Abstract
Abstract A disposable plastic handle and shield in the form of a first embodiment including a unitary injection molded hollow handle with a threaded upper end portion for engagement with a threaded receptacle on the luminaire of a hospital operating room. An integral, generally circular shield is connected to the handle between the threaded upper end portion and a lightly knurled portion of the handle. The shield includes a pair of spaced apart grooves on its underside, one on each side of the handle serving as live hinges and defining a pair of segments capable of being folded down against the knurled handle or upward against the threaded end of the handle to facilitate packaging. A second embodiment has a shield similar to the first embodiment but which is separate from, rather than integral with, the plastic handle. The shield has a central aperture with a thread that engages the thread of the handle and guides the shield down into abutting engagement with a shoulder integral with the handle at the base of the handle thread.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A disposable, sterile plastic handle for directing an overhead luminaire used in a hospital operating room and comprising, in combination: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) means defining a plurality of minute indentations in said handle defining a gripping area; (c) a protective circular shield integral with said handle and situated between said gripping area of said handle and said threaded upper end portion of the latter; (d) a relatively small diameter peripheral bead bordering said circular shield; (e) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing said shield into a central section integrally connected to said handle and a pair of segmental sections outboard from said central section; and (f) said grooves in said shield leaving relatively thin flexible hinge connections between said central section and said segmental sections.
Claim 2
Dependent Claim
149 words
A disposable, sterile plastic handle for directing an overhead luminaire used in a hospital operating room and comprising, in combination: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) means defining a plurality of minute indentations in said handle defining a gripping area; (c) a protective circular shield integral with said handle and situated between said gripping area of said handle and said threaded upper end portion of the latter; (d) a relatively small diameter peripheral bead bordering said circular shield; (e) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing said shield into a central section integrally connected to said handle and a pair of segmental sections outboard from said central section; and (f) said grooves in said shield leaving relatively thin flexible hinge connections between said central section and said segmental sections.
Claim 3
Dependent Claim
30 words
The disposable plastic handle and shield of claim 1 wherein said shield is reinforced by a small peripheral bead having a diameter slightly greater than the thickness of said shield.
Claim 4
Dependent Claim
135 words
A disposable plastic handle for use on an overhead luminaire in a surgical suite and comprising the combination of: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) a protective circular shield integral with said handle and situated adjacent the lower end of said threaded upper end portion; (c) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing same into a central section integral with said handle and a pair of segmental sections outboard from said central section; (d) said grooves in said shield defining relatively thin flexible hinge connections between said central section and said segmental sections; and (e) each said segmental section being capable of moving through an arc of substantially 180 degrees upwardly or downwardly for packaging.
Claim 5
Dependent Claim
135 words
A disposable plastic handle for use on an overhead luminaire in a surgical suite and comprising the combination of: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) a protective circular shield integral with said handle and situated adjacent the lower end of said threaded upper end portion; (c) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing same into a central section integral with said handle and a pair of segmental sections outboard from said central section; (d) said grooves in said shield defining relatively thin flexible hinge connections between said central section and said segmental sections; and (e) each said segmental section being capable of moving through an arc of substantially 180 degrees upwardly or downwardly for packaging.
Claim 6
Dependent Claim
142 words
A disposable, sterile plastic handle for use on an overhead luminaire in a surgical suite comprising, in combination: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) a shoulder integral with said handle between said threaded upper end portion and the gripping area of said handle; (c) a protective circular shield bordered by a small diameter peripheral bead; (d) said shield having a relatively large diameter threaded central aperture engaging said shoulder of said handle; (e) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing it into a central section threaded down against said shoulder and a pair of segmental sections outboard from said central section; and (f) said grooves in said shield leaving relatively thin flexible hinge connections between said central section and said segmental sections.
Claim 7
Dependent Claim
142 words
A disposable, sterile plastic handle for use on an overhead luminaire in a surgical suite comprising, in combination: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) a shoulder integral with said handle between said threaded upper end portion and the gripping area of said handle; (c) a protective circular shield bordered by a small diameter peripheral bead; (d) said shield having a relatively large diameter threaded central aperture engaging said shoulder of said handle; (e) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing it into a central section threaded down against said shoulder and a pair of segmental sections outboard from said central section; and (f) said grooves in said shield leaving relatively thin flexible hinge connections between said central section and said segmental sections.
Claim 8
Dependent Claim
21 words
The combination set forth in claim 4, wherein said handle includes a plurality of minute indentations defining a gripping area thereon.
Claim 9
Dependent Claim
33 words
The combination set forth in claim 4, wherein each said segmental section is capable of moving on said flexible hinge connections through an arc of substantially 180 degrees upwardly or downwardly for packaging.
Claim 10
Dependent Claim
52 words
The combination set forth in claim 5, wherein said handle with said shield screwed down against said shoulder may be threaded into the socket of a surgical suite luminaire locking all sections of said shield in a rigid coplanar position precluding loss of sterility when the handle is gripped by the surgeon.
Claim 11
Dependent Claim
136 words
A disposable, sterile plastic handle for directing an overhead luminaire used in a hospital operating room and comprising, in combination: (a) a hollow plastic handle with a threaded upper end portion and a closed lower end; (b) means defining a plurality of minute indentations in said handle defining a gripping area; (c) a protective circular shield mounted on said handle between said gripping area of said handle and said threaded upper end portion of the latter; (d) means defining a pair of laterally spaced parallel grooves in the underside of said shield dividing said shield into a central section integrally connected to said handle and a pair of segmental sections outboard from said central section; and (e) said grooves in said shield leaving relatively thin flexible hinge connections between said central section and said segmental sections.
Claim 12
Dependent Claim
136 words
