Abstract

PROBLEM TO BE SOLVED: To provide a transport cart using an alignment cover in which a fixed wheel (fixed wheel middle abdomen) is covered by an alignment cover, and therefore a caster of the other transport cart is prevented from coming into abutment with the fixed wheel, and the nesting and unlocking work is stably made.SOLUTION: A transport cart has free casters 10 installed at four corners in the lower surface of a floor frame 1. A fixed caster 20 without swivel action is fixed in an intermediate position of a front traveling direction 46 in a lower surface. The fixed caster 20 is configured such that an axle 26 of a fixed wheel 25 is axially stopped to axial plate members 21, 21, and a V-shaped abutment member 22 is fixed in an aperture of the longitudinal direction of the axial plate members 21, 21. The axial plate member 21 and the abutment member 22 constitute an alignment cover 24. The bottom edge 22a of the abutment member 22 and the bottom edge 21a of the axial plate member 21 are positioned more downward than a "fixed wheel middle abdomen 29" (H<H), and the bottom edge 22a of the abutment member 22 is positioned more downward than a "caster middle abdomen 17" of a caster 12 (H<H).SELECTED DRAWING: Figure 2

Description

本発明は、主に保管時に作用するキャスター用の整列カバーを用いた運搬用台車に関する。   The present invention relates to a transporting carriage using an alignment cover for casters that acts mainly during storage.

運搬用台車では、荷物の搬送に使用しない保管時に、ネスティングと称して複数の台車を平面視で重ねて、保管スペースを小さくしていた(特許文献1、図4。特許文献2)。この場合、固定キャスター、自在キャスターとの車輪を支持するキャスターフレームが、車輪の全周360°の内、上端部60°程度を占めているだけで、車輪の外周の上端部を除き、300°程度が露出していた。   In the transport cart, during storage that is not used for transporting luggage, a plurality of carts are overlapped in plan view, referred to as nesting, and the storage space is reduced (Patent Document 1, FIG. 4, Patent Document 2). In this case, the caster frame that supports the wheels of the fixed caster and the free caster only occupies about 60 ° of the upper end of the entire 360 ° circumference of the wheel. The degree was exposed.

運搬用台車をネスティングする際に、静止している運搬用台車の自在車輪に、他の運搬用台車を動かして重ねる場合、静止している運搬用台車の自在キャスターの車輪に、近づけた他の運搬用台車の固定キャスターの車輪が接触する場合があった。この際、静止している自在キャスターの車輪が障害となり、近づけた他の運搬用台車の進行が妨げられることが生じていた。   When nesting a transport cart, if another transport cart is moved and stacked on the free wheel of a stationary transport cart, In some cases, the wheels of the fixed casters of the transportation cart contact. At this time, the wheels of the free casters that were stationary became an obstacle, and the progress of other transport carts that were brought close to each other was hindered.

このような車輪の接触を避けるために、車輪にカバーを設けることも考えられるが、一般に、台車にカバー類を設けた例として、ブレーキ装置を格納するために四角筒のケース(平面視で長方形)で車輪の下端部を除いた部分を覆った例(特許文献3、図7、図8)、電動の走行台車で中央にある駆動輪の車輪の下端部を除いた部分を覆った例(特許文献4)が提案されている。前者のケースの作用効果に言及が無いがブレーキ装置を保護するためと考えられ、後者の覆いは駆動輪に人が触れる場合など安全を考慮したものと考えられる。さらに、これらの例はネスティングが不可能な構造の台車で、かつ車輪を保護するため、台車の平面視と同様に平面視で長方形の形状となっていた。   In order to avoid such a wheel contact, it is conceivable to provide a cover on the wheel. Generally, as an example of providing a cover on the carriage, a rectangular tube case (rectangular in plan view) is used to store the brake device. ) In which the portion excluding the lower end of the wheel is covered (Patent Document 3, FIG. 7, FIG. 8), and the portion excluding the lower end of the wheel of the driving wheel at the center in the electric traveling carriage ( Patent Document 4) has been proposed. Although there is no mention of the effect of the former case, it is considered to protect the brake device, and the latter cover is considered to take safety into consideration when a person touches the driving wheel. Furthermore, these examples are carts having a structure that cannot be nested, and in order to protect the wheels, they have a rectangular shape in plan view as in the plan view of the cart.

したがって、仮に特許文献3、4のケースや覆いをネスティング可能な台車の固定車輪に応用できた場合であっても、ケースや覆いの角部が、自在キャスター10の車輪12に当たるので(図1(a))、上記問題点を解決できなかった。   Therefore, even if the case and cover of Patent Documents 3 and 4 can be applied to a fixed wheel of a cart capable of nesting, the corner of the case or cover hits the wheel 12 of the free caster 10 (FIG. 1 ( a)) The above problems could not be solved.

