  The present disclosure relates to a cleaning tool.

  A cleaning tool is commercially available that attaches a disposable cleaning body to the cleaning body mounting portion and performs wiping cleaning such as dust. As the cleaning tool, for example, a cleaning tool including a gripping part and an extendable and contractible arm part and a cleaning body attaching part is known.

  For example, in Patent Document 1, a slider provided at the tip of a small-diameter cylindrical body slides on an inner diameter part of a large-diameter cylindrical body in a telescopic rod-like tool formed by fitting a plurality of cylindrical bodies so as to be extendable and contractible. The slider includes a bottom portion that is fixedly attached to the small-diameter cylindrical body, and a skirt portion that extends in a short cylindrical shape from the outer edge of the bottom portion, and is provided along the axial direction of the outer peripheral portion of the bottom portion of the slider. The tubular body that expands and contracts by engaging the narrow groove and the wide groove provided along the axial direction of the skirt with the guide rib extending along the axial direction of the inner diameter part of the large-diameter tubular body.

In addition, since the skirt portion of the slider bends inward, the sliding mechanism, the locking mechanism at the time of extension, and the like tend not to be activated depending on the degree of extension of the telescopic bar-like tool.

  Therefore, the present disclosure includes a sliding portion that can slide the arm portion while suppressing the backlash of the arm portion in the deflection direction even when a force is applied in the deflection direction of the cleaning body mounting portion.

[Explanation of terms]
・ "Shrinkage" and "elongation"
In the present specification, “contracted form” and “extended form” relating to members (for example, the first arm part and the second arm part) constituting the cleaning tool are terms used for members that can be expanded and contracted.
Specifically, the “shrinking form” means a state where the expandable member is contracted to the maximum, and the “extension form” means a state where the expandable member is extended to the maximum.
The contracted form is related to a storage form of the cleaning tool described later, and the extended form is related to a cleaning form of the cleaning tool described later.

・ "Storage form" and "cleaning form" for cleaning tools
In this specification, the “storage form” related to the cleaning tool means a form that is adopted when the cleaning tool is stored. In general, the cleaning tool in the storage mode contracts all the extendable parts of the cleaning tool (to the storage mode), and when the cleaning tool has a rotating portion, the arm angle described later is minimized. is there.
In this specification, the “cleaning form” related to the cleaning tool means a form adopted when the cleaning tool is used. In general, when the cleaning tool includes a rotating part, the cleaning tool in the cleaning form should change the arm angle described later according to the location to be cleaned and clean the extendable part of the cleaning tool. It is in the state extended according to the part (in the member which can be expanded and contracted, an extended form is included). In addition, when cleaning a part close | similar to a user, it may be used without extending | stretching the part which can extend | stretch the cleaning tool.

・ "Front", "side" and "rear" for cleaning tools
In this specification, regarding the cleaning tool, in a state where the user holds the cleaning tool, a surface facing the user side is referred to as a front surface, and a surface opposite to the surface facing the user side is referred to as a back surface. A side surface means two surfaces between a front surface and a back surface.
When the cleaning tool is provided with a rotating part, the above-mentioned “front”, “side” and “back” have a configuration in which the cleaning tool is arranged substantially linearly, and preferably the arm angle θ of the rotating part is 180 degrees. Applied in the form.
In the cleaning tool 1 shown in the first embodiment, as shown in FIG. 1, the X axis, the Y axis, and the Z axis that are orthogonal to each other are shown, and the right side of the X axis is the front of the cleaning tool 1. Yes, the left side toward the X axis is the back surface of the cleaning tool 1, the far side toward the Y axis is the right side surface of the cleaning tool 1, and the near side toward the Y axis is the left side surface of the cleaning tool 1. .

・ "Inside" and "Outside"
In the present specification, “inward” and “outward” mean a direction approaching the axis and a direction away from the axis, respectively, in the object having the axis.

・ "Deflection direction" for the cleaning body mounting part
In the present specification, the “deflection direction” of the cleaning body mounting portion means the direction in which the cleaning body mounting portion is most flexible.
The cleaning body mounting portion may be used by being pressed against the surface to be cleaned when the surface to be cleaned is dirty, etc., and the cleaning body mounting portion bends to some extent in a direction orthogonal to the surface to be cleaned. It is configured as follows.

