Description

The invention relates to a paddle for swimming having a lower paddle blade and an upper wall for attaching the distal part of the user's hand to it.

When teaching swimming or training exercises, it is common to use a pair of hand-held swimming paddles to increase the paddling surface to better feel glide in the water and to correct movement and / or perform specific exercises to develop the muscles of the upper limbs in the water.

Such hand blades have various shapes and sizes depending on the desired effect, while they are extended under the distal part of the user's hand, in particular, only under at least one part of the hand and / or under the user's forearm, and their paddling area is greater than the paddling area of the specified distal part.

For positioning the hand blades during swimming, the latter are usually provided with a device made with the possibility of reversibly holding the distal part of the hand against the upper wall of the said blade.

For example, document EP 0844901 discloses a wrist blade secured at the user's hand by means of replaceable elastic links intended for an adjustable surrounding of the user's fingers and, accordingly, the wrist joint.

In particular, each elastic link comprises two free ends, respectively inserted into an opening through the blade to form an upper surrounding portion, each free end then being inserted into an adjacent opening to hold said link relative to the blade.

However, the installation of these links can be tedious, since it requires an adjustable insertion of these links into the holes, and the adjustment made is not reliable, since there is a risk of changing it and even losing the link during use of the blades.

US 3,258,794 also discloses a hand-held swimming paddle, the holding device of which comprises a hole passing through said blade and a rod sliding in said hole, said rod having a disc mounted at its upper end to provide axial retention of fingers thereon.

In particular, the rod is surrounded by a rubber sleeve for adjusting the height and / or inclination of the disc when placing the fingers. For this, the user can, in particular, press the disc with his hand after placing the rod between his fingers.

However, this solution is not completely satisfactory, since the sleeve does not provide sufficient reliability of keeping the fingers on the hand blade during its use, in particular, due to the load on the upper wall of the hand blade, which forces the fingers to move the disc away from the specified wall and, therefore , knock down the setting made during the initial placement of the specified fingers.

The invention is aimed at improving the prior art by providing a swimming paddle in which the holding device for the distal part of the user's hand can be easily adapted to the anatomy of the user's fingers while ensuring the reliability of said holding when using the paddle.

For this, according to the invention, there is provided a paddle for swimming, having an upper wall for attaching the distal part of the user's hand to it, and a lower paddle blade, wherein said hand paddle is provided with a device for holding the hand paddle on said distal part, and said device comprises a recess extending through said blade, and a device installed in said recess with the ability to move along an axis, and said device has a contact element located above the upper wall, while said contact element is configured to accommodate at least one finger of the specified user and contains means configured holding said at least one finger on said contact element, wherein said device is provided with an element elastically limiting its movement in the holding position of said at least one finger between the holding means and the upper wall, while said resiliently restraining element is located between the lower propeller blade and the device, and the specified element is made with the possibility of reversible compression between the extended state for placing the said device in the lower holding position of the specified at least one finger, and the compressed state for placing the said device in the upper position for placing the specified at least one finger on the contact element.

Other features and advantages of the invention will become clearer from the following description, given with reference to the accompanying drawings, which shows a hand-held swimming paddle according to the invention, respectively, in a perspective view from above (FIG. 1), in a top view (FIG. 2a) , in section along plane C of FIG. 2a (Fig. 2b), bottom side view (Fig. 3) and front view (Fig. 4).

In accordance with these figures, a hand-held swimming paddle is described below, typically used in tandem with another paddle, each being worn over the distal portion of the user's arm to improve swimming technique and / or to develop arm muscles.

In this description, the terms related to the location in space reflect the position of the vane in the drawings. In particular, the terms "front", "back", "left" and "right" refer to the left, right, bottom, and top locations, respectively, in FIG. 2a. In addition, the terms "axial" and "radial" refer to the axis A of movement of the holding device and correspond to a direction respectively parallel and perpendicular to that axis A.