本発明は、自在キャスターと固定キャスターとを有し、ネスティング可能な台車で、固定キャスターに、斜めの当接面を有する整列カバーを設けたので、前記問題点を解決した。   The present invention solves the above-mentioned problems because the cart has a free caster and a fixed caster, and is a nestable cart, and the fixed caster is provided with an alignment cover having an oblique contact surface.

図面に基づいて、この発明の実施態様を説明する。   Embodiments of the present invention will be described with reference to the drawings.

1.運搬用台車40の構成 1. Configuration of the carriage 40

(1) 平面視で、「ハ」字状に配置した主床フレーム材2、2の広い側の端部を長連結材3で連結固定して、狭い側の端部を短連結材4で連結固定して、床フレーム1を構成する。ここで、床フレーム1の長さ方向、すなわち広い側の端部と狭い側の端部とを結ぶ線の矢示46方向を「前走行方向」とする(図2、図5〜図7)。
主床フレーム材2、2の広い側の端部の下面に、それぞれキャスター取付板7、7を固定する。また、主床フレーム材2、2の狭い側の端部で、短連結材4の下面にまたがって、それぞれキャスター取付板8、8を固定する(図1(a))。したがって、床フレーム1の四隅にキャスター取付板7、8が配置される。
(1) In the plan view, the wide side ends of the main floor frame members 2 and 2 arranged in a “C” shape are connected and fixed with the long connecting material 3, and the narrow side ends with the short connecting material 4. The floor frame 1 is configured by connecting and fixing. Here, the length direction of the floor frame 1, that is, the direction indicated by the arrow 46 connecting the end portion on the wide side and the end portion on the narrow side is referred to as the “front running direction” (FIGS. 2, 5 to 7). .
Caster mounting plates 7 and 7 are fixed to the lower surfaces of the end portions on the wide side of the main floor frame materials 2 and 2, respectively. In addition, the caster mounting plates 8 and 8 are fixed at the narrow end portions of the main floor frame materials 2 and 2 across the lower surface of the short connecting material 4 (FIG. 1A). Therefore, the caster mounting plates 7 and 8 are arranged at the four corners of the floor frame 1.

(2) 床フレーム1のキャスター取付板8、8の下面にそれぞれ、旋回自在の自在キャスター10(通常、進行方向46で前側になる)を取り付ける。また、床フレーム1のキャスター取付板7、7の下面にそれぞれ、旋回自在の自在キャスター10a(通常、進行方向46で後ろ側になる)を取り付ける。自在キャスター10、自在キャスター10aは通常同一構造で、自在キャスター10、10aは、垂直軸周りに旋回するキャスター本体11の下端部に、自在車輪12の車軸13が軸止めされている(図2(c))。
自在車輪12(12a)で、自在車輪12(12a)が接地面45に接地した際に、接地面45と平行な面が車軸13を通る車軸水平面15が、自在車輪12の外周と交わる点を「自在車輪中腹部17」とする(図2(b)(c))。
(2) A swivelable caster 10 (usually on the front side in the traveling direction 46) is attached to the lower surface of the caster mounting plates 8 and 8 of the floor frame 1, respectively. Further, a swivelable caster 10a (usually on the rear side in the traveling direction 46) is attached to the lower surfaces of the caster mounting plates 7 and 7 of the floor frame 1, respectively. The universal caster 10 and the universal caster 10a usually have the same structure. In the universal casters 10, 10a, the axle 13 of the universal wheel 12 is fixed to the lower end portion of the caster body 11 turning around the vertical axis (FIG. 2 ( c)).
When the universal wheel 12 (12a) is in contact with the grounding surface 45, the axle horizontal plane 15 passing through the axle 13 with a plane parallel to the grounding surface 45 intersects the outer periphery of the universal wheel 12 when the universal wheel 12 (12a) contacts the grounding surface 45. It is set as “universal wheel middle abdomen 17” (FIGS. 2B and 2C).

