Definitions
- the present invention relates to a cleaning tool.
- Patent Document 1 discloses a cleaning tool including a shaft portion and a fiber lump (cleaning portion) attached to the tip portion of the shaft portion.
- the cleaning unit is formed by compressing a predetermined amount of fibers.
- an elastomer is known as a material that can be used for forming a cleaning portion for cleaning minute gaps without causing the problem of fuzzing.
- the cleaning part formed of this elastomer does not cause fuzz and effectively removes dirt in the minute gaps by friction generated between the cleaning part and the object to be cleaned.
- the improvement of the insertion property of the cleaning portion into the minute gap is insufficient. Specifically, if the tip of the cleaning unit comes into contact with the object to be cleaned when the cleaning unit is inserted into a minute gap, the depth of the cleaning unit can be further increased by inserting the cleaning unit toward the back of the gap. An operation for changing the insertion direction (the posture of the shaft portion) with respect to the gap of the cleaning portion is required so that the insertion into the space is allowed. Since this operation is required every time the tip of the cleaning unit comes into contact with the object to be cleaned, it is very difficult to insert the cleaning unit to the back of the gap.

- the force required to press the guide portion 24 from the insertion end portion 12a side to the base end portion 12b side until the guide portion 24 is displaced by 5.0 mm in the axial direction while being deformed is 1.0 N.
- the elastomer one having an A40 Shore hardness is used so as to be 8.0 N or less.
- the pressing force includes a force necessary to elastically deform the guide portion 24 made of the elastomer in addition to a force necessary to bend and deform the shaft portion 12.
- the micro protrusion 25 provided at the tip of the guide portion 24 improves the insertion property of the cleaning portion 20 into the gap S. Specifically, when the minute projection 25 comes into contact with the object T to be cleaned, the minute projection 25 guides the displacement direction of the guide portion 24 so that the guide portion 24 is elastically deformed toward the back of the gap S. Further, it becomes easier to insert the cleaning unit 20 into the gap S.

It is preferable to have a shape that gradually reduces the outer shape of the bristles 27 as it goes on. Further, the brush bristles 27 fall when the bristles 27 come into contact with the object to be cleaned T when being inserted into the gap S.
- the brush bristle group may include first curved brush bristles 27a and second curved brush bristles 27b.
- the first curved bristle 27a has a shape that gradually curves from the base end part 12b side toward the insertion end part 12a side toward the outside from the cleaning part main body 22 in the axis orthogonal direction.
- the second curved brush bristles 27b have a shape that gradually curves from the insertion end portion 12a side toward the base end portion 12b side toward the outside from the cleaning portion main body 22 in the axis orthogonal direction.

