[Background Art and Problems to be Solved by the Invention]

 In general, dust has a configuration in which a long handle is connected to a dust removing body that sweeps and accommodates dust and dirt. That is, a handle is attached to facilitate the operation of the dusting body and facilitate the work. Usually, the above-mentioned design is connected directly to the above-mentioned dusting body using a rivet or a screw, or via a predetermined member. It is performed.

[0003] Therefore, dusting with the above configuration is inconvenient because it must be handled in a bulky state with a handle attached to it during shipping and transportation, and is disadvantageous in terms of transportation efficiency and cost. . In addition, problems such as requiring a large display space also occur when displaying at a store. In addition, the buyer of the dustpan must bring the bulk dustpan home, which is inconvenient.

[0004] For this reason, it is conceivable to ship and transport from a factory or the like without the handle attached, attach the handle before displaying at the store, or attach the handle at home or the like. . However, the work of attaching the handle using rivets, screws, etc. is extremely complicated and burdens the store or the purchaser.

[0005] Further, when a handle is connected using a rivet or a screw, stress tends to concentrate on a mounting portion of the rivet or the screw. For this reason, if the above dusting is used repeatedly, the mounting portion will be damaged, and eventually the handle will come off. As described above, in connecting the handle using rivets, screws, or the like, there is not a small problem in terms of the mounting strength of the handle.

The present invention was devised in view of the above circumstances, and provides a dustpan on which a handle can be easily and easily attached, and a joint that can be suitably used for this dustpan. Is the task.

[0007]

[Disclosure of Invention]

 In order to solve the above problems, the present invention takes the following technical measures.

That is, according to the first aspect of the present invention, a bar-shaped member is connected to a predetermined member having a uniform cross section and extending in a longitudinal direction so as to extend in a direction orthogonal to the predetermined member. A first engagement portion is formed at a portion from an end in a longitudinal direction, and a base is connected to the predetermined member in a posture in contact with the predetermined member; and A substantially T-shaped joint body extending from a central portion and having a connection portion connected to the rod-shaped member, a second engagement portion engaging with the first engagement portion are formed, and are formed in a cylindrical shape. A slider formed so as to be capable of sliding movement by enclosing the predetermined member, and wherein the slider engages the first engaging portion in a state where the slider sandwiches the end of the base and the predetermined member. And the second engagement portion A joint is provided, wherein the joint is configured so as to restrain the base and the predetermined member by engaging with each other and attach the joint body to the predetermined member.

When the bar-shaped member is attached so as to extend upward from the predetermined member using the joint, the predetermined member is placed in a state where the predetermined member is covered from above by the base of the joint main body. All that is required is to slide the slider toward the connection portion of the joint body. When the slider thus moved reaches the mounting position of the joint main body, not only the above-mentioned predetermined member but also the base is wrapped by the slider. Then, when the slider is further moved to the connection portion side, the first engagement portion of the base engages with the second engagement portion of the slider. In this state, the base (joint body) and the slider are connected, and the end of the base and the predetermined member are sandwiched in the slider. Is restrained by the slider together with the predetermined member.

As described above, the joint according to the invention of the present application is mounted such that the base of the joint main body is placed so as to cover a predetermined member, and the slider is moved to engage the engaging portions. The rod member can be connected to the predetermined member by the operation. In addition, since the rod-shaped member is connected to the predetermined member without using any rivets or screws, stress concentrates on the portion where the rivet or screw is attached as in the conventional case, and the mounting portion of each of the above members is attached. Can be maintained in a good connected state without being damaged.

Of course, the rod-shaped member may be connected to the connecting portion of the joint body in advance, or may be connected after the joint body is attached to a predetermined member. Further, the joint body may be attached to the predetermined member by one slider, but it is preferable to restrain each of both ends of the base by two sliders. The first engaging portion may be formed in a projecting shape, and the second engaging portion may be formed in a recessed or penetrating shape so that the engaging portions are engaged with each other. The first engaging portion may be recessed or penetrating, and the second engaging portion may be projecting so that the engaging portions engage with each other.

According to a second aspect of the present invention, the arm member attached to the dusting body and the longitudinal handle are connected to each other through a joint to form a flat end, and the longitudinal end is provided. A first engaging portion is formed at a portion of the base portion, the base portion is connected to the arm member in a posture in contact with the arm member, and a base extending from a central portion of the base portion and connected to the handle. A substantially T-shaped joint body having a connecting portion, and a second engaging portion that engages with the first engaging portion are formed, and are formed in a cylindrical shape and enclose the arm member. A slider that is slidable and engages the first engagement portion and the second engagement portion in a state where the slider sandwiches the end of the base and the arm member. By combining, the above base and the above A dusting device is provided which is configured to restrain the arm member and connect the joint body to the arm member.

In the dusting of the above configuration, a joint having substantially the same configuration as the joint described in detail in the first aspect is used. In other words, the dust removal on the side surface can be performed simply by placing the base of the joint body so as to cover a predetermined portion of the arm member, and moving the slider to engage the engaging portions. The handle can be connected to the arm member by an operation. That is, the handle can be easily connected to the dusting body. Moreover, since no rivets or screws are used when attaching the handle, stress concentrates on the parts where the rivets or screws are attached as in the past, and the attachment parts of the above members are damaged, and the handle is damaged. The state in which the handle is properly attached can be maintained without coming off.