・ "Deflection direction" mentioned in relation to the arm part
When the cleaning body mounting portion bends in the deflection direction, the arm portion is likely to rattle in a predetermined direction orthogonal to the axis of the arm portion.
In this specification, when the cleaning tool does not include a rotating part, the "bending direction" referred to in relation to the rattling of the arm part is the same as the bending direction of the cleaning body mounting part. Is done. This is because the predetermined direction in which the arm portion is likely to rattle is the same as the deflection direction.

  Moreover, in this specification, when the cleaning tool is provided with a rotating part between the arm part provided with the gripping part and the cleaning body attaching part, it is mentioned in relation to the rattling of the arm part. The “deflection direction” is the same as the deflection direction of the cleaning body mounting portion in the state where the arm angle θ of the rotating portion is 180 degrees. The arm angle of 180 degrees is for defining the deflection direction referred to in relation to the arm portion, and is actually irrelevant whether or not the rotating portion can take the arm angle θ of 180 degrees. .

  When the cleaning tool is used when the arm angle of the rotating part is arbitrary, when the cleaning body mounting part (and the cleaning body) is pressed against the surface to be cleaned in the deflection direction, the cleaning body mounting part, The cleaning body receives a repulsive force in the direction opposite to the deflection direction from the surface to be cleaned. At that time, the arm portion including the gripping portion is orthogonal to the axial component force of the repulsive force in the direction of the axis of the arm portion and the orthogonal force of the repulsive force in the direction orthogonal to the axis of the arm portion. You will receive a direction force. The axial component force acts to expand and contract the arm portion, and the orthogonal component force acts to rattle the arm portion. The orthogonal component is the same as the deflection direction of the cleaning body mounting portion when the arm angle θ of the rotating portion is 180 degrees. The “deflection direction” mentioned in relation to the arm portion when the rotating portion is provided between the two portions is defined as described above.

・ "Outer surface cross section" and "Inner surface cross section"
In the present specification, the “outer surface cross-sectional shape” is a term used in an object having an axis and an outer shape, and the “outer surface cross-sectional shape” is a portion where a plane perpendicular to the axis and the outer shape of the object intersect. Means shape. In addition, the said outer surface cross-sectional shape is used also for a hollow part etc., for example, when a target object is a space | gap.
In this specification, “inner surface cross-sectional shape” is a term used in an object having an axis and an inner shape (gap), and “inner surface cross-sectional shape” refers to a plane orthogonal to the axis, the inner shape of the object, Means the shape of the intersection.

・ “Sliding function”, “Lock function when contracted” and “Lock function when extended”
In the present specification, a function of sliding the cylinders adjacent to the arm part, for example, the first cylinder and the second cylinder is referred to as “sliding function”. Further, the function of locking adjacent cylinders, for example, the first cylinder and the second cylinder in a contracted form is referred to as a “shrinkage lock function”, and adjacent cylinders, for example, the first cylinder and the first cylinder The function of locking the two cylinders in the extended form is referred to as “extension lock function”.
In addition, the mechanisms that exert the “sliding function”, “locking function when contracted”, and “locking function when extended” are respectively referred to as “sliding mechanism”, “locking mechanism when contracted”, and “locking mechanism when extended”. .

A sliding member comprising: an insertion portion connected to the second cylinder at the second base end portion; and a cylindrical portion configured to slide with the inner surface of the first cylinder. With
A pair of high deflection portions disposed on both sides in the deflection direction, and a pair of the cylindrical portions disposed at both ends in the deflection direction and less likely to bend inward than the pair of high deflection portions. With a low deflection part,
The said cleaning tool characterized by the above-mentioned.

  The cleaning tool includes a pair of high deflection portions, in which the cylindrical portions of the sliding member are disposed on both sides in the deflection direction and are more easily bent inward than the one low deflection portion, and both ends in the deflection direction. And a pair of low deflection portions that are disposed and are less likely to flex inward than the pair of high deflection portions. Therefore, even when a force in the deflection direction is applied to the arm portion when the cleaning body is used, the pair of low deflection portions of the cylindrical portion of the sliding member is not deformed in the deflection direction of the arm portion. Although it suppresses rattling, it can exhibit a rattling suppression function. Further, when the cleaning body is used, not only when the force in the deflection direction is not applied to the arm portion, but also when the force in the deflection direction is applied, a pair of the cylindrical portions of the sliding member. The high deflection portion can slide the arm portion, that is, can exert a sliding function.

