Description

  The present invention relates to a clip such as a laundry clip or a document clip. In particular, the present invention relates to a clip made by molding a plastic material.

  Clips such as a laundry clip and a document clip are well known. It is also well known to manufacture the clip members constituting these clips by molding a plastic material. A clip having a known structure combines a pair of clip members so as to be pivotable with respect to a pivot shaft, and a metal coil spring is arranged around the pivot shaft to give an elastic biasing force to the clip members. The clip engaging edges of the clip members are engaged with each other. This pinching engagement of the edge can be released by pinching the pair of clip members with fingers at the end far from the pinching engagement edge.

  The structure of such a clip is well known, not to mention the literature, and can be seen around the body.

  An object of the present invention is to provide a novel clip that does not require a metal coil spring like a conventional clip and can be configured only by a clip member manufactured by integral molding of a plastic material.

  According to the present invention, a pair of clip members each having a pinching engagement edge is combined so as to be rotatable about an axis in a relationship in which the pinching engagement edges face each other, and the pair of clip members are used for the pinching engagement. The edges are elastically biased in the direction in which they are engaged with each other, and the clip engaging member is rotated against the elastic bias to open the clip engaging edge from the engagement position. In the clip, the clip member is configured as an integrally molded product of a plastic material, and each clip member is provided with a main body portion having a pinching engagement edge portion and an engagement release operation portion, and at least one of the clip members is provided. One end is integrally coupled to the main body portion, and the elastic piece is extended so as to extend obliquely in a direction opposite to the edge for engagement with respect to the pivot shaft and away from the main body portion of the clip member. The body Minutes and formed integrally on the other clip member to form an engagement portion for receiving the other end of the elastic piece. Then, the other end of the one clip member is engaged with the engagement portion of the other clip member, and an elastic biasing force is applied between the pair of clip members.

  One end of the other clip member is integrally coupled to the main body portion, and is inclined in the direction opposite to the edge of the pinching engagement with respect to the rotation shaft and away from the main body portion of the clip member. An extending elastic piece can be formed integrally with the body portion. In this case, the engaging portion of the other clip member can be constituted by the other end of the elastic piece of the other clip member. Further, in the clip according to the present invention, a magnet can be attached to one of the pair of clip members so that it can be magnetically attached to a magnetic object.

  Since the clip according to the present invention is configured as described above, it does not require a metal coil spring as in the conventional clip, and the clip can be configured only by a clip member integrally formed of a plastic material. . Therefore, the number of parts of the clip is reduced, and the number of assembling steps is greatly reduced.

  1 and 2 are a side view and a cross-sectional view showing a clip 1 in a closed state according to an embodiment of the present invention. The clip 1 includes a first clip member 2 and a second clip member 3. As can be seen from the plan view of FIG. 3, the clip members 2, 3 have flat portions 2 a, 3 a having a substantially quadrangular planar shape, and the engaging edges 2 b, 3 b are sandwiched on one side of the flat portions 2 a, 3 a. It is formed. The first clip member 2 is formed with an end wall 2c extending at a right angle from the flat portion 2a on the opposite side of the pinch engagement edge 2b, and between the end wall 2c and the pinch engagement edge 2b. A pair of side walls 2d is formed. Similarly, the second clip member 3 has an end wall 3c and a pair of side walls 3d. As can be seen from FIGS. 1 and 2, the first clip member 2 is sized to cover the outside of the second clip member 3. As clearly shown in FIG. 3 and as can be seen from FIG. 2, a rectangular cutout opening 3 e is formed in the flat portion 3 a of the second clip member 3. Similarly, the first clip member 2 is also formed with a rectangular notch opening 2e. The main portions of the clip members 2 and 3 are constituted by the flat portions 2a and 3a including the pinching engagement edges 2b and 3b, the end walls 2c and 3c, and the side walls 2d and 3d.

  Referring to FIGS. 1 and 4, each side wall 2 d of the first clip member 2 is formed with a semicircular projecting portion 2 f projecting outward from the edge portion at a substantially intermediate portion in the length direction. . As shown in FIGS. 5, 6, and 7, the first clip member 2 is formed with a post 2g projecting inward from the flat portion 2a at a position closer to the inner side in the width direction than the overhanging portion 2f. A hinge pin 2h is formed between the side wall 2d and the post 2g. As a matter of course, the hinge pins provided between the side wall 2d and the post 2g on both sides are substantially coaxial with each other.

