Description

The present invention relates to a cleaning tool for cleaning a floor surface or a wall surface, and more particularly to a cleaning tool having a replaceable cleaning head and wiping body, and a handle.

Conventionally, broom-shaped long handle type handle and handy type have been widely used as cleaning tools for homes and workplaces. These cleaning tools generally include a wiping member that directly contacts the floor surface, a cleaning head for mounting the wiping member, and a handle for mounting the head. In particular, a cleaning tool of the type in which the head can be easily removed from the handle or the wiping member from the head and replaced can be often used.

FIG. 13 shows a cleaning tool for a floor having a T-shaped rotating head, which is disclosed in JP-A-2005-097793 (Patent Document 1).
The head 121 connected to the long handle 102 includes a rotary bearing 109, a rotary shaft hole 119, a lock button 118, a pair of left and right rotary shaft bodies 110 and 111, and a hollow body externally fitted to the rotary shaft bodies. It has 112 and 113. The wiping body 101 having the bag portion 123 is held by the head 121. In the holding state, the pair of left and right rotating shafts horizontally spreads in the bag portion, and the head has a T-shape to hold the wiping body. When the lock button 118 is pressed, the head is released, the pair of left and right rotary shafts hang down by gravity, and the wiping body separates and falls from the head.

The cleaning tool is characterized in that the wiping body can be detachably attached to the head with one touch. However, the attachment/detachment mechanism cannot be manufactured inexpensively, and it is difficult to reduce the weight because the hard head having the attachment/detachment mechanism has a large weight, and it is not a cleaning tool that can be used by seniors at home without burden.
Furthermore, in order to maintain the strength to support a heavy and hard head, the weight of the entire cleaning tool is large, and if you drop the cleaning tool on the floor or collide it with the wall surface, your hand may be impacted. , There is a risk of damaging the floor and walls.

Further, a conventional floor type cleaning tool including the cleaning tool generally has a detachable mechanism in which the head is fixed to the handle by inserting the upper end of the head into the handle and the head and the handle can be separated by pressing a button on the head. Therefore, in the rental application, it is possible to deliver to the customer a head and a wiping body having various shapes and a common handle that meet the customer's request. However, since the weight of the hard head is large and bulky as described above, it is inconvenient for delivery, and it is also necessary to take damage prevention measures such as packing with a cushion material in order to avoid damage to the head during delivery. Further, the attachment/detachment mechanism also requires a certain level of strength, which increases the weight of the cleaning tool as a whole and increases the manufacturing cost.

FIG. 14 is a handy device provided with a wiping body separating mechanism, which is disclosed in Japanese Unexamined Patent Application Publication No. 2010-154886 (Patent Document 2), which can easily detach the wiping body without touching a dirty wiping body. 3 shows a type of cleaning tool.
The wiping body separation mechanism is a cleaning tool formed by inserting the insertion body 220 into the bag-shaped portion from the insertion opening 214 of the wiping body 210 and engaging the insertion body locking fastener 224 and the wiping body locking fastener 216. In 201, a separation part 230 is arranged between the insert body locking fastener 224 and the grip part 240, and the separation part 230 is composed of a separation ring body 231 and a cutting body integrally connected to the separation ring body 231, and moves the separation ring body 231. Then, the cutting body cuts the engagement between the locking fasteners to separate the wiping body 210 from the cleaning tool grip 250 without touching the wiping body 210.

The cleaning tool achieves the purpose of easily detaching the wiping body without touching the soiled wiping body. However, it is difficult to manufacture at low cost because of the large number of parts. In addition, since the head (insert 220) is integrated with the handle (grip 240) due to the structure of the separating portion, various shapes of head and wiping body can be selected according to the user's request. It has drawbacks that cannot be used.

FIG. 15 shows a cleaning tool disclosed in Japanese Unexamined Patent Publication No. 10-290769 (Patent Document 3), in which the work shape of the mop head can be changed to a handy type or floor by expanding and contracting the mop head. ..
(15A) is a plan view of the mop head 304F in a shortened state, and its sectional view is (15B). The mop head 304F is formed in a hollow shape by an elastic material having elasticity and airtightness such as rubber or synthetic resin, and a handle 305 is attached thereabove via a hard substrate 330. Air is supplied and discharged through the through hole 332 by the attached pump means 331.

