Quick coupler system
A system for coupling an implement to a machine. A coupler body includes first and second opposed coupler sidewalls, each including a lock pin coupler receiving region therein, and at least one transverse member coupled to the first and second opposed side walls. An attachment member includes first and second opposed attachment member sidewalls. Each attachment sidewall includes a hook member at a first end thereof and a lock pin attachment receiving region at a second end thereof. The lock pin attachment receiving regions are configured to selectively align with the lock pin coupler receiving regions when the hook members have received a transverse member. A lock pin is sized to be accepted by each lock pin coupler receiving region and each lock pin attachment receiving region when aligned with each other.
1 . A system for coupling an implement to a machine, comprising:
a coupler body including:
first and second opposed coupler sidewalls, each including a lock pin coupler receiving region therein, and
at least one transverse member coupled to the first and second opposed side walls;
an attachment member including first and second opposed attachment member sidewalls, each attachment sidewall including a hook member at a first end thereof and a lock pin attachment receiving region at a second end thereof, the lock pin attachment receiving regions configured to selectively align with the lock pin coupler receiving regions when the hook members have received a transverse member; and
a lock pin sized to be accepted by each lock pin coupler receiving region and each lock pin attachment receiving region when aligned with each other,
wherein when each hook member has received a transverse member and the lock pin attachment receiving regions are aligned with the lock pin coupler receiving regions, the lock pin is capable of mating with each of the lock pin attachment receiving regions and each of the lock pin coupler receiving regions, securing the coupler body to the attachment member.
2 . The system of claim 1 , wherein each of the at least one transverse member comprises:
a pin extending between the first and second opposed coupler sidewalls;
a first pin boss for operatively connecting the pin to the first coupler sidewall; and
a second pin boss for operatively connecting the pin to the second coupler sidewall.
3 . The system of claim 1 , wherein when each hook member has received a transverse member, the implement can be raised by the machine without first securing the attachment member to the coupler body via the lock pin.
4 . The system of claim 1 , wherein each hook member is arranged such that the weight of the attachment member and the implement work in favor of aligning the lock pin attachment receiving regions and the lock pin coupler receiving regions.
5 . The system of claim 1 , wherein the attachment member is coupled to a grapple.
6 . The system of claim 1 , further comprising a safety pin configured to selectively inhibit the lock pin from being released from the lock pin coupler receiving regions and the lock pin attachment receiving regions.
7 . The system of claim 1 , wherein each lock pin attachment receiving region comprises a bore formed within one of the attachment side walls.
8 . A system for coupling an implement to a machine, comprising:
a coupler body including:
first and second opposed coupler sidewalls, each including a lock pin coupler receiving region therein, and
first and second transverse members each coupled to the first and second opposed coupler side walls;
an attachment member including first and second opposed attachment member sidewalls, each attachment member sidewall including a hook member at a first end thereof and a lock pin attachment receiving region, the lock pin attachment receiving regions configured to selectively align with the lock pin coupler receiving regions when the hook members have received the first transverse member; and
a lock pin sized to be accepted by each lock pin coupler receiving region and each lock pin attachment receiving region when aligned with each other,
wherein when each hook member has received the first transverse member and the lock pin attachment receiving regions are aligned with the lock pin coupler receiving regions, the lock pin is capable of mating with each of the lock pin attachment receiving regions and each of the lock pin coupler receiving regions, securing the coupler body to the attachment member.
9 . The system of claim 8 , wherein each of the at least one transverse member comprises:
a pin extending between the first and second opposed coupler sidewalls;
a first pin boss for operatively connecting the pin to the first coupler sidewall; and
a second pin boss for operatively connecting the pin to the second coupler sidewall.
10 . The system of claim 8 , further comprising a safety pin configured to selectively inhibit the lock pin from being released from the lock pin coupler receiving regions and the lock pin attachment receiving regions.
11 . The system of claim 8 , wherein each lock pin attachment receiving region comprises a bore formed within one of the attachment side walls.
12 . The system of claim 8 , wherein when each hook member has received the first transverse member, the implement can be raised by the machine without first securing the attachment member to the coupler body via the lock pin.
13 . The system of claim 8 , wherein each hook member is arranged such that the weight of the attachment member and the implement work in favor of aligning the lock pin attachment receiving regions and the lock pin coupler receiving regions.
14 . A coupling system, comprising:
a coupler body including:
first and second opposed coupler sidewalls, each including a lock pin coupler receiving region therein,
at least one transverse member coupled to the first and second opposed coupler side walls, and
a plurality of bosses for operatively connecting the at least one transverse member to the first and second opposed sidewalls; and
an attachment member including first and second opposed attachment member sidewalls, each attachment member sidewall including a hook member and a lock pin attachment receiving region, the lock pin attachment receiving regions configured to selectively align with the lock pin coupler receiving regions when the hook members have received the first transverse member; and
a lock pin sized to be accepted by each lock pin coupler receiving region and each lock pin attachment receiving region when aligned with each other.
15 . The coupling system of claim 14 , wherein each lock pin attachment receiving region comprises a bore formed within one of the attachment side walls.
16 . The coupling system of claim 15 , further comprising a safety pin configured to selectively inhibit the lock pin from being released from the lock pin coupler receiving regions and the lock pin attachment receiving regions.
17 . The coupling system of claim 14 , wherein the at least one transverse member comprises two transverse members.
18 . The coupling system of claim 14 , further comprising an implement coupled to the attachment member.
19 . The coupling system of claim 18 , wherein when each hook member has received the first transverse member, the implement can be raised by the machine without first securing the attachment member to the coupler body via the lock pin.
20 . The coupling system of claim 18 , wherein each hook member is arranged such that the weight of the attachment member and the implement work in favor of aligning the lock pin attachment receiving regions and the lock pin coupler receiving regions.
