multipurpose paddle

Background technique

The invention relates to the field of paddles.

In particular the invention relates to a boat oar comprising a first rod having a first end and a second end opposite to each other, a first paddle fixed to the first rod and located along the longitudinal axis of the first rod at the extension of its first end , a female connector located at the second end of the first rod and oriented substantially along the direction of the longitudinal axis, the inner wall of the female connector having a housing adapted to receive data from a complementary male connector. Transversely telescopic member protruding from the connector to axially lock the connector.

In the field of boat oars, it is generally divided into single-blade oars and double-blade oars. Single-blade paddles consist of only a single paddle at one end of the shaft, usually with a supporting olive-shaped handle at the opposite end. In this context, "assisting olive handle" refers to a transverse handle that allows the palm of one hand to apply thrust along the longitudinal axis of the rod while the other hand is holding the rod. This type of paddle (called a single-bladed paddle) is used to propel small boats, such as rowboats, dinghies, canoes, or rafts.

On the other hand, single-bladed propellers are less suitable for propelling other types of small boats, especially kayaks, where so-called twin-bladed propellers are generally used, since a twin-bladed propeller consists of two blades, each positioned on a pole on one of the two ends. Two-bladed paddles have the ergonomic advantage of producing two pushes in the water for one cycle of motion of the paddler's arms, but they cannot be easily used in boats that are too wide.

In order to combine the advantages of single-blade and double-blade propellers, multi-purpose boat oars that can accommodate one or two blades have been specifically proposed in patent documents US 6,022,255 and US 1,817,414. However, in these multi-purpose paddles of the prior art, it is generally complicated to fit the accessories including the second blade on the paddle. In particular, as with two-bladed paddles, the two blades must generally be aligned at a specific angle relative to each other; the user typically must turn the two parts until the correct locking angle is found.

Contents of the invention

It is an object of the present invention to provide a multipurpose paddle in which receiving and locking of fittings in a female connection is simplified. This object is achieved in that the inner wall of the female connection of the oar has an oval recess oriented from the outer edge of the inner wall in the direction of the locking notch.

With these configurations, the accessory fits more quickly as the recess facilitates the correct insertion of the male connector of the accessory into the female connector of the oar, in particular aligning the retractable member of the male connector with the corresponding notch of the female connector to the paddle. Proper alignment of the two paddles is also better ensured when the accessory includes a second paddle.

In order to better assist the correct insertion of the fitting into the female connector, the oval recess may in particular have a depth decreasing in the direction of the notch and/or be substantially parallel to the longitudinal axis of the first rod.

The invention also relates to the above-mentioned paddle together with a fitting adapted to be attached in a connection at the second end of the first rod. The accessory may notably comprise a second paddle, thereby forming a two-bladed paddle. In this case, the fitting may also include a second shaft that is shorter than the first shaft, in order to obtain an ergonomically appropriate distance between the two blades, which is usually greater than the distance between the paddle and the olive handle in a single-bladed paddle but less than twice the same ergonomically appropriate distance between the paddle and the olive handle.

Furthermore, in order to facilitate the use of the oar as a single-bladed oar without complicating the insertion of the fitting into the female connector, the oar may also include an end piece attached to the second end of the first shaft. end piece and includes an assisting olive handle through which the female connector can be accessed.

Since the female connector can be accessed through the tail end piece including the assisted olive handle, it is not necessary to separate the tail in order to attach accessories (for example, a second rod with a second blade) to the oar through the female connector. end pieces. This facilitates the operations associated with the attachment and detachment of such fittings and reduces the risk of losing the end piece including the olive handle.

According to at least one first embodiment, the female connector may open on the outer surface of the olive-shaped handle. In this way, optional accessories can be attached to the female connection piece in a particularly simple manner via the olive handle. In at least this embodiment, the end piece may be attached to an outer surface of the first rod, which allows for easier assembly of the end piece and rod, while providing a wider cross-section for the female connector. In particular, the end piece can be divided longitudinally into two parts, which enables it to be attached on the outer surface of the first rod by connecting the two parts transversely with a stretched connector.

