[0020] The objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. It should be noted that in assigning reference numerals to the components of each drawing in this specification, identical components are assigned the same number whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the invention.

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0023] FIG. 1 is a drawing of a mop according to a first embodiment of the present invention, FIG. 2 is a drawing showing a fixing ring of the mop according to the first embodiment of the invention coupled to the front side of the main body, and FIG. 3 is a drawing showing a structure in which the main body and the fixing ring of the mop according to the first embodiment of the present invention are coupled. In addition, FIG. 4 (a) and (b) are drawings showing cross-sections cut in the directions A-A', B-B', C-C', I-I', HH', and G-G' of the part where the main body and the fixing ring of FIG. 3 are coupled, FIG. 5 (a) and (b) are drawings showing cross-sections cut in the directions D-D', E-E', F-F', L-L', K-K', and J-J' of the part where the main body and the fixing ring of FIG. 3 are coupled, and FIG. 6 (a), (b), and (c) are drawings sequentially showing a cleaning cloth being fitted onto the mop according to the first embodiment of the present invention.

[0025] Referring to FIGS. 1 to 6, a mop (1) according to the first embodiment of the present invention is for cleaning and includes a cleaning cloth (70) attached thereto, a handle rod (10), a main body (20), and a fixing ring (30).

[0027] First, the cleaning cloth (70) is used to wipe away contaminants and can be formed from a sheet such as non-woven fabric, and depending on the implementation, a wet mop or various sheets may be used. In addition, the cleaning cloth (70) is used while attached to the mop (1), and a cleaning cloth (70) of a suitable size corresponding to the size of the main body (20) of the mop (1) may be used.

[0028] The handle rod (10) may have a bar-shaped structure, and the part held by the user may rotate so that the main body (20) can move freely. Additionally, the handle rod (10) may have a fixing groove (10h) provided on one side, and depending on the implementation, may perform the function of fixing or separating the fixing ring (30) from the fixing groove (10h).

[0029] The main body (20) is connected to the tip of the handle rod (10), and the connected part is rotatable, allowing the user to move the main body flexibly. Additionally, a plurality of recessed grooves (20h) may be formed around the circumference of the main body (20). Furthermore, although the main body (20) has a rectangular structure, it can be provided in various shapes, and the recessed grooves (20h) may be continuously formed along the circumference of the rectangular shape.

[0030] The recessed groove (20h) of the main body (20) is a structure that is concavely carved inward, and can be formed at a position corresponding to the fixing ring (30) so that the fixing ring (30) can be inserted and fitted. Additionally, the recessed groove (20h) can be provided in a semicircular concave shape as illustrated, and can be formed in a semicircular shape so that the fixing ring (30) can be inserted, rotate, and stably coupled. However, the present invention is not limited to a semicircular shape for the recessed groove (20h), and any shape other than a semicircular shape can be adopted as long as the fixing ring (30) can be inserted and fitted.

[0031] The recessed groove (20h) can be fitted and coupled with the fixing ring (30) and can be implemented in a form that is continuously formed along the circumference of the main body (20) and has a variable depth.

[0032] Specifically, the recessed groove (20h) of the main body (20) may include a first recessed groove (21h) into which the point with the maximum thickness of the cross-section of the fixing ring (30) is inserted, and a second recessed groove (22h) into which the point with the maximum thickness of the cross-section of the fixing ring (30) is located on the outside.

[0033] The fixing ring (30) can be fitted into the recessed groove (20h) of the main body (20) to perform the function of fixing the cleaning cloth (70). The fixing ring (30) is formed to be narrower than the diameter of the recessed groove (20h) and is fitted into the recessed groove (20h) at a position corresponding to the recessed groove (20h). To this end, the fixing ring (30) may be formed from a material containing elasticity, such as silicone, plastic, or metal. However, the material of the fixing ring (30) is not limited to these, and any material other than silicone, plastic, or metal that contains some elasticity and fixing power may be selected and used.

