Description

[Detailed description of the invention] This invention is applied to handles for operating rotating parts such as opening/closing doors of cameras, radios, and other general equipment, and film rewinding shafts of cameras. The invention relates to the structure of the operating handle.

Generally, the above-mentioned operating handle is configured such that the grip portion thereof is kept in a collapsed position when not in use, and in an upright position when in use.

Conventionally, as a structure to restrict such arbitrary swinging of the gripping part, a plate-shaped click spring is applied to the gripping part, or a friction force is generated between the gripping part and the member supporting it. , a structure was adopted in which rocking was restricted by this frictional force.

That is, the former, as shown in Figure 1 a and b,
a semicircular gripping member 2 pivotally attached to the support member 1;
A leaf spring 4 is interposed between the support member and the surface of the body 3 of the camera, radio, etc., to which the support member is attached, and the leaf spring 4 is connected to the side surface 2a of the grip member 2 and the end surface 2a of the grip member 2.
By forming the grip member 2 in such a way that it can alternatively abut against the grip member 2, the grip member 2 is maintained in the illustrated collapsed position and upright position.

However, in such a configuration, a gap must be provided between the head of the support member 1 and the gripping member 2 and the surface of the body 3 in order to insert the leaf spring 4. There is a drawback that dust can enter the interior, and this gap is also
Since the support member 1 and the gripping member 2 have to be relatively large in order to allow elastic deformation, the head of the support member 1 and the gripping member 2 protrude greatly from the surface of the fuselage body, which has the drawback of significantly impairing the aesthetic appearance.

On the other hand, as shown in FIGS. 2a and 2b, the latter uses frictional force to restrict the swinging of the gripping member.
The pivot shaft 5 of the gripping member 2 and the support member 1 are fitted together somewhat tightly to generate a frictional force between them, and the pivot shaft 5 is divided into two parts and movable in the axial direction, as shown in FIGS. 3a and 3b. In addition to the two shafts 5a and 5b, the gripping member 2 that fixes the shafts 5a and 5b is formed of a spring member that contracts in the centripetal direction, and the inner peripheral surface of the gripping member is supported by the spring force. The gripping member 2 was formed so as to be held at any position between the lying and standing positions by the frictional force generated between the member 1 and the outer circumferential surface of the head.

However, such a configuration that utilizes frictional force has the disadvantage that it lacks durability because the sliding parts wear out over a long period of use, and in the configurations shown in FIGS. It is difficult to control the finishing accuracy of both members in order to fit them with the desired tightness, and in the case of the parts shown in FIGS. Both conventional examples are not easy to manufacture, as they must be formed to be slightly smaller than the outer circumferential diameter of the head of the support member 1, which makes dimensional control difficult, resulting in increased costs.

This invention was made in order to eliminate the drawbacks of the above-mentioned conventional examples, and its purpose is to bring the grip part and the supporting member for supporting it into close contact with the surface of the body of the camera, radio, etc. It is possible to prevent dust from entering the inside of the machine, improve the aesthetic appearance, and have excellent durability so that the grip can be held in any position even after long-term use, and is inexpensive. The object of the present invention is to provide an operating handle that can be manufactured.

Embodiments of this invention will be described below with reference to the accompanying drawings.

Figures 4a and 4b show an embodiment of this invention, where 10 is a body such as a camera or a radio, and 11 is a body attached to this body in a movable state to perform a predetermined operation such as rotation, or The support member 11 is formed of a shaft portion 11a and a disk-shaped support portion 12 which is located at the head portion and is in close contact with the surface of the aircraft body. 13 is the support member 1
This is a substantially donut-shaped recessed part formed on the lower surface of 2 with the shaft part 11a as the center, and an inclined surface 15 that slopes away from the shaft part 11a toward the bottom surface 14 is integrally formed on the outer annular wall surface part. is formed.
Reference numeral 16 denotes a pivot shaft rotatably supported by the support portion 12, and this pivot shaft 16 is approximately parallel to the surface of the fuselage body, and a portion of the pivot shaft 16 penetrates the recessed portion 13 and is exposed from the bottom surface 14 of the recessed portion. Supported. A semicircular grip portion 17 is fixed to both ends of the pivot shaft 16 by known means such as a tight fit. Note that both ends of the gripping portion 17 are formed into a semicircular shape with the pivot shaft 16 as the center, with rounded corners so that the gripping portion can rotate around the pivot shaft. 18 is a substantially ring-shaped spring inserted into the recessed portion 13;
8 is given a spreading habit so as to come into contact with the inclined surface 15. Incidentally, bent portions 19, 19 are provided at both ends of the spring 18 to serve as knobs for inserting the spring into the recessed portion during assembly.

