A pivotal rod 4, which has a radial through hole 41, is turnably passed into the co-axial tube portions 24 with the radial hole 41 being located between the co-axial tube portions 24. Furthermore, the lo locating seat member 2 is equipped with a fastening member 3, which includes a lever 31, a rod-shaped part 32, a pressing block 33, a spring 34, and a nut 35. The lever 31 is formed with a pushing portion 311, and a loosening portion 312 at a front end, and is pivotally connected to an upper end of the rod-shaped portion 32 at the front end. The rod-shaped part 32 is formed with screw threads on a lower end, and is passed through the pressing block 33, the spring 34, the radial through hole 41 of the pivotal rod 4 in sequence from the lower end, and connected to the nut 35 at the threaded lower end thereof. Thus, the fastening member 3 is fitted to the pivotal rod 4, which can turn on the locating seat member 2, while the pressing block 32 is biased towards the front end of the lever 31 by the spring 34. And, when the lever 31 is moved to such a position that the pushing portion 311 thereof contacts the pressing block 33, the pressing block 33 will be moved to a lowermost position. When the s lever 31 is moved to such a position that the loosening portion 312 thereof contacts the pressing block 33, the pressing block 33 will be biased upwards and away from the lowermost position by the spring 34.
The connecting seat member 5 has a top portion, two lateral wall portions 51, 52 projecting down from lateral edges of the top portion, and a receiving gap 53 on a front end of the top portion, which wall portions 51, 52 have co-axial through holes (not numbered) thereon.
Furthermore, the connecting seat member 5 has an engaging pin 6 passed through the through holes of the wall portions 51 and 52. The engaging lo pin 6 is formed with a pressed end portion 61 at a first end, a thin portion 66 next to the pressed end portion 61, a cone-shaped portion 67 next to the thin portion 66, a stopped portion 64 next to the cone-shaped portion 67, and an insertion portion 62 at the other end, which is thinner than the stopped portion 64; the stopped portion 64 is wider than the gap 22 of IS the locating seat member 2, but it is slightly narrower than the through hole 21 of the locating seat member 2 while the thin portion 66 is narrower than the gap 22; the pressed end portion 61 is passed through the wall portion 51 while the insertion portion 62 is passed through a spring 63, and the wall portion 52 in sequence such that the spring 63 will bias the pin 6 in a direction away from the wall portion 52. In addition, a detaining element 65 is secured around an inner end of the pressed end portion 61 for preventing the engaging pin 6 from falling out of the connecting seat member 5; the detaining element 65 can be a ring- shaped one.
In addition, the front part 11 has two extension portions 13 at lateral portions thereof, each of which is formed with a gap 131 at a rear end, while the rear part 12 is formed with two projections 14 on lateral sides thereof; to join the rear part 12 to the front part 11, the projections 14 are first fitted into respective ones of the gaps 131 of the extension portions 13 for the rear part 12 to be positioned in proper position as well as for allowing the rear part 12 to pivot on the rear ends of the extension portions 13.
lo To connect the rear part 12 to the front part 11, referring to Figs. 1 to 4, the rod-shaped part 32 of the fastening member 3 is laid down with the loosening portion 312 of the lever 31 facing it, and the rear part 12 is lifted at the front end, and the projections 14 are fitted into respective ones of the gaps 131 of the extension portions 13. Next, the rear part 12 IS is pivoted on the rear ends of the extension portions 13 such that the connecting seat member S is fitted over the locating seat member 2, and such that the engaging pin 6 is pressed against the slope 23 at the cone-shaped portion 67 thereof; during downward movement of the engaging pin 6 together with the seat member 5, the pin 6 will be made to move in such direction as to compress the spring 63 owing to contact of the cone-shaped portion 67 with the slope 23, and in turns, the engaging pin 6 is passed through the gap 22 of the locating seat member 2, and into the through hole 21 from the thin portion 66 thereof. Finally, the engaging pin 6 is moved by the spring 63 such that the stopped portion 64 is through me through hole 21; thus, the engaging pin 6 engages the locating seat member 2, and the connecting seat member 5 is stopped from separating from the locating seat member 2. Then, the s fastening member 3 is upwards pivoted, and fitted into the receiving gap 53 of the connecting seat member 5 at the rod-shaped portion 32, and the lever 31 is pivoted to such a position as to press the pressing block 33 against the connecting seat member 5 at the pushing portion 311 thereof; thus, the seat members 2 and 5 are securely connected.
