Japanese Kokai (Laid Open) Patent No. H10-95429
The above-noted packing apparatus and casing apparatus are configured to be re-used for a predetermined times and thus can reduce refusal materials. However, the above-noted packing apparatus and casing apparatus do not have enough structures to further advance economizing and recycling, because the packing apparatus and the casing apparatus are made of a number of different materials and are weakly made from thin synthetic resin. On the other hand, the above shipping and storing apparatus, which fastens the electrical product on the pallet, are made of a fewer number of materials and are firmly made form thick synthetic resin or metal. Thus, this type of apparatus has sufficient endurance to be re-used for a longer period of time and is better than the above-noted packing apparatus and casing apparatus with respect to the advance of economizing and recycling.
However, the above shipping and storing apparatus has the following problem. It is difficult for the shipping and storing apparatus to adapt an electrical product with a different size or shape form a predetermined size or shape. Therefore, when there are many types of electrical products regarding sizes or shapes, many types of the shipping and storing apparatuses have to be prepared for each type of electrical products. This causes costs to rise and gives bad effects to economizing and recycling. Even if the shipping and storing apparatus is made to be re-used, the shipping and storing apparatus can not adapt many types of electrical products with different sizes or shapes. Thus, when a new type of the electrical product has a different size or shape from a former product, the shipping and storing apparatus can not be used for the new type of the electrical product. Therefore, the shipping and storing apparatus can be re-used only for a limited time and can not advance economizing and recycling over a long period of time.

SUMMARY OF THE INVENTION

The invention puts forth a carrier apparatus that resolves the shortcomings noted in the related art; the main purpose of the invention being to provide a carrier apparatus that easily adapts to business machines of various sizes and shapes, and that encourages recycling and the conservation of raw materials.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

First Embodiment

Figure 1 is a perspective view of the first embodiment of the carrier apparatus of the present invention. In this embodiment, the carrier apparatus comprises platform 2 that includes support surface 1 on which business machine 'A' (hereafter referred to as "product 'A"') is placed, and clamping fixtures 3 that are able to secure product 'A' to platform 2 at the variable positions through attachment structures formed on support surface 1. Groove 6, to which bolt 5 (fastening device) attaches, is formed on platform 2, therefore clamping fixture 3 may attach to platform 2 at any position within the length of groove 6.
Like a common loading pallet, platform 2 includes upper board member 11, lower board member 12, post parts 13 that connect the upper and lower board members, and a space between upper and lower board members 11 and 12 for the insertion of the fork of a freight- handling vehicle such as a fork lift or pallet truck. Platform 2 is made from an aluminum alloy to provide both strength and light weight.
Upper board member 11, which comprises the upper part of platform 2, includes support surface 1 on which product 'A' is placed, and rubber block (shock absorbing member) 15 that inserts between support surface 1 and product 'A' in order to prevent product 'A' form having damages that could result from vibration and shocks encountered during shipping.
Figure 2 is a cross section illustrating a detailed view of clamping fixture 3 and showing plane figure cut along the groove 6. Clamping fixture 3 comprises clamp plate 24. Clamp plate 24 comprises clamp flange 23 (clamping member). Clamp flange 23 engages clamp orifice 22. Clamp orifice 22 is provided on frame member (chassis) 21 and exposes a lower surface of the business machine. Clamp orifice 22 comprises a hole and a hollow. Clamping fixture 3 also comprises a fastening device including bolt 5 and nut 25. The fastening device clamp secures plate 24 to platform 2.
Clamp plate 24 comprises horizontal part 27 and vertical part 28. Horizontal part 27 locates along support surface 1 of platform 2. Vertical part 28 vertically extends upward from one end of horizontal part 27. Clamp plate 24 is formed by cutting sheet metal in a predetermined shape and being bent. Horizontal part 27 comprises a thru-hole for the insertion of bolt 5. Clamp flange 23 horizontally protrudes from the upper end of vertical part 28. When Clamp flange 23 is inserted upward through clamp orifice 22 of the business machine and is slid horizontally over the edge of clamp orifice 22 until clamp flange engages an edge of clamp orifice 22, frame member 21 of the business machine is fastened on support surface 1 of platform 2. 31 is a caster of the business machine.
Figure 3 is a cross section illustrating a detailed view of clamping fixture 3 and showing plane figure cut in a crossing direction of the groove 6. Bolt 5 is inserted through the open end of groove 6. The open end of groove 6 is formed to a width narrower than the head of bolt 5, so the head of bolt 5 engages shoulder part 33 of the open end. On the other hand, the floor part of groove 6 is formed to a width that does not restrict the movement of the head of bolt 5. Groove 6 has a inverted T-shape cross section along the entire length of the groove.
Therefore, when bolt 5 and nut 25 are mutually loosened, clamping fixture can be allowed to slide along groove 6. Thus, clamp plate 24 can be set at a position where clamp flange 23 of clamp plate 24 can properly engage the business machine. After that, bolt 5 is tightened on nut 25, so clamps shoulder part 33 of groove 6 is sandwiched between the head of bolt 5 and horizontal part 27 of clamp plate 24. Thereby clamp plate 24 is strongly secured against platform 2.
Figure 4 is a plan view of the carrier apparatus shown in Figure 1. Each groove 6 extends from the external edge toward the center of support surface 1. In this embodiment, in order to adequately secure product 'A' of a square case, grooves 6 extend in a straight line from the comers of square-shaped support surface 1 toward the center, and each of four grooves 6 is located at each of the four comers of platform 2. Further, four grooves 6 are also provided on platform 2, and each of four clamping fixture 3 is arranged on each of four grooves 6. Thus, product 'A' is secured to platform 2 at each of the four comers of product 'A' by the respective clamping fixture 3.
Because the clamping position of each clamping fixture 3 may be located at any point along its respective groove 6, clamping fixtures 3 can be easily positioned to accommodate either product 'A' or 'B' which are of different size and shape. Also, either product 'A' or product 'B' is secured in a stable condition for shipment and storage because either product 'A' or product 'B' is fastened at the center of support surface 1.
Figure 5 is a cross sectional view of the carrier apparatus shown in Figure 1. Support surface 1 is formed as a flat plane on the upper surface of upper board member 11. Casters 3 1 are attached to the bottom part of product 'A' and are able to roll on support surface 1. Thus, product 'A' can easily move to any position on support surface 1. Furthermore, when a ramp (not shown in the drawings) is set next to platform 2, product 'A' can be easily moved and loaded from the outside of platform 2 onto support surface 1 of platform 2.
In order to reduce weight, void spaces 32 may be formed by the removal of material from lower board member 12. Lower board member 12 has no functional relationship to support surface 1 on which product 'A' may be moved. Thus, void spaces 32 will have no adverse effect on the movement of product 'A' on support surface 1.
The carrier apparatus described by the invention is constructed of platform 2, clamping fixtures 3, and rubber blocks 15. The carrier apparatus is assembled form a few components, but is robust. The carrier apparatus offers durability that allows it to be used repeatedly over a long period of time, is able to easily adapt to differently sized and shaped products, and encourages recycling and the conservation of raw materials. Moreover, product 'A' is loaded onto platform 2, as previously noted, and then is temporarily lifted. After that, clamp flange 23 of clamping fixture 3 can be placed into orifice 22 on the lower surface of product 'A' (see Figure 2), and rubber block 15 can be placed between support surface 1 and the lower surface of product'A'.

