[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.

[0025] Similarly, some components may not be shown in the drawings, or may be shown in perspective or in simplified form.

[0026] (1) First, a dust receiving bag 1 according to an embodiment of the present invention will be specifically described with reference mainly to FIGS.

[0027] 1 to 3 are perspective views (parts 1 to 3) of a dust receiving bag 1 according to an embodiment of the present invention, and FIG. 4 is a perspective view of an attachment member 16 of the dust receiving bag 1 according to an embodiment of the present invention.

[0028] In apartment buildings and the like, holes for pipes and the like are often pre-formed in the building wall surface 50, but in other housing where such holes are not pre-formed in the building wall surface 50, holes are formed as needed during drilling work using a drilling machine 40 such as a core drill machine.

[0029] Amendments to asbestos-related laws and regulations will take effect in October 2023, and one possible approach is to securely catch and dispose of dust that falls from the board components of the building wall 50 and that occurs during hole penetration work using a blanket-like covering material laid on the floor below the building wall 50, but in cases where multiple installation works are carried out in one house, sweeping up the collected dust outdoors can be a tedious task. Dust can sometimes be simply caught in a plastic garbage bag, but the opening of the bag does not easily widen, making it difficult to catch all of the dust.

[0030] Asbestos has not been used since 2006, and it is believed that board materials generally known as gypsum boards are mainly used, but the dust collection bag 1 can also be used effectively for drilling holes in such board materials.

[0031] The dust receiving bag 1, which receives dust generated during drilling work on a building wall surface 50, has a front member 11, a rear member 12, a left member 13 connecting the front member 11 and the rear member 12, and a right member 14 connecting the front member 11 and the rear member 12.

[0032] The three-dimensional bag shape of the dust collecting bag 1 is almost symmetrical not only in the left-right direction but also in the front-to-back direction, and by simply changing the inside and outside of the bag as needed due to bag deterioration, etc., the dust collecting bag 1 can be used repeatedly as a dust collection bag in so-called air conditioning installation work, electrical installation work, etc.

[0033] The main body of the dust collecting bag 1 is made of paper, not plastic, so that the bag can be easily disposed of after use.

[0034] Such papers are, for example, papers that have been coated to improve their strength, and are also long-lasting and economical.

[0035] The front member 11 and the rear member 12 are flat plate members having a substantially rectangular shape. The lower end of the front member 11 is connected to the lower end of the rear member 12. The left member 13 and the right member 14 are foldable flat plate members having a substantially triangular shape.

[0036] In the left side member 13 and the right side member 14, not only is a central fold line formed in the vertical direction for folding between a folded state and an extended state, but a slit 101 is also formed into which the outer tab 103 of the attachment member 16 is inserted from above when the attachment member 16 is attached from inside the bag interior space 10 or from outside the bag interior space 10.

[0037] The left and right side members 13, 14 are folded in an accordion-like manner, making it easy to open and close the bag. The dust collection bag 1 is folded into a compact size and does not take up much space, making it easy to transport.

[0038] The upper ends of the left surface member 13 and the right surface member 14 are formed with a rounded shape that protrudes upward.

[0039] As shown in FIGS. 5 to 7, embodiments in which such an upwardly convex roundness is not formed are also conceivable.

[0040] Here, Figures 5 and 6 are oblique views (parts 1 and 2) of a dust receiving bag 1 according to a first modified embodiment of the present invention, and Figure 7 is an oblique view of a dust receiving bag 1 according to a second modified embodiment of the present invention.

[0041] An attachment member 16 is provided which is detachably attached to the upper end of the left surface member 13 or the upper end of the right surface member 14 depending on the rotation direction of the drilling drill of the drilling machine 40 used in the drilling operation. The attachment member 16 is a flat plate member having a substantially rectangular shape.

[0042] In cases where the drill rotation speed is high and dust is likely to scatter, attachment member 16, which is an auxiliary side dust receiving mount, is attached to the left or right side of the main body depending on the shape of the main body. The drill basically rotates to the right as indicated by arrow A, and a large portion of the dust scatters toward the right side member 14 rather than the left side member 13. Therefore, attachment member 16 is typically attached to the right side member 14 to efficiently catch the dust that scatters toward the right side of the main body.

[0043] In the attachment member 16, not only is the outer tab 103, which is convex downward, formed for insertion into the slit 101 of the left-side surface member 13 or the right-side surface member 14, but the inner tab 102, which is convex downward, is also formed by notching for hooking onto the upper end of the left-side surface member 13 or the right-side surface member 14.

[0044] A step 104 is formed at the rear end of the attachment member 16 for hooking onto the front member 11 or the rear member 12 so that the attachment member 16 is stabilized when the attachment member 16 is attached from inside the bag interior space 10.

