Description

Traininqsstock for athletes

The present invention relates to a training pole for athletes, such as Nordic walkers, joggers, goers, skaters or summer skiers, who move on a base in a running direction, with an elongated floor, at the lower end at least one wheel is arranged.

In recent years, motor sports, such as Nordic walking, running, jogging, skating or cross-country skiing became increasingly popular among the population, as these sports are healthy and in particular promote the physical well-being of athletes. However, these sports cause concentrated stress collectives in individual muscle and joint groups, which can eventually lead to physical damage. Through targeted exercise training on the one hand and through the use of tools on the other hand, such overloads are reduced. In order to further reduce the load on the corresponding muscle and joint Groups ^", the well-known tools are constantly being improved. For example, are known for the Nordic Walking training sticks mentioned.

In DE 20 2005 014 822 U1 a walking stick with a handle, a preferably telekopbaren stick shaft and a bottom-side foot is disclosed. The walking stick has on the foot at least one back-locked roller for the ground contact and the handle has a preferably perpendicular to the longitudinal direction of the stock shaft aligned handle.

Another training stick for athletes is described in EP 01744817 B1, which also has an elongated stick body, at one lower end of which at least one wheel is mounted, which allows a directed rolling movement of the training stick on the pad. The at least one wheel is equipped with a backstop, which allows rotation of the wheel in the running direction, but contrary to the direction locks. A disadvantage of the known training sticks is that often not the desired effect is achieved with them, since the athletes have the feeling of having to perform an artificial and unnatural movement, they then do not practice consistently enough. For example, after a certain period of time, usually after completing the instructional phase, Nordic walkers often only half-heartedly pull their sticks out without real support, which adversely affects the desired training success.

It is therefore the object of the present invention to propose a training stick, with which the disadvantages of the training sticks known from the prior art are eliminated.

This object is achieved by the training stick according to claim 1. According to the invention, a forearm rest is fastened to the upper end of the pole, the inclination angle of which is variable relative to the longitudinal axis of the pole and which can be pivoted against the force of a spring or an elastic restoring element to larger angles of inclination. The pivotable attachment of the forearm rest can preferably be realized by an articulated attachment of the forearm rest. Alternatively, a form of training into consideration, in which the forearm rest is fixedly or only slightly limited articulated pivotally attached to the upper end of the stick, wherein the invention according to the invention Eligible Eligible Verschwenkbar- speed of the forearm support is realized via an elastically deformable by bending the upper end of the stick. In this case, the pivotability of the forearm rest is not caused by a joint, but by corresponding bending deformation.

With the training stick according to the invention, a device is used which allows a visual image of a rolling movement, wherein the center of the rolling motion in or near the shoulder joint and the rolling contact path is formed by the ground on which the running movement takes place. In addition, the athlete wears a training stick according to the invention in each hand. The athlete now moves his arms in a rhythm that resembles that of Nordic walking Support forces on the sticks can increase significantly as the forearm pads relieve his wrists. In the backward movement of the arms of the preferably provided freewheel locked at the end of the stick, so that a force both upwards (support force) and forward (thrust) relieved or accelerated the barrel. In the forward movement of the arms of the training stick rolls, possibly through the freewheel load-free and noiseless forward and the athlete does not need to pick it up.

In the unused state of the training stock of the invention, the forearm support is arranged at an acute angle to the floor, depending on the training use, i. depending on the degree of flexion in the elbow joint, preferably increased up to 150 °. The resilient return member, which may be made of any elastic material, is preferably located below the forearm rest and is preferably secured under the joint between the stick and the forearm rest. The acute-angled arrangement always leads to a basic tension of the elastic restoring element or the spring when using the training stock according to the invention, which means that in each movement position, the wheel at the end of the stick is pressed onto the ground, which in use the lifting of the wheel from the ground prevented. The greater the angle between the stick and the forearm rest, the greater the contact pressure of the wheel on the ground.

The training stick according to the invention is a whole-body training device, which is pulled with the stick behind the body, always keeps ground contact and the aerobic training effect, namely walking and jogging, with the anaerobic training component, namely the static muscle training against resistance, connects. In addition, the entire back is stabilized by the parallel traction of the rollers and the back muscles are strengthened. The musculature of the shoulder-arm area and the chest belt is directly stimulated. In addition, the calorie consumption compared to traditional Nordic walking is significantly increased.

