Definitions
- Pole intended to be used as training equipment during walking
- the present invention concerns a pole intended to be used as training equipment, in particular training the upper body of a user, during what is commonly known as “Nordic pole walking” or “trekking pole walking”, according to the introduction to claim 1.
- Poles of this type have long been known and are used during trekking on surfaces of varying nature, for example bare earth, snow or ice.
- the pole generally comprises an outer tube and an inner tube, which can be displaced telescopically one inside the other.
- a handle is positioned at the top of the outer tube, and a wrist attachment is arranged at this handle.
- a spring means that is arranged between the two telescopic tubes allows the inner tube, under a certain spring effect or shock-absorbing effect, to slide inside the outer tube when the pole impacts onto the surface.
- Common for known trekking poles is that they use conventional springs, normally metallic springs of spiral type, that generate their spring effect when the two telescopic tubes are displaced one inside the other.
- the shock-absorbing effect that the said springs offer is limited in that it solely contributes to increased comfort and a more constant load on the upper body of the user in which bumps and blows can be avoided, which means that joints and ligaments are subject to a lower load.
- One disadvantage of known poles that use springs is that they do not offer the resistance to motion that is desirable in order to achieve a more advanced training motion for the upper body, in which the muscles work through a significantly longer area of motion.
- one of the disadvantages of known trekking poles that use springs is that they have a limited area of motion for the spring effect (springs normally have a limited spring extent) and they require relatively complicated coupling means in order to hold together the two tubes that are components of the telescopic construction, one inside of the other, in a manner that limits motion.
- a rod is normally used, which extends through the centre of the spring and is connected between the outer and the inner tubes in a manner that allows sliding. See, for example EP 0 976 428 B1 and SE 522 840 C2, which known poles are limited in that they are simply "shock absorbing" poles.
- elastic bands have acoustic advantages in that they are, in principle, totally silent, and the elastomeric material has the advantage that it is deformed while demonstrating a linear spring characteristic with a certain degree of integral hysteresis, or delay, which gives a damping effect that means that the expression of the resistance of the pole to the user is constant and smooth.
- a pole-like training arrangement of telescopic type that uses the tensile elasticity of an extended elastic body, such as an elastic band, is revealed by SE 532 108.
- the pole has an outer tube and an inner tube, whereby the outer tube has a handle with an associated wrist strap.
- the extended elastic body is connected between the ends of the outer tube that face away from each other (the handle) and the inner tube.
- the elastic element extends essentially along the complete length of the pole, which not only means that the elastic element constitutes a bulky and - from an aesthetic point of view - ugly part of the pole in its entirety, but also introduces difficulties in achieving the desired resistance to motion between the two telescopic tubes without supplementary mechanical components, which include, for example, breaker wheels.
- a first purpose of the present invention is to achieve a pole that not only has a shock-absorbing effect, but also offers in a simple, elegant and efficient manner the resistance to motion that is desirable in order to achieve a more advanced training motion for the upper body, in which the muscles work through a significantly larger area of motion.
- a second purpose of the invention is to achieve a pole that demonstrates a simple, reliable and constructive design and that overcomes the disadvantages with which prior art arrangements have been associated.
- the insight that forms the basis of the invention is that a combination of continuous resistance to motion for efficient training and a discrete integration of an extended elastic element that operates between the telescopic outer and inner tube tubes can be obtained only through the extended elastic element being arranged to operate in opposing or neighbouring parts of the telescopically controlled parts of the outer tube and inner tube.
- a pole such as that defined in the claims, not only is a shock-absorbing effect obtained when the pole is placed in contact with a surface, but also a pole is achieved that offers the user a continuous resistance to motion through a significant area of motion, with the result that the pole can be used as more efficient training equipment for the upper body of the user than has been possible with prior art arrangements.
- the extended elastic element comprises an elastic band of, for example, rubber that operates between opposing parts of the telescopically active parts of the outer tube and inner tube.
- the extended elastic element is constituted by a tubular element that operates between the opposing ends of the telescopic tubes through a carrier that protrudes from one of the tubes, which carrier extends through the tubular element.
