JP 2016-33282 A

By the way, as picture frames applied to fittings, many frames made of metal such as aluminum alloy or resin are used. These metals and resins are materials with relatively high elasticity. Therefore, if the frame is bent along the break-off groove, the edge on the base end side, which should be left as the frame, may be deformed. These problems may be improved by increasing the thickness of the frame. However, the picture frame is generally made of an extruded shape, and considering formability, it is difficult to secure a large depth of the breaking groove. As a result, when the plate thickness increases, workability may be affected, for example, a large operating force is required for breaking off the plate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a picture frame capable of improving the appearance quality after breaking off without impairing workability.

In order to achieve the above object, a picture frame according to the present invention includes a plate-like substrate portion supported via a mounting portion provided on a base end edge portion, and the substrate portion has a virtual cutting plane. a frame for break-off extending along the substrate portion and opening to the surface of the substrate portion, wherein the deepest portion of the groove is located on the imaginary cutting plane and An opening is formed on the surface of the substrate portion so that the tip side is larger than the end side, and the bottom portion of the groove is formed symmetrically with respect to the imaginary cutting plane.
Further, the picture frame according to the present invention includes a plate-like substrate portion supported via a mounting portion provided at the edge on the base end side, and the substrate portion extends along an imaginary cutting plane. and a frame having a break-off groove that opens to the surface of the substrate portion, wherein the deepest portion of the groove is located on the imaginary cutting plane and is oriented with respect to the base end side It is characterized in that an opening is formed on the surface of the substrate portion so that the tip side becomes larger, and the bottom portion of the groove and the opening edge portion of the groove are each formed of curved surfaces.

According to the present invention, the positions of the openings are asymmetric with respect to the virtual cutting plane, and the rigidity on the distal end side is smaller than that on the proximal end side. This eliminates the need for a large operating force when breaking off, and eliminates the possibility that the base end side will be affected by deformation.

The cover substrate portion 32 of the indoor picture frame 30 is in a state in which the extended edge portions are in contact with the interior facing surfaces of the new upper frame 10a and the new vertical frame 10c. The projecting length of the mounting base plate portion 31a in the cover mounting portion 31 toward the inner circumference and the extension length of the cover base plate portion 32 along the projection direction are cut along the break-off grooves 31b and 32a provided respectively. It has been adjusted accordingly.

The outdoor picture frame 40 is for hiding the outer peripheral portions of the newly installed upper frame 10a and the newly installed vertical frame 10c from the facing surfaces facing the outside of the room. In this embodiment, an outdoor picture frame 40 having a facing side member 41 and a projection side member 42 is provided for each of the newly installed upper frame 10a and the newly installed vertical frame 10c.

The facing side member 41 is arranged so as to cover the surface from the facing surface of the newly installed upper frame 10a and the newly installed vertical frame 10c facing the outside to the exterior material F of the building beyond the existing frame 2. . More specifically, the facing side member 41 provided on the newly installed upper frame 10a has a frame mounting portion (mounting portion) 41a attached to the facing surface of the newly installed upper frame 10a, and is positioned on the outer peripheral side of the frame mounting portion 41a. After extending from the edge toward the outer peripheral side, the projection plate portion 41b that is bent to the outdoor side and extends in the projection direction, and the extension edge portion of the projection plate portion 41b that extends toward the outer peripheral side It is formed integrally with the base board portion (board portion) 41c.

A plurality of break-off grooves 41d extending along the longitudinal direction are provided on the outer peripheral portion of the inner surface of each of the base plate portions 41c.

The prospective side member 42 is arranged so as to cover the gap between the edge portion arranged on the outer peripheral side of the base plate portion 41c and the exterior material F of the building. In the present embodiment, a projected side member 42 having a flat plate-shaped projected substrate portion (substrate portion) 42a that is common to the newly installed upper frame 10a and the newly installed vertical frame 10c is applied. A plurality of break-off grooves 42b extending along the longitudinal direction are provided on the inner peripheral surface of the prospective substrate portion 42a.

As shown in FIGS. 1 and 2, between the edge portion of the attachment side member 41 located on the outer peripheral side of the attachment substrate portion 41c and the edge portion of the attachment side member 42 located on the outdoor side of the attachment substrate portion 42a. is provided with an engaging mounting portion (mounting portion) 43 . The engagement attachment portion 43 detachably connects the end side member 41 and the prospect side member 42, and comprises a first engagement element pair 43A and a second engagement element pair 43B. There is.

