Modes for Carrying Out the Invention

[0024] With reference to the drawings, the embodiments in the present invention will be described in detail.

[0025] The same applies hereinafter, but some components may not be shown in the drawings, or may be shown perspectively or omitted.

[0026] (1) First, with reference mainly to FIGS. 1 to 4, the dust receiving bag 1 of the embodiment in the present invention will be specifically described.

[0027] Here, FIGS. 1 to 3 are perspective views (one to three) of the dust receiving bag 1 of the embodiment in the present invention, and FIG. 4 is a perspective view of the attachment member 16 of the dust receiving bag 1 of the embodiment in the present invention.

[0028] In condominiums and the like, holes for piping and the like are often formed in the building wall surface 50 from the beginning. However, in other houses where such holes are not formed in the building wall surface 50, the holes are formed as needed by a drilling operation using a drilling machine 40 such as a core drill.

[0029] The amendment of the asbestos-related laws and regulations was carried out in October 2023. It is conceivable that the dust generated during the hole penetration work, which falls from the board members of the building wall surface 50, is firmly received by a curing member such as a blanket spread on the floor below the building wall surface 50 and then discarded. However, when multiple installation works are carried out in a single house, the work of sweeping the received dust outdoors tends to be troublesome. The dust may be simply received in a garbage plastic bag or the like, but since the bag receiving opening does not easily expand, it is difficult to completely receive the dust.

[0030] There has been no asbestos use since 2006, and it is generally considered that board members called gypsum boards are mainly used. However, the dust receiving bag 1 can also be suitably used for the hole penetration work of such board members.

[0031] The dust receiving bag 1 for receiving the dust generated during the drilling operation of the 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 receiving bag 1 is substantially symmetric not only in the left-right direction but also in the front-back direction. By exchanging the front and back of the bag according to the need caused by bag deterioration or the like, the dust receiving bag 1 as a dust collection bag in so-called air conditioner work and electrical work can be used repeatedly.

[0033] Since the main body manufacturing material of the dust receiving bag 1 is paper instead of plastic or the like, it is easy to discard the bag after use.

[0034] Such paper is, for example, paper with a coating for improving strength, and it is 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 and the lower end of the rear member 12 are connected. The left member 13 and the right member 14 are flat plate members having a foldable substantially triangular shape.

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

[0037] Since the folding specifications of the left member 13 and the right member 14 are of the so-called accordion type, it is easy to open and close the bag. Since the dust receiving bag 1 is folded and made compact without taking up much space, it is also easy to carry the bag.

[0038] At the upper ends of the left member 13 and the right member 14, rounded portions that are convex upward are formed.

[0039] As shown in FIGS. 5 to 7, a mode in which such a rounded portion that is convex upward is not formed is also conceivable.

[0040] Here, FIGS. 5 and 6 are perspective views (parts one and two) of the dust receiving bag 1 of the first modification of the embodiment in the present invention, and FIG. 7 is a perspective view of the dust receiving bag 1 of the second modification of the embodiment in the present invention.

[0041] An attachment member 16 is provided which is detachably erected on the upper end of the left side member 13 or the upper end of the right side member 14 according to the rotation direction of the drilling bit 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 rotational speed of the drilling bit is high and dust is likely to scatter, the attachment member 16, which is a side dust receiving backing sheet as an auxiliary part, is attached to the left side of the main body or the right side of the main body according to the main body shape. The rotational direction of the drilling bit is basically the rightward direction indicated by the arrow A, and a significant portion of the dust scatters to the side of the right side member 14 rather than to the side of the left side member 13. Typically, the attachment member 16 is attached to the side of the right side member 14 to efficiently receive the dust scattered to the right side of the main body.

[0043] In the attachment member 16, not only an outer tab 103 that protrudes downward is formed for insertion into the slit 101 of the left side member 13 or the right side member 14, but also an inner tab 102 that protrudes downward is formed by a cut for engagement with the upper end of the left side member 13 or the right side member 14.

[0044] When the attachment member 16 is mounted from the inside of the bag inner space 10, a step 104 for engagement with the front member 11 or the rear member 12 is formed at the rear end of the attachment member 16 so that the attachment member 16 is stabilized.

[0045] Since the attachment member 16 is detachably erected and can be freely removed, high flexibility according to the requirements of the construction site is expected.

[0046] As shown in FIGS. 3 and 5, an aspect where the attachment member 16, which is a so-called horizontal plate member as a dust lateral leakage prevention plate, is not attached is also conceivable.

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

[0048] When the attachment member 16 is attached from the inside of the bag internal space 10, a taper that is substantially in close contact with the front face member 11 and the rear face member 12 from the inside of the bag internal space 10 is formed in the portion of the attachment member 16 that protrudes downward from the upper ends of the left face member 13 and the right face member 14 so that the open states of the front face member 11 and the rear face member 12 are stabilized.

[0049] Even when drilling work is performed near the corner of the building wall surface 50, a firm body close contact with the building wall surface 50 is guaranteed, so that almost no inconvenient gaps that cause spillage of scattered dust occur, and the dust can be efficiently received.

[0050] (2) Next, with reference mainly to FIGS. 1 to 3, the dust receiving bag 1 of the embodiment in the present invention will be described more specifically.

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

[0052] The tape member 20 used for such body mounting or the like is a general-purpose tape member such as a curing tape used for construction work or the like. Inconvenient gaps that cause spillage of scattered dust hardly occur due to the attachment of the bag member 30 to the building wall surface 50, and dust can be efficiently received.

[0053] The bag member 30 is a 45-liter general-purpose garbage plastic bag or the like, and after being inserted into the bag inner space 10 inside the main body and used, it is discarded without problems when the construction is completed.

[0054] Among the left face member 13 and the right face member 14, the rear edge of the portion of the attachment member 16 that protrudes upward from the upper end of the face member on which the attachment member 16 is mounted is also attached to the building wall surface 50 with the tape member 20 so as to be in close contact with the building wall surface 50. However, a mode in which the rear edge of such a portion of the attachment member 16 is not attached to the building wall surface 50 with the tape member 20 is also conceivable.

[0055] Of course, in a case where disposable bag use is more suitable 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 inner space 10 is also conceivable.

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

[0057] An ear member 15 is provided so as to protrude upward at the upper end of the rear face member 12 as compared with the upper ends of the left face member 13 and the right face member 14. The ear member 15 is a flat plate member having a substantially square shape.

[0058] As shown in FIG. 7, a mode in which the ear member 15 is not provided at all is also conceivable. Of course, a mode in which the ear member 15 is erected only on one of the upper ends of the front face member 11 and the rear face member 12 is also conceivable.

[0059] In addition, the bag may be attached to the building wall surface 50 by attaching the ear member 15 to the building wall surface 50 with the tape member 20.

[0060] When the bag member 30 is set in the bag inner space 10, a mode in which the ear member 15 is attached to the building wall surface 50 together with the bag member 30 by attaching the tape member 20 to the rear side of the open end portion of the bag member 30 covered with the ear member 15 is also conceivable.

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

[0062] As described above, by attaching the lower end portion of the front member 11, the rear end portion of the left side member 13, and the rear end portion of the right side member 14 to the building wall surface 50 with the tape member 20, the bag can be firmly attached to the building wall surface 50, and almost no inconvenient gaps that cause spillage of scattered dust occur due to the insertion into the gap of the bag member 30, and the dust can be efficiently received.

Industrial Applicability

[0063] The dust receiving bag in the present invention can efficiently receive the dust generated in the drilling work on the building wall surface, and is useful for the purpose of being used as a dust receiving bag that receives the dust generated in the drilling work on the building wall surface.
