[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wiper used for cleaning a flooring, and more particularly, to a flooring wiper having both a mop function and a broom function.
[0002]
[Prior art]
Conventionally, various types of wipers having a sponge head attached to a head holder connected to the tip of a handlebar and a wiping cloth wrapped around the sponge head have been known. As one example, Patent Document 1 discloses a wiper having both a mop function and a broom function. This wiper uses a horizontally long triangular prism-shaped sponge head having an inverted triangular cross-sectional shape attached to the tip of a handle bar, and is attached to the sponge head with a wiping cloth. It has the convenience of sweeping and cleaning like a broom using the deflection of the head.
[0003]
Considering that this type of wiper bends like a broom for sweeping cleaning, it is easier to use a sponge head that is as flexible as possible. However, when the flexibility of the sponge head is increased in accordance with the sweeping cleaning, the sponge head is too soft and difficult to use when performing the wiping cleaning as a mop. Therefore, in general, the sponge head is provided with an intermediate flexibility such that both the sweeping cleaning and the wiping cleaning can be performed, but in this case, it is slightly too hard to perform the sweeping cleaning, This can be half-hearted, such as being too soft to wipe clean. For this reason, if the sponge head can be flexibly bent when performing a sweeping cleaning like a broom, but if the sponge head can be configured to have a necessary rigidity when performing a wiping cleaning as a mop, a wiper can be used. The usability will be significantly improved.
[0004]
Further, when connecting the sponge head with the head holder at the tip of the handlebar, conventionally, a narrow connecting convex wall is formed on the top surface of the sponge head, and this convex wall is connected with the head holder. However, the more flexible the sponge head, the lower the rigidity of the protruding wall, so that when a force from the handle bar acts during cleaning, the sponge head is easily bent sharply at the position of this convex wall, There is also a problem that it is difficult to transmit sufficient power.

[Problems to be solved by the invention]
The technical problem of the present invention is to provide a flooring wiper having a function of a mop and a function of a broom by attaching a horizontally long triangular prism-shaped sponge head having an inverted triangular cross section to the tip of a handle bar. When performing a sweeping cleaning like a broom, it flexes flexibly, but when performing a wiping cleaning as a mop, it has the necessary rigidity and the connection strength between the handlebar and the sponge head. And to improve the usability as a wiper.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, a flooring wiper of the present invention includes a handlebar for operation, a head holder that is tiltably attached to a tip of the handlebar via a connecting portion, and a floor sticker that is attached to the head holder. A sponge head having a horizontally long triangular prism shape and a wiping cloth detachably attached to the sponge head. The sponge head has an inverted triangular cross-sectional shape, and a top surface thereof has a longitudinal direction of the sponge head. And a holder mounting portion formed between these grooves, and a central position of the holder mounting portion parallel to the groove and deeper than the groove at a central position of the holder mounting portion. The head holder has a plate-shaped main part joined to the upper surface of the holder mounting part of the sponge head, and a downward direction from both ends in the width direction of the main part. Extend the above two recesses Each has a vertical wall, and a reinforcing plate extending downward from the center of the lower surface of the main body and fitted in the plate insertion groove, and the reinforcing plate also serves as fixing means, The head holding body is fixed to the sponge head by bonding and fixing both surfaces of the reinforcing plate to the sponge head in the plate insertion groove.
[0008]
In the flooring wiper having the above configuration, when performing wiping cleaning as a mop, one of the two slopes of the sponge head having an inverted triangular cross section is pressed against the floor surface and slid back and forth or left and right, and a broom is used. When such a sweeping cleaning is performed, the sponge head is vertically oriented, and the lower end is pressed against the floor surface and moved left and right, so that the lower half of the sponge head is bent like a broom to remove dust. Try to sweep.
[0009]
At this time, even if the sponge head is flexible, the reinforcing plate inserted into the plate insertion groove imparts an appropriate rigidity to the upper half of the sponge head. The sponge head does not unnecessarily bend or bend due to the reinforcing plate being reinforced by the reinforcing plate during wiping cleaning. be able to.
[0010]
In particular, the holding member mounting portion to which the force from the handle bar is directly applied is reinforced by the reinforcing plate so as not to bend easily, and at the same time, the reinforcing plate is adhered and fixed in the plate insertion groove, thereby strengthening the reinforcing member. Since the plate and the portions of the sponge head located on both sides of the reinforcing plate are not relatively displaced, the force from the handle bar acts on the sponge head through the head holder during cleaning, and Even if the heads on both sides receive a force in the direction of extension or compression, they do not move relative to one another with the reinforcing plate, so that the force from the handle bar is sufficiently transmitted to the sponge head. Become superior in operability. Moreover, the holding member mounting portion of the sponge head is sandwiched from both sides by the two vertical walls of the head holding member, and is held in a direction in which the plate insertion groove is closed. Therefore, the reinforcing plate is held in the plate insertion groove. As a result, the adhesive strength is increased, and even if a force in the pulling direction acts, the adhesive does not easily come off. Therefore, the connection strength between the head holder and the sponge head becomes very large.
