Description

Technical Field

[0001] The present invention relates to a technology for a dust scattering prevention attachment for an electric drill. Specifically, in the work of making holes in a wall or the like, it relates to an attachment for a dust storage container that can minimize even the slight scattering of dust that rises when removing a drill or collecting dust cut by a drill and a hole saw.

Background Art

[0002] The problem of asbestos, which has been said to have an adverse effect on the human body for many years, has been gaining awareness since about 50 years ago when national regulations were established, and it can be said that efforts have been made to prevent damage by setting the asbestos content rate and the like. However, currently, many of the buildings targeted for demolition work and facility improvement are those before the regulations, and the health damage to workers continues. In addition, the health damage caused by asbestos dust affects not only the workers engaged in the construction work but also the residents and pedestrians living near the work site due to scattering.

[0003] Such a problem of asbestos is particularly serious in the work of installing an air conditioner where an operator directly touches a wall or ceiling containing asbestos and performs a drilling operation because asbestos dust is inhaled through the mouth and nose and has a particularly adverse effect on the human body when it enters the body. In the drilling operation for this air conditioner installation, it is a manual operation using a drill or the like, and during the drilling operation at this time or during the operation of treating the dust collected during the operation, dust will inevitably be inhaled. Therefore, it can be said that a device for solving such a problem is necessary.

[0004] When installing the air conditioner pipes, specifically, there is a step of drilling a hole with an inner diameter of about 65 mm to 80 mm using a power tool such as an electric drill. Then, the building materials used on the wall with an inner diameter of about 65 mm to 80 mm will turn into fragments and powder. Also, the dust will scatter not only on the wall where the worker is working but also on the wall opposite to the working wall. As a result, not only the worker but also passers-by on the opposite side, for example, will inhale the dust. In particular, for the worker, this is a task that is repeated several times a day, and in the task of wiping off the dust on the cut wall and tools, asbestos will also be inhaled. Also, if this is repeated daily, the amount of dust inhaled cannot be minimized, and it can be said that the adverse effects on the human body are significant. And if the job with the risk of asbestos inhalation continues for a long time, the inhaled asbestos will stay in the lung tissue for a long time, and as a result, it is said that it is more likely to develop asbestosis, lung cancer, etc. It can be said that measures are needed to minimize such health hazards as much as possible.

[0005] Furthermore, deeply recognizing these current situations, the state has finally taken countermeasures. Since April 1, 2022, the Ministry of Health, Labour and Welfare has announced the obligation to report the results of the prior investigation on the presence or absence of asbestos, and the need to take measures to prevent scattering. Along with this, it is urgent to provide tools and methods that can avoid inhaling asbestos dust.

[0006] In view of the above problems, the inventor has already disclosed a technology with the invention name "Dust Scattering Prevention Attachment for Electric Drill" as a known technology in an attempt to solve such problems. (See Patent Document 1). Specifically, "aiming to reduce dust damage generated during drilling operations on walls etc. in construction work, and being able to reduce human damage caused by asbestos-containing building materials in buildings containing asbestos, especially minimizing scattering even when disposing of the collected dust", the problem is set, and as a solution, "The dust scattering prevention attachment for an electric drill according to the present invention is a dust scattering prevention attachment that uses a cylindrical body, a sliding container, and an elastic body having flexible flexibility for an electric drill. The sliding container is made of an elastic material, connects the main body of the electric drill and the cylindrical body, the shape of the sliding container is a frustum of a cone that widens towards one side, a plurality of circumferences of annular concave grooves are connected to the outer peripheral surface of the sliding container, and the inner peripheral surface of the sliding container has a surface property that smoothly connects." That's what it is. The invention described in Patent Document 1 can prevent the scattering of dust generated during cutting operations and can also collect dust into a container, but it cannot prevent the scattering of dust generated when removing these containers.

[0007] In addition, there is a technology with the invention name "Power tool system, power tool, and dust collector" (see Patent Document 2). Specifically, with the problem of "facilitating the removal of dust", the solution is as follows: "The power tool system includes a power tool and a dust collector. The power tool has a tool housing and a first connector 3. The dust collector is configured to be detachable from the power tool and collects dust. The dust collector has a dust collection housing 40 and a second connector 5. One of the first connector 3 and the second connector 5 has a flat terminal 51. The other of the first connector 3 and the second connector 5 has a spring terminal 31 that contacts the flat terminal 51 facing it. The flat terminal 51 is provided along the surface of the housing in which the flat terminal 51 is provided among the tool housing and the dust collection housing 40." It is expected that the dust scattering generated during the cutting operation can be prevented by the dust collector, and the dust scattering generated when removing a drill or the like can be prevented. However, the invention described in such a document is a so-called dedicated device and cannot be used as an attachment for existing electric drill drivers or the like. Also, it is different from the present invention that can be supplied at low cost.

