Description

TRAINING DEVICE, ESPECIALLY FOR GOLF SPORTS

The present invention relates to a training device, in particular for golf.

When learning and practicing the sport of golf, the athlete regularly encounters the problem that in the complex movement during the golf swing areas of the human musculoskeletal system are heavily used, which are usually not strained in daily life events overly. When performing a golf swing, however, due to the strong rotation of the trunk and shoulder area in conjunction with a pivotal movement of the arms to well above the head, a heavy strain on the musculoskeletal system extends to the leg muscles and tendons.

Often the learning of a technically satisfactory golf swing fails due to the lack of power of the muscle groups involved and / or the lack of extensibility of the particularly stressed ligaments and tendons. This is particularly noticeable in older athletes or golf beginners.

Apart from that, there is the problem that in golf due to lack of stretching and / or warming up before the execution of golf strokes repeatedly comes to strains or even serious injuries, especially in the back area. It is therefore desirable to provide an effective means of warming, stretching and generally strengthening the involved muscle and ligaments.

Apart from the specific problems associated with the practice of golf sports are lack of movement of the hip and / or back and / or shoulder and chronic back pain due to weak muscles in the back and / or hip area million times. Also in this regard, there is a need for a way to improve the mobility and strengthen the affected musculoskeletal system as a whole. The present invention is therefore based on the object to provide a training device that allows warming, stretching and strengthening of the entire musculoskeletal system of the middle body region and the upper body.

The above object is solved by the features of claim 1. Thereafter, a training device, in particular for golf, specified, which has a rod-shaped body made of elastic, displaceable in mechanical vibration material, wherein the main body has two opposite free ends, and the training device at the first end a holding area for gripping the device and the second End of a final part, in particular a weight having.

Advantageous developments of the training device according to the invention are the subordinate claims can be removed.

In accordance with the invention, the proposed training device simulates the loads acting on the body, which occur when holding and swinging a golf club. For this purpose, the training device is modeled in the construction of a golf club, namely, at one end of a rod-shaped body has a holding area and at the opposite end acting with a certain mass termination part.

The exerciser can be gripped by the user like a golf club. For this purpose, the user comprises the holding area, in particular a handle provided there, in the usual way with the hands, so that the closure part points obliquely downward away from the center of the body and, if necessary, rests on the floor.

The user can now simulate the implementation of a golf swing with the exercise device according to the invention. In accordance with the invention, the base body is formed of a material which is displaceable in mechanical vibrations. Therefore, the mass of the end part acts many times as compared with a conventional golf club. The user preferably takes an arbitrary position during the up or downswing of the swing movement and remains in this. Then, the user can, by gently swinging with the hands guide an oscillating motion of the termination part. Due to the oscillation of the final part of the comparatively large alternating forces are passed through the wrists in the body of the user and must be absorbed by the musculoskeletal system. Since the swinging motion can be initiated by the user in any position of the normal golf swing or in any other arbitrary posture of the exerciser, a training of the entire upper musculoskeletal system including the hip and at least the thigh region is possible.

The attitude of the device and the nature of the vibrations introduced by the user are not subject to any restriction. For example. The user can also put the terminal part of the training device in a circular movement, which in particular leads to an invigoration of the hand and forearm muscles.

Due to the spacing of the closure part from the holding region, the force exerted on the musculoskeletal system is particularly great, although no overload occurs due to the alternating and slow force build-up.

The exercise device according to the invention can be used excellently for training the musculoskeletal system and is particularly suitable with regard to the practice of golf.

Due to the design of the device made of elastic materials can also be done training of golf swings in the living area, without body or property damage due to lack of care to be feared.

Quite apart from the suitability of the device according to the invention for training purposes, this is also in an excellent manner for therapeutic operation for patients with chronic back problems and / or underdeveloped musculoskeletal system of the upper body, and is thus not limited to use in conjunction with golf.

