Abstract

Abstract The invention is a trigger switch of the type having a pistol grip shaped housing (1) with a first trigger switch (10) mounted in the upward forward portion of the housing (1) and a second trigger switch (20) mounted immediately below said first trigger switch (10) and characterized by a trigger guard (30) which is pivotally mounted at the upward end thereof to said housing (1) so that the guard (30) may be moved from a first lower position that protects the second lower switch (20) from being operated to a second upper position that allows the second switch (20) to be operated and a member (60) fixedly mounted to the housing (1) adjacent to guard (30) and extending between the first and second positions of the guard (1) and including a boss (61) thereon that extends in the direction towards said guard (60) and is adapted to engage the guard (30) when the guard (30) is moved between the first and second positions. The boss (61) being sized to provide enough force between the member (60) and the guard (30) to prevent the guard (30) from returning to the first position, unless an operator of the trigger switch supplies additional force to the guard to return it to the first position.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 207 words
In combination with a trigger switch of the type having: a pistol grip shaped housing; a first trigger switch mounted in an upper forward part of the housing; a second trigger switch mounted immediately below said first trigger switch; a trigger guard for said second trigger switch; means for pivotally mounting said trigger guard at one end thereof to said housing above said first switch so that said guard may be moved from a first lower position that protects said second switch from being operated to a second upper position that allows said second switch to be operated; and means for biasing said guard towards said first position, the improvement comprising: a member fixedly mounted to said housing adjacent said guard and extending between said first and second positions of said guard, said member including an integral projection thereon that extends in a direction towards said guard, said projection adapted to engage said guard when said guard is moved between said first and second positions, said projection being sized to provide enough force between said member and said guard, to prevent said biasing means from returning said guard to said first position unless additional force is supplied to said guard by an operator of said trigger switches.
Claim 2
Dependent Claim 207 words
In combination with a trigger switch of the type having: a pistol grip shaped housing; a first trigger switch mounted in an upper forward part of the housing; a second trigger switch mounted immediately below said first trigger switch; a trigger guard for said second trigger switch; means for pivotally mounting said trigger guard at one end thereof to said housing above said first switch so that said guard may be moved from a first lower position that protects said second switch from being operated to a second upper position that allows said second switch to be operated; and means for biasing said guard towards said first position, the improvement comprising: a member fixedly mounted to said housing adjacent said guard and extending between said first and second positions of said guard, said member including an integral projection thereon that extends in a direction towards said guard, said projection adapted to engage said guard when said guard is moved between said first and second positions, said projection being sized to provide enough force between said member and said guard, to prevent said biasing means from returning said guard to said first position unless additional force is supplied to said guard by an operator of said trigger switches.
Claim 3
Dependent Claim 56 words
The guard as recited in claim 1 including a flange along a portion of the side adjacent the end opposite of the end pivotally mounted to said housing, said flange adapted to engage said housing when said guard is in its first lower position whereby further movement of said guard towards said second switch is prevented.
Claim 4
Dependent Claim 194 words
In combination with a trigger switch of the type having: a pistol grip shaped housing; a first trigger switch mounted in an upper forward part of the housing; a second trigger switch mounted immediately below said first trigger switch; a trigger guard for said second trigger switch; means for pivotally mounting said trigger guard at one end thereof to said housing above said first switch so that said guard may be moved from a first lower position that protects said second switch from being operated to a second upper position that allows said second switch to be operated; the improvement comprising: a member fixedly mounted to said housing adjacent said guard and extending between said first and second positions of said guard, said member including an integral projection thereon that extends in a direction towards said guard, said projection adapted to engage said guard when said guard is moved between said first and second positions, said projection being sized to provide enough force between said member and said guard, to prevent said guard from returning to said first position unless additional force is supplied to said guard by an operator of said trigger switches.
Claim 5
Dependent Claim 194 words
In combination with a trigger switch of the type having: a pistol grip shaped housing; a first trigger switch mounted in an upper forward part of the housing; a second trigger switch mounted immediately below said first trigger switch; a trigger guard for said second trigger switch; means for pivotally mounting said trigger guard at one end thereof to said housing above said first switch so that said guard may be moved from a first lower position that protects said second switch from being operated to a second upper position that allows said second switch to be operated; the improvement comprising: a member fixedly mounted to said housing adjacent said guard and extending between said first and second positions of said guard, said member including an integral projection thereon that extends in a direction towards said guard, said projection adapted to engage said guard when said guard is moved between said first and second positions, said projection being sized to provide enough force between said member and said guard, to prevent said guard from returning to said first position unless additional force is supplied to said guard by an operator of said trigger switches.
Claim 6
Dependent Claim 56 words
The guard as recited in claim 3 including a flange along a portion of the side adjacent the end opposite of the end pivotally mounted to said housing, said flange adapted to engage said housing when said guard is in its first lower position whereby further movement of said guard towards said second switch is prevented.
