DETAILED DESCRIPTION OF EMBODIMENTS

[0027] FIGS. 1A to 1C shows a walker device 10 having a lift 30 for lifting and supporting a body of a person, such a disabled person. The walker device 10 includes a structure 12 configured to allow a disabled person to be supported by two sides of the structure. The structure 12 includes a first side member 14 and a second side member 16 configured to be disposed on a surface, such as a floor or the ground, and to extend upwards. The structure 12 further includes a top member 18 coupling the first and second side members 14 and 16 to one another at a top portion thereof. The top portion 18 is configured such that at least a bottom portion 14a of the first side member 14 is disposed at distance from a bottom portion 16a of the second side member 16. This way, a person can be disposed between the first and second side members 14 and 16. It is appreciated that in order to allow a disabled person to stand or sit between the first and second side members 14 and 16, the top portion 18 is disposed at a height which allows the disabled person to stand or sit between the first and second side members 14 and 16.

[0028] According to an example, the first and second side members 14 and 16 can be extendable such that the height thereof can be adjusted in accordance with the height of disabled person, or such that the overall height of the walker device 10 meets other requirements. For example, the overall height of the walker device 10 can be determined such that the walker device 10 can be maneuvered within a residential room equipped with furniture etc.

[0029] According to an example, the distance between the first and second side members 14 and 16. For example, the between the first and second side members 14 and 16 can be coupled to the top portion 18 by hinges 22, such that the first and second side members 14 and 16 can be pivoted with respect to the top portion 18 adjusting thereby the distance between the bottom portion 14a of the first side member 14 and the bottom portion 16a of the second side member 16. This way, the side members 14 and 16 can be pulled towards one another and the structure 12 can be maneuvered in areas with limited space, for example a doorway, etc.

[0030] According to other examples, the dimensions of the top portion 18 can be adjustable for example, the bars extending between the first and second side members 14 and 16 can be telescopic, such that the distance between the latter can be adjusted as required.

[0031] According to an example, the structure 12 can further include a pivoting arm 25 coupled to the first and second side members 14 and 16 and configured to pivot and thereby displace the side members towards or away from one another. The pivoting arm 25 can be configured with number of folding joints 28, configured between a deployed state and a folded state. In the deployed state the joints 28 are horizontally disposed urging thereby the first and second side members 14 and 16 away from one another. In the folded state, on the other hand, the joints 28 are folded and disposed such that at least some of them are vertically disposed, pulling thereby the first and second side members 14 and 16 towards one another.

[0032] The pivoting arm 25 can be including a sliding member 27 configured to pull the joints 28 upwards, to the folded state, pulling thereby the first and second side members 14 and 16 towards one another. For example the pivoting arm 25 can include a joint extending from each of the first and second side members 14 and 16, and a sliding member 27 coupling the two joints 28 together and being coupled to the top portion 18, such that when the sliding member 27 slides upwardly towards the top portion 18 the side members 14 and 16 are pulled towards one another.

[0033] According to an example the sliding member 27 can be operated by an automatic drive, such as a pneumatic or electric motor, and can be controlled by a user via a designated control panel (not shown).

[0034] According to an example the first and second side members 14 and 16 are provided with wheels 20 such that the walker device 10 can be maneuvered around the house. For example the disabled person can hold the first and second side members 14 and 16 such that the structure 12 provides him with stability and balance and independently walk around the house.

[0035] The walker device 10 further includes a lift 30, coupled to the top portion 18 and having a gripping member 32 attached thereto. The gripping member 30 is disposed between the first and second side members 14 and 16 and is configured to be displaced up and down by the lift.

[0036] According to the illustrated example the lift 30 includes an extending arm 34 configured to shift between and extended position (shown in FIG. 1B) and a retracted position (shown in FIG. 1C). The gripping member 32 according to this example further includes a strap 36 coupled to the distal end 35 of the extending arm 34 and extending downwards between the first and second side members 14 and 16. This way, the strap 36 and the gripping member 32 are displaced by the extending arm 34 up and down. I.e., at the retracted position of the extending arm 34 the strap 36 and the gripping member 32 are at the bottommost position thereof, while at the extended position of the extending arm 34 the strap 36 is pulled by the distal end 35 of the extending arm 34 pulling therewith the gripping member 32 to the uppermost position thereof.

[0037] According to the present example, the gripping member 32 includes two rings 38, each extending adjacent one of the first and second side members 14 and 16. The rings 38 are configured to be disposed over an arm of a disabled person, and are disposed such that each ring is located adjacent one arm of a disabled person standing or sitting between the first and second side members 14 and 16.

