DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a telescopic combination device for crutches and walking sticks.

BACKGROUND OF THE INVENTION Crutches or walking canes, which are well known to those skilled in the art and generally available almost everywhere, consist of a metal tube with one or more telescopic sections that are adjustable in length to fit people of different heights. This includes: For example, C0NCE
NTRICMAN[IFACTUR[NG COMPA
NY LTD, UK Patent No. 685.781 and GISH No. 2,383.786, PBTER3 No. 2.575.681, GRIMBAL No. 2.59
No. 0.607, No. 2.630.128 of 5LATER and No. 2.817.34 of HOLLIDAY, Jr.
Reference may be made to US patents such as No. 8.

It can be easily folded and deflated so that it can be conveniently stowed away in a suitcase when not in use.
Crutches are known which consist of a sufficient number of telescoping tubes that can be extended into an operative position in a very simple manner during use. for example,
The crutch described in Kelly British Patent No. 122,694 consists of several lengths of tubes that fit telescopically into each other.

Furthermore, devices are known that can be used as conventional walking sticks and can be easily converted into crutches. Thus,
For example, SM (TH, Jr., U.S. Patent No. 2゜960)
, No. 095, the combined crutch and walking cane device [allows the components forming the crutch to be folded up virtually imperceptibly when the device is used as a cane”. Since the part made of metal tube is expandable and retractable, it can be converted into either a walking stick or a crutch, and its length can also be adjusted.

PROBLEMS SOLVED BY THE INVENTION The first object of the present invention is to quickly and easily convert from one use to another, such as the apparatus described in U.S. Pat. No. 2,960,095. It is not only convertible into a bag, but also quickly and completely foldable so that it can be plugged in as part of a piece of luggage, such as a simple case, yet adjustable to fit an average user of any height. An object of the present invention is to provide a combination device of a crutch and a walking cane that can be extended.

Another object of the invention is to mount a telescopingly adjustable full length tube in a non-rotatable sliding manner within another tube;
Said type in which all but one of the plurality of selectable positions of each adjustable length are occluded by the user after appropriate adjustment according to the user's physical needs. The goal is to provide the following products. With such characteristics,
This feature is extremely important because the combined crutch and walking cane device according to the invention performs properly and excessive tube adjustments are avoided. If the selectable position consists of a plurality of alignment holes in the tube, the telescoping tube may be provided with mutually opposing flats to prevent relative rotation between the tubes, thus preventing the tube from becoming loose. This feature can be effectively achieved by eliminating alignment and by providing a closure device, such as a resilient ring or strip, which can be attached to the tube wall to occlude all but one of the alignment holes in each tube. The provision of such a provision gives the device a kind of "memory", allowing it to always be extended or contracted to a predetermined length without the need for actual adjustment.

A further object of the invention is to provide a shock absorbing sleeve, preferably made of rubber, in each of the armpits and the crutch so that the crutch/walking cane combination can be hung from a shelf or the handles can be placed on the flat surface of a table. It is a further object of the invention to provide a device of the above type in which the sleeve is tapered on the outside so that it is suitable for placing and hanging on the table. The object of the present invention is to provide a device of the above type which has an extremely simple structure.

Means for Solving the Problems The telescopic combination crutch and walking cane device according to the present invention comprises a lower ground pipe, a central pipe slidably attached to the ground pipe, and several parts of the lower pipe. a first locking device on the central tube for positioning the central tube in a selectable position; an upper tube slidably attached to the central tube and having an upper free end; and several of the central tubes. a second locking device provided on the upper tube for positioning the upper tube in a selectable position; an underarm support attached to the upper end of the upper tube; and a walking cane attached to the upper end of the central tube. and handles.

The lengths of the lower, middle and upper tubes are determined such that the length when fully retracted when fitted together is approximately 173 mm of the fully extended length of the combined crutch and cane device. Ru.

Spaced alignment holes are formed in the walls of the central tube and the lower tube, respectively.

The first locking device mounted within the central tube for positioning the central tube within the lower tube includes a first detent knob extending internally and laterally at the lower end of the central tube, and a first locking device mounted within the central tube to position the central tube within the lower tube. and a spring device for resiliently pressing the first knob into one of the alignment holes. The second locking device, also mounted on the upper tube for positioning the upper tube within the central tube, includes a second detent knob extending laterally inwardly at the lower end of the upper tube, and a spring device for resiliently urging the second knob into one of the alignment holes of the tube.

