Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since the attachment angle between the grip handle and the attachment object in the adapter described in Patent Document 1 is always constant, when performing a cleaning operation using a cleaning tool equipped with this adapter, it may not lead to an improvement in cleaning efficiency. Further, when preparing a plurality of adapters so that the attachment angles between the grip handle and the attachment object are different, there are problems that the manufacturing cost of the entire cleaning tool increases and it takes time to replace the adapter during the cleaning operation.

[0006] The present invention aims to solve the aforementioned conventional problems by providing a cleaning tool attachment that allows for easy modification of the mounting angle of the gripping handle to the cleaning body, and reduces the overall manufacturing cost of the cleaning tool, as well as a cleaning tool equipped with this cleaning tool attachment. [Means for solving the problem]

[0007] To solve the aforementioned conventional problems, the invention of claim 1 provides an attachment for a cleaning tool that connects a head member comprising a cleaning body and a base for holding the cleaning body, and a rod-shaped gripping handle provided with a pair of clamping bodies at its tip, wherein the attachment is substantially T-shaped and comprises an upper base having an upper surface, a lower surface and a pair of side surfaces, and a lower base extending perpendicularly to the lower surface at approximately the center of the longitudinal direction of the upper base, wherein the lower base has a fixing means at one end for connecting to the head member, the upper base has an upper groove formed along the longitudinal direction of the upper surface, and one or more pairs of lateral grooves formed along the longitudinal direction of each of the pair of side surfaces, and the gripping bodies of the gripping handle can be fitted into the upper groove and one of the lateral grooves, thereby fixing the gripping handle so that its longitudinal direction is at an angle to the extending direction of the lower base.

[0008] In the invention of claim 1, by forming an upper groove portion into which a pair of clamping bodies of the gripping handle are fitted, and one or more lateral groove portions on the upper base portion of the attachment, the longitudinal direction of the gripping handle can be fixed at an angle with respect to the extending direction of the lower base portion, and the mounting angle of the gripping handle to the cleaning body can be easily changed. Furthermore, since only one gripping handle and one attachment are required, the overall manufacturing cost of the cleaning tool can be reduced.

[0009] The invention of claim 2 is characterized in that, in the invention of claim 1, the gripping body of the gripping handle and the pair of lateral grooves of the upper base are fitted together so that the longitudinal direction of the gripping handle is substantially parallel to the extending direction of the lower base. This makes it easy to change between cases where the longitudinal direction of the gripping handle has an angle with respect to the extending direction of the lower base and cases where it does not.

[0010] The invention of claim 3 is characterized in that, in the invention of claim 1, the upper base portion has an inclined surface formed near the opening of the upper groove portion. This makes it possible to strengthen the fit with the clamping body provided on the gripping handle.

[0011] The invention of claim 4 is characterized in that, in the invention of claim 1, the upper base portion has an inclined surface formed near the opening of the lateral groove. This makes it possible to strengthen the fit with the clamping body provided on the gripping handle.

[0012] The invention of claim 5 is characterized in that, in the invention of claim 1, the upper base portion has inclined surfaces formed near the opening of the upper groove portion and near the opening of the lateral groove portion. This makes the fitting with the clamping body provided on the gripping handle even stronger.

[0013] The invention of claim 6 is characterized in that, in any of the inventions of claims 1 to 5, the upper groove of the upper base portion has a recess formed in a direction substantially perpendicular to the upper surface, and the lateral groove of the upper base portion has a recess formed in a direction substantially perpendicular to the side surface. This makes it possible to have a compact shape without increasing the size of the attachment.

[0014] The invention of claim 7 is characterized in that, in any of the inventions of claims 1 to 5, the upper groove of the upper base has a projection with a substantially triangular cross-section formed on its inner surface along the longitudinal direction of the upper groove. This makes it possible to firmly engage with the clamping body provided on the gripping handle with a simple structure, and also allows the gripping handle to be inclined and fixed to either of the two sides formed in the longitudinal direction of the upper groove.

[0015] The invention of claim 8 comprises a head member consisting of a cleaning body and a base for holding the cleaning body, a rod-shaped gripping handle provided with a pair of clamping bodies at its tip, and a connection between the head member and the gripping handle. Claim 1 A cleaning tool having an attachment for a cleaning tool is characterized in that the angle of inclination differs depending on whether the longitudinal direction of the gripping handle is fixed at an angle toward one side of the cleaning body or at an angle toward the other side of the cleaning body. This allows the user to select an appropriate angle of inclination according to their height, thereby reducing the strain on the arms and waist during use. Furthermore, the angle of inclination can be varied to correspond to the type of cleaning body placed on the side, thereby improving the cleaning effect.