[Aspect 2]
The cleaning tool according to aspect 1, wherein the cylindrical portion includes a slit portion extending in the direction of the axis between each of the pair of high deflection portions and each of the pair of low deflection portions.

In the cleaning tool, the cylindrical portion includes a slit portion extending in the direction of the axis of the arm portion between each of the pair of high deflection portions and each of the pair of low deflection portions. Each of the flexures and each of the pair of low flexures can easily perform their functions independently.
Further, the presence of the slit portion makes it easier for the cylindrical portion to change the shape of the cross section in the direction perpendicular to the axis of the arm portion. Therefore, when the first cylindrical body changes the shape of the inner surface between the proximal end side and the distal end side, for example, a taper such that the inner surface cross-sectional shape of the first cylindrical body decreases from the proximal end side to the distal end side. Even if it has, a cylindrical part and by extension, a sliding member can continue exhibiting the rattling suppression function and a sliding function.

[Aspect 3]

In general, when the arm portion has a long inner cross-sectional shape in the deflection direction of the cleaning body mounting portion, the arm portion has advantages such as being difficult to rotate in the circumferential direction, and being easy to grip the arm portion. There exists a tendency for an arm part to become easy to rattle in the deflection direction of a cleaning body attachment part.
In the cleaning tool, since the first cylindrical body has an inner cross-sectional shape that is long in the deflection direction of the cleaning body mounting portion, a pair of low deflection portions are disposed at both ends in the longitudinal direction of the inner surface of the first cylindrical body, And a pair of high deflection | deviation part will be arrange | positioned at the both ends of the transversal direction of the inner surface of a 1st cylinder. Therefore, in the cleaning tool, the pair of low deflection portions exerts a rattling suppression function in the deflection direction, which is a direction in which rattling is easy, and the pair of high deflection portions has an inner surface of the first cylindrical body. A sliding function can be exhibited with respect to both ends in the short direction.

[Aspect 6]
The first cylindrical body has a first proximal end portion from the proximal end and a first distal end portion from the distal end, and the cross-sectional shape of the inner surface of the first cylindrical body at the first distal end portion is first. The first end portion is smaller than the cross-sectional shape of the inner surface of the first cylinder at the base end, and each of the pair of low deflection portions does not contact the inner surface of the first cylinder at the first base end. The cleaning tool as described in any one of the aspects 1-5 comprised so that the said inner surface of the 1st cylinder in may be contact | connected.

In the cleaning tool, the inner surface cross-sectional shape of the first cylinder at the first distal end is smaller than the inner surface cross-sectional shape of the first cylinder at the first base end, and each of the pair of low deflection portions is the first base. Although it does not contact the inner surface of the first cylinder at the end, it is configured to contact the inner surface of the first cylinder at the first tip. Therefore, in the said cleaning tool, the inner surface of a 1st cylinder becomes easier to exhibit the rattling suppression function in the expansion | extension form of an arm part.
In addition, when the inner surface cross-sectional shape of the 1st cylinder in a 1st front-end | tip part is smaller than the inner surface cross-sectional shape of the 1st cylinder in a 1st base end part, the inner surface of a 1st cylinder is 1st base end. The case where it has a taper which becomes small from a part to the 1st tip part is mentioned.

[Aspect 7]
The first cylinder is a lock member connected to the first cylinder at the first base end, and includes a first lock part that is disposed in the hollow part and does not slide with the inner surface.

(Ii) the sliding member further includes a second locking portion connected to the cylindrical portion, which is disposed in the hollow portion and does not slide on the inner surface. (Iii) The first lock portion and the second lock portion are configured to lock by bringing the distance therebetween closer and unlock by moving the distance away from each other. Therefore, in the cleaning tool, the sliding member includes the cylindrical portion that exhibits the sliding function and the second lock portion that exhibits the locking function when contracted as different members. The sliding mechanism is less likely to deteriorate over time.

