るようになつている。 Conventionally, as shown in FIG. 1, a generally U-shaped support wall 2 is integrally provided on the lower surface of a bottom body 1 as shown in FIG. At the same time, a leaf spring 5 is fixed to the inner bottom surface of the support wall 2 with a screw 6, and the leaf spring 5 is pressed against the outer periphery of the leg 4 to connect the leg 4 to the bottom body. It is designed to be held in two positions: a position where it is tilted downward (shown by the dotted chain line in Figure 1) and a position where it is rotated more than 90 degrees from the bottom of the bottom body (shown by the solid line in Figure 1). .

ところが、上記の場合には板バネ５およびネジ

It was hot.

本考案は、かかる欠点に鑑みてなされたもの

提供することを目的とする。 The present invention has been developed in view of these drawbacks, and includes a guide wall integrally protruding from the lower surface of the container, and protrusions for holding the legs in two positions at the tip of the inner surface of the guide wall, while engaging with the protrusions. The side part of the leg that
By forming an inclined surface by slanting the leg width toward the back of the leg, the above-mentioned leaf spring can be omitted, reducing the number of parts and assembly man-hours, and eliminating the risk of rust. It is an object of the present invention to provide a leg structure for a container that prevents the container from remaining in rotational positions other than the second position.

設されている。 FIG. 2 and subsequent figures show an example of the leg structure of a container according to the present invention. Reference numeral 10 is a synthetic resin bottom body of, for example, a liquid heat-insulating container A, and the bottom surface of this bottom body 10 has three collages as in the conventional case. A letter-shaped support wall 11 is integrally provided in a protruding manner, and a support shaft 1 is inserted between opposing wall portions of this support wall 11.
2 is inserted. Furthermore, a pair of guide walls 13 having substantially the same height as the support wall 11 is protruded from the bottom surface of the bottom body 10 adjacent to the support wall 11 , and a cut is made between the support wall 11 and the guide wall 13 . A groove 15 is provided to divide both walls 11 and 13, giving bending elasticity to the guide wall 13. Furthermore, a protrusion 14 having a triangular cross section is provided protruding from the inner surface of the tip end of the guide wall 13 in the opposite direction.

参照、第２図中実線で示す。）。 16 is a leg made of synthetic resin, and this leg 16 is supported by a support shaft 12 inserted into the support wall 11 so as to be rotatable at a certain angle (for example, about 110 degrees). The leg 16 has a substantially U-shaped cross section, and a stepped cam-shaped side locking portion 17 is formed on the outer peripheral surface of the end on the support shaft 12 side. When this leg 16 is tilted toward the lower surface of the bottom body, the protrusion 14 of the guide wall 13 engages with the rear surface locking portion 18 on the back surface of the leg 16 (see FIG. 3,
It is shown by a dashed line in the figure. ), the legs 16 are fixed without wobbling, but when the legs 16 are rotated outward from the bottom surface of the bottom body by more than 90 degrees (for example, 110 degrees), the vicinity of the back surface locking portion 18 is attached to the support wall 11. The side locking portion 17 contacts the inner surface of the projection 14, and the side locking portion 17
The legs 16 are engaged with the right end in the figure, and the legs 16 are positioned in an open state. That is, the end surface 19 of the side locking portion 17 on the step side is formed to be inclined inward of the leg 16, and when the legs are opened, after the protrusion 14 is pushed out with the side surface of the leg 16, the guide The legs 16 in the open state are fixed by being inserted into the inclined end surface 19 by the elastic restoring force of the wall 13 (see FIG. 4, shown by solid lines in FIG. 2).

さらに、脚１６側面の上記突起１４と当接する

めが不安定な中間回動位置に脚１６が留まるのを
防いでいる。 Further, in the portion of the side surface of the leg 16 that comes into contact with the protrusion 14, there is an arcuate inclined surface 20 that is inclined so as to reduce the leg width from the side locking portion 17 toward the rear locking portion 18. When the legs are closed, the protrusion 14 is pushed out along the end surface 19, and the end surface 19
After overcoming and passing through, without adding any input,
The legs 16 are rotated to the closed leg position only by the elastic return force of the guide wall 13, thereby preventing the legs 16 from remaining in an unstable intermediate rotation position.

したがつて、上記構成の脚構造は脚１６を底体
下面側に倒した状態では支持壁１１の下面が底面

一方、脚１６を開いた状態では容器Ａを高い位置
で支持し、例えば下部に注ぎ口を有する液体容器
では、この注ぎ口を床面から離して内容液をコツ
プ等で受けることができるようにしている。 Therefore, in the leg structure having the above configuration, when the legs 16 are tilted toward the lower surface of the bottom body, the lower surface of the support wall 11 is in contact with the bottom surface, and while supporting the container A stably at a low position, the legs 16 are opened. In this state, the container A is supported at a high position, and for example, in the case of a liquid container having a spout at the bottom, the spout is moved away from the floor surface so that the liquid content can be received with a cup or the like.

以上の説明で明らかなように、本考案によれ

組立工数を削減できるとともに、錆の心配もなく
なり、耐久性は向上する。 As is clear from the above description, according to the present invention, a guide wall is integrally provided on the lower surface of the container, and protrusions for holding the legs in two positions are provided on the tip of the inner surface of the guide wall. Therefore, there is no need to use conventional leaf springs to hold the legs, which reduces the number of parts and assembly man-hours, eliminates the risk of rust, and improves durability.

また、上記突起と係合する脚側面部分を、脚背

故を防止することができる等の効果を有してい
る。 In addition, the leg side portion that engages with the protrusion is tilted toward the back of the leg to reduce the leg width, so the leg remains in an unstable intermediate rotation position other than the 2 open/close positions. When the container is supported by the legs, it is possible to prevent an accident in which one of the legs closes due to the weight of the container and the container accidentally falls over.
