throw the user off-balance. It is to be noted that the term “reclining” may be interpreted as “backward inclining.”
During bathing/washing actions (i.e. during the shower itself) with the bathing system, the probability of an accident is very low. Receiving the user from a standing position, and, when the shower is completed, returning the user to a standing position, minimizes the probability of bathing/showering-related accidents occurring. The disclosed embodiments are also useful for people who cannot stand. In those cases, the device receives the user from a sitting position, and, when the shower is completed, returns the user to a sitting position. While in the reclining position, the user is securely supported by the multi-position support apparatus 10 throughout the bathing process. Moreover, in the reclining position of the multi-position support apparatus 10, the user remains in a relaxed position throughout the bathing process.
Referring to
The angle of back support 11, seat 14, and leg support 16 may change during operation in order to achieve maximum stability and put minimal pressure on the user's legs. In one embodiment, a user enters the apparatus in a standing position, leans backwards, and upon achieving a reclined angle of, for example 20 to 60 degrees, the apparatus begins to move the user into a sitting position. When the apparatus moves from sitting to standing the user is first brought to a reclined position of between 20 and 60 degrees, and only then is brought to a full standing position.
In one embodiment, one or more sensors are placed in the foot support 17, or on the foot support 17, or in other possible locations. The sensors may be used for preventing a situation in which the multi-position support apparatus 10 descends on the foot of an operator who is not the user, such as a nurse, or crush objects in its way. The one or more sensors detect objects and prevent foot support 17 from crushing them. Examples for optional sensors are, but are not limited to, infra-red sensor, electric footboard that sends a signal when it is stepped upon, micro switch, camera, or any other sensor known in the art.
In one embodiment, one or more sensors are placed in or on back support 11. The one or more sensors prevent a situation in which back support 11 crushes an operator who is not the user, such as a nurse, or detect objects and prevent back support 11 from crushing them. Examples for optional sensors are, but are not limited to, infra-red sensor, electric footboard that sends a signal when it is stepped upon, micro switch, camera, or any other sensor known in the art.
In order to achieve a reclining position, it is possible to create an indentation in the pivot area so that the pivot will fall into the indentation when the multi-position support apparatus is stretched, as required for a reclining position.
Optionally, the armrests of the multi-position support apparatus may move up, down, and to the sides, to enhance the user's comfort. Optionally, the armrest may be detached from the multi-position support apparatus. In this case, when the multi-position support apparatus moves, the armrests do not move along with it, to allow the user to comfortably reach for an object or shelf during changes in position.
Optionally, the parallelogram-based structure device may be locked in a certain angular position. Alternatively, it is possible to create a friction-based mechanism that maintains the device in the angular position it is brought to.
Referring to the embodiments illustrated in
A foot support engine 110 may be added to all of the embodiments of the present invention.
Referring again to
The multi-position support apparatus 10 may include more than three parts. Each part may feature a separate engine. Herein disclosed are two examples of optional parts: (a) A headrest that may move up and down and change its angle in any of the three axes. An adjustable headrest is good for users with neck problems. The movement of the headrest may be controlled in conjunction with the operation of the bathing system. For example, when washing the hair, the headrest should tilt back. (b) Changing the angle of feet support 17. Controlling the angle of the feet support may help alleviate foot pain aggravated by long periods of sitting or reclining, for example, pain caused by plantar fascitis.
Engine 214 is connected to apparatus base 220 and moves rod 222 which is connected to seat 202. Rod 224 enables the movement of back-support 200. Optionally, another engine (not shown in the figure) controls rod 224.
Referring to
In order to comfortably support the user's legs as apparatus 201 reclines, angle 240 between leg-support 204 and an imaginary line perpendicular to the floor, increases until reaching a predefined angular size. Example of the predefined angular size is between 30 and 60 degrees. Multi-position support apparatus 201 optionally features leg-support 204 with length extension 210 and wheel 212. As apparatus 201 reclines, the length of leg-support 204 is extended by length extension 210, until reaching a predefined length, at which point foot-support 206 may rise above floor level. For example, the predefined length may be achieved by using a stopper, sensor or a program.
