Abstract

The invention relates to photographic equipment and can be used mainly in small-format cameras with a rigidly built-in lens. The purpose of the invention is to improve the ease of handling the camera. The camera includes a housing 1 with an integrated lens 2. a protective lens cover 4, a spring-loaded slider 6 and a slider 9 for locking the release button. When moving the protective cover 4 of the lens from the Closed to the Open position, it, with its protrusion 46, interacts with the flexure 6a of the slide b at the end of the stroke and, overcoming the resistance of the spring 7. displaces the spring-loaded slide b by an amount sufficient for the deflection 66 of the spring-loaded slide 6 to exit from interacting with the protrusion 9a of the slide 9 blocking the shutter button, thereby unlocking it. When the protective cover 4 of the lens is moved from the Open to the Closed position, its protrusion 4a releases the bend of the spring-loaded slider 6 and is shifted to the left by the action of the spring 7. In this case, the bend 66 of the spring-loaded slider 6 will become EYT in the way of the protrusion 9a of the slider blocking the release button 9, blocking it. 3 il. w N

The invention relates to photographic equipment, and in particular to the design of a camera, and can be used in small-format cameras with a protective cover and a hard-wired lens.

Protective covers of the lens are known - sliding, swiveling, folding in the form of a curtain with a hole.

A common disadvantage of such covers is the cumbersome design. To open and close such a lid, a special mechanism is needed to transmit movement from the release button. In such constructions, the trigger button is not blocked.

The protective cover of the camera lens is also known, which is mounted on the body of the camera with the possibility of longitudinal movement and is made of two parts.

The disadvantage of this cover is the ability to expose when closed. volume of the lens by accidentally pressing the shutter button.

The purpose of the invention is to improve the ease of handling the camera.

Figure 1 shows the design of the protective cover of the camera lens in the closed position; figure 2 - the same, in the Open position; Fig. 3 shows the layout of the protective cover on the camera.

The design of the protective cover is the case of the protective cover 1 installed on the front side of the camera body with lens 2. In the case of the protective cover 1, a rectangular opening is made, and on the inner side of the case there are guideways 3a and 16, corresponding to the position of the protective cover Closed and Open.

The guides 3 in the opening of the housing 1 are fitted with a cover L with a finger Aa and a protrusion 46 on the elastic rib, which is a groove web, and elasticity is achieved due to the elasticity of the material.

On the guide posts 5, provided on the front wall of the camera from the inside, there is a slider 6 with ibb bend arms 6a, spring-loaded 7. On the guide posts 8, also provided on the inside side of the front wall of the case, a slider blocking the release button 9 sec. the protrusion 9a, spring-loaded spring 10. On the inner side of the housing 1, the protective cover 4 is fixed by a plate 11 in which a hole is made for the lens / 2 rigidly mounted in the camera body and the cut for the finger 4a protective lens cover.

The protective cover works as follows.

In the closed position, the lid 4 by the protrusion 46 is fixed in the groove 1a. The slider 6 with the spring 7 is set to its original position. When this bend 66 locks the slider 9 blocking the shutter release button for the ledge 9a. In this position, the possibility of pressing the shutter button is excluded. When the cover is moved to the Open position, the protrusion 46 is squeezed out of the groove 1a due to the spring properties of the edge of the cover and the protrusion 46 is fixed in the groove 16 Open. In this case, the finger 4a shifts the PN chun 6 by bending 6a to the extreme position and displays

from engagement bend 66 with the protrusion 9a. Lock off The trigger button, together with the trigger 9, is able to operate.

The trigger lock mechanism prevents the shutter from being activated when the lens cover is closed.
