DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

[0059] For a more complete understanding of the present invention, reference is now made to the following description of various illustrative and non-limiting embodiments thereof, taken in conjunction with the accompanying drawings in which like reference numbers indicate like features.

[0060] Addressing one or more of the above-described drawbacks or needs in the prior art (or other drawbacks or needs not specifically described herein), at least one embodiment of the subject invention comprises a grinding apparatus capable of grinding material, such as tobacco or other smokeable material, and selectively delivering desirable amounts of such ground material to chosen or selected receptacle volumes. In some embodiments, the ground material may also be delivered to a storage area or chamber, when desired, for later access or use by the device operator.

[0061] Referring now to FIGS. 1-10, a non-limiting, example embodiment of such a grinder apparatus 1 is illustrated therein. Grinder apparatus 1, as illustrated, generally comprises at least three main components (preferably detachable from one another), including a grinding mechanism 3 sitting on top of an intermediate body 4, which in turn is connected to a top portion of receptacle body 9. Optionally, a storage chamber body 16 is also provided, attached at or to a bottom portion of receptacle body 9, in embodiments which include storage (e.g., as opposed to receptacle loading) functionalities. While FIG. 1, for example, illustrates a grinder apparatus having various parts, such as the external wall of receptacle body 9, as translucent or transparent, other embodiments utilize (partially or fully) opaque walls or parts (see, e.g., FIG. 2). The inclusion of translucent or transparent parts is largely for ornamental purposes, but may at times offer certain benefits to device functionality. For example, in embodiments which employ translucent or transparent parts, it is possible to see when chambers or receptacle volumes contain ground material (or when they contain smoking or rolling papers or cones).

[0062] Grinding mechanism 3, as illustrated in FIG. 5, is preferably but not necessarily at least a two-part mechanism which may be opened, as depicted in the drawings, to insert or load grindable material such as tobacco. Once tobacco, or a similar substance, is loaded into the grinding mechanism, the upper and lower halves of mechanism 3 are assembled to one another, such that they are rotatable one with respect to the other. When rotated as such, upper and lower “teeth” 3a and 3b act in concert with each other (e.g., move past each other, with the inserted tobacco forced or pushed between the upper and lower teeth) to break-up, macerate, and/or grind the inserted tobacco into smaller, preferably fine bits or portions which are more easily burned for smoking. Of course, while the illustrated grinding mechanism 3 works well with apparatus 1, and includes knurled grip portions 3c for providing a reliable gripping surface when hand grinding tobacco, other grinder mechanism types may be used with the present invention. For example, a hand crank and/or one or more motors may be provided to assist with grinding operations. Moreover, banks of teeth 3a and 3b may be replaced with other grinder elements such as cutting blades or crushing elements.

[0063] Once the inserted tobacco (or any other substance added to the device to be ground) is processed in grinder mechanism 3, the smaller, fine tobacco particles which are obtained during a grinding operation are small enough to pass through grinder apertures 2, through which they exit grinder mechanism 3 and enter intermediate chamber 5. Intermediate chamber 5, as seen for example in FIGS. 7A-7C, is formed in intermediate body 4 and includes an intermediate chamber aperture 7. Chamber 5 is primarily utilized to “catch” ground material, after it is ground in grinder mechanism 3, and then to deliver the ground material to one or more receptacle volumes, or to a storage delivery volume. In this regard, intermediate body 4 is rotatable about central axis 15 (see, e.g., FIGS. 1-2) so as to be able to align chamber aperture 7 with a selected receptacle volume or a storage delivery volume (as described more fully below). Chamber 5 preferably (but not necessarily) includes a sloped or angled “floor” or bottom surface 8 which is included and angled and/or otherwise configured to direct the flow of “caught” ground material to and towards intermediate chamber aperture 7.

[0064] In preferred embodiments, chamber aperture 7 has a diameter or opening size which is a fraction of the surface area of the floor or bottom surface of intermediate chamber 5. In particularly preferred (but still optional) embodiments, the aperture opening size is a size selected from between approximately 1/20th to ¼ of the surface area of the chamber's floor or bottom surface. In particular, such a sized opening is selected so that a metered or otherwise limited or controlled amount or rate of ground material may be delivered by the chamber aperture 7 to a specifically selected volume of receptacle body 9. In the most preferred embodiments, aperture 7 opening is so sized and positioned such that it is similar to or closely matched to the size of upper receptacle volume apertures or openings within receptacle body 9. In such or other preferred (but still optional) embodiments, intermediate body 4 is rotatable relative to receptacle body 9 (either by detaching and rotating the body before reinstalling, or by rotating the body as assembled, such as about the axis of a centrally installed center pin) in order to match or align the location of chamber aperture 7 with a desired receptacle volume (e.g., one of volumes 11a-11f) of receptacle body 9. More specifically, by selectively aligning chamber aperture 7 with a chosen receptacle volume 11a-11f, ground material, such as ground tobacco, may be delivered directly from intermediate chamber 5 to the selected aperture volume (e.g., selected from volume 11a-11f).

