DETAILED DESCRIPTION OF EMBODIMENTS
With reference now to FIGS. 1 and 2, an embodiment of the invention is shown as an access door 10 for an ice storage bin. In the example shown in FIG. 1, the access door 12 mounts on two tracks 14 and 16 located adjacent to an access opening 20 of a storage bin 22. In the example shown, the tracks 14, 16 are respectively located in the upper portion and lower portion of the access opening 20. In other embodiments, the tracks can be located in other portions of the access opening 20, such as on opposing lateral sides or portions of the access opening 20.
The access opening 20 can be defined on any surface of the bin 22, including the front surface as shown. Alternatively, the access opening 20 could be defined on either of the side surfaces, the back surface, or the upper surface of the bin 22. The opening 20 can be any general shape, but a rectangular or square-shaped access opening 20 is suitable. In addition, the access opening 20 can be located at several different heights with respect to the bin 22. In the embodiment shown, the access opening 20 can be located slightly above that of the expected or typical height of the contents of the storage bin 22. For example, the access opening 20 can be located on the front surface of the bin 22 slightly above the expected or typical height of ice stored within the bin 22.
Two tracks 14 and 16 are located adjacent to the edges of the access opening 20. The tracks 14 and 16 can be located on the horizontal or vertical edges of the access opening 20, but as shown the tracks 14, 16 can be respectively located adjacent to the upper and lower horizontal edges. The tracks 14 and 16 can be any suitable track capable of receiving a portion of an access door 12, and permitting sliding movement of the access door 12 with respect to the storage bin 22. In the embodiment shown in FIG. 3, the tracks 14 and 16 have a generally square “U”-shaped profile, and the upper portion and lower portion of the access door 12 can fit within a portion of the respective square “U”-shaped tracks 14, 16. Other types of tracks can be used, however, and the invention is not limited to the particular track configuration shown. For example, a track could have a “T”-shaped profile, wherein an extended portion associated with the track could fit into a corresponding channel adjacent to an edge of the access door. In another example, a track could have a “L”-shaped profile, wherein an underside portion of the access door can contact a vertically raised portion of the track. Also, the upper track 14 could be a different type or configuration than the lower track 16 depending on user selection, type or shape of access door, or desired functionality. Alternatively, an access door, such as 12, could be mounted to an access opening, such as 20, without the use of any tracks, such as 14 and 16, and the access door could be mounted using other types of mounting devices, such as hinges, swivels, or other connection-type devices, in accordance with embodiments of the invention.
When it is desired to access or view the contents within the storage bin 22, a user can slide the access door 12 within the tracks 14 and 16 to provide user access to the interior of the bin 22 through the access opening 20. As shown in the example of FIG. 2, the sliding movement is shown in either of the horizontal directions In other configurations, the sliding movement may be in a vertical direction or other directions depending on the position and configuration of the access door with respect to the tracks. As shown in FIG. 2, the access door 12 can slide back and forth in either of the horizontal directions. A user can slide the access door 12 by grasping a portion of the access door 12 and either pulling or pushing the access door 12 to either side in the horizontal direction. Alternatively, there may be a cut-out 28 (shown in FIG. 6), handle, or other device mounted to the access door 12 for a person to grasp and to slide the access door 12 to either side in either of the horizontal directions.
FIG. 4 shows a sectional front view of the access door 12 shown in FIG. 2, wherein a portion of the tracks 14 and 16 has been cut away to view details associated with the access door 12 and tracks 14, 16. As shown, the access door 12 can include a number of protrusions 24 along the upper edge of the access door 12, and a plurality of corresponding recesses 26 along both the upper track 14 and/or the lower track 16. The embodiment shown in FIG. 4 shows a plurality of protrusions 24 and a plurality of corresponding recesses 26. In another embodiment, an access door such as 12 may only have one protrusion 24 and an associated track may only have one corresponding recess 26. Other embodiments may have any number of protrusions and corresponding recesses. In this embodiment the access door 12 can be positioned with the protrusions 24 adjacent to either the upper track 14 or the lower track 16. In another embodiment, only one of the upper or lower tracks may have recesses, such as 26. In such an embodiment, the access door, for example 12, could be positioned with the protrusions, such as 24, adjacent to the appropriate track that includes recesses, such as 26.
When a user desires to remove the access door 12 from the storage bin 22, the protrusions 24 associated with the access door 12 can be aligned with the corresponding recesses 26 associated with the tracks 14 or 16. In this manner, the access door 12 can be moved so that the protrusions 24 are engaged with or are otherwise aligned with the corresponding recess 26 as shown in FIG. 5, or if only one protrusion and recess exist, so that the protrusion is engaged with or is otherwise aligned with the corresponding recess. Accordingly, the upper edge of the access door 12 can be manipulated further upward within the upper track 14, and the lower edge of the access door 12 can be moved above the edge of the lower track 16 such that the lower portion of the access door 12 can be rotated away (as shown by arrows 30 in FIG. 5) from the lower track 16 until the lower edge of the access door 12 clears the lower track 16. The upper edge of the access door 12 can then be removed from the upper track 14, and the access door 12 can be removed completely from the bin 22. With the access door 12 removed from the storage bin 22, the access door 12 can be cleaned, repaired, or otherwise worked on separately from the storage bin 22. In addition, the upper track 14, lower track 16, and their respective recesses 26 can be cleaned, repaired, or otherwise worked on separately from the access door 12.
When a user desires to install the access door 12 with respect to the storage bin 22, the protrusions 24 of the upper edge of the access door 12 can be aligned and engaged with the corresponding recesses 26 in the upper track 14. Likewise, if only one protrusion and corresponding recess exist, then the protrusion is aligned and engaged with the corresponding recess. In any instance, the lower edge of the access door 12 can be rotated so that the lower edge is positioned within the bottom track 16 and then the lower edge of the access door 12 can be lowered within the lower track 16. In this manner, the access door 12 moves slightly downward from the upper track 14 causing the protrusions 24 to remain aligned with the corresponding recesses 26 and maintaining the upper edge of the access door 12 within the upper track 14. The access door 12 can be moved in a horizontal direction as shown in FIG. 2, and the protrusions 24 and recesses 26 will become unaligned while permitting the access door to slide with respect to the upper track 14 and lower track 16.
One skilled in the art will recognize other configurations, shapes, and designs can exist in accordance with other embodiments of the invention. It will be recognized by those skilled in the art that changes may be made in the above described embodiments of the invention without departing from the concepts thereof. The invention is not limited to the particular embodiments disclosed, but is intended to cover all modifications that are within the scope of the invention.
