Description

The invention relates primarily to a holding device attach to hospital beds made from tubular frames are made, with crutches directly on the bed are held, and the crutch ends against Ver crossroads are secured, and the crutches also from Pa easily removed from the holder, but also in the holding device without any special effort tion can be reintroduced.

The convenient accommodation of crutches for patients in the hospital can be used both for the patient himself as well as for nursing staff to significant problems to lead.

Usually, crutches are placed in beds in the hospital, Tables or leaned against walls, where they are mostly fall over, can also lead to injuries, and from Patients usually with considerable effort, if at all, then reachable again.

Devices for holding crutches are in usually near the bed at tables or the like. or mounted on the wall.  

Such devices are absolutely necessary as a makeshift classify.

Such devices are either cumbersome or very cumbersome laborious.

In addition, most devices are of the type are too light and therefore unusable very quickly the.

The use of the known devices, especially in Hospitals are problematic and hardly recommendable.

The state of the art is shown in the following documents:
DE GM 82 35 229.1 (A 61H 3/02),
DE OS 33 44 372.6 (A 61H 3/02),
DE GM 83 06 493.1 (A 61H 3/02),
DE GM 88 09 357.3 (A 61H 3/02).

A satisfactory device for holding Krück Creating sticks is taking everyone into account Circumstances and demands are not an easy task, and will be unsatisfactory due to the mentioned constructions solved.

The task is complicated by the fact that once distinguished the pipe thicknesses of the crutches are, and also the crutches in principle very are bulky.

The following points and direct demands are with one usable construction of cane holders, ins especially with hospital beds, to consider:

1. The relative bulk of the crutches, due to the handles and the after back sloping forearm support Zen,

2. Different tube diameters of each a cane construction,

3. the stability of the crutch ends associated with a desired permanent Ground clearance,

4. Inclusion of canes with difference  pipe diameters in devices with a secure bracket and a safe stand the crutch stick,

5. stable and durable design the holding device and simple and quick attachment to non-obstructive place near the bed so that the patient easily accessible at any time,

6. Easy insertion and removal of the crutch sticks in or out of the holding device.

DE GM 82 35 229.1

In this construction, a go help ran out.

But if two crutches are inserted into the holding device should be brought, the opening of the ring posture be correspondingly large, and with a relatively low Ab got between the floor holder and ring holder Crutches with security in cross and are then not easy to remove.

If the distance between the base and ring holder is increased, the introduction of the crutches brings certain pros blame yourself, since the crutch ends first in the Ring holders are to be inserted. A crossing of the crutch faltering also cannot be ruled out.

Otherwise, this construction is complex and therefore expensive, also large in size and bulky. You ent speaks far from ideal.

DE OS 33 44 372 A1

In this construction, a device for holding tion of crutches proposed on the front the side of a basic element two spaced clamps mechanically firmly connected to the basic element protrude.

The construction is mainly based on wire cones structures and mounting options on tables or  similar objects using a screw clamp arena construction.

Furthermore, the construction is clearly on a particular one Crutch construction with a certain tube diameter switched off, because the crutches are clamped in shots taken in the Diameter that the crutches must exactly match, because the crutches are supposed to hang freely will.

The assumed embrace is inevitably determined by Ma material fatigue will loosen very soon and the crutches are no longer held.

This construction cannot satisfy either, as it does not solve the problems satisfactorily.

DE GM 83 06 493.1

Here is a construction of a clamp holder for stock like walking aids, such as crutches or the like. described. This construction is not suitable for hospitals absolutely, since this clamp holder is initially just a crutch can take stock. So for a pair of crutch sticks with two of these devices needed, too are attached.

With this construction, the bulkiness of the crutches not considered at all and is therefore for the sick hardly suitable for houses.

DE GM 88 09 357.3

Here is the construction of a holder for crutches described in the pipe clamps on a support plate be put on and mainly for attachment to walls or should also be suitable for furniture.

The construction is in many ways and in one points are almost identical to other constructions. So the construction also focuses on: the recesses the outer diameter of the crutches correspond. The crutches should be exempt from these be held alone.

Here too there is an inevitable rapid material fatigue  this construction for the relatively rough patient house operation can not be recommended.

The list of structures for supports of supports could continue, but for all known con Structures cannot rule out disruptive disadvantages will be.

The object of the invention was first eliminate the obvious disadvantages and the below Point 1 to 6 to take account of the above-mentioned requirements in a constructive manner and also to represent.

The task is essentially by the kenn drawing part of claim 1 solved.

The subclaims speak embodiments of the invention to. So clamp pairs are designed so that they do not hinder after attachment to the tubular part of the bed are.

Furthermore, the pairs of clamps are designed so that they accommodate differently designed supporting part units men and the crutch ends are also safe are brought.

The object of the invention is in exemplary embodiments shown in the drawing and is based on the drawings explained in more detail.

Fig. 1 shows an assembly drawing of the device Haltvorrich, which is first attached by means of the clamp pair 1 and 2 ( Fig. 1) via fastening screws 3 on the vertical pipe part 4 ( Fig. 1) of the hospital bed in the desired position.