[0008] In addition, there is a technology with the utility model name "Air drill equipped with a chip removal function" (see Patent Document 3). Specifically, with the problem of "providing an air drill equipped with a function of storing the chips that come out when drilling holes in metals such as aluminum or wood or wood in a dust bag attached to the drill body", the solution is as follows: "When drilling holes in aluminum or the like with an air drill, in order to prevent the chips that come out from scattering, the chips are sucked from a nozzle 7 attached parallel to the cone of the drill using the same air used, and stored in a dust bag 9 attached to the air discharge port of the drill body so that the chips after use can be processed, an air drill equipped with a chip removal function." However, the invention described in Patent Document 3 has a structure premised on an air drill used in a manufacturing factory or the like, and is different from the present invention used for power tools used in pipe installation work such as air conditioners.

Embodiments for Carrying Out the Invention

[0020] The dust scattering prevention attachment 1 for an electric drill according to the present invention is a dust scattering prevention attachment to be attached to an electric drill D, and is characterized in that a slide mechanism component 5 is provided at the tip of a sliding housing. The following will be described with reference to the drawings. Note that the overall shape of the dust scattering prevention attachment 1 for an electric drill according to the present invention and the shape of each part of the dimensions are not limited to the description described below, and can be changed within the scope of the technical idea of the present invention, that is, within the range of shapes and dimensions that exhibit the same operational effects.

[0021] FIG. 1 is a basic configuration explanatory diagram for explaining the basic configuration of the dust scattering prevention attachment 1 for an electric drill according to the present invention. FIG. 1(a) shows each member used for the electric drill D, and FIG. 1(b) shows a state in which each member is attached to the electric drill D. The following will provide a detailed explanation of each component used.

[0022] The dust scattering prevention attachment 1 for an electric drill is a dust scattering prevention attachment that uses a cylindrical body 20, a sliding housing 10, and a slide mechanism component 5 for the electric drill D. The sliding housing 10 is made of an elastic material, connects the main body of the electric drill D and the cylindrical body 20, and has a frustoconical shape that flares out toward the slide mechanism component 5 as its basic shape. A plurality of circumferential annular concave grooves are provided on the outer peripheral surface of the sliding housing 10, and the inner peripheral surface of the sliding housing 10 has a smoothly connected surface property.

[0023] The slide mechanism component 5 has technical features that can be regarded as the main part of the present invention. That is, when the drilling operation is completed by the drill bit 200 or hole saw 210 attached to the electric drill D and the front elastic body 40 attached to the wall is removed from the wall, it prevents the dust P adhering to the drill bit 200 or hole saw 210 from scattering. In particular, unlike the case of drilling from directly below upwards, when making a horizontal hole in the wall, such as in the piping work of an air conditioner, the amount of dust P spilling is significantly different. Therefore, by providing the so-called shutter-like slide mechanism of the present application, the operator can work safely without being exposed to the dust P regardless of the orientation of the ceiling or wall.

[0024] The sliding container 10 is formed of an elastic material such as rubber that is shaped to give a force that causes the cylindrical body 20 to slide accordingly and always return to its original state whether it is stretched or crushed when the drill bit 200 or hole saw 210 cuts into and penetrates the wall K, or is configured to slide inside the cylindrical body 20, or is configured such that the end of the sliding container 10 can be rolled up. Note that there are commercially available dust covers that are entirely bellows-shaped. However, although this also allows for free expansion and contraction due to such bellows, it can be said to include the problem of maintainability that dust P enters the unevenness of such bellows and becomes difficult to remove. Therefore, in the present invention, the inner surface of such a sliding container 10 has a surface property with as few uneven parts as possible.

[0025] The sliding container 11, different from the sliding container 10, uses a commercially available dust cover. Such a sliding container 11 is a container that only expands and contracts as a whole and allows for free expansion and contraction. However, it can be said to include the problem of maintainability that dust P enters the unevenness of such bellows and becomes difficult to remove.

[0026] The cylinder body 20 covers the drill bit 200 or the hole saw 210 and serves as a container for accommodating the dust P generated from the cutting edge. It moves back and forth with respect to the drill bit 200 or the hole saw 210 via the sliding container 10. Further, a flange portion 41 for sandwiching an elastic body 42 at the rear between the tip of the cylinder body 20 and the dust storage body 31 is provided at the tip end portion of the cylinder body 20.

[0027] The inner cylinder body 30 connects the slide mechanism main body portion 31 and the cylinder body 20, and the inner cylinder body 30 attached to the dust storage body 31 is inscribed in the cylinder body 20.

