JPH08137006A - Installing lock mechanism for accessory shoe adapter - Google Patents

Abstract

PURPOSE: To provide a falling-off preventive lock mechanism by which a user is not struck by unexpected trouble due to unexpected external force even with the intention of being reliably installed when an accessory part or the like is installed on a camera by inserting a locking plate into an eyecup installing groove from both sides of a plate part. CONSTITUTION: When a connecting shoe 8 of an accessory shoe adapter is inserted into a hot shoe 7 of a camera, a notch part formed on a plate part 1 is fixed to the camera side in the shape of striding over a camera eyepiece part frame 2. In order to perfectly lock this condition, when a locking plate is inserted into an eyecup installing groove 3 of the camera, the accessory shoe adapter is perfectly fixed to the camera. In this way, when the locking plate is inserted into the eyecup installing groove 3 from a side surface, the accessory shoe adapter is fixed without being carelessly dislocated to the rear of the camera.

2. Description of the Related Art September 12, 1994. Patent publication decision in 1990: Patent application: No. 73134: A mechanism designed to more securely attach the reinforced accessory shoe adapter. Fig. 3 shows a partially enlarged plate portion of (1). is there. The perspective view of FIG. 1 is the one determined by the public notice, and the lock mechanism according to claim 1 is incorporated in the plate portion (1) of the accessory shoe adapter.

[0003]

[Problems to be Solved by the Invention] When an accessory part or the like is attached to a camera, unexpected trouble may occur due to unexpected external force even if it is intended to be surely attached. It is a locking mechanism to prevent falling, which was designed to ensure safety in order to prevent such problems.

[0004]

[Means for Solving the Problem] The locking plate (4) is inserted into the eyecup mounting groove (3) of FIG. 2 from both sides of the plate portion (1) straddling the eyepiece frame of the camera to try to lock it. thing.

[0005]

When the connection shoe (8) of the accessory shoe adapter is inserted into the hot shoe (7) of the camera in the side mounting view of FIG. 4, the cutout portion made in the plate portion (1) causes the camera eyepiece frame (2). ) Is fixed to the camera side. If the locking plate (4) is inserted into the eyecup mounting groove (3) of the camera to completely lock this state, the result is that the accessory shoe adapter is completely fixed to the camera.

[0006]

Embodiment 1 Insert the accessory shoe adapter shown in FIG. 4 into the camera with the insertion knobs (5) shown in FIG. 3 pulled out to both sides. Fix the adapter sufficiently in this state. In addition to this, when the insertion knobs of (5) are pushed in so that the camera eyepieces on both sides are pinched after mounting, the locking plate (4) attached to the tip of the knobs is for attaching the eyecup in FIG. It is inserted into the groove.

[0007]

[Effects of the Invention] By inserting the locking plate (4) into the eyecup mounting groove from the side surface, the accessory shoe adapter is fixed without being accidentally displaced toward the rear of the camera.
