Description

[Detailed Description of the Invention] The present invention relates to a clip device for a writing instrument with a cap. This invention relates to a clip device for a writing instrument with a cap, which causes the clip to protrude from the outer peripheral surface of the cap when the cap is fixed to the front of the writing instrument.

Conventionally, clips that are fixed or inserted in a state where the clip is always protruding have a poor feel when writing, and the problem with sharp pencils is that the width of the handwriting changes due to one side of the lead slipping. It had

In this way, by changing the outward protrusion of the clip when writing and when carrying it,
It has extremely great functional effects, and for this reason, there are also known clip devices in which the clip is moved in and out by manipulating the clip. Requires operations such as sliding in the direction,
This could not be said to be favorable in terms of operability.
In addition, when the cap is attached to and removed from a writing instrument, the clip automatically appears and disappears, and as a device to eliminate the troublesome operation of appearing and appearing, Utility Model No. 48-58833 was developed.
No. 1 is also known, but in this invention, a spring base body equipped with a spring piece is inserted and fixed into the cap, and the spring piece is configured to elastically repel the clip outward, so that there is no method of projecting the clip. However, there remains the problem that sufficient clamping force cannot be applied to the clip when the clip is projected.

Therefore, the purpose of the present invention is to prevent the clip from quickly appearing and disappearing when the cap is attached to and removed from the writing instrument, and
To provide a clip device for a writing instrument with a cap capable of imparting sufficient clamping force to a protruding clip.

Hereinafter, the present invention will be explained in detail based on the accompanying drawings, and in this example, a knurled mechanical pencil was used as the writing instrument.

1 to 5 show a first embodiment of the present invention, and A indicates a cap. Reference numeral 1 denotes a cap tube made of resin or metal, and the cap tube 1 has a longitudinal groove 2 on its outer surface, and has an inclined guide portion 3 at a position facing the groove 2 inside the rear part. A clip attachment member 4 is disposed so as to be resiliently pushed forward by a resilient member 5 such as a coil spring stretched between the clip attachment member 4 and the shaft cylinder 1. More specifically, as shown in the enlarged view of FIG. 2, the inclined guide portion 3 of the mounting member 4 has a longitudinal notch 3a and
It is constituted by fitting grooves 3b provided on both sides of the slanted side walls of a. Reference numeral 6 is a pressing body which is resiliently disposed forward by a resilient member 7 made of a coil spring, magnet, etc. stretched between the clip attachment member 4 and the cap barrel 1. As shown in FIG.
It protrudes from the rear end of the cap barrel 1 so that it can be pressed, and it does not need to be a writing instrument other than a lock-type sharp pencil. Reference number 8 is
The clip 8 is disposed in the groove 2 of the cap barrel 1, and the clip 8 has a base 9 attached to the fitting groove 3b of the inclined guide part 3 of the attachment member 4, a leg 10, and a front inner surface that is clamped. A clamping part 12 having a protrusion 11 and a clamping receiving part 1 whose front end is fixed to the cap barrel 1
3, however, the cap barrel 1 may be substituted for the clamp receiving portion 13. Incidentally, reference numeral 14 is a recessed portion for fastening.

Reference numeral B indicates a knock-type mechanical pencil, which is similar to a normal hammer-type mechanical pencil, and although the details are omitted, 15 is a barrel, 16 is a knob cap, and 17 is a protrusion provided on the outer surface of the barrel 15. .

Next, the operation will be explained with reference to FIGS. 4 and 5.

When the cap A is fixed to the rear part of the lock-type sharp pencil B, the rear end surface of the barrel 15 presses the clip attachment member 4 backward against the elastic force of the elastic member 5, so that the clip 8 The base portion 9 is guided by the fitting groove 3a of the inclined guide portion 3 of the clip attachment member, and the gripping portion 12 is recessed into the groove 2 provided in the cap barrel 1, so that it is substantially flush with the outer peripheral surface of the cap barrel 1. Along with this operation, the knock cap 16 presses the front end surface of the pressing body 6, so that the pressing body 6 retreats against the elastic force of the resilient member 7, which is provided to be smaller than the knock pressure.
It protrudes from the rear end surface of cap A. After this series of operations, the recess 14 provided on the inner surface of the front end of the cap barrel 1
The cap A and the knob-type sharp pencil B are fitted and secured by the protrusion 17 provided on the outer circumferential surface of the shaft cylinder 15 (see FIG. 4).

When the cap A is fixed to the front part of the lock type sharp pencil B, the cap A and the sharp pencil B are fitted and fixed by the recess 14 and the protrusion 17.
Since the clip 8 is not acted upon, the base 9 of the clip 8 is located behind the inclined guide part 3 of the clip attachment member 4 which is resiliently repelled forward by the resilient member 5, and the gripping part 12 of the clip 8 is, cap barrel 1
(See Figure 5).

The clipping device according to the present invention can be modified in various ways other than the embodiments shown in FIGS. 1 to 3, and FIGS. 6 and 7 show examples thereof. This example differs from the first example in the clip and the clip attachment member. That is,
The clip 108 omits the clamp receiving part, and
The base portion 109 is annular, and the clip attachment member 104 has a guiding slope portion 103.
, the longitudinal notch 103a, and the notch 10
A longitudinal annular fitting groove 103b continuous with 3a.
It is composed of the following.

For convenience, the present invention has been shown using a cap-type sharpener pencil, but by making conventional design changes, it can also be applied to various writing instruments such as ballpoint pens and fountain pens that use water-based or oil-based inks. It is something.

As described above, the present invention allows the clip to be automatically and quickly retracted using the inclined guide portion of the clip attachment member when the cap is attached to or removed from the writing instrument, and even when the protruding clip is pulled upward. Since the clip does not move in the axial direction, it has the practical effect of providing sufficient clamping force to the clip.

Incidentally, in the present invention, even if an eraser is installed at the rear of the pressing body 6 or an appropriate means such as screwing is used as a means for fixing the cap and the writing instrument, the gist of the present invention will not be changed in any way. .
