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.

[0011]

[Action]

 When the door 7 is opened and rotated about the hinge 6, the arm rod 4 is rotated about the pivot member 3 in the same direction as the door 7, and the arm rod pressed against the front surface 10 of the backing plate 9 by the spring 20. 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. The tip hook portion 11 automatically guided up to the front plate portion 13 of the guide case 12 by being guided by the slant wall plate portion 17 is finally automatically engaged with the vertical groove portion 15 in the central portion of the front plate portion 13. As a result, the door 7 is stopped and held when it has rotated by a predetermined opening degree, for example, 90 degrees.

When the pulling member 21 is pulled and the slider plate 16 is lowered after the work of loading and unloading luggage, the sloped cam plate portion 18 of the slider plate 16 pushes the tip hook portion 11 out of the vertical groove portion 15, and the stopper plate portion 31. When the door 7 is closed and rotated about the hinge 6, the arm rod 4 rotates about the pivot member 3 in the same direction as the door 7, so that the front hook portion. 11 slides from the front plate portion 13 of the guide case 12 through the slanted wall plate portion 17 to the tip end side of the contact plate 9, and the door 7 is fully closed. When the tip hook portion 11 passes through the guide case 12 and the hand is released from the pulling member 21, the biasing force of the spring 19 causes the inclined cam plate portion 18 and the stopper plate portion 31 of the slider plate 16 to escape from the vertical groove portion 15. It will slide to the waiting position.

When the door 7 is fully opened beyond 90 degrees, the pulling member 21 is pulled to lower the slider plate 16, and the inclined cam plate portion 18 and the stopper plate portion 31 of the slider plate 16 are connected to the vertical groove portion of the guide case 12. Fit to 15. When the door 7 is opened and rotated about the hinge 6 in this state, the arm rod 4 rotates about the pivot member 3 in the same direction as the door 7, and the swash wall plate portion 17 to the front plate portion of the guide case 12. The tip hook portion 11 that automatically climbs up to 13 is automatically transferred to the front plate portion 13 on the other side without entering the vertical groove portion 15, and passes through the sloping wall plate portion 14 on the other side to move the door 7 of the door 7. The inner surface 8 is slidably contacted with the base end side. As a result, the door 7 is fully opened at an angle of 90 degrees or more. When the tip hook portion 11 passes through the guide case 12 and the hand is released from the pulling member 21, the slidable cam plate portion 18 and the stopper plate portion 31 of the slider plate 16 escape from the vertical groove portion 15 by the bias of the spring 19. Slide to the standby position.

When closing the door 7, the pulling member 21 is pulled to lower the slider plate 16, and the inclined cam plate portion 18 and the plug plate portion 31 of the slider plate 16 are fitted into the vertical groove portion 15 of the guide case 12. . When the door 7 is closed and rotated about the hinge 6 in this state, the arm rod 4 rotates about the pivot member 3 in the same direction as the door 7, and the slant wall plate portion 14 automatically moves to the front plate portion 13. The tip hook portion 11 that has climbed up to the front side automatically moves to the front plate portion 13 on the other side without entering the vertical groove portion 15, and passes through the swash wall plate portion 17 on the other side to the tip portion side of the backing plate 9. Slide into contact with. As a result, the door 7 is fully closed. When the tip hook portion 11 passes the guide case 12 and the hand is released from the pulling member 21, the slider plate 16 waits for the sloped cam plate portion 18 and the plug plate portion 31 to escape from the vertical groove portion 15 by the bias of the spring 19. Slide into position.

In another mode, the door stop holding device pulls the pulling member 21 to open the lower stopper plate portion 31 from the vertical groove portion 15 while opening it at a predetermined opening degree, for example, 90 degrees, while the slope cam The slider plate 16 is slid to a position where the plate portion 18 and the upper stopper plate portion 31 do not fit into the vertical groove portion 15. The tip hook portion 11 of the arm rod 4 automatically guided up from the backing plate 9 to the front wall plate portion 13 by the slant wall plate portion 17 automatically engages with the vertical groove portion 15, and the door 7 is opened. Hold on to stop. When the hand is released from the pulling member 21, the stopper plate portion 32 of the slider iterator 16 comes into contact with the tip end surface of the tip hook portion 11.

When the door 7 is opened beyond the predetermined opening, the door 7 is opened and rotated about the hinge 6 without pulling the pulling member 21. The arm rod 4 rotates around the pivot member 3 in the same direction as the door 7, and the tip hook portion 11 that automatically climbs up from the swash wall plate portion 17 to the front plate portion 13 of the guide case 12 has a slider plate 16 Since it is obstructed by the plug plate part 31 on the lower side of the door 7, it automatically transfers to the front plate part 13 on the other side without entering the vertical groove part 15, and then passes through the swash wall plate part 14 on the other side to remove the inside of the door 7. The side surface 8 is slidably contacted with the base end side. As a result, the door 7 is fully opened at an angle of 90 degrees or more.
