  The conventional portable gas burner is premised on being used with a finger. For this reason, it is necessary to fix the object to be heated or hold the gas burner with one finger and hold the object to be heated with the other finger to perform the heating operation.

  However, many objects to be heated using a small gas burner have small dimensions. For this reason, it may be difficult to fix depending on the form of the object to be heated. In addition, a special fixing tool for fixing the object to be heated is often required. And when heating a wide range, the fixed location of a to-be-heated object may need to be changed during a work.

  Although it is conceivable to hold the object to be heated with one finger and operate the gas burner with the other finger, it is difficult to perform precise heating.

  In order to avoid the inconvenience, it is conceivable to fix the gas burner on a desk or the like. However, if the direction of the flame is fixed, there is a risk that the usability will worsen. Moreover, since the portable small gas burner is small in size, an instrument of a certain size is required to stably install it on the desk, which impedes portability. In some cases, it is better to use the gas burner in a handheld state.

  Furthermore, when the flame of the gas burner installed on the desk is ejected toward the wall or the desk, there is a risk of scorching these members or causing a fire. For this reason, it is necessary to comprise so that it can install in a certain area with respect to an installation surface. However, if a stand or the like having a large area in contact with the installation surface is provided, portability is greatly hindered.

  The present invention solves the above-mentioned conventional problems, can be installed and used in a state of ensuring safety on a desk or the like, and can also be used in a handheld state without impairing portability. The objective is to provide a gas burner with improved performance.

  A gas burner according to the present invention is connected to the gas burner main body having a head portion provided with a combustion nozzle, a tank for storing fuel gas, and a gripping portion for gripping with fingers, and the nozzle. And a holding stand that can be installed by adjusting the jet direction of the flame jetted from within a predetermined range.

Moreover, the present invention is configured to include a holding stand that can be installed by adjusting the jet direction of the flame jetted from the nozzle within a predetermined range. By providing the holding stand, it can be used even when installed on a desk or the like.

  It can be used on hand or installed on a desk, etc., so that the range of applicable objects to be heated can be expanded, and it can be heated by an optimal method according to the form of the object to be heated. Become.

  Moreover, by adjusting the flame ejection direction, it is possible to adjust the flame direction according to the work posture of the worker and the form of the object to be heated. For this reason, while being applicable to a to-be-heated object of a various form, a heating operation can be performed easily. In addition, since the worker can perform the work while holding the object to be heated with both hands, the efficiency and accuracy of the work can also be improved.

  The configuration of the holding stand is not particularly limited. For example, it can comprise and comprise the arm part connected with the said gas burner main body so that rotation is possible, and the base part for installing in an installation surface.

  In the gas burner according to the present invention, the holding stand is provided so that the gas burner can be installed and used on a setting surface such as a desk. On the other hand, the holding stand requires a certain contact area so that the gas burner main body can be securely held, and also requires strength. For this reason, there is a possibility that the holding stand may become an obstacle when the gripping part is gripped and used. In order to avoid this inconvenience, in the present invention, when the gas burner is used by hand, the holding stand is configured to be able to take a retracted position retracted from the vicinity of the gripping portion.

  For example, the holding stand is configured to include a connecting member that can position and hold the gas burner main body within a predetermined angle range with respect to the installation surface, and the retracted position retracted from the vicinity of the gripping portion can be taken. Can be configured.

  The method for taking the retracted position is not particularly limited. It is only necessary that the holding stand can be separated from the gripping portion in a state where the holding stand is attached to the gas burner body. For example, a holding stand is rotatably connected to the gas burner body, and when gripping the gripping part, the holding stand is rotated backward or upward of the head part to grip the gripping part. It is desirable to configure so as not to obstruct the fingers.

  The configuration of the holding stand is not particularly limited as long as the gas burner main body can be stably held via the connecting member. For example, the holding stand can be configured by including a base portion that is in contact with the installation surface and an arm portion that is erected on the base portion. The holding stand includes a pair of arm portions that extend in parallel along both sides of the gripping portion, and a base portion that stands on the installation surface and can be installed on the installation surface. Via the connecting member provided at the tip, the head portion or the vicinity thereof can be configured so as to be rotatable around a shaft parallel to the installation surface within a predetermined angle range.