[0034] Additionally, the fixed ring (30) can be formed in multiple numbers depending on the implementation, and it is possible to modify it in various ways rather than in the shape of a ring.

[0036] Meanwhile, in order to explain in detail the part where the main body (20) and the fixing ring (30) are combined, which is a feature of the present invention, the direction is set and explained. The x-axis direction of the push rod (1) is called the major axis direction and the y-axis direction is called the minor axis direction. When the handle rod (10) is raised so that it goes upward, the direction along the z-axis is referred to as the upper side and the opposite side is referred to as the lower side.

[0038] Referring to (a), (b), and (c) of FIGS. 4 to 6, the recessed groove (20h) of the main body (20) is provided in a continuously concave shape along the circumference of the main body (20), and the height of the recessed groove (20h) can be provided in a variable shape such that it becomes flat, lower, and then flat again. Specifically, the recessed groove (20h) can be provided as a first recessed groove (21h) in which the point of maximum thickness of the cross-section of the fixing ring (30) is inserted inward, and a second recessed groove (22h) in which the point of maximum thickness of the cross-section of the fixing ring (30) is located outward. Additionally, the fixing ring (30) can be completely connected and coupled to the first recessed groove (21h), and only a part of the fixing ring (30) can be fitted into the second recessed groove (22h).

[0039] Specifically, when the pusher (1) of FIG. 3 is cut in the directions A-A', B-B', C-C', I-I', HH', and GG' and the cut cross-sections are examined, it can be seen that the fixing ring (30) is fully connected to the first recessed groove (21h), but only partially connected to the second recessed groove (22h).

[0040] To explain in detail, in AA' and C-C' of FIG. 4 (a), the fixing ring (30) is completely fitted into the first recessed groove (21h) of the main body (20), but when looking at B-B' of FIG. 4 (a), it can be seen that the fixing ring (30) is not completely fitted into the second recessed groove (22h). In addition, I-I', HH', and G-G', which are located in positions symmetrical to A-A', BB', and C-C' in the horizontal direction, can also be formed in the same way as above.

[0041] In addition, if you look at the cross-sections cut by cutting the pusher (1) of Fig. 3 in the directions D-D', E-E', F-F', L-L', K-K', and J-J' respectively, you can see that the fixing ring (30) is completely connected to the first recessed groove (21h).

[0042] In this way, the structure may be formed such that the fixing ring (30) is only partially connected to the main body (20) in A-A', B-B', C-C', I-I', HH', and G-G', and the fixing ring (30) is fully connected in D-D', E-E', F-F', L-L', K-K', and J-J'.

[0043] Additionally, the fixing ring (30) can be fully attached to the left side (A-A', B-B' and C-C') of the main body (20) relative to the handle rod (10), and the fixing ring (30) can be removed from the right side (I-I', HH' and G-G'), which is the opposite direction of the attached part.

[0044] Conversely, the fixing ring (30) located on the right side (I-I', HH' and G-G') of the main body (20) can be fully connected, and the fixing ring (30) located on the left side (A-A', B-B' and C-C') can be removed.

[0045] In this way, a structure is implemented in which a part of the main body (20) of the mop is completely connected to the fixing ring (30) and the opposite part is completely detached, thereby allowing the user to easily detach the fixing ring (30) from the main body (20) to remove or attach the cleaning cloth (70).

[0046] For example, when a user fully attaches the fixing rings (30) located at A, B, and C to the main body (20) and lifts the fixing rings (30) located at I, H, and G in the direction of the handle rod (10) to remove the fixing rings (30) located at I, H, and G, the fixing rings (30) located at I, H, and G are completely removed from the first recessed groove (21h) and the second recessed groove (22h), and the fixing rings (30) located at D, E, F, L, K, and J can also be naturally removed.

[0047] Conversely, the fixed ring (30) located at I, H, and G and the main body (20) are combined, and when the fixed ring (30) located at A, B, and C is removed, the fixed ring (30) located at D, E, F, L, K, and J can also be naturally removed from the main body (20).

