まず、本発明の配達用被牽引台車が前記従来の被牽引台車ないしリヤカーと共通する点について説明する。   First, the point that the delivery tow truck of the present invention is in common with the conventional towed carriage or rear car will be described.

すなわち、本発明の配達用被牽引台車１は、基部３に左右一対の車輪５、５を備えさせると共に牽引用二輪車７に連結するための連結杆９を該基部３より前方に突設し、該連結杆９を介して該牽引用二輪車７の後部に分離自在に連結される点において、前記従来の被牽引台車ないしリヤカーと共通する。なお、基部３とは配達用被牽引台車の骨格をなす部分をいうものとする。符号１１に示すものは、基部３上に備えさせた積載部である。   That is, the delivery tow truck 1 of the present invention includes a pair of left and right wheels 5 and 5 on the base 3 and a connecting rod 9 for connecting to the tow motorcycle 7 protruding forward from the base 3. In common with the conventional towed carriage or rear car in that it is separably connected to the rear part of the towing motorcycle 7 through the connecting rod 9. In addition, the base part 3 shall mean the part which makes the frame | skeleton of the tow truck for delivery. What is indicated by reference numeral 11 is a loading section provided on the base 3.

連結杆９の前端部９ａは、牽引用二輪車７の後部に分離自在に連結される。すなわち、一例として、牽引用二輪車７の後部に取付杆１３を備えさせ、該取付杆１３より雌ねじを備えた支持筒１５を上方に突設し、連結杆９の前端部９ａには該支持筒１５に嵌脱自在に外嵌されるリング体１７を備えさせ、該リング体１７を支持筒１５に外嵌した状態で固定雄ねじ１９を支持筒１５の雌ねじに螺合させる。固定雄ねじ１９は該固定雄ねじ１９を回転させるための頭部２１を備えている。この事例においては、連結杆９のリング体１７を牽引用二輪車７後部の取付杆１３に突設した支持筒１５に外嵌し、固定雄ねじ１９を支持筒１５の雌ねじに螺合させることにより、連結杆９を牽引用二輪車７の後部に連結することができる。連結杆９を牽引用二輪車７の後部から分離する際には、固定雄ねじ１９を支持筒１５から外し、連結杆９のリング体１７を牽引用二輪車７の支持筒１５から外す。図１〜図４参照。   The front end portion 9 a of the connecting rod 9 is detachably connected to the rear portion of the towed motorcycle 7. That is, as an example, a mounting rod 13 is provided at the rear portion of the traction motorcycle 7, a support cylinder 15 provided with an internal thread is projected upward from the mounting rod 13, and the support cylinder 15 is provided at the front end 9 a of the connecting rod 9. 15 is provided with a ring body 17 that is externally fitted to the support cylinder 15, and the fixed male screw 19 is screwed onto the female thread of the support cylinder 15 in a state where the ring body 17 is externally fitted to the support cylinder 15. The fixed male screw 19 includes a head 21 for rotating the fixed male screw 19. In this case, the ring body 17 of the connecting rod 9 is externally fitted to the support cylinder 15 projecting from the mounting rod 13 at the rear of the towed motorcycle 7, and the fixed male screw 19 is screwed into the female screw of the support cylinder 15, The connecting rod 9 can be connected to the rear part of the towed motorcycle 7. When the connecting rod 9 is separated from the rear portion of the towing motorcycle 7, the fixed male screw 19 is removed from the support tube 15, and the ring body 17 of the connecting rod 9 is removed from the support tube 15 of the towing motorcycle 7. See FIGS.

牽引用二輪車７としては、自転車、オートバイ等が使用される。図示の事例における牽引用二輪車７は自転車である。符号２３に示すものは車輪、符号２５に示すものはハンドル、符号２７に示すものはサドルである。   As the towing motorcycle 7, a bicycle, a motorcycle, or the like is used. The towed motorcycle 7 in the illustrated example is a bicycle. Reference numeral 23 indicates a wheel, reference numeral 25 indicates a handle, and reference numeral 27 indicates a saddle.

次に、本発明における図１〜図１４に示す事例について説明する。   Next, examples of the present invention shown in FIGS. 1 to 14 will be described.

配達用被牽引台車１における基部３には一端にキャスター３１を備えたキャスター支持脚３３を該キャスター３１が路面に接離自在となるように支軸３５を介して回動自在に枢着する。 A caster support leg 33 provided with a caster 31 at one end is pivotally attached to the base 3 of the delivery towed cart 1 via a support shaft 35 so that the caster 31 can be brought into and out of contact with the road surface.