The training device according to the invention therefore serves on the one hand for athletic training and on the other hand as an aid to therapeutic activity and indeed - A -

with and without instructions. The exerciser can be used to loosen up and train muscles and muscle groups. About an oscillating movement of the body, which has an alternating or circular movement of the end part result in alternating forces, which affect with appropriate handling on almost the entire body of the body.

Consequently, in the context of the present invention, a training device is provided, which allows a warm-up, stretching and strengthening of the entire musculoskeletal system of the middle body region and the upper body.

With regard to the base body, it is particularly preferred that this is made not only of an elastic, displaceable in mechanical vibrations material, but that it is rather formed of resilient material or spring-elastic material. Thus, the body is in particularly rapid oscillations with large amplitude displaceable, which demand the user a high training effort.

A particularly simple embodiment can be realized in that the main body or parts of the base body made of resilient plastic, preferably made of fiber-reinforced plastic.

In a particularly preferred development of the main body or parts of the body are made of fiberglass material. This makes it possible to realize a large deflection of the end part with a low mass of the base body.

The main body or parts of the basic body can preferably have a round cross section. A round cross-section has the advantage that the vibrations can be generated in all directions regardless of any orientation. Likewise, however, it is also possible to form the basic body, or parts of the basic body, with a flat, oval or polygonal cross-section, so that preferred directions are created with respect to the oscillations. This creates a special training effect. With regard to a simple production with low costs and the greatest possible stability, it is proposed that the basic body is produced in one piece.

Alternatively, with regard to a small pack size for the stowage of the training device or the entrainment of the training device when traveling, it is preferred that the basic body consists of two or more parts.

These parts of the body can be folded and in the unfolded state, i. in the operating state, be locked. This allows the training device to travel with ease and still be ready for use at the destination.

With regard to the greatest possible stability of the connection of the various parts of the base body, an embodiment is preferred in which the parts of the base body are directly or indirectly pluggable or screwed into one another.

According to a continuation of this idea, the parts of the basic body can be connected to one another via a sleeve, preferably a metal sleeve. Thus, the greatest possible stability of the joints is realized, but a somewhat increased effort in the assembly must be accepted.

In material terms, it makes sense to make the final part of plastic, rubber or the like. A soft, foamed material is particularly advantageous with regard to the targeted prevention of injuries. The material used should still have a significant volume-related mass, namely to be able to provide a final part with a desirable mass in a reasonable size.

In a particularly preferred development of the inventive concept, the end part has a striking surface which is inclined in an angle which is normal for golf clubs to the vertical (loft angle). Thus, on the one hand, the outer design of the training device according to the invention can be adapted to the appearance of the user of known golf clubs. This increases the user's acceptance of the use of the training device in conjunction with the sport of golf and thereby increases the joy of dealing with the training device. Furthermore even embodiments of the invention are conceivable with which normal golf beating (ie ball) can perform. At least embodiments are possible with which known golf training balls (which are generally balls with thin wall thickness, possibly where the wall has holes) beat.

In a continuation of this idea, an embodiment is proposed in which the impact surface has parallel grooves (grooves). This embodiment, in turn, reminds the user of conventional golf clubs and is expedient in view of the aforementioned possibility of sliding of training or even commercial golf balls.

With reference to the two aforementioned embodiments, a further development is favored, in which the base body assumes a golf club usual angle to the horizontal (LJe- angle) when placing the final part on the floor. A realistic lie angle automatically places the training device on the ground for a posture that corresponds to the level during the golf swing. The training procedure is thus more realistic approximated to the processes in golf.

In view of a user-friendly accepted optical design, an embodiment is preferred in which the final part has the shape of a golf club head, in particular an iron, wood or putter head. Accordingly, different sized or differently shaped club heads can accordingly also have different masses. With a designed as a putter head final part can be practiced real easy blows for poking the ball (so-called putting).

However, in general and non-golfing terms, the final part may take different forms. Concretely, the end part may be cylindrical or barrel-shaped with corresponding bulges. The shape of the end part can also be approximated from a cylindrical or barrel-shaped blank to the shape of a golf club head. by making from the blank a provided with a loft angle face.

