(14) With reference to FIGS. 3 to 6, the assembly device is connected to the mounting frame 41 and the table board 42 of the table 40 and has an assembling mount 10 and at least one engaging element 20.

(15) The assembling mount 10 has a connecting portion 11 and an engaging portion 12. The connecting portion 11 is disposed at a lower part of the assembling mount 10 and has a leg hole 13 and at least one connecting panel 14. The leg hole 13 is formed in a bottom of the connecting portion 11 and is connected to one of the supporting legs 43 of the mounting frame 41. The at least one connecting panel 14 is disposed at a side of the leg hole 13 and is pivotally connected to one of the connecting shafts 44 of the mounting frame 41. Furthermore, the connecting portion 11 has multiple connecting panels 14 arranged around an outer periphery of the leg hole 13. Preferably, with reference to FIGS. 4 and 6, the connecting portion 11 has four said connecting panels extended in four different directions, respectively. With reference to FIGS. 1 and 2, the four said connecting panels 14 are pivotally connected to the multiple connecting shafts 44 of the mounting frame 41. Furthermore, each connecting panel 14 is pivotally connected to the corresponding connecting shaft 44 by riveting with a rivet 47. In addition, the pivotal connection is not limited to the type of rivet 47, as long as each connecting shaft 44 can be pivotally connected to the corresponding connecting panel 14.

(16) With reference to FIGS. 3 to 6, the engaging portion 12 is disposed at an upper part of the assembling mount 10, is connected to the connecting portion 11, and has at least one engaging hole 15. The at least one engaging hole 15 is formed through a top side and a bottom side of the engaging portion 12 and aligns with one of the assembling holes 46 of the table board 42. Furthermore, with reference to FIGS. 4 and 6, the engaging portion 12 has at least one limiting protrusion 16 formed on and protruded from the bottom side of the engaging portion 12 and disposed at an outer periphery of the at least one engaging hole 15. Preferably, the engaging portion 12 has two said limiting protrusions 16 formed on the bottom side of the engaging portion 12 at the outer periphery of the at least one engaging hole 15. Additionally, the two said limiting protrusions 16 are disposed at a spaced interval and are respectively disposed at two sides of the at least one engaging hole 15. Furthermore, each one of the at least one engaging hole 15 has an extension direction of length being the same as an extension direction of length of the at least one connecting panel 14. Preferably, the engaging portion 12 is provided with the engaging holes 15 in the same number as the connecting panels 14, and each one of the engaging holes 15 is located between two adjacent connecting panels 14.

(17) With reference to FIGS. 5, 6, and 7, the at least one engaging element 20 is detachably connected to the assembling mount 10, is inserted in the at least one engaging hole 15 of the assembling mount 10 via one of the assembling holes 46 of the table board 42, and abuts against the bottom side of the engaging portion 12 to hold the table board 42 between the at least one engaging element and the assembling mount 10 and to dispose the table board 42 above the mounting frame 41 via the assembly device of the present invention. Each one of the at least one engaging element 20 has an elastic engaging segment 21 and a head segment 22. The elastic engaging segment 21 is disposed at a bottom end of the at least one engaging element 20 and selectively abuts against the bottom side of the engaging portion 12 of the assembling mount 10 to hold the at least one engaging element 20 with the assembling mount 10.

(18) Furthermore, the elastic engaging segment 21 has two engaging ribs 23 disposed at a spaced interval, and the two engaging ribs 23 can be deformed by an external force to move close to each other, so that the elastic engaging segment 21 deformably extends into the at least one engaging hole 15, and abuts against the bottom side of the engaging portion 12 after extending out of the at least one engaging hole 15. Additionally, each one of the two engaging ribs 23 has an abutting protrusion 24 disposed on an outer side of the engaging rib 23. When each one of the engaging ribs 23 extends out of the bottom side of the engaging portion 12, the abutting protrusion 24 of each engaging rib 23 abuts against the bottom side of the engaging portion 12. Preferably, the abutting protrusion 24 of one of the two engaging ribs 23 abuts against the two limiting protrusions 16 of the engaging portion 12 to enable the elastic engaging segment 21 of the at least one engaging element 20 stably abutting the engaging portion 12 of the assembling mount 10.

(19) With reference to FIGS. 5, 6, and 7, the elastic engaging segment 21 has a guide block 25 obliquely disposed below each one of the two abutting protrusions 24. With reference to FIG. 8, when each one of the two engaging ribs 23 extends through the at least one engaging hole 15, the guide block 25 at each engaging rib 23 abuts an inner side of the at least one engaging hole 15 to enable the two engaging ribs 23 to deform and to move toward each other. With reference to FIG. 7, when the two engaging ribs 23 extend out of the bottom side of the engaging portion 12, the two engaging ribs 23 are moved away from each other to the original position, and this enables one of the two abutting protrusions 24 to abut against the two limiting protrusions 16 of the engaging portion 12.

