Abstract

A door hinge for vehicles is described. The hinge includes a first pivotal means 30 connecting a body 10 of said vehicle and an upper section 18 of a door 14 of said vehicle; a second pivotal means 32 connecting said upper section 18 and a lower section 16 of said door.

Description

Description FIELD OF THE INVENTION
The field of the present invention is that of automotive door hinges.
BACKGROUND OF THE INVENTION
It is well known that there may be some inconveniency to open an automobile door with conventional hinge mechanism, which renders the door to rotate a pin close to the door's front internal edge, or its main movement being above rotation. When the door is opened in a parking lot with another vehicle on the same side as the door to the discussed vehicle, said door sometimes can't be fully opened, otherwise said door may collide with another vehicle.
Some prior arts proposed foldable doors, ,such as JP2003146082 by Yoshida et al, and DE4227411 by Klaus et al. But JP2003146082 utilize two sets of four-bar linkages leading to very complicated manufacturing issues; while DE4227411 utilizes a first pivotal means mounting on an inclined pillar, and a second pivotal means is angled with the first pivotal means at usually more than 30 degrees, which makes operation for opening the door inconvenient. Neither each of above prior arts discussed about how does the lower hinge work when the door is opened or half opened for a door with an adjustable glass.

SUMMARY OF THE INVENTION
To overcome the aforementioned drawbacks, the present invention is brought forth.
A first pivotal means 30 connects an upper section 18 of a door 14 with a body 10, usually at a border area of a roof 20 of said body 10; a second pivotal means connects a lower section 16 of door 14 with upper section 18, usually at a position close to the lowest visible edge of a glass mounted within upper section 18;
There is a pin 28 on a vertical edge side of lower section 16, said pin 28 being able to slide along a slot 26 on a vertical section of a pillar, when the door is just opened, upper section 18 revolves around a first pivotal means 30, and lower section 16 revolves around second pivotal means 32, but the pin 28 following the path of the slot 26 also controls the movement of extremity side 17 of lower section 16, therefore, the moving system has only one degree of freedom at the early stage; once the pin 28 leave the range of slot 26, lower section 16 can revolves with upper section 18 around second pivotal means 32 freely while upper section 18 revolves with roof 20 around first pivotal means 30, leading to a two degree of freedom for lower section 16, or lower section 16 can be locked with upper section 18 by a second locking means (not shown), and then lower section 16 bound together with upper section 18 are revolved around first pivotal means 30.
A first locking means 44 to lock lower section 16 and upper section 18 together when they are stretched, or not flipped with each other at all.
To a door with an adjustable glass 36, it can be connected by a third pivotal means 34 with an extension plate 38 with same radii of curvature and same center of adjustable glass 36. When the door is totally closed, adjustable glass 36 and extension plate 38 are locked together by a third locking means (not shown), and they can move together up and down along the path of glass rail 40. When a window regulator is actuated, it moves an driving media 42 up and down, which can also move along the bottom edge of extension plate 38, therefore, the usually circular movement of driving media 42 driven by the regulator can move the glass up and down.
For a door with an adjustable glass, the lower edge of upper section 18 is behind the upper edge of lower section 16, in other words, when the door is totally closed, the upper edge of lower section 16 is visible to a person outside the vehicle, while the lower edge of upper section 18 is not. Said first locking means 44 can not be released until adjustable glass 36 is totally raised up and third pivotal means 34 is concentric with second pivotal means 32. This characteristics prevents adjustable glass 36 from the risk of being broken when lower section 16 is flipped against upper section 18 of door 14 while the adjustable glass 36 is not raised up totally.

When lower section 16 is flipped against upper section 18, no damage would be caused by any interference.
For a conventional "sedan" car, which currently has two doors at a side, or a van currently having more than one door at one side, two or more doors at one side can be combined together, leading to a unified door with bigger longitude dimension. This unifying saves a lot of manufacturing cost and assembling cost and it provides a better characteristics for side impact of the vehicle.
To open the door, raise the adjustable glass 36 all way up; release all conventional door locks (not shown); raise the lower edge of lower section 16 while keeping pin 28 moving along slot 26 on lower section of A pillar 22 or C pillar 24 or another pillar of aperture surrounding member 12; when the pin 28 moves out of the path of slot 26, it is locked with upper section 18 by a second locking means, then swing lower section 16 and upper section 18 together around first pivotal means 30 to a desired position, and it is locked by a fourth locking means to keep it from dropping down to hurt any occupant.
In an emergency or other necessary situation, the door can be open in another way, which doesn't flip lower section 16 against upper section 18, but retreats pin 28 from the engagement with slot 26, then release all conventional door locks, and flip the whole door around first pivotal means 30.

