Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cap with an opening/closing lock, and more particularly to a cap with an opening/closing lock for pens, tools, etc. in which it is undesirable to expose the pen tip or needle tip for a long period of time.

BACKGROUND OF THE INVENTION Various caps have been devised to protect parts such as the nib of a pen or the sharp tip of a tool when not in use.

A well-known conventional cap is one in which the entire cap is attached to and removed from a pen or tool.

Problems to be Solved by the Invention However, for example, in quick-drying vents used to inspect through-hole plating parts of printed circuit boards in assembly lines and check whether they pass or fail, the entire cap must be removed and attached % frequently each time the inspection is performed. This is a huge burden on the inspector and is also very inefficient.

On the other hand, if the cap is constantly removed during assembly line work, the burden on the inspector is reduced, but there is a problem in that the life of the quick-drying pen is significantly shortened.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cap with an opening/closing lock that allows the cap to be attached and detached from the tip of a pen or tool with extremely simple operation and efficiency.

SUMMARY OF THE INVENTION The present invention comprises a cap body, an actuator pivotally connected to the cap body at one end, and a crank pivotally connected to the other end of the actuator. An arm is pivotally connected to the crank and the cap body and has a cap fixed to its tip, and is provided between the actuator and the cap body for urging the actuator upward and pushing the actuator towards the one side. A spring is provided for rotation about the end.

The arm pivots about a pivot point with the cap body, and the longitudinal axis of the crank is aligned with the pivot point between the arm and the cap body when the cap is opened and locked. The locking cap solves the problems of the prior art described above.

The actuator is pivotally connected to the actuator, and is rotatably connected to the crank J by a pink pin, so that the rotating movement of the crank J causes the actuator to rotate about the connecting axis t with the cap body l. It consists of an arm j and a cap 6 fixed to the tip of the arm j.

The cap body l is shown in Fig. 3 (a), (b),
As shown in detail in (c), the cap body has a substantially cylindrical shape, and the inside of the cap body must have a space 33 for attaching the pen to OK. A recess 10 is formed on the surface of the cap body 1, and the recess 10 is for preventing a worker's hand from slipping when gripping the cap body 1 during work. Also, the cap body/Fi,
One end is equipped with a pin receiver for rotatably attaching the actuator, insert pink into this pin receiver and the pin receiver of the actuator, and attach it to the actuator's cap body. It looks like this. A bearing n is provided near the other end of the cap body l, and a shaft S is attached to this bearing n.
is received to rotate arm j around axis t. The inner surface J'l of the other end of the cap body is frustoconically or tapered to receive the tip of the pen 100.

Further, an opening J/ is provided at the tip of the other end of the cap body/, and the pen tip iot of the pen 100 is inserted through this opening J/.
is now able to stand out. The outer surface 30 of the other end of the cap body l has 1. It has a frustoconical shape, and this outer surface 3Q forms a contact surface against which the three inner surfaces of the cap base come into contact when the cap 6 is closed, and the inner surface of the cap base or the cap body/ The interior of the pen is completely isolated from the outside environment to prevent the nib from drying out.

The construction of the actuator 2 and the crank J is shown in detail in FIGS. 3c-d) to (1). The actuator has a pin receiver l at one end for receiving the pink for connection with the cap/, and a pin receiver for receiving the pink for connection with the crank J at the other end. Further, a spring receiving recess for receiving the spring 13 is formed at the lower part of the actuator. The spring 3 is bent and attached by a spring pin attached to the actuator.
The upper half part /Ja of the spring /J is engaged with the upper surface l of the spring receiving recess, and the third half part /Jb of the spring /3 is engaged with the upper surface l of the cap body l. When the cap 6 is open, the spring /J is compressed and the angle formed between the upper half /ja and the lower half /3b of the spring /3 is small and the actuator is pressed against the upper surface l of the cap body l. When the cap 6 is closed, the spring /JFi is expanded, and the spring 13
The angle formed by the upper half /ja and the lower half /Jb is large, and the actuator is placed in a position where it is suspended at a certain angle with respect to the top surface /ub of the cap body, that is, as shown in Fig. 1(b). On the underside of one end of the zero actuator to hold it in the
As shown in the figure, a notch /j is provided, and the surface of the notch lta comes into contact with the surface of the cap body l when the cap 6 is closed. In addition, a non-slip plate is carved on the top surface of the single actuator to prevent the operator's hand from slipping during work. crank J
is equipped with a pin receiving arm for receiving a pin 9 for connection with the actuator, and a pin receiving arm for receiving a pin 9 for connection with the arm S. The crank J transmits the rotation of the actuator around the pin l to the arm 2 and the cap 6. When the cap 6 is closed as shown in Fig. 1, the longitudinal axis of the crank J is , A-A shown in FIG.

