Description

[Detailed Description of the Invention] This invention relates to a writing instrument clip attachment device that is removably fitted on the outside of a sheath.

In a conventional clip attachment device for a writing instrument that is detachably attached to a sheath, a C-shaped holding portion of the clip is fitted onto the outside of the sheath. Therefore, if the fitting force of the holding part is weak, the clip will come off when carrying it and the writing instrument will be lost.If the fitting force of the holding part is strong, the clip will not come off and the clip will hit your hand when you write, interfering with your writing. At the same time, it also had the disadvantage that the surface of the sheath would be damaged when the clip was attached or removed.

This device fits the locking pieces provided on the end faces of the fixed part of the clip onto the inner surface, front and rear sides of the raised engaging part of the sheath, and also abuts the mutually opposing end faces of the fixed part. The configuration allows the clip to be easily and securely attached when needed.
The object of the present invention is to provide a writing instrument clip attachment device that can be easily removed when unnecessary.

The structure of this device will be explained based on the drawings. As shown in FIG.
A, a part thereof is provided with two linear cut grooves 1B extending in the axial direction, and a portion between the cut grooves 1B is raised outward to form an engaging portion 1C. 1. Alternatively, as shown in FIGS. 2 and 3, the sheath 11 is constructed by injection molding, and the engaging portion 11C is provided at an appropriate position on the narrow diameter portion 11A.
The sheath 11 may be configured by providing a cutout groove 11D on the side of the sheath 11. On the other hand, the fixed part 2A integrated with the clip 2 is pressed into a cylindrical shape, and the end surfaces 2B and 2C of the fixed part 2A are brought into contact with each other so as to face each other.
The clip 2 is configured to have elasticity. Alternatively, the clip may be constructed by injection molding, and the kerf provided in the cylindrical fixing part may be located on the substantially opposite side of the clip, so that the fixing part has elasticity. Two cutout portions 2D are provided on one end surface 2B of the fixing portion 2A of the clip 2 configured as described above.
is provided to constitute a trapezoidal locking piece 2E located between the two notches 2D, and the clip 2 shown in FIG.
Configure. It should be noted that there is no problem whether the locking piece 2E is provided on the end surface 2C or on both the end surface 2B and the end surface 2C. The fixing part 2A of the clip 2 is placed over the engaging part 1C of the sheath 1 from the rear, and is fitted into the narrow diameter part 1A of the sheath 1. Thereafter, the fixing part 2A of the clip 2 is rotated in the axial direction so that the locking piece 2E side moves forward in the circumferential direction, and in the case of the sheath 1 shown in FIG. The inner surface 1E, the front side 1F, and the rear side 1G are press-fitted together, and the end surface 2B and end surface 2C of the fixing part 2A are in contact with each other, and the sheath 1 is fitted as shown in FIGS. Attach clip 2. When removing the clip 2, rotate the fixing part 2A of the clip 2 in the axial direction so that the locking piece 2E side retreats in the circumferential direction, and the locking piece 2E will come off from the engaging part 1C of the sheath 1. At the same time, the end face 2C of the fixed part 2A that does not have the locking piece 2E rides on the engaging part 1C, and in this state, if the clip 2 is moved backward, the clip 2 can be easily removed.

In the case of FIGS. 2 and 3, the inner surface 11E of the cutout groove 11D of the engagement portion 11C of the sheath 11 and the front side 11
F and rear side 11G, locking piece 2E of clip 2
What is necessary is just to pressure-contact and fit, and to make end surface 2B and end surface 2C of fixed part 2A contact.

In all of the embodiments described above, a small diameter part is formed at the rear of the sheath.If the part is formed into a small diameter part, the outer surface of the fixing part of the clip matches the outer surface of the sheath, which improves the appearance. A special effect is obtained in that the sheath is not moved forward more than necessary, but it is not necessarily necessary to construct the rear part of the sheath with a narrow diameter part, and even if the sheath is constructed in a simple cylindrical shape, the effect of this invention will be impaired. isn't it.

In the present invention described above, the locking pieces provided on the end faces of the fixing part of the clip are fitted to the inner surface, front side, and rear side of the raised engagement part of the sheath, and the end faces of the fixing part facing each other are fitted. By making the clips in contact with each other, the clip can be easily attached and detached by simply removing the locking piece of the clip from the engagement part of the sheath and fitting it together. Moreover, when attaching the clip, the clip does not move forward, backward, left or right, and is securely attached. The object of the present invention is to provide a writing instrument clip attachment device that can be attached to a writing instrument and easily removed when unnecessary.
