Flap locking device

Abstract

A slider advancing / retracting to / from a tongue piece receiving part is fitted and supported by a guide part of a base, a base end of a lever handle is pivotably supported by a first horizontal shaft on a lower side of the slider, and a base end of a holding arm with a tip part attached / detached to / from the tongue piece receiving part is pivotably supported by a second horizontal shaft on the upperside of the slider. By obliquely erecting and turning the holding arm via the lever handle at the elevated position where the slide is advanced toward the tongue piece receiving part, the restrictionof the locking tongue piece by the tip of the holding arm is released, and the slider is evacuated to the lowered position while the holding arm is retained in the restriction releasing posture. Thepresent invention provides a wing lock device applicable to various kinds of wing type cargo trucks having different radii of rotation of the wing, and capable of correctly pressing and restraining alocking tongue piece even when the wing and the locking tongue piece are distorted and deformed.

Description

technical field [0001] The present invention relates to a flap locking device mounted on a side panel in order to stably bind the flap in a closed position in a winged van having a flap that can open and close a cargo box from above. Background technique [0002] figure 1 The illustrated wing-shaped van 100 includes: a base 102 supported by a predetermined number of wheels 101; side panels 103 arranged on the left and right sides and the rear side of the base 102; and sandwiching each side panel 103 The door-shaped parts 104 erected on the front and rear ends of the base 102; the erection parts 107 erected between the tops of these door-shaped parts 104. The gate member 104 is composed of a pair of left and right pillars 105 and beam members 106 between the tops of the pillars 105 , and a bridging member 107 is connected between the central portions of the beam members 106 in the front-rear direction. [0003] The left and right pair of wings 108 are composed of a roof win...

AI Technical Summary

Problems solved by technology

[0016] As described above, the flap locking device of the pressing member rotation method allows the flaps to be released and rotated when the pressing member rises and rotates at a certain inclination angle with respect to the base plate to assume a retreat posture. The radius of rotation differs depending on the type of vehicle. When the fixed position of the base plate relative to the side plate is not properly selected, the pressing member cannot sufficiently retract and move to the position that must be reached. When the flap is opened and rotated, the snap lock The tongue sometimes collides with and interferes with the above-mentioned pressing parts

[0017] When the fixing position of the above-mentioned base plate relative to the above-mentioned side plate is excessively lowered downwards in order to avoid this kind of interference, then the overlapping dimension of the above-mentioned pressing member and the above-mentioned buckle tongue piece is shortened, so that the above-mentioned press member is pressed against the above-mentioned buckle tongue piece. Press-to-bind effect of

[0018] In addition, as mentioned above, in the flap locking device of the pressing member sliding method, if the flap or the buckle tongue piece is bent and deformed for some reason during use, when the flap is closed, there may be a problem. The lower end of the above-mentioned buckle tongue piece is not arranged in the normal position and appears to float up. In this floating state, when the above-mentioned pressing member slides upward, the above-mentioned pressing member cannot advance to the Normal position, the above-mentioned pressing part cannot press and restrain the above-mentioned buckle tongue