[0065] In certain embodiments, in order to aid with alignment of chamber aperture 7 with a selected aperture volume 11a-11f and/or as an aid to maintaining such alignment, magnetic and/or magnetic/ferrous paired elements may be included at select locations on apparatus 1. More specifically, in the non-limiting example embodiments illustrated in FIGS. 7D and 8, magnets 25 and ferrous elements 27 are included positioned or located near or adjacent to receptacle volume apertures 11a-11f (see FIG. 8) and near or adjacent to chamber aperture 7 (see FIG. 7D). By including magnets and ferrous elements located as illustrated, when two magnets, as a defined pair, are aligned with two ferrous elements, as a defined pair, alignment of chamber aperture 7 with one of the six illustrated receptacle volumes 11a-11f is ensured. Moreover, because of the magnetic attraction of the magnets to the ferrous elements, the alignment of chamber aperture 7 to the selected receptacle volume is maintained until a sufficient, intentional “breaking force” is applied to break the magnetic attraction of the magnets/ferrous element pairs. Of course, instead of utilizing ferrous elements paired with magnets, magnets of opposite polarities may also be used to for the benefit of their attractive magnetic force to the opposing magnet of opposite polarity. Maintaining such alignment, of course, ensures that when ground material, such as ground tobacco, exits chamber aperture 7, the ground material is successfully delivered to a chosen or selected receptacle volume (e.g., one of volumes 11a-11f). Additional aids to alignment, or to maintaining alignment, such as mechanical piece interlocks may also be employed (alone or in combination with magnetic elements).

[0066] During operation of grinder apparatus 1, once tobacco or another material is loaded into the grinding chamber (i.e., the inner volume of grinder mechanism 3), a device user can select where, within the device, he/she wishes the resulting ground material to be delivered. For example, in the non-limiting embodiment of the invention, which is illustrated, there are six different receptacle volumes housed within receptacle body 9. Five of these volumes, in the illustrated embodiment, are conical in configuration (see volumes 11a-11e) and are preferably (but not necessarily) provided with visual markings (e.g., Arabic or Roman numerals), so that the volume identity may be readily visually ascertained. Of course, other markings may be used to identify a volume, such as Braille-type markings, or no markings included at all. The sixth depicted volume, illustrated in the example embodiment as volume 11f (marked with the letter “E” in the drawings), is, however, not conical in configuration but instead comprises a simple cylinder with an open, rather than closed bottom. Employing the illustrated volume configurations, a user can load smoking paper, rolled into a conical configuration, into one or more of volumes 11a-11e prior to a grinding operation. Once loaded as such, a user of the device can choose to deliver ground material (such as ground tobacco) directly into a desired volume containing pre-loaded smoking paper. In this manner, a more efficient method of assembling custom smoking “cigarettes” is accomplished. Conversely, if the device user does not wish to assemble a “cigarette”, or if there is excess ground material, the device user can select volume 11f as a delivery location, so that the ground tobacco or other material passes into the cylinder of volume 11f and then from the cylinder into storage chamber 17 of storage body 16. Selection of a delivery location for ground material is accomplished, of course, by simply rotating receptacle body 9 relative to intermediate body 4 to align chamber aperture 7 with the desired receptacle volume 11a-11f.

[0067] When utilizing grinding apparatus 1 to assemble custom cigarette-type smoking products, it may be desirable to tamp down or pack ground material into pre-loaded wrapping papers. Therefore, in certain optional embodiments, a tamping rod 29 is preferably included with the apparatus which may optionally be stored in aperture 28 located near or at the central axis of receptacle body 9. Other storage locations may of course be provided.

[0068] Note, while six receptacle volumes are illustrated and described in the present application, other numbers and configurations of receptacle volumes may be employed without departing from the scope of the subject invention. Moreover, the use of magnets/ferrous elements (or magnets of opposite polarity) to align chamber aperture 7 with a receptacle volume is optional, and alternative alignment mechanisms may, of course, be employed, or alignment aids may be eliminated all together.

[0069] In an alternative embodiment of a grinder apparatus disclosed in FIGS. 11-28, illustrated as grinder apparatus 101, additional utilitarian advantages are provided. For example, as shown in these figures, mechanically operated risers (or “elevators”) 51 (see FIG. 23) are provided, which can be operated to lift already filled cones within their installed receptacles. This is so that the cones can be more conveniently and easily accessed and removed by a human user operating the apparatus. Apparatus 101, in this regard, is otherwise illustrated in these figures using like part numbers for like or similar features, but with a “′” symbol added to the common (or similar) part number(s) to distinguish apparatus 101 parts from the parts of grinder apparatus 1. For example, the grinder portion of apparatus 1 is labelled with number “3” but the grinder portion of grinder apparatus 101 is labeled 3′.

