Combined standing and walking aid

The invention relates to a combined standing and walking aid for disabled people who cannot stand or walk under their own power or without support (e.g. paraplegics or spastic paraplegics), consisting of a base frame that carries a height-adjustable pelvic bar (5) to which a special device (pelvic apparatus) is attached to accommodate the pelvic area and a floor apparatus that can be hung in the base frame and is equipped with a device for fixing the feet and a knee support apparatus that is connected to the floor apparatus and is height- and depth-adjustable, as well as an attachable table and wheels, two of which are preferably electrically driven, the batteries (29) required for this are carried by a battery carrier (30) that is preferably attached to the front of the base frame. In order to enable disabled people to stand as required on a daily basis, which is necessary, for example, for training the circulation, emptying the upper urinary tract and preventing Contraction of the leg muscles is necessary, standing aids are known that have a similar basic structure.

The standing aids known to date are generally only used by one disabled person due to their relatively complicated adjustability; in addition, they can only be used as a standing aid. The standing and walking aid according to the invention can be used by several people thanks to its easy adjustability; the multiple uses as both a standing aid and a walking aid are achieved through quick and easy conversion; this seems particularly useful in facilities that care for several disabled people, who usually have related disabilities, but of different degrees.

The free-standing bars from Rollstuhl Richter GmbH & Co KG (Rail no. G 81 35 530.0) and the standing aid device from Dräger-Oehlert GmbH (Rail no. G 93 17 776.3) are particularly well developed. However, both devices have shortcomings in terms of ease of use and versatility of use, as well as in ergonomic aspects.

Both devices can be climbed into independently by users with active upper bodies, whereby in one case the user must put on a belt while sitting in the wheelchair, which encloses the buttocks area and fixes the user in the standing position in the pelvic area, in the other case the user must fold down a pelvic support located to the side of the standing position using a lever.

In the event that the disabled user of the device is not able to climb into the device under his or her own power, assistants are required to help with putting on the belt and during the uprighting process or when folding the lever for putting on the pelvic support.

The invention is based on the object of providing a standing aid that can be

Action by the user climbing onto the device during the boarding process closes and holds the user securely. This would avoid the relatively complicated fastening of the belt or the critical situation when turning the lever to fasten the pelvic support, in which the user can only hold on with one hand, which means destabilization of the stability, and would simplify the boarding process. It would also relieve any helpers that might be required or reduce the number of people required. The device according to the invention with pelvic shells (8) and pelvic belt (9) makes this possible by the pelvic shells (8) being opened before climbing onto the standing aid, so that the user can climb into the standing aid from behind. The pelvic belt (9) is now between the pelvic shells (8). If the user now pulls himself into the standing aid using the pelvic bar (5), he hits the pelvic belt (9) in the hip area and tightens it. The further the user pulls forward, the further the lap belt (9) is tensioned or pulled forward, so that the lap belt (9) takes the pelvic shells (8) to which it is attached with it. These close behind the user more and more until they lock into a certain position and the user is held firmly between the lap belt (9) and the pelvic shells (8). This means that the user never has to give up their secure grip on the pelvic bar (5) in order to operate a mechanism, for example, and they do not have to put on a belt beforehand, which is cumbersome and time-consuming for assistants. One assistant is sufficient; they only have to help the user to stand safely and no longer need to operate a mechanism.

The devices known to date are very difficult to adjust in the pelvic area. It is necessary to unscrew a clamping screw on two support tubes. Only then can the pelvic support be moved up or down, but it must be held in the desired position with one hand and both screws must be tightened again with the other hand, i.e. you need two fully functional arms and hands to adjust the support.

The object of the invention is to provide a standing aid in which the height of the pelvic support can be adjusted with one hand. The standing and walking aid according to the invention makes this possible in that the pelvic support is guided via a telescopic column with only one inner and outer tube (4 and 3). This telescopic column, which is attached to the front area of the base frame, receives the pelvic bracket (5) to which the pelvic shell supports (J) are attached via a connecting element (6). The telescopic column is preferably held in place by a gas pressure spring which is provided with a locking mechanism. If the height adjustment release lever (33) is operated, the lock is released and the entire pelvic apparatus is pushed slightly upwards with the support of the gas pressure spring. By pressing the pelvic apparatus downwards, the distance between the base plate (20) and the pelvic shells (8) is shortened. Since there is only one lever and only one telescopic column, adjusting with one hand is no problem.

The devices known to date use a continuous foam pad as a knee support, which is provided with vertical recesses for the knee areas and thus prevents sideways slipping. With such a device for supporting the knees, the main pressure load is on the kneecaps, as the front part of the knee, which is unfavorable from an anatomical point of view, since they are not designed for such loads.