該基部３と該キャスター支持脚３３との間には該キャスター支持脚３３を該キャスター３１が路面から常時離れる方向に引く第一ばね手段３７を取り付ける。第一ばね手段３７は、一例としてコイルばねとする。   A first spring means 37 is attached between the base 3 and the caster support leg 33 to pull the caster support leg 33 in a direction in which the caster 31 always leaves the road surface. The first spring means 37 is a coil spring as an example.

該キャスター支持脚３３を該第一ばね手段３７の力に抗して回動させて該キャスター３１が路面に接地した状態で該キャスター支持脚３３を固定するためのキャスター支持脚固定手段３９を設ける。換言すれば、該キャスター３１が路面に接地した状態で該第一ばね手段３７の力に抗して該キャスター支持脚３３を固定するためのキャスター支持脚固定手段３９を設ける。 Caster support leg fixing means 39 is provided for fixing the caster support leg 33 in a state where the caster support leg 33 is rotated against the force of the first spring means 37 and the caster 31 is in contact with the road surface. . In other words, caster support leg fixing means 39 is provided for fixing the caster support legs 33 against the force of the first spring means 37 with the casters 31 in contact with the road surface.

該キャスター支持脚固定手段３９は、一例として、前記キャスター支持脚３３には先端に屈曲部４１ａを設けた係止杆４１を突設し、前記基部３には第一水平ピン４３を上下動自在に配設し、該キャスター支持脚３３が該キャスター３１を路面に接地させた位置にあるときに該第一水平ピン４３を下降させて該係止杆４１の屈曲部４１ａに係止（図１０、図１１参照）させることにより、前記第一ばね手段３７の力に抗して該キャスター支持脚３３を当該位置に固定するようにしてなるものである。該第一水平ピン４３を上昇させたときには該第一水平ピン４３が該係止杆４１の屈曲部４１ａから脱出して該キャスター支持脚３３の固定が解除される。 As an example, the caster support leg fixing means 39 is provided with a locking rod 41 provided with a bent portion 41a at the tip of the caster support leg 33, and the first horizontal pin 43 can be moved up and down on the base 3. When the caster support leg 33 is in a position where the caster 31 is in contact with the road surface, the first horizontal pin 43 is lowered and locked to the bent portion 41a of the locking rod 41 (FIG. 10). 11), the caster support leg 33 is fixed at the position against the force of the first spring means 37. When the first horizontal pin 43 is raised, the first horizontal pin 43 escapes from the bent portion 41a of the locking rod 41, and the fixing of the caster support leg 33 is released.

図示の事例においては、前記第一水平ピン４３は、前記基部３に一対の支持板４５、４５を取り付け、各支持板４５、４５に上下方向の長孔４７、４７を形成し、該長孔４７、４７に該第一水平ピン４３を上下動自在に支持させている。   In the illustrated example, the first horizontal pin 43 has a pair of support plates 45, 45 attached to the base 3, and vertical holes 47, 47 are formed in the support plates 45, 45. The first horizontal pin 43 is supported by 47 and 47 so as to be movable up and down.

前記連結杆９は、前記基部３に対する前方への突出状態が解除可能である。   The connecting rod 9 can be released from the forward protruding state with respect to the base 3.

一例として、該記連結杆９は該基部３に対し取り外し可能である。   As an example, the connecting rod 9 is removable with respect to the base 3.

すなわち、連結杆９を基部３に対し取り外し可能ならしめるために、一例として、基部３の前端部には角筒状の筒状受け部５１を備えさせ、該連結杆９の角筒状の後端部９ｂを該筒状受け部５１に対し挿脱自在とし、該連結杆９の後端部９ｂを該筒状受け部５１に挿嵌した状態で該連結杆９の後端部９ｂを該筒状受け部５１に固定するための連結杆後端部固定手段５３を備えさせる。   That is, in order to make the connecting rod 9 detachable from the base portion 3, as an example, the front end portion of the base portion 3 is provided with a rectangular tubular receiving portion 51, and the rear end of the connecting rod 9 has a rectangular tube shape. The end 9b can be inserted into and removed from the cylindrical receiving portion 51, and the rear end 9b of the connecting rod 9 is inserted into the cylindrical receiving portion 51 while the rear end 9b of the connecting rod 9 is inserted into the cylindrical receiving portion 51. A connecting rod rear end fixing means 53 for fixing to the cylindrical receiving portion 51 is provided.

