Description

Device for influencing light during the taking of photographs}

The present invention relates to a light-influence device for photographing that can be assembled quickly and can be easily operated.

When taking a picture, it is important to use light to illuminate the object or person being photographed. Of course, this importance of light also applies to film recording. When the lighting is well lit, even the most detailed details appear in the image. In particular, when taking a picture outdoors, there is a problem that the natural light is unevenly distributed. Thus, if the cloud obscures the sun or there are natural obstacles such as trees or hills, it may adversely affect natural light.

It is well known to reflect natural or artificial light using a reflector to illuminate the person being photographed. A reflector is used to disperse light under the aid of a diffuser or under the aid of a filter. The spectral components are taken into account to optimize the light.

To optimize light when taking pictures, use a support frame with an extension lid. The material of the expansion cover can be selected depending on the function (light reflection, light transmission or light filtration). Conventional expansion covers are made of a flexible material and are installed at the edge of a loop sewn in a circle. In the loop, a portion of the support frame is arranged to completely separate the expansion lid. Conventional support frames are made of aluminum tubes. These round aluminum tubes fit together and can be connected to one or more transverse tubes to improve dimensional stability. The transverse tube has a circumference of the same size as the circular aluminum tubes, which are connected to the circular aluminum tubes using a connecting member such as T-shaped brackets, and the T-shaped brackets are screwed together.

In this regard, for example, when taking a picture outdoors, there is a problem of disassembling and sending the support frame to each outdoor location and then reassembling it there. This assembly method is time consuming considering that the transverse tube must be attached to a round aluminum tube. In particular, a number of fastening members, such as screws, should be used, and these fastening members generally have to be fastened continuously in several places.

The object of the present invention is to provide a light-influence device for photographing that can overcome the problems occurring in the prior art, and in particular, can be quickly assembled and easily operated.

The present invention relates to a light affecting device during photographing (eg, image photographing or film recording) with a support frame and an extension lid. The support frame includes a first gripping rod attached to the first end of the extension cover and a second gripping rod attached to the second end of the extension cover relative to the first end. The support frame may further comprise at least one spreading rod, wherein the spreading rod has a distal receiving means having a concave receiving surface for accommodating an outer surface of one gripping rod, the at least one spreading rod being expanded The first gripping rods and the second gripping rods are formed to have a length in a state in which the cover is opened.

The spreading rod having the distal end receiving means is formed to accommodate the outer side surfaces of the first and second gripping rods in a state where the expansion cover is opened. In the case where the gripping rods are formed in a circular shape (tubular shape), the concave receiving surface is preferably formed in a semicircular shape (and also curved toward the center of the spreading rod) in the distal receiving means. Accordingly, the device of the present invention can be easily disassembled and transported, and can be quickly assembled during outdoor shooting. This structure eliminates the need for additional fastening means such as screws. For this purpose, after the expansion cover is unfolded, the spreading rod is inserted between the first and second holding rods (which are respectively fixed against the elasticity of the spreading rod itself or the elasticity of the expanding cover). The width B-B of the extension cover (from the inner edge of one gripping rod to the inner edge of the other gripping rod) will be as close as possible to the distance between the receiving surfaces of the at least one spreading rod. Preferably, the width of the extension cover may be selected according to the distance that the extension cover can be extended against the elasticity of the spreading rod.

According to a preferred embodiment, the extension cover is formed to be elastically at least partially within the width B-B between the first and second gripping rods. It is preferable that the width B-B of the expansion cover is formed to be shorter than the distance between the receiving surfaces of the at least one spreading rod in the state where the expansion cover is not expanded. Accordingly, the expansion cover can be unfolded on the spreading rod against the elasticity of the expansion cover itself.

Preferably, in the width B-B between the first and second gripping rods, the extension lid comprises a first elastic outer portion, a central portion adjacent thereto and a second elastic outer portion adjacent thereto. The elastic outer parts are used open to the central part made of elastic or inelastic material. Preferably, the elastic outer portions are preferably made of an elastic fabric material having a width of about 10 cm. The elastic outer portions have distal ends for securing the extension cover to each of the gripping rods.

According to a preferred embodiment, the central portion has a hole. This hole has a predetermined position and size (5 × 10 cm), allowing the user to look through the device of the present invention by hand.

Particularly preferably, the expansion cover includes a lockable device, respectively, between the first elastic outer portion and the central portion as well as between the second elastic outer portion and the central portion. That is, a zipper extending along the entire length (A-A) of the expansion cover may be provided to separate the elastic outer portion and the central portion. Accordingly, the central portion can be easily exchanged according to the desired purpose and material.

In addition, the central portion may include at least one rigid element. Preferably, each rigid element may consist of a piece of plastic extending along the entire length A-A of the central portion. The first plastic piece is provided in the center portion adjacent to the release lock between the first elastic outer portion and the center portion, and the second plastic piece is provided in the center portion adjacent to the release lock mechanism between the second elastic outer portion and the center portion. The rigid element is simply connected by a zipper, so that the center part can be installed very easily.

