Description: DESCRIPTION HANDY MOP BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a handy mop which can be used for cleaning operation to remove dust in a room, car or the like. Description of the Related Art The handy mop of this type is generally constructed by attaching a mop body to a handle for use. Such a mop body used to be of a reusable type that can be washed after stained. However, in recent years, a disposable type of mop body has become to be widely used in combination with a handle to which the disposable mop body is attached. In the above-mentioned conventional handy mop which is composed of the disposable mop body and the handle to which the disposable mop body is attached, the mop body, after insertion of the solid handle, is clamped on the handle by means of spring or fixed on the handle by means of a rubber molded component, thereby preventing the mop body from being detached from handle during use. However, such means for preventing detachment of the mop body during use causes trouble in attachment and detachment of the mop body, in addition, since the attachment portion of the handle to which the mop body is attached is of stick shape, it may cause damages when comes into contact with furniture or the like during cleaning operation. SUMMARY OF THE INVENTION The present invention has been worked out in view of the shortcoming in the prior art set forth above. It is therefore an object of the present invention to provide a handy mop, which hardly causes damages during cleaning operation, and which permits simple attachment and detachment of a mop body while preventing detachment of the mop body during use. According to the present invention, there is provided a handy mop comprising a mop body for collecting dust and a handle to which the mop body is to be attached, the mop body being provided with two gaps extending in parallel for attachment of the handle thereto, the handle being, provided with an attachment portion and a gripper extending rearwardly upwardly from a root end of the attachment portion, the attachment portion being bifurcated at the root end to provide two insert plates, which are flat and level, and are to be inserted into the gaps of the mop body for use. Preferably, a leading end of each insert plate is rounded off. Preferably, the handle is further provided with a clamping plate projecting from the root end of the attachment portion in between the two insert plates, a leading end of the clamping plate being upwardly inclined, the clamping plate being provided on a bottom surface thereof with a catch portion. Preferably, each insert plate is provided on an edge thereof with at least one protrusion. In this case, preferably, each gap of the mop body is provided with a widened region for accommodating the protrusion of each insert plate of the handle.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention will be discussed hereinafter in detail in terms of the preferred embodiment of a handy mop according to the present invention with reference to the accompanying drawings . In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be obvious, however, to those skilled in the art that the present invention may be practiced without these specific details. In other instance, well-known structures are not shown in detail in order to avoid unnecessary obscurity of the present invention. Fig.1 is a perspective view showing a handy mop according to one embodiment of the present invention. The handy mop shown in Fig. 1 is composed of a mop body 10 and a handle 20 to which the mop body 10 is to be attached. The mop body 10 comprises two or three fluffed nonwoven fabrics made of synthetic resin, which are stacked one on another and are then welded on lines extending across the mop body 10. The mop body 10 is further provided at its upper side with another nonwoven fabric shorter than the stacked nonwoven fabrics. As shown in Fig. 1, the shorter nonwoven fabric is laid on the center portion of the stacked nonwoven fabrics and welded thereto on three lines " a" extending in a longitudinal direction of the mop body 10. These three weld lines " a" define two parallel gaps " b" for attachment therebetween. As shown in Fig. 2, the handle 20 is composed of an attachment portion 30 which is made of synthetic resin, and a gripper 40 which is likewise made of synthetic resin and is to be fixed to the root end of the attachment portion 30 by fit. Of these, the attachment portion 30 is bifurcated at its root end to provide two insert plates 31, which are flat and level, as shown in Figs. 3A, 3B and 3C. The thickness of the insert plates 31 may be determined in accordance with their length so that the insert plates 31 may cause appropriate resilient flexure upon receiving pressure. On the other hand, as shown in Figs. 4A, 4B and 4C, the gripper 40 is of a shape to extend rearwardly and upwardly from the root end of the attachment portion 30 when it fits on the attachment portion 30. From the point of view of handleability, the length of the gripper 40 as viewed in plan configuration is preferably 10 to 20 cm or so. Both the attachment portion 30 and the gripper 40 are preferably made of polypropylene. The leading end of each insert plate 31 of the attachment portion 30 is rounded off (i.e., curved). Preferably, the leading end is curved not only in plan configuration but also in vertical section configuration. In consideration of easy insertion of the insert plates 31 into gaps " b" of the mop body 10, the leading end is preferably curved in vertical section configuration such that the radius of curvature on the upper side thereof is much larger than that on the lower side thereof. Moreover, each insert plate 31 is provided at its outer edge with two arcuate protrusions 32. These protrusions 