Description

The invention relates to a mobile crutch stand module with continuously adjustable properties, preferably for use in pairs, according to the preamble of claim 1.

There are a large number of inventions which deal with the solution of the problem of free storage of crutches or walking aids by means of a sensible standing device, but these proposed solutions mainly aim at an individual solution, i.e. to create its own standing device for each crutch.

These single crutches then have to be upgraded with a relatively high technical and financial effort, since they need at least 3 support points for a safe stand, ie. that at least two additional support bodies per crutch are required, for example
CH 688 175 A5 ; EP 0 958 803 A2

If only one crutch is used, e.g. in the case of a less severe disability, this solution may be justifiable, but it is often necessary to intervene in the crutch substance of these orthopedic devices, which can lead to problems in the event of accidents and make the walking aid disproportionately expensive and expensive make it difficult (weight).

There are also known individual crutches which are continuously adjustable in length, for example
CH636 005 A5 ; DE 4137 466 A1 ; DE 1276 293
In all 3 cases, however, these are not crutches or walking aids with the right to a freely adjustable device in the sense of the task to be solved. They only serve as a stand-up aid or to fix the height of the crutches. The energy storage device proposed for this in the form of hydraulic systems or electric motors etc. would no longer be conceivable at the present time and for these applications mentioned here for a variety of reasons. Commercially available crutches or crutches with an average dead weight of 600-650 grams consist only of an upper part with handle and shell, 2 telescopically connected light metal tubes with safety clip and crimp connection, and a foot capsule. They must be easy to use, light in weight and, of course, inexpensive to obtain. Since they are usually arranged by the orthopedic surgeon and paid for by the health insurance company, special requests such as stand devices that go beyond a standard crutch variant must be paid for by the user himself.
This is also one of the reasons why you see so few or no copies of so many well-intentioned but sometimes highly upgraded crutch systems in daily life.

Now, in practice, mostly “pairs of crutches” are used! In order to make it more difficult or even to prevent the two crutches of a pair of crutches from falling over when they are parked, aids are suggested that may alleviate the problem somewhat, but cannot solve it, for example
EP 3 473 229 A1 ; DE 200 13 369 Ul; DE 200 18 143 ;
DE 201 14 228 U1

For this reason, a pair of crutches can only be parked freely if at least one of the two crutches is equipped with a support body and additionally both crutches are equipped with a simple and uncomplicated connection mechanism, the latter requirement definitely missing from the following contributions, for example
EP 1 723 942 A1 ; DE 101 28 382 A1 ; DE 20 2008 016 033 U1 ;
DE 20 2007 014 880 U1 ; DE 10 2009 017 291 A1 ;

The examples show that the support bodies, some of which are oversized in most cases, are present, but the connection system between the two crutches of a pair of crutches has so far been unsatisfactory for the user. A simple and quick changeover, for example from the action position (crutch is actively used) to the park position (crutch is turned off) and vice versa, will not be possible because of the patient's several technical requirements. Kind are to be considered.
Since crutches are also utensils that are very close to the body, magnetic connecting elements, which are often suggested, are unsuitable for patients with cardiac pacemakers, for example.

The invention specified in claim 1 is based on the object of creating a flexible device with which essential disadvantages of the type mentioned at the outset can be eliminated and which include the following features:

• - Unique selling points, including with regard to a stabilizing crutch connection with no additional external connecting elements of any kind, simply by placing the crutch handles loosely on top of one another or armrest on the handle.
• - Modular design with optionally different possible energy stores such as pneumatically acting gas pressure springs, mechanically acting compression or tension springs.
• - Modular construction with a choice of different possible tube-clamp systems such as one-piece - symmetrically contoured clamps or two-part eccentric contoured clamps.
• - Inexpensive production, including through modular construction and partial use of inexpensive / commercially available components.
• - easy to use, suitable for right and left handers alike.
• - continuously adjustable properties.
• - Extended length-adjustable properties through "length presetting".
• - Mobile use, compatible with almost all known commercially available crutches.
• - extremely low crutch weight gain of a crutch modified with the crutch stand module; only in the 100-150 gram range (adjusted), depending on the type of lift mechanism used.