The mop head can be used as a handy type or a small floor mop in a natural state in which air is not pressed. At that time, the sheet-shaped or bag-shaped wiping cloth made of non-woven fabric is locked to the upper surface of the substrate 330 by the fastening means 333.

The mop head expands in the longitudinal direction when air is pressed in, and can be used as a large floor mop. (15C) is a plan view of the mop head 304F in an extended state, and its sectional view is (15D). The sheet-shaped wipe cloth made of non-woven fabric is locked to the upper surface of the substrate 330 by the fastening means 333.

Since the mop head is made of an elastic material having airtightness and elasticity, the mop head expands as the air is pressed in, as long as the elastic limit is not exceeded. Since the shape of the mop head is changed by adjusting the amount of press-fitted air or the pressure of the internal air, the aim is to make one cleaning tool serve as both a handy type cleaning tool and a floor cleaning tool.

However, since it is not easy to adjust the amount of press-fitting air so that the mop head extends to a specific shape, it is regulated so that the extending direction of the mop head is only the longitudinal direction with a hard reinforcing plate or the like. It is necessary to provide the fastening means 333 for the wiping cloth on the hard substrate 330, and to fasten the wiping cloth by winding it from the lower surface to the upper surface of the mop head. Therefore, the entire surface of the mop head cannot be covered with a wipe, the exposed protrusions may damage the floor, and it is difficult to meet the demand for weight reduction.

An air bag type cleaning tool capable of injecting air into the bag body.

According to the first aspect of the present invention, the cleaning tool has a wiping body and a head, the head on which the wiping body is mounted is made of an air bag (bag body), and the head is in a substantially tense state by injecting air. The wiping body retains a cleanable shape by inflating until it reaches a certain level. Since the head is super lightweight, it can be cleaned even by seniors without a feeling of burden, and since the air inside the bag acts as a cushion, it has a shock absorbing performance and a cleaning tool having a soft touch feeling can be provided.

The bag body that is inflated by injecting air is inflated in the bag-shaped inclusion space inside the base cloth that forms the wiping body. Since the base cloth is made of a material that does not have elasticity, the shape of the base cloth when the inclusion space expands to the maximum extent is fixed, and the base cloth does not expand further. This shape is the maximum expansion shape of the base cloth. Even if the shape of the base cloth does not reach the maximum expansion shape, the base cloth is in the cleanable shape as long as the wiping body maintains the cleanable shape. Here, when the bag body is made of a stretchable material such as a rubber balloon, when air is injected into the bag body, the bag body expands in the inclusion space and becomes almost a base cloth swelled to a cleanable shape. At all points, it comes into contact with the inside from the inside and becomes a tension state, and the expansion stops.

Also, if the bag is made of a material that does not have elasticity, such as a float for swimming, when air is injected into the bag, it expands to the maximum expanded shape of the bag itself and becomes a substantially tensioned state and expands. Stops. In this case, since the expansion of the bag body in the inclusion space is not restricted by the maximum expansion shape of the base cloth, the base cloth may be made of a material having some elasticity.

Since the bag is deflated when air is not injected, the insertion opening that opens in the base cloth to insert the bag before air injection into the wiping body (inclusion space) has a small diameter. Is enough. Therefore, the wiping member can be formed by covering almost the entire outer periphery of the base cloth, so that a cleaning tool having a shock absorbing function can be provided without fear of damaging the floor or the wall.

When the head is attached to the wiping body, the air valve for injecting air attached to the bag body is arranged at the insertion opening, so the base cloth is provided with an opening for the air valve. It does not need to be provided separately. Therefore, it is possible to cover almost the entire outer circumference of the base cloth with a wiping piece to form a wiping body, and thus it is possible to provide a cleaning tool having a shock absorbing function without damaging a floor or a wall.

