FIG. A is a left side view, FIG. B is a plan view, FIG. C is a right side view, and FIG. The figure is a bottom view and the figure f is a rear view. It is explanatory drawing explaining the mounting condition of the dust collection sander apparatus shown in FIG. 1, and the coating | coated member and communication jig | tool shown in FIG.

  In the present invention, a dust collecting sander device comprising a hand-held sander portion that exposes a filed surface for polishing a surface to be polished, and a dust collecting means for sucking dust generated by polishing of the surface to be polished by the hand-held sander portion It is. The file surface may be equipped with a metal file plate, or may be used with sandpaper having a desired fineness adhered to the support plate.

  As the hand-held sander part of the present invention, a filed surface for polishing the surface to be polished may be exposed, and the filed surface may be polished by this filed surface. The polishing may be performed by manually bringing the file surface into contact with the surface to be polished, and if possible, the surface to be polished may be polished with an electrically driven file surface. However, in the case of driving electrically, since the driving power source is a battery and a large battery is required, it is preferable to manually polish the filed surface by contacting the surface to be polished.

  The dust collection means of the present invention includes a cover member that covers the upper surface and / or the periphery of the file surface with the file surface of the handheld sander exposed, a motor unit installed on the cover member, and the motor unit The fan part that rotates by the rotation of the fan part and the dust in the cover member from one or more suction ports that are installed in the cover member so as to surround the fan part and create negative pressure by rotation of the fan part and communicate with the cover member A suction chamber for sucking air containing air and a discharge port for discharging air containing dust sucked in the suction chamber. As a result, the electric dust collector and the dust collecting sander are not separated and integrated, so that handling by the operator is facilitated.

  In addition, as one or more suction ports, the thing formed inside the cover member around the file surface, the thing drilled in the file surface, etc. are pointed out. For example, a file surface made of a metal file includes a suction port formed in the file plate itself, or a suction port formed in a support plate to be attached if sandpaper is attached. The sandpaper includes one in which a suction port is formed in the sandpaper at a position matching the suction port formed in the support plate.

  As the cover member of the present invention, any cover member may be used as long as it covers the upper surface and / or the periphery of the file surface, and does not cause any trouble in the polishing operation. Aspirate the dust in the suction chamber. Further, a breathable member or brush may be provided in the gap.

  In such a dust collecting sander device, the present invention further includes a battery for driving a motor unit built in the handle portion of the handheld sander unit. In other words, by incorporating a relatively heavy battery in the handle portion that the operator has, the center of gravity of the sander device is small even when working on the wall or ceiling, so the operator can easily handle the sander device. It becomes. For this reason, the polishing operation can be easily performed.

  In another device, the cover member may be further covered so as to block the file surface, and one or more suction ports are provided from the inside of the cover member at the tip of the cover member attached to the cover member. A tip suction port that communicates with the suction chamber is formed. Thereby, dust collection work can be performed also in situations other than polishing work. In particular, since the suction port is formed at the tip portion, the dust collection operation can be performed so as to operate a normal handy type vacuum cleaner.

  That is, the cover member is attached to the cover member to form a space communicating with the suction chamber. Since the tip suction port is formed at the tip of the covering member, when the fan member is rotated, the space surrounded by the cover member and the covering member becomes negative pressure, and the outside air from the tip suction port Dust is sucked and concentrated in one or more suction ports in the cover member with a dust bag attached to the discharge port via the suction chamber.

  Furthermore, in another device, further comprising a communication jig attached to the discharge port, and a dust bag for scavenging dust from the air containing the dust discharged through the communication jig, It is fixed so as to be rotatable relative to the discharge port, and has a "<"-shaped passage for the discharge port to the dust bag. Thereby, the position of a dust bag can be changed according to the situation of work.

  Further, in another device, the file surface is a support plate that is a substrate of the handle portion of the handheld sander portion, a sandpaper whose back surface that is latched and held by the support plate is a loop surface of a hook-and-loop fastener, and the sandpaper It consists of hook material of hook-and-loop fastener that holds and holds the loop surface of the paper and the support plate, and the support plate supports a protruding edge with a height smaller than the height position to the bonding surface of the hook-and-loop fastener In the case where it is formed over the entire circumference of the plate, the inflow of air from the side of the periphery of the support plate is limited by the protruding edge, so that the suction of dust generated by sandpaper polishing is more effective. Can be done.

