Description

本発明は、多数の毛体を保持体に保持させるブラシ体に関するものであり、電動式等の回転ブラシに用いられるのに適したブラシ体に関するものである。   The present invention relates to a brush body that holds a large number of hair bodies on a holding body, and relates to a brush body that is suitable for use in a rotating brush such as an electric type.

従来、この種のブラシ体としては、多数の条体からなる束(本願発明の毛体に相当する)を緊締体(本願発明の結束帯)によって緊締し、前記緊締体の延設部と条体保持器(本願発明の保持体)の挿入孔に挿入した状態で、緊締体の延設部と条体保持器を固定したものが知られている(例えば、特許文献1参照)。このようなブラシ体は、多数の条体の束を緊締体で緊締した後、この緊締体の延設部を条体保持器の挿入孔に挿入し、固定用係合部で固定することで製造されるので、効率的に製造することができる。   Conventionally, as this kind of brush body, a bundle (corresponding to the hair body of the present invention) consisting of a large number of strips is fastened by a tightening body (binding band of the present invention), and the extension part and strip of the tightening body are tightened. There has been known a structure in which an extension portion of a tightening body and a strip cage are fixed in a state of being inserted into an insertion hole of a body cage (holding body of the present invention) (for example, see Patent Document 1). In such a brush body, a bundle of a large number of strips is tightened with a tightening body, and then an extended portion of the tightening body is inserted into an insertion hole of the strip body holder and fixed by a fixing engaging portion. Since it is manufactured, it can manufacture efficiently.

特開2013−39253号公報JP 2013-39253 A

このようなブラシ体は、条体の束が条体保持器に対し一箇所で固定される。そして、この構造は、手持ち型で且つ柄体が条体保持器に対して傾斜して設けられるようなものであれば、問題は表面化しない。しかしながら、上述の構造を回転ブラシに応用しようとすると、以下のような問題が生ずる。即ち、回転ブラシでは、条体保持体の中央に、回転軸に取り付けるための取付部を設ける必要があるため、挿入孔を条体保持器の中央に設けることができない。従って、挿入孔は、前記条体保持器の中心からずれた位置に設けざるを得ない。そして、条体の束を緊締体によって条体保持器の中央からずれた位置で固定したブラシ体を回転ブラシ本体に取り付け、回転させると、条体の束に加わる力で回転中心を基準として不均衡となり、最悪の場合、条体の束が条体保持器の椀形内面部から外れてしまう虞があった。   In such a brush body, a bundle of strips is fixed to the strip holder in one place. If this structure is a hand-held type and the handle is provided to be inclined with respect to the strip holder, the problem does not surface. However, when the above structure is applied to a rotating brush, the following problems occur. That is, in the rotating brush, since it is necessary to provide an attachment portion for attaching to the rotating shaft at the center of the strip holder, the insertion hole cannot be provided at the center of the strip holder. Therefore, the insertion hole must be provided at a position shifted from the center of the strip holder. Then, when a brush body, which is fixed at a position displaced from the center of the body cage by the tightening body, is attached to the rotating brush body and rotated, the force applied to the bundle of strips is inferior with respect to the center of rotation. In the worst case, the bundle of strips may come off the saddle-shaped inner surface of the strip cage.

本発明は以上の問題点を解決し、回転ブラシに用いたとしても毛体を保持体に対し安定して保持することができるブラシ体を提供することを目的とする。   An object of the present invention is to solve the above problems and to provide a brush body capable of stably holding a hair body against a holding body even when used for a rotating brush.

The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

図1〜図11は実施例1を示す。1はブラシ体である。このブラシ体1は、浴槽、浴室、或いは車両等の対象物の洗浄に用いるものである。なお、このブラシ体1は、合成樹脂製、金属製、或いはタイル製の浴槽又は浴室内面の洗浄に特に適する。   1 to 11 show a first embodiment. 1 is a brush body. The brush body 1 is used for cleaning an object such as a bathtub, a bathroom, or a vehicle. The brush body 1 is particularly suitable for cleaning a bathtub made of synthetic resin, metal, or tile, or the inner surface of a bathroom.

前記ブラシ体1は、多数の毛体2からなる束3と、この束3の中央部3Aを結束した毛束用結束帯4と、保持体5と、前記毛束用結束帯4により結束された束3を前記保持体5に保持するための保持体用結束帯6とを備える。また、前記ブラシ体1は、電動ブラシ本体7に取り付けられる。この電動ブラシ本体7には、前記ブラシ体1を回動駆動するための回動駆動手段8が設けられる。そして、これらブラシ体1と電動ブラシ本体7とにより、電動ブラシ9が構成される。   The brush body 1 is bundled by a bundle 3 composed of a large number of hair bodies 2, a bundling band 4 for bundling the central portion 3A of the bundle 3, a holding body 5, and the bundling band 4 for bristles. A holding body binding band 6 for holding the bundle 3 on the holding body 5. The brush body 1 is attached to the electric brush body 7. The electric brush body 7 is provided with a rotation driving means 8 for rotating the brush body 1. The brush body 1 and the electric brush body 7 constitute an electric brush 9.

