Abstract
Description
本發明與手工具有關,尤指一種刮刀。The present invention relates to hand tools, especially a scraper.
在裝潢工作場合中,常常需要使用刮刀來刮除黏附於牆面或地板的粘膠、油漆或其它異物,例如台灣公告I345021、M448536、M421356、中國公告號CN204634718U、CN201471403U及美國公開號 US20090320299A1等專利。儘管目前已有多款刮刀推出市面以供選購,然而,對於使用需求日增的廣大使用者而,現有刮刀仍不敷使用,因此,如何提供新式刮刀設計,乃為業界所引頸企盼者。In decoration workplaces, it is often necessary to use a scraper to scrape off glue, paint or other foreign matter adhering to the wall or floor, such as Taiwan Bulletin I345021, M448536, M421356, China Bulletin No. CN204634718U, CN201471403U and US Publication No. US20090320299A1 and other patents . Although a variety of scrapers have been launched on the market for purchase, the existing scrapers are still insufficient for the vast number of users with increasing demand. Therefore, how to provide a new scraper design has been eagerly anticipated by the industry.
為提供使用者更多的使用選擇,本發明提供一種新的刮刀,其包括一刀柄、由一第一金屬製成的一刀體、及由一第二金屬製成的一刀頭。更詳而言之,該刀柄具有一前段、一中段及一後段。該刀體具有一前端及一後端,且該刀體的該後端固定於該刀柄的該前段內。該刀頭的一後側面連接該刀體,且該刀頭的硬度大於該刀體,其中,該刀頭的一前側面垂直於該刀頭的一下側面。In order to provide users with more choices, the present invention provides a new scraper, which includes a handle, a body made of a first metal, and a head made of a second metal. More specifically, the handle has a front section, a middle section and a rear section. The cutter body has a front end and a rear end, and the rear end of the cutter body is fixed in the front section of the handle. A rear side surface of the cutter head is connected to the cutter body, and the hardness of the cutter head is greater than that of the cutter body, wherein a front side surface of the cutter head is perpendicular to a lower side surface of the cutter head.
在一實施例中,本發明上述刮刀的該刀頭的該前側面係為一凸弧面。In one embodiment, the front side surface of the cutter head of the scraper of the present invention is a convex arc surface.
在一實施例中,本發明上述刮刀的該刀頭具有沿著寬度間隔排列的多個凹槽,每一凹槽係從該刀頭的一上側面往下凹且由該刀頭的該前側面向後貫通至該刀頭的該後側面,以致於每兩凹槽之間形成一齒。In one embodiment, the cutter head of the scraper of the present invention has a plurality of grooves arranged at intervals along the width, and each groove is concave downward from an upper side of the cutter head and extends from the front of the cutter head. The flank penetrates backward to the rear flank of the cutter head, so that a tooth is formed between every two grooves.
在一實施例中,本發明上述刮刀的刀頭的該前側面係為一凸弧面。In one embodiment, the front side surface of the cutter head of the scraper of the present invention is a convex arc surface.
在一實施例中,本發明上述刮刀的該刀柄的該中段具有相背對的一上側弧面及一下側弧面,該刀柄的該後段足以讓一使用者的手握持,該上側弧面足以讓該使用者的姆指抵壓,該下側弧面足以讓該使用者的食指勾靠。In one embodiment, the middle section of the handle of the scraper of the present invention has an upper side arc surface and a lower side arc surface opposite to each other, the rear section of the handle is sufficient for a user's hand to hold, the upper side arc The arc surface is enough for the user's thumb to press, and the lower arc surface is enough for the user's index finger to hook.
在一實施例中,本發明上述刮刀的該刀柄的該中段具有相背對的一左側弧面及一右側弧面,該左側弧面足以讓該使用者的姆指抵壓,該右側弧面足以讓該使用者的食指勾靠。In one embodiment, the middle section of the handle of the scraper of the present invention has a left arc surface and a right arc surface opposite to each other, the left arc surface is sufficient for the user's thumb to press against, and the right arc The surface is large enough for the user's index finger to hook.
在一實施例中,本發明上述刮刀的該刀頭由鎢鋼製成。In one embodiment, the cutter head of the scraper of the present invention is made of tungsten steel.
在一實施例中,本發明上述刮刀的該刀頭是一體形成的一矩形塊體或一梯形塊體。In one embodiment, the cutter head of the scraper of the present invention is a rectangular block or a trapezoidal block integrally formed.
在一實施例中,本發明上述刮刀的該刀頭的寬度及厚度均大於該刀體,該刀頭的長度小於該刀體。In one embodiment, the width and thickness of the cutter head of the scraper of the present invention are larger than the cutter body, and the length of the cutter head is smaller than the cutter body.
