Description

[Detailed Description of the Invention] The present invention relates to a picture frame, and more particularly to a picture frame that can hold documents, photographs, etc. and be hung on a wall.

Previously, picture frames were mainly used to inlay Western-style paintings and hang them on the wall to enhance the content of the paintings. Since conventional picture frames were intended for aesthetic viewing, emphasis was placed on aesthetics rather than practicality, sturdiness was not an issue, and many were expensive.

Unlike previous picture frames, this frame can be displayed in places where large numbers of people gather, such as pachinko parlors, and can mainly be used to display commercial information such as advertisements for products.
The present invention provides a practical picture frame that is used to provide media such as photographs and paintings to the public, has a simple structure, is strong, and can withstand frequent replacement of displayed items. Another advantage of the present invention is to provide an inexpensive picture frame that is extremely simple to manufacture using minimal materials and processing, without the need for decoration.

The applicant of the present application first developed an economical picture frame that could be assembled using flat steel plates and angle iron with a simple structure and was manufactured at low cost. It was published in Publication No. 60-2853. The present invention relates to an improvement of the invention described in the above-mentioned application.

The purpose of this invention is to provide a frame that can be assembled using angle iron only, and to make it easy and quick to attach and remove documents, photographs, etc., and to make it convenient and simple when frequently replacing documents and photographs on display. The object of the present invention is to obtain a picture frame that can be manufactured at a lower cost by using the above structure.

The above object of the present invention is to direct one leg of the L-shape at an angle of approximately 90 degrees toward the heel of the angle iron in each of a plurality of angle forming portions selected along the length of the angle iron having an L-shaped cross section. After bending it, connect both ends to form a closed corner ring, and make L at each corner.
The other leg of the letter is welded smoothly after removing the wrinkling portion generated in this part to form a rectangular frame having a uniform L-shaped cross section over the entire circumference, and the rectangular frame. A locking fitting 2 that projects from the one leg of each of the two mutually opposing sides to the bosom of the angle iron to hold the document in a predetermined position.
and a mounting bracket that is attached to one side of the rectangular frame that is positioned at a high level when the main body part 1 is hung on the wall and that is latched to a receiving material on the wall. achieved.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

Referring to FIG. 1, there is shown a picture frame 10 of the present invention having a main body portion 1 consisting of a closed square annular frame formed by bending an angle iron 4 of a predetermined size into a rectangular shape and connecting both ends thereof. has been done. Specifically, three or four corner forming portions are selected in advance at a predetermined interval along the length of the angle iron 4 of a predetermined length, and the first leg 4A forming an L-shaped cross section is attached to each corner forming portion. 90 towards the bosom part 5 of the angle iron 4.
The two ends are bent at the same time and connected by welding to form a rectangular ring-shaped frame. Next, after removing the wrinkled portions that occur in the second legs 4B having an L-shaped cross section at each corner, the second legs 4B are welded to be continuous with each other. The parts connected by welding shall be finished smooth. In this way, the lower edge of the first leg 4A, which has an L-shaped cross section over the entire circumference, hits the wall of the room and is attached thereto, and the second leg 4B is arranged parallel to the wall, and the bosom portion 5 of the angle iron 4 is The main body part 1 consists of a rectangular frame configured to come into contact with the edges of the four circumferences of calligraphy, paintings, and photographs (not shown) stored in the
is formed. A locking fitting 2 made of a band-shaped steel plate is placed on the foot portion 5 of the angle iron 4 parallel to the second leg 4B at a predetermined distance from the second leg 4B, and one vertical edge portion is welded to the first leg 4A of the angle iron 4. It is fixed by etc. As shown in FIG.
By making the posted items slightly smaller than the sum of the width a and the width a, these posted items can be easily pushed into the gap between the second leg 4B of the angle iron 4 and the lock fitting 2. If the posted item is slightly moved to the center position of the two locking fittings 2, 2, both locking fittings 2,
It is possible to keep it from falling out of 2. As shown in Fig. 1-4, one half 3 of a mounting bracket such as a hinge is attached to the lower end of the first leg 4A on one side of the rectangle of the main body portion 1, and is positioned on a frame 8 attached to a wall or the like in the room. It is designed to fit into the other half 3' of the hinge fitting (the fifth
(see figure). As the mounting fitting, in addition to a hinge fitting, a simple eye fitting may be attached to the edge of the first leg 4A of the angle iron 4 and hung on a fitting such as a nail provided on the wall of the room. As shown in FIGS. 2-3, a short washer 6 is attached parallel to the locking fitting 2 on the other side of the main body portion 1 opposite to the side on which the hinge fitting 3 is attached. A locking hook 7 (see FIG. 5) attached to the wall side is engaged with the washer 6 to lock the frame 10 in the position attached to the wall.

FIG. 5 shows an embodiment in which an underframe 8 is attached to the wall side when the picture frame 10 of the present invention is attached to the wall of a room, and the underframe 8 is provided with a right-angled flange 8F at the upper end.
This flange 8F is attached to the upper part of the wall so as to come into contact with the horizontal upper surface of a horizontal member, etc., and the fold 8C of the flange 8F has a mating part that is fitted into one half 3 of the hinge fitting. The other half 3' of the hinge fitting is attached. The underframe 8 has an opening 11 formed by hollowing out the central main part, and right-angled flanges 9 are attached to the four circumferences of the opening 11.
It serves as a stiffener for the underframe 8. In this embodiment, the frame 8 plays an important role as a doorstop material because the frame 10 operates like a swinging door that rotates around the hinges 3, 3'. A rotating locking hook 7 is attached to the lower edge of the opening 11 of the underframe 8. 7H indicates the handle of the locking hook 7. The device of the present invention can be made into an extremely beautiful frame by applying chrome plating to the main portion made of steel or by using stainless steel.

When using the device 10 of the present invention, it may be removed from the wall of the room, but if it is rotatably attached to the wall as shown in Fig. 5, it may be tilted appropriately to the wall to display calligraphy, paintings, photographs, etc. A pair of locking fittings 2,
It can be easily removed by tilting one of the metal fittings 2 deeply. Further, by similar operations, new calligraphy, drawings, photographs, etc. can be inserted into the frame extremely quickly and easily. After being fitted, if the posted item is slightly returned to the center position between both locking fittings 2, 2, there is no risk of it slipping out.

The picture frame 10 of the present invention is extremely suitable for handling not only ornamental calligraphy and paintings displayed in pachinko parlors, but also commercial calligraphy, paintings, photographs, and other objects that are frequently replaced.

The effects of the present invention are as follows:

(1) Since it is manufactured only from angle iron, the material and labor costs are extremely low and economical.

(2) Because it does not use wood like in the past, it is extremely durable and will not be damaged even if the calligraphy and paintings are frequently replaced.

(3) The handling, especially the loading and unloading of calligraphy and paintings, is extremely simple and quick, which helps improve work efficiency.

(4) It does not move after being hung on the wall. In particular, when the frame is pre-installed on the wall, the frame is securely locked and held in a stable state.