The wheel 212 enables the foot-support 206 to move freely along the floor without experiencing unnecessary friction. Alternatively, length extension 210 may be motorized, and may move in accordance with the overall reclining action of multi-position support apparatus 201. It is to be understood that the wheel 212 may be combined with all disclosed embodiments.
Engine 214 may be connected to any part of multi-position support apparatus 201 in combination with appropriate pivots and rods to achieve the capabilities of the device illustrated in
In one embodiment, the multi-position support apparatus 10 is immersed in a bathtub or placed in a shower (not shown in the figures). In one embodiment, the multi-position support apparatus 10 features liquid conduits through which a liquid passes. The liquid may be used for bathing. Examples of liquids are water, water with soap, bath oil, etc.
Hereinafter, the term “sprinkler” refers to any device that emits liquids including, but not limited to, water spreaders that are used for rinsing and/or bathing. e.g., jets, sprinkler jets, and nozzles.
In order to bathe, the user may be wet from multiple directions. The wetting process is done, at least partially, using sprinklers.
In one embodiment, all or some of the sprinklers may be placed on a device located on the side of multi-position support apparatus 10 (not shown in the figures). The device located on the side of multi-position support apparatus 10 may be similar to a device featuring sprinklers as known in the art of wall shower. Moreover, the controller of the bathing device may control the spray on the sprinklers placed on the device located on the side of multi-position support apparatus 10 in similar way to how it is controlling the sprinklers placed on multi-position support apparatus 10 itself.
As known in the art, the sprinklers are either fixed in place, or movable/mobile/handheld.
In one embodiment, the sprinklers that wet the user's back are attached to the back-support 11. Alternately, the liquid may be sprayed through holes added to the back support 11 that are large enough to allow for the passage of various liquids. Optionally, at least one sprinkler may be located on one or both of the arm rests of the multi-position support apparatus 10, to provide the user with extra spraying directions. The at least one sprinkler installed on the armrests may be a drop sprinkler, which provides, at least one more spraying direction than the number of spraying directions provided by available fixed sprinklers.
Moreover, multi-position support apparatus 10 may feature a plurality of massage elements that apply a massaging motion to the user.
The massaging device may be installed in the seat, backrest and footrest.
The massaging elements create a motion that improves cleansing by even distribution of liquids, as well as getting soap to body parts that the user cannot reach, or finds difficult to reach. In fact, the massaging fingers make it possible to soap all of the user's back without the user having to move.
Moreover, the massaging elements increase circulation, which has a positive influence on the cardiovascular system. In addition, the massaging elements aid in the removal of dead skin cells, which when left unchecked may potentially cause the development of sebaceous cysts.
When the user leans on the multiple massage elements there is a distance between the user and the spray which improved the spread of water over the body. Additionally, this design reduces the chances of the sprayer clogging, and allows improved flow of water for bathing the user.
In one embodiment, the multi-position support apparatus 10 features different lengths and therefore caters to users of various heights. Therefore, the length of multi-position support apparatus 10 should be adjusted to the height of the user. Adjustment of multi-position support apparatus 10 to the user's height may be accomplished by controlling the lengths of leg-support 16 and back-support 11.
In one embodiment, a leg-support length adjustment 21, used for adjusting the length of the leg-support for the user's height, features a telescopic device. The telescopic device may be operated either manually or by engines, as known in the art.
When multi-position support apparatus 10 shifts from the position of sitting to reclining, the user's body may slide down. This motion may cause uncomfortable friction to an unclothed body. To prevent the friction, it is possible to enable multi-position support apparatus 10 to move according to the motion of a user. For example, enabling the back of the bathing system to move according to the motion of a user's back. Referring to
According to another option, the floating is achieved by using the following optional embodiments: (a) Two or more tracks. Hereinafter, the term “track” refers to any device that enables movement along a specific direction. (b) A spring holding the floating part in place for ensuring that the floating part does not move independently. To prevent quick movement by the spring it is possible, for example, to integrate the spring with a piston. (c) Using a telescopic device which absorbs shocks. Examples are telescopic devices that may be appropriate are telescopic devices such as those used in motorcycles or automobile luggage compartments (trunks). The functionality of the telescope device is to ensure that the support is not moving by itself and/or not moving independently when the user momentarily gets up, for example to soap his feet.