  The arm portion can be composed of a pair of members extending in parallel so as to sandwich the gas burner body. By positioning and holding the gas burner main body within a predetermined rotation range via the connecting member provided at the tip of the arm portion, the flame can be ejected in a required direction.

  The configuration of the connecting member is not particularly limited. For example, the gas burner body side and the holding stand side are provided with a pair of connecting members that can rotate relative to each other and can be positioned at a required relative angular position, and by adjusting the rotation angle between these connecting members, the flame can be directed in the required direction. Can be spouted toward The mechanism for positioning and holding at the required relative angular position is not particularly limited, and for example, a thumbscrew that can easily tighten the pair of connecting members at the required relative angular position can be employed. In addition, a positioning mechanism that can be stepwise locked at a predetermined angular interval between the pair of connecting members can be employed. For example, it is configured so that the joint members that engage with each other are provided between the connecting members, and the connecting members are elastically biased by a spring member so as to be movable in the axial direction, so that the engaging position of the seat members can be changed. be able to.

  The base portion is configured to have a required ground contact area so as to stably support the gas burner body within the set rotation range via the arm portion. Thereby, it becomes possible to hold | maintain safely the gas burner which injects a flame toward a required direction.

  The flame of a gas burner is stronger than ordinary gas lighters and has a high temperature. For this reason, when a flame is jetted close to the installation surface, the installation surface may be burnt or a fire may be caused. In order to ensure safety, it is desirable to configure the holding stand so that the tip of the combustion nozzle from which the flame is ejected can be regulated and held so as not to be close to the installation surface. For example, it is desirable to configure the flame ejection direction with respect to the installation surface so as not to exceed a predetermined angle. Further, it is desirable that the combustion nozzle is provided at a predetermined distance from the installation surface. Specifically, the connecting member is injected by adjusting the angle of the flame ejected from the combustion nozzle within an angle range from a direction heading at 45 degrees to the installation surface to a direction perpendicular to the installation surface. It is preferable to be able to configure. When the flame ejection direction (angle between the installation surface and the flame ejection direction) with respect to the installation surface is 45 degrees or more, the heat of the flame is easily transmitted to the installation surface, and the temperature of the installation surface is likely to rise. Moreover, it becomes difficult to ensure the space for positioning a to-be-heated object between installation surfaces. Furthermore, in order to ensure safety, the holding stand is preferably configured so that the tip of the combustion nozzle is separated from the installation surface by 6 cm or more. Thereby, it becomes difficult for the heat of a flame to be transmitted to an installation surface, and safety | security increases.

  The holding stand can be detachably connected to the gas burner body or can be detachably connected. In order to detachably hold the gas burner body, a connecting member including a holding member that detachably holds the gas burner body may be employed.

  The structure of the holding member is not particularly limited. For example, the gas burner gripping portion can be accommodated and held. Moreover, you may provide the holding structure which can be attached to the said holding | grip part and the said holding member so that attachment or detachment is possible. By holding the gas burner detachably on the holding stand, it is possible to perform work by injecting a flame in a required direction in the installed state, and to remove the gas burner main body from the holding member and perform the work in a handheld state. This makes it possible to improve workability.

  It is preferable to provide a mounting magnet on the base portion so that the gas burner can be used by being adsorbed to a magnetic material such as an iron plate. For example, simply installing on a desk may cause the gas burner to fall over when an object to be heated or a foreign object comes into contact. For this reason, it is preferable that an iron plate having a larger area than the base portion is laid on the desk, and the mounting magnet is adsorbed for use. Furthermore, the safety is further enhanced by setting the fired flame to face the iron plate.

  In order to prevent the holding stand from overturning, it is preferable that an extension portion for preventing overturning is provided in the base portion. For example, an extending piece that extends radially outward from the peripheral edge of the base portion along the installation surface can be provided as the extending portion.

  Furthermore, the extension portion can be provided so as to protrude from the edge portion of the base portion. For example, a disc-shaped base portion can be provided, and an extending piece that protrudes and protrudes from the base portion in a predetermined direction can be provided.

  The gas burner can be installed and used in a state where safety is ensured on an installation surface such as a desk, and can also be used in a hand-held state without impairing portability.
