Abstract

PROBLEM TO BE SOLVED: To improve the operability by arranging a cover having a flat periphery and for covering a duct hose freely to be removed. SOLUTION: A cylindrical cover 5 having flat periphery and formed of the nylon woven fiber having excellent abrasion resistance and tearing resistance is arranged freely to be removed so as to cover a duct hose 3 having rugged parts in the periphery thereof. A space for insertion of a power source cord 6 is provided between the outer peripheral part of the duct hose 3 and the inner peripheral part of the cover 5. Since the duct hose 3 covered with the cover 5 has flat peripheral surface without hindering the bending performance thereof, a trouble that the peripheral rugged surface of a duct hose 3 is hooked on an end surface corner of a material 4 to be cut is eliminated, and cutting work is smoothened. Hindrance of the work by the power source cord 6 is eliminated by inserting the power source cord 6 electrically connected to a power source supply unit of a duct collecting device into the duct hose 3, and workability and operability are improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering the outer periphery of a duct hose having irregularities connected to a hand-held power tool and a dust collector.

[0002]

2. Description of the Related Art A duct hose 23 connected to a hand-held power tool 21 and a dust collector 22 will be described with reference to FIGS. FIG. 3 shows a circular saw 21 which is a hand-held power tool 21 connected to a duct hose 23 of a dust collector 22 to cut the work material 24 while collecting cutting dust generated when cutting the work material 24. In this case, the duct hose 23 used in such an application is lightweight and has excellent flexibility so as not to lower the operability of the connected electric tool 21. Such a duct hose 23 is formed of a thin soft vinyl chloride material or the like as shown in FIG. 4 and is formed by winding a reinforcing body portion such as a hard vinyl chloride material around the outer peripheral surface of a cylindrical body in a spiral shape. 5 and those formed in a concavo-convex shape with a thin soft vinyl chloride material or the like as shown in FIG. 5, and the outer peripheral surface of each of the duct hoses 23 has a concavo-convex shape. For this reason, when the work of cutting the work material 24 is performed by connecting the duct hose 23 having the above configuration to the circular saw 21, as shown in FIGS. There has been a problem that it becomes difficult to perform the cutting operation with the circular saw 21 smoothly because the edge saw is caught at the corner of the end face. Therefore, in order to solve the above problem, it is conceivable to use a duct hose having no irregularities on the outer peripheral portion and the inner peripheral portion, but it is difficult to catch, but the thickness of the hose is reduced to withstand the suction pressure of the dust collector 22. However, this method is not suitable for the dust collecting duct hose 23 because the bending property is deteriorated and the weight becomes heavy. Furthermore, the duct hose having a flat outer peripheral portion and irregularities formed on the inner peripheral portion has good flexibility and light weight, but on the other hand, there is a problem that dust easily accumulates on the irregularities in the duct hose. It was not suitable for the duct hose 23 for dust collection.

[0003] Further, since a power tool such as the circular saw 21 has a power cord 25, the duct hose 23 and the power cord 25 are connected to the power tool. For the operator performing the cutting work, the uncomfortable duct hose 23 and the power cord 25 feel cumbersome, leading to a reduction in workability.

[0004]

The duct hose of the dust collector connected to the hand-held power tool does not reduce the operability of the power tool, so it is lightweight, has excellent flexibility and is not crushed by the suction force of the dust collector. A duct hose with a flat inner surface is used. In order to satisfy such performance, the outer surface of the duct hose is generally formed with irregularities, and the irregularities are caught on the work material, and consequently the operability of the power tool is reduced. Had the problem of doing so.

A power cord and a duct hose are connected to the power tool. If the power tool is operated in this state, the power cord and the duct hose move separately. Has caused inconvenience, leading to a decrease in workability and operability.

[0006] An object of the present invention is to solve the above-mentioned problems and to provide a dust collector excellent in operability.

[0007]

An object of the present invention is to provide a dust collector having a power supply unit, a power tool having a power cord electrically connected to the power supply unit, and connecting the power tool and the dust collector. In a dust collector provided with a duct hose, this is achieved by removably arranging a flat outer peripheral cover that covers the duct hose.

[0008] The cover is achieved by being formed of a woven nylon fabric.

[0009] It is further achieved by providing a space for inserting the power cord between the duct hose and the cover.

[0010]

1 and 2 show an embodiment of the present invention.
This will be described with reference to FIG. FIG. 2 shows a work in which a duct hose 3 of a dust collector 2 is connected to a circular saw 1 which is a hand-held power tool, and a cutting dust generated during a cutting operation is sucked by the dust collector 2 while cutting a work material 4 by the circular saw 1. The state is shown. The duct hose 3 has irregularities on its outer periphery, and has a cylindrical and flat outer peripheral cover 5 formed of nylon woven cloth or the like having excellent wear resistance and tear resistance so as to cover the duct hose 3. Is arranged. A space is provided between the outer periphery of the duct hose 3 and the inner periphery of the cover 5 so that the power cord 6 of the circular saw 1 can be inserted. A string 7 for fixing the cover 5 to the duct hose 3 is sewn to both ends of the cylindrical shape of the cover 5, and a magic tape (registered trademark) is sewn to the string 7 so that the cover 5 is attached to the duct hose 3. It can be fixed detachably. The power cord 6 of the circular saw 1 is inserted into the inner diameter hole of the cover 5 before connecting the duct hose 3 to the dust collector 2 or the circular saw 1. Duct hose 3 covered with such a cover 5
Is a cutting operation using the circular saw 21 because the outer peripheral surface of the duct hose 3 does not catch on the corners of the end surface of the work material 4 during the operation because the outer peripheral surface is flat without impairing the flexibility. Can be obtained smoothly.

Further, by inserting the power cord 6 of the circular saw 1 electrically connected to the power supply unit of the dust collector 2 into the duct hose 3, the power cord 6 of the circular saw 1 becomes an obstacle during work. The workability and operability can be further improved.

[0012]

According to the present invention, the operability of the dust collector can be improved by arranging a cover having a flat outer periphery on the outer periphery of the duct hose in a detachable manner.
