Description
SUPPORT APPARATUS FOR A HANDICAPPED PERSON
BACKGROUND
Handicapped persons whose legs are too weak to support their weight have little choice but to spend their days Iying down or in a sitting position. Several apparatus have therefore been developed to allow such persons to occupy a tilted or vertical position during a few hours each day, thereby improving the comfort of the person and the blood circulation.
An example of an apparatus known in the art is the U.S. patent no. 4,987,622 tSHOCKEYI, which discloses a self-operated stand up support apparatus. This apparatus comprises a support bed pivotally connected to a main support frame assembly. A power actuator assembly, including a power screw connected to the support bed and controlled by a motor, allows to pivot the bed from a horizontal to a vertical position. Also known in the art is the U.S. patent no. 5,489,258 (WOHNSEN
et al.). This patent also discloses a body support apparatus with a tiltable structure to support a user body. This structure is connected to a base frame by a pneumatic shock assen~bly to urge the support structure from a horizontal position to a vertical position.
Support apparatus currently used present several drawbacks. They are bulky and therefore are difficult to store or transport from one location to another.

The support apparatus (6) according to the present invention is for supporting aperson in a tilted or generally vertical position. As can be seen on FIG. 1, theapparatus (6) comprises an elongated and ground-engageable base (8), having a first end (10) and a second end (12). Advantageously, the base (8) may be provided with ground engageable wheels (116) supported by wheel supports (118), to facilitate transportation of the apparatus (6). To further stabilize the apparatus (6), a removable extended stabilizer (120) may also be provided.
A first arm (14) and a second arm (16) are pivotally connected to the base (8), both being pivotable in a vertical plane. The first arm (14) has a lower end (18) and an upper end (20), the lower end (18) being pivotally connected to the base (8) adjacent to its first end (10). The second arm (16) also has a lower end (22) and an upper end (24). The lower end (22) of the second arm (16) is pivotally connected to the base (8) at a location which is distal from the first end (10) thereof. In the illustrated embodiments, the distal location is about the center of the length of the base (8). The upper ends (20,24) of the first and second arms (14,16) are operatively joined by a horizontal connecting member (26) which is pivotally connected between the upperends (20, 24). The connecting member (26) thus ensures that both arms (14,16) are moved in a coordinated fashion when they are pivoted. These arms (14,16) and theconnecting member (26) provide a supporting assembly on which the body-receivingtable (28) is connected, as explained hereinafter. The pivot movement of the arms (14,16) moves the upper ends (20,24) in an arc-shaped movement with a vertical component. Thus, pivoting the arms (14,16) moves the upper ends (20,24) up and down, providing height adjustability to the table (28) connected thereto.
Advantageously, this feature allows to more easily set the person to be supported by the apparatus (6) on the table (28): For example, the height of the table (28) can be adjusted to extend flush with a bed or a sofa, and the user body can simply be rolled onto the table (28) with minimum efforts and attending personnel.
According to the present invention, the rotation of the first and second arms (14,16) is made possible by a screw (30) extending horizontally and longitudinally in the base (8) and pivotally connected thereto by means of bearings (31). A pivoting mechanism (32) links the screw (30) to at least one of the first and second arms (14, 16), to transform the rotation of the screw (30) in a pivot torque. The pivotingmechanism (32) further allows to lock in position said first and second arms (14,16).
The arms (14,16) are then moveable in any position between an upright position (FIG.1) and an inclined position (FIG.2). The screw (26) is operable either manually, by a crank (90) as show in FIG. 1, or with the help of an electrical motor (92) illustrated in FIG. 4. It should be noted that it is necessary to only directly connect one of the arms (14,16) to the screw (30), the other being then indirectly connected by means of the connecting member (26).
According to a preferred embodiment of the present invention shown in FIG. 3, the pivoting mechanism (32) comprises a first follower (38), in mesh with the screw (30) and adjacent to a horizontal shaft (34), transversally and pivotally connected to the base (8). The lower end (18) of the first arm (14) is rigidly fixed to the ffrst shaft (34), therefore allowing to pivot the first arm (14) when pivoting said first shaft (34). The follower (38) is connected to the first shaft (34) via a pair of levers (40, 42). The flrst lever (40) has a first end (44) rigidly connected to the first shaft (34), and a second end (46) pivotally connected to a first end (48) of the second lever (42). The link is finally completed by a second end (50) of the second lever (42) pivotally connected to the first follower (38), preventing rotation of the same.
In this preferred embodiment, the apparatus (8) may further comprise a return spring (66), to provide counterbalance for the weight of the table (28) and the person thereon. The return spring (66) extends between a prolongation (68) of the first lever (40) from the second end (46), and a holding pin (70), located on the base (8) generally proximate its second end (12). A tension screw may be provided insteadof the pin (70) to apply tension to the return spring (66). The return spring (66) therefore biases the first and second arm (14,16) towards the upright position.
In a second preferred embodiment, shown in FIG. 4, a second follower (52) is provided, linked to a second shafl (36) in a manner similar as that described above.