32 come into contact with the weld lines " a" upon insertion of the inert plates 31, thereby serving as stopper. Here, the number and location of the protrusions 32 may be appropriately selected in consideration of the effect of preventing detachment and easy insertion, as long as each insert plate 31 has at least one protrusion 32 at either of the outer edge and the inner edge. The handle 20 is further provided with a clamping plate 33 projecting from the root end of the attachment portion 30 in between the two insert plates 31. The leading end of the clamping plate 33 is upwardly inclined, and the clamping plate 33 is provided on its bottom surface with a catch portion 33a. The root end of the attachment portion 30 has a semicircular thin portion 35, which is enclosed by a flange 34 on the top surface of the root end and is formed with a cut-out 36. On the other hand, the gripper 40 is provided at the leading end of a grip portion 41 with a fitting structure composed of an upper plate portion 42 and a lower plate portion 43. When the thin portion 35 of the attachment portion 30 is inserted in between the plate portions 42 and 43 of the gripper 40, a connecting portion 44 between the plate portions 42 and 43 mates with the cut-out 36, and in conjunction therewith, a groove 42a formed in the lower surface of the upper plate portion 42 mates with a protrusion 35a of the thin portion 35, so that the attachment portion 30 is fixed to the gripper 40. The handy mop having the above-described construction is assembled for use into a state shown in Fig.1, by assembling the handle 20 from the attachment portion 30 and the gripper 40 and by attaching the mop body 10 to the handle 20 thus assembled. For attaching the mop body 10 to the handle 20, the insert plates 31 of the attachment portion 30 are inserted into the gaps " b" disposed on the upper side of the mop body 10. Here, the insert plates 31 may be inserted into the gaps " b" from either side of the mop body 10. In the course of insertion, the protrusions 32 of the insert plates 31 are brought into contact with the outside weld lines " a" , and lastly, the clamping plate 33 disposed between the insert plates 31 runs upon the central weld line " a" . Thus, the attachment is completed in such a state as in Fig.5. In this attached state, since the protrusions 32 of the insert plates 31 are kept in contact with the outside weld lines " a" and the clamping plate 33 has the catch portion 33a on its bottom surface, the detachment of the mop body 10 from the handle 20 can be effectively prevented. Figs. 6A and 6B are illustrations showing a state where other types of mop body having widened regions formed in gaps are attached to the handle. Fig. 6A shows the case where the weld lines " a" are bulged convexly outwardly at locations corresponding to the protrusions 32 of the insert plates 31. On the other hand, Fig. 6B shows the case where the weld lines " a" are interrupted at locations corresponding to the protrusions 32 of the insert plates 31. With the widened regions thus formed in the gaps for insertion, the protrusions 32 of the insert plates 31 in an attached state mate with the bulged portions or interrupted portions of the weld lines " a" , as shown in Fig. 6A or 6B, which prevents detachment of the mop body 10 more effectively. Although the present invention has been described in detail with respect to exemplary embodiment thereof, the handy mop of the present invention should not be understood as limited to the specific embodiment set out above but various changes may be made therein, without departing from the spirit of the present invention. For example, the mop body may be of any type as long as it has two gaps for attachment. Although the handle of the above-described embodiment is composed of two components of fitting type so as to make the handle compact when it is not used, it may, of course, be possible that the handle is composed of a single component. As a result of the various structures described in detail above, advantages of the invention may include one or more of the following: ( 1 ) The mop body is hardly detached from the handle during use but can be attached to or detached from the handle by a single operation; (2) The flat insert plates to which the mop body is attached cause resilient flexure upon receiving pressure so that they do not damage an object to be cleaned; (3) In case where the leading end of each insert plate is rounded off, the insert plates can be smoothly inserted into the gaps of the mop body without being caught therein; (4) In case where the handle is provided with the clamping plate projecting from the root end of the attachment portion in between the two insert plates, the leading end of the clamping plate is upwardly inclined, and the clamping plate is provided on the bottom surface thereof with the catch portion, when the insert plates are inserted into the gaps of the mop body, the clamping plate between the insert plates runs upon the central weld line, pressing the mop body to maintain it in an attached state, which prevents detachment of the mop body more effectively; (5) In case where each insert plate is provided on the edge thereof with at least one protrusion, when the insert plates are inserted into the gaps of the mop body, the protrusions of the insert plates come into contact with the outside weld lines, which prevents detachment of the mop body more effectively; and (6) In case where each gap of the mop body is provided with the widened region for accommodating the protrusion of each insert plate of the handle, when the insert plates are inserted into the gaps of the mop body, the protrusions of the insert plates mate with the widened regions, which prevents detachment of the mop body more effectively.