[0011]
In the present invention, the lateral width of the holder attaching portion in the sponge head is formed larger than the depth of the concave groove, and the upper surface of the holder attaching portion is formed on both sides of the holder attaching portion through the concave groove. Is desirably formed to be lower than the upper surface of the end wall portion located at a height of about 1/3, and the depth of the plate insertion groove is preferably 1/3 to 2/3 of the height of the sponge head.
[0012]
According to another configuration aspect of the present invention, the connecting portion includes a pair of bearing portions formed on the upper surface of the main body portion of the head holder, and is attached to these bearing portions and extends in the width direction of the head holder. A support shaft, and a connection pipe connected to the support shaft so as to be tiltable in a longitudinal direction of the sponge head by fitting the support shaft into a connection hole at a tip end, and the connection pipe is provided with the handle. The connecting hole at the distal end of the connecting pipe is formed such that the diameter of the hole is the smallest at the center in the axial direction, and the diameter gradually increases toward both ends of the hole. This allows the handle bar to tilt in the width direction of the sponge head.
[0013]
In the present invention, preferably, when the handlebar is rotated in the longitudinal direction of the sponge head and tilted to a position where the handlebar comes into contact with the main body, on the side surface of the handlebar and the upper surface of the main body of the head holder. Is to have a stopper that engages with
With such a configuration, when the flooring wiper is not used, it is hung on the hook of the storage location or stowed on the wall and stored, with the sponge head oriented parallel to the handlebar, By engaging the stoppers provided on the handle bar and the head holder with each other, the sponge head is prevented from protruding greatly from side to side, and the wiper is made compact and stable in a state where bulkiness is eliminated. Can be stored and stored.
[0014]
In the present invention, the stopper comprises a projection and a dent that engage with each other, one of the projections or the dent is formed on both left and right side surfaces of the connection pipe, and the other is a main body of the head holder. It is formed on the upper surface.
Further, in the present invention, the wiping cloth is attached so as to cover both side surfaces from the lower end of the sponge head, and both ends of the wiping cloth exceed the concave groove and are attached to the main body and the holder. It is sandwiched so as to reach the space between the grooves, and is fixed in a state of being sharply bent at the position of the concave groove and the vertical wall.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 and 2 show a preferred embodiment of the present invention. This flooring wiper is tiltably attached to a handlebar 1 for operation via a connecting portion 2 at a tip end of the handlebar 1. The head holder 3 includes a horizontally long triangular prism-shaped sponge head 4 attached to the head holder 3, and a wiping cloth 5 detachable from the sponge head 4.
[0016]
The sponge head 4 is formed of a synthetic resin foam having both flexibility enough to cause bending like a broom and rigidity enough to press the wiping cloth 5 against a portion to be cleaned with a necessary force. Its cross-sectional shape is an inverted triangular shape with one apex angle pointing downward, and a shape like an isosceles triangle with two V-shaped sides on both sides of this apex angle almost equal. You are. The category of the isosceles triangle includes an equilateral triangle. Also, each apex of the triangle is rounded. Therefore, the sponge head 4 is configured such that its width and rigidity increase as it goes upward, and its flexibility increases as it goes downward. When performing wiping cleaning as a mop, the sponge head 4 has a V-shape. In the case of selectively using the two inclined side surfaces 4A and 4B to perform sweeping cleaning like a broom, the flexible lower end portion 4C is bent to sweep dust.
[0017]
On the top surface of the sponge head 4, two shallow concave grooves 4a, 4a parallel to each other are formed over the entire length in the longitudinal direction, and a holder attaching portion 4b is defined between these concave grooves 4a, 4a. Further, end walls 4c, 4c are formed on both sides in the width direction of the holder attaching portion 4b via the concave grooves 4a, 4a.
[0018]
The width of the holder attaching portion 4b is larger than the depth of the concave grooves 4a, 4a, and the upper surface of the holder attaching portion 4b is a plane slightly lower than the upper surfaces of the end wall portions 4c, 4c. These steps are substantially the same as the thickness of the main body 3a of the head holder 3 described later. At the center of the upper surface of the holder attaching portion 4b, a plate insertion groove 4d parallel to the concave grooves 4a, 4a is formed over the entire length of the sponge head 4. The depth of the plate insertion groove 4d is deeper than the depth of the concave grooves 4a, 4a, and the preferable depth is in the range of 1/3 to 2/3 of the height H of the sponge head 4.