According to a first feature of the invention, the crutch and walking cane combination device further comprises a device for preventing relative rotation of the lower, middle and upper tubes, and one of the alignment holes in the lower and middle tubes. It further includes a device for closing all holes other than the

Preferably, the anti-rotation device is provided in the lower, middle and upper tubes and comprises flat portions facing each other. In this case, the alignment holes of the lower and central tubes are formed through the flattened portions of the lower and central tubes, respectively.

Each of the alignment holes of the lower and central tubes is formed with a respective groove along at least a portion of their walls, and the closure device is configured to form grooves in each of the alignment holes of the lower and central tubes for sealing the introduction of the detent knob. All of the large grooves include elastic rings that are removably introduced.

A linear sliding groove is formed in the inner longitudinal direction of the flat portion of the central and lower tubes, the sliding groove is adjacent to the alignment hole of the central and lower tube, and the closure device is configured to include a flat portion that slides into the groove. a strip having essentially the same length as the central and inferior tubes, respectively, and adapted to accommodate the extubation when mutually adjusting extubation by alignment with preselected holes in the corresponding central or inferior tubes; Each is provided with a single hole positioned to allow movement of the corresponding detent knob only into the preselected hole.

According to another feature of the invention, the crutch and walking cane combination device according to the invention is provided such that the alignment holes in the central tube are evenly spaced from each other and the alignment holes in the lower tube are spaced uniformly from each other. The center and lower tubes are uniformly spaced apart from each other, with the alignment holes in one of the central and lower tubes having a spacing between them that exceeds the spacing between the alignment holes in the other tube. Due to this feature, the overall length of the combination device can be suitably selected.

According to a further feature of the invention, the axillary support includes a T-shaped member having a lateral axillary platform, a pair of free ends extending vertically into the axillary platform and extending vertically into the upper tube. It includes a central cavity sized to fit the upper end and a device for removably securing the underarm platform to the upper end of the upper tube when the upper end is fitted into the cavity.

A pair of buffer sleeves of flexible material are forced over the T-shaped member from their free ends toward the central cavity. Each of the sleeves, which acts as a buffer,
It has a cross section that increases uniformly in dimension from the central cavity towards the free end of the T-shaped member.

Similarly or alternatively, a similar cushioning sleeve may be force-fitted onto the handle to facilitate gripping the walking cane as well as hanging it from a table.

In order to make the combined crutch and walking cane device according to the invention extremely easy to assemble, it is preferable to mount the first locking device in a small longitudinal hole in a first plug made of plastic material and fixed to the lower end of the central tube. Similarly,
Preferably, the second locking device is provided in a small vertical hole in the second plug, which is made of plastic and is secured to the lower end of the upper tube.

In this case, each of the first and second plugs is provided with an outwardly projecting skirt for slidably guiding the lower ends of the central and upper tubes centrally within the lower and central tubes.

DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will be described in detail below with reference to the accompanying drawings, which illustrate embodiments of the invention.

As shown in the accompanying drawings, the telescoping collapsible crutch and walking cane or cane combination device according to the invention comprises a lower grounding tube 1 and a central tube 3 telescopically slidable within the lower tube 1. and an upper tube 5 telescopically and slidably received within the central tube 3 and having an underarm support 7 at its upper free end.

A walking cane handle 9 is provided at the upper end of the central tube 3.

Furthermore, the lower end of the lower tube 1 is provided with a grounding rubber pad or foot 11 which is removably attached to the distal end of the lower tube 1.

In particular, as is clear from Figures 1 and 2, tube 1.3
The lengths of and 5 are determined so that the total length of the combined crutch and walking cane device when the limbs are housed together as shown in FIG. 2 is 173, which is the length when fully extended.

In other words, the lengths of tubes 1, 3 and 5 are approximately the same.

The central tube 3 and the lower tube 1 each have a series of holes 13.15.
in which case the fluid hole extends through the wall of the limb canal,
It rises to the entire length and is spaced apart.

As shown in FIG. 4, a first fixing device is provided at the bottom of the central tube for positioning the central tube 3 in one of a series of selectable positions on the lower tube 1. As shown in FIG. Such a first fixing device includes a first plug 14 made of plastics material, one end of which is force-fitted into the tube 3 and the other end facing an alignment hole 15 of the first tube. A horizontal hole 16 for orientation is provided. A first detent knob 17 is slidably mounted inside the hole 16. The shoulder 19 of the knob is larger than the hole 15 so that it cannot escape from the central tube 3. The spring 21 elastically presses the knob 17 against the hole 150 and holds the knob 17 in this position by the engagement of the shoulder 19 with the inner wall of the central tube 3.

