Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door stop holding device for holding a door of a box-type vehicle body at a predetermined opening.

[0002]

[Prior art]

 In the conventional door stop holding device disclosed in Japanese Utility Model Laid-Open No. 63-30564, a long groove and a locking hole located at one end of the long groove are provided in a restricting member fixed to the floor of a box-shaped vehicle body opening. A bent portion at one end of the arm member is pivotally attached to the inner surface of the door pivotally attached to the opening of the vehicle body by a pivoting member, and the bent portion at the other end of the arm member is engaged with the long groove of the regulating member. Then, when the door reaches a predetermined opening, the bent portion at the other end is fitted into the locking hole.

However, in this door stop / hold device, when the bent portion at the other end of the arm member is pulled out from the locking hole of the regulating member prior to the closing and rotation of the door, the door stop holding device pivots on the circumferential surface of each bent portion of the arm member. In order to prevent the edges of the support member and the restriction member from sticking to each other and stopping the movement, it is necessary to grasp the appropriate position of the arm member with one hand or both hands and lift it so as to move horizontally.

Further, since it is used outdoors, rusting of the arm member, the regulating member and the pivot member is unavoidable, but the increase of the sliding resistance due to the rusting further deteriorates the operability at the time of extraction. This increase in slip resistance prevents the arm member from moving downward by its own weight when the door is opened, preventing the bent part from automatically fitting into the locking hole, and pushing the arm member down by hand to fit it into the locking hole. Since it is necessary to fit them together, the operability at the time of fitting is not good.

Furthermore, in the conventional device, the restricting member is fixed to the floor of the opening, and when the door is opened and rotated by a certain angle or more, the arm member contacts the side pillar of the opening. To fully open the door to 180 or 279 degrees for convenient loading and unloading, it is necessary to grab the arm member and pull it out from the long groove of the regulating member, and then close the door after the work. When doing so, it is necessary to manually re-engage the bent end of the arm member with the long groove in the middle thereof, and the operability at the time of full open use is not good.

[0006]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a door stop holding device which is always easy to operate regardless of whether it is used at a predetermined opening or when it is fully opened.

[0007]

[Means for Solving the Problems]

 Referring to the reference numerals in the accompanying drawings, the door stop holding device of the present invention includes a base end portion 5 of an arm rod 4 on an inner side surface 2 of an opening of a fixed frame body 1 by means of a pivot member 3. The contact plate 9 is pivotally attached and fixed to the inner surface 8 of the door 7 attached to the fixed frame 1 by the hinge 6, and the front hook 10 of the arm rod 4 is arranged so as to be in sliding contact with the front surface 10 of the contact plate 9. The guide case 12 with which the tip hook bar 11 of the arm bar 4 is slidably contacted is fixed to the inner surface 8 of the door 7 so as to be adjacent to the contact plate 9, and the guide case 12 of the front plate portion 13 of the guide case 12 closer to the pivotal support member 3 is A slant wall plate portion 14 that is in contact with or close to the inner side surface 8 of the door 7 is continuously provided at the side edge portion.

The front plate 13 of the guide case 12 is provided with a notch 15 at a side edge of the front plate 13 farther from the pivotal support member 3 to engage and disengage the tip hook 11 of the arm rod 4, and a shutter plate for closing the notch 15. 16 is housed in the guide case 12, and the side wall of the shutter plate 16 farther than the pivot member 3 is provided with a slanted wall plate part 17 that is in contact with or close to the front face 10 of the backing plate 9. 16 is urged to slide in the transverse direction of the contact plate 9 by the spring 18, and the arm rod 4 is rotationally urged by the spring 19 in the direction in which the tip hook portion 11 comes into contact with the contact plate 9 and the guide case 12. The pulling member 20 is connected to 16.

[0009]

[Action]

 When the door 7 is opened and rotated about the hinge 6, the arm bar 4 is rotated about the pivot member 3 in the same direction as the door 7, and the arm bar is pressed against the front surface 10 of the backing plate 9 by the spring 19. The front end hook portion 11 of No. 4 approaches the guide case 12 while slidingly contacting the front surface 10 of the contact plate 9. When the pulling member 20 is pulled downward and the shutter plate 16 is retracted from the contact plate 9 at the beginning or in the middle of this opening rotation, the tip of the arm rod 4 and the hook rod 11 are notched 15 in the front plate portion 13 of the guide case 12. Automatically engages. As a result, the door 7 is stopped and held at the opening.

When the door 7 is closed and rotated around the hinge 6 after carrying in and out the luggage, the arm rod 4 rotates in the same direction as the door 7 around the pivot member 3, and the tip hook of the arm rod 4 is rotated. The portion 11 automatically separates from the notch 15 of the guide case 12, and slides to the tip side of the contact plate 9. Immediately after the tip hook portion 11 has escaped from the guide case 12, the shutter plate 16 comes to a position where the swash wall plate portion 17 abuts or approaches the front surface 10 of the contact plate 9.

When the shutter plate 16 is in the state where the notch 15 is closed as described above, when the door 7 is opened and rotated, the front face 10 of the contact plate 9 comes into sliding contact with the guide case 12 from the tip end side. The front end hook portion 11 of the arm rod 4 is guided by the slant wall plate portion 17 of the shutter plate 16 and automatically rides on the front plate portion 13 of the guide case 12, and is abutted via the slant wall plate portion 14 of the guide case 12. The base end of the plate 9 and the inner side surface 8 of the door 7 are slidably contacted. As a result, the door 7 is fully opened.

When the door 7 is closed and rotated, the end hook portion 11 of the arm rod 4 is guided by the slanted wall plate portion 14 of the guide case 12 and automatically rides on the guide case 12, and the front plate portion 13 and the shutter plate. It slides on the front surface 10 of the backing plate 9 through the slant wall plate portion 17 of 16 and moves to the tip end side of the backing plate 9.

[0013]