[0019]
The head holder 3 has a plate-shaped main part 3a joined to the upper surface of the holder mounting part 4b of the sponge head 4, and the two concave grooves extending downward from both ends in the width direction of the main part 3a. Two vertical walls 3b, 3b respectively fitted to 4a, 4a, and one flexible reinforcing plate 3c extending downward from the center of the lower surface of the main part 3a and fitting into the plate insertion groove 4d. The main body 3a, the vertical walls 3b, 3b, and the reinforcing plate 3c are integrally formed of a hard or semi-hard material such as a synthetic resin. The overall length is the same as or slightly shorter than the sponge head 4.
[0020]
The main body portion 3a is formed to have substantially the same width as the holder attaching portion 4b of the sponge head 4, and the main body portion 3a is mounted on the holder attaching portion 4b and the vertical walls 3b, 3b on both sides thereof are attached. Even if the holder mounting portion 4b is fitted into the concave grooves 4a, 4a, the holding wall mounting portion 4b is hardly compressed by the vertical walls 3b, 3b.
[0021]
The vertical walls 3b, 3b have a width and a height that fit in the grooves 4a, 4a, and the end 5a of the wiping cloth 5 wound around the sponge head 4 is placed in the grooves 4a, 4a. The sponge head 4 is elastically sandwiched between the sponge head 4 and the sponge head 4.
[0022]
Further, the reinforcing plate 3c is inserted into the plate insertion groove 4d of the sponge head 4 to increase the rigidity of the upper half of the sponge head 4, and the upper half is compressed or deformed more than necessary during cleaning. It is formed to be thinner than the main body 3a and the vertical walls 3b, 3b, so that appropriate rigidity and elasticity are imparted. By inserting the reinforcing plate 3c into the plate insertion groove 4d and bonding and fixing the reinforcing plate 3c into the plate insertion groove 4d with an adhesive or a double-sided tape applied to both left and right surfaces of the reinforcing plate 3c, the head holder 3 is formed. It is attached to the sponge head 4. Therefore, the reinforcing plate 3c also serves as a fixing means for fixing the head holder 3 to the sponge head 4.
[0023]
In this case, the holder attaching portion 4b of the sponge head 4 is sandwiched from both sides by the vertical walls 3b, 3b of the head holder 3, and is held in the direction in which the plate insertion groove 4d is closed. It is sandwiched in the plate insertion groove 4d and firmly adheres to the sponge head 4, and does not easily come out even if a force in the pulling direction acts. Although the main body 3a of the head holder 3 is not directly bonded to the sponge head 4, the main body 3a is within a range that does not hinder the end of the wiping cloth 5 between the sponge head 4 and the sponge head 4. It may be partially adhered.
[0024]
In the case of the reinforcing plate 3c shown in FIG. 2, the reinforcing plate 3c has a plate shape with a uniform thickness. It can also be formed to increase the flexibility as it approaches the tip. In this case, it is desirable that the thickness be reduced toward the tip.
[0025]
The connecting part 2 includes a pair of bearings 6, 6 formed on the upper surface of the main body 3 a of the head holder 3, and a support attached to these bearings 6, 6 and extending in the width direction of the head holder 3. It has a shaft 7 and a connecting pipe 9 that is tiltably connected to the supporting shaft 7, and this connecting pipe 9 constitutes a tip portion of the handle rod 1.
[0026]
The connection pipe 9 is connected to the support shaft 7 by fitting the support shaft 7 into a connection hole 8 at the tip of the connection pipe 9. The connection hole 8 is, as shown in FIG. The hole diameter is the smallest at the center position in the axial direction, and is formed so that the hole diameter gradually increases toward both ends of the hole. In other words, the sponge head 4 can be tilted to both sides in the width direction by a predetermined angle. In order to easily tilt the handle bar 1 in such a direction, as can be seen from FIG. 3, the portions of the bearing portions 6, 6 above the mounting position of the support shaft 7 are gradually advanced. The connecting pipe 9 is formed so as to expand, and the width of the distal end portion of the connecting pipe 9 is gradually narrowed. Thus, when the wiper is used like a broom while gripping the handlebar 1, the sponge head 4 is rotated by a predetermined angle in the width direction to reduce the resistance between the sponge head 4 and the cleaning target portion, and the actual broom is used. As a result, the wiper 5 can be prevented from being displaced from the sponge head 4 as much as the resistance to the cleaning target portion is reduced. The handle bar 1 can be freely rotated about the support shaft 7 also in the longitudinal direction of the sponge head 4.
