Attachment assembly for a vehicle
View Patent ↗An attachment assembly for a vehicle having a receiver for pulling an object or being pulled. The attachment assembly includes a support member for connection to the receiver and an attachment member connected to the support member to provide both pivotal and rotational movement.
1. An attachment assembly comprising:
a support member extending longitudinally about a longitudinal axis, the support member adapted and configured to be engaged with a receiver of a vehicle;
a flange plate extending from the support member, the flange plate generally perpendicular to the longitudinal axis, the flange plate comprising an aperture; and
an attachment member attached to the support member by a shaft member inserted into the aperture of the flange plate, the attachment member having a closed loop, the shaft member comprising an aperture disposed and fully enclosed in the shaft member, the closed loop disposed in the aperture of the shaft member, the attachment member being both rotatable about the longitudinal axis relative to the support member and moveable along the attachment member's closed loop length within the aperture to provide both rotational movement and movement along the closed loop length for pulling an object with the vehicle or the vehicle being pulled.
2. The attachment assembly of claim 1 , wherein the shaft member is rotatably coupled to the support member and rotatable about the longitudinal axis relative to the support member, the shaft member including the aperture through which the closed loop of the attachment member is disposed.
3. The attachment assembly of claim 2 , wherein the attachment member is pivotal relative to the shaft member about a pivot axis that extends through the aperture.
4. The attachment assembly of claim 3 , wherein the pivot axis is perpendicular to the longitudinal axis.
5. The attachment assembly of claim 1 , wherein the attachment member has a generally circular cross-sectional shape sized to moveably fit within the aperture.
6. The attachment assembly of claim 1 , wherein the attachment member rotates 360 degrees about the longitudinal axis.
7. The attachment assembly of claim 1 , wherein the closed loop is formed from straight bar stock extended through the aperture and welded into the closed loop.
8. An attachment assembly comprising:
a longitudinally extending support member, the support member adapted and configured to be engaged with a receiver of a vehicle;
a flange plate extending generally perpendicularly from the support member, the flange plate comprising an aperture
a shaft member inserted through the aperture and attached to the support member, the shaft member rotating relative to the support member about a longitudinal axis, the shaft member comprising an aperture disposed and fully enclosed in the shaft member; and
an attachment member formed as a permanently closed loop which extends through the aperture, the closed loop connected to the aperture of the shaft member, the attachment member rotating generally 360 degrees about the longitudinal axis with rotation of the shaft member and being pivotal relative to the support member about a pivot axis to provide both pivotal and rotational movement for pulling an object with the vehicle or the vehicle being pulled,
wherein a force axis of the object is centered during pulling due to the pivoting and rotating of the attachment member.
9. The attachment assembly of claim 8 , wherein the attachment member has a generally circular cross-sectional shape sized to moveably fit within the aperture and the attachment member can move along the attachment member's closed loop length within the aperture.
10. The attachment assembly of claim 8 , wherein the pivot axis is perpendicular to the longitudinal axis.
11. The attachment assembly of claim 8 , wherein the attachment member pivots through at least 180 degrees.
12. An attachment assembly comprising:
a support member extending longitudinally about a longitudinal axis, the support member adapted and configured to be engaged with a receiver of a vehicle;
a flange plate extending from the support member, the flange plate generally perpendicular to the longitudinal axis, the flange plate comprising an aperture;
an attachment member inserted through the aperture and connected to the support member and being both rotatable about the longitudinal axis relative to the support member and pivotal relative to the support member to provide both pivotal and rotational movement for pulling an object with the vehicle or the vehicle being pulled; and
a shaft member attached to the support member, wherein the shaft member rotates relative to the support member about the longitudinal axis and the attachment member is connected to the shaft member and pivots relative to the shaft member, whereby the shaft member includes an aperture disposed and fully enclosed in the shaft member and the attachment member is a permanently closed loop that extends through the aperture.
13. An attachment assembly comprising:
a support member extending longitudinally about a longitudinal axis, the support member adapted and configured to be engaged with a receiver of a vehicle;
a flange plate extending from the support member, the flange plate generally perpendicular to the longitudinal axis, the flange plate comprising an aperture; and
an attachment member connected to the support member by a shaft member, the attachment member having a closed loop, the shaft member comprising an aperture disposed and fully enclosed in the shaft member, the closed loop is disposed in the aperture of the shaft member, the attachment member being rotatable about the longitudinal axis relative to the support member and pivotal relative to the support member to provide both pivotal and rotational movement for pulling an object with the vehicle or the vehicle being pulled.
14. The attachment assembly of claim 13 , wherein the shaft member is rotatably coupled to the support member and rotatable about the longitudinal axis relative to the support member, the shaft member including the aperture through which the closed loop of the attachment member is disposed.
15. The attachment assembly of claim 14 , wherein the attachment member is pivotal relative to the shaft member about a pivot axis that extends through the aperture.
16. The attachment assembly of claim 15 , wherein the pivot axis is perpendicular to the longitudinal axis.
17. The attachment assembly of claim 13 , wherein the attachment member has a generally circular cross-sectional shape sized to moveably fit within the aperture.
18. The attachment assembly of claim 13 , wherein the attachment member rotates 360 degrees about the longitudinal axis.
19. The attachment assembly of claim 13 , wherein the closed loop is formed from straight bar stock extended through the aperture and welded into the closed loop.