In particular, the hand paddle is positioned so that it extends under the distal part of the hand, namely under at least one part of the user's hand and / or forearm, while leaving the elbow joint free for proper swimming movement.

The hand blade contains an upper wall 1 intended for attaching the distal part of the hand to it, while the specified wall can be flat or have a shape matching the shape of the specified distal part to optimize ergonomics.

Preferably, the top wall 1 is designed to support the distal portion of either the left or right hand of the user.

According to the drawings, the hand paddle contains a lower paddle blade 2 for improving propulsion in the water and optimal sliding feeling. In particular, the paddle blade 2 extends at least under the upper wall 1 and has dimensions exceeding the dimensions of the distal part fixed on the specified upper wall to increase its paddling area, and the specified paddle may additionally have an ergonomic shape that contributes to the stability of swimming. Alternatively, hand blades smaller than the size of the hand are known for practicing swimming techniques.

Preferably, the hand blade is rigid to provide optimal support and is formed in one piece, for example by injection molding, from one or a plurality of thermoplastic materials such as polypropylene or elastomeric material (SEBS). Alternatively, the hand spatula can be relatively flexible, for example with a mesh-type textile layer stretched over the frame.

In the illustrated embodiment, the hand paddle is sized to pass under the user's hand. Alternatively, the hand paddle may be specifically designed to only pass under the user's fingers, depending on the type of exercise that can be performed with the paddle and / or on the user's swimming level.

The hand spatula can be of different sizes and / or shapes, in particular depending on the shape and size of the hand and / or fingers, age and / or gender of the user. To this end, user categories can be predefined and standard sizes of a hand shovel can be defined for each of the categories.

As shown in FIG. 2b and 3, the upper wall 1 has a front surface 3 and a back surface 4, designed to accommodate the fingers and, respectively, the palm of the user, resting on them, with one of them being concave, and the second, respectively, convex, in order to fit snugly against the hand and provide comfort for the user. In addition, the blade 2 has a surface formed under the upper wall 1 and extending in particular under the front surface 3 and the rear surface 4.

In particular, a transverse plane T is defined for a hand blade, said hand blade being symmetrical about a sagittal plane B perpendicular to said transverse plane T, in particular to facilitate aligned positioning of the hand on said blade.

To hold the distal part on the upper wall 1, the hand blade is equipped with a device containing a recess 8 passing through it, in particular on the front surface 3, as well as a device 5 installed with the ability to move in said recess along the axis A.

The device 5 has a contact element 6 located above the upper wall 1, wherein said contact element is designed to accommodate at least one finger of a user and contains means for holding at least one finger thereon, in particular in axial and radial directions. In the illustrated embodiment, the contact member 6 allows it to be positioned between two fingers of a user.

In particular, the axis A of movement of the device 5 extends, when viewed from the front, along a direction perpendicular to the transverse plane T of the blade, and, when viewed from the side, forms an angle with said transverse plane, for example, from 0 ° to 40 °. In addition, in order to properly hold the hand blade on the user's hand, the device 5 is mounted on said blade so that it is possible to position the contact element 6 between the middle and ring fingers of the hand, in particular with an offset to the left or right relative to the sagittal plane B, depending on the hand, to be worn on which the specified hand paddle is intended. Alternatively, the same paddle can be used by positioning the contact member 6 between the index and middle fingers on one hand or between the middle and ring fingers on the other hand.

In the shown embodiment, the recess contains a slot 8 extending along the blade along the longitudinal plane C perpendicular to the transverse plane T. In addition, the device 5 extends in the plane C and is installed with the ability to move in the slot 8 along the axis A located in the specified plane C perpendicular to the transverse plane T.

In particular, the plane C runs parallel to the sagittal plane B with an offset to the right with respect to the specified sagittal plane for putting the scapula on the user's right hand with the arrangement of the contact element 6 between the middle and ring fingers of the specified right hand or between the index and middle fingers of the left hand. As an alternative not shown, plane C can be offset to the left of the sagittal plane B to fit the scapula onto the user's left hand with the contact member 6 positioned between the middle and ring fingers of said left hand or between the index and middle fingers of the right hand.