[0027]
Further, the handle bar 1 is pivoted in the longitudinal direction of the sponge head 4 on both the left and right side surfaces of the handle bar 1 and the upper surface of the main body 3a of the head holder 3 to a position where it comes into contact with the main body portion 3a. Stoppers 12 are provided which engage each other when tilted. The stopper 12 comprises a projection 10 and a depression 11 which engage with each other. In this embodiment, the projection 10 is formed on the left and right side surfaces of the connecting pipe 9 at the tip of the handlebar 1. And recesses 11 are formed at two locations on the left and right sides of the connecting portion 2 on the upper surface of the main portion 3a. However, the projections 10 may be formed on the upper surface of the main body 3a, and the depressions 11 may be formed on both side surfaces of the handle bar 1. In the illustrated embodiment, the depression 11 is formed between the pair of projecting walls 11a.
[0028]
As the wiping cloth 5, for example, a nonwoven fabric containing at least a part of ultrafine fibers of 1 to 9 μm, a nonwoven fabric impregnated with a dusting agent, water, or the like, a wiper paper, or the like is suitably used. Such a wiping cloth 5 is attached to the sponge head 4 so as to wrap the upper surfaces of the side surfaces 4A, 4B and the end walls 4c, 4c from the lower end thereof, and the both ends 5a, 5a of the wiping cloth 5 are attached. The sponge head 4 is fixed by being elastically sandwiched between the vertical walls 3b, 3b of the head holder 3 and the sponge head 4 in the concave grooves 4a, 4a. In this case, as shown in FIG. 2, the end 5a of the wiping cloth 5 is sandwiched so as to reach the space between the main body 3 and the holder attaching portion 4b beyond the groove 4a, and the groove 5a and the vertical wall 3b The fixing strength can be increased by fixing the device in a sharply bent state at the position.
[0029]
In the flooring wiper having the above-described configuration, when performing wiping cleaning as a mop with the wiper, one of the two inclined side surfaces 4A and 4B of the sponge head 4 having an inverted triangular cross section is pressed against the floor surface to move back and forth or left and right. When performing a sweeping cleaning like a broom, the sponge head 4 is turned vertically, and the lower end portion 4C is pressed against the floor surface and moved left and right, so that the lower end portion 4C is moved to the broom. To sweep relatively large dust while bending.
[0030]
At this time, even if the sponge head 4 is relatively flexible, a moderate rigidity is imparted to the upper half of the sponge head 4 by the reinforcing plate 3c inserted into the plate insertion groove 4d. When used as a mop, wiping and cleaning can be performed by strongly pressing at least the upper half of the side surfaces 4A and 4B against the floor surface, and when used as a broom, the sponge head 4 The lower end portion 4C not reinforced by the reinforcing plate 3c flexes flexibly, and the handle bar 1 tilts in the width direction of the sponge head 4 to support the flexure of the sponge head 4, so that a feeling of use like a broom is used. Can be used for sweeping cleaning.
[0031]
In particular, since the reinforcing plate 3c is bonded and fixed in the plate insertion groove 4d, the relative position between the reinforcing plate 3c and the portions 4e, 4e of the sponge head 4 located on both sides of the reinforcing plate 3c. Therefore, for example, at the time of sweeping cleaning, the tip portion 4C of the sponge head 4 bends left and right, so that a force in the extension direction acts on the portion 4e on one side of the reinforcing plate 3c. Even if a force in the compression direction acts on the side part 4e, the parts 4e, 4e and the reinforcing plate 3c do not relatively shift and move, so that the acting force from the handle rod 1 acts on the sponge head 4. It will be transmitted reliably and sufficiently.
[0032]
When the flooring wiper is not used, it is hung on the hook of the storage place or leaned against the wall and stored. At this time, the sponge head 4 is oriented in parallel with the handlebar 1 as shown in FIG. By engaging the stoppers 12 provided on the handle bar 1 and the head holder 3 with each other, it is possible to prevent the sponge head 4 from protruding largely right and left and to reduce the bulk of the wiper, thereby reducing the size of the wiper. And can be stably stored and stored.
[0033]
【The invention's effect】
As described in detail above, according to the flooring wiper of the present invention, the reinforcing plate of the head holder is inserted into the plate insertion groove of the sponge head to provide the sponge head with appropriate rigidity and flexibility. Thus, the sponge head can be configured to flex flexibly when performing sweeping cleaning like a broom, but to have necessary rigidity when performing wiping cleaning as a mop. Further, the reinforcing plate is also used as fixing means for fixing the head holder and the sponge head, and the reinforcing plate is adhered and fixed in the plate insertion groove, so that the connection strength between the head holder and the sponge head is reduced. As a result, the sponge head can be prevented from being unnecessarily deformed during cleaning, and the usability as a wiper can be improved.