The head of the cleaning tool may be transported without being infused with air or may be transported with infused air when it is delivered from a factory to a customer or a store.
When delivering a head that is not injecting air, the bag is deflated without injecting air into the bag, so the head is not bulky and easy to deliver. Less likely to be damaged by etc.
When delivering the head in a state where air is infused, the head having the wiping body attached to the bag body is delivered. Since the bag itself functions as a bladder and functions as a cushion, there is an advantage that it is less likely to be damaged by impact during transportation.

According to the second aspect of the present invention, a conventional general cleaning tool such as a floor cleaning tool having a T-shaped head or a handy type cleaning tool having a single-bag type wiping member is used. The cleaning tool can be replaced with an air bag type cleaning tool having an ultra-light head, and it is possible to provide a cleaning tool that allows seniors to clean without burden.

Can be made easy and cheap. In the rental application of the cleaning tool, the customer has only the handle and can select the required head shape for each replacement. At that time, the head on which the wiping member is preliminarily mounted may be rented to the customer, so that the head is less likely to be damaged by impact or the like during delivery.

As the handle-side locking means and the bag-side locking means, various locking means such as hook-and-loop fasteners and hooks that can be detachably connected can be adopted.

According to the seventh aspect of the present invention, it is possible to provide the air bag type cleaning tool in which the plate is attached to the lower end of the handle and the handle side locking means is attached to the plate. By attaching the handle side locking means to the lower end portion of the handle via the plate, the handle and the head can be connected more reliably and can be detached. Further, when the lower end of the handle is provided with a rotating mechanism, a pressing body, etc., it may be difficult to attach the handle side locking means directly to the lower end of the handle due to the arrangement. In such a case, by attaching the handle side locking means to the lower end portion of the handle via the plate, it is possible to combine the attachment of the detachable handle with the rotation mechanism and the pressing function. ..

According to the eighth aspect of the present invention, the air bag type cleaning tool is provided with a pressing body protruding in the left and right directions at the lower end portion of the handle, and pressing the wiping body from the outside by the pressing body to prevent the bag body from warping. Can be provided. In the case where the bag consists of a left bag and a right bag, if the bag is long in the left-right direction, tilt the head during cleaning so that only one of the left and right wiping bodies strongly touches the floor surface. When used, it is difficult to prevent warping of both ends of the bag. Increasing the air pressure in the internal space can provide some curling prevention effect, but it also has its limitations. If a pressing body is provided at the lower end of the handle, the wiping body can be pressed from the outside to prevent the bag body from curling.

The ninth aspect and the tenth aspect of the present invention are integrated, and according to the ninth aspect, the base fabric is configured so that the inclusion space becomes a bottomed cylindrical space, and the opening end thereof is As the insertion port, the bag body is formed into a columnar bag body with both end surfaces closed, and a cylindrical hole with a bottom is formed on one end surface of the columnar bag body leaving an annular surface, and an air valve is formed on the annular surface. It is possible to provide an air bag type cleaning tool to which is attached. According to the tenth aspect, the bag-side locking means is attached to the bottomed cylindrical hole, the handle-side locking means is attached to the lower end of the operating handle, and the lower end of the handle is fixed. It is possible to provide an air bag type cleaning tool that is inserted into a bottomed cylindrical hole portion and detachably connects the handle side locking means to the bag body side locking means to incorporate the handle.

The cleaning tool is a cleaning tool having a columnar head and a handle and an air valve attached to one bottom surface side of the columnar body. By inserting and locking the lower end of the handle into the bottomed cylindrical hole, and by providing an air valve on the annular surface, the handle and the air valve can be compactly attached or arranged on one bottom surface, Since all the parts of the base cloth corresponding to the other bottom surface and side surface are covered with the wiping pieces and can be used as a wiping body, according to the present embodiment, there is little risk of damaging the floor or the wall, and shock absorbing performance is improved. It is possible to provide a cleaning tool having the same. This embodiment can be used for both a handy type and a floor type.

According to the eleventh aspect of the present invention, it is possible to provide an air bag type cleaning tool in which the air valve and the lower end portion of the handle are connected by a tube, and air is injected into the bag body from the handle by operating the handle. The handle itself has a function of injecting air into the bag body without using an external air injecting pump, so that air can be replenished.