圖1至3顯示之刮刀1為本發明的一第一較佳實施例,其包括一刀柄11、一刀體12及一刀頭13。該刀柄11具有一前段110、一中段111及一後段112。該刀體12的一後端121固定於該刀柄11的該前段110內,該刀體12材質由一第一金屬製成,例如由鐵製成,較佳可選擇鑄鐵。該刀頭13材質由一第二金屬製成,例如由鋼製成,較佳可選擇鎢鋼。無論如何,在材質選擇上,用來製作刀頭13的該第二金屬硬度應大於用來製作刀體12的該第一金屬。再者,該刀頭13的一後側面131連接該刀體12的一前端120、該刀頭13的一前側面130垂直於該刀頭13的一下側面132。較佳地,刀頭13的寬度W(例如約21mm至22mm)大於該刀體12的寬度W1(例如約19mm至20mm)、該刀頭13的厚度T(例如約4mm至5mm)大於該刀體12的厚度T1(例如約3mm至4mm)及該刀頭13的長度L(例如約3mm至4mm)小於該刀體12的長度L1(例如約44mm至50mm)。此外,該刀頭13較佳是一體形成的一矩形塊體或一梯形塊體。The scraper 1 shown in FIGS. 1 to 3 is a first preferred embodiment of the present invention, which includes a
在此實施例中,該刀頭13的該後側面131與該刀體12的該前端120以焊接方式形成連接,但不以此為限。In this embodiment, the
圖4顯示一使用者手持本發明之刮刀去刮除形成在一汽車鈑金金屬3上的一塊待刮除物2的動作,在該使用者依箭頭A所示的施力方向推動該刮刀1時,如圖3及圖4所示,位於該刀頭13的該前側面130與該下側面132的垂直相交之處的一刃緣134,就可將待刮除物2予以破壞並刮除。待刮除物2可為油漆、污漬、殘膠、堅硬且牢附於鈑金表面的汽車烤漆或頑固的鏽層等異物。4 shows the action of a user holding the scraper of the present invention to scrape off a piece of object to be scraped 2 formed on a
圖5及圖6顯示之刮刀1a為本發明的一第二較佳實施例,其大致相同於上述刮刀1,不同之處在於以另一刀頭13a取代上述的刀頭13。該刀頭13a的一前側面130a係為一凸弧面,以致於該刀頭13a的一刃緣134a呈一弧形。藉由呈弧形的該刃緣134a,如圖7所示,該刀頭13a與該待刮除物2的接觸面積將大幅縮小(相對於上述第一較佳實施例中的刮刀1而言),如此,刮刀1a推刮待刮除物2時所受的阻力將變小而較為省力,同時,刮刀1a推刮待刮除物2的力道也會較為集中而較易破壞待刮除物2,這意味著該使用者使用該刮刀1a推刮待刮除物2時將較為省力、順𣈱。The
圖8及圖9所顯示之刮刀1b為本發明的一第三較佳實施例,其大致相同於上述刮刀1,不同之處在於以另一刀頭13b取代上述的刀頭13。進一言之,該刀頭13b具有沿著其寬度W2間隔排列的多個凹槽g,每一凹槽g係從該刀頭13b的一上側面133b往下凹且由一前側面130b向後貫通至一後側面131b,以致於每兩凹槽g之間形成一齒t。如圖10所示,該使用者可先利用該刮刀1b的該些齒t在待刮除物2上向後刮,藉以刮劃出彼此相間的多道刮痕21及多道待刮殘餘22,接著,再如圖11所示,將刮刀1b翻面後,向前推刮待刮除物2的該些待刮殘餘22。依此方式,就可分兩次將同一區域內的待刮除物2刮除,亦即,第一次刮(例如向後刮),是先刮掉一些待刮除物2(即原先佔據該些刮痕21的待刮除物2),第二次刮(例如向前刮),則刮掉另一些待刮除物2(即該些待刮殘餘22)。因此,該使用者使用該刮刀1b去刮同一區域內的待刮除物2時,就會感到較為輕鬆、省力(相對於上述第一較佳實施例中的刮刀1而言)。The
圖12及圖13顯示之刮刀1c為本發明的一第四較佳實施例,其大致相同於上述刮刀1b,不同之處在於以另一刀頭13c取代上述的刀頭13b,該刀頭13c的一前側面130c係為一凸弧面,簡言之,該刀頭13c是上述刀頭13b及刀頭13a的整合結果,從而兼具它們的上述功效,容不贅述。The
再者,如圖1、4所示,本發明之上述刮刀1~1c均選用相同的刀柄11,但不以此為限。無論如何,該刀柄11的該後段112係足以讓該使用者的手握持,該刀柄11的中段111具有相背對的一上側凹弧面140及一下側凹弧面141,該上側弧面140足以讓該使用者的姆指抵壓,該下側弧面141足以讓該使用者的食指勾靠。較佳地,該中段111還具有相背對的一左側凹弧面142及一右側凹弧面143,當該使用者以如圖14所示的姿勢握持上述刮刀1~1c任一者時,該左側凹弧面142足以讓該使用者的姆指抵壓,該右側凹弧面143則足以讓該使用者的食指勾靠。無論該使用者採取圖4或14所示的姿勢,藉由上述上側凹弧面140及下側凹弧面141(或該左側凹弧面142及該右側凹弧面143),使他在進行上述刮除動作時,不但能穩定施力而有助於待刮除物2的刮除,也不易滑脫而能降低因手滑而碰觸到周遭銳利物品而受傷的機率。Furthermore, as shown in FIGS. 1 and 4 , the scrapers 1 to 1 c of the present invention all use the
