Abstract

A platform-type shelf includes at least two lengthways lattice beams, at least two transverse lattice beams, at least two lengthways frame beams, and at least two transverse frame beams. Each lattice beam defines downward engaging grooves and upward engaging grooves. The lengthways lattice beams and the transverse lattice beams can be vertically snapped one other via a weaving technique. Each end of the frame beam has an outer tenon and an inner tenon, and the outer tenons of the two ends of the frame beam and the inner tenons thereof respectively have contrary locations in up-down direction. The outer tenons and the inner tenons of two adjacent frame beams are respectively engaged in a fastening manner. Thereby, the lattice-like platform-type shelf can be formed so as to entirely enhance its connecting force and supporting force, and to facilitate various derivative applications thereof.

Description

BACKGROUND

1. Field of the Invention
The present invention relates to a platform-type shelf and, more particularly, to a platform-type shelf assembled with lattice beams and an assembling method thereof. The platform-type shelf can be used as articles such as table, chair, bed set, worktable, trestle, pallet, padding plate, shelf and so on.
2. Description of the Prior Art
A conventional board or table for supporting weight is generally formed of a platform-type faceplate and supporting lattice beams. The board or table is a platform-type shelf such as, for example, a pallet for loading and unloading, a padding plate, a table, a chair, a bed set, a worktable etc. A main body of the platform-type shelf for directly supporting weight has been gradually changed to the supporting lattice beams instead of the faceplate. However, because lengthways lattice beams and transverse lattice beams both are columns with comparative thickness and width, they are generally engaged together using single-direction engaging structures (e.g., engaging grooves) formed thereon. Such arrangement results in that the lengthways lattice beams and the transverse lattice beams cannot generate a stable connecting force therebetween. When an outside force in a certain direction is accidentally exerted to the platform-type shelf, it is readily distorted or loosed. Also, if the engaging structures are not accurately machined, the engagement therebetween may need adhesive to increase the connecting force. Further, frame beams of the platform-type shelf need to be fixed by angle bars or nails at theirs meeting corners. Thus, such manufacturing and assembling process is relatively fussy and obviously cannot fully achieve the economical benefit of manufacture. Therefore, it is an important direction to develop and design the lattice beams of such platform-type shelf and to make theirs structural connecting strength can facilitate the use of paper material so that such disused platform-type shelf is more easy to be recovered, burned down or refashioned.
What is needed, therefore, is an improved platform-type shelf with a strengthened structure, a convenient performance and an economical performance.

DETAILED DESCRIPTION

Reference will now be made to the figures to describe the present invention in detail.
Referring to FIGS. 1 to 4, a platform-type shelf in accordance with a first embodiment of the present invention is shown. The platform-type shelf includes a central lattice beam group A, a locking lattice beam group B, and a frame beam group C. The central lattice beam group A includes two lengthways lattice beams 11 and 13, and two transverse lattice beams 12 and 14, which together form a central basic structure via a weaving technique. The central basic structure is a small pane as shown in FIG. 2. Also referring to the central lattice beam group A shown in FIG. 2, the lattice beams 11, 13, 12 and 14 define downward first engaging grooves 114, 134, 124 and 144 and upward first engaging groove 115, 135, 125 and 145, respectively. The terms “downward” and “upward” mean positional relationships between the grooves and the lattice beams (e.g., the term “downward” mean that the first engaging groove 114 is under the lattice beam 11). The downward first engaging grooves 114, 134, 124 and 144 and the upward first engaging groove 115, 135, 125 and 145 are configured for being vertically snapped one other, respectively. Further, the lattice beams 11, 13, 12 and 14 define downward second engaging grooves 113, 133, 123 and 143 and upward second engaging grooves 116, 136, 126 and 146, respectively. The downward second engaging grooves 113, 133, 123 and 143 and the upward second engaging grooves 116, 136, 126 and 146 are configured for being vertically snapped with the locking lattice beam group B. Furthermore, the lattice beams 11, 13, 12 and 14 define upward end engaging grooves 111, 131, 121 and 141 and downward end engaging grooves 117, 137, 127 and 147, respectively. The end engaging grooves 111, 131, 121 and 141 and the end engaging grooves 117, 137, 127 and 147 are configured for being vertically snapped with the frame beam group C, respectively. The end engaging grooves 111, 131, 121 and 141 are respectively defined by tenons 112, 132, 122 and 142, and the end engaging grooves 117, 137, 127 and 147 are respectively defined by tenons 118, 138, 128 and 148. In assembly, any lattice beam of the central lattice beam group A utilizes its first engaging groove to snap with the different-direction first engaging groove of the adjacent one of the central lattice beam group A so that the lattice beams are vertically snapped one other (e.g., the first engaging groove 115 and the first engaging grooves 124 shown in FIG. 2, the rest may be deduced by analogy). Then, each second engaging groove and each different-direction second engaging groove snap with the locking lattice beam group B. Further, each end engaging groove and each different-direction end engaging groove snap with the frame beam group C.
