Abstract
Description
本発明は、大型のキャスターの取付け部と小型のキャスターの取付け部を両者有する大小サイズ違いのキャスターの取付け構造を備えた台車に関する。 The present invention relates to a trolley provided with a structure for mounting casters of different sizes, each having both a mounting portion for a large caster and a mounting portion for a small caster.
従来、台車に対する固定をきわめて簡単に行うキャスターはあるが、裏面に取り付ける大型のキャスターの取付け部と小型のキャスターの取付け部を両者有する大小サイズ違いのキャスターの取付け構造を備えた台車は、開示されていない。 Conventionally, there are casters that are very easily fixed to a dolly, but a dolly having a large and small size caster mounting structure having both a large caster mounting part and a small caster mounting part mounted on the back surface is disclosed. Not not.
しかし、台車の裏面に大小サイズ違いの複数種のキャスターを取り付けた方が好ましい場合もある。 However, in some cases, it is preferable to attach a plurality of types of casters of different sizes to the back surface of the carriage.
例えば冷蔵庫など背の高い荷物を運ぶときに、台車のキャスターが大きいと、その分荷物の高さも大きくなりエレベーターやドアなどで引っ掛かるため、別の小さいキャスターの台車を用意しなければいけなかった。このように、従来は、大小サイズ違いのキャスターを一台の台車にそれぞれ取り付けるのではなく、大小サイズ違いのキャスターを有する複数台の台車を用意し、異なる荷物に応じて複数台の台車を用意せざるをえなかった。 For example, when carrying tall luggage such as a refrigerator, if the dolly's casters are large, the height of the dolly will be correspondingly large, and the elevators or doors will be caught, so we had to prepare a dolly for another small caster. In this way, conventionally, instead of mounting casters of different sizes on one trolley, each trolley has multiple trolleys with casters of different sizes, and multiple trolleys for different luggage. I had no choice but to do it.
この発明の目的は、大小サイズ違いのキャスターを一台の台車にそれぞれ取り付けることが可能な台車を提供する点にある。 An object of the present invention is to provide a trolley capable of mounting casters of different sizes on a single trolley.
前記課題を達成するため、本発明は、
天板の裏面側に縦リブと横リブが略十字に形成され、キャスターの座板の下面周辺部に穴を有し、この穴にリブに設けられた仮突起を仮止めし、リブに設けられた取付け穴に螺合する、キャスターの取付け部を構成した台車であって、
前記キャスターの取付け部は、大型キャスターと小型キャスターを取り付ける２種類の取付け部からなり、
前記大型キャスターの取付け部は、前記縦リブに設けられた大型キャスターへの取付け穴と、同縦リブに設けられた大型キャスターへの仮突起と、並びに、隣接する縦リブに設けられた大型キャスターへの仮突起と、同縦リブに設けられた大型キャスターへの取付け穴とを備え、
前記小型キャスターの取付け部は、前記大型キャスターの取付け部の内側にあり、前記横リブに並行して設けられた小型キャスターへの仮突起と、同横リブに並行して設けられた小型キャスターへの取付け穴と、並びに、前記横リブに並行して設けられた小型キャスターへの取付け穴と、同横リブに並行して設けられた小型キャスターへの取付け穴とを備えた
ことを特徴とする台車を採用した。
In order to achieve the above object, the present invention provides
Vertical ribs and horizontal ribs are formed in a cross shape on the back side of the top plate, and there is a hole in the peripheral portion of the lower surface of the seat plate of the caster, and the temporary projection provided on the rib is temporarily fixed in this hole and provided on the rib. A dolly that constitutes a caster mounting part that is screwed into the mounting hole
The mounting portion of the caster comprises two types of mounting portions for mounting a large caster and a small caster,
The mounting portion of the large caster includes a mounting hole for the large caster provided on the vertical rib, a temporary projection for the large caster provided on the vertical rib, and a large caster provided on the adjacent vertical rib. , And a mounting hole for a large caster provided on the vertical rib,
The mounting portion of the small caster is located inside the mounting portion of the large caster, and the temporary projection for the small caster provided in parallel with the lateral rib and the small caster provided in parallel with the lateral rib are provided. And a mounting hole for a small caster provided in parallel with the lateral rib, and a mounting hole for a small caster provided in parallel with the lateral rib. A dolly was adopted.
なお、好ましくは、前記大型キャスターの取付け部は、
横リブを挟んで縦リブ上に設けられた大型キャスターへの取付け穴と大型キャスターへの仮突起と、並びに同横リブを挟んで縦リブ上に設けられた大型キャスターへの仮突起と大型キャスターへの取付け穴を備え、
前記小型キャスターの取付け部は、前記大型キャスターの取付け部の内側にあり、縦リブ間を二分する中間縦リブを挟んで横補助リブ上に設けられた小型キャスターへの仮突起と小型キャスターへの取付け穴と、前記縦リブ間を二分する中間縦リブを挟んで横補助リブ上に設けられた小型キャスターへの取付け穴と小型キャスターへの仮突起

In addition, preferably, the mounting portion of the large caster is
Mounting holes for large casters on the vertical ribs across the horizontal ribs and temporary projections on the large casters, as well as temporary projections for large casters on the vertical ribs across the horizontal ribs and large casters With a mounting hole for
The mounting portion of the small caster is inside the mounting portion of the large caster, and a temporary projection for the small caster and a small caster provided on the horizontal auxiliary rib sandwiching the intermediate vertical rib that divides the vertical rib into two. It is desirable to provide a mounting hole and a mounting hole for a small caster and a temporary projection for the small caster, which are provided on the horizontal auxiliary rib with an intermediate vertical rib that divides the vertical rib into two.
従って、この発明が、例えば直径１００ｍｍの大型のキャスターを備えた台車であれば、この大型のキャスターの取付け部に取り付ける場合、縦リブに設けられた仮突起を大型キャスターの穴に嵌入し、同時に隣接する縦リブに設けられた大型キャスターへの取付け穴を螺合する。一方、例えば直径７５ｍｍの小型キャスターを備えた台車にするには、この大型のキャスターの取付け部から例えば直径１００ｍｍのキャスターを取り外し、例えば直径７５ｍｍの小型のキャスターを横リブに並行して設けられた前記小型キャスターの取付け部に取り付ければよい。すなわち、前記横リブと並行して設けられた小型キャスターへの仮突起にキャスターの穴を仮止めし、前記横リブと並行して設けられた小型キャスターへの取付け穴を螺合して、小型キャスターの取付け部とすればよい。 Therefore, if the present invention is, for example, a trolley provided with a large caster having a diameter of 100 mm, when attaching to a mounting portion of this large caster, a temporary protrusion provided on the vertical rib is fitted into a hole of the large caster, and at the same time, The mounting holes for large casters provided on the adjacent vertical ribs are screwed together. On the other hand, for example, to make a dolly having a small caster with a diameter of 75 mm, a caster with a diameter of 100 mm was removed from the mounting portion of this large caster, and a small caster with a diameter of 75 mm was provided in parallel with the lateral rib. It may be attached to the attachment portion of the small caster. That is, the holes of the casters are temporarily fixed to the temporary projections for the small casters provided in parallel with the lateral ribs, and the mounting holes for the small casters provided in parallel with the lateral ribs are screwed together to reduce the size. It may be used as a mounting portion for casters.
