Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a picture frame assembled into a frame shape using corner connecting fittings.

(Prior Art) When connecting the corners of a conventional picture frame, as shown in FIG. An L-shaped connecting plate 4 having screw holes is attached to the inner surface of a hollow mounting edge 3 having a narrow opening 2 in the length direction, and four screw holes located in the opening 2 of the mounting edge 3 are attached. The screws 5 are screwed into the upper surface of the hollow mounting rim 3 respectively, and the mounting rims 3 of the pair of frame pieces 1 forming the corners of the frame are tightened and fixed to both pieces of the L-shaped connecting plate 4. A structure was adopted in which the frames were connected and fixed to form a picture frame.

(Problems to be solved by the invention) When using the conventional picture frame structure as described above,
When connecting the four corners with connecting fittings, it is necessary to screw in at least four screws in one place, which makes the connection work complicated, and there are also problems such as requiring a large number of screws and being small, making them easy to lose. .

The object of the present invention was made in view of the above-mentioned problems, and is to provide a picture frame in which the work of connecting picture frame pieces is easy and can be done quickly without using a large number of screws.

[Structure of the idea]

(Means for Solving the Problems) The picture frame of the present invention has a hollow mounting rim that forms one side of the frame main body and is formed along the inner periphery, and a narrow opening parallel to the length direction on the outer surface of the hollow mounting rim. an L-shaped connecting plate in which both pieces are inserted into the hollow mounting edges of a pair of frame pieces formed at a substantially right angle by abutting the end surfaces of the hollow mounting edges; and the L-shaped connecting plate. a lever rotatably pivoted on at least one side of the lever and abutted on the outer surface of the hollow mounting edge, and the narrow opening is opened on both sides of the pivoted portion in the width direction of the lever. It is formed by forming small protrusions located inside the portion and on the outer surface of the mounting edge.

(Function) In the picture frame of the present invention, when the end faces of a pair of frame pieces are brought together to form a substantially right-angled corner, at least one of the hollow mounting edges formed inside both picture frame pieces has an L-shaped Position and insert the pivoting part of the lever that is pivoted on the connection plate into the opening of the hollow mounting edge, and after aligning the end faces of the frame pieces to form a substantially right angle, rotate the lever so that it protrudes from the bottom surface of the lever. The small protrusions are strongly crimped onto the outer surface of the hollow mounting edge, and one piece of the L-shaped connecting plate is fixed to the frame piece.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 3.

6 is a frame piece that constitutes the four sides of the frame body;
Both ends are cut at a 45° angle. A hollow mounting edge 7 with a rectangular cross section is provided on the inner peripheral side of the back surface of this frame piece 6.
is formed over the entire length, both ends of the mounting edge 7 are open, and furthermore, a narrow opening 9 is formed over the entire length at the center of the width direction of the mounting plate portion 8 on the outer surface of the mounting edge 7. 10 is an L-shaped connecting plate bent at right angles on the same plane, one piece 11 has a pair of screw holes 12, 12 formed at intervals in the length direction, and near the end of the other piece 13, A plate-shaped lever 14 is rotatably attached to a support shaft 16 having a flange 15 in the middle. Then, the connecting plate 10 and the flange 15
There is a gap in between into which the mounting plate portion 8 of the frame piece 6 is inserted. One end of the support shaft 16 is engaged with the lever 14 via a washer 17, and the other end is engaged with the connection plate 10 by caulking.
Furthermore, small protrusions 18, 18 are formed on both sides of the shaft attachment part of the lever 14 in the width direction, and bulge downward under pressure and protrude below the flange 15.
A small operation protrusion 19 is formed on the surface of the lever 14 on the side opposite to the shaft attachment part in the length direction.

Next, in order to connect a pair of frame pieces 6 using this L-shaped connecting plate 10 and lever 14 to form a frame body, first cut the end of the hollow mounting edge 7 of one frame piece 6 at 45 degrees. Screw hole 12 of L-shaped connection plate 10
One piece 11 of the L-shaped connecting plate 10 is attached to one frame by screwing screws into the screw holes 12 and 12 through the narrow opening 9 of the mounting plate part 8 and tightening them. Fix it to piece 6. Next, move the lever 14 to the first position.
As shown in the figure, the small protrusions 18, 18 are rotated so that they are parallel to the narrow opening 9 of the mounting edge 7 of the other frame piece 6, and the flange 15 of the support shaft 16 and the connecting piece 10 are The other piece 13 of the L-shaped connecting plate 10 is inserted so that the mounting plate part 8 is inserted into the gap between the other piece 13 and the other piece 13.
When the other piece 13 is pushed into the hollow mounting edge 7, the small protrusions 18, 18 protruding from the lower surface of the lever 14 protrude into the narrow opening 9 of the mounting plate 8 and do not get in the way. It is inserted into 7. Then, when the connecting end surfaces of the frame pieces 6 cut at 45 degrees are brought together and the lever 15 is rotated in a direction parallel to the narrow opening 9, the levers 14 located on both sides of the support shaft 16 are rotated. The small protrusions 18, 18 on the lower surface ride on the upper surface of the mounting plate part 8 and are strongly pressed against the mounting plate part 8, and the mounting plate part 8 is strongly fastened between the L-shaped connecting plate 10 and the small protrusions 18 of the lever 14. The other piece 13 of the L-shaped connecting plate 10 is fixed to the other frame piece 6. In the same manner, other frame pieces 6 are connected in sequence to form a frame body.

In the above embodiment, one piece 1 of the L-shaped connecting plate 10
1 is screwed and a lever 14 is pivotally attached to the other piece 13, but it is also possible to fix the lever to the frame pieces 6, 6 by operating the lever by pivoting the lever on both pieces 11, 13.

[Effect of idea]

According to the present invention, the picture frame pieces can be connected by rotating the lever, so the connection work is faster and easier than with conventional screw fastening, and when inserting the connecting plate, the small protrusion of the lever can be attached to the mounting edge. By positioning it in the narrow opening of the frame, the connecting plate can be pushed in smoothly without the small protrusion getting in the way, and by rotating the lever and pressing the small protrusion onto the outer surface of the mounting edge, the mounting edge of the frame piece can be pushed in smoothly. is strongly fastened between the small protrusion and the L-shaped connecting plate, so that the L-shaped connecting plate can be reliably connected to the frame piece.
