Description

本発明は使用しない際に折り畳んで自立できるペットカートに関する。   The present invention relates to a pet cart that can be folded and self-supported when not in use.

これまでに折り畳んだ際に自立できるベビーカーは存在した（特許文献１）。
しかし、ペットカートはペットを乗せる収容部（バケット部）がベビーカーのシート部に比較して広く、折り畳んだ際の収容部がかさ高になり、自立が不安定になりやすかった。
特許文献１は自立させた際にベビーカーの重心がスタンド部の支持部に位置するように設定した旨の記載があり、そのままペットカートに適用できるものではない。 There has been a stroller that can be self-supported when folded (Patent Document 1).
However, in the pet cart, the accommodating portion (bucket portion) on which the pet is placed is wider than the seat portion of the stroller, the accommodating portion when folded is bulky, and the independence tends to be unstable.
Patent Document 1 has a description that the center of gravity of the stroller is set so as to be positioned at the support portion of the stand portion when it is self-supporting, and is not applicable to a pet cart as it is.

特許第４１４４７８６号公報Japanese Patent No. 4144786

本明細書では、ペットカートの進行方向を前方と表現し、進行方向と直交する方向を左右方向と表現する。
ペットカートはフレーム車体構造を有し、このフレームに犬等のペットを収容するバケット部を取り付けたものである。
フレーム構造からなる左右の前脚部と左右の後脚部とを離間又は近接方向に移動する構造としては、例えば２本のフレームをクロスさせたＸフレーム構造を採用することができ、前脚部の前輪を持ち上げるように折り畳む構造としては、手押しするハンドルフレームと前脚部を構成するフレームとを屈曲自在に連結し、後脚部を構成するフレームの上端をハンドルフレームの途中に回動自在に連結するフレーム構造例等が挙げられる。
なお、本発明は左右後脚部が相互に近接する方向に折り畳むことができるフレーム構造であれば、カートのフレーム車体構造に制限はない。
The folding self-supporting pet cart according to the present invention is a folding self-supporting pet cart having left and right front legs and left and right rear legs, and having a stand mechanism between the left and right rear legs. When using, keep the left and right front legs and rear legs separated, and when folded, make the left and right front legs and rear legs close to each other, and lift the front wheels at the front legs of the front legs upward When folded, the stand mechanism is capable of self-supporting by descending downward from between the left and right rear legs, and the stand mechanism includes a grounding member provided at a central portion in the left-right direction and both sides of the grounding member in the left-right direction. Each of the left and right stand frames is pivotally attached to the grounding member, the other end is pivotally supported by the left and right rear legs, and the left and right stand frames are self-supporting. State A shaft support piece portion extending outward in the left-right direction from the shaft support portion of the rear leg portion, an inclined portion extending from the shaft support piece portion forward and obliquely downward, and the inclination at the tip of the inclined portion A standing part inclined greatly downward than the part is pivotally attached to the continuous and grounding member, and the center of gravity of the cart is between the rear wheel and the grounding part of the grounding member in a self-standing state, and the standing part is The lower end side is inclined so as to spread forward, and the standing angle θ1 in the front-rear direction with respect to the vertical line is set in a range of 1 to 30 degrees, and the bottom surface of the grounding member has a substantially arc shape in the left-right direction and is in contact with the bottom surface. The ground is formed on an inclined bottom surface that is inclined forward and downward .
In this specification, the advancing direction of a pet cart is expressed as the front, and the direction orthogonal to the advancing direction is expressed as the left-right direction.
The pet cart has a frame body structure, and a bucket portion for accommodating a pet such as a dog is attached to the frame.
For example, an X frame structure in which two frames are crossed can be adopted as a structure for moving the left and right front leg portions and the left and right rear leg portions in the frame structure apart or in the proximity direction. As a structure that folds so as to lift the frame, the handle frame that is pushed by hand and the frame that constitutes the front leg portion are flexibly coupled, and the upper end of the frame that constitutes the rear leg portion is pivotally coupled in the middle of the handle frame. Examples of structures are given.
In the present invention, the frame body structure of the cart is not limited as long as the left and right rear legs can be folded in a direction close to each other.

