Non-slip

The invention relates to a non-slip bar for elbows and walking sticks.

It is well known that the head of the walking sticks is provided with spikes to prevent slipping. It should be noted, however, that most of the spikes prevent the use of sticks indoors and on exposed food. To solve this, 10 rotating blades have been invented.

A stick or rod is generally formed of a tube or wood with rubber attached to one of its heads. The rubber has a hole for inserting it into the end of the stick or tube. The rubber has a metal interior.

15 A metal plate is placed at the bottom of the rubber hole to support the rubbers so that the rubber does not break on the tube. Various spikes are used as anti-slip devices. There are different ways to install the spikes. One is that the outer circumference of the rubber is provided with vertical grooves along which the projections of the blade body with the inwardly bent tabs 20 can be inserted into the rubber. Once inserted into the rubber, it is twisted and the blade piece sticks to the rubber from the tabs of the protrusions. The spikes are directed downwards.

One solution is an anti-slip according to SE patent 206074 (A 43C 25 15/08). A suitable sleeve-shaped fastening part is fastened to the stick, for example with screws. The fastening part is provided with two holes turned to each other and with U-shaped grooves which are parallel to the sleeve. The ends of the U-shaped buckle have a loop bent at right angles to the buckles. The free ends of the straps are bent at a 90 degree angle outwards and threaded through the holes in the bottom of the grooves. The handles lie at the bottom of the groove and by pressing in, the handles can be removed from the grooves and turned 180 degrees. The spike is attached in the opposite direction to the brackets.

35 When the buckle is turned down, the spike is directly under the stick. The material of the spike is often wear-resistant.

When using crowns, snow may clump between the blades, after which there is no grip on the tines.

In order to eliminate this problem, the anti-slip device according to the invention is characterized by what is stated in the characterizing part of claim 1.

A significant advantage of the invention is that the spike can be easily turned into and out of the operating position, even without hands, using only a stick or a foot.

The invention is explained in the following to the accompanying drawings in FIG.

Figure 1 shows a side view of a stick rubber according to the invention, with a blade spike in the operating position and in broken lines in the protective position, to which the blade spikes are attached.

Figure 2 shows the rubber of the stick on one side, to which the blades are attached.

Figure 3 shows a screw hole made of rubber and a screw without 20 blade spikes.

Figure 4 shows a shaft screw hole made of rubber.

Figure 5 shows the end of the stick partially cut and enlarged with respect to the other figures.

Figures 6a, b and c show the structure of the spike when bent, folded on top and on the side.

Figure 1 shows a rod tube 2 with a rubber 1 attached to its head. A pivoting spike 6 with three blades 10, 11, 12 is then attached to the rubber 1. When the blade spike 6 is turned downwards, its spikes extend below the level of the lower surface of the rubber. . The spike 6 can move between two positions, of which the second 35 positions are shown in broken lines, whereby the anti-slip device is turned "off". Figure 2 shows the spike 6 in the up position from the other side. The spike is attached to the rubber with a screw 4 and a lock nut 5. The spike 6 pivots about the axis of the screw 4.

The hole 8 is made in rubber 1, as shown in Fig. 3. The screw is pushed into the hole perpendicular to the axis of the tube and substantially from the center of the tube and the lock nut 5 is fixed to the end of the screw. The lock nut holds the blade pin 5 6 to be installed, so that the screw does not come off when the pin is turned.

Figure 4 then shows a hole 8 made in the rubber 1 entering the end of the tube 2 with screws 4.

Figure 5 shows a partial section of the end of a pipe 2 to which a rubber 1 is attached. The rubber contains a metal plate 3, which usually has a hole 7 in the middle. The tube 2 is supported against the metal plate 3 when the rubber 1 is pushed from the hole 9 parallel to the tube into the end 2 of the tube. According to the invention, 15 holes 8 are formed in the rubber 1 perpendicular to the axis of the tube 2. A screw 4 is inserted inside the hole 8 to fasten the spike 6 to the rubber of the stick. The screw 4 is usually supported on the lower part of the plate 3.

In Fig. 6a, the spike 6 is illustrated bent away. The spike 6 20 consists of three steels 10, 11, 12 placed at both ends of the bent spike and in the middle. From the attachment of the spike 6, the spike 6 has bent convex holes 13, 14. When the spike is bent, it is fixed from the holes 13 and 14 with a screw 4 and a lock nut 5 to the rubber of the stick. By means of the screw and the lock-25 nut, the rotation of the spike 6 can be adjusted to a suitable power. When the blade is in working order, the spikes 10, 11 and 12 are downwards, and when the blade is not in working order, the spikes 10, 11 and 12 are directed upwards. The prongs 6 are thus preferably mounted outside the contours of the circumference of the stick head. In Figures 6b and 30c, the spike is shown bent from above and from the side.

In particular, it should be noted that the invention has been described above with reference to only one preferred embodiment thereof.

The attachment of the spike can be realized by various conventional fastening adapters, such as, for example, rivet, dowel, pin, wedge, etc. connections. The spike 6 can be removed when it is not needed, eg in summer.
