John Holman之題為「HOSE REEL FRAME AND GUIDE ARM」的非臨時申請案第一一號及與此申請案同曰申請之 發明者Anthony Shakal與John Holman之題為「HOSE REEL LATCH」的非臨時申請案第—號。 【先前技術】 軟管捲盤通常用於固結載送流體之軟管。經捲繞的軟管 佔據較小空間，且更不可能與圍繞物_。卫業軟管捲盤 通常以扭力彈簀或平衡重量偏壓以在附接至捲盤的軟管上 不存在延伸力下自動捲攏》 軟管捲盤通常包括三個主要組件：捲筒、支架及導引 臂。軟管捲盤之捲筒通常包括具有圓柱壁及軸向相對側壁 之轂。側壁與圓柱壁一起界定經捲繞的軟管儲存於其令之 環形固持區域。軟管之敎端通常通過或附接至圓柱壁上 的軟管安裝件。此軟管安裝.件通常係經成斜角以當軟管盤 繞捲筒時防止軟管過度彎曲。很多軟管捲盤亦包含支撐或 錨定捲筒之支架或支架》此等支架可附接至捲筒之一^或 兩側。軟管支架必須可支撐裝載有軟管的捲筒之全部重量 以及與捲繞及展開軟管相關聯的任何張力。—些軟管捲2 亦包含導引臂以導引軟管之收捲，藉此確保軟管適當地盤 153563.doc 201144202 繞至捲筒上。如同支架，導引臂可附接至軟管捲盤之一側 或兩你卜大多數導引臂可選擇地附接以便容許軟管在一角 度範圍下收捲與展開。 過去些軟管捲盤具有内含棘輪閃鎖總成以防止軟管 捲盤在使用時回縮或重新收捲軟管。此等㈣總成通常包 含軟管捲盤支架或導弓之一者上的棘爪及接附至捲筒之 -側的有齒棘輪元件。通常歸因於增加的成本及需要的製 &時間’先則軟管捲盤亦包含用於支架或導引臂（但非兩 者）上的棘爪之安裝件。棘爪嗔合棘輪元件以限制捲筒之 旋轉：防止捲筒收捲。藉此等閃鎖總成，經閃鎖的軟管係 藉由首先猶稍展開軟管以使棘輪元件與棘爪脫離而回縮。 若當軟管完全展開時棘爪喷合，這是已知的難題。在此一 凊況下’不可能在不拆卸軟管捲盤下解鎖及重新收捲軟 管。可能藉由製造在捲筒與軟管安裝件之徑向相對側上的 棘輪元件並在導？lf上安裝棘爪而確保此情形永不發生。 當軟管完全展開時，軟管安裝件將與導引臂徑向對齊。因 此，當軟管完全延伸時，安裝於導引臂上的棘爪可永不扣 住相對於軟管安裝件之棘輪元件。當軟管捲盤不包含導引 臂時’便無法採用此解決方案。在其中忽略導引臂以節省 費用、重董或空間之應用中’問鎖必須安裝於別處或無閂 鎖。 . 軟管捲盤較佳為強硬、小型化且容易組裝。過去，軟管 捲盤支架有時經構建具有轴向向外延伸支樓凸緣，且軟管 捲盤之捲筒有時經構建具有軸向向外成斜角碟形側壁。此 153563.doc 201144202 等構造提供額外強度，但相較於平坦捲筒體積較大，且因 此使具有較大佔據面積之較大支架成為必需。在製造期間 及製造之後’容易組裝均重要；特定言之，期望軟管捲盤 可容易調適於不同工作條件及應用。 【發明内容】 本發明係關於一種具有撐托一圓柱壁之二凹碟形側壁之 軟管捲盤之捲筒。隨該等側壁徑向向外延伸，該等側壁軸 向向内成斜角而朝向彼此會聚。 【實施方式】 I.概述 圖la及圖lb描繪軟管捲盤總成1〇，其包括捲筒i2(具有 側壁108a及108b)、支架14(具有支架底座26及支架側28a及 28b並具有凸緣30及螺樁29)、導引臂16(具有l形件32及I形 件34 ’每一者具有孔或凹口 31)、軟管18、孔20、錫22、 安裝硬體23、棘輪元件24及棘爪25(以虛線繪示於導引臂 16後面）。圖la及圖lb亦繪示捲繞方向w及展開方向UW。 捲筒12旋轉以收捲及展開盤繞一中央圓柱表面並介於捲筒 12之該等側之間的軟管18。 捲商12包括轴向較1〇4(圖la或圖lb中不可見；見圖2)及 徑向延伸第一側壁108a及第二側壁i〇8b。如所描繪，捲筒 12在捲繞方向W轉動以收捲並在展開方向uw轉動以展開 軟管18。在其他實施例中’捲筒12可經製造以在相反方向 收捲及展開軟管18。支架14支撐捲筒12及導引臂16。導引 臂16自支架14延伸以如所示固持軟管18。捲筒12係由安裝 153563.doc 201144202 硬體23可旋轉地附接至支架14,安裝硬體23在一些實施例 中為行進穿過捲筒12、支架側28a及28b及導引臂16之件32 及34之一中央輪轴或銷。在一實施例中，捲筒丨2係經偏壓 (由舉例而言一扭力彈簧）以在不存在一相反力下在捲繞方 向W旋轉，藉此收捲軟管18 »隨捲筒12之側l〇8a及108b徑 向向外延伸，側l〇8a及108b軸向向内成斜角，而側1〇仏成 斜角朝向側108b，且反之亦然。此成斜角構造強化捲筒12 並避免側壁108a及108b與凸緣30(下文論述）之間之接觸。 支架14包括水平支架底座26及垂直支架側28a及28b。支 架側28a及28b係錨定至形成支架14之基礎之支架底座26。 支架側28a係焊接至支架底座26以形成一單一 L形支架件。 支架侧28b未焊接至支架底座26，但當組裝支架14時固持 至支架底座26。包括支架側28a及支架底座26之該L形件與 支架側28b(—I形件）組合以形成支架14之U形。支架側28a 及28b經由安裝硬體23支撐捲筒12及導引臂16，如先前所 論述。底座26相較於導引臂16並未軸向延伸更寬》支架側 28a及28b併入凸緣30以強化支架14。凸緣30位於側28a及 28b之内面上，且在支架底座26處最寬，垂直成錐形於支 架側28a及28b内。因為凸緣30位於側28a及28b之該等内面 上，故凸緣30並未增加軟管捲盤！〇之寬度。如先前所論 述’捲筒30之側108a及l〇8b軸向向内成斜角朝向彼此，藉 此避免與凸緣30接觸。 導引臂16亦附接至支架14，並繞著捲筒12之該軸線但獨 立於捲筒12旋轉。導引臂16可經由一個或多個緊固件直接 153563.doc 201144202 附接至支架14或由安裝硬體23錨定至支架14。在一實施例 中，螺樁29係以一圓形陣列配置於支架14上，並耦合至導 引臂16中的孔或凹口 31以在預定義角度之一範圍下錯定導 引臂16。軟管18之自由端通過導引臂16中的孔20，但因為 軟管18上之錨22(其過大以致難以裝配穿過孔2〇)而不可完 全回縮入捲筒12内。錨22可為繞著軟管18固定的一橡膠或 塑膠阻擋件。導引臂16由兩件組成：包括導引臂16之一側 及前部之L形件3 2及包括導引臂16之相對側之I形件3 4。L 形件32及I形件34係一起固定以如所示形成導引臂丨6。 棘輪元件24係接附至捲筒12，並與導引臂16上的棘爪25 接合以防止軟管1 8不當地回縮。棘輪元件24僅如所示橫跨 捲筒12之一部分徑向弧’且因此僅在捲筒12之每次旋轉之 一片段與棘爪25對齊。當棘輪元件24在UW方向旋轉以與 棘爪25對齊時，棘爪25與棘輪元件24扣住，施加防止捲筒 12在W方向之旋轉之一反旋轉力。當棘輪元件24與棘爪25 未對齊時或旋轉入W方向以與棘爪25對齊時，棘爪25並未 扣住棘輪元件24，且並不防止捲筒12在任一方向旋轉。雖 然在圖la中顯示棘爪25安裝於導引臂16上，但棘爪25或者 可安裝於支架14上。 Π.捲筒12 圖2係包括軸向轂ι〇4(具有具軟管安裝件112之外圓柱壁 106)、側壁i〇8a(具有外環形唇緣n8a)及側壁i〇8b(具有外 環形唇緣118b及環形脊114)之捲筒12(具有捲筒半部丨02&及 102b)之一正視圖。外圓柱壁1〇6及側壁1〇8&及1〇815一起界 I53563.doc 201144202 定環形軟管固持區域11 〇。 如先前所陳述，捲筒12係由軸向轂104及側壁108&及 l〇8b組成。軸向轂1〇4包括内端壁12〇(圖2中不可見；見圖 3)及外圓柱壁106。外圓柱壁106係軸向轂1〇4之徑向最外 圓柱部。側壁1083及108b係自外圓柱壁1〇6之該等邊緣徑 向向尔延伸之環形凸緣。連同側壁1〇8a&1〇8b，外圓柱壁 106界定軟管固持區域11〇(軟管18盤繞以用於儲存之一環 形空間）。在一實施例中，捲筒12係以兩半部形成。第一 捲筒半部102a包含第一側壁l〇8a及外圓柱壁部106a。第二 捲筒半部102b包含第二側壁l〇8b及外圓柱壁部1061^捲筒 12係藉由將第一捲筒半部丨〇2a及第二捲筒半部1〇2b焊接或 螺合在一起而形成。 軟管18安裝於外圓柱壁1〇6上並在軟管安裝件112處，軟 官安裝件112係逆時針成斜角以便在軟管18連接至軟管安 裝件112之部位不會過度彎曲軟管18。在一實施例中，軟 管安裝件112係通過圓柱壁1〇6(軟管18係螺合穿過圓柱壁 106)之一通道。在另一實施例中，軟管安裝件112係軟管 18之端之一附接點，且抽向較1〇4進一步包括連接裝置 以輸送來自一流體源之流體至軟管18内。在一實施例中， 棘輪元件24係安裝於捲筒12與軟管安裝件112之一徑向相 對側上以避免棘輪元件2 4之鎖定。 當軟管係穿過導引臂16之孔20收捲至捲筒〗2上（見圖la 及圖lb)時，軟管以一金字塔形狀自然層疊而很少於外圓 柱壁106處寬於四個軟管寬度，且隨著軟管徑向向外堆疊 153563.doc 201144202 而大體上變窄。因此’外圓柱壁106係經設計以僅稍大於 四個軟管寬度’因為額外寬度會增加軟管捲盤總成丨〇之體 積而無益處。 環形脊114自外圓柱壁106軸向向外延伸以提供一徑向平 坦表面以供捲筒12之一罩蓋（未顯示）之附接。結合圖3更詳 細描述環形脊114。隨側壁1 〇8a及1 〇8b徑向向外延伸，側 壁l〇8a及l〇8b軸向向内成斜角：侧壁丨083係成斜角朝向側 壁108b ’且反之亦然。此成斜角構造強化捲筒丨2而不增加 捲筒寬度。 圖3係捲筒12之一側視圖’其顯示側壁丨08b、環形脊 114、安裝孔116、外環形唇緣11扑、具有安裝位置122之 内端壁120及棘輪元件24。如先前所論述，轴向轂104包括 内端壁120及外圓柱壁1〇6。内端壁120係橫跨捲筒12内部 並在圓柱壁106徑向向内之一平坦徑向表面（見圖2)。内端 壁120亦包含安裝位置122。安裝硬體25係固定於安裝位置 122以支撐支架14上的捲筒12。在一實施例中，安裝硬體 24係一軸或銷’且安裝位置122係通過内端壁120(安裝硬 體裝配穿過内端壁120)之一通道。下文更詳細描述安裝位 置 122。 環形脊114係側壁1 〇8b之一區域，安裝孔116係經鑽孔穿 過該區域。孔116容許一罩蓋（未顯示）螺合或錨定至環形脊 114處的側壁108b(若如此所需）。環形脊1 μ位於外圓柱壁 106之一端處’並自外圓柱壁1〇6徑向向外直接延伸以便提 供該罩蓋之一平坦安裝表面。雖然顯示環形脊丨丨4在側 153563.doc •9- 201144202 108b上，但環形脊114或者可位於側108a上。 側壁108a及l〇8b之徑向向外延伸部轴向向外彎折成外環 形唇緣118a及118b’此強化捲筒12。第二側壁1〇813終止於 第二外環形唇緣118b ’其軸向彎折遠離軟管固持區域η 〇 及第一側壁1 〇8a。類似地，第一側壁1 〇8a(圖3中不可見； 見圖2及'圖4)終止於第一外環形唇緣118a，其軸向彎折遠 離軟官固持區域11〇及第二側壁1〇8b。因為隨側壁1〇8&及 l〇8b徑向向外延伸’側壁1〇8&及1〇81)軸向向内成斜角，故 外環形唇緣118並未增加捲筒12的總體寬度。棘輪元件24 係螺合或鉚合至側壁1 〇8b以與棘爪25相互作用，如先前所 論述。圖3亦顯示截面線4-4，其通過捲筒12之該軸線。 圖4係沿著圖3之截面線4-4之捲筒12之一分解戴面圖。 圖4描繪捲筒12 ’其包含外圓柱壁1〇6、側壁i〇8a及i〇8b、 外環形唇緣118a及118b、内端壁區段120a及120b及安裝位 置122、軸環124及孔126。圖4顯示為清楚分解的捲筒半部 l〇2a及l〇2b。當組裝捲筒I2時，捲筒半部102&及1〇21)係附 接在一起，如先前所論述。安裝硬體25通過安裝位置122 以錨定捲筒12至支架14。 在其中捲筒12係由兩半部形成之實施例中，内端壁丨2〇 可为為一鄰接區段：第一内端壁區段I20a(其為第一捲筒 半部102a之一部分）及第二内端壁區段i2〇b(其為第二捲筒 半部102b之一部分）。此等區段係栓接或焊接在一起以連 接捲筒半部102a至捲筒半部102b。在一實施例中，第一内 端壁區段120a包含孔126，且第二内端壁區段i2〇b包含轴 153563.doc 201144202 環124。孔126係第二内轴向端壁區段12〇&之一中央孔，並 足夠大以容納軸環124 ^軸環124係第二内軸向端壁區段 120b之一中央軸向延伸部，其通過孔126並形成安裝硬體 25之一軸頸。在另一實施例中，軸環124與孔126之位置反 轉：轴環124位於第一内端壁區段12〇&上，而孔126位於第 一内而壁區#又120b中。一軸套或軸承係***軸環丨24中以 當捲筒12旋轉時支撐捲筒12 β 如先前所論述，為了增加的強度，隨側壁1〇8徑向向外 延伸，側壁108軸向向内傾斜。此向内傾斜係經設計以匹 配軟管18繞著内圓環1 〇6之先前提到的自然金字塔堆疊輪 廓且因此並不阻止收捲。第一側壁1〇8a之徑向最外邊緣終 止於第一外環形唇緣11 8a中，且第二側壁丨〇8b之徑向最外 邊緣終止於第二外環形唇緣11813中。外環形脊118&及118卜 進一步強化捲筒12。 圖4亦指示區域R，其涵蓋外圓柱壁1〇6及第二側壁1〇8b 之一區段。 圖5係來自圖4之區域R之一放大圖。圖5顯示内圓環1〇6 之一部分及具有外環形唇緣、環形脊114及一安裝孔 116之側壁l〇8b。環形脊114係藉由自外圓柱壁1〇6之最外 延伸部直接徑向向外延伸側壁1081)達一短距離而非在自内 圓環106b與側壁108a之交叉處至外環形唇緣118&之整個徑 向跨度之上軸向向内傾斜側壁l〇8b而形成。一捲筒罩蓋可 藉通過安裝孔116之螺樁附接至側壁丨〇扑。如圖5可見，第 二側壁108b之轴向向内傾斜防止第二外環形唇緣丨18b增加 153563.doc 201144202 捲琦12之軸向體積。同樣適用於第一側壁丨〇8a及第一外環 形唇緣118a。此緊致設計亦使凸緣3 〇(上文參考圖丨所論述） 可面向轴向向内而不接觸側壁1〇8&或1〇8b，藉此進一步減 小軟管捲盤10之總體軸向體積。 ΠΙ.支架14 圖6係來自圖1之支架底座26之一平面圖，其描繪緊固突 片202、脊狀表面204、第一侧附接區域2〇6及第二側附接 區域208。支架底座26在一實施例中為一片經按壓或鑄造 金屬。支架側28a係焊接於第一側附接區域2〇6處之適當位 置。支架側28b係經由螺合穿過緊固突片2〇2的緊固件附接 至第二側附接區域208處之支架底座26。緊固突片202在一 實施例中係由支架底座26衝壓並自底座支架26以90度彎曲 以突出平行於支架側28b。在另一實施例中，緊固突片202 係焊接至支架底座26上的獨立金屬件。脊狀表面204係經 衝壓或鑄造於支架底座26内以強化支架14抵抗彎曲之一凸 起區域。 圖7a及圖7b分別係經連接以形成一 l形件的支架側28a及 支架底座26之外部側視圖及正視圖。圖3a描繪支架底座 26、及具有凸緣30a、安裝點21〇a、脊212a及螺樁29之支

