Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a latching device for locking a closed door to a fixed frame body, which is used for equipment fixed to a hull such as a yacht or for luggage storage. It is a thing.

[Prior Art] In a generally used latch device, a base end portion of a latch plate is pivotally attached to a front surface side of an attachment substrate fixed to a door by a shaft body,
The receiving body is pivotally attached to the front surface side of the fixed substrate fixed to the fixed frame body by the shaft body, the through hole is provided in the latch plate from which the receiving body is fitted from the rear surface side, and after passing through the through hole, The receiving body is rotated so that the jaw of the receiving body is engaged with the front side of the latch plate.

For small boats such as yachts that are exposed to severe waves,
Since external forces and vibrations are repeatedly received from all directions of up, down, left, right, front and back, the fixing position of the mounting substrate with respect to the fixed frame body may be distorted after long-term use. Further, when the packing or gasket mounted between the fixed frame body and the door is deteriorated due to the influence of salt or the like and the cross-sectional dimension is reduced, the hermeticity is reduced or a gap is generated.

However, in the conventional device, the shaft body for pivotally attaching the latch plate to the mounting substrate is directly attached to the latch plate, and the distance between the pivot shaft and the receiving hole at the tip of the latch plate is fixed, and any increase or decrease is changed. Since it is not possible to compensate for the deviation of the fixing position of the mounting substrate with respect to the fixed frame, it is also possible to correct the relative position of the receiver and the latch plate in response to the reduction in cross-sectional dimension due to deterioration of packing and gasket. It is also impossible to absorb the generation of gaps.

[Problems to be solved by the invention] Therefore, the object of the present invention is to easily correct and correct the deviation of the fixing position of the mounting substrate due to vibration or the like, and to reduce the cross-sectional dimension due to deterioration of the packing or gasket.
An object of the present invention is to provide a seismic-resistant latching device that corrects the relative positions of the metal receiving member and the latching plate to properly absorb the occurrence of a gap.
