Description

[Detailed description of the invention] [Industrial application field] The invention makes it possible to quickly and easily raise and store an existing container to a desired height according to the size and height of the stored items. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for raising containers, which can be efficiently and economically used and can be stacked safely and reliably in a plurality of stages.

[Prior art] Without increasing the storage container according to the width of the stored item every time, the height of the stored item should be raised according to the length or height of the stored item in order to increase the use efficiency and the range of use of the existing container. For example, as a raised part that can be stacked with high efficiency in a plurality of stages, a corner part having a diameter corresponding to the height of the stored material is attached to only the four corners of the container by means such as screwing. Alternatively, there is a method in which an integral frame-shaped frame having a height corresponding to a desired height of the stored items is fixedly attached to the entire peripheral edge of the container.

[Problem to be Solved by the Invention] However, in the method of screwing the bulking member only at the four corners of the container, the bulked container is multi-staged without any trouble according to the height of the storage material such as the printed circuit board. Of course, it is possible to stack, but when the stacking members are attached only at the four corners, when stacking, there is a space on each side of the upper container except for the four corners of the lower container. In this space, there is a need to completely prevent the attachment of dust such as a printed circuit board due to the entry of dust and the like, and to the storage of food and the like which must minimize the attachment of foreign matter such as dust for sanitation. Thus, such bulking members have never been satisfactory.

In addition, since this kind of corner-raising corner parts is screwed to the container, it requires a great deal of labor and time to attach and remove it. Is usually used at the same height.

That is, there has been no contrivance that it can be quickly and easily attached to and detached from the container body, and that it should be securely and firmly integrated with the container body during the installation.

In the present invention, mounting and dismounting are performed easily and quickly, and during mounting, they are firmly and firmly integrated with the container, and there is no risk of dust entering the container. It is an object of the present invention to provide an extremely convenient container lifting frame that can be safely and hygienically conveyed and stored.

[Means for Solving the Problems] The above-mentioned problem is solved in a bulk-lifting frame main body of a synthetic resin container having a flange portion at an upper edge portion and a lower portion, and a flange portion at an upper edge portion of the frame main body is provided with an interval. A plurality of engaging holes are drilled, and a plurality of mountain-shaped stepped portions bent toward the upper portion of the frame main body at intervals are formed in the flange portion of the lower portion of the frame main body,
Further, the concave bottom portion of the mountain-shaped step portion is inserted into an engagement hole formed in an upper edge portion of the container body located below or an engagement hole formed in a flange portion of the upper edge portion of the frame body. Along with projecting two elastically resilient locking claw members having flexibility and having a locking projection at the tip end thereof,
The width between both outer ends of the locking projection at the tip of the locking claw member is formed to be larger than the diameter of the engaging hole and the flange engaging hole at the upper edge of the container body. It is solved by the feature of the container raising frame.

[Embodiment] An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 is a front view of the frame raising frame of the present invention, FIG. 2 is a right side view, FIG. 3 is a plan view, and FIG. 4 is AA in FIG.
FIG.

In the figure, reference numeral 1 denotes a body frame of the present invention, which is made of a synthetic resin material.

Reference numeral 2 denotes a flange formed on the upper edge portion of the raising frame body 1, and a plurality of engaging holes 3 are formed in the flange portion at regular intervals.

Reference numeral 4 denotes a flange portion formed in a lower portion of the frame raising frame main body 1. In this flange portion 4, a plurality of trapezoidal steps 4a are formed upward at intervals.

Reference numerals 5 and 5 denote two elastic claw members which are protruded from the concave bottom of the trapezoidal stepped portion 4a and have elasticity and are capable of returning.

The locking claw members 5, 5 are formed in the above-described upper edge portion and are inserted into and engaged with the engagement holes 3, and have locking portions having tapered portions which are inclined upward and outward at their tip portions. Department
5a, 5a are protruded, and the width between the outer ends of the locking protrusions 5a, 5a is formed to be larger than the diameter of the engagement hole 3.

In the present embodiment, the flange portion 2 of the upper edge portion is formed with three engaging holes 3 on the long side and two on the short side, respectively, for a total of ten engaging holes 3. Similarly, there are ten locking claw members 5, 5 protruding at positions corresponding to 3, but it is needless to say that the number is not limited to this.

Further, the tip positions of the locking claw members 5, 5 are set so as to be located slightly above the lower edge portion of the bulk raising frame body 1.

In the above configuration, when raising the container,
As shown in FIG. 6 and FIG. 6, an engagement hole 8 formed in a flange portion 7 on the upper edge of the container body 6 or an engagement hole 3 formed in a flange portion 2 of the bulking frame body 1 located below. Then, if the two locking claw members 5, 5 are pushed in, the locking protrusions 5a, 5a at the tips of the plurality of locking claw members are formed with a tapered portion. While the distance between the members 5,5 is narrowing, it is smoothly inserted into each of the engagement holes 3 (8) with one touch, and after the insertion is completed, the two locking claw members 5,5 return elastically. The locking step portions 5a, 5a at the tips are securely and firmly engaged and fixed to the engaging holes 3 (8).

In particular, in the present invention, the two locking claw members 5, 5 protrude from the trapezoidal stepped portion 4a concave bottom portion, and dare to take its height, so that the elastic return force of the claw is strong and strong. An engaged state can be obtained.

When removing the locking claw member, as shown in FIG.
Since there is sufficient clearance between the reinforcing ribs located on both sides of the engaging hole and the locking step engaging with the engaging hole, the engaged state can be easily released.

That is, as shown in FIG. 6, the frame raising frame 1 of the present invention is engaged with the engaging hole 8 formed in the upper edge flange portion 7 of the container body 6 according to the size and height of the stored items. As shown in FIG. 7, a plurality of bulking frames 1 can be used to freely bulk up to a desired height in a plurality of stages according to the stored items, as shown in FIG.

[Effects of the Invention] According to the present invention, the container can be lifted to a desired height according to the size and height of the stored items. It is extremely economical because there is no need to purchase a container, and the use efficiency of the existing container is increased and the range of use is expanded. In particular, by providing two locking claw members protruding from the concave bottom of the mountain-shaped step and taking the height of the locking claw members, the elastic return force of the claw is strong and a strong engagement state is obtained. be able to.

In addition, unlike the conventional containers that can be lifted, it can be done quickly and easily with one touch, and there is no unstable connection state such as a gap or swing after the lifting. It is possible to maintain a reliable and strong connection state semipermanently. Of course, when returning to the original container, the engaged state can be quickly and easily released.