架14並支撐側l〇8a。凸緣30a係對角向内成斜角朝向軟管 捲盤總成10之内部’如由圖6上之第一側附接區域2〇6所指 示。脊212a進一步強化支架側28a抵抗彎曲。如圖2a所 示，脊212a包括延伸入側28a之波紋。緊固突片202具有緊 固件孔214以容許螺紋緊固件通過緊固突片2〇2以固定框架 支架側28b(見圖la及圖lb)。螺樁29幫助固定導引臂16至支 架14，如下文參考圖i〇a至圖i〇d所述。 圖8係支架側28b之一外部側視圖，其描繪凸緣3〇b、安 裝點21 Ob、脊212b及緊固件孔214b。凸緣3Ob及脊212b恰 如凸緣30a及脊212a強化支架側28a般強化支架側28b。安 裝硬體23附接至或饋送穿過安裝點21〇a，藉此連接捲筒12 至支系14之兩侧。凸緣3Ob中的緊固件孔214b容許支架側 28b安裝於緊固突片102上。緊固件216(圖8中未顯示；見 圖9)通過緊固件孔214以固定框架支架側28b至支架底座 26 ’將支架側28b固持於圖6之侧附接區域2〇8内。緊固件 216可為螺樁、螺釘或其他螺紋緊固件。 圖9係支架14之一透視圖，其包括支架底座26、支架側 28a及28b(分別具有安裝點21〇a及210b及螺樁29)、緊固件 孔214及緊固件216。如先前所論述，支架側2仏係焊接至 支架底座26以形成一 L形件。支架側28b係藉由***緊固件 216穿過緊固件孔214a(不可見）及214b而附接至此L形件。 此構造簡化捲筒12之安裝（經由附接至或饋送穿過安裝點 210a及210b的安裝硬體23)。只要支架側28b固定於適當位 置，支架側28a及28b—起將捲筒12鎖定於適當位置（使捲 153563.doc -13· 201144202 筒12自由旋轉）。安裝或移除捲筒12係藉由自緊固件孔214 去螺合緊固件216、自安裝點21 Ob移除安裝硬體23及使支 架側28b與支架底座26及安裝硬體23脫離而實現。螺樁29 與凹口或孔3 1 (見圖1 a及圖1 b)相互作用以將導引臂丨6固持 於相對於支架14之適當位置。 IV.導引臂16 圖10a至圖l〇d繪示導引臂16之L形件32。圖l〇a、圖 1

32被附接至I形件34。脊308延伸側區段302的長度，並強 化導引臂16抵抗彎曲。如圖1 〇a所示，脊3〇8包括延伸入側 區段302内之波紋。 導引臂16係在附接區域31〇處附接至支架14。在一實施 例中，導引臂16上的孔31容納支架14上的螺樁29。螺樁29 及孔3 1係以一圓形陣列配置，並以相對於捲筒丨2之預定角 度之一範圍内之任何角度下將導引臂16固持於適當位置。 當L·形件32附接至I形件34時，導引臂16可以繞著捲筒12之 該軸線（由安裝硬體23界定）之離散角度間隔旋轉，使得螺 樁29在一所需位置處支撐導引臂16。在一些實施例中，導 引臂16可進一步或者由夾具或螺樁緊固件支撐，或可由安 153563.doc •14- 201144202 裝硬體23錨定於適當位置。 軟管1 8通過前孔3 12，且因此係由經約束以從一受限角

Anthony Shakal and John Holman of the same application Case number - number. [Prior Art] A hose reel is generally used to consolidate a hose carrying a fluid. The wound hose occupies less space and is less likely to surround the enclosure. The sanitary hose reel is typically biased with a torsion or balance weight to automatically roll up without the presence of an extension force on the hose attached to the reel. The hose reel typically includes three main components: a reel, Bracket and guide arm. The reel of the hose reel typically includes a hub having a cylindrical wall and axially opposite side walls. The side wall, together with the cylindrical wall, defines a wound hose that is stored in its annular holding area. The end of the hose is typically passed or attached to a hose mount on the cylindrical wall. This hose mount is usually angled to prevent excessive bending of the hose when the hose is wound around the drum. Many hose reels also include brackets or brackets that support or anchor the reel. These brackets can be attached to one or both sides of the reel. The hose bracket must support the full weight of the hose loaded with the hose and any tension associated with the coiled and unfolded hose. Some of the hose rolls 2 also contain guiding arms to guide the winding of the hoses, thereby ensuring that the hoses are properly wound around the rolls 153563.doc 201144202. Like the bracket, the guiding arm can be attached to one side of the hose reel or both of the main guiding arms can be selectively attached to allow the hose to be wound and unfolded over a range of angles. Previous hose reels have a ratchet flash lock assembly that prevents the hose reel from retracting or rewinding the hose during use. These (four) assemblies typically include a pawl on one of the hose reel brackets or the guide bow and a toothed ratchet element attached to the side of the spool. Usually due to the increased cost and the required system &time', the hose reel also includes mountings for the pawls on the bracket or the guiding arm (but not both). The pawl kneads the ratchet element to limit the rotation of the reel: preventing the reel from being wound. By means of the flash lock assembly, the flash-locked hose is retracted by first unfolding the hose to disengage the ratchet element from the pawl. This is a known problem if the pawl is sprayed when the hose is fully deployed. Under this circumstance, it is impossible to unlock and rewind the hose without disassembling the hose reel. It is possible to manufacture the ratchet element on the diametrically opposite side of the reel and hose mount and guide it. Install the pawl on lf to ensure that this never happens. When the hose is fully deployed, the hose mount will be radially aligned with the guide arm. Therefore, when the hose is fully extended, the pawl mounted on the guide arm can never buckle the ratchet member relative to the hose mount. This solution cannot be used when the hose reel does not contain a guide arm. In applications where the guiding arm is omitted to save cost, heavy weight or space, the Q lock must be installed elsewhere or without a latch. The hose reel is preferably tough, compact, and easy to assemble. In the past, hose reel brackets have sometimes been constructed with axially outwardly extending branch flanges, and the reel of the hose reel is sometimes constructed with axially outwardly angled dished side walls. This configuration provides additional strength, but is relatively bulky compared to a flat reel, and thus necessitates a larger bracket with a larger footprint. Easy assembly during manufacturing and after manufacture is important; in particular, hose reels are expected to be easily adaptable to different