A trigger mechanism for an aerial device including a unitary housing having three longitudinal bores extending therethrough and a spring biased rod or wire-like mechanism which includes a plurality of bends forming various portions which can be inserted into such bores after such rod has been bent and a spring has been attached to such rod.
Claims23
A trigger mechanism for an aerial device, comprising:
- a housing comprising an upper bore extending therethrough along a first axis for attachment of said housing to a kite string;
- a lower bore extending into said housing along a second axis, and a central bore positioned between said upper and lower bore and extending through said housing along a third axis, said first, second and third axes being parallel to each other, a first slot extending through said housing to said upper bore, said first slot extending from one end of said housing to an opposite second end of said housing, a second slot extending through said housing to said central bore, said second slot extending from said one end to said opposite second end, a third slot extending through said housing to said lower bore, said third slot extending from said one end toward said opposite second end, and a fourth slot extending through said housing to said lower bore, said fourth slot being aligned with said third slot;
- a rod having a first portion which extends through said central bore, a second portion which is parallel to said first portion and which extends into said lower bore from said one end and into said fourth slot, said first and second portions being free to reciprocate within said central bore and said lower bore, respectively, said second portion being oriented for rotational movement through said third slot, said second portion being bridged to said first portion at a first end of said first portion by a third portion, and a fourth portion extending from an opposite second end of said first portion and including means for attachment of said rod to said line;
- and
- spring means for urging said fourth portion away from said housing and for urging said second portion into said lower bore.

A trigger mechanism in combination with an object which can be transported along an elevated kite string, the improvement comprising:
- a housing comprising an upper bore extending therethrough along a first axis for attachment of said housing to a kite string;
- a lower bore extending into said housing along a second axis, and a central bore positioned between said upper and lower bore and extending through said housing along a third axis, said first, second and third axes being parallel to each other, a first slot extending through said housing to said upper bore, said first slot extending from one end of said housing to an opposite second end of said housing, a second slot extending through said housing to said central bore, said second slot extending from said one end to said opposite second end, a third slot extending through said housing to said lower bore said third slot extending from said one end toward said opposite second end, and a fourth slot extending through said housing to said lower bore, said fourth slot being aligned with said third slot;
- a rod having a first portion which extends through said central bore, a second portion which is parallel to said first portion and which extends into said lower bore from said one end and into said fourth slot, said first and second portions being free to reciprocate within said central bore and said lower bore, respectively, said second portion being oriented for rotational movement through said third slot, said second portion being bridged to said first portion at said first end of said first portion by a third portion, and a fourth portion extending from an opposite second end of said first portion and including means for attachment of said rod to said line;
- spring means for urging said fourth portion away from said housing and for urging said second portion into said lower bore;
- and
- connecting means for releasably connecting to said trigger mechanism a device to be dropped from said kite string, said connecting means including a first leg having an aperture therethrough at one end thereof, said first leg being releasably connected to said trigger mechanism by said second portion extending through said aperture.
