Description

The present invention relates to a walking aid with a positioning device. Walking aids do not exclusively include a walking stick, a hand stick, a forearm crutch and an armpit support.

Walking aids are used by disabled or frail people to support them when walking and to support them in everyday life. The disability can also be limited in time, such as an injury. A walking stick usually consists of a support tube or rod made of metal (stainless steel), wood or plastic, at the upper end of which a handle and at the lower end a rubber foot for better grip when propping up are attached. Such walking sticks are well known.

The problem with a conventional walking aid, such as a walking stick, is that you cannot simply put the walking stick down when you want both hands to remain free, but always need an opportunity to lean against it or put it down. If the cane is ajar, there is always the risk that the cane will fall over, which can be a problem for people with walking difficulties or frailty. Therefore, numerous walking sticks have already been proposed which have a parking aid / standing device.

Such walking sticks generally have a standing device, which is designed for example in the form of a plate or in the form of lateral supports attached to the walking stick. A plate-like stand device is, for example DE 3112 315 A1 known.

The disadvantage of the walking sticks known from the prior art is that the standing device is very bulky and can possibly lead to accidents while walking. For example, plates protrude far from the walking stick and can therefore be in the way of a person when walking. Another problem with plate-like standing devices is that when the cane is put on while walking, the plate is usually first put on and then a high pressure from above can lead to the plate slipping off, which consequently no longer provides adequate support and the Person can fall seriously. Particularly on smooth surfaces, a load should only be applied when the panel is in full contact with the floor. In the case of uneven surfaces, the problem arises that, due to the large area of the plate, no surface contact can be made with the floor, so that the person can slip and thus fall, especially while walking.

In contrast, the object is to provide a walking aid with an erection device which eliminates the problems of the prior art and represents an alternative solution to the known walking aids.

• - das Stützelement an einem oberen Endabschnitt einen Griff und an einem gegenüberliegenden unteren Endabschnitt einen Standfuß aufweist,
• - das erste Halteelement fest in einem unteren Bereich an dem Stützelement angeordnet ist und eine der Anzahl an Streben entsprechende Anzahl an Öffnungen aufweist,
• - das zweite Halteelement beabstandet zu dem ersten Halteelement über dem ersten Halteelement in Richtung des ersten Halteelements verlagerbar an dem Stützelement angeordnet ist,
• - an dem zweiten Halteelement ein erstes Ende der Streben angeordnet ist und die Streben nach unten hin durch die Öffnungen des ersten Halteelements geführt sind, und
• - die Streben einen Knick im Wesentlichen in der Mitte aufweisen, so dass bei einer Verlagerung des zweiten Halteelements in Richtung des ersten Halteelements die Streben aus einer ersten Position, in welcher sich der Knick der Streben im Wesentlichen mittig zwischen dem ersten Halteelement und dem zweiten Halteelement befindet, in eine zweite Position verbringbar sind, in welcher der Knick sich in der Nähe des ersten Halteelements befindet, so dass die freien zweiten Enden der Streben von dem Stützelement abstehen und Stützen ausbilden.

To achieve the above-mentioned object, the invention proposes a walking aid with an erection device, the walking aid having at least one rod-shaped support element and the erection device having a first holding element and a second holding element as well as at least two pairs of opposing struts, wherein

• the support element has a handle at an upper end section and a stand at an opposite lower end section,
• - The first holding element is fixedly arranged in a lower area on the support element and has a number of openings corresponding to the number of struts,
• the second holding element is arranged on the support element at a distance from the first holding element above the first holding element in the direction of the first holding element,
• a first end of the struts is arranged on the second holding element and the struts are guided downward through the openings of the first holding element, and
• - The struts have a bend essentially in the middle, so that when the second holding element is displaced in the direction of the first holding element, the struts from a first position in which the bend of the struts is essentially centered between the first holding element and the second holding element located, can be brought into a second position in which the bend is located in the vicinity of the first holding element, so that the free second ends of the struts protrude from the support element and form supports.

In the first position, which represents the position of use during walking, the struts are retracted and run essentially parallel to the rod-shaped support element. In this state, the struts do not protrude from the support element and therefore hardly take up any space, so that the walking aid is not bulky while walking and possible accidents are avoided. In the first position, when the walking aid is put on while walking, the force transmitted by a person to the handle is diverted to the floor via the rod-shaped support element.