The first engaging element pair 43A is composed of a projection side hook portion 44 provided on the projection substrate portion 42a and a viewing side hook portion 45 provided on the viewing side member 41. As shown in FIG. When the prospective side hook portion 44 and the access side hook portion 45 are engaged with each other, the prospective side member 42 is separated from the prospective side member 42 centering on the end edge portion located on the exterior side of the prospective side member 42 (the tip edge of the prospective side hook portion 44). 42 can be supported so as to be rotatable with respect to the viewing side member 41 . Further, when the fitting side hook portion 45 and the fitting side hook portion 44 are engaged with each other, the fitting side member 42 moves toward the outer peripheral side and toward the outside of the room with respect to the fitting side member 41 (in the direction toward the fitting side member 41). movement) is restricted.

When the second engaging element pair 43B is rotated toward the inner peripheral side in the state where the first engaging element pair 43A is engaged with each other are engaged with each other. In this embodiment, it has an engaging piece 47 protruding from the inner surface positioned on the inner peripheral side of the projection board portion 42a, and an engagement receiving portion 48 protruding from the inner surface facing the interior of the fitting board portion 41c. A second pair of engaging elements 43B is formed by combining the two.

In the outdoor picture frame 40 configured as described above, by screwing screws 50 onto the facing surfaces of the new upper frame 10a and the new vertical frame 10c facing the outside through the frame mounting portions 41a, the facing base plate portion 41c is formed on the outer circumference. A facing side member 41 is attached so as to cover the sides. After screwing the screw 50, the cap 51 is attached to the frame attachment portion 41a.

After that, the fitting side member 42 is connected to the outer peripheral side edge of the fitting base plate portion 41 c of the fitting side member 41 via the engaging attachment portion 43 . That is, when the end edge portion of the projection side member 42 located on the interior side is rotated toward the inner peripheral side in a state where the first engagement element pair 43A is engaged, the engagement piece provided on the projection side member 42 is rotated. 47 is engaged with the engagement receiving portion 48, and the leading edge portion of the engagement receiving portion 48 is in contact with the surface of the engaging piece 47 located on the outside of the vehicle. As a result, the prospective side member 42 is maintained in a state of being connected to the prospective side member 41, and the prospective side member 42 covers the gap between the prospective side member 41 and the exterior material F of the building. Become. The extension length of the prospective side member 42 is appropriately adjusted in advance by cutting along the break-off groove 42b.

Here, when the mounting substrate portion 31a and the cover substrate portion 32 of the indoor picture frame 30 are cut along the break-off grooves 31b and 32a, and the projection side member 42 of the outdoor picture frame 40 is cut along the break-off groove 42b. In this case, as shown in FIG. 3, the tip side of the breaking grooves 31b, 32a, and 42b to be cut is held by a tool T such as pliers, and the breaking grooves 31b, 32a, and 42b are expanded. An operation force is applied to the frames 30 and 40 so as to do so. The same is true when cutting the viewing side member 41 along the break-off groove 41d. If the thickness of the frames 30, 40 is small, the base ends 30A, 40A of the frames 30, 40 may be deformed when cut along the break-off grooves 31b, 32a, 42b, 41d. Base end sides 30A and 40A of the frames 30 and 40 are portions that remain as the frames 30 and 40 in the building. Specifically, the mounting substrate portion 31a and the cover substrate portion 32 of the indoor picture frame 30 are on the side where the cover mounting portion 31 is provided with respect to the break-off grooves 31b and 32a. The portion 42a is the side on which the engaging attachment portion 43 is provided with respect to the break-off groove 42b. The base end side 40A of the attachment base plate portion 41c of the attachment side member 41 is the side on which the frame mounting portion 41a is provided with respect to the break-off groove 41d. Therefore, it cannot be said that it is necessarily preferable that the portions of the base end sides 30A and 40A are deformed in consideration of appearance quality. On the other hand, when the plate thickness of the frame 30, 40 is increased, workability may be affected, for example, a large operating force is required for breaking off the frame.

Therefore, in the frames 30 and 40 of the embodiment, as shown in FIG. 4, the deepest portion a is positioned on the virtual cutting plane CP, and the surfaces of the substrate portions 31a, 32, 42a, and 41c are located on the base end side. Break-off grooves 31b, 32a, 42b, and 41d are formed so that tip sides 30B and 40B are wide open with respect to 30A and 40A. As is clear from the drawings, the bottoms b of the break-off grooves 31b, 32a, 42b, and 41d are formed by curved surfaces c that are bilaterally symmetrical with respect to the imaginary cutting plane CP. Curved surfaces d and e are provided at the opening edges of the break-off grooves 31b, 32a, 42b and 41d on the surfaces of the substrate portions 31a, 32, 42a and 41c. The curved surface d of the opening edge located on the base end side 30A, 40A of the break-off grooves 31b, 32a, 42b, 41d is configured so that the radius of curvature r1 is smaller than the radius of curvature r3 of the curved surface c forming the bottom b. I have Furthermore, in the illustrated example, the curvature radius r2 of the curved surface e of the opening edge located on the tip side 30B, 40B of the break-off grooves 31b, 32a, 42b, 41d is larger than the curvature radius r3 of the curved surface c forming the bottom b. It is designed to be large.