ここで左右のスタンドフレームは、自立した状態で前記後脚部の軸支部から左右方向外側に延在した軸支片部と、当該軸支片部から前方で斜め下方に向けて折り曲げ延在した傾斜部と、当該傾斜部の先に当該傾斜部よりも大きく下方に傾斜した立設部を連設及び接地部材に枢着し、自立した状態でカートの重心が後輪と接地部材の接地部との間に有するようにするのが好ましく、その場合に立設部の垂直線に対する前後方向の立設角度θ１を１〜３０度の範囲に設定するのがさらに好ましい。 Here, the left and right stand frames are bent in a self-standing manner from the shaft support portion of the rear leg portion extending outward in the left-right direction, and bend and extend forward and obliquely downward from the shaft support piece portion. An inclined portion and an upright portion inclined downwardly more than the inclined portion at the tip of the inclined portion are continuously connected to the grounding member, and the center of gravity of the cart is in a self-standing state with the rear wheel and the grounding portion of the grounding member. In this case, it is more preferable that the standing angle θ1 in the front-rear direction with respect to the vertical line of the standing portion is set in the range of 1 to 30 degrees.

本発明において、接地部材の接地面は前方下方に向けて傾斜した傾斜底面に形成すると、後輪の接地点と接地部材の接地部との間にカートの重心を位置させやすい。
また、後脚部の軸支部形状は断面矩形形状であり、外周部に重ね合せた矩形形状の連結部材を介してスタンドフレームを軸支すると、後脚部とスタンドフレームとの連結部が強固になり、自立安定性がさらに向上する。
また、接地部材の底面を左右方向略円弧形状に形成すると、左右方向の自立安定性も向上する。 In the present invention, if the grounding surface of the grounding member is formed on an inclined bottom surface that is inclined downward and forward, the center of gravity of the cart is easily located between the grounding point of the rear wheel and the grounding part of the grounding member.
In addition, the shape of the shaft support portion of the rear leg portion is rectangular in cross section, and when the stand frame is pivotally supported via a rectangular connection member superimposed on the outer peripheral portion, the connection portion between the rear leg portion and the stand frame is strengthened. As a result, the self-supporting stability is further improved.
In addition, when the bottom surface of the grounding member is formed in a substantially arc shape in the left-right direction, the self-standing stability in the left-right direction is also improved.

本発明に係るペットカートは折り畳む際に左右の後脚部が相互に近接するように水平移動するに伴い、左右のスタンドフレームがＶ字状に折れ曲がり、この左右のスタンドフレームの中央部に枢着した接地部材が下方に下降するので、カートを折り畳むだけでそのまま自立可能になる。
この場合に、カートの重心が後輪の接地点とスタンド機構の接地部材との間の垂直線上に重心が位置するので、カートが前後方向に倒れにくい。
また、接地部材の底面を左右方向略円弧形状に形成すると、左右方向の２ヶ所の接地部でカートを支えるので左右方向にも倒れにくくなる。 When the pet cart according to the present invention is folded, as the left and right rear legs move horizontally so that they are close to each other, the left and right stand frames bend in a V shape, and are pivotally attached to the center of the left and right stand frames. Since the grounding member thus lowered is lowered, it is possible to stand on its own just by folding the cart.
In this case, since the center of gravity of the cart is located on the vertical line between the grounding point of the rear wheel and the grounding member of the stand mechanism, the cart is not easily tilted in the front-rear direction.
Further, when the bottom surface of the grounding member is formed in a substantially arc shape in the left-right direction, the cart is supported by two grounding portions in the left-right direction, so that it is difficult to fall down in the left-right direction.