Then a second identically designed pair of clamps 1 ', 2 ' ( Fig. 1 and Fig. 16) is attached to a suitable location of the same pipe part.

In the pair of clamps 1 and 2 ( Fig. 1 and 16), the support member unit 5 ( Fig. 1), ( Fig. 16) and ge according to Fig. 5 and Fig. 6 is then introduced.

The pairs of clamps 1 , ( 1 '), 2 , ( 2 ') ( Fig. 1 and 16) consist of two congruent clamps, each with two guide sleeves 6 , ( 6 ') ( Fig. 1, 2, 3, 4) have different lengths.

The guide sleeves 6 , ( 6 ') each have through bores 7 , ( 7 ') ( Fig. 2, 3, 4), which in turn also have Paarwei se end-sided extensions 8 ( 8 ' ) ( Fig. 2) to a to ensure better insertion of guide bolts.

To stabilize the guide sleeves, these are each provided with two pairs of ribs 9 , ( 9 ') ( Fig. 2, 3, 4).

A clamp part 2 , ( 2 ') ( Fig. 1 and 16) has a centrally located wall-thickening approach 10 ( Fig. 2, 3) in which a threaded bore 11 ( Fig. 2, 3) is attached, or a threaded bushing is pressed into which the fastening screw 12 ( Fig. 1) is screwed for fastening the supporting part unit 5 .

Both clamp parts 1 ( 1 '), 2 ( 2 ') have wall thicknesses thickening warts 13 , 13 '( Fig. 2, 3, 4), the warts 13 for supporting the screw heads 14 ( Fig. 2) with the interposition of a washer are trained accordingly, and the warts 13 '( Fig. 2) through appropriate recesses screw nuts 15 ( Fig. 4) take on rotation.

The support member unit 5 (Fig. 1 and 16) and according to FIG. 5 and FIG. 6 is composed of the base plate 16 (Fig. 1, Fig. 5 and Fig. 6 and an angularly from the base plate 16 (Fig. 1) abgabelnde Fastening rail 17 ( FIG. 1), FIGS. 5 and 6), which has stiffening ribs 18 and 19 ( FIGS. 1, 5, 6 and 16) running parallel on both sides along the longitudinal side, the stiffening ribs 18 ( FIGS. 1, 5, 6 are provided and 16) the same time as guide rails for the fixing elements to be applied later 20 (Fig. 1), according to FIG. 9-15 and FIG. 21-28.

According to the approach 10 ( Fig. 2, 3) of a clamp part 6 '( Fig. 2, 3) is on the base plate 16 ( Fig. 1, 5 and 6) a corresponding cylinder-like thickening 21 ( Fig. 5, 6) provided, but at the same time from a saving 22 ( Fig. 5, 6), in which the approach 10 prevents unintended immersion without any possibility of contact during assembly.

The cylinder-like thickening 21 ( Fig. 5, 6) is provided for fastening the screw 12 ( Fig. 1) with a through hole 23 ( Fig. 5, 6).

In addition to the stiffening ribs 18 and 19 ( FIGS. 5, 6), the angled mounting rail 17 (FIGS . 1, 5, 6) has a longitudinally extending guide slot 24 ( FIG. 6) which is limited in length on both sides.

This guide slot 24 allows a variable fastening possibility of supplying a number of fixing elements 20 ( FIG. 1 or according to FIGS. 9 to 15 and FIGS. 21 to 28).

The guide slot 24 ( Fig. 6) surrounds on one side of the mounting rail 17 a symmetrically arranged frame 25 ( Fig. 5, 6), on the inner surfaces 25 '( Fig. 6) mounting nuts 26 ' ( Fig. 1) can slide, but are secured against twisting at the same time when tightening screws.

In order to finally be able to connect the supporting part unit 5 ( FIG. 1) and according to FIGS. 5 and 6 with the clamping member lenpaar 1 , ( 2 ) ( FIG. 16) fastened to the tubular part 4 into one unit, the base plate 16 ( FIG. 1, 5, 6) with fixed angeord Neten guide pin 27 ( Fig. 1, 5, 6), which are expediently formed symmetrically and at the free ends 27 '( Fig. 5, 6) are slightly conical for easier insertion .

The guide bolts 27 can be shaped differently, but are at least in a certain length range congruent with the through bores 7 , ( 7 ') ( Fig. 2, 3, 4) of the guide sleeves 6 , ( 6 ') ( Fig. 1, 2, 3rd , 4).

The guide bolts 27 are inserted into the through holes 7 (Fig. 2) of the guide sleeves 6, the first passage holes 7 '(Fig. 2) of the guide sleeves 6' (Fig. 2) penetrating introduced.

Then the base plate 16 ( Fig. 1, 5, 6) by the fastening screw 12 ( Fig. 1) with the pair of clamps 1 , ( 2 ) ( Fig. 16) screwed into a unit.

When building a fixing element must first of all be gone that with the holding device for Krück sticks different constructions of crutches must be taken into account, especially since the pipe diameter are different.

But that requires that the fixing elements ver different pipe diameters of the crutches have to record.

It must also be borne in mind that the design the canes play a major role because of their bulkiness play.

