Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a picture frame, and mainly relates to a rectangular frame formed by connecting a plurality of metal frame members at right angles to each other.

[Conventional technology]

Conventionally, this type of picture frame has been constructed by, for example, as shown in FIGS. 4 and 5, four edge frames 1 made of metal are butted against each other at approximately right angles at each end. An L-shaped connecting fitting 3 is superimposed on the inner side of the mounting piece 2 formed on the butt-butted edge frames 1, and screws 5 from the mounting piece 2 are screwed into the connecting pieces 4 on both sides of the connecting fitting 3. The picture frame main body A has a rectangular shape as a whole. In addition, a plurality of rubber packings 7 are housed at predetermined intervals in a recess 6 opened on the back side of each frame body 1 of this frame body A, and each rubber packing 7 is housed at a predetermined interval.
The edge of the glass plate 9 is locked to the locking step 8 on the inside of the glass plate 9, a presser plate 10 is brought into contact with the back surface of the glass plate 9, and the presser plate 10 is provided on the edge frame 1. There is a structure that locks with a locking piece 11.

(Problems to be Solved by the Invention) The conventional structure described above requires a large number of rubber packings 7 to elastically support the glass plate 9, and the rubber packings 7 are designed to fit the shape of the recess 6 of the edge frame 1. Therefore, it is necessary to prepare various types of rubber packings 7 suitable for various edge frames 1, and the glass plate 9 is elastically supported from the top, bottom, left and right by a large number of rubber packings 7. However, when the glass plate 9 moves, the glass plate 9
The edges of the corners collide with the threaded portions 5a of the screws 5 of the metal connecting fittings 3 that connect the edge frame body 1, and in some cases with the edges of the connecting fittings 3, and the impact causes There is a problem that it is often damaged due to contact.

Therefore, this invention was made in view of the above points,
With a shape that is not affected by the shape of each frame body of the frame body, the corner covering that can be used on various frame bodies protects the easily damaged corners of the glass plate, without using rubber packing. The purpose of this is to enable the glass plate to be safely set on the frame body.

(Means for solving the problem) The present invention forms a locking protrusion that locks the peripheral side of the glass plate from the back side on the inner peripheral edge of the frame main body formed in a rectangular shape, and this locking protrusion locks the peripheral side of the glass plate from the back side. The circumferential side of a square glass plate is locked from the back side to the stopper edge, and corner coverings are attached to each corner of the glass plate, and the corner coverings are made of transparent synthetic resin and are attached to the frame body. A fitting having a substantially L-shape in a size that can be fitted into the corner of the glass plate, and having a substantially U-shaped cross section that fits the corner of the glass plate on the inner side and covers the end surface and inner and outer surfaces thereof. It consists of a structure in which grooves are formed.

[Effect]

Since the present invention is constructed as described above, the corners of the glass plate are covered with corner coverings, so that even if the glass plate moves, the corners of the glass plate can be fixed to the connecting fittings. Since there is no direct contact with the screws and the corner cover is always present between them, damage to the glass plate is prevented.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 1 to 3. In this structure, the same parts as the conventional structure shown in FIGS. The reference numerals will be written and their explanations will be omitted.

In the figure, reference numeral 20 denotes a corner cover, and the corner cover 20 is made of a transparent synthetic resin and has a main body 21 formed into a substantially L-shape with a size that can be fitted into each substantially right-angled corner B of the frame main body A. On the inner side of the main body 21, clamping pieces 22 and 23 are formed integrally with each other in parallel and L-shape, and the opposing clamping pieces 22 and 23 hold the glass plate 9 at approximately right angles. A fitting groove 24 having a substantially U-shaped cross section is formed in an L-shape into which the corner portion 9a of the shape is fitted. The opposing parallel holding pieces 22 and 23 are thin enough to engage with a locking protrusion 25 formed on the inner peripheral edge of the frame main body A, and the bottom of the fitting groove 24 is It is formed thicker than each of the opposing clamping pieces 22 and 23. Locking protrusion 2 of the frame main body A
5 is formed at the inner end of the inner curved piece 26 in which the recess 6 is formed in each edge frame body 1.

In use with this structure, the corner coverings 20 are fitted to each corner 9a of the glass plate 9 via the fitting grooves 24 thereof. As a result, the corner covering 20 can be easily attached to the corner 9a of the glass plate 9, and the orthogonal end face portions of the glass plate 9 are brought into contact with the bottom of the fitting groove 24, and the opposing clamping The pieces 22 and 23 sandwich the inner and outer surfaces of the corner 9a of the glass plate 9.

Next, the glass plate 9 is attached to each edge frame body 1 of the frame body A.
When engaged from the back side with the locking protrusion 25 on the inside of the glass plate 9, each corner 9a of the glass plate 9 is locked via the clamping piece 22 or clamping piece 23 of the corner covering 20 attached thereto. It is engaged with the protruding edge 25. In this case, the locking protrusion 25 is provided so as to protrude inward from the inner surfaces of the mounting piece 2 and the connecting fitting 3 of the edge frame 1, so that the inner end surfaces of the mounting piece 2 and the connecting fitting 3 are used as guide surfaces. By pushing the glass plate 9 toward the front side through the corner covering 20, the clamping pieces 22 or 23 of the corner covering 20 are automatically engaged with the locking protrusion 25.

Further, an object to be mounted, such as a painting, is placed on the glass plate 9, a presser plate 10 is superimposed on the back surface of the object, and the presser plate 10 is locked with each locking piece 11. Thereby, the glass plate 9 is interposed and held between the locking protrusion 25 and the holding plate 10 via the corner coverings 20 at the four corners. In this case, since the clamping pieces 22 and 23 of the corner covering 20 are made of transparent synthetic resin, it is difficult to see through them from the front, and since they are formed thin, they are difficult to engage with the pressing support of the presser plate 10. A particularly noticeable gap does not occur between the stopper edge 25 and the glass plate 9.

Even if the glass plate 9 moves during handling or for other reasons and collides with the threaded portion 5a of the screw 5 fixing the connecting fitting 3 or the connecting fitting 3, each corner of the glass plate 9 A corner covering 20 is interposed between the screw 9a and the threaded portion 5a of the screw 5, and the bottom of the fitting groove 24 of the corner covering 20 is formed thickly, so that each of the glass plates 9 The corner portion 9a is protected and does not directly collide with the threaded portion 5a, etc., thereby preventing damage from the corner portion 9a.

[Effect of idea]

According to the present invention, the corner covering is formed into a substantially L shape, and a fitting groove having a substantially U-shaped cross section is formed on the inner side of the corner covering, so that the corner covering is inserted into the glass plate through the fitting groove. The workability is good because it can be easily attached to each corner of the glass plate, and since each corner of the glass plate, which is most easily damaged, is covered with a corner covering made of synthetic resin, its cushioning effect protects the corners. Since the corner covering is formed into an approximately L shape, it is not only easy to attach to each corner of the glass plate, but also can be easily attached to the square frame body. It is easy to set up and install the corner covering, and since the corner covering is made of transparent synthetic resin and attached to the corner of the glass plate, which is difficult to see from the outside, the corner covering is hardly visible from the front. The glass plate can be safely set without deteriorating the appearance, and therefore, the simple structure allows the glass plate to be set safely in various types of frame bodies without using a large number of special rubber packings.
