具有刹車裝置的嬰兒學步車 Baby walker with brakes
本發明提供一種具有刹車裝置的嬰兒學步車,其適用於未滿一周歲(或未滿二周歲)的嬰兒。是為防止嬰兒在騎著學步車遇到門檻或臺階時摔倒或墜落的發明。以下,參考圖式,對具有刹車裝置的嬰兒學步車進行詳細的說明。 The present invention provides a baby walker with a brake device that is suitable for infants under one year old (or less than two years old). It is an invention to prevent the baby from falling or falling when riding a walker on a threshold or step. Hereinafter, a baby walker having a brake device will be described in detail with reference to the drawings.
如圖1所示,嬰兒學步車10大略分為上部座椅部、下部框架200、腳輪300和支撐框架400。由於上述的各種結構元件與習知技術中熟知的構成要素相同,在這裡就不加以詳細的說明。在不影響本發明 的技術思想的情況下,將作為引用。首先,上部座椅部分為收容嬰兒的座椅部120和上部框架110。上部座椅部在下部框架200的上方,高度應該能讓坐在座椅部120的嬰兒的雙腳踩到地面。上部框架110可以外加音樂、玩具等娛樂設備。 As shown in FIG. 1, the baby walker 10 is roughly divided into an upper seat portion, a lower frame 200, casters 300, and a support frame 400. Since the various structural elements described above are the same as those well known in the prior art, they will not be described in detail herein. Without affecting the invention The case of technical ideas will be used as a reference. First, the upper seat portion is a seat portion 120 and an upper frame 110 that accommodate the infant. The upper seat portion is above the lower frame 200 at a height that allows the infant's feet sitting on the seat portion 120 to step on the ground. The upper frame 110 can be supplemented with entertainment equipment such as music and toys.
如圖1所示,下部框架200固定在腳輪300上;上部座椅部與下部框架200被固定在支撐框架400的上下方;支撐框架400以交叉方式支撐著上部座椅部和下部框架200。下部框架200的直徑要比上部框架110大,並且要做成類似正方形或長方形。在不影響本發明技術思想的條件下,可以任意選擇上部框架110、下部框架200和支撐框架400的材料和形狀。下部框架200的下方具有防止嬰兒學步車翻車或墜落的刹車裝置,將參照圖2和圖5加以說明。 As shown in FIG. 1, the lower frame 200 is fixed to the caster 300; the upper seat portion and the lower frame 200 are fixed to the upper and lower sides of the support frame 400; and the support frame 400 supports the upper seat portion and the lower frame 200 in an intersecting manner. The lower frame 200 has a larger diameter than the upper frame 110 and is made to resemble a square or a rectangle. The materials and shapes of the upper frame 110, the lower frame 200, and the support frame 400 can be arbitrarily selected without affecting the technical idea of the present invention. Below the lower frame 200, there is a brake device for preventing the baby walker from rolling over or falling, which will be described with reference to Figs. 2 and 5.
圖1的下部框架200的底部組合了4個腳輪300,且實現方式說明如下。如圖2所示,前述4個腳輪的第一腳輪310在左側上端;前述4個腳輪的第二腳輪320在右側上端;前述4個腳輪的第三腳輪330在左側下端;前述4個腳輪的第四腳輪340位於右側下端。顯而易見,左右、上下的定義會根據不同的基準點而發生變化。在這裡,雖然圖2的腳輪310、320、330與340只有4個,但是我們可以根據情況減少或增加其數量。 The bottom of the lower frame 200 of Fig. 1 incorporates four casters 300, and the implementation is described below. As shown in FIG. 2, the first casters 310 of the four casters are at the upper left end; the second casters 320 of the four casters are at the upper right end; the third casters 330 of the four casters are at the lower left end; the four casters are The fourth caster 340 is located at the lower right end. Obviously, the definitions of left and right, up and down will change according to different benchmarks. Here, although there are only four casters 310, 320, 330, and 340 of FIG. 2, we can reduce or increase the number according to the situation.
在每個腳輪310、320、330與340的附近分別設置了具有一定長度和寬度的框架刹車裝置211~218。即,第一腳輪310的附近有第一及第五框架刹車裝置211、215;第二腳輪320的附近有第二及第七框架刹車裝置212、217;第三腳輪330的附近有第三及第六框架刹車裝置213、216;第四腳輪340的附近有第四及第八框架刹車裝置214、218。 如圖2所示,第一至第四框架刹車裝置211、212、213、214設置在水平方向,而第五至第八框架刹車裝置215、216、217、218設置在垂直方向。 Frame brake devices 211 to 218 having a certain length and width are respectively disposed in the vicinity of each of the casters 310, 320, 330, and 340. That is, the first caster 310 has first and fifth frame brake devices 211, 215; the second caster 320 has second and seventh frame brake devices 212, 217; the third caster 330 has a third and adjacent The sixth frame brake devices 213, 216; the fourth and eighth frame brake devices 214, 218 are adjacent to the fourth caster 340. As shown in FIG. 2, the first to fourth frame brake devices 211, 212, 213, 214 are disposed in the horizontal direction, and the fifth to eighth frame brake devices 215, 216, 217, 218 are disposed in the vertical direction.
