JP5476399B2 - Simple dustproof cover - Google Patents

Description

  The present invention is a simple dustproof device that collects chips generated when drilling a hole in a ceiling surface or the like by a drilling tool such as a hole saw that is detachably attached to the tip of an electric tool such as a drill so as not to be scattered. It is about the cover.

  When installing various instruments such as ceilings, downlights, and detectors at the construction site, or when passing through the refrigerant pipe of an air conditioner, it is necessary to make a hole in a gypsum board or the like constituting the ceiling surface or wall surface. In this case, in order to prevent scattering of chips and the like generated during the drilling operation, the surroundings of the work place are cured to simplify the cleaning operation. However, since it is necessary to perform curing for all the punched portions, there is an inconvenience that much time is required for the curing operation.

  Therefore, in place of such curing work, construction using a dust cover to be attached to a drilling tool is increasing. For example, as disclosed in Patent Document 1, there is a dust cover provided integrally with a drilling tool. This dust-proof cover has a transparent bowl shape surrounding the outer periphery of a drilling tool equipped with a drill, a cutting blade or the like, and is directly screwed to the drilling tool.

  On the other hand, in the dustproof cover described in Patent Document 2, a cover to be attached to a power tool such as a drill is shown. This cover is not attached to a drilling tool, but is configured to be attached to a relay adapter attached to a power tool such as a drill. In particular, since the dust-proof cover described in Patent Document 2 is provided in a bellows-tube shape that can be expanded and contracted in the axial direction, it is lighter and easier to handle than a conventional bowl-shaped dust-proof cover. .

  Furthermore, Patent Document 3 discloses a special dustproof cover. This dust-proof cover does not collect the chips scattered on the surface on which the drilling tool such as a horusoe is present as in Patent Document 1 and Patent Document 2, but falls to the back side of the workpiece through which the drilling tool has penetrated. It is configured so that chips can be collected. That is, since the dust-proof cover of Patent Document 3 needs to be adhered to the back surface of the workpiece, it is a dust-proof cover provided with adhesive means such as an adhesive, a magnet, and a micro suction hole. In particular, in this chip scattering preventing device, a container-like cover having heat resistance such as fluoro rubber, silicon rubber, glass fiber or the like is used.

  All the conventional dustproof covers have a problem in the means for attaching the dustproof cover. That is, since the cover of Patent Document 1 is integrated with a drilling tool, the drilling tool itself is bulky, and handling during tool storage or transportation is difficult.

  On the other hand, as in Patent Document 2, a dust-proof cover attached to a power tool such as a drill can be stored and transported separately from the drilling tool and the dust-proof cover, so that it is easier to handle than the dust-proof cover of Patent Document 1. It has become. However, since this dustproof cover is attached to a relay adapter attached to a power tool such as a drill, the shape of the details varies depending on the manufacturer even if the power tool is changed from an electric drill to an electric screwdriver. If it has changed, the relay adapter may not be attached. Therefore, the electric tool that can be fitted with the dustproof cover of Patent Document 2 is limited to the one that can be fitted with the relay adapter, and there is a disadvantage that it cannot be attached to other electric tools.

  And since the dustproof cover of patent document 2 has comprised the bellows-tube shape which can be expanded-contracted, it has the structure where the collected chip | tip is easy to adhere to the inside of a bellows-tube shape. Therefore, even if the cover is made of a transparent material, it is difficult to maintain the transparency of the cover due to the chips adhering to the inside of the cover, which may hinder the rotary cutting work with the drilling tool. . In addition, the work for removing the chips collected inside the bellows-like cover also requires a lot of work.

  In addition, as in Patent Document 3, in a special dustproof cover configured to collect chips falling on the back side of the workpiece, in particular, since the dustproof cover is bonded to the backside of the workpiece, The chips generated when the hole is drilled in the ceiling surface cannot be collected on the lower surface of the ceiling. Therefore, it is not suitable for the work for attaching the ceiling, downlight, sensor and other instruments to the ceiling.

  Moreover, although the dustproof cover described in Patent Document 3 also has a folding function, this dustproof cover employs a heat-resistant material such as fluorine rubber, silicon rubber, glass fiber, incombustible or flame retardant nonwoven fabric, Furthermore, it has a configuration provided with adhesive means such as an adhesive, a magnet, and a micro suction hole. As a result, even if the folding function is provided, there is a possibility that these materials and attaching means may hinder the dustproof cover from being folded compactly.