In addition, when the cap 6 is opened as shown in Figure 1, the longitudinal axis of the crank 3 is located along the -B' line as shown in Figure 1, and the cap 6 is locked and opened. maintained in the state. That is, in this state, the crank 3 is pressed toward the shaft and locked by the biasing force of the spring 3 in the actuator. To release this lock, simply press the actuator with the pen tip facing down. At this time, the pressure of the crank J against the pink is released, and the weight t of the pen tip causes the arm 3 to rotate counterclockwise, and the crank 3 can also rotate accordingly.

Cap 6 and arm! The configuration of is shown in Figure 3 (j) to (
C) is shown in detail. The cap 6 has three frusto-conical inner surfaces that come into contact with the outer surface or contact surface 30 of the tip of the cap body l. The cap base is an arm due to axis invasion! is fixed to. The arm 5 has a bearing J that receives the shaft t for connection with the cap body/
and a pin receiver 1 that receives a pin for connection with the crank 3, and furthermore, when the cap is opened, it comes into contact with the outer surface of the bearing t of the cap body and prevents further rotation of the arm. Equipped with protrusions.

Figure 3 (0) is a front view and a plan view of pink, respectively. Only pink is shown here, but the composition is similar to that of other pinks, including pink.

The operation of the opening/closing lock row cap configured as above is performed in the ninth step.
This will be explained using figures.

In FIG. 4, solid lines indicate the positions of each member when the cap 6 is open and locked, and broken lines indicate the positions of each member when the cap 6 is closed. It is also assumed that a cap with an opening/closing lock is already attached to the Pen 100K. The attachment operation to the pen ioo is performed in the same manner as a conventional cap, and at this time, the nib 10/ of the pen 10Q protrudes from the opening J/ of the cap body l.

First, the operation from the open state of the cap 6 as shown by the solid line in FIG. 1 to the closed state of the cap 6 as shown by the broken line in FIG. 4 will be explained.

When the cap 1 is open, the actuator is positioned almost parallel to the cap body l, and the spring JFi in the spring receiving recess l of the actuator, the upper half /ja and the lower half iJb.
are compressed so that they are almost parallel. Also, the pink that connects the actuator and crank J, and the crank J and arm! and the axis t that connects the arm j and the cap body l are positioned on a straight line shown by line B-B', and in this state, the biasing force of spring /3 against the actuator is is applied in the direction of line B-8', and the crank 3 is connected to the pin receiver 26. It is pressed against the pin 9.7 at the end, thereby locking the crank, 72 and the actuator so that they cannot rotate upward.

When the cap 6 is open and locked in this way, if you lightly press the actuator toward the cap body l, the pressure on the pin 9.7 of the crank J will be released, that is, the lock will be released, and the crank 32 will be released. The actuator is rotatable around the pin or axis t. However, arm! Since the protrusion l/ is in contact with the bearing of the cap body l, the crank JFi will not rotate clockwise from this state.