Second Embodiment

Figure 6 is a perspective view illustrating a second embodiment of the carier apparatus of the present invention. In this second embodiment, product 'A' is placed on support surface 41 of platform 42. A plurality of clamping holes 43 are arranged on platform 42. The plurality of clamping holes can engage bolts 5 of clamping fixture 3. Thereby, a location, where product 'A' is clamped to platform 42, can be adjustable.
Furthermore, in this second embodiment, platform 42 includes base part 51 in which void spaces are provided for the insertion of a loading vehicle fork. Platform 42 also comprises load board 52 which is located above base part 51 and whose upper side is structured as support surface 41. Platform 42 further contains rubber piece (shock absorbing member) 53 which is placed between load board 52 and base part 51 to prevent product 'A' form receiving damage by absorbing vibrations and shocks encountered during shipping.
Figure 7 provides a plan view of the carrier apparatus shown in Figure 6. Multiple clamping holes 43 are arranged in a line extending from the edge of support surface 41 toward the center. In this embodiment, there are four groups of clamping holes 43, each group extending inward in linear alignment from each of the four comers toward the center of support surface 41. Each of four clamping fixtures 3 is, in the manner as noted in the previous embodiment, secured to one of the holes in each of the four groups of holes in order to clamp the four comers of product'A' to platform 42.
At this time, one of the holes from each group of clamping holes 43 is selected as the hole to which clamping fixture 3 will be attached. Thus, the attachment position of clamping fixture 3 can be gradually selected at one of multiple positions. Through this mechanism, the attachment structure is able to accommodate differently sized and shaped products 'A'. Moreover, product 'A' is shipped and stored in a stable condition because product 'A' is secured at the center of support surface 41. Compared to the previously noted attachment structure, although the attachment position of this structure is more limited, this structure provides the advantage of more securely attaching product'A' to support surface 41.
Figure 8 is a cross sectional view of the embodiment shown in Figure 6. Load board 52 is a flat structure that incorporates support surface 41 so that casters 31 of product 'A' can roll on support surface 41. Like the previous embodiment, a operation, in which product 'A' is loaded and positioned on support surface 41, is made easier because product 'A' can be easily moved on support surface 41.
Base part 51 includes upper board member 55, lower board member 56, and post parts 57 which are located between upper and lower board members 55 and 56. Void spaces 61 and 62 are formed within upper and lower board members 55 and 56 to reduce weight of the carrier apparatus, but void spaces 61 and 62 are formed not to interfere with the movement of product 'A' on support surface 41.
Load board 52 is made of aluminum alloy plate, and base part 51 is made of synthetic resin. Therefore, load board 52 is rigid enough to adequately support product 'A', and the entire structure is designed to be light in weight. Compared to the previous embodiments, this structure requires a few more components, but the use of thickly formed synthetic resin and metal components provides for a durable structure that can be repeatedly used over an extended period of time. Thus, this structure can promote recycling and the conservation of raw materials.
Figure 9 is a cross sectional view of the rubber piece (shown in Figure 6) in an installed condition. Holes 65 and 66 are respectively provided in load board 52 and rubber piece 53. Clamp bolt 64 is inserted into holes 65 and 66. Clamp bolt 64 serves as a connecting member there between. With clamp bolt 64 inserted to holes 65 and 66, clamp bolt 64 is tightened into threaded hole 67 of base part 51. Rubber piece 53 is compressed between load board 52 and base part 51. Thereby, rubber piece 53, load board 52 and base part 51 are connected with each other. In this condition, because rubber piece 53 is elastically deformed, rubber piece 53 can -absorb vibration and shock applied to base part 51.

