Description

[Detailed Description of the Invention] Technical Field This invention relates to a hanging cord connecting device for a camera that connects a hanging cord to a camera body.

Prior Art A conventional example of a camera suspension cord connecting device for connecting a suspension cord to a camera body is shown in FIGS. 1 and 2.

The hanging cord connecting device shown in FIG. It consists of a hanging ring fitting 5 which is interlinked and is fixed by being directly screwed onto the camera body using the threaded portion 3 of the hanging ring fitting connecting member 4.

However, in this hanging ring connecting device, the hanging ring fitting 5 has a structure in which the openings are overlapped in a spiral shape to close the hanging ring fitting 5, and the hanging ring fitting 5 is connected to the through hole 1 of the hanging ring fitting connecting member 4. This has to be done by so-called spiral threading, which has the drawback that the work is troublesome and leads to a decrease in the efficiency of the assembly process.

On the other hand, the suspension string connecting device shown in FIG.
A part of the shaft area 8a of the pivot 8 of the hinge 7 which is pivotally attached to the camera body is used for connecting the suspension string, and the hook fitting 10 attached to the base end of the suspension string 9 is used to connect the suspension of the pivot 8. By engaging the string connecting shaft area 8a, the hanging string 9 can be connected to the camera body via the hinge 7 for attaching the back cover.

In the case of this hanging cord connecting device, when the camera is suspended by the hanging cord 9, the entire load of the camera is concentrated on the hanging cord connecting shaft region 8a where the hook fitting 10 is engaged, so that the hinge The pivot 8 of 7 is susceptible to bending deformation with use, which may impede the opening/closing operation of the back cover 6. This causes the inconvenience that number 7 becomes larger. In addition, relief grooves 6a and 7a for the hook metal fitting 10 are formed in each edge of the back cover 6 and the hinge 7 near the hanging string connecting shaft area 8a, so that the hook metal fitting 10
Since the locking is performed smoothly, light rays are likely to leak from the escape groove 6a, and the hook fitting 10 that is locked becomes an obstacle, making it impossible to fully open the back cover 6 to nearly 180 degrees. It also has problems such as making attachment and detachment operations difficult.

Purpose The purpose of this invention is to eliminate the above-mentioned drawbacks of conventional camera suspension string connecting devices, and to provide easy assembly and sufficient strength.

Embodiment An embodiment of the camera sling connecting device of this invention is shown in FIGS. 3 and 4. As shown in an exploded perspective view in FIG. 3, this camera hanging cord connecting device consists of a hanging ring fitting 11, which has a rectangular shape and to which the hanging cord is directly connected, and a camera body 12, which has a mouth-like shape and is connected directly to the hanging ring fitting 11. A recess is formed on the surface of one side of the hanging ring fitting 11, into which the hanging ring fitting 11 is loosely fitted, and the hanging ring fitting 11 is overlapped with the opening of the rear longitudinal groove 13a of the hanging ring fitting receiving groove 13. A back cover mounting hinge 15 in which a cover piece 14a connected to one side of the main body 12 in a linked manner is formed protruding from one side edge of the mounting plate 14, and a cover piece of the back cover mounting hinge 15. 14a, and a decorative board 16 covering the surface 14a.

The hanging ring fitting receiving groove 13 has a protruding frame 17 along its outer periphery excluding the rear vertical groove 13a, and has concave portions 18, 18 into which the decorative board 16 is fitted to the outer periphery of the rear vertical groove 13a. is formed.

The back cover mounting hinge 15 has a sleeve-shaped bearing part 14b that pivotally supports the back cover pivot on the side edge opposite to the other side edge of the mounting plate part 14, that is, the one side edge from which the cover piece part 14a is formed protrudingly. 14b, and the mounting plate part 14 is tightened and fixed to the surface of one side of the camera body 12 with screws 19 through the screw insertion holes 14c provided separately in the mounting plate part 14, and at the same time, the hanging ring metal receiving groove is tightened and fixed. As shown in the horizontal cross-sectional view in FIG.
The opening of the rear vertical groove portion 13a is closed with a lid piece portion 14a. Notches 14d, 14d are formed in a part of the upper and lower sides sandwiching the lid piece 14a on one side edge of the mounting plate 14 from which the lid piece 14a is formed to protrude. The decorative board fitting recesses 18, 18 are prevented from being blocked by the mounting plate part 14.

The decorative plate 16 is the cover piece part 1 of the hinge 15 for mounting the back cover.
4a, and a protruding frame part 16b that continues to the protruding frame 17 of the hanging ring metal receiving groove 13 and frames the outer periphery of the rear vertical groove part 13a. Mounting bases 16c, 16c are formed on the edges to fit into the decorative plate fitting recesses 18, 18, and the cover piece 14a of the back cover mounting hinge 15 is attached to the camera body 12 when assembled into the camera body 12. From the rear side, the rear vertical groove part 1 of the hanging ring metal receiving groove 13
A concave groove 1 for fitting the lid piece is formed on the back surface of the cover 16a so that the opening 3a can be inserted into a position where the lid can be closed.
6d. Fitting pins 16e, 16e', 16e' are provided protruding from the back surfaces of the cover part 16a and the mounting bases 16c, 16c, respectively, so that the lid piece part 14
The fitting pins 16e, 16 are inserted into the positioning holes 21, 21', 21' provided separately in a part of the protrusion 20 to be bridged and in the corners of the decorative board fitting recesses 18, 18.
e' and 16e' are fitted to secure the camera body 12. In FIG. 4, 22 is a patch of leather.

As mentioned above, in this embodiment, the decorative board 16
Although the back cover mounting hinge 15 can be fixed after being fixed to the camera body 12, the assembly order may be reversed.

The hanging ring fitting 11 is not limited to a closed ring structure with no seams in the middle as shown in FIG. good.

Effects The camera suspension string connection device of this invention has a suspension ring metal receiving groove 13 formed in a part of the camera body 12.
The hanging ring fitting 11 is inserted into the rear side vertical groove part 13a of the hanging ring fitting receiving groove 13 with the lid piece 14a formed at one end of the mounting plate part 14 of the back cover mounting hinge 15 fixed to the camera body 12. Since the opening is closed and one side 11a of the hanging ring fitting 11 is chain-connected to the camera body 12 side, it is possible to connect the hanging ring fitting 11 to the camera body 12 side without the need for spiral threading work. Interchangeable connections can be made, assembly is easy, and the suspension ring fitting 11 is not limited to a spirally wound structure, allowing a wider range of member structures to be selected. The load will be applied to the cover piece 14a formed at one end of the mounting plate part 14 of the back cover mounting hinge 15, ensuring sufficient strength, and the load of the camera will not affect the pivot of the back cover. Inconveniences such as bending and deformation that impair the opening and closing operations of the back cover can also be prevented.

Moreover, since this camera hanging strap connecting device is located a little apart from the pivot point of the back cover, the hook 10 can be used to fully open the back cover, as in the conventional example shown in FIG. There is no need to form an escape groove 6a for the hook fitting 10 on the back cover side, and there is no fear of light leakage due to the escape groove 6a.
