The outer surface 2f is formed with a curved surface curved in an arc shape from the top part 2h of the turning piece part 2 toward the pair of step parts 2g. With an axis core of a first shaft portion 2b as a base point 2i, the length r from the base point 2i to a position where a ridge part 3m abuts on the outer surface 2f becomes shorter from the top part 2h toward the step parts 2g. The base part 3a or the head part 1 is automatically moved from a state in which the ridge part 3m is positioned at the top part 2h with the longer length r to a state in which the ridge part is positioned at the step parts 2g with the shortest length r.SELECTED DRAWING: Figure 7

Description

[Technical Field]

[0001] The present invention relates to a cleaning tool having a head portion. [Background technology]

[0002] Patent Document 1 discloses a flooring wiper in which a handle is connected to a wiper head via a joint. The handle of this flooring wiper is connected to the wiper head so that it can be tilted at any angle.

[0003] When not in use, the floor wiper of Patent Document 1 is stored by placing the wiper head on the floor and leaning the handle against a wall, etc. In addition, commercially available floor wipers are sometimes stored in a hanging state by inserting a hook or the like placed on a wall, etc. through a through-hole at the rear end of the handle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-384 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the method of storing floor wipers in Patent Document 1, in which the wiper head is placed on the floor, uses up space unnecessarily, and if stored in a narrow space such as a hallway, the wiper head can become a nuisance as someone's foot may get caught on it.

[0006] Furthermore, with the hanging storage method for the floor wiper described above, the wiper head may become wobbly, and since the longitudinal direction of the wiper head and the longitudinal direction of the handle are perpendicular to each other, the wiper head takes up space in the storage area and becomes a nuisance.

[0007] SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a cleaning tool in which the head portion does not wobble during storage and which requires less space for storage. [Means for solving the problem]

[0008] In order to achieve the above object, the cleaning tool of the present invention is a cleaning tool comprising a flat head portion and a handle portion connected to the head portion via a pivoting piece portion, wherein the pivoting piece portion and the handle portion are rotatably connected by a first shaft portion or bearing portion provided at one end of the pivoting piece portion and a first bearing portion or shaft portion provided at the tip of the handle portion, wherein a bottomed gap portion extending toward the rear end is provided at the tip of the handle portion, and the gap portion houses an elastic body and a pressing piece connected to the elastic body, and a pair of step portions are provided on the upper outer surface of the pivoting piece portion, back to back, and approximately parallel to the shaft portion, and the tip of the pressing piece is provided with a protrusion portion that abuts against the starting point of the step portion. [Effects of the Invention]

[0009] Thus, with the cleaning tool of the present invention, the longitudinal direction of the head portion and the longitudinal direction of the handle portion are approximately parallel, and the main flat surface of the head portion and the handle portion are maintained facing each other, so the head portion does not wobble during storage, and the head portion does not occupy space in the storage location and become a nuisance.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described in detail below based on the illustrated embodiments. Fig. 1 is a perspective view of the entire cleaning tool, Fig. 2 is an exploded perspective view of the tip side of the cleaning tool, and Fig. 3 is a perspective view of the tip side of the cleaning tool in an assembled state. The cleaning tool is composed of a flat head part 1 and a handle part 3 connected to this head part 1 via a pivot piece part 2.

[0012] The cleaning tool is manufactured using a hard synthetic resin material, but it can also be manufactured using metals such as aluminum in appropriate parts instead of synthetic resin material.

[0013] The head 1 has a notch 1b of a predetermined width extending inward from one long side surface 1a to just past the center of the head 1. The surface of the head 1 is made of a rough resin material to make it easy to attach a cleaning sheet made of nonwoven fabric or the like, and the cleaning sheet can be attached so that it covers the main flat surface 1c. However, it can also be used without attaching a cleaning sheet.

[0014] The rotating piece 2 has a first shaft portion 2b provided at the upper end 2a and a second shaft portion 2d provided at the lower end 2c, and this second shaft portion 2d has an axial direction perpendicular to the axial direction of the first shaft portion 2b.

[0015] A rod-shaped shaft body 2e can be inserted into the first shaft portion 2b, and by inserting the shaft body 2e into the bearing portion described later at the tip of the first shaft portion 2b and the handle portion 3, the rotating piece portion 2 and the handle portion 3 are connected so as to be able to rotate freely.