The object is achieved according to claim 1 in that a modular device is made available in the form of a crutch stand module which contains all the requirements for solving the tasks set.

1. 1. Modul-Oberteil
2. 2. Modul-Unterteil

According to the invention, the crutch stand module is composed of two mutually compatible interlocking sub-devices:

1. 1. Module upper part
2. 2. Lower module part

1. 1. Einteiliger Klemmer mit symmetrischer Kontur
2. 2. Zweiteiliger Klemmer mit exzentrischer Kontur

Beide Klemmer-Systeme bestehen einerseits aus einem Rohr-Klemmverbinder-Gehäuse mit Andockmöglichkeit einer handelsüblichen Krücke (Hauptrohr) und andererseits aus einem ein- oder zweiteiligen Klemmer, verbunden mit Hebel und Stützkörper, dessen besondere Eigenschaften darin bestehen, dass der Stützkörper Schalt- u. Stützfunktion gleichzeitig ausübt und im verbauten Zustand vertikalschwenkbare Eigenschaften, ähnlich eines Fahrradständers besitzt.The module upper part is primarily a universal pipe clamp connector system made of injection-moldable plastic, which is composed of several upper part components, for which in particular 2 possible alternative clamp connector systems are relevant,

1. 1. One-piece clamp with symmetrical contour
2. 2. Two-part clamp with eccentric contour

Both Klemmer systems consist on the one hand of a pipe clamp connector housing with docking option of a commercially available crutch (main pipe) and on the other hand of a one or two-part Klemmer, connected with lever and support body, whose special properties are that the support body switching u. Simultaneously exercises support function and, when installed, has vertically swiveling properties, similar to a bicycle stand.

The module lower part is also composed of several lower part components, among which there is also an energy storage device and another connection option for connecting to the main pipe of a commercially available crutch.

1. 1. Pneumatisch-wirkender Kraftspeicher (Gasdruckfeder)
2. 2. Mechanisch-wirkender Kraftspeicher (Druckfeder)
3. 3. Mechanisch-wirkender Kraftspeicher (Zugfeder)

Alle 3 Kraftspeicher-Typen besitzen die Möglichkeit, in einem vorwiegend aus Leichtmetall bestehenden Rundrohr so verbaut werden zu können, das sie in Verbindung mit weiteren Unterteil-Komponenten ihre Aufgabe für eine stufenlose höhenverstellbare Funktion der Krücke wahrnehmen können.For the lift mechanism components that can be used to solve the problem, 3 alternative lift mechanisms are relevant:

1. 1. Pneumatically acting energy storage device (gas pressure spring)
2. 2. Mechanically acting energy accumulator (compression spring)
3. 3. Mechanically acting energy store (tension spring)

All 3 lift mechanism types have the option of being installed in a round tube predominantly made of light metal in such a way that they can perform their task of continuously height-adjustable function of the crutch in conjunction with other lower part components.

Both partial devices (module upper part and module lower part) combined result in the crutch stand module according to the invention.
The upper module part can be moved telescopically over the round tube of the lower module part (up and down) and, depending on the desired length position, locked with the one-piece or two-part clamp on the round tube, with the automatic clamping mechanism being carried out by the support body connected to the clamp, which performs both switching and support functions at the same time for this measure.

The crutch stand module roughly cited in this way can be connected to almost all known, commercially available crutches without any problems and without specialist knowledge with regard to high mobility requirements.
This is done on the one hand by a simple "push button system" on the side of the lower module part and on the other hand by means of a clamping device of the pipe clamp connector system from the upper module part.

1. 1. sie dient z.B. bei Besitzerwechsel oder Krücken-Längen-Nachjuszierung dem Zwecke einer schnellen- u. einfachen Anpassung der Krückenlänge
2. 2. sie ermöglicht dem Patienten eine bessere Alltags-Mobilität, da er zu jeder Zeit und augenblicklich sein Krückenpaar nahezu ortsungebunden, frei und ohne weitere Hilfestellungen abstellen kann.

