Description

本発明は、手作業での洗車に適した洗車具に関する。 The present invention relates to a car wash tool suitable for manual car washing.

特許文献１は、比較的小型の自動車、例えば普通自動車を個人が洗車する場合に好適な洗車具として、底面に供給ノズルを設けた洗剤タンクと、前記洗剤タンクの底面を上面として錐台状に広がる弾性カバーと、前記弾性カバーの下周縁に装着した毛皮洗浄体と、そして弾性カバー及び毛皮洗浄体に挟まれて前記弾性カバー内に保持される泡立て体とから構成される洗浄ヘッドを備えた洗車具を開示する（特許文献１［請求項１］）。 Patent Document 1 discloses a detergent tank having a supply nozzle on the bottom surface as a car wash tool suitable for a person washing a relatively small automobile, for example, an ordinary automobile, and a frustum shape with the bottom surface of the detergent tank as an upper surface. A cleaning head comprising: an elastic cover that spreads; a fur cleaning body attached to a lower peripheral edge of the elastic cover; and a foamed body sandwiched between the elastic cover and the fur cleaning body and held in the elastic cover. A car wash tool is disclosed (Patent Document 1 [Claim 1]).

特許文献１が開示する洗車具は、洗剤タンクから弾性カバー内へ液状洗剤を供給し、毛皮洗浄体又は泡立てスポンジに水を含ませて、前記弾性カバーの変形によって圧縮及び復元を繰り返すことにより、泡立てスポンジが液状洗剤を泡立てる。このとき、弾性カバーの下周縁に毛皮洗浄体を装着しているので、この毛皮洗浄体に液状洗剤及び泡が染み込み又は絡ませて、洗浄ヘッドが泡を抱える格好にできる（特許文献１［0008］）。 The car wash tool disclosed in Patent Document 1 supplies liquid detergent from the detergent tank into the elastic cover, includes water in the fur washing body or foamed sponge, and repeats compression and restoration by deformation of the elastic cover, A lathering sponge lathers liquid detergent. At this time, since the fur cleaning body is attached to the lower peripheral edge of the elastic cover, the cleaning liquid is soaked or entangled in the fur cleaning body so that the cleaning head can hold the foam (Patent Document 1 [0008]). ).

洗浄タンクは、上下又は左右に揺動する自在継ぎ手を介して柄を接続している（特許文献１［0009］）。弾性カバーは、空気孔を開口して、毛皮洗浄体が車体に密着することによる弾性カバー内の負圧を防止し、弾性カバー内へ空気を取り込んで、圧縮及び復元するスポンジによる泡立てを促進させる（特許文献１［0010］）。また、下周縁から母線方向に設けた多数のスリットで区画される多数の弾性片により泡立てスポンジを押さえ込み、圧縮及び復元の変動量を大きくしている（特許文献１［0011］）。 The cleaning tank is connected to a handle via a universal joint that swings up and down or left and right (Patent Document 1 [0009]). The elastic cover opens air holes to prevent negative pressure in the elastic cover due to the fur-cleaning body coming into close contact with the vehicle body, and takes air into the elastic cover to promote foaming with a sponge that compresses and restores (Patent Document 1 [0010]). Further, the foaming sponge is pressed down by a large number of elastic pieces partitioned by a large number of slits provided in the generatrix direction from the lower peripheral edge to increase the amount of fluctuation in compression and restoration (Patent Document 1 [0011]).

毛皮洗浄体は、羊の毛皮（ムートン）を例示している（特許文献１［0012］）。泡立てスポンジは、弾性カバーに倣った錐台側面を有し、かつ平面視形状が毛皮洗浄体と相似な円環状である（特許文献１［0012］）。特許文献１が開示する洗車具は、液状洗剤を含み、水を吸った泡立てスポンジを大きく圧縮及び復元させることで、非常に泡立ちがよく、車体に密着しやすい毛皮洗浄体と相俟って、優れた洗浄作用を発揮する効果をもたらすとしている（特許文献１［0013］）。 The fur cleaning body is exemplified by sheep fur (mouton) (Patent Document 1 [0012]). The foamed sponge has a frustum side surface that follows the elastic cover, and has an annular shape similar to that of the fur washing body in a plan view (Patent Document 1 [0012]). The car wash tool disclosed in Patent Document 1 contains a liquid detergent, and by compressing and restoring a foamed sponge that has absorbed water, it is very foamy and combined with a fur washing body that is easy to adhere to the vehicle body, It is said that the effect of exhibiting an excellent cleaning action is brought about (Patent Document 1 [0013]).

特許文献１が開示する洗車具は、泡立てスポンジの圧縮及び復元による液状洗剤の泡立ちが顕著で、個人が用いる洗車具として優れていたが、必要十分の泡立ちを確保するためにはある程度容積を占める泡立ちスポンジが必要になるところ、前記泡立ちスポンジが水を吸って過剰に重くなることが分かった。とりわけ、洗浄タンクに柄を接続した構成の場合、柄の先端に構成される洗浄ヘッドが重くなると、とたんに洗浄ヘッドを左右又は上下に動かす際のモーメントが大きくなり、操作性が悪くなる問題をもたらす。 The car wash tool disclosed in Patent Literature 1 is remarkable as a car wash tool used by an individual with remarkable foaming of a liquid detergent due to compression and restoration of a foaming sponge. However, the car wash tool occupies a certain amount of volume to ensure necessary and sufficient foaming. When a foaming sponge is required, it has been found that the foaming sponge absorbs water and becomes excessively heavy. In particular, in the case of a configuration in which a handle is connected to the cleaning tank, if the cleaning head configured at the tip of the handle becomes heavier, the moment when the cleaning head is moved left and right or up and down is increased, resulting in poor operability. Bring.

また、液状洗剤と空気とを混ぜて泡立てる部材＝泡立て体としての泡立てスポンジは、弾性カバー内に占める容積の割に、それほど多くの泡を生成させるものでもないことがわかった。確かに、以前の同種洗車具に比べ、特許文献１が開示する洗車具の泡立ちは優れているが、泡立てスポンジの泡を生成する部分は主に表面のみであり、全体をうまく利用していない問題があった。そこで、基本構成は特許文献１が開示する洗浄ヘッドを踏襲しながら、より効率よく泡を生成する泡立て体を開発するため、検討した。 Further, it was found that a foaming sponge as a foaming member = a foaming material by mixing a liquid detergent and air does not generate much foam for the volume occupied in the elastic cover. Certainly, the foaming of the car wash disclosed in Patent Document 1 is superior to the previous similar car wash, but the part of the foamed sponge that produces foam is mainly the surface, and the whole is not used well. There was a problem. Therefore, the basic configuration was studied in order to develop a foaming body that generates bubbles more efficiently while following the cleaning head disclosed in Patent Document 1.

