1. Field of the Invention
The present invention relates to an ornament holder, such as a covered button, that is used while holding an ornament.
2. Description of Related Art
Conventionally, in the fields of handicrafts and the like, a covered button that is used while holding an ornament such as a decorative fabric is known (see JP-U-A-S62-64311, for example). The covered button disclosed in JP-U-A-S62-64311 includes a frame main body having a shaft portion at its center and a presser plate having at its center a hole into which this shaft portion is to be fitted. The shaft portion is provided with a locking step portion. Moreover, the frame main body has a rising wall at its peripheral edge, and a plurality of locking protrusions are provided on an inner side surface of the rising wall.
To use the covered button disclosed in JP-U-A-S62-64311, for example, a surface of the frame main body is covered with a decorative fabric, and a peripheral edge portion of the decorative fabric is folded over the inner side surface of the rising wall. Then, the presser plate is placed with its lower peripheral edge facing downward, the hole is fitted to the shaft portion of the frame main body, and the presser plate is forcibly pushed downward into place. In this manner, the presser plate is attached to the frame main body. In a state in which the presser plate is attached, an annular wall surrounding the hole of the presser plate engages with the locking step portion of the shaft portion, thereby restricting the upward movement of the presser plate, and the lower peripheral edge of the presser plate abuts against the locking protrusions via the peripheral edge portion of the decorative fabric, thereby restricting the upward movement of the presser plate. A hole to be used to sew the button on a garment or the like is provided at a leading end of the shaft portion.
With the above-described conventional configuration, the presser plate can be appropriately attached to the frame main body. On the other hand, the above-described conventional engagement structure for the frame main body and the presser plate is not suited for applications other than the use as a covered button.
The present invention was conceived in light of the above-described circumstances, and a main object thereof is to provide an ornament holder having an improved engagement structure for a frame main body and a presser plate and thus being suitable for broadening the applications.
According to a first aspect of the invention, there is provided an ornament holder provided with: a frame body including a first plate-like portion and a plurality of locking shafts extending from the first plate-like portion in a first direction; and a presser plate formed with a hole into which the plurality of locking shafts are inserted. The presser plate is attachable to the frame body. The locking shafts include first locking portions each protruding in a direction crossing the first direction. The presser plate includes first locked portions disposed adjacent to the hole and configured to engage with the first locking portions of the locking shafts. The locking shafts are elastically deformable so as to approach each other when being inserted into the hole.
In an embodiment, the plurality of locking shafts include two locking shafts spaced apart from each other in a second direction perpendicular to the first direction.
In an embodiment, each of the locking shafts is provided with a protrusion protruding in the first direction, the presser plate is provided with a pair of upright walls spaced apart from each other with the hole intervening therebetween, and each of the upright walls is provided with a second locking portion extending toward the other of the upright walls.
In an embodiment, the protrusion of each of the locking shafts is provided with a third locking portion extending away from a central axis common to the locking shafts.
In an embodiment, the first locking portions and the first locked portions are provided with rounded abutment regions, respectively. The abutment regions of the first locking portions are brought into contact with the abutment regions of the first locked portions when the locking shafts are inserted into the hole.
In an embodiment, the presser plate includes a second plate-like portion formed with the hole and a pair of movable arms configured to move relative to the secondplate- like portion. The movable arms are spaced apart from each other with the hole intervening therebetween, and each of the movable arms is defined by a first slit and a second slit both formed in the second plate-like portion, where the first slit is closer to the hole than is the second slit.
In an embodiment, each of the movable arms has a arched shape including a first end, a second end and an intermediate portion connecting the first end and the second end, where the intermediate portion is greater in thickness than each of the first end and the second end.
According to a second aspect of the invention, there is provided an ornament holder provided with: a frame body including a first plate-like portion and a locking shaft extending from the first plate-like portion in a first direction; a presser plate attachable to the frame body and formed with a hole into which the the locking shaft is inserted; and a disengagement preventing implement for holding the locking shaft in the hole. The presser plate includes a second plate-like portion formed with the hole and a pair of movable arms configured to move relative to the second plate-like portion. The movable arms are spaced apart from each other with the hole intervening therebetween. Each of the movable arms has an arched shape and is defined by a first slit and a second slit formed in the second plate-like portion, where the first slit is closer to the hole than is the second slit.
Other features and advantages of the present invention will become apparent from the detailed description given below with reference to the accompanying drawings.
Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.
The frame main body 1 has a plate-like portion 10 that has a substantially circular shape when viewed from above, and a plurality of (two, in the present embodiment) locking shafts 11, 12 extending from this plate-like portion 10 in a direction “z” along a central axis Ox of the plate-like portion 10.
As shown in
The frame main body 1 may be obtained by, for example, integrally forming a synthetic resin, such as polypropylene, having a predetermined strength.
The presser plate 2 includes a substantially disk-shaped main plate portion 20, and the hole 20a is formed at the center of the main plate portion 20, passing therethrough in a thickness direction. The hole 20a has a hexagonal shape, and during attachment of the presser plate 2 to the frame main body 1, the pair of locking shafts 11, 12 fit into this hole 20a. The thickness of the main plate portion 20 may be, for example, about 1 to 1.5 mm.
