Description

本発明は、塵埃等の捕集物を捕集する捕集ロールを回転可能に取り付けて清掃に用いられる清掃具に関する。   The present invention relates to a cleaning tool that is used for cleaning by rotatably attaching a collecting roll that collects collected matter such as dust.

この種の清掃具としては、棒状の柄の先端部からその両側へ、粘着ロール等の円筒状の捕集ロールが外挿されるロール支持軸が柄に垂直に突出された構成のものがある（以下、第１の従来清掃具、とも言う。例えば特許文献１）。
また、この種の清掃具としては、柄の先端部に、捕集ロールを回転自在に支持するロール支持部材を、柄に対して揺動自在に支持する構成のものもある（以下、第２の従来清掃具、とも言う。例えば特許文献２）。ロール支持部材は、柄の先端部に支持される中央取付部からその両側に、捕集ロールが外挿されるロール支持軸が突出する構成である。
第１、第２の従来清掃具は、ロール支持軸に外挿して回転自在に支持した捕集ロールを床面等の被清掃面に転動させて、清掃に用いる。 As this type of cleaning tool, there is a configuration in which a roll support shaft from which a cylindrical collection roll such as an adhesive roll is inserted is projected perpendicularly to the handle from the tip of the rod-shaped handle to both sides thereof ( Hereinafter, it is also referred to as a first conventional cleaning tool, for example, Patent Document 1).
In addition, as this type of cleaning tool, there is a configuration in which a roll support member that rotatably supports a collection roll is supported at a tip end portion of a handle so as to be swingable with respect to the handle (hereinafter referred to as a second type). Also known as a conventional cleaning tool, for example, Patent Document 2). The roll support member has a configuration in which a roll support shaft on which a collection roll is extrapolated projects from both sides of the center mounting portion supported by the tip end portion of the handle.

第１の従来清掃具は柄に対して固定のロール支持軸に捕集ロールを軸支する。第２の従来清掃具は、一対のロール支持軸が中央取付部に固定されているロール支持部材を用いる。このため、第１、第２の従来清掃具は、例えば湾曲した被清掃面の清掃に用いる場合、一対の捕集ロールのそれぞれの側周面を被清掃面に同時接触させながら被清掃面の湾曲軸線方向に転動移動させることが難しく、清掃に手間が掛かることがあった。また、家屋の柱、梁や、ソファーなどの家具等における開き角を以て互いに隣接する２面を清掃する場合や、着衣のままで腕や脚などの衣服を清掃する場合には、柄先端部両側の捕集ロールの片方ずつしか清掃に活用できないケースが多く、被清掃面に捕集ロールを転動させる回数が増大して清掃に手間が掛かることがあった。   The first conventional cleaning tool supports the collection roll on a roll support shaft fixed to the handle. The second conventional cleaning tool uses a roll support member in which a pair of roll support shafts are fixed to the central mounting portion. For this reason, when the first and second conventional cleaning tools are used for cleaning, for example, a curved surface to be cleaned, the side circumferential surfaces of the pair of collecting rolls are simultaneously brought into contact with the surface to be cleaned while being cleaned. It is difficult to roll and move in the direction of the curved axis, and it may take time and effort for cleaning. Also, when cleaning two surfaces adjacent to each other with an opening angle in furniture such as a house pillar, beam, and sofa, or when cleaning clothes such as arms and legs while wearing clothes, In many cases, only one of the collection rolls can be used for cleaning, and the number of times the collection roll rolls on the surface to be cleaned is increased, which requires time and effort for cleaning.

図６の場合、清掃具１０は、湾曲した被清掃面６１（図６中、符号６１ｂを付記する）や、開き角を以て互いに隣接する複数の被清掃面の清掃を効率良く行える。 FIG. 6 shows a case where the opening angle θ of the pair of roll support shafts 42 is between the initial angle and 180 degrees.
In the case of FIG. 6, the cleaning tool 10 can efficiently clean a curved surface to be cleaned 61 (indicated by reference numeral 61b in FIG. 6) and a plurality of surfaces to be cleaned adjacent to each other with an opening angle.

