基板部３ａの表面の四隅には、清掃布を保持するための保持部９がそれぞれ配置されている。保持部９の上部は基板部３ａ上に形成された台形部９ａとされ、台形部９ａは下方に延在する空箱状の空隙部９ｂを有している。空隙部９ｂの上面つまり台形部９ａの上面には、略矩形状の開口部９ｃが開口され、開口部９ｃの一部のＹ方向の外側には、略半円形状の切込部９ｄが設けられている。 Holding portions 9 for holding cleaning cloths are arranged at the four corners of the surface of the substrate portion 3a. The upper portion of the holding portion 9 is a trapezoidal portion 9a formed on the substrate portion 3a, and the trapezoidal portion 9a has an empty box-like space portion 9b extending downward. A substantially rectangular opening 9c is formed in the upper surface of the cavity 9b, that is, the upper surface of the trapezoidal portion 9a, and a substantially semicircular cutout 9d is provided outside a part of the opening 9c in the Y direction. It is

開口部９ｃ内には、この開口部９ｃを閉塞するように、開口部９ｃとほぼ同形の板体状の蓋部９ｅが配置され、切込部９ｄに相当する位置には、押込部９ｆが蓋部９ｅと一体に蓋部９ｅよりも一段と低く形成されている。 A plate-shaped cover portion 9e having substantially the same shape as the opening portion 9c is arranged in the opening portion 9c so as to close the opening portion 9c, and a push-in portion 9f is provided at a position corresponding to the cut portion 9d. It is formed integrally with the lid portion 9e so as to be much lower than the lid portion 9e.

また、図２の斜視図に示すように、蓋部９ｅの両側には側板部９ｇがＬ字状に折り曲げられており、これらの側板部９ｇの外側には突起９ｈが形成されている。蓋部９ｅを開口部９ｃに取り付ける際に、蓋部９ｅの両側に設けられた側板部９ｇの突起９ｈを、空隙部９ｂの両側の側壁に上下に設けた溝部９ｉに押し込むことで、最終的に溝部９ｉの下端に設けた凹部９ｊに嵌入される。なお、突起９ｈ及び凹部９ｊは、蓋部９ｅ及び空隙部９ｂに対して、逆に配置するようにしてもよい。 Further, as shown in the perspective view of FIG. 2, side plate portions 9g are bent into L-shapes on both sides of the lid portion 9e, and projections 9h are formed on the outsides of these side plate portions 9g. When the lid portion 9e is attached to the opening portion 9c, the protrusions 9h of the side plate portions 9g provided on both sides of the lid portion 9e are pushed into the groove portions 9i provided vertically on both side walls of the gap portion 9b. is fitted into a recess 9j provided at the lower end of the groove 9i. Note that the protrusion 9h and the recess 9j may be reversely arranged with respect to the lid portion 9e and the gap portion 9b.

空隙部９ｂの側壁の下端には、空隙部９ｂ底から上方に突出し、上端が円弧状に凹んだ突出部９ｋが設けられている。溝部９ｉを挟んだ突出部９ｋの上端に、側板部９ｇの円弧状の下端が当接しながら、凹部９ｊに軸支された突起９ｈを中心に蓋部９ｅが回動可能とする構造となっている。 At the lower end of the side wall of the cavity 9b, there is provided a protruding part 9k which protrudes upward from the bottom of the cavity 9b and whose upper end is recessed in an arc shape. While the arc-shaped lower end of the side plate portion 9g abuts against the upper end of the protruding portion 9k sandwiching the groove portion 9i, the lid portion 9e can rotate around the projection 9h pivotally supported by the recessed portion 9j. there is

蓋部９ｅの裏面と空隙部９ｂの底部の台座９ｌとの間に、例えばコイルスプリングから成るばね部９ｍが配置され、ばね部９ｍは蓋部９ｅを押し上げるように付勢している。従って、ばね部９ｍは常に蓋部９ｅが開口部９ｃを閉塞する方向に付勢力を有している。 A spring portion 9m made of, for example, a coil spring is arranged between the rear surface of the lid portion 9e and the pedestal 9l at the bottom of the space portion 9b, and biases the lid portion 9e upward. Therefore, the spring portion 9m always exerts an urging force in the direction in which the lid portion 9e closes the opening portion 9c.