連結杆後端部固定手段５３は、一例として、該連結杆９の後端部９ｂに第一透孔５５を形成し、該筒状受け部５１には該第一透孔５５に対応する第二透孔５７を形成し、該連結杆９の後端部９ｂを該筒状受け部５１に挿嵌した状態で、固定ピン５９を該第二透孔５７と第一透孔５５とに挿入することにより、該連結杆９の後端部９ｂを該筒状受け部５１に固定するようになす。   For example, the connecting rod rear end fixing means 53 has a first through hole 55 formed in the rear end portion 9 b of the connecting rod 9, and the cylindrical receiving portion 51 has a first hole 55 corresponding to the first through hole 55. The fixing pin 59 is inserted into the second through hole 57 and the first through hole 55 in a state where the two through holes 57 are formed and the rear end portion 9b of the connecting rod 9 is inserted into the cylindrical receiving portion 51. By doing so, the rear end portion 9 b of the connecting rod 9 is fixed to the cylindrical receiving portion 51.

続いて、本発明における図１５〜図４３に示す事例について説明する。   Then, the example shown to FIGS. 15-43 in this invention is demonstrated.

この事例においては、キャスター支持脚３３’は、配達用被牽引台車１の進行方向に関し横方向に回動自在になるように支軸３５’を介して基部３の前側に備えさせる。すなわち、キャスター支持脚３３’は、基部３における前縁の前方に配設される。キャスター３１は、直立状態のキャスター支持脚３３’に対し水平方向に旋回自在である。   In this case, the caster support leg 33 ′ is provided on the front side of the base portion 3 via the support shaft 35 ′ so as to be rotatable in the lateral direction with respect to the traveling direction of the delivery towed carriage 1. That is, the caster support leg 33 ′ is disposed in front of the front edge of the base portion 3. The caster 31 is pivotable in the horizontal direction with respect to the upright caster support leg 33 '.

この事例におけるキャスター支持脚固定手段３９’について、図２４〜図３３を参照して説明する。 The caster support leg fixing means 39 'in this case will be described with reference to FIGS.

すなわち、基部３には第二水平ピンハンドル６１を備えた第二水平ピン６３を上下動自在に配設する。符号６５に示すものは、第二水平ピン６３を上下方向に案内するガイド孔である。ガイド孔６５は、キャスター支持脚３３’が直立状態にあるときに、下方に向かって徐々に該キャスター支持脚３３’に接近する方向に傾斜している。第二水平ピン６３は、上昇位置にあるときには、第二水平ピンハンドル６１と共に自重により下降する。 That is, a second horizontal pin 63 having a second horizontal pin handle 61 is disposed on the base 3 so as to be movable up and down. Reference numeral 65 denotes a guide hole for guiding the second horizontal pin 63 in the vertical direction. When the caster support leg 33 'is in an upright state, the guide hole 65 is inclined in a direction gradually approaching the caster support leg 33' downward. When the second horizontal pin 63 is in the raised position, it is lowered by its own weight together with the second horizontal pin handle 61.

キャスター支持脚３３’をキャスター３１が接地する位置まで下方に回動させると共に第二水平ピン６３を下降させたときには、第二水平ピン６３が該キャスター支持脚３３’に当接して第一ばね手段３７’の力に抗して該キャスター支持脚３３’を当該位置に固定し（図２５参照。）、該第二水平ピン６３を上昇させたときには該第二水平ピン６３が該キャスター支持脚３３’から離れて該キャスター支持脚３３’の固定が解除されるようになす（図２７、図２８参照）。すなわち、第二水平ピン６３が該キャスター支持脚３３’の端面６７に当接しない位置まで上昇したときには、該キャスター支持脚３３’は上方に回動することが可能となる。第一ばね手段３７’は、一例としてコイルばねとする。 When the caster support leg 33 ′ is rotated downward to a position where the caster 31 contacts the ground and the second horizontal pin 63 is lowered, the second horizontal pin 63 comes into contact with the caster support leg 33 ′ and the first spring means. The caster support leg 33 'is fixed at the position against the force of 37' (see FIG. 25), and when the second horizontal pin 63 is raised, the second horizontal pin 63 is moved to the caster support leg 33. The caster support leg 33 ′ is released from the position “from” (see FIGS. 27 and 28). That is, when the second horizontal pin 63 rises to a position where it does not contact the end surface 67 of the caster support leg 33 ', the caster support leg 33' can be rotated upward. The first spring means 37 'is a coil spring as an example.

