Fishing reel
FIELD OF INVENTION 
     The present invention relates to fishing reels having a control crank which consists of a hub arranged in the extension of a control shaft and supporting a lever transverse to the hub. One part of the crank is able, after releasing a sliding resilient bolt, to pivot around an axis transverse to the hub and in a plane containing the lever, in order to reduce the space occupied by the crank when no fishing is taking place. 
     BACKGROUND OF THE INVENTION 
     In such reels, an example of which is disclosed in French Pat. No. 1 351 573, the axis arranged transversely to the hub and around which a part of the crank pivots, is combined with the axis of the lever. The pivoting part of the crank hence consists solely of the manoeuvring lever, and the space taken up by the hub remains unchanged when, while not in use for fishing, the crank is folded to reduce its size. Moreover, the bolt which holds the crank in the in-use position, during fishing, can be unlocked by a thrust in the direction of the hub and the control shaft. This bolt may thus be actuated inadvertently when the fishing reel, assembled on the fishing rod, accidentally strikes against the ground causing folding of the crank lever. 
     SUMMARY OF THE INVENTION 
     The fishing reel according to the invention obviates or mitigates these drawbacks. In the reel of the invention it is possible, when it is not in use for fishing, to fold the crank to reduce its size in a much greater proportion than previously, the unlocking of the bolt maintaining the crank in the in-use condition being easy to operate, without, however, there being risk, during fishing, of an inadvertent unlocking of the bolt, as a result of an accidental impact against the latter, all these advantages being obtained by a reel mechanism which is at least as simple as known reels. 
     According to the present invention there is provided a fishing reel comprising a control crank having a hub arranged in extension of a control shaft and supporting an operating lever 6 transverse of the hub, one part of the crank pivotal, after release of the sliding bolt, about an axis transverse to the hub and in a plane containing the operating lever to reduce the dimensions of the crank, the reel being characterised in that a first part of the hub, which supports the lever, is connected at the transverse axis to a second part of the hub arranged in extension of the control shaft, the two parts of the hub being, in the in-use position of the crank, secured against relative pivoting by the bolt which can be displaced relative to the lever and/or the first part of the hub in directions at least approximately parallel to the lever, and which includes a profiled part constantly resiliently urged into engagement with a complementary profiled part provided on the side of the second part of the hub, opposite to that which supports the lever, another part of the bolt in the form of a push part being arranged on the external side of the lever to enable a voluntary sliding of the bolt against the resilient action to disengage the profiled parts. 
     The complementary profiled part may be on the side of the second part of the hub, which supports the lever, and the other part of the bolt, in the form of a push rod, is arranged on the internal side of the lever.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring to FIG. 1, the fishing reel/consists of a housing 1 containing the mechanism for driving of a drum 2 and a reel 3. The driving mechanism is controlled by a crank 4 having a hub 5 supporting an operating lever 6 arranged transversely of the axis of the hub 5. The free end 7 of the lever 6 mounts a knob 8 which is gripped by a fisherman to operate the crank 4. 
     Referring now to FIGS. 2 to 4, the hub 5 includes a first part 5&#39; which supports the lever 6, and a second part 5&#34; which is an extension of a control shaft 11 with which it is integral. This control shaft 11 has an end part which has a left hand thread 12 engaging a corresponding female screw thread provided in a toothed control wheel 13 which forms the first element of the kinematic chain of the driving mechanism for rotating of the drum 2. The rest of this mechanism is not shown in the drawing. The first part 5&#39; of the hub 5 includes, at its end opposite to that which suports the lever 6, two lugs 15 spaced from one another, the internal walls 16 of these two lugs 15 facing one another and being parallel to one another. The second part 5&#34; of the hub 5 has at its end remote from the control shaft 11, an axial lug 17, whose width is just sufficient to penetrate with a slight play between the two walls 16. The two parts of the hub 5 are relatively pivotal around a shaft 14 whose ends are forcibly fitted into the two lugs 15 and whose middle part pivots freely in a hole 18 of the lug 17. This shaft 14 is arranged perpendicularly to the lugs 15 and 17, and in a plane which contains the manoeuvring lever 6. 
