Description

[Detailed description of the invention] [Industrial application field] This invention relates to a shock absorbing fixture for an electric fan.

[Conventional technology]

As shown in Figure 4, electric fans for general household use are as follows:
It consists of a blade cover A made of a metal net-like body, a motor part B to which the blade cover A is attached, and a base C having an upright shaft, and the packaging box 31 is made of cardboard.
It is stored and transported. A buffer fixture 32 is fitted inside the packaging box 31 to stop the movement of the blade cover A.

As shown in the developed view shown in FIG. 5, this conventional shock absorbing fixture 32 has a substantially elliptical shape for fitting a blade cover in the diagonal direction of the central part of a rectangular flat plate 34 having substantially the same shape as the top wall 33 of the packaging box. Through-holes 35 are provided, and side plates 37 that are erected during use are connected to the four side edges of the flat plate 34 via fold lines 36, and diagonal fold lines starting from the corners of the flat plate 34 are formed at both ends of each side plate 37. A connecting piece 39 provided with 38 is arranged in a row.

A rectangular front plate 41 that is erected during use is provided on one curved edge in the longitudinal direction of the approximately elliptical through hole 35 and protrudes inward through a fold line 40, and a fan handle is provided on the other curved edge. A shallow notch 42 into which the blade cover is fitted is provided, and small notches 43 into which the outer ring of the blade cover is fitted are provided at both ends of the through hole.

[The problem that the idea aims to solve]

However, this conventional shock absorbing fixture for electric fans has disadvantages in that the flat plate 34 is easily bent due to vibrations, inclinations, etc. during transportation or transfer, and the fit between the blade cover and the through hole 35 is likely to loosen. This caused the problem that the stored electric fan could get damaged.

This idea was made in view of the problems of the conventional ones, and its purpose is to prevent the electric fan from moving inside the packaging box by holding the motor part together with the blade cover, and to provide a shock-absorbing fixation. The present invention aims to provide a shock absorbing fixture for an electric fan with improved effectiveness.

[Means for Solving the Problems] In order to achieve the above object, the shock absorbing fixture for the electric fan in this invention consists of a flat plate having approximately the same shape as the top wall of the packaging box in which the electric fan is housed, and a blade cover for insertion therein. While forming a through hole, side plates are set up on each of the four edges, and vertical fold lines are provided at important points on one side plate.
A separation line is provided from the lower end of this vertical fold line to the free end along the lower edge of the side plate, and a part of the side plate is bent inward by the vertical fold line, and the lower end is brought into contact with the motor part of the electric fan. At the same time, the tip is locked with the nearest side plate.

[Effect]

In the fan shock absorbing fixture configured in this way, by bending a part of the side plate from the vertical fold line and folding it in (see Figure 2), the motor part of the fan can be firmly pressed down. movement can be completely prevented.

〔Example〕

Figures 1 to 3 show examples of this invention,
This buffer fixture is made of thick paper such as corrugated cardboard, and has a rectangular flat plate 1 having approximately the same shape as the top wall 33 of the packaging box 31. A generally oval through hole 2 for inserting the blade cover A is provided in the diagonal direction at the center of the rectangular flat plate 1. Side plates 4, which are erected during use, are connected to the four side edges of the flat plate 1 via fold lines 3, respectively.

In the through hole 2, a rectangular front plate 6 that is erected during use is bored inward through a fold line 5 on one curved edge in the longitudinal direction, and a shallow front plate 6 into which the handle of the electric fan is fitted is formed on the other curved edge. A notch 7 is provided, and small notches 8 are provided at both ends of the through hole 2 into which the outer ring of the blade cover is fitted.
is provided.

At both ends of each side plate 4, at three locations: a position facing the front plate 6 and a position facing both notches 8.
A rectangular connecting piece 10 having a diagonal fold line 9 starting from a corner of the flat plate 1 is provided in series.

Further, one of the side plates 4 facing the notch 7 is provided with a crease line 11 in the vertical direction when the side plate is erected at a position close to the connecting piece 10, and a free end extends from the lower end of this crease line 11 along the lower edge of the side plate. A side plate 1 for fixing a motor part, which is provided with a separation line 13 between the ends thereof, and has a contact part 12 whose lower end abuts on the motor part.
4 is formed.

The side plate 14 for fixing the motor part is swingable about the fold line 11 as a pivot, and has a rectangular extension part 1 at its free end.
5 are installed in a row, making the required length longer. Further, a concave curved edge is formed at the tip of the abutting portion 12 located at the center of the separation line 13, which prevents movement of the motor portion (see FIGS. 2 and 3).

Furthermore, a thin cut 1 is made at the tip of the side plate 14 for fixing the motor part along the edge, and the lower end is the opening when standing up.
6 is provided. Further, a thin cut 17 is provided at a key point of the other side plate 4 adjacent to the extension portion 15, and has an opening at the upper end when raised, which engages with the above-mentioned cut 16.

As shown in FIGS. 2 and 3, in the buffer fixture, each side plate 4 is made to stand up to form a shallow rectangular tray shape, and the side plate 14 for fixing the motor part is turned inward at an angle of 45 degrees from the fold line 11. Both cuts 16,
17 and lock it with the other side plate 4, insert it from the upper opening of the packaging box 31 containing the electric fan, and fit the blade cover A into the through hole 2, so that the abutting part 12 of the side plate for fixing the motor unit It is formed to fit into the motor section.

Note that the distance from the fold line 11 of the motor part fixing side plate 14 to the edge is approximately the same as the distance from the notch 17 of the other side plate 4 to the edge.

When using the fan buffer fixture of this invention, the side plates 4 are erected on the four sides of the flat plate 1, and the connecting pieces 10 are folded inward from the diagonal crease line 9 to form a shallow square tray. Fixing side plate 1
4 is bent and folded inward from the fold line 11, and both notches 16 and 17 are engaged and locked to be assembled.

When this buffer fixture is inserted through the upper opening of the packaging box containing the electric fan and the blade cover A is fitted into the through-hole 2, each side plate is tightly inscribed in the side wall of the packaging box, and the through-hole 2 and upright The blade cover part is held between the front plate 6 and the abutting part 12 of the side plate 14 for fixing the motor part firmly presses the motor part, which prevents the packaging box from vibrating during transportation, transshipment, etc. Even if the fan is tilted or tilted, the movement of the fan is blocked and damage can be prevented.

[Effect of idea]

This idea is structured as described above, so
This produces the following effects.

The contact part of the side plate for fixing the motor part contacts the motor part, and the movement of the motor part is completely prevented by the side plate for fixing the motor part in the vertical direction, so there is no wobbling due to the deflection of the flat plate as in the conventional case. This also prevents accidents such as damage to the electric fan due to loose fitting between the through hole and the blade cover.