The use of a telescopic device is just an example and floating parts may be implemented with any other device known in the art, such as, but not limited to, a wheelchair. As long as no command is given to change the angular position of multi-position support apparatus 10 and/or as long as the engine is idle, the floating part's position on the slide is fixed. This may be achieved by using a pin, step motor, electro-magnet, etc. In this case, the telescopic device is not needed, as the floating part is not moving independently. The floating device moves along at least one track. Examples of optional track configurations include a track down the middle, two tracks down the sides of the back-support, or any other equivalent implementation.
Optionally, instead of using a floating device, the movement may be achieved by using an engine. The control commands to the engine may be derived from measuring in advanced the distance the user's back should move as function of the angular position of the chair/apparatus.
Optionally, the floating back-device moves together with the head support.
Optionally, the back-support may be divided into more than one part. According to another option, the head-support is separated from the back-support, and thus becomes a multi-position support apparatus that is adjustable to different heights of users.
The starting positions of the floating parts may be determined according to the specific user's height. In that case, the multi-position support apparatus adjusts to different heights of users by moving the floating parts' positions according to the user's height. The taller a person is, the further apart the floating parts' starting position is in the apparatus' standing position. The following are examples of floating integrated with the multi-position support apparatus.
Referring to
The floating-parts examples may be implemented on any of the users' body supporting parts, including the backseat and leg supports. Because relative movement is needed, it is sufficient that only the back-support part and/or the leg-support part be floating. In this case, it is not necessary for the seat to move, because the back-support and/or leg-support are moving.
Every shower or bathtub has at least one water drain for collecting and draining liquids into a sewage system and/or into the appropriate disposal system. In one embodiment, the multi-position support apparatus 10 positioned so that the water drain is located beneath foot-support 17. Thus, when the multi-position support apparatus 10 is in the standing position, the water drain is neither exposed nor endangering the user. In another embodiment, the water drain features an electric pump that begins low-pressure draining of the liquids into the appropriate disposal system when the water level rises above a certain height. The purpose of the electric water pump is to prevent water from pooling in the shower.
In one embodiment, a feces-collecting device, referred to herein as “integrated toilet”, may be integrated the into multi-position support apparatus 10. The integrated toilet features significant hygienic advantages. Integrated toilets may include for example a toilet, toilet bowl, and lavatory seat. In one embodiment, the outlet of the integrated toilet is directly connected to either, an appropriate disposal system or existing toilet basin. The integrated toilet may come with a bidet and/or sitz-bath, as known in the art. In the case wherein the multi-position support apparatus 10 and the integrated toilet are installed in the shower, the toilet may be cleaned using either an existing shower spray hose, or device specified for this purpose.
There are cases where there is a need to secure the user to the multi-position support apparatus 10. For example, when the user is an elderly person suffering from Alzheimer's disease, dementia or amnesia. In either case, the user might try to get up during the washing procedure, and may fall down. In order to prevent injury, the user may be secured to the device.
Securing the user to the device may be done by using any means known in the art. For example, multi-position support apparatus 10 side-handles that close-in/wrap the user and hold the user in place, and/or support straps attached to the sides of the multi-position support apparatus 10.
Entering the multi-position support apparatus 10 comfortably is achieved using two handles, armrests, or hand supports, featuring different lengths. On one side, there is a short handle for allowing easy entry into the device; on the other side, a long handle both supports the user and prevents the user from falling from the apparatus.
Moreover, the user may be secured at the knees while standing, to increase safety and stability.
In one embodiment, it is possible to control the bathing system's operation by one or more means of the following options: (a) Operating the bathing system using a control button that enables choosing the desired program. (b) Operating the bathing system using a controller that identifies voice commands. (c) Automatic operation of the bathing system by means of user-identification. (d) Identifying the user may be achieved by any method known in the art. For example: by means of voice or visual aids, RFID, smart card, key, user's weight, control panel, etc.
After the bathing system identifies the user, a personalized program may be executed. The personalized program may include parameters such as: duration of the shower, water temperature, soap types, shampoo types, number of shampoos, etc.