According to at least one second embodiment (alternative to the first embodiment), the olive-shaped handle is movable between a first position located in front of the connecting piece and a second position in which , the olive-shaped handle remains fixed to the first rod, but exposes the connecting piece. In this way, the removable olive handle does not interfere with the attachment of the accessory to the female connector, even though it is not detached from the oar.

In particular, the olive-shaped handle is displaceable by pivoting between said first position and said second position, which in particular has a pivot axis substantially perpendicular to the longitudinal axis of the first rod, the olive-shaped handle The pivot axis may more particularly be substantially perpendicular to the main axis of the olive handle. This pivoting allows the olive handle to fold back against the outer surface of the rod, thereby reducing the bulk of the olive handle when the accessory is attached to the female connector.

detailed description

A first embodiment is shown in FIGS. 1 to 4 . Referring first to Figures 1 and 2, there is shown a paddle 1 comprising a first shaft 2, a first blade 3 and an end piece 14 with an assisting olive handle. The shaft 2 has a longitudinal axis X to which paddles 3 and end pieces 14 are attached at opposite ends of the shaft 2 to form a single-bladed paddle, which the paddler grasps by grasping the shaft 2 with one hand and using the other Press on the olive handle to use the paddle. Typically, the rod 2 may be metallic, for example made of an aluminum alloy, while the paddle 3 and the end piece 14 may be made of plastic, ie a conformed polymeric material, for example by means of injection moulding.

In addition to the oar 1 , FIG. 1 shows an accessory 5 comprising a second paddle 6 and a second shaft 7 shorter than the first shaft 2 . As shown in Figure 2, this fitting 5 can be attached to the oar 1 to form a two-blade oar. The oar 1 thus comprises a female connection substantially aligned with the longitudinal axis X and accessible through the end piece 14 . Fitting 5 therefore also includes a male connection complementary to the female connection.

3 and 4 show the end of the oar 1 with the end piece 14 and the female connector 10 in more detail. Thus, in the present embodiment, the end piece 14 is divided longitudinally into two parts 14A, 14B, which are joined by a tension connection (not shown) in order to clamp the outer surface of the rod 2 . The inner wall 11 of the female connector 10 is formed by the inner surface of the hollow stem 2 , which continues the surface of the hole in the end piece 14 , opening on the outer surface of the olive-shaped handle 4 . As shown in FIG. 4 , the inner wall 11 is complementary to the outer surface of the male connector 8 of the fitting 5 in order to allow the male connector 8 to fit stably in the female connector 10 .

In order to be able to lock the male connector 8 in the female connector 10 , the inner wall 11 of the female connector 10 has a notch 12 adapted to receive a telescopic member 9 protruding laterally from the male connector 8 . In the illustrated embodiment, the notch 12 is formed by a through side hole in the rod 2 and communicates with a recess in the end piece. An elastic sheet covering this recess makes it possible to push the telescoping member 9 and thereby unlock the connectors 8 and 10 . In this embodiment, the telescopic member 9 is constituted by a folded spring.

In order to guide the telescoping member 9 towards the notch 12 when the male connector 8 is introduced into the female connector 10 , the inner wall 11 of the female connector has an oval recess 13 . The oval recess 13 (which provides a "keyhole" for the cross-section of the female connector 10) is oriented generally longitudinally towards the notch 12 from the outer edge of the inner wall 11 on the outer surface of the olive-shaped handle 4, and Its depth decreases gradually in the direction of the notch 12 . Thus, the recess 13 assists the user in placing the fitting 5 in a suitable angular position relative to the paddle 1 about its longitudinal axis X when starting to introduce the male connector 8 into the female connector 10 . The ramp formed by the decreasing depth of this recess 13 will then compress the telescoping member 9 until it reaches the notch 12, where it will protrude and lock the two connectors 8 and 10 together .