[0016] The invention of claim 9 comprises a head member consisting of a cleaning body and a base for holding the cleaning body, a rod-shaped gripping handle provided with a pair of clamping bodies at its tip, and a connection between the head member and the gripping handle. Claim 1 A cleaning tool having an attachment for a cleaning tool, wherein the cleaning body is characterized in that a brush member is arranged on one side and a blade member is arranged on the other side. As a result, when the handle is tilted toward the brush member side, it is particularly effective for transporting dust and other particles on the floor surface, and when it is tilted toward the blade member side, it is particularly effective for transporting hair and other particles in carpets, allowing the cleaning member to be selected according to the usage environment and improving the cleaning effect.

[0017] The invention of claim 10 is characterized in that, in the invention of claim 8, the cleaning body has a brush member arranged on one side and a blade member arranged on the other side. This makes it possible to make the angle of inclination different when the brush member is arranged on the side on which the handle is tilted and when the blade member is arranged, thereby further improving the cleaning effect. [Effects of the Invention]

[0018] The invention of the attachment for a cleaning tool according to claim 1 can easily change the attachment angle of the gripping handle to the cleaning body. Also, it is possible to reduce the manufacturing cost of the entire cleaning tool. Further, the invention of claim 2 can easily perform the changing operation when the longitudinal direction of the gripping handle has an angle with respect to the extending direction of the lower base and when it has no angle. Also, the inventions of claims 3 to 5 can strengthen the fitting with the clamping body provided on the gripping handle.

[0019] The invention of claim 6 can achieve a compact shape without increasing the size of the attachment. Further, the invention of claim 7 can strengthen the fitting with the clamping body provided on the gripping handle with a simple structure, and can fix the gripping handle by inclining it to either side of both side surfaces formed in the longitudinal direction of the upper groove portion.

[0020] The invention of the cleaning tool according to claim 8 can select an appropriate inclination angle according to the user's height, so it can reduce the burden on the arm and waist during use, and can vary the inclination angle corresponding to the type of cleaning body arranged on the side surface, thereby improving the cleaning effect. Also, the invention of claim 9 can incline the gripping handle to the brush member side and the blade member side respectively, so the cleaning member can be selected according to the use environment, and the cleaning effect can be improved. Further, the invention of claim 10 can vary the inclination angle when the brush member is arranged on the side surface of the side where the gripping handle is inclined and when the blade member is arranged, and can further improve the cleaning effect.

Mode for Carrying Out the Invention

[0022] FIG. 1(a) is a perspective view showing the cleaning tool attachment according to the present invention as viewed from above, and FIG. 1(b) is a perspective view showing the attachment as viewed from below. Further, FIG. 2(a) is a front view showing the cleaning tool attachment according to the present invention, FIG. 2(b) is a side view thereof, and FIG. 2(c) is a cross-sectional view thereof. The details of the cleaning tool attachment according to the present invention will be described below using these figures. Note that the present invention is not limited by this embodiment.

[0023] The cleaning tool attachment 10 is an attachment 10 that connects a head member including a cleaning body described later and a base for holding the cleaning body, and a rod-shaped gripping handle provided with a pair of clamping bodies at the tip. It is formed in a substantially T-shaped configuration including an upper base 1 having an upper surface 1a, a lower surface 1b, and a pair of side surfaces 1c and 1d, and a lower base 2 extending in a direction perpendicular to the lower surface 1b at a substantially central position in the longitudinal direction of the upper base 1 on the lower surface 1b.

[0024] Further, the lower base 2 has through holes 2a and 2b constituting fixing means for connecting to the head member at one end. The upper base 1 has an upper groove portion 3 formed along the longitudinal direction of the upper surface 1a, and a pair or more of lateral groove portions are formed along the longitudinal direction of each of the pair of side surfaces 1c and 1d. In this embodiment, four pairs of lateral groove portions 4a, 4b, 4c, and 4d are formed, and the lateral groove portion 4d is formed on the lower surface 1b side of the upper base 1. Since the grooves are formed along the longitudinal direction of the pair of side surfaces 1c and 1d, they are included in the lateral groove portions in the claims.

[0025] As will be described later, the gripping body of the handle is fitted into one or more of the upper groove 3 and the lateral grooves 4a, 4b, 4c, and 4d, allowing the handle to be fixed so that its longitudinal direction is at an angle to the extension direction of the lower base. This makes it easy to change the mounting angle of the handle to the cleaning object. In addition, since only one handle and attachment are needed, the overall manufacturing cost of the cleaning tool can be reduced.