Referring to FIG. 3, the locking lattice beam group B includes two lengthways lattice beams 21 and 23, and two transverse lattice beams 22 and 24. The lattice beams 21, 23, 22 and 24 define downward first engaging grooves 214, 234, 224 and 244 and upward first engaging grooves 215, 235, 225 and 245, respectively. The downward first engaging grooves 214, 234, 224 and 244 and the upward first engaging grooves 215, 235, 225 and 245 are configured for being vertically snapped with the central lattice beam group A one another. Further, the lattice beams 21, 23, 22 and 24 define upward second engaging grooves 213, 233, 223 and 243 and downward second engaging grooves 216, 236, 226 and 246, respectively. The upward second engaging grooves 213, 233, 223 and 243 and the downward second engaging grooves 216, 236, 226 and 246 are configured for being vertically snapped one other. Furthermore, the lattice beams 21, 23, 22 and 24 define downward end engaging grooves 211, 231, 221 and 241 and upward end engaging grooves 217, 237, 227 and 247, respectively. The downward end engaging grooves 211, 231, 221 and 241 and the upward end engaging grooves 217, 237, 227 and 247 are configured for being vertically snapped with the frame beam group C one other. The downward end engaging grooves 211, 231, 221 and 241 are respectively defined by tenons 212, 232, 222 and 242, and the upward end engaging grooves 217, 237, 227 and 247 are respectively defined by tenons 218, 238, 228, 248. The assembled locking lattice beam group B can form a big pane so as to surround and engage the small pane of the assembled central lattice beam group A and to form a very firm pane body.
Referring to FIG. 6, the frame beam group C includes two lengthways frame beams 31 and 33, and two transverse frame beams 32 and 34. The frame beams 31, 33, 32 and 34 define upward mortise grooves 314, 334, 324 and 344, and downward mortise grooves 315, 335, 325 and 345, respectively. The upward mortise grooves 314, 334, 324 and 344 and the downward mortise grooves 315, 335, 325 and 345 are configured for being vertically snapped with the central lattice beam group A one other. Further, the frame beams 31, 33, 32 and 34 define downward mortise grooves 313, 333, 323 and 343 and upward mortise grooves 316, 336, 326 and 346, respectively. The downward mortise grooves 313, 333, 323 and 343 and the upward mortise grooves 316, 336, 326 and 346 are configured for being vertically snapped with the locking lattice beam group B one other. Furthermore, ends of the frame beams 31, 33, 32 and 34 are configured as double engaging structures (i.e., complex engaging grooves) and include outer tenons 312/318, 332/338, 322/328 and 342/348, and inner tenons 319/317, 339/337, 329/327 and 349/347. Each pair of the outer tenons 312/318, 332/338, 322/328 and 342/348 (such as the pair of outer tenons 312/318) is formed at two ends of the corresponding one of the frame beams 31, 33, 32 and 34, and has contrary locations in up-down direction (e.g., the outer tenon 312 is in an upper location, and the outer tenon 318 is in a lower location). Each pair of the inner tenons 319/317, 339/337, 329/327 and 349/347 (such as the pair of inner tenons 319/317) is formed at two ends of the corresponding one of the frame beams 31, 33, 32 and 34, and has contrary locations in up-down direction (e.g., the inner tenon 319 is in a lower location, and the inner tenon 317 is in an upper location). The outer tenons 312 and 318 are formed by first removing half of a partial inner side (a direction facing to the central lattice beam group A) in width, then removing half of a lower portion, an upper portion in thickness, respectively. The inner tenons 319 and 317 are sequentially formed by removing half of the lower portion and the upper portion of the partial inner side in thickness, respectively. Also, the outer tenons and the inner tenons of the adjacent frame beams have contrary locations in up-down direction (such as 312/348 and 319/347). After the central lattice beam group A and the locking lattice beam group B are assembled in a weaved manner, the frame beam group C is assembled with the central lattice beam group A and the locking lattice beam group B in a manner of pushing from outside to inside. Because the outer tenons and the inner tenons of the frame beams are snapped in different directions, the frame beams can form a firm frame body limited in upper, lower, left and right directions. Moreover, the platform-type shelf is thus formed, and can be used as a table for placing objects. In addition, a panel can be set on the platform-type shelf so as to be used as a desk, table and so on.