The first holding element and the second holding element are arranged on the support element, the second holding element being displaceable (e.g. can be moved). In the first position (position of use when walking) the struts extend between the first holding element and the second holding element in such a way that the section of the struts with the bend is located essentially centrally between the holding elements.

In this position, the free second ends of the struts can protrude only slightly from the openings of the first holding element. When the walking aid is used properly, which excludes possible repair and maintenance work, the free second ends are never displaced so far that they pass through the openings in the first holding element, ie are pushed into the section between the first holding element and the second holding element . The struts are therefore always guided over the openings in the first holding element. In the first position, the installation device takes up little space and the walking aid can be used like an ordinary walking aid. There are no restrictions in terms of applicability and no restrictions in terms of freedom of movement for the user.

• - zwar immer noch zwischen dem ersten Halteelement und dem zweiten Halteelement verläuft, aber soweit dem ersten Halteelement angenähert ist, dass die freien zweiten Enden der Streben vom Stützelement abstehen,
• - sich auf Höhe der Öffnungen des ersten Halteelements befindet, so dass die freien zweiten Enden der Streben vom Stützelement abstehen, oder
• - die Öffnungen des ersten Halteelements passiert hat, wobei der Abschnitt der Streben mit dem Knick nicht mehr zwischen dem ersten Halteelement und dem zweiten Halteelement verläuft, so dass die freien zweiten Enden der Streben vom Stützelement abstehen.

In order to have both hands free, the erection device of the walking aid can be operated so that the walking aid can be parked. For this purpose, the second holding element is shifted downwards in the direction of the first holding element, whereby the struts are pressed downwards in the same direction. The struts are guided through the openings of the first holding element and the section of the struts with the bend is displaced in the direction of the first holding element until the section of the struts with the bend

• - although it still runs between the first holding element and the second holding element, but the first holding element is approximated to the extent that the free second ends of the struts protrude from the support element,
• - Is located at the level of the openings of the first holding element, so that the free second ends of the struts protrude from the support element, or
• - Has passed the openings of the first holding element, the section of the struts with the kink no longer running between the first holding element and the second holding element, so that the free second ends of the struts protrude from the support element.

The free second ends can protrude in various ways, as described above. It is also possible for the free second ends of the struts for a walking aid to protrude in all three different variants, in which case the height of the walking aid in the second position is of course adapted to the position of the sections of the struts with the kink. The protrusion of the free second ends depends on how far the kink was shifted.

The kink means that the lower free ends of the struts protrude from the support element due to the kink and provide a large footprint that extends over the at least four support points of the free second ends. Overall, the support element is lifted, as a result of which the walking aid does not sit on the stand.

The kink is decisive for the fact that the struts want to adopt the orientation of the upper section and the lower section given by the kink. In the first position, however, this is prevented by being supported by the first holding element and the second holding element.

After the struts have been extended, the walking aid can be safely parked without tilting. In further embodiments, several pairs of struts can be provided, in which case several openings are also required in the first holding element. For example, three, four, five, six or even more pairs of struts can be provided.

Compared to a plate-shaped installation device from the prior art, the advantage is that a secure stand is guaranteed even on uneven surfaces. It is also advantageous that the base itself is also raised and therefore does not lie in a plane spanned by the at least four free second ends. This has the advantage that protrusion on uneven surfaces can be improved because the central base does not come into contact with the surface. The contact points are therefore only at the outer points of the "installation level". In the middle of the "installation level" there is no contact surface with the floor, so that the "installation level" cannot be reduced by the base.

To bring them into the first position, the struts are pulled upward away from the first holding element by moving the second holding element. The struts are essentially displaced to such an extent that the section of the struts with the bend is received centrally between the first holding element and the second holding element.

The lower ends of the struts are advantageously spread apart automatically by the displacement of the second holding element. The struts are also “retracted” through the relocation of the second holding element in the opposite direction.

The struts run on the outside of the support element so that they are visible. This enables intuitive actuation of the erection device because the mode of action is visible. This prevents incorrect operation.

The walking aid can, for example, be designed as a walking stick, hand stick, forearm crutch or armpit support and has appropriately designed handles and / or support elements for this purpose. The base can be made of a plastic or a rubber-like material according to the desired design. Other materials can also be used in further designs.

The struts themselves can preferably be made of metal. In further embodiments, a spring steel can be used for the struts, the struts themselves not being bendable, so that the kink is retained even when the erecting device is retracted. The material of the struts must also be sufficiently stable to be able to hold the walking aid when it is set down. Since when the walking aid is in the parked state (second position) there is generally no support by a person, the struts can have a small thickness.