[0045] The attachment member 16 is detachably erected and can be freely removed, so that high versatility in response to the demands of the construction site can be expected.

[0046] As shown in Figs. 3 and 5, an embodiment is also conceivable in which the attachment member 16, which is a so-called horizontal plate member serving as a plate for preventing lateral leakage of dust, is not attached.

[0047] Of the left surface member 13 and the right surface member 14, the rear end edge of the portion of the attachment member 16 that protrudes upward from the upper end of the surface member to which the attachment member 16 is attached is on a plane that includes the rear surface of the rear surface member 12. When the bag is attached to the building wall surface 50, the rear surface of the rear surface member 12 contacts the building wall surface 50, and the rear end edge of the portion of the attachment member 16 that protrudes upward is in tight contact with the building wall surface 50.

[0048] When the attachment member 16 is attached from inside the bag interior space 10, the open state of the front member 11 and the rear member 12 is stabilized by forming a taper in the portion of the attachment member 16 that protrudes downward from the upper end of the left side member 13 and the right side member 14 so that the front member 11 and the rear member 12 are in close contact with the inside of the bag interior space 10.

[0049] Even when drilling work is performed near the corners of the building wall surface 50, the main body is guaranteed to be firmly attached to the building wall surface 50, so there are almost no inconvenient gaps that could cause the spillage of scattered dust, and the dust can be efficiently received.

[0050] (2) Next, the dust receiving bag 1 according to the embodiment of the present invention will be described in more detail with reference mainly to FIGS.

[0051] A bag member 30 for receiving dust is set in the bag internal space 10 surrounded by the front member 11, rear member 12, left member 13, and right member 14. The bag is attached to the building wall surface 50 by attaching the lower end of the front member 11, the rear end of the left member 13, and the rear end of the right member 14 to the building wall surface 50 with tape members 20. The rear side of the open end of the bag member 30 is attached to the building wall surface 50 with tape members 20.

[0052] The tape member 20 used for such main body attachment is a general-purpose tape member such as masking tape used in construction work, etc. By attaching the bag member 30 to the building wall surface 50, inconvenient gaps that could cause scattered dust to spill out are almost completely eliminated, and dust can be efficiently caught.

[0053] The bag member 30 is a 45-liter general-purpose garbage vinyl bag or the like, and is inserted into the bag internal space 10 inside the main body for use, and then disposed of without any problems when construction is completed.

[0054] Of the left surface member 13 and the right surface member 14, the rear end edges of the portions of the attachment members 16 that protrude upward from the upper ends of the surface members to which the attachment members 16 are attached are also attached to the building wall surface 50 with tape members 20 so as to be in close contact with the building wall surface 50, but it is also possible that the rear end edges of such portions of the attachment members 16 cannot be attached to the building wall surface 50 with tape members 20.

[0055] Of course, in cases where disposable bags are more preferable than repeated use of the bag by replacing the bag member 30, a mode in which the bag member 30 is not set in the bag internal space 10 is also conceivable.

[0056] (3) Next, the dust receiving bag 1 according to the embodiment of the present invention will be described in more detail with reference mainly to FIGS.

[0057] Ear members 15 are provided on the upper end of the rear member 12 so as to protrude upward compared to the upper ends of the left and right surface members 13 and 14. The ear members 15 are flat members having a substantially rectangular shape.

[0058] 7, an embodiment in which no ear members 15 are provided at all is also conceivable. Of course, an embodiment in which ear members 15 are erected only at the upper end of the front member 11 or the upper end of the rear member 12 is also conceivable.

[0059] The bag may be attached to the building wall surface 50 by attaching the ear members 15 to the building wall surface 50 with the tape members 20.

[0060] When the bag member 30 is set in the bag internal space 10, it is also possible to attach the tape member 20 to the rear side of the opening end of the bag member 30 that is placed over the ear member 15, thereby attaching the ear member 15 to the building wall surface 50 together with the bag member 30.

[0061] In addition, the rear side of the open end of the bag member 30 may be inserted into the gap between the ear member 15 and the wall surface 50 of the building.

[0062] As described above, by attaching the lower end of the front member 11, the rear end of the left-side member 13, and the rear end of the right-side member 14 to the building wall surface 50 with the tape member 20, the bag can be securely attached to the building wall surface 50, and by inserting the bag member 30 into the gap, inconvenient gaps that could cause scattered dust to spill out are almost eliminated, allowing the dust to be efficiently received. [Industrial Applicability]

[0063] The dust collection bag of the present invention can efficiently collect dust generated during drilling work on the wall of a building, and is useful as a dust collection bag for collecting dust generated during drilling work on the wall of a building. [Explanation of symbols]
