Transilluminator

A transilluminator comprising

• a housing having therein a UV-transmissible window,
• a UV light source supported within said housing for transmitting UV light through said window,
• a UV-blocking cover,
• a hinge assembly pivotally connecting said cover to said housing for movement between a blocking position and a non-blocking position,
• a protector plate overlying said window, and
• means for securing said plate to said housing such that said plate is removable from said housing without removing said hinge assembly from said housing.

A transilluminator comprising

• a housing including a top wall having therein a UV-transmissible window and having thereon an upwardly extending projection,
• a UV light source supported within said housing for transmitting UV light through said window,
• a UV-blocking cover,
• a hinge assembly pivotally connecting said cover to said top wall for movement between a blocking position and a non-blocking position, said hinge assembly having therein an undercut, and
• a protector plate including a rearward portion which extends into said undercut when said plate is positioned over said window, and said plate also including a forward portion having therethrough an aperture through which said projection extends when said plate is positioned over said window,
• such that said plate is secured to said top wall by sliding said rearward portion of said plate into said undercut and then lowering said forward portion of said plate so that said projection extends into said aperture, and such that said plate is removed from said top wall by raising said forward portion of said plate so that said projection is removed from said aperture and then sliding said rearward portion of said plate out of said undercut.

A transilluminator comprising

• a housing including a top wall having a generally horizontal upper surface and having therein a UV-transmissible window,
• a UV light source supported within said housing and beneath said window,
• a hinge block mounted on said upper surface, said hinge block having a generally horizontal lower surface engaging said upper surface of said top wall, a generally horizontal upper surface, and a pair of opposed side surfaces connecting said upper and lower hinge block surfaces and tapering outwardly from said lower hinge block surface to said upper hinge block surface,
• a UV-blocking cover,
• a hinge pivotally connecting said cover to said upper hinge block surface for movement between a blocking position and a non-blocking position,
• a protector plate overlying said top wall upper surface and having a generally horizontal lower surface, a generally horizontal upper surface and an endless side wall connecting said upper and lower protector plate surfaces, said side wall including opposed surfaces defining a notch receiving said hinge block, said opposed side wall surfaces tapering outwardly from said lower protector plate surface to said upper protector plate, said side wall surfaces and said hinge block side surfaces mating in complementary fashion so as to prevent relative upward movement of said protector plate relative to said top wall of said housing, and said protector plate having therethrough an aperture extending from said protector plate upper surface to said protector plate lower surface, said aperture having an inner diameter and being spaced from said notch,
• a screw which extends through said aperture and which is threaded into said top wall, said screw having a head with an outer diameter less than said inner diameter of said aperture, and
• a washer having an outer diameter greater than said inner diameter of said aperture, said washer surrounding said screw between said head and said protector plate upper surface so as to prevent upward movement of said protector plate relative to said top wall of said housing, and said washer being removable from said screw so as to allow upward movement of said protector plate relative to said top wall of said housing, thereby permitting lateral movement of said protector plate relative to said top wall to remove said hinge block from said notch and allow removal of said protector plate from said housing.