更に、蓋部９ｅの後部には板状の制止部９ｎが設けられており、蓋部９ｅが開口部９ｃを閉塞している場合に、制止部９ｎは空隙部９ｂの後壁に接し、蓋部９ｅが開口部９ｃよりも上方に回動しないように制止する役割を果たしている。なお、板状の制止部９ｎを設けずに、蓋部９ｅの後辺部を制止部９ｎとして空隙部９ｂの後壁に接するようにして、蓋部９ｅの回動を制止するようにしてもよい。 Further, a plate-like blocking portion 9n is provided at the rear portion of the lid portion 9e. When the lid portion 9e blocks the opening portion 9c, the blocking portion 9n contacts the rear wall of the gap portion 9b, It serves to prevent the portion 9e from rotating upward from the opening portion 9c. Alternatively, instead of providing the plate-shaped stopping portion 9n, the rear side of the lid portion 9e may be used as the stopping portion 9n to come into contact with the rear wall of the gap portion 9b so as to stop the rotation of the lid portion 9e. good.

また、開口部９ｃの周囲のＹ方向の外側であって、略半円形状の切込部９ｄを囲む上面板９ｏの裏面には、清掃シートＳの滑りを防止するために、複数の小突起９ｐが形成されている。 Further, a plurality of small projections are provided on the back surface of the upper surface plate 9o surrounding the substantially semicircular cutout 9d to prevent the cleaning sheet S from slipping. 9p is formed.

蓋部９ｅの押込部９ｆを指で内方に押すと、図５の左側に示すように、蓋部９ｅはばね部９ｍによる上方への付勢力に抗して、支点である突出部９ｋを中心に下方に回動して沈み込む。押込部９ｆから指を離すと、蓋部９ｅはばね部９ｍにより上昇するが、制止部９ｎが空隙部９ｂの後壁に接することにより、蓋部９ｅは開口部９ｃの位置に留まり、開口部９ｃの上側に飛び出ることはない。 When the push-in portion 9f of the lid portion 9e is pushed inward with a finger, as shown on the left side of FIG. It rotates downward to the center and sinks. When the finger is released from the push-in portion 9f, the lid portion 9e is lifted by the spring portion 9m. It does not protrude above 9c.

ヘッド部３に継手部４を取り付けるには、回動部５の一対の第１の軸部５ｂを、ヘッド部３の起立片３ｄの一対の第１の軸孔部３ｅに挿入し、回動部５がＸ方向を中心としてＹ方向に回動するように取り付ける。次に、ロック部６を回動部５上に配置し、ロック部６の穴部６ａに回動部５の突部５ｄを挿入すると共に、回動部５の突部５ｄ、板体部５ａ間にロック部６の壁部６ｃを押し込んで、ロック部６を回動部５に取り付ける。 In order to attach the joint portion 4 to the head portion 3, the pair of first shaft portions 5b of the rotating portion 5 are inserted into the pair of first shaft holes 3e of the standing pieces 3d of the head portion 3, and then rotated. The part 5 is attached so as to rotate in the Y direction around the X direction. Next, the locking portion 6 is placed on the rotating portion 5, the protrusion 5d of the rotating portion 5 is inserted into the hole portion 6a of the locking portion 6, and the protrusion 5d of the rotating portion 5 and the plate portion 5a are inserted. The lock portion 6 is attached to the rotating portion 5 by pushing the wall portion 6c of the lock portion 6 therebetween.

続いて、ロック部６の第２の軸部６ｄを、係合部７のアーム部７ｂの第２の軸孔部７ｃに挿入することで、係合部７がロック部６にＹ方向を中心としてＸ方向に回動するようになる。最後に、回動部５の第１の貫通孔５ｃ、ロック部６の第２の貫通孔６ｅ、係合部の第３の貫通孔７ｅにボルト８を挿通して、ボルト８の外ねじを係合部の第３の貫通孔７ｅの内ねじに螺合してボルト８を固定する。ボルト８で固定することで、回動部５、ロック部６、係合部７は一体化する。 Subsequently, by inserting the second shaft portion 6d of the lock portion 6 into the second shaft hole portion 7c of the arm portion 7b of the engagement portion 7, the engagement portion 7 is attached to the lock portion 6 in the Y direction. As a result, it rotates in the X direction. Finally, the bolt 8 is inserted through the first through hole 5c of the rotating portion 5, the second through hole 6e of the locking portion 6, and the third through hole 7e of the engaging portion, and the external thread of the bolt 8 is tightened. The bolt 8 is fixed by screwing it into the inner thread of the third through hole 7e of the engaging portion. By fixing with the bolt 8, the rotating portion 5, the locking portion 6, and the engaging portion 7 are integrated.

