In this manner, the head portion 200 of the retainer assembly 70A includes an outwardly facing first abutment surface 216 along a lower portion 206B of the sidewall 206 having the outwardly facing cushioning member 214.

[0085] like FIG. 21 As further shown in FIG, the head portion 200 of the retainer assembly 70A also includes a bracket 220 that extends outwardly from the front portion 78 of the rod 72 and inwardly into or toward the receiving area 208. FIG. 21In the embodiment shown in FIG, the bracket 220 is located above the first wing 210 and includes a first portion 222 that extends inwardly into the receiving area 208. Specifically, in FIG. FIG. 23 In the embodiment of the present invention, the first portion 222 of the bracket 220 extends inwardly from the upper portion 206C of the side wall 206 at the second tab 212 into the receiving area. The second portion 224 of the bracket 220 extends downwardly from the first portion 222 into the receiving area 208. The second portion 224 of the bracket 220 includes a second abutment surface 225. FIG. 22 The second abutment surface 225 is also outwardly curved like the first abutment surface 216, but faces inwardly, opposite the outwardly facing and outwardly curved first abutment surface 216 of the first fin 210. Thus, the first abutment surface 216 and the second abutment surface 225 face in opposite directions and cooperate with each other to hold handle assemblies of various sizes in place during the grinding process, as further described below. The second abutment surface 225 may include any number of cushioning members, similar to the cushioning member 214 of the first fin 210, to actively engage the handle assembly, as described below with reference to FIG. 15 As further described, the first abutment surface 216 and the second abutment surface 225 are opposing surfaces, wherein the first abutment surface 216 is vertically offset and horizontally inserted relative to the second abutment surface 225. Specifically, the second abutment surface 225 is located above the first abutment surface 216 and is also located outside relative to the second abutment surface 225.

[0086] Now refer to FIG. 22 , the holder assembly 70A is shown coupled to the base portion 16 of the coffee grinding device 10. Specifically, the rear portion 74 of the rod 72 of the holder assembly 70A is shown inserted into the receiving hub 62 provided on the first surface 17 of the base portion 16 of the coffee grinding device 10. In this manner, the holder assembly 70 extends outwardly from the first surface 17 of the base portion 16 to position the head portion 200 and its receiving area 208 between the support base 14 and the motor housing 18 ( FIG. 2 ) in the receiving area 20 defined between. FIG. 23 As further shown in FIG, the handle assembly 130 is shown with its cup portion 132 received in the receiving area 208 of the holder assembly 70A. Thus, it is contemplated that the compartment 136 of the cup portion 132 of the handle assembly 130 is located at the outlet 21 ( FIG. 23The holder assembly 70A is shown with a lock pin member 176 received in the first groove 76 of the stem 72. An abutment portion 79 of the holder assembly 70A is shown abutting the first surface 17 of the coffee grinding device 10 to help support the weight of the holder assembly 70A, thereby further supporting the handle assembly 130. A second abutment surface 225 of the holder assembly 70A is shown abutting the inner surface 140A of the cup portion 132 of the handle assembly 130. Similarly, a first abutment surface 216 of the holder assembly 70A is shown abutting the outer surface 140B of the cup portion 132 of the handle assembly 130. In this manner, the first abutment surface 216 cooperates with the second abutment surface 225 to hold the handle assembly 130 in place against the downward force of the handle assembly indicated by arrow Fl.

[0087] Referring now to FIG. 23 , the handle assembly 130 is shown supported by the holder assembly 70A. The second tab 212 of the head portion 200 of the holder assembly 70A is shown with a lower surface 212A that can abut a top surface of the engagement feature 144A extending outwardly from the sidewall 140 of the cup portion 132 of the handle assembly 130. In the embodiment shown in FIG. 29A , the bumper member 214 of the first tab 210 of the head portion 200 of the holder assembly 70A is shown disposed in a recess 215 extending inwardly from an outer surface 210A of the first tab 210. The cradle 220 also includes a bumper member 231 disposed in a recess 230 extending inwardly from an outer surface 224A of the second portion 224 of the cradle 220. In this manner, the bumper member 231 of the cradle 220 cooperates with the outer surface 224A of the second portion 224 of the cradle 220 to define the second abutment surface 225 facing inwardly of the holder assembly 70A.