Referring to FIGS. 4 and 5, an assembling method of the above-mentioned components of the present invention is illustrated. Firstly, the downward first engaging grooves of the four lattice beams are aligned with the corresponding upward first engaging grooves thereof (such as 114 is aligned with 145), respectively. Notes that the first engaging grooves and the different-direction first engaging grooves are not snapped together so as to form passages between the intersecting lattice beams (e.g., a horizontal passage is formed between the lattice beams 11 and 13). Secondly, the four lattice beams of the locking lattice beam group B are placed in the passages, and theirs downward first engaging grooves and upward first engaging grooves (such as 214 and 215) are aligned with the upward second engaging grooves and the downward second engaging grooves (such as 146 and 123) of the central lattice beam group A. Thus, the central lattice beam group A and the locking lattice beam group B can be pressed and snapped together at the same time. Alternatively, the engaging grooves 216, 223, 226, 233, 236, 243, 246 and 213 of the lattice beams can be firstly assembled into a big pane, then to assemble the central lattice beams one another and simultaneity to assemble the central lattice beams and the locking lattice beams. Finally, referring to FIG. 6, the mortise grooves (such as 314, 315, 313 and 316) of the frame beams are aligned with the tenons (such as 148, 122, 248 and 222) of the central lattice beam group A and the locking lattice beam group B, and the four frame beams are horizontally pushed and assembled from outside to inside, so that the adjacent outer tenons and inner tenons (such as 312/348 and 319/347) of the frame beam group C are snapped one other.
Referring to FIGS. 7 to 9, a second embodiment of the present invention is shown. The second embodiment is based on the first embodiment and is a platform-type shelf with stilts. Specifically, two ends of the frame beams 31, 32, 33 and 34 have stilts 310/311, 320/321, 330/331 and 340/341 extending therefrom, respectively. The stilts (such as 310 and 311) can be structures directly extending downwards from the snapped outer tenons and the inner tenons (such as 318 and 319). Moreover, the tenons (such as 148, 122, 248 and 222) of the central lattice beam group A and the locking lattice beam group B are centrally positioned with cutouts on theirs upper and lower portions. The mortises (such as 314, 315, 313 and 316) of the frame beams are each in a shape of through hole. When the four frame beams are pushed towards the tenons so that the mortises are inserted by the tenons, the outer tenon 312 of the frame beam 31 presses on the outer tenon 348 of the frame beam 34 with the stilt 341, and the inner tenon 347 of the frame beam 34 presses on the inner tenon 319 of the frame beam 31 (also referring to FIG. 9A, which is an assembling view of the frame beams observed from four visual angles). Therefore, the adjacent stilts 310 and 341 are close combined. In this way, the end stilts of the frame beam 31 and 32, 32 and 33, 33 and 34, 34 and 31 are combined together so as to form a table or a chair with stilts.
Also referring to FIG. 10, which is used for illustrating a changed embodiment of outer tenons and inner tenons of the frame beams (here taking the frame beam 33 as an example). The location of the outer tenon 332 and the inner tenon 339 of the frame beam 33 and instead be an outer tenon 332 a (similar to a tenon) and an inner tenons 339 a (similar to a mortise groove) located at the stilt 330 (the rest may be deduced by analogy) so as to facilitate the application of frame beam in devise or to enhance a connecting stability with multilayered engaging structure of the frame beam.
Referring to FIG. 11, a central lattice beam group A with a central stilt according to an embodiment is shown. The lattice beams 11, 13, 12 and 14 define central stilts 11 c, 13 c, 12 c and 14 c, respectively. The central stilts 11 c, 13 c, 12 c and 14 c can be assembled according to FIGS. 11A to 11C. Also referring to FIGS. 12 and 13, a frame beam group C with a number of stilts according to an embodiment is shown. The stilts (310/311, 330/331, 320/321 and 340/341) at two ends of the frame beams 31, 33, 32 and 34 are assembled into four stilt bodies, and the frame beams 31, 33, 32 and 34 further include central stilts 31 c, 33 c, 32 c and 34 c at the middle portions thereof. The assembled platform-type shelf can decentralize the supporting force thereon, and can enhance its supporting intensity by use of the stilts. Further, the assembled platform-type shelf is convenient to be inserted and lifted by a lift truck. Therefore, this embodiment is very suitable for use as the trestle. Also referring to FIGS. 14 and 15, except that the periphery of the central lattice beam group has different connecting manners, the frame beams used for forming the platform-type shelf further include a number of stilts (such as 320, 32 a, 32 c, 32 b and 321).
In the above-mentioned first and second embodiments, the central lattice beam group A and the locking lattice beam group B are classed for easy to describe. In fact, they can be integrated in one structure. That is, the both lattice beams (11-14, 21-24) can have downward engaging grooves and upward engaging grooves at the same time. Therefore, one main-body structure of the present invention can be formed of two or more lattice beams and the frame beam group C in connection, and another main-body structure of the present invention can be formed of the single frame beam group C in connection (such as shown in FIG. 9A).