FIG. 5 is an explanatory view for explaining a mounting state of the dust collecting sander device shown in FIG. 1 and the covering member and the communication jig shown in FIG.

  As shown in FIG. 1, the dust collecting sander device 10 of the present embodiment includes a support plate 11 on one side of the sandpaper for exposing the file surface, and a handle 12 on the other side. A hand-held sander unit 13 and a dust collecting means 20 for sucking dust generated by polishing the surface to be polished by the hand-held sander unit 13 are provided. The support plate 11 has a hook-and-loop fastener material 17 that is raised in a hook shape that exposes and hooks the loop surface that is raised and looped densely in a loop shape on the back surface of the sandpaper 16 shown in FIG. Has been issued.

  As the dust collecting means 20, a cover member 21 that covers the periphery of the file surface of the handheld sander portion 13, a motor portion 22 installed at the rear end portion of the handle portion 12 of the cover member 21, and the motor portion 22 rotate. The fan part 23 and the fan part 23 installed on the cover member 21 so as to surround the fan part 23 rotate to create a negative pressure, so that a large number of suction ports 24 and 25 communicated in the cover member 21 are connected to the inside of the cover member 21. A suction chamber 26 for sucking air containing dust and a discharge port 27 for discharging air containing dust sucked in the suction chamber 26. As shown in FIG. 1 e, a screw hole 18 having a relatively large diameter is formed, and the cover member 21 and the passage forming plate 28 are screwed to the support plate 11 through the screw hole 18.

  The suction chamber 26 of the dust collecting sander device 10 of the present embodiment has a cylindrical inner shape that holds the motor unit 22 and the fan unit 23 therein. The motor unit 22 is installed in a cylinder of the cylindrical fan unit 23, and the fan unit 23 is rotated by driving the motor unit 22. A large number of blades are formed around the cylinder of the fan unit 23, and the flow of the outward air is generated by the rotation of the large number of blades, and the air is discharged from the discharge port 27 formed on the cylindrical side surface of the suction chamber 26. Is discharged, and the inside of the suction chamber 26 is set to a negative pressure.

  On the other hand, a large number of suction ports 24 and 25 are formed on the lower surface side of the cover member 21 through the support plate 11. Specifically, the suction ports 24 and 25 are arranged around the support plate 11 and communicated with the periphery of the lower surface of the cover member 21, and the grip portion of the cover member 21 arranged at the center of the support plate 11. There are two types: a round hole suction port 24 that communicates with the lower surface of the passage forming plate 28 that is provided by projecting the cover member 21 upward.

  The air containing dust sucked by the slit suction port 25 is sucked from the periphery of the cover member 21 to the passage forming plate 28 in the center, and the air containing dust from the round hole suction port 24, the passage forming plate 28 and the support plate 11. Are merged in the passage formed by the above and sucked into the suction chamber 26 having a negative pressure. As shown in FIG. 2, the sandpaper 16 bonded to the hook-and-loop fastener material 17 of the support plate 11 is a breathable base material having a back surface in which the bonding surface is raised like a loop. Air containing dust passing through the material is sucked into the round hole suction port 24 and the slit suction port 25 which are not blocked by the hook-and-loop fastener material 17.

  Further, as shown in the enlarged view of FIG. 2, the support plate 11 has a protruding edge portion 19 having a height smaller than the height position to the bonding surface of the hook-and-loop fastener material 17 over the entire circumference of the support plate 11. Is formed. Since the inflow of air from the peripheral side of the support plate 11 is restricted by the protruding edge 19, the dust generated by polishing with the sandpaper 16 is more sucked into the round hole suction port 24 and the slit suction port 25. Can be done effectively.

  As shown in FIG. 3, in the dust collecting sander device 10 of the present embodiment, a battery for driving the motor unit 22 is built in the handle unit 12 of the handheld sander unit 13. In other words, a handle cover 14 is detachably attached to the handle portion 12, and a battery holder 15 capable of holding a dry battery is disposed therein. By attaching a battery to the battery holder 15 and attaching the handle cover 14, a relatively heavy battery is built in the handle portion 12 that is held by the operator, so that even when working on the wall or ceiling, Since there is little change in the center of gravity of the dust sander device 10, the operator can easily handle the dust collector sander device 10. For this reason, the polishing operation can be easily performed.

