Description

本発明は、基台にブラシ毛やスポンジ等の清掃部が設けられている清掃具の緩衝技術に関する。   The present invention relates to a cushioning technique for a cleaning tool in which a cleaning unit such as a brush hair or a sponge is provided on a base.

この種の清掃具では、基台の外周面が清掃対象箇所及びその周囲に存在するタイルや鏡等に衝突することに起因する損傷を抑制することが要望されている。
そのため、従来では、基台の外周面よりも外方に突出する緩衝部分と基台の樹脂成形時に埋設状態で固着される埋設部分とを備えた環状の弾性緩衝体を製作し、この弾性緩衝体を基台の成形金型内に装着した状態でのインサート成形により、基台と弾性緩衝体とを一体化していた（例えば、特許文献１参照）。 In this type of cleaning tool, there is a demand for suppressing damage caused by the outer peripheral surface of the base colliding with a portion to be cleaned and tiles, mirrors, and the like existing therearound.
For this reason, conventionally, an annular elastic buffer body having a buffer portion protruding outward from the outer peripheral surface of the base and an embedded portion fixed in an embedded state during resin molding of the base is manufactured. The base and the elastic buffer are integrated by insert molding in a state where the body is mounted in the base mold (see, for example, Patent Document 1).

従来の清掃具では、前記弾性緩衝体を基台の成形金型内に装着した状態でのインサート成形により、基台と弾性緩衝体とを一体化しているため、基台の成形時の工程数が増加するとともに、成形金型自体が複雑化するため、清掃具の製造コストが高騰化していた。   In the conventional cleaning tool, the base and the elastic buffer are integrated by insert molding in a state where the elastic buffer is mounted in the molding die of the base. Since the molding die itself becomes complicated, the manufacturing cost of the cleaning tool has increased.

本発明は、上述の実状に鑑みて為されたものであって、その主たる課題は、衝突時の弾性緩衝体の離脱を抑制した状態で所期の衝突緩衝機能を良好に発揮することができ、且つ、製造コストの低廉化を図ることのできる清掃具を提供する点にある。   The present invention has been made in view of the above-described actual situation, and the main problem is that the desired collision buffering function can be satisfactorily exhibited in a state where the detachment of the elastic buffer during the collision is suppressed. And it exists in the point which provides the cleaning tool which can aim at the reduction of manufacturing cost.

本発明による第１の特徴構成は、清掃部を備えた基台の外周面に、これの全周にわたって外方に開口する環状の装着溝が形成され、この装着溝には、基台の外周面よりも外方に突出する環状の弾性緩衝体が、当該弾性緩衝体の弾性復元力で前記装着溝の内面に密着する状態で嵌合装着され、前記基台の装着溝が、細幅の底面側装着溝とこれよりも広幅の表面側装着溝とから構成されているとともに、前記弾性緩衝体の嵌合部が、前記底面側装着溝に嵌合装着される細幅の底面側嵌合部と、前記表面側装着溝に嵌合装着される広幅の表面側嵌合部とから構成されている点にある。 According to a first characteristic configuration of the present invention, an annular mounting groove that opens outward is formed on the outer peripheral surface of the base including the cleaning portion, and the outer periphery of the base is formed in the mounting groove. A ring-shaped elastic buffer projecting outward from the surface is fitted and mounted in a state of being in close contact with the inner surface of the mounting groove by the elastic restoring force of the elastic buffer, and the mounting groove of the base is narrow. A bottom side fitting groove, and a fitting part of the elastic buffer is fitted into the bottom side fitting groove. It is in the point comprised from the joint part and the wide surface side fitting part fitted and mounted | worn by the said surface side mounting groove .