Referring to Figs. 3, 5 and 6, to separate the rear part 12 from the front part 11, first the lever 31 is pivoted to such a position as to face the pressing block 33 at the loosening portion 312 thereof, and the rod-shaped portion 32 is moved away from the receiving gap 53 of the connecting seat member 5. Next, the end portion 61 of the engaging pin 6 is pressed such that the stopped portion 64 is away from the through hole 21, and the thin portion 66 is in the through hole 21. Then, the rear part 12 is pivoted on the rear end of the extension portions 13 for the front end thereof to be lifted. Thus, both the engaging pin 6 and the connecting seat member 5 are moved away from the locating seat member 2, and the rear part 12 separated from the front part 11.
Referring to Fig. 7, in a second embodiment, two engaging pins 6 are fitted to the connecting seat member 5 instead while the locating seat member 2 is formed with two fitting portions for connection with respective ones of the engaging pins 6, each of which fitting portions has a through hole 21, a gap 22, and a slope 23 like the fitting portion of the first embodiment. The engaging pins 6, 6 are passed through respective ones of the wall portions 51, 52 of the connecting seat s member 5 at pressed end portions 61 thereof, and a spring 71 is connected to inner ends of the engaging pins 6, 6 at two ends thereof, and an axial rod 7 is passed through the spring 71, and movably passed into the engaging pins 6, 6 at two ends thereof. Detaining elements 65 are secured around inner ends of the pressed end portions 61 for lo preventing the pins 6, 6 from falling off. Thus, the engaging pins 6, 6 are biased away from each other by the spring 71. And, during downward movement of the engaging pins 6 together with the seat member 5 in connecting the rear part 12 to the front part 11, the pins 6 will be made to move in such direction as to compress the spring 71 owing to contact of cone-shaped portions 67, 67 thereof with the corresponding slopes 23, 23, and in turns, the engaging pins 6, 6 are passed through the gaps 22, 22 at thin portions 66, 66 thereof, and fitted in and engaged with the through holes 21, 21 at stopped portions 64, 64 thereof, as shown in Fig. 7. Consequently, the engaging pins 6, 6 will engage respective ones of the fitting portions of the locating seat member 2 after the connecting seat member 5 is fitted over the locating seat member 2. And, when the engaging pins 6, 6 are pressed at the pressed end portions 61, 61 thereof at the same time as shown in Fig. 8, the thin portions 66, 66 will be passed into the through holes 21, 21, and the engaging pins 6, 6 can be disengaged from the locating seat member 2; thus, the rear part 12 can be separated from the front part 11.
Referring to Figs. 1 and 9, the front part 11 of the frame further s has two fitting tubes 15 secured thereto, and a lifting handle 16 is detachably connected and pivoted to the front part 11 by means of inserting two fitting end portions 161 of the lifting handle 16 into respective ones of the fitting tubes 15; thus, one can lift the front part 11 easily by the handle 16 after the rear part 12 has been separated from the lo front pert 11.
Referring to Figs. 1 and 9 again, the fitting tubes 15 are further formed with connecting ears 151, and a strap 17 is connected to the connecting ears 151 at two ends thereof, and connected to a cover (not shown) of the cart frame 1 such that the frame cover is fastened to the frame 1.
From the above description, it can be easily understood that the present invention has advantages as followings: 1. The connecting seat member 5 can be easily fitted to the locating seat member 2 therefore the rear part 12 can be rapidly joined to the front part 11.
2. Connection of the connecting seat member 5 with the locating seat member 2 can be secured with the help of the fastening member 3.
3. The rear part 12 can be lifted at the front end for separating the connecting seat member 5 from the locating seat member 2 after the engaging pin 6 is pressed. Therefore, the rear part 12 can be easily separated from the front part 11.
4. Because of the lifting handle 16 joined to the front part 11, a person 5can lift the front part 11 easily after the rear part 12 has been separated from the front part 11.