このように、該キャスター支持脚３３’の固定が解除されたときには、キャスター支持脚３３’は、第一ばね手段３７’により上方に回動し、キャスター３１が路面から離れた状態に保持される（図２９参照）。 In this way, when the caster support leg 33 ′ is released, the caster support leg 33 ′ is rotated upward by the first spring means 37 ′, and the caster 31 is held away from the road surface. (See FIG. 29).

上方に回動したキャスター支持脚３３’をキャスター３１が接地する位置まで下方に回動させる際には、該キャスター３１を第一ばね手段３７’の力に抗して作業者が足で押し下げればよい。このとき、第二水平ピン６３は、第二水平ピンハンドル６１と共に自重により下降し、該キャスター支持脚３３’に当接して該キャスター支持脚３３’を固定する。図３０〜図３３参照。 When the caster support leg 33 ′ rotated upward is rotated downward to the position where the caster 31 contacts the ground, the operator can push the caster 31 with the foot against the force of the first spring means 37 ′. That's fine. At this time, the second horizontal pin 63 is lowered by its own weight together with the second horizontal pin handle 61, and abuts on the caster support leg 33 'to fix the caster support leg 33'. See FIGS.

図３４〜図３８に示す事例においては、前記連結杆９における前記基部３に対する前方への突出状態を解除可能ならしめるために、該連結杆９を該基部３に対し上下方向に回動自在に枢着している（図１８参照。）。符号６８に示すものは、該連結杆９を上下方向に回動自在に支持する支軸である。   In the case shown in FIGS. 34 to 38, the connecting rod 9 can be pivoted up and down with respect to the base portion 3 so that the protruding state of the connecting rod 9 with respect to the base portion 3 can be released. It is pivoted (see FIG. 18). What is indicated by reference numeral 68 is a support shaft which supports the connecting rod 9 so as to be rotatable in the vertical direction.

すなわち、基部３の前部には下端に第三水平ピン６９を備えた第三水平ピンハンドル７１を前後方向に傾動自在に配設する。符号７３に示すものは、第三水平ピン６９を前後方向に案内するガイド孔である。ガイド孔７３は、連結杆３が前方に突出した状態にあるときに、基部３から離れるにつれて徐々に該連結杆３に接近する方向に傾斜している。符号７４に示すものは、第三水平ピンハンドル７１の傾動中心である。   That is, a third horizontal pin handle 71 having a third horizontal pin 69 at the lower end is disposed at the front of the base 3 so as to be tiltable in the front-rear direction. Reference numeral 73 denotes a guide hole for guiding the third horizontal pin 69 in the front-rear direction. When the connecting rod 3 is in a state of protruding forward, the guide hole 73 is gradually inclined toward the connecting rod 3 as the distance from the base 3 is increased. What is indicated by reference numeral 74 is the tilt center of the third horizontal pin handle 71.

基部３と第三水平ピンハンドル７１との間には該第三水平ピンハンドル７１を第三水平ピン６９が基部３から離れる方向に引く第二ばね手段７５を配設する。第二ばね手段７５は、一例としてコイルばねとする。連結杆９が該基部３に対し前方に突出した状態にあるときには該第三水平ピン６９は第二ばね手段７５の力により常時該連結杆９に当接して該連結杆９を当該突出状態に固定する（図３５、図３６参照。）。第二ばね手段７５の力に抗して該第三水平ピンハンドル７１を該第三水平ピン６９が基部３に接近する方向に傾動させたときには該第三水平ピン６９が連結杆９から離れて該連結杆９の固定が解除される（図３７参照。）。すなわち、第三水平ピン６９が連結杆９の端面７７に当接しない位置まで基部３に接近したときには、該連結杆９は下方に回動することが可能となる。図３６、図３７参照。   Between the base portion 3 and the third horizontal pin handle 71, a second spring means 75 for pulling the third horizontal pin handle 71 in a direction in which the third horizontal pin 69 separates from the base portion 3 is disposed. The second spring means 75 is a coil spring as an example. When the connecting rod 9 protrudes forward with respect to the base 3, the third horizontal pin 69 always abuts against the connecting rod 9 by the force of the second spring means 75 so that the connecting rod 9 enters the protruding state. It fixes (refer FIG. 35, FIG. 36). When the third horizontal pin handle 71 is tilted in the direction in which the third horizontal pin 69 approaches the base 3 against the force of the second spring means 75, the third horizontal pin 69 moves away from the connecting rod 9. The fixing of the connecting rod 9 is released (see FIG. 37). That is, when the third horizontal pin 69 approaches the base 3 to a position where it does not come into contact with the end surface 77 of the connecting rod 9, the connecting rod 9 can rotate downward.
