Alternatively, the present invention relates to a frame that is fixed to a wall surface in a train or the like and that houses a board-shaped advertising material.

[Conventional technology and its problems]

The above-mentioned picture frame is, for example, as shown in Fig. 1, made of a rectangular pipe frame, and has grooves on the inner peripheral surface of each side into which the periphery of the plate-shaped advertising material P is fitted over the entire length of the frame. 3, and is usually fixed to a wall surface with double-sided tape or the like, and the advertising material P is replaced in the fixed state. For this reason, this picture frame has a structure in which one side is separated to form a lid frame 1, and the lid frame 1 is connected to a fixed frame 2 consisting of the other three sides so as to be openable and closable.
The lid frame 1 is separated from the fixed frame 2 to open the end of the groove 3, and the advertising material P is taken in and out of the groove 3 from the open end of the groove 3 to be replaced.

This conventional connection structure, as shown in Figure 6,
A lid frame c is attached to a fixed frame d via an L-shaped bracket a and a screw b.
When performing the replacement work, the screw b is loosened, the lid frame c is removed from the fixed frame d as shown by the chain line in the figure, the exhibit P is replaced, and then it is fixed again with the screw b.

Therefore, it is necessary to align the screws b of the lid frame c with the screw holes of the fixing frame d each time, which is troublesome. Also, the screws b may come off the lid frame c and be lost.

Further, as a picture frame of this type that eliminates the above-mentioned trouble, there is an example of a picture frame in which a lid frame and a fixed frame are connected via a connecting tool called a latch piece, as described in Japanese Utility Model Application Publication No. 61-31258. .

This is a latch piece that is attached to the open end of a fixed frame and has a notch formed at the base end of a hook-shaped portion at the end of which the first and second control pins are respectively protruded from the end side. protrudes at right angles,
Further, control pieces for slidably controlling the latching pieces are respectively fixed inside the tip of the open end of the fixed frame,
A guide groove and a stopper groove are formed along the center longitudinal direction, separating the spring piece with one end open, and a stopper part is formed at the tip of the control piece, and the latching part is formed at the tip of the control piece. The first and second control pins provided on the control piece are slidably engaged in the guide groove of the control piece.

However, this connection structure between the lid frame and the fixed frame is complicated and often breaks down.

Further, due to its structure, it must be made of metal material, resulting in high cost.

Therefore, this invention takes into account the above-mentioned drawbacks of the conventional technology, and by pulling out the lid frame without removing screws or the like and removing it from the fixed frame, the work of replacing advertising objects can be done easily and quickly.
To provide an inexpensive and trouble-free picture frame as a whole by simplifying the connection structure between a lid frame and a fixed frame using a material such as resin.

[Means to solve the problem]

In order to solve the above problem, in this invention, a groove into which the periphery of the plate-shaped advertising object is inserted is provided over the entire length of the inner peripheral surface of each side of the rectangular pipe frame. In the provided picture frame, one side is cut off to form a lid frame 1, and the other three sides are used as a fixed frame 2, and one support piece 8 of an L-shaped member 7 made of an elastic material is attached to both ends of the lid frame 1.
At the same time, the other piece 11 is made into a bifurcated elastic piece by forming a crack 12 opening on the front and rear sides of the frame from the tip to the rear end, and a recess 13 is formed in the opening edge of the crack 12. On the other hand, a sliding member 15 is fitted into both open ends of the fixed frame 2 so as to be slidable in the length direction of the fixed frame 2, and the protruding end of the sliding member 15 is connected to the other bifurcated piece of the L-shaped member 7. 11, and the protruding end and the other piece 11 are formed with a bearing hole 14 and a shaft protrusion 16 that are perpendicular to the longitudinal direction of the frame that are fitted into each other. 16, the sliding member 15 is rotatably supported on the other piece 11 in the front-rear direction of the picture frame. The fixed frame 2 has a locking protrusion 18 on the extension line that fits into the recess 13 of the other piece 11 when the lid frame 1 is in contact with the fixed frame 2. The sliding groove 17 of the sliding member 15 has a length that allows the lid frame 1 to rotate in the front-rear direction of the picture frame with the locking protrusion 18 in contact with the rear end of the sliding groove 17. The structure was designed to do so.

[Effect]