[0048] At this time, the cleaning cloth (70) is inserted into the space between D, E, F, L, K, and J of the main body (20), and then A, B, and C become the rotation axis and the cleaning cloth (70) is inserted into the recessed groove (20h) of the main body (20) through I, H, and G, and then the fixing ring (30) is pressed. As illustrated in FIG. 6 (a), (b), and (c), the cleaning cloth (70) and the fixing ring (30) will be inserted into the first recessed groove (21h).

[0049] Through this structure, the user can easily remove or attach the cleaning cloth (70) by implementing a structure in which the fixing ring (30) located in the recessed groove (20h) is attached at once.

[0050] Meanwhile, as shown in FIG. 4 (a) and (b), the fixing ring (30) coupled to the second recessed groove is not fully fitted and coupled, but is formed in a structure that is fitted and coupled only to the first recessed groove (21h), so that a structure can be implemented that allows the user to easily and conveniently remove or attach the fixing ring (30) from the main body (20).

[0052] Meanwhile, the fixing ring (30) may be configured to be detachable from some of the multiple recessed grooves (20h) so as to be hinge-rotated in a first direction, detachable from other of the multiple recessed grooves (20h) so as to be hinge-rotated in a second direction, or detachable from the multiple recessed grooves (20h). Specifically, if the left side is referred to as the one side and the right side as the other side relative to the handle rod (10), the recessed groove (20h) and the fixing ring (30) are fixedly connected on the one side, but the other side can be completely detached. Additionally, the fixing ring (30) located on the other side can be rotated in the direction of the handle rod (10) by utilizing the round shape formed by the connection of the recessed groove (20h) and the fixing ring (30) located on the one side. Conversely, by completely attaching the fixing ring (30) to the recessed groove (20h) located on the other side and completely removing the fixing ring (30) located on one side, a structure that can rotate in the direction of the handle rod (10) can be implemented.

[0053] Additionally, depending on the implementation, as shown in FIG. 2, the fixing ring (30) may be connected only in the long axis direction of the main body and may be hinge-rotated. Specifically, if the direction in which the user pushes the push rod with respect to the handle rod (10) is referred to as the front (long axis direction from C-C' to G-G') and the opposite direction of the front is referred to as the rear (long axis direction from A-A' to I-I'), a structure can be implemented in which the recessed groove (20h) of the main body located in the front and the fixing ring (30) can be completely connected and the recessed groove (20h) of the main body located in the rear and the fixing ring (30) can be completely detached, thereby providing a structure that can be hinge-rotated.

[0055] In this way, the present invention is implemented with a structure that allows the fixing ring (30) to be attached or removed from the main body (20) in any direction, left, right, front, or rear relative to the handle rod (10), and since the hinge can rotate, the user can easily attach and detach the fixing ring (30) in any direction, and through a structure that allows the fixing ring (30) to be easily removed from the main body (20), the installation and removal of the cleaning cloth (70) is easy and convenient.

[0057] The following description will focus on the differences between this embodiment and other embodiments, and any parts omitted will be replaced by the preceding content.

[0059] FIGS. 7 to 9 are drawings of a pusher according to a second embodiment of the present invention, and FIG. 10 is a drawing roughly illustrating the structure in which a handle rod and a fixing ring of a pusher according to the second embodiment of the present invention are combined. The following description will be explained with reference to these figures.

[0061] Referring to FIGS. 7 to 10, the fixing rings (30) according to the second embodiment of the present invention are provided in a plurality and may be provided on one side and the other side respectively with respect to the handle rod (10). In addition, a plurality of recessed grooves (20h) may be formed on one side and the other side with respect to the handle rod (10) in correspondence with the position of each fixing ring (30).