In the second position, the struts can protrude from the support element at an angle of 10 ° to 25 ° due to the kink. This also corresponds to the alignment of the upper sections of the struts with the lower sections of the struts. For this purpose, the kink of the struts is formed at a corresponding angle. The angle of the kink and the angle at which the struts protrude from the support element in the second position is to be selected so that a relatively large area is provided over the free ends of the struts. However, the angle must not be too large, so that, on the one hand, the struts themselves in the second position, especially in the area of the bend, are not damaged when a force acts on the walking aid, and on the other hand, the struts in the first position in the area of the bend are not stretched too much.

The support element can have a rod or a tube or be designed as a rod or tube. The design of the support element depends on the use of the support element and in particular the walking aid. Often pipes are used because they can dissipate a greater force without being deformed or damaged. Metals, composites, plastics, wood and natural materials such as bamboo, for example, can be used as the material for the support element.

The support element can be designed in two parts, the two support element parts being displaceable relative to one another. This enables the height of the walking aid to be adapted to people of different heights or their habits.

In further embodiments, the handle, the first holding element and the second holding element can be arranged on an upper support element part and the base can be arranged on a lower support element part, the lower support element part being slidable into the upper support element part. This design has the advantage that the installation device itself can be used regardless of the respective height. For this, it must be taken into account that the struts have a corresponding length so that the walking aid can be set down over the at least four contact surfaces of the free second ends of the struts even at the maximum possible height in the second position of the erection device.

The depth of insertion of the lower support element part can be adjustable via a screw connection or a latching connection. In the embodiment with a latching connection, the upper support element part has a plurality of openings which extend along the longitudinal axis of the support element. The lower support element part has an outwardly protruding latching button which is pressed into the openings of the upper support element part via a spring. Depending on the desired height, the locking button protrudes into one of the openings. In order to change the height, the latching button is pressed in and the lower support element part is moved until the latching button is received in the corresponding opening in the upper support element part for setting the desired height.

In the case of a screw connection, the lower support element part and the upper support element part can be rotated with respect to one another. The rotation in a first direction causes a release of the connection and the rotation in the opposite direction about the longitudinal axis of the support element causes a locking. This design has the advantage that no fixed heights are specified, but the walking aid can be continuously adjusted to different heights.

The free second ends of the struts can have a cover or a cap in order to prevent the walking aid from slipping or tipping over in the second position. In addition, a cover or a cap can protect the free second ends of the struts, especially those made of metal, from damage and soiling. The subsurface can also be protected from damage (e.g. scratching), especially in the case of metal struts. The coating or the Cap can be made of plastic or a rubber-like material and thus of the same material as the base. Other suitable materials can therefore also be used.

The first ends of a pair of opposing struts can be connected to one another via a substantially horizontally extending connecting section and can be arranged in the second holding element. In such an embodiment, the pairs of opposing struts can consist, for example, of a rod which is bent over essentially orthogonally in the region of the first ends. It can also be a strut wire that is bent twice. The bent sections are located in the second holding element. The bent sections are connected via the connecting section. The upper sections of the struts are then led out through the openings in the second holding element. This embodiment has the advantage that the alignment of the struts is maintained in all positions and lateral tilting is prevented. In the first position, the upper section and the lower section of the struts are braced against one another due to the kink which tries to push the upper section and the lower section apart.

The first holding element and the second holding element can be annular and surround the support element. Holding elements designed in this way enable simple implementation and facilitate operation, since, for example, the struts can be displaced simultaneously and evenly over the circumference of the support element.

In further embodiments, the second holding element can consist of two half-sockets screwed against each other and form a cavity in which the first ends of the struts are received, the first holding element being a half-socket open in the direction of the base. The bent-over sections and the connecting section, for example of a strut wire, can be accommodated in the cavity.

The walking aid according to the invention enables the struts to be extended by moving the second holding element, whereby a large set-up area is provided by the struts "spreading open" due to the kink. The second holding element can then just as easily be shifted again in the opposite direction along the support element, the struts returning to their starting position in which the struts extend essentially parallel to the support element or are in contact with the support element.

Elements provided with the same reference symbols in the drawings essentially correspond to one another, unless otherwise indicated. In addition, there is no need to show and describe components that are not essential for understanding the technical teaching disclosed herein. In the following, the reference symbols are not repeated for all elements that have already been introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art.