  Therefore, the present invention was created to solve the above-mentioned problems, and the dustproof cover configured separately from the drilling tool can be easily attached even if the type and manufacturer of the power tool are different, The purpose is to provide a simple dustproof cover that is lightweight, easy to operate, can maintain transparency when using drilling tools, can easily remove collected chips, and can be folded in a very compact manner. It is what.

A dust-proof cover comprising a bottomed cylindrical cover body 10 that covers the periphery of the drilling tool with a transparent synthetic resin material, and a shank part Q1 of the drilling tool Q is inserted into the bottom 11 of the cover body In the simple dustproof cover in which the connecting body 12 is opened and the cover body 10 is detachably mounted between the drilling tool Q and the electric tool P through the connecting hole 12 , the cover body 10 is transparent. A sheet material 1 made of synthetic resin is assembled and formed, and the bottom portion 11 is configured such that a plurality of the folded sheet materials 1 are superposed, and the connecting hole 12 is formed of the bottom portion 11. Multiple sheets of polymerized In which is provided so as to penetrate the.

In the second means, the bottom portion 11 of the cover body 10 is formed with a strip-shaped overlap piece 15 along the periphery, and when the cover body 10 is formed, the overlap piece 15 is not attached to the cover body 10. It is comprised so that it may superpose | polymerize inside the side part 14. FIG.

  As in claim 1 of the present invention, a bottomed cylindrical cover body 10 that covers the periphery of the drilling tool is formed of a transparent synthetic resin material, and a shank portion of the drilling tool Q is formed on the bottom 11 of the cover main body 10. A connecting hole 12 through which Q1 is inserted is opened, and the cover main body 10 is detachably mounted between the drilling tool Q and the electric tool P through the connecting hole 12, so that the electric tool No need for a relay adapter or the like to be attached to the PC, and it can be easily installed regardless of the type and manufacturer of the power tool. Moreover, since the cover body 10 is formed of a synthetic resin material in a bottomed cylindrical shape, the cover body 10 as a whole has a property of being easily bent, so even when the height of the drilling tool is different. Can be used flexibly. Furthermore, since the bottomed cylindrical cover body 10 does not collect chips inside unlike the bellows shape, it is possible to maintain transparency for a long time.

In addition , the display unit 10 is formed by assembling a transparent sheet material 1 made of synthetic resin, and the bottom portion 11 is configured such that a plurality of the folded sheet materials 1 are superposed, The connection hole 12 is provided so as to penetrate through the plurality of sheet materials 1 superposed on the bottom portion 11, so that the strength of the connection hole 12 can be increased even with a thin sheet material 1. As a result, even if the lightweight sheet material 1 is assembled to form the cover body 10, the connecting hole 12 mounted between the electric power tool P and the drilling tool Q has extremely high strength and excellent durability. It is configured. And since the assembled cover main body 10 can be returned to the original sheet | seat material 1, the collected chips can be removed easily and it can also be folded very compactly.

As in claim 2 , the bottom portion 11 of the cover body 10 is formed with a band-shaped overlap piece 15 along the periphery, and when the cover body 10 is formed, the overlap piece 15 is on the side of the cover body 10. Since it is comprised so that it may superpose | polymerize inside the part 14, the bottom part 11 and the side part 14 will be in a close state through this superposition | polymerization piece 15. FIG. As a result, it is possible to prevent leakage of chips accumulated on the bottom 11.

  According to the present invention, it can be easily installed regardless of the type and manufacturer of the power tool, is light and easy to operate, and can maintain transparency when using a drilling tool. The initial objectives such as easy powder removal and folding in a very compact form were achieved.

  Examples of the present invention will be described below. The dustproof cover of the present invention is a simple dustproof cover that collects chips generated when the drilling tool Q is used (see FIG. 5). This drilling tool Q is, for example, a tool that is selected from a hole saw, a universal cone, a core drill, and the like and is detachably attached to the tip of the electric power tool P (see FIG. 1). On the other hand, an electric drill or an electric screwdriver is used as the electric tool P.

