Abstract

Ein Lampenkolben (1) aus Glas ist einseitig durch eine Quetschung (2) verschlossen ist. An der Quetschung (2) ist ein Sockel (5) mittels einer Metallfeder (6) befestigt. Der Sockel (5) besitzt eine der Quetschung (2) locker angepaßte Aufnahme (7). Die Metallfeder (6;26) ist U-förmig gebogen und besteht aus einem Basisteil (11) und zwei Schenkeln (12,13), die die Quetschung umgreifen, wobei die Befestigung des Sockels (5) dadurch vermittelt wird, daß ein Schenkel (12) im wesentlichen parallel zur Längsachse ausgerichtet und so gebogen ist, daß er eine Federkraft quer zur Längsachse ausübt.

Figure 00000001
A lamp bulb (1) made of glass is closed on one side by a pinch (2). A base (5) is attached to the pinch (2) by means of a metal spring (6). The base (5) has a receptacle (7) which is loosely adapted to the pinch (2). The metal spring (6; 26) is bent into a U-shape and consists of a base part (11) and two legs (12, 13) which grip around the pinch, the attachment of the base (5) being conveyed by the fact that one leg ( 12) is aligned substantially parallel to the longitudinal axis and is bent so that it exerts a spring force transversely to the longitudinal axis.
