DETAILED DESCRIPTION

[0038] Referring to FIG. 1, the numeral 10 generally designates an opening cover, which is adapted to cover, and optionally seal, an opening 12 in an apparatus 14, such as a medical apparatus. As will be more fully described below, cover 10 is coupled to apparatus 14 so that it is movable between a first position in which the cover closes the opening 12 and a second position where the opening 12 is, at least partially if not entirely, uncovered and accessible.

[0039] As best seen in FIGS. 1-3, opening cover 10 includes a cover body 16 that includes a central axis 10a orthogonal to the cover body 16 and which is adapted to couple to body or housing 18 of apparatus 14 about an axis of rotation 20. Axis of rotation 20 is angled to the surface 12a about opening 12 so that the cover can rotate about the axis of rotation 20 to move between a first position wherein the cover 10 extends over and closes the opening 12 and a second position wherein the cover 10 is moved (e.g. to the side of opening 12) to allow access the opening 12. Further, as will be more fully described below, in one embodiment, axis of rotation 20 moves in a conical path so that cover 10 twists and spins out of opening 12 when it is moved to its second position.

[0040] As shown, in the illustrated embodiment, the axis of rotation 20 of the cover 10 is offset from the central axis 10a of cover 10 and, optionally, located at or near the edge of the cover, which further allows for the axis of rotation to be able to tip and have the cover ride freely out of the opening, as will be more fully understood from the description that follows. In the illustrated embodiment, cover body 16 is circular. However it should be understood that cover body 16 may have other shapes.

[0041] Referring again to FIGS. 2-3, cover 10 further includes a pivot member in the form of a cylindrical member 24. Cylindrical member 24 pivotally mounts cover 10 to apparatus 14 about axis 20 and, further, as will be more fully described below, retains cover 10 on apparatus 14. Cylindrical member 24 may be mounted to cover 10 or may be integrally formed therewith.

[0042] As best seen in FIG. 4, opening 12 is formed by a recess 26 in apparatus body 18. Optionally, recess 26 is formed in a wall 22 of apparatus body 18. However, it should be understood that cover 10 may be mounted to an apparatus body that is a solid body instead (such as shown and described in reference to FIG. 5B). Recess 26 forms a shoulder 28 and a through hole 30 that is offset in the recess 26 to form an enlarged shoulder 28a on one side of through hole 30. Enlarged shoulder 28a includes a transverse passageway 28b through which cylindrical member 24 extends for coupling cover 10 to apparatus body 18.

[0043] As understood from FIG. 5, cover 10 is further coupled to the apparatus body 18 by a fastener 32. As best seen in FIG. 5A, fastener 32 extends into the open threaded end 24a (FIG. 3) of cylindrical member 24, which extends through passageway 28b of enlarged shoulder 28a. Optionally, cover 10 further includes a spring 34 to bias the cover 10 toward apparatus body 18 and into its first position. For example, as best seen in FIG. 5A, the spring 34 is mounted about cylindrical member 24 and about the axis of rotation 20 of cover 10. Optionally, cover 10 includes a washer 36 (FIG. 5A) between the head of fastener 32 and apparatus body 18, with the spring 34 being mounted about the cylindrical member 24 between the washer 36 and the apparatus body 18.

[0044] As best seen in FIGS. 1 and 4, cover body 16 has a size and a shape that are substantially equal to the size and the shape of the recess 26 so that when cover body 16 is moved to its first position over opening 12, cover body 16 will seat in and fully close opening 12, and further seat on shoulder 28. In this manner, cover 10 effectively seals opening 12 when cover 10 is in its first position. Optionally, opening 12 may incorporate a seal about opening 12, such as O-ring seal, which may be seated on shoulder 28. Further, as best seen in FIGS. 1 and 4, when cover 10 is in its first position, cover body 16 is flush with apparatus body 18, which facilitates cleaning.

[0045] As noted above, axis 20 may move as cover 10 is moved between its first and second positions. For example, as best seen in FIG. 5A, passageway 28b may be sized greater than outside diameter of cylindrical member 24 to provide play between cylindrical member 24 and apparatus body 18. In this manner, as cover 10 is rotated out of opening 12, cylindrical member 24 will tilt in passageway 28b against the biasing force of the spring and axis 20 will move in a conical path so that cover 10 will tilt and twist out of opening 12.

[0046] As best in FIG. 2, cover 10 also includes an engagement structure 40 for engagement by (1) a tool or (2) a finger of a person. For example, a suitable engagement structure includes a (1) a slot, (2) a recess, or (3) a high friction surface. Further, the engagement structure 40 may be located offset from axis of rotation 20 so that when a force is applied by a person's finger or tool, cover 10 will pivot about axis of rotation 20. Alternately, the engagement structure 40 may align with the axis of rotation 20, for example, when configured to work with a tool, such as a screwdriver.

[0047] To facilitate rotation of cover 10 from its first position to its second position, cover body 16 may have a tapered edge 16a (FIGS. 3 and 4). Similarly, recess 26 may include a tapered side wall 26a (FIG. 4), which may have the same or similar taper to tapered edge 16a. Thus, tapered side wall 26a can guide cover 10 outwardly from recess 26 as cover 10 is rotated about axis of rotation 20. In other words, the interaction between the two tapers translates the rotational movement of the cover into sliding motion of the cover outwardly from recess 26 to thereby move the cover 10 out of the opening 12.

[0048] Cover 10 may be formed from a wide selection of materials, including plastic or metal or wood, or a composite material.

[0049] As noted above, cover 10 may be used on an apparatus with a solid apparatus body, such as shown in FIG. 5B. Referring to FIG. 5B, apparatus 114 includes an apparatus body 118 with an opening 112. Opening 112 is formed by a recess 126 that extends into the outer surface of apparatus body 118. Similar to recess 26, recess 126 forms a through hole 130 that forms an access opening or an attachment point that is recessed within apparatus 114.

[0050] Cover 10 is mounted in opening 112 on a flange 128, which extends into recess 126 to form a mounting surface for cover 10. Similar to shoulder 28, flange 128 includes a transverse passageway 128b for receiving cylindrical member 24 of cover 10. In a similar manner to the previous embodiment, cover 10 is secured in opening 112 by a fastener 32 and washer 36, with fastener 32 extending into and engaging the open end of cylindrical member 24. Spring 34 is similarly captured between washer 36 and the underside of flange 128 to apply a biasing force to cover 10. Again the size of passageway 128b may be greater than the cylindrical member 24 so that cylindrical member 24 can tilt in passageway to allow axis of rotation 20 to pivot and tilt, as described above. Similar to the previous embodiment, recess 126 may include a tapered perimeter to form a tapered interface with cover 10 to facilitate guiding cover 10 out of opening 112 when a force is applied to cover 10 by a finger or tool, as noted above. For further details of how cover 10 and apparatus body 118 cooperate, reference is made to the first embodiment.

[0051] Accordingly, cover 10 is configured to cover the opening and hole located in the opening, but is movable while remaining attached to the apparatus. Cover 10 is secured in place to cover the opening, but is allowed to pivot or spin out of position when rotated to thereby uncover the opening, and then rotated back into place. Receding the cover in place avoids unintended opening of the cover. Further, the spring applies a force to the cover that pulls it back into the opening. As noted, the angled interface between the cover and the respective opening allows for the cover to be guided out of the opening when a rotational force is applied and settle back into position in the opening when a rotational force is applied in the opposed direction. As described, the rotational force can be applied by a finger pressing on the engagement structure, such as an indent, which is offset from the rotational axis of the cover, or by way of a tool inserted into a slot, which may be offset as well or located above the rotational axis of the cover.
