Description

  The present invention relates to a lighter ignition operation assisting tool that is used by being attached to a lighter having a push-in or slide-type switch.

A piezo lighter is a lighter that uses a piezoelectric element to ignite, and discharges due to an impact when the ignition switch is pressed, and this is ignited by igniting the fuel gas. This piezo lighter There are two types of ignition switches: a push-in type ignition switch that pushes down directly and a slide type ignition switch that has a rotating shaft and slides the ignition switch diagonally downward.
Since this piezo-type lighter can be ignited simply by pushing (or sliding) the ignition switch, even a child can easily perform the igniting operation. For this reason, there is a risk that the child may ignite by operating the lighter in an interest-oriented manner, or may ignite by operating the lighter erroneously, leading to a serious accident.

In order to prevent such operations and erroneous operations by children, there are also piezo-type lighters that have a lock mechanism on the ignition switch, but since the lock mechanism is provided on the lighter itself, the child can play with the lighter. In the meantime, the locking mechanism may be released, or the user may forget to lock after using the lighter. Therefore, the conventional locking mechanism has not always ensured safety.
Japanese Patent Laid-Open No. 2004-20022

On the other hand, a piezo lighter has been developed in which the ignition switch itself has been improved so that the ignition switch cannot be operated unless the force is stronger than before in order to prevent the child from performing the ignition operation.
This method does not lock the ignition switch by providing a lock mechanism on the lighter separately from the ignition switch, but increases the operating force required for operation of the ignition switch (push-button cigarette lighter has a pushing force of 42 N). (Newton) Above, with a sliding cigarette lighter, the rotational force is 20N or more. 1N is 0.11097kgf (weight kilogram). There is no risk of unlocking and operating the ignition switch by mistake. This type of ignition switch is called a weighted ignition switch.
“JIS S 4803: 2010 Cigarette lighter and multi-purpose lighter-Safety measures for infants (child resistance function) by operating force” p. 4

However, in a piezo-type lighter that employs this weighted ignition switch, it is natural that a stronger force than before must be applied when operating the ignition switch. Even when using, a strong force is required, and there is a problem that operability is worse than the conventional one. This poor operability is particularly noticeable for women with weak grip and elderly people.
In addition, at the manufacturing site, inspection work is required to check whether the manufactured lighter is properly ignited, and the operator must operate an ignition switch with poor operability when performing inspection. In addition, not only is the work efficiency poor, but the worker causes tendonitis, which imposes a physical burden on the worker.

  On the other hand, lighters sold in Japan after September 27, 2011 must comply with the national technical standards based on the Consumer Product Safety Act. When it is adopted, the above-mentioned operating force is required, and those that do not satisfy this cannot be sold.

  An object of the present invention is to obtain a lighter ignition operation assisting tool that assists the operation of an ignition switch to improve operability when a lighter having a push-in type or a slide type switch is normally used. .

  The lighter ignition operation assisting device of the present invention is an ignition operation assisting device that is detachably attached to a lighter having a push-in type or a slide-type switch, and is formed to have a substantially U-shaped cross section. A frame having a surface and a locking portion for locking the lighter body, and an ignition operation auxiliary means disposed above the ignition switch of the lighter to assist the operation of the ignition switch when the lighter is mounted. The base end is pivotably attached to the upper end of the ignition hole when the lighter is attached to the frame via a mounting shaft, and the other end is a free end protruding from the edge of the ignition switch. The ignition switch can be actuated by turning.

  The locking portion may be configured to lock the lighter body when the lighter is mounted and to restrict the movement of the lighter body during the ignition operation. For example, a recess is provided on the side surface of the lighter body, and the recess is engaged with the recess. It can also be set as a locking claw that can be stopped, or can be provided with a surface on which the bottom surface of the lighter body is placed.

  The ignition operation assisting means is disposed above the lighter ignition switch when the lighter is mounted, and the base end is rotatably attached to the upper end of the ignition hole side when the lighter is mounted on the frame via a mounting shaft. The other end has a length that protrudes from the end of the ignition switch as a free end, and any other member that can rotate the ignition switch to actuate the ignition switch, such as a plate shape or a rod shape, is considered. However, the shape is not limited to these.