[0038] The strap 36 according to this example extends down from two sides of the distal end 35 of the extending arm 34, such that each of the rings 38 is coupled to one side of the strap 36. This way, a disabled person sitting between the first and second side members 14 and 16 can insert his/her arms into the rings 38. When the extending arm 34 is shifted to the extended position thereof the two sides of the strap 36 are pulled by the distal end 35 of the extending arm 34 pulling therewith the rings 38 and the disabled person holding the rings 38. Thus, assisting the disabled person to shift from a sitting position to a standing position.

[0039] According to an example, the rings 38 can be configured to be mounted under the axilla of a disabled person, such that when the rings 38 are lifted, the disabled person is lifted therewith.

[0040] The lift 30 can further includes an anti-tangle member 40, which can be disposed on the top portion of the first and second side members 14 and 16. The anti-tangle member 40 can include two members each of one of the first and second side members 14 and 16. The anti-tangle member 40 can include two or more rollers 42 configured such that the strap 36 slides therebetween, and is straightened, ensuring thereby the smooth displacement of the strap 36 up and down.

[0041] Reference is now made to FIG. 2, in another example of the walker device 10, in which like elements are designated by like reference numerals, the lift 30 can include a rotating spool 50 operated by a motor 52, and configured to wind the strap 36 thereon. Since, according to the present example, the strap 36 is disposed on two sides of structure 12, i.e. adjacent the first and second side members 14 and 16. The rotating spool 50 includes a first spool 50a rotating in one direction and a second spool 50b rotating in an opposite direction.

[0042] The rotating spool 50 is configured to rotate in an extending state, in which the strap 36 is displaced downwardly, and in a collecting state in which the strap 36 is pulled upwardly. Thus, in the extending state each of the first and second spools 50a and 50b is rotated in a direction towards the first and second side members 14 and 16, respectively, such that the strap 36 is displaced downwardly, along the first and second side members 14 and 16.

[0043] In the collecting state, on the other hand, each of the first and second spools 50a and 50b is rotated in a direction toward the middle of the structure 12, thereby pulling the strap 36 upwardly.

[0044] It should be noted, that while the displacement of the extending arm 32 of the previous example to the extended position is limited by the length of the arm 32, the rotation of the motor 52 and the spool 50 is not limited, such that a continuous rotation of thereof can pull the gripping member 32 such that it can cause harm to the disabled person. Thus, the motor 52 can be provided with a safety sensor, configured to stop the operation thereof as the gripping member reaches a predetermined height.

[0045] The walker device according to the illustrated example include a gripping member 60 in the form of a horizontal rod 62. The horizontal rod 62 is coupled to the straps 36 at the two ends thereof, i.e. adjacent the first and second side members 14 and 16, such that the horizontal rod 62 can be pulled up and down. The horizontal rod 62 can be configured to be gripped by a disabled person, or to be disposed under the axilla of a disabled person, such that when the horizontal rod 62 is pulled up by the lift 30 the disabled person is lifted up therewith, for example from sitting position to standing position.

[0046] FIG. 3 illustrates another example of the walker device 10, in which like elements are designated by like reference numerals, and in which the lift 30 includes a rotating spool 50, as in the example of FIG. 2, and a gripping member 32 having a pair of rings 38 as in the example of FIGS. 1A to 1C.

[0047] FIG. 4 illustrates an example of the walker device 10, in which the lift 30 includes a rotating spool 50, as in the example of FIG. 2, and a gripping member 32 having a pair of rings 38 as in the example of FIGS. 1A to 1C. According to this example, however, the structure 12 includes a telescopic rod 70 coupled on one end thereof to the first side member 14 and on the other end thereof to the second side member 16. The telescopic rod 70 can be configured to retrace and extend depending on the distance between the first and second side members 14 and 16. The telescopic rod 70 can be configured with a drive configured to automatically and selectively retract or extend the telescopic rod 70 setting thereby the distance between the first and second side members 14 and 16.

[0048] It will be appreciated that according to the latter example, the sliding member does not include an automatic drive, rather the sliding member is displaced by the displacement of the telescopic rod. 70.

[0049] The telescopic rod 70 and the operation of the lift can be control via a control panel (not shown), such that a disabled person can independently stand or sit and walk around the house.

[0050] It is appreciated that while the lift is in the extended position, i.e. the gripping member is disposed upwardly, the latter can be configured to support the disabled person while walking. That is to say, the lift is configured to withstand the gravitational forces exerted by the disabled person.

[0051] Those skilled in the art to which the presently disclosed subject matter pertains will readily appreciate that numerous changes, variations, and modifications can be made without departing from the scope of the invention, mutatis mutandis.