防止嬰兒學步車在向前後方向行進時的摔倒和墜落 Prevents the baby walker from falling and falling when moving in the forward and backward directions
如圖2所示,假設嬰兒學步車向前方行進。當第一及第三腳輪310、330要越過門檻或傾斜面的邊緣時,第一及第三框架刹車裝置211、213與地表面緊密接觸(因摩擦力或附著力),使得嬰兒學步車不再前進,從而起到防止嬰兒學步車翻車或墜落的效果。 As shown in Fig. 2, it is assumed that the baby walker travels forward. When the first and third casters 310, 330 are to pass over the edge of the sill or inclined surface, the first and third frame brake devices 211, 213 are in close contact with the ground surface (by friction or adhesion), so that the baby walker No longer moving forward, thus preventing the baby walker from rolling over or falling.
此外,假設嬰兒學步車向後方行進。當第二及第四腳輪320、340遇到門檻或行進到斜坡的邊緣時,第二及第四框架刹車裝置212、214與地表面緊密接觸(因摩擦力或附著力),使得嬰兒學步車不再前進,從而起到防止嬰兒學步車翻車或墜落的效果。上述的向前或向後方向的前進可包括以一定的角度(0~90度)前進。 In addition, assume that the baby walker travels backwards. When the second and fourth casters 320, 340 encounter the threshold or travel to the edge of the ramp, the second and fourth frame brakes 212, 214 are in intimate contact with the ground surface (due to friction or adhesion), allowing the baby to walk The car no longer moves forward, thus preventing the baby walker from rolling over or falling. The advancement of the forward or backward direction described above may include advancing at a certain angle (0 to 90 degrees).
防止嬰兒學步車在向著側方向行進時的摔倒和墜落 Prevent the baby walker from falling and falling while heading sideways
如圖2所示,根據本發明的實施方案,腳輪310、320、330與340可以全方向轉動。即,如圖2中所示,當嬰兒利用自己的雙腳移動嬰兒學步車時,可以向前、向後,還可以如圖3所示向側方移動。這時,側方移動可包括以一定的角度0~90度前進。 As shown in FIG. 2, casters 310, 320, 330, and 340 can be rotated in all directions in accordance with an embodiment of the present invention. That is, as shown in FIG. 2, when the infant moves the baby walker with his or her feet, it can move forward and backward, and can also move sideways as shown in FIG. At this time, the lateral movement may include advancing at an angle of 0 to 90 degrees.
如圖3所示,當嬰兒學步車在向側方向行進時,單靠位於垂直方向的第五至第八框架刹車裝置215、216、217、218並不能完全地防止嬰兒學步車在階梯前的翻車、墜落等事故。為此,發明人經過了一系列的實驗發現可以利用如圖3所示的內側刹車裝置221、222來解決上述問題。即,根據本發明的實施方案要把內側刹車裝置221、222彼此相對 設置在下部框架200的內側邊緣。因此,第一至第八框架刹車裝置211~218應水平或垂直的設置在下部框架200的下表面;內側刹車裝置221、222應連接到下部框架200的內邊緣的頂部。這時,下部框架200的內邊緣表面在接近下部框架200的中心的表面上,且下部框架200的外邊緣表面被假定為遠離下部框架的中心。作為內側刹車裝置221、222的一個例子,如圖3所示,第一內側刹車裝置221位於第一腳輪310和第二腳輪320之間且位於下部框架200的內邊緣的頂部。第二內側刹車裝置222也設置內邊緣,以在第三腳輪330和第四腳輪340之間與第一內側刹車裝置221彼此對應。以嬰兒學步車為標準假設一個垂直虛線30,那麼第一及第二內側刹車裝置221、222應當設置在這條虛線上。垂直虛線平分嬰兒學步車,在第一及第二內側刹車裝置221、222的中心點上。第一及第二內側刹車裝置221、222在中心點的橫向兩側。此外,以設置在上端兩邊的第一及第二腳輪310、320為準假設水平虛線20,第一內側刹車裝置221應當設置在這條虛線20的後方。即,第一內側刹車裝置221應當設置在第一及第二腳輪310、320的後方。如若不然,將起不到刹車裝置原本的作用。 與第一內側刹車裝置相同,第二刹車裝置222應當設置在第三及第四腳輪330、340之水平線的後方。如圖3所示,第一內側刹車裝置221是為了防止嬰兒學步車向著側面行進時的事故,而第二內側刹車裝置222是為了防止反方向的事故。 