In addition, the device 5 is installed in the slot 8 and has upper and lower parts located, respectively, above the upper wall 1 and under the blade 2, while the said upper and lower parts form, respectively, the contact element 6 and the base 9 of the device 5.

The contact element 6 contains two opposite side surfaces 10, separated in the radial direction by the interdigital distance, while the said side surfaces are made to accommodate the corresponding lateral inner part of the finger with support, in particular by clamping the said fingers around the contact element 6 when they are placed on German

In addition, the holding means comprise two radial surfaces 7 extending on both sides of the contact member 6, each of said radial surfaces being adapted to abut against the upper part of the pin to axially hold it. In particular, the fixture 5 has two radial ribs 11 extending on both sides and from the upper end of the contact member 6, each rib 11 having a lower radial surface 7 intended to bear on the corresponding upper side of the pin. According to one embodiment, the radial ribs 11 may not extend parallel to the upper wall 1 of the hand blade.

Preferably, the longitudinal plane C forms a plane of symmetry for the device 5. In particular, the radial ribs 11 extend symmetrically on both sides of the contact element 6, and they are made with it in one piece, in particular they are solid.

In the embodiment shown, each radial surface 7 is shaped to also radially hold the fingers, namely, a curved shape to match the top of the pin on which it is to rest in order to improve the radial retention of said pin on the contact member 6, adjacent to said top side.

In addition, each radial surface 7 is a continuation of one side surface 10, in particular, it is connected to the specified side surface by means of a curved part 12, for better fit of the parts of the pin, which should rest on each of these surfaces. In addition, at least one side surface 10 and / or one radial surface 7 can be provided with a coating to ensure wearing comfort, namely a coating of a soft material, for example based on an elastomer.

The device 5 is provided with an element 13 elastically limiting its movements in the position of holding the fingers between the holding radial surfaces 7 and the upper wall 1, while the said fingers are, in particular, surrounded in axial and radial directions between the specified upper wall and the specified radial surfaces in the specified holding position ... The resiliently restraining element 13 can be made, in particular, of an elastomeric material such as rubber or silicone.

In particular, the resiliently restraining element 13 is located between the lower blade 2 and the device 5, said element being reversibly compressible between an extended state for placing said device in a lower position for holding fingers, and a compressed state for placing said device in an upper position for receiving said fingers on contact element 6.

Thus, when putting on the paddle, the user only needs to apply a manual force to the device 5 along the axis A in order to move it to the upper position in order to obtain a sufficient distance between the radial surfaces 7 and the upper wall 1 and thereby ensure that his fingers are placed on the contact element 6 ... For this, he can pull the contact element 6 upward, in particular by gripping the ribs 11, and / or push the base 9 and / or the element 13 upward.

With this movement, the resiliently restraining element 13 is in a compressed state, so the user only needs to release the device 5 to release it, and thus allow the said device to move to the lower position for holding the fingers due to the elastic return of the said element to its extended state.

In the shown embodiment, the resiliently restraining element 13 is attached to at least one part of the base 9 of the device 5 and has an outer dimension that is larger than the size of the recess 8, so as not to allow it to pass through the specified recess and, therefore, to be compressed when the device 5 is moved to the upper position ... More specifically, the member 13 is shown secured around the base 9. According to an embodiment not shown, the resiliently restraining member 13 may be integrally formed with the device 5.

In particular, the elastically restraining element 13 is made with the provision of an upper support on the blade 2, and is fixed from below with the provision of support at the lower end of the base 9, in particular, cast or assembled with the base 9. Alternatively, the elastically restraining element 13 can be cast or assembled with a lower blade 2 for attaching it to the indicated blade and to the device 5.

