Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a lampshade assembly and, more particularly, to a lampshade assembly having a plurality of lampshade pieces that can be stacked up on one another.

2. Description of the Related Art

The design of the lampshade assembly accompanied with the light brightness of the lamp contributes to the creation of a specific atmosphere in its environment. The lampshade assembly may be designed according to various styles following the current fashion.

Once it is achieved, the lampshade assembly is delivered to the vendor. In order to optimize the yield, it is desirable that one delivery can provide a higher amount of products. The transport cost can be thereby compensated with a greater amount of products carried per delivery.

Referring to FIG. 1 , a lampshade assembly of the prior art comprises a lampshade 10 and a frame 11 . One portion of the frame 11 is connected to the top of the lampshade 10 while another portion is connected to a rod 12 of the lamp 1 . The rod 12 is further connected to a socle 13 of the lamp structure 1 . When the above conventional lamp to be packed, the packing box needed usually has to have a width L that has at least the dimension of the lampshade 10 .

The above lampshade structure of the prior art is formed in a single body, and has a lower potion that is dimensionally larger than the socle of the lamp. The size of the packaging box therefore has to be dimensionally adapted to the size of the lampshade. From a packaging consideration, the empty space within the lampshade represents waste of space that is usually filled with a gap-filling material to prevent the damage of the lampshade due to external shocks. As a result, the transportation of the packaged lampshade requires a substantial space, which undesirably increases the packaging cost and the transport cost.

SUMMARY OF THE INVENTION

It is therefore a principal object of the invention to provide a lampshade assembly that the packing space of the lampshade assembly is greatly reduced, and less packing material is needed. The packing cost and the transport cost are thereby reduced, and it is more convenient to carry the lampshade packing box.

A securing piece 27 , having bent portions 28 respectively at two ends, is pivotally connected to the bent portion 26 .

The connection mechanism 3 includes an upper cap 4 , a first fitting piece 5 , a fitting set 6 , and a spring 9 .

The upper cap 4 is, for example, a disk with a central hole 40 . At least one rib 41 having a notch 42 is formed at a periphery of the upper cap 4 . The number of ribs 41 is equal to the number of lampshade pieces 20 .

The first fitting piece 5 is, for example, a ring. The first fitting piece 5 has an inwardly extended circular flange 50 on its top. One end of a connecting rod 51 is attached to a side surface of the first fitting piece 5 , and the other end is attached to the upper bar 21 . Two notches 52 , 53 are formed on a top of the first fitting piece 5 in a manner that the notches 52 , 53 and the connecting rod 51 are equally spaced apart from one another. A bump 54 is further formed on an outer surface of the first fitting piece 5 to snap fit the rib 41 of the upper cap 4 .

The fitting set 6 is arranged between the upper cap 4 and the first fitting piece 5 . The fitting set 6 includes a second fitting piece 7 and a third fitting piece 8 . The second fitting piece 7 is, for example, a ring having an inwardly extended flange 70 and an outwardly extended flange 71 respectively at a top and bottom thereof. One end of a connecting rod 72 is attached to a side surface of the second fitting piece 7 , and the other end is attached to an upper bar 21 of another lampshade 20 . The connecting rod 72 is longer than the connecting rod 51 of the first fitting piece 5 . A notch 73 is formed on a top of the second fitting piece 7 in a manner that the notch 73 and the connecting rod 72 respectively correspond to the notches 52 , 53 . The third fitting piece 8 is, for example, a ring having an inwardly extended flange 80 and an outwardly extended flange 81 respectively at a top and bottom. One end of a connecting rod 82 is further attached to a side surface of the third fitting piece 8 , and the other end is attached to an upper bar 21 of another lampshade piece 20 . The connecting rod 82 is longer than the connecting rod 72 .

The spring 9 inserts respectively inside the upper cap 4 , the first fitting piece 5 and the fitting set 6 . An urging portion 90 is provided on a top of the spring 9 . The urging portion 90 is, for example, a ring having an outwardly extended flange 91 . A lower cap 92 having a circular flange 93 around a central portion thereof is connected to a bottom of the spring 9 .