In addition, the spread bar may include a tube made of a carbon fiber material. This tube preferably consists of a tube of diameter 2 cm to 10 cm, in particular 4 cm to 8 cm, with a hollow cross section.

According to a preferred embodiment, the tube made of carbon fiber material comprises a first tubular portion and a second tubular portion. The first pipe part includes an inner pipe (which is firmly connected to the first pipe part and protrudes from the first pipe part), and the circumference of the inner pipe is formed to fit snugly to the second pipe part, whereby the first pipe part is formed. It is connected to the second pipe part. Accordingly, the spreading rod can be disassembled for transportation. The tubular portions may have a joint surface that is obliquely cut so as not to bend in an assembled state.

Particularly preferably, the support frame may include a first spreading rod and a second spreading rod. Accordingly, the support frame can be stably accommodated in a case larger in size. In addition, these spreading rods can be easily carried with both hands.

The device of the present invention can be easily disassembled and transported, can be quickly assembled during outdoor shooting, and can be easily manipulated, so that the photographing can be performed under an optimal light condition when taking a picture.

Hereinafter, with reference to the embodiment shown in the accompanying drawings will be described in detail the present invention.

1 shows a light-influence device 1 for photographing the invention with a support frame and an extension cover 4. The support frame may include a first gripping rod 21 attached to a first end of the extension cover 4, and a second gripping rod attached to a second end of the extension cover 4. 22).

The expansion cover 4 is designed to be partially elastic while being located within the width BB between the first and second gripping rods 21 and 22 (each inner edge), the inelastic central portion ( 43 is adjacent to the first elastic outer portion 41 and the second elastic outer portion 42. In this embodiment these elastic outer portions 41 and 42 have a width of approximately 10 cm and are distinguished from the distal ends formed by the edge marks of the expansion lid 4. A zipper 44 is provided along the line A-A between the first elastic outer portion 41 and the center portion 43 as well as between the second elastic outer portion 42 and the center portion 43. Accordingly, the central portion 43 can be exchanged according to the function of a reflector, a diffuser, an optical filter, or the like that enables the apparatus of the present invention to be used for various purposes.

The device 1 of the present invention is provided with first and second spreading rods 3, both ends of which are provided with receiving means each having a semicircular receiving surface (see FIG. 3), which includes an expansion cover. In the unfolded state (4) is accommodated the outer surface of the first gripping rod 21 and the second gripping rod (22). Therefore, the device 1 of the present invention can be easily disassembled and transported and can be quickly assembled during outdoor shooting. For this purpose, when the expansion cover 4 is unfolded, the two unfolding rods 3 are continuously fixed between the first holding rod 21 and the second holding rod 22. When the extension cover 4 elastically moves within the width BB between the first and second gripping rods 21 and 22, the spreading rods 3 are opposed to the elasticity of the expansion cover 4. Fixation can be made.

In the central portion 43, rigid plastic pieces 45 are provided along the entire length A-A in a state adjacent to the zipper 44, respectively. In addition, a through hole 46 is provided in the center of the expansion lid 4.

Figure 2 shows the back of the device of the present invention shown in Figure 1. The device 1 of the present invention includes a first spreading rod 31 and a second spreading rod 32 having a tube (center) made of a carbon fiber material. The tube is composed of a first tubular portion 311 and a second tubular portion 312.

The first pipe part 311 includes an inner pipe (not shown), and the circumference of the inner pipe is formed to fit snugly with the hollow second pipe part 312. Therefore, the first tubular portion 311 can be connected to the second tubular portion 312 and can be disassembled and transported. This is advantageous if the device 1 of the present invention is manufactured in particularly large dimensions. Opposite end portions of the first tubular portion 311 and the second tubular portion 312 are obliquely cut. Therefore, it is possible to prevent the connecting portion between the first tubular portion 311 and the second tubular portion 312 to bend.

As explained below, the cross-sectional view of FIG. 3 clearly shows the shape of the receiving surface. End-side receiving means each having semi-circular receiving surfaces 321 and 322 in a form coinciding with the outline of the circular gripping rods 21 and 22 can be identified. In the assembled state of the device of the present invention, the gripping rods 21 and 22 are located in the receiving surfaces 321 and 322, respectively, and the receiving surfaces 321 and 322 extend long. These gripping rods 21 and 22 are connected to the terminal bead 47 of the expansion lid 4.

The expansion cover 4 includes a first elastic outer portion 41 and an inelastic central portion 43 and a second elastic outer portion 42 adjacent thereto. The central portion 43 can be exchanged using a zipper. Therefore, the central portion 43 can be exchanged according to the function of a reflector, a diffuser, an optical filter, or the like which enables the apparatus of the present invention to be used for various purposes.

In the present embodiment, since the elastic outer parts 41 and 42 are made to have elasticity, the width of the expansion lid 4 is slightly shorter than the distance between the receiving surfaces 321 and 322. Thus, in order to be able to assemble the device of the present invention on the fly with only a few movements, the spreading rods 3 can be fixed against the elasticity of the expansion cover 4.