検討の結果開発したものが、供給ノズルを設けた洗剤タンクと、前記洗剤タンクの底面を上面として錐台状に広がる弾性カバーと、前記弾性カバーの下周縁に装着した毛皮洗浄体と、そして弾性カバー及び毛皮洗浄体に挟まれて前記弾性カバー内に保持される泡立て体とから構成される洗浄ヘッドを備えた洗車具において、泡立て体は、洗剤タンクの供給ノズルに始端が接続される供給パイプと、前記供給パイプの終端が接続され、複数の供給孔を開口した閉環状パイプと、前記閉環状パイプに外嵌した環状網体とから構成される洗車具である。弾性カバーは、後述するように、毛皮洗浄体を取付けるための取付カバーが装着される場合がある。この場合、弾性カバー及び毛皮洗浄体に挟まれる泡立て体は、取付カバーの内面と毛皮洗浄体の上面とに環状網体を摺接させる。 What has been developed as a result of the study is a detergent tank provided with a supply nozzle, an elastic cover that spreads in a frustum shape with the bottom surface of the detergent tank as an upper surface, a fur washing body attached to the lower periphery of the elastic cover, and elasticity In a car wash including a washing head composed of a foaming body held between the cover and the fur washing body and held in the elastic cover, the foaming body is a supply pipe whose start is connected to a supply nozzle of a detergent tank And a closed annular pipe connected to the end of the supply pipe and having a plurality of supply holes, and an annular mesh body externally fitted to the closed annular pipe. As will be described later, the elastic cover may be provided with a mounting cover for mounting the fur washing body. In this case, the foamed body sandwiched between the elastic cover and the fur cleaning body causes the annular mesh body to slidably contact the inner surface of the mounting cover and the upper surface of the fur cleaning body.

泡立て体は、供給パイプが接続された閉環状パイプを環状網体で包み込んだ外観を備える。供給パイプは、洗剤タンクと閉環状パイプとを結ぶことができればよいため、少なくとも可撓性を備えていることが望まれる。閉環状パイプは、弾性カバーの変形に伴う弾性カバー内の圧力変動を利用して供給孔から液状洗剤を放出する。特に弾性を備えた閉環状パイプは、環状網体を環状に保持する保形性を有するほか、自身が物理的な圧縮及び復元を繰り返して供給孔から液状洗剤を放出することもできる。閉環状パイプに設けられる供給孔は、半径方向内向きに設けるとよく、閉環状パイプの周方向等間隔で２個〜６個設けるとよい。これらに対し、環状網体は、網目の変形により泡を生成するため、弾性又は可撓性を備えていることが望まれる。 The foamed body has an appearance in which a closed annular pipe connected to a supply pipe is wrapped with an annular mesh body. Since the supply pipe only needs to be able to connect the detergent tank and the closed annular pipe, it is desirable that the supply pipe has at least flexibility. The closed annular pipe discharges the liquid detergent from the supply hole by utilizing the pressure fluctuation in the elastic cover accompanying the deformation of the elastic cover. In particular, the closed annular pipe having elasticity has a shape retaining property that holds the annular net in a ring shape, and can also discharge liquid detergent from the supply hole by repeating physical compression and restoration. The supply holes provided in the closed annular pipe may be provided inward in the radial direction, and may be provided in two to six at equal intervals in the circumferential direction of the closed annular pipe. On the other hand, in order to produce | generate a bubble by the deformation | transformation of a mesh, the cyclic | annular network body is desired to be provided with elasticity or flexibility.

本発明の洗車具は、特許文献１が開示する洗車具の泡立てスポンジに代えて、洗剤タンクの供給ノズルに始端が接続される供給パイプと、前記供給パイプの終端が接続され、複数の供給孔を開口した閉環状パイプと、前記閉環状パイプに外嵌した環状網体とから構成される泡立て体を用いる。液状洗剤は、洗剤タンクから供給パイプを通じて閉環状パイプに供給され、弾性カバーの変形に伴う弾性カバー内の圧力変動や弾性を備えた閉環状パイプの圧縮及び復元の働きを利用して前記閉環状パイプの供給孔から環状網体内に放出され、前記環状網体内で水と撹拌される。泡立て体は、水と撹拌された液状洗剤が網目に膜を張り、環状網体の内外に流入又は流出する空気が前記膜を膨らませて泡を生成する。 In the car wash tool of the present invention, instead of the foaming sponge of the car wash tool disclosed in Patent Document 1, a supply pipe whose start end is connected to a supply nozzle of a detergent tank, and a terminal end of the supply pipe are connected, and a plurality of supply holes A foamed body composed of a closed annular pipe having an opening and an annular mesh body externally fitted to the closed annular pipe is used. The liquid detergent is supplied from the detergent tank to the closed annular pipe through the supply pipe, and the closed annular pipe is utilized by the pressure fluctuation in the elastic cover accompanying the deformation of the elastic cover and the compression and restoration of the closed annular pipe having elasticity. It is discharged into the annular mesh body from the supply hole of the pipe, and is stirred with water in the annular mesh body. In the foaming body, water and a stirred liquid detergent form a film on the mesh, and air flowing into or out of the annular mesh expands the film to generate bubbles.

泡立てスポンジに代わる泡立て体を除き、本発明の洗車具の洗浄ヘッドは、特許文献１が開示する洗車具同様に構成できる。例えば洗剤タンクは、上下又は左右に揺動する自在継ぎ手を介して柄を接続するとよい。また、弾性カバーは、弾性を備えた樹脂板又は金属板を円錐状にまるめて形成するとよい。そして、毛皮洗浄体は、羊の毛皮（ムートン）を例示できる。後述するように、毛皮洗浄体は、弾性カバーの下周縁に直接取り付けるのではなく、弾性カバーに装着する取付カバーに取り付けるとよい。このとき、取付カバーの下周縁に環状の帯布を設けておくと、弾性カバー内に泡立て体を収納する空間を形成できる。帯布の内周面に沿って環状の弾性リングを介装すると、前記帯布により形成される空間の保形性が向上する。 The washing head of the car wash tool of the present invention can be configured in the same manner as the car wash tool disclosed in Patent Document 1 except for a foaming body that replaces the foaming sponge. For example, the detergent tank may be connected to a handle via a universal joint that swings up and down or left and right. The elastic cover may be formed by concentrating a resin plate or a metal plate having elasticity in a conical shape. And a fur washing body can illustrate the fur (mouton) of a sheep. As will be described later, the fur-cleaning body is not attached directly to the lower peripheral edge of the elastic cover, but is preferably attached to an attachment cover attached to the elastic cover. At this time, if an annular band cloth is provided on the lower peripheral edge of the mounting cover, a space for storing the foamed body can be formed in the elastic cover. When an annular elastic ring is interposed along the inner peripheral surface of the band cloth, the shape retention of the space formed by the band cloth is improved.