図６の被清掃面６１ｂは、具体的には衣服の袖の側周面（以下、袖側周面、とも言う）である。被清掃面６１ｂは、その湾曲軸線方向において、湾曲半径が一定で無い。
清掃具１０は、例えば、衣服の着用者が衣服の袖に腕を通したままの状態で一対のロール支持軸４２を押し付け、ロール支持軸４２を袖軸線方向に沿って転動させることで、一対のロール支持軸４２の開き角θが被清掃面６１ｂ（袖側周面）の湾曲半径に応じて初期角度と１８０度との間の範囲で変動する。その結果、清掃具１０は、各ロール支持軸４２にそれぞれ外挿した捕集ロール５０を、被清掃面６１ｂ（袖側周面）にその湾曲半径に応じて追従させて被清掃面６１ｂとの接触状態を保つことができ、被清掃面６１を効率良く清掃できる。 The surface to be cleaned 61b in FIG. 6 is specifically a side peripheral surface of a sleeve of clothes (hereinafter also referred to as a sleeve side peripheral surface). The surface to be cleaned 61b does not have a constant curvature radius in the direction of the curved axis.
For example, the cleaning tool 10 presses the pair of roll support shafts 42 while the wearer of the garment keeps his arm on the sleeve of the garment, and rolls the roll support shaft 42 along the sleeve axis direction. The opening angle θ of the pair of roll support shafts 42 varies in a range between the initial angle and 180 degrees according to the radius of curvature of the surface to be cleaned 61b (sleeve side peripheral surface). As a result, the cleaning tool 10 causes the collection roll 50, which is extrapolated to each roll support shaft 42, to follow the surface to be cleaned 61b (sleeve side peripheral surface) according to the radius of curvature thereof and the surface to be cleaned 61b. The contact state can be maintained, and the surface to be cleaned 61 can be efficiently cleaned.

なお、湾曲した被清掃面６１ｂは、袖側周面に限定されず、例えばズボン股下の使用者が脚部を通す筒状部（脚挿通筒部）の側周面、ソファ等の家具に存在する湾曲した被清掃面等も採用可能である。
また、清掃具１０は、家屋の柱、梁や、ソファーなどの家具等における開き角を以て互いに隣接する２面の清掃も効率良く行える。 The curved surface to be cleaned 61b is not limited to the sleeve side peripheral surface. For example, the curved peripheral surface 61b is present on the side peripheral surface of a tubular portion (leg insertion tube portion) through which a leg pants user passes and furniture such as a sofa. A curved surface to be cleaned or the like can also be employed.
The cleaning tool 10 can also efficiently clean two surfaces adjacent to each other with an opening angle in furniture such as a pillar or beam of a house or a sofa.

清掃具１０は、湾曲した被清掃面６１ｂや、開き角を以て互いに隣接する複数の被清掃面に対して、一対のロール支持軸４２にそれぞれ外挿した捕集ロール５０の両方を接触させつつ転動させることができる。その結果、清掃具１０は、被清掃面に対する捕集ロール５０の転動回数を削減でき、被清掃面の清掃を効率良く行える。   The cleaning tool 10 rolls while bringing both the collecting rolls 50 extrapolated to the pair of roll support shafts 42 into contact with the curved surface to be cleaned 61b and a plurality of surfaces to be cleaned adjacent to each other with an opening angle. Can be moved. As a result, the cleaning tool 10 can reduce the number of rolling of the collection roll 50 with respect to the surface to be cleaned, and can efficiently clean the surface to be cleaned.

図５、図６に示すように、被清掃面６１への押圧によって開き角θを初期角度よりも大きく拡げた一対のロール支持軸４２は、付勢部材１１によって、開き角を縮小する方向へ弾性付勢されている。被清掃面６１への押圧によって開き角θを初期角度よりも大きく拡げた一対のロール支持軸４２は、例えば柄部２０の操作によって被清掃面６１から離隔させ清掃具１０の構成部材以外との接触が存在しない状態とするだけで、付勢部材１１の弾性付勢力によって開き角が縮小して初期状態に復帰する。   As shown in FIGS. 5 and 6, the pair of roll support shafts 42 whose opening angle θ is larger than the initial angle by pressing the surface to be cleaned 61 are reduced by the biasing member 11 in the direction of reducing the opening angle. It is elastically biased. The pair of roll support shafts 42 whose opening angle θ is larger than the initial angle by pressing on the surface to be cleaned 61 are separated from the surface to be cleaned 61 by, for example, operation of the handle portion 20, and other than the constituent members of the cleaning tool 10. By simply setting the state in which no contact exists, the opening angle is reduced by the elastic biasing force of the biasing member 11 and the initial state is restored.

