DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame having a frame fixed to a peripheral portion of a board, a frame used for the frame, and a jig for forming a groove in the board.

[0002]

2. Description of the Related Art It is known that a simple frame for decorating a photograph, a picture, a poster, a lithograph, etc. is combined with an aluminum material. This is obtained by cutting a mold material having a constant cross section formed by aluminum extrusion into a predetermined length and screwing or riveting a dedicated metal fitting at a corner.

[0003] In addition, at least one side of the frame is made detachable with a screw, and a board or a transparent acrylic plate (or a glass plate) is mounted with the shape material removed. Then, a holding member for pressing the board or the acrylic plate from the back side is mounted between the die and the material, and the board or the acrylic plate is fixed to the material. The pressing member used here is usually a bent leaf spring, and a large number of pressing members are manually attached and detached.

[0004]

2. Description of the Related Art In such a conventional frame, a dedicated metal fitting is fixed with a screw or a rivet to assemble a shape member, so that the number of parts is increased, and assembly and disassembly are troublesome. When a board or an acrylic plate is incorporated, or a picture or a picture is exchanged, a holding member such as a leaf spring for fixing these to a mold must also be detached. Therefore, the work of exchanging photographs and pictures was more troublesome.

[0005] Further, it is conceivable to put a guide text or a guide map of the inside of a store or the like in such a frame and use it simply for guidance. However, conventional aluminum molds are relatively heavy and inconvenient to carry, and there is also a problem that it is difficult to handle because exchange of guide text (FIG.) Is troublesome.

That is, the frame member 10 is formed by integrating an edge portion 14 facing the outer periphery of the board 12 and a front portion 16 and a back portion 18 connected to the edge portion 14.

At the tip of the back portion 18, a ridge 20 projecting toward the front portion 16 is formed. The ridge 20 has a sharp cross section formed by a plane whose tip is substantially perpendicular to the ridge 20, and the acute angle is inclined toward the edge 14 side. That is, the angle 22 between the surface 20A (FIG. 4) of the ridge 20 facing the edge 14 and the back 22 is substantially 90 °.
Or less than that. The front part 1 of the back part 18

The front portion 16 and the back portion 18 have their tip sides closer to each other than the edge portion 14 side, and have an appropriate elasticity in the direction of approaching each other by using the inherent elasticity of the hard vinyl chloride resin itself as a material. Have.

As the board 12, a honeycomb board made of hard paper, which is slightly thinner than the width of the edge portion 14 of the frame member 10, is suitable.
This honeycomb board 12 is obtained by bonding a front plate 12b and a back plate 12c to both surfaces of a core plate 12a having a large number of substantially hexagonal small holes in the thickness direction, has appropriate rigidity, and is sufficiently light. .

The back plate 12c of the board 12 has a frame 1
A streak groove 24 is formed to be engaged with the ridge 20 provided on the back portion 18 of the zero. The streak portion 24 can be easily formed by moving a jig, which will be described later, at a position separated from the peripheral edge of the board 12 by a predetermined distance along the peripheral edge of the board 12. The groove 24 has a V-shaped cross section formed by a plane substantially perpendicular to the groove 24 and has an acute angle, and the acute angle is inclined toward the outer peripheral edge of the board. That is, this muscle groove 24
The angle θ2 between the surface 24a (FIG. 3) on the outer peripheral side of the board and the back plate 12c of the board 12 forms approximately 90 °.

The frame member 10 has a length corresponding to the length of each side of the board 12 and both ends are preliminarily cut at 45 °. The frame member 10 engages each side of the board 12 between the front part 16 and the back part 18 while pushing and opening the space between the front part 16 and the back part 18. By pushing the frame member 10 into each side of the board 12, the frame member 10 can be engaged with the peripheral edge of the board 12. At this time, the back portion 18 of the frame material 10
Is engaged with the groove 24 of the board 12.

As a result, the tip of the front portion 16 is
The board 12 is pressed at the contact position A (FIG. 2) with the front plate 12b. The back portion 18 is located at the position B of the ridge 20 and the back portion 18.
The board 12 is pressed at two locations of the base side contact position C.
Here, the contact position C of the back portion 18 is a position where the surface 22 of the back portion 18 and the board 12 are in contact, and is sufficiently close to the root side of the back portion 18. For this reason, the contact position A of the front plate 12b is
2c is located between the contact positions B and C.

As described above, the frame member 10 presses the front side of the peripheral portion of the board 12 at one position A, and presses the back side at two positions B and C on both sides of the position A with three positions. Since the periphery of the board 12 is sandwiched between the front and back at the positions A, B, and C, the frame member 10 is stably held on the board 12. Further, the ridge 20 of the frame member 10 is pressed in a direction of engaging with the groove 24 of the board 12, and the tip of the ridge 20 has an acute angle in cross section and the surface 20 a on the edge 14 side is sandwiched between the ridge 20 and the back 22. The angle θ1 is approximately 90 ° or less, and the groove 24 has a cross section V
Since the sandwiching angle θ2 between the surface 24a on the board peripheral edge side and the back surface of the board is set to approximately 90 °, the projection 20 is
4, the surface 20a of the ridge 20 and the surface 24 of the groove 24
The frame member 10 is firmly held on the board 12 by abutment with the a, and the falling off is surely prevented.