     It is possible to prevent relative pivoting of the two parts 5&#39; and 5&#34; of the hub by a bolt 21. In this example, this bolt 21 is slidable to-and-fro in a direction 19-20 parallel to the lever 6 in a longitudinal groove 22 in the outer side of the operating lever 6 and a groove 23 in the first part 5&#39; in the hub 5 on the side opposite the operating lever. This bolt 21 consists of a bulbous push part 30 on the external side 6&#39; of the lever 6, which serves to support a fisherman&#39;s thumb, and a profiled part 24 which is constantly urged in direction 19 by a helical compression spring 26 into a hollow profile or notch 27 provided in the second part 5&#34; of the hub 5. This hollow profile 27, as well as the profiled part 24 which operates in conjunction with it, are arranged on the side 28 of the first part 5&#39; of the hub 5, opposite to side 29, which supports the lever 26. The sliding bolt 21 is kept in place in groove 23 by a lateral shaft 31 whose ends are forcibly fitted on either side of the groove 23 in the first part 5&#39; of the hub, and whose central part is fitted with a slight play in an axial elongate groove 27 in the bolt 21. The compression spring 26, which is housed under the bolt 21 inside the lever 6, is supported, at one end, on a fixed part 32 of the first part 5&#39;, and, at the other end, on a support element 33 of which one part 34, profiled in relief, engages with a hollow profiled part 35, of corresponding profile, provided in the bolt 21. This also tends to be held against the bottom of the guiding groove 22. 
     When fishing, the various elements occupy the position shown in FIGS. 1 to 3. The part 24 of the bolt 24 is pushed in direction 19 towards the free end of the lever 6 by the spring 26 in the hollow profiled part 27 of the second part 5&#34; of the hub 5. The two parts 5&#39; and 5&#34; are hence kept in alignment. The crank 4 is thus un-folded into its in-use position. It is noted that, in this position, an accidental impact along directions 19 or 36 on the bolt 21 cannot cause any inadvertent unlocking of the said bolt 21. 
     When not in use for fishing, the crank 4 can be folded by pressing the bolt 21 in the direction 20 against the action of the spring 26, for example with the thumb on the push part 30 of the bolt 21. This causes the part 24 of this bolt to move out of the profiled hollow part 27, as shown in FIG. 4. The crank 4 is hence free to be pivoted in direction 38 around the shaft 14 and to occupy the position shown in broken lines, in FIG. 1. The crank is thus reduced in bulk owing to the fact that a large part of the hub, the lever 6 and the knob 8 are folded against the drum 2. 
     In the second embodiment (FIG. 5) the bolt 21 is on the under side of the lever 6 and the part 24 and the cooperating hollow part or notch 27 are arranged on the same side 29 of the first part 5&#39; of the hub 5 as the operating lever. The spring 26 tends constantly to push in direction 20 the part 24 into the hollow part 27. The push part 30 is replaced by a push part 30&#39; arranged on the internal side 6&#34; of the manoeuvring lever 6. A cover 40 closes the side 6&#39; of the lever 6. All the other elements are identical to those of the first embodiment (FIGS. 1 to 4). 
     The operation of this reel is similar to that of the first embodiment. In the in-use position of the crank 4 (FIG. 5), no impact exerted along directions 20 or 36 on the bolt 21 causes unlocking of the crank 4. On the other hand, pressure in the direction 19 on the push part 30&#39; permits unlocking of the bolt 21 and folding of the crank, as shown previously in dotted lines, on FIG. 1. 
     The fishing reel, which is the ojbject of the invention, can be used in all cases where it is desired that a fishing rod should occupy as small a volume as possible when not in use for fishing.