The second shaft (36) is also transversally and pivotally connected to the base (8), and is rigidly connected to the lower end (22) of the second arm (16). The second follower (52) is also in mesh with the screw (30), and is and adjacent to the second shaft (36). A third lever (54), having a first and a second end (56, 58), is provided.
The first end (56) of the third lever (54) is rigidly connected to the second shaft (36), and the second end (58) is pivotally connected to a first end (60) of a fourth lever (62). This fourth lever (62) also has a second end (64) pivotally connected to the second follower (52) and preventing rotation of the same. In this embodiment, the return spring is connected to a prolongation (72) of the third lever (54) instead of the flrst lever (40).
The preferred manner of connecting the body-receiving table (28) to the rest of the apparatus (6) is better shown in FIG. 1. As illustrated, the first arm (14) preferably comprises an upper U-shaped portion (74), having two upper ends (20a,20b). Theseupper ends (20a, 20b) of the U-shaped portion (74) deflne the upper end (20) of the first arm (14). The horizontal connecting member (26) also comprises a U-shaped portion (76), which has two ends (78a, 78b) pivotally connected to the respective upper ends (20a, 20b) of the U-shaped portion (76) of the first arm (14). A pair of brackets (80) may be provided at the connecting points of the U-shaped portions (74, 76). The table (28) is connected to these brackets (80), by means of a sub-frame(84) under said table (28).
To provide leverage to maintain the table (28) in a tilted position, the apparatus (6) further comprises a support (82) selectively connectable between the horizontal connecting member (76) and the sub-frame (84) of the table (28). In a preferred embodiment shown in FIG.5, the support (82) may comprise a pre-loaded gas spring(86) supporting the table (28) and connected to the connecting member (26) through a rigid component (83). In this manner, the person supported by the apparatus (6) may control the tilting of the table (28) through a control handle (88).
The table (28) preferably comprises a flrst portion (100) and a second portion (102).
The flrst portion (100) is connected to the first arm (14) and support the user body thereon. The second portion (102) is in the upper part of the table (28), and is tiltable with respect to the first portion (100). With this feature, the second portion (102) may support the head of the person using the apparatus (6) when the table (28) is in the horizontal position. Once the table is tilted, the second portion (102) may then be also tilted and serve as a working area for the user of the apparatus (6). An adjustable supporting bar (104) is provided to support the second portion (102) in either the retracted or tilted position, as shown in FIG.1.
The person using the apparatus (6) is prevented from fal!ing by a series of adjustable straps (94), provided on the sldes of the table (28). Each of these straps (94) comprises a belt (96) attached to adjustable side body supports (98). An adjustable footrest assembly (105) is also provided for the comfort of the user of the apparatus (6). Preferably, a stem (108) is fixed on the sub-frame (84) of the table (28), at the end of which are connected footrests (106). The length of the stem (108) is adjustable by means of a sleeve (110) provided with adjustment holes (112), and a pin (114) to be inserted in a desired hole (112).
Although a preferred embodiment of the invention has been described in detail herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to this precise embodiment and that various changes and modifications may be effected therein without departing from the scope or spirit of the present invention.

The support apparatus (6) according to the present invention is for supporting aperson in a tilted or generally vertical position. As can be seen on FIG. 1, theapparatus (6) comprises an elongated and ground-engageable base (8), having a first end (10) and a second end (12). Advantageously, the base (8) may be provided with ground engageable wheels (116) supported by wheel supports (118), to facilitate transportation of the apparatus (6). To further stabilize the apparatus (6), a removable extended stabilizer (120) may also be provided.
A first arm (14) and a second arm (16) are pivotally connected to the base (8), both being pivotable in a vertical plane. The first arm (14) has a lower end (18) and an upper end (20), the lower end (18) being pivotally connected to the base (8) adjacent to its first end (10). The second arm (16) also has a lower end (22) and an upper end (24). The lower end (22) of the second arm (16) is pivotally connected to the base (8) at a location which is distal from the first end (10) thereof. In the illustrated embodiments, the distal location is about the center of the length of the base (8). The upper ends (20,24) of the first and second arms (14,16) are operatively joined by a horizontal connecting member (26) which is pivotally connected between the upperends (20, 24). The connecting member (26) thus ensures that both arms (14,16) are moved in a coordinated fashion when they are pivoted. These arms (14,16) and theconnecting member (26) provide a supporting assembly on which the body-receivingtable (28) is connected, as explained hereinafter. The pivot movement of the arms (14,16) moves the upper ends (20,24) in an arc-shaped movement with a vertical component. Thus, pivoting the arms (14,16) moves the upper ends (20,24) up and down, providing height adjustability to the table (28) connected thereto.
Advantageously, this feature allows to more easily set the person to be supported by the apparatus (6) on the table (28): For example, the height of the table (28) can be adjusted to extend flush with a bed or a sofa, and the user body can simply be rolled onto the table (28) with minimum efforts and attending personnel.
