Description

  The present invention relates to a door check device that regulates (selects) the opening degree of a vehicle door.

As a door check device that regulates the maximum opening when a vehicle door is opened, a device that can select a maximum opening and an intermediate opening (half-open) is known. When half-open is selected, some operating member is operated to restrict the maximum opening to half-open.
JP 2004-52404 A

  However, in the conventional apparatus, there is an inconvenience that the operation of selecting half-opening must be performed with the door closed.

  An object of the present invention is to provide a door check device that can perform a half-open selection operation regardless of whether the door is open or closed.

  The present invention relates to a check arm that is pivotally attached to a vehicle body and extends into a door body that is opened and closed; and an opening degree of the door body that is selectively engaged with a stopper provided in the check arm and located in the door body. An intermediate stopper mechanism that regulates the intermediate opening to an intermediate opening; and the intermediate stopper mechanism is moved between the intermediate stop position and the non-stop position by the operation mechanism, and when in the non-stop position, the door body An intermediate stopper lever that does not engage with the check arm stopper when the door is opened and closed; when the intermediate stopper lever is in the intermediate stop position and the door body is opened from the fully closed position, it engages with the check arm stopper to A stopper surface formed on the intermediate stopper lever that restricts the opening to a half-open position; this intermediate stopper lever is at the intermediate stop position; It is characterized by having; once moving nonstop position side stopper lever between intermediate the check arm of the stopper when the door body is closed from the fully open position, and an open guide surface formed on the intermediate stopper lever Te.

  It is preferable to provide a pair of intermediate stopper levers symmetrically.

  When the intermediate stopper lever is at the intermediate stop position, it is preferable that the intermediate stopper lever is always urged to rotate in the intermediate stop direction.

  It is practical to provide the door body with a friction shoe that provides a relative sliding resistance with the check arm and a stopper portion that engages with a stopper of the check arm to regulate the maximum opening of the door body.

  According to the door check device of the present invention, it is easy to use because it can be set half open regardless of the opening of the door.

  FIG. 1 shows a planar positional relationship between the check arm 11 pivotally attached to the vehicle body 10 and the door body 20 of the intermediate stopper mechanism 30 provided in the door body 20 at each opening degree. One end of the check arm 11 is pivotally attached to the pillar 13 of the vehicle body 10 with a shaft 12, and the other end extends into the door body 20. A stopper pin 14 is fixed to the distal end portion (free end portion) of the check arm 11 that is always located in the door body 20 regardless of the opening degree of the door body 20. The intermediate stopper mechanism 30 moves relative to the check arm 11 that swings around the shaft 12 as the door body 20 is opened and closed, and is provided at a fixed position in the door body 20. Further, in the door body 20, a fully open stopper friction shoe 21 that is also relatively moved relative to the check arm 11 is fixed on the side closer to the shaft 12 than the intermediate stopper mechanism 30. The check arm 11, the fully open stopper friction shoe 21 and the intermediate stopper mechanism 30 change the relative positions depending on the opening degree of the door body 20. In FIG. 1, the fully closed position and the fully open position of the door body 20 of these elements are shown. The position and the position at the half-open position are indicated by a solid line, a broken line, and a one-dot chain line, respectively.

  The fully-open stopper friction shoe 21 is a well-known element that provides sliding resistance when moving relative to the check arm 11 and restricts the fully-open position. That is, the fully open stopper friction shoe 21 gives sliding resistance to the check arm 11 when the door body 20 is opened and closed, and abuts against the stopper pin 14 to restrict its fully open position (broken line in FIG. 1).

  When the intermediate stopper mechanism 30 is operated by the operation mechanism, the intermediate stopper mechanism 30 engages with the stopper pin 14 of the check arm 11 to restrict the opening of the door body 20 to half open. As shown in FIGS. 2 and 3, the intermediate stopper mechanism 30 is positioned above and below the relative path of the check arm 11 in the door body 20, and is paired symmetrically with a pair of fixed shafts 31. An intermediate stopper lever 32 having a shape is provided. Each intermediate stopper lever 32 has a working arm 32a extending from the fixed shaft 31 to the relative path side of the check arm 11 (stopper pin 14), and an operating arm 32b extending from the fixed shaft 31 in the opposite direction of the working arm 32a. ing.

