Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grip/lens protection device for a portable color camera in which the grip of the portable color camera is also used to protect the camera's image pickup element or lens.

Conventionally, the grip of a portable color camera only had the function of the grip alone, and had the disadvantage of being large in volume when carried while attached to the camera body. In addition, conventionally a cap was used to protect the camera lens, or to protect the image pickup tube or image sensor located behind the lens mounting opening inside the camera body from light and dust, but it is now possible to remove the cap alone. For example, if you drop it and lose it, or if you remove it, it is a hassle to store it.

Furthermore, there have been conventional portable cameras, such as Japanese Patent Publication No. 7779/1983, in which the lens surface of the portable camera is covered when the grip of the portable camera is folded. However, since the grip of this camera is attached to the front of the portable camera body, that is, on the same surface as the lens surface, the grip lacks stability and makes it difficult to hold the portable camera.

In addition, in the case of conventional grips, if the grip is attached to the center of gravity of the camera body, that is, in the center of the bottom of the camera body, in order to stably hold the grip, the grip can be made L-shaped.
The vertical piece of the mold must cover the lens or the opening between the lens and the camera body, but in this case it is difficult to completely cover the lens or the opening with the L-shaped vertical piece without any gaps. Various problems have been considered, such as:

The present invention solves the above-mentioned drawbacks by attaching the grip to a surface other than the lens mounting surface of the camera body, making the grip foldable or telescopic, and allowing it to be attached to the camera body and carried. When you hold the grip, the camera body is stable and easy to hold, and the volume is small, making it convenient to carry.The grip can also be used to protect the camera lens, or to open the lens mounting opening inside the camera body. To provide a grip and lens protection device for a portable television camera that protects an image pickup tube or an image pickup element on the back side from light, dust, etc.

An embodiment based on the present invention will be described with reference to the accompanying drawings. Fig. 1 is a plan view of a portable television camera showing one embodiment of the present invention, Fig. 2 is an exploded perspective view of the grip section showing the main parts of the invention, and Fig. 3 is an example of the use of the grip section of the present invention. FIG. In FIG. 1, reference numeral 1 denotes a camera body, to which a lens 12 is attached. 2 is a roughly elliptical grip made of, for example, resin and is thick enough to be easily held in the hand. Grip 2 is protector 2
a, a grip body 2b, and a fixing piece 2c.The grip body 2b is formed by fitting the groove 20 provided in the grip body 2b with the protrusion 19 of the fixing piece 2c, so that the grip body 2b is connected to the hole 11 of the grip body 2b and the fixing piece 2c. The grip body 2b and the fixing piece 2c are fixed by inserting a screw into the hole 22 of the protrusion 19 of the grip body 2c. Next, a description will be given based on FIG. The protector 2a is a substantially rectangular flat plate that protects the opening of the connecting portion of the image pickup tube or image sensor (FIG. 3A) when the lens 12 or the lens is removed, and has a hinge portion D on one end thereof.
The insertion part 6 for forming the lens protrudes and has a protective part 13 at the other end for protecting the lens 12 or the opening (FIG. 3A), and is made to have a suitable length. The protection part 13 is made by adhering a vibration-proofing material such as sponge, rubber, or cloth to a suitable position of the protection body 2a so as to be able to absorb the external force applied to the lens 12 or the opening A, and to sufficiently prevent the intrusion of dust and the like. It is made to a similar size. Grip body 2b
It has an almost cylindrical shape with a thickness that is easy to hold, and the protective body 2
It has a shaft part 5 on one end side so as to form a hinge part D with the insertion part 6 of a, and has an insertion part 4 protruding from the other end side to be inserted into the groove of another hinge part E, and has a suitable length. It is created in the same way. Further, the side surface of the grip main body 2b is provided with, for example, a groove 10 for preventing slipping.
A screw 21 screws the holes 11 and 22 together in the middle of the grip body. Insertion part 6 of protector 2a
and the shaft part 5 of the grip body are fitted and connected,
A hinge part D having appropriate hardness is formed,
A recess 14 is provided in the center of the grip body so that the protector 2a can be folded down and neatly stored in the grip body 2b. The fixing piece 2c is a substantially square-shaped flat plate with steps, and is attached to the insertion portion 4 of the grip body 2b.
It has a shaft part 3 on one end side so as to constitute a hinge part E, and has a screw hole 15 on the other end side, and the fixing piece 2c is attached to the screw hole 16 of the camera body 1 with a screw 18. The insertion portion 4 of the grip main body 2b and the shaft portion 3 of the fixed piece 2c are fitted and connected to form a hinge portion E having appropriate hardness. Since each hinge part is fitted and connected, the protector 2a and the grip body 2b are connected to the fixing piece 2c and attached to the camera body 1.

In the above configuration, when using the grip 2 as a grip function, the screw 21 is sufficiently tightened and the protector 2a is attached to the recessed part 1 at the hinge part D.
4, for example, in a clockwise direction, and store the protector 2a in the recess 14 of the grip body 2b. Furthermore, at the hinge part E, the grip body 2
When b is folded downward, it becomes a grip with a grip function in a vertical position. Next, when using the grip 2 to protect the camera lens, image pickup tube, image sensor, etc., loosen the screw 21 and move the grip body 2, for example, in the direction of the arrow in FIG. , E, extend the protector 2a and the grip main body 2b in a straight line, and then extend the hinge part D.
When the protector 2a is lowered vertically, the hinge part D has appropriate hardness, so the protector 2a is lowered vertically.
is held at that position, and the grip main body 2b and the protector 2a have a length from the mounting position of the fixed piece 2c to the lens 12 or the opening A, and a length from the hinge part D to the position of the lens 12 or the opening A, respectively. Since the height is suitably made, the lens 12 or the opening A can be protected by the protective piece 13. Furthermore, as shown in Fig. 3, when the lens is removed, the protection of the opening A is shortened by the length of the lens mentioned above, so if you change the mounting position of the screw 18 for attaching the grip body 2 accordingly, the lens Even when the camera body 12 is removed, the opening of the camera body 1 can be covered to protect the built-in image pickup tube and the like. Furthermore, if a recess is provided on the bottom surface of the camera body 1 so that the protector 2a, grip body 2b, and fixing piece 2c do not protrude from the bottom surface of the camera body 1, the appearance becomes smarter.

As explained above, the present invention has the excellent effect that the grip is foldable and has a small volume, making it convenient to carry, and that the grip can also protect the camera lens, image pickup tube, or image pickup element.

In addition, the present invention makes the protective body foldable or telescopic in the grip, so even if the grip is attached to the center of the bottom of a portable camera body, when the grip is folded, the protective body can be pulled out from the grip and removed from the lens surface and the housing. The opening where the body and lens are combined can be covered with a protector.
And since the grip cannot be attached to the center of the bottom of the portable camera body, holding the portable camera with the grip provides a sense of stability, compared to the conventional case where the grip is located at the front edge of the portable camera. It is easy to carry a portable camera. In addition, the protector can be folded or expanded into the grip, so the protector does not get in the way when holding the grip. The camera body can be stored compactly. Further, the grip may be attached to any surface other than the lens surface, and the above-mentioned effects can be obtained in this case as well.
