Description

The present invention relates to a frame structure for holding and displaying various display objects having different thicknesses.

In the conventional frame structure, the back plate is removed from the back surface of the frame body, the display object is placed inside the frame body from the back side, and then the back plate is fitted into the original position of the back surface of the frame body. It has been known that the display object is held so as to be sandwiched between the frame body and the back plate (for example, Patent Document 1).

13 and 14 are views to be referred to for explaining the conventional frame structure 2.

As shown in FIGS. 13A and 13B, the conventional frame structure 2 includes a main body member 4 and a back plate 6 provided on the back side of the main body member 4.

As shown in FIG. 13A, the main body member 4 of the frame structure 2 is formed in a substantially quadrangular plate shape, and on the back surface side thereof, the outer shape is smaller than the main body member 4 as shown in FIG. The substantially quadrangular arrangement portion 4a was formed so as to be recessed in the thickness direction of the main body member 4 from the back surface side to the front surface side of the main body member 4, and the edge portion 4b was formed so as to surround the outer shape of the arrangement portion 4a. ..

Then, in the arrangement portion 4a of the main body member 4, a substantially quadrangular display window portion 4c whose outer shape is smaller than the arrangement portion 4a is formed as an opening that penetrates the arrangement portion 4a in the thickness direction at the substantially central portion thereof. The frame portion 4d was formed so as to surround the periphery of the display window portion 4c.

Then, as shown in FIG. 13B, a plurality of (8) locking pieces 8 formed in a substantially elliptical plate shape having an elongated outer shape are provided on the back surface side of the edge portion 4b of the main body member 4. Was being done.

One portion (mounting portion) of these locking pieces 8 in the length direction is attached to the edge portion 4b by a wood screw or the like, and the locking piece 8 is oriented in the length direction with this mounting portion as an axis. The other part (holding part) could be rotated.

Then, as shown in FIG. 13B, a predetermined length is formed on the left and right sides of the arrangement portion 4a of the main body member 4 on the back side of the left side side and the right side side edge portion 4b formed along the vertical direction. Both ends of the hanging string 9 having a sword were attached.

As shown in FIG. 13B, the back plate 6 of the frame structure 2 is formed in a substantially quadrangular plate shape whose outer shape is slightly smaller than the arrangement portion 4a of the main body member 4, and as shown in FIG. The back plate 6 can be arranged so as to be loosely fitted to the arrangement portion 4a formed so as to be recessed from the back surface of the main body member 4.

The thickness dimension of the back plate 6 is formed to be smaller than the depth dimension from the back surface of the main body member 4 to the arrangement portion 4a, and when the back plate 6 is fitted to the arrangement portion 4a, the back surface of the back plate 6 is formed. Was prevented from protruding from the back surface of the main body member 4.

Then, in a state where such a back plate 6 is fitted to the arrangement portion 4a of the main body member 4, the locking piece 8 is rotated so that the holding portion is located inside the arrangement portion 4a ( (See FIG. 13B), the back plate 6 is locked so as not to come off from the arrangement portion 4a.

Then, by rotating the locking piece 8 so that the pressing portion is located outside the arrangement portion 4a (see FIG. 14), the back plate 6 in a state of being fitted to the arrangement portion 4a is attached to the main body member 4. It was designed to be removable from the back of the.

When holding the display object 1 by using such a conventional frame structure 2, first, all the locking pieces 8 provided on the edge portion 4b of the main body member 4 are arranged by the holding portion of the main body member 4.

However, in the conventional frame structure 2 as described above, there is a problem that the display object cannot be easily exchanged because the work of exchanging the display object in the frame takes time and effort.

That is, in the conventional frame structure 2, when the frame is hung on the wall surface, the frame is once removed from the wall surface, the back plate 6 is removed from the back surface of the main body member 4, and the display object 1 is replaced. It had to be replaced, and the replacement work was very complicated.

Further, in the conventional frame structure 2, the thickness dimension of the display object 1 capable of holding the frame is determined, and the display object 1 having other thickness dimensions may be thin or thick. There was also the problem that it could not be held normally.

For example, when a very thin display object 1 such as a piece of paper is arranged inside the frame, a gap is generated between the back plate 6 sandwiching the display object 1 and the arrangement portion 4a of the main body member 4. As a result, the position of the display object 1 may shift, or the display object 1 may be bent and wrinkled.

On the contrary, when a thick display object 1 such as a multi-page booklet is arranged inside the frame, the back surface of the back plate 6 sandwiching the display object 1 greatly protrudes from the back surface of the main body member 4. The back plate 6 could not be locked by rotating the stop piece 8, and if the locking piece 8 was moved in an attempt to forcibly press it, the locking piece 8 might be damaged.

In this way, the conventional frame structure 2 is premised on the usage of holding a display object such as a picture or a photograph whose thickness does not change so much and displaying it for a relatively long period of time. Therefore, it was not intended to hold various display objects with different thicknesses or to frequently replace the display objects in a short period of time.

On the other hand, with the development of the publishing and advertising industry and the development of printing technology in recent years, highly artistic works (for example, product catalogs, pamphlets, magazines) that take design into consideration in various situations in various industries. (Covers, etc.) have come to be created in large numbers, but when a person who has such a work wants to display them on a frame, the conventional frame structure 2 is sufficient to meet the demand. Could not meet.

In addition, even when a single person uses the frame, there has been a long-standing demand for more casual display of hand-drawn illustrations and photographs taken with a digital camera and printed with a printer, and from that perspective. However, the conventional frame structure 2 could not sufficiently satisfy the requirement.

Therefore, in view of the above problems, it is an object of the present invention to provide a frame structure capable of easily and quickly exchanging display objects and holding display objects having different thickness dimensions. Is what you do.

By doing so, it is assumed that the user side of the frame will be provided with a new opportunity to display various works beyond the conventional concept of the frame structure, and that the provider side of the work will also be exhibited.
