## Background
RELATED APPLICATION
The present application is based upon U.S. Provisional Application No. 61/396,804 filed Jun. 3, 2010, 61/517,969 filed Apr. 28, 2011 and 61/518,198 filed May 2, 2011 the subject matter of which of applications is incorporated herein by reference.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved locking stopper component and more particularly pertains to selectively locking/sealing and uncovering of a fluid reservoir in a secure tamper-free manner while precluding leakage when the tank/reservoir is tipped into an unintended orientation.
2. Description of the Prior Art
The use of stopper components is known in the prior art. More specifically, stopper components of known designs and configurations previously devised and utilized for the purpose of precluding leakage of and tampering with fluids from tanks/reservoirs are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the prior art which has been developed for the fulfillment of countless objectives and requirements.
In this respect, this locking stopper component according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of selectively locking/sealing and uncovering of a fluid reservoir in a secure tamper-free manner while precluding leakage when the tank/reservoir is tipped into an unintended orientation and with contracting sealing components for ease of insertion and removal.
Therefore, it can be appreciated that there exists a continuing need for a new and improved locking stopper component which can be used for selectively locking/sealing and uncovering of a fluid reservoir of a tank while precluding leakage when the reservoir is tipped into an unintended orientation. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of stopper components of known designs and configurations now present in the prior art, the present invention provides an improved locking stopper component. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved locking stopper component and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises an upper extent, a lower extent, and a central extent between the upper and lower extents. The component has a normally vertical central axis. The component is in an essentially symmetrical configuration about the central axis.
The lower extent includes an elongated dipstick with a frusto-conical cam shoulder formed in a central extent of the dipstick. The dipstick has a radial bore there through above the shoulder.
The upper extent includes a lock. A key is provided for insertion into the lock for rotation between locked and unlocked positions. The upper extent also includes an upper shaft having a threaded recess above for threadedly receiving the lock. The lock has a square projection below. A flat washer or seal and a spring insure the sealed positioning of the upper shaft and the lock.
The central extent includes a reciprocating assembly and a rotatable assembly.
The reciprocating assembly is formed of a split cylinder, a sealing cylinder, and a cam cylinder. The sealing cylinder is located above and exteriorly of the split cylinder. The cam cylinder is located beneath and interiorly of the split cylinder. The cam cylinder has a downwardly facing spiral surface in contact with the shoulder of the central rotatable member whereby rotation of the central rotatable member and cam shoulder will cause the cam shoulder to ride along the spiral surface to translate the rotational movement of the shaft and cam shoulder into axial reciprocating movement of the reciprocating assembly. A lower split ring encircles the split cylinder at a lower extent.
The rotatable assembly is formed of an interior drum above and an exterior drum below and the upper shaft and the dipstick. A radial bore extends through the interior drum and the exterior drum and the upper shaft and the dipstick. A cylindrical roll pin extends through the radial bore to ensure concurrent rotational movement of all components of the rotatable assembly and to preclude relative axial movement between components of the rotatable assembly. The exterior drum is formed with an upper chamfer and a lower chamfer. An upper split ring encircles the split cylinder at a lower extent.
Next provided is a sealing assembly formed of an upper sealing component and a lower sealing component. The upper sealing component is located between the upper chamfer and the interior drum. The lower sealing component is located between the lower chamfer and the sealing ring. In this manner, rotational motion of the rotational assembly will translate to axial raising of the reciprocating assembly to compress the O-rings and seal the component in the neck of an oil reservoir.
A repositionable cap is next provided. The repositionable cap is positioned above the interior drum. The repositionable cap has a lower portion with a securement ring. The repositionable cap has a shiftable upper portion. A pivot pin couples the upper and lower portions. An L-shaped leg is formed in the upper portion to contact the securement ring during closing of the repositionable cap. A top O-ring ensures sealing of the upper and lower portions.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved locking stopper component embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the locking stopper component 10 is comprised of a plurality of components. Such components in their broadest context include an upper extent, a central extent and a lower extent. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
The locking stopper component 10 is for selectively locking/sealing and uncovering a fluid reservoir of a tank/reservoir in a secure tamper-free manner while precluding leakage when the tank/reservoir is tipped into an unintended orientation. The locking/sealing and uncovering and the precluding leakage is done in a safe, convenient and economical manner.
First provided is an upper extent 12, a lower extent 14, and a central extent 16 between the upper and lower extents. The component has a normally vertical central axis. The component is in an essentially symmetrical configuration about the central axis.
The lower extent includes an elongated dipstick 20 with a frusto-conical cam shoulder 22 formed in a central extent of the dipstick. The central rotating member has a radial bore 24 there through above the shoulder.
The upper extent includes a lock 28. A key 30 is provided for insertion into the lock for rotation between locked and unlocked positions. The upper extent also includes an upper lock housing 50 having a threaded recess above for threadedly receiving the lock. The lock has an oval projection 34 below. A flat washer or seal 36 and a spring 38 insure the sealed positioning of the upper shaft and the lock.
The central extent includes a reciprocating assembly and a rotatable assembly.
