Description

キャリーバッグCarry Bag
　本発明は、接地状態での運搬が可能なキャリーバッグに関する。 The present invention relates to a carry bag that can be transported in a grounded state.
　キャリーバッグはバッグ本体の底面に複数の車輪が取り付けられたカバンであり、接地状態での運搬が可能なことから、収容量の多い旅行カバンや仕事用カバンとして普及している。このようなキャリーバッグのうち収容量の多い大型のキャリーバッグは、バッグ本体を垂直に立てた状態での運搬が可能なように、通常、バッグ本体の底面に４～６個の車輪が取り付けられている。 The carry bag is a bag having a plurality of wheels attached to the bottom surface of the bag body and can be transported in a grounded state, so that it is widely used as a travel bag or a work bag with a large capacity. Among such carry bags, large carry bags with a large capacity usually have 4 to 6 wheels attached to the bottom of the bag body so that the bag body can be transported in a vertical position. ing.
　これに対して、収容量が少ない小型のキャリーバッグは、バッグ本体の底面に２個の車輪が取り付けられており、バッグ本体を斜めに倒した状態でハンドルを引いて運搬するようになっている。この方が、バッグ本体を垂直に立てて運搬するよりも速く、また楽に運搬できるからである。このような運搬形態のため、小型のキャリーバッグでは、バッグ本体の底面のうち背面（斜めに倒したときに下に位置する面）側の両端部に２個の車輪が該バッグ本体の背面と平行な車軸を中心に回転可能に取り付けられている。そして、バッグ本体の底面のうち前面側にはバッグ本体を垂直に立てた状態で自立させることができるように、突部が固定されている。突部は、自立させたキャリーバッグが移動してしまうことを防止するストッパとしても機能する。 On the other hand, a small carry bag with a small amount of storage has two wheels attached to the bottom surface of the bag body, and is carried by pulling a handle while the bag body is tilted obliquely. . This is because the bag body can be transported faster and more easily than when the bag body is stood vertically. Because of such a transport mode, in a small carry bag, two wheels are attached to both ends of the back surface (the surface positioned below when tilted obliquely) of the bottom surface of the bag body. It is mounted so that it can rotate around a parallel axle. And the protrusion is being fixed to the front side among the bottom surfaces of a bag main body so that it can be made to stand in the state which stood the bag main body perpendicularly | vertically. The protrusion also functions as a stopper that prevents the carry bag that is self-supporting from moving.
　上述した小型のキャリーバッグは通常、飛行機内に持ち込みが可能なカバンとして販売されている。ところが、飛行機内の通路は小型のキャリーバッグの横幅よりも狭いことが多く、また、通路で他の乗客とすれ違うこともあるため、バッグ本体を斜めに倒した状態での運搬が難しい。小型のキャリーバッグの車輪は、バッグ本体を斜めに倒した状態で引いて運搬するときの移動方向に回転するよう構成されているため、それ以外の方向に回転させることができない。 The above-mentioned small carry bag is usually sold as a bag that can be carried on an airplane. However, since the passage in an airplane is often narrower than the width of a small carry bag and may pass by other passengers in the passage, it is difficult to carry the bag with the bag body tilted down. The wheels of the small carry bag are configured to rotate in the moving direction when the bag body is pulled and transported in an inclined state, and thus cannot be rotated in any other direction.
　これに対して、特許文献１には、バッグ本体の底面に２個のボール車輪と２個の足（ストッパ）を取り付けたキャリーバッグが開示されている。２個のボール車輪と２個の足はそれぞれ対向配置されている。２個の足はいずれも断面半円状の部材から構成されていて、円弧面で地面と接触するようにバッグ本体の底面に取り付けられている。２個のボール車輪と２個の足が接地した状態にあるとき、バッグ本体は垂直に起立した状態となる。 On the other hand, Patent Document 1 discloses a carry bag in which two ball wheels and two feet (stoppers) are attached to the bottom surface of the bag body. The two ball wheels and the two legs are arranged opposite to each other. Each of the two legs is composed of a member having a semicircular cross section, and is attached to the bottom surface of the bag body so as to be in contact with the ground with an arc surface. When the two ball wheels and the two feet are in contact with the ground, the bag body stands upright.