To overcome the aforementioned drawbacks, the present invention is brought forth.
As shown in Fig. 1 through Fig. 3, a first pivotal means 30 connects an upper section 18 of a door 14 with a body 10, usually at a border area of a roof 20 of said body 10;
a second pivotal means connects a lower section 16 of door 14 with upper section 18, usually at a position close to the lowest visible edge of a glass mounted within upper section 18;
There is a pin 28 on a vertical edge side of lower section 16, said pin 28 being able to slide along a slot 26 on a vertical section of a pillar, when the door is just opened, upper section 18 revolves around a first pivotal means 30, and lower section 16 revolves around second pivotal means 32, but the pin 28 following the path of the slot 26 also controls the movement of extremity side 17 of lower section 16, therefore, the moving system has only one degree of freedom at the early stage; once the pin 28 leave the range of slot 26, lower section 16 can revolves with upper section 18 around second pivotal means 32 freely while upper section 18 revolves with roof 20 around first pivotal means 30, leading to a two degree of freedom for lower section 16, or lower section 16 can be locked with upper section 18 by a second locking means (not shown), and then lower section 16 bound together with upper section 18 are revolved around first pivotal means 30.
A first locking means 44 to lock lower section 16 and upper section 18 together when they are stretched, or not flipped with each other at all.
As shown in Fig. 5, to a door with an adjustable glass 36, it can be connected by a third pivotal means 34 with an extension plate 38 with same radii of curvature and same center of adjustable glass 36. When the door is totally closed, adjustable glass 36 and extension plate 38 are locked together by a third locking means (not shown), and they can move together up and down along the path of glass rail 40. When a window regulator is actuated, it moves an driving media 42 up and down, which can also move along the bottom edge of extension plate 38, therefore, the usually circular movement of driving media 42 driven by the regulator can move the glass up and down.
As shown in Fig. 5 and Fig. 8, for a door with an adjustable glass, the lower edge of upper section 18 is behind the upper edge of lower section 16, in other words, when the door is totally closed, the upper edge of lower section 16 is visible to a person outside the vehicle, while the Iower edge of upper section 18 is not. Said first locking means 44 can not be released until adjustable glass 36 is totally raised up and third pivotal means 34 is concentric with second pivotal means 32. This characteristics prevents adjustable glass 36 from the risk of being broken when lower section 16 is flipped against upper section 18 of door 14 while the adjustable glass 36 is not raised up totally.
As shown in Fig. 6, for a door with a stationary glass or plate 46, this situation being popular in a rear door of most vans and trucks, the upper edge of lower section 16 is behind the lower edge of upper section 18, and no any one of 34, 38 42 and 40 is needed. When lower section 16 is flipped against upper section 18, no damage would be caused by any interference.
For a conventional "sedan" car, which currently has two doors at a side, or a van currently having more than one door at one side, two or more doors at one side can be combined together, leading to a unified door with bigger longitude dimension. This unifying saves a lot of manufacturing cost and assembling cost and it provides a better characteristics for side impact of the vehicle.
To open the door, raise the adjustable glass 36 all way up (Fig. 4); release all conventional door locks (not shown); raise the lower edge of lower section 16 while keeping pin 28 moving along slot 26 on lower section of A pillar 22 or C pillar 24 or another pillar of aperture surrounding member 12; when the pin 28 moves out of the path of slot 26, it is locked with upper section 18 by a second locking means, then swing lower section 16 and upper section 18 together around first pivotal means 30 to a desired position, and it is locked by a fourth locking means to keep it from dropping down to hurt any occupant (Fig. 1 through Fig. 3).
In an emergency or other necessary situation, the door can be open in another way, which doesn't flip lower section 16 against upper section 18, but retreats pin 28 from the engagement with slot 26, then release all conventional door locks, and flip the whole door around first pivotal means 30 (Fig. 9}.
An elastic element, such as a spring, can be optionally add between any relevant moving part of present invention.
A damping element, such as a strut, can be optionally add between any relevant moving part of present invention.
A power driving means, such as a motor, can be optionally add between any relevant moving part of present invention.