operating conditions and applications. SUMMARY OF THE INVENTION The present invention is directed to a reel having a hose reel that supports two concave dish-shaped side walls of a cylindrical wall. With the sidewalls extending radially outward, the sidewalls are angled inwardly toward each other and converge toward each other. [Embodiment] I. Overview FIGS. 1a and 1b depict a hose reel assembly 1A including a reel i2 (having side walls 108a and 108b), a bracket 14 having a bracket base 26 and bracket sides 28a and 28b and having Flange 30 and stud 29), guiding arm 16 (having l-shaped member 32 and I-shaped member 34' each having a hole or recess 31), hose 18, hole 20, tin 22, mounting hardware 23 The ratchet element 24 and the pawl 25 (shown in phantom behind the guiding arm 16). Figures la and lb also show the winding direction w and the unfolding direction UW. The spool 12 is rotated to wind and unwind the hose 18 that is wound around a central cylindrical surface and between the sides of the spool 12. The volume 12 includes an axial direction of 1 〇 4 (not visible in Figure la or Figure lb; see Figure 2) and a radially extending first side wall 108a and a second side wall i 〇 8b. As depicted, the reel 12 is rotated in the winding direction W to wind up and rotate in the unfolding direction uw to unfold the hose 18. In other embodiments, the spool 12 can be manufactured to wind and unwind the hose 18 in the opposite direction. The bracket 14 supports the spool 12 and the guide arm 16. The guide arm 16 extends from the bracket 14 to hold the hose 18 as shown. The spool 12 is rotatably attached to the bracket 14 by a mounting 153563.doc 201144202 hardware 23 that, in some embodiments, travels through the spool 12, the bracket sides 28a and 28b, and the guide arm 16 One of the 32 and 34 central axles or pins. In one embodiment, the reel 2 is biased (by way of example a torsion spring) to rotate in the winding direction W in the absence of an opposing force, thereby winding the hose 18 » with the reel 12 The sides l8a and 108b extend radially outwardly, the sides l8a and 108b are angled inwardly at an oblique angle, and the side 1〇仏 is angled toward the side 108b, and vice versa. This beveled construction reinforces the reel 12 and avoids contact between the side walls 108a and 108b and the flange 30 (discussed below). The bracket 14 includes a horizontal bracket base 26 and vertical bracket sides 28a and 28b. The bracket sides 28a and 28b are anchored to a bracket base 26 that forms the basis of the bracket 14. The bracket side 28a is welded to the bracket base 26 to form a single L-shaped bracket member. The bracket side 28b is not welded to the bracket base 26, but is retained to the bracket base 26 when the bracket 14 is assembled. The L-shaped member including the bracket side 28a and the bracket base 26 is combined with the bracket side 28b (-I-shaped member) to form the U-shape of the bracket 14. Bracket sides 28a and 28b support spool 12 and guide arm 16 via mounting hardware 23, as previously discussed. The base 26 does not extend axially wider than the guide arm 16. The bracket sides 28a and 28b are incorporated into the flange 30 to reinforce the bracket 14. The flange 30 is located on the inner faces of the sides 28a and 28b and is the widest at the bracket base 26 and is vertically tapered within the bracket sides 28a and 28b. Since the flange 30 is located on the inner faces of the sides 28a and 28b, the flange 30 does not increase the hose reel! The width of the 〇. As previously discussed, the sides 108a and 108b of the spool 30 are angled inwardly toward each other, thereby avoiding contact with the flanges 30. The guide arm 16 is also attached to the bracket 14 and rotates about the axis of the spool 12 but independently of the spool 12. The guide arm 16 can be attached to the bracket 14 via one or more fasteners directly 153563.doc 201144202 or anchored to the bracket 14 by the mounting hardware 23. In one embodiment, the studs 29 are disposed on the bracket 14 in a circular array and coupled to the holes or recesses 31 in the guide arms 16 to misalign the guide arms 16 over a range of predefined angles. . The free end of the hose 18 passes through the aperture 20 in the guide arm 16, but is not fully retractable into the spool 12 because of the anchor 22 on the hose 18 (which is too large to fit through the aperture 2). The anchor 22 can be a rubber or plastic barrier that is secured about the hose 18. The guiding arm 16 is composed of two parts: an L-shaped member 32 including one side and a front portion of the guiding arm 16, and an I-shaped member 34 including the opposite side of the guiding arm 16. The L-shaped member 32 and the I-shaped member 34 are fixed together to form the guiding arm 6 as shown. The ratchet element 24 is attached to the spool 12 and engages the pawl 25 on the guide arm 16 to prevent the hose 18 from being improperly retracted. The ratchet element 24 only spans a portion of the radial arc of the spool 12 as shown and thus only a segment of each rotation of the spool 12 is aligned with the pawl 25. When the ratchet member 24 is rotated in the UW direction to be aligned with the pawl 25, the pawl 25 is engaged with the ratchet member 24, and an anti-rotation force that prevents rotation of the spool 12 in the W direction is applied. When the ratchet element 24 is misaligned with the pawl 25 or rotated into the W direction to align with the pawl 25, the pawl 25 does not engage the ratchet element 24 and does not prevent the spool 12 from rotating in either direction. Although the pawl 25 is shown mounted on the guide arm 16 in Fig. 1a, the pawl 25 may be mounted on the bracket 14.