- the footrest 31b or 61b is removed and the tube part 31a or 61a is passed through the recess 12 or 42.
- the two crutches 30 and 60 are moved relative to each other in height and the Insertion element 43 of the male part 40 is pushed into the recess 13 of the female part 10. Since the insertion direction 15 is arranged substantially perpendicular to the connection axis 50, the recess 13 and the insertion element 43 are clearly visible to the user from the front, so that a correct positioning of the two parts 10 and 40 presents no difficulties. In particular, no complicated head rotation is required to look from the side of the parts to be joined can. Due to the tapered configuration of the recess 13 and the insertion element 43, the inclusion is additionally facilitated.
- the bolt end of the locking member 20 contacts the chamfered surface 52.
- the bolt end is pressed into the hole 19 until it finally comes to rest over the recess 51, where the bolt 21 is pushed back outwards due to the spring force and finally engages in the recess 51.
- the stop 17 ensures that the insertion element 43 can not be moved beyond the end position.
- the two crutches 30 and 60 are now rotationally fixed and secured against each other connected. They form a stable bipod, which can be leaned against a stable application point located near the user, for example a table edge, a chair or a wall.
- the crutches 30 and 60 are supported in this case at least three points, so that the risk of falling over is reduced.
- the locking element 20 is actuated by the bolt 21 is moved by pulling the handle 23 to the outside, and the two Crutches 30 and 60 are separated by offsetting in height.
- FIGS. 10-13 are shown various views of a support member 70, which is optionally used together with the parent and male parts 10, 40.
- the support member 70 includes a support head 73 and a support leg 71 pivotally supported thereon.
- This includes an upper support member 71a having a rectangular cross section and a lower support member 72b having a U-shaped cross section and slidably received in the upper support member 71a.
- the support elements 71a and 71b form a telescopic support which is adaptable to the length of the supports 31 and 61 of the crutches 30 and 60.
- the end of the lower support member 71b is provided with a rubber foot 72.
- the holding head 73 comprises an axis 74 which is guided through a bore 75 at the upper end of the support leg 71 and fastened by means of screw 76.
- the support leg 71 is pivotable about the axis 74.
- the end of the support leg 71 has an edge 78 which is chamfered by the angle ⁇ relative to the longitudinal side 79 of the support leg 71.
- the angle ⁇ substantially corresponds to the angle about which the support leg 71 is maximally pivotable, and is preferably in the range of 15 degrees to 50 degrees.
- the holding head 73 further comprises a locking device with a spring 81 and a shaft 82 which is slidably disposed in a continuous slot 83, wherein the spring 81 presses on the center of the shaft 82.
- a locking device with a spring 81 and a shaft 82 which is slidably disposed in a continuous slot 83, wherein the spring 81 presses on the center of the shaft 82.

- the angle between the support leg 71 and the support 31 substantially corresponds to the angle ⁇ . If this angle selected at about 30 degrees, the ends of the supports 31 and 61 and the support leg 71 lie in the vertices of a substantially equilateral triangle, as this in FIG. 16 is indicated by the dash-dotted lines.
- the use of the support member 71 together with the parent and male parts 10, 40 has the advantage that the user can produce a stable tripod from the crutches 30 and 60 virtually anytime, regardless of the location, similar to a tripod for still cameras.
- the inventive arrangement is in a variety of types of crutches, especially forearm crutches, as shown in the Figures 14-16 and crutches can be used to form a tripod.
- the parts 10 and 40 may be provided with a plurality of parallel connections of insertion element 43 and recess 13.
- the base body 11 and 41 may be provided with a V-shaped groove in which the support 31 and 61 is fixed.

- Die Bohrung an der einen Krücke ist beim Zusammenfügen schlecht einsehbar, da die andere Krücke die seitliche Sicht teilweise verdeckt.
- Der Benutzer, welcher die beiden Krücken an den Handgriffen festhält und in Richtung der Krücken schaut,
kann die Lage der Bohrung schlecht einschätzen und hat daher Mühe, den Dorn in der zum Einfügen passenden Höhe zu positionieren. - Im Weiteren hat der Benutzer der Krücken in der Regel eine eingeschränkte Beweglichkeit, sodass es unter Umständen für ihn schwierig oder kaum möglich ist, den Kopf zu drehen, um in schräger Richtung die Bohrung erblicken zu können.
- The hole on one crutch is difficult to see when joining, because the other crutch partially obscures the lateral view.
- The user, who holds the two crutches to the handles and looks in the direction of the crutches,
can misjudge the location of the hole and therefore has difficulty positioning the mandrel in the proper height for insertion. - Furthermore, the user of the crutches usually has a limited mobility, so that it may be difficult or almost impossible for him to turn his head in order to see the bore in an oblique direction.
