Description

An attachable contoured grip for a badminton racket
Technical field of the invention
The present invention relates to a grip for the handle of a sports racket. In particular the present invention relates to a grip for the handle of a badminton racket which is provided for assisting, teaching and helping novices in learning the correct grip when learning to play badminton.
Background of the invention
In racket sports it is essential to have the correct positioning of the fingers when holding the racket during play. When the correct position of the fingers on the handle of the racket is used it makes it possible to learn the technical difficult and complex aspects, of moving the racket when striking the ball.
Even the way of holding the racket and the position of the fingers may seem much alike in the various racket sports, there are large and significant differences as the force transferred from the player through the racket to the ball are different, the weight of the rackets are different, the form and the weight of the ball are different, the games are different, etc. these many differences also requires special technical and unique details in each of the sports.
A traditional badminton racket usually includes a stringed surface within a head frame, and a shaft, which is connected to a handle. The racket handle is raditionally an octagonal column, which cannot show the correct way of the grip. The surface of the handle (handle surface) is provided with an overgrip to improve moisture/sweet transport and touch. If novices are not shown and instructed, they often use an inappropriate grip positioning. Even when shown the correct grip positioning they tend to turn their grip positioning, either consciously or unconsciously, to an inappropriate grip positioning
Tennis, squash and badminton share many similarities in regards to the positioning of the gripping hand - they all use an "open-fist"/"hello-grip". In order to gain a different striking approach, the handle is rotated within the hand, which consequently rotates the head frame as well. When rotating the handle, the fingers maintain the same position in respect to each other. A correct grip positioning is very important, therefore a device for helping the user to use an appropriate grip positioning is desirable. Several devices have been described, however, these are mainly provided and described for tennis rackets and squash rackets
As mentioned, badminton use the same "hello-grip" as tennis and squash, but when using the "backhand-grip" / "thumb-grip" in badminton, there is one significant difference. In badminton the thumb has a more longitudinally orientated placement, such that it almost points towards the head frame.
US 2012/0065007 describes a racket handle, which has a plurality of groove positions formed on the surface of the racket handle. These groove positions are a permanent part of the racket handle. The groove positions are intended to help the user to use the correct grip. These groove positions help teaching both the thumb-grip and the hello grip necessary when playing badminton. When using their device, the user will be used to groove positions and not a common octagonal column, which is the form of a traditional badminton racket handle and not possible to be removed from the racket.
US 2009/0011875 relates to a squash racket handle grip comprising at least an external surface and an internal surface, wherein said external surface includes raised surface ridges, wherein said raised surfaces ridges define (a) a forefinger receiving recess for receiving an index finger of a user's hand, (b) a first position site for receiving a thumb of a user's hand, and (c) a second position site for receiving a middle finger of a user's hand ; wherein said forefinger receiving recess is disposed on said external surface at an angle relative to both said first position site and said second position site. The disclosure of US 2009/0011875 describes a device for teaching the "hello-grip" but fails to allow and teach the "thumb-grip". Furthermore, it does not allow for contact between the grip and the skin of the hand and fingers.
US 7,758,455 describes a training grip for a tennis racket. The training grip has a series of protrusions and recesses that receive a user's hand and place it in proper position for a particular grip type. US 7,758,455 includes a universal training grip that allows the grip to be used for more than one grip type. The disclosure of US 7,758,455 describes a device for teaching the "hello-grip" and nothing is described or taught about the "thumb-grip".
Furthermore, US 7,758,455 does not allow for contact between the grip and the skin of the hand and fingers.
In the same way as being an important tool/device when learning the correct grip positioning when beginning to play, it is equally important to minimize the change experienced with the handle surface, when the tool/device is removed as the player also gets familiar with the specific racket and the handle surface, and the overgrip applied to the handle surface.
Hence, there is a need for a grip for the handle of a badminton racket that solves to disadvantages of the grips mentioned above with teaching and/or allowing both the "hello- grip" and the "backhand-grip"/"thumb-grip" and at the same time does not compromise the contact between the traditional shape, the handle surface and the feeling and touch between the handle surface and the skin, fingers and hand of the badminton player.

The present invention will now be described in more detail in the following.
Detailed description of the invention
Accordingly, if novices are not shown and instructed, they often use an inappropriate grip positioning. Even when shown the correct grip positioning they tend to turn their grip positioning, either consciously or unconsciously, to an inappropriate grip positioning . A correct grip positioning is very important, therefore a device, such as the grip according to the present invention, for helping the user to use an appropriate grip positioning is desirable.
A traditional badminton racket usually includes a stringed surface within a head frame, and a shaft, which is connected to handle with a handle surface, which may be provided with an overgrip providing the contact and the touch between the handle and the skin, fingers, and the hand of the player. The racket handle is a common octagonal column, which cannot show the correct way of the grip. If novices are not shown and instructed, they often use an inappropriate grip positioning. Even when shown the correct grip positioning they tend to turn their grip positioning, either consciously or unconsciously, to an inappropriate grip positioning
Tennis, squash and badminton share many similarities in regards to the positioning of the gripping hand - they all use an "open-fist"/"hello-grip". In order to provide a different striking approach, the handle may be rotated within the hand, which consequently rotates the head frame as well. When rotating the handle, the fingers maintain the same position in respect to each other.
Even though the grip positioning for tennis, squash and badminton, may have some similarities (all three sports uses the "hello-grip" grip positioning), badminton requires higher flexibility in grip positioning, as the grip may be changed constantly during play as the use of power provided by the fingers and the wrist to control, direct and accelerate the ball (shuttlecock) is required. Hence, in order to allow this high flexibility, it is preferred that the grip for the handle of a badminton racket should preferably be as simple as possible. In addition to the "hallo-grip", badminton also uses in particular a "thumb-grip" (also called a "backhand-grip").
This "thumb-grip" significantly differentiates badminton from tennis and squash as the thumb is more longitudinally orientated, in the "thumb-grip" relative to the shaft and handle of the racket, when playing badminton, than it is when playing in tennis and squash.
The essential difference from using the "backhand-grip" / "thumb-grip" in badminton, relative to the grip positioning used in tennis and squash, is that the thumb is allowed to have a more longitudinally orientated placement, such that it almost points towards the head frame. Thus, the inventor found that the traditionally provided grips does not provide the proper flexibility and grip positions when playing badminton, however, the inventor of the present invention surprisingly found a device/grip, as described herein, that would be suitable for badminton as it solved the above problems. Hence, a preferred aspect of the present invention relates to a grip for the handle of a badminton racket, wherein the grip comprises a longitudinal contoured part, an upper contoured part and a lower contoured part, wherein the longitudinal contoured part defines a position of the thump finger; the upper contoured part, the lower contoured part and the longitudinal contoured part provides an area defining a position of the index finger; and the lower contoured part defines a position of the middle finger.
The inventor of the present invention also found that by increasing the surface area of the handle surface available for direct contact to the skin, the fingers, and the hand of the player, the easier it was for the player to maintain proper grip positioning when starting to play without the grip for the handle of a badminton racket.
In an embodiment of the present invention, the grip is an attachable/detachable grip. This allows the user easily to move, remove/detach and/or attach the grip as desired . One advantage of the attachable/detachable grip according to the present invention is that there are no need for specially developed rackets and the same racket may be used with and without the grip according to the present invention.