The bulkiness arises from the cross overhangs next the handles and then backwards through the angled forearm supports.

In order to counter these circumstances, the fixing elements are structured as follows:

The fixing element consists first of the base 28 ( Fig. 9) and the cohesive free-ended leg pair, the immediately opposite Be tenflächen 29 '( Fig. 9) parallel to a certain length.

The inside width B ( Fig. 9) is a few tenths of a mm wider than the largest pipe diameter of commercially available crutches (usually max. 22 mm ⌀).

The construction according to the invention is based on the idea reasons not to hold on to the crutches ten.

One reason is to make the length L ( Fig. 9) at least 2½ times longer than the width B.

Only this characteristic design feature makes it possible light an intended inclination of the crutches, the because of the protruding design of the forearm supports the crutches may be required.

The indentation 33 ( FIG. 9), which should be a maximum of 18 mm inside, prevents the crutches from slipping out, even those with weaker tube diameters. The spring action of the free legs is in addition to the ge suitable material and the thickness of the legs in particular rem favored by the obvious leg length.

When the crutch is inserted into the fixing element, the indentation 33 springs open, and after the crutch is introduced, the pair of legs returns to its starting position.

The introduction of the crutch is made easier by the bulge 34 .

The guide slot 24 ( FIG. 6) does not bind to a fixed positioning of the fixing elements on the fastening rail.

For the lateral guidance of the fixing elements, the base 28 ( FIGS. 9-11) has parallel surfaces 29 . These surfaces 29 slide on the guide surfaces 18 '( Fig. 6) of the reinforcing ribs 18 ( Fig. 6).

Under certain circumstances, however, there may be a need for the fixing elements, pivoted in their longitudinal axis LA , to be fastened on the fastening rail 17 . For this purpose, the base 28 has additional bases 30 and 31 ( FIGS. 12 to 14), which on the one hand permit a limited and on the other hand an unlimited pivoting.

The additional bases can be combined with the basic base form, but expediently the additional base as loose discs with a central through hole fitted.

The tightened fastening screw 26 ( FIG. 1) then forms the base and the respective additional base as one unit.

Another embodiment of the construction according to the invention is shown in FIGS. 21 to 28.

According to the invention, it is known that there is an immediate Clasping the cane tubes by the holding device tion waived.

But for special cases and on request on wobble-free Not to have to do without the crutches, the fixing element is designed in two parts.

The free legs 32 each have individual pieces branching angle pieces 42 and 42 '( Fig. 23 to 26), the bottom surface 47 , measured on the legs, has the same base.

The Teilfixierelement to FIGS. 23 and 24 has a ver reinforced branching off angle piece 42, because it has parallel ver running grooves 45 in the congruent, but longitudinally displaceable, ribs 46 of the elbow 42 '(Fig. 25 and 26) engage.

The Teilfixierelement to FIGS. 25 and 26 has a congruently running with the through-bore 43 longitudinal slot 43 '.

The angle pieces 42 and 42 'are matched to one another so that they grip the same aligned bottom surface 47 after a grip the ribs 46 in the grooves 45 with the bottom or surface of the elbows.

The inner width B '( Fig. 22) can be made variable by the slot arrangement 43 ' ( Fig. 25).

The insert of a circular disc according to FIGS. 27 and 28 between the surface 47 of the angle piece 42 and the sliding surface of the fastening rail 17 then also enables pivoting of the assembled partial fixing element, which forms a unit through the fastening screw 26 ( FIG. 1).

Instead of the circular disc, another can also be used designed intermediate piece find use.

In the second identically designed also on the vertical pipe part 4 ( Fig. 16) attached clamp pair 1 ', ( 2 ') ( Fig. 16), the shell-shaped section according to Fig. 17 to 20 in the same way as the support unit 5 ( introduced FIG. 1, 16) and according to Fig. 5 and 6 and fastened.

This is made possible by the fact that the base plate 16 and the base plate 36 ( FIGS. 17 to 20) are completely identical.

In the shell-shaped portion of Fig. 17 to 20 and 37 (Fig. 1 and 16), the Krückstockenden 38 (Fig. 1 and Fig. 16) is set. This prevents the crutches from crossing.

The rear side of the bowl is expediently shaped gene portion increased trained.

With appropriate attachment of the pair of clamping shells 1 ', ( 2 ') on the pipe part 4 , a permanent ground clearance 39 ( Fig. 16) is also achieved.

The crutches are safely stored and can be from Patients easily removed and reinserted.

Another desired positioning of the crutches 35 can be achieved in that the clamps pair 1 ', ( 2 ') ( Fig. 16) is rotated about the vertical axis, and thereby the transverse axis 40 ( Fig. 1) changes.

By another arrangement of the shell-shaped part 37 ( Fig. 1), the transverse axis 40 ( Fig. 1) can also be moved parallel to both sides or fundamentally changed the transverse axis.

So that there is the possibility that after final assembly of the clamp pairs these may be tightened or loosened again without great effort on the screws 3 , the base plates 16 and 36 have through-holes 41 (FIGS . 5, 7, 8, 17, 18, 20) on, which allow easy passage of screwdrivers.