(3) また、床フレーム1の前走行方向46で中間位置に、すなわち前後方向で、キャスター取付板7、7とキャスター取付板8、8との間で、両主床フレーム2、2の下面に、それぞれ、旋回機能が無い固定キャスター20、20を固定する。
固定キャスター20は以下のように構成される(図2、図3)。所定間隔を空けて略平行に軸板部材21、21を配置して、軸板部材21、21に固定車輪25の車軸26を軸止めする。軸板部材21、21の前後方向の開口に、平面視で「V字状」の当接部材22、22を固定する。当接部材22は、前後方向(前走行方向46)に、角度θ(θ=75°程度)で配置された両当接板23、23から構成する。なお、当接部材22(当接板23)が走行方向で斜めに形成される「当接面」を構成し、当接板23の角度θは、自在キャスター10(10a)の自在車輪12(12a)に当接する部分であるので、
θ<90°
が望ましい。また、θを小さする自在車輪12との関係では好ましいが、小さくすると平面視で、矢示46(走行方向)で、当接部材22が長くなりすぎるので、現実的ではなく、
60°<θ<90°
程度が実用的な範囲と考えられる。
また、自在キャスター10(10a)の自在車輪12の材質による摩擦に対抗して、あるいは当接板23の外面の摩擦を少なくして、自在キャスター10(10a)の自在車輪12(12a)と当たった際に、滑るように逃げることができれば、
90°<θ<150°
程度とすることもできる(図示していない)。また、平面視で、当接板23、23の先端部を部分円形とし(図4)、または当接部材22(当接板23、23)の全体を半球形(図示していない)、にすることもできる。
(3) Also, the lower surfaces of the two main floor frames 2 and 2 between the caster mounting plates 7 and 7 and the caster mounting plates 8 and 8 at the intermediate position in the front traveling direction 46 of the floor frame 1, that is, in the front-rear direction. The fixed casters 20 and 20 having no turning function are respectively fixed.
The fixed caster 20 is configured as follows (FIGS. 2 and 3). The shaft plate members 21 and 21 are arranged substantially in parallel with a predetermined interval, and the axle 26 of the fixed wheel 25 is fixed to the shaft plate members 21 and 21. The “V-shaped” contact members 22, 22 in a plan view are fixed to the front and rear openings of the shaft plate members 21, 21. The contact member 22 includes both contact plates 23 and 23 arranged at an angle θ (about θ = 75 °) in the front-rear direction (forward travel direction 46). The contact member 22 (contact plate 23) constitutes a “contact surface” that is formed obliquely in the traveling direction, and the angle θ of the contact plate 23 is set to the free wheel 12 of the universal caster 10 (10a). 12a) is in contact with the part,
θ <90 °
Is desirable. In addition, it is preferable in relation to the free wheel 12 that decreases θ, but if it is decreased, the contact member 22 becomes too long in the arrow 46 (traveling direction) in a plan view.
60 ° <θ <90 °
The degree is considered a practical range.
Further, the free caster 10 (10a) hits the free wheel 12 (12a) of the free caster 10 (10a) against the friction caused by the material of the free wheel 12 or by reducing the friction of the outer surface of the contact plate 23. If you can run away,
90 ° <θ <150 °
It can also be a degree (not shown). Further, in a plan view, the front ends of the contact plates 23 and 23 are partially circular (FIG. 4), or the entire contact member 22 (contact plates 23 and 23) is hemispherical (not shown). You can also

(4) また、固定車輪25で、車輪26が接地面45に接地した際に、接地面45と平行な面が車軸26を通る車軸水平面28が、固定車輪25の外周と交わる点を「固定車輪中腹部29」とする。 (4) In addition, when the wheel 26 touches the grounding surface 45 with the fixed wheel 25, the “fixed” is the point where the axle horizontal plane 28 passing through the axle 26 has a plane parallel to the grounding surface 45 intersects the outer periphery of the fixed wheel 25. It is referred to as a wheel middle abdomen 29 ”.

また、当接部材22の下縁22aは、軸板部材21の下縁21aと同一に形成され、当接部材22の下縁22aおよび軸板部材21の下縁21aは、いずれも「固定車輪中腹部29、29」よりも下方に位置している(図2(c))。すなわち、接地面45から固定車輪中腹部29(車軸26)までの高さHとし、接地面45から当接部材22の下縁22aまでの高さHとした場合、
<H
となっている(図2(c))。
また、当接部材22の下縁22aは、自在車輪12(12a)の「自在車輪中腹部17」よりも下方に位置している(図2(c))。すなわち、接地面45から自在車軸中腹部17(車軸13)までの高さH11とすると、
<H11
となっている(図2(c))。
The lower edge 22a of the contact member 22 is formed in the same manner as the lower edge 21a of the shaft plate member 21, and both the lower edge 22a of the contact member 22 and the lower edge 21a of the shaft plate member 21 are “fixed wheels”. It is located below the middle abdomen 29, 29 "(FIG. 2 (c)). That is, when the height H 1 from the ground plane 45 to a fixed wheel in the abdomen 29 (axle 26), and a height H 2 of up to the lower edge 22a of the abutting member 22 from the ground plane 45,
H 2 <H 1
(FIG. 2 (c)).
Further, the lower edge 22a of the abutting member 22 is positioned below the "universal wheel middle abdomen 17" of the universal wheel 12 (12a) (Fig. 2 (c)). That is, when the height H 11 from the ground contact surface 45 to the free axle middle abdomen portion 17 (axle 13),
H 2 <H 11
(FIG. 2 (c)).