泡立て体を構成する環状網体は、弾性カバーの変形に応じて変形する可撓性又は弾性を備えていれば、素材や網目の大きさを問わないし、環状網体を複数重ねた多重構造でもよい。しかし、弾性カバー及び毛皮洗浄体に挟まれる狭い空間に収納でき、水及び空気を流入させて液状洗剤と十分に混ざり合せるため、泡立て体は、環状網体が内環状網体と外環状網体との二重構造が好適である。二重構造の環状網体は、内環状網体及び外環状網体の網目を交差させて大きさの変化する網目を形成し、前記網目に張った膜自体を変形させて泡の生成を促す。二重構造の環状網体は、内環状網体及び外環状網体の網目を交差させて形成される網目の並ぶ面が一層であり、前記網目に張った膜に内外から空気が流入し、膨らませやすい。 As long as the annular mesh body constituting the foamed body has flexibility or elasticity that deforms according to the deformation of the elastic cover, it does not matter the size of the material or mesh, and even a multiple structure in which a plurality of annular mesh bodies are stacked. Good. However, it can be stored in a narrow space between the elastic cover and the fur-cleaning body, and in order to allow water and air to flow in and sufficiently mix with the liquid detergent, the foamed body is composed of an inner ring network and an outer ring network. A double structure is preferred. The double-structured ring network crosses the mesh of the inner ring network and the outer ring network to form a mesh of varying size, and deforms the membrane itself to promote the generation of bubbles. . The double-structured ring network has a single layered surface formed by crossing the meshes of the inner and outer ring networks, and air flows from the inside to the outside of the membrane stretched over the mesh, Easy to inflate.

より好ましい泡立て体は、環状網体が相対的に網目の小さい内環状網体と相対的に網目の大きい外環状網体との二重構造である。例えば内環状網体の網目が相対的に小さく、逆に外環状網体の網目が相対的に大きい場合、両者の網目が交差して形成される網目の大きさは、内環状網体が動くと小さく変化し、外環状網体が動くと大きく変化するため、前記網目に張った膜の変化をより大きくし、泡の生成を促進させる。内環状網体及び外環状網体は、相対的に網目の大きさが異なればよいが、外環状網体の網目が小さいと内環状網体に向けて空気や水の流入が制限されやすくなるので、内環状網体の網目が相対的に小さく、逆に外環状網体の網目が相対的に大きい構成が好ましい。 More preferably, the foamed body has a double structure in which the annular network has an inner annular network having a relatively small mesh and an outer annular network having a relatively large mesh. For example, when the mesh of the inner ring network is relatively small and conversely the mesh of the outer ring network is relatively large, the size of the mesh formed by intersecting the two meshes is such that the inner ring network moves. Since the outer ring mesh body changes greatly when the outer ring network moves, the change of the film stretched on the mesh is increased to promote the generation of bubbles. The inner annular mesh body and the outer annular mesh body only need to have relatively different mesh sizes. However, if the mesh size of the outer annular mesh body is small, the inflow of air and water tends to be restricted toward the inner annular mesh body. Therefore, a configuration in which the mesh of the inner ring network is relatively small and conversely the mesh of the outer ring network is relatively large is preferable.

液状洗剤は、供給パイプを経て閉環状パイプへ供給されるため、特許文献１が開示する洗車具のように、洗剤タンクの底面に設けた供給ノズルに供給パイプを接続する構成にしても、閉環状パイプへ供給できる。この場合、水は洗車具と別に通常ホースにより車体に吹き付ける。また、供給パイプを接続する供給ノズルはそのまま設けながら、別途洗剤タンクの底面に水噴射ノズルを設け、前記洗剤タンクに接続した柄、洗剤タンクを貫通する給水パイプを通じて前記水噴射ノズルから弾性カバー内へ水を噴射するようにしてもよい。この場合、洗車具だけで液状洗剤及び水を供給できる。 Since the liquid detergent is supplied to the closed annular pipe through the supply pipe, even if the supply pipe is connected to the supply nozzle provided on the bottom surface of the detergent tank as in the car wash tool disclosed in Patent Document 1, the liquid detergent is closed. Can be supplied to an annular pipe. In this case, water is sprayed on the vehicle body by a normal hose separately from the car wash tool. In addition, while the supply nozzle for connecting the supply pipe is provided as it is, a water injection nozzle is separately provided on the bottom surface of the detergent tank, and the handle connected to the detergent tank and the water injection nozzle passing through the detergent tank are connected to the elastic cover from the water injection nozzle. Water may be jetted. In this case, liquid detergent and water can be supplied only by the car wash tool.

弾性カバーは、空気孔を開口し、弾性カバー内の負圧が保持され、毛皮洗浄体が車体に密着することを防止すると共に、一時的な負圧を解消するため、前記空気孔から弾性カバー内に対して空気を流入又は流出させて圧力変動を招き、液状洗剤を放出させ、また環状網体による泡立てを促進させるとよい。更に、弾性カバー内に対して流入又は流出する空気の量を大きくするため、弾性カバーの下周縁から母線方向に設けた多数のスリットで区画される多数の弾性片を形成し、弾性カバーの変形量を大きくするとよい。この場合、スリットが弾性カバーの内外を連通させることになるので、毛皮洗浄体に取付カバーを設け、前記取付カバーにより弾性カバーのスリットを覆わせて、塞ぐとよい。 The elastic cover opens the air hole, the negative pressure in the elastic cover is maintained, and the fur cleaning body is prevented from coming into close contact with the vehicle body. It is advisable to cause air pressure to flow into or out of the interior to cause pressure fluctuations, to release a liquid detergent, and to promote foaming by an annular net. Further, in order to increase the amount of air flowing into or out of the elastic cover, a large number of elastic pieces defined by a large number of slits provided in the generatrix direction are formed from the lower edge of the elastic cover, and the elastic cover is deformed. The amount should be increased. In this case, since the slit communicates the inside and outside of the elastic cover, it is preferable to provide a mounting cover on the fur washing body and cover the slit of the elastic cover with the mounting cover.

このほか、泡立て体は、弾性カバーの内面に設けた粗雑面を環状網体に摺接させたり、毛皮洗浄体の上面に設けた粗雑面を環状網体に摺接させたりするとよい。環状網体は、自身が変形することにより網目に形成した膜から泡を生成したり、二重構造の場合、内環状網体及び外環状網体の網目を交差させて形成される網目に形成した膜から泡を生成したりする。粗雑面は、環状網体に引っかかることにより、前記環状網体の変形を複雑にして、泡の生成を促進させる。これから、粗雑面は、環状網体に引っかかる摩擦を生ずる面であればよく、例えば環状網体がネットを丸めて構成している場合、前記環状網体を構成するネットを利用することができる。 In addition, the foamed body may have a rough surface provided on the inner surface of the elastic cover in sliding contact with the annular mesh body, or a rough surface provided on the upper surface of the fur cleaning body in sliding contact with the annular mesh body. Annular mesh forms bubbles from a film formed on the mesh by deforming itself, or in the case of a double structure, it forms a mesh formed by intersecting the meshes of the inner and outer annular meshes. Or generate bubbles from the finished film. When the rough surface is caught by the annular mesh, the deformation of the annular mesh is complicated, and the generation of bubbles is promoted. From this, the rough surface only needs to be a surface that causes friction that is caught by the annular mesh body. For example, when the annular mesh body is formed by rounding the net, the net constituting the annular mesh body can be used.