卷. Reel 12 Figure 2 includes an axial hub 〇4 (with a cylindrical wall 106 with a hose mount 112), a side wall i 〇 8a (with an outer annular lip n8a) and a side wall i 〇 8b (with outer A front view of the reel 12 of the annular lip 118b and the annular ridge 114) (having a reel half 丨 02 & and 102b). The outer cylindrical wall 1〇6 and the side walls 1〇8& and 1〇815 are bounded together. I53563.doc 201144202 The annular hose holding area 11 〇. As previously stated, the spool 12 is comprised of an axial hub 104 and side walls 108 & and 8 8b. The axial hub 1〇4 includes an inner end wall 12〇 (not visible in Fig. 2; see Fig. 3) and an outer cylindrical wall 106. The outer cylindrical wall 106 is the radially outermost cylindrical portion of the axial hub 1〇4. The side walls 1083 and 108b are annular flanges extending radially from the edges of the outer cylindrical walls 1〇6. Together with the side walls 1〇8a & 1〇8b, the outer cylindrical wall 106 defines a hose retaining area 11〇 (the hose 18 is coiled for storage of one of the annular spaces). In an embodiment, the spool 12 is formed in two halves. The first reel half 102a includes a first side wall 108a and an outer cylindrical wall portion 106a. The second reel half 102b includes a second side wall 10b and an outer cylindrical wall portion 1061. The reel 12 is welded or screwed by the first reel half 2a and the second reel half 1b2b. Formed together. The hose 18 is mounted to the outer cylindrical wall 1 并 6 and at the hose mount 112, the soft mounting member 112 is angled counterclockwise so as not to be excessively bent where the hose 18 is attached to the hose mount 112 Hose 18. In one embodiment, the hose mount 112 is routed through one of the cylindrical walls 1 〇 6 (the hose 18 is threaded through the cylindrical wall 106). In another embodiment, the hose mount 112 is one of the attachment points of the end of the hose 18, and the draw toward the 1/4 further includes attachment means for delivering fluid from a fluid source into the hose 18. In one embodiment, the ratchet member 24 is mounted on a radially opposite side of the spool 12 and the hose mount 112 to avoid locking of the ratchet member 24. When the hose is wound through the hole 20 of the guiding arm 16 onto the reel 2 (see Figures la and lb), the hose is naturally laminated in a pyramid shape and less than the outer cylindrical wall 106 is wider than The four hose widths are generally narrowed as the hoses are stacked radially outward 153563.doc 201144202. Thus the 'outer cylindrical wall 106 is designed to be only slightly larger than four hose widths' because the extra width increases the volume of the hose reel assembly 而 without benefit. The annular ridge 114 extends axially outwardly from the outer cylindrical wall 106 to provide a radially flat surface for attachment of a cover (not shown) of the spool 12. The annular ridge 114 is described in more detail in conjunction with FIG. Extending radially outwardly with the side walls 1 〇 8a and 1 〇 8b, the side walls 10a and 8b are angled inwardly at an oblique angle: the side walls 丨 083 are angled toward the side walls 108b' and vice versa. This beveled construction reinforces the reel 2 without increasing the width of the reel. 3 is a side view of the reel 12 showing the side wall 丨 08b, the annular ridge 114, the mounting hole 116, the outer annular lip 11, the inner end wall 120 having the mounting position 122, and the ratchet member 24. As previously discussed, the axial hub 104 includes an inner end wall 120 and an outer cylindrical wall 1〇6. The inner end wall 120 is a flat radial surface that spans the interior of the spool 12 and is radially inward of the cylindrical wall 106 (see Figure 2). The inner end wall 120 also includes a mounting location 122. The mounting hardware 25 is secured to the mounting location 122 to support the spool 12 on the bracket 14. In one embodiment, the mounting hardware 24 is a shaft or pin' and the mounting location 122 is through one of the inner end walls 120 (the mounting hardware is fitted through the inner end wall 120). Mounting location 122 is described in more detail below. The annular ridge 114 is an area of the side wall 1 〇 8b through which the mounting hole 116 is drilled. The aperture 116 allows a cover (not shown) to be threaded or anchored to the side wall 108b at the annular ridge 114, if so desired. The annular ridge 1 μ is located at one end of the outer cylindrical wall 106 and extends directly radially outward from the outer cylindrical wall 1〇6 to provide a flat mounting surface for the cover. Although the annular ridge 4 is shown on the side 153563.doc • 9- 201144202 108b, the annular ridge 114 may be located on the side 108a. The radially outwardly extending portions of the side walls 108a and 108b are axially outwardly bent into outer annular lips 118a and 118b' which reinforce the spool 12. The second side wall 1 813 terminates in a second outer annular lip 118b' which is axially bent away from the hose retaining region η 〇 and the first side wall 1 〇 8a. Similarly, the first side wall 1 〇 8a (not visible in FIG. 3; see FIG. 2 and 'FIG. 4) terminates in a first outer annular lip 118a that is axially bent away from the soft body holding area 11 and the second side wall. 1〇8b. Because the radially outwardly extending 'side walls 1〇8& and 1〇81' are axially inwardly angled with the side walls 1〇8& and l8b, the outer annular lip 118 does not increase the overall width of the spool 12. . The ratchet element 24 is threaded or riveted to the side walls 1 〇 8b to interact with the pawl 25 as previously discussed. Figure 3 also shows a section line 4-4 which passes through