The reciprocating assembly is formed of a split cylinder 40, a sealing cylinder 42, and a cam cylinder 44. The sealing cylinder is located above and exteriorly of the split cylinder. The cam cylinder is located beneath and interiorly of the split cylinder. The cam cylinder has a downwardly facing spiral surface 46 in contact with the shoulder of the dipstick whereby rotation of the dipstick and cam shoulder will cause the cam shoulder to ride along the spiral surface to translate the rotational movement of the dipstick and cam shoulder into axial reciprocating movement of the reciprocating assembly. A lower split ring 48 encircles the split cylinder at a lower extent.
The rotatable assembly is formed of an interior drum 50 above and an exterior drum 52 below and the upper shaft and the shaft. A radial bore 56, 58, 60, 24 extends through the interior drum and the exterior drum and the upper shaft and the dipstick. A cylindrical roll pin 62 extends through the radial bore to ensure concurrent rotational movement of all components of the rotatable assembly and to preclude relative axial movement between components of the rotatable assembly. The exterior drum is formed with an upper chamfer 64 and a lower chamfer 66. An upper split ring 68 encircles the split cylinder at a lower extent.
Next provided is a sealing assembly formed of an upper O-ring 72 and a lower O-ring 74. The upper O-ring is located between the upper chamfer and the interior drum. The lower O-ring is located between the lower chamfer and the sealing ring. In this manner, rotational motion of the rotational assembly will translate to axial raising of the reciprocating assembly to compress the O-rings and seal the component in the neck of an oil reservoir.
A repositionable cap 76 is next provided. The repositionable cap is positioned above the interior drum. The repositionable cap has a lower portion. The repositionable cap has a shiftable upper portion 82. A pivot pin 84 couples the upper and lower portions. An L-shaped leg 86 is formed in the upper portion to contact the detent during closing of the repositionable cap. A top O-ring 88 ensures sealing of the upper and lower portions.
An alternate embodiment of the invention is illustrated in FIGS. 14, 15 and 16. In this embodiment, the stick is an assembly 100 formed of a rigid dipstick 102 formed with a spherical upper end. A cage-like support 104 receives the spherical upper end. In this manner, the rigid dipstick always depends in a vertical orientation under the influence of gravity.
Another alternate embodiment of the invention is illustrated in FIGS. 17 and 18. In this embodiment, the stick is a flexible dipstick 108. In this manner, the flexible dipstick always depends in a vertical orientation under the influence of gravity.
The present invention is a chemical and heat resistant locking stopper component with a repositionable cap 76 for a bore such as a fill tube and having a length with wedges to expand rubber, rubber O-rings 72, 74 or soft metal C-rings or similar, and hard solid ring on the outside of the component. The stopper component is placed in the bore. The key 30 is inserted and the lock 28 turned. The lock is connected to a shaft 20 with a cam 22 located on the shaft. As the shaft turns the cam activates and sends upward pressure on the reciprocating external components 44, 40, 42. As upwards pressure is applied to the reciprocating external components. They compress rubber style O-ring components 72, 74 causing the O-rings to expand and create a better seal. They also cause a hard split ring 48 or similar style component to expand at the end extending beneath the bore or fill tube causing the locking stopper component to be larger at the bottom of the bore and not to be removed from the bore.
The component also has a retained cap 76 that either rotates out and back in place or uses a dove tail sliding type to cover and seal contaminants out of the lock and other parts of the stopper component.
As the key 30 is inserted, and rotated to remove the stopper component, the cam 22, 46 allows the parts 44, 40, 42 that traveled upwards to travel downwards and the rubber style component 72, 74 shrinks and the hard solid ring 48 or similar style shrinks and the stopper component can then be removed from the fill tube.
Elements 30, 28 are a key and a lock.
Element 38 is a spring that fits between the lock and the upper part of the upper shaft 32 to apply pressure to the mating parts of the upper shaft and the lock to create a seal with a soft metal washer 36 in place of a rubber seal.

Element 80 is a soft component such as O-rings under the cap that would allow the stopper component to set on the fill tube of an oil reservoir.
Element 50 is the interior drum.
A tapered ledge is formed in an upper region of the interior tube 50. A round O-ring 72 limits movement of the sealing cylinder 42 and elements above the sealing cylinder.
Surfaces on the shoulder 22 and cam cylinder 44 act to force the split cylinder 40 apart with the upward movement of the split cylinder. The lower end of interior drum is tapered to spread and separate the split cylinder 40.
O-ring 72 is a sealing component, an O-ring with a wedge behind in the upper area.
Element 56 is a bore for use during assembly.
Element 52 is the exterior drum with wedges on top and bottom that mate with O-rings or expanding sealing device so that when pressure is applied, and parts are axially forced together whereby the sealing devices expand and provide a better seal in the fill tube.
Element 42 is a sealing cylinder, another sliding device that has a wedge and a sealing device installed as an O-ring that mates with the exterior drum.
Element 40 is a split cylinder that fits partially inside the sealing cylinder when forced upwardly to a tapered diameter that will not let it be removed from the fill tube.
Element 48 on the split cylinder is a split ring 48 to collapse parts together when there is no pressure forcing the parts upwardly.
Element 44 is a cam cylinder with a male type slot or square that keeps this part from turning and allows the parts to travel upwards to force the parts together.
The upper extent of the cam cylinder 44 is a cam system that forces parts upwards when the other portion of the cam is rotated.
