Abstract

The invention relates to a length-adjustable nordic walking pole or ski pole, comprising a lower pole member (1), an upper pole member (2), and a handgrip (3) attached to the upper pole member. The pole members (1, 2) connect to each other telescopically and the junction is provided with a manual locking mechanism (4) capable of locking a relative telescopic movement of the pole members (1, 2) at various adjusted pole lengths. The locking mechanism (4) is fixed to the top end of the lower pole member (1). The upper pole member (2) is provided with notches or recesses (2a) engaging the locking mechanism (4), the engagement thereof being releasable with a manually operable locking member (5). The notches or recesses (2a) are spaced from each other at distances matching a desired adjustment step. The upper pole member (2) passes through the locking mechanism (4) on its way into the lower pole member (1).

Description

Length-adjustable nordic walking pole or ski pole
The invention relates to a length-adjustable nordic walking pole or ski pole, comprising a lower pole member, an upper pole member, and a handgrip attached to the upper pole member, the pole members connecting to each other telescopically and the junction being provided with a manual locking mechanism capable of locking a relative telescopic movement of the pole members at various adjusted pole lengths.
Length-adjustable walking or ski poles are prior known e.g. from patent publications US-3,722,903, JP-7100240, US-3,556,544, EP-1321174, WO 03/095041, US- 6,354,629 and US-4,456,285.
All these involve one or several of the following drawbacks: Construction is complicated or inconvenient to manufacture, functionally unreliable, susceptible to breaking and/or awkward and slow to use.
It is an object of the invention to provide a length-adjustable walking pole or ski pole, having its length adjustment mechanism improved to make it simple in terms of fabrication, reliable in operation and easy to use.
This object is achieved with the invention on the basis of the characterizing features set forth in the appended claim 1. Preferred embodiments of the invention are set forth in the dependent claims.
One exemplary embodiment of the invention will now be described in more detail with reference to the accompanying drawing, in which
Fig. 1 shows the upper member of a pole of the invention in a perspective view and
Fig. 2 shows the pole of fig. 1 in an assembly view, the members being disengaged from each other. The pole comprises a lower tubular pole member 1 and an upper pole member 2, and a handgrip 3 attached to its top end. The upper pole member 2 can be fabricated by injection moulding and it can be tubular or in the form of a shaft. Its opposite sides are provided with notches or recesses 2a, spaced from each other at distances matching a desired adjustment step. The adjustment step can be e.g. 25 mm and the maximum adjustment e.g. 200 mm. Thus, the upper pole member 2 is very short with respect to the lower pole member 1 and, when the pole is at its shortest, the upper pole member 2 is in essence completely within the lower pole member 1. Hence, the pole members 1 and 2 join each other telescopically and the junction is provided with a manual locking mechanism 4 capable of locking a relative telescopic movement of the pole members at various adjusted pole lengths.
The locking mechanism 4 is fixed to the lower pole member's 1 top end. The upper pole member 2 passes through the locking mechanism 4 on its way inside the lower pole member 1.
The locking mechanism 4 includes a clamp type or U-shaped locking member 5 with springs 6 at the ends of its legs. The legs are sized to fit in the notches or recesses 2a. The locking member 5 has its end 5a protrude from the locking mechanism 4 and constitute a push button, the locking being releasable by pressing this button against the force of the spring 6 for the adjustment of a pole length. The locking member 5 has its legs 7 defining therebetween a space 8 converging toward the ends of the legs for the upper pole member 2 to pass through.
The locking mechanism 4 includes a housing 9 to accommodate the locking member 5 and the springs 6. From the housing 9 extends a fastening sleeve 10 for securing the housing 9 to the top end of the lower pole member 1, e.g. by glueing.
Thus, the housing 9 includes a hole for the upper pole member 2. This hole has its rim provided with a cog 8 which is fit for sliding in a slot or channel 11 and able to prevent the pole members 1, 2 from rotating relative to each other.
The slot or channel 11 has its bottom part provided with a detent 13, to which the cog 12 responds. The detent 13 is pushable over the cog 12 with a considerable application of force for connecting or disconnecting the pole members 1, 2 to or from each other, respectively.
It can be noted that the locking mechanism 4 is easy to use, because all it takes to release the locking is to press the push button 5a. Locking occurs automatically as the legs 7, in response to being pushed by the springs 6, snap into the notches 2a when the upper pole member 2 is moved in its lengthwise direction and the push button 5a is in its released position. The locking mechanism 4 is located sufficiently close to the handgrip 3 for an easy access to the push button 5a. The push button 5a can be located on the forward or rearward side of the pole. The position of a pole in the hand is determined by the handgrip 3 and a handstrap included therein. The handstrap, which is not shown, can be in any desired shape or form.
Various components of the locking mechanism 4 are also fabricated by injection moulding. The pole tube 1 may consist of a composite material, aluminum or some other appropriate material. The inventive length adjustment mechanism sets absolutely no limits regarding a fabrication material for the actual pole tube 1. On the other hand, the upper pole member 2 comprises preferably an injection- moulding fabricated tube or shaft, including said lengthwise slot or channel 11.