- Figure 1 shows a perspective view of an individual carrying out what is known as “Nordic pole walking” with a pole according to the present invention
- Figures 2a-2c show a series of longitudinal sections of different parts, in particular neighbouring parts of telescopically active parts of a pole in a first embodiment of the invention
- Figure 3 shows a longitudinal section of neighbouring parts of telescopically active parts of a pole in a second embodiment of the invention.
- FIG. 1 shows a person who, while training, uses a pair of poles according to the present invention, whereby the user is undertaking what is known as "Nordic pole walking".
- the poles are thus at an inclined angle backwards and, while the user carries out oscillating movement of the arms, the poles are placed down onto the surface just behind the relevant forward foot, whereby the user walks forwards.
- Each pole consists in principle of four main parts, which include an upper outer tube 1 , a lower inner tube 2 that can be telescopically inserted into a lower part of the outer tube, a pole handle 3 and a wrist attachment 4 at the upper free end of the outer tube 1 , together with a tip 5 arranged at the lower free end of the inner tube 2.
- the outer tube 1 of the pole with its handle 3 and the inner tube 2 with its said tip 5 are approximately of equal lengths.
- Figures 2a-2c show the component parts of the pole in more detail and, as the drawing makes clear, the lower end of the outer tube 1 demonstrates an end fitting 10 that at the same time forms a guide for the telescopic reception of the upper end part of the inner tube 2 through interaction with its peripheral outer surface.
- the said end fitting 10 is mounted at the lower end of the outer tube 1 by, for example, gluing.
- the upper end part of the inner tube 2 is arranged such that when the tip 5 of the pole is placed in contact with a surface it is displaced a certain distance from below into the lower end part of the outer tube 1 , for interaction with an extended elastic element, generally denoted by reference number 12.
- the said extended elastic element 12 is housed in a discrete manner and is active between the two end parts of the tubes 1 , 2 that meet telescopically, in order to form resistance to motion between the said telescopic parts when the tip of the pole 5 comes into contact with a surface.
- the external diameter of the inner tube 2 is so adapted to the internal diameter of the outer tube 1 that the upper end part of the inner tube can be displaced into the lower end part of the outer tube 1.
- a means 14 of limiting motion allows the two opposing ends of the tubes to be inserted telescopically one inside the other while at the same time preventing the upper end of the inner tube 2 from sliding in an uncontrolled manner out from the lower end part of the outer tube 1 and thus out from telescopic interaction with it.
- This means 14 of limiting motion comprises a stop screw 15 arranged in the end fitting 10.
- the stop screw 15 extends through a drilled hole 16 that is directed radially in towards the centre of the tube and it has its forward tip a certain distance inside a ring-shaped gap 18 that is limited between the outer tube 1 and the inner tube 2.
- the forward tip 17 of the stop screw 15 is thus located in the said gap 18 and, as a result, the inner tube 2 is prevented from sliding out from the outer tube 1 through interaction with the tip 17 of the stop screw 15 and a piston 19 arranged at the upper end of the inner tube 2.
- the length of the pole can be adapted to the height of the user.
- the recommended length of a pole of this type is normally approximately 70-80% of the user's height.
- the length of the pole can be adjusted, and for this purpose the lower inner tube 2 consists of two pieces of tube 2a, 2b (an upper and a lower) that can be telescopically displaced one inside the other (see Figure 2c).
- a telescopic lock 20 is mounted at the upper end of the lower part 2b of the said telescopic pieces of tube 2a, 2b.
- This type of telescopic lock 20 consists of a telescopic sheath 21 that is arranged such that it can be extended under tension with the aid of a wedge (not shown in the drawings, but located under the telescopic sheath) that can be turned into and out of the telescopic sheath 21 with the aid of a threaded shaft 22 that is attached at the upper end of the lower piece of tube 2b.
- An end fitting 23, similar to that described above, prevents the lower piece of tube 2b from sliding in an uncontrolled manner out from the lower end of the upper piece of tube 2a.
- the extended elastic element 12 can be taken up into and integrated in a discrete manner between the opposing parts or ends of the telescopic outer tube 1 and inner tube 2 that have been inserted one inside the other, without the ability to absorb significant telescopic movement between the two interacting ends of the tubes being limited.
- the extended elastic element 12 comprises thus an elastic band of rubber that is placed under tension (during which energy is stored) and forms resistance to motion when the end of the outer tube 1 and the end of the inner tube 2, which are placed one inside the other, are displaced one into the other, as is illustrated by the opposing arrows A-A in Figure 2b.