本発明は、比較的小型の自動車、例えば普通自動車を個人が洗車する場合に好適な洗車具を提供する。特に、本発明の洗車具は、水を吸わない環状網体から構成される泡立て体による泡立ちがよく、車体外面を傷つけずに泡を拡散させて汚れを落とす毛皮洗浄体と相俟って、優れた洗浄作用を発揮する。また、洗浄ヘッドは、洗剤タンクのほか重量物がないことから、取扱いも容易である。このほか、泡立て体は、泡を生成する本体である閉環状パイプ及び環状網体を毛皮洗浄体及び弾性カバーの間に保持させているだけなので、交換が容易である。本願発明の洗車具は、これら効果又は利点が相俟って、特に個人利用に適した洗車具になっている。 The present invention provides a car wash tool suitable for a person washing a relatively small automobile such as a normal automobile. In particular, the car wash tool of the present invention is well foamed by a foamed body composed of an annular net that does not absorb water, coupled with a fur washing body that diffuses foam without damaging the outer surface of the vehicle body and removes dirt, Exhibits excellent cleaning action. In addition, the cleaning head is easy to handle because there is no heavy load in addition to the detergent tank. In addition, the foamed body is easily exchanged because it only holds the closed annular pipe and the annular net body, which are the main bodies for generating foam, between the fur washing body and the elastic cover. The car wash tool of the present invention is a car wash tool particularly suitable for personal use due to the combination of these effects or advantages.

以下、本発明を実施するための形態について図を参照しながら説明する。本発明を適用した洗車具１は、図１に見られるように、外観は従来同種の洗車具、特に特許文献１が開示する洗車具とほとんど同じである。構成においても、図２に見られるように、揺動自在な柄12を接続した洗剤タンク２、前記洗剤タンク２の底面から錐台状に広がる弾性カバー３、前記弾性カバー３の下周縁に装着した毛皮洗浄体４とから洗浄ヘッド11を構成する。特許文献１が開示する洗車具との大きな相違点は、スポンジからなる泡立て体（特許文献１）に対し、図３に見られるように、供給パイプ51を接続した閉環状パイプ52を内環状網体53及び外環状網体54で包んで泡立て体５を構成している点にある。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIG. 1, the appearance of the car wash tool 1 to which the present invention is applied is almost the same as that of a conventional car wash tool, in particular, the car wash tool disclosed in Patent Document 1. Also in the configuration, as shown in FIG. 2, the detergent tank 2 to which the swingable handle 12 is connected, the elastic cover 3 spreading in a frustum shape from the bottom of the detergent tank 2, and the lower edge of the elastic cover 3 are attached. A cleaning head 11 is constructed from the finished fur cleaning body 4. A major difference from the car wash tool disclosed in Patent Document 1 is that a closed annular pipe 52 connected to a supply pipe 51 is connected to an inner annular network as shown in FIG. 3 with respect to a foamed body made of sponge (Patent Document 1). The foamed body 5 is configured by being wrapped by the body 53 and the outer annular net 54.

泡立て体５は、洗剤タンク２の供給ノズル211（後掲図６ほか参照）に始端が接続される供給パイプ51と、前記供給パイプ51の終端が接続され、複数の供給孔521を開口した閉環状パイプ52と、前記閉環状パイプ52に外嵌した内環状網体53及び外環状網体54とから構成される。供給パイプ51及び閉環状パイプ52は、弾性を備えた樹脂製パイプである。これにより、泡立て体５は、弾性カバー３及び毛皮洗浄体４を組み付けた後、毛皮洗浄体４の毛44に囲まれた開放下面から、閉環状パイプ52を弾性変形させながら弾性カバー３の内部へ押し込むことができる。供給パイプ51は、弾性カバー３の内部へ閉環状パイプ52、内環状網体53及び外環状網体54を押し込んだ後、始端を洗浄タンク２の供給ノズル211に接続する。 The foaming body 5 includes a supply pipe 51 having a start end connected to a supply nozzle 211 (see FIG. 6 and others) of the detergent tank 2, and a closed end in which a plurality of supply holes 521 are opened. The annular pipe 52 is constituted by an inner annular mesh body 53 and an outer annular mesh body 54 that are externally fitted to the closed annular pipe 52. The supply pipe 51 and the closed annular pipe 52 are resin pipes having elasticity. As a result, the foamed body 5, after assembling the elastic cover 3 and the fur cleaning body 4, the inner surface of the elastic cover 3 while elastically deforming the closed annular pipe 52 from the open lower surface surrounded by the hair 44 of the fur cleaning body 4. Can be pushed into. The supply pipe 51 pushes the closed annular pipe 52, the inner annular mesh 53 and the outer annular mesh 54 into the elastic cover 3, and then connects the start end to the supply nozzle 211 of the cleaning tank 2.

閉環状パイプ52は、樹脂製のＴ字接続ブロック55を基点に周方向等間隔に３個の供給孔521を半径内向きに開口している。供給孔521は、供給される液状洗剤６が直接取付カバー41の合成樹脂製織布に付着したり、縫着線にしみ込んだりしないように、半径内向きに開口することが望ましい。弾性を備えた閉環状パイプ52は、両端をＴ字接続ブロック55に拘束され、平面視円環状を形成し、外嵌する内環状網体53及び外環状網体54を全体として環状にする保形性を発揮する。供給孔521の大きさは、閉環状パイプ52の内径より小さく、前記保形性を損ねなければ自由であり、複数の供給孔521相互で大きさが異なってもよい。本例の供給孔521は、閉環状パイプ52の内径の半分程度であり、すべて同じ大きさである。 The closed annular pipe 52 has three supply holes 521 opened radially inward at equal intervals in the circumferential direction with a resin T-shaped connection block 55 as a base point. The supply hole 521 is desirably opened inward in the radial direction so that the supplied liquid detergent 6 does not directly adhere to the synthetic resin woven fabric of the mounting cover 41 or penetrate into the sewing line. The closed annular pipe 52 having elasticity is constrained at both ends by a T-shaped connection block 55 to form an annular shape in a plan view, and the inner annular mesh body 53 and the outer annular mesh body 54 that are fitted externally are kept annular. Demonstrate formality. The size of the supply hole 521 is smaller than the inner diameter of the closed annular pipe 52 and is free as long as the shape retaining property is not impaired. The sizes of the plurality of supply holes 521 may be different from each other. The supply holes 521 in this example are about half the inner diameter of the closed annular pipe 52 and all have the same size.

