SE529690C2 - Cap for tip of crutch or walking stick, contains slots for pins which are extended or retracted by turning twist sleeve - Google Patents

Abstract

The cap contains slots for holding retractable pins. An optical indication is provided for recognizing when the pins are extended or retracted. A twist sleeve is rotated in order to extend the pins and when they are no longer required the sleeve is rotated back into position so that the pins are kept inside the cap in a concealed position.

Description

It is therefore an object of the present invention to provide an improved solution with a dipping shoe which contains extendable light studs and which is very stable and easy to operate. The studs run in and out in slits in the dipping shoe. An optical indication shows whether the studs are extended or retracted in the dipping shoe. When it is slippery, turn the rotary sleeve to push out the studs. When the studs are not to be used, turn the rotary sleeve back again. The studs are hidden in the dipping shoe, while the attachment is very stable, which provides security for the user.

Description The invention consists of a dipping shoe, which contains extendable studs and which is very stable and easy to maneuver. The studs run in and out of slides arranged in the dipping shoe. Perpendicular to the upper part of the stud, there is a short cylindrical part that runs in an inner groove in a rotary sleeve. The studs are shaped at a small longitudinal angle to provide load stability. The inner grooves of the rotary sleeve are arranged as part of internal threads where the pitch is adapted so that the studs are pushed out sufficiently when the rotary sleeve is rotated to its end positions. The inner grooves in the rotary sleeve have a straight, non-ascending part at the beginning and the end, which means that the studs stay securely in their outer positions. An optical color indicator shows whether the studs are extended or retracted. The rotary sleeve is rotated to extend the studs. When the studs are not to be used, turn the rotary sleeve back again. The rotary sleeve is fitted on the outside with ribs for better grip, which facilitates rotation. The light studs are hidden in the dipping shoe, while the attachment is very stable, which provides security for the user.

An embodiment of the invention is described in the following and illustrated in the accompanying drawing, which according to Fig. 1 shows a perspective view of the immersion shoe and a part of the cane tube.

Fig. 2 shows a section through the immersion shoe with a folded-out stud.

Fig. 3 shows a perspective view of the rotary sleeve and its inner groove.

Fig. 4 shows a perspective view of a stud.

Fig. 5 shows a perspective from below of the immersion shoe with extended studs 10 15 20 25 30 529 690 Immersion shoe with extendable studs and which is shown according to fi g.1, 2, 3, 4 and 5 may represent the construction form used in this intended the example.

Dipping shoe with extendable studs according to figure 1 shows a perspective of the dipping shoe (1) with recessed studs (12) and a part of the cane tube (3). The dipping shoe (1) further consists of a frame (4) and a top (5). The top (5) has a recess (6) for reading color indications (7, 10) on the rotary sleeve (2). The rotary sleeve (2) has inner grooves (11) which form part of an internal thread where the pitch is adapted so that the studs (12) are pushed out and in sufficiently when the rotary sleeve (3) is rotated to its end positions. The rotary sleeve (2) is provided with outer ribs (8) for better grip, which facilitates rotation.

The rotary sleeve (2) is in its end positions further provided with optical color indications (7, 10) which show whether the studs (12) are extended or retracted. After mounting the swivel sleeve (2) and the studs (12) against the frame (4), glue the top (5) so that it holds the swivel sleeve (2) in place.

Dipping shoe with extendable studs according to figure 2 shows a section through the dipping shoe (1) with a connected cane (2) and a stud (12). Furthermore, it is shown how the stud (12) runs in the slide (18) in and out of the body (4) when the inner groove (11) affects the carrier (14) of the stud (12) when turning the rotary sleeve (2). The inside (19) of the body (4) encloses the lower part of the cane tube (3).

Dipping shoe with extendable studs according to figure 3 shows a perspective view of the rotating sleeve (2) with a core (9) and its inner groove (11), and how the rotating sleeve (2) in its end positions is provided with optical color indications (7) and (10) which indicates whether the studs (12) are extended or retracted. The grooves (1 1) in the rotary sleeve (12) have at the beginning and the end a straight non-rising part (17) which makes the studs (12) stay securely in their outer positions. The rotary sleeve (2) can also be manufactured in a transparent design, whereby you can directly see the studs (12) and whether they are outside or inside.

Dipping shoe with extendable studs according to figure 4 shows a perspective view of a stud (12) with an angled blade (13) which is integrated with a carrier (14). The angled blade (13) is formed in its lower part with a tip (15). .

Recovery * has been described in accordance with the preferred compilation and design and it is understood that certain exchanges and changes may be made without deviating from the spirit. In the embodiment now described, it is shown how the immersion shoe is provided with three studs. Alternative designs are possible, however, for example, anything from one to a number of studs can occur. Likewise, the stud can be square or have another shape. The invention shall thus not be taken as limited to what has been shown and described above, but such variants are included in the idea of invention and may be considered to be included within the scope of the appended claims.