Third Embodiment

Figure 10 is a perspective view of a third embodiment of the carrier apparatus of the present invention. This third embodiment comprises platform 2 and clamping fixture 3 shown in the first embodiment illustrated in Figure 1. The third embodiment further comprises protective cover 71 which covers product 'A'. Protective cover 71 protects product 'A', which is installed on support surface 1 of platform 2, from dirt and rain.
Protective cover 71 is a bag-like structure covering five of the six surfaces of product 'A' (the lower surface is not covered). Protective cover 71 includes separating part 72 that may be joined by fastening part 73. Separating part 72 extends vertically along the approximate complete height of cover 71. Also, tie string (constricting device) 75 is provided at edge part 74 at the lower end of protective cover 71 within the hem of the bag-like structure. Tie string 75 may be tightened to constrict the lower opening of protective cover 71 as a method of securing cover 71 to product 'A'. Protective cover 71 can prevent dirt and rain from invading the inside of protective cover 71.
Figure 11 is a cross section of the protective cover shown in Figure 10. Protective cover 71 is made from a sheet material in which shock absorbing layer 81, which is made from a synthetic foam resin such as Mirror Mat or the like, is sandwiched between cover layers 82 and 83, which is made from polyethylene. Protective cover 71 is thus able to protect the product from shock during transport, and can be used repeatedly for an extended period of time due to its strong and durable construction.

Fourth Embodiment

Figure 12 is a perspective view of a fourth embodiment of the carrier apparatus of the present invention. This embodiment comprises clamping fixture 3 and platform 102 that carries product 'A' on support surface 1. This embodiment also incorporates framework 103. Framework 103 allows platform 102, on which product 'A' is secured, to be stacked upon another platform 102, on which another product 'A' is secured. Framework 103 is constructed of four gate-like frame members 111 through 114. Frame members 111 through 114 are erected on platform 102 to form framework 103. Framework 103 surrounds product 'A' on support surface 101.
Platform 102 is generally similar to platform 2 of the first embodiment shown in Figure 1. Platform 102 comprises blind holes 116. Each of blind holes 116 is provided at a comer of support surface 101 to be attached to framework 103. The bottom ends of taller gate- like frame members 111 and 113 are inserted into blind holes 116 to be secured to platform 102. The shorter gate- like frame members 112 and 114 are secured to frame members 111 and 113 by threaded fasteners.
In order to aid handling, each gate-like frame member 111 through 114 includes grip member 118. Grip member 118 is configured horizontally at the approximate midpoint of each of the frame members 111 through 114. Frame members 111 through 114 are fabricated from metal pipes. Surfaces of the metal pipes are covered by a layer of synthetic resin.
Two stacking channels 121 are formed within the lower side of platform 102. Stacking channels 121 can join the top parts of frame members 111 and 113 of another carrier apparatus when a carrier apparatus is stacked upon the another carrier apparatus. Stacking channels 121 are formed along the edges of platform 102 where frame members 112 and 114 are located. Stacking channels 121 also have openings at the edges of platform 102 where frame members 111 and 113 are located.
Figure 13 is a side view showing two carrier apparatuses stacked one upon the other. The top parts of frame members 111 and 113 of the lower carrier apparatus are inserted to stacking channels 121 on the bottom of platform 102 of the upper carrier apparatus. Thus, the upper carrier apparatus is stacked on the lower carrier apparatus and is oriented 90-degrees with respect to the lower carrier apparatus. Thereby, the upper carrier apparatus is stabilized on the lower carrier apparatus. Moreover, the upper carrier apparatus can be stacked on the lower carrier apparatus without contacting with product 'A' on the lower platform 102. Therefore, the weight of the upper carrier apparatus does not influence the product 'A' located placed on the lower carrier apparatus.