In one embodiment, the bathing system is operated by one or more controller-operated engines. Control of the engines, sprinkler heads, and other devices, such as the drying device, may be operated by either the same controller or multiple controllers. The different controllers may be synchronized between themselves in order to improve the security and comfort of the bathing system user. Optionally, the controller of the bathing system may be a preprogrammed controller.
The following examples illustrate different programs that may be used to operate the bathing system.
An angular position program operates the change in angular position of multi-position support apparatus 10. For example, changing from a standing position to sitting position, and from sitting to reclining backwards. Another example is changing from backwards reclining to sitting and standing.
A bathing program, which may be synchronized with the aforementioned angular position program is operating some or all necessary bathing devices, such as, but not limited to, water, inserting soap, rinsing, controlling temperature, and drying.
In one embodiment, the bathing system is operated manually. The manual operating program activates each step/stage according to instructions from either the user or any other human operator. In another embodiment, the bathing system is operated by an automatic program that activates all stages, sequentially.
Optionally, it is possible to control the program's sequence; it also is possible to operate a combination of the various bathing programs. Optionally, the different bathing programs and their appropriate variables are stored in a memory device. The memory device may either be a part of the bathing system or an external memory device.
In one embodiment, the bathing system is operated by one of the following, or by a combination thereof: (a) the user, (b) an operator who is not the user, (c) from any place where it is possible to control the bathing system's operations via remote control or any other remote operating means as known in the art, or, (d) automatically, using methods known in the art.
In an emergency, the bathing system may operate at least one predefined emergency response operation. For example, stopping the spraying of water over the user and bringing the user to a predefined angular position: standing, sitting, or reclining. The angular position, into which the user is brought in an emergency, may the most secure angular position for the specific user. In one embodiment, it is possible to customize the bathing system with the most secure position for each user. Entering the emergency response operation may be initialized by any kind of appropriate device, such as, but not limited to, emergency button, emergency pull-rope, voice command, and etc.
In one embodiment, prior to executing the program, the bathing system activates a voice indicator which informs the user about the program to be executed. Only after the user confirms the voice-indicated selection does the bathing system activate the program. The user may confirm execution of the program by any input means known in the art, such as pressing a confirmation button, or by voice-command.
In one embodiment, the bathing system operates a selected program, according to a pre-defined period, in the event that a user does not confirm the selection. According to another option, the bathing system cancels operation of a selected program, according to a pre-defined period, in response to a user not responding.
In one embodiment, whenever the user does not react to functions of the bathing system throughout a predefined time interval, the bathing system activates one or more of the following operations: (a) Entering an emergency state as defined and disclosed herein. (b) Confirming whether the user falls asleep or if something happens to the user. Examples of confirmations are: voice alarm, visual means, or by any other means which attract the attention either of a user or a user's supervisor. Alternatively, the bathing system may send a warning signal to a predefined supervisor, such as a nurse or a care center. The warning is transferred by means of communication known in the art. Examples of communication means are voice, visual indication, telephone communications, or computer network. All the operations that may be performed whenever the user does not react to a function of the bathing system may be referred to as emergency response operations and may be implemented by using a device referred to as a device for entering an emergency response operation.
As disclosed above, an embodiment of the bathing system may feature an interface from which a variety of operations are controlled. The controller may be operated by the following optional means: manual, keyboard, voice-activation, computer-connected, for example via RS232 or USB, remote activation such as by telephone or wireless network or by any other means known in the art. In one embodiment, all or some of the parameters that have been user-customized are backuped. Examples of parameters that have undergone user-customization: User programs, angles, heights, angular change velocity, water temperature, force of sprinklers, and soap type. Parameters customized for the user may be saved in the bathing system or in any computer, or memory element, capable of communicating with the bathing system.
In one embodiment, the bathing system features a Built in Test (BIT). The BIT system may be used for fast identification of failures. This capability enables the technician to more easily determine what action should be taken when coming to the user. This also makes it easier to provide price quotes to the user prior to responding for repairs. Optionally, the BIT results may be transferred to the technician's equipment via a phone line or wireless network, or any other known in the art communication aid.
In one embodiment, When installing the bathing system at the user's site, the technician is able to set a combination of velocities, movement angles, liquid parameters, cleaning materials-related parameters, and other parameters referred to herein as “operational customized parameters” of the bathing system such that it is possible to fit the use of the bathing system to the requirements, comfort and safety of the specific user. Optionally, the operational customized parameters are saved in a memory element for future use.