  Referring to FIGS. 8, 9, and 10, both side walls 3 d of the second clip member 3 receive hinge pins 2 h at the edges in the front-rear direction corresponding to the hinge pins 2 h of the first clip member 2. The bearing portion 3f is formed. As shown in FIG. 11, the bearing portion 3 f has a partially circular shape whose upper part is open, and the width of the upper open part is slightly smaller than the maximum diameter of the partially circular circle.

  Referring to FIGS. 5, 6 and 7 again, the first clip member 2 is inclined at an angle with respect to the flat portion 2a from the edge of the notch opening 2e closer to the clip engaging edge 2b. The elastic piece 4 is formed integrally with the main body portion of the clip member 2. As can be seen from FIG. 5, the direction in which the elastic piece 4 extends is substantially along the edge of the side wall 2d. The end of the elastic piece 4 is a free end, and an engaging portion 4a bent outward is formed at the end.

  Referring to FIGS. 8 and 10, the second clip member 3 is inclined with respect to the flat portion 3e from the edge closer to the sandwiching engagement edge portion 3b of the notch opening 3e formed in the flat portion 3a. The elastic piece 5 extending so as to form an angle is integrally formed. As in the elastic piece 4, the elastic piece 5 is also formed with an engaging portion 5 a bent outward at the free end of the terminal.

  1 and 2 show the completed clip 1 with the first and second clip members 2, 3 assembled. The clip members 2 and 3 are brought into contact with the engaging portions 4 a and 5 a of the elastic pieces 4 and 5, and the hinge pin 2 h of the first clip member 2 is fitted to the bearing portion 3 f of the second clip member 3. Assembled. In this state, both elastic pieces 4 and 5 are elastically pressed against each other, and the pinching engagement edges 2b and 3b of the clip members 2 and 3 are pressed in the mutual direction by the elasticity. FIG. 12 shows the clip 1 in an opened state. The clip 1 opens the clip in the normal clip by pushing the clip members 2 and 3 toward each other on the side far from the edge portions 2b and 3b for pinching engagement. The elastic pieces 4 and 5 can be elastically bent to the state shown in FIG. That is, the side of the clip members 2 and 3 that is far from the pinching engagement edges 2b and 3b constitutes the clip engagement release operation section.

  The elastic piece is not necessarily provided on both the first and second clip members 2 and 3. That is, one clip member is provided with an elastic piece, and the other clip member is formed with an engagement member that receives the end of the elastic piece provided on the one clip member. In this case, the elastic piece formed on the one clip member has an inclination angle larger than the illustrated shape.

  The clip members 2 and 3 can be made of any material as long as it is a hard plastic material that can be molded using injection molding or other plastic material molding techniques. Typical plastic materials are polypropylene, ABS resin, and PMMA, and a transparent material is preferable. Since the clip members 2 and 3 are integrally formed with the main body portion and the elastic piece, there is no need for a separate spring part such as a metal coil spring, and the number of parts is less than that of the conventional clip, and the clip members 2 and 3 are assembled. Less man-hours are required.

  As one embodiment of the present invention, the clip members 2 and 3 can be configured to emit light in a dark place. For this purpose, in this form of the invention, a luminous material is mixed into the plastic material. The phosphorescent substance is a substance that receives light energy, accumulates the light energy, and generates light in a dark place. Typical phosphorescent materials include zinc sulfide-based and calcium sulfide-based materials. The addition ratio of the phosphorescent material may be 5 to 20% in terms of the weight ratio to the total weight.

  According to the configuration of this embodiment, since the clip members 2 and 3 emit light when placed in a dark place, their positions can be known without turning on the illumination lamp, which is impossible with the conventional clip. Can be used. As another configuration, a luminous film may be formed on the molded clip member instead of adding the luminous substance to the plastic material. In this case, the coating film of the phosphorescent paint does not necessarily need to be formed on the front surface of the clip member, and the object can be sufficiently achieved by forming only on a part thereof.

  Further, it is possible to attach or embed a magnet 6 to one of the clip members, for example, the clip member 3 as shown in FIG. According to this configuration, the clip 1 can be attached to a magnetic material portion such as a refrigerator outer wall.

  The clip of the present invention is not limited to the shape shown in the above embodiment, and can be implemented in various forms.

It is a side view shown in the state where the clip by one embodiment of the present invention was closed. It is a longitudinal cross-sectional view of the clip shown in FIG.
