DETAILED DESCRIPTION OF THE INVENTION

[0026] Fishing reels according to the present invention are preferably spinning reels that exhibit lateral connections for a handle assembly to accommodate the needs of right-handed, left-handed, and anglers who prefer to position the reel in a non-conventional manner. The fishing reel assemblies according to the invention continue to use frictional seals at each connection port but employ seals having a shape that allows the seal to angle radially inwardly to seal but rotate radially outwardly to disengage from sealing contact. The wall of a closure cap bearing the outside diameter threads that hold the cap on the reel body is used to engage an angled upper portion of the seal in a contact that applies a rotational pressure that urges the radially inward portion away from sealing contact with the handle connections thereby reducing the frictional forces on the rotation of the handle. A stationary seal in the closure cap engages the upstanding wall of the reel body that has the inside diameter threads that are engaged by the closure cap. This stationary seal protects the closed port against contaminant intrusion.

[0027] One skilled in this art will understand that the threaded connection between the closure cap and the reel body may use the opposite configuration of threads, i.e., the annular wall of the closure cap has threads on its inside diameter, and the reel body wall exhibits threads on its outside diameter. It should also be understood that the reel body wall and closure cap may use a twist-and-lock connection in which the closure cap wall disengages the seal from the handle connection shaft.

[0028] The attached figures are conveniently described with reference to the attached drawing figures. It should be understood that the same reference number is used to refer to the same parts of the device.

[0029] As shown in FIGS. 1-3, reel body 1 houses master gear 2 that is coupled with tubular handle connector, such as handle connection shaft 3, at threaded gear connection 4. Handle connection shaft 3 is supported by bearings 5, 6 that are fit into shoulders 7, 8 in reel body 1. Handle connection shaft 3 has a first opening 9 on a first side 10 of reel body 1 as well as second opening 11 on second side 12 of reel body 1. Both openings 9, 11 preferably have connector shaft threads 13 formed on the inside of handle connection shaft 3 of at least central portion 14. Preferably, threads are formed at both central portion 14 as well as outer portion 15. Central portion 14 and outer portion 15 may exhibit the same or different inner diameters. Preferably central portion 14 has a smaller inner shaft diameter 16 than the inner shaft diameter 17 of outer portion 15. Handle assembly 18 (partial view shown) should exhibit corresponding mating threads and diameters to allow use of handle assembly 18 on either the first side 10 or the second side 12. Closure cap 19 is used to close off the side that is not used by handle assembly 18.

[0030] First disengageable seal 20 is used on first side 10 at shoulder 8 between bearing 6 and first abutment 21 and encircling handle connection shaft 3. Inner annular wall 22 of cap 19 exhibits cap threads 23 that coordinate with corresponding reel body threads 24 on an inside diameter of inner wall 22 of reel body 1. When cap 19 is screwed into connection with threads 23, inner annular wall 22 contacts an outwardly inclined surface of disengageable seal 20 and urges seal 20 radially away from and out of contact with the outside surface 25 of handle connection shaft 3. Second disengageable seal 26 remains in contact with the outside surface 25 of handle connection shaft 3. Stationary cap seal 27 is urged against the outer edge 28 of reel body wall 29, thereby sealing off first opening 9 from intrusion by environmental contaminants. Because reel body 29 does not rotate, cap seal 27 is effective to seal without adding rotational resistance to handle connection shaft 3.

[0031] The same effect occurs when handle assembly 18 is alternatively used in the first opening (e.g., the left side) and closure cap 19 covers the second opening (e.g., the right side). First disengageable seal 20 is engaged and second disengageable seal 26 will be disengaged with handle connection shaft 25 thereby reducing friction and minimizing rotational resistance of the reel.

[0032] FIG. 4 illustrates greater details of a disengageable seal, such as first disengageable seal 20 that is the same or substantially the same as second disengageable seal 26. It is convenient to describe the relationships among the preferred shapes by reference to lower (as a reference to that portion of the seal closest to the interior of the reel) and upper (denoting that portion of the seal that is closest to the outside of the reel).

[0033] Seal 20 preferably exhibits a cross sectional shape having a lower base portion 30. Base portion 30 has a first outside diameter 31 that is larger than first inside diameter 32 and an outer height 33 that extends upwardly to seal shoulder 34. Seal shoulder 34 is desirably of a sufficient length to hold seal 20 between bearing 6 and shoulder 8 in seal retention cavity 35.

[0034] The inside diameter 32 of seal 20 is greater than the outer diameter of handle connection shaft 3 as it is unnecessary to contact an extended length of seal 20 against the outside of handle connection shaft 3 to seal the area from contaminant intrusion. Additionally, an increased contact surface area will also unnecessarily increase the friction acting on handle connection shaft 3.

[0035] Instead, the upper portion of seal 20 exhibits an inwardly-inclined portion 36 that extends inwardly from inside diameter 32 towards the outside surface 25 of handle shaft connector 3. Inwardly inclined portion 36 exhibits a length sufficient to extend over the inner wall 37 of seal retention cavity 35 and into contact with the outside surface 25 of handle shaft connector 3. Inwardly inclined portion 36 thereby forms second inside diameter 38 of a length that is slightly smaller, e.g., 0.001-2 mm smaller, preferably 0.01-0.08 mm smaller than the diameter of outside surface 25 on handle shaft connection 3 for effective sealing contact.

[0036] Opposite inwardly inclined portion 36 is outwardly-inclined seal shoulder 39. The angle of inclination of seal shoulder 39 is generally within the range of 10-90 degrees, preferably 25-60 degrees, and most preferably 30-45 degrees from vertical, the specific angle chosen to coordinate with the profile of the leading edge 40 of inner annular wall 22 of closure cap 19 to rotate inwardly inclined portion 36 radially outwardly and away from contact with outside surface 25 of handle connection shaft 3. As shown, leading edge 40 is substantially flat although this profile can be rounded or angled to reduce wear on seal shoulder 30 as closure cap 19 is tightened to close opening 9.

[0037] Intermediate, inwardly-inclined, outside portion 41 of seal 20 connects outwardly-inclined seal shoulder 39 with the outside wall 42 of seal shoulder 39. Outside wall 42 is more vertical than outside portion 41 and forms flexure junction 43 where these portions meet. It will be understood that seal 20 is a molded seal of a relatively soft and flexible elastomeric material to provide the desired sealing effect so flexure junction 42 is a location rather than a joining is disparate parts. When leading edge 40 of inner annular wall 22 of cap 19 descends and contacts outwardly-inclined shoulder 39, continued progress of leading edge 40 urges shoulder 39 downwardly and in rotation about flexure junction 43 thereby rotating the inward face 44 of inward-reaching portion 36 out of contact with outside surface 25 of handle connection shaft 3 thereby reducing the rotational friction associated with such contact when performing a sealing function.

[0038] FIGS. 5 and 6 illustrate an embodiment having groove 45 on the outside surface 25 at each end of the handle connection shaft 3 and below the normal contact location of the seal. It is noted that only one end is shown in FIGS. 5 and 6. In this embodiment, the leading edge 40 of inner annular wall 22 on closure cap 19 urges inward face 44 of seal 20 downwardly (using the perspective of the drawing) and into groove 45 thereby disengaging seal 20 from handle connection shaft 3.