Thus, the training stick is an optimal whole-body training device for everyone and every terrain, which combines dynamic and static training modules. This training form is walking, running and can be used in all ages. Due to the supporting and stabilizing components, the training stick is also ideally suited for the medical rehabilitation area, because the large body joints are relieved and the cardiovascular situation (the cardiovascular system) is additionally strengthened.

Advantageous embodiments of the present invention are described below and in the subclaims.

So that the training stick further relieves the athlete, he can be adapted very closely to the kinematics of the movement and thus to the body size of the athlete. For this purpose, according to a particular embodiment, it is provided that the stick is made telescopic, for which purpose the stick consists of a plurality of tube elements which are insertable into one another and can be locked by a clamping element and / or a latching element and / or a thread adjustment. Further, a plurality of articulation points of the stick are preferably provided on the forearm rest, wherein the stick and the forearm rest are connected by means of a quick release. With these adjustment devices, the training stick can be optimally adapted to body size as well as the preferred posture by adjusting the length and position.

According to a preferred embodiment, the stick is at least partially elastic and / or the stick is bent. As a result, no jerky but a steadily built-up load is generated when building the support force, which is gentle on the stressed muscle and joint groups. Preferably, the stick is also formed such that in the load act the forearm automatically supported on a straight in the longitudinal direction and trough-shaped cross-section surface of the training stock, so that the wrists rest in the neutral position on a wrist shell and are relieved in power transmission.

Preferably, the training pole has two stops which limit the angle of inclination α between the forearm rest and the pole axis, the inclination angle α being 30 ° to 150 °. This restricts movement that no exaggerated movements can be performed with the training stick. The movement can thus not exceed the naturally given limits.

According to a further preferred embodiment of the training stock, the forearm rest is cup-shaped and partially includes the forearm and the wrist, with which the forearm shell ergonomically adapts to the contour of the forearm. This helps to avoid pressure sores on the forearm during longer training sessions, and the training pole can be comfortably positioned on the forearm.

Preferably, a handle element is arranged at the front end of the forearm rest, at the upper end of a knob is provided. The handle ensures that the training stick can be held tight so that it does not slide back and forth during training. At the rear end of the forearm rest, however, advantageously a clamping or coupling element is arranged so that the forearm is elastically positively connected to the forearm rest, so that a tensile force can be applied by the forearm even when forward swinging of the training stock. However, the clamping or coupling element can transmit only limited forces, beyond which the arms automatically loosen, so that in a fall no overloading of the arms or joints occurs. For example, such a clamp-type coupling element can be formed by two clamping jaws which comprise the forearm by more than 180 °. Alternatively, a Velcro closure band can be arranged, which completely covers the forearm and thus fixes it on the forearm rest.

Advantageously, the forearm rest is elastic in both the vertical and in the horizontal direction of force. As a result, on the one hand, the shock load when putting the training stock cushioned and on the other hand, the thrust when running in the forward direction is supported.

The springing of the forearm support is carried out according to a further embodiment of the invention by a tension spring and / or an elastomeric tape, wherein the tension spring or the elastomeric band is attached on the one hand to the forearm rest, preferably an armpit, and on the other hand to the stick. In order to make individual adjustments to the training stock, several attachment points for the elastomeric band or the tension spring on the forearm rest at different distances from the pivot point are provided so that the increase in force can be variably adjusted during rotation of the forearm rest. In the same way, preferably, the fasteners of the elastomeric band or the tension spring on the floor in the direction of the floor longitudinal axis are arranged displaceably or equidistantly.

According to a further embodiment, the holder of the elastomeric band is pulled under the tension spring on the stick by the band or spring tension in a clamp and thus ensures a self-locking displacement and adjustability.

A further embodiment of the invention provides that the pivoting angle of the forearm rest is detected by a driver and recorded in a counter, so that the total mechanical work of a training session is measured. Further, preferably in the stick an elastic element is integrated, which is compressed proportional to the load during application of the support force and allows the detection of the total work of the support force of a training session. The above measures serve to be able to determine when using the training stick each spent forces or work done in order to dose the training session meaningful.

