(54) IMPROVEMENTS IN OR RELATING TO TELESCOPIC
FISHING RODS
(71) We, ESTABLISSEMENTS GARBOLINO
S.A., of "Les Rotes", Route de Sepmes,
Sainte Maure de Touraine (Indre et Loire),
France, do hereby declare the invention for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to telescopic fishing rods particularly intended for what is known as "ground-bait" fishing.
Traditionally telscopic fishing rods are constructed from a number of cylindrical glass fibre units of the same length, fitting into one another. Two consecutive cylindrical units can slide axially relatively to one another by way of two guidance components called reducers, one of which is formed as a sleeve integral with an external cylindrical unit and inside it; and the other is formed as a sleeve integral with an internal cylindrical unit and outside it. The reducer that is integral with the external cylindrical unit is mounted near to that end of it from which the cylindrical unit of smaller diameter emerges, whilst the reducer integral with the latter is mounted at that end of it which always remains inside the cylindrical unit of larger diameter.
These reducers ensure that the sliding movement of the two units relatively to one another takes place with frictional resistance so that the rod can be used whatever may be the relative position of these two units. On account of this a rod comprising seven units each one metre long may be used just as well with a length of 6.5 m.
as with a length of 4 m.
In every case these fishing rods comprise a tip of truncated shape which should itself be fully exposed. When the rods are made of glass fibre the reducers are usually of plastics material affixed by adhesive. Furthermore these rods comprise cylindrical rings mounted at the head of each cylindrical unit ensuring guidance of the fishingline. When the rod is completely telescoped these rings approach one another and for practical purposes are side by side.
In the known assembly, each line ring is attached by means of two small bars to a metallic collar of a diameter corresponding to that of the cylindrical unit on which the ring is to be mounted. These collars are fixed to the cylindrical units by adhesive, which is a relatively lengthy and delicate operation.
This technique also involves other difficulties. If, in fact, one of the cylindrical units should become faulty it is advisable to withdraw it from the back end of the rod, and to do this it is necessary to remove all the rings present on those cylindrical units whose diameters are less than that of the one to be changed.
This removal is effected by unsticking the collars, a delicate operation which has to be carried out at a rather high temperature and which adversely effects on one hand the collars initially mounted and on the other hand the cylindrical units, particularly in the case where they are of fibreglass.
It is the object of the present invention to remedy these difficulties.
According to the present invention, a telescopic fishing rod comprises a number of cylindrical units of different diameters with one unit slidable axially within an adjacent unit, guidance components being provided to guide two adjacent units, which are formed by a sleeve integral with the external unit and at least partially inside it, and a sleeve integral with the internal unit and outside it, rings for guidance of the fishng line being provided at one end of each unit, the end of each cylindrical unit featuring an externally-threaded portion at the place at which a ring is mounted, whilst the collar to which the ring is fixed features at least one internally-threaded portion allowing it to engage with the above mentioned external thread.
This solution has the advantage that the rings are mounted on to the different cylindrical units of the fishing rod simply by screwing on. This is a simple initial mounting, making possible a reduction of the selling price of the fishing rod as well as ease of maintaining the rod, for it is pos
sible to change a cylindrical unit easily and uickiy without causing deterioration of the fishing rod and of the collars supporting the rings.
fe*ly Xthe externally-threaded por
tw ,provi4ed the end of each cylindrical u-t is forked by a prolongation of the FjXnce component or reducer fitted into W tegrW with this end of the unit.
This solution is very attractive yet eczomical because it does not require any
modifications to the cylindrical units them
selves. It is clearly evident that the reducer
in question may be fitted in any normal manner, that is to say by adhesive or by
screwing on, according to circumstances.
Additionally, the internally-threaded por
tion provided in each collar that serves to
support a ring may consist of at least one
embossment protruding from the internal
face and produced by stamping. This last
solution has the advantage of being very
economical.
In a preferred form of construction of
the invention the externally threaded por
tion of each reducer is separated by a shoulder from the portion of the reducer
fitting into a cylindrical unit, the shoulder
pressing against the cross-section of this
unit. This arrangement is desirable because
the shoulder affords protection to the crosssectiqn of the cylindrical unit in question.
Moreover this shoulder forms with the external thread a wedge-type end to the base of the thread, in which the foremost embossnRent of the support collar can be jammed.
According to a further feature of the invention, the breadth of collar associated
with each ring is at least equal to the length
of the externally threaded portion of the cylindrical unit with which it is associated.
One embodiment of the invention will now be described -with reference to the acçarnpanying drawings, in which:
Figure 1 is a longitudinal section of two consecutive cylindrical units of the fishing
rod as at the time of mountillg a ring;
Figure 2 is a perspeqtive view of a reducer and~,the ring associated with it, before assembly; and ,Figure 3 is a perspectlye view of a re ducer and a ring associated with it, after 'ss;bly.
Jn the drawings, a fishing rod comprising a number of cyl5ndrical units of which 2 nd 3 are shown in Figure 1. The cylin
drical unit 2 is of greater cross-section than cylindrical unit 3.
For.relative displacement, apial guidance of these two units is effected by means of
two reducers 4 and 5 respectively. The re- duqer A is mounted inside cylindrical unit 2 and is integral with it .near to the end
from which the cylindrical unit 3 emerges.
As for the reducer 5, it is integral with that end of cylindrical unit 3 that remains inside cylindrical unit 2, and functions after the manner of a piston ring, the cylindrical unit 2 functioning as a cylinder.
The reducer 4, produced by moulding from synthetic plastics material, has a substantially cylindrical portion 6 which fits inside cylindrical unit 2. This portion 6 has bands 7 in contact with the internal surface of the cylindrical unit, separated by flutes 8 intended to be filled with adhesive.
The portion 6 of the reducer 4 is bounded by a shoulder 9 intended to press as shown in Figure 1 against the cross-section of cylindrical unit 2.
The reducer 4 presents a portion external to unit 2, comprising an external thread.
The base of the thread 10 forms ,at its end, a wedge 12 with the shoulder 9. On this thread 10 it is intended that a collar 13 should be fitted, bearing on its internal face an embossment 14 playing the part of an internal thread .It is dear that the breadth of the embossment 14 corresponds to the breadth of the base of the thread 10. Each collar 13 serves to support a ring 15 through which the fishing line passes, connection between the collar 13 and the ring 15 being effected via two small brazed bars 16. The internal diameter of the collar 13 corresponds to that of the portion of the reducer 4 external to the unit 2. Furthermore the width of the collar 13 is at least equal to the length of the threaded portion 10 in order to conceal the latter completely.
The collar 13 is assembled by screwing on the thread 10. Jamming is obtained by forcing the embossment 14 into the wedgeshaped extremity 12 of the base of the thread. The dimensions of the collar are so calculated that when jamming is obtained a small collar 17, partially bounding the extenral face of the collar 13 should be in contact with the end of the reducer 4, protecting it.
As is self-evident, the invention is not limited to the single form of construction of this fishing rod described above by way of example; on the contrary it includes all variations of construction embraced by the following Claims. Thus in particular the threaded portion on which collar 13 is engaged need not be an integral part of the reducer 4 but could for example be provided on the cylindrical unit 2 itself, or the reducer could be fixed into the cylindrical unit 2 by quite different means such as by screwing in, without in any way departing from the scope of the invention.