Next, point the pen tip 10/down to see the cap 6 and the arm! Arm j2 and cap 6 rotate counterclockwise due to their own weight, and in conjunction with this, crank J rotates counterclockwise around the shaft. Rotates clockwise around pink. When the notch 13 of the actuator comes into contact with the surface of the cap body l as indicated by the symbol isa, the rotation of the actuator stops, and the actuator is positioned at the position indicated by the symbol a. Ru. In conjunction with the clockwise rotation of the actuator J, the crank J rotates counterclockwise and moves to an upper position as shown by reference numeral 3a. As a result, the pink connecting the crank 3 and the actuator moves to the position indicated by the symbol d a, and the pink connecting the crank 3 and the arm j moves to the position indicated by the symbol 7a. At this time, pink, pink, and pin t are positioned on a straight line as shown by the line A-A/. When the pink rotates counterclockwise to the position indicated by 7a, the arm j rotatably connected to the pink rotates 11C/10'' counterclockwise about the axis t, code ja
The cap 6 fixed to the tip of the arm j is rotated by 10" to the position 4a. As a result, the three inner surfaces of the cap 6 are brought into contact with the cap body. 30 and blocks the inside of the cap 6 or the inside of the cap body 1 from the external environment, thereby preventing the pen tip 10/ from drying out.

In this way, while holding the Ben 100 in the working state, the lock is released by pressing lightly on the actuator with one finger of the hand holding the Ben 100, and the cap 6 is changed from the open state to the closed state. state can be automatically transferred.

Next, the operation from the closed state to the open state of the cap 6 will be explained.

As shown by the broken line in Figure 4, when the actuator is pushed towards the cap body when the cap 6 is closed, the actuator rotates counterclockwise around the pink part, and Then, crank J&, pins 7 and 9 rotate clockwise. The spring 13 is rotated counterclockwise by the actuator.
is gradually compressed, and when the operator releases the hand during rotation of the actuator, the actuator returns to its original state due to the upward biasing force of the spring 13, that is, the state in which the cap 6 is closed. Continue to push the actuator toward the cap body l, and when the protrusion l/ provided on the arm 3 rotates clockwise from the position shown by the symbol //a and abuts against the cap body l, the crank 3 The longitudinal axis of the is positioned on the line B-B', that is, the axis t is positioned on the straight line indicated by the line B-B', and the biasing force applied from the spring/JK to the actuator is applied. The direction is on the line B-B', and the pin 9.7IC of the crank 3 is pressed against the bearing and core, and the rotation of the crank J is locked, so even if you take your hand off the actuator, the actuator will not move. The cap 6 does not return to the closed state. At this time, arm 2 and cap 6
are rotated by 10° clockwise from the positions indicated by symbols ja and 6a, respectively, so that they are positioned behind the pen tip 101 on the remote, so that they do not get in the way when the worker applies the pen tip to the work part. It won't happen.

In this way, while holding the Ben ioo in the working state, simply push the pen 100 with one finger of the damaged hand until the protrusion/l of the arm j abuts the cap body l, and the cap is removed. 6 can be moved from a closed state to an open state.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, when the cap is open, the longitudinal axis of the crank is locked in line with the pivot point between the arm and the cap body, so that the operation is not possible. Even if you take your hand off the pen, the cap remains open until 1999. To close the cap from this state, press the actuator lightly to release the lock, and then point the pen tip downward to open the cap and the arm. , the crank and the actuator are rotated by the weight of the cap, the arm 2, and the biasing force of the spring, and automatically shift to the closed state, and when opening the cap from the closed state, the actuator must be pushed to the above-mentioned locked state. Since it is only necessary to move the cap, opening and closing of the cap can be controlled with just one finger of the hand holding the pen or tool. For example, if you use the pen for a long time, such as when checking the pass/fail inspection of the through-hole plating part of a printed circuit board, and the pen is quick-drying, you should cap it each time unless you are using the pen tip to hit the through-hole plating part. The cap with opening/closing lock of the present invention allows the cap to be opened and closed easily and quickly even when it is necessary to cover it with a lid.This makes inspection work extremely efficient, and significantly reduces the burden on the operator. This has the effect of extending the life of the pen.
