Description
本発明は、2本のスペアタイヤを重ねた状態で車体下面に搭載するスペアタイヤ搭載装置に関する。 The present invention relates to a spare tire mounting device for mounting two spare tires on a lower surface of a vehicle body in a stacked state.
近年、荷物の積み降ろしに要する労力を軽減するために、前輪を大径タイヤにする一方、後輪を小径タイヤにすることで、荷台床面地上高を低くした低床トラックが実用化されている。このような低床トラックにおいては、タイヤのパンクチュアなどに備えて、径が異なる2本のスペアタイヤを搭載することが必要になる。
2本のスペアタイヤを車両に搭載する技術として、特許文献1に記載されているように、チェーンの先端部に取り付けられた吊り板でディスクホイール下面を受け、2本のスペアタイヤを水平に重ねた状態で車体下面に搭載するスペアタイヤ搭載装置が提案されている。かかるスペアタイヤ搭載装置では、スペアタイヤを1本ずつ搭載できるようにすべく、弾性部材からなる係止部材が取り付けられた支持部材により、上側に位置するスペアタイヤを着脱可能に弾性係止する構造が採用されている。
In recent years, in order to reduce the labor required for loading and unloading luggage, low floor trucks have been put into practical use by lowering the bed floor surface height by making the front wheels large diameter tires and the rear wheels small diameter tires. Yes. In such a low-floor truck, it is necessary to mount two spare tires having different diameters in preparation for tire puncture or the like.
As a technique for mounting two spare tires on a vehicle, as described in Patent Document 1, a suspension plate attached to the tip of the chain receives the lower surface of the disk wheel and stacks the two spare tires horizontally. Spare tire mounting devices have been proposed for mounting on the underside of the vehicle body. In such a spare tire mounting device, a structure in which a spare tire located on the upper side is detachably elastically locked by a support member to which a locking member made of an elastic member is attached so that the spare tire can be mounted one by one. Is adopted.
しかしながら、特許文献1に記載のスペアタイヤ搭載装置では、上側に位置するスペアタイヤを取り外すとき、これを手または足で下方に押して、係止部材の弾性力に抗して支持部材の係止状態を解かなければならなかった。このため、スペアタイヤ搭載装置の後方にリヤバンパが設置される車両では、スペアタイヤに手や足が届き難く、スペアタイヤ搭載装置をそのまま利用することはできなかった。また、スペアタイヤの着脱作業時には、上側に位置するスペアタイヤは弾性部材の弾性力のみにより係止されているため、例えば、予期しない外力が作用したときに外れてしまい、作業の安全性の観点から好ましいものではなかった。 However, in the spare tire mounting device described in Patent Document 1, when removing the spare tire located on the upper side, the spare tire is pushed downward with a hand or a foot, and the supporting member is locked against the elastic force of the locking member. Had to solve. For this reason, in a vehicle in which a rear bumper is installed behind the spare tire mounting device, it is difficult to reach the spare tire with hands and feet, and the spare tire mounting device cannot be used as it is. In addition, when the spare tire is attached or detached, the spare tire located on the upper side is locked only by the elastic force of the elastic member. Therefore, it was not preferable.
本発明は、上記問題に鑑みなされたものであり、作業の安全性を確保しつつ、2本のスペアタイヤを1本ずつ確実に着脱可能にすることを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to reliably attach and detach two spare tires one by one while ensuring work safety.
そのため本発明においては、スペアタイヤキャリアのチェーンを挟んで離間した2位置で、上側に位置するタイヤをその下方位置で保持するタイヤ保持部材を設けた。
ここで、タイヤ保持部材は、左右のサイドレールに両端部が回動可能に取り付けられる略コ字形状の一対のロッドからなる。また、一対のロッドには、その一方を上側に位置するタイヤの下方位置から外方へそらすように回動させると、その他方が反対方向へ回動して、上側に位置するタイヤの下方位置から外方へそらされるリンク機構が設けられる。
Therefore, in the present invention, a tire holding member is provided that holds the tire positioned on the upper side at two positions spaced apart across the chain of the spare tire carrier at the lower position .