[0028] The slide mechanism main body portion 31 is a basic component constituting the slide mechanism component 5. That is, via a slide groove 36 provided in the slide mechanism main body portion 31, it enables the replacement of the slide wheel 32 and the slide lid 33, or operates an integral slide shutter 37.

[0029] The slide wheel 32 serves as a packing so that the dust P generated by the drill bit 200 and the hole saw 210 does not leak to the outside.

[0030] The slide lid 33 enables the prevention of scattering without missing even an extremely small amount of dust P that slightly rises when the present equipment is removed from the wall after the drilling operation by the drill bit 200 and the hole saw 210 is completed.

[0031] The slide lid fixture 34 is a member that holds the slide wheel 32 or the slide lid 33 attached by a slide groove 36 provided in the dust storage body so as not to fall off.

[0032] The attachment fixture 35 mainly connects the sliding container 11 and the inner cylinder body 30 and is a fixture for firmly holding so that dust does not leak from such a connection portion.

[0033] The slide groove 36 is a groove provided to guide the slide ring 32, the slide cover 33, and the integral slide shutter 37 to perform proper operations in the dust container 31.

[0034] The integral slide shutter 37 is a combination of two components, the slide ring 32 and the slide cover 33, which are integrated, and the slide cover 33 pushes out the slide ring 32.

[0035] The electric drill D is a power tool mainly for drilling holes. In the present invention, an existing commercially available electric drill driver or the like can be used. Such an electric drill D consists of a motor, a speed reducer, and a drill chuck, and is called "portable electric drill" in JIS C9605. Functionally, it is a portable version of a "drilling machine". Currently, the mainstream models have a double-insulated machine body made of an insulator. It is the most popular portable power tool and is also called the electric drill D, or simply the electric drill, electric driver, drill, or drill driver. When the electric drill D was invented, it was a dedicated power tool for attaching a drill bit 200 and rotating it in the forward direction to drill holes in wood or metal. Subsequently, various functions were added to the main body, and the tools attached to the tip became more abundant, expanding the working range. As a result, various operations such as drilling, tightening, loosening, polishing, and grinding became possible, and the name also became various electric drills D that additionally display their functional performance.

[0036] The front elastic body 40 has a ring shape corresponding to the slide mechanism main body 31, and is sandwiched between the wall surface K to be cut by adhesion, and is further pressed to deform according to the uneven shape of the wall or the like. Specifically, for example, there is a fluffy urethane used in daily life. It is a material obtained by foaming a synthetic resin such as polyurethane as a raw material and processing it into a sponge shape, and then cutting it into a shape according to the application, which is called "urethane sponge" abbreviated as "urethane". Similarly, even urethane sponges made of polyurethane can be made into various hardnesses and shapes such as "soft urethane foam", "hard urethane foam", and "low resilience urethane foam" by changing the degree of foaming and the manufacturing method, and the great feature is that it can be selected according to the intended use. Urethane sponge is also called urethane foam. The material obtained by foaming the raw material into a sponge shape is called foam, and urethane sponge and urethane foam basically refer to the same thing. Furthermore, such urethane foam has a rough surface due to foaming, and when the front elastic body 40 is pressed against the wall surface K, it exhibits an anti-slip function. Also, a material with flexibility and peelability by controlling the crosslinking density of the silicone resin to leave a slight free fluidity can be said to be a suitable material. In the dust scattering prevention attachment 1 for an electric drill according to the present invention, when there are irregularities on the wall surface K, by sandwiching and pressing the front elastic body 40 between the wall surface K and the slide mechanism main body 31, stable drilling corresponding to the irregularities is made possible.

[0037] The flange portion 41 is a stepped portion for sandwiching the rear elastic body 42 between the tip of the cylindrical body 20 and the slide mechanism main body 31.

[0038] The rear elastic body 42 is sandwiched between the tip of the cylindrical body 20 and the slide mechanism main body 31 to enable stable drilling.

[0039] The usage method will be described using the embodiments of the present invention. The inventor of the present application has already obtained patents related to dust prevention (Patent No. 7493652: Method for preventing dust scattering in an electric drill, Patent No. 7483998: Dust scattering prevention attachment for an electric drill, and Patent No. 7470234: Dust scattering prevention auxiliary tool for an electric drill and wall drilling method using the same). Among them, the dust scattering prevention attachment for an electric drill will be described as an example.