　特許文献１のキャリーバッグでは、360°任意の方向に回転可能なボール車輪が用いられているため、バッグ本体を傾斜させ２個の足を地面から離間させることにより、バッグ本体を任意の方向へ移動させることができる。 The carry bag of Patent Document 1 uses a ball wheel that can rotate 360 ° in any direction, so the bag body can be moved in any direction by tilting the bag body and separating the two feet from the ground. Can be moved.
　しかしながら、２個の足を接地面から離間させてバッグ本体を移動させるためには、バッグ本体を傾斜させ、更にバッグ本体を運搬する間、その傾斜状態を維持する必要がある。バッグ本体の傾斜状態を維持するにはバッグ本体の重量に応じた負荷が該バッグ本体の保持者にかかるため、傾斜状態を維持しつつバッグ本体を任意の方向に移動させることは容易ではないという問題があった。 However, in order to move the bag body by separating the two feet from the ground contact surface, it is necessary to incline the bag body and maintain the inclined state while the bag body is being transported. In order to maintain the inclined state of the bag body, a load corresponding to the weight of the bag body is applied to the holder of the bag body, so it is not easy to move the bag body in any direction while maintaining the inclined state. There was a problem.
　本発明が解決しようとする課題は、バッグ本体を任意の方向に容易に且つ軽い負荷で運搬することができるキャリーバッグを提供することである。 The problem to be solved by the present invention is to provide a carry bag that can easily carry a bag body in an arbitrary direction with a light load.
　上記課題を解決するために成された本発明は、走行面に接地した状態で運搬可能なキャリーバッグであって、
　a) バッグ本体と、
　b) 前記バッグ本体の底面の前半部及び後半部のいずれか一方の左右両側に、該底面に対して垂直な取付軸周りに回転可能に取り付けられた２個のキャスターと、
　c) 前記前半部及び後半部の他方に固定された、前記キャスターとともに前記走行面に接地させたときに前記バッグ本体が傾斜状態で自立するような高さを有するストッパと
を備えることを特徴とする。 The present invention made to solve the above problems is a carry bag that can be transported in a grounded state on a running surface,
a) the bag body;
b) two casters attached to the left and right sides of either the front half or the rear half of the bottom surface of the bag body so as to be rotatable about an attachment axis perpendicular to the bottom surface;
and c) a stopper fixed to the other of the front half and the rear half, and having a height that allows the bag body to stand up in an inclined state when grounded to the running surface together with the casters. To do.
