Japanese Utility Model Publication No. 8-2156 (page 4, Fig. 1)

  A conventional packaging device for a ventilation fan or a ventilation fan mounting frame receives a compressive load or the like with an outer box or a buffer member housed in the outer box so that no direct load is applied to the ventilation fan or the ventilation fan mounting frame. For this reason, high-strength cardboard is used, the number of parts is large, the packaging material is bulky, and the storage efficiency is low. Many of the packaged ventilation fan mounting frames are difficult to stack and store and transport, and are easy to collapse.

  The present invention has been made in order to solve the above-described conventional problems, and the object of the present invention is to make the packaging load to the compression fan, simplify the packaging, reduce cost and store. It is to obtain a packaging device that can realize an improvement in efficiency, and to obtain a packaging device that can be stored and transported in a stacked manner.

Upon present invention to achieve the above object, a flange in the height direction of the end of a rectangular frame structure extend, constituting the packaging device of ventilating fan mounting frame mounting screw protrudes at the other end, the ventilating fan mounting On each of a pair of sides of a rectangular corrugated cardboard sheet having a plane area substantially equal to the projection plane of the frame, an elevation surface having a height corresponding to the thickness of the ventilation fan mounting frame and the flange of the ventilation fan mounting frame are viewed from above. A first flap comprising a protective surface to be covered and a fixed piece that is in close contact with the frame structure and bent inward is provided, and is superimposed on the cardboard sheet on each of the other pair of sides of the cardboard sheet. a holder surface that, formed at both ends of the holder surface bent in a Z shape, and the ventilation fan mounting frame the back of the flange of the ventilating fan mounting frame is received by the long upper surface than projecting dimension of the flange A holding surface for supporting the cardboard superposed with the previous SL holder surface on the sheet providing the second flap comprising a screw receiving piece for receiving the end of the mounting screw with the holder surface.

  According to the present invention, the ventilation fan mounting frame is placed on a cross-shaped corrugated cardboard sheet in which one type of flap is folded, and the other one type of flap is overlaid on the flange with a protective surface. It becomes a simple packaging form in which it is wound into a sleeve shape and the whole is bound by a binding material. A fixed piece is bent into the frame structure by pressure bonding, and the movement of the ventilation fan mounting frame in one horizontal direction is restricted. The movement in the other lateral direction is restricted by the upper surface portion of the Z-shaped holding surface. The compressive load is carried by the ventilation fan mounting frame itself, and is received by a double structure of the cardboard sheet and the holder surface. Therefore, the cost can be reduced and the storage efficiency can be improved. Since the flange is protected by the protective surface, a large number can be stacked and stored or transported.

  The packaging device of the present invention wraps a ventilation fan mounting frame in which a flange extends to one end of a rectangular frame structure and a mounting screw projects from the other end. Two types of flaps are provided on each of the four sides of the corrugated cardboard sheet having a plane area substantially equal to the projection plane of the ventilation fan mounting frame to form a cross-shaped sheet, and the sheet is packaged alone except for the binding material. One type of flaps are provided facing each other, an elevation corresponding to the thickness of the ventilation fan mounting frame, a protective surface covering the flange of the ventilation fan mounting frame from above, and crimped into the frame structure and bent inward Two fixed pieces on the left and right sides are connected by a cut line. Another type of flaps are also provided facing each other, a holder surface superimposed on the corrugated cardboard sheet, formed on both ends of this holder surface, bent to a Z shape and attached to the back of the frame structure of the ventilation fan mounting frame The holding surface that diagonally supports the height of the protrusion of the mounting screw and the screw receiving piece that is superimposed on the cardboard sheet together with the holder surface and receives the end of the mounting screw together with the holder surface are cut into a ruled line It is connected with the line. The upper surface portion of the holding surface is longer than the protruding dimension of the flange. The ventilation fan mounting frame is wound into a sleeve shape with this cross-shaped sheet, and the whole is bound with a binding material.

  According to this packaging device, the ventilation fan mounting frame is placed on a cross-shaped corrugated cardboard sheet in which one type of flap is folded, and the protective surface is overlaid on the other type of flap on the flange. Then, it is wound into a sleeve shape and becomes a simple packaging form in which the whole is bound by a binding material. The frame structure is pressure-bonded, and a fixed piece is bent inward in a stretched state, thereby restricting the movement of the ventilation fan mounting frame in one horizontal direction. The movement in the other lateral direction is restricted by the upper surface portion of the Z-shaped holding surface. The compressive load is carried by the ventilation fan mounting frame itself, in particular, by mounting screws, and is received so as not to penetrate through the triple structure of the cardboard sheet, the holder surface and the screw receiving piece. Therefore, the cost can be reduced and the storage efficiency can be improved. Since the flange is protected by the protective surface, a large number can be stacked and stored or transported.