内環状網体53及び外環状網体54は、可撓性を備えた樹脂製糸で織成又は編成された樹脂製ネットである。本例は、相対的に内環状網体53の網目を小さく、外環状網体54の網目を大きくしている。内環状網体53は、閉環状パイプ52に対して拘束されておらず、内環状網体53及び外環状網体54は、互いに拘束されていないことから、いずれも周方向に動くことができる。内環状網体53及び外環状網体54が周方向に動く量は、後述するように、供給パイプ51を接続するＴ字接続ブロックの突起部分が内環状網体53及び外環状網体54を貫通しているため、内環状網体53及び外環状網体54が周方向に回転する程度ではなく、それぞれの変形が許される範囲で周方向にずれる程度である。 The inner ring net 53 and the outer ring net 54 are resin nets woven or knitted with flexible resin yarns. In this example, the mesh of the inner annular mesh 53 is relatively small and the mesh of the outer annular mesh 54 is enlarged. Since the inner annular net 53 is not constrained with respect to the closed annular pipe 52, and the inner annular net 53 and the outer annular net 54 are not constrained to each other, both can move in the circumferential direction. . As will be described later, the amount of movement of the inner annular mesh 53 and the outer annular mesh 54 in the circumferential direction is such that the protruding portion of the T-shaped connection block connecting the supply pipe 51 causes the inner annular mesh 53 and the outer annular mesh 54 to move. Since it penetrates, the inner annular mesh body 53 and the outer annular mesh body 54 do not rotate in the circumferential direction but shift in the circumferential direction within a range in which each deformation is allowed.

本例の泡立て体５は、中空のＴ字管路を内蔵する樹脂製のＴ字接続ブロック55の両端に、棒状に切り出した樹脂製パイプの両端を接続して閉環状パイプ52を構成し、前記Ｔ字接続ブロック55の突起部分に供給パイプ51の終端を接続している。内環状網体53及び外環状網体54は、長尺な長方形に切り出した樹脂製ネットの長辺を縫い合わせて筒状にし、閉環状パイプ52を構成する樹脂製パイプを挿通した後、短辺を縫い合わせて環状にしている。供給パイプ51は、内環状網体53及び外環状網体54を貫通して突出させたＴ字接続ブロック55の突起部分に終端を接続する。便宜上、図3は、供給パイプ51、閉環状パイプ52及びＴ字接続ブロック55が接続され、また樹脂製ネットを縫着して内環状網体53及び外環状網体54が完成した状態で図示している。 The foamed body 5 of this example is configured to form a closed annular pipe 52 by connecting both ends of a resin pipe cut out in a rod shape to both ends of a resin T-shaped connection block 55 containing a hollow T-shaped pipe line. The end of the supply pipe 51 is connected to the protruding portion of the T-shaped connection block 55. The inner ring net 53 and the outer ring net 54 are formed by stitching the long sides of the resin net cut into a long rectangular shape into a cylindrical shape and inserting the resin pipe constituting the closed ring pipe 52, and then the short side Are sewn into a ring shape. The supply pipe 51 connects the end to a protruding portion of a T-shaped connection block 55 that protrudes through the inner annular net 53 and the outer annular net 54. For convenience, FIG. 3 shows a state in which the supply pipe 51, the closed annular pipe 52, and the T-shaped connection block 55 are connected, and the resin net is sewn to complete the inner annular mesh 53 and the outer annular mesh 54. Show.

洗浄ヘッド11における泡立て体５以外の構成要素を、図４〜図８（図８は、左半分が取付カバー41の外面である防水カバー411のみを切断、右半分が弾性カバー３までを切断している）により説明する。洗剤タンク２は、上面を開放し、底面に下方を向けて供給ノズル211を突出させた平面視円形である樹脂製の筒状本体21から構成される。筒状本体21の開放された上面は、着脱自在な蓋22により塞がれる。蓋22は、洗浄タンク２の内外における圧力平衡のため、小さな通気孔221を設けている。液状洗剤６は、蓋22を開いて筒状本体21の内部に供給される。供給ノズル211は、筒状本体21の内部と外部とを繋ぐ連通孔を設けた突起であり、泡立て体５の供給パイプ51の始端を外嵌して接続する。本例の供給ノズル211は、特に開閉弁を設けていない。これから、筒状本体21の内部に貯留される液状洗剤６は、泡立て体５の閉環状パイプ52に設けた供給孔521を通じて加えられる負圧に応じて、適宜供給パイプ51へ流れ込む。 4 to 8 (FIG. 8 shows that the left half cuts only the waterproof cover 411, which is the outer surface of the mounting cover 41, and the right half cuts up to the elastic cover 3. Explained). The detergent tank 2 is composed of a cylindrical body 21 made of a resin having a circular shape in plan view with an upper surface opened and a supply nozzle 211 protruding downward toward the bottom surface. The opened upper surface of the cylindrical main body 21 is closed by a detachable lid 22. The lid 22 is provided with a small vent hole 221 for pressure balance inside and outside the cleaning tank 2. The liquid detergent 6 is supplied into the cylindrical main body 21 with the lid 22 opened. The supply nozzle 211 is a protrusion provided with a communication hole that connects the inside and the outside of the cylindrical main body 21, and is connected by externally fitting the start end of the supply pipe 51 of the foaming body 5. The supply nozzle 211 in this example is not particularly provided with an on-off valve. From this, the liquid detergent 6 stored inside the cylindrical main body 21 appropriately flows into the supply pipe 51 in accordance with the negative pressure applied through the supply hole 521 provided in the closed annular pipe 52 of the foamed body 5.

筒状本体21の底面は、下方に向けて内部と連通する供給ノズル211を囲むように、内周面に雌ネジ213を設け、円錐台側面に倣った傾斜面を下端周縁に形成した環状フランジ214を構成している。雌ネジ213は、手で掴んで廻すための羽根231を設け、上端周縁に前記環状フランジ214の下端周面と転写関係にある傾斜面を形成した環状雄ネジ23を螺着する。環状雄ネジ23は、中心部分が上下に連通しており、泡立て体５の供給パイプ51は、前記連通部分を通して供給ノズル211に接続する。弾性カバー３は、上部開口を囲む円錐台状の上縁部分を、前記環状フランジ214の下端周縁に形成した傾斜面と環状雄ネジ23の上端周縁に形成した傾斜面とに挟まれ、前記上縁部分を洗剤タンク２の底面に固定する。弾性カバー３は、環状雄ネジ23を緩めれば取り外し、交換できる。 The bottom surface of the cylindrical main body 21 is provided with a female screw 213 on the inner peripheral surface so as to surround the supply nozzle 211 communicating with the inside downward, and an annular flange having an inclined surface following the side surface of the truncated cone formed on the lower peripheral edge Consists of 214. The female screw 213 is provided with a blade 231 for grasping and turning by hand, and an annular male screw 23 having an inclined surface in transfer relation with the lower end peripheral surface of the annular flange 214 is screwed to the upper peripheral edge. The center part of the annular male screw 23 communicates vertically, and the supply pipe 51 of the foamed body 5 is connected to the supply nozzle 211 through the communication part. The elastic cover 3 is sandwiched between an inclined surface formed at the lower peripheral edge of the annular flange 214 and an inclined surface formed at the upper peripheral edge of the annular male screw 23 at the upper edge portion of the truncated cone surrounding the upper opening, The edge portion is fixed to the bottom surface of the detergent tank 2. The elastic cover 3 can be removed and replaced if the annular male screw 23 is loosened.

