Description

LOADING KIT FOR SPEARGUNS
* * * * *
The present invention relates to a loading kit for spearguns, in particular of the rubber-propulsion type.
Spearguns essentially consist of a handgrip, a barrel, a shaft and a pair of rubbers.
Said handgrip is shaped likewise a pistol's handgrip and is provided with a trigger. It can also comprise a rear loading pad for said speargun, useful during the loading phase.
The shaft is provided with a tip at one end and with a shank at the other end.
The rubbers are steadily associated with the front end of said barrel and are provided with a mutual connecting element at their free ends. Said connecting element generally consists of a pair of ferrules screwed onto said rubbers and associated, by means of two pins coaxial thereto, with a pivoting bow, arranged for occupying engaging notches provided on said shaft.
Said spearguns further comprise a reel with a spool of line to recover said shaft.
When the speargun is loaded, the shaft surmounts the barrel and the shank is steadily constrained in a release mechanism housed inside the handgrip; whereas the pointed tip of the shaft protrudes frontally compared to the barrel.
On loading, the pivoting bow, associated to the rubbers by means of said pair of ferrules, is inserted into one of the engaging notches arranged near the shank of said shaft, in order to keep strain on the rubbers.
The fact that the user pulls the handgrip's trigger involves the release of the shank of said shaft from said mechanism; thanks to the rapid contraction of the rubbers, said shaft is violently propelled forward.
The above mentioned traditional spearguns have some disadvantages due to construction details that make it difficult the loading thereof.
At present the loading system provides for the user to lean the speargun's handgrip, that might be provided with suitable loading pad, against his/her breastbone or belt using them as counterthrust surface, while he/she gets hold of the ferrules and pulls the rubbers towards himself/herself, lenghtening them until the pivoting bow is engaged into the suitable notches provided on the shaft previously arranged on the barrel and inserted into the release mechanism.
This operation is very difficult:
- the sole hold of the ferrules with bare hands implies the risk that the latter slip from the hold, slowing down the loading phase and creating troubles for the user that is working in a free-dive condition and whose hands are wet and slippery;
- this loading system implies the user's considerable efforts and waste of energy since, for each rubber, he/she has to oppose a strain that can reach about 40 kg, having at his/her disposal a very narrow gripping surface;
- besides the speargun loading takes place in unstable conditions, most of all in case of moderate sea, deep sea, lack of supporting rocks etc ...
Aim of the present invention is to overcome these limits, making the loading operation quicker and easier, safer and less demanding in terms of physical efforts for the user.
The aims are achieved by means of a loading kit for spearguns, wherein said spearguns comprise: - a barrel;
- a handgrip provided with a trigger;
- a pair of rubbers;
- a shaft with a tip, a shank and at least one engaging notch for said pair of rubbers;
- a pair of ferrules screwed onto said rubbers and slidinghly associated, by means of two pins coaxial thereto, with a pivoting bow arranged for occupying said engaging notch;
- a reel with a spool of line to recover said shaft,
characterized in that said loading kit comprises a gripping handle provided with two projecting collars arranged for fitting, during the loading phase of said speargun, each in a groove provided in said ferrules.
According to a preferred embodiment of the present invention, said two projecting collars comprise two upside-down U-shaped forks and said groove comprises an annular channel located on each ferrule.
Advantageously said handle comprises two arms which extend on the opposite side with respect to said forks, and the axis of said arms belongs substantially to the plane containing the axes of said ferrules.
According to a further embodiment of the present invention, said handle comprises connection means arranged for allowing fixing thereof to a limb of the fisher. In particular said connection means comprise a threadlike element, one end of which is steadily associated with said handle, and the opposite end of which is provided with a loop arranged for fitting over said limb.
The loading kit for spearguns according to the present invention has numerous advantages. The coupling of the shape between the handle and the ferrules allows, easily holding the ends of said handle, easier strain of the rubbers until the complete loading of the speargun is achieved, thus obtaining easier engagement of the pivoting bow onto the shaft to be propelled.
The interaction between the forks of the handle and the grooves of the ferrules allows to leave the bow free for an easier engagement thereof into the notch in the shaft and for an easier removal of the handle at the end of the loading operation.