As shown in FIG. 3, when the baby walker is traveling in the side direction, the fifth to eighth frame brake devices 215, 216, 217, 218 located in the vertical direction alone cannot completely prevent the baby walker from being stepped on the ladder. The previous rollover, falling and other accidents. To this end, the inventors have conducted a series of experiments and found that the inner brake devices 221, 222 shown in Fig. 3 can be used to solve the above problems. That is, the inner brake devices 221, 222 are opposed to each other according to an embodiment of the present invention. It is disposed at the inner side edge of the lower frame 200. Therefore, the first to eighth frame brake devices 211 to 218 should be disposed horizontally or vertically on the lower surface of the lower frame 200; the inner brake devices 221, 222 should be connected to the top of the inner edge of the lower frame 200. At this time, the inner edge surface of the lower frame 200 is on the surface close to the center of the lower frame 200, and the outer edge surface of the lower frame 200 is assumed to be away from the center of the lower frame. As an example of the inner brake devices 221, 222, as shown in FIG. 3, the first inner brake device 221 is located between the first caster 310 and the second caster 320 and is located at the top of the inner edge of the lower frame 200. The second inner brake device 222 is also provided with an inner edge to correspond to the first inner brake device 221 between the third caster 330 and the fourth caster 340. A vertical dashed line 30 is assumed on the basis of the baby walker, and the first and second inner brake devices 221, 222 should be placed on this dotted line. The vertical dashed line divides the baby walker at the center of the first and second inner brakes 221, 222. The first and second inner brake devices 221, 222 are on both lateral sides of the center point. Further, the first inner and second casters 310 and 320 disposed on both sides of the upper end are assumed to be horizontal dashed lines 20, and the first inner brake device 221 should be disposed behind the broken line 20. That is, the first inner brake device 221 should be disposed behind the first and second casters 310, 320. If not, the original function of the brake device will not be achieved. Like the first inner brake device, the second brake device 222 should be disposed behind the horizontal lines of the third and fourth casters 330, 340. As shown in FIG. 3, the first inner brake device 221 is for preventing an accident when the baby walker travels toward the side, and the second inner brake device 222 is for preventing an accident in the opposite direction.
上述的水平虛線20隨著腳輪310、320、330與340的位置而改變,也就是說內側刹車裝置221、222的位置是隨著腳輪310、320、330與340的位置而變化的。 The horizontal dashed line 20 described above changes with the position of the casters 310, 320, 330 and 340, that is, the position of the inner brakes 221, 222 varies with the position of the casters 310, 320, 330 and 340.
另一方面,在圖3中,雖然各自只有一個第一及第二內側刹車裝置221、222,但是可根據需要在上端和下端的內側邊緣設置複數個內側刹車裝置。 On the other hand, in Fig. 3, although there is only one first and second inner side brake devices 221, 222, a plurality of inner side brake devices may be provided at the inner side edges of the upper end and the lower end as needed.