It is possible to disperse steam into the shower to create the effects of a sauna. It is possible to disperse the steam from any convenient place, as long as it is not dispersed directly over the user. In one embodiment, introducing the steam is managed by either the bathing function or by manual operation.
In one embodiment, at least one pump is used, which controls the sprinklers' water pressure and supply, so that the performance of the washing device does not depend on exterior water pressure. This is especially useful whenever the external water pressure is low. In one embodiment, when the water pressure is low, the bathing system contains a water tank for accumulating water before it is sprayed onto the user. The washing device begins washing the user only when the amount of water in the tank, combined with the estimated water pressure, is sufficient for completing the planned shower.
In one embodiment, the bathing system includes a temperature controller that immediately stops the spraying of liquid if it determines the liquid's temperature to be out of the predefined temperature range. In another embodiment, the bathing system supports the integration of a fast-heating electric device. In this case, the bathing system receives cold water and heats it to a preset temperature defined and controlled by a controller.
In order to increase safety and to avoid a situation in which the user is sprayed with water which is not the desired temperature, a bypass hose is added, with an electric faucet and at least one temperature sensor. When the at least one temperature sensor detects that the temperature of the water is not in the desired range, the water is directed to the Bypass Hose, which flows into the drain or to another place where the water will not touch the user.
When the temperature inside the water tank reaches a predefined temperature range, the washing cycle may start. Optionally, some amount of the water is fed into the bathing system by using pipe 56 and some amount of the water is fed back into the water tank by a back-feeding pipe 55. Returning some of the water back into the water tank enables operating the pump according to a constant flow. Operating the pump according to a constant flow may feature a few advantages such as a longer life cycle and less power consumption. In the embodiment illustrated in
In one embodiment, the water tank and the pump are located at the base of the bathing system near the engines such that the structure of the bathing system in its entirety is aesthetic, while also occupying as little space as possible.
In one embodiment, the water temperature controller is synchronized with the overall bathing system controller. This synchronization enables the spraying of water at various temperatures over different parts of a user's body and changing the water temperature according to the different states of the system. For example, water sprayed over a user's head when it is being washed is less hot than water used to wash a user's back.
In one embodiment, a water-temperature-controller is connected to a bypass pipe. Whenever the temperature of the water fed into the bathing system by using pipe 56 is not within a predefined interval, the water is redirected to the bypass pipe. Optionally, the bypass pipe may be connected to the drain or to the water tank.
The temperature of the water and the amount and type of cleansing agent used by the bathing system may be controlled by one or more bathing system controllers. Moreover, the temperature of the water and the amount and type of cleansing agent used by the bathing system may be operated automatically, semi-automatically, or manually.
In one embodiment, a cleaning process of selected parts of the bathing system occurs following predefined operations of the bathing system. The cleaning process, for example, may feature at least one of the following: disinfecting, sanitation, sensing and drying the entire bathing system or selected part thereof. The user may activate the cleaning process by means of the bathing system's sprinklers and dryer. In one embodiment, a drying system specific for cleaning is installed. The cleaning process may be controlled by one or more bathing system controllers. Moreover, the cleaning process may be automatically, semi-automatically or manually operated. In one embodiment, the dryers are able to dry the system to such an extent that prevents the appearance of fungus and mildew.
In one embodiment, at least one of the parts used in the multi-position support apparatus 10 is an ergonomic part. Ergonomic design enhances a user's safety and comfort while also increasing product usability.
The use of at least one controllable engine for setting the angular position of multi-position support apparatus 10 makes multi-position support apparatus 10 easy to learn, easy to use, aesthetically pleasing, and marketable. Moreover, multi-position support apparatus 10 increases the safety of the user and the efficiency of the treatment supplied to the user.
Moreover, the bathing system is useful for paralyzed people in a wheelchair who need to start the action of multi-position support apparatus 10 from a sitting position in order to move easily onto multi-position support apparatus 10. For this purpose, it is possible to start the bathing system from a sitting position.
In one embodiment, it is possible to adjust the multi-position support apparatus 10 to support users in need of extra space. Non limiting examples of adjustments of the multi-position support apparatus to support users in need of extra space are making a wider multi-position support apparatus or by expanding the distance between the armrests mechanically.