(5) また、ここで、軸板部材21、21と当接部材22、22とで、整列カバー24を構成する(図2)。固定キャスター20は。整列カバー24の軸板部材21の上縁(=当接部材22の上縁)が、主床フレーム材2、2の下面に固定されている。 (5) Here, the shaft cover members 21 and 21 and the contact members 22 and 22 constitute an alignment cover 24 (FIG. 2). The fixed caster 20 is. The upper edge (= the upper edge of the contact member 22) of the shaft plate member 21 of the alignment cover 24 is fixed to the lower surfaces of the main floor frame members 2 and 2.

(6) 床フレーム1上に、荷物を載せるパレット34を起伏可能に取り付けし、床フレーム1の広い側の端、狭い側の端に、荷崩れ防止用の側面パネル35、35を取り付ける。以上のようにして、この発明の運搬用台車40を構成する(図5)。 (6) A pallet 34 on which a load is placed is mounted on the floor frame 1 so that it can be raised and lowered, and side panels 35, 35 for preventing load collapse are attached to the wide side end and the narrow side end of the floor frame 1. As described above, the transport carriage 40 of the present invention is configured (FIG. 5).

2.運搬用台車40の使用 2. Use of the carriage 40

(1) この運搬用台車40では、通常の運搬用台車と同様に、パレット34上に荷物を載せて、運搬できる。この場合は、旋回しない固定キャスター20が中央部にあるので、全部自在キャスターの場合に較べ、直進性の高い走行ができ、かつ前後の自在キャスター10、10aで、ある程度の曲進や切り返しにも対応できる。 (1) With this transporting carriage 40, a load can be placed on the pallet 34 and transported in the same manner as an ordinary transporting carriage. In this case, since the fixed caster 20 that does not turn is located in the central portion, the vehicle can travel straight ahead as compared with the case of all the free casters, and the forward and backward free casters 10 and 10a can be bent and turned to some extent. Yes.

(2) また、運搬用台車40を使用しない場合には、通常の運搬用台車と同様に、パレット34を折り畳み、あるいは、広い側の側面パネル35に沿って起立させて、さらに狭い側の側面パネル35を取り外して広い側の側面パネルの外側に沿わせ(あるいは狭い側の側面パネル35を取り外して外部に保管して)、床フレーム1の前側(狭い側の)の上面を露出させる。
この状態で、複数の運搬用台車40、40A、40B、・・・を、床フレーム1の主床フレーム材2、2の側面を互いに沿わせるようにして、ネスティングできる(図6、図7)。
この際、一の運搬用台車40を走行して狭い側(前側)を、静止している他の運搬用台車40Bの広い側(後ろ側)に向けて押し込める(図6(a)、図7(a))。この際、自在キャスター10、10A、10B同士が衝突した場合には、自在キャスター10(10a)、10A(10aA)、10B(10aB)の自在車輪12(12a)、12A(12aA)、12B(12aB)は旋回するので、一の運搬用台車40の走行方向に影響は無い。
また、他の運搬用台車40B、40Aの自在キャスター10A(10aA)、10B(10aB)の自在車輪12A(12aA)、12B(12aB)の一部または全部が、矢示46方向以外の方向に向いている場合であっても、一の運搬用台車40の固定キャスター20に、他の運搬用台車40B、40Aの自在キャスター10A(10aA)、10B(10aB)が衝突した場合、固定キャスター20の整列カバー24が自在キャスター10A(10aA)、10B(10aB)の自在車輪12A(12aA)、12B(12aB)に当接して、整列カバー24の当接部材22で、自在キャスター10A(10aA)、10B(10aB)を旋回させて、一の運搬用台車40の固定車輪25が他の運搬用台車40B、40Aに当接することはない(図6(a)(b)、図7(a)(b))。
なお、通常考えられるキャスター同士の衝突は、一の運搬用台車40の固定キャスター20が、他の運搬用台車40A、40Bの後ろ側の自在車輪12aA、12aBに衝突する場合である(図1(b))。