In FIG. 5 , the second fitting piece 7 fits inside the first fitting piece 5 in a manner that an upper portion of the second fitting piece 7 protrudes through the inwardly extended circular flange 50 of the first fitting piece 5 . A top of the third fitting piece 8 fits through the inwardly extended flange 70 of the second fitting piece 7 .

The lower cap 92 snap fits with the bottom of the first fitting piece 5 .

When no external force is applied to the spring 9 , the upper cap 4 and the first fitting piece 5 are separated from each other. The outwardly extended flange 71 of the second fitting piece 7 abuts against the inwardly extended circular flange 50 of the first fitting piece 5 . The outwardly extended flange 81 of the third fitting piece 8 abuts against the inwardly extended flange 70 of the second fitting piece 7 . The outwardly extended flange 91 of the urging portion 90 abuts against the inwardly extended flange 80 of the third fitting piece 8 . As shown in FIG. 3 , the upper cap 4 , the first fitting piece 5 and the fitting set 6 are disassembled by outwardly stretching the spring 90 . Then, the lampshade pieces 20 can be stacked up on one another.

Referring to FIG. 8 and FIG. 1 , when the lamp structure 1 having the lampshade assembly is packed, the volume occupied by the lampshade 2 is greatly reduced. Less packing material is therefore needed. Furthermore, the width L 1 of a packing box for the lampshade assembly according to the invention is significantly reduced. It is therefore more convenient to carry such a lampshade packing box. More boxes can be placed in the same transportation container for transport, and the transport cost per lamp is reduced.

In FIG. 2 , FIG. 4 and FIG. 6 , when the lampshade 20 is to be assembled, the connecting rod 72 and the notch 73 of the second fitting piece 7 respectively fit into the notches 52 , 53 . The connecting rod 82 of the third fitting piece 8 corresponds to the notch 73 of the second fitting piece 7 . The connecting rods 51 , 72 , 82 uniformly radiate around a circle. The upper cap 4 presses upon the first fitting piece 5 to allow the second and third fitting pieces 7 , 8 to lie proximate to the lower cap 92 . The second fitting piece 7 and the first fitting piece 5 then are adjacently under the bottom of the upper cap 4 . The connecting rod 72 of the second fitting piece 7 is partially located inside the notch 52 of the first fitting piece 5 . The connecting rod 82 of the third fitting piece 8 is partially located respectively inside the notch 73 of the second fitting piece 7 and the notch 53 of the first fitting piece 5 . Then, the upper cap 4 is rotated to fit the notch 42 of the rib 41 to the bump 54 of the first fitting piece 5 to prevent the spring 9 from resiliently leaving the connection mechanism 3 . Referring to FIG. 7 , the lampshade pieces 20 are attached side by side in a manner that the hooks 25 of the connecting element 24 respectively hook the upper bars 21 of the adjacent lampshade pieces 20 , and the bent portion 28 of the securing piece 27 respectively hook the side bars 22 .

The lampshade is divided into a plurality of lampshade pieces and assembled by means of the connection mechanism as described above, regardless of the size of the lampshade. The fitting set includes ring-shaped fitting pieces with different sizes so that the fitting pieces can pivotally fit with one another. The smaller fitting piece (the third fitting piece) has the connecting rod longer than the larger one (the second fitting piece). The larger fitting piece is provided with a notch on its top for receiving the connecting rod of the smaller fitting piece so that the connecting rods of the smaller and larger fitting pieces are equally spaced apart from one another. The larger fitting piece fits into the first fitting piece, with the notch of the first fitting piece corresponding to the connecting rod of the first fitting piece. Then, the upper cap is connected to the first fitting piece. By this way, the lampshade can be assembled and disassembled into the lampshade pieces.

As described above, the lampshade assembly according to the invention therefore includes at least the following advantages. By means of the connection mechanism, the lampshade pieces can be stacked into a smaller configuration. Therefore, not only the transport cost is reduced, but also the filling material used to absorb shock is reduced.
