Description

[Detailed Description of the Invention] This invention relates to a cushioning material for storing and transporting an electric fan.

This kind of cushioning material mentioned above is required to be able to store the fan without adding bulk or rattling as much as possible, but conventional cushioning materials have only been designed to meet these requirements, and have been designed to accommodate the fan model. Its size and form were determined for each.

Therefore, different cushioning materials were provided for different sizes of guards in simple electric fans.

However, if you simply store a fan with a different guard size by making a unique cushioning material for it, the cushioning material itself will be expensive.

It is also true that changing the dimensions of the guard results in a lot of wasted cushioning material that becomes unusable.

The object of the present invention is to provide a versatile and economical fan storage cushioning material that can stably store both large and small guards.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

A cushioning material for storing electric fans as an application example of the present invention is made by assembling two identical molded products to store two types of electric fans.

First, the configuration of a single cushioning material 1 will be explained with reference to FIG.

As shown in the plan view of the cushioning material 1 in FIG.

A circular guard housing recess 5 is formed in the center of the cushioning material 1 so that the guard covering the fan blades 2 can be separated into a front guard 3 and a rear guard 4. Body accommodating portions 7 for accommodating the body 6 of the electric fan from which the blades 2 have been removed are arranged one by one and recessed in the vertical direction in FIG.

The guard housing recess 5 has a depth that can completely accommodate the front guard 3 and rear guard 4 of a large-sized fan with a large diameter when they are overlapped and closed. It comes into contact with each outer peripheral edge 9 of the front guard 3 and rear guard 4 in the shaped guard, and can restrain the front guard 3 and rear guard 4 from the sides, and is functionally a guard support surface that supports the guards. be.

The bottom surface of the guard housing recess 5 is not flat, but has a step between the center and the outer edge.

The step in the center is formed by forming a blade support surface 11 that is higher than the surrounding bottom surface from which a blade stopper 10 is vertically protruded for inserting the boss part of the blade 2 into the center and fixing the blade 2 there. This is due to the formation of a guard receiving surface 12 for receiving the joining surface of the front guard 3 or rear guard 4 of the outer edge.
It is at almost the same level.

This guard receiving surface 12 has three protrusions 13 that locally protrude slightly inward (toward the center) at equal intervals, and the upper part of the protruding end of each protrusion 13 has a support protrusion that extends upward. 14 stands out.

The three support protrusions 14 of the protrusion 13 are all located on the same circumference, and the front guard 3 or rear guard 4 of the guard is one step smaller than the guard that contacts the guard support surface (peripheral side wall 8) described above. The rear guard 4 and the front guard 3 can be restrained by coming into contact with a part of the inner periphery of one of them from the inside.

ly- and for this small guard each protrusion 1
The upper surface of the front guard 3 serves as a receiving surface for the small guard on which the front guard 3 receives the joining surface of one of the rear guards 4 (the lower side when stacked).

The left and right body accommodating parts 1 that house the body 6 of the electric fan have a profile corresponding to the body 6 so that one side (the left side in Fig. 1) can accommodate the body 6 forward, and the other side can accommodate the body 6 facing backward. It is formed as a recess.

However, in this example, two sets of the same cushioning material 1 are used to store two types of electric fans, so each body housing section 1 is deep enough to accommodate half of each body 6.

Furthermore, the reason why one body accommodating part T is divided into one for forward facing and one for backward facing is also because of the joining of the same type of cushioning material 1.

This is nothing but a configuration for rationally accommodating two types of aircraft bodies 6.

Therefore, in the case of a device that stores a fan for a machine, for example, the number of body housing parts 1 may be one, and the depth thereof is 6
It will fit almost completely and form a vine.

However, even in this case, the guard housing recess 5 is the same as described above.

The above-described cushioning material 1 can accommodate two large and small guards depending on the structure of the guard accommodating recess 5 thereof.

Then, using this cushioning material in a bonded state,
J: As shown in Figure 2, two types of electric fans can be stored, and in that case, it is also possible to store one set with a large guard and one with a small guard.

In other words, a large guard fan has a fuselage 6, blades 2,
After disassembling into the front guard 3 and rear guard 4, and storing the fuselage 6 in the fuselage accommodating part 7, the blade 2 is passed through the blade stop 10 in the center of the guard accommodating recess 5 and received on the blade support surface 11, The front guard 3 and the rear guard 4 are fitted over each other and placed in the guard release recess 5 in a face down state.

At this time, in the case of a large guard, the front guard 3 or the rear guard 4 as shown in the right half of Figure 2.
One joint surface of the guard is received in contact with the guard receiving surface 12, and the outer peripheral edge 9 of the front guard 3 and rear guard 4 is in contact with the peripheral side wall 8 of the guard housing recess 5, thereby being restrained and stabilized. The state is maintained.

Then, if some of the other electric fans are placed in another cushioning material 1 in the same way, these two cushioning materials 1 are joined facing each other, and they are stored in the outer box 15 in this state. The two types of electric fans can be easily stored and transported together.

Note that 16 in the figure is a band interposed between the guard and the blade 2.

Even in the case of a small-sized guard, the operation for storing the cushioning material 1 is the same as that for the above-mentioned large-sized guard.

However, in the case of a small guard, the working surface of the guard housing recess 5 changes as follows.

In the case of a small guard, as shown by the left half of Figure 2.

The upper surfaces of the three protrusions 13 receive the joint surfaces of either the front guard 3 or the rear guard 5.

The front guard 3 or the rear guard 4 is restrained by three support protrusions 14 fitted to the inner periphery of either guard.

In other words, this cushioning material 1 can be used to store both large and small electric fans with guards.

The support protrusion 14 may have a continuous ring shape or may have a discontinuous protrusion structure as in the above embodiment.

As is clear from the above description of the embodiments.

The shock absorbing material for storing a fan of the present invention separates a large guard with a large diameter into a front guard and a rear guard, and places a small guard with a small diameter in a storage recess in which the large guard with a large diameter is separated into a front guard and a rear guard. A supporting protrusion is provided that abuts against the inner periphery of the guard to restrain and support the guard, and a large guard is restrained by the circumferential side wall of the accommodation recess, and a small guard is restrained by a support protrusion in the accommodation recess. Moreover, the blades are held by a blade stopper provided at the center of the accommodation recess.

Therefore, it can be used as a cushioning material for storing both large and small guard fans.

Therefore, one type of cushioning material can be used in common with two types of electric fans, which reduces the need for molding the cushioning material, making it cheaper in terms of cost, and it can also be made unusable by changing the dimensions of the guard. Therefore, it is possible to eliminate waste related to cushioning materials.

In particular, since the blade can be housed together with the guard in the housing recess that accommodates the guard, there is an advantage that a compact housing form with a small plane area can be obtained.