上記構成によれば、前記基台の外周面に形成された装着溝に弾性緩衝体を嵌合装着した状態では、この弾性緩衝体の表面側は基台の外周面よりも外方に突出し、且つ、弾性緩衝体の嵌合部側は、当該弾性緩衝体の弾性復元力で装着溝の内面に密着しているから、他物との衝突時の衝撃力を緩和することができるとともに、この衝突時の離脱方向の外力に対して弾性緩衝体を装着溝に嵌合装着した状態に維持することができる。   According to the above configuration, in a state where the elastic buffer is fitted and mounted in the mounting groove formed on the outer peripheral surface of the base, the surface side of the elastic buffer protrudes outward from the outer peripheral surface of the base, And since the fitting part side of the elastic buffer is in close contact with the inner surface of the mounting groove by the elastic restoring force of the elastic buffer, the impact force at the time of collision with other objects can be reduced, and this The elastic buffer can be maintained in a state of being fitted and mounted in the mounting groove against an external force in the direction of separation at the time of collision.

しかも、前記基台と弾性緩衝体とを各別に製造して、基台の装着溝に弾性緩衝体を嵌合装着するだけであるから、従来に比して前記基台の成形金型の簡素化と成形時の工程数の削減とを図ることができる。   Moreover, since the base and the elastic buffer are manufactured separately and the elastic buffer is simply fitted and mounted in the mounting groove of the base, the molding die of the base is simpler than before. And reduction in the number of processes during molding.

したがって、衝突時の弾性緩衝体の離脱を抑制した状態で所期の衝突緩衝機能を良好に発揮することのできる清掃具を製造コスト面で有利に提供することができる。   Therefore, it is possible to advantageously provide a cleaning tool that can satisfactorily exhibit the desired collision buffer function in a state where the elastic buffer body is prevented from being detached at the time of collision.

また、上記構成によれば、前記装着溝の細幅の底面側装着溝と広幅の表面側装着溝との間に存在する段差面から弾性緩衝体の表面までの緩衝厚み及び緩衝幅が大きくなり、例えば、前記基台の装着溝及び弾性緩衝体の嵌合部が、本発発明の細幅の底面側装着溝と同じ幅に形成されている場合に比して、緩衝機能を高めることができるとともに、前記広幅の表面側嵌合部が装着溝の中間深さにまで達するから、弾性緩衝体をそれに作用する捩れ等の離脱力に抗して嵌合装着状態に良好に維持することができる。 Further , according to the above configuration, the buffer thickness and the buffer width from the step surface existing between the narrow bottom side mounting groove and the wide surface side mounting groove of the mounting groove to the surface of the elastic buffer body are increased. For example, the buffering function can be improved as compared with the case where the mounting groove of the base and the fitting portion of the elastic buffer are formed to have the same width as the narrow bottom mounting groove of the present invention. In addition, since the wide surface side fitting portion reaches the intermediate depth of the mounting groove, the elastic buffer body can be well maintained in the fitted mounting state against the detachment force such as torsion acting on it. it can.

本発明による第２の特徴構成は、前記基台の装着溝における表面側装着溝のうち、他物との衝突頻度が高い部位の溝部が他の部位の溝部よりも広幅に構成され、この広幅表面側装着溝部に対応する前記弾性緩衝体の表面側嵌合部の一部が、前記広幅表面側装着溝部に密着状態で嵌合装着可能な広幅表面側嵌合部分に形成されている点にある。 According to a second characteristic configuration of the present invention, among the surface side mounting grooves in the mounting groove of the base, the groove portion of the portion having a high collision frequency with another object is configured to be wider than the groove portion of the other portion. A part of the front-side fitting portion of the elastic buffer corresponding to the front-side mounting groove is formed in a wide-surface-side fitting portion that can be fitted and mounted in close contact with the wide-surface mounting groove. is there.

上記構成によれば、他物との衝突頻度が高い部位の装着溝の表面側装着溝における溝幅及びこれに密着状態で嵌合装着される弾性緩衝体の表面側嵌合部の幅が他の部位よりも広幅に構成されているため、前記装着溝の表面側装着溝及び弾性緩衝体の表面側嵌合部の幅が全周で同一幅に構成されている場合に比して、他物との衝突頻度が高い部位での緩衝機能を高めることができるとともに、装着溝と弾性緩衝体との幅広い密着による弾性緩衝体の離脱抑制作用と、装着溝の表面側装着溝及び弾性緩衝体の表面側嵌合部の途中に存在する幅変化部位による溝長手方向でのずれ抑制作用とにより、弾性緩衝体を外力に抗して所期の嵌合装着状態に良好に維持することができる。   According to the above configuration, the groove width of the mounting groove on the surface side of the mounting groove at the part where the collision frequency with other objects is high, and the width of the surface side fitting portion of the elastic buffer body fitted and mounted in close contact therewith are other. Since the width of the surface side mounting groove of the mounting groove and the surface side fitting portion of the elastic buffer body are configured to be the same width on the entire circumference, other than It is possible to enhance the buffering function at the part where the collision frequency with the object is high, and to suppress the detachment of the elastic buffer due to the wide contact between the mounting groove and the elastic buffer, and the surface side mounting groove and the elastic buffer of the mounting groove The elastic cushioning body can be well maintained in the intended fitted state against the external force by the effect of suppressing the shift in the longitudinal direction of the groove due to the width change part existing in the middle of the front side fitting part .