[0016] Similarly, by engaging the second shaft portion 2d with a bearing portion (not shown) provided on the innermost side of the notch portion 1b of the head portion 1, the rotating piece portion 2 and the head portion 1 are connected to each other so as to be freely rotatable.

[0017] The rod-shaped handle portion 3 is composed of a base portion 3a that connects to the pivot piece portion 2 and a main body portion 3b that connects to this base portion 3a, and the base portion 3a and the main body portion 3b can be separated by releasing the engagement portion 3c.

[0018] This engagement part 3c maintains an engaged state by fitting a push button provided at the tip of the main body part 3b into a through hole provided in the base part 3a. This push button always has a repulsive force against the outside, so once the above-mentioned engaged state is achieved, the base part 3a and the main body part 3b will not separate unless the push button is pressed with a finger.

[0019] A handle 3e that can be held by hand and a through-hole 3f provided at the outermost rear end of the handle 3e are provided at the rear end of the main body 3b of the handle 3. The base 3a of the handle 3 has a cylindrical insertion hole 3d at one end and a pair of clamping pieces 3g at the other end that clamp the upper end 2a of the rotating piece 2.

[0020] These clamping pieces 3g are provided with bearing portions 3h which are through holes into which the shaft body 2e can be inserted, and a gap portion 3i is provided which extends from the base of the clamping piece 3g toward the rear end on the insertion hole 3d side.

[0021] The cavity 3i has a bottom, and a bottom surface 3j is provided at the back. The cylindrical cavity 3i can accommodate an elastic body 3k, such as a coil spring, and a pressing piece 3l connected to the elastic body 3k.

[0022] When assembling the cleaning tool, first, the elastic body 3k is accommodated at the rear side of the gap 3i and the pressing piece 3l at the front side, and then the first shaft portion 2b and the bearing portion 3h are connected by the shaft body 2e, and the base portion 3a of the handle portion 3 and the rotating piece portion 2 are integrated so as to be freely rotatable around the shaft body 2e.

[0023] In addition, fixing pieces are provided on the surface of the bottom portion 3j and the back surface of the pressing piece 3l to be inserted into the ends of the coil spring, which is the elastic body 3k, and these fixing pieces fix the coil spring so that it can expand and contract without slipping.

[0024] The pressing piece 3l housed in the cavity 3i is constantly subjected to a repulsive force by the elastic body 3k, and the protruding portion 3m at the tip of the pressing piece 3l is constantly in contact with the rotating piece 2. The side of the tip of this pressing piece 3l is V-shaped, and the protruding portion 3m, which is the base point of the included angle of this V, forms a straight line parallel to the shaft body 2e.

[0025] Next, similar to the rotatable connection work using the first shaft portion 2b and the bearing portion 3h, the second shaft portion 2d of the rotating piece portion 2 is connected to a bearing portion (not shown) located at the back of the notch portion 1b of the head portion 1, thereby rotatably integrating the rotating piece portion 2 and the head portion 1.

[0026] In this way, the tip side cleaning tool shown in Figure 3 can be assembled, and finally, by inserting the main body part 3b into the insertion hole 3d of the handle part 3, it becomes as shown in Figure 1, and assembly of the cleaning tool is completed.

[0027] Figure 4 is a perspective view of the cleaning tool in a state where the base 3a of the handle 3 is raised perpendicular to the main flat surface 1c of the head 1, Figure 5 is a perspective view of the state where the base 3a of the handle 3 is lifted upward so that it is parallel to the main flat surface 1c of the head 1, and Figure 6 is a perspective view of the state where the base 3a is tilted to one side around the shaft 2e from the state shown in Figure 5.

[0028] The base 3a shown in Fig. 6 cannot be tilted any further because it abuts against the corner 1d of the notch 1b of the head 1. When cleaning a narrow space with the main flat surface 1c of the head 1 shown in Fig. 5 standing upright, the handle 3, which will be described later, does not automatically move until it is parallel to the longitudinal direction of the head 1, so cleaning is not hindered even when the head 1 is inserted deep into a narrow space.