A second embodiment is shown in FIGS. 5 to 10 . Referring first to FIGS. 5 to 7 , there is shown a paddle 1 , also comprising a first shaft 2 , a first paddle 3 and an end piece 14 with an assisting olive-shaped handle 4 . The shaft 2 also has a longitudinal axis X, to which paddles 3 and end pieces 14 are attached at opposite ends of the shaft 2 so as to form a single-blade paddle which the paddler can grasp with one hand and use the other. The paddle is used with one hand pressing on the olive handle 4 . As in the first embodiment, the rod 2 may be metallic, for example made of an aluminum alloy, while the paddle 3 and the end piece 14 may be made of plastic, ie a conformable composite material, for example by means of injection moulding.

In addition to the oar 1 , FIG. 5 also shows an accessory 5 comprising a second paddle 6 and a second shaft 7 shorter than the first shaft 2 . As shown in Figure 6, this fitting 5 can be attached to the oar 1 to form a two-blade oar. The oar 1 thus comprises a female connection substantially aligned with the longitudinal axis X and accessible through the end piece 14 . The fitting 5 therefore also comprises a male connection 8 complementary to the female connection.

However, in this second embodiment the female connector does not open on the outer surface of the olive handle 4 . As particularly shown in FIG. 7 , the olive handle 4 is pivotally mounted on the end piece 14 . Thus, as shown in particular in FIG. 5 , the olive handle remains fixed to the rod 2 but exposes the female connection in its first position (in which it covers the female connection, but is available to apply a thrust in the direction of the longitudinal axis X of the rod) Pivot between the positions of the parts. In the embodiment shown in these figures, the axis Z of the pivoting olive handle 4 is substantially perpendicular to the longitudinal axis X, but also perpendicular to the axis Y parallel to the main axis of the olive handle 4, which makes it possible to reduce the The bulkiness of the shaped handle 4 in its second position. In the illustrated embodiment, the outer surface of the end piece 14 is concavely shaped to receive the olive handle 4 when the olive handle 4 is pivoted towards the second position.

Figures 8 to 10 show the end of the oar 1 with the end piece 14 and the female connector 10 in more detail. Thus, in the second embodiment, the female connection piece 10 is formed entirely by the end piece 14 . This female connector 10 also has an inner wall 11 complementary to the outer surface of the male connector 8 of the fitting 5 to allow the male connector 8 to fit stably in the female connector 10 , as shown in FIG. 9 .

In order to be able to lock the male connector 8 in the female connector 10 , the inner wall 11 of the female connector 10 also has a notch 12 adapted to receive a telescoping member 9 protruding laterally from the male connector 8 . In this second embodiment, the notch 12 is formed by a side hole in the end piece 14 and the telescoping member 9 is formed by a spring pin. In this embodiment, when the telescoping member 9 is received in the notch 12, it is accessible from the outside through the notch 12 so that it can be pushed inwards, thereby unlocking the male connector 8 and the female connector 8. The connecting piece 10 thus makes it possible to detach the fitting 5 from the oar 1 again.

In order to guide the telescoping member 9 towards the notch 12 when the male connector 8 is introduced into the female connector 10 , the inner wall 11 of the female connector has an oval recess 13 . The oblong recess 13 (which provides a "keyhole" for the cross-section of the female connector 10, particularly shown in FIG. 10 ) is oriented generally longitudinally from the outer edge of the inner wall 11 towards the notch 12 and has a depth along the The direction of the notch 12 is gradually decreasing. Thus, as in the first embodiment, when starting to introduce the male connector 8 into the female connector 10, the recess 13 assists the user in placing the fitting 5 in a suitable angular position relative to the oar 1 about its longitudinal axis X. The ramp formed by the decreasing depth of this recess 13 will then compress the telescoping member 9 until it reaches the notch 12, where it will protrude and lock the two connectors 8 and 10 together .

Although the invention has been described with reference to specific exemplary embodiments, it will be apparent that various modifications and changes may be made to these embodiments without departing from the general scope of the invention as defined in the claims. Additionally, individual features of different above-described embodiments may be combined in other embodiments. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