  According to this device, a frame having a substantially U-shaped cross section and having an open surface on which a lighter is inserted and a locking portion for locking the lighter body is disposed above the ignition switch when the lighter is mounted. An ignition operation assisting means for assisting the switch operation is attached. The ignition operation assisting means is attached to the upper end of the ignition hole side at the time of attaching the lighter of the frame so as to be rotatable through an attachment shaft, and the other end is a free end It is assumed that the length is projected from the edge of the ignition switch, and the ignition switch can be operated by rotating this, so the free end side of the ignition operation auxiliary means is pushed down with the lighter attached. When the is rotated, a force is applied to the ignition switch between the pressing portion and the mounting shaft. In other words, since it is possible to configure an operating point where an operating force is applied to the ignition switch between the pressing portion serving as the power point and the mounting shaft serving as the fulcrum, the second type lever is used to directly operate the ignition switch. You can operate this with less force than you do.

  According to the second aspect of the present invention, since the lighter bottom surface is provided on the locking portion, when the lighter is mounted and the ignition operation assisting means is rotated, the ignition switch The downward force applied to the lighter in accordance with the operation can be stably received by the lighter mounting surface of the locking portion, and the operating force can be applied to the ignition switch in a more stable state.

FIG. 1 is a diagram showing an outline of a lighter ignition operation assisting tool used in a first embodiment of the present invention, that is, mounted on a push button type cigarette lighter.
The frame 1 of the lighter ignition operation assisting tool has a substantially U-shaped cross section having a height substantially the same as the height of the lighter body part so that the body part (fuel container part) below the ignition switch of the attached lighter can be inserted. It is formed in a shape and has an open surface 11 into which a lighter is inserted.
A locking portion 2 for locking the lighter is provided at the lower end of the frame 1. The locking portion 2 includes a substantially flat elliptical mounting surface 21 on which the bottom surface of the lighter is mounted. From the mounting surface 21, a guard 22 having a substantially U-shaped cross section that restrains the movement of the lighter in the horizontal direction. Is formed to stand up.
Also, the open surface 11 side of the upper end of the frame 1 is slightly extended upward, and the extension operation parts 12 and 12 cover the upper end of the frame 1 via the attachment shafts 3 and 3 so as to cover the ignition operation. The ignition operation assisting piece 4 is rotatably attached.
The ignition operation assisting piece 4 is a piece that protrudes from the end of the lighter that is mounted on the side opposite to the ignition hole side of the ignition switch and that has a larger surface than the upper surface of the ignition switch.
The frame 1, the locking portion 2, the mounting shaft 3, and the ignition operation assisting piece 4 are all made of a hard synthetic resin.

FIGS. 2A and 2B are diagrams showing a use state of the lighter ignition operation assisting tool of the present invention, in which FIG. 2A shows a mounted state of a push button type cigarette lighter, and FIG. 2B shows an ignition operation state. It is.
The push button type cigarette lighter L is inserted into the frame 1 from the opening surface 11 so that the ignition switch S side becomes the frame 1 side, and the lower part of the lighter L is placed in the guard 22 of the locking portion 2. It is mounted on the mounting surface 21. At this time, the body B of the lighter L is fitted and inserted into the frame 1 along the inner surface of the frame 1 so that the upper end of the frame 1 is substantially the same height as the upper end of the body part B.
The ignition operation assisting piece 4 rotatably attached to the extending portion 12 of the frame 1 via the attachment shafts 3 and 3 is positioned above the ignition switch S.
When the lighter L is attached to the lighter L, the ignition operation auxiliary piece 4 has a size such that its free end protrudes beyond the edge of the ignition switch S, and is slightly closer to the ignition hole side than the center of the back of the ignition operation auxiliary piece 4. Convex ridges 41 are provided as contact portions that contact the upper surface of S. In addition, this ridge can also be abbreviate | omitted. That is, when the ignition operation assisting piece 4 is rotated, any part of the back surface of the ignition operation assisting piece 4 may abut on the upper surface of the ignition switch S so that the ignition operation can be performed. It is not necessary to be formed as a ridge.