作為內側刹車裝置221、222的另外一個例子,如圖4所示,第一內側刹車裝置221應當設置在第一腳輪310和第二腳輪320之間靠近下部框架200的內邊緣頂部,而第二內側刹車裝置222應當設置在第三及第四腳輪330、340之間與第一內側刹車裝置221相對應。第一及第二內側刹車裝置221、222應在垂直虛線30的右側或左側(可以如圖4所示設置在虛線的右側,還可以設置在虛線的左側)。即,第一及第二內側刹車裝置221、222應當設置在垂直虛線的左右兩側。垂直虛線是平分嬰兒學步車的虛擬線,不應當把內側刹車裝置221、222設置在這條線上。第一及第二內側刹車裝置221、222要設置在各自中心點的左右兩側。再者,第一內側刹車裝置221要設置在第一及第二腳輪310、320的水平線20的後方。即,第一內側刹車裝置221要設置在第一及第二腳輪310、320的後方。如果把第一內側刹車裝置221設置在第一及第二腳輪310、320的水平線的前方或水平線上則不能防止事故的發生。與第一內側刹車裝置221相同,第二內側刹車裝置222也應當設置在第三及第四腳輪330、340的水平線的後方。即,第二內側刹車裝置222應該設置在第三及第四腳輪330、340的後方。因此,如圖3所示,第一內側刹車裝置221可防止嬰兒學步車在向著側方向行進時遇到臺階時的翻車事故,而第二內側刹車裝置222則能防止與圖相反方向的事故。此時,如圖4所示,第二及四框架刹車裝置212、214有可能不存在。 As another example of the inner brake devices 221, 222, as shown in FIG. 4, the first inner brake device 221 should be disposed between the first caster 310 and the second caster 320 near the top of the inner edge of the lower frame 200, and the second The inner brake device 222 should be disposed between the third and fourth casters 330, 340 corresponding to the first inner brake device 221. The first and second inner brake devices 221, 222 should be on the right or left side of the vertical dashed line 30 (may be disposed on the right side of the dashed line as shown in FIG. 4, and may also be disposed on the left side of the broken line). That is, the first and second inner brake devices 221, 222 should be disposed on the left and right sides of the vertical dashed line. The vertical dashed line is the virtual line that bisects the baby walker, and the inner brakes 221, 222 should not be placed on this line. The first and second inner brake devices 221, 222 are disposed on the left and right sides of the respective center points. Furthermore, the first inner brake device 221 is disposed behind the horizontal line 20 of the first and second casters 310, 320. That is, the first inner brake device 221 is to be disposed behind the first and second casters 310, 320. If the first inner brake device 221 is disposed in front of the horizontal line of the first and second casters 310, 320 or on the horizontal line, the occurrence of an accident cannot be prevented. Like the first inner brake device 221, the second inner brake device 222 should also be disposed behind the horizontal lines of the third and fourth casters 330, 340. That is, the second inner brake device 222 should be disposed behind the third and fourth casters 330, 340. Therefore, as shown in FIG. 3, the first inner brake device 221 can prevent a rollover accident when the baby walker encounters a step when traveling in the side direction, and the second inner brake device 222 can prevent an accident in the opposite direction to the figure. . At this time, as shown in FIG. 4, the second and fourth frame brake devices 212, 214 may not exist.
刹車部件 Brake unit
如圖2及圖3所示,框架刹車裝置211~218與內側刹車裝置221、222可以由如圖5所示的一個刹車部件230實現。刹車部件230的上端設有由橡皮製成的緊閉部231,緊閉部231下端有決定下端刹車部件230高度的高度部232。當嬰兒學步車行進到臺階或門檻時,緊閉部231會與地面發生摩擦停止嬰兒學步車的前進;緊閉部231可以用橡皮製成。此外,如圖2及圖3所示,緊閉部231可以製成波浪性等凹凸不平的形狀,使得能更好的抓住地面。高度部232是用來設定刹車部件230高度的部件;高度部232可以用類似塑膠的材料製成。 As shown in FIGS. 2 and 3, the frame brake devices 211 to 218 and the inner brake devices 221 and 222 can be realized by a brake member 230 as shown in FIG. The upper end of the brake member 230 is provided with a closing portion 231 made of rubber, and the lower end of the closing portion 231 has a height portion 232 that determines the height of the lower end brake member 230. When the baby walker travels to the step or threshold, the tight portion 231 rubs against the ground to stop the advancement of the baby walker; the tight portion 231 can be made of rubber. Further, as shown in FIGS. 2 and 3, the closed portion 231 can be formed into a rugged shape such as a wave, so that the ground can be better grasped. The height portion 232 is a member for setting the height of the brake member 230; the height portion 232 may be made of a material similar to plastic.
刹車部件230的高度H隨著腳輪310、320、330與340的高度而改變。如果腳輪310、320、330與340的高度偏高,則為了增加與地面的摩擦而提高刹車裝置230的高度。再者,長度L隨嬰兒學步車下部框架200的長寬而改變。框架刹車裝置211~218與內側刹車裝置221、222可以相同大小製成,也可以根據需求製成不同的大小。刹車部件230的長、寬、高大約為14cm、3.2cm、4cm。不過,如上所述,可根據腳輪的高度,嬰兒學步車的下端框架的長寬來調整此數值。 The height H of the brake member 230 changes with the height of the casters 310, 320, 330, and 340. If the heights of the casters 310, 320, 330, and 340 are relatively high, the height of the brake device 230 is increased in order to increase friction with the ground. Furthermore, the length L varies with the length and width of the baby walker lower frame 200. The frame brake devices 211 to 218 and the inner brake devices 221 and 222 can be made of the same size or can be made to have different sizes as required. The length, width, and height of the brake member 230 are approximately 14 cm, 3.2 cm, and 4 cm. However, as described above, this value can be adjusted depending on the height of the caster and the length and width of the lower end frame of the baby walker.