[0026] The upper base portion 1 has an inclined surface 5a near the opening of the upper groove portion 3, and an inclined surface 5b near the opening of the lateral groove portion. A part of the gripping body of the grip handle, which will be described later, will come into contact with these inclined surfaces 5a and 5b. This makes the fit with the gripping body provided on the grip handle stronger.

[0027] The upper groove 3 of the upper base 1 has a recess 6a formed in a direction approximately perpendicular to the upper surface 1a, and the lateral grooves 4a, 4b, and 4c of the upper base 1 have recesses 6b formed in a direction approximately perpendicular to the side surface 1c. This allows the attachment 10 to have a compact shape without becoming large.

[0028] The upper groove 3 of the upper base 1 has a projection 7 with a roughly triangular cross-section formed on its inner surface along the longitudinal direction of the upper groove 3. This allows for a strong fit with the gripping body provided on the gripping handle with a simple structure, and also allows the gripping handle to be fixed at an angle to either of the two sides 1c and 1d formed in the longitudinal direction of the upper groove 3.

[0029] Figure 3(a) is a side view showing the cleaning tool according to the present invention, and Figure 3(b) is an enlarged cross-sectional view of the same part. As shown in these figures, the cleaning tool 20 has a head member 11 consisting of a cleaning body 11a and a base 11b that holds the cleaning body 11a, a rod-shaped gripping handle 8 with a pair of clamping bodies 9a and 9b provided at its tip, and a cleaning tool attachment 10 that connects the head member 11 and the gripping handle 8. The pair of clamping bodies 9a and 9b of the gripping handle 8 and the pair of lateral grooves 4a, 4b, and 4c of the upper base 1 of the attachment 10 fit together, so that the longitudinal direction of the gripping handle 8 is fixed to be substantially parallel to the extending direction of the lower base 2. This makes it easy to change between when the longitudinal direction of the gripping handle 8 has an angle with respect to the extending direction of the lower base 2 and when it does not.

[0030] The cleaning body 11a has a brush member 12a on one side and a blade member 12d made of soft synthetic resin on the other side. Between the brush member 12a and the blade member 12d are brush members 12b and 12c, which have different bristle stiffness than brush member 12a. The bristle stiffness of brush members 12a, 12b, and 12c can be arranged such that the outer brush member 12a has the weakest bristle stiffness, and the inner brush member 12c has the strongest bristle stiffness. The cleaning body is not limited to brush members or blade members; any material that produces a cleaning effect, such as cloth or sponge, is included in this invention.

[0031] Furthermore, the lower base 2 of the cleaning tool attachment 10 has a fixing means at one end for connecting to the head member. The fixing means consists of through holes 2a and 2b (see Figures 1 and 2), a female screw 13a, a male screw 13b, and an O-ring 13c. The female screw 13a is inserted into the through hole 2b and the through hole formed in the base 11b of the head member 11, while the male screw 13b is inserted from the other through hole 2b. The head member 11 is fixed to the lower base 2 of the cleaning tool attachment 10 by screwing the female screw 13a and the male screw 13b together. At this time, the O-ring 13c, which is made of a soft material, is placed on the stepped portion formed on the edge of the through hole 2a, and the male screw 13b and the lower base 2 of the cleaning tool attachment 10 are pressed together via the O-ring 13c. In this way, the head member 11 is made rotatable around the male screw 13b and female screw 13a as its axis, relative to the lower base 2 of the cleaning tool attachment 10.

[0032] Figure 4(a) is a side view showing the cleaning tool according to the present invention, and Figure 4(b) is an enlarged cross-sectional view of the same part. As shown in these figures, the cleaning tool 20 has one end of the pair of clamping bodies 9a and 9b of the gripping handle 8 inserted and fixed into a recess 6a formed in the upper groove 3, and the other end of the clamping body 9a inserted and fixed into a recess 6c formed in the lateral groove 4d. As a result, the longitudinal direction of the gripping handle 8 can be fixed to have an inclination angle X with respect to the extension direction of the lower base 2.