Angular change that is to fast may cause dizziness in elderly people. This phenomenon is known in the art as orthostatic hypotension. Optionally, the speed at which multi-position support apparatus 10 changes its angular position may be controlled and adjusted for the comfort and health condition of a user. Optionally, when the angular position changes, it is possible to stop the apparatus by using the control panel or any other controlling device
It will be appreciated that the above described methods may be varied in many ways, including changing the order of method steps, and/or performing multiple steps concurrently. For example, using a voice indication to notify the user about an upcoming bathing system program (cycle). Many elderly people suffer from memory deficiencies, eyesight deterioration and other problems that might cause them to be afraid to use the bathing system. Voice indication before every state change or before the bathing program begins may calm down the user and improve the user's experience with the bathing system.
Some users are connected to infusions, are post-operative patients, or have external wounds. These people have body parts that should be covered to avoid contact with water. The bathing system may enable the covering of specific body parts to make the bathing process easier.
In one embodiment, the multi-position support apparatus enables a personal cover that may be cleaned or changed with ease, to be attached to or laid over the apparatus.
A main benefit of the personal cover is the ability to operate the apparatus in a non-home environment with multiple users, in order to assure that a user is not contaminated by a previous user.
In one embodiment, data is collected on the use of the bathing system.
For a variety of purposes, statistical information should be collected about bathing times. In this embodiment, the bathing system is connected to software that tracks bathing times, the programs that have already been operated, and irregular occurrences such as entering a state of emergency. Such software is useful for senior citizens' and retirement homes, and other institutions that take care of elderly and disabled people, for collecting statistical data about the elderly.
Taking a bath is not always an easy action to perform. While taking a bath, changes in heart rate may occur. These changes might be dangerous for elderly people. Optionally, a heart monitoring device or electrocardiograph (ECG) device may be integrated into the bathing system. When the device detects unusual activity, the operation may be stopped. In a case of a drastic change in the heart rate, the bathing system may activate an emergency mode.

As is commonly known, bathing in a Jacuzzi offers many advantages. In order to achieve the Jacuzzi effect, the user and sprinklers must be immersed in water.
In one embodiment, a multi-position support Jacuzzi apparatus 300 is capable of holding water like a bathtub. In this embodiment, multi-position support Jacuzzi apparatus 300 is built as a bathtub having joints, which may bring the user from a standing to a lying position. When the user is in a lying position, the apparatus sidewalls retain a water level needed for immersing at least the back of the user and some of the sprinklers in water, and thus the Jacuzzi effect is made possible. The height of the sidewalls may be the same as the desired water level or higher than the water level in order to prevent water from spilling over unnecessarily. Optionally, the water level in multi-position support Jacuzzi apparatus 300 is measured by an appropriate sensor and controlled by a controller. The water flow controller may be operated in a closed or open loop manner.
Optionally, multi-position support Jacuzzi apparatus 300 features a water pump and an air pump, thereby enabling the Jacuzzi sprinkles to provide both water flow and airflow as needed.
Because multi-position support Jacuzzi apparatus 300 may hold enough water to immerse the user's back in water, it is similar to a bath system enabling operation of the sprinkles inside the water.
It is to be noted that water may spill out of multi-position support Jacuzzi apparatus 300 without interfering with the regular operation of multi-position support Jacuzzi apparatus 300, as new water is constantly flown in through sprinklers or other designated water openings.
In one embodiment, at least one of the parts from the group featuring back-support, seat, leg-support, foot-support, and bath joints, is capable of holding water, either individually or in combination with other parts.
In this embodiment, when multi-position support Jacuzzi apparatus 300 is in its fully reclined position, back-support 302, seat 304, and leg-support 306 forms a tub. In alternative embodiments (not shown in the figures), only some parts of multi-position support Jacuzzi apparatus 300 are capable of holding water and performing a Jacuzzi effect. For example, in one embodiment, the seat, back-support and their connecting joint form a water-holding vessel, while the leg support holds water separately. In another embodiment, the seat and/or leg support each hold water separately, while the back-support does not hold water. Other formations are also possible.