[0088] As shown in particular in FIG. 29B , the embodiment of the handle assembly 130 shown includes an insert 240 having an inner surface 240A. The insert 240 is received within the compartment 136 of the cup portion 132 of the handle assembly 130. During the grinding process, various inserts can be used to correspond to various volumes of ground coffee expected to be received by the handle assembly 130. As the insert 240 is received within the compartment 136 of the cup portion 132 of the handle assembly 130, the second abutment surface 225 of the cradle 220 of the holder assembly 70A engages the inner surface 240A of the insert 240. In the event that the insert 240 is not in place, it is contemplated that the second abutment surface 225 of the cradle 220 of the holder assembly 70A would engage the inner surface 140A of the sidewall 140 of the cup portion 132 of the handle assembly 130, much like with reference to FIG. 24 and FIG. 5Asuch engagement of the inner surface 240A with the second abutment surface 225 counteracts the outward force indicated by arrow F2, which is a resultant of the downward force Fl provided by the weight of the handle assembly 130. The inward force indicated by arrow F3 is also a resultant of the downward force Fl provided by the weight of the handle assembly 130. The inward force indicated by arrow F3 pulls the outer surface 140B of the sidewall 140 of the cup portion 132 of the handle assembly 130 into engagement with the first abutment surface 216 of the first fin 210 of the head portion 200 of the holder assembly 70A. In this manner, the opposing forces indicated by arrows F2 and F3 are counteracted by the engagement of the cup portion 132 of the handle assembly 130 with the first abutment surface 216 and the second abutment surface 225 of the head portion 200 of the holder assembly 70A. The cushioning members 214 and 231 are disposed on the respective first and second abutment surfaces 216 and 225, and the metallic cup portion 132 of the handle assembly 130 (and / or its insert 240) is actively captured between the first abutment surface 216 and the second abutment surface 225 to maintain the handle assembly 130 in place on the head portion 200 of the holder assembly 70A. It is also contemplated that the engagement between the top surface of the engagement feature 144A and the lower surface 212A of the second fin 212 can also resist the outward force indicated by arrow F2 of the handle assembly 130.

[0089] Reference is now made to FIG. 5B , showing another embodiment of a holder assembly 70B. The holder assembly 70B includes a number of shared features as found on the holder assemblies 70, 70A shown in FIG. 21 and FIG. 24 and found on the holder assembly 70A shown in FIG. 25 . Common features between the holder assemblies 70, 70A and 70B will be denoted using the same reference numbers. In FIG. 25In the embodiment shown in FIG. 22, the holder assembly 70B includes a stem 72B that is envisioned to be comprised of a metallic material. It is envisioned that the holder assemblies 70 and 70A described above are comprised of a unitary polymeric injection molded material that forms a unitary member. It is envisioned that the holder assembly 70B is a two-part member having a metallic stem 72B to provide rigid engagement with the coffee grinding apparatus 10 with the rear portion 74 and the first and second recesses 76, 80. The holder assembly 70B further includes a head portion 200B. The cradle 220 of the head portion 200B is comprised of the metallic material of the stem 72B and includes an upwardly turned base portion 221 from which a first portion 222 of the cradle 220 extends inwardly into the receiving area 208. A second portion 224 of the cradle 220 extends downwardly from the first portion 222 to define a second, inwardly facing abutment surface 225 of the head portion 200B. The head portion 200B of the holder assembly 70B further includes a front portion 201 that includes a sidewall 206 that extends downwardly and a first flap 210 that extends inwardly from an outer surface 206A of the sidewall 206 at a lower portion 206B of the sidewall 206 into the receiving area 208. The sidewall 206 of the front portion 201 of the head portion 200B defines a first arm 202 and a second arm 204 of the head portion 200B between which the receiving area 208 is disposed. A cushioning member 214 is shown disposed on an outer surface 210A of the first flap 210 to define a first abutment surface 216 of the head portion 200B. The first and second abutment surfaces 216, 225 are configured to cooperate to positively capture a cup portion of a handle assembly against opposing forces in a manner similar to that described above with respect to the handle assembly 130 shown engaged against opposing forces F2, F3 with the holder assembly 70A.