Referring to FIGS. 16 and 16A, an embodiment assembled with at least two lattice beams and the frame beam group C is shown. Three lengthways lattice beams 41, 42 and 43 and three transverse lattice beams 51, 52 and 53 are formed into a basic structure via a weaving technique. Then, the basic structure is connected to the frame beam group C. Specifically, the lattice beams have a basic section of a downward engaging groove and a upward engaging groove and a downward engaging groove or a upward engaging groove and a downward engaging groove and a upward engaging groove, respectively. When more lattice beams are used, theirs structures can be foreseen by way of analogy. Anyway, an important structural feature of the lattice beam is that it has both downward engaging groove and upward engaging groove so as to be weaved.
Referring to FIG. 17, a third embodiment of the present invention is shown. The third embodiment is used for illustrating an application of the present platform-type shelf. As shown in this figure, the third embodiment is constituted of an outer-frame box 6, a platform-type shelf 7 and foot parts 8 under the outer-frame box 6. The outer-frame box 6 includes four equal-length outer walls 61, four strengthening walls 62 and four inflexed walls 63. The bottom of the outer-frame box 6 is particularly provided with bottom plates 64 connected with the inflexed walls 63. An inner pad plate 68 and the platform-type shelf 7 are close inserted into the outer-frame box 6, so as to form a firm box with excellent carrying capacity (compressive resistance). The foot parts 8 can be positioned under the outer-frame box 6 so that a lift truck can lift the box by inserting into the foot parts 8.
Also referring to FIG. 18, the outer-frame box 6 can be formed by folding a paperboard such as corrugated paper. The folding process includes steps of: folding the outer walls 61 and making them upright, folding the strengthening walls 62 and making them aclinic, folding the inflexed walls 63 towards the bottom of the box, forming the bottom plates 64 and 65 and making them joint with the bottom of the box so as to be pressed by the inner pad plate 68 and the platform-type shelf 7. Each of two opposite inflexed walls 63 has two insertion parts 66 and 67 directly extending therefrom so as to insert between the adjacent outer wall 61 and the inflexed walls 63 and to form a very firm box with restricting effect. Each of the foot parts 8 includes three agglutinate bodies. Each agglutinate body is formed by agglutinating four cubic poles (such as cubic poles 81 and 82 made of corrugated paper). A group of three agglutinate bodies are arranged and agglutinated on a strip-type covering plate 83. Further, the two agglutinate bodies at two ends of the covering plate 83 are covered by the covering plate 83 at four sequential sides, and the middle agglutinate body is additionally covered by a covering plate 84 at three sequential sides, so that the firm degree of the foot part is enhanced. Referring to FIGS. 19A and 19, lengthways lattice beams 71 and frame beams 72 of the platform-type shelf 7 can be formed by multilayered corrugated paperboard (or other material), theirs structures are the same as these mentioned above.
Referring to FIGS. 20 and 21, the assembled outer-frame box 6, inner pad plate 68, supporting body 7 and a top plate 73 can be used for supporting a protecting wall 9 of a large packing box. In use, the top plate 73 is lower than the strengthening walls 62 and is a bottom for directly supporting the protecting wall 9, and a coping box 95 is used for covering the top of the protecting wall 9. The coping box 95 can be similarly to the outer-frame box 6. If necessary, the inner pad plate, the supporting body, and/or the top plate can also be set in the coping box 95. The protecting wall 9 is constituted of an outer layer 93 and an inner layer 94. If necessary, a number of strengthening blocks 92 and angled strengthening blocks 91 can be set between the outer layer 93 and the inner layer 94.
Referring to FIGS. 22A and 22, the height of the supporting body 7 and the top plate 73 is equal to that of the outer-frame box 6. Thus, a general pallet is formed. Referring to FIG. 23, multilayered corrugated paperboards 68 with different corrugated directions are used in the outer-frame box 6 instead of the supporting body 7 so as to support weight objects. Referring to FIGS. 24 and 24A, the outer-frame box 6 is higher than the supporting body 7 and the top plate 73 assembled therein so as to carry many objects with small bulk.
Referring to FIG. 25, a strengthened supporting body 7 is shown. Specifically, each pane space 74 of the large supporting body 7 (or some given pane spaces) is inserted into a small supporting body 7A with suitable size so as to have a considerable supporting force. Referring to FIG. 26, each pane space of the large supporting body 7 (or some given pane spaces) is diagonally inserted into an inner supporting plate 75 made of multilayerred corrugated papers agglutinated together, so as to strengthen the supporting panes 74 of the supporting body 7.
The above description is given by way of example, and not limitation.