In other embodiments, the multi-position support Jacuzzi apparatus 300 may provide a Jacuzzi effect in other positions, such as a sitting or partially reclining position, and does not have to reach a fully horizontal position of 180 degrees. This may be achieved by multi-position support Jacuzzi apparatus 300 having a smart inner and/or outer construction.
In the case where the multi-position support Jacuzzi apparatus 300 is not totally horizontal in the fully reclined position, back-support 302 may be opened from the top and still retain water.
Joints (310,312) of multi-position support Jacuzzi apparatus 300 may comprise rubber parts which are capable of changing shape or angle while retaining water in the apparatus tub. For example, joints (310,312) may be shaped as a rubber accordion, capable of bending. Alternatively, joints (310,312) are able to retain water in the apparatus tub only when multi-position support Jacuzzi apparatus 300 is in its fully reclined position.
As illustrated in
Referring again to
A foot Jacuzzi may be an integral part of multi-position support Jacuzzi apparatus 300, or may be attached to multi-position support Jacuzzi apparatus 300. In one embodiment, the foot Jacuzzi operates when the feet are parallel to the floor, optionally, when the user is in a sitting position. Optionally, in order for the apparatus to both include a foot Jacuzzi and have the foot-support at floor level when multi-position support Jacuzzi apparatus 300 is in a standing position, a recess may be made in the floor beneath the foot-support. The recess may contain the Jacuzzi mechanism when multi-position support Jacuzzi apparatus 300 is in a standing position. The recess includes a water drain and may feature an electric pump that pushes the water into a disposal system in order to prevent the water from flooding the bathing area.
Multi-position support Jacuzzi apparatus 300 has many advantages. For example, it enables elderly or disabled people to enjoy a Jacuzzi without facing the danger of slipping and the dangers caused by awkwardly entering a regular shower. Additionally, the fact that the user's head may be safely kept out of the water during bathing enables elderly people and people suffering from drowsiness to enjoy a Jacuzzi.
In one embodiment, spring elements surface is used for seat and/or back rest and/or legs support and/or head support and/or any other surface bearing some of the user's body weight. This embodiment may be integrated with all prior art devices, and especially with the disclosed embodiments of the multi-position support apparatus, such as the multi-position support apparatus 10 illustrated in
The spring elements surface may be placed on any support apparatus used for bathing application. For example, bathing chair, bathing bed, and bathing slanted support surface. The spring elements surface features a plurality of elastic spring elements. In one embodiment, the elastic spring elements are leaf shaped as known in the art. The shape, size and number of elastic spring elements provide sufficient support to the body weight of the user. In another embodiment, the spring elements are spiral springs.
The spring elements surface may be made of any known in the art material as long as the required resilient characteristics are achieved. In principle, the spring elements may be disposed adjacent each other in any manner as long as it is simply guaranteed that a suitable force transference to achieve the desired spring comfort, that is to say the impression of sitting on something soft on the seat, is guaranteed.
The spring elements surface features the following parts: (a) a fenestrated support area that supports the body weight, (b) at least one spring element, and (c) connecting area to the supporting apparatus.
The support area is the area on which the user leans. In one embodiment, the support area is upholstered, as illustrated in
Fenestrated support area 408 may be produced in all sizes and shapes, such as, for example, rectangular, square, oval, round, and triangular.
The spring element of the spring elements surface should comfortably absorb the body weight of the user while disturbing as less as possible to the liquid spraying, as illustrated, for example, by reference 406 in
In one embodiment, the spring elements are designed like a leaf spring and feature a connecting area to the supporting apparatus.
The spring element area placed between the support area to the connecting area described below.
The connecting area to the supporting apparatus serves to attach the spring element to the support apparatus and/or to designated supporting device. Optionally, the connecting area to the supporting apparatus is detachable and/or enabling the use of appropriate fastening devices, such as screws, rivets and clip elements.
The spring element may be produced in various ways. For example, using the leaf spring disclosed in US patent application 20040111799 to Ernst Bock. Bock discloses an elastic spring element designed like a leaf spring and comprising a connecting area, a support area as well as a spring element area coupling the connecting area with the support area. The connecting area serves the fastening of the leaf spring to the respective lying surface. In order to attach the element to respective lying surface, the connecting area may contain, for example, a receiving feature in the form of a through-hole, through which a fastening device, such as a screw, may be guided and screwed in. Alternatively, the connecting area may comprise fast snap-fit elements, which are inserted into corresponding recesses or placed onto corresponding projections.
