Abstract
A collapsible lampshade frame has an upper ring (10), a lower ring (20) and multiple ribs (30). The upper ring (10) has a central mounting bracket (11), multiple radial supports (12) and an outer ring (13). Each radial support (12) has a bottom and multiple wavy recesses (121). The wavy recesses (121) are formed on the bottom of the radial supports (12). Each rib (30) has a distal end and a fork (32). The fork (32) is formed in the distal end and engages the wavy recesses (121) on the radial supports (12). When the forks (32) are disengaged from the wavy recesses (121), the ribs (30) can be pivoted so the frame occupies a small volume.
Description

2 BAC_K_GROL~ND OF THF,l~~NTTON
3 1. Field of the Invention 4 The present invention relates to a lampshade frame, especially to a collapsible lampshade frame.
6 2. Description of the Prior Arts 7 Most lamps such as table lamps or floor lamps usually comprise a stand 8 or body, a bulb and a lampshade. The lampshade is mounted on the stand or body 9 and is mounted around the bulb to keep the bulb from being inadvertently touched and to soften or direct the light from the bulb. The conventional 11 lampshade comprises a shade and a frame. The frame is maunted on the stand or 12 body. The shade is mounted on the frame. When the lamp is moved or stored, the 13 bulb, the stand or body and the lampshade can be moved separately. However, 14 the frame is a single unit and cannot be taken apart and reassembled easily.
Therefore when the lamp is moved or stored, the frame will occupy too much 16 space.
I7 To overcome the shortcoming, the present invention provides a 18 collapsible lampshade frame to mitigate or obviate the aforementioned 19 problems.
2I The main objective of the present invention is to provide a collapsible 22 lampshade frame. A collapsible lampshade frame in accordance with the present 23 invention comprises an upper ring; a lower ring and multiple ribs. The upper ring 24 has a central mounting bracket, multiple radial supports and an outer ring.
Each i radial support has a bottom and multiple wavy recesses. The wavy recesses are 2 formed on the bottom of the radial supports. Each rib has a distal end and a fork.
3 The fork is formed in the distal end and engages the wavy recesses on the radial 4 supports. When the forks are disengaged from the wavy recesses, the ribs can be pivoted on the lower ring so the frame occupies a small volume.
6 Other objectives, advantages and novel features of the invention will 7 become more apparent from the following detailed description when taken in 8 conjunction with the accompanying drawings.

18 DETAILED DE~CRrPTION OF TH P_R_ 1~.~RM~oI~IMENT~
19 With reference to Fig. 1, a collapsible lampshade frame in accordance with the present invention comprises an upper ring ( 10), a lower ring (20) and 21 multiple ribs (30).
22 With further reference to Figs. 2 and 3, the upper ring (10) has a central 23 mounting bracket ( 11 ), multiple radial supports ( 12} and an outer ring (13). The 24 multiple radial supports (12) connect to and extend out radially from the central 1 mounting bracket ( 11 ), and each radial support ( 12) has a top, a bottom and 2 multiple wavy recesses ( 121 ). The wavy recesses ( I21 ) are formed on the bottom 3 of the radial support ( 12). The outer ring { I3} is connected to the multiple radial 4 supports {12). The wavy recesses (121) are formed optionally near the outer ring (13).
6 The lower ring (20) has a split (21).
7 The ribs (30) are attached to the lower ring (20), and each rib {30) has a 8 proximal end, a distal end; a through hole (31 ) and a fork (32). The through hole 9 (31 ) is formed in the proximal end of the rib {30), and the lower ring (20) passes through the through hole (31) at the split {21) in the lower ring (20) to mount the 11 ribs {30) pivotally on lower ring (20). The fork (32) is formed in the distal end of 12 the rib (30) and engages the wavy recesses (121) on the radial support (12).
13 Using three ribs {30) is a preferred option because requires the smallest amount 14 of material to get a stable condition. Nevertheless, using more than three ribs is still practical.
16 With further reference to Fig. 4, the frame is collapsed by disengaging 17 the forks (32) in the ribs (30) from the wavy recesses (121) on the radial supports 18 (I2) of the upper ring (10). Then the ribs (30) are pivoted inward on the lower i 9 ring (20) to reduce the volume of the frame. Therefore when the frame for the lamp is moved or stored, the frame can be collapsed and will not occupy 21 excessive space.
22 Even though numerous characteristics and advantages of the present 23 invention have been set forth in the foregoing description, together with details 24 of the structure and features of the invention, the disclosure is illustrative only.
Changes may be made in the details, especially in matters of shape, size, and 2 arrangement of parts within the principles of the invention to the full extent 3 indicated by the broad general meaning of the terms in which the appended 4 claims are expressed.

18 DETAILED DE~CRrPTION OF TH P_R_ 1~.~RM~oI~IMENT~
19 With reference to Fig. 1, a collapsible lampshade frame in accordance with the present invention comprises an upper ring ( 10), a lower ring (20) and 21 multiple ribs (30).
22 With further reference to Figs. 2 and 3, the upper ring (10) has a central 23 mounting bracket ( 11 ), multiple radial supports ( 12} and an outer ring (13). The 24 multiple radial supports (12) connect to and extend out radially from the central 1 mounting bracket ( 11 ), and each radial support ( 12) has a top, a bottom and 2 multiple wavy recesses ( 121 ). The wavy recesses ( I21 ) are formed on the bottom 3 of the radial support ( 12). The outer ring { I3} is connected to the multiple radial 4 supports {12). The wavy recesses (121) are formed optionally near the outer ring (13).
6 The lower ring (20) has a split (21).
7 The ribs (30) are attached to the lower ring (20), and each rib {30) has a 8 proximal end, a distal end; a through hole (31 ) and a fork (32). The through hole 9 (31 ) is formed in the proximal end of the rib {30), and the lower ring (20) passes through the through hole (31) at the split {21) in the lower ring (20) to mount the 11 ribs {30) pivotally on lower ring (20). The fork (32) is formed in the distal end of 12 the rib (30) and engages the wavy recesses (121) on the radial support (12).
13 Using three ribs {30) is a preferred option because requires the smallest amount 14 of material to get a stable condition. Nevertheless, using more than three ribs is still practical.
16 With further reference to Fig. 4, the frame is collapsed by disengaging 17 the forks (32) in the ribs (30) from the wavy recesses (121) on the radial supports 18 (I2) of the upper ring (10). Then the ribs (30) are pivoted inward on the lower i 9 ring (20) to reduce the volume of the frame. Therefore when the frame for the lamp is moved or stored, the frame can be collapsed and will not occupy 21 excessive space.
22 Even though numerous characteristics and advantages of the present 23 invention have been set forth in the foregoing description, together with details 24 of the structure and features of the invention, the disclosure is illustrative only.
Changes may be made in the details, especially in matters of shape, size, and 2 arrangement of parts within the principles of the invention to the full extent 3 indicated by the broad general meaning of the terms in which the appended 4 claims are expressed.
