Abstract

An object of the present invention is to provide an attachment that can easily attach an object to be supported (air hose of a spray gun) to a support (an operator's arm). A fixture includes a band portion, a fixed head portion, and a movable head portion. The fixed head portion 18 has a first through hole 24 that is inserted through the tip end portion 16 b after the band portion is bent so as to form the first annular portion R <b> 1 along the periphery of the air hose 14. The movable head portion 20 is bent so that the second through-hole 34 through which the band portion is inserted from the tip portion and the second annular portion R2 along the circumference of the arm N are formed by the band portion drawn out from the second through-hole. The third through hole 36 is inserted through the tip after being formed. Furthermore, the movable head portion has a first lock portion 40 that prevents the band portion from moving in the direction opposite to the insertion direction in the third through hole.

Description

  The present invention relates to a fixture for attaching a support object to a support portion.

  FIG. 10 is a front view showing a use state of a general spray gun 1. The spray gun 1 sprays the paint W toward the object to be painted (not shown), and an air hose 2 for supplying compressed air is connected to the spray gun 1. When the object to be painted is painted using the spray gun 1, the weight of the air hose 2 directly acts on the hand M of the operator X. Further, when the spray gun 1 is brought close to the object to be coated, there is a possibility that the air hose 2 may come into contact with the object to be painted, so that there is a problem that the handling of the spray gun 1 is not good. Therefore, the operator X may have the air hose 2 with a hand opposite to the hand M holding the spray gun 1 (see FIG. 2 of Patent Document 1). However, in this case, there is a problem that workability is not good because it is impossible to hold the object to be painted with the hand or change the direction of the object to be painted.

Japanese Patent No. 5807278

  As a result of intensive studies to solve these problems, the inventor of the present application has conceived that the air hose 2 is supported by the arm N on the side having the spray gun 1 of the operator X. If the air hose 2 is supported by the arm N, the load on the air hose 2 acting on the hand M can be reduced, so that the fatigue of the hand M can be reduced. Further, since the air hose 2 can be supported at a position away from the spray gun 1, the handling of the spray gun 1 is improved. Further, the object to be painted can be held with the hand opposite to the hand M holding the spray gun 1 or the direction of the object to be painted can be changed. However, it is not easy to attach the air hose 2 to the arm N using an existing fixture such as a string because a work for tying is required.

  The present invention has been made to solve the above problems, and provides an attachment that can easily attach a support object (for example, an air hose) to a support portion (for example, an arm of an operator). Objective.

  In order to achieve the above object, a feature of the fixture according to the present invention is a fixture for attaching a support object to a support portion, which is an elongated linear band portion having flexibility, and A fixed head portion provided at a base end portion, and a movable head portion provided between the base end portion and the distal end portion of the band portion so as to be position-adjustable in the length direction of the band portion, and The head portion has a first through hole that is inserted from the tip after the band portion is bent so as to form a first annular portion along one circumference of the support object and the support portion. And the movable head portion includes the second through-hole through which the band portion drawn out from the first through-hole is inserted from the tip portion, and the band portion drawn out from the second through-hole is the object to be supported. Along the other periphery of the object and the support A third through hole that is bent so as to form two annular portions and then inserted from the tip thereof, and a first that prevents the band portion from moving in a direction opposite to the insertion direction in the third through hole. And having a lock portion.

  In this configuration, when attaching the support object to the support part, it is only necessary to pass the tip of the band part through the first through hole, the second through hole, and the third through hole in order, so that the support object is supported. Can be easily attached to the part.

  Another feature of the present invention is that a plurality of hook portions are continuously formed in the length direction on the surface of the band portion, and the first lock portion is connected to any one of the plurality of hook portions. It has in having the 1st lock claw caught.

  In this configuration, the effective length of the band portion can be finely adjusted according to the size of the support object and the support portion by selecting the catch portion where the first lock claw is caught.

  In another feature of the present invention, the fixed head portion includes a second lock portion that prevents the band portion from moving in a direction opposite to the insertion direction in the first through hole. The lock portion has a second lock claw that is hooked on any of the plurality of hook portions.

  In this configuration, since the band portion can be prevented from moving in the direction opposite to the insertion direction in the first through hole by the second lock portion, the band portion is loosened to one outer surface of the support object and the support portion. It can be closely attached. Thereby, it can prevent that the position of a band part shifts to one of a support subject and a support part.

  Another feature of the present invention is that the movable head portion includes a third lock portion that prevents the band portion from moving in a direction opposite to the insertion direction in the second through hole. The lock portion has a third lock claw that is hooked on any of the plurality of hook portions.

  In this configuration, since the band portion can be prevented from moving in the direction opposite to the insertion direction in the second through hole by the third lock portion, the band portion is loosened to the other outer surface of the support object and the support portion. It can be closely attached. Thereby, it can prevent that the position of a band part shifts to the other of a support subject and a support part.

  Another feature of the present invention is that the size of the cross section of the second through hole is sufficiently larger than the size of the cross section of the band portion so as to allow the band portion to move in the insertion direction and the opposite direction. It is to have been enlarged.

  In this configuration, in the second through hole, movement of the band portion in the insertion direction and the opposite direction is allowed, so that it is possible to suppress overtightening the portion constituting the second annular portion of the band portion, and The diameter of the two annular portions can be easily enlarged.

  Another feature of the present invention is that the size of the cross section of the first through hole is sufficiently larger than the size of the cross section of the band portion to allow the band portion to move in the insertion direction and the opposite direction. It is to have been enlarged.

  In this configuration, in the first through-hole, movement of the band portion in the insertion direction and the opposite direction is allowed, so that it is possible to suppress overtightening the portion constituting the first annular portion of the band portion, and The diameter of one annular part can be expanded easily.

  Another feature of the present invention is that the object to be supported is an air hose for supplying compressed air to the spray gun, and the support portion is an arm of an operator who operates the spray gun.

  In this configuration, since the air hose can be supported by the operator's arm, the load of the air hose acting on the operator's hand can be reduced and hand fatigue can be reduced. Further, since the air hose can be supported at a position away from the spray gun, the handling of the spray gun can be improved.
