Description

  The present invention relates to a windscreen device for a motorcycle including a windscreen held by a vehicle body.

  The windscreen of a motorcycle is used to minimize rider fatigue due to exposure to the driving wind during long-distance travel on an expressway and shields the rider (especially the upper body) from the driving wind. On the other hand, many riders prefer not to use a windscreen for short-distance travel and low-speed urban travel.

  Therefore, a windscreen device for a motorcycle in which a windscreen can be attached to and detached from a vehicle body without using a tool is known (see, for example, Patent Documents 1 and 2).

JP-A-8-268365 JP 2004-161069 A

  The windscreen devices for motorcycles described in Patent Document 1 and Patent Document 2 each include a detachable windscreen held by a vehicle body (more specifically, a front fork). These conventional motorcycle windscreen devices include shaft members (bush or damper members) provided on the left and right sides of the vehicle body, and recesses (sockets or stopper members) hooked on the shaft members. A conventional windscreen device hooks a concave portion on a shaft portion and rotates the windscreen around the shaft portion to move to a fixed position (for example, see Patent Document 1), or rotates the windscreen around the shaft portion. Then, the lock mechanism is locked while adjusting the position (see, for example, Patent Document 2), and the installation of the wind screen is completed. On the other hand, in the conventional windscreen device, the windscreen is rotated around the shaft portion and moved to the disengagement position (see, for example, Patent Document 1), or the lock mechanism is unlocked while the windscreen is held by the shaft portion. (See, for example, Patent Document 2), the removal of the wind screen is completed.

  A conventional wind screen device having such a wind screen attaching / detaching process is such that a windscreen attaching / detaching operator (usually a rider) unintentionally or carelessly removes his / her hand from the wind screen, and the wind screen is focused on the shaft. May rotate and fall off. When there is only one operator who attaches / detaches the windscreen, such a risk of dropping gives an excessive psychological pressure to the operator and obstructs easy attachment / detachment of the windscreen.

  In addition, in the case of a conventional wind screen device, if the wind screen is not sufficiently locked at the fixed position (forgotten to lock), the wind screen may drop due to wind pressure or inertial force applied to the wind screen during traveling. There is also.

  Accordingly, the present invention provides a windscreen device for a motorcycle that can hold the windscreen on the main body even in an unlocked state and prevent it from falling off without impairing the ease of attaching and detaching the windscreen even in one-person work. Propose.

  In order to solve the above-described problems, a windscreen device for a motorcycle according to the present invention includes a vehicle body, a windscreen that covers a part of the front of the vehicle body, and a difference provided on one of the vehicle body and the windscreen. An insertion recess, and an insertion projection provided on the other of the vehicle body and the windscreen and freely inserted into and removed from the insertion recess, and above a headlamp provided at a front portion of the vehicle body and An upper connecting part that supports the wind screen by the insertion convex part inserted in the insertion concave part at the approximate center of the vehicle body, and the difference inserted in the insertion concave part on both the left and right sides of the headlamp. A connecting portion having a pair of lower connecting portions that support the windscreen by a protruding convex portion, and the vehicle body and the windscreen. A hook provided on one of them, a lock provided on any one of the vehicle body and the windscreen and movable between a hook position and a release position of the hook, and the lock from the release position to the hook position. An operating lever for moving and fixing the windscreen supported by the connecting portion.

  According to the present invention, a windscreen device for a motorcycle capable of holding the windscreen on the main body even in an unlocked state and preventing the dropout without impairing the ease of attaching and detaching the windscreen even in one-person work. Can provide.