  The dustproof cover of the present invention comprises a bottomed cylindrical cover body 10 that covers the periphery of a drilling tool with a transparent synthetic resin material (see FIG. 1). And the connection hole 12 which penetrates the shank part Q1 of the drilling tool Q in the bottom part 11 of the cover main body 10 is opened.

  The cover body 10 in the illustrated example is formed by folding and assembling a transparent synthetic resin sheet material 1 (see FIG. 2), and is formed in a bottomed rectangular tube shape that covers the periphery of the drilling tool Q. (See FIG. 1). The bottom 11 of the fixed base 10 is in a state where a plurality of folded sheet materials 1 are superposed (see FIG. 2). And the connecting hole 12 which penetrates the several sheet | seat material 1 which superposed | stacked this bottom part 11 is provided, The shank part Q1 of the drilling tool Q is inserted in this connecting hole 12, and the drilling tool Q, the electric tool P, The cover body 10 is detachably mounted between the two. At this time, if the positions of the connecting holes 12 to be opened in the respective sheet materials 1 are slightly shifted, even if the diameters of the shank portions Q1 are different, the connecting holes 12 are displaced from each other, so that the shank portions Q1 It becomes possible to match the diameter.

  Moreover, the cover main body 10 can use the bottomed cylindrical cover main body 10 integrally molded with a synthetic resin material in addition to the illustrated example (not shown). In this case, it is possible to form the bottom portion 11 to be thicker than other thicknesses, or to provide the connection hole 12 with a member that reinforces the connection hole 12 that opens in the bottom portion 11.

  The sheet material 1 constituting the illustrated cover main body 10 is provided with a fold 2 that forms the cover main body 10 and a fastening portion 3 that fastens the end of the sheet material 1 (see FIG. 2). And if the sheet | seat material 1 is folded along this crease | fold 2, the cover main body 10 will be comprised (refer FIG. 3, FIG. 4). Further, the fastening portion 3 is inserted and locked into the cut portion 5 formed in the sheet material 1. At this time, it is also possible to make the length of the cut portion 5 longer so that the insertion position of the fastening portion 3 can be adjusted along the length of the cut portion 5 (see FIG. 4).

  Further, a plurality of bottom members 6 are formed in a portion located at the bottom portion 11 of the cover main body 10, and a connecting hole 12 is opened in each bottom member 6 (see FIG. 2). 11, a strip-shaped polymer piece 15 is formed along the periphery. The overlapping piece 15 is configured such that when the cover body 10 is formed, the overlapping piece 15 is overlapped inside the side portion 14 of the cover body 10 (see FIG. 1). In the illustrated example, among the plurality of bottom members 6 to be superposed, a superposed piece 15 is formed around the bottom member 6 located on the uppermost surface (see FIG. 3).

  Further, a contact piece 16 that is brought into contact with the perforated surface is bent at the upper opening of the cover body 10 (see FIG. 1). When the contact piece 16 is brought into contact with the surface to be drilled, the gap between the opening of the cover body 10 and the surface to be drilled can be reduced as much as possible. The contact piece 16 in the illustrated example is bent toward the inside of the opening, but the contact piece 16 can be bent toward the outside of the opening (not shown).

As another reference example , a plurality of cut lines 4 are formed along the opening 13 of the cover body 10 (see FIG. 6). By cutting the sheet material 1 from the cut line 4, the size of the fixed base 10 can be adjusted to the size of the drilling tool Q.

  Moreover, although the cover main body 10 of the example of illustration is all formed in the bottomed square cylinder shape, the shape of the cover main body 10 can be changed arbitrarily. For example, as shown in FIG. 7 (a), from the substantially fan-shaped sheet material 1, a conical bottomed cylindrical cover body 10 is formed as shown in FIG. 7 (b). Furthermore, as shown in FIG. 8, it is also possible to form the cover body 10 in a polygonal bottomed rectangular tube shape.

  Although this invention cover is demonstrated as a tool used when opening a hole in a ceiling surface, the position which opens a hole with the drilling tool Q is not limited to a ceiling surface. Further, the shape and material of the cover of the present invention can be arbitrarily changed, and the design can be freely changed without changing the gist of the present invention.