　本発明では、キャリーバッグの非運搬時は、キャスターとストッパの両方を接地させる。このとき、バッグ本体は傾斜した状態で自立し、倒れることがない。バッグ本体が傾斜状態で自立するような高さを有するストッパとは、バッグ本体の底面から走行面側に突出する長さが、キャスターよりもストッパの方が所定の寸法だけ小さいことをいう。バッグ本体が傾斜状態で自立しているときのストッパと走行面の接触状態は面接触、線接触、点接触のいずれでも良いが、バッグ本体を安定させ、且つ、バッグ本体が移動してしまうことを防止するために、ストッパと走行面が面接触することが好ましい。一方、キャリーバッグの運搬時は、バッグ本体が傾斜して自立した状態から、バッグ本体を垂直に立てた状態にする。ストッパはキャスターよりもバッグ本体の底面から走行面側に突出する長さが小さいため、バッグ本体を垂直にたてた状態にすると、ストッパが走行面から離間する。これにより、ストッパによって邪魔されることなく垂直に立てた状態で任意の方向にバッグ本体を移動させることができる。また、垂直に立てた状態ではバッグ本体の荷重が該バッグ本体の保持者にほとんど加わらない。さらに、キャスターが取り付けられた側の部分（前半部又は後半部）が下側にくるように該バッグ本体を斜めに倒すことにより、バッグ本体を引いて運搬することもできる。 In the present invention, when the carry bag is not transported, both the caster and the stopper are grounded. At this time, the bag body is self-supporting in an inclined state and does not fall down. The stopper having such a height that the bag body is self-supporting in an inclined state means that the length of the stopper protruding from the bottom surface of the bag body toward the running surface is smaller by a predetermined dimension than the caster. The contact state between the stopper and the running surface when the bag body is in an inclined state may be any of surface contact, line contact, and point contact, but the bag body is stabilized and the bag body moves. In order to prevent this, it is preferable that the stopper and the running surface are in surface contact. On the other hand, when carrying the carry bag, the bag body is made to stand vertically from the state where the bag body is inclined and self-supporting. Since the stopper is smaller in length than the caster and protrudes from the bottom surface of the bag body toward the traveling surface side, the stopper is separated from the traveling surface when the bag body is vertically set. Thereby, a bag main body can be moved to arbitrary directions in the state stood vertically, without being disturbed by a stopper. Further, when the bag is erected vertically, the load on the bag body is hardly applied to the holder of the bag body. Furthermore, the bag body can be pulled and transported by tilting the bag body diagonally so that the portion (front half or rear half) on which the casters are attached is on the lower side.
　上記キャリーバッグにおいては、前記キャスターが、前記取付軸を中心に回転可能な車輪支持部と、該車輪支持部に前記バッグ本体の底面と平行な回転軸周りに回転可能に支持された車輪とを備え、前記取付軸の軸中心線と前記回転軸の軸中心線が交差しないことが好ましい。 In the carry bag, the caster includes a wheel support portion that is rotatable about the mounting shaft, and a wheel that is rotatably supported by the wheel support portion around a rotation axis that is parallel to the bottom surface of the bag body. It is preferable that the axial center line of the mounting shaft does not intersect the axial center line of the rotating shaft.
　この構成では、バッグ本体を斜めに倒した状態では、車輪がバッグ本体を運搬する方向に回転するように、典型的には、車輪支持部の取付軸が車輪の回転軸の下側に位置するように該車輪支持部が取付軸周りに回転する。また、バッグ本体を起立させた状態で移動させるときはその移動させる方向に応じて、車輪の回転軸が適切な方向を向くように車輪支持部が取付軸周りに回転する。このため、バッグ本体を任意の方向に容易に運搬することができる。 In this configuration, the attachment shaft of the wheel support portion is typically located below the rotation shaft of the wheel so that the wheel rotates in the direction of carrying the bag body when the bag body is tilted obliquely. Thus, the wheel support portion rotates around the mounting shaft. In addition, when the bag body is moved in an upright state, the wheel support portion rotates around the attachment shaft so that the rotation shaft of the wheel faces an appropriate direction according to the moving direction. For this reason, a bag main body can be easily conveyed in arbitrary directions.
　また、上記キャリーバッグにおいては、前記キャスターの車輪と前記ストッパを接地させたときの前記バッグ本体の傾斜角度が、5°～15°の範囲内にあることが好ましい。このような角度範囲に設定することにより、自立状態にあるキャリーバッグが安定し、わずかな力で倒れてしまうことを防止できる。 In the carry bag, it is preferable that an inclination angle of the bag body when the wheels of the caster and the stopper are grounded is in a range of 5 ° to 15 °. By setting to such an angle range, the carry bag in a self-supporting state can be stabilized and prevented from falling down with a slight force.
　上記構成の本発明に係るキャリーバッグによれば、バッグ本体を斜めに倒した状態で引いて運搬する動作と起立させた状態で任意の方向に運搬する動作の両方を容易に且つ、軽い負荷で行うことができる。 According to the carry bag of the present invention configured as described above, both the operation of pulling and transporting the bag body in an inclined state and the operation of transporting it in an arbitrary direction in an upright state can be easily performed with a light load. It can be carried out.

