  The present invention relates to a wing holder for holding a wing in a closed state, and more particularly to a wing holder for holding a wing of a van type truck in a closed state.

  As a means for opening and closing a storage device for storing articles, there is a “wing” that opens and closes so that a bird's feather flutters. Such a wing is provided on the loading platform so as to open and close in the vertical direction at the side of the truck, for example, as a means for opening and closing a cargo box of a van type truck.

  In Patent Document 1, “a wing lock for holding a wing that is rotated and opened in a closed state is pivotally supported on the base side, and approaches or separates from the base side by an operation. The handle member pivots in the direction opposite to the pivot direction of the handle member upon receiving the biasing force from the handle member as the handle member pivots. And a stopper member that pivots so as to approach or separate from the wing, and an intermediate portion of the stopper member intersects with or is engaged with an intermediate portion of the handle member, and the stopper member is Energized from the handle member at the intermediate portion, the end of the stopper member is locked at an initial position close to the wing to prevent the opening of the wing, and by pivoting the handle member in one direction, The initial position The wing can be released by separating from the wing, and when the handle member is pivoted in the other direction, the handle member is biased toward the initial position and pivoted in the initial position direction. A wing lock characterized by moving "has been proposed.

  FIG. 1 is an operation diagram of a conventional wing holder related to the above-described wing lock.

  Referring to FIG. 1, a wing holder according to a conventional example includes a handle 4 pivotally supported by a base plate 2 on the base (anchor 1) side, a stopper 3 pivotally supported by the base plate 2 and holding the wing W in a closed state. The intermediate portion of the stopper 3 intersects with or is engaged with the intermediate portion of the handle 4, and the sliding portion 6 formed in the intermediate portion that can intersect the handle 4 in the stopper 3, and the stopper in the handle 4 3 has a contact surface 17 formed at an intermediate portion capable of intersecting with 3, and the contact surface 17 is a surface parallel to the handle 4 axis direction. The length L1 of the contact surface 17 is the same as the length of the window 8. The length L <b> 1 of the contact surface 17 is sufficiently long so that the stopper 3 pivots between the closed position and the maximum opening degree α, and the sliding portion 6 slides within the window 8.

Japanese Patent No. 3523029 (Claim 1)

  When the wing W is held by operating the handle 4 and closing the stopper 3 in the wing holder, the sliding portion 6 on the stopper 3 side is connected to the handle on the handle 4 side in the engaging portion between the stopper 3 and the handle 4. Necessary to contact the contact surface 17 parallel to the axial direction in a substantially perpendicular direction, the frictional force acting between them increases and the stopper 3 does not rotate smoothly or is pushed to push the stopper 3 toward the closed position. However, there is a problem that the operating force of the handle 4 increases.

  In the above case, the contact surface 17 is worn or scraped over time. As a result, the direction of the rotational force that the handle 4 acts on the stopper 3 and the axial direction of the stopper 3 (the normal direction of the contact portion (surface)) ) Are substantially the same, the frictional force is further increased, and the rotational force acting on the stopper 3 may be lost to the frictional force between the stopper 3 and the handle 4.

  An object of the present invention is to provide a wing holder that can be operated with a small force when holding a wing by operating the handle and closing the stopper, and the durability of the portion where the handle and the stopper engage or slide is improved.