  The battery can be held inside the handle portion 12 without being attached to the battery holder 15, and may be a rechargeable battery that conforms to the shape of the handle portion 12 instead of the cylindrical shape. Thereby, since the change in the center of gravity of the dust collecting sander device 10 is small even in the work on the wall and ceiling, the operator can easily handle the dust collecting sander device 10.

  The dust collection sander device 10 of the present embodiment can perform a dust collection operation so as to operate a handy type vacuum cleaner. As shown in FIG. 4, the covering member 30 of the present embodiment is mounted so as to cover the file surface of the dust collecting sander device 10 shown in FIG. The covering member 30 has a peripheral edge portion 31 rising and has a dish-like appearance, and the cover member 21 of the dust collecting sander device 10 can be fitted therein. A hooking piece 32 for hooking on the cover member 21 when fitted is formed at substantially the center of the four vertical and horizontal edges of the peripheral edge 31.

  The covering member 30 has a tip suction port 33 formed at a tip portion attached to the cover member 21 and communicates from the inside of the cover member 21 to the suction chamber 26 through the suction port. In this embodiment, as shown in FIG. 4e, the slit suction port 25a at the position closest to the tip suction port 33 of the cover member 21 is excluded from the numerous suction ports 24 and 25 drilled in the support plate 11. A round projecting piece 34 and a slit projecting piece 35 are formed so as to block all the suction ports 24 and 25.

  That is, a negative pressure is applied to the inside of the suction chamber 26 by the fan portion 23 that is rotated by the driving of the motor portion 22, thereby being covered with the passage forming plate 28, and the slit suction port at the tip position among the numerous suction ports 24 and 25. Since all the suction ports 24 and 25 except 25a are closed with the round projecting piece 34 and the slit-shaped projecting piece 35, the front end portion of the space in the cover member 21 covered with the covering member 30 is focused. Negative pressure. As a result, air is sucked from the tip suction port 33. Thereby, dust collection operation | work can be performed so that a handy type vacuum cleaner may be operated from the front-end | tip suction port of a coating | coated member.

  In addition, a dust bag (not shown) that removes dust through the communication jig 40 is attached to the discharge port 27 that discharges air containing dust sucked in the suction chamber 26. That is, one end of the communication jig 40 is fixed to the opening of a dust bag that removes dust from the air containing dust attached to the outlet 27, and the other end is attached to the outlet 27. The communication jig 40 is bent in a “<” shape.

  As shown in FIGS. 5A and 5B, the communication jig 40 and the discharge port 27 are rotatably fixed by a C-shaped hook 45. Specifically, a pair of projecting pieces 46 project inward from the C-shaped latching tool 45 at positions opposite to both end edges of the C-shape. A pair of through holes 29 are formed at corresponding positions on the side of the discharge port 27 to which the pair of protruding pieces 46 are mounted. On the other hand, the communication jig 40 is formed with an insertion groove 41 that can be inserted into the tip end portions of the pair of protruding pieces 46 of the C-shaped latching tool 45 that has passed through the through hole 29.

  One end of the communication jig 40 is attached to the discharge port 27, and the pair of protruding pieces 46 of the C-shaped hook 45 are attached to the pair of through holes 29 of the discharge port 27, and pass through the through hole 29. The tip of the protruding piece 46 is inserted into the insertion groove 41 of the inner communication jig 40, and the communication jig 40 is locked to the discharge port 27. In the insertion groove 41 of the communication jig 40, the crests 42 extend over the entire circumference in the insertion groove 41 at equal intervals with the same width as the tips of the pair of protruding pieces 46 of the latching tool 45 to be inserted. Thus, the free rotation of the communication jig 40 that is formed and bent in a “<” shape is restricted.

  Note that the rotation of the communication jig 40 is limited to the peak portion 42 that is engaged with the tip of the protruding piece 46, but the C-shaped stopper 45 is an elastic member, so When a person rotates the communication jig 40 strongly, the C-shaped diameter of the latch 45 increases, and the tip of the communication piece 46 gets over the mountain portion 42 in the rotation direction. At this time, the protruding piece 46 of the C-shaped latching tool 45 does not get over the through hole 29 of the discharge port 27 and has elasticity, so the C-shaped diameter is immediately reduced. For this reason, every time the mountain part 42 is climbed, rotation and rotation are limited, but full rotation is possible while being mounted.

  Further, a convex portion is formed in the central portion of the C-shaped hook 45, and when the hook 45 is attached to the discharge port 27, the hook at one end of the safety cord for preventing the fall is hooked. A retaining hole 47 is formed.
