Description

  The present invention relates to a handy mop that is held in one hand and wipes off dust at a site to be cleaned.

Conventionally, as this kind of handy mop, the one described in Patent Document 1 is known. This handy mop consists of a wiping cloth for wiping off dust and a mop body for mounting this wiping cloth. Inserting the bifurcated insertion plate at the tip of the mop body into the upper surface of the wiping cloth The wipe is attached to the mop body by being inserted into the gap, and cleaning is performed in that state.
If the wiping cloth becomes dirty and the cleaning function deteriorates, it will be replaced with a new wiping cloth. However, since the wiping cloth can only be used on one side, when wiping the heavily contaminated part, wipe it frequently in a short cycle. The cloth has to be replaced, which is inefficient.

  On the other hand, as an example of using both surfaces of a wiping cloth for cleaning, Patent Document 2 discloses that this sheet is formed by attaching a cylindrical wiping sheet to a flat sheet mounting member and rotating a handle attached to the sheet mounting member. A mop is disclosed in which the upper and lower surfaces of the wiping sheet are used for cleaning by inverting the mounting member upside down.

However, in the case of this mop, in order to be able to fix a handle such as a round bar bent into a crank shape at an arbitrary rotational position, for example, the connecting portion of the handle to the seat mounting member is tightened from the outside with a nut. A fixing mechanism for loosening or loosening is used, and the structure for fixing the handle is complicated.
JP 2003-265391 A JP-A-8-89465

  Therefore, an object of the present invention is to use both surfaces of the wiping cloth for cleaning, and to easily reverse the head when using both surfaces of the wiping cloth, and to lock the head in a required direction. An object of the present invention is to provide a handy mop that has a simple locking mechanism.

  In order to solve the above-described problem, according to the present invention, the wipe is mounted by inserting a head at the tip into a mounting hole inside the wipe, and a wipe having a dust wiping surface on both sides. A handy mop comprising a mop body configured as described above is provided. The mop body is formed by a grip handle and the head connected so that a connecting portion at a proximal end is rotatable about an axis in the front-rear direction to a mounting portion at the distal end of the handle. The connecting portion is provided with two locking bullets at positions opposite to each other across the axis, and a locking protrusion is formed on each locking bullet, and an attachment portion at the handle tip Are formed with two engaging holes for engaging the protrusions at opposite positions across the axis, and the head is moved up and down by the elastic engagement between the protrusions and the engaging holes. The handle can be locked at two inverted rotation positions.

  In the present invention, the front end surface of the attachment portion of the handle is formed in a horizontally long plane, the locking holes are formed in the left and right end portions of the front end surface, and the connecting portion of the head has a lateral width. From the left and right sides of the front end surface of the handle, the locking bullets that are thinner and narrower than the connecting portion extend so as to follow the front end surface. It is desirable to extend to the position of the locking hole at the end of the front end surface.

In the present invention, preferably, the head has two elongated right and left branch arms that branch into a fork and extend forward.
In this case, it is desirable that the resistance to pull out from the attachment hole of the wiping cloth is increased by corrugating the branch arm in the vertical direction.
Further, the branch arm may have a narrow plate shape whose plate surface faces in the vertical direction, and an edge frame that protrudes from the upper and lower surfaces may be formed on the periphery of each branch arm.
Alternatively, the branch arm may be formed to gradually narrow toward the distal end side, and the entire head may be formed to gradually narrow from the proximal end side toward the distal end side. .
Furthermore, protrusions for increasing resistance to pulling out from the attachment hole of the wiping cloth may be formed on the upper and lower surfaces of the branch arm.

According to the present invention, both sides of the wiping cloth can be used for cleaning only by rotating the head of the mop body and turning it upside down. In that case, the head may be simply rotated around the axis. Therefore, the reversing operation of the head is easy.
The head connecting portion is provided with two locking bullets at opposite positions across the rotation center axis for reversal, and two locking holes are formed in the mounting portion at the tip of the handle. When the head is turned upside down, the protrusions of the two locking bullets are elastically engaged with the two locking holes so that the head is locked at these two positions. The mechanism for locking is very simple, and locking at each position is performed reliably, and no operation of loosening or tightening the nut is required unlike conventional products.

  1 to 3 show a preferred embodiment of a handy mop according to the present invention. This handy mop has a wiping cloth 1 for wiping off dust and a mop body for attaching the wiping cloth 1 in a replaceable manner. It consists of two.