the axis of the spool 12. Figure 4 is an exploded perspective view of one of the spools 12 taken along section line 4-4 of Figure 3. Figure 4 depicts the reel 12' which includes an outer cylindrical wall 1-6, side walls i 〇 8a and i 〇 8b, outer annular lips 118a and 118b, inner end wall sections 120a and 120b and mounting locations 122, collars 124 and Hole 126. Figure 4 shows the reels halves l〇2a and l〇2b for clear decomposition. When the reel I2 is assembled, the reel halves 102 & and 1 〇 21) are attached together as previously discussed. The mounting hardware 25 passes through the mounting location 122 to anchor the spool 12 to the bracket 14. In the embodiment in which the spool 12 is formed by two halves, the inner end wall 丨2〇 can be an abutting section: a first inner end wall section I20a (which is part of the first reel half 102a) And a second inner end wall section i2〇b (which is part of the second reel half 102b). These sections are bolted or welded together to connect the spool half 102a to the spool half 102b. In an embodiment, the first inner end wall section 120a includes an aperture 126 and the second inner end wall section i2〇b includes a shaft 153563.doc 201144202 ring 124. The bore 126 is a central bore of the second inner axial end wall section 12 〇 & and is large enough to accommodate the collar 124. The collar 124 is a central axial extension of one of the second inner axial end wall sections 120b. The portion passes through the aperture 126 and forms a journal of the mounting hardware 25. In another embodiment, the collar 124 is reversing the position of the aperture 126: the collar 124 is located on the first inner end wall section 12A & and the aperture 126 is located in the first inner wall section #also 120b. A bushing or bearing is inserted into the collar 24 to support the spool 12 as the spool 12 rotates. As discussed previously, for increased strength, the sidewalls 108 extend radially outwardly with the sidewalls 108, and the sidewalls 108 are axially inward. tilt. This inward tilting is designed to match the previously mentioned natural pyramid stacking profile of the hose 18 around the inner ring 1 且 6 and thus does not prevent winding. The radially outermost edge of the first side wall 1〇8a terminates in the first outer annular lip 187a, and the radially outermost edge of the second side wall 丨〇8b terminates in the second outer annular lip 11813. The outer annular ridges 118 & and 118 further strengthen the spool 12. Figure 4 also indicates a region R which covers one of the outer cylindrical wall 1〇6 and the second side wall 1〇8b. Figure 5 is an enlarged view of one of the regions R from Figure 4. Figure 5 shows a portion of the inner ring 1 〇 6 and a side wall 10b having an outer annular lip, an annular ridge 114 and a mounting hole 116. The annular ridge 114 is formed by a short distance from the outermost extension of the outer cylindrical wall 1〇6 to the radially outwardly extending side wall 1081 instead of the intersection of the inner annular ring 106b and the side wall 108a to the outer annular lip. 118 & is formed by tilting the side wall l 8b axially inward over the entire radial span. A reel cover can be attached to the side wall by a stud of mounting holes 116. As can be seen in Figure 5, the axial inward tilting of the second side wall 108b prevents the second outer annular lip 丨 18b from increasing the axial volume of the 153563. The same applies to the first side wall 丨〇 8a and the first outer annular lip 118a. This compact design also allows the flange 3 〇 (discussed above with reference to Figure )) to face axially inwardly without contacting the side walls 1〇8& or 1〇8b, thereby further reducing the overall extent of the hose reel 10 Axial volume. Bracket 14 Figure 6 is a plan view of one of the stent mounts 26 of Figure 1 depicting the fastening tab 202, the ridged surface 204, the first side attachment region 2〇6, and the second side attachment region 208. The bracket base 26 is in one embodiment a piece of pressed or cast metal. The bracket side 28a is welded to the appropriate position at the first side attachment area 2〇6. The bracket side 28b is attached to the bracket base 26 at the second side attachment region 208 via a fastener threaded through the fastening tab 2〇2. The fastening tab 202 is stamped by the bracket base 26 in one embodiment and bent at 90 degrees from the base bracket 26 to protrude parallel to the bracket side 28b. In another embodiment, the fastening tab 202 is welded to a separate piece of metal on the bracket base 26. The ridged surface 204 is stamped or cast into the bracket base 26 to reinforce the raised area of the bracket 14 against bending. Figures 7a and 7b are external side and front views, respectively, of the bracket side 28a and the bracket base 26 that are joined to form a l-piece. Figure 3a depicts the bracket base 26 and the bracket side 28a having a flange 30a, a mounting point 21a, a ridge 212a and a stud 29. Figure 3b depicts a bracket base 26 having a ridged surface 204, a fastening tab 202 (having a fastener aperture 214) and a bracket side 28a (having a flange 30a and a stud 29). Mounting hardware 23 is attached to or fed through mounting point 210a to anchor spool 12. If the mounting hardware 23 is, for example, an axle or shaft, the mounting point 110a is a hole through which the mounting hardware 23 passes. As previously described, the flange 30a reinforces the support 153563.doc -12- 201144202 frame 14 and supports the side l 8a. The flange 30a is angled inwardly toward the interior of the hose reel assembly 10 as indicated by the first side attachment region 2〇6 on FIG. The ridge 212a further strengthens