1 shows a schematic representation of a walking stick 100 trained walking aid with a positioning device in a first position, the walking stick 100 can be used in its original function.

The walking stick 100 has a support element 30th on. The support element 30th consists of an upper support element part 32 and a lower support member portion 36 , wherein the lower support member part 36 in the upper support element part 32 is retractable. The upper support member part 32 has openings 34 on. In these openings 34 a latching button can penetrate, which is pretensioned by a spring on the lower support element part 36 is arranged. This allows the insertion depth of the lower support element part 36 in the upper support element part 32 change and adjust. In the embodiment shown, the support element part 32 three openings 34 so that three different height adjustments can be made. The locking button engages in one of the three openings 34 so that the lower support element part 36 different far from the upper support element part 32 protrudes.

The upper support member part 32 ("Support tube") is tubular. The lower support member part 36 can be designed either as a tube or as a rod, a tubular design having the advantage of low weight with high stability and strength. The upper support element part 32 and the lower support member part 36 can preferably consist of a metal, such as aluminum, or a metal alloy. In further embodiments, other materials and materials can also be used for the support element parts 32 and 36 be used.

On the lower support element part 36 is a stand 20th appropriate. The stand 20th consists of a rubber-like material and is used to prevent slipping when supporting on the walking stick 100 to prevent. The stand 20th has for this purpose a larger area at its lower end.

At the upper end of the upper support element part 32 is a handle 10 arranged. When running as a walking stick 100 points the handle 10 a corresponding shape so that the handle 10 can be easily grasped by one person. The handle 10 can consist of a material or a mix of materials which, for example, is elastically deformable on the outer surface so that it can be easily pressed in. This is used to hold the handle 10 adapt for different people and their behavior. The handle 10 is designed in particular so that this is a transfer of the force applied by a person to the support element 30th and also does not cause any injuries (e.g. pressure points) or pain in the user's hand even with prolonged use. The handle 10 be ergonomically shaped.

In further non-illustrated embodiments of a walking aid, the handle can be designed differently. For example, a forearm crutch has a handle and a higher-lying cuff which rests on a person's forearm and defines the orientation of the forearm crutch. The cuff prevents it from kinking to the side or back.

The erection device comprises a first holding element 40 , a second holding element 50 and striving 60 . The first holding element 40 is designed as a half bushing and surrounds the upper support element part in a ring shape 32 on a lower portion of the upper support member part 32 , as in 1 and 2 indicated schematically. The first holding element designed as a half bushing 40 is oriented so that the opening of the socket is facing down towards the stand 20th shows. In the first position, which is in 1 shown, lower free ends are provided across the side walls of the socket 66 of striving 60 with caps 68 essentially covered and thus also protected. In further embodiments, not shown, the free ends 66 with the caps 68 via a holding element designed as a half bushing 40 stand out and therefore be visible and accessible from below. In addition, in further embodiments, not shown, the first holding element can be designed differently.

The first holding element 40 is ring-shaped and surrounds the upper support element part 32 . The first holding element 40 has in the ring section which the support element part 36 surrounds, openings through which lower sections 65 of striving 60 are led. These openings extend circumferentially evenly around the upper support element part 32 . The number of openings in the lower support element 40 corresponds to the number of struts 60 . The openings are spaced from the upper support element part 32 and are therefore on the outer edge of the first holding element 40 arranged.

The first holding element 40 is fixed in the lower portion of the upper support member 32 arranged and cannot be relocated.

The second holding element 50 is also annular and surrounds the support element part 32 . The second holding element 50 is displaceable, in particular displaceable, on the upper support element part 32 arranged. In the first position ( 1 ) is the second holding element 50 at a central portion of the upper support member part 32 . The second holding element 50 has two sockets 52 and 54 on that about screws 70 are connected to each other (see 3rd ). A lower socket 54 and an upper socket 52 are designed as half sockets. The lower socket 54 has openings 56 on through which the upper sections 61 of striving 60 are led. In the one between the sockets 52 and 54 formed cavity are first ends 62 of the upper section 61 of striving 60 recorded. The striving 60 are formed by a strut wire in the area of the second holding element 50 is bent twice by 90 °, as in 3rd shown. Two opposite struts 60 are formed from a strut wire and form a pair of opposing struts 60 .

A displacement of the second holding element 50 downward therefore also leads to the striving 60 be moved down. The first ends 62 of striving 60 cannot come out of the second holding element due to the bent-over sections 50 emerge and are therefore inevitably connected to the second holding element 50 coupled and held securely in it.