An embodiment of a cleaning tool according to the present invention will be described below in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of an embodiment of the present invention, showing a handle 8, a head 3, and a wiping body 2. Only the lower end 8A of the handle 8 is shown, and the parts other than the lower end 8A are not shown. In this embodiment, when the handle 8 is a long handle, the air bag type cleaning tool 1 for the floor is used.
Further, when the handle 8 is short, it can be used as a handy type air bag type cleaning tool 1.
The head 3 includes a bag body 6, an air valve 30 provided on the bag body 6, and a bag body side locking means 64 provided on the outer periphery of the bag body 6. The bag body 6 hermetically surrounds the internal space 7.
The wiping body 2 includes a base cloth 4 made of a non-stretchable material, an insertion opening 21 provided in the base cloth 4, and a wiping piece 20 planted on substantially the entire outer circumference of the base cloth 4 excluding the insertion opening 21. Including. The space surrounded by the swollen wiping body 2 or the base cloth 4 is called an inclusion space 5.
The handle 8 has handle side locking means 80 at the lower end 8A of the handle.

FIG. 1 is an exploded view, and at the time of actual cleaning, the head 3 is used inside the wiping body 2, that is, in a state of being housed in the inclusion space 5. The bag body 6 is inserted into the wiping body 2 through the insertion opening 21 in a deflated state before injecting air, and is provided on the bag body side locking means 64 exposed from the insertion opening 21 and at the lower end portion 8A of the handle 8. The handle 8 is connected to the head 3 by locking the handle side locking means 80.
In the connected state, the air valve 30 is also exposed from the insertion port 21. By injecting air from the air valve 30, the bag body 6 swells until it is in a substantially tensioned state, and as a result, the base cloth 4 or the wiping body 2 that surrounds the bag body 6 inside is swollen and can be cleaned. It becomes a shape.

The above-mentioned injection of air may be performed before the connection of the handle 8. That is, after the bag body 6 is inserted into the wiping body 2 from the insertion opening 21 in a deflated state before injecting air, first, air is injected from the air valve 30 exposed from the insertion opening 21 to thereby inject the bag body 6. Swells to a substantially tensioned state, and as a result, the base cloth 4 or the wiping body 2 that surrounds the bag body 6 inside the wrapping space 5 swells into a cleanable shape, and then the bag exposed from the insertion port 21 The handle 8 may be connected to the head 3 by locking the handle side locking means 80 provided on the lower end portion 8A of the handle 8 to the body side locking means 64. According to the method, a specific one is selected from various types of wiping bodies 2 and bags 6 according to the customer's request, the bag body 6 is inserted into the wiping body 2 in the factory, and air is injected. The head 3 having a cleanable shape can be delivered to a customer, a store, or the like, and can be connected to a common handle 8 at the delivery destination.

FIG. 2 is a sectional view taken along the line AA of FIG. FIG. 2A shows a state in which the bag body 6 and the base cloth 4 are deflated before air injection, and FIG. 2B shows a state in which the bag body 6 and the base cloth 4 are inflated by the air injection to be in a cleanable shape. ..
The bag body 6 that expands due to the injection of air from the air valve 30 expands in the bag-shaped inclusion space 5 inside the base cloth 4 that forms the wiping body 2 (FIG. (2A)). Since the base cloth 4 is made of a material that does not have elasticity, the shape of the base cloth 4 when the inclusion space 5 expands to the maximum extent is fixed, and the base cloth 4 does not expand further. This shape is the maximum expansion shape of the base cloth 4. Even if the shape of the base cloth 4 does not reach the maximum expansion shape, the base cloth 4 is in the cleanable shape as long as the wiping body 2 maintains the cleanable shape. Here, when the bag body 6 is made of a stretchable material such as a rubber balloon, when air is injected into the bag body 6, the bag body 6 expands in the inclusion space 5 and expands to a cleanable shape. The base cloth 4 comes into contact with the base cloth 4 at almost all positions from the inside, and the expansion is stopped (FIG. 2B). 1 and 2, the cleanable shape is a substantially rectangular parallelepiped shape. However, the cleanable shape of the base cloth 4 is not limited to a substantially rectangular parallelepiped shape. It may be circular, rectangular, circular or oval.

