Title: Safety paper table

Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention relates to a safety paper table, and more particularly, to a table wherein the ends of the table top and the table feet are foldable, thereby forming arched surfaces to prevent users from cut injuries.  
       [0003] 2. Description of the Prior Art  
       [0004] A conventional environmental paper table disclosed in TW 422021 and shown in FIGS. 1 through 3, includes two pairs of longitudinal and lateral plates  50 ,  51  both of which are engaged to each other by crossing themselves. As a result, the table base is created for table top  53 . Thereafter, a pair of strengthening ribs  52  which also cross themselves are engaged to the table base. Finally, The table top  53  with attachment flaps  531  disposed therearound is fixed on the table base by means that the attachment flaps  531  folded inwardly are mounted on the table base. Accordingly, a resuable paper table is created. Since the longitudinal and lateral plates  50 ,  51  belong single-plate construction, the sharp corner thereof will injure users. It&#39;s often to hear that users are cut by paper. Moreover, the structural strength of this conventional paper table is insufficient because the table base is produced only by crossing the single-plate type longitudinal and lateral plates  50 ,  51  which are engaged with each other.  
       SUMMARY OF THE INVENTION  
       [0005] It is a primary object of the present invention to provide a safety paper table which won&#39;t cause cut injuries.  
       [0006] It is another object of the present invention to provide a safety paper table whose structure can be strengthened.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0020] First of all, referring to FIG. 4, the first table foot  10  in accordance with the present invention includes a main plate  11  to both sides of which attachment flaps  12 L,  12 R with half the width of the main plate  11  are connected. Long and short locking slots  13 ,  14  with openings directed downwardly are symmetrically disposed at both sides of the main plate  11 . The long locking slot  13  is arranged adjacent to the outer edge of the main plate  11  while the short locking slot  14  is disposed at the center between the long locking slot  13  and the middle line of the main plate  11 . In addition, indentations  15  are formed at the bottom of the main plate  11  adjacent to the long locking slots  13  such that locking heads  16  are created at the outer side of the indentations  15 . Moreover, a pair of locking members  17  are disposed at the center of the top of the main plate  11 . Each locking member  17  has a mounting slot  18  with an opening directed downwardly. Meanwhile, the locking member  17  is connected with the main plate  11  through side interconnection members  19 .  
     [0021] Correspondingly to the main plate  11  in such a way of mirror activities, both attachment flaps  12 L,  12 R include long locking slots  13 , short locking slots  14 , indentations  15 , locking heads  16 , locking members  17 , mounting slots  18  and side interconnection members  19 . After the attachment flaps  12 L,  12 R are folded inwardly, a double-layer structure is created, thereby forming arched surface of the end edges.  
     [0022] In addition, the present invention includes a second table foot  20 , as shown in FIG. 5, to both sides of which attachment flaps  22 L,  22 R with half the width of the main plate  21  are connected. Besides, the attachment flaps  22 L,  22 R have locking and mounting structure corresponding to the main plate  21  in such a way of mirror activities. Corresponding to the table foot  10 , the main plate  21  also has long locking slots  23  with opening directed upwardly, short locking slots  24  with opening directed downwardly, indentations  25  formed at the bottom corners of the main plate  21  in such a way that locking heads  26  are created by means of the indentations  15 . Furthermore, corresponding to the table foot  10 , the main plate  21  also has a pair of locking members  27  at the top center thereof. Meanwhile, the locking members  27  include mounting slots  28  with opening directed upwardly. Moreover, the locking members  27  are connected to the main plate  21  through side interconnection members  29 . After the attachment flaps  22 L,  22 R are folded inwardly, a double-layer structure is also created, thereby forming arched surface of the end edges.  
     [0023] A table top  30 , as shown in FIG. 6, includes a panel  31  having first folding members  32 , mounting members  33 , second folding members  34  and sticking members  35  disposed one after another therearound. Each mounting member  33  has a pair of outer locking holes  36  and a pair of inner locking holes  37 . The outer locking holes  36  correspond to the locking heads  16 ,  26  of the first and second table feet  10 ,  20 . Thereafter, members  32 ,  33 ,  34  disposed around the panel  31  are folded and fixed in place on the internal side of said panel  31  by means of the sticking members  35  (see FIG. 10), thereby forming a table top with side frame.  
     [0024] In order to strengthen the structure of the panel  30 , as shown in FIG. 7, two pairs of strengthening ribs  40 U,  40 D forming a nine square grid are engaged into the inner locking holes  37  of the panel  30 . Besides, the strengthening ribs  40 U,  40 D are provided with top and bottom locking slots  41 ,  42 . Also, the strengthening ribs  40 U,  40 D have indentations  43  and slots  44  formed at the bottom of both ends thereof so as to create locking members  45  corresponding to the inner locking holes  37  of the panel  30 . Moreover, the first and second table feet  10 ,  20  are engaged each other into a table base by means that the corresponding long locking slots  13 ,  23  of the first and second table feet  10 ,  20  and the corresponding mounting slots  18 ,  28  of the locking members  17 ,  27  are inserted each other. Meanwhile, both pairs of strengthening ribs  40 U,  40 D are fixed to the first and second table feet  10 ,  20  by means of the short locking slots  14 ,  24 . In addition, the first and second table feet  10 ,  20  are connected to the table top  30  by means that the locking heads  16 ,  26  are inserted into the outer locking holes  36  of the table top  30  (see FIGS. 8 and 9).  
     [0025] Based on the above-mentioned configuration, as shown in FIGS. 11 and 12, the table base is created by locking the first and second table feet  10 ,  20  to each other. The first and second table feet  10 ,  20  are connected with attachment flaps  12 L,  12 R,  22 L,  22 R to both sides thereof. Besides, the attachment flaps  12 L,  12 R,  22 L,  22 R have the same structure as the main plates  11 ,  21  in a manner of mirror activities. Accordingly, a double-layer construction is created after the attachment flaps  12 L,  12 R,  22 L,  22 R are folded onto the main plates  11 ,  21 , thereby forming an arched surface R at the end edges (see FIG. 12) to prevent users from cut injuries. Also, the double-layer construction is able to enhance the structural strength. Additionally, the attachment members of the first and second table feet  10 ,  20  are much increased to enhance the fixing effect. Furthermore, the ground-contacting surfaces are expanded to enhance the structural strength as well.  
     [0026] Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
