CS247804B1 - Safety handle of skier's stick - Google Patents

Abstract

The safety handle with locking safety function is designed for all types of hiking or downhill ski poles. The handle can be left on or the safety function can be eliminated - the strap with the safety lock is pulled out, depending on the user's choice. To eliminate the safety function, it is enough to turn the stop in the safety lock to the longitudinal or transverse position by simple manipulation without tools. Using the handle according to the solution expands the number of functional options of the ski pole while fully respecting safety requirements.

Description

247804 2

The invention addresses the safety handle of a ski pole with the possibility of excluding a safety function from situations where this function is undesirable. The handle is universally applicable for ski and cross-country skiing. The vast majority of the known ski safety handle designs solve the problem of skier safety in such a way that when the stick plate is locked in, or when the stick is deeply immersed in the snow, with dangerous elbow and shoulder straining, the release of the strap from the handle. The strap is released after a predetermined or preset force is exceeded, the size of which is chosen so that the elbow or shoulder of the skier is not injured. Loosening the strap from the grip, then loosening the skier's wrist from a stuck or locked pole is important, especially when the skier rides faster. The strap is always released in the direction opposite to the normal hold of the ski handle and its control while driving.

The design of the handles and straps for this safety function are varied.

One of the simpler ones is to connect the ends of the strap with a press button that opens when the strap is released and releases the skier's wrist.

Another simple solution is to engage the strap shaped end piece in an appropriately formed flat spring located in the pole head. When the spring pressure is overcome, the whole strap is detached from the handle to release the wrist. Another useful solution is to push the thimble in the stick head, in which the cover part is rotatably mounted from above, the rotation of which is limited by the spring pressure. When pulling the strap in a direction opposite to that of normal pole control, the cover section rotates after overcoming the spring pressure and releases the end of the strap, which then slides out of the ru-koji head.

A common drawback of all these solutions is that the safety mechanism function cannot be ruled out. When using sticks, there may be situations where an undesired trip occurs, e.g. when transporting on a cable car, a lift, hanging a stick behind a strap. While waiting for a lift, when the sticks can be pushed by another skier and then unwanted shutdown. Furthermore, there may be occasions when the stick is to be used as a tow bar, eg towing, etc. In terms of practical use of the stick, the safety function of the handle and the strap is only required at higher speeds of the skier - at downhill, slalom, when with high speed If the sticks are locked in place, injury may occur. When walking on skis and in other "slow" situations, the possibility of injury due to sticks is almost impossible.

The drawbacks of using the non-detachable safety mechanism of the neborukojeti stiletto handle are solved by the locking handle according to the invention so that the safety function can be eliminated in a simple manner and actuated in the same simple way. To control the safety function of the locking or releasing mechanism, a 90 ° locking of the lock in the fuse by the edge of the strap or coin buckle is sufficient. The practical consequence of the solution of the handle according to the invention is the easy selection of the handle status - for a downhill with a safety function, a situation with the possibility of excluding the safety function. The solution also allows for a very clear control of the setting - by looking at the top surface of the drive and the position of the groove in the stopper, the skier immediately finds out the setting method. The invention is schematically illustrated in the drawings in which in Fig. 1 the locking device is closed, in Fig. 2 in the open position, Fig. 3 is a view of the upper surface of the disc, excluding the safety function, and Fig. 4 is the section AA of Fig. 3 excluding the safety function.

Claims (1)

3 247804 Locking handle. 2 is firmly tapped on the stick 2. Fuse 2 3e by rivet & coupled to the tongue 7a fits into the recess of the handle 2 · in the closed position, the fuse 2 is held by the tongue 1 resting on the support 2 by the riveted rivet 10 with the handle 2; the position of the pivot stop 5 in the groove 11 of the fuse 2 is such that it does not extend beyond the contour of the fuse 2 · When the pivot stop 2 is rotated, both ends of the fuse 2 extend beyond the fuse 2 and engage the grooves formed in the handle 2 · the function of the safety handle in a position to rotate the stop 2 does not extend beyond the contour of the fuse 2 in that the pulling of the strap 4 causes the tongue T to spring against the support 2 and tilt the fuse 2 in the direction of the thrust of the strap 6. In this case, the safety function of the fuse 2 connected by the rivet 9 to the strap 6 is maintained. By turning the pivot stop S in the groove 11 of the fuse 2 to the position overlapping the contour of the fuse 2, the ends of the pivot stop 2 engage in the grooves formed in the handle 2 · In this position, the safety function is excluded. OBJECT OF THE INVENTION A ski pole safety handle, in which a grip is fixed in a groove firmly attached to a stick, under which a rivet-fastened tongue fits to a lock connected to a strap, characterized in that it is rotatable in the groove (11) of the fuse (3) indent / 5 /. 3 drawings