To compensate for the depth of a person's legs being stretched out at different distances, the knee pad can be rotated around a vertical axis in the known devices, whereby the

The direction of the knee pad in relation to the user's body changes, which means that an anatomically optimal shape of the knee support is only possible to a limited extent, that the support function to the side is negatively affected and that the extreme adjustments that this arrangement allows are relatively close to one another. The height and depth adjustment of the knee support on the known standing aids is ensured by guides with locking pins that can be unlocked by pulling on a knob attached to them or by guides with clamping screws, which means that the device can only be operated with two hands that must be fully functional. One hand must operate the release pin or the clamping screw, the other holds the knee support to be adjusted. Depth adjustment in the knee area is not possible at all by the disabled person while the device is being used, and by an assistant it is only possible with considerable effort and with a loss of stability for the disabled person. The steep elements are usually located under the fixed table and are therefore difficult to access. The invention is based on the task of providing a standing aid that enables the knee height and depth to be adjusted with one hand, whereby the user should also be able to adjust the knee depth while in the standing aid, in order to make the standing aid more flexible to short-term changes in condition (e.g. spastic cramps, stretching success, daily form) and to ensure more precise adaptation to the requirements of the therapy. In addition, the knee supports should be shaped in such a way that the kneecaps are not unnecessarily stressed and the already weakened ligaments of the knee are supported.

The knee support device according to the invention makes this possible by being suspended from a guide rail (11) on which its height can be adjusted by means of a locking mechanism that is unlocked and released via a knee support support release button (18). This knee support release button (18) is attached to the knee support support (12) in such a way that it can be operated with the hand with which the knee support device is held. Two parallelogram levers are attached to the knee support support (12), each of which can be adjusted in depth independently of one another using a rotary knob (14). This is easily possible thanks to the low thread pitch of the thread (143) while the user is in the standing aid. A knee support (17) is connected to each of the parallelogram levers, which is shaped in such a way that it engages just above and just below the knee joint and thus does not exert any pressure on the kneecap.

The previously known devices use a band to fix the foot, which is attached to the base plate and cannot be moved. It can only be adjusted to the respective foot size by loosening or tightening. This band prevents the foot from being pulled upwards and forwards. To ensure that the foot does not slip backwards, a shell is attached that encloses the heel and is pushed into holes in the base plate with two pins. The holes are arranged in a row running from front to back so that different foot sizes can be compensated. The previously known devices do not make it possible to compensate for incorrect leg or foot positions. The invention is based on the object of providing a standing aid that makes it possible to fix the foot freely on the base plate (20) in order to compensate for any incorrect leg positions. The heel cup (22) according to the invention makes this possible in that the foot securing strap (23) for fixing the foot upwards and forwards is attached to the heel cup (22) and thus the foot is firmly connected to the heel cup (22) and thereby,

that the base plate (20) is provided with a hole pattern covering the entire surface so that the heel cups (22) can be freely inserted into this pattern. Inserting or removing the heel cup (22) from the base plate (20) upwards is only possible by first tilting the heel cup backwards, due to the shape of the locking pins (1001).

Some of the devices known to date can only be moved by assistants; they usually have castors on the four corners of the base frame. Others can be driven by the disabled person themselves using muscle power or electrically, whereby the previously known, driven standing aids are so large due to the arrangement of the elements that they are not very maneuverable. These devices also do not allow for adaptation to misalignments of the limbs or special therapeutic requirements and have the above-mentioned disadvantages in an even more obvious form with regard to the fixation of the user. The invention is based on the object of providing a standing aid that enables disabled people to move freely and under their own control with the device, for example to do housework or to use machines during vocational training and practice. The standing aid according to the invention makes this possible by having wheels attached to the four corners of the base frame, the wheels attached to the rear corners are caster wheels (26), the front wheels (27) are rigidly connected to the base frame and are preferably driven by electric motors. The front wheels (27) are driven separately from one another so that curves can be negotiated using different drive speeds. If only one front wheel (27) is operated, the standing aid therefore rotates around the non-driven wheel, which is not a problem thanks to the caster wheels (26) attached to the rear, just as reversing and turning on the spot are not. The selected attachment of the front wheels (27) means that the standing aid can be driven very close to tables, sideboards, etc. The user controls the standing aid or the motors using a control unit (31) attached to the pelvic support (5).

The devices known to date are equipped with tables that are mounted on a height-adjustable frame in front of the user. This frame is difficult to adjust and dismantle.