In the frames 30 and 40 having the breaking grooves 31b, 32a, 42b, and 41d having the cross-sectional shapes as described above, the breaking grooves 31b, 32a, 42b, and 41d are asymmetric with respect to the virtual cutting plane CP. , the rigidity of the distal end sides 30B and 40B is smaller than that of the proximal end sides 30A and 40A. As a result, as shown in FIG. 5, a large operating force is not required when breaking off the frames 30, 40 at the desired cutting plane, and there is no possibility that the base end sides 30A, 40A will be affected by deformation. can be cut. In particular, in the frames 30 and 40 of the embodiment, the base end sides 30A and 40A are deformed because the rigidity of the base end sides 30A and 40A is higher than that of the bottom b of the break-off grooves 31b, 32a, 42b and 41d. The situation can be prevented more reliably. Furthermore, since a desired width can be secured for the bottom portions b of the break-off grooves 31b, 32a, 42b, and 41d, for example, a cutter can be inserted to cut the frames 30 and 40, which facilitates break-off. Work can be done more easily. In addition, since the break-off grooves 31b, 32a, 42b, and 41d are configured without corners, it is advantageous in terms of moldability during extrusion molding, and there is no fear of causing problems in manufacturing.

In the above-described embodiment, the bottoms b of the break-off grooves 31b, 32a, 42b, and 41d are symmetrically formed with respect to the imaginary cutting plane CP. For example, the width of the base end sides 30A and 40A of the bottom part b may be smaller than the width of the tip part side, and the bottom part b may be a space only on the tip part side. It is also possible to configure The bottoms b of the break-off grooves 31b, 32a, 42b, and 41d are formed by curved surfaces c, and the opening edges of the break-off grooves 31b, 32a, 42b, and 41d are formed by curved surfaces d and e. The invention is not limited to this, and the break-off groove may be formed so as to form a V-shaped bottom b, or the break-off groove may be formed so that the corners of the ridges are formed between the surface of the substrate portion. may be formed.

Furthermore, in the above-described embodiment, the frames 30 and 40 provided on the frame 10 of the remodeling door are illustrated, but they are not necessarily doors, and can be applied to other fittings. . The fittings in this case need not be for renovation. Furthermore, although the frames 30 and 40 formed of an aluminum alloy are illustrated, the frames may be formed of a metal or resin other than an aluminum alloy.

As described above, the picture frame according to the present invention includes a plate-like substrate portion supported via the mounting portion provided on the edge portion on the base end side, and the substrate portion is provided along a virtual cut plane. A picture frame provided with a break-off groove that extends and opens to the surface of the substrate portion, wherein the deepest portion of the groove is positioned on the imaginary cutting plane and extends toward the base end side. It is characterized in that the opening is formed on the surface of the substrate part so that the tip side thereof becomes larger than the tip side.

According to this invention, the positions of the openings are asymmetric with respect to the virtual cutting plane, and the rigidity on the distal end side is smaller than that on the proximal end side. This eliminates the need for a large operating force when breaking off, and eliminates the possibility that the base end side will be affected by deformation.

Further, according to the present invention, in the picture frame described above, the bottom of the groove is formed symmetrically with respect to the virtual cut plane.

According to this invention, since a desired width can be secured inside the groove, for example, a cutter can be inserted to add a cut, so that the work at the time of breaking off can be performed more easily. Become.

Further, according to the present invention, in the picture frame described above, a bottom portion of the groove and an opening edge portion of the groove are each formed by a curved surface.

According to the present invention, it is possible to configure the break-off grooves without providing corners, which is advantageous in terms of moldability during extrusion molding.

Further, according to the present invention, in the picture frame described above, the curved surface provided at the opening edge on the base end side of the groove has a smaller radius of curvature than the curved surface provided at the bottom of the groove. do.

According to this invention, since the rigidity of the base end side is higher than that of the bottom portion of the groove, it is possible to more reliably prevent the deformation of the base end side.