[Aspect 8]
The cleaning tool according to aspect 7, wherein one of the first lock portion and the second lock portion is a fitting projection, and the other is a fitting depression.

  In the cleaning tool, one of the first lock part and the second lock part is a fitting protrusion, and the other is a fitting recess, so that the lock mechanism is activated only by contracting the arm part. And it becomes easy to cancel | release a locking mechanism only by extending | stretching an arm part, As a result, the contraction form of an arm part can be fixed and cancel | released easily.

[Aspect 9]
The fitting protrusions are a pair of fitting protrusions, each of which extends in the direction of the axis, and a protrusion protruding outward from the tip of the extension. And the fitting recess is a pair of fitting recesses, each having a recess recessed outwardly. Cleaning tool.

The mechanism is easily released, and the contraction form of the arm portion can be easily fixed and released.

[Aspect 10]
The cleaning tool according to aspect 8 or 9, wherein the second lock portion is the fitting projection, and the fitting projection is based on one or both of the pair of low deflection portions.

  In the cleaning tool, since the second lock portion is a fitting projection, and the fitting projection is based on one or both of the pair of low deflection portions, it is caused by the difficulty in bending the pair of low deflection portions. Thus, the position of the fitting projection, in particular, the position in the direction perpendicular to the axis of the arm portion is difficult to shift, and the locking mechanism during contraction is easily activated and released easily.

[Aspect 11]

  Further, the rotating unit 7 does not include a member constituting the rotating unit 7, particularly a member that does not slide with the slide unit 701, in a region deeper than the bottom 705 in the depth direction DD. By doing so, although the structure of the rotation part 7 is simple, the slide part 701 can be operated as if pushed.

  The top portion 703 of the slide portion 701 includes a peripheral portion 745 disposed on the periphery of the top portion 703 and a protruding portion 747 surrounded by the peripheral portion 745. The protruding portion 747 protrudes by a height H on the opposite side of the bottom portion 105 from the peripheral edge portion 145. In other words, the protruding portion 747 is disposed at a depth position shallower by the height H than the peripheral edge portion 745 in the depth direction DD.

Further, since the top side gripping portion 741 is disposed at the same depth position as the peripheral edge portion 745 of the slide portion 701 disposed at the initial depth position: D ₀ in the depth direction DD, the top side gripping portion 741 is configured to be disposed at a depth position that is deeper by the height H than the position of the protruding portion 747 of the slide portion 701 at the initial depth position D ₀ in the depth direction DD. By doing so, it becomes easier for the user to push in the protruding portion 747 of the slide portion 701 without being affected by the top side gripping portion 741. Further, when the user pushes in the top portion 703 of the slide portion 701, the user's finger is less likely to be caught between the top side gripping portion 741 and the peripheral portion 745 of the slide portion 701.

  As described above, the first connecting portion 707 (the top side first connecting portion 711 and the bottom side first connecting portion 713) is connected to the second arm portion 9, and the second connecting portion 715 is connected to the first connecting portion 715. The arm portion 5 is connected. By doing so, for example, the user attaches the fingertip of the thumb of the left hand to the top 703 and the top side gripping part 741 of the slide part 701, attaches the index finger of the left hand to the bottom side gripping part 743, and the rest of the left hand When the second arm portion 9 is gripped, the top 703, the top side gripping portion 741 and the bottom side gripping portion 743 of the slide portion 701 rotate together with the second arm portion 9 and eventually the left hand. The sliding portion 701 is less susceptible to friction between the top portion 703, the top portion side gripping portion 741 and the bottom portion side gripping portion 743.

  In the cleaning tool of the present disclosure, when the arm portion includes three or more (3 ≦ n) cylinders, the (k + 1) th cylinder preferably includes the kth sliding member (k). Is an integer of 1 or more and (n-1) or less). This is because the entire arm portion can exhibit a sliding function.

  In the cleaning tool of the present disclosure, the kth sliding member includes the kth cylindrical portion along the inner surface of the kth cylindrical body, and includes a kth cylindrical portion axis and a kth circumferential direction. Preferably, the kth cylindrical portion includes a pair of kth high deflection portions that are easily bent inward, and a pair of kth low deflection portions that are less likely to be bent inward than the pair of kth high deflection portions. It is preferable.