柄12は、金属製の棒体に樹脂製のグリップを装着した構成で、筒状本体21の側面に設けられた柄取付ボックス212へ先端を差し込み、柄取付ボックス212の左右側面を跨いで揺動軸121を前記先端に貫通させることにより、柄取付ボックス212の範囲内で上下に揺動する。本例の洗車具１は、液状洗剤６のみを供給する構成であるため、柄12を揺動自在に洗剤タンクに接続するのみである。しかし、例えば図９に見られるように、水道口（図示略）に接続される給水パイプ122を柄12に内蔵させ、筒状本体21の底面に設けた水噴射ノズル24に前記給水パイプ122を接続させて、環状雄ネジ23の連通部分を通して弾性カバー３内に水を供給できるようにしてもよい。このように水を供給できる洗車具１は、洗浄ヘッド11における洗剤タンク２の構造が変わるものの、弾性カバー３以下は同じであり、本例の洗車具１と共用できる。 The handle 12 has a structure in which a resin grip is attached to a metal rod, and the tip is inserted into the handle mounting box 212 provided on the side surface of the cylindrical main body 21 and swings across the left and right side surfaces of the handle mounting box 212. By causing the moving shaft 121 to penetrate the tip, the moving shaft 121 swings up and down within the range of the handle mounting box 212. Since the car wash tool 1 of this example is configured to supply only the liquid detergent 6, the handle 12 is simply connected to the detergent tank in a swingable manner. However, for example, as shown in FIG. 9, a water supply pipe 122 connected to a water tap (not shown) is built in the handle 12, and the water supply pipe 122 is connected to a water injection nozzle 24 provided on the bottom surface of the cylindrical main body 21. It may be connected so that water can be supplied into the elastic cover 3 through the communicating portion of the annular male screw 23. Although the structure of the detergent tank 2 in the cleaning head 11 changes in the car wash tool 1 that can supply water in this way, the elastic cover 3 and subsequent parts are the same and can be shared with the car wash tool 1 of this example.

弾性カバー３は、弾性を備えた樹脂板を円錐状にまるめ、重ねた両側縁部を母線に沿って並ぶ２個の鳩目により一体化して形成している。本例は、前記鳩目が内外に連通する空気孔31を構成する。本例の弾性カバー３は、泡立て体５に上方から押し当たる下方に、半径方向のスリットにより周方向に分割され、放射状に延びる多数の弾性片32を形成している。スリットは、多数の弾性片32を形成する隙間であると同時に、弾性片32を覆う取付カバー41の外面である防水カバー411の空気孔412から取り込んだ空気７を、更に弾性カバー３の内部に取り込む経路を形成する。弾性変形した弾性片32は、泡立て体５を上方から押さえつける（後掲図10参照）。 The elastic cover 3 is formed by concentrating a resin plate having elasticity in a conical shape and integrating two overlapping edge portions along two generatrixes along the generatrix. In this example, the eyelet 31 is configured to communicate with the inside and outside of the eyelet. The elastic cover 3 of this example forms a large number of elastic pieces 32 that are radially divided by radial slits and are radially extended below the foam cover 5 that presses against the foamed body 5 from above. The slit is a gap that forms a large number of elastic pieces 32, and at the same time, the air 7 taken in from the air holes 412 of the waterproof cover 411 that is the outer surface of the mounting cover 41 that covers the elastic pieces 32 is further introduced into the elastic cover 3. Form a path to capture. The elastic piece 32 elastically deformed presses the foaming body 5 from above (see FIG. 10 described later).

毛皮洗浄体４は、弾性片32を内外に挟み込んで弾性カバー３に装着する取付カバー41と、下面に毛44を植え込んだ合成樹脂製織布である環状基布43とを、合成樹脂製織布である円環状の帯布42により接続した構成である。毛44は、環状基布43に従って環状に並んでおり、内側に開口下面を形成して、泡立て体５により生成した泡を前記開口下面から外部に放出させる。帯布42は、取付カバー41の内面である上側ネット413と環状基布43の上面に設けた下側ネット431とを上下に離して、泡立て体５の収納空間を形成する。これから、泡立て体５の収納空間を確保するため、例えば樹脂製環状板を帯布42の内周面に宛てがい、例えば洗浄ヘッド11を車体８（後掲図10ほか参照）に押し付けた場合でも、帯布42が上下に潰れないようにするとよい。 The fur washing body 4 is composed of a synthetic resin weaving, which includes a mounting cover 41 that sandwiches an elastic piece 32 inside and outside and is attached to the elastic cover 3, and an annular base fabric 43 that is a synthetic resin woven fabric in which hair 44 is implanted on the lower surface. It is the structure connected by the annular | circular shaped cloth 42 which is cloth. The bristles 44 are arranged in a ring according to the annular base fabric 43, and an opening lower surface is formed on the inner side, and bubbles generated by the foaming body 5 are discharged from the opening lower surface to the outside. The band 42 separates the upper net 413 that is the inner surface of the attachment cover 41 and the lower net 431 provided on the upper surface of the annular base fabric 43 in the vertical direction to form a storage space for the foamed body 5. In order to secure the storage space for the foamed body 5, for example, even when the resin annular plate is directed to the inner peripheral surface of the band cloth 42 and the cleaning head 11 is pressed against the vehicle body 8 (see FIG. 10 and others below), for example. It is preferable that the band cloth 42 is not crushed up and down.

毛44は、液状洗剤６に耐性を有する素材、例えば羊の毛（ムートン）であり、弾性カバー３の内部で生成された泡が無意味に拡散することを抑制しながら、泡を車体８に擦り付けて洗浄作用を発揮させる。このため、毛44は、車体８に接しやすい環状基布43の下面に植え込まれている。本例の洗浄ヘッド11は、前記毛11がより広い範囲で車体８に接するように、環状基布42の外周縁に対して下面側から帯布42の下周縁を宛てがって縫着し、帯布42を上方に折り返して上周縁を上向きに立ち上げ、環状基布42の外周縁を半径外向きに折り曲げることにより、毛44が半径方向断面で広がるようにしている。これにより、例えば毛44が吸水して固まる虞を低減させている。 The hair 44 is a material having resistance to the liquid detergent 6, for example, sheep's hair (mouton), and suppresses the foam generated inside the elastic cover 3 from being diffused meaninglessly, while the foam is applied to the vehicle body 8. Rub to exert cleaning effect. For this reason, the hair 44 is implanted on the lower surface of the annular base fabric 43 that is easily in contact with the vehicle body 8. The cleaning head 11 of this example is sewn to the outer peripheral edge of the annular base fabric 42 from the lower surface side to the lower peripheral edge of the band cloth 42 so that the bristles 11 are in contact with the vehicle body 8 in a wider range. The band cloth 42 is folded upward, the upper peripheral edge is raised upward, and the outer peripheral edge of the annular base cloth 42 is bent radially outward so that the hair 44 spreads in the radial cross section. Thereby, for example, the possibility that the hair 44 absorbs water and hardens is reduced.