In one embodiment, arranging a plurality of leaf springs creates an extensive support area. The leaf spring is attached to the surface at only one spot in rounded connection; the rounded connection gives the spring ability to resiliently bend over in all directions of the surface, the bending angle covers 360 degrees of the surface. For example, the leaf spring can bend horizontally and/or vertically over the surface. Moreover, the leaf spring can bend to the depth of the surface. Each leaf spring element is individually adjustable to the amount and direction of the force applied by the user's body weight. For example, when placing a number of leaf spring elements in back rest device, the leaf springs adjust to support the back of the user.
When placing number of leaf spring element next to each other, a small gap is left in order to prevent the user's skin from being pinched. In one embodiment, several elastic spring elements of equal and/or differing stiffness levels may be combined with each other as needed based on the modular concept and be connected with the lying surface. This creates the already addressed individualization of the lying comfort level, wherein, especially with regard to the modular concept, a combination of various different elements with each other is possible.
In one embodiment, the spring devices exhibit different levels of spring stiffness so that not only spring elements with the different spring stiffness levels may be combined individually with each other, but also that it offers the possibility of adjusting a spring element in terms of its spring stiffness. Different spring stiffnesses enable better support for sensitive body parts like the head.
The extensive support of the spring elements surface provides maximum comfort, and there is no need to add a mattress on top of the spring element surface. The comfort of the surface enables the user to lean on the spring element surface without clothing, with bare skin, without feeling uncomfortable. Using the spring elements surface without any cover or mattress provides better hygienic use in public places, because cleaning the surface is easier and faster after every use. Moreover, covering the spring elements surface with a sheet or another cover may also provide better hygienic use, because the cover may easily be replaced between different users.
In one embodiment, the spring elements surface is used for bathing applications. A sprinkler may be attached to the connecting area of the supporting apparatus. In that case, the spring element should be designed to have such a shape that enables maximum spreading of the liquid from the sprinkler.
Alternatively, the sprinklers may be placed behind the spring elements surface, or even behind the support apparatus. Referring again to
The leaf spring may feature a minimal supporting area and the shape of the spring elements of the leaf spring may ensure good spreading of the liquid over the user's body. Moreover, the leaf spring surface distributes the weight of the user's body because the spring elements are able to bend in every direction, so the surface is more comfortable and may be used without clothing.
In addition to the above disclosure, the spring elements surface may provide the following benefits: Using the spring elements surface without a mattress or cover enables better hygienic maintenance, because there is no need to clean a mattress in case of unintentional leakage of body liquids, which is common when using the device in a hospital or nursing home. The leaf spring covers a small percentage of the user's body surface, thus enabling optimal spread of the bathing liquid on the user's body and better bathing. The spring elements surface may be made of springs having different size and/or stiffness which provide the best comfort level according to the surface size. The spring suspension surface does not lose its outer shape under compressive load as the pressure is absorbed by the fashioning of the individual spring members.
In one embodiment, a bathing system featuring at least one spring elements surface, receives and releases a user in a completely upright standing position. Moreover, the multi-position support apparatus may feature a seat pivotally attached to a back support and a leg support, wherein the back support, the seat and the leg support are adjustable relative to one another, such that the multi-position support apparatus is adjustable between reclining, sitting and standing positions, wherein in the standing position the back support, the seat support and the leg support are all generally vertical. Moreover, a multi-position support apparatus may feature a calf support and a foot support. The seat may include a pair of buttock supports. Liquids conduits may be included for passing a cleansing liquid directed toward the groin area of a user sitting in the multi-position support apparatus. Moreover, a head-bathing device may be attached to an upper portion of the back support, with liquid conduits for passing a cleansing liquid directed towards the scalp of a user sitting in the multi-position support apparatus. The seat may be pivotally attached to a base. Moreover, a drying device may be mounted on the back support, the seat, the leg support and/or the head-bathing device, to direct drying air at a user sitting in the multi-position support apparatus.