一対のロール支持軸４２の開き角θの初期角度が１８０度未満である清掃具１０は、一対のロール支持軸４２が初期状態であるときに開き角θが１８０度であるときに比べて、一対のロール支持軸４２の柄部２０に垂直の方向の寸法を小さく抑えることができる。
このため、一対のロール支持軸４２の開き角θの初期角度が１８０度未満である清掃具１０は、例えば各ロール支持軸４２に外挿した捕集ロール５０を収納場所の床面（以下、収納スペース床面、とも言う）に載置して収納するときに、一対のロール支持軸の開き角が１８０度で固定の従来構成の清掃具に比べて、一対のロール支持軸４２をそれぞれに外挿した捕集ロール５０とともに収納するに要する収納スペース床面面積の縮小が可能である。清掃具１０は、一対のロール支持軸４２を初期状態とすることで、一対のロール支持軸４２のそれぞれに外挿した捕集ロール５０を含む収納スペースの縮小に有利である。 The cleaning tool 10 in which the opening angle θ of the pair of roll support shafts 42 is less than 180 degrees is compared with the cleaning tool 10 when the opening angle θ is 180 degrees when the pair of roll support shafts 42 is in the initial state. The dimension in the direction perpendicular to the handle 20 of the pair of roll support shafts 42 can be kept small.
For this reason, the cleaning tool 10 in which the initial angle of the opening angle θ of the pair of roll support shafts 42 is less than 180 degrees includes, for example, the collection rolls 50 extrapolated to the respective roll support shafts 42 (hereinafter referred to as the floor surface of the storage location). When the storage space is also placed and stored on the floor of the storage space), the pair of roll support shafts 42 are respectively provided as compared with a conventional cleaning tool in which the opening angle of the pair of roll support shafts is fixed at 180 degrees. It is possible to reduce the storage space floor area required for storage together with the extrapolated collection roll 50. The cleaning tool 10 is advantageous in reducing the storage space including the collection roll 50 extrapolated to each of the pair of roll support shafts 42 by setting the pair of roll support shafts 42 in the initial state.

図８は、清掃具１０の一対の軸支持部材４１の開き角下限当接部４１ｄ間に挟み込まれる介挿部材１２の一例を示す。
図８の介挿部材１２は、図１〜図７を参照して説明した清掃具１０の一対の軸支持部材４１の片方の開き角下限当接部４１ｄに回転軸１２ａを介して枢着された板状片である。 FIG. 8 shows an example of the insertion member 12 sandwiched between the opening angle lower limit contact portions 41 d of the pair of shaft support members 41 of the cleaning tool 10.
The insertion member 12 of FIG. 8 is pivotally attached to one opening angle lower limit abutting portion 41d of the pair of shaft support members 41 of the cleaning tool 10 described with reference to FIGS. 1 to 7 via a rotation shaft 12a. It is a plate-shaped piece.

図８の一対の軸支持部材４１の開き角下限当接部４１ｄには互いに当接される当接面４１ｆが形成されている。
図８の介挿部材１２は、回転軸１２ａを中心とする手動回転によって、回転軸１２ａを介して取り付けられた開き角下限当接部４１ｄの当接面４１ｆに重ね合わされた状態と、当接面４１ｆから垂直に突出する状態とを切り換えることができる。図８の清掃具は、介挿部材１２を開き角下限当接部４１ｄの当接面４１ｆから垂直に突出する状態とすることで、介挿部材１２を開き角下限当接部４１ｄの当接面４１ｆに重ね合わされた状態（格納状態）とした場合に比べて、一対のロール支持軸４２の開き角θの初期角度を大きく設定できる。介挿部材１２は、当接面４１ｆに重ね合わされた状態と、当接面４１ｆから垂直に突出する状態とを切り換えることで、一対の軸支持部材４１の初期状態における開き角下限当接部４１ｄ間隔（間隔方向の寸法）を変更可能である。 The pair of shaft support members 41 in FIG. 8 have contact surface 41f that is in contact with each other at the opening angle lower limit contact portion 41d.
The insertion member 12 of FIG. 8 is in contact with the contact surface 41f of the opening angle lower limit contact portion 41d attached via the rotation shaft 12a by manual rotation about the rotation shaft 12a. The state of projecting vertically from the surface 41f can be switched. The cleaning tool of FIG. 8 makes the insertion member 12 project vertically from the abutment surface 41f of the opening angle lower limit abutting portion 41d, so that the insertion member 12 contacts the opening angle lower limit abutting portion 41d. The initial angle of the opening angle θ of the pair of roll support shafts 42 can be set larger than in the case where the surface is overlapped with the surface 41f (stored state). The insertion member 12 switches between a state of being superimposed on the contact surface 41f and a state of projecting vertically from the contact surface 41f, whereby the opening angle lower limit contact portion 41d in the initial state of the pair of shaft support members 41 is switched. The interval (dimension in the interval direction) can be changed.

なお、介挿部材１２は、図８に例示した板状片に限定されない。
介挿部材は、例えば、一対の軸支持部材４１の開き角下限当接部４１ｄの一方または両方に螺着されて、回転操作によって一対の開き角下限当接部４１ｄ間への突出寸法を変更可能な調整ねじ自体や、この調整ねじ先端に一対の開き角下限当接部４１ｄ間に挟み込まれる部材が取り付けられた構成、等であっても良い。 The insertion member 12 is not limited to the plate-like piece illustrated in FIG.
For example, the insertion member is screwed into one or both of the opening angle lower limit contact portions 41d of the pair of shaft support members 41, and changes the projecting dimension between the pair of opening angle lower limit contact portions 41d by a rotation operation. The possible adjustment screw itself, a configuration in which a member sandwiched between the pair of opening angle lower limit contact portions 41d is attached to the tip of the adjustment screw, or the like may be used.