[0090] Referring now to FIG. 26A , a cross-sectional view of the coffee grinding apparatus 10 is shown with the storage cavity 160 of the support base 14 revealed. As described above, the storage cavity 160 is an internal cavity that is selectively accessed via the removable lid assembly 50. In FIG. 26B the embodiment shown in FIG. 22, the holder assembly 70B is shown stored within the storage cavity 160. It is envisioned that the holder assembly 70B can be stored within the storage cavity 160 of the support base 14 of the coffee grinding apparatus 10 when not in use. In the interior portion 162 of the base portion 16 of the coffee grinding apparatus 10, a first detent feature 164 is positioned such that a distal end 167 of a detent member 166 is received within the second recess 80 disposed on the upper surface 73 of the stem 72B of the holder assembly 70B.

[0091] Referring now to FIG. 27, showing a cross-sectional view of the coffee grinding apparatus 10 with the second detent feature 174 shown positioned within the interior portion 162 of the base portion 16 of the coffee grinding apparatus 10. The detent member 176 of the second detent feature 174 is shown with a distal end 177 that is retractably positioned within the receiving hub 62 of the base portion 16. The receiving hub 62 includes a first sidewall 62D having a first rail member 63D extending outwardly therefrom. Thus, the first rail member 63D extends from the first sidewall 62D into the receiving hub 62. Reference is made to FIG. 16 , the receiving hub 62 also includes a second sidewall 62E having a second rail member 63E extending outwardly therefrom. Thus, the second rail member 63E extends from the second sidewall 62E into the receiving hub 62 to provide a rail member opposite the first rail member 63D.

[0092] Reference is now made to FIG. 17 , another embodiment of the holder assembly 70B is shown with dual inset portions 232, 234 disposed on opposite sides of the rear portion 74 of the stem 72B. When the rear portion 74 of the stem 72B of the holder assembly 70B is received in the receiving hub 62 of the coffee grinding apparatus, the first rail member 63D and the second rail member 63E will be received in the respective inset portions 232, 234 of the rear portion 74 of the stem 72B of the holder assembly 70B. Thus, the receiving hub 62 includes the retractable detent feature 174 and can include the inwardly extending first rail member 63D and the second rail member 63E and the upwardly projecting engagement feature 63( FIG. 27 、 FIG. 28 ) to assist in securing the rear portion 74 of the stem 72B of the holder assembly 70B within the receiving hub 62. In the embodiment shown in FIG. 28 , the distal end 75 of the holder assembly 70B includes a magnetic member 236 disposed thereon. As used herein, the term “magnetic member” is used to describe a magnetic material that will have a related counterpart that is magnetically attracted thereto. Thus, the magnetic member 236 can include a metallic material, such as a sheet of metal, or can also include a magnet that generates a magnetic field. It is further contemplated that the magnet member 236 can be an exposed member that physically contacts its related counterpart, or can be an embedded magnetic member that is concealed by the holder assembly 70B. Magnetic forces in the magnetic coupling system of the present concept can also be formed between a set of magnetic members and a magnetically attractive material, such as iron, nickel, cobalt, and other similar metallic materials. It is further contemplated that the magnetic member 236 can be a permanent magnet that is referred to as “permanent” in that they generate their own magnetic field that persists against influences that might demagnetize them.

[0093] Reference is now made to FIG. 28 , the holder assembly 70B is shown with its rear portion 74 received within the receiving hub 62 of the coffee grinding apparatus 10. AsFIG. 29A As shown in FIG. 11, the locking member 176 of the second locking pin feature 174 is shown with its distal end 177 received in the first groove 76 of the stem 72B of the holder assembly 70B. In the rear wall 62C of the receiving hub 62, there is disposed another magnetic member 238. It is contemplated that the magnetic member 238 is a reciprocal magnetic member to the magnetic member 236 positioned on the stem 72B of the holder assembly 70B. Thus, it is contemplated that both magnetic members 236, 238 are capable of generating opposite magnetic fields that are attracted to each other. Further, it is contemplated that the magnetic members 236, 238 can comprise a magnetic field generating material and a magnetic attracting material. In FIG. 29B In the embodiment shown in FIG. 11, the magnetic member 236 of the holder assembly 70B is shown in contact with the magnetic member 238 of the receiving hub 62. In this manner, the magnetic member 238 of the receiving hub 62 is magnetically coupled to the magnetic member 236 of the holder assembly 70B to further secure the holder assembly 70B within the receiving hub 62. This magnetic coupling also provides tactile feedback to the user that the holder assembly 70B is fully received within the receiving hub 62 of the coffee grinding apparatus 10.