The risk for the ferrules to slip from the user's hands is eliminated and substituted with a comfortable handgrip: the user is thus facilitated in his/her movements and is not put under particular stress.
The shape of the handle, with the arms operating on the plane that contains ferrules and rubbers, allows to exert a perfectly axial strain on said rubbers, avoiding torsion and deformation thereof.
The speargun loading procedure thus defined is advantageously quicker and the whole spearfishing operation is more rapid, effective and possible also for users that are not very experienced or strong, and that were limited in practicing this activity before.
These and other advantages shall appear more clearly from the following description of a preferred embodiment, made by way of an indicative and non-limiting example, with reference to the figures, wherein:
Fig. 1 shows a sparegun according to prior art;
Fig. 2 shows, in a partial front view, the main components of the loading kit according to the present invention;
Fig. 3 shows, in a partially exploded axonometric view, the components of Fig. 2;
Fig. 4 shows the action of using the kit during the loading phase of the speargun according to the present invention.
Fig. 1 shows a speargun 1 of the rubber-propulsion type, according to prior art, composed by a barrel 2, a handgrip 3 and a shaft 7.
Said handgrip 3 is provided with a trigger 4 connected to a release mechanism 5 and with a loading pad 5 for said speargun 1 , to be used during the loading phase.
Said shaft 7 is provided at one end with a tip 7', and at the opposite end with a shank 7" arranged for engaging said release mechanism.
Said speargun 1 comprises a pair of rubbers 6 having two ends steadily associated with said barrel 2, and the two opposite ends being screwed into a pair of ferrules 9.
Said ferrules 9 are also slidingly associated, by means of two pins 10 coaxial thereto, with a pivoting bow 11 arranged for occupying an engaging notch 8, belonging to the shaft 7.
The speargun 1 shown is furthermore provided with a reel 12 with a spool of line to recover said shaft 7.
Figs. 2 and 3 show a kit useful for the loading of said speargun 1.
In particular said kit comprises a gripping handle 13 provided with a pair of projecting collars 14, made by two upside-down U-shaped forks.
Each one of said ferrules 9, having a substantially cylindrical shape, comprises a groove 15, shaped like an annular canal.
Advantageously, during the loading phase of said speargun 1 , said projecting collars 14 are arranged for cooperating with said grooves 15 to facilitate the stretch of said rubbers 6.
Said handle 13, made out of stainless steel and having circular section, comprises two arms 16 which extend on the opposite side with respect to said projecting collars 14, and the axis of said arms 16 belongs substantially to the plane containing the axes of said ferrules 9 and of said rubbers 6, in order for the force of traction exerted on the rubbers 6 to be perfectly parallel to the shaft 7 and to said rubbers.
Said handle 13 further comprises connection means 17 arranged for allowing fixing thereof to one of the fisher's limbs. Said connection means are formed by a threadlike element 19, one end 18' of which is steadily associated with said handle 13, and the opposite end 18" of which is provided with a loop arranged for fitting over said limb.
The method of use of the loading kit according to the present invention is described hereinafter.
The user leans the loading pad 5 of the hangrip 3 of the speargun 1 against his/her breastbone, with one hand he/she keeps the pivoting bow 11 associated with the ferrules 9 against tha shaft 7 and with the other hand he/she suitably positions the grippling handle 13, so as its pair of collars 14 fits into the correspondent grooves 15 provided into the ferrules 9.
Then, as better shown in Fig. 4, the user holds the side arms 16 of the gripping handle 13 and, pulling hard towards his/her own breastbone, he/she pulls towards himself/herself said handle and then the rubbers 6 until when the pivoting bow 11 associated with the ferrules 9 reaches the intended engaging notch 8 provided onto the shaft 7.
At last the user removes the gripping handle 13 releasing the grooves 15 of the ferrules 9 from the colllars 14 and continues the spearfishing operations.
Naturally, without prejudice to the principle of the invention, the embodiments, materials, dimentions and construction details may be varied with respect to the description and illustrations given, without straying from the scope of the present invention.