[0062] Specifically, in the recessed groove (20h) of the main body (20) according to the second embodiment, a first recessed groove (21h) and a second recessed groove (22h) for inserting or withdrawing the fixing ring (30) may be located on one side relative to the handle rod (10). As described in the first embodiment, the first recessed groove (21h) is a groove into which the point with the maximum thickness of the cross-section of the fixing ring (30) is inserted, and the second recessed groove (22h) is a groove into which the point with the maximum thickness of the fixing ring (30) is located on the outside. Additionally, a recessed groove (20h) of the same shape as the one side may be formed on the other side relative to the handle rod (10).

[0063] Meanwhile, a plurality of fixing rings (30) can be formed with the same circumference and are positioned on one side and the other side of the main body (20), respectively, and can be fixedly coupled to the main body (20) on the one side and the other side.

[0064] Additionally, the fixing rings (30) of the pusher are provided in multiple numbers and can be positioned on one side and the other side of the main body (20), respectively. Furthermore, in the long axis direction, which is the previously set direction, the fixing rings (30) may be positioned with only a portion attached to the main body (20). As described in the first embodiment, a structure is implemented in which the fixing rings (30) are only partially attached to the main body (20) so that the fixing rings (30) can be easily attached to or removed from the main body (20). In addition, a structure is implemented in which the fixing rings (30) can be attached to or removed from the main body (20) in the short axis direction, so that the fixing rings (30) can be removed from any direction. In this way, the pusher (10) in the second embodiment can also be implemented in a structure in which the fixing rings (30) attached to the recess (20h) can be removed at once by inserting a finger into the second recess (22h) and lifting, just like in the first embodiment.

[0065] Additionally, a fixing groove (10h) is provided at one end of the handle rod (10), so that the fixing ring (30) can hinge rotate in the direction of the handle rod (10) and one end of the fixing ring (30) can be seated in the fixing groove of the handle rod (10).

[0066] In this way, a structure can be implemented in which a fixing ring (30) located on one side is coupled to the recessed groove (20h) and can also be fixed to the fixing groove (10h) of the handle rod (10), and a fixing ring (30) located on the other side is coupled to the recessed groove (20h) and can also be fixed to the fixing groove (10h) of the handle rod (10). Accordingly, a plurality of fixing rings (30) can serve as supports to stand the handle rod (10) upright.

[0067] Additionally, multiple fixing rings (30) can fix the cleaning cloth (70) on one side and the other side respectively, thereby firmly securing the cleaning cloth (70) and preventing it from coming off. Furthermore, through the multiple fixing rings (30), multiple cleaning cloths (70) can be provided, making it possible to attach them on one side and the other side of the main body (20). If one side of the cleaning cloth (70) becomes contaminated, only the cleaning cloth (70) attached to one side can be replaced and used.

[0068] Meanwhile, the plurality of fixing rings (30) can be rotated in the short-axis direction of the main body (20) depending on the implementation. That is, the plurality of fixing rings (30) are coupled to the recessed groove (20h) of the main body (20) located in front of the handle rod (10), and the fixing ring (30) and recessed groove (20h) located in the rear can be completely removed. Conversely, it is also possible to form a structure in which the fixing ring (30) and recessed groove (20h) located in the rear are completely coupled, and the fixing ring (30) and recessed groove (20h) located in the front are removed. Thus, the recessed groove (20h) located in the fixing ring (30) can be rotated in the short-axis direction.

[0070] FIG. 11 is a drawing of a pusher according to a third embodiment of the present invention, and FIG. 12 is a cross-sectional drawing of the part where the main body and the fixing ring of the pusher according to the third embodiment of the present invention are joined.

[0071] Referring to FIGS. 11 and 12, a plurality of fixing rings (30) according to the third embodiment of the present invention are formed with the same center, and a recessed groove (20h) can be provided in a form that can accommodate a plurality of fixing rings (30) at once.