It can be seen that the length of the knob 17 is sufficient for the knob to fit into either of the lower tube holes 150 when one of the lower tube holes 150 is aligned with the knob. It can thus be seen that by pushing the knob 17 inwards and out of one of the holes 15, the central tube 3 can be slid relative to the lower tube I until the other hole is reached.

A device is thus provided for releasably locking the two tubes 1 and 3 in order to achieve the desired overall length.

As shown in FIG. 6, a second locking device similar to the first locking device is provided at the lower end of the upper tube 5 in a second plug 14' similar to the first plug.

The detent knob 17' of the locking device is engageable with any of the holes 13 provided in the central tube 3.

Therefore, the overall length of the tubes 3 and 5 can be adjusted as required, the number of selections being the same as the number of holes 13.

Since such a second locking device is identical to the first locking device, elements of the same structure are provided with the same reference numerals but primed for distinction.

The holes in the central and lower tubes 3 and 1 can be evenly spaced from each other. However, as shown in FIG. 1b, in order to better select the length of the assembly, it is preferred that the holes in one tube be spaced more widely apart than the holes in the other tube.

so that the lines of holes 13 and 15 always overlap constantly,
Each telescoping tube 1, 3 and 5 must not rotate relative to each other to facilitate alignment of the holes and insertion of the detent knobs 17 and 17' of the tubes 3 and 5 therein. The anti-rotation device usable with the invention is clearly illustrated in FIG. 8, where the telescoping tubes 1 and 3 are shown in cross section rather than in longitudinal section as in FIG. Tubes 1 and 3 as shown
Since the flat portions 1' and 3' are provided facing each other, relative rotation can be eliminated. Similarly, the upper tube 5 is also provided with a flat portion, although not shown. The holes 13 and 15 extend centrally through the flat parts 1' and 3'.

Figures 7.8 and 10 show a reliable method for achieving the desired mutual lengths of tubes 1 and 3.

This method introduces a detent knob 17° 17' in only one of the holes 13 or 15 in each of tubes 3 and 1 in order to bring the relationship of tubes 1, 3 and 5 to a suitably preselected length. In this way, the other unselected holes 13 or 15 are closed to prevent the detent knobs 17 and 17' from entering.

The hole closing device is for telescopic tubes 1 and 3 and is detailed in FIGS. 8 and 10. It can be seen that similar principles apply to tubes 3 and 5.

7, 8 and 10, each of the holes 15 is partially formed with an arcuate groove 18 extending around the hole 15 (the first
(See figure 0). The periphery of the resilient ring 20 or circular clip 200 received within the groove 18 is bent inward to form a U-shaped stop 22 to occlude most of the central portion of the ring 20. The ring is inserted into the hole 15 using the U-shaped stopper 2.
2 arms and guide them toward each other, groove 18
This can be done by reducing the diameter of the ring 20 once it is in place over a period of time. Releasing the arm of the stop 22 causes the ring to expand and fit into the groove 18. As shown in FIG. 10, groove 18 does not extend around the entire periphery of hole 15. As shown in FIG. The ungrooved area around the area is hole 1.
5 and provides a wider bearing surface for the knob 17 so that the knob does not wear out.

As can be seen in Figure 10, the stop 22 extends across the hole 15 after insertion of the ring and prevents the knob 17 from entering the hole.

FIG. 11 shows another type of closure device. In this case, the hole 15 opens on the inside of a sliding groove that is formed over the entire longitudinal length of the flat part or land 1' of the tube 1 and is limited on the inside by a pair of opposing shoulders 26 and 26'. . The straight groove 24 thus adjoins the bore 15 of the tube 1. A flat strip 28, essentially the same length as the tube 1, slides into the inner groove 24;
It is stopped at the bottom by the top surface of the foot pad 11 (FIG. 3).

In the case of the tube 3, the corresponding strip can be stopped below by the top surface of the plug 14. Alternatively, such a stop may be effected by stamping or punching out the walls of tubes 1 and/or 3 at appropriate locations to provide small internal protrusions 54 (FIG. 11). A similar projection may be provided at the top of the canister to prevent the inserted strip 28 from rising when the crutch is extended. protrusion 54 when changing or having to readjust the strip;
A transverse hole (not shown) may be provided in the tubes 1 and 3 near the top of the strip to allow the insertion of a pin used to remove the strip from the groove 24 provided over it.

As a matter of course, it can be seen that the structure of the extraction groove 24 and the strip 28 also applies to the tube 3.