Regardless of the specific shape of the end part, it is advantageous if this has rounded edge regions. As a result, the risk of injury and the risk of damage in the vicinity of positioned furnishings is significantly reduced.

In a further advantageous embodiment, the end part is interchangeable and are several end parts - for exchange - with different masses and / or head shapes and / or colors available. The flexibility of the training device is thus significantly increased, with different final parts or weights different levels of training can be defined. Furthermore, for example, a final part with bulbous shape and large mass can be exchanged for a final part in the form of a putter head, namely to practice real Pütts for a change. Different masses of the end parts can be characterized by an easily understandable color system.

In general, it is preferred that the end parts can be attached directly to the base body and that at the second end of the base body by a positive connection and / or adhesion and / or material closure. In this case, a combination of the claimed possibilities of very particular importance, namely to allow a secure attachment of the end part, wherein the attachment for the exchange of different end parts can be quite reversible. It should be noted, however, that particularly in the simulation of a golf swing quite considerable forces can act on the final part, so that a secure attachment is the top priority.

If a particularly secure fixing of the end part is given preference over a possible reversibility of the connection, it is proposed to glue the end part to the base body. Alternatively or additionally, the closure part can also be melted on the base body. Also, to bring about a gluing or merging the end part can be pushed or plugged onto the second end of the body. A reversible connection can be achieved by a Aufsteckvorgang, provided that the final part with appropriate bias on the body is plugged. So a frictional connection between the two parts would be realized.

In this regard, it is proposed that, in the case of elastic material of the closure part, an insertion channel formed in the closure part has an at least slightly smaller diameter than the base body for the base body. Thus, a corresponding bias voltage is produced, or is ensured in other words a strain of the insertion channel against the inserted body.

In a further embodiment, the insertion channel tapers from its opening to the interior of the closure part, preferably conically. Thus, high biasing forces are realized in particular in the lower end of the insertion channel.

With regard to a particularly secure, but nevertheless reversible connection between the end part and the main body, a development is proposed in which the end part has a plug-in channel for insertion of the second end of the main body, wherein the insertion channel extends through clamping means anchored in the end part.

In this case, the formed in the clamping means passage may have an at least slightly smaller diameter than the base body, so that when clamping the base body by the clamping means enters a clamping action.

In other words, very special clamping means are provided here in the closure part, which can partially or completely surround the insertion channel in the closure part, so that the second end of the base body is inserted not only into the insertion channel of the closure part, but inserted through the clamping means. By the passage of the main body through the passage of the clamping means, a widening of the clamping means and thus a clamping action between the clamping means and the base body arise. This clamping effect guarantees that inadvertent release of the closure part is excluded from the body.

The clamping means may be made of metal, preferably spring steel. Thus, a higher clamping effect can be achieved than by the rubber or plastic material of the closure part alone.

In terms of technology, it is advantageous if the clamping means are designed as a locking washer.

Concretely, the locking washer may be a slotted washer / clamping washer, the slots preferably extending radially from the passage to a self-contained peripheral area.

The locking washer can be designed and dimensioned such that the inner region comprising the slots during insertion or insertion of the base body inverts in the direction of insertion, so that a special clamping effect is achieved. This clamping effect is then automatically increased when the main body is to be pulled out of the insertion channel of the closure part. Then namely, the individual sections of the lock washer wedged with the surface of the clamp body, so that an inadvertent removal of the closure part - especially during use - is excluded.

If the final part is produced by injection molding or extrusion technology, the clamping means can be introduced into the final part during the production of the final part, thus, for example, fitting onto a mandrel which forms the insertion channel during the production of the end part. In any case, it is of very particular advantage if the clamping means or the locking washer is integrated in the final part and is there adhesively fixed as well as material fit or positive fit.

For better gripping and holding the body during use, a handle may be provided, which is arranged in the region of the first end of the base body. The handle can be made integral with the holding area of the base body. forms his. In view of a simpler production and a better interchangeability of the handle, however, it is preferable to provide the handle as a separate element which is connectable to the base body in one of the ways explained below.