The invention is based on the object of providing a standing aid whose table can be adjusted and assembled or disassembled with one hand. The table according to the invention makes this possible by mounting a support structure on the table top (34) consisting of two table tubes (35) running parallel to one another and approximately perpendicular to the table top (34), which are attached under the table top (34), which can be inserted through two holes located on the connecting element (6), pelvic bracket (5) or the inner tube (4) of the telescopic column. A locking block (36) is attached to the parallel table tubes (35) in such a way that it can be moved on the table tubes (35) and is secured by an integrated eccentric clamp, the table tubes (35) can only be pushed through the holes until the locking block (36) prevents this, to adjust the table height the eccentric lever is released, to assemble or disassemble the table tubes (35) are simply pushed into or pulled out of the holes.

The previously known standing aids can only be used as standing aids. The invention is based on the task of providing a standing aid that allows multiple uses; because of the close connection between standing and walking,

the combination of standing and walking aid. The standing and walking aid according to the invention makes this possible because the base plate with the knee support device connected to the base plate can be removed from the original standing aid, so that the standing surface is eliminated and the user has direct contact with the ground with his feet. The lap belt (9) is replaced or extended by a seat belt (801), which is also attached to the pelvic shells (8), so that the user does not fall over when tired or has other problems, but his weight is caught by the seat belt (801) and he only needs to balance himself with his hands on the pelvic bar (5). In addition, the accumulators (29) can be removed to reduce the weight.

An embodiment of the invention is shown in the drawings and is described in more detail below.

Combined standing and walking aid for disabled people and those undergoing rehabilitation. The device is built on a preferably U- or H-shaped base frame, the base frame consists of a crossbar (2) and two side bars (1), casters (26) are attached to the rear, open side of the base frame and wheels (27), preferably driven by electric motors, are attached to the front, closed side. The wheels (27) are driven separately to enable cornering at different running speeds. In order to drive the electric motors, two accumulators (29) are attached to an accumulator carrier (30) in the middle, on the front of the crossbar (2). In the middle, on the back of the crossbar (2), the outer tube (3) of a telescopic column is attached vertically, the inner tube (4) of the telescopic column can be easily moved upwards using a spring (preferably a gas pressure spring) and can be easily moved downwards using pressure. A connecting element (6) is attached to the upper end of the inner tube (4) of the telescopic column, which in turn accommodates a U- or V-shaped pelvic bar (5). Pelvic shell supports (7) are attached to both ends of the pelvic bar (5), each with a joint that can be rotated around a vertical axis. Padded pelvic shells (8) are attached to the pelvic shell supports (7), to which a pelvic belt (9) is connected on the side facing forward in a length-adjustable manner. The pelvic belt (9) is pushed from the front into openings provided for this purpose through the pelvic shells and passes through the pelvic shell supports on the back.

(7) where it is fixed by eccentric clamping lever (10). A seat belt (801) is hooked into the lap belt and the pelvic shells. Two release levers (32 and 33) are attached to the pelvic bracket (5) near the connecting element (6), one for adjusting the height of the telescopic column and one for unlocking the pelvic shells, and the control unit (31) for the drive is also slidably attached to the pelvic bracket (5). In the state described so far, the device can be used as a walking aid, as shown in Fig. 8. To make things easier, the batteries can be removed.

In order to be able to use the device as a standing aid, as shown in Fig. 7, a ground device is hung in the base frame and the seat belt (801) is removed. The ground device is hung in two openings with hook pins in the outer telescopic tube (3) and two eyelets (25) on the side bars (1) with hooks (24). The ground device: consists of a base plate (20) under which a crossbar runs, the ends of which are designed as hooks (24). On the top side of the base plate (20) a base plate support (19) is attached lengthways in the middle, to which a guide rail (11) is attached vertically. The guide rail (11) is designed on its front side so that it fits snugly against the outer tube (3) of the telescopic column when the hook pins engage in the openings. The guide rail is on the back.

(11) designed in such a way that it can accommodate a knee support device in such a way that it can be moved on it. To reinforce the longitudinal support guide rail construction, a tension strut (21) is attached diagonally between the base plate support (19) and the guide rail (11). The knee support device consists of a slide rail that is slidably attached to the guide rail (11), the knee support support (12) is attached vertically to the slide rail with the knee support support release button (18). Two pairs of parallelogram arms are movably attached to the free end of the knee support support (12), at the ends of which a knee support receiver (15) with a buffer (16) and a padded knee support (17) is attached. The pairs of parallelogram arms can each be adjusted using a rotary knob (14) with a threaded spindle (141). The height of the entire knee support apparatus is adjusted by operating the knee support release button (18) and moving the slide rail against the guide rail (11)

The base plate (20) is provided with a hole pattern into which the locking pins (1001) with lugs (1002) of the heel cups (22) are inserted, as shown in Fig. 10 and 11. A boarding process without an assistant is shown as an example in Fig. 4-6. If assistants are required, they can help the disabled person to stand up in the device.
