Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a hand strap attached to a camera.

``Prior Art'' A hand strap is often attached to a camera in order to ensure that the camera is held securely and stably when taking pictures, and to prevent the camera from falling off when carried with one hand. Such hand straps have been widely known and come in various shapes and structures, one example of which is shown in FIG.

The illustrated hand strap includes a pad 1 and belt-shaped bands 2a, 2 extending from both sides of the pad 1.
The band 2a is folded back through the hanging bracket 4 located at the upper side of the camera 3 and attached by gluing a hook-and-loop fastener provided on this band, and the band 2b is attached to the side of the camera 3. It is attached by folding it back through the hanging metal fitting located at the bottom of the holder and securing the folded part with a hook. In the hand strap as described above, the pad 1 comes into pressure contact with the back of the hand that grips the camera 3, so the hand is pressed against the side of the camera and the camera is maintained in a gripping state.

``Problem to be solved by the invention'' Since the hand strap mentioned above is attached with hook-and-loop fasteners or hooks, there is a risk that the attachment part may come off for some reason and cause the camera to fall. Not necessarily desirable. Furthermore, since the pad 1 presses not only on the back of the hand but also on the first joint of each finger, the movement of each finger is suppressed by the pressure of the pad 1, making it difficult to operate the camera with the fingers.

Furthermore, when using the above-mentioned hand strap, you have to directly hold the side of the camera with your hand, which may not provide a sufficient grip for cameras with a small gripping area, making it difficult to hold the camera with one hand. The grip becomes unstable.

In view of the above-mentioned problems, the present invention aims to develop a hand strap that securely holds the camera, improves operability, and is securely attached.

"Means for Solving the Problems" In order to achieve the above-mentioned object, the hand strap of the present invention has a first hand strap which extends the strap and which can be freely latched to a strap passage provided on the side of the camera. A mounting body is provided with a second hook member projecting thereon, and the first hook member is moved to the mounting body so as to move between a first position in which the strap is engaged with the strap passage portion and a second position in which the engagement is released. an operating member that is freely provided, the second hook member is fixed to the mounting body, and is coupled to and drives the first hook member;
A locking mechanism for locking the first hook member that has moved to the first position and preventing the movement thereof is operable on the mounting body.

"Operation" When attaching the hand strap, move the first hook member to the second position, and while inserting the second hook member into the strap passage, move the attachment body closer to the side of the camera. In this state, move the first hook member to the second position, and insert the first hook member into the other strap passage part.
Insert the hook member.

When both the first and second hook members lock the strap passing portion, the lock mechanism locks the first hook member to prevent movement.

When removing the hand strap, after releasing the lock mechanism, the first hook member is moved from the first position to the second position and removed from the strap passage. When the attachment body is moved slightly in one direction in this state, the second hook member comes out of the strap passage portion and the hand strap is removed.

"Example" Next, an example of the present invention will be described with reference to the drawings.
