Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a tele or wide adapter that is attached to and detached from the front surface of a light emitting unit of a flash device.

There are two types of adapters: close-contact type adapters that are used almost closely in front of the light emitting part of the flash device, and hood type adapters that are used with a hood and a predetermined distance from the light emitting part. 2. Description of the Related Art As an adapter mounting device, one is conventionally known in which a protrusion provided on an adapter-side mounting member is engaged with and disengaged from a concave groove provided on both side walls of a light emitting portion. Regarding the placement of the groove provided on the side wall of the light emitting part, it is preferable to arrange it closer to the front of the light emitting part in the case of a close-contact type because the shape of the mounting member on the adapter side can be made smaller, but when using a hood In contrast to the case of a close-contact type, it is preferable to provide the adapter closer to the rear of the light emitting part, since there is not necessarily sufficient gripping space in front of the light emitting part compared to an adapter that protrudes largely toward the front of the light emitting part. For this reason, even if grooves are provided in two places, one near the front and the other near the rear, on both side walls of the light emitting part, if the shape and dimensions are the same, when attaching the hood type adapter to the light emitting part, There is a risk of accidentally installing the product in the groove toward the front of the side walls when it should be installed in the groove toward the rear. The middle hood type adapter may fall. In addition, when changing the light distribution using a hood type adapter, design the installation position of the adapter based on the light emitting surface, but as mentioned above, if the adapter is installed in the wrong position, the correct light distribution may not be obtained. I had the inconvenience of not having one.

An object of the present invention is to provide an adapter mounting device that can eliminate the above-mentioned disadvantages.

To explain the embodiment, reference numeral 1 denotes the main body of the flash device, and a flash emitting unit 2 is attached horizontally to the top of the main body 1. On both side walls of the flash emitting unit 2, there are two pieces of glass having different shapes, dimensions, or structures.
The first and second adapter attachment parts 3 and 4 are provided. 5 is a close-fitting type adapter for telephoto or wide-angle photography that is attached to the front of the flash unit 2. The adapter 5 is attached to the center of both the left and right ends of the adapter 5.
The mounting members 6, 6 protrude parallel to each other in the same direction in the thickness direction, and protrusions 7, 7 are formed at their tips to engage with the first adapter mounting portions 3, 3, which are rectangular grooves provided near the front of the flash light emitting unit 2.

Reference numeral 8 denotes a hood-type tele or wide-angle adapter that is attached to the front of the flash unit 2, and the adapter 8 contracts toward the frame 9 that fits into the front part 2a of the flash unit 2. A hood part 10 is provided. Attachment members 11, 11 are made to protrude parallel to each other in the direction opposite to the hood part 10 from the center of both left and right ends of the frame part 9, and the frame part 9 is fitted into the front part 2a of the flashlight emitting part 2 at the tip thereof. When combined,
A rectangular first section is provided near the rear of the flash light emitting section 2.
Protrusions 12, 12 are formed to engage with second adapter attachment parts 4, 4, which are concave grooves having longer dimensions in the vertical direction than the adapter attachment parts 3, 3.

Since the present invention has the above-mentioned configuration, if the contact type adapter 5 is attached to the front of the flashlight unit 2, the protrusions 7, 7 of the mounting members 6, 6 will be attached to the first adapter near the front of the flash unit 2. It engages with the attachment parts 3, 3 to hold the contact type adapter 5 in its normal position. Similarly, if the frame part 9 of the hood type adapter 8 is attached to the front part 2a of the flashlight emitting part 2, the mounting member 11,
The protrusions 12, 12 of 11 engage with the second adapter attaching parts 4, 4 on the rear side of the flashlight emitting part 2, and hold the hood type adapter 8 in the normal position. Moreover, in installing this hood type adapter 8, since the vertical dimension of the protrusion 12 is larger than the vertical dimension of the first adapter attachment part 3, the protrusion 12 engages with the first adapter attachment part 3. This never happens, and the hood type adapter 8 is always engaged with the second adapter attachment part 4 to attach it to the normal position. This prevents the hood type adapter 8 from detaching from the flashlight unit 2 and falling during use, and even when changing the light distribution, it is possible to reliably prevent light distribution mistakes due to incorrect installation positions. .

FIG. 3 shows another embodiment in which the adapters 5 and 8 are attached to both side walls of the flashlight emitting unit 2.
While the first and second adapter attachment parts 3 and 4 in FIG. 1 are rectangular grooves with different vertical dimensions, the first and second adapter attachment parts 3a and 4
The shape of a is different from a rectangle and is circular, and the diameter of the second adapter attachment part 4a is larger than that of the first adapter attachment part 3a.

In this embodiment, the hood type adapter 8
The circular protrusions (not shown) provided on both mounting members 11, 11 have a diameter larger than that of the first adapter mounting portion 3a and do not engage with the first adapter mounting portion 3a. The adapter 8 can always be engaged in the correct position.

FIG. 4 shows yet another embodiment in which the adapters 5 and 8 are attached to both side walls of the flashlight emitting section 2, and the triangular dimensions of the first and second adapter attachment sections 3a and 4b are the same. This shows the case where the shape is different when the orientation is taken into account.

In this embodiment, the hood type adapter 8
The triangular protrusions (not shown) provided on both the mounting members 11, 11 are the first adapter mounting portions 3b.
The hood type adapter 8 can always be engaged in the correct position because the hood type adapter 8 is in a different direction and never engages.

In addition, in each of the above embodiments, the flashlight emitting unit 2
Although the case where the grooves of the first and second adapter mounting parts 3 and 4 provided on both side walls of the adapter have the same shape but different dimensions and orientations has been described, it is possible to A combination of different shapes may also be used.

Further, the first and second adapter attachment parts 3 and 4 may have other configurations instead of the concave grooves, for example, protruding pieces, and may be engaged with engagement grooves formed inside the attachment members 6 and 11 of the adapters 5 and 8. You can do it like this.

As is clear from the above explanation, according to the present invention, the adapter attachment parts provided on both side walls of the flashlight emitting part are provided in two places, one near the front and the other near the rear of the light emission part, and the mounting part for the contact type adapter is In order to prevent the hood type adapter from being attached, both adapters can be made to have different shapes, dimensions, or structures and can be used as dedicated adapter attachment parts for the contact type and hood type, respectively, so both adapters can always be installed in the correct attachment position. At the same time, it is possible to reliably eliminate the inconveniences such as falling of the adapter during use and failure to obtain correct light distribution caused by incorrectly attaching the hood type adapter to the attachment part for the contact type adapter.