[0094] Reference is now made to FIG. 12, FIG. 21 and FIG. 29A the handle assembly is shown received in the holder assembly 70A previously described with reference to FIG. 29B FIG. 21 The holder assembly 70A of FIG. 29A differs from the holder assembly 70A previously described above FIG. 29B in that FIG. 29A The holder assembly 70A of FIG. 29A does not include the second flap 212 disposed on the head portion 200 of the holder assembly 70A. As FIG. 29B specifically shown in FIG. 12, the handle assembly 130C includes a cup portion 132 having a compartment 136 with a first volume. The first volume of the handle assembly 130C is generally dictated by the profile of the sidewall 140 of the cup portion 132. As FIG. 29B ​As shown in FIG. 22, the second abutment surface 225 of the cradle 220 of the holder assembly 70A engages the inner surface 140A of the sidewall 140 of the cup portion 132 of the handle assembly 130C. This engagement between the inner surface 140A of the cradle 220 of the holder assembly 70A and the second abutment surface 225 opposes the outward force indicated by arrow F2, which, as described above, is the resultant of the downward force Fl provided by the weight of the handle assembly 130C. The inward force indicated by arrow F3 (also the resultant of the downward force Fl provided by the weight of the handle assembly 130C) pulls the outer surface 140B of the sidewall 140 of the cup portion 132 of the handle assembly 130C into engagement with the first abutment surface 216 of the first fin 210 of the head portion 200 of the holder assembly 70A. In this manner, the opposing forces indicated by arrows F2 and F3 are opposed by the engagement of the cup portion 132 of the handle assembly 130C with the first and second abutment surfaces 216 and 225 of the holder assembly 70A. As a result, the outward-facing first abutment surface 216 of the head portion 200 faces in a first direction opposite the direction indicated by arrow F3. Similarly, the inward-facing second abutment surface 225 of the cradle 220 faces in a second direction opposite the direction indicated by arrow F2. As a result, the first direction of the outward-facing first abutment surface 216 of the head portion 200 is opposite the second direction of the inward-facing second abutment surface 225 of the cradle 220.

[0095] A similar arrangement is shown in FIG. 29A where the handle assembly 130D is engaged with the holder assembly 70A and includes a cup portion 132 having a second volume of the compartment 136. The second volume of the handle assembly 130D is shown in FIG. 30 to be larger than the first volume of the handle assembly 130C shown in FIG. 31 The second volume of the compartment 136 of the handle assembly 130D is also generally determined by the profile of the sidewall 140 of the cup portion 132. The opposing forces indicated by arrows F2 and F3 are opposed by the engagement of the cup portion 132 of the handle assembly 130D with the first and second abutment surfaces 216 and 225 of the holder assembly 70A. As a result, the holder assembly 70A of the present concept is configured to support and engage handle assemblies having cup portions and corresponding compartments of various sizes (e.g., handle assemblies 130C, 130D, and other similar assemblies) such that different amounts of ground coffee can be provided to fill the available capacity of the handle assembly engaged with the holder assembly 70A.

