Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film winding lever for a camera, and more particularly to a film winding lever provided on the top surface of the camera for winding up the film loaded in the camera.

As is well known, a film winding lever is provided on the top surface of the camera, and is capable of winding up the film loaded in the camera one frame at a time. A conventional film winding lever of this type has been constructed as shown in FIG. 1, for example. That is, the conventional film winding lever 1 includes a winding arm 3 whose base is integrally attached to a winding mechanism connecting shaft 2 connected to a film winding mechanism (not shown) of a camera, and a base of this winding arm 3. an exterior sheathing member 4 that covers the sheathing member 4; a tightening screw member 5 that fixes the hoisting arm 3 to the hoisting mechanism connecting shaft 2 through the through hole 4a of the sheathing member 4; The operating finger rest 7 is fixed to the free end of the upper arm 3.

The winding upper arm 3 is formed of a plate-like member with a circular base and a free end that becomes narrower toward the tip and gently curves toward the camera body. An oval hole 3a for attaching the arm 3 to the winding mechanism connecting shaft 2 is bored. This oval hole 3a fits into a mounting seat 2a formed in an oval shape on the head of the connecting shaft 2, and serves to stop the hoisting arm 3 from rotating with respect to the connecting shaft 2.

The exterior covering member 4 has a disc shape with a through hole 4a bored in the center, and has a hem portion on the peripheral edge of the lower surface for concealing the peripheral side of the base of the upper arm 3. 4b is formed to hang down. This covering member 4 is fitted to the base of the upper arm 3, and the notch of the hem 4b abuts against the notch 3b formed near the base of the upper arm 3.
It is fixed and prevented from rotating relative to the base of the winding arm 3.

The tightening screw member 5 has a screw shaft 5 at the center of the lower surface.
It is formed of a disc-shaped member provided with a,
On its upper surface, there is provided a clamping hole 5b and a ring-shaped projecting wall 5c surrounding the tightening hole 5b.
is formed. This tightening screw member 5 is attached to the screw shaft 5a through the through hole 4a of the covering member 4 and the oval hole 3a of the hoisting arm 3, and the screw shaft 5a is attached to a mounting screw bored into the head of the hoisting mechanism connecting shaft 2. It is designed to be screwed into the hole 2b, and by this screwing, the winding arm 3 and the covering member 4 are prevented from coming off and attached to the connecting shaft 2 as one body. The exterior disc 6 is fixed to the circular area surrounded by the projecting wall 5c on the top surface of the tightening screw member 5 with adhesive or the like so that the cannibal hole 5b is not exposed to the outside. It is becoming more and more like this.

In FIG. 1, reference numeral 21 indicates a decorative top plate of the camera, 22 indicates a film sensitivity setting knob, and 23 indicates a shutter release button.

The conventional film winding lever 1 is constructed in this way, but in this winding lever 1,
It has the following drawbacks.

(1) The clamping hole 5b, which is essential in the assembly process of the winding lever 1 but has no bearing on the camera user, is exposed on the external surface, so the hole 5b should not be An exterior disc 6 is required for good concealment, which increases the number of parts and increases manufacturing costs.

(2) The winding lever 1 is a part that is assembled with great force during the camera manufacturing process, and therefore the winding arm 3, the tightening screw member 5, the finger rest member 7, etc. are easily damaged. Once these parts are damaged, it becomes necessary to replace them because they are external parts, resulting in a decrease in product yield.

The purpose of the present invention is to solve the above-mentioned conventional drawbacks by attaching an exterior sheathing member that covers the joint between the two, after attaching the hoisting arm to the hoisting mechanism connection shaft, and attaching a finger rest member to the hoisting arm. To provide a film winding lever for a camera which is fixed to the winding arm at the same time.

According to the present invention, the exterior covering member, which cannot be attached unless the back side of the winding arm is seen because the camera body gets in the way, can be fixed to the winding arm at the same time by attaching the finger rest member to the winding arm. Therefore, tightening holes and grooves that are of no concern to the user of the camera are not exposed on the external surface.

Further, since there is no need for an exterior member to hide the tightening holes and grooves, the appearance can be made beautiful by reducing the number of parts, and manufacturing costs can be reduced.

In addition, external appearance members such as exterior covering members and finger rest members can be assembled in the final assembly process after the hoisting arm is firmly tightened and attached to the hoisting mechanism connecting shaft with screws, so they may be damaged. It is possible to significantly improve product yield.

Furthermore, since the winding upper arm is covered by two members, the cover member and the fingering member, and is not exposed at all, the color scheme of the winding lever can be freely selected. For example, if the camera has a normal metallic body, the covering member is silver and the finger rest is black, and if the camera has a black body, both the covering member and the finger rest are black.
The color scheme of the winding lever can be made in harmony with the color of the camera body. In particular, when the camera has a black body, if the covering member and the finger rest are made of the same material with the same color, the entire winding lever can be made in the same color and with the same gloss, which further improves the appearance. It can be made beautiful.

Hereinafter, the present invention will be explained based on an illustrated embodiment.
