BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a frame of a frame used for decorating a painting, a poster, a jigsaw puzzle, or the like.

[0002]

2. Description of the Related Art Conventionally, various structures have been proposed for a frame frame in which a plurality of frame members are connected via a connecting tool. Further, in this kind of frame, it is desired that the front panel can be attached and detached by rotating the frame member so as to facilitate the exchange of the posted matter. Therefore, as a frame frame structure in which the frame member is rotatable, a frame member having a groove for fitting the connector in the connector is rotatably mounted, and the protrusion of the connector is the frame member in the longitudinal direction. There is also proposed a structure in which it is locked in a groove formed at a right angle (Japanese Utility Model Publication No. 1-179566).

[0003]

[Problems to be solved by devising]

In the above-mentioned conventional technique, since the connector is directly mounted in the groove formed in the frame member, it is suitable for a metal frame member, but a connector member such as a wooden frame member is mounted. It cannot be applied to a frame made of a material in which it is difficult to form a groove for use.

[Means for solving problems]

A frame frame of the present invention is a frame frame formed by forming a plurality of frame members into a polygonal shape through a connecting tool.
A locking member is attached to the lower portion of the frame member, and a mounting portion and a locking portion for a connecting tool are continuously provided to the locking member, and the mounting portion is rotatably mounted on an edge portion of the connecting tool, The locking portion is configured to be removably locked to a locking portion formed inside the connector. According to the first aspect of the invention, the connecting member formed on the locking member is used.
The attachment part to the knot is a mounting rod, and this mounting rod is the groove of the coupling.
In the invention of claim 2, the connecting part to the connector is formed into a groove.
Then, this groove is attached to the attachment rod of the connecting tool. Claim 3
Of the invention relates to the stopper structure, the locking part is parallel to the frame material.
It is a ridge, and the closing stopper is composed of two opposed projecting pieces.
Then, the ridge is elastic between the ridges that form the closing stopper.
It has been mechanically locked. As a material of the connecting tool, a metal or a synthetic resin is generally used. Further, although the present invention is suitable for a wooden frame material, it can also be used for a metal or synthetic resin frame material.

[0006]

The frame member and the connecting tool are rotatably connected to each other via the locking member attached to the lower portion of the frame member. Therefore, it is not necessary to provide a connecting groove in the frame member, and even a wooden frame member can be rotated. Further, since the locking member is provided with the locking portion and can be engaged with and disengaged from the locking portion of the connecting member, the frame member can be assembled in a stable state.

[0007]

EXAMPLES Next, examples will be described. Wooden frame material 1
A locking member 2 is attached to the lower part of the. Although this mounting method may be performed by screwing, an example in which the dovetail groove 3 formed in the locking member is fitted and fixed in the dovetail groove 3 formed in the frame member 1 is shown in the drawing.

The locking member 2 has an outer wall 2 inside and outside the upper wall 2a.
This is a configuration in which b and the inner wall 2c are vertically connected. A mounting rod 5 having a circular cross section is connected to the lower end of the outer wall 2b, and a locking projection 6 is connected to the lower end of the inner wall 2c. A guide groove 7 is formed on the inner wall 2c at 45 degrees with the shaft.

On the other hand, the connecting member 8 is provided with two mounting rod mounting portions 10 projecting along two edges of the base plate 9 having a right-angled triangular shape in a plane and sandwiching the right angle. The mounting rod mounting portion 10 is configured such that the projecting pieces 10a and 10b are opposed to each other with the upper portions squeezed, and the mounting rod 5 is rotatably mounted in the groove between the projecting pieces 10a and 10b. I am doing it. In the figure, reference numeral 11 is a support for the mounting rods provided between the mounting rod mounting portions 10, and the upper surface thereof has a concave arc shape in cross section corresponding to the mounting rods 5.