[0070] As illustrated in these figures, and with particular initial focus on FIG. 23, both inner and outer lift rings 53 and 55, respectively, are provided in this embodiment (as a lift ring assembly) joined together by connecting arm structures 57 which extend vertically (to space the inner and outer rings vertically apart) and which pass through one or more slot-like apertures 57 in the cylindrical shell of the apparatus so that the outer ring can be articulated upwards and downwards while remaining connected to the inner ring. When articulated up and down, because the outer ring 55 is connected to the inner ring 53 with the connecting arm structures 57, the inner ring 53 is also articulated upwards and downwards. Furthermore, the inner ring is outfitted with an array of vertical lifting rods 51 (or elevators) each of which are mechanically connected within the circumference of the inner ring. Such vertical lifting rods 51 are optimally spatially arranged so that each rods aligns with an independent receptacle volume (one of 11a′-11f′) so that the aligned rod can be moved upwards or downwards within the receptacle volume. Configured as such, when the plurality of receptacle volumes are pre-loaded with a plurality of cones, and the grinder is operated to fill such cones as described in the specification above, the cones can thereafter be lifted up within the receptacles using the lift ring structure accessible on the exterior of the grinder apparatus. That is, by manually mechanically raising the exterior lift ring structure 55, the inner ring 53 is also lifted (because it is connected to the exterior ring), as are the vertical lifting rods 51, each located below a cone within a respective receptacle. Accordingly, when the exterior lift ring structure is raised, the vertical lifting rods 51 each engage the bottom of a cone within their respective receptacle and raise the cone within the receptacle a distance which is commensurate with the raise distance of the exterior ring 55. Once raised as such, and with the grinder 3′ and intermediate body removed 4′, the cones are more easily accessed by a device user so that the upper portion of the cone may be physically grasped by a user so that it can be further lifted and ultimately removed from the respective receptacle. This feature is a significant advantage because it allows cones to be removed, while leaving the cones in a vertical orientation, so that ground material stored (or packaged) within the cones does not fall out of the top open end.

[0071] The specific lift ring assembly embodiment illustrated is particularly advantageous, but other physical and/or mechanical configurations for accomplishing the same functions are contemplated.

[0072] As a further advantage to the lift (or lifter) ring assembly, the outer ring 55 can be mechanically oscillated up and down rapidly manually by an apparatus user. If this is done when cones installed in the receptacle body are already filled, the up/down oscillating motion will cause the installed cones to move up/down (through their contact with the vertical lifting rods 51), and/or the vertical lifting rods 51 will repeatedly and rapidly tap the bottom of the cones to serve to pack ground material more densely into the cones. Alternatively, an automated oscillating or vibrating mechanism (e.g., 63 or 66 in FIG. 13) may be included with the device. For example, a vibration inducing mechanism (e.g., battery operated) can be installed connected to receptacle body 9′ (as unit 63 with switch 65), or even communicably connected to the inner lift ring so that, when it is operated to vibrate, the inner lift ring imparts vibration to the vertical lift rods which, in turn, impart vibration to the installed cones. This will also serve to pack the ground material more densely in the cones. In still another embodiment, an oscillating plate (or similar mechanical mechanism) can be installed below the inner lift ring so that when it is turned on (e.g. being a battery operated device), the inner lift ring is rapidly moved upwards or downwards by the oscillating plate to also serve to pack the ground material more densely in the cones. Afterwards, an optional tamping rod 61—which can be stored in an aperture 28′ located proximal the middle of the receptacles—can be removed and used to manually “tamp” or pack the ground material even more densely into the cones.

[0073] In still another embodiment, a vibrating device 66 can be utilized installed in communication with the intermediate body so that, when operated (e.g., as a battery powered device with a switch 67), the vibration imparted to the intermediate body (e.g., the sloped or ramped surface 8′ of the intermediate body 4′) aids in moving or delivering ground material from the intermediate body, down the optional sloped surface towards the aperture provided for delivering ground material to the receptacles located in the receptacle body mounted below.

[0074] As illustrated in FIGS. 21 and 27, this particular embodiment also includes improvements to the grinder mechanism. For example, the shape and arrangement of the grinder teeth 71 (e.g., as “diamond” shaped) has proven advantageous during operation of the grinding mechanisms. Furthermore, the peaks 73 repeatedly disposed along the inner circumferential wall of the lower grinder body half help immobilize material loaded into the grinder 3′ so that when the grinder is operated (e.g., by rotating the upper half of the grinder back and forth relative to the lower grinder body half), the grinder teeth are able to grind or macerate the material (e.g., tobacco) more efficiently and/or thoroughly. This is because the material is more effectively immobilized (i.e., held in place, instead of moved around) against the action of the grinder teeth. As yet an additional option, filter 77 (see FIG. 21) can be installed between the grinding mechanism and intermediate body 4′ so that only the desired size of material particles are delivered to the receptacles.

[0075] Once given the above disclosure, many other features, modifications, and improvements will become apparent to the skilled artisan. Such features, modifications, and improvements are therefore considered to be part of this invention, without limitation imposed by the example embodiments described herein. Moreover, any word, term, phrase, feature, example, embodiment, or part or combination thereof, as used to describe or exemplify embodiments herein, unless unequivocally set forth as expressly uniquely defined or otherwise unequivocally set forth as limiting, is not intended to impart a narrowing scope to the invention in contravention of the ordinary meaning of the claim terms by which the scope of the patent property rights shall otherwise be determined.