Here, the tire holding member is composed of a pair of substantially U-shaped rods whose both ends are rotatably attached to the left and right side rails. Further, when one of the pair of rods is rotated so that one of the rods is deflected outward from the lower position of the tire positioned on the upper side, the other is rotated in the opposite direction, and the lower position of the tire positioned on the upper side is rotated. A link mechanism is provided that is deflected outwardly from the center .
本発明によれば、上下に重ねた2本のスペアタイヤを取り外す場合には、先ず、下側に位置するタイヤを取り外す。この場合、スペアタイヤキャリアを操作してチェーンを繰り出すことで、上側に位置するタイヤをタイヤ保持部材により確実に保持しつつ、下側に位置するタイヤのみを地面に下降させることができる。そして、吊り板を下側に位置するタイヤのホイールディスク穴から取り外すことで、下側に位置するタイヤのみを取り外すことができる。 According to the present invention, when removing two spare tires stacked one above the other, first, the tire located on the lower side is removed. In this case, by operating the spare tire carrier and feeding out the chain, only the lower tire can be lowered to the ground while the upper tire is securely held by the tire holding member. Then, by removing the suspension plate from the wheel disc hole of the tire located on the lower side, only the tire located on the lower side can be removed.
これに続いて、下側に位置するタイヤを取り出した後にスペアタイヤキャリアを操作してチェーンを巻き上げ、吊り板を上側に位置するタイヤのホイールディスクに当接させ、タイヤ保持部材を取り外す。この後、スペアタイヤキャリアを操作してチェーンを繰り出すことにより、該タイヤを地面に下降させる。そして、吊り板をホイールディスク穴から取り外すことでタイヤを取り出すことができる。 Following this, after the lower tire is taken out, the spare tire carrier is operated to wind up the chain, the suspension plate is brought into contact with the wheel disc of the upper tire, and the tire holding member is removed. Thereafter, the spare tire carrier is operated to feed the chain, thereby lowering the tire to the ground. And a tire can be taken out by removing a suspension board from a wheel disc hole.
なお、タイヤの取り付けには、前述の取り外しの手順を逆にすればよい。
本発明では、弾性係止を行わずに、タイヤ保持部材により上側に位置するタイヤを保持して、タイヤの着脱作業を行うため、該作業中に予期しない外力が作用した場合であっても、タイヤがタイヤ保持部材から外れることがなく、作業の安全性を確保できる。
In addition, what is necessary is just to reverse the removal procedure mentioned above for attachment of a tire.
In the present invention, without performing elastic locking, holding the tire positioned on the upper side by the tire holding member and performing the tire mounting / removing operation, even when an unexpected external force is applied during the operation, The tire is not detached from the tire holding member, and work safety can be ensured.
以下、本発明の実施形態について図面を用いて説明する。
図1〜図4は、前輪と後輪との径が異なるスペアタイヤを装着した低床トラックに対して、本発明に係るスペアタイヤ搭載装置1を適用した場合を示している。具体的には、図1は、上下に重ねた2本のスペアタイヤ2,3を搭載している状態を示している。図2は、図1のA−A線からトラックの前方を見た図である。図3は、スペアタイヤ搭載装置1の斜視図である。図4は、スペアタイヤ搭載装置1の各部品の取り付け状態を示す斜視図である。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a case where the spare tire mounting device 1 according to the present invention is applied to a low-floor truck equipped with spare tires having different diameters of front wheels and rear wheels. Specifically, FIG. 1 shows a state in which two spare tires 2 and 3 stacked one above the other are mounted. FIG. 2 is a view of the front of the truck as viewed from the line AA in FIG. FIG. 3 is a perspective view of the spare tire mounting device 1. FIG. 4 is a perspective view showing an attachment state of each component of the spare tire mounting device 1.