本発明による第３の特徴構成は、前記弾性緩衝体の表面側嵌合部の広幅表面側嵌合部分の表面には、当該広幅表面側嵌合部分に連続する細幅表面側嵌合部分の表面よりも外方に突出する緩衝突条が形成されている点にある。 According to a third characteristic configuration of the present invention, the surface of the wide-surface-side fitting portion of the surface-side fitting portion of the elastic buffer is provided with a narrow-surface-side fitting portion that is continuous with the wide-surface-side fitting portion. A buffering ridge that protrudes outward from the surface is formed.

上記構成によれば、前記弾性緩衝体の表面側嵌合部の広幅表面側嵌合部分の表面に突出形成された緩衝突条による緩衝厚みの増加により、他物との衝突頻度が高い部位での緩衝機能を効果的に高めることができる。   According to the above configuration, at the portion where the collision frequency with the other object is high due to the increase in the buffer thickness by the buffer ridge protruding from the surface of the wide surface side fitting portion of the surface side fitting portion of the elastic buffer. The buffer function can be effectively enhanced.

It is detachably fitted.

前記弾性緩衝体８は、基台２の外周面２ａの最大輪郭部位を乗り越え移動可能な状態にまで拡大（拡径）側に弾性変形操作可能で、前記基台２の装着溝７に弾性緩衝体８を嵌合装着した状態では、この弾性緩衝体８の表面側は基台２の外周面２ａよりも外方に突出し、且つ、弾性緩衝体８の嵌合部側は、当該弾性緩衝体８の弾性復元力によって装着溝７の内面７ａに密着しているから、他物との衝突時の衝撃力を緩和することができるとともに、この衝突時の外力に対して弾性緩衝体８を装着溝７に嵌合させた初期の装着状態に維持することができる。   The elastic buffer 8 can be elastically deformed to the side of expansion (expansion) to a state where it can move over the maximum contour portion of the outer peripheral surface 2 a of the base 2, and is elastically buffered in the mounting groove 7 of the base 2. In a state where the body 8 is fitted and mounted, the surface side of the elastic buffer 8 protrudes outward from the outer peripheral surface 2a of the base 2, and the fitting portion side of the elastic buffer 8 is the elastic buffer. 8 is in close contact with the inner surface 7a of the mounting groove 7 due to the elastic restoring force, so that the impact force at the time of collision with another object can be reduced and the elastic buffer 8 is mounted against the external force at the time of collision. The initial mounting state fitted in the groove 7 can be maintained.

前記基台２の装着溝７は、細幅の底面側装着溝７Ａとこれよりも少し広幅の表面側装着溝７Ｂとから構成されているとともに、前記弾性緩衝体８の嵌合部が、前記底面側装着溝７Ａに密着状態で嵌合装着される細幅の底面側嵌合部８Ａと、前記表面側装着溝７Ｂに密着状態で嵌合装着される広幅の表面側嵌合部８Ｂとから構成されている。   The mounting groove 7 of the base 2 is composed of a narrow bottom surface mounting groove 7A and a slightly wider surface side mounting groove 7B, and the fitting portion of the elastic buffer 8 is the From a narrow bottom surface side fitting portion 8A fitted and mounted to the bottom surface side mounting groove 7A in a close contact state, and a wide surface side fitting portion 8B fitted to and attached to the front surface side mounting groove 7B in a close contact state.