The second holding element 50 points to the lower socket 54 one of the openings in the first holding element 40 and the number of struts 60 corresponding number of openings 56 on. The openings 56 are essentially the openings in the first holding element 40 across from.

The first holding element 40 and the second holding element 50 can preferably consist of a metal or a metal alloy in the embodiment shown and are therefore resistant to external influences.

The striving 60 have an upper section 61 and a lower section 65 on. Between the upper section 61 and the lower section 65 show the striving 60 a kink 64 on. The kink 64 is located essentially centrally along the struts 60 and divides the upper section 61 and the lower section 65 essentially in two equal parts. The kink 64 is essential to the fact that the upper section 61 and the lower section 65 are inclined to each other. The angle between an imaginary extension of the upper section 61 down and the lower section 65 can be between 10 ° and 25 °.

The striving 60 are preferably made of metal. In particular, there are struts 60 made of a spring wire and cannot be deformed themselves, so that the kink 64 is maintained even when the erection device is retracted. In the first position ( 1 ) are the lower sections 65 in the area of the second free ends 66 in the openings of the first holding element 40 recorded. The top first ends 62 are in the second holding element 50 as described above and in 3rd shown. This allows the struts 60 not from the support element part 32 stick out. The storage of the struts 60 in the openings 56 or in the opening of the holding element 40 prevents the struts from sticking out 60 in the first position. Because of the kink 64 are the striving 60 compared to a set-up position (second position) between the first holding element 40 and the second holding element 50 curious; excited. The striving 60 are stretched in the first position, as the support of the struts 60 an alignment of the two sections in the corresponding openings 61 and 65 prevented. That is, the alignment of the struts 60 in the first position does not correspond to the original orientation and the struts 60 are excited.

In the embodiment shown, the walking stick 100 four struts 60 or two pairs of opposing struts 60 for the installation device. Accordingly, the lower socket 54 four openings 56 and the first holding element 40 also has four openings through which the lower sections 65 of striving 60 are led.

2 shows a schematic representation of the walking stick 100 in the second position, with the positioning device actuated and the walking stick 100 can be turned off by means of the erection device.

The second holding element 50 is in this position starting from the starting position in 1 downwards in the direction of the first holding element 40 relocated. For this purpose, the second holding element 50 gripped by a person and along the upper support element 32 be pushed down. The displacement of the second holding element 50 also causes a shift in the struts 60 , the section with the kink 64 got down. Doing the lower sections 65 of striving 60 from the openings in the first holding element 40 and start due to the kink 64 to the side of the support element 30th to withdraw. The location of the lower sections 65 specifies whether and how far the free second ends 66 from the support element 30th or from an imaginary extension of the support element 30th stick out.

A sticking out of the lower sections 65 as well as the free ends 66 can take place, for example, when the sections with the kink 64 still between the first holding element 40 and the second holding element 50 are located, but the first holding element 40 have approximated. Approximate means that the sections with the kink 64 in close proximity to the first holding element 40 can be located. In addition, a protrusion can also be achieved when the section of the struts 60 with the kink 64 essentially at the level of the openings in the first holding element 40 or as in 2 shown, the openings in the first holding element 40 have already passed and are a little way below the first retaining element 40 are located. Here are the upper sections 61 of striving 60 through the openings in the first holding element 40 guided and corresponding to the opposite openings 56 aligned. The lower sections 65 stand in a star shape from the support element 30th from.

The displacement of the second holding element 50 therefore automatically leads to a shift in the struts 60 and spreading the lower sections apart 65 so that over the free ends 66 a large area for the walking stick 100 provided.

The free second ends 66 each have a cap 68 on that on the second ends 66 is attached. The caps 68 can be made of the same material as the base 20th and on the one hand protect the free ends 66 as well as the surface on which the walking stick is placed 100 is set up.

2 also shows that the stand 20th by shifting the struts 60 is spaced from the ground.

For spending the walking stick 100 from the second position ( 2 ) to the first position ( 1 ) only needs the second retaining element 50 be shifted upwards in the opposite direction, the struts 60 be carried along and due to the kink 64 between the first holding element 40 and the second holding element 50 take up the tense position. The free ends also get here 66 from the spread position to a close to the upper support element part 32 current position. In the first position the struts 60 also partially on the upper support element part 32 between the first holding element 40 and the second holding element 50 issue.

