Abstract

Abstract An enclosure comprising a first semicylindrical shell and a second semicylindrically shell juxtaposed to the first shell, the two shells being formed to fit around an object of nonuniform shape. A flexible ligamentous portion integral with both shells connects them together and acts as a hinge. One cooperating portion of a releasable lock is provided on each of the shells, one portion of the lock comprising a pair of laterally extending resilient fingers, each of the fingers having a shoulder or barb at its free end and the other a protrusion with a channel to receive the fingers. The shoulders on the fingers extend beyond the channel and hook behind it so as to prevent their inadvertent withdrawal.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 159 words
An electric motor comprising: A. A generally cylindrical body; B. Terminal means extending from the side of said body; C. At least one flange at one end of said cylindrical body and extending radially therebeyond; D. A plastic enclosure surrounding said cylindrical body and comprising: 1. first and second semicylindrical plastic shell portions, 2. a flexible hinge portion integrally formed joining contiguous edges of said first and second semicylindrical shell portions, 3. a notch in an edge portion of said first semicylindrical shell portion diametrically opposite said flexible hinge to fit closely around said terminal; and E. Locking means adjacent the edges of said first and second semicylindrical shell portions diametrically opposite said hinge to lock said shell portions around said motor, said locking means comprising: 1. integral means defining a channel on said first semicylindrical shell portion, and resiliently deformable fingers on the other of said shell portions fitting into and locking with said means defining said channel.
Claim 2
Dependent Claim 159 words
An electric motor comprising: A. A generally cylindrical body; B. Terminal means extending from the side of said body; C. At least one flange at one end of said cylindrical body and extending radially therebeyond; D. A plastic enclosure surrounding said cylindrical body and comprising: 1. first and second semicylindrical plastic shell portions, 2. a flexible hinge portion integrally formed joining contiguous edges of said first and second semicylindrical shell portions, 3. a notch in an edge portion of said first semicylindrical shell portion diametrically opposite said flexible hinge to fit closely around said terminal; and E. Locking means adjacent the edges of said first and second semicylindrical shell portions diametrically opposite said hinge to lock said shell portions around said motor, said locking means comprising: 1. integral means defining a channel on said first semicylindrical shell portion, and resiliently deformable fingers on the other of said shell portions fitting into and locking with said means defining said channel.
Claim 3
Dependent Claim 17 words
a flexible hinge portion integrally formed joining contiguous edges of said first and second semicylindrical shell portions,
Claim 4
Dependent Claim 17 words
a flexible hinge portion integrally formed joining contiguous edges of said first and second semicylindrical shell portions,
Claim 5
Dependent Claim 58 words
The motor of claim 1 in which each of said semicylindrical shell portions comprises: A. A first semicylindrical section having a diameter to fit around said generally cylindrical body; B. A second semicylindrical section of larger diameter than said first diameter to fit around said flange; and C. A shoulder between said first sections and said second sections.
Claim 6
Dependent Claim 47 words
The motor of claim 2 comprising, in addition, a plurality of inwardly extending promontories longitudinally spaced along said second semicylindrical sections from said shoulder by a distance at least substantially equal to the thickness of said flange to capture said flange between said promontories and said shoulder.
Claim 7
Dependent Claim 54 words
a notch in an edge portion of said first semicylindrical shell portion diametrically opposite said flexible hinge to fit closely around said terminal; and E. Locking means adjacent the edges of said first and second semicylindrical shell portions diametrically opposite said hinge to lock said shell portions around said motor, said locking means comprising:
Claim 8
Dependent Claim 54 words
a notch in an edge portion of said first semicylindrical shell portion diametrically opposite said flexible hinge to fit closely around said terminal; and E. Locking means adjacent the edges of said first and second semicylindrical shell portions diametrically opposite said hinge to lock said shell portions around said motor, said locking means comprising:
Claim 9
Dependent Claim 63 words
The motor of claim 2 comprising, in addition: A. A second flange longitudinally spaced from said first-named flange; and B. Gears between said flanges forming a gearbox for said motor, the longitudinal dimension of said second semicylindrical sections being substantially equal to the overall distance between the distal faces of said flanges, whereby said second semicylindrical sections comprise an enclosure for said gearbox.