The handle may be made of plastic, rubber, leather, leathery material, or a combination thereof. In this case, any material can be used which provides a non-slip gripping the training device and possibly also a sweat absorption.

It is preferable to apply a separate handle to the base body by pushing it onto the base body and / or to connect it to the base body in a positive and / or non-positive and / or material-locking manner in order to enable a secure holding of the training device.

Said handle may be formed as a substantially tubular sleeve around the first end of the body. Thus, the handle may also be a common handle for golf clubs, which is generally made of rubber-like material and has an opening for insertion of the base body on the side facing the base body. On the other hand, the handle has a lid to define an end point for the insertion of the body.

The handle can be glued to the base body. For this purpose, for example, double-sided adhesive tape can be used. To attach or remove the handle, the adhesive of the double-sided adhesive tape can be dissolved with solvent. Gluing the handle to the body ensures a secure grip of the handle and thus a secure holding the exerciser by the user.

For secure grip further offers an ergonomic design or profiling of the handle, wherein the handle should be at least dimensioned so that it can be operated in a conventional manner for gripping a golf club, namely with hands arranged one above the other. In a further expedient embodiment of the exercise device according to the invention, the handle has nubs on its surface. Such an embodiment of the handle has the advantage that it already sets a positive effect on the circulation of the holding hands during handling. The provision of the nubs leads from the outset to a constantly changing handle, so that in this respect cramps are avoided. Advantageously, the nubs may be distributed over the entire surface of the handle. It is also conceivable that the nubs in their entirety have a kind of ergonomic distribution with an adaptation to the human hand to better grasp the handle equipped with knobs. The nubs can be arranged in a line in the longitudinal direction of the handle, wherein the nubs can be formed approximately equidistantly from each other. The knobs can be integral parts of the handle, possibly where the handle with the knobs is injection-molding made of plastic or rubber. To set a desired massage or Entkrampfungswirkung the knobs can be made of a harder or softer material than the actual handle.

Finally, it is quite generally preferred that the training device has the mass and / or the mass distribution and / or the length of a golf club. The mass distribution of a golf club is also referred to as the so-called swing weight. This measure roughly indicates where the center of gravity is over the length of the club. The leaning of the training device according to the invention on the design of a golf club leads in a particularly advantageous manner to a realistic training experience and leads the user to increased acceptance of the device.

There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the claims subordinate to claim 1 and on the other hand to refer to the following explanation of several embodiments of the invention with reference to the drawings. In conjunction with the explanation of the preferred embodiments of the invention with reference to the drawings, also generally preferred embodiments and developments of the teaching are explained. In the drawing show 1 is a sectional side view of a schematically illustrated first embodiment of a training device according to the invention,

Body.

Fig. 1 shows a sectional side view of a particularly preferred embodiment of the exercise device according to the invention, which is particularly suitable for training for golf or more generally for therapeutic operation. The essential component of the training device is formed by a base body 1. The main body 1 consists of elastic material which can be set into mechanical vibrations, namely in particular of glass fiber reinforced plastic and / or glass fiber material. The main body has two opposite free ends 2, 3, namely a .erstes end 2 and a second end 3, on. At the first end 2 of the main body 1, a holding portion 4 is formed, which here has a mounted handle 5. The second end 3 of the main body 1, however, is connected to a termination part 6. For this purpose, in the present embodiment, the second end 3 of the base body 1 is inserted into the end part 6, resulting in a frictional connection. Form and / or cohesive connections are alternatively or additionally also conceivable. So offers It is important to glue the end part 6 in addition to the second end 3 of the main body 1.

The end part 6 is made of rubber-like material and serves as a weight to deflect the base body 1 with appropriate handling of the holding region 4 and thus to set it in vibration. In this case, a reciprocating motion or a circular movement or a mixture thereof can be generated at the user's choice in the base body 1, whereby a corresponding stress and strengthening of the musculoskeletal system of the user and thus a desired training and / or therapeutic effect can be achieved.

The handle 5 is made of rubber-like material and is mounted on the first end 2 of the base body 1. The handle 5 can also be glued. There are also positive connection techniques conceivable.