3rd shows a schematic representation of a portion of the walking stick 100 with the second holding element 50 of the erection device in a partially sectioned view. In 3rd can the second holding element 50 e.g. in the second position ( 2 ), with the upper sections 61 parallel to each other and parallel to the upper support element part 32 run away.

3rd shows a possible design of the second holding element 50 coming out of an upper socket 52 and a lower socket 54 consists. The two sockets 52 and 54 are about screws 70 and nuts 72 screwed so that the first ends 62 or the bent sections and the connecting section of the struts connecting these sections 60 in the cavity between the sockets 52 and 54 being held. The connecting portion of a strut wire lies under the connecting portion of another strut wire. This must be done with the selection and arrangement of the struts 60 be taken into account so that the free second ends 66 lie essentially in one plane in the second position. To do this, the lengths of the struts 60 be different accordingly.

The illustration shows the design of the sockets 52 and 54 as well as the ends 62 only exemplary. Therefore, the height of the through the sockets 52 and 54 formed cavity also be approximately only as large as the height of the first ends 62 or the bent sections. The size of the cavity must be a displacement according to the movement of the struts described herein 60 enable. A shift in the second holding element 50 , especially in the longitudinal direction of the support element 30th , however, should not occur and is due to the encapsulated design of the second holding element 50 prevented.

The openings 56 and the openings in the first retaining element 40 are preferably circular. This prevents the struts from tilting 60 in the respective positions and when moving the struts 60 from the first position ( 1 ) to the second position ( 2 ) and vice versa. In particular, the diameter of the openings 56 and the openings in the first retaining element 40 essentially as large as the width of the struts 60 . The striving 60 can, for example, have a round cross-section, so that the diameter of the openings 56 and the openings in the first holding element 40 can only be slightly larger than the diameter of the struts 60 to make a shift in pursuit 60 to be made possible in the manner described above. The striving 60 but can also have a rectangular cross section, so that the diameter of the openings 56 and the openings in the first holding element 40 can only be slightly larger than the greatest width of rectangular struts 60 .

The size of the openings in the first retaining element 40 also determines when the lower sections start 65 and the free second ends 66 begin to spread. The larger the diameter of these openings, the more likely it is when the second holding element is displaced 50 downward spreading occurs because the outer boundary or the outer contact point in the openings in the first holding element 40 from the center of the first holding element 40 from the point of view of moving further outwards. It must also be taken into account that the arrangement of the openings and their distance from the center of the first holding element 40 The decisive factor is when spreading occurs.

4th shows a schematic representation of the second holding element 50 facing the underside 53. In this illustration is the arrangement of the screws 70 as well as the nuts 72 and the openings 56 shown. The striving 60 extend evenly distributed around the circumference of the second holding element 50 . The first holding element 40 is constructed similarly and also has a ring that forms the upper support element part 32 surrounds. The openings of the first holding element are located here 40 the openings 56 of the second holding element 50 opposite, so that in the extended position of the erection device (second position - 2 ) the struts 60 star-shaped from the upper support element part 60 stand out and because of the kink 40 a spreading of the lower free second ends 66 effect.

The erection device can be set up by sliding the second holding element up and down 50 be retracted and extended. When extending, the second retaining element 50 pressed down, reducing the struts 60 over the openings of the first Retaining element 40 evade out downwards. As soon as the in pursuit 60 included kink 64 the first holding element 40 approaching, the striving begin 60 , especially the lower sections 65 to move outward over the bottom of the walking stick 100 to spread away and thus form a set-up device. In other versions, the spreading can only take place when the kink 64 the lower openings in the first holding element 40 happened. The stand becomes 20th of the walking stick 100 raised. Becomes the second holding element 50 pushed up again, the struts pull themselves 60 one and the stand 20th of the walking stick 100 can be placed on the floor again. Are the aspirations 60 retracted, they hardly take up any space, so that the walking stick 100 is not bulky when walking, thus avoiding possible accidents.

Because the mechanics of the erection device are outside of the walking stick 100 is arranged, this is clearly visible and not hidden in a pipe, so that the operation can be learned intuitively. In addition, wear parts can easily be replaced after years of use. The exchange can be carried out by the user himself.

Although the invention has been illustrated and described in more detail by the advantageous exemplary embodiments, the invention is not restricted by the examples disclosed. Other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention. In particular, the invention is not limited to the combinations of features specified below, but other combinations and partial combinations that are obvious to a person skilled in the art can also be formed from the features disclosed.