When the bag body 6 is made of a material that does not have elasticity such as a float for swimming, when air is injected into the bag body 6, the bag body 6 inflates to the maximum expanded shape and is in a substantially tense state. And the expansion stops. In this case, since the expansion of the bag body 6 in the inclusion space 5 is not restricted by the maximum expansion shape of the base cloth 4, the base cloth 4 is made of a material having some elasticity. Good.

As the material forming the bag body 6, when the bag body 6 has elasticity, for example, natural rubber or synthetic rubber can be used. When the bag body 6 does not have elasticity, for example, vinyl chloride, polyethylene or the like can be used.
As the material for forming the base cloth 4, when the base cloth 4 does not have elasticity, for example, cotton cloth or non-stretchable woven cloth can be used. When the base cloth 4 has some elasticity, for example, a weakly elastic woven cloth containing fibers such as polyurethane can be used.

Since the bag body 6 is in a deflated state when air is not injected, the insertion opening 21 opened in the base cloth 4 in order to insert the bag body 6 before air injection into the wiping body (the inclusion space 5). , A small diameter is sufficient. Even when the base cloth 4 is made of a material having no elasticity, only the edge portion of the insertion port 21 of the base cloth 4 may be made of a material having elasticity. This is because the handle 8 and the air valve 30 exposed from the insertion opening 21 can be covered with the wiping body 2 by elastically contracting the edge portion of the insertion opening 21.
When the head 3 is attached to the wiping body 2, the air valve 30 for injecting air, which is attached to the bag body 6, is arranged at the insertion port 21, so that the base cloth 4 has an opening for the air valve. It is not necessary to provide it separately from the insertion port 21. Therefore, the wiping member 20 can be formed by covering almost the entire outer circumference of the base cloth 4 with the wiping piece 20, so that the air bag type cleaning tool 1 that does not damage floors and walls and has a shock absorbing function is provided. can do.

When replacing the wiping body 2 that is soiled due to use, when the air valve 30 exposed from the insertion opening 21 is operated to remove the air enclosed in the internal space 7, the bag body 6 shrinks and the base cloth 4 The bag body 6 can be pulled out from the inclusion space 5 surrounded by the through the insertion port 21, and the wiping body 2 and the bag body 6 can be easily separated. The pulled-out bag body 6 is removed from the handle 8 by releasing the engagement between the bag body side locking means 64 and the handle side locking means 80. In the rental application of the cleaning tool, the wiping body 2 and the bag body 6 can be collected from the customer's side without any trouble and can be washed and reused. Since air is released from the bag body 6 at the time of collection, the bag body 6 and the wiping body 2 are not bulky, can be easily transported, and are less likely to be damaged during transportation.

Here, the cleanable shape of the base cloth 4, the substantially tensioned state of the bag body 6, and the maximum expanded shape of the base cloth 4 or the bag body 6 will be described in more detail.
The state curves 32 and 33 of FIG. 2C and FIG. 2D both show that when the bag body 6 in a deflated state is inserted into the inclusion space 5 surrounded by the base fabric 4 and air is injected from the air valve 30, 6 is a graph showing how the volume V of the internal space 7 surrounded by the bag body 6 and the air pressure P (30B) change. FIG. 2C shows a state curve 32 when the bag body 6 is made of a stretchable material and the base cloth 4 is made of a non-stretchable material. FIG. (2D) shows a state in which the bag body 6 is made of a material having no elasticity and the base cloth 4 into which the bag body 6 is inserted has some elasticity or a material having no elasticity. Curve 33 is shown.