　図２に示すように、キャスター１４は、バッグ本体１１の底面に固定された取付座１４１と、該取付座１４１にベアリング１４２を介して回転自在に取り付けられた側面視三角形状のブラケット１４３と、該ブラケット１４３に、回転軸１４４を介して回転可能に支持された車輪１４５とから構成されている。本実施例ではベアリング１４２が取付軸に相当する。キャスター１４は、ブラケット１４３の回転中心Ｌ１（図２(b)に二点鎖線で示す。）と、回転軸１４４が交差しないように構成されている。このような構成により、バッグ本体１１が垂直状態にあるとき、回転軸１４４の中心を通る鉛直線Ｌ２（同図に一点鎖線で示す。）とブラケット１４３の回転中心Ｌ１は異なる位置にある。 As shown in FIG. 2, the caster 14 includes a mounting seat 141 fixed to the bottom surface of the bag main body 11, a bracket 143 having a triangular shape in side view, which is rotatably attached to the mounting seat 141 via a bearing 142, The bracket 143 includes a wheel 145 that is rotatably supported via a rotating shaft 144. In this embodiment, the bearing 142 corresponds to the mounting shaft. The caster 14 is configured such that the rotation center L1 of the bracket 143 (indicated by a two-dot chain line in FIG. 2B) and the rotation shaft 144 do not intersect. With such a configuration, when the bag body 11 is in a vertical state, the vertical line L2 (shown by a one-dot chain line in the drawing) passing through the center of the rotation shaft 144 and the rotation center L1 of the bracket 143 are at different positions.
　ストッパ１５の高さは、バッグ本体１１の底面からキャスター１４の車輪１４５の下端部までの距離よりも短く設定されており、キャスター１４の車輪１４５を接地した状態でバッグ本体１１を垂直に起立させたときは、ストッパ１５は接地しないようになっている（図１(a)参照）。このため、ストッパ１５とキャスター１４の車輪１４５の両方を接地させると、図３に示すように、バッグ本体１１は鉛直方向から所定の角度θだけ傾斜する。このとき、ストッパ１５は走行面に面接触するように構成されている。また、ストッパ１５とキャスター１４の車輪１４５の両方が接地しているときのバッグ本体１１の傾斜角度θは、ストッパ１５とキャスター１４の車輪１４５の両方が接地状態にあるときのバッグ本体１１の倒れ難さを考えると5°～15°の範囲が好ましい。ただし、バッグ本体１１の容量が大きい場合はθを5°よりも小さくしても良く、また、バッグ本体１１の容量が小さい場合はθを15°よりも大きくしても良い。つまり、角度θはバッグ本体１１の容量に応じた適宜の値（ストッパ１５とキャスター１４の車輪１４５の両方が接地状態にあるときのバッグ本体１１が倒れにくい適宜の角度）に設定すると良い。 The height of the stopper 15 is set to be shorter than the distance from the bottom surface of the bag main body 11 to the lower end of the wheel 145 of the caster 14, and the bag main body 11 stands upright with the wheel 145 of the caster 14 grounded. In this case, the stopper 15 is not grounded (see FIG. 1 (a)). For this reason, when both the stopper 15 and the wheel 145 of the caster 14 are grounded, as shown in FIG. 3, the bag body 11 is inclined by a predetermined angle θ from the vertical direction. At this time, the stopper 15 is configured to come into surface contact with the traveling surface. In addition, the inclination angle θ of the bag body 11 when both the stopper 15 and the wheel 145 of the caster 14 are grounded is such that the bag body 11 falls when both the stopper 15 and the wheel 145 of the caster 14 are grounded. Considering the difficulty, the range of 5 ° to 15 ° is preferable. However, when the capacity of the bag body 11 is large, θ may be smaller than 5 °, and when the capacity of the bag body 11 is small, θ may be larger than 15 °. That is, the angle θ may be set to an appropriate value according to the capacity of the bag body 11 (an appropriate angle at which the bag body 11 is not easily tilted when both the stopper 15 and the wheel 145 of the caster 14 are in a grounded state).