スペアタイヤ搭載装置1は、トラックの前後方向に平行に延びて車台フレームを構成する左右のサイドレール4a,4bの後部に設けられている。左右のサイドレール4a,4bの後端には、バンパブラケット11を介して、車幅方向に延びるリヤバンパ12が取り付けられている。
スペアタイヤ搭載装置1は、クロスメンバ5、スペアタイヤキャリア6およびタイヤ保持部材としての一対のロッド20,21を含んで大別構成されている。
The spare tire mounting device 1 is provided at the rear part of the left and right side rails 4a and 4b that extend in parallel with the longitudinal direction of the truck and constitute the chassis frame. A rear bumper 12 extending in the vehicle width direction is attached to the rear ends of the left and right side rails 4 a and 4 b via a bumper bracket 11.
The spare tire mounting device 1 is roughly configured to include a cross member 5, a spare tire carrier 6, and a pair of rods 20 and 21 as tire holding members.
クロスメンバ5は、左右のサイドレール4a,4bの後部において、左右のサイドレール4a,4bに渡って車幅方向に平行に2本架設されている。クロスメンバ5の両端は、左右のサイドレール4a,4bの上端面に固定されている。
スペアタイヤキャリア6は、2つのクロスメンバ5の略中央位置に固定されている。スペアタイヤキャリア6には、チェーン9の繰り出しおよび巻き上げが可能な駆動装置が内蔵されている。チェーン9の先端部9aには、スペアタイヤ2,3のディスクホイール穴2a,3aを挿通可能で、ディスクホイール3bの下面からスペアタイヤ2,3を吊り上げ可能な吊り板7が取り付けられている。
Two cross members 5 are installed in parallel in the vehicle width direction over the left and right side rails 4a and 4b at the rear portions of the left and right side rails 4a and 4b. Both ends of the cross member 5 are fixed to upper end surfaces of the left and right side rails 4a and 4b.
The spare tire carrier 6 is fixed at a substantially central position between the two cross members 5. The spare tire carrier 6 has a built-in drive device that can feed and wind up the chain 9. A suspension plate 7 that can be inserted through the disk wheel holes 2a and 3a of the spare tires 2 and 3 and can lift the spare tires 2 and 3 from the lower surface of the disk wheel 3b is attached to the tip 9a of the chain 9.
スペアタイヤキャリア6のチェーン9を挟んで離間した2位置には、上側に位置するタイヤ2を保持する一対のロッド20,21が配置されている。ロッド20,21は、左右のサイドレール4a,4bに両端部が回動可能に取り付けられている。
ロッド20は、スペアタイヤキャリア6のチェーン9よりトラックの前方に配置される一方、ロッド21は、該チェーン9よりトラックの後方に配置されている。
A pair of rods 20 and 21 for holding the tire 2 located on the upper side are disposed at two positions spaced apart across the chain 9 of the spare tire carrier 6. Both ends of the rods 20 and 21 are attached to the left and right side rails 4a and 4b so as to be rotatable.
The rod 20 is arranged in front of the truck from the chain 9 of the spare tire carrier 6, while the rod 21 is arranged behind the truck from the chain 9.
これらのロッド20,21は、棒状の部材が車幅方向に延び、中央部がトラックの下方に向けて凹状に窪んだ略コ字形状をしている。これにより、タイヤ2の下面を受けるタイヤ保持部20a,21aが形成される。ロッド20,21の両端部は、それぞれ左右のサイドレール4a,4bに形成された貫通孔22,23に挿通された後に、例えば車幅方向の移動を規制するピンが取り付けられる。 These rods 20 and 21 have a substantially U shape in which a rod-shaped member extends in the vehicle width direction and a central portion is recessed in a concave shape toward the lower side of the track. Thereby, tire holding portions 20a and 21a that receive the lower surface of the tire 2 are formed. Both ends of the rods 20 and 21 are inserted through through-holes 22 and 23 formed in the left and right side rails 4a and 4b, respectively, and then, for example, pins for restricting movement in the vehicle width direction are attached.