In the case of FIG. 2C, the pressure P of the air in the internal space 7 is equal to the atmospheric pressure P ₀ when the bag body 6 is initially deflated. When the volume V of the internal space 7 exceeds a certain value (volume of the state 32A) due to the injection of air, the pressure P increases as the volume V increases. At this time, the elastic force due to the elasticity of the bag body 6 gives an inward resultant force to each part of the bag body 6 to balance the pressure difference between the inside and the outside. The pressure P is not a linear function of the volume V but a monotonically increasing function. When air is further injected, the expansion of the base cloth 4 that accommodates the bag body 6 in the inclusion space 5 reaches the limit, and the base cloth 4 assumes the maximum expanded shape (state 32B). The volume V of the internal space 7 in the state 32B is V _m , and the pressure is P _m . When air is further injected to increase the volume V beyond V _m , the pressure P rapidly increases as shown in the graph because the base cloth 4 does not have elasticity.

In the case of FIG. 2C, the base cloth 4 has a cleanable shape only when the pressure P in the internal space 7 is close to P _m . This is because if the pressure P is too low, the shape of the wiping body 2 cannot be retained, and if the pressure P is too high, the shock absorbing property of the wiping body 2 is reduced and the risk of damage increases. For example, the cleaning is possible when the pressure P has a value within ±10% or ±20% of P _m , and depending on the material forming the bag body 6 and the base cloth 4 and the object and purpose of cleaning. Cleaning is possible even when the pressure P is within ±10% or ±20% of P _m . That is, the value of the pressure P at which the base cloth 4 has a cleanable shape has a range, and when the pressure P takes a value within the range close to P _m , the bag body 6 is expressed as being in a substantially tensioned state.
When the base cloth 4 has a cleanable shape and the pressure P is smaller than P _m , the shock absorbing performance is excellent, and the wiping body 2 easily conforms to the shape of the surface to be cleaned and is easily deformed. The air bag type cleaning tool 1 suitable for cleaning surfaces and gaps can be configured.

In the case of FIG. 2D, the pressure P of the air in the internal space 7 remains equal to the atmospheric pressure P ₀ for a while after the bag 6 is initially deflated and air is injected. When the volume V of the internal space 7 exceeds a certain value V ₁ (volume of the state 33A) due to the injection of air, the pressure P rapidly increases as the volume V increases. This is because the bag body 6 having no elasticity has expanded and reached the maximum expanded shape. When air is further injected, the expansion of the bag body 6 reaches the limit and the bag body 6 bursts (state 33B). The volume V of the internal space 7 in the state 33B is V ₂ , and the pressure is P ₂ .

In the case of FIG. 2D, in order for the base cloth 4 to have a cleanable shape, the pressure P in the internal space 7 must be higher than P ₀ to some extent and less than P ₂ to some extent. If the pressure P is too close to the atmospheric pressure P ₀ , the bag body 6 will be dented even with a slight impact and the shape of the wiping body 2 cannot be maintained. If the pressure P is too close to P ₂ , the impact absorbing property of the wiping body 2 will be reduced. This is because it lowers and the risk of breakage increases. That is, there is a range of values of the pressure P at which the base cloth 4 has a cleanable shape, and the range is from a certain value P ₃ larger than P ₀ to a certain value P ₄ smaller than P ₂ . Correspondingly, the volume V of the internal space 7 also takes a value within a range from a certain value V ₃ larger than V ₁ to a certain value V ₄ smaller than V ₂ (not shown). However, in the case of FIG. 2D, since the bag body 6 does not have elasticity, the values of V ₁ and V _2, and V ₃ and V ₄ do not differ greatly. The range of the pressure P and the range of the volume V in which the base cloth 4 has a cleanable shape differ depending on the materials forming the bag body 6 and the base cloth 4, the object of cleaning, and the purpose. When the pressure P takes a value within the above range, the bag body 6 is expressed as being in a substantially tensioned state.
When the base cloth 4 has a cleanable shape and the pressure P is close to the lower limit P _{3 of the} above range, the shock absorbing performance is good, and the wiping body 2 easily conforms to the shape of the surface to be cleaned and deforms. Therefore, the air bag type cleaning tool 1 suitable for cleaning uneven surfaces and gaps can be configured.

FIG. 3 is an external view of an embodiment of the present invention in which the bag body 6 of the head 3 has a tubular shape and the insertion port 21 is opened in the intermediate portion of the base cloth 4.