In terms of construction, it was taken into account that the crutch stand module, in addition to its actual supporting function, is to be equipped with a continuously variable length thanks to the Klemmer support body. This beneficial property has two advantages:

1. 1. It is used, for example, when changing hands or adjusting the length of the crutches for the purpose of quick and easy adjustment of the length of the crutches
2. 2. It enables the patient to have better everyday mobility, since he can park his pair of crutches at any time and instantly, almost anywhere, freely and without further assistance.

These positive properties could be included in the development by means of the different energy stores, in combination with the universal pipe clamp connector system placed in the module upper part, can be implemented in a satisfactory manner.
It is worth mentioning that the infinitely variable length adjustment could be expanded to include a "length presetting" with a particularly attractive option, the advantages of which will also be referred to again in the following.

A further, particularly advantageous embodiment of the invention is claimed as a current unique selling point.
Accordingly, a commercially available crutch can be connected together with a crutch modified with the crutch stand module as a pair of crutches, with the support body extended, simply by laying the two crutch handles loosely on top of each other, without additional aids, so that the pair of crutches can be independently connected without falling over, remains free in the area and thus fully fulfills the task according to claim 1.

This makes the handling of the crutches much easier for the patient, the costs are reduced and the weight of the crutches is minimized insofar as the sometimes considerable technical and weighty effort for connecting elements often considered to hold two crutches together is eliminated, even without more or less major interventions in the having to make the crutch substance.

In the following, exemplary embodiments are to be further explained with the aid of figures, partly in schematically illustrated sectional views and schematic diagrams (not true to scale).

Summary

1. 1. der anfangs hochliegende Krücken-Schwerpunkt verringert sich durch den Absenkvorgang der Krücke statisch derart, dass sich dies positiv zugunsten der gewünschten Standsicherheit der Krücke gegen umkippen auswirkt.
2. 2. Eine „lose und doch stabilisierende Verbindung“ der beiden nun unterschiedlich langen Krücken ist gem. 20, lediglich durch übereinanderlegen von Armschale / Handgriff oder gem. 21, Handgriff / Handgriff möglich.
3. 3. der Stützkörper selbst kann infolge seiner nun bodennahen Position konstruktionsmäßig sehr kurz gehalten werden, sodass er mit einer Baulänge incl. Hebel, von ca.150mm auskommt um in Verbindung mit den Ausführungen 1,2, die Standfestigkeit des Krückenpaares gegen umfallen sicherzustellen.

Foreword: The legitimate wish of every patient is to be able to quickly switch from the action position (A) to the park position (C) and back with his pair of crutches. According to the invention, this is done in a certain way according to the scheme of the bicycle stand principle, by folding out the clamping lever or its support body from the action position (A), preferably with the foot, and by simultaneously pressing the crutch handle ( d ), the crutch can instantly be lowered continuously by at least 200mm, whereby the lower end of the pipe-clamp-connector-housing ( 2.3 ) then only acc. 1 on near
Stop upper edge of foot capsule ( 1.6 ) is located at one
Capsule about 50-60 mm to the ground and corresponds roughly to the height of a standard foot capsule.
With this process and as a result of the crutch length, which is now considerably shorter than the total length, several advantages are achieved at the same time, including:

1. 1. The initially high crutch center of gravity is statically reduced by the lowering process of the crutch in such a way that this has a positive effect in favor of the desired stability of the crutch against tipping over.
2. 2. A "loose and yet stabilizing connection" of the two crutches of different lengths is in accordance with 20th , simply by placing the armrest / handle on top of each other or in accordance with 21 , Handle / handle possible.
3. 3. Due to its position close to the ground, the support body itself can be kept very short in terms of construction, so that it manages with an overall length including lever of around 150mm in order to ensure the stability of the pair of crutches against falling over in connection with versions 1, 2.

Now the patient only needs to position the two crutches of the pair of crutches accordingly in order to use the simplified connection technology - see unique selling point - to park the pair of crutches freely in the park position (C) without additional aids.

Conversely, the patient can quickly return to the action position (A) with his two crutches by picking up the two crutch handles and the clamping lever with support function of the modified crutch with the aid of his foot or hand via the release position (B) the selected energy storage device relaxed in order to automatically return to the starting or action position (A).