The wiping cloth 1 includes a rectangular cloth member 10 made of non-woven fabric folded in two at the longitudinal center position, and three cloth portions 10 a and 10 a that are vertically superposed are extended in the longitudinal direction of the wiping cloth 1. They are joined and integrated together by means such as sewing and welding along the bonding line 11, and the plan view has a substantially rectangular shape with rounded corners, and the upper and lower surfaces of the wipe 1 are for dust wiping. These are wiping surfaces 1a and 1b. Inside the wiping cloth 1, two attachment holes 12, 12 extending in the longitudinal direction of the wiping cloth 1 are defined and formed between the three bonding lines 11. These attachment holes 12 are opened at one end in the longitudinal direction of the wiping cloth 1, and the two branch arms 31, 31 formed in the head 21 of the mop body 2 are inserted into the attachment holes 12, 12 through the openings. Thus, the wipe 1 is attached to the mop body 2.
In addition, the said wiping cloth 1 can also be formed by superimposing two cloth members formed separately up and down, and couple | bonding these cloth members mutually.

  The cloth member 10 may be formed of a single non-woven fabric, but may also be formed by polymerizing a plurality of non-woven fabrics 10A and 10B as illustrated. Thus, when using several nonwoven fabrics, the softness | flexibility and volume feeling can be given to the wiping cloth 1 by using together the nonwoven fabric from which fiber density, a fiber entanglement form, or thickness differs. .

  As shown in FIGS. 4 to 6, the mop body 2 is formed by a synthetic resin grip 20 and a synthetic resin head 21 for mounting the wiping cloth 1. The handle 20 is formed in a shape in which the distal end side is bent slightly downward, and a laterally long and slightly flat mounting portion 22 is formed at the distal end, and the base portion of the head 21 is connected to the mounting portion 22. As shown in FIGS. 7 and 8, the portion 23 is connected by a pivot 24 so as to be rotatable around an axis L in the front-rear direction (longitudinal direction of the head). The pivot 24 extends from the central portion of the rear end surface of the connecting portion 23 along the axis L, and is rotatably inserted into a support hole 25 formed in the attachment portion 22 of the handle 20. Further, the end portion of the pivot 24 is divided into a plurality of locking portion pieces 24 a by axial slits 24 b, and these locking portion pieces 24 a are elastically locked to the hole edges of the support holes 25. Yes.

  In the figure, reference numeral 26 denotes a screw attached to the inside of the pivot shaft 24, and adjusts the rotational force of the head by adjusting the locking force of the locking piece 24a to the support hole 25, and at the same time, This is to prevent the pivot 24 from coming out of the support hole 25 by restricting the deformation of the stop piece 24a to the inside.

  The front end surface 22a of the attachment portion 22 of the handle 20 is a horizontally long plane, and the rear end surface of the connecting portion 23 of the head 21 is close to and faces the front end surface 22a. The lateral length (horizontal width) of the connecting portion 23 is shorter than the lateral length (horizontal width) of the mounting portion 22, and is thinner than the connecting portion 23 from the left and right sides of the connecting portion 23. Further, the two locking bullets 27, 27 each having a narrow flat plate shape extend in a direction opposite to each other along the front end surface 22a at positions close to the front end surface 22a, and the left and right ends of the front end surface 22a. It extends to the position near the part. Accordingly, the overall lateral width of the head 21 including the connecting portion 23 and the two locking bullets 27 and 27 is substantially equal to the lateral width of the front end surface 22 a of the mounting portion 22 in the handle 20.

  At the front end portions of the two locking bullets 27, 27, hemispherical locking protrusions 27a, 27a are formed so as to protrude toward the front end surface 22a side. Two locking holes 28, 28 are formed in the front end face 22a near the left and right ends, so that these protrusions 27a, 27a are elastically engaged. The two locking bullets 27 and 27 and the protrusions 27a and 27a and the two locking holes 28 and 28 are symmetrically disposed at positions opposite to each other with the axis L interposed therebetween. .

  Therefore, when the head 21 is rotated around the axis L so as to show an intermediate rotational state in FIG. 10, the two locking bullets are respectively provided at two rotational positions where the head 21 is turned upside down. The protrusions 27a and 27a of 27 and 27 are elastically engaged with the two locking holes 28 and 28, and the head 21 is locked to the handle 20 at these two rotational positions different in direction by 180 degrees. .

