Abstract

A KeyMod quick mounting arrangement is arranged for detachably coupling an accessory at a firearm having a KeyMod mounting slot, wherein the arrangement includes a mounting body extended from the accessory, a positioning member protruded from a second side of the mounting body for detachably engaging with a narrow slot portion of the mounting slot, and a coupling head having a head portion outwardly protruded from said second side of the mounting body. In a securing position, the head portion of the coupling head is arranged for being disposed in an enlarged slot portion of the mounting slot so as to secure the accessory at the firearm. In a releasing position, the head portion of the coupling head is arranged for disengaging with the enlarged slot portion of the mounting slot so as to enable the accessory to be detached from the firearm.

First claim

What is claimed is:

1. A quick mounting arrangement for detachably coupling an accessory at a firearm having one or more mounting slots, comprising:
a mounting body having a first side adapted for extending from said accessory to be detachably coupled with said firearm, and an opposed second side;
a positioning unit which comprises a positioning member protruded from said second side of said mounting body for detachably engaging with a narrow slot portion of said mounting slot;
a coupling head, which is movably extended from said mounting body between a releasing position and a securing position, having a head portion for engaging with said mounting slot, wherein in said securing position, said head portion of said coupling head is arranged for being disposed in an enlarged slot portion of said mounting slot so as to secure said accessory at said firearm, and in said releasing position, said head portion of said coupling head is arranged for disengaging with said enlarged slot portion of said mounting slot so as to enable said accessory to be detached from said firearm; and
an actuating unit for moving said coupling head between said securing position and said releasing position, wherein said actuating unit comprises an actuating member pivotally coupled at a sidewall of said mounting body to push said head portion of said coupling head to be protruded from said second side of said mounting body in said securing position and to pull said head portion of said coupling head back to said second side of said mounting body in said releasing position, wherein said actuating unit further comprises a transmission arm having two ends pivotally coupled at said coupling head and said actuating member respectively, such that when said actuating member is pivotally moved toward said sidewall of said mounting body, said transmission arm is pivotally actuated to push said head portion of said coupling head in said securing position, and when said actuating member is pivotally moved away from said sidewall of said mounting body, said transmission arm is pivotally actuated to pull said head portion of said coupling head in said releasing position.

2. The quick mounting arrangement, as recited in claim 1 , wherein said coupling head is slidably coupled at said mounting body such that in said securing position, said head portion of said coupling head is slidably protruded from said second side of said mounting body for being disposed in said enlarged slot portion of said mounting slot, and in said releasing position, said head portion of said coupling head is slid back to align with said second side of said mounting body for disengaging with said enlarged slot portion of said mounting slot.

3. The quick mounting arrangement, as recited in claim 2 , wherein said mounting body further has a sliding slot indently formed on said second side of said mounting body, wherein said coupling head is slidably disposed at said sliding slot to guide said coupling head to slide between said securing position and said releasing position.

4. The quick mounting arrangement, as recited in claim 1 , wherein said positioning member is upwardly protruded from said second side of said mounting body for slidably engaging with said narrow slot portion of said mounting slot from said enlarged slot portion thereof.

5. A quick mounting arrangement for detachably coupling an accessory at a firearm having one or more mounting slots, comprising:
a mounting body having a first side adapted for extending from said accessory to be detachably coupled with said firearm, and an opposed second side;
a positioning unit which comprises a positioning member protruded from said second side of said mounting body for detachably engaging with a narrow slot portion of said mounting slot;
a coupling head, which is movably extended from said mounting body between a releasing position and a securing position, having a head portion for engaging with said mounting slot, wherein in said securing position, said head portion of said coupling head is arranged for being disposed in an enlarged slot portion of said mounting slot so as to secure said accessory at said firearm, and in said releasing position, said head portion of said coupling head is arranged for disengaging with said enlarged slot portion of said mounting slot so as to enable said accessory to be detached from said firearm; and
an actuating unit for moving said coupling head between said securing position and said releasing position, wherein said actuating unit comprises an actuating member pivotally coupled at a sidewall of said mounting body to push said head portion of said coupling head to be protruded from said second side of said mounting body in said securing position and to pull said head portion of said coupling head back to said second side of said mounting body in said releasing position, wherein said actuating member has a top flat supporting surface and a pushing corner extended from said supporting surface, such that when said actuating member is pivotally moved toward said sidewall of said mounting body, said coupling head is pushed by said pushing corner of said actuating member in said securing position, and when said actuating member is pivotally moved away from said sidewall of said mounting body, said coupling head is supported by said supporting surface of said actuating member in said releasing position.

6. The quick mounting arrangement, as recited in claim 5 , wherein said coupling head is slidably coupled at said mounting body such that in said securing position, said head portion of said coupling head is slidably protruded from said second side of said mounting body for being disposed in said enlarged slot portion of said mounting slot, and in said releasing position, said head portion of said coupling head is slid back to align with said second side of said mounting body for disengaging with said enlarged slot portion of said mounting slot.

7. The quick mounting arrangement, as recited in claim 6 , wherein said mounting body further has a sliding slot indently formed on said second side of said mounting body, wherein said coupling head is slidably disposed at said sliding slot to guide said coupling head to slide between said securing position and said releasing position.

8. The quick mounting arrangement, as recited in claim 5 , wherein said positioning member is upwardly protruded from said second side of said mounting body for slidably engaging with said narrow slot portion of said mounting slot from said enlarged slot portion thereof.

9. A quick mounting arrangement for detachably coupling an accessory at a firearm having one or more mounting slots, comprising:
a mounting body having a first side adapted for extending from said accessory to be detachably coupled with said firearm, and an opposed second side;
a positioning unit which comprises a positioning member protruded from said second side of said mounting body for detachably engaging with a narrow slot portion of said mounting slot;
a coupling head, which is movably extended from said mounting body between a releasing position and a securing position, having a head portion for engaging with said mounting slot, wherein in said securing position, said head portion of said coupling head is arranged for being disposed in an enlarged slot portion of said mounting slot so as to secure said accessory at said firearm, and in said releasing position, said head portion of said coupling head is arranged for disengaging with said enlarged slot portion of said mounting slot so as to enable said accessory to be detached from said firearm; and
an actuating unit for moving said coupling head between said securing position and said releasing position, wherein said actuating unit compri
