Description

[Detailed description of the invention] This invention relates to a writing instrument cap with a digital clock.

In conventional caps, an inner cap is placed inside an outer cap, and a clock module attached to the top side of the inner cap faces a see-through plate attached to the side of the outer cap. Even if it is securely attached to the cap, the inner cap is likely to slip out or rotate due to the pulling and rotating forces exerted on the inner cap when inserting and removing the pen part of the writing instrument from the inner cap. There was a problem that the internal structure of the device was not stable.

The purpose of this invention is to provide a writing instrument cap that can prevent the inner cap from slipping out and rotating, thereby stabilizing the built-in timepiece module, and which can be assembled quickly.

To explain this invention based on the drawings, the cap includes an outer cap 1, an inner cap 2, a clock module 3, and a transparent plate 4.

The outer cap 1 is provided with a battery accommodating part 6 which is detachably connected to the crown 5 at the top of the opening, and a watch module insertion hole 7 is provided on the side of the outer cap 1.
Inner surface has a recess-like pull-out prevention part 8 and a groove-like rotation stopper part 9
are sequentially provided from the top side of the outer cap 1 toward the mouth of the outer cap 1. 10 is a battery, 11 is a conductive coil spring, 12 is a clip attachment part, 13
is a clip.

The inner cap 2 has a protrusion 14 and a protrusion locking part 1 on the outer surface.
5 are sequentially provided from the top side of the inner cap 2 toward the mouth of the inner cap 2, a stand 16 is formed on the top side of the inner cap 2, and the protrusion 14 is fitted into the slip-off prevention part 8 of the outer cap 1. The inner cap 2 is disposed within the outer cap 1 by fitting the locking portion 15 into the rotation preventing portion 9.

The clock module 3 is smaller than the clock module insertion hole 7 of the outer cap 1, and is smaller than the clock module insertion hole 7 of the inner cap 2.
It is installed on. 3' is a crystal oscillator.

The see-through plate 4 is made of an elastic material, has a shoulder 17 formed at its edge, and is connected to the edge 18 of the outer cap 1 forming the watch module insertion hole 7 so as to face the watch module 3. A time display operation button 19 is passed through the transparent plate 4.

In this example, the rotation stopper of the outer cap is formed into a groove, but this may be used as a protrusion to fit into the groove-shaped locking part of the inner cap.

In addition, if the outer cap is provided with a clock module insertion hole that is larger than the clock module, the clock module can be assembled by inserting it into the cap through the clock module insertion hole. The assembly can be easily assembled without performing the temporary alignment required when inserting and storing the watch module, that is, aligning the axis of the watch module with the axis of the see-through plate attached to the cap outside the cap in order to determine the position of the watch module relative to the see-through plate. can be done quickly.

When the writing instrument body is inserted into or removed from the cap configured as described above, the rotation stopper of the outer cap engages with the locking part of the inner cap, which resists the force that tries to rotate the inner cap. The inner cap can be prevented from rotating, and since the outer cap's pull-out prevention part engages with the protrusion on the inner cap, this prevents the inner cap from slipping out against the force that tries to pull the inner cap. can be done.

As explained above, this device engages the outer cap's slip-off prevention part and rotation stopper with the inner cap's protrusion and locking part, respectively, and also provides a clock module insertion hole that is larger than the clock module on the side of the outer cap. This simple structure prevents the inner cap from slipping out and rotating, allowing the watch module to be stably housed, and also enables quick assembly because the watch module can be inserted through the watch module insertion hole.
