The present disclosure relates to vehicles and, more particularly, to a door hinge with a toolless removal component.
This section provides background information related to the present disclosure which is not necessarily prior art.
In the prior art, various types of door hinges are utilized on vehicles One such type of door hinge requires a nut to secure the hinge assembly that requires a tool for the door removal process. Thus, door hinge removal with a tool can be cumbersome and time consuming. Door hinges without connecting fasteners enable lifting off of the door at angles less than a full open position. This has the potential to affect the connecting components within the door system which require a disconnection before door removal (such as wire harnesses, door checks, etc.).
Additionally, various types of hinges require a T-40 nut to be secured to threads on the pivot pin. Thus, this requires a tool to remove the T-40 nut from the hinge prior to the door hinge being enabled to be lifted off of the body bracket. Accordingly, the hinge could be separated at any given angle after the nut is removed. Thus, these hinges require tools during the hinge removal process. Lack of tools, loss of tools can prevent the door removal process from occurring. Utilization of tools for door hinge removal can cause scratches or the like to the door if the tool is misused. Additionally, this requires additional steps and time to perform the door removal process when a tool is required. Also, the side door can be lifted off at any angle after the nut is removed. This results in the possibility of lifting off the side door prior to the door check link detachment.
Additionally, the nuts can be damaged during removal or installation process. The nut or the joint can be over torqued which results in stripped threads. When the nut gets cross-threaded, this results in stripped threads, damage to the lead in screw and prevents nut removal which obstructs the side door from being removed. Repetition removal, reinstallation of the nut induces wear within the joint. This may enable accelerated corrosion and prohibit further removal. Also, loose fasteners can get lost in between removal and installation. Also, numerous components create pivot bearing surfaces resulting in numerous sources of friction or rotatable torque variation. Also, entrapment of debris or containments is enabled between the nut and pivot pin due to opposing installation directions.
The disclosure provides a door hinge for a vehicle that prevents removal due to a bracket leg extending under the leaf barrel in a closed position. The present hinge enables removal or liftoff of the door due to the leg clearing the barrel when opened beyond a fully opened position. The present disclosure provides a pivot pin that extends through the barrel of the body racket or leaf.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
According to a first object of the disclosure, a hinge for a vehicle comprising a first and second leaf. The first leaf includes a barrel or knuckle to receive a pin. The barrel or knuckle has a first and second end. The second leaf includes an opening to receive the barrel or knuckle. A pair of legs extend from a body defining the opening. A first leg includes a pin to insert into the first end of the barrel or knuckle. The pin extends into the knuckle. A second leg extends adjacent to the second end of the barrel or knuckle so that in a first or closed position, the second leg blocks removal of the second leaf from the barrel or knuckle when the second leaf is moved axial along an axis of the pin to remove the door. When the second leaf moves to a second position with respect to the first leaf, the second leg clears the barrel or knuckle to enable movement of the second leaf along the pin axis to enable removal of the pin from the first leaf barrel or knuckle. The second leg has a reduced thickness and a curved portion to provide clearance for the second leaf. The second leaf has a barrel or knuckle to which the pin is fixed. The first leaf barrel or knuckle includes a pivot bushing. The pin extends through and past the second end of the first leaf barrel or knuckle. The pin includes a tapered end.
According to a second aspect of the disclosure, a vehicle door comprises a body with two sides with one of the sides including a hinge construction. The hinge construction comprises a first and second leaf. The first leaf includes a barrel or knuckle to receive a pin. The barrel or knuckle has a first and second end. The second leaf includes an opening to receive the barrel or knuckle. A pair of legs extend from a body defining the opening. A first leg includes a pin to insert into the first end of the barrel or knuckle. The pin extends into the knuckle. A second leg extends adjacent to the second end of the barrel or knuckle so that in a first or closed position, the second leg blocks removal of the second leaf from the barrel or knuckle when the second leaf is moved axial along an axis of the pin to remove the door. When the second leaf moves to a second position with respect to the first leaf, the second leg clears the barrel or knuckle to enable movement of the second leaf along the pin axis to enable removal of the pin from the first leaf barrel or knuckle. The second leg has a reduced thickness and a curved portion to provide clearance for the second leaf. The second leaf has a barrel or knuckle to which the pin is fixed. The first leaf barrel or knuckle includes a pivot bushing. The pin extends through and past the second end of the first leaf barrel or knuckle. The pin includes a tapered end.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
Turning to the figures, a vehicle is illustrated and designated with the reference numeral 10. The vehicle includes a side door 12 with a pair of hinges 14 to secure the door 12 to the vehicle 10. The door 12 may include a tubular construction or could be a solid construction if desired. Also, the door could be a tailgate, swing gate, lift gate, hood or the like.
The hinge 14 includes a body bracket or leaf 16. The leaf 16 includes a body 18 having apertures 20 to secure the leaf 16 with the vehicle 10. One end of the body 18 includes a barrel or knuckle 22. The barrel or knuckle 22 has a curved exterior with a bore 24 extending through the barrel 22. The bore 24 has a first end 26 and a second exit end 28. A pivot bushing 30 is positioned into the bore 24 to receive a pivot pin 50.
The hinge 14 includes a door bracket or second leaf 32. The leaf 32 includes a body 34 with apertures 36 that receive fasteners 38 to secure the second leaf 32 with the door 12. The body 34 includes a first leg 40 and a second leg 42 defining an opening 44. This provides the body with an overall U shape.
The first leg 40 includes a knuckle or barrel 46. The knuckle or barrel 46 includes a bore 48 that may be threaded or the like to receive the pivot pin 50. Thus, the pivot pin 50 is secured in the first leg barrel or knuckle 46. The pivot pin 50 includes a flange 52 prohibiting further insertion into the knuckle bore 48. Also, the pin 50 has a tapered portion 54 at its end to enable easy insertion into the pivot bushing 30. The pin 50 generally has a circular cylindrical shape, however, any desired shape could be utilized that fits within the pivot bushing 30 to enable the pin 50 to rotate within the pivot bushing 30.
The second leg 42 has a curved portion 56 and a reduced thickness portion 58. The curved portion 56 corresponds to the outer surface of the barrel or knuckle 22. The thin or reduced thickness portion 58 provides clearance for the second leaf in a fully opened position as seen in
When the door 12 is in a closed position in
