Abstract
A handle for an electronic instrument housing includes an elongated grip portion. The grip portion includes two elongated elements each having opposed ends. The elements are connected to each other to form an elongated chamber. An elastomeric layer encompasses an intermediate portion of the grip portion, and the grip portion has a vent aperture communicating with the chamber. The vent aperture may be beyond the elastomeric layer, at one or both ends. One of the elongated elements may form a channel with tapered edge surfaces receiving the other element, so that pressure of elastomeric molding tends to wedge the parts together to form a seal against incursion of the elastomer.
Claims6
A carrying handle comprising:
- a first elongated element having opposed first and second ends, at least one of the first and second ends of the first element including a flange;
- a second elongated element connected to the first elongated element, the second elongated element having opposed first and second ends wherein at least one of the first and second ends includes an integral end element for cooperating with the respective flange of the first elongated element;
- the first and second elements defining a chamber extending from the first end to the second end of the first element;
- a pair of extension elements, each attached to a respective end of the first element, and angularly offset therefrom, such that free ends of the extension elements are operable for connection to an instrument to provide the carrying handle;
- at least one of the extension elements including an end panel having a flat inner face connected to the respective flange of the first elongated element, wherein the respective flat inner face, flange and integral end element cooperate to define the aperture at the at least one of the first and second ends of the first elongated element;
- an elastomeric layer encompassing an intermediate portion of the first and second elongated elements, said elastomeric layer being applied by an injection molding process;
- and
- said aperture allowing air injected in said molding process to escape from said chamber.