The head 21 includes a connecting portion 23, a base portion 30 extending from the connecting portion 23 and extending so as to have substantially the same width as the attachment portion 22 of the handle 20, and a bifurcated branch from the base portion 30. It has two elongated right and left branch arms 31 and 31 extending forward. These branch arms 31 and 31 have a narrow plate shape whose plate surface faces in the vertical direction, and the two heads 21 and 31 having these plate shapes and the base portion 30 make the entire head 21 complete. It has a plan view shape like a plate that is wide on the left and right and has a longitudinal groove 21a in the middle. Each of the branch arms 31, 31 is gradually narrower and thinner toward the tip side, and the tip portion 31 a is formed in a circular arc shape. It is formed so as to gradually become narrower from the base 30 side toward the distal end side. In addition, an edge frame 32 is formed on the periphery of each of the branch arms 31 and 31 and the base portion 30 so as to protrude in both the upper and lower surfaces along substantially the entire circumference.
By forming the head in such a shape, initial insertion when inserting the head into the mounting hole can be facilitated.

  Further, each branch arm 31 is corrugated in both the upper and lower directions, so that the insertion resistance of the wipe 1 to the attachment hole 12 is increased. This is the same as increasing the resistance (extraction resistance) against the escape from the mounting hole 12. As can be seen from FIG. 6, this corrugation is performed by forming corrugated irregularities composed of peaks 33 a and valleys 33 b on both upper and lower surfaces of the branch arm 31, but the waveform is smooth like a sine wave. Even an arc-shaped waveform may be a waveform obtained by rounding corners of a rectangular wave or a triangular wave.

  The height and pitch of the peaks 33a in the waveform may be appropriately set within a range in which the branch arm 31 can be inserted into the attachment hole 12 of the wiping cloth 1 and the pull-out resistance can be increased. Regarding the height of 33a, the apparent thickness increased by corrugation (between the tops of the upper and lower peaks at the position of the edge frame 32) with respect to the actual thickness (height of the edge frame 32) t of the branch arm 31. In general, the interval T) is set to be about 1.2 to 1.5 times. However, the optimum value of this numerical value may differ depending on the form and scale of the wipe 1 and the head 21.

  Thus, when the branch arm 31 is inserted into the mounting hole 12 of the wiping cloth 1 by corrugating the branch arm 31 in the vertical direction, the wave crest 33a portions are formed on the upper and lower hole surfaces of the mounting hole 12. Since it is pressed and locked to the hole surface by a frictional force, it is difficult to come off.

  Further, on the upper and lower surfaces of the two branch arms 31, 31, projections 34 are formed to further increase the resistance of the arm to the mounting hole 12 of the wiping cloth 1. The protrusion 34 is an arc-shaped protrusion that extends in the front-rear direction of the branch arm 31 so that the arc protrudes upward or downward at a position opposite to the upper and lower sides of the branch arm 31. When the branch arm 31 is inserted into the mounting hole 12, it is pressed against the upper and lower hole surfaces of the mounting hole 12.

  The handy mop having the above-described configuration is obtained by inserting the two branch arms 31 and 31 formed on the head 21 of the mop body 2 into the two attachment holes 12 and 12 formed inside the wiping cloth 1. As shown in FIG. 1, a wiping cloth 1 is attached to a mop body 2, and dust attached to a cleaning target such as a floor or furniture is wiped off by one wiping surface 1 a of the wiping cloth 1. At this time, in the mop body 2, the protrusions 27 a and 27 a of the two locking bullets 27 and 27 formed on the connecting portion 23 of the head 21 are two locking and formed on the attachment portion 22 at the tip of the handle 20. By elastically locking in the holes 28, the head 21 is held in a state where the head surface is directed in the vertical direction.

  Even if a force in the direction of dropping from the head 21 acts on the wiping cloth 1 due to wiping resistance or the like during cleaning, the corrugated branch arms 31 and 31 are strongly pressed against the upper and lower holes of the mounting holes 12 and 12 As a result, the resistance to pulling out from the mounting holes 12 and 12 is increased, so that the wiping cloth 1 does not fall off the head 21. The pull-out resistance at this time is further increased by forming the projections 34 on the two branch arms 31, 31 respectively.

When one wiping surface 1a of the wiping cloth 1 becomes dirty and the cleaning function is lowered, the wiping cloth 1 is turned upside down by rotating the head 21 around the axis L 180 degrees, and wiping on the opposite side of the wiping cloth 1 is performed. Clean using surface 1b. At this time, the two locking bullets 27 and 27 are also rotated by 180 around the axis L so that the positions of the two locking bullets 27 and 27 are switched to the left and right. By stopping, the head 21 is automatically fixed at a position where it is turned upside down.
Therefore, it is only necessary to rotate the head 21 around the axis L by 180 degrees, and it does not require any operation such as loosening or tightening the fixing nut unlike the conventional product. Inversion operation is easy.