取付カバー41は、合成樹脂製織布である防水カバー411を外面とし、合成樹脂製ネットである上側ネット413を内面とする二重構造で、前記弾性片32の根元より上方と弾性片32の下端より下方（防水カバー411と上側ネット413とが一致する下周）をそれぞれ縫着して弾性片32を包み込み、弾性カバー３に装着する。本例は、弾性変形を一定限度で許容しながら周方向にずれる虞を低減するため、弾性片32を２枚１組として母線方向の縫着線414により区画している。防水カバー411は、周方向に3個の空気孔412を設けている。空気孔412の真ん中は、弾性カバー３の空気孔31の下側と一致させ、弾性カバー３の内部への空気の取込を容易にしている。取付カバー41は、防水カバー411と上側ネット413とが一致する下周縁に帯布42の上周縁を縫着している。 The mounting cover 41 has a double structure in which a waterproof cover 411 that is a synthetic resin woven fabric is used as an outer surface and an upper net 413 that is a synthetic resin net is used as an inner surface. The elastic piece 32 is wrapped around the lower part (the lower circumference where the waterproof cover 411 and the upper net 413 are aligned) from the lower end, and attached to the elastic cover 3. In this example, in order to reduce the possibility of shifting in the circumferential direction while allowing elastic deformation to a certain limit, the elastic pieces 32 are divided into a set of two pieces and sewn lines 414 in the generatrix direction. The waterproof cover 411 has three air holes 412 in the circumferential direction. The middle of the air hole 412 is aligned with the lower side of the air hole 31 of the elastic cover 3 to facilitate the intake of air into the elastic cover 3. In the attachment cover 41, the upper peripheral edge of the band cloth 42 is sewn to the lower peripheral edge where the waterproof cover 411 and the upper net 413 coincide.

環状基布43は、上面に合成樹脂製ネットである下側ネットを接着、固定している。これにより、泡立て体５は、取付カバー41の内面である上側ネット413と、前記環状基布43の上面に固定した下側ネット431とに挟まれる、自身の内環状網体53及び外環状網体54を摺り合わせるほか、前記外環状網体54を上側ネット413及び下側ネット431に摺り合わせて、泡立ちを促進させる。上側ネット413及び下側ネット431は、泡立て体５の外環状網体54に摺り合わせて泡立ちを促進させる粗雑面の一態様であり、網目の大きさは自由である。また、粗雑面であればよいため、例えば下側ネット431に代えて、環状基布43の上面に梨地面を形成してもよい。 The annular base fabric 43 has a lower net, which is a synthetic resin net, bonded and fixed to the upper surface. As a result, the foamed body 5 is sandwiched between the upper net 413 that is the inner surface of the mounting cover 41 and the lower net 431 that is fixed to the upper surface of the annular base fabric 43. In addition to rubbing the body 54, the outer annular net 54 is rubbed against the upper net 413 and the lower net 431 to promote foaming. The upper net 413 and the lower net 431 are one aspect of a rough surface that promotes foaming by sliding on the outer annular mesh body 54 of the foaming body 5, and the mesh size is free. Further, since a rough surface may be used, for example, a matte surface may be formed on the upper surface of the annular base fabric 43 instead of the lower net 431.

本例の洗車具１は、次のように使用し、泡立て体５により泡を生成する。準備作業として、蓋22を明けて洗浄タンク２に液状洗剤６を供給し、貯留する。液状洗剤６は、蓋22の通気孔221を通じて大気圧である洗剤タンク２の内部と、開放された毛皮洗浄体４の下面開口を通じて大気圧である弾性カバー３の内部とが圧力平衡しているため、供給パイプ51を通じて閉環状パイプ52へ一方的に供給されることがない。既述したように、本例の洗車具１は、水の供給手段がないため、別に通常ホース（図示略）により車体８に水を吹き付ける。そして、前記水を毛皮洗浄体４の毛44に吸水させて、泡立て体５に少しずつ水を供給できる状態にして、洗浄のための泡の生成を開始する。 The car wash tool 1 of this example is used as follows, and foam is generated by the foamed body 5. As a preparatory work, the lid 22 is opened and the liquid detergent 6 is supplied to the washing tank 2 and stored. The liquid detergent 6 has a pressure equilibrium between the inside of the detergent tank 2 that is at atmospheric pressure through the vent hole 221 of the lid 22 and the inside of the elastic cover 3 that is at atmospheric pressure through the lower surface opening of the opened fur washing body 4. Therefore, the supply pipe 51 does not supply the closed annular pipe 52 unilaterally. As described above, since the car wash tool 1 of this example does not have a water supply means, water is sprayed to the vehicle body 8 by a separate normal hose (not shown). Then, the hair 44 is absorbed by the hair 44 of the fur-cleaning body 4 so that water can be gradually supplied to the foamed body 5, and generation of bubbles for cleaning is started.

準備作業を終えた洗車具１において、まず柄12を持って洗浄ヘッド11を車体８に押さえつけると、図10に見られるように、弾性片32が弾性変形し、弾性カバー３を車体８に接近させて内部空間を小さくすると共に、毛皮洗浄体４を前記車体８に密着させる。これにより、弾性カバー３の内部にあった空気７は、弾性カバー３に設けた空気孔31を通じて外部へ排出される（図10中破線矢印参照）。この段階では、弾性カバー３の内部空間の減少に伴って空気７が排出されているだけなので、液状洗剤６に対する上記圧力平衡が維持され、未だ閉環状パイプ52へ液状洗剤６は供給されない。 In the car wash tool 1 after completing the preparatory work, when the cleaning head 11 is first pressed against the vehicle body 8 with the handle 12, the elastic piece 32 is elastically deformed and the elastic cover 3 approaches the vehicle body 8 as shown in FIG. Thus, the interior space is reduced, and the fur washing body 4 is brought into close contact with the vehicle body 8. As a result, the air 7 inside the elastic cover 3 is discharged to the outside through the air holes 31 provided in the elastic cover 3 (see broken line arrows in FIG. 10). At this stage, since the air 7 is only exhausted as the internal space of the elastic cover 3 decreases, the pressure balance with respect to the liquid detergent 6 is maintained, and the liquid detergent 6 is not yet supplied to the closed annular pipe 52.

洗浄ヘッド11を車体８に押し付けた状態から洗浄ヘッド11を車体８に押し付ける力を緩めると、弾性片32の復元力によって、図11に見られるように、弾性カバー３は車体８に遠ざかって、内部空間を大きくする（元に戻す）。このとき、吸水した毛皮洗浄体４は、車体８に密着した状態を保っているので、弾性カバー３の復元に伴って空気孔31から空気７を内部へ取り込もうとする。しかし、空気孔31が小さいため、弾性カバー３の内部は大気圧に比べて低い圧力、すなわち負圧を一時的に発生させる。これにより、液状洗剤６に対する圧力平衡も一時的に崩れ、閉環状パイプ52へ液状洗剤６が供給され、供給孔521から放出される。 When the force for pressing the cleaning head 11 against the vehicle body 8 from the state where the cleaning head 11 is pressed against the vehicle body 8 is loosened, the elastic cover 3 moves away from the vehicle body 8 as shown in FIG. Increase internal space (restore). At this time, since the water-absorbing fur washing body 4 is kept in close contact with the vehicle body 8, it tries to take in the air 7 from the air holes 31 as the elastic cover 3 is restored. However, since the air hole 31 is small, the inside of the elastic cover 3 temporarily generates a pressure lower than the atmospheric pressure, that is, a negative pressure. As a result, the pressure equilibrium with respect to the liquid detergent 6 is also temporarily broken, and the liquid detergent 6 is supplied to the closed annular pipe 52 and discharged from the supply hole 521.