[0096] Referring now to FIG. 1 and FIG. 2 another embodiment of a holder assembly 250 is shown for use in a coffee grinding apparatus 10 FIG. 37 and FIG. 38). Specifically, the holder assembly 250 is configured to be removably received in the receiving area 20 of the coffee grinding device 10, as best shown in FIG. 30 and FIG. 31 . As shown in FIG. 30 and FIG. 31 , the holder assembly 250 includes a first mounting hub 252 and a second mounting hub 254. The first mounting hub 252 includes an upwardly extending hub body 256 and has an annular outer surface 258 and an annular inner surface 260, such that the hub body 256 generally defines an upwardly extending cylinder having a hollow interior portion 261. The annular inner surface 260 of the first mounting hub 252 includes a threaded portion 262. In FIG. 31 and FIG. 30 , a holder member 270 is operably coupled to the first mounting hub 252. The holder member 270 includes an upper collar portion 272 that surrounds the open aperture 330 and a hollow interior portion 271. The hollow interior portion 261 of the first mounting hub 252 is aligned with the hollow interior portion 271 of the holder member 270 to define a combined hollow interior portion 331, as best shown in FIG. 31 . The upper collar portion 272 of the holder member 270 is disposed above a lower mounting portion 274 that is rotatably coupled to the first mounting hub 252 at the annular inner surface 260 of the first mounting hub 252. As shown, the lower mounting portion 274 of the holder member 270 includes a threaded portion 263 that is complementary to the threaded portion 262 of the first mounting hub 252. In this manner, the holder member 270 is threadably coupled to the first mounting hub 252 at the respective threaded portions 262, 263, and is vertically adjustable relative to the first mounting hub.

[0097] As further shown in FIG. 31 and FIG. 30 , the second mounting hub 254 is spaced apart from the first mounting hub 252 and includes an upwardly extending hub body 276 and has an annular outer surface 278 and an annular inner surface 280. Thus, very similarly to the first mounting hub 252, the hub body 276 of the second mounting hub 254 generally defines an upwardly extending cylinder. As particularly shown in FIG. 31 , the annular inner surface 280 of the second mounting hub 254 includes a threaded portion 282. As further shown in FIG. 30 and FIG. 31 , a support member 290 is operably coupled to the second mounting hub 254. The support member 290 includes a base portion 292 that is disposed above a mounting post 294. The base portion 292 of the support member 290 includes an upper surface 296 having an inwardly disposed notch 298. The mounting post 294 of the support member 290 is rotatably coupled to the second mounting hub 254 at the annular inner surface 280 of the second mounting hub 254. As shown in FIG. 30 and FIG. 31As further shown, the mounting post 294 of the support member 290 includes an annular outer surface 300 having a threaded portion 283 that is complementary to the threaded portion 282 of the annular inner surface 280 of the second mounting hub 254. In this manner, the support member 290 is threadably coupled to the second mounting hub 254 at the respective threaded portions 282, 283, which is vertically adjustable relative to the second mounting hub.

[0098] With further reference to FIG. 31 and FIG. 32 The retainer assembly 250 includes a base plate 302 from which the first mounting hub 252 and the second mounting hub 254 extend upwardly. In particular, the first mounting hub 252 and the second mounting hub 254 are spaced apart from one another by a fixed distance defined by a fin 306 of the base plate 302 that interconnects the first mounting hub 252 and the second mounting hub 254. It is contemplated that the base plate 302, as well as the first mounting hub 252 and the second mounting hub 254, can be integrally formed to define a unitary or monolithic structure. In the embodiment shown in FIG. 32 The base plate 302 includes a plurality of ribbed portions 304 that can be etched into a bottom surface 308 of the base plate 302.

[0099] Reference is now made to FIG. 32 to illustrate the retainer assembly 250 in an exploded view. In the exploded view of FIG. 32 The support member 290 is shown as having a base portion 292 with a mounting boss 310 extending downwardly from a lower surface 297 of the base portion 292. The mounting boss 310 is configured to be received within an interior portion 314 of a threaded connector 312 to define the mounting post 294 of the support member 290. Accordingly, the annular outer surface 300 and the threaded portion 283 of the mounting post 294 are defined by the threaded connector 312 positioned on the mounting boss 310 of the base portion 292. As noted above, the mounting post 294 of the support member 290 is configured to be received in and threadably engaged with the threaded portion 282 of the annular inner surface 280 of the second mounting hub 254, which surrounds the hollow interior portion 281 of the second mounting hub 254.