The main plate portion 20 (presser plate 2) is provided with two movable arms 21. The movable arms 21 are spaced apart from each other in the direction “x” and provided on opposite sides of the hole 20a so as to be paired with each other. Each movable arm 21 is constituted by a portion that is located between corresponding slits 22 and 23, the slits passing through the main plate portion 20 in the thickness direction. The slits 22 are provided on a side close to the hole 20a with respect to the corresponding movable arms 21, while the slits 23 are provided on a side away from the hole 20a with respect to the corresponding movable arms 21. Each of the movable arms 21 has a substantially uniform width along its length when viewed from above, and has two thin-walled connection portions or ends 211 connected to the main plate portion 20 and a curved main portion that is connected to the respective ends 211 and greater in thickness than each connection portion 211. In the illustrated example, the curved main portion (and hence the entire arm 21) is arched or U-shaped. The thickness of the thin-walled connection portions 211 may be about 0.3 mm. Each movable arm 21 can be rotated about an axis extending through the two connection portions 211 so as to be raised in the direction “z” for taking an upright position. As can be understood with reference to
As can be seen in
The presser plate 2 may be obtained by, for example, integrally forming a synthetic resin, such as polypropylene, having a predetermined strength.
When the pair of locking shafts 11, 12 are fitted into the hole 20a of the main plate portion 20 (presser plate 2), an inner peripheral edge portion of the main plate portion 20 that surrounds the hole 20a engages with the locking portions 111, 121 of the locking shafts 11, 12, and thus disengagement of the main plate portion 20 (presser plate 2) from the locking shafts 11, 12 is restricted.
More specifically, those regions, of the inner circumferential edge portion of the main plate portion 20 that surrounds the hole 20a, that correspond to the respective locking portions 111, 121 of the locking shafts 11, 12 constitute locked portions 201, 202 (see
During attachment of the presser plate 2 to the frame main body 1, when the main plate portion 20 (presser plate 2) is pushed down while fitting the locking shafts 11, 12 into the hole 20a, as shown in
Next, several manners in which the ornament holder A having the above-described configuration is used and the effects thereof will be described with reference to
The ornament holder A of the present embodiment can be used for a plurality of applications, and may be used as, for example, a covered button, a brooch, and a hair ornament.
A case where the ornament holder A is used as a covered button will be described. As shown in
Next, the presser plate 2 is attached to the frame main body 1. The presser plate 2 is attached by pushing down the main plate portion 20 (presser plate 2) while fitting the locking shafts 11, 12 of the frame main body 1 into the hole 20a of the presser plate 2. As shown in
Next, as shown in
Next, a case where the ornament holder A is used as a brooch will be described. In the case where the ornament holder A is used as a brooch, the ornament holder A is fitted with a metal fitting for a brooch. First, as shown in
Next, the presser plate 2 on which the metal, fitting 3 is placed is attached to the frame main body 1 fitted with the decorative fabric C. Here, the distance between the centers of the attachment holes 311 of the metal fitting 3 is slightly smaller than the distance between the centers of the protrusions 112, 122 of the presser plate 2 in the natural state. Moreover, the size of each attachment hole 311 is slightly larger than the size of a cross section of the corresponding protrusion 112 (122) that is perpendicular to a height direction thereof.
During attachment of the presser plate 2 to the frame main body 1, the presser plate 2 is pushed down together with the metal fitting 3 while the locking shafts 11, 12 of the frame main body 1 are fitted into the hole 20a of the presser plate 2. Then, as the locking shafts 11, 12 approach the central axis Ox, the distance between the centers of the protrusions 112, 122 at the leading ends of the locking shafts 11, 12 also slightly decreases, and the protrusions 112, 122 are thus fitted in the pair of attachment holes 311. When the presser plate 2 is further pressed down, the locked portions 201, 202 pass by the respective locking portions 111, 121, and thus the locking shafts 11, 12 return to the natural state due to their elastic restoring force (see
Therefore, according to the present embodiment, the metal fitting 3 can be fitted to the ornament holder A by a simple operation of pushing down the metal fitting 3 together with the presser plate 2. Moreover, the thus fitted metal fitting 3 is firmly fixed to the ornament holder A by the cooperation of the locking portions 113, 123 and the locking portions 241, and thus a robust brooch can be provided.
Next, a case where the ornament holder A is used as a hair ornament will be described. In the case where the ornament holder A is used as a hair ornament, the same procedure as that in the case where the ornament holder A is used as a covered button, which has been described above with reference to
As described above, according to the ornament holder A of the present embodiment, since the engagement structure for the frame main body 1 and the presser plate 2, or the like is designed with some contrivance, the ornament holder A can be used for a plurality of applications.
While a specific embodiment of the present invention has been described above, the present invention is not limited to the foregoing embodiment, and various modifications are possible without departing from the gist of the invention. It should be understood that specific shapes and materials of the ornament holder according to the present invention also are not limited to those described in the foregoing embodiment.
In the foregoing embodiment, a case where the frame main body 1 has a circular shape has been described. However, the shape of the frame main body may also be other shapes such as, for example, an elliptical shape.
Examples of the ornament to be held by the ornament holder according to the present invention include various embroidery works such as wool embroidery and beads embroidery and decorative fabrics such as patchwork, as well as handicraft works such as knits and beaded fabrics, and furthermore, soft articles having relatively small thicknesses.