　上記構成のキャリーバッグ１０の使用方法を説明する。まず、キャリーバッグ１０の非運搬時は、キャスター１４の車輪１４５とストッパ１５の両方を走行面に接地させる。この結果、バッグ本体１１は傾斜状態で自立する（図３）。このとき、ストッパ１５は、走行面と面接触しているため、バッグ本体１１が移動してしまうことが防止される。 A method of using the carry bag 10 having the above configuration will be described. First, when the carry bag 10 is not transported, both the wheel 145 and the stopper 15 of the caster 14 are grounded to the traveling surface. As a result, the bag body 11 is self-supporting in an inclined state (FIG. 3). At this time, since the stopper 15 is in surface contact with the running surface, the bag body 11 is prevented from moving.
　バッグ本体１１が自立した状態から、キャスター１４が下側に来るようにバッグ本体１１を斜めに倒した状態にすると、ハンドル１３を引いて運搬することができる。このとき、２個のキャスター１４は、それぞれ車輪１４５の回転軸１４４が地面と水平になるように、且つ、車輪１４５の回転軸１４４よりもブラケット１４３の回転中心Ｌ１の方が下側に位置するようにブラケット１４３が回転する。このため、図４に示すように、車輪１４５の回転軸１４４がバッグ本体１１の進行方向Ａと垂直になり、バッグ本体１１をスムーズに運搬することができる。 When the bag body 11 is tilted obliquely so that the casters 14 are on the lower side from the state in which the bag body 11 is self-supporting, the handle 13 can be pulled and transported. At this time, the two casters 14 are positioned so that the rotation shaft 144 of the wheel 145 is horizontal with the ground, and the rotation center L1 of the bracket 143 is positioned below the rotation shaft 144 of the wheel 145. Thus, the bracket 143 rotates. For this reason, as shown in FIG. 4, the rotating shaft 144 of the wheel 145 becomes perpendicular to the traveling direction A of the bag body 11, and the bag body 11 can be smoothly transported.
　一方、自立した状態にあるバッグ本体１１を角度θだけ起こして、垂直に起立した状態にすると、図１(a)に示すように、ストッパ１５が走行面から離間する。この状態で、バッグ本体１１を左方（図５に矢印Ｂ１で示す方向）に移動させると、図５に示すように、２個のキャスター１４は、車輪１４５の回転軸１４４を通る鉛直線Ｌ２がブラケット１４３の回転中心Ｌ１よりも右側に位置するようにブラケット１４３が回転する。また、垂直に起立した状態のバッグ本体１１を右方（図５に矢印Ｂ２で示す方向）に移動させると２個のキャスター１４は、車輪１４５の回転軸１４４を通る鉛直線Ｌ２がブラケット１４３の回転中心Ｌ１よりも左側に位置するようにブラケット１４３が回転する。さらに、図示しないが、垂直に起立した状態のバッグ本体１１を左方及び右方以外の方向に移動させた場合も、車輪１４５の回転軸１４４を通る鉛直線Ｌ２がブラケット１４３の回転中心Ｌ１よりも、移動方向の反対側にくるように、２個のキャスター１４のブラケット１４３が回転する。
　バッグ本体１１が垂直に起立した状態では、バッグ本体１１の荷重はほとんど該バッグ本体１１の保持者に加わらない。このため、垂直に起立した状態にあるバッグ本体１１を任意の方向に容易に且つ軽負荷で移動させることができる。 On the other hand, when the bag main body 11 in a self-standing state is raised by an angle θ to stand vertically, the stopper 15 is separated from the running surface as shown in FIG. In this state, when the bag body 11 is moved to the left (the direction indicated by the arrow B1 in FIG. 5), the two casters 14 are connected to the vertical line L2 passing through the rotation shaft 144 of the wheel 145, as shown in FIG. The bracket 143 rotates so that is positioned on the right side of the rotation center L1 of the bracket 143. Further, when the bag body 11 in a vertically standing state is moved to the right (in the direction indicated by the arrow B2 in FIG. 5), the two casters 14 have a vertical line L2 passing through the rotating shaft 144 of the wheel 145 so that the bracket 143 The bracket 143 rotates so as to be located on the left side of the rotation center L1. Further, although not shown, even when the bag body 11 in a vertically upright state is moved in a direction other than left and right, the vertical line L2 passing through the rotation shaft 144 of the wheel 145 is more than the rotation center L1 of the bracket 143. However, the brackets 143 of the two casters 14 rotate so as to be opposite to the moving direction.
