Abstract

For example, it is possible to easily connect and separate foam-like single plates made of foam material, which is a reflective plate generally used in photography such as photographs and videos, and to efficiently create a large reflective surface. A foam board connecting clip is provided.
A substantially square plate material of long pieces and short pieces is subjected to bending processing, and is combined to form a substantially “U” -shaped sandwiching member. The sandwiching member is narrowed toward the “U” -shaped opening so that the width is narrowed. From the middle, the sandwiching member is gently folded back so that the distal end of the sandwiching portion is located outside both sides of the base end. The two clamping members are connected to each other via a hinge.

Description

The present invention relates to board connection.

For example, in the field of photography such as photography and video, a board made of foam material is used as a reflector so as to reflect light and adjust shadows to obtain an optimal image.

Such a reflector may change in size depending on the subject to be photographed. For example, a large subject such as a person or furniture often needs a large reflecting surface to cover its size. In FIG. 1a, two thick foam boards indicate adhesive tape so that the thick black line indicates an adhesive tape. Used for pasting. The form of use is generally a “<” shape so as to be self-supporting and placed near the subject.

A number of conditions are required for pasting foam boards using conventional adhesive tape. At first, we will learn how to paste foam boards that are not always cheap and often fail.
One of the conditions is related to how the adhesive tape is applied, and each single surface should be movable as if the foam boards were joined together with a hinge. This is because the reflector is shaped like a letter “ku” so that it can stand on its own without a tripod or other stop, allowing the distance to the subject to be freely changed and the angle of opening to be adjusted. Therefore, the amount of reflected light can be adjusted depending on the degree of opening.
Secondly, the joined foam boards are strong enough to maintain their weight, twist, vibration, wind, etc.

This seemingly simple bonding process is actually very difficult and requires considerable experience and know-how. The reason is that the foam material is fragile and cannot be re-applied many times because there is a risk that the foam material may be peeled off when it is in close contact with the adhesive tape. In other words, a technique that can be applied accurately at one time is required.
And because of its vulnerability, once bonded, it is almost impossible to peel off the adhesive tape after shooting and return it to the original single board. However, there are many cases where a single foam board that is not bonded together is necessary at the shooting site, and for that purpose, there are several other foam boards that have the same shape as those used for bonding. .

Two clip-shaped holding members having long and short pieces facing each other are provided, and the two holding members are connected to each other by a hinge. Narrowing toward the tip of the part, having a bent part in the middle of the long piece and short piece, the tip of each clamping part is located outside both sides of the clamping member base end, and the tip of the short piece is It has the characteristic of being located at substantially the same height as the bent part of the long piece.

Therefore, the present invention pays attention to this point, and provides a board connection clip that makes it easy for anyone to connect and separate foam boards, and reduces storage space and economical negative.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 2, a plate having a substantially square shape and different height is used. This plate has a circular arc at both ends of the upper portion and three elongated cutout portions at the lower portion. The upper arc is for safety, and the lower hole is for passing three bolts for joining with the folding hinges. A metal plate considering the bendability and rigidity is suitable for the plate material, and the folding hinge is preferably a large and strong one with a side of about 4 × 8 cm because it also relates to the rigidity of the present invention.

The two long and short metal plates are bent in the same manner as shown in FIG. 3, but the width of d which is the bottom of the sandwiching member is set to be the thickness of the foam board used or slightly wider than that, and the bending angle is A slight acute angle such as e is made so that the space sandwiched by the sandwiching portion gradually narrows toward the tip. A pair of the long and short plates are combined to form a sandwiching member having a substantially “U” shape as shown in FIG. Note that the standard of the angle e at which the base end portion of the plate material is bent is such that the narrowed portion p width is substantially less than 2/3 of the base end portion h width. Further, in order to smoothly insert the foam board, the distal end of the sandwiching portion is gently bent so as to be outside of the side surface of the base end portion as shown by f to form the insertion guide portion s.

Two clamping members are prepared and connected to each other through a folding hinge as shown in FIG. At that time, the opposing clamping members are joined so as to be inversely symmetric as shown in FIG. This is a plan view of the state in which the clip of the present invention is folded. FIG. 7 shows a cross section of the foam board, the hatched portion indicates a part of the foam board is omitted, and the circled area indicates the corresponding portion. As described above, the tip of the short piece enters into the upper bent portion of the long piece so that the tip portions do not interfere with each other, so that even if the board is folded while being connected, it can be stored compactly.

FIG. 8 is a plan view showing a state in which the foam board is inserted and held in the sandwiching member, the hatched portion shows the cross section of the foam board, the wavy lines show a part of the foam board omitted, b and c are before the foam board is inserted, bb and cc indicate the state of the sandwiched member after insertion, and the direction lines of the front each schematically indicate the elastic energy of the foam board and the sandwiched member, so that the pressed foam board has the narrowed portion g point and o point. As the action point, the periphery of the part is pushed in and contracts, but at the base end, the shape returns to the original shape. On the contrary, the holding member is expanded with the openings at points g and o like bb and cc. As a result, elastic energy is generated in each member so as to return to the original shape as schematically indicated by the direction lines r and t, and the foamed board is sandwiched and held by using the opposite energy. When the pinching force is weakened, the pinching force is restored by holding the tip of the pinching member by hand and crushing it appropriately in the direction of narrowing the width of the opening.

As shown in FIG. 9, the connecting clip can be easily attached and removed by simply pushing it in from the top with the foam board stacked, and removing it simply by pulling it out. In addition, many of the reflectors for photography have different colors, such as “white, black”, “white, silver”, and “white, gold”, and reflect the reflectance and color to the subject and image. In general, the present invention, which uses folding screen hinges, can easily change the front and back surfaces by simply turning it back, and requires a quick response. It works effectively.

As shown in FIG. 10, a relatively small subject such as clothing can be made with a small reflector so that the clip of the present invention can be handled with a single k as shown in FIG. 11, and a large foam board such as a kimono is used as shown in FIG. When doing this, use the clip of the present invention one by one on the top and bottom of the foam board as in l (el) to stabilize.

When a larger reflecting surface is required as shown in FIG. 12, a plurality of 3 × 6 or 4 × 8 size foam boards can be connected by using an appropriate number of the present invention clips such as m. . In addition, as shown in Fig. 9, the installation of the present invention can be done in a simple and short time by simply inserting the foam board from above, so that it can be used not only as a reflector but also as a simple partition or exhibition space booth. Can also be expected.