The strip 28, which may be constructed of plastic material, includes a series of transverse score lines spaced longitudinally such that the hole in the strip is aligned with a predetermined hole 15 and can be cut to a predetermined length. (not shown) and a single hole. Groove 2
By adjusting the length and position of the strip 28 within 4, the punched hole allows the detent knob 17 to be introduced only into the preselected hole 15. Therefore, detent knob 1
7 moves only into the hole 15 thus released. In this case as well, the same construction as described above for tube 3 applies with respect to the detent knob 17' of tube 5.

As mentioned above, at the upper end of the upper tube 5, as shown in FIG.
An underarm support 7 is provided which includes a T-shaped member having a pair of free ends 41,41'. The central portion of the member 39 is provided with a downwardly opening cavity 43 extending perpendicularly thereto. The dimensions and shape of the cavity 43 are such that it accommodates a plug 45 held at the upper end of the upper tube 5.

As can be better understood from FIG. 6, the plug 45 is
It has a hemispherical top shaped to fit into the cavity 43 and a cylindrical bottom forming a pseudo-annular groove 47 that can be forcibly fitted to the upper end of the tube 5. If desired, the plug 45 can be firmly connected to the tube 5 by means of a small transverse pin 49.

The inner surface and top surface of the cavity 43 are provided with a plurality of radial folds 51, 51' (third and twelfth folds) of mutually compatible dimensions.
(see figure) is desirable.

By providing the folds, the armpit table can be positioned at an angle with respect to the handle 9 (see FIG. 13).

Naturally, a device is provided for releasably fixing the axillary platform 39 on the plug 45 at the upper end of the upper tube when said plug 45 is fitted into the cavity 43.

The device may consist of a small bolt 53 inserted vertically through a hole 55 provided in both the central part of the underarm support 39 and the plug 45 and threaded into a nut 57 secured to the bottom of the plug 45. be. By unscrewing the bolt 53, the axillary platform 390 can be released to readjust the angle.

Alternatively, if desired, the underarm platform can be removed by completely removing the bolt 53, leaving the upper end of the tube 5 free for use as a hook when using the invention only as a cane.

As shown in FIG. 3, a pair of buffer sleeves 61, 61' made of a flexible material such as rubber and having rounded ends are inserted from the free ends 41° 41' into the central cavity so as to cover the T-shaped member 39. It may be forced to fit in the opposite direction. Sleeve 61.61'
are such that their cross-sections increase in dimension from the central part of the axillary platform, including the cavity 43, towards the free end 41,41' of the T-shaped member.

In order to simplify the sliding movement of the upper tube 5 into the central tube 3 and the central tube 3 into the lower tube 1, the upper ends of the tubes 3 and 1 and the lower ends of the tubes 5 and 3 are provided, respectively. Provide suitable guidance equipment.

As shown in FIGS. 3 and 6, the guiding devices provided at the bottom ends of the tubes 3 and 5 consist of small outwardly projecting scars 23, 23' forming an integral part of the plugs 14, 14', respectively. The skirt 23, 23' extends downwardly from the bottom of the plug 14, 14' and may be vertically slotted to provide greater elasticity, as seen in FIG. The skirt, made of the same plastic material as the plugs 14, 14', holds the bottom ends of the tubes 3 and 5 centrally positioned inside the tubes 1 and 3, respectively, and allows relative movement.

The guide device provided at the top of the lower tube 1 is made of plastic material. A sleeve 30 held at the upper end of the tube 1 cooperates with the skirt 23 of the plug 14 to hold the central tube 3 positioned centrally inside the lower tube 1.

3.5 and 6, a similar annular sleeve 31 of plastic material is placed at the upper end of the central tube 3 so as to slidably guide the upper tube 5 centrally within said central tube 3. will be established. A notch is provided in the annular sleeve 31 in the radial plane at 29 and extends integrally with the radially extending handle tube 25 on either side of the slit 29 .

The handle tube 25 with the walking cane handle 9 is integral with the sleeve 31 and is provided with a slit 27 along its longitudinal portion in alignment with the slit 29 of the sleeve 31 .

The handle tube 25 is provided with a releasable clamping device. The device includes a screw 35, as shown in FIG. It can be firmly tightened. By releasing the pressure on the screw 35, it is of course possible to release the sleeve 31 and remove the handle 9.

Advantageously, the handle 9 is provided with a buffer sleeve 37 made of a flexible material such as rubber and forced into the tube 25 of the handle 9. The sleeve 37 connects the sleeve 31 to the tube 25.
Preferably, the free end of the sleeve is hemispherical, with a cross-section that increases uniformly in dimension towards the free end. It should be noted that the outwardly tapered shape of the sleeve 37 is convenient for suspending the crutch and walking cane combination from a table by resting the handle 9 on the flat surface of the table.