継手部４の組立てが完了すると、柄部２はヘッド部３に対して、回動部５の第１の軸部５ｂによりＹ方向に任意の角度範囲で回動できると共に、ロック部６の第２の軸部６ｄによりＸ方向に回動する。即ち、柄部２は前後方向、左右方向、つまり任意の方向、角度で、伏倒、起立することが可能となる。従って、床面等の狭い個所等に、ヘッド部３を挿入して、清掃シートにより隅々まで掃除することができることになる。 When the joint portion 4 is assembled, the handle portion 2 can be rotated in an arbitrary angle range in the Y direction with respect to the head portion 3 by the first shaft portion 5b of the rotating portion 5. 2 is rotated in the X direction by the shaft portion 6d. That is, the handle 2 can be laid down and raised in the front-rear direction and the left-right direction, that is, in any direction and at any angle. Therefore, it is possible to insert the head part 3 into a narrow space such as a floor surface and clean every corner with the cleaning sheet.

清掃具１の使用に際しては、図６に示すように、例えば市販の横３０ｃｍ、縦２０ｃｍ、厚み０．５ｍｍ程度の不織布から成る清掃シートＳをヘッド部３に取り付けることが可能である。なお、実施例においては、取り付ける清掃布として上述の清掃シートＳを用いて説明しているが、清掃シートＳよりも厚みの大きな雑巾等を用いることもできる。 When using the cleaning tool 1, as shown in FIG. 6, it is possible to attach a commercially available cleaning sheet S made of nonwoven fabric having a width of 30 cm, a length of 20 cm, and a thickness of 0.5 mm to the head portion 3, for example. In the embodiment, the cleaning sheet S described above is used as the cleaning cloth to be attached.

清掃シートＳを取り付けるには、一方側の端辺部を、基板部３ａの一方側の保持部９内に押し込んで、摺掃部３ｂの下面を覆うように一巡させて、清掃シートＳの他側の端辺部を、基板部３ａの他方側の保持部９に押し込むことで、清掃シートＳを基板部３ａに固定することができる。 In order to attach the cleaning sheet S, one edge portion of the substrate portion 3a is pushed into the holding portion 9 on one side of the substrate portion 3a so as to cover the lower surface of the cleaning portion 3b. is pushed into the holding portion 9 on the other side of the substrate portion 3a, the cleaning sheet S can be fixed to the substrate portion 3a.

つまり、清掃シートＳを保持部９上に置いて、蓋部９ｅの押込部９ｆを清掃シートＳと共にばね部９ｍに抗して指で押し込み、清掃シートＳを空隙部９ｂ内に押し込み、蓋部９ｅと開口部９ｃとの間の間隙で、ばね部９ｍの付勢力により清掃シートＳを挟着する。なお、その際に開口部９ｃの裏面に設けた小突起９ｐにより、清掃シートＳに摩擦力が付与され更に抜け難くなる。 That is, the cleaning sheet S is placed on the holding portion 9, and the push-in portion 9f of the cover portion 9e is pushed against the spring portion 9m together with the cleaning sheet S by a finger to push the cleaning sheet S into the space portion 9b. The cleaning sheet S is sandwiched between the gap 9e and the opening 9c by the biasing force of the spring portion 9m. At this time, a frictional force is applied to the cleaning sheet S by the small projections 9p provided on the back surface of the opening 9c, making it even more difficult to remove.

そして、清掃具１の柄部２を持って、ヘッド部３を床面、壁面等を摺動させることで、清掃シートＳに塵芥が付着する。十分な塵芥が清掃シートＳに付着すると、保持部９から清掃シートＳを蓋部９ｅの押込部９ｆを指で押して、清掃シートＳを取り外す。取り外した清掃シートＳの裏面がまだ未使用であれば、表裏を反転して、再度、保持部９に取り付けて使用することもできる。清掃シートＳの両面に十分な塵芥が付着した後に、この清掃シートＳを取り外して破棄し、新しい清掃シートＳをヘッド部３に取り付ける。 Dust adheres to the cleaning sheet S by holding the handle 2 of the cleaning tool 1 and sliding the head 3 on a floor surface, a wall surface, or the like. When sufficient dust has adhered to the cleaning sheet S, the cleaning sheet S is removed from the holding portion 9 by pressing the pushing portion 9f of the lid portion 9e with a finger. If the back surface of the removed cleaning sheet S is still unused, it can be turned upside down and attached to the holding portion 9 again for use. After sufficient dust has adhered to both sides of the cleaning sheet S, the cleaning sheet S is removed and discarded, and a new cleaning sheet S is attached to the head part 3. - 特許庁

本発明に係る清掃具１によれば、清掃布を保持する保持部９にばね部９ｍを用いることで、保持部９は、厚さが異なる清掃シートＳや雑巾を係止できると共に、長期間使用しても清掃布に対する挟持力が低下することがない。 According to the cleaning tool 1 of the present invention, by using the spring portion 9m in the holding portion 9 that holds the cleaning cloth, the holding portion 9 can hold the cleaning sheet S and the rag having different thicknesses and can be held for a long period of time. Even if it is used, the clamping force against the cleaning cloth does not decrease.