In the above configuration, the expanding behavior of the spring 18 within the recessed portion acts as a pressing force against the pivot shaft 16 as indicated by the arrow due to the action of the inclined surface 15. Therefore, the gripping member 17 is reliably held in the upright position raised from the illustrated collapsed position and any desired position therebetween by the action of the pressing force applied to the pivot shaft 16.

As shown in the above embodiment, the concave portion is formed in the shaft portion 11a.
The shape of the spring is compared when the spring is formed into a substantially donut shape with the center at the center and has a tendency to spread so as to come into contact with the inclined surface 15 formed on the outer wall surface of the recessed part. Since the target can be made larger, assembly becomes easier, and since the force applied to the pivot shaft 16 can be increased, the gripping member 17 can be held securely.

5 and 6 both show other embodiments of this invention, and for the sake of simplifying the explanation below, the same reference numerals are given to the same members as in the first embodiment, and overlapping descriptions are given. The explanation will be omitted.

In FIGS. 5a and 5b, the inclined surface is formed on the small-diameter (inner) wall surface of the wall surface forming the donut-shaped recess, that is, on the circumferential side of the shaft portion 11a, and the slope is directed toward the bottom surface 14 of the recess. The above-mentioned shaft portion 11
It is set to form an inclined surface 25 in a direction approaching the axis of a. And on this inclined surface 25,
A substantially ring-shaped spring 28 which has a tendency to contract so as to reduce its diameter is brought into contact with the inclined surface 25.
is applied as a pressing force to the pivot 16 by the action of
As a result, the gripping member 17 can be held at any position as in the first embodiment.

As shown in this embodiment, if the inclined surface 25 for controlling the urging direction of the spring 28 is formed on the peripheral wall of the shaft portion 11a of the support member, when forming the inclined surface 25 by cutting, Since the degree of freedom in the tool delivery direction is maintained, manufacturing can be made extremely easy.

6a and 6b show another embodiment in which the shape of the pivot shaft 16 is changed from the first or second embodiment, in which a portion of the pivot shaft 16 exposed in the concave portion 13 is
A plurality of flat portions that can come into contact with the spring 18 are formed, for example, two flat portions 30 and 31 forming an angle of 90 degrees with each other.

As shown in this embodiment, by forming a plurality of flat portions on the portion of the pivot shaft 16 against which the spring 18 comes into contact, a click-stop-like feel can be provided when the gripping member 17 is operated. Furthermore, if a flat portion is formed at the portion where the pivot shaft 16 comes into contact with the spring when the grip portion 2 is in the collapsed position and in the upright position, the hand can receive the setting of the grip member in both these positions. Since the operation can be performed intuitively by touch, it can be extremely convenient when operating in a dark place.

In each of the above embodiments, only a substantially ring-shaped spring was described as a biasing member for pressing the pivot shaft 16, but the present invention is not limited to this spring. Any shape, such as a substantially V-shape or a substantially U-shape, can be used as long as it comes into contact with the slope formed in the recessed part.
In that case, it goes without saying that the cross-sectional shape of the inclined portion should be made in accordance with the shape of the spring.

Further, in each of the above embodiments, only the case where the recessed part 13 is provided on the lower surface of the support part 12 of the head of the support member, that is, the side where the support part 12 faces the surface of the body of the camera or the like, is shown. The portion 13 is not limited to this, and may be provided on the upper surface of the support portion 12. When configured in this way, the spring 18,
28 becomes extremely easy to attach and detach, so assembly and repair work can be speeded up. Further, the shape of the head is not limited to circular, but may be square or any other shape depending on the purpose.

As is clear from the above description, this invention has a support member rotatably bearing a shaft member fixed to a gripping member, and a recessed portion for exposing a part of the shaft member. The gripping member can be held at any position by pressing the shaft member exposed from the recess with a biasing member, and the biasing member itself comes into elastic contact with the wall surface of the recess. Since the shaft member is held within the support member and is configured to press the shaft member by the action of the inclined portion formed on the wall surface, the spring is lower than that of the conventional example shown in FIG. There is no need to support cameras, radios, etc. on the surface of the aircraft body, and they can be provided within the support member itself, so the support member and gripping member can be closely attached to the surface of the aircraft body, improving the aesthetic appearance and preventing dust from entering the aircraft body. Intrusion can be prevented.

In addition, in this invention, as a means for holding the gripping member at any position between the collapsed and upright positions, a configuration is adopted in which a pivot shaft fixed to the gripping member is pressed by a biasing member. And compared to the conventional example shown in Figure 3, which utilizes the frictional force generated between the gripping member and the supporting member that bears it, it is not affected by wear due to long-term use, so it is durable. Since the gripping member has excellent properties and is configured to be pressed by a biasing member, the gripping member can be held securely even if there is a slight play between the gripping member and the supporting member that supports it. The precision and dimensions of both members do not need to be controlled with such high precision, and therefore manufacturing costs can be reduced.