the stent side 28a against bending. As shown in Figure 2a, the ridge 212a includes corrugations that extend into the side 28a. The fastening tab 202 has a fastener aperture 214 to permit the threaded fastener to pass through the fastening tab 2〇2 to secure the frame bracket side 28b (see Figures la and lb). The studs 29 help to secure the guide arms 16 to the brackets 14, as described below with reference to Figures i〇a through i〇d. Figure 8 is an external side view of one of the bracket sides 28b depicting a flange 3〇b, a mounting point 21 Ob, a ridge 212b, and a fastener aperture 214b. The flange 3Ob and the ridge 212b strengthen the bracket side 28b like the flange 30a and the ridge 212a reinforcing the bracket side 28a. The mounting hardware 23 is attached or fed through the mounting point 21A, thereby connecting the spool 12 to both sides of the branch 14. The fastener holes 214b in the flange 3Ob allow the bracket side 28b to be mounted on the fastening tab 102. Fasteners 216 (not shown in Fig. 8; see Fig. 9) hold the bracket side 28b in the side attachment area 2〇8 of Fig. 6 through the fastener holes 214 to the fixed frame bracket side 28b to the bracket base 26'. Fasteners 216 can be studs, screws or other threaded fasteners. Figure 9 is a perspective view of one of the brackets 14, including a bracket base 26, bracket sides 28a and 28b (with mounting points 21a and 210b and studs 29, respectively), fastener holes 214, and fasteners 216. As previously discussed, the bracket side 2 is welded to the bracket base 26 to form an L-shaped member. The bracket side 28b is attached to the L-shaped member by inserting fasteners 216 through fastener holes 214a (not visible) and 214b. This configuration simplifies the mounting of the spool 12 (via mounting hardware 23 attached to or fed through the mounting points 210a and 210b). As long as the bracket side 28b is fixed in position, the bracket sides 28a and 28b together lock the spool 12 in place (making the roll 153563.doc -13· 201144202 the drum 12 free to rotate). Mounting or removing the reel 12 is achieved by screwing the fastener 216 from the fastener hole 214, removing the mounting hardware 23 from the mounting point 21 Ob, and disengaging the bracket side 28b from the bracket base 26 and the mounting hardware 23. . The studs 29 interact with the recesses or holes 3 1 (see Figures 1 a and 1 b) to hold the guide arm 6 in position relative to the bracket 14. IV. Guide Arms 16 Figures 10a through 10D illustrate the L-shaped members 32 of the guide arms 16. 1a, 1b, 10c, and 1d are respectively an internal side view, a front view, a top view, and an external side view of the L-shaped member 32. The L-shaped member 32 has a side section 302 (having a ridge 308, an attachment area 310, a pawl mount 402b, a spring mount 404b and a hole 31), a front section 304 (having a front aperture 3 12) and a side tab 306 (with fastener holes 3 1 8). The L-shaped member 32 is attached to the I-shaped member 34 by screwing the fastener 322 (see Fig. 12) through the L-shaped member 32 into the fastener hole 320. Ridge 308 extends the length of side section 302 and strengthens guide arm 16 against bending. As shown in FIG. 1a, the ridge 3〇8 includes corrugations that extend into the side section 302. The guiding arm 16 is attached to the bracket 14 at the attachment area 31〇. In one embodiment, the aperture 31 in the guide arm 16 receives the studs 29 on the bracket 14. The studs 29 and the holes 31 are arranged in a circular array and hold the guide arms 16 in position at any angle within a range of a predetermined angle with respect to the reel 2. When the L-shaped member 32 is attached to the I-shaped member 34, the guiding arm 16 can be rotated about a discrete angular interval of the axis of the spool 12 (defined by the mounting hardware 23) such that the studs 29 are at a desired The guiding arm 16 is supported at the position. In some embodiments, the guide arm 16 can be further supported by either a clamp or a stud fastener, or can be anchored in place by the mounting body 23 of the 153563.doc • 14- 201144202. The hose 18 passes through the front aperture 3 12 and is thus constrained by the guiding arm 16 that is constrained to approach the spool 12 from a limited angular extent. This forces the hose 18 to be wound up in a neat and clean manner on the reel 12 and prevents harmful loads from being applied to the reel 12 or the bracket 14. The pawl 25 (see Figures la and lb) can be attached to the guide arm 16 or bracket 14 to limit rotation of the spool 12. The pawl mount 402b is in one of the mounting positions of the pawl 25, and the spring mount 404b holds the pawl 25 against one of the springs (not shown) of the ratchet member 24, as described in more detail with reference to Figures 13a-15b. The pawl 25 and its interaction with the ratchet element 24. 1 and 1 lb illustrate the I-shaped member 34 of the guiding arm 16. Figure 1 is an external side view of one of the la-shaped I-pieces 34 indicating the line 11 b-11 b. Figure 11b is a cross-sectional view of the I-shaped member 34 taken through the line 11 b-11b. The I-shaped member 34 has a ridge 308, an attachment region 310, a fastener hole 320, a fastener 322, and a hole 31. I-piece 34 is attached to L-piece 32 by fasteners 322 that are secured through fastener holes 318 and 320. In this manner, the L-shaped member 32 and the I-shaped member 34 are joined together to form the guiding arm 14 (which is U-shaped). Like the L-shaped member 32, for increased strength, the I-shaped member 34 is incorporated into the ridge 308 as shown and attached to the bracket 14 at the attachment region 310. As shown in Figure 11a, the ridge 308 includes corrugations that protrude from the I-shaped member 34. The bore 3 1 interacts with the stud 29 to retain the guide arm 16 as described above. The I-shaped member 34 is similar to the side section 304 of the L-shaped member 32, but lacks the side pawl mount 402b and the spring mount 404b present on the side section 304 of the L-shaped member 32.