前記毛体2は、ポリプロピレンフィルムを一方向に延伸した後、多数の細い繊維に割いて作られた、いわゆるスプリットヤーンと呼ばれるものである。   The hair body 2 is a so-called split yarn made by stretching a polypropylene film in one direction and then breaking it into a large number of thin fibers.

前記束3は、上述した多数のポリプロピレン製スプリットヤーンの毛体2からなるものである。そして、これらの毛体2からなる束3は、同方向を向くようにして全体として長方形の厚めのシート状に配列される。そして、この束3は、その中央部3Aにおいて熱熔着された後、熔着帯の両側が縫製される。なお、ここで言う中央部3Aとは、前記毛体2の長さ方向の中央部という意味である。このようにして、前記毛体2は、中央部3Aにおいて固定され、前記束3が構成される。更に、このように中央部3Aが固定された前記束3を複数回折り畳んだ後、この束3の中央部3Aが前記毛束用結束帯4の結束部11により緊締される。これにより、多数の前記毛体2は、中央部3Aの被緊締箇所よりも外側が広がった状態となる。   The bundle 3 is composed of the above-described many split split yarn hairs 2 made of polypropylene. And the bundle 3 which consists of these hair bodies 2 is arranged in a rectangular thick sheet shape as a whole so that it may face the same direction. And this bundle 3 is heat-welded in the center part 3A, Then, both sides of a welding belt are sewn. In addition, the center part 3A said here means the center part of the length direction of the said hair body 2. As shown in FIG. In this way, the hair body 2 is fixed at the central portion 3A, and the bundle 3 is formed. Further, after the bundle 3 having the central portion 3A fixed in this manner is folded a plurality of times, the central portion 3A of the bundle 3 is fastened by the binding portion 11 of the bundling band 4 for the hair bundle. Thereby, many said hair bodies 2 will be in the state which the outer side expanded rather than the to-be-tightened location of 3 A of center parts.

前記毛束用結束帯4は、長さ方向に沿ってセレーション12Aが設けられた可撓性の帯状部12と、この帯状部12を挿通する貫通孔(図示せず)を有すると共に前記セレーション12Aに対応する爪が設けられた頭部13とが、ポリアミド樹脂等の合成樹脂により一体成形されたものである。なお、この結束帯4の構造は、一般によく知られたもの(例えば、『インシュロック』(ヘラマンタイトン株式会社の登録商標)等がよく知られている)なので、詳細な説明は省略する。そして、前記帯状部12を前記頭部13の図示しない貫通孔に挿通することにより、これらの帯状部12と頭部13とが環状をなして前記結束部11が構成される。なお、前記帯状部12のうち、前記頭部13の孔を通過した部分が余部14となる。また、前記頭部13は、略直方体状をなす。   The bundling band 4 for hair bundles has a flexible belt-like portion 12 provided with serrations 12A along the length direction, and a through-hole (not shown) through which the belt-like portion 12 is inserted, and the serration 12A. And a head 13 provided with a claw corresponding to is integrally formed of a synthetic resin such as a polyamide resin. The structure of the tying band 4 is generally well-known (for example, “Insulok” (registered trademark of Heraman Tighton Co., Ltd.) and the like, and detailed description thereof is omitted. Then, by inserting the belt-like portion 12 into a through hole (not shown) of the head portion 13, the belt-like portion 12 and the head portion 13 form an annular shape to constitute the binding portion 11. In addition, the part which passed the hole of the said head 13 among the said strip | belt-shaped parts 12 becomes the surplus part 14. FIG. The head 13 has a substantially rectangular parallelepiped shape.

よって、前記帯状部12を、前記頭部13の図示しない貫通孔に通し、前記結束部11を締める向きに移動させることにより、この結束部11は、前記毛体2の束3を緊締する内周の長さを漸次縮小させて締め付けることができる。そして、前記結束部11により前記毛体2の束3を締め付けることで前記結束部11が縮小すると同時に、この結束部11を構成していた部分が前記余部14の一部になって余部14が延長される。   Therefore, by passing the belt-like portion 12 through a through hole (not shown) of the head 13 and moving the binding portion 11 in a tightening direction, the binding portion 11 is used to tighten the bundle 3 of the hair bodies 2. The circumference can be gradually reduced and tightened. When the bundling portion 11 is tightened by the bundling portion 11, the bundling portion 11 is reduced. At the same time, the portion constituting the bundling portion 11 becomes a part of the surplus portion 14. Extended.

