OFFICE CLIP

Abstract

The present invention provides an office clip having a high designability while having a sufficient gripping force. It is an office clip for pinching and binding paper, wherein a ring portion of elastic wire is spirally wound closely or at a predetermined pitch, with at least one end wire of the ring portion being extended inward with respect to the center of the spiral axis, and the end wire being bent toward the direction of the other end of the ring portion, heightening the clamping force and enhancing the designability by one motif created by the end wire.

BEST MODE FOR CARRYING OUT THE INVENTION

[0030] Embodiments of the present invention will be described in detail below with reference to the drawings. The present invention is not limited to the following embodiments and examples shown in the figures, and the present invention can be variously changed in design.

Embodiment 1

[0031] FIG. 1 is an external view of an office clip of Embodiment 1, (1) showing a front view and (2) showing a rear view. As shown in FIG. 1 (1), the office clip 1 is formed by processing one metal wire rod, and the office clip includes a ring portion 2 and end wire rods (3, 4).

[0032] Specifically, as shown in FIGS. 1 (1) and (2), in the ring portion 2, the wire rods are spirally wound in a close manner, and the wire rods are formed with a sandwiching portion 2a where the wire rods come into contact with each other and a non-holding portion 2b where the wire rods do not contact each other. The spirally wound length is about one round and two thirds of the spiral, where “about” means within one-tenth of a round.

[0033] FIG. 2 is an external view of an office clip of Embodiment 1, wherein (1) is a left side view and (2) is a right side view.

[0034] As shown in FIG. 2 (2), in the sandwiching portion 2a, a front side wire 2c and a back side wire 2d come into contact with each other, and the elastic force of each wire allows the memo paper or the like to be pinched.

[0035] As shown in FIG. 1 (1), the end wire rod 4 is extended toward the center of the circle of the front side wire 2c at the sandwiching portion 2a and extended further from the substantial center. Further, as shown in FIG. 1 (2), the end wire rod 3 is extended toward the center of the circle of the back side wire 2d at the sandwiching portion 2a. As a result, the end wires (3, 4) are united to create one motif.

[0036] Further, as shown in FIG. 2 (1), the end wire 3 is provided by bending in the spiral axial direction of the ring portion 2 and toward the other end of the ring portion 2. As a result, the gripping force during use is increased. On the other hand, the end wire 4 is not bent.

[0037] A mechanism for improving the clamping force as mentioned above will be described with reference to FIG. 3. FIG. 3 is an explanatory drawing of an office clip of the present invention, wherein (1) represents a clip in a closed state, (2) represents a clip in an open state and (3) represents a state after clipping, as plane figures of each state.

[0038] As shown in FIG. 2 (1), in the office clip 1, only one end wire 3 is provided in the spiral axial direction and towards the other end of the ring portion. However, in the office clip 10 of FIG. 3 (1), both end wires (30, 40) at the ring portion 20 are each disposed in the axial direction of the spiral and the direction of the other end of the ring portion.

[0039] Here, after opening the clip in the direction shown by the arrows (9a, 9b) in FIG. 3 (2), the memo paper 8 is sandwiched as shown in FIG. 3 (3), and the memo paper 8 can be held by the office clip 10. At that time, since the end wire (30, 40) is bent in the spiral axial direction and in the direction of the other end of the ring part 20, the elastic force is exerted in the direction indicated by the arrows (9c, 9d), and the tip portions of the end wire rods (30, 40) are firmly brought into contact with the memo paper 8 and thus the memo paper can be held.

[0040] FIG. 4 is an explanatory view showing a usage state of the office clip of Embodiment 1, with (1) showing a front view and (2) showing a rear view. As shown in FIG. 4, the office clip 1 holds the memo paper 8 in between. In such a state, it is not possible to grasp all the designs provided on the office clip 1, but when the office clip 1 is removed, the design of the clip appears, and it becomes possible to entertain the viewer in the office.

Embodiment 2

[0041] FIG. 5 is an external view of an office clip of Embodiment 2, (1) showing a front view and (2) showing a rear view. As shown in FIG. 5, the office clip 11 is formed by processing a single metal wire rod as in Embodiment 1, and includes a ring portion 21 and end wire rods (5, 6).

[0042] However, unlike Embodiment 1, the ring portion 21 of the office clip 11 has an elliptical shape, and the end wire rod 5 and the end wire rod 6 cross each other, which creates one motif by unification of end wire rods 5 and 6, resulting in a shape of high designability.

[0043] Thus, even when the end wire rods intersect with each other, the end wire rod 6 is not provided by bending the entire end wire rod 6 in the spiral axial direction and toward the other end of the ring portion, but by bending only a tip portion 6a of the wire 6 as shown in FIG. 5 (1), it is possible to enhance the clamping force. Similarly, with regard to the end wire 5 as well, it is possible to strengthen the clamping force by bending only a tip 5a as shown in FIG. 5 (2).

[0044] FIG. 6 is an explanatory diagram illustrating a usage state of the office clip of Embodiment 2. As shown in FIG. 6, an office clip 11 holds the memo paper 8.

[0045] In a similar manner to Embodiment 1, the design is such that the original design is expressed when the office clip 11 is removed from the memo paper 8, namely, when the office clip 11 is not in use.

Embodiment 3

[0046] FIG. 7 is an external view of an office clip of Embodiment 3, where (1) is a front view and (2) is a rear view.

[0047] As shown in FIG. 7, unlike Embodiment 1, the office clip 12 has only one end wire rod 7 of the ring portion 21 extending toward the inside of the ring.

[0048] The spirally wound length is about one round and two-thirds of the spiral, as in Embodiment 1, and therefore, the sandwiching portion 21a occupies about two-thirds of the ring portion 21. In addition, since the end wire 7 is provided by bending in the spiral axial direction and in the direction of the other end of the ring part, a sufficient gripping force can be obtained, and thus it becomes possible to create a design by processing only one end of the ring portion.

OTHER EMBODIMENTS

[0049] Unlike Embodiments 1 to 3, the ring portion may be configured in such a way that the front side wire and the back side wire in the sandwiching part do not come into close contact with each other and are wound at a predetermined pitch.

INDUSTRIAL APPLICABILITY

[0050] The present invention is useful as an office clip.