Fig. 2 shows a front view of the lower portion of the exercise device of Fig. 1, wherein the second end 3 of the main body 1 and the end part 6 are shown. Here it is easy to see that the end part 6 has been made from an originally clay-shaped blank. By removing a portion from the blank, a striking surface 7 has been formed, which is inclined in a conventional golf clubs angle to the vertical (loft angle). On the one hand, this embodiment of the end part 6 provides a suitable mass of the end part 6, but on the other hand the end part 6 also recalls a conventional club head of a golf club. By appropriate choice of material and suitable assembly of the training device is even conceivable to beat the training device according to the invention golf ball, but at least lighter training balls. If the end part 6 is designed in the form of a golf putter head, the training device is also suitable for training the puttering (putting) of balls.

3 shows a side view of an alternative embodiment of the end part 6 with inserted second end 3 of the main body 1. Here, the second end 3 is not introduced directly into an opening in the end part 6, but rather in the right region of the end part 6 a transition region 8 for receiving of the second End 3 trained. This transitional area 8 is also referred to as a hosel with respect to golf clubs. The transition region 8 basically has the shape of a plug-in channel 9 into which the second end 3 of the main body 1 can be introduced and glued and / or clamped. The end part 6 with the transition region 8 on the one hand provides increased stability of the connection between the base body 1 and the end part 6. On the other hand, this embodiment is even more reminiscent of the shape of a conventional golf club and thereby generates even greater acceptance by the user.

In Fig. 4 a final part 6 is shown in a partially sectioned side view, which corresponds in technical terms to the solution of FIGS. 1 and 2. For this purpose, the end part 6 no transition region, but rather directly in the final part 6 a plug-in channel 9 is formed, in which the second end 3 of the body 1 is inserted and possibly jammed there and / or glued and / or held in a form-fitting manner in any other way. This connection is particularly easy to implement. Furthermore, as far as the connection is made reversible, for example, by pure clamping - several end parts 6 vorhaltbar and quickly replaced. Thus, different end parts 6, for example. With different mass, can be used. If the end part 6 is held solely by a clamping action between the insertion channel 9 and the second end 3, the insertion channel 9 is expediently provided with an at least slightly smaller diameter than the base body 1 in the case of elastic material of the end part 6.

FIGS. 5 and 6 show an alternative connection technique between base body 1 and end part 6. For this purpose, a corresponding end part 6 is shown in a side view and partly in section. Referring first to Fig. 5, a plug-in channel 9 is provided in the end part 6 for receiving the second end 3 of the main body 1. This insertion channel 9 is inclined when placing the end part 6 on the floor in a usual golf clubs angle to the horizontal (Lie angle), so that the inserted body 1 - as in the previously described embodiments - occupies the same, realistic Lie angle , Here, the insertion channel 9 extends through anchored in the final part 6 clamping means 10 therethrough. The clamping means 10 are formed as a locking washer 11. The formed in the lock washer 11 passage 12 has a smaller diameter than the insertion channel 9 and therefore also a smaller diameter than the base body 1.

The lock washer 11 is made of metal, namely spring steel. It is designed as a slotted clamping disk, wherein the slots extend radially from the passage 12 to the self-contained edge region of the securing disk 11. The lock washer 11 has already been introduced during the manufacture of the closure part 6 in this, namely preferably by pouring during an injection molding process.

When inserting or inserting the main body 1, the inner region of the locking washer 11, which encompasses the slots, inverts in the direction of insertion, so that a particularly effective clamping effect is achieved. This clamping action causes inadvertent release of the end part 6 is excluded from the body 1. Nevertheless, the connection between the base body 1 and end part 6 is reversible, whereby an exchange of the end parts 6 remains possible.

With regard to further features which can not be inferred from the figures, reference is made to avoid repetition to the general part of the description.

Finally, it should be noted that the embodiments discussed above are illustrative of the claimed teachings, but are not limited to the embodiments. LIST OF REFERENCE NUMBERS