According to the present invention, the rotation of the first and second arms (14,16) is made possible by a screw (30) extending horizontally and longitudinally in the base (8) and pivotally connected thereto by means of bearings (31). A pivoting mechanism (32) links the screw (30) to at least one of the first and second arms (14, 16), to transform the rotation of the screw (30) in a pivot torque. The pivotingmechanism (32) further allows to lock in position said first and second arms (14,16).
The arms (14,16) are then moveable in any position between an upright position (FIG.1) and an inclined position (FIG.2). The screw (26) is operable either manually, by a crank (90) as show in FIG. 1, or with the help of an electrical motor (92) illustrated in FIG. 4. It should be noted that it is necessary to only directly connect one of the arms (14,16) to the screw (30), the other being then indirectly connected by means of the connecting member (26).
According to a preferred embodiment of the present invention shown in FIG. 3, the pivoting mechanism (32) comprises a first follower (38), in mesh with the screw (30) and adjacent to a horizontal shaft (34), transversally and pivotally connected to the base (8). The lower end (18) of the first arm (14) is rigidly fixed to the ffrst shaft (34), therefore allowing to pivot the first arm (14) when pivoting said first shaft (34). The follower (38) is connected to the first shaft (34) via a pair of levers (40, 42). The flrst lever (40) has a first end (44) rigidly connected to the first shaft (34), and a second end (46) pivotally connected to a first end (48) of the second lever (42). The link is finally completed by a second end (50) of the second lever (42) pivotally connected to the first follower (38), preventing rotation of the same.
In this preferred embodiment, the apparatus (8) may further comprise a return spring (66), to provide counterbalance for the weight of the table (28) and the person thereon. The return spring (66) extends between a prolongation (68) of the first lever (40) from the second end (46), and a holding pin (70), located on the base (8) generally proximate its second end (12). A tension screw may be provided insteadof the pin (70) to apply tension to the return spring (66). The return spring (66) therefore biases the first and second arm (14,16) towards the upright position.
In a second preferred embodiment, shown in FIG. 4, a second follower (52) is provided, linked to a second shafl (36) in a manner similar as that described above.
The second shaft (36) is also transversally and pivotally connected to the base (8), and is rigidly connected to the lower end (22) of the second arm (16). The second follower (52) is also in mesh with the screw (30), and is and adjacent to the second shaft (36). A third lever (54), having a first and a second end (56, 58), is provided.
The first end (56) of the third lever (54) is rigidly connected to the second shaft (36), and the second end (58) is pivotally connected to a first end (60) of a fourth lever (62). This fourth lever (62) also has a second end (64) pivotally connected to the second follower (52) and preventing rotation of the same. In this embodiment, the return spring is connected to a prolongation (72) of the third lever (54) instead of the flrst lever (40).
The preferred manner of connecting the body-receiving table (28) to the rest of the apparatus (6) is better shown in FIG. 1. As illustrated, the first arm (14) preferably comprises an upper U-shaped portion (74), having two upper ends (20a,20b). Theseupper ends (20a, 20b) of the U-shaped portion (74) deflne the upper end (20) of the first arm (14). The horizontal connecting member (26) also comprises a U-shaped portion (76), which has two ends (78a, 78b) pivotally connected to the respective upper ends (20a, 20b) of the U-shaped portion (76) of the first arm (14). A pair of brackets (80) may be provided at the connecting points of the U-shaped portions (74, 76). The table (28) is connected to these brackets (80), by means of a sub-frame(84) under said table (28).
To provide leverage to maintain the table (28) in a tilted position, the apparatus (6) further comprises a support (82) selectively connectable between the horizontal connecting member (76) and the sub-frame (84) of the table (28). In a preferred embodiment shown in FIG.5, the support (82) may comprise a pre-loaded gas spring(86) supporting the table (28) and connected to the connecting member (26) through a rigid component (83). In this manner, the person supported by the apparatus (6) may control the tilting of the table (28) through a control handle (88).
The table (28) preferably comprises a flrst portion (100) and a second portion (102).
The flrst portion (100) is connected to the first arm (14) and support the user body thereon. The second portion (102) is in the upper part of the table (28), and is tiltable with respect to the first portion (100). With this feature, the second portion (102) may support the head of the person using the apparatus (6) when the table (28) is in the horizontal position. Once the table is tilted, the second portion (102) may then be also tilted and serve as a working area for the user of the apparatus (6). An adjustable supporting bar (104) is provided to support the second portion (102) in either the retracted or tilted position, as shown in FIG.1.
The person using the apparatus (6) is prevented from fal!ing by a series of adjustable straps (94), provided on the sldes of the table (28). Each of these straps (94) comprises a belt (96) attached to adjustable side body supports (98). An adjustable footrest assembly (105) is also provided for the comfort of the user of the apparatus (6). Preferably, a stem (108) is fixed on the sub-frame (84) of the table (28), at the end of which are connected footrests (106). The length of the stem (108) is adjustable by means of a sleeve (110) provided with adjustment holes (112), and a pin (114) to be inserted in a desired hole (112).
