The movable end of the damper is secured to the carriage assembly. The claw assembly is movable with the carriage assembly between the closed position and the open position. The claw assembly is movable relative to the carriage assembly between a non-toggle position and a toggle position. The claw assembly includes a pin receiving space defined therein that defines a claw axis that is generally vertical when the claw is in the non-toggle position and not vertical when the claw assembly is in the toggle position. ## Claims ### Claim 1 A door damper assembly comprising: a housing, a damper disposed within the housing, wherein the damper includes a fixed end and a movable end, a carriage assembly, wherein the movable end of the damper is secured to the carriage assembly, wherein the carriage assembly is movable between a closed position and an open position, a claw assembly mounted on and pivotably attached to the carriage assembly, wherein the claw assembly is movable with the carriage assembly between the closed position and the open position, wherein the claw assembly is movable relative to the carriage assembly between a non-toggle position and a toggle position, and wherein the claw assembly includes a pin receiving space defined therein that defines a claw axis that is generally vertical when the claw is in the non-toggle position, and wherein the claw axis is not vertical when the claw assembly is in the toggle position wherein the claw assembly includes a claw assembly protrusion protruding outwardly therefrom, wherein the claw assembly protrusion is received in a claw assembly slot defined in the housing, wherein the claw assembly slot includes a first portion and a second portion, wherein the first portion of the claw assembly slot is straight and the second portion of the claw assembly slot is curved, and a spring positioned to bias the carriage assembly to the closed position. ### Claim 2 (depends on 1) The door damper assembly of claim 1 wherein the carriage assembly and the claw assembly move along a carriage path having a first end and a second end as the carriage assembly moves between the closed position and the open position, and wherein the claw assembly pivots to the toggle position at the second end of the carriage path. ### Claim 3 (depends on 1) The door damper assembly of claim 1 wherein the spring has a first end secured to the housing and a second end secured to the carriage assembly. ### Claim 4 (depends on 3) The door damper assembly of claim 3 wherein the carriage assembly defines a spring receiving space therein, and wherein the spring is disposed in the spring receiving space. ### Claim 5 (depends on 4) The door damper assembly of claim 4 wherein the carriage assembly includes a spring protrusion protruding therefrom, wherein the spring protrusion is received in a spring slot defined in the housing, wherein the spring protrusion is positioned proximate the spring, and wherein the spring protrusion moves along the spring slot when the carriage assembly moves between the closed position and the open position. ### Claim 6 (depends on 1) The door damper assembly of claim 1 wherein the claw assembly is pivotably attached to the carriage assembly by a claw pivot pin. ### Claim 7 (depends on 1) The door damper assembly of claim 1, wherein the claw assembly protrusion moves along the claw assembly slot when the carriage assembly moves between the closed position and the open position, and wherein the claw assembly moves to the toggle position when the claw assembly protrusion moves through the second portion of the claw assembly slot. ### Claim 8 (depends on 1) The door damper assembly of claim 1 wherein the claw assembly includes first and second claw members, wherein the second claw member is pivotable with respect to the first claw member. ### Claim 9 (depends on 8) The door damper assembly of claim 8 wherein the second claw member is pivotable between a first position and a second position, and wherein the second claw member is biased to the first position. ### Claim 10 (depends on 9) The door damper assembly of claim 9 wherein when the carriage assembly moves between the closed position and the open position the pin receiving space defines a pin path, wherein the second claw member includes an outer inclined surface, wherein the second claw member is configured such that when a pin moving along the pin path from an open position to a closed position contacts the outer inclined surface, the second claw member pivots from the first position to the second position. ### Claim 11 (depends on 10) The door damper assembly of claim 10 wherein the second claw member is pivotably attached to the first claw by a reset pivot pin, wherein the reset pivot pin is at least partially disposed in a claw assembly protrusion that protrudes from the second claw member, wherein the reset pivot pin and claw assembly protrusion are co-axial, wherein the claw assembly protrusion is received in a claw assembly slot defined in the housing. ### Claim 12 (depends on 9) The door assembly of claim 9, wherein a claw spring extends between the carriage assembly and the second claw member, wherein the claw spring biases the second claw member to the first position. ### Claim 13 (depends on 1) The door damper assembly of claim 1 wherein the claw assembly extends downwardly through an opening in the housing such that at least a portion of the pin receiving space is located at an exterior of the housing. ### Claim 14 A door damper assembly comprising: a housing, a damper disposed within the housing, wherein the damper includes a fixed end and a movable end, a carriage assembly, wherein the movable end of the damper is secured to the carriage assembly, wherein the carriage assembly is movable between a closed position and an open position, a claw assembly pivotably attached to the carriage assembly, wherein the claw assembly is movable with the carriage assembly between the closed position and the open position, wherein the claw assembly is movable relative to the carriage assembly between a non-toggle position and a toggle position, and wherein the claw assembly includes a pin receiving space defined therein that defines a claw axis that is generally vertical when the claw is in the non-toggle position, wherein the claw axis is not vertical when the claw assembly is in the toggle position, wherein the claw assembly is pivotably attached to the carriage assembly by a claw pivot pin, wherein the claw pivot pin is at least partially disposed in a carriage assembly protrusion that protrudes from the carriage assembly, wherein the claw pivot pin and carriage assembly protrusion are co-axial, wherein the carriage assembly protrusion is received in a carriage assembly slot defined in the housing, and wherein the carriage assembly protrusion moves along the carriage assembly slot when the carriage assembly moves between the closed position and the open position, and a spring positioned to bias the carriage assembly to the closed position.
