JPH10102880A - Biaxial joint for car - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simplify constitution, machining and assembly, to prevent even the formation of a sliding section, by which a film is peeled, to lock one of two shafts or bring it to a free state selectively and surely in response to the opening and closing of a door and to open and close the door smoothly. SOLUTION: The biaxial joint for the car is constituted so that each free end of mounting members to a car body and a door is combined at both ends of a connecting member by hinges. Stoppers 16, 17 are installed to both hinge couplings respectively, one end of a seesaw member 18, in which an intermediate section is supported rotatably to the connecting member, is disposed so as to be able to be selectively engaged at all times, the seesaw member 18 is changed over in response to the rotation of the door and engaged with either of the stoppers 16, 17, and a locking control member 19 is mounted at that time. Stoppers are set up to a car-body side pin and a door-side pin configuring both hinge couplings respectively, one end of the seesaw member 18, in which the intermediate section is supported pivotally to the connecting member, is arranged so as to be able to be selectively engaged at all time, and a control cam member changing over and interlinking the seesaw member 18 to one of the stoppers in response to the revolution of the door is fitted to the car-body side pin.

が形成されている。2. Description of the Related Art It is desirable that the double door is opened until it is parallel to the vehicle body, that is, at least 270 degrees, so as not to hinder cargo handling operations and pedestrians. However, if the door is supported on the vehicle body with a one-shaft joint (hinge), a large rotation range cannot be usually obtained, so that the door is connected with a two-shaft joint. Conventionally used biaxial joints that open at 270 degrees include those shown in FIGS. This is a vehicle-side stopper 3 and a door-side stopper 4 fixed to the vehicle body 1 and the door 2, respectively.
Are connected to the first pin 5 and the second pin 6 inserted through the stoppers 3 and 4 at a predetermined distance by connecting members 7 and 7 ′ fitted to the pins from above and below, respectively.
A slider 8 is provided to move between the cams 4a and 4a.

なる。In the above-mentioned two-shaft joint, when the door 2 is opened in the direction of the arrow from the closed state shown in FIG. 15, it rotates about the first pin 5 and passes through the 90-degree opened position in FIG. When the door 2 is rotated by 180 degrees as described above, one end of the slider 8 faces the cam 3a of the vehicle body side stopper 3. As a result, when the door 2 is further turned around the second pin 6 in the direction of the arrow, one end of the slider 8 is pushed at the other end by the outer periphery of the door-side stopper 4 as shown in FIG. 3 comes into contact with the cam 3a, and the door 2 is parallel to the vehicle body 1.

Not only will the painted coating peel off and become ugly,
There is a disadvantage that the peeling of the coating film rusts and the operation is not smooth.

る。According to the present invention, there is provided a biaxial joint for a vehicle in which each free end of a member to be attached to a vehicle body and a door is hinged to both ends of a connecting member. Along with disposing so that one end of the seesaw member pivotally supporting the middle can always be selectively engaged,
A first invention in which a control member for switching the seesaw member in accordance with the rotation of the door to engage with one of the stoppers and lock the same is provided, and constitutes the two hinge connection in the biaxial joint for a vehicle. A stopper is provided on each of the vehicle body-side pin and the door-side pin, and one end of a seesaw member having a middle shaft is supported by the connecting member so that the one end can be always engaged with the connection member. A second invention in which a control cam member for switching and engaging the seesaw member with one of the stoppers in accordance with movement is provided, and a stopper is provided in each of the two hinge connection portions of the two-shaft joint, and the connection is performed. An end of a seesaw member having a middle shaft supported on the member is disposed so as to be always able to be selectively engaged, and the seesaw member is connected between the vehicle body mounting member and the connecting member in accordance with the rotation of the door. Because comprising a third invention provided with the engagement allowed to control the band member is switched to one of the stopper,
It has a simple structure, is easy to process and assemble, and has no part that slides with a strong force, so that the coating film does not peel off and does not become ugly. Further, the seesaw member engaged with the stopper can be selectively and reliably locked or free of one of the two shafts in accordance with the opening and closing of the door by the control member, so that the door can be smoothly opened and closed. According to the third aspect of the present invention, since the control members are the control cam and the control band, respectively, there is an effect that the production is particularly easy, the material cost is low, and the operation is reliable.