The kth cylindrical portion includes a total of four kth slit portions having a predetermined width between each of the pair of kth high deflection portions and each of the pair of kth low deflection portions. It is preferable. This is because each of the pair of k-th high deflection portions and each of the pair of k-th low deflection portions can easily perform their functions independently. Moreover, it is because a cylindrical part becomes easy to change the shape of the cross section in the direction orthogonal to the axis line of an arm part.
In another embodiment of the present disclosure, the kth cylindrical portion includes a total of four kth slits between each of the pair of kth high deflection portions and each of the pair of kth low deflection portions. Instead of the part, a thin part of the material constituting the k-th cylindrical part, rubber or the like may be provided.

In addition, from the viewpoint of manufacturing, the k-th cylinder may have its outer cross-sectional shape and / or inner-surface cross-sectional shape changed along the axial direction of the k-th cylinder. For example, in the first cylinder, In some cases, the cross-sectional shape of the inner surface gradually decreases (has a taper) from the proximal end portion to the first distal end portion. Since the kth cylindrical portion of the kth sliding member includes the kth slit portion, the kth cylindrical portion can change the cross-sectional shape in the direction orthogonal to the kth cylindrical portion axis. Even if the k cylinder has a taper, the kth sliding member can exhibit a sliding function.
Further, the direction in which the k-th slit portion extends is not particularly limited, but from the viewpoint of changing the cross-sectional shape of the k-th cylindrical portion in the direction orthogonal to the k-th cylindrical portion axis, It is preferable to extend in the direction.

  The pair of kth high deflection portions are preferably disposed on both side portions in the deflection direction of the cleaning body mounting portion, and the pair of kth low deflection portions are disposed on both ends of the cleaning body mounting portion in the deflection direction. It is preferable. This is from the viewpoint of the effect of the present disclosure.

The cross-sectional shape (inner surface cross-sectional shape, outer surface cross-sectional shape) of the k-th cylinder in the direction orthogonal to the direction of the arm portion axis is arbitrary, and examples thereof include a circle, an ellipse having a major axis and a minor axis.
When the cross-sectional shape of the k-th cylinder is an ellipse, the k-th high deflection portion is disposed at both ends in the minor axis direction of the k-th cylinder, and the k-th low deflection portion is the k-th deflection portion. It is preferable that it is arrange | positioned at the both ends of the long diameter direction of a cylinder. This is because the (k + 1) -th cylinder is less likely to rattle with respect to the k-th cylinder and is difficult to rotate in the k-th circumferential direction. In addition, since the k-th high deflection portion can contact the inner surface of the k-th cylinder closer to the plane than the k-th low deflection portion, the k-th high deflection portion can more easily exert a sliding function. Because.

  Each of the pair of kth low deflection portions extends in the kth circumferential direction and is configured to slide with the inner surface of the kth cylindrical body, and the kth low deflection portion circumferential extension portion, and the kth cylinder It is preferable to include one of the k-th low deflection portion extending in the axial direction and configured to slide with the inner surface of the k-th cylinder, and both. More preferably. This is because the pair of kth low deflection portions, and by extension, the sliding members can further exhibit the sliding function.

It is preferable. This is because the contraction form of the arm portion can be easily fixed and released. The same applies to the pair of lock portions described above.

  One of the first lock part and the second lock part is preferably a fitting protrusion, and the other is a fitting recess. This is because the lock mechanism operates only by contracting the arm portion, and the lock mechanism can be easily released only by extending the arm portion, and as a result, the contraction form of the arm portion can be easily fixed and released. In the pair of lock portions described above, it is preferable that one is a fitting projection and the other is a fitting recess.

  It is preferable that the second lock portion is a fitting projection, and the base point of the fitting projection is a low deflection portion. Due to the low flexibility of the low deflection part, the position of the projection for fitting is difficult to shift, in particular, it is difficult to shift in the direction approaching or moving away from the axis of the cylindrical part, and the viewpoint that the lock function during contraction is surely easily exhibited. Because.