On the inner side of the mounting rod mounting portion 10 of the base plate 9, a closing stopper 12 is provided so as to project. The structure of the closing stopper 12 is the same as that of the mounting rod mounting portion 10 so that the locking projection 6 continuous with the locking member 2 is elastically locked between the opposing protruding pieces 12a and 12b. There is.
A sliding prevention stopper 13 is provided on the base in a protruding manner, and the sliding prevention stopper 13 is engaged with a guide groove 7 formed with an inner wall 2c of the locking member. Reference numeral 14 in the figure denotes a support for the locking projection 6.

In this embodiment, the closure stopper 12
Since the locking projections 6 of the locking member 2 can be freely engaged and disengaged, the frame member 1 can be rotated outward about the mounting rod 5 as required. Further, since the rotation shaft can be positioned as low as possible, contact between the end portions of the frame material during rotation hardly occurs. Further, since the lower end portion of the side wall 1a of the frame member abuts on the mounting rod mounting portion 10, excessive rotation is prevented.

4 to 6 show modified examples of the mounting structure of the locking member 2 attached to the frame member 1 and the connecting member 8. That is, in FIG. 4, the outer wall 2b of the locking member 2 is projected in the horizontal direction, the mounting rod 5 is formed at the tip thereof, and the mounting rod mounting portion 10 is opened outward. The outer wall 2b of the member 2 is vertically raised, and the mounting rod 5 is mounted on a mounting rod mounting portion 10 having a downward opening. FIG. The rod 5 is mounted on the mounting rod mounting portion 10 having an inward opening.

Further, FIG. 7 shows that the engaging member 2 is provided with a groove, and the attachment rod of the connecting tool is attached to the groove.
A lower end portion of the outer wall 2b is bent to form an upward mounting groove 15. Then, a downward locking wall 9a is formed on a side portion of the base 9 of the connecting tool, a mounting rod 16 is continuously provided on the locking wall 9a, and the mounting rod 16 is rotatably mounted in the mounting groove 15. I am doing it. A locking projection 6 is formed on the outer side of the edge of the inner wall 2c of the locking member 2, and a groove 12c formed inside the upper portion of the closing stopper 12 is locked to the locking projection 6.

In each of the above-mentioned embodiments, the guide groove is provided obliquely, but since the position of the rotary shaft of the frame material is low, there is little contact between the end portions of the frame material, and the guide groove can be practically used without providing the guide groove obliquely. .
Further, the guide groove may be formed in a closed shape so as to more reliably prevent the sliding prevention stopper from coming off. Further, a guide groove may be formed in the connecting tool, and a protrusion serving as a slide prevention stopper may be provided on the inner wall of the locking member to lock the both. If the locking member 2 is made of synthetic resin and its outer wall 2b is made flexible, the frame member 1 can rotate smoothly.

[0015]

According to the present invention, since the locking member is attached to the lower portion of the frame member and the connecting member and the frame member are rotatably connected via the locking member, the connecting member is connected to the frame member itself. It is not necessary to form a groove for mounting with. Therefore, the frame member can be rotated even with a wooden frame member for which the conventional structure for rotating the frame member cannot be adopted. Further, since the position of the rotating shaft during rotation can be positioned as low as possible, the amount of movement of the lower portion of the frame member during rotation is small, and the contact between the end portions of the adjacent frame members is substantially prevented. It can be resolved. Further, since the inner wall of the locking member that locks with the closing stopper is not involved in the connection with the frame member, the locking force of the closing stopper can be freely set by adjusting the state of the inner wall.
Further, this adjustment does not affect the connection state between the frame member and the connecting tool. Further, by locking the slide prevention stopper and the guide groove, there is no risk that the frame member will come off the connector or be displaced during the opening / closing operation of the frame member. Moreover, if the guide groove is formed so as to be directed upward and away from the end of the frame, the end of the frame is twisted so as to move away from the end of the adjacent frame when the frame is rotated outward. Therefore, the end portion of the frame member does not collide with the adjacent frame member, and the frame member can be smoothly rotated.