Move up (= final tension) or down (= tension).
The required push button tension is achieved by means of a
Expanding spring ( 1.7.3 ) achieved, which the two push buttons on the inner wall or through holes of the round pipe socket ( 1.7 ) fixed.
Via the clamping device ( 2.3.1 ) of the pipe clamp connector housing ( 2.3 ) is now also that of the armrest ( c ) or handle ( d ) the slimmed-down commercial crutch coming end of the main pipe ( a ) with the pipe clamp connector system from the module upper part 2.0 with the upper part components ( 2.1 - 2.6.1 connected, so that with more or less pressure on the crutch handle ( d ) via main pipe ( a ) both in the lower part of the module 1.0 the lift mechanism located there as well as the pipe clamp connector system of the module upper part 2.0 move synchronously with each other.
With this connection system, the main pipe ( a ) the module upper part 2.0 with the connector housing ( 2.3 ) telescopic over a round tube ( 1.4 ) (up or down) by moving the gas spring cylinder ( 1.1 ) telescopic in a round tube ( 1.4 ) is moved and thus tensioned or relaxed according to its position.
The clasping of the round tube ( 1.4 ) through the pipe clamp connector system of the module upper part 2.0 is influenced by means of the one-part or optionally the two-part clamp in the manner that according to. 15th ; 16 ; 17th whose surface structures are shaped and designed in such a way that, depending on their positioning, the locking or release of the round tube ( 1.4 ) happens in such a way that the system is blocked in the action position (A), the blockage is released in the release position (B) and the blockage is reactivated in the park position (C).

10 , shows using a basic scheme how a crutch length can be preset.
With this pre-setting, for example, if there is a change of owner, only a one-time basic setting is required, as this automatically adjusts itself to the set height again after the position actions have been carried out.
In , , an example is used to show how the
"Crutch length presetting" - in this application case with the mechanically acting compression spring version ( 1.2 ) is carried out by shortening or lengthening the threaded rod ( 1.5 ) by screwing it more or less deeply into the pipe end plug ( 1.7.1 ) the round pipe socket ( 1.7 ) the presetting is possible.
, shows the crutch height H1 with a preset distance of the threaded rod between the spring tensioning bolt ( 1.2.1 ) and pipe stopper ( 1.7.1 ).
, indicates that the crutch height H2 is shortened by the same length,
like screwing in the threaded rod ( 1.5 ) in the end plug ( 1.7.1 ) the round pipe socket ( 1.7 ) was created.

11 , shows again a longitudinal section of an embodiment of the device according to the invention of a mechanically acting compression spring version 1.2 in park position (C) with integration of a two-part eccentric contoured clamp ( 2.2 ) and various position information in relation to the pipe clamp connector system of the module upper part 2.0 .
The modified crutch stand module will not stand in an upright position on the floor shown. In the "vertical" position, free standing is only possible to a limited extent, because there is a risk due to the unfavorable weight distribution (statics) by later putting on arm rests ( c ) and handle ( d ) to tip forward.
In addition, in this case the support body ( 2.4.1 ) can be lengthened considerably in order to be able to establish optimal ground contact. Only by tilting the crutch slightly "back" about 10 ° towards the patient can there be sufficient ground contact so that the support body can fulfill its function as a support leg in accordance with park position C.
The extended total length of the support body is approximately 130-150mm.
The possible functional angular degrees of the support body can be continuously adjusted between the respective positions of action, release and park positions and can be numbered at around 60 ° -70 ° each.
However, this information is only intended as a guide and is not representative, as it depends on various factors such as the type of crutch, etc. The location, for example with or without a slope, also plays a role in the extent to which the patient has to extend his support body in order to secure a stable stand against falling over. In practice, however, the patient will immediately noticeably recognize when the support body is in the correct position ( 2.4.1 ) is achieved so that the pair of crutches can stand independently.