a perspective view of one of the assembled guide arms 16 showing an L-shaped member 32, an I 153563.doc • 15- 201144202 shaped member 34, an attachment region 310, a fastener aperture 32〇, and a fastener 322. As previously discussed, the guide arms 16 are assembled by securing the members together with the shaped members 34. As with the bracket 14, this configuration simplifies the installation of the spool 12: when the spool 12 is removed or replaced, only the I-shaped member 34 and the (1-shaped) bracket member 28b are required to be detached. Although the bracket 14 and the guide arm 16 have been described as being substantially symmetrical. Shape structure, but it may or may be manufactured. It is an L-shaped asymmetrical portion. In this embodiment, the bracket 14 does not include the bracket side 28b and the guiding arm 16 does not include the I-piece 34. The bracket 14 is attached to the spool 12 and the guide arm 16 only on one side, and thus the mounting hardware 23 must be an asymmetrical pin or cantilever shaft rather than an axle or shaft supported on either side of the spool 12. . This embodiment sacrifices a degree of stent strength to allow the spool 12 to be more easily installed and removed. V. Flash Lock Assembly 400 FIG. 13a is a partial perspective view of the hose reel assembly 1 ,, ignoring the reel 12 and showing the partially removed bracket 14 and the guiding arm 16 ^ the side 28a of the bracket 14 is not shown, Only one portion of the L-shaped member 32 of the guiding arm 16 is shown. Figures 13b and 13c are side views of Figure 13a. Figure 13b shows the pawl 25 mounted on the bracket 14 and Figure 13c shows the pawl 25 mounted on the guiding arm 16. The bracket 14 includes a base 26 and a visible side 28b having a pawl mount 402a and a spring mount 404a. The guide arm 16 includes an attachment location 310 and a visible L-shaped member 32 (having a pawl mount 402b and a spring mount 404b) . The latch assembly 400 includes a spring 408, a stud 410, and a pawl 25 and is attachable to either of the bracket 14 and the guide arm 16. The guide arm 16 is attached to the bracket 14 at the attachment location 310. In an embodiment 153563.doc • 16 · 201144202, the mounting hardware 25 travels through the attachment location 3 1〇 to secure the guiding arm i6 to the bracket 14. In another embodiment, the guide arm 16 is attached to the bracket 14 by one or more pins. As discussed with respect to Figures la and lb, the studs 29 can anchor the guide arms 16 relative to the bracket 14. The latch assembly 14 and the guide arm 16 can be mounted with a latch assembly 4''. The pawl 25 can be mounted to the bracket 14 or to the guide arm 16 by the distribution insertion stud 41 being passed through the pawl 25 into the pawl mount 402a or 402b. The pawl 25 engages the ratchet element 24 as discussed previously to suspend the rotation of the spool 2. The spring 408 is attached to the pawl 25 and the magazine mounting member 4〇4a (if the pawl 25 is mounted to the bracket 14) or the spring mounting member 4〇4b (if the pawl 25 is mounted on the guiding arm 16). Spring mounts 404a and 4〇4b are attachment points for one end of anchor spring 408. In one embodiment, the spring mounts 4〇43 and 4〇4b are stamping tabs formed by the bracket 14 and the guide arm 16 respectively. By stretching between the pawl 25 and the spring mount 404a or 404b, the spring 4A applies a counter-rotating force to the pawl 25 to retain the pawl 25 in engagement with the ratchet member 24, as in Figure 15a. This is further explained in the description of Figure 15b. Although the pawl mounts 4〇2a and 402b are shown on the side 28a and the L-piece 32, respectively, the pawl mounts 402a and 402b can be equally spaced on the side 2 and the tab 34, respectively. However, the attachment positions 4〇2a, 4〇2b, 4〇43, and 4〇 must all lie on the side of the same hose reel assembly 1〇 as the ratchet member 24. Figure 14a is a front elevational view of one of the pawls 25 showing the line 14b-14b. Figure 14b is a cross-sectional view of the pawl 25 of the transmission line 14b-14b. Figure 14 () is a perspective view of a pawl 25 having an exploded sleeve 418. Figures 14a, 14b and 13 illustrate a pawl 25 that includes a sleeve 418 and a pawl body 412 having a pin bore 414, a tip end 415, a spring 153563.doc 17 201144202 spring hole 416 and a recessed six 417. The pawl body 412 is formed from a cast metal in one embodiment. One of the tips 41 5 series body 412 is substantially a triangular tip having a wide edge for retaining the ratchet element 24. To preserve the material and reduce the weight 'not the pawl body 412 is entirely wider than the tip 415; as seen in Figure 14a, the pawl body 412 is flanged with a pocket 417 to reduce the volume of the pawl 25. The tip 41 5 is narrowed. The tip 415 is coupled to the teeth on the ratchet member 24 as discussed with reference to Figures 15a and 15b. The sleeve 418 can be inserted between the stud 410 (see FIGS. 13a and 13b) and the pawl body 412, and the snare body 412 smoothly rotates the β-screw 41 on the spiral 410 through the stud hole 414. (See Figures 14a, 14b, and 14c) to hold the pawl 25 to the pawl mount 402a on the bracket 14 or the pawl mount 4〇2b on the guide arm 16. Spring 408 is attached to pawl 25 at spring aperture 416. The