COLD PROTECTION COVER FOR TEACHING OPERATION PANEL

摘要

PROBLEM TO BE SOLVED: To provide a cold protection cover for a teaching operation panel which can lightly use the teaching operation panel, manufactured by taking use at an ordinary temperature into consideration, without a trouble even under a low temperature environment. ;SOLUTION: A cold protection cover 1 is formed by an outer skin 2 and a heat insulating element 3, in a surface side thereof, an inspection window is provided, so that a display 9a and a switch operating part 9b of a teaching operation panel 9 can be visually seen, and, on the other hand, in a reverse side of the cold protection cover 1, a heater wire 10 is placed to crawl, to serve as a heat insulating means. A squeezing sleeve 6 is mounted in an opening 5 inserting a hand of a person, and infiltration of the outside air is prevented. By the cold protection cover 1, since a comfortable temperature can be maintained for both the teaching operation panel 9 and the hand of a person, the display operating panel of ordinary temperature specification can be used under a low temperature environment, and, by dispensing with wearing a cold protection glove or the like, even under the low temperature environment, the teaching operation panel can be freely manipulated by a naked hand.;COPYRIGHT: (C)1998,JPO
