Filed:

Dec 29, 1980

Appl. No.:

6/220897

Inventors:

John C. Killian - Sudbury MA

Assignee:

Polaroid Corporation - Cambridge MA

International Classification:

G03B 1502

US Classification:

362 8

Abstract:

A flash accessory is disclosed being releasably attachable to a photographic camera. The accessory includes a housing having a unitary latching member with a finger-engageable portion at one end and a spring portion at the other end and at least one depending finger carrying at its distal end a latching formation. The spring portion engages a section of the housing so as to bias the finger in one direction. During mounting of the accessory to the camera, the latching finger engages the camera in a manner that overcomes the biasing force of the spring portion and moves the finger and member in the opposite direction. When the finger reaches a latchable condition, the spring portion causes the finger to tightly engage with a latching section formed on the camera. Release of the latching finger is initiated by manually displacing the finger-engageable portion in the opposite direction to overcome the biasing force provided by the spring portion.

International Classification:

F16M 1300

US Classification:

340720

Abstract:

An apparatus provides a user-adjustable viewing angle for a cathode ray tube (CRT) display. The CRT may be rotated in either of two directions by depressing a control bar located along the front bezel of the display. Once set to the desired position, the control bar is released and the CRT is inhibited from rotating in both directions. Thus, the CRT may be locked in a variety of positions to suit the particular user or environmental conditions.

US Classification:

Abstract:

An expansion unit (24) that adds functions to a main computer unit (12) connects to it without cabling. The main unit (12) rests on the expansion unit, and electrical connections between the two units are thereby made automatically by complementary connectors (36, 134) on the upper surface (22) of the expansion unit and the lower surface (20) of the main unit. To insure engagement of the connectors, which the user cannot see when the main unit (12) is placed on the expansion unit (24), locating pins (26, 28) are provided on the upper surface (22) of the expansion unit (24), and guide surfaces (52, 60) guide the pins (26, 28) into the proper position as the main unit is being lowered. The two units (12, 24) are thereby properly positioned with respect to each other. To accommodate tolerances in the positioning of the connectors within the unit, the connector (36) on the expansion unit (24) is allowed to move slightly with respect to the main unit ( 12), and further guide surfaces (66) guide the connector (36) on the expansion unit (24) into engagement with the connector (134) in the main unit (12).