(20) In addition, the elastic engaging segment 21 has an inclined face 26 formed on each one of the two engaging ribs 23 above the abutting protrusion 24 to increase an elastic deformation range of the corresponding engaging rib 23. The head segment 22 is disposed on an end of the elastic engaging segment 21 away from the two engaging ribs 23 and is connected to the elastic engaging segment 21. When the elastic engaging segment 21 abuts against the engaging portion 12, the head segment 22 is mounted in the corresponding assembling hole 46 of the table board 42 and abuts against the stepped face 461. Preferably, the assembly device of the present invention is provided with the engaging elements 20 in the same number as the engaging holes 15, so that each one of the engaging elements 20 engages with one of the engaging holes 15 of the assembly device 10. Then multiple table boards 42 can be connected with each other by the multiple engaging elements 20 and the multiple engaging holes 15 to provide a splicing effect of multiple table boards 42.

(21) With reference to FIGS. 5 and 6, when assembling the table 40, the assembling mount 10 of the assembly device of the present invention is moved below the table board 42 to align the at least one engaging hole 15 with one of the assembling holes 46 of the table board 42. Then the at least one engaging element 20 is inserted into the corresponding assembling hole 46 from the top side of the table board 42. At this time, with reference to FIG. 8, the two guide blocks 25 of the elastic engaging segment 21 abut the inner side of the at least one engaging hole 15 to enable the two engaging ribs 23 to deform and to move toward each other. With reference to FIG. 7, when the bottom end of the at least one engaging element 20 extends out of the bottom side of the engaging portion 12, the two engaging ribs 23 pressed by the inner side of the at least one engaging hole 15 are deformed to move back to the original position, the abutting protrusion 24 of one of the two engaging ribs 23 abuts against the two limiting protrusions 26, and the abutting protrusion of the other one of the two engaging ribs 23 abuts against the bottom side of the engaging portion 12. At the same time, the head segment 22 of the at least one engaging element 20 abuts against the stepped face 461 of the corresponding assembling hole 46. Then the table board 42 can be stably disposed between the assembling mount 10 and the at least one engaging element 20, and can be disposed on the mounting frame 41 via the assembly device of the present invention easily and conveniently.

(22) With reference to FIGS. 9 and 10, when the table 40 needs to be stored or carried after use, the user only needs to press the two engaging ribs 23 of the at least engaging element 20 to move toward each other and to separate from the two limiting protrusions 16 and the bottom side of the engaging portion 12, and pushes the at least one engaging element 20 to move upwardly relative to the assembling mount 10. Then the at least one engaging element 20 can be separated from the assembling mount 10 and the table board 42 conveniently and quickly. With reference to FIGS. 11 and 12, when the user wants to assemble multiple table boards 42, since the engaging portion 12 of the assembling mount has multiple said engaging holes 15, two of the multiple said engaging holes respectively align with two assembling holes 46 of two adjacent table boards 42, and two said engaging elements 20 are respectively inserted into the two engaging holes 15 of the assembling mount 10 via the two corresponding assembling holes 46 of the two adjacent table boards 42. Then the user can flexibly and conveniently assemble different numbers of table boards 42 according to needs to expand the usable area.

(23) According to the above-mentioned structural relationships and features of the assembly device for a table of the present invention, the assembling mount can be assembled with multiple table boards 42 by the engaging holes 15 and the engaging elements 20, and this is different from the assembly device of the conventional table, since the assembling mount of the conventional table only has a single eccentric portion and can only be assembled with a single table board. Therefore, the assembly device for a table of the present invention can improve the practicality and flexibility in use without forming the eccentric portion on the external surface of the assembling mount 10, and this can also reduce the volume and weight of the assembling mount 10 and allow the user to conveniently store and carry the assembly device of the present invention.

(24) Furthermore, the assembly device of the present invention does not need to embed the engaging panel in the table 42, and this can reduce the cost of using the assembly device, can reduce the overall weight of the table 42, and can reduce the burden of storing and carrying the table 40. In addition, in the present invention, the at least one engaging element 20 can be elastically deformed to abut against the assembling mount 10 to assemble the table board 42 with the mounting frame 41, the two abutting protrusions 24 abut against the two limiting protrusions 16 and the bottom side of the engaging portion 12, and the head segment 12 of the at least one engaging element 20 abuts against the stepped face 461 of the corresponding assembling hole 46. Then the table board 42 can be held securely and stably between the assembling mount 10 and the at least one engaging element 20 to dispose on the mounting frame 41, and the disassembly of the at least one engaging element 20 will not be affected by the relative displacement or deflection between the table board 42 and the mounting frame 41, so the assembly or disassembly of the assembly device for a table 40 of the present invention can be carried out conveniently and quickly.

(25) Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the utility model, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended 10 claims are expressed.
