BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ignition device known as an ignition rod for emitting a gas flame from a front end flame port of a flame port rod extending from a main body section by an ignition operation of the main body section, and particularly to a structure for changing the direction of the flame port. It is about. Background art

Conventionally, a flame port rod is extended from a main body provided with a gas tank for storing liquefied gas of fuel, and a gas flame is blown out from a flame port provided at a distal end of a tip pipe constituting the flame port rod. In addition, ignition devices in which the distance between the ignition position and the ignition operation position is increased so that ignition can be easily performed are commercially available and widely used.

Then, a part of the tip pipe in the flame port rod portion is formed of a flexible member so that the direction of the flame port can be changed, and the tip pipe can be inserted into the bent portion to ignite. A gas igniter which can be used has been proposed (for example, Japanese Patent Application Laid-Open No. 9-133359).

By the way, in the above-mentioned igniting device, since the end pipe of the flame port portion is formed of a flexible member such as a spring, the igniting device changes its shape by contacting the wall of the insertion path or the like. If there is no wall to hit and it is difficult to hold the main unit in the first insertion direction, there is a difficulty in operability.

In other words, in the case of a conventional igniting device in which the flame port of the igniting device is rigid and linearly connected to the main body, the ignition operation through the igniting port of the gas appliance, etc., will result in an unreasonable operating posture. In some cases, it becomes difficult to ignite, or there is a wall or other obstacle on the straight extension of the igniter, so that the tip cannot be inserted into the proper igniting position and good ignitability cannot be obtained. In view of such a point, as disclosed in Japanese Patent Application Laid-Open No. 9-1333359, when the end pipe of the flame outlet rod portion is made of a flexible member, the end portion is formed on the wall surface such as the ignition port. The tip pipe deforms along the insertion path upon contact, and can be inserted at the ignition point. If there is no contact wall as shown in the figure, there is a point where the ignition point cannot be approached without deforming in the direction of the ignition point, and there is a problem that the tip rubs against the wall surface and dirt adheres to it, reducing ignitability. .

In view of the above circumstances, it is an object of the present invention to provide an igniting device that can change the direction of the flame port rod with respect to the main body and is directed toward an ignition point to improve ignitability. It is. Disclosure of the invention

The ignition device of the present invention comprises: a main body having a gas tank for storing a liquefied gas serving as fuel; and a flame port rod portion extending in a rod shape from the main body and having a flame port at a tip for emitting a gas flame. In the igniter, the main body portion includes a plurality of holding portions pointing in different directions, and the holding portion selectively holds the flame port rod portion to change the direction of the flame port. Is what you do.

The main body preferably includes a connection groove that connects the holding portion and allows movement of a gas pipe connected to the flame mouth bar when changing a holding position of the flame mouth bar. is there.

It is preferable that the gas pipe be provided flexibly and deformably and freely.

It is characterized in that it has an urging member for urging the burner port portion in the direction of insertion and holding into the holding portion.

The main body portion includes a plurality of holding portions communicating with each other and pointing in different directions, and the flame outlet rod portion slides on the holding portion and is engaged and held by the holding portions in different directions to hold the flame outlet. The direction may be changed.

According to the ignition device of the present invention as described above, a flame port having a flame port at a tip end is selectively held by a plurality of holding sections of a main body section provided with a gas tank which are directed in different directions. The direction of the flame stick can be changed, so the flame stick can be easily inserted into complicated wall angles and gaps, and the hand holding the main body rubs against the wall. It can be operated by holding the main body at an easy-to-hold angle without causing any trouble, and good ignition can be performed by bringing the tip flame close to the ignition point. In addition, when a product with a long overall length is held in a state where the flame stick is pulled out from the main body or is greatly bent, it is possible to shorten the overall length and make it compact. It is easy to store and carry.

Since the direction of the flame port can be changed separately from the main body, the gas flame can be prevented from hitting the finger, hand, or the main body to be operated when ignited. Brief Description of Drawings