[0014] As described above, in the above-described dusting, since the handle is easily attached, the handle is shipped from a factory or the like in a state where the handle is separated in order to improve handling convenience and reduce transportation costs. -Even when transported, there is no problem as before. In other words, even if the dustpan is displayed and sold at the store with the patterned body attached, the burden on the store side required to attach the patterned body is not so large, and the dust is removed with the patterned body separated. Even if the buyer who displays and sells the dust and installs the pattern at home, the burden on the buyer is small. Therefore, even if dust is distributed while the pattern is separated, the pattern is connected to the main body using conventional rivets or bolts, and the burden on the store or the purchaser is much greater than in the case of dust removal. Has been reduced.

According to a preferred embodiment, the first engaging portion formed on the joint main body or the second engaging portion formed on the slider can be vertically displaced.

For example, considering the case where the first engagement portion of the joint body has a projection and the second engagement portion of the slider has a through hole, the slider is moved. If each of the engagement portions is engaged by moving the projection, the projection interferes with the base of the joint body until the projection is engaged with the through-hole, and this causes a resistance when the slider moves. It is concerned that That is, the slider cannot be moved smoothly due to the movement resistance, and it may not be easy to engage the protrusion with the through hole. In such a case, if the protrusion (the first engaging portion) or the through hole (the second engaging portion) can be displaced vertically, the protrusion interferes with the base of the joint body. However, the displacement of the protrusions or the through holes can reduce the movement resistance. Therefore, if the first engagement portion or the second engagement portion is vertically displaceable as in the above configuration, the slider can be moved smoothly, and the respective engagement portions can be moved smoothly. The operation of engaging each other becomes easier.

According to a preferred embodiment, the base of the joint body and the arm member are further provided with positioning means for attaching the joint body to a desired position of the arm member.

According to the above configuration, since the base and the arm member are provided with the positioning means, the handle can be easily and reliably connected to a desired position of the arm member. In addition, the positioning means may be configured as, for example, a projection formed at the base of the joint body and a through hole formed at the arm member, or conversely, a through hole formed at the base. It can be configured as a projection formed on the arm member. In the case where the positioning means is constituted by the projection and the through hole, the projection is engaged with or fitted to the through hole when the joint body is attached to the arm member. Thus, a good attachment state of the joint body and a good connection state of the handle can be maintained.

Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

As shown in FIGS. 3 and 4, the arm member 23 is formed in a bent U-shape, and a handle 25 described later is provided at the center thereof through the joint 3. The positioning hole 23b used when connecting by connecting is formed. Also, as shown in FIGS. 1 to 3, both ends of the arm member 23 are rotatably attached to the dusting body 20 and, as described above, rotate with the lid 22 at an appropriate portion thereof. It is movably connected. The connection between the arm member 23 and the dust removing main body 20 or the connection between the arm member 23 and the lid body 22 is performed by appropriate means using, for example, rivets.

As shown in FIGS. 3 to 5, a handle 25 made of a hollow pipe material is connected to the arm member 23 via a joint 24, and the other end of the handle 25 is A handle 26 is provided for facilitating the operation of the dusting 2.

In the dust removing device 2 configured as described above, the dust removing body 20 stands by the weight of the dust removing body 20 only by lifting the handle 26, and at this time, the arm member 23 is attached to the dust removing body 20. It relatively rotates with respect to it. Along with this, the lid 22 slides on the upper surface of the dust removing main body 20 and closes the open portion of the dust removing main body 20.

As shown in FIGS. 4 and 5, the joint 3 includes a joint body 30 connected to the arm member 23 in a posture covering the arm member 23 and a sliding movement including the arm member. And a pair of sliders 31 and 31 that can be used.

The joint main body 30 includes a base 30 a that is in contact with the arm member 23, and a connecting portion 30 b that extends upward from a central portion of the base and has a columnar shape as a whole. The base 30a has a rectangular shape in a plan view, and the rear surface has a shape corresponding to the surface shape of the arm member 23 so that the base 30a comes into contact with the arm member 23 exactly. The base 30a has through-holes 30c, 30c as first engagement portions formed at both ends in the longitudinal direction, and positioning projections 30d as positioning means projecting from the back surface thereof.

The handle 25 can be connected to the arm member 23 by a simple operation such as engaging the joints 30c and 31a. Moreover, since the handle 25 is attached to the arm member 23 without using any rivets or screws, stress is concentrated on the portion where the rivets or screws are attached as in the conventional case, and the mounting portion of each of the above members is attached. The handle 25 is not damaged and the handle 25 does not come off, and the state in which the handle is properly attached can be maintained.

Further, in the above-mentioned dust removal 2, since the handle 25 is easily attached, the handle 25 is shipped from a factory or the like in a state where the handle 25 is separated in order to facilitate handling and reduce transportation costs. Even if it is transported, the conventional trouble does not occur. In other words, even if the dust is displayed and sold in a state where the pattern 25 is attached at the store, the burden on the store required to attach the pattern 25 is not so large, and the pattern 25 is separated. Even if the dustpan is displayed and sold in a state where the dustpan is installed, and the buyer of the dustpan attaches the pattern 25 at home or the like, the burden on the purchaser is small. Therefore, even if the dust is distributed while the pattern 25 is separated, the pattern is connected to the dust body using conventional rivets or bolts, and the shop side or the purchase is much more remarkable than the conventional method. The burden on people is reduced.

In the above embodiment, the first engaging portion is the through hole 30c, and the second engaging portion 31a has the projection 31b. May have a projection, the second engagement portion may be a through hole, and the first engagement portion may be vertically displaceable.