Thus, the drive shaft 27 can be inserted into the engagement hole 28 when the linear pin portion 29 </ b> A comes out of the engagement hole 28. When the shaft side cutout groove 47A overlaps the cutout groove 30, the straight pin portion 29A is restored, and the straight pin portion 29A engages with the shaft side cutout groove 47A. As described above, the linear pin portion 29A engages with the shaft-side cutout groove 47A, so that the driven shaft 27 is coupled in a state of being prevented from coming off.

また、前記保持体5の基端側である下部の左右には、湾曲状板材からなる把持板48,48が下方に向って突設される。使用者は、この把持板48,48を把持することで、前記ブラシ体1を電動ブラシ本体7に対し容易に着脱することができる。また、前記ブラシ体1を電動ブラシ本体7に取り付けた状態で、前記駆動軸47と従動軸27との連結箇所の一部が、前記把持板48,48により覆われて隠される。これによって、例えば風呂を清掃する際に、風呂の栓を繋いでいるチェーン等が前記駆動軸47や従動軸27に絡むのを抑制することができる。   On the left and right sides of the lower part, which is the base end side of the holding body 5, grip plates 48, 48 made of a curved plate material are provided so as to project downward. The user can easily attach and detach the brush body 1 to and from the electric brush body 7 by gripping the grip plates 48 and 48. In addition, in a state where the brush body 1 is attached to the electric brush main body 7, a part of the connection portion between the drive shaft 47 and the driven shaft 27 is covered and hidden by the grip plates 48 and 48. Thereby, for example, when cleaning the bath, it is possible to prevent the chain connecting the bath plugs from being entangled with the drive shaft 47 and the driven shaft 27.

次に、前記保持体5への毛体2の取付保持方法の一例を説明する。前述した通り、前記束3は、多数のポリプロピレン製スプリットヤーンの毛体2からなる。このポリプロピレン製スプリットヤーンは、ポリプロピレンフィルムを一方向に延伸した後、多数の細い繊維に割くことで、予め生成される。そして、このようにして生成されたスプリットヤーンからなる毛体2を、同方向を向くように配列して、全体として長方形の厚めのシート状とする。このように配列された前記毛体2の長さ方向中央部を熱熔着した後、熔着帯の両側をミシン等で縫製する。このようにして、中央部3Aにおいて前記毛体2が固定された前記束3が構成される。更に、このように中央部3Aが固定された前記束3を、前記毛体2の配列方向に沿って複数回折り畳んで重ね合わせる(図8)。そして、前記束3の中央部3Aに前記毛束用結束帯4の帯状部12を巻き付けた後、前記帯状部12の端部を前記頭部13の図示しない貫通孔に挿通する(図9)。更に、前記結束部11により前記束3の中央部3Aを結束し、この後、前記余部14の不要部分を切断除去する(図10)。   Next, an example of a method for attaching and holding the hair body 2 to the holding body 5 will be described. As described above, the bundle 3 is composed of a large number of polypropylene split yarn hair bodies 2. This polypropylene split yarn is produced in advance by stretching a polypropylene film in one direction and then breaking it into a large number of thin fibers. Then, the hair bodies 2 made of the split yarns generated in this way are arranged so as to face in the same direction to form a thick rectangular sheet as a whole. After heat welding the longitudinal direction center part of the said hair body 2 arranged in this way, both sides of the welding belt are sewed with a sewing machine or the like. In this way, the bundle 3 in which the hair body 2 is fixed in the central portion 3A is configured. Further, the bundle 3 in which the central portion 3A is fixed in this way is folded and overlapped along the arrangement direction of the hair bodies 2 (FIG. 8). And after winding the strip | belt-shaped part 12 of the said binding band 4 for hair bundles around the center part 3A of the said bundle 3, the edge part of the said strip | belt-shaped part 12 is penetrated to the through-hole which the said head 13 does not illustrate (FIG. 9). . Furthermore, the central portion 3A of the bundle 3 is bound by the binding portion 11, and thereafter, unnecessary portions of the extra portion 14 are cut and removed (FIG. 10).