[0072] Specifically, a plurality of fixing rings (30) have a narrow diameter and can be double-layered and joined in the recessed groove (20h). The plurality of fixing rings (30) can be positioned horizontally or spaced apart depending on the thickness of the cleaning cloth (70). Additionally, they can be positioned in a layered state on one side relative to the handle rod (10).

[0073] As shown in FIG. 12, a plurality of fixing rings (30) inserted into the recessed groove (20h) are positioned horizontally to firmly fix a cleaning cloth (70) with a thin thickness, and a cleaning cloth (70) with a thick thickness, such as a wet mop, can be formed to firmly hold the wet mop by fixing the fixing rings (30) up and down.

[0074] In this way, the fixing ring (30) according to the third embodiment is thinly provided in multiple pieces and inserted so as to overlap in the recessed groove (20h), thereby performing the function of firmly holding the cleaning cloth (70) regardless of the type of cleaning cloth (70).

[0076] FIG. 13 is a drawing of a pusher according to the fourth embodiment of the present invention, and FIG. 14 is a drawing showing a cross-section of a pusher according to the fourth embodiment of the present invention, which will be explained with reference thereto.

[0078] Referring to FIGS. 13 and 14, the fixing ring (30) according to the fourth embodiment of the present invention is composed of a plurality of rings, and can double-fix the cleaning cloth (70) on the outside and inside in the inner and outer directions of the main body (20).

[0079] As illustrated in FIGS. 13 and 14, the recessed groove (20h) of the main body (20) may be located on the outer and inner sides of the main body (20). Additionally, a fixing ring (30) coupled to the recessed groove (20h) of the main body (20) may also be provided at a position corresponding to the recessed groove (20h).

[0080] The size of the recessed groove (20h) of the main body (20) can be formed such that the inner circumference is smaller than the outer circumference, and the fixing ring (30) located on the inner side can be formed such that the circumference is smaller than the fixing ring (30) located on the outer side.

[0081] The fixing ring (30) can securely hold the cleaning cloth (70) from both the outer and inner sides. Additionally, depending on the implementation, although the fixing groove (10h) of the main body (20) and the fixing ring (30) have been described as being connected from the outer and inner sides in multiple numbers, it is also possible to provide more than multiple numbers.

[0083] FIG. 15 is an exploded view of a rolling pin according to the fifth embodiment of the present invention, and FIG. 16 is an exploded perspective view of a rolling pin according to the fifth embodiment of the present invention.

[0085] Referring to FIGS. 15 to 16, the push rod (1) according to the fifth embodiment of the present invention may further include a plate (40) mounted in the lower direction of the main body (20), an elastic material (50), and a pad (60).

[0086] The plate (40) of the pusher according to the fifth embodiment of the present invention may include a body plate (41) and a support plate (42).

[0087] The body plate (41) is inserted into the main body (20), is provided in a rectangular shape similar to the main body (20), and can be separated from the main body (20).

[0088] The support plate (42) is located in the lower direction of the body plate (41) and may include a projection (421) and a protrusion (422).

[0089] The protrusions (421) of the support plate (42) are provided in multiple numbers and function to fix the elastic material (50).

[0090] The protrusion (422) of the support plate (42) is located in the center and serves to shape the pad (60) so that it is convex in the center. As shown in FIG. 12, the protrusion (422) of the support plate (42) is formed in multiple numbers, but it is also possible to form it as a single large-area protrusion.

[0091] The elastic material (50) may be composed of an elastic material such as a sponge, rubber, or resin and may be fixed to the support plate. Additionally, the elastic material (50) may be fixed to the plate (40) as its surrounding portion is fastened to the protrusion (421) of the support plate (52).

[0092] The pad (60) can be formed from a fabric material such as a mop and can be formed in a convex shape at the center through the protrusion (422). In this way, the pad (60) has a convex shape at the center, so that cleaning can be done easily without the user having to apply strong force.

[0094] In addition to the embodiments described above, the present invention may include as additional embodiments a combination of at least one embodiment and known technology known to those skilled in the art, or a combination of at least two embodiments.
