Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a simple picture frame mainly made of aluminum or other lightweight alloys.

(Prior Art) Conventionally, as shown in Fig. 4, a frame piece b 4 is provided with a groove a for inserting a mount or the like on its inner surface and has both ends cut out at 45 degrees.
The book is assembled into a rectangular frame with both edges abutted, and each leg c-1 of the L-shaped binding device c is inserted into the end of each frame piece b that is abutted against each other, and each leg c- 1 is tightened and fixed to each frame piece b using screws d, respectively.

(Problem that the invention attempts to solve) However, this one has a screw hole e provided in the leg c-1.
It is difficult to match the screw hole f provided in the frame piece b with the screw hole f provided in the frame piece b, and it is inconvenient that it takes time to assemble it.

Therefore, as shown in FIG. 5, a groove f along the frame piece b that opens at both edges was provided at each end of the frame piece b, and a groove f was provided on each leg c-1 of each L-shaped fastener c. Screw hole f
A screw d is applied in advance to the end of each frame piece b, and when each leg c-1 is inserted into the end of each frame piece b, the screw d is inserted through the groove f, and then the screw d is tightened. It is conceivable to connect the two frame pieces b and b to each other, but in this case, the tightening position of the screw d is not restricted, and as shown in FIG. It is predicted that problems that will occur and spoil the appearance will occur.

The object of the present invention is to provide a picture frame that is free from such defects and can be easily assembled.

(Means for Solving the Problems) In order to achieve the above object, the present invention creates a rectangular shape by abutting four frame pieces with insertion grooves on the inner surface and notches at both ends at an angle of 45 degrees. The legs of the L-shaped fasteners are inserted into the ends of the frame pieces that are assembled into the frame and are abutted against each other, and each leg is tightened and fixed to each frame piece with screws. Each leg of each fastener is provided with a protrusion, and each leg of each frame piece is provided with a through hole of approximately the same size into which the protrusion fits, and each end of each frame piece is provided with a through hole of approximately the same size as the protrusion. A groove is provided along the frame piece that is open at both ends.

(Function) When doing this, place a screw in advance into the screw hole made in each leg of the binding device, and in this state, fit each screw into the groove made in each frame piece. By inserting the legs into each frame piece, then tightening the screws with the protrusions on each leg fitted into the through holes, the position of each fastener relative to each frame piece is determined. The frame pieces 3 can be assembled into a rectangular frame without mutually shifting their positions.

(Example) Embodiments of the present invention will be described with reference to the attached drawings.

In the drawings, reference numeral 1 designates a rectangular frame formed by abutting both edges of four frame pieces 3, each of which has a slot 2 for inserting a mount or the like on its inner surface and has both ends cut out at 45 degrees. Each leg 4a of an L-shaped fastener 4 is fastened to each frame piece 3 with a screw 5 at the end of each frame piece 3 to be butted, and each frame piece 3 is fastened and fixed. The configuration up to now is not particularly different from what is conventionally known.

In such a device, the present invention provides a protrusion 6 on each leg piece 4a of each fastener 4, and also provides a protrusion 6 on each frame piece 3.
A through hole 7 having a size approximately equal to the outer periphery of the projection 6 into which the projection 6 is fitted is provided at each end of the frame piece 3.
A groove 8 along the frame piece 3 opening on both edges at each end of the
This will be described in more detail with reference to the embodiment shown in FIGS. 1 and 2. Each frame piece 3 is formed of a groove-shaped material consisting of an arcuate plate 3a on the front side and a flat plate 3b on the back side. Frame pieces 3 are installed at both ends of the flat plate 3b.
A long groove 8 is formed along the longitudinal direction, and a through hole 7 having a size substantially equal to the outer circumference of the projection 6 into which the projection 6 provided on the leg piece 4a is fitted is formed in a part of the long groove 8. The binding tool 4 is formed into an L-shape by punching out a flat plate into an L-shape, forming legs 4a, 4a along the inside of the flat plate 3b, and has a hemispherical protrusion 6 on one side thereof.
, and a screw hole 9 into which the screw 5 is inserted. Thus, the screw 5 is installed in the screw hole 9 in advance, and in this state, the threaded part 5 of the screw 5 is inserted into the groove 8.
If the screws 5 are tightened after inserting each leg 4a into the end of each frame piece 3 while inserting the protrusion 6, the protrusion 6 will naturally fit into the through hole 7 and close to each frame. The position of each fastener 4 with respect to the piece 3 is determined, and each frame piece 3
are assembled in a rectangular frame 1 without mutual displacement.

As shown in FIG. 3, the protrusion 6 provided on the binding tool 4 may be provided with a tapered bar ring on its leg 4a, and the outer circumference of the protrusion 6 may be applied to this. It is also possible to form the screw hole 8 by applying the same.

Further, in the illustrated example, the groove 8 and the through hole 7 are provided so as to communicate with each other, but it goes without saying that they may be provided separately.

(Effect of the invention) As described above, according to the present invention, in order to provide each end of each frame piece with a long groove that opens on both edges, screws are attached to the fastener in advance, and in this state, both ends of each frame piece are attached with screws. Each leg of the binding device can be inserted into the
Screw fastening work becomes easy, and by fitting the protrusions into the through holes, the positions of each frame piece and each fastener can be determined accurately, and the appearance can be adjusted without shifting the position of each frame piece. It has the effect of being able to form a good framework.