ここで、ロッド20,21の少なくとも一端にはアームが固定されている。図では、ロッド20の一端に、該一端から上方に向かって延びるアーム20bが固定される一方、ロッド21の一端に、該一端から下方に向かって延びるアーム21bが固定されている。
これらのアーム20b,21bには、リンク部材25の端部25a,25bが回転可能に取り付けられている。これにより、リンク機構が構成され、一対のロッド20,21を連動させることが可能となる。
Here, an arm is fixed to at least one end of the rods 20 and 21. In the figure, an arm 20 b extending upward from one end is fixed to one end of the rod 20, and an arm 21 b extending downward from the one end is fixed to one end of the rod 21.
Ends 25a and 25b of the link member 25 are rotatably attached to these arms 20b and 21b. Thereby, a link mechanism is comprised and it becomes possible to make a pair of rods 20 and 21 interlock.
例えば、図5に示すように、ロッド21のタイヤ保持部21aをトラックの後方に引くことで、その両端部を回転中心としてアーム21bが回転され、リンク部材25がトラックの後方に引かれる。これにより、ロッド20の両端部を回転中心としてアーム20bが回転され、保持部20aがトラックの前方に開かれる。
次に、上下に重ねた2本のスペアタイヤ2,3を1本ずつ取り外す場合について説明する。
For example, as shown in FIG. 5, by pulling the tire holding portion 21a of the rod 21 to the rear of the track, the arm 21b is rotated with the both ends thereof as the center of rotation, and the link member 25 is pulled to the rear of the track. Thereby, the arm 20b is rotated with the both ends of the rod 20 as the rotation center, and the holding portion 20a is opened forward of the track.
Next, a case where two spare tires 2 and 3 stacked one above the other are removed one by one will be described.
図1の状態から、スペアタイヤキャリア6を操作してチェーン9を繰り出すことで、図6に示すように、上側に位置するタイヤ2の下面がロッド20,21の保持部20a,21aに受けられ、下側に位置するタイヤ3のみが地面まで下降される。
この後に、図7に示すように、吊り板7を下側に位置するタイヤ3のホイールディスク穴3aから取り外し、スペアタイヤキャリア6の操作によりチェーン9を巻き上げて、上側に位置するタイヤ2のディスクホイール2bの下面に吊り板7を当接させた後、ロッド20,21を上側に位置するタイヤ2の下方位置から外す開操作を行う。また、下側に位置するタイヤ3を取り出す。
From the state shown in FIG. 1, the spare tire carrier 6 is operated to feed the chain 9 so that the lower surface of the tire 2 located on the upper side is received by the holding portions 20a and 21a of the rods 20 and 21, as shown in FIG. Only the lower tire 3 is lowered to the ground.
Thereafter, as shown in FIG. 7, the suspension plate 7 is removed from the wheel disc hole 3a of the tire 3 located on the lower side, the chain 9 is wound up by the operation of the spare tire carrier 6, and the disc of the tire 2 located on the upper side. After the suspension plate 7 is brought into contact with the lower surface of the wheel 2b, an opening operation for removing the rods 20 and 21 from the lower position of the tire 2 located on the upper side is performed. Further, the lower tire 3 is taken out.
そして、図8に示すように、スペアタイヤキャリア6を操作してチェーン9を繰り出す。これにより、タイヤ2を地面に下降させる。
その後、図9に示すように、吊り板7を該タイヤ2のディスクホイール穴2aから取り外し、タイヤ2を取り出すと共に、スペアタイヤキャリア6の操作によりチェーン9を巻き上げる。
Then, as shown in FIG. 8, the spare tire carrier 6 is operated to feed the chain 9 out. Thereby, the tire 2 is lowered to the ground.
Thereafter, as shown in FIG. 9, the suspension plate 7 is removed from the disc wheel hole 2 a of the tire 2, the tire 2 is taken out, and the chain 9 is wound up by operating the spare tire carrier 6.
以上により、上下に重ねた2本のスペアタイヤ2,3を一本ずつ確実に取り外すことができる。
なお、スペアタイヤ2,3を取り付ける場合には、前述のタイヤ取り外しの逆の手順で行えばよい。
As described above, the two spare tires 2 and 3 stacked one above the other can be reliably removed one by one.
In addition, what is necessary is just to perform in the reverse procedure of the above-mentioned tire removal, when attaching the spare tires 2 and 3. FIG.