The four frame members 10 are attached to the four sides of the board 12 in this manner.
May be attached to the frame member 10. This hanging tool 30 is, for example, one in which ball chains 34 are connected to both ends of a wire 32, and is attached to a frame material 10a (FIG. 1) serving as an upper side of a frame.
And a pair of left and right long holes 36 as shown in FIG. 1 are formed, and the ball chain 34 of the hanging member 30 is locked here. Here, the ball chain 34 is formed by connecting a large number of small balls in a daisy chain to form a chain. The long hole 36 has a small hole 36 through which the ball of the ball chain 34 passes.
a, and the small ball of the ball chain 34 is
The ball can be locked in the long hole 36 by moving the ball in the long hole 36 after being put in the long hole 36.

In FIGS. 6 and 7, reference numeral 40 denotes a jig for forming the groove 24, which has a slide body 42 and a rotary blade 44. The slide body 42 includes a lower bent portion 46 that engages with the outer peripheral edge of the board 12, a horizontal portion 48 that contacts the back surface of the board 12, and an upright portion 50 that rises from the horizontal portion 48 in parallel with the lower bent portion 46. With The rotary blade 44 is a horizontal part 4
The support shaft 50 is rotatably held by the upright portion 50 by a support shaft 52 substantially parallel to the support shaft 8.

This rotation 44 has a substantially trapezoidal sectional shape as shown in FIG. 7 on a plane including the support shaft 52, and its long bottom side is located on the outer peripheral side of the board, that is, on the lower bent portion 46 side. The rotary blade 44 can form the groove 24 by moving the lower edge bent portion 46 along the peripheral edge of the board 12 in contact with the outer peripheral edge of the board 12. The rotary blade 44 is positioned on the slide body 42 such that the groove 24 has a position and a depth at which the groove 24 is engaged with the ridge 20 of the frame member 10.

In this embodiment, the contact position A on the front portion 16 side of the frame member 10 is located between the contact positions B and C on the back portion 18 side, so that the stability of the frame member 10 is very good. Even if the contact position A is slightly shifted between the contact positions B and C, the effect of the present invention can be sufficiently obtained. For example, if the contact position A of the front portion 16 is displaced toward the ridge 20, the pressing force of the ridge 20 against the groove 24 increases, and the engaging force between the ridge 20 and the groove 24 increases. Become. For this reason, the holding force of the frame member 10 increases, and the frame member 10 is harder to fall off.

If a honeycomb board made of hard paper is used as the board 12, it is possible to easily form the groove 24 in the back plate 12c, obtain sufficient strength, and be suitable for weight reduction. However, it is a matter of course that the board 12 may be made of another material, for example, a lightweight resin plate such as a styrene foam plate, or a plate using a combination of paper and resin. The top plate 1 of the board 12
On 2b, you can attach objects to be exhibited, such as photos and posters,
The board 12 can be cut into substantially the same size, and its periphery can be overlapped with the board 12 and sandwiched between the frame members 10.

Also, a transparent acrylic plate (or glass plate) is superimposed on the front plate 12b of the board 12 so as to be sandwiched between the frame members 10, and a display such as a photograph is displayed between the board 12 and the acrylic plate. An object may be interposed. The frame member 10 can be used for a board having an arbitrary size by cutting an extruded long one into an appropriate length.

[0025]

As described above, according to the first aspect of the present invention, a groove is formed on the back surface of the board at a position separated from the outer periphery of the board by a predetermined distance in parallel with the outer periphery of the board, and the frame has a substantially U-shaped cross section. A ridge is formed on the back of the material to engage with the groove, and the contact position (A) between the front portion of the frame material and the board surface is closer to the outer periphery of the board than the ridge. The frame material is elastically held between the front and back portions.

Therefore, the construction is very simple, the number of parts is reduced, and the assembly and disassembly are simple. Further, the contact position (A) on the front surface is located between the contact position (B) of the ridge that supports the back surface of the board and the contact position (C) on the base side of the back portion. Therefore, the frame material is stably held on the board. Since the ridges provided on the back of the frame material are constantly pressed in the direction of engaging with the groove, the frame material is firmly held on the peripheral edge of the board and is prevented from falling off.

Since the frame material itself has elasticity, if the board is thinner than the width of the edge connecting the front portion and the back portion, there is no problem even if the thickness of the board slightly changes. The degree of freedom with respect to the size is increased. Furthermore, since the frame material is made of a hard synthetic resin, it is suitable for weight reduction, convenient for carrying, and easy to handle. For this reason, it becomes suitable for use in providing guidance in a store or the like with guidance text (FIG.) Or the like.

Since the frame material used here has a constant cross-sectional shape, it can be manufactured at low cost by extrusion, and the extruded product can be cut into a predetermined length for use, so that the production is easy. Yes, it can correspond to an arbitrary board size (claim 2). If the ridge provided on the frame material has a sharp end at the tip and the angle (θ1) between the edge-side surface and the back is approximately 90 ° or less, the ridge is firmly fixed. The frame material is firmly fixed to the board because it engages with the groove (claim 3).

Here, the groove has a similar shape, that is, a V-shape having an acute cross-section, and if the angle (θ2) between the surface on the outer peripheral edge side of the board and the back surface of the board is approximately 90 °, the groove is convex. The engagement with the strip is further strengthened (claim 4).
The board is preferably a honeycomb board made of hard paper. In this case, it is easy to process the groove and suitable for weight reduction, and a sufficient strength is obtained (claim 5). According to the invention of claim 6, a frame material used for the frame is obtained, and according to the invention of claim 7, a jig for processing a groove is obtained.