前記保持体5側においては、前記孔34に、前記保持体5の外側から前記保持体用結束帯6の帯状部16を挿入する。そして、この帯状部16を、前記束3の中央部3A、好ましくは前記毛束用結束帯4の帯状部12の上に重ねて巻き付けた後、前記帯状部16の先端部を、前記保持体5の内側から前記孔35に挿入する。なお、前記帯状部16は、必ずしも前記帯状部12と重なるように巻き付けなくてもよい。例えば、前記帯状部16を、前記帯状部12の近傍で前記束3の中央部3Aに巻き付けてもよい。そして、前記帯状部16の先端を、前記頭部19の図示しない貫通孔に挿通し、前記帯状部16のセレーションと前記頭部19の爪を係合させる。更に、図1等に示すように、頭部17,19をそれぞれ凹部36,37に収納した状態で、前記帯状部16と頭部19とで、前記束3の中央部3Aを緊締することで、前記束3を前記保持体5に固定する。その後、前記余部18を切断する。この場合、前記帯状部16の切断端16Tが凹部37内に位置するように切断する。そして、図1に示すように、前記凹部36の深さ寸法は、前記頭部17の高さ寸法より大きく、また、前記凹部37の深さ寸法は、前記頭部19の高さ寸法より小さい。従って、側面視において、前記頭部17,19及び切断端16Tが前記筒部から露出することがない。なお、前述した通り、前記頭部17と頭部19は同一であり、図1においては向きが異なるだけである。図1の場合、前記頭部17の高さ寸法は、前記頭部19の幅寸法に等しい。一方、前記頭部17の幅寸法は、前記頭部19の高さ寸法に等しい。そして、前記毛体2の先端を切断して毛長を整え、整形する。更に、前述したように、前記スナップピン29を前記従動軸27の切欠溝30及び係合溝31に装着することで、前記ブラシ体1が完成する。   On the side of the holding body 5, the belt-like portion 16 of the holding body binding band 6 is inserted into the hole 34 from the outside of the holding body 5. And after winding this strip | belt-shaped part 16 on the strip | belt-shaped part 12 of the center part 3A of the said bundle | bundle 3, Preferably the said binding band 4 for hair bundles, the front-end | tip part of the said strip | belt-shaped part 16 is made into the said holding body 5 is inserted into the hole 35 from the inside. Note that the belt-like portion 16 does not necessarily have to be wound so as to overlap the belt-like portion 12. For example, the strip 16 may be wound around the central portion 3A of the bundle 3 in the vicinity of the strip 12. And the front-end | tip of the said strip | belt-shaped part 16 is inserted in the through-hole which the said head 19 does not illustrate, and the serration of the said strip | belt-shaped part 16 and the nail | claw of the said head 19 are engaged. Further, as shown in FIG. 1 and the like, the central portion 3A of the bundle 3 is fastened by the belt-like portion 16 and the head portion 19 with the head portions 17 and 19 being housed in the recess portions 36 and 37, respectively. The bundle 3 is fixed to the holding body 5. Thereafter, the surplus portion 18 is cut. In this case, cutting is performed so that the cut end 16 </ b> T of the belt-like portion 16 is positioned in the recess 37. As shown in FIG. 1, the depth of the recess 36 is larger than the height of the head 17, and the depth of the recess 37 is smaller than the height of the head 19. . Accordingly, the heads 17 and 19 and the cut end 16T are not exposed from the cylindrical part in a side view. As described above, the head 17 and the head 19 are the same, and only the directions are different in FIG. In the case of FIG. 1, the height of the head 17 is equal to the width of the head 19. On the other hand, the width of the head 17 is equal to the height of the head 19. And the front-end | tip of the said hair body 2 is cut | disconnected, hair length is adjusted, and it shape | molds. Further, as described above, the brush body 1 is completed by mounting the snap pin 29 in the notch groove 30 and the engagement groove 31 of the driven shaft 27.

このようにして前記毛体2の束3を保持した前記保持体5を、前述の手順で前記電動ブラシ本体7に取り付ける。この後、前記操作部42Sを操作して前記電動機45を駆動することで、前記ブラシ体1が回転する。この際、図1に示すように、前記保持体用結束帯6により前記毛体2の束3の中央部3Aが、前記従動軸27の延長線上で、且つ、前記保持体用結束帯6の帯状部16の両端が前記頭部17,19により均等に緊張されると共に、前記帯状部16を通す孔34,35が前記従動軸27に対して略対称な位置にあるため、前記束3を確実に保持することができると共に、前記ブラシ体1が回転しても、前記毛体2の束3を前記保持体5に対し安定して保持させることができる。   In this way, the holding body 5 holding the bundle 3 of the hair bodies 2 is attached to the electric brush body 7 in the above-described procedure. Thereafter, the brush body 1 is rotated by operating the operating portion 42S to drive the electric motor 45. At this time, as shown in FIG. 1, the central portion 3 </ b> A of the bundle 3 of the bristles 2 is formed on the extension line of the driven shaft 27 by the holding body binding band 6 and the holding body binding band 6. Since both ends of the belt-like portion 16 are evenly tensioned by the head portions 17 and 19 and the holes 34 and 35 through which the belt-like portion 16 is passed are at positions substantially symmetrical with respect to the driven shaft 27, the bundle 3 is While being able to hold | maintain reliably, even if the said brush body 1 rotates, the bundle | flux 3 of the said hair body 2 can be stably hold | maintained with respect to the said holding body 5.