pawl 25 can be mounted on the bracket '14 or on the guide arm 16' as shown in Figures 13b and 13c. 15a and 15b illustrate the pawl 25 that grips the ratchet element 24. Figures 15a and 15b show ratchet element 24, pawl 25 (with pawl body 412 and spring hole 416), spring mount 404, spring 408 and stud 410. Spring mount 404 can be spring mount 404a or spring mounted Pieces 404b. As previously discussed, the studs 410 mount the pawl 25 on the bracket 14 or the guide arm 16. The elastomeric cue 408 is stretched between the spring aperture 416 in the pawl body 412 and the spring mount 4〇4& or 404b. When the pawl body 4丨2 is in contact with the ratchet member 24, the pawl body 412 rotates about the stud 410, and the tension spring 408 causes the spring force to tend to hold the pawl 25 against the ratchet 24. Whether the ratchet pawl 25 engages the ratchet element to prevent rotation in the W direction from depending on the direction in which the ratchet element 24 rotates to align with the pawl. This direction determines that the pawl 25 is angled toward the uw direction (eg, 153563.doc -18·201144202 Figure 15 a) or toward the W direction (Figure 15 b). Figure 15a shows the pawl 25 that has been rotated in the UW direction to align with the ratchet element 24. Accordingly, the pawl 25 will engage the teeth of the ratchet member 24 to prevent the spool 12 from rotating in the W direction as long as the ratchet member 24 remains aligned with the pawl 25. Figure 15b shows the pawl 25 that has been rotated in the W direction to align with the ratchet element 24. In Figure 15b, the teeth of the ratchet element 24 prevent the pawl 25 from catching the ratchet element 24 relative to the pawl. When the pawl 25 engages the ratchet element 24 (Fig. 15a), the pawl 25 can be disengaged by rotating the reel 12 in a direction until the ratchet element 24 is no longer aligned with the pawl 25, so the reel 12 can The freeing direction of the sliding direction seven does not require the pawl 25 to catch the ratchet element 24 (Fig. 15b). This function is the same regardless of whether the pawl 25 is mounted on the bracket 14 or the guiding arm 16. While the soft officer 18 is fully extended from the reel 12, the hose 18 is stretched directly from the hose mount 112 to the hole 2 in the guide arm 16 (see Fig. 2 and Fig. 8). By mounting the ratchet element 24 on the roll The barrel 12 is on the diametrically opposite side of the hose mount 112 (see Figure 2a), thus making it possible to ensure that the ratchet element μ water is not aligned with the guide arm 16 when the soft (four) is fully extended. If the pawl 25 (mounted in the flash lock) At the position of the member 402b, the guide arm 16 is mounted, and the reel 12 can never be flashed into its position due to the absence of the _:un-unlockable position in the e. Therefore, this facilitates the mounting of the pawl to the guide. On the arm 16. However, for some applications, the guide arm may not be used. In this case, the spine 25 may not be attached to the (non-existent) guide arm 16 and must be mounted; on the bracket 14. The reasons described above are for the pawl 25 to be a less desirable position than the guide arm 16, but for the pawl 25 and the bracket 14 is an acceptable alternative position. 153563.doc -19- 201144202 VI. Conclusion The hose reel described herein provides several advantages. The ridge reinforcement on the bracket 14 and the guiding arm 16 is resistant to bending. And providing stability and strength to the inner flange without increasing the hose reel volume. The roll shape of the present invention uses a natural stacking profile of the coiled hose to minimize volume and improve durability without limiting hose movement. The axially inwardly inclined sides of the reel of the hose reel 12 provide increased strength without additional web width and allow the reel 12 to be mounted to the bracket 14 for a tough, compact hose reel assembly. Regardless of the axially inward support of the flange 30. The L-shaped member and the 1-piece construction bracket 14 and the guide arm 16 simplify the assembly of the hose reel 1 并 and allow easy access to the reel 12. The reel 12 can The fasteners 322 and 216 are respectively screwed from the guiding arm 16 and the bracket 14 and the mounting hardware 23 is disconnected from the mounting point 310. The I-shaped member 34 and the bracket side 28b can then be removed, allowing The reel 12 is detached from the fastening hardware 23. The mounting reel 12 follows the reverse procedure: first the reel 12 is attached to the fastening hardware 23, and then the bracket side 28b and the final piece 34 are secured by fasteners 216 and 322, respectively. In the proper position on the base 26 and the L-shaped member 32. By both the guiding arm 16 and the bracket 14 Providing an attachment point for the pawl 25 and the spring 408, the present invention allows the hose reel 1 〇 to be used with or without the guide arm 16 while enabling optimal latch placement for either situation. Attached to the guide arm 16 or bracket 14, the latch assembly 40 is identically manufactured - the user can remove the stud 410 from the pawl mount 4a 2a or 402b and disassemble the spring 408 from the spring mount 404a or 404b The present invention is described with reference to one (several) illustrative embodiment, but the reference to one (several) exemplary embodiment has been described, however, from the bracket 14 to the guide arm 16 for quick and easy exchange of the latch assembly 4 〇〇 or vice versa. Those skilled in the art will recognize that various changes can be made without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention.