此外,如圖3及圖4所示,內側刹車裝置221應當設置在距離上部框架110的d處的內側邊緣。此時,d大約為20~30cm。 Further, as shown in FIGS. 3 and 4, the inner brake device 221 should be disposed at an inner edge from the d of the upper frame 110. At this time, d is approximately 20 to 30 cm.
根據本發明的一個實施方案,刹車部件230的高度部232內側如圖6所示具有第一支撐部233a、第二支撐部233b、第三支撐部233c、第一位置固定部234a、第二位置固定部234b、第三位置固定部234c。第一至第三支撐部233a、233b、233c位於高度部232的下方切面以圓形向 外突出;第一至第三支撐部233a、233b、233c可用塑膠等材料製成。第一至第三支撐部233a、233b、233c與下端框架200上的3個開孔連接。連接時要與第一及第三支撐部233a、233c之間有間隙,使得與第二支撐部233b之間緊密相接沒有間隙。再者,當第一至第三支撐部233a、233b、233c插入開孔時設定其高度,預備有第一及第三位置固定部234a、234b、234c。即,在插入第一至第三支撐部233a、233b、233c時,第二支撐部233b要比第一及第三支撐部233a、233c高出,第一支撐部233a與第三支撐部233c的高度要相同。第二支撐部233b要無間隙,而第一及第三支撐部233a、233c要有間隙,第二支撐部233b的高度則要比其它的高出,使得刹車部件230以第二支撐部233b為軸形成蹺蹺板,提高與地面的摩擦力。 According to an embodiment of the present invention, the inside of the height portion 232 of the brake member 230 has a first support portion 233a, a second support portion 233b, a third support portion 233c, a first position fixing portion 234a, and a second position as shown in FIG. The fixing portion 234b and the third position fixing portion 234c. The first to third support portions 233a, 233b, 233c are located at a lower cut surface of the height portion 232 in a circular direction The outer protrusions; the first to third support portions 233a, 233b, 233c may be made of a material such as plastic. The first to third support portions 233a, 233b, 233c are connected to the three openings on the lower end frame 200. There is a gap between the first and third support portions 233a, 233c when connected, so that there is no gap between the second support portion 233b and the second support portion 233b. Further, when the first to third support portions 233a, 233b, and 233c are inserted into the opening, the height thereof is set, and the first and third position fixing portions 234a, 234b, and 234c are prepared. That is, when the first to third support portions 233a, 233b, 233c are inserted, the second support portion 233b is higher than the first and third support portions 233a, 233c, and the first support portion 233a and the third support portion 233c The height must be the same. The second support portion 233b has no gap, and the first and third support portions 233a, 233c have a gap, and the height of the second support portion 233b is higher than the others, so that the brake member 230 is the second support portion 233b. The shaft forms a seesaw that increases the friction with the ground.
第一至第三支撐部233a、233b、233c位於高度部232的內側縱向方向上,且大概各自的位於中央處。第一至第三位置固定部234a、234b、234c大略以長方形的形狀位於第一至第三支撐部233a、233b、233c的兩側。這時,支撐部233要比位置固定部234高出,特別是第二位置固定部234b要比第一及第三位置固定部234a、234c凸出,使得插入時第二支撐部233b更高。 The first to third support portions 233a, 233b, 233c are located in the inner longitudinal direction of the height portion 232, and are approximately located at the center. The first to third position fixing portions 234a, 234b, and 234c are located substantially in a rectangular shape on both sides of the first to third support portions 233a, 233b, and 233c. At this time, the support portion 233 is higher than the position fixing portion 234, and in particular, the second position fixing portion 234b is protruded from the first and third position fixing portions 234a, 234c so that the second support portion 233b is higher at the time of insertion.
雖然圖面上未標明,但是上述的刹車部件230可以用按壓的方式來調整其高度。尤其是內側刹車裝置可以向著豎直方向折疊90度。可以藉由按壓和折疊的方法防止附件過於緊貼地面,並保持其優雅的外觀。 Although not shown on the drawing, the above-described brake member 230 can be adjusted in height by pressing. In particular, the inner brake can be folded 90 degrees in the vertical direction. The attachment can be prevented from being too close to the ground by pressing and folding, and maintaining its elegant appearance.
另外,還可以在嬰兒學步車設置傾斜感測器;當嬰兒學步車傾斜時由感測器來接收資料來控制其按壓和折疊。 In addition, a tilt sensor can also be provided in the baby walker; when the baby walker is tilted, the sensor receives the data to control its pressing and folding.