Embodiment 1 FIG.
The present embodiment relates to a packaging device for packaging a ventilation fan mounting frame in which a flange extends to one end of a square frame structure and a mounting screw protrudes to the other end. 1 is a perspective view of a ventilation fan mounting frame, FIG. 2 is a sectional view of the ventilation fan mounting frame, FIG. 3 is a developed view of a cross-shaped sheet, FIG. 4 is a perspective view showing a form in the middle of packaging, and FIG. FIG. 6 is a perspective view of the packaging state, and FIG. 7 is a perspective view of the laminated packaging apparatus.

  As shown in FIGS. 1 and 2, the ventilation fan mounting frame 1 has a structure in which a flange 3 extends to one end of a rectangular frame structure 2 and mounting screws 4 protrude from four corners of the other end. As shown in FIG. 3, the packaging device is configured as a cross-shaped sheet by integrally providing two types of flaps 6, 7 on four sides of a corrugated cardboard sheet 5 having a flat area substantially equal to the projection plane of the ventilation fan mounting frame 1. ing. One type of the flaps 6 and 7 is provided to face each other, from an upright surface 8 corresponding to the thickness of the ventilation fan mounting frame 1, a protective surface 9 that covers the flange 3 of the ventilation fan mounting frame 1 from above, and from the flange 3 side. The left and right fixed pieces 10 that are crimped into the frame structure 2 and bent inward are connected by ruled lines and cut lines. A hole 11 is formed at the inner end of the cut line at the boundary between the fixed piece 10 and the protective surface 9 so as not to be broken during bending. Here, the direction of the corrugated cardboard of the cross-shaped sheet (the direction in which the corrugated wave runs) is the direction indicated by the arrow in FIG.

  Another type of the flaps 6 and 7 are also provided facing each other, and are formed on the holder surface 12 superimposed on the corrugated cardboard sheet 5 and formed on both ends of the holder surface 12 and bent in a Z shape to form the ventilation fan mounting frame 1. The rear surface of the frame structure 2 is received by the bent portion of the mounting screw 4 and the holding surface 13 that supports the height of the protruding portion of the mounting screw 4 obliquely is superimposed on the cardboard sheet 5 together with the holder surface 12. A screw receiving piece 14 that receives the end of 4 together with the holder surface 12 is connected by a ruled line and a cut line. The upper surface portion 15 of the holding surface 13 is longer than the protruding dimension of the flange 3. The ventilation fan mounting frame 1 is wound around this cross-shaped sheet in a sleeve shape as shown in FIGS. 5 and 6, and the whole is bound by a binding material 16.

  According to this packaging device, the ventilation fan mounting frame 1 is placed on the cross-shaped corrugated cardboard sheet 5 in which one type of flap 7 is folded, and the other type of flap 6 is placed on the flange 3. The protective surface 9 is overlaid and wound into a sleeve shape, and a simple packaging form in which the whole is bound by the binding material 16 is obtained. The frame structure 2 is crimped into the frame, and the fixed piece 10 is bent inwardly in a stretched state, so that the movement of the ventilation fan mounting frame 1 in one horizontal direction is restricted. The movement in the other lateral direction is restricted by the curved portion hitting the upper surface portion 15 of the Z-shaped holding surface 13 and the mounting screw 4. The compressive load is borne by the ventilation fan mounting frame 1 itself, in particular, the mounting screw 4 and is received so as not to penetrate through the triple structure of the cardboard sheet 5, the holder surface 12, and the screw receiving piece 14. The corrugated cardboard sheet 5 and the holder surface 12 have the same direction of corrugated cardboard, but are offset from the screw receiving piece 14 by 90 degrees. For this reason, it does not penetrate through the load applied to the mounting screw 4. The Z-shaped holding surface 13 performs a buffer function by elastic movement in the vertical direction. Accordingly, the cost can be reduced and the storage efficiency can be improved. Since the flange 3 is protected by the protective surface 9, a large number can be stacked and stored or transported as shown in FIG. For unpacking, if the binding material 16 is unwound, the form shown in FIG. 4 is obtained, and it can be easily performed in the manner of opening the package. Since the side of the ventilation fan mounting frame 1 appears to be exposed, the handling of the load becomes careful as a result.

  As shown in FIG. 4 and FIG. 5, the proof stress against the compressive load can be easily and remarkably improved by attaching the cardboard laminated core 17 that holds the back surface of the flange 3 to the holder surface 12. Further, the ventilation fan mounting frame 1 without the mounting screw 4 may be configured such that the flange 3 is received by the upper surface portion 15 of the holding surface 13 and the curved portion is applied to the frame structure 2. In this case, the screw receiving piece 14 is used. Can be deleted or deleted.