[0040] First, the drill bit 200 and hole saw 210 mounted on the chuck part of the electric drill D are rotatably supported, and the cylindrical body 20 and the sliding accommodation part 10 are covered. A rear elastic body 42 is attached to the flange part 41 provided at the tip of the cylindrical body 2 and a slide mechanism component 5 is further attached to the tip thereof. Further, the front elastic body 40 is pressed between the wall K to perform the drilling operation. In this case, the front elastic body 40 is deformed by the pressing and deformed and adhered to the unevenness of the wall, so that dust does not leak. As shown in Fig. 9(a), first, a reference hole 50 is opened with the drill bit 200, and then, as shown in Fig. 9(b), an inner wall opening hole 52 is opened with the hole saw 210. At that time, chips and dust P accumulate inside the hole saw 210. After the drilling operation is completed, the electric drill D with the dust scattering prevention attachment 1 for the electric drill attached thereto is removed. In addition, as shown in Fig. 9(c), when the wall K is double and there is an inner wall UK and an outer wall SK, it is necessary to perform the drilling operation until the guide hole 51 penetrates the outer wall SK. When opening the guide hole 51, it is desirable to attach a container 60 as shown in Fig. 5 so that dust is not discharged to the outside of the wall. The outer wall opening hole 53 is opened by the hole saw 210 from the outer wall SK side guided by the guide hole 51. As shown in Fig. 9(d), it is necessary to block the inner wall opening hole 52 with a curing tape Y or the like before opening the outer wall opening hole 53 by the hole saw 210 from the outer wall SK side.

[0041] The reference hole 50 is a hole that is first opened to guide a circular cutting tool such as the hole saw 210 when opening the target inner wall opening hole 52.

[0042] The guide hole 51 is a hole that guides the center of the reference hole 50 on the inner wall and the outer wall opening hole 53 that penetrates through the opening hole.

[0043] The inner wall opening hole 52 is the hole that serves the purpose of the inner wall UK, and it is the hole opened using a circular cutting tool such as a hole saw with the reference hole 50 as the center.

[0044] The outer wall opening hole 53 is the hole that serves the purpose of the outer wall SK, and it is the hole opened using a circular cutting tool such as a hole saw with the guide hole 51 as the center.

[0045] The adhesive gel 100 is a jelly-like semi-solid material that has the flexibility of a liquid and the elasticity of a solid, and it is used for sticking to the flange portion 41 of the cylinder 20 or the wall surface K of the front elastic body 40 as needed.

[0046] The drill bit 200 is attached to the electric drill D and, when rotated, is the blade for making holes in objects and performing cutting. Generally speaking, there are those for woodworking, for metal, for concrete, etc.

[0047] The hole saw 210 is a tool that is attached to an electric drill driver or an impact driver and used to make large holes that cannot be made with a drill in wood or metal. There are various types and sizes according to the uses and purposes, and it is possible to make holes in wood, resin, iron plates, etc.

[0048] The wall surface K is a flat building material that constitutes the wall regardless of the outer wall or the inner wall. In a general house, the outer wall SK and the inner wall UK exist with the stud M sandwiched between the walls, and when making a hole for the duct of the air conditioner, it is necessary to make a hole that penetrates through the outer wall SK and the inner wall UK.

[0049] Dust P is powdery, fine solid particles that float in the air in a dust-like state, and are defined by the International Organization for Standardization as "solid suspended matter with a particle size less than 75 μm". In particular, dust P containing asbestos, which has a significant impact on the health of workers when inhaled, is a problem.

[0050] The curing tape Y is a tape that can be used for a wide range of applications, such as bundling things and temporary fixing. It is made on the premise of being peeled off and has the characteristic of little adhesive residue. In the present invention, in order to prevent dust P from scattering into the room when making an outer wall opening hole 53 from the outer wall SK side after making an inner wall opening hole 52 in the inner wall UK by taking advantage of the function of having little adhesive residue.

As shown in FIG. 9(a), first, a reference hole 50 is drilled with a drill bit 200, and then, as shown in FIG. 9(b), an inner wall opening hole 52 is drilled with a hole saw 210. At this time, chips and dust P accumulate inside the hole saw 210. After the drilling operation is completed, the electric drill D equipped with the dust scattering prevention attachment 1 for the electric drill is removed. Note that, as shown in FIG. 9(c), when the wall K is double and there is an inner wall UK and an outer wall SK, it is necessary to perform the drilling operation until the guide hole 51 penetrates the outer wall SK. When opening the guide hole 51, it is desirable to mount a container 60 as shown in FIG. 5 so that dust is not discharged to the outside of the wall, and the guide hole 51 is used for guiding to open an outer wall opening hole 53 with the hole saw 210 from the outer wall SK side. As shown in FIG. 9(d), before opening the outer wall opening hole 53 with the hole saw 210 from the outer wall SK side, it is necessary to block the inner wall opening hole 52 with a curing tape Y or the like.