- the guide part when the protruding dimension of the guide part is set to 0.6 or more times the dimension of the insertion end part in the direction perpendicular to the axis, the guide part with respect to the dimension in the direction perpendicular to the axis of the insertion end part is elastically deformed. Since the ratio of the amount of displacement of the guide part is sufficiently large, the guide part is effectively guided toward the back of the gap as the shaft part is inserted after the guide part contacts the object to be cleaned. On the other hand, by setting the projecting dimension of the guide part to be four times or less the dimension of the insertion end part in the axis-perpendicular direction, the guide part has a relatively long projecting dimension. A decrease, that is, a decrease in insertability into the gap of the guide portion is suppressed.
- the protrusion dimension of the said guide part is set to 0.10 mm or more and 1.2 mm or less, and the dimension of the said axial direction of the said shaft part is set to 10 mm or more,
- the said cleaning In a state in which a portion of the tool that is 10 mm away from the distal end of the guide portion toward the proximal end portion is fixed, the guide portion is moved in the axial direction with elastic deformation of the guide portion and bending deformation of the shaft portion.
- the elastomer shore is adjusted so that a pressing force required to press the guide portion from the insertion end portion side toward the base end portion side is 5.0 N or less and 8.0 N or less until the displacement is 5.0 mm. It is preferable that the hardness is set.
- the pressing force includes a force necessary to elastically deform the guide portion made of the elastomer in addition to a force necessary to bend and deform the shaft portion.
- the deformation failure (the guide property to the back of the clearance of the cleaning unit main body by the guide unit is impaired) is suppressed.
- the cleaning unit further includes a minute protrusion provided at a tip of the guide unit and having an outer shape smaller than the outer shape of the guide unit.
- the microprotrusion guides the displacement direction of the guide portion so that the guide portion is elastically deformed toward the back of the gap. Insertion into the gap is further facilitated.
- the cleaning unit further includes a brush bristle group including a plurality of brush hairs each having a shape projecting outward in the axis-orthogonal direction from the outer peripheral surface of the cleaning unit body,
- the brush bristle group has a first curved brush bristle that has a shape that gradually curves from the base end side toward the insertion end side as it goes outward from the cleaning unit main body in the direction orthogonal to the axis, and the shaft It is preferable to include second curved brush bristles having a shape that gradually curves from the insertion end side toward the base end side as it goes outward from the cleaning unit main body in the orthogonal direction.
- the bristle group includes first curved brush hairs having a shape that gradually curves from the proximal end side toward the insertion end side as it goes outward from the cleaning unit body, and outward from the cleaning unit body.
- the second curved brush bristles having a shape that gradually curves from the insertion end side toward the base end side as it goes toward the first end. The second curved brush bristles effectively clean the gap or the object to be cleaned during the extraction.
- the brush bristle group includes the first curved brush bristle and the second curved brush bristle, so that cleaning is performed as compared with the case where the brush bristle group includes only one of the first curved brush bristle and the second curved brush bristle.
- the insertion resistance felt by the operator when inserting the part into the gap and the pulling resistance felt by the operator when pulling the cleaning part out of the gap become substantially uniform. For this reason, the cleaning operation by the operator becomes easy.
- the first curved bristle and the second curved bristle are designed such that brush bristle having a shape extending linearly outward from the outer peripheral surface of the cleaning unit main body in the direction perpendicular to the axis is formed.
- Brush hair molded by a mold, and gradually from the base end side to the insertion end side or from the insertion end side to the base end as it goes outward from the cleaning unit body after releasing from the mold Including those that have a shape that curves toward the part side.
- the insertion end portion and the guide portion are each formed in a hemispherical shape that curves so as to protrude outward in the axial direction, and the radius of the guide portion. Is preferably set to 1.1 times to 8 times the radius of the insertion end, more preferably 1.1 times to 4 times, and more preferably 1.2 times to 2 times. More preferably, it is set to less than twice.
- the guide part guides the cleaning part body to the gap when the cleaning part is inserted into the gap. Increases effectiveness.

Abstract
La présente invention concerne un dispositif de nettoyage équipé de : une partie de tige (12) ayant une section d'extrémité d'insertion (12a) et une section d'extrémité de base ; et une partie de nettoyage comprenant un élastomère et capable de nettoyer un espacement. La partie de tige (12) est formée de manière à être capable de flexion et de déformation de manière à permettre le déplacement de la section d'extrémité d'insertion (12a) par rapport à la section d'extrémité de base dans une direction perpendiculaire à la tige. La partie de nettoyage comporte un corps de partie de nettoyage (22) et une partie de guidage (24) pour faire saillie plus loin vers l'extérieur dans la direction axiale que la section d'extrémité d'insertion (12a), et guider l'insertion du corps de partie de nettoyage (22) dans un espacement. La dimension de saillie (t2) de la partie de guidage (24) depuis la section d'extrémité d'insertion (12a) est égale ou supérieure à l'épaisseur (t1) du corps de partie de nettoyage (22), et la partie de guidage (24) est formée de manière à être capable de déformation élastique de manière à être déplacée par rapport à la section d'extrémité d'insertion (12a) dans une direction perpendiculaire à la tige.
