Abstract

Official abstract text for this publication.

A personal watercraft includes a ship body, a luggage compartment provided in the ship body and provided with an opening for taking in and out luggage, a hatch attached to the ship body and capable of opening and closing the opening, and a lock mechanism for fixing the hatch to the ship body in a state where the opening is closed. The lock mechanism includes a plurality of lock portions that engage the hatch and the ship body with each other, one operation lever that causes the plurality of lock portions to unlock the engagement in an interlocking manner, and a transmission member that transmits an operation action of the operation lever to at least one of the plurality of lock portions to unlock the engagement of the lock portion.

First claim

Opening claim text (preview).

What is claimed is: 1 . A personal watercraft comprising: a ship body; a luggage compartment in the ship body and including an opening for taking in and out luggage; a hatch attached to the ship body and capable of opening and closing the opening; and a lock mechanism that fixes the hatch to the ship body in a state where the opening is closed, wherein the lock mechanism includes: a plurality of lock portions that provide a corresponding plurality of engagements of the hatch and the ship body with each other, a single operation lever that causes the plurality of lock portions to unlock the corresponding plurality of engagements in an interlocking manner, and a transmission member that transmits an operation action of the single operation lever to the plurality of lock portions to unlock the corresponding plurality of engagements of the lock portions to enable opening of the hatch. 2 . The personal watercraft according to claim 1 , wherein: the plurality of portions leeks include: a first lock portion in which the corresponding engagement is unlocked by operation of the single operation lever, and a second lock portion disposed at a position separated from the first lock portion, the transmission member transmits, to the second lock portion, an operation action of the single operation lever for unlocking engagement of the first lock portion. 3 . A personal watercraft, comprising: a ship body; a luggage compartment in the ship body and including an opening for taking in and out luggage; a hatch attached to the ship body and capable of opening and closing the opening; and a lock mechanism that fixes the hatch to the ship body in a state where the opening is closed, wherein the lock mechanism includes: a plurality of lock portions to have an engagement of the hatch and the ship body with each other, a single operation lever that causes the plurality of lock portions to unlock the engagement in an interlocking manner, and a transmission member that transmits an operation action of the single operation lever to the plurality of lock portions to unlock the engagement of the lock portions to enable opening of the hatch, wherein: the hatch includes an inner member opposing the opening, an outer member attached to the inner member, and an internal space defined by the inner member and the outer member, and the transmission member is disposed in the internal space. 4 . The personal watercraft according to claim 1 , wherein: the ship body includes a hull and a deck covering an upper surface of the hull, and the opening of the luggage compartment is disposed in a front portion of the deck. 5 . The personal watercraft according to claim 4 , wherein: the hatch includes a coupling portion to be coupled with the deck. 6 . The personal watercraft according to claim 5 , wherein: when a direction passing through a center of the opening in plan view and extending in a discretionary horizontal direction is a first direction, the coupling portion is disposed on one end side of the opening in the first direction, and the plurality of lock portions include: an end lock portion disposed on another end side of the opening in the first direction, and intermediate lock portions disposed at both ends of the opening in a second direction when a direction passing through a center of the opening in plan view and orthogonal to the first direction is the second direction. 7 . The personal watercraft according to claim 5 , wherein: the coupling portion is disposed on a front side or a rear side of the opening, and the plurality of lock portions include an end lock portion disposed on an opposite side of the coupling portion across the opening, and an intermediate lock portion disposed between the coupling portion and the end lock portion. 8 . The personal watercraft according to claim 7 , wherein: the opening is disposed in a central region in a width direction of a front portion of the deck, the coupling portion is disposed on a front side of the opening, at a position corresponding to a center in the width direction of the opening, and the intermediate lock portion is disposed on each of a left side and a right side of the opening. 9 . The personal watercraft according to claim 5 , wherein: the coupling portion and the plurality of lock portions are disposed so as to surround a periphery of the opening. 10 . The personal watercraft according to claim 5 , wherein: the coupling portion and the plurality of lock portions are disposed at positions adjacent to a periphery of the opening. 11 . The personal watercraft according to claim 1 , wherein: the plurality of lock portions include a plurality of types of lock portions having different forms of the engagement. 12 . The personal watercraft according to claim 2 , wherein: the second lock portion includes an engaged rod in the ship body and an engagement member in the hatch and engageable with the engaged rod, the engagement member includes an upper portion including a pivot shaft for pivoting the engagement member, and a lower portion including a hook that engages with the engaged rod so as to hold the engaged rod by pivot of the engagement member about the pivot shaft, and a shaft center of the engaged rod is disposed downstream relative to a virtual line extending vertically downward from the pivot shaft in a pivot direction when the engagement member unlocks engagement with the engaged rod. 13 . The personal watercraft according to claim 1 , wherein the transmission member includes: a displacement member, a main transmission member that transmits an operation force of the single operation lever to the displacement member to displace the displacement member, and a distribution transmission member that transmits a displacement force of the displacement member to the plurality of lock portions as power for the unlock. 14 . A personal watercraft, comprising: a ship body; a luggage compartment in the ship body and including an opening for taking in and out luggage; a hatch attached to the ship body and capable of opening and closing the opening; and a lock mechanism that fixes the hatch to the ship body in a state where the opening is closed, wherein the lock mechanism includes: a plurality of lock portions to have an engagement of the hatch and the ship body with each other, a single operation lever that causes the plurality of lock portions to unlock the engagement in an interlocking manner, and a transmission member that transmits an operation action of the single operation lever to the plurality of lock portions to unlock the engagement of the lock portions to enable opening of the hatch, the transmission member including: a displacement member, a main transmission member that transmits an operation force of the single operation lever to the displacement member to displace the displacement member, and a distribution transmission member that transmits a displacement force of the displacement member to the plurality of lock portions as power for the unlock, and wherein at least one of the main transmission member and the distribution transmission member includes a wire. 15 . The personal watercraft according to claim 13 , wherein: at least one of the main transmission member and the distribution transmission member includes a link rod. 16 . The personal watercraft according to claim 1 , wherein: the single operation lever consists of a single, unitary member, that causes the plurality of lock portions to unlock the corresponding plurality of e