次にスタンド機構２０について説明する。
スタンド機構２０は図１〜４に示し、カートを折り畳んで自立させた図２（ｂ）の図で説明すると、自立した状態で左右のスタンドフレーム２１，２１は中央部が下降した略Ｖ字状に折れ曲がるようになっている。
断面略矩形形状の後脚部１２の外周側に断面略矩形形状の連結部材２４を重ね合せ、固定部２４ａで固定し、この連結部材２４と後脚部１２の前側の側面とを貫通するように左右スタンドフレーム２１の軸支片部２１ｃを軸支２１ｄした。
左右のスタンドフレーム２１，２１はこの軸支片部２１ｃが自立状態で外側に向けて延在するようになっていて、図３，図４に示すようにこの軸支片部２１ｃから前方及び下方斜めに折り曲げた傾斜部２１ｂを形成し、さらにその先にこの傾斜部２１ｂよりも傾斜角の大きい立設部２１ａを折り曲げ形成してある。
左右の立設部２１ａ，２１ａの下端は左右中央部に位置する接地部材２２と枢着部２３にて枢着してある。
接地部材２２はその底部（底面）２２ｄが円弧状の凹形状になっていて、左右方向両側に接地部２２ａが形成されている。
また、図４，図５に示すように接地部材２２の側部にはスタンドフレームが上下方向に回動可能にした空間部２２ｂと、立設状態で接地部材が左右方向に大きく回動しないようにストッパー部２２ｃを形成した。
また、接地部材２２の接地面は図４に示すように前方下方に傾斜した傾斜底面２２ａ’になっている。

なお、図４（ａ），（ｂ）に示したように立設部２１ａの傾斜方向は前方でも後方側でもよい。
これにより、折り畳んだ状態でかさ高になりやすいペットカートであってもカート重心が後輪１２ａの接地点と接地部材２２の接地部２２ａとの間の垂直線上に位置し、倒れにくくなる。
また、スタンドフレームを傾斜部２１ｂと立設部２１ａとを下方及び中央方向に折り曲げるように形成したので、図６に示すように水平状態では後端部より前方側の奥に入り込み、折り畳むと図３に示すように後輪１２ａから前方に所定の間隔を隔てて接地部材２２が下降する。 Next, the stand mechanism 20 will be described.
The stand mechanism 20 is shown in FIGS. 1 to 4, and will be described with reference to FIG. 2B in which the cart is folded and self-supported. In the self-standing state, the left and right stand frames 21 and 21 are substantially V-shaped with the central portion lowered. It is supposed to bend at the end.
A connecting member 24 having a substantially rectangular cross section is superposed on the outer peripheral side of the rear leg portion 12 having a substantially rectangular cross section, and is fixed by a fixing portion 24 a so as to penetrate the connecting member 24 and the front side surface of the rear leg portion 12. The shaft support piece 21c of the left and right stand frame 21 is pivotally supported 21d.
The left and right stand frames 21 and 21 are such that the shaft support piece portion 21c extends outward in a self-supporting state, and as shown in FIGS. 3 and 4, forward and downward from the shaft support piece portion 21c. An inclined portion 21b that is bent obliquely is formed, and a standing portion 21a that has a larger inclination angle than that of the inclined portion 21b is further bent.
The lower ends of the left and right standing portions 21a and 21a are pivotally connected by a grounding member 22 and a pivot attachment portion 23 located at the center of the left and right.
The grounding member 22 has a bottom (bottom surface) 22d having an arcuate concave shape, and grounding portions 22a are formed on both sides in the left-right direction.
4 and 5, the side portion of the grounding member 22 has a space portion 22b in which the stand frame can be pivoted in the vertical direction, and the grounding member does not pivot significantly in the left-right direction in the standing state. The stopper part 22c was formed in this.
Further, the grounding surface of the grounding member 22 is an inclined bottom surface 22a 'inclined forward and downward as shown in FIG.
In the present invention, the standing angle θ1 in the front-rear direction with respect to the vertical line of the standing portion 21a shown in FIGS. 4A and 4B is in the range of 1 to 30 degrees, preferably 1 to 15 degrees. the angle theta 2 of the bottom surface of the inclined (ground plane) is preferably in the range of 5 to 30 degrees.
In addition, as shown to Fig.4 (a), (b), the inclination direction of the standing part 21a may be the front or back side.
Thereby, even if it is a pet cart that tends to be bulky in the folded state, the center of gravity of the cart is located on the vertical line between the grounding point of the rear wheel 12a and the grounding part 22a of the grounding member 22 and is not easily collapsed.
Further, since the stand frame is formed so that the inclined portion 21b and the standing portion 21a are bent downward and in the central direction, as shown in FIG. As shown in FIG. 3, the grounding member 22 descends at a predetermined interval forward from the rear wheel 12a.