When performing the ignition operation, the free end side of the ignition operation assisting piece 4 is pushed down. Then, the ignition operation assisting piece 4 is rotated about the mounting shaft 3 as the rotation shaft, and the ignition switch S is pushed downward. At this time, since the lower part of the lighter L is restrained by the locking part 2, the bottom surface of the lighter L is pressed against the mounting surface 21 of the locking part 2, and the downward force applied to the ignition switch S escapes. And the lighter L will not come off the frame 1.
Then, the pressing portion on the free end side of the ignition operation assisting piece 4 is a force point, and the mounting shaft 3 serving as the rotation axis of the ignition operation assisting piece 4 is a fulcrum, and between the pressing portion (force point) and the mounting shaft 3 (fulcrum). Since the operating force is applied to the ignition switch S in the protruding ridge 41 which is a contact portion, the second type leverage principle works, and the force is smaller than when the ignition switch S of the lighter L is directly operated. This can be manipulated.
On the other hand, when the lighter is not used, the child resistance can be made to function effectively by removing the lighter ignition operation assisting tool from the lighter.

FIG. 3 is a diagram showing an outline of a lighter ignition operation assisting tool used by being mounted on a sliding cigarette lighter L according to a second embodiment of the invention.
In the lighter ignition operation assisting tool for the slide type cigarette lighter, the upper shape of the frame 1 is made to match the slide range of the slide type ignition switch S, and a ridge is formed on the back side of the ignition operation auxiliary piece 4. The configuration is almost the same as that of the first embodiment except for the absence.
That is, the slide-type cigarette lighter L is operated by sliding the ignition switch S along the upper edge of the body B that draws an arc toward the lower side opposite to the ignition hole. It is necessary to secure a space for sliding S. Therefore, the upper edge of the frame 1 is positioned below the position where the lowermost part of the ignition switch S comes when the ignition switch S is completely slid. For this reason, in this embodiment, the extending portion 12 on the open surface 11 side at the upper end of the frame 1 is greatly extended upward.
Further, since the back side of the ignition operation auxiliary piece 4 is formed as a flat surface so as to be in surface contact with the upper surface of the ignition switch S, the contact portion between the upper surface of the ignition switch and the back surface of the ignition operation auxiliary piece in this embodiment is It is configured as a contact surface.

4A and 4B are diagrams showing a use state of a lighter ignition operation assisting tool for a sliding-type cigarette lighter, in which FIG. 4A shows a mounted state of the lighter and FIG. 4B shows an ignition operation state. is there.
The method of attaching the lighter L to the frame 1 is the same as that of the first embodiment, and when the lighter is attached, the ignition operation auxiliary piece 4 is formed so that the free end side protrudes from the operation direction side edge of the ignition switch S. This is similar to the first embodiment.

When the free end side of the ignition operation assisting piece 4 is pressed with the lighter L mounted, the ignition operation assisting piece 4 rotates about the mounting shaft 3 as a rotation axis, and accordingly, the ignition operation assisting configured with a flat surface. The back surface of the piece 4 can be brought into contact with the upper surface of the ignition switch S so that the ignition switch S can be slid obliquely downward. At this time, since the lower part of the lighter L is restrained by the locking part 2, the downward force applied to the ignition switch S does not escape and the lighter L does not come off the frame 1.
The ignition switch S at the contact portion 41 located between the pressing portion (power point) and the mounting shaft 3 (fulcrum) with the pressing portion on the open end side of the ignition operation assisting piece 4 as the power point and the mounting shaft 3 as the fulcrum. Since the operating force is applied to the second type, this principle works, and this can be operated with a smaller force than when the ignition switch S of the lighter L is directly operated.

FIG. 5 is a view showing an embodiment in which the locking portion 2 has another mode.
That is, it is not essential that the locking portion 2 has a mounting surface as in the above embodiment. A horizontal groove M is provided in the body B of the lighter L, and the inward direction that can be fitted into the groove M is provided. The locking portion 2 is configured by forming a convex portion 23 at the bottom of the frame 1. Other configurations are the same as those of the first embodiment.
When performing the ignition operation of the lighter using this embodiment, when the ignition switch S is pushed downward by pressing the free end side of the ignition operation assisting piece 4, the lighter L receives a downward force via the ignition switch S. In addition, since the lighter L is pressed against the locking projection 23 fitted in the groove M, the downward force applied to the ignition switch S does not escape or the lighter L does not come off the frame 1. .

  The present invention relates to a lighter ignition operation assisting tool that can improve the operability by assisting the operation of the ignition switch when a lighter having a push-in type or a slide type switch is properly used. It has the availability of.