In the state where the bag body 11 stands vertically, the load on the bag body 11 hardly applies to the holder of the bag body 11. For this reason, the bag main body 11 in a vertically upright state can be easily moved in any direction with a light load.
　なお、本発明は上記した実施例に限定されるものではなく、適宜の変更が可能である。
例えば、バッグ本体１１の底面のうちハンドル１３が取り付けられた面側にストッパ１５を、それと反対側に２個のキャスター１４を取り付けても良い。このような構成のキャリーバッグ１０においては、バッグ本体１１を斜めに倒した状態で運搬するときは、図６に示すように、ハンドル１３が取り付けられた面が上に来るように該バッグ本体１１を斜めに倒す。 In addition, this invention is not limited to an above-described Example, A suitable change is possible.
For example, the stopper 15 may be attached to the side of the bottom surface of the bag body 11 where the handle 13 is attached, and the two casters 14 may be attached to the opposite side. In the carry bag 10 having such a configuration, when the bag body 11 is transported in an inclined state, as shown in FIG. 6, the bag body 11 so that the surface to which the handle 13 is attached is on the top. Tilt diagonally.
　上記実施例では、ストッパを、キャスターとともに接地したときに走行面と面接触するような断面形状にしたが、線接触するような形状（例えば断面半円状のストッパ）にしたり、点接触するような形状（例えば半球状）にしたりしても良い。また、樹脂等の弾性部材からストッパを構成し、接地したときにバッグ本体の荷重を受けて弾性変形して面接触するようにしても良い。さらに、ストッパを２個以上の部材から構成しても良い。 In the above embodiment, the stopper has a cross-sectional shape that comes into surface contact with the running surface when grounded together with the caster. However, the stopper has a shape that makes a line contact (for example, a semicircular stopper in cross section) or a point contact. It may be a simple shape (for example, hemispherical). Alternatively, the stopper may be made of an elastic member such as resin, and when it is grounded, it receives the load of the bag body and is elastically deformed to make surface contact. Furthermore, you may comprise a stopper from two or more members.
　上記実施例では、取付軸と車輪の回転軸が交差しないようなキャスターを用いたが、取付軸と車輪の回転軸が交差する構成のキャスターを用いることも可能である。このようなキャスターの場合は、上記実施例で示したキャスターに比べて、キャリーバッグを移動させたときにその移動方向に応じてキャスターが取付軸周りに回転するタイミングが若干遅れる可能性があるが、最終的には、キャリーバッグの移動方向と回転軸が直交するため、キャリーバッグを任意の方向に移動させることができる。 In the above embodiment, a caster is used in which the attachment shaft and the wheel rotation axis do not intersect. However, a caster having a configuration in which the attachment shaft and the wheel rotation axis intersect may be used. In the case of such a caster, compared with the caster shown in the above embodiment, when the carry bag is moved, there is a possibility that the timing at which the caster rotates around the attachment shaft is slightly delayed according to the moving direction. In the end, since the moving direction of the carry bag is orthogonal to the rotation axis, the carry bag can be moved in any direction.