  Each operation arm 32 b is formed with a long hole 33 extending in the radial direction from the fixed shaft 31, and an operation pin 34 is fitted in a portion where the long hole 33 overlaps. The operation pin 34 is guided so as to be movable in an extension direction of the relative traveling direction of the check arm 11, and is coupled to the operation mechanism 22 provided in the door body 20 or the vehicle body 10. Thus, it is possible to move between the intermediate stop position (FIG. 2 (A)) and the non-stop position ((B)).

  The operating arms 32a of the pair of intermediate stopper levers 32 are positioned at an intermediate stop position (FIG. 2A) approaching each other when the operation pin 34 is at the intermediate stop position, and when the operation pin 34 is at the non-stop position. They are located at non-stop positions (same (B)) that are separated from each other. When the pair of working arms 32a are in the non-stop position, the working arm 32a and the stopper pin 14 of the check arm 11 do not interfere, and the door body 20 can freely open and close between the fully open position and the fully closed position.

  The pair of working arms 32a are formed with a stopper surface 35 that engages with the stopper pin 14 of the check arm 11 and an open guide surface 36 when the intermediate stopper lever 32 is in the intermediate stop position.

  An urging direction reversing tension spring 37 is stretched between the pair of intermediate stopper levers 32. When the pair of intermediate stopper levers 32 are in the intermediate stopper position, the urging direction reversing tension spring 37 urges the working arms 32a of the levers 32 to approach each other, and when in the non-stop position, The acting arms 32a are urged to rotate in directions away from each other. That is, the biasing direction reversing tension spring 37 reverses the biasing direction of the pair of intermediate stopper levers 32 depending on which of the straight lines connecting the upper and lower fixed shafts 31 is located.

  The stopper surface 35 is configured by an inner wall at one end of a through hole 35a formed in the working arm 32a. The stopper pin 14 of the check arm 11 enters the inner part between the pair of intermediate stopper levers 32 (the side closer to the operation pin 34) when the door body 20 is in the fully closed position (solid line in FIG. 1). When 32 is in the intermediate stopper position and the door body 20 is opened from the fully closed position, the stopper pin 14 abuts against the stopper surface 35 to restrict the opening of the door body 20 to half open (FIG. 2A). FIG. 1 one-dot chain line).

  The opening guide surface 36 is in contact with the stopper pin 14 of the check arm 11 when the intermediate stopper lever 32 is in the intermediate stop position and the door body 20 is closed from the fully open position (position opened from the half-open position). The stopper lever 32 is temporarily rotated to the non-stop position side. When the stopper pin 14 exceeds the stopper surface 35 (enters the through hole 35a), the intermediate stopper lever 32 returns to the intermediate stop position by the force of the biasing direction reversing tension spring 37.

  Therefore, the door check device having the above configuration can set the half-open restriction regardless of the opening degree of the door body 20. First, when the door body 20 is in the fully closed state, the half open state can be set via the operation mechanism 22 without any problem. On the other hand, when the half-open restriction is set by the operation mechanism 22 when the door body 20 is at the fully open position (position opened from the half-open position), the intermediate stopper lever 32 moves to the intermediate stop position via the operation pin 34. In this state, when the door body 20 is closed from the fully open position, the opening guide surface 36 of the intermediate stopper lever 32 contacts the stopper pin 14 of the check arm 11 and once rotates to the non-stop position side. After passing through the opening guide surface 36, it returns to the intermediate stop position. Therefore, even when the door body 20 is in the fully open position (position opened from the half open position), the half open restriction can be set.

  In the above embodiment, a pair of intermediate stopper levers 32 are provided, but only one mechanism is established. Further, although the intermediate stopper lever 32 is of a type that rotates around the fixed shaft 31, it may be of a straight movement type.

  In the above embodiment, the single check arm 11 is shared by the full-open stopper by the full-open stopper friction shoe 21 and the intermediate stopper by the intermediate stopper mechanism 30, but for the full-open stopper (friction shoe) and the intermediate stopper. Separate check arms may be provided.

It is a top view which shows one Embodiment of the door check apparatus of this invention. FIG. 2 is a view taken in the direction of arrow II in FIG. 1, and (A) and (B) depict different states. It is a partial enlarged view of an intermediate stopper lever.