[0029] 7 and 8 are explanatory diagrams illustrating the rotation of the handle 3 relative to the rotating piece 2 from the state in Fig. 4 to the state in Fig. 3. The outer surface 2f of the upper end 2a of the rotating piece 2 is provided with a pair of steps 2g that are back-to-back and substantially parallel to the shaft 2e.

[0030] Furthermore, the outer surface 2f is formed with a curved surface that curves in an arc from the top 2h of the rotating piece 2 toward the pair of step portions 2g. The protruding portion 3m of the pressing piece 3l, which is pressed from behind by the elastic body 3k, is constantly in contact with this curved outer surface 2f.

[0031] In the illustrated side view in which the protrusions 3m are in contact with the outer surface 2f, the center of the shaft 2e, i.e., the axial center of the first shaft portion 2b, is taken as the base point 2i, and the length r from this base point 2i to the point where the protrusions 3m are in contact with the outer surface 2f becomes shorter from the apex 2h toward the step portion 2g. In other words, the length r1 from the base point 2i to the protrusions 3m shown in Figure 7 is longer than the length r2 shown in Figure 8.

[0032] The spring, which is the elastic body 3k housed in the cavity 3i of the base 3a, is compressed and has a strong elastic force, as shown in the side view diagrams of Figures 7 and 8, and is trying to change from a state in which the length r is long to a state in which the elastic body 3k, which is a coil spring, is stretched and has a weaker elastic force, and is trying to change from a state in which the length r is short.

[0033] In other words, the base 3a automatically moves from a state in which the longest protrusion 3m, with its length r, is located at the top 2h to a state in which the base 3a is located at the stepped portion 2g, with its length r being the shortest. Note that when the handle 3 is fixed, this movement is achieved by automatically rotating the head 1.

[0034] In addition, at the starting point where the step of the step portion 2g occurs, a groove portion that is further recessed inward is provided, and when the base portion 3a automatically rotates from the state shown in Figure 7 to the state shown in Figure 8, the protrusion portion 3m fits into this groove portion, thereby maintaining the state shown in Figure 9.

[0035] Furthermore, a recessed groove 2j recessed inward is also provided at the top 2h of the outer surface 2f, and the protrusion 3m fits into this recessed groove 2j to maintain the state shown in Figures 4 and 5. However, it is not necessary to provide a recessed groove into which the protrusion 3m fits.

[0036] Then, the engaged state is released by applying a force in the direction of rotation against the resistance that occurs when rotating the handle portion 3 from the state shown in FIGS.

[0037] Figure 9 is a perspective view of the cleaning tool and storage case C with the protrusion 3m abutting against the step 2g and the protrusion 3m fitted into the groove of the step 2g, and Figure 10 is a perspective view of the cleaning tool stored in the storage case C.

[0038] When cleaning, with head 1 in contact with the floor surface, force is applied to handle 3 via grip 3e, and cleaning is performed against the automatic rotation force described above. After cleaning, when head 1 is lifted from the floor by lifting handle 3, the automatic rotation force acts on head 1, changing the state of the cleaning tool to that shown in Figure 9.

[0039] Furthermore, since the step portions 2g are arranged back to back on both sides of the rotating piece portion 2, when cleaning is finished, the head portion 1 can be rotated in any direction left or right by lifting the grip portion 3e while tilting the handle portion 3 slightly in any direction left or right relative to the head portion 1.

[0040] Then, with the main flat surface 1c of the head 1 and the handle 3 facing each other and approximately parallel as shown in Fig. 9, the head 1 can be inserted into the opening C1 of the storage case C in the direction of the arrow shown, thereby enabling storage in the state shown in Fig. 10. Alternatively, in the state of the cleaning tool shown in Fig. 9, a hanging rod or the like placed on a wall or the like can be inserted into the through-hole 3f and the cleaning tool can be stored in a hanging state.

[0041] Since the cleaning tool is maintained in the state shown in FIG. 9, the head portion 1 does not wobble relative to the handle portion 3, and the head portion 1 can be easily inserted into the opening C1.

[0042] Thus, with the cleaning tool of the present invention, the longitudinal direction of the head portion 1 and the longitudinal direction of the handle portion 3 are approximately parallel, and the main flat surface portion 1c of the head portion 1 and the handle portion 3 are maintained facing each other, so the head portion 1 does not wobble during storage, and the head portion 1 does not occupy space in the storage location and become a nuisance.
