Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighter flame adjustment device for adjusting the flame size of a gas lighter.

Generally, in a gas lighter, an elastic porous material is housed in the gas ejection flow path, and this is pressed by an adjustment rod that is moved back and forth by rotational operation from the outside, causing the gas to permeate through the porous material. The flame is controlled by adjusting the amount of gas.

This adjustment rod is often operated at the bottom of the lighter, and in order to improve its operability, the adjustment rod connected to the adjustment rod is usually made to protrude from the bottom of the lighter. It is already known that the device is housed in an exterior case and protrudes outward during operation (for example, Utility Model Publication No. 43-5342, Utility Model Publication No. 42-8823, and Utility Model Application Publication No. 52-124865). .

However, this type of device has a complicated interlocking structure for the adjustment rod that moves in and out, and not only requires a large number of parts but also requires a lot of effort to assemble, resulting in high costs. there were.

In addition, when adjusting this kind of flame, it is undesirable to perform unlimited shooting operations due to safety issues during use or mechanical safety. First, it is necessary to restrict the porous material for gas permeation amount adjustment to a range in which it is not compressed more than necessary, and the restriction range needs to be adjustable by the user.

As a mechanism for this purpose, for example,
Although there are regulations, the structure is generally complex or it is difficult to change the scope of regulation.

Further, in all of the conventional devices described above, the shooting operation section is exposed outside the case, so it may move when being carried.

In view of the above-mentioned conventional problems, the present invention has a flame adjustment mechanism that can be protruded during operation, and the assembly structure of the flame adjustment mechanism is simple, the number of parts is small, and assembly is easy. Moreover, it has the same structure as that for regulating the range that can be operated by shooting, and the number of parts is reduced.
The purpose of the present invention is to provide a flame adjustment device for a lighter, which allows the user to easily change the regulation range, and which is safe because the flame is normally housed in the lid and does not move when carried. The gist of this is that a lighter body with a gas tank is housed in an outer case, and a gas ejection amount adjustment device is provided that can be moved in and out from one side of the outer case. In a flame adjustment device for a lighter that can be operated by protruding outward, a gas ejection amount adjustment rod is provided inside a fixed lid of an exterior case from one side of the lighter body, and the gas ejection amount adjustment rod is rotated to adjust the gas ejection amount. A blind hole is provided on the protruding end surface of the adjustment rod, and a stopper ring in the shape of a cylinder with a bottom is supported on the outer peripheral surface of the adjustment rod so as to be non-rotatable and to change the relative angle. A gas ejection amount adjusting device whose tip can be accommodated in the blind hole is supported in the center of the stopper ring so as to be slidable in the axial direction and non-rotatable in the circumferential direction, and the fixed lid has the A flame regulating device for a gas lighter is characterized in that it is equipped with an opening/closing lid for opening and closing an entrance/exit of a regulating device.

Next, an example of implementation of the present invention will be described with reference to the drawings.

Reference numeral 1 in the figure is a lighter body housed in an exterior case 8 and integrally equipped with a gas tank and the like.

Reference numeral 3 designates a ring-forming pipe that passes through the lighter body 1 and is equipped with a nozzle (not shown) at its upper end and contains a porous material for adjusting the amount of ejected gas.

A gas ejection amount adjustment rod 2 is inserted into this ring-forming pipe 3 from its lower end.
are inserted and screwed together.

The adjustment rod 2 is rotated to move back and forth within the pipe 3, thereby changing the pressing force against the porous material described above, thereby adjusting the amount of ejected gas.

The lower end of the adjustment rod 2 is located within the fixed lid 8a on the bottom surface of the outer case 8 and protrudes from the bottom surface of the lighter body 1.

A blind hole 21 is formed in the axial direction on the end face of the lower end protrusion, and a large number of axial grooves are formed at regular intervals on the outer peripheral surface of the lower end protrusion by knurling.

The protruding portion at the lower end of this adjustment rod 2 has a groove formed on the inner surface 61 that fits into the groove described above, so that both grooves are fitted into each other, and rotation in the circumferential direction between them is disabled, and the stopper ring 6 is fitted. has been done.

The stopper ring 6 has a stopper protrusion 6a protruding in the radial direction on its outer periphery for regulating the rotation range of the adjustment rod. The rotation range is restricted by coming into contact with the protruding fixed protrusion, and the adjustment restriction range is changed by removing the stopper ring 6 from the adjustment rod 2 and changing the fitting angle between them. I'm trying to make it happen.

Note that the stopper ring 6 is attached to the fixed lid 8a of the outer case 8.
Removal is prevented, and removal is possible by removing the fixed cover 8a.

゛The stopper ring 6 has a cylindrical shape with a bottom, and the adjustment ring 5 is inserted into a square hole 63 formed in the center of the bottom wall 62 so as to be movable in the axial direction and non-rotatable with respect to the stopper 6. ing.

The adjustment lens 5 consists of a flat plate-shaped shaft portion 52 and a photographing portion 51 integrally provided at the lower end thereof in a T-shaped arrangement.The E-ring 7 is fitted into a groove portion 53 formed at the tip of the shaft portion 52. Arrived,
The stopper ring 6 prevents removal.

Further, the upper end of the adjustment camera 5 is accommodated in the blind hole 21 of the adjustment rod 2, and the opening/closing lid 9 provided on the fixed lid 8a is biased by a spring 9a to close the entrance/exit. The photographing section 51 is prevented from being exposed to the outside.

The flame adjustment device constructed in this manner is constructed by either pulling up the opening/closing lid 9 with a nail or the like and lowering the adjustment camera 5 by its own weight, or pulling it out with a nail or the like. By protruding its tip and rotating it, the adjustment rod 2 is rotated together with the stopper ring 6', and the amount of gas ejected is adjusted.

The flame regulating device for a lighter according to the present invention is constructed as described above,
One end of the gas ejection amount adjustment rod is made to protrude from the lighter body, a stopper ring is fitted onto it, an adjustment lens is supported in the center of the stopper ring, and this is inserted into the blind hole on the lower end of the adjustment rod. By making the adjustment stick protrude from the outer case and operate it, it is only necessary to install it on the stopper ring separately from the installation of the adjustment rod into the lighter body. To incorporate the stopper ring, simply fit it to the lower end of the adjustment rod, and the structure for adjustment operation is significantly simpler than before, and the installation of the adjustment ring and the stopper ring are common. As a result, the total number of parts is significantly reduced, and it is also possible to easily perform not only adjustment photography but also the installation of a stopper ring.

Furthermore, since the adjustable camera is normally housed in the opening/closing lid, it will not move unexpectedly when you carry it, making it highly safe.