- a ring-shaped compartment 18 is limited between the opposing and telescopically active end parts of the outer tube 1 and the inner tube 2.
- the extended elastic element 12 extends through the ring-shaped compartment 18 and is active between the said telescopically opposing tubes 1 , 2 with an end 12a, 12b, respectively, and a part 12c.
- a first attachment means 25a for one end of the elastic element 12 is arranged at the end fitting 10 that is mounted externally at the lower end of the outer tube 1.
- the end fitting 10 demonstrates a channel 26 that leads in to a compartment 27 in the end fitting, in which the said first attachment means 25a is arranged.
- a corresponding attachment means 25b for the second end 12b of the elastic element is arranged in the diametrically opposing side of the end fitting 10.
- the extended elastic element 12 is drawn with a part 12c over an upper end part of the inner tube 2, which has been inserted into the lower end part of the outer tube 1 in order to achieve a telescopic effect.
- Each one of the two attachment means 12a, 12b comprises a combination of a tongue 28 arranged in the compartment 27 of the end fitting 10 and a removable yoke-shaped clamp 29 that can be led down over the tongue such that the clamp enters into locking interaction with one end 12a of the elastic element 12 that has been drawn over the tongue.
- the extended elastic element 12 runs in a controlled manner with the said part 12c over the upper end of the inner tube 2 in an attachment means 25c that is designed as a channel placed under the piston 19.
- the piston 19 can comprise a relatively soft material with low friction, for example felt.
- the piston 19 is attached at the upper end of the inner tube 2 through a piece of rubber 31 that is placed inside the tube. A threaded tube insert 32 of metal and a screw 33 that interacts with this are integrated into the piece of rubber 31.
- the piston 19 forms a guide for the forward end of the inner tube 2.
- the extended elastic element 12 is of band type and it has the said part 12c running over the upper end of the inner tube 2 and onwards down on the diametrically opposing side of the telescopic upper end part of the inner tube 2. It should be realised that it would be possible to equip the pole with a freely chosen number (n) of elastic elements 12, depending on the resistance to motion that is desired.
- Figure 3 shows an alternative embodiment of the invention, whereby the extended elastic band-shaped element described above has been replaced by an elastic tubular element 40, which is so attached in the opposing ends of the telescopic tubes 1 , 2 through first and second attachment means 41 , 42 that the elastic tubular element 40 offers resistance to opposing for the user when the tip 5 of the pole is placed into contact with a surface.
- a first piston 45 which may comprise felt, is attached at the free end of an extended carrier 46 designed as a rod, whose second end is fixed a certain distance into the outer tube 1 by attachment means 48 that are fixed by screws 47 such that the carrier 46, protruding from the lower end of the outer tube 1 , extends coaxially to the two telescopic tubes 1 , 2 of the pole.
- a second piston 48 which also may comprise felt, is attached at the upper end of the inner tube 2, which second piston 48 demonstrates at its centre an axial drilled hole 49 through which the carrier 46 runs when the two tube parts 1 , 2 move telescopically.
- the second piston 48 which is supported by the inner tube 2, is intended to slide inside the lower end of the outer tube 1
- the first piston 45 which is supported by the carrier 46, is intended to slide inside the upper end of the inner tube 2.
- the elastic tubular element 40 is attached at the ends 12a, 12b in the said first 45 and second piston 48 in such a manner that the tubular element extends coaxially between the two tube ends 1 , 2, which run telescopically one inside the other, and offers resistance to motion for the user when the tip 5 of the pole comes into contact with a surface.
- a certain portion of the carrier 46 extends along the central part of the elastic tubular element 12.
- a compartment 49 with the form of a ring- shaped gap is limited between the carrier 46 of the outer tube 1 and the inner surface of the inner tube 2.
- the elastic tubular element 12 can move in this ring-shaped compartment 49 (it can be placed under tension and released from tension) between the opposing ends of the telescopic tubes 1 , 2 and can thus offer resistance to motion when the telescopic tubes 1 , 2 are pressed together, such as when the tip 5 of the pole is placed in contact with a surface, which is to say, when the inner tube 2 moves a certain distance from below up into the lower end part of the outer tube 1 as a result of an impact against the surface.