本例の洗浄ヘッド11は、取付カバー41と環状基布43との間に帯布42を改装することにより、泡立て体５の収納空間を形成しており、上述のように、洗浄ヘッド11を車体８に押し付けても、前記収納空間が大きく潰れることはない。このため、液状洗剤６の供給は、専ら弾性カバー３の内部における一時的な負圧を利用している。しかし、泡立て体５の収納空間が大きく潰れるほど変形自在で、閉環状パイプ52が自己復元可能な弾性を備えている場合、洗浄ヘッド11を車体８に押し付けることにより、閉環状パイプ52を一時的に圧潰して液状洗剤６を供給孔521から放出させ、復元により供給パイプ51を通じて液状洗剤６の供給を受けるようにすることもできる。 The cleaning head 11 of this example forms a storage space for the foamed body 5 by refurbishing the band cloth 42 between the mounting cover 41 and the annular base fabric 43. As described above, the cleaning head 11 is Even if it is pressed against the vehicle body 8, the storage space does not collapse greatly. For this reason, the supply of the liquid detergent 6 exclusively uses a temporary negative pressure inside the elastic cover 3. However, when the storage space of the foamed body 5 is deformed so as to be largely crushed, and the closed annular pipe 52 has elasticity capable of self-restoring, the closed annular pipe 52 is temporarily pressed by pressing the cleaning head 11 against the vehicle body 8. Alternatively, the liquid detergent 6 can be discharged from the supply hole 521 by being crushed and supplied with the liquid detergent 6 through the supply pipe 51 by restoration.

こうして閉環状パイプ52の供給孔521から放出された液状洗剤６は、洗浄ヘッド11を車体８に押し付け、解放の繰り返しにより、毛皮洗浄体４の毛44から供給される水（図示略）と混ぜ合わされ、泡を生成する。具体的には、放出された液状洗剤が水と撹拌されて内環状網体53又は外環状網体54の網目に膜を張り、弾性カバー３の変形に伴う圧力変動によって前記内環状網体53又は外環状網体54の内外に流入又は流出する空気７が前記膜を膨らませて泡を生成する。このように、本発明の洗車具１は、液状洗剤６の供給と泡の生成とが同時進行するため、間断なく大量の泡を生成することができる。 Thus, the liquid detergent 6 discharged from the supply hole 521 of the closed annular pipe 52 presses the cleaning head 11 against the vehicle body 8 and mixes with water (not shown) supplied from the hair 44 of the fur cleaning body 4 by repeated release. To produce bubbles. Specifically, the discharged liquid detergent is agitated with water to form a film on the inner annular mesh 53 or the outer annular mesh 54, and the inner annular mesh 53 is caused by pressure fluctuation accompanying deformation of the elastic cover 3. Alternatively, the air 7 flowing in or out of the outer annular net 54 inflates the film to generate bubbles. Thus, since the supply of the liquid detergent 6 and the generation of bubbles proceed simultaneously, the car wash tool 1 of the present invention can generate a large amount of bubbles without interruption.

水と撹拌された液状洗剤６が形成する膜は、内環状網体53又は外環状網体54それぞれの網目だけでなく、内環状網体53及び外環状網体54それぞれの網目を交差させて形成される仮想的な網目にも形成される。本例の泡立て体５は、相対的に内環状網体53の網目が小さく、逆に外環状網体54の網目が大きいため、両者の網目が交差して形成される網目の大きさは、内環状網体53が動くと小さく変化し、外環状網体54が動くと大きく変化する（図12中、内環状網体53及び外環状網体54の網目の重なり具合を参照）。これにより、大小さまざまな膜が形成され、泡の生成が促進させる。 The film formed by the liquid detergent 6 stirred with water crosses not only the meshes of the inner annular mesh 53 or the outer annular mesh 54 but also the meshes of the inner annular mesh 53 and the outer annular mesh 54, respectively. A virtual mesh is also formed. In the foamed body 5 of this example, the mesh of the inner annular mesh 53 is relatively small, and conversely the mesh of the outer annular mesh 54 is large. When the inner annular net 53 moves, it changes slightly, and when the outer annular net 54 moves, it changes greatly (see the overlapping state of the meshes of the inner annular net 53 and the outer annular net 54 in FIG. 12). Thereby, large and small films are formed, and the generation of bubbles is promoted.

また、本例の洗車具１は、図12に見られるように、弾性カバー３の内面にあたる取付カバー41の内面に粗雑面として上側ネット413を設け、同じく毛皮洗浄体４の環状基布43の上面に粗雑面として下側ネット431を設けている。これにより、上側ネット413及び下側ネット431それぞれは、弾性カバー３の変形に際して動く外環状網体54に引っかかり、直接的に外環状網体54の変形を変化のある複雑なものにし、前記外環状網体54を介して間接的に内環状網体53の変形を変化のある複雑なものにして、泡の生成を促進している。外環状網体５に対する上側ネット413及び下側ネット431の引っかかりは、泡立て体５の大きな位置ズレを防止する働きも有する。 Further, as shown in FIG. 12, the car wash tool 1 of this example is provided with an upper net 413 as a rough surface on the inner surface of the mounting cover 41 corresponding to the inner surface of the elastic cover 3. A lower net 431 is provided as a rough surface on the upper surface. As a result, each of the upper net 413 and the lower net 431 is caught by the outer annular mesh body 54 that moves when the elastic cover 3 is deformed, and the deformation of the outer annular mesh body 54 is directly changed and complicated. The generation of bubbles is promoted by making the deformation of the inner annular network 53 indirectly complicated via the annular network 54. Engagement of the upper net 413 and the lower net 431 with respect to the outer annular net body 5 also has a function of preventing a large positional deviation of the foamed body 5.

粗雑面は、外環状網体54に引っかかればよいため、本例の上側ネット413及び下側ネット431に代えて、単なる梨地面として形成することも考えられる。しかし、上側ネット413及び下側ネット431は、泡立て体５の内環状網体53及び外環状網体54が密に重なり合って接触した場合でも、空気７が回り込む隙間を残すので、網目に張った膜に対して前記空気７を送り込み、泡の生成を助ける働きを有する。これから、粗雑面として本例のような上側ネット413及び下側ネット431が好ましい。 Since the rough surface only needs to be caught by the outer annular net 54, it may be considered that the rough surface is formed as a plain surface instead of the upper net 413 and the lower net 431 in this example. However, the upper net 413 and the lower net 431 are attached to the mesh because the air ring 7 is left around even when the inner annular net 53 and the outer annular net 54 of the foamed body 5 are in close contact with each other. The air 7 is fed into the membrane and has a function of helping to generate bubbles. Therefore, the upper net 413 and the lower net 431 as in this example are preferable as rough surfaces.