Preferably, the wheel of the training stick is designed replaceable, wherein different wheels are provided for different floor coverings, which differ in diameter, in the material hardness and / or profile from each other. This allows the training stick to be used in different terrains, thus addressing the interests of different users. According to a particular embodiment of the invention, the return-blocking action does not attack on the wheel axle, but is generated via a support wedge on the tire surface. Finally, the stick can be made telescopic, so that the training stick can be used by people of different sizes or can be adjusted individually.

In a further embodiment, the training stick can have a non-circular, preferably oval contour, whereby unintentional rotation and tilting can be prevented when the telescope is telescoped into one another.

Finally, the training stick or a pair of training sticks has a band that can be fastened at both ends of the respective forearm supports, preferably with a quick-release fastener, so that this band can be guided from right to left behind the neck of the user when using the training stick or pair of training sticks. so that when you release the training sticks a fall is avoided.

According to a particular embodiment, it is provided that one or more freewheels are arranged in each skate for use in inline skating or roller skating in addition to or as an alternative to the freewheels in the wheel. Hereby, the athlete can now perform a form of movement in which he does not have to support himself laterally to prevent the roller skates rolling backwards, but he can roll directly forward, as the freewheels look similar to skins on skis. Thus, the movement patterns are less harmful to the hip joints and also produce a better muscle building effect. The same way roller skis can be equipped.

Overall, the training stick is a sports, exercise and exercise device that is used in jogging, running, on rollerblades, on cross-country skis and other devices to aid locomotion. With the training pole, a support force is applied to the floor over the arms and shoulders of the person exercising, so that on the one hand parts of the weight are directly supported, bypassing a load on the legs and the lumbar spine, and On the other hand, a forward force is transmitted to assist locomotion.

A specific embodiment of the training stick according to the invention is described below with reference to the figures. It shows

1a is a training stick in perspective view,

1 b is a side view of a training stick,

1c is a rear view of a training stick,

Fig. 2 is a schematic representation of a forearm rest and

Fig. 3 is a schematic representation of a movement sequence.

The training stick 1 essentially consists of a stick 2 at one end of which a wheel 3 is arranged on a wheel holder 3 '. At the other end a forearm rest 4 is articulated. So that the stick can be adapted to the height of the athlete, the stick 2 is designed to be telescopic. For this purpose, the stick 2 in the case shown consists of two tubular elements 5, 5 ', which are inserted into one another and can be fixed by means of the clamping screw 6. In addition, the rod 2 arranged in an articulated manner on the lower arm running position 4 is displaceable in the direction of the arrow 7 (cf., FIG. So that the inclination angle α does not exceed a certain angle, the stop 8 is provided at the front end of the forearm support 4.

In the illustrated case, the tubular elements 5, 5 ^{1 are formed} bent, which are reduced when placing the training stock 1 by the associated spring effect excessive shock loads.

A detailed view of the forearm rest 4 is shown in FIG. At the front end of the forearm rest 4, a grip element 21 is arranged, which in turn has a knob 22 at the upper end, which prevents unintentional slipping of the hand during exercise. At the rear end of the forearm rest 2, a clamping or coupling element 23 is provided which, in the case shown, consists of two Jaws 24, 24 'is formed, which include the forearm by more than 180 ° (see Fig. 1a, c).

The forearm rest is pivotally connected to the floor 2, wherein the floor 2 is also displaceable in the direction of arrow 7. In order to realize both adjustment options, the stick 2 is connected by means of the quick release 25 with the forearm rest 4, which engages bores at the articulation points 26, 26 '.

During a sequence of movements, which is illustrated by the male in Fig. 3, the inclination angle α varies from 30 ° to 150 °, wherein in the start position 31, ie in which the arm in the direction of movement, the maximum inclination angle α is assumed. In the position in which the arm is the furthest back (position 32), however, the inclination angle α assumes the lowest value.

So that the wheel 3 is pressed onto the ground during the backward movement by the force F, F ¹ and thus rolls on it, an elastic restoring element 27 is arranged on the forearm support 4, which acts in such a way that the angle of inclination α against the force of the return element 27 is increased. Alternatively, a spring may be provided.