As shown in FIG. 2b, the base 9 has one recess 14 on the central axis and two lateral radial recesses 15 formed at its lower end, in which, respectively, axially and radially fixed an elastic limiting element 13. Alternatively, the base 9 can have at least one lateral a cruciform recess in which an elastically limiting element 13 is fixed.

In addition, the elastically restraining element 13 has at least one opening 16, in particular a plurality of openings 16 facing the lower end and / or the front and / or rear surfaces of the base 9 in order to facilitate its deformation into a compressed state and its elastic return to extended state.

Preferably, in addition to the openings 16, grooves, in particular two grooves, can be formed inside the element 13 in order to deform it in compression and thus eliminate the risk of separation of said element from the base 9.

In addition, as shown in FIG. 2b, the device 5 comprises at least one stop 17 formed at the lower end of the contact member 6, said stop abutting against the upper wall 1 to determine the nominal position of said device in the absence of fingers. In particular, the resiliently restraining element 13 is installed so as to be practically unstressed or slightly compressed in this nominal position, providing only the fixation of the device 5 on the wall.

In addition, in order to securely hold the hand on the upper wall 1 when using the blade, the elastically restraining element 13 in the extended state can maintain a compression sufficient for the force of pressing the fingers against the upper wall 1 by means of the radial surfaces 7. In particular, the device 5 can be located so that the stop 17 does not rest against the top wall 1 when the fingers are held under the radial surfaces 7.

The holding device may further include a strap 18a, 18b positioned so as to retain a portion of the distal portion of the hand that extends behind the user's fingers on the upper wall 1. In particular, when the hand paddle is intended to be worn over the entire arm of the wearer, the strap 18a, 18b may be positioned to hold the user's hand on the back surface 4 of the upper wall 1. In a preferred embodiment, at least one strap 18a, 18b is removable so that the hand blade can be used with or without it.

In accordance with the drawings, the holding device comprises two straps 18a, 18b, each of which has a lower end installed in a corresponding rear slot 19 of the scapula, said slots being made on the posterior surface 4 and symmetrical with respect to the sagittal plane B.

In particular, the first strap 18a has an upper end to which an adjustment buckle 20, for example made of plastic or metal, is attached by molding or assembly. In one embodiment, the first strap 18a may be formed by a portion of an elastomer molded over an adjustment buckle 20 made of hard plastic.

In addition, the second strap 18b has a free end 21 slidably mounted in an adjusting buckle 20 in order to adjust the length of the second strap by pulling out said free end, and thus, independently of the wearer, suitably press his wrist against the back surface 4 of the upper walls 1.

The straps 18a, 18b can be made of thermoplastic material or strong textile tapes, for example, based on nylon, while their lower ends are fixed in the slots 19. The straps 18a, 18b can also be slidably mounted in the slots 19, in particular , they have the lower ends reversibly locked in the indicated slots at the end of the movement.

In addition, the adjusting buckle 20 can be self-locking to provide quick pressing and unclamping. According to the drawings, namely FIG. 2a, the adjusting buckle 20 is made in one piece and has a socket 22 located between two longitudinal walls 23, an upper bracket 24 and a lower wall 25 connecting said longitudinal walls, with the specified socket limiting in the transverse direction.

The upper end of the first strap 18a is connected to the lower wall 25, while the second strap 18b is mounted in the seat 22. In particular, the seat 22 has a central axis 26 around which the strap 18b is slidably mounted, said strap engaging in both positioning slots provided on both sides of the specified central axis. The receptacle 22 is designed to allow the strap 18b to slide in the pressing direction by pulling its free end 21, as well as blocking sliding in the opposite direction in the absence of said pulling.

When the user wants to finally secure the hand paddle to his hand, it is enough for him to pull the free end 21 outward from the strap 18b to cause it to slide in the pressing direction. In addition, lifting the bracket 24 upwards allows the sliding in the opposite direction to be unlocked so that the hand paddle can be removed after use.