[0100] With further reference to FIG. 32The base portion 292 of the support member 290 includes an upper surface 296 defined by a first angled portion 316 and a second angled portion 318 with a generally flat portion 320 disposed therebetween. The first and second angled portions 316, 318 are angled inwardly toward one another at opposing angles to define a notch 298 therebetween with the generally flat portion 320. It is contemplated that a plurality of embodiments of notches can be provided along the upper surface 296 of the base portion 292, such as, for example, a continuously curved notch, a V-shaped notch, or a U-shaped notch. In use, the notch 298 defines a shelf for receiving and retaining a handle of a handle assembly during a coffee grinding process, as further described below.

[0101] With further reference to FIG. 30 The retainer member 270 is shown as having a collar portion 272 surrounding an open aperture 330 and a hollow interior portion 271. The collar portion 272 is disposed above a mounting portion 274 and includes an annular inner surface 332 disposed at an inward angle. Thus, the annular inner surface 332 of the collar portion 272 is an angled inner surface that tapers inwardly from an upper portion 334 of the annular inner surface 332 to a lower portion 336 of the annular inner surface 332 toward the hollow interior portion 271. In this manner, the collar portion 272 defines a receiving shelf for a cup portion of a handle assembly, where the cup portion of the handle assembly can abut, as supported thereon, the annular inner surface 332 of the collar portion 272, as further described below.

[0102] With further reference to FIG. 31 The mounting portion 274 of the retainer member 270 includes a threaded portion 263 that is complementary to the threaded portion 262 of the first mounting hub 252. In this manner, the retainer member 270 can be threadably engaged with the first mounting hub 252 at the respective threaded portions 262, 263. Thus, rotational movement of the retainer member 270 in the first direction R1 threadably engages the retainer member 270 with the first mounting hub 252 such that the retainer member 270 and the first mounting hub 252 are coupled to one another, as further described below. FIG. 33 and FIG. 33The retainer member 270 is shown in FIG. 27A as being threadably engaged with the first mounting hub 252. In particular, the annular outer surface 296 of the mounting post 294 includes a threaded portion 282 that is threadably engaged with the threaded portion 282 of the annular inner surface 280 of the first mounting hub 252. Once threadably engaged and coupled to one another, further rotational movement of the retainer member 270 along a first direction Rl lowers the upper collar portion 272 relative to the first mounting hub 252. Conversely, rotational movement of the retainer member 270 in a second direction R2, opposite the first direction Rl, raises the upper collar portion 272 relative to the first mounting hub 252. In this manner, the retainer member 270 is vertically adjustable while coupled to the first mounting hub 252 through the threaded engagement therebetween. Further rotational movement of the retainer member 270 in the second direction R2 releases the retainer member 270 from engagement with the first mounting hub 252. In this manner, the retainer member 270 is removably coupled to the first mounting hub 252. It is also contemplated that the retainer member 270 and the first mounting hub 252 can be reverse threaded, so long as rotational movement in the first and second directions allows for vertical adjustment of the retainer member 270 relative to the first mounting hub 252.

[0103] Referring now to FIG. 27A, FIG. 34 the retainer assembly 250 is shown from a top perspective view, with the first rotational direction Rl and the second rotational direction R2 of the retainer member 270 shown as opposite directions for vertical adjustment of the retainer member 270 relative to the first mounting hub 252. Similarly, FIG. 34 the view of the retainer assembly 250 provided in FIG. 27B shows a support member 290 operably coupled to the second mounting hub 254 for rotational movement in opposite directions R3, R4 for vertical adjustment of the retainer assembly.

[0104] Referring now to FIG. 27B, FIG. 34 the support member 290 is shown as being threadably engaged with the second mounting hub 254 at respective threaded portions 282, 283. In particular, the annular outer surface 300 of the mounting post 294 includes a threaded portion 283 that is a complementary or reverse threaded portion to the threaded portion 282 of the annular inner surface 280 of the second mounting hub 254. Thus, as the support member 290 and the second mounting hub 254 become more threadably engaged, rotational movement of the support member 290 in a first direction R3 lowers the base portion 292 relative to the second mounting hub 254. Conversely, rotational movement of the support member 290 in a second direction R4, opposite the first direction R3, raises the base portion 292 of the support member 290.