[0033] The effects of using the cleaning tool 20 shown in Figures 4(a) and 4(b) will be explained. Conventional cleaning tools such as brooms, mops, and scrapers are designed so that the longitudinal direction of the handle is approximately parallel to the protruding direction of the cleaning body (the state shown in Figure 3(a)). The user holds the handle and uses a snap of the wrist or rotation of the shoulder and elbow to slide the tip of the cleaning body against the surface to be cleaned. However, this motion puts a strain on the wrist, shoulder, and elbow, and it is difficult to move the entire tip of the cleaning body, which has a high cleaning effect, while keeping it in contact with the surface to be cleaned, resulting in poor cleaning efficiency. The cleaning tool 20 allows the user to efficiently transfer dust and dirt and remove grime with a simple motion of holding the handle 8 and moving it back and forth (left and right in Figure 4(a)). Furthermore, since there is no need to flick the wrist or rotate the shoulder or elbow, the workload on the user is reduced. In addition, because the cleaning body 11a does not tilt excessively or lift up relative to the surface to be cleaned, the entire tip of the cleaning body can be moved while in contact with the surface to be cleaned, thereby improving the cleaning effect.

[0034] Figure 5(a) is a side view showing the cleaning tool according to the present invention, and Figure 5(b) is an enlarged cross-sectional view of the same part. As shown in these figures, the cleaning tool 20 has one end of the pair of clamping bodies 9a and 9b of the gripping handle 8 inserted and fixed into a recess 6a formed in the upper groove 3, and the other end of the clamping body 9b inserted and fixed into a recess 6c formed in the lateral groove 4d. As a result, the longitudinal direction of the gripping handle 8 can be fixed to have an inclination angle X with respect to the extension direction of the lower base 2.

[0035] The effects of using the cleaning tool 20 shown in Figures 5(a) and (b) will be explained below. Effects similar to those when using Figures 4(a) and (b) will be omitted. When using the cleaning tool 20, the user stands on the inclined side of the handle 8 (right side in Figure 5(a)) and, facing the cleaning tool 20, repeatedly pulls the cleaning tool 20 from back to front, sliding the cleaning body 11a on the surface to be cleaned. Alternatively, facing away from the cleaning tool 20, the user holds the handle 8 and slides the cleaning body 11a on the surface to be cleaned by moving forward (right side in Figure 5(a)). Since the blade member 12d is positioned on the sliding direction side of the cleaning body 11a, it can be used particularly effectively for tasks that are difficult to handle with brush members 12a, 12b, and 12c, such as moving hair in carpets or removing water from floor surfaces. On the other hand, when used in the state shown in Figure 4(a), the brush members 12a, 12b, and 12c are positioned on the sliding direction side, making it particularly effective for transporting dust and other particles from the floor surface.

[0036] Furthermore, the cleaning tool 20 according to the present invention allows users to appropriately select the states shown in Figures 3(a) and (b), Figures 4(a) and (b), and Figures 5(a) and (b) according to the cleaning environment. It is also possible to easily change between cases where the longitudinal direction of the gripping handle 8 has an angle with respect to the extension direction of the lower base 2 and cases where it does not, thereby improving cleaning efficiency.

[0037] Figure 6(a) is a side view showing another embodiment of the cleaning tool according to the present invention, and Figure 6(b) is an enlarged cross-sectional view of the same part. In this embodiment, the shapes of the upper groove 33, lateral groove 34, and inclined surfaces 35a and 35b of the attachment 30 are modified so that the inclination angle Y is greater than the inclination angle X when compared to the state shown in Figures 4(a) and (b). On the other hand, when the grip handle of the cleaning tool 40 is inclined to the opposite side, the inclination angle is the same as the state shown in Figures 5(a) and (b). The shapes of the upper groove 33, lateral groove 34, and inclined surfaces 35a and 35b of the attachment 30 are modified so that the inclination angle differs depending on whether the longitudinal direction of the grip handle is fixed inclined to one side of the cleaning body or to the other side of the cleaning body. This makes it possible to vary the inclination angle according to the type of cleaning body placed on the side, thereby improving the cleaning effect. In addition, since the inclination angle of the grip handle can be selected according to the user's height, the burden on the arms and waist during use can be reduced.

[0038] In Figures 6(a) and (b), the cleaning body 11a has a brush member 12a on one side and a blade member 12d on the other side. The design ensures that the angle of inclination is greater when the handle 8 is tilted towards the side of the brush member 12a compared to when it is tilted towards the side of the blade member 12d. This is because the center of gravity is positioned further forward, allowing the brush member to press more strongly against the surface being cleaned, thereby improving the cleaning effect. [Industrial applicability]

[0039] The cleaning tool attachment and cleaning tool according to the present invention connect a head member consisting of a cleaning body and a base for holding the cleaning body, and a rod-shaped gripping handle provided with a pair of clamping bodies at its tip, and are used as a cleaning tool equipped with this cleaning tool attachment.