In 13th is shown schematically how the patient can steplessly adjust his crutch length H1, for example in a pneumatically operated gas pressure spring variant (also applies to the mechanically operated energy storage device).
To do this, he will use the Klemmer support body ( 2.4.1 )
according to , from the action position (A) to the release position (B),

according to , and at the same time by applying pressure to his crutch - if he is, his
Would like to reduce crutch height - readjust his height H2
according to , in order to then use the newly deviated crutch length H2 again with the
Klemmer support body ( 2.4.1 ) in the action position (A).

14th shows how easy it is to integrate the mobile crutch stand module into a standard crutch. It does not matter whether the module is a pneumatically operated gas pressure spring version or a mechanically operated compression or tension spring version. , , the lower part pipe ( G ) with foot capsule ( H ) by pulling out the fastening clip ( e ) from the diametrical hole ( b ) from the main pipe ( a )
a commercially available crutch is removed, as well as the clamp connector ( f ) as well, so that in the end only a slimmed down version of the commercially available crutch is available for further connection with the crutch stand module according to the invention.
In , , the module equipped with the pneumatically-acting gas pressure spring or mechanically-acting compression or tension spring is then connected to the in shown main pipe ( a ) connected to the commercially available crutch by pulling the main pipe using the clamping device ( 2.3.1 ) on the pipe clamp connector housing ( 2.3 ) of the pipe clamp connector system from the module upper part 2.0 is attached and the second connection of the main pipe ( a ) via the push button system ( 1.7.2 ) takes place.

In 15th , is a schematic sectional view of the simplest version of the universal pipe clamp connector system from the module upper part 2.0 shown, whereby the clamping effect of a one-piece, symmetrically contoured clamp (3.1) on the round tube ( 1.4 ) can be transferred directly.

Klemmer ( 2.2 ) on the round tube ( 1.4 ) can be transmitted indirectly by placing a clamping pad ( 2.5 ) as well as a clamping sleeve ( 2.6 ), whereby the clamping pad is positively locked between the clamp ( 2.2 ) and the clamping sleeve ( 2.6 ) is adapted and the inner wall of the clamping sleeve the round tube ( 1.4 ) directly encloses and thus exerts the effect of a "brake disc" with direct braking or clamping action on the round tube.
With this arrangement, the braking or clamping performance is optimized and the load-bearing capacity of the crutch can be increased again.

18th , shows the same arrangement of the braking or clamping means as in 17th , only in a different representation, including a view of the clamping sleeve incision ( 2.6.1 ). This incision between the clamping pad ( 2.5 )
and round tube ( 1.4 ) is of great importance for the optimal transmission of braking or clamping force, as the clamping sleeve in the slotted environment better yields the axial pressure emanating from the clamping pad or clamp and thus the braking or clamping effect on the round tube due to an enlarged friction surface ( 1.4 ) will strengthen.

In 19th , a modified crutch in the park position (C) according to claim 1 with alignment of the crutch handle ( d ) in the walking direction (front) and the opposite one

It shows a parked, free-standing pair of crutches, whereby the standard crutch is laterally aligned towards the modified crutch with an angle of attack adapted to the environment, and its armrest (c ') on the handle ( d ) the modified crutch with a stabilizing effect is loosely applied. The modified crutch equipped with the crutch stand module according to the invention is almost vertical, with a slight inclination (<10 °) towards the patient. The support body ( 2.4.1 ) is opposite to the forward-facing handle ( d ) positioned. With the crutch extended to the maximum length, the lowering process required for the parking position can lower the crutch by at least 200 mm, so that a not inconsiderable difference in length can arise between the commercially available and modified crutch. The modified crutch inevitably has the shortest length, which for static reasons has a favorable effect on the stability of the two crutches.

In 21 is the difference to that in 20th The self-standing pair of crutches shown only in that the stabilizing connection between the two crutches is not created by loosely placing the armrest (c ') of the standard crutch on the handle ( d ) of the modified crutch takes place, but by loosely placing the handle (d ') of the standard crutch on the handle ( d ) the modified crutch can be brought about. In practice, however, the patient will decide for himself which type of connection between his two crutches he would prefer to use. Among other things, the terrain in which he would like to park his pair of crutches will also play a role. 20th Select.
