Definitions

  • the present invention relates to a joint of a foldable bed for babies, more particularly one, which is structured in such a way that damage thereto is prevented owing to improper actions of the user in folding and stretching the bed, and that rod parts of a frame of the bed, which are connected with the joint, will be more steadily held in position.
  • the supporting members 3 will be tightly pressed on respective ones of the engaging trenches 22 at the engaging bars 32 thereof to prevent the pressing block 2 from moving as soon as the rod parts 4 are pressed against the curved portions 34 of the supporting members 3 at the inward ends thereof owing to gravity after the bed has been stretched as well as after the pressing block 2 has been biased to the lowermost position by means of the spring 24 , thus preventing the bed from folding.
  • the main body 1 is slightly lifted such that the inwards ends of the rod parts 4 move to higher position to be away from the curved portions 34 of the supporting members 3 ; thus, the supporting members 3 will pivot automatically so as to be away from the engaging trenches 22 of the pressing block 2 , no longer stopping the pressing block 2 from moving up.
  • the pressing block 2 is manually pushed to a highest position such that the supporting members 3 are free to pivot.
  • the rod parts 4 are angularly displaced relative to the main 1 body towards an upright position where the inward ends of the rod parts 9 are the lowermost; thus the bed is folded.
  • the joint includes a main body, a pressing block, two supporting members, and two plate members.
  • the main body, the pressing block, and the supporting members are basically the same as those of the prior joint, and the plate members are fitted on the main body, and formed with stopping bumps for making the supporting members keep the pressing block in the highest position as soon as at least one of the rod parts of the frame is angularly displaced to the upright folded position; thus, in case the user only successfully moves one of the rod parts, and leaves the other rod part in the horizontal position in his first action of folding the bed, the pressing block will still be kept in the highest position, and the latter rod part still can be easily pivoted towards the folded position without any obstacle, preventing damage to the present joint.
  • the inward ends of the rod parts have plane bottom sides
  • the supporting members have plane bearing sides for supporting the plane bottom sides on; thus, the rod parts are more steadily held in position when the bed is in the stretched position.
  • FIG. 1 is an exploded perspective view of the joint of a foldable bed according to the present invention
  • FIG. 2 is a front view of the joint of the present invention
  • FIG. 3 is a top view of the joint of the present invention
  • FIG. 4 is a front view of the present joint, in folding action for the bed (step one),
  • FIG. 5 is a front view of the present joint, in folding action for the bed (step two),
  • FIG. 6 is a front view of the joint, after folding action of the bed
  • FIG. 7 is a side view of the joint, in folding action of the bed
  • FIG. 8 is a front view of the joint, when the bed is in partially folded position
  • FIG. 9 is a front view of the joint, while the pressing block is in the highest position after the bed is partially folded,
  • FIG. 10 is a front view of the present joint, when the bed is being stretched.
  • FIG. 11 is a side view of the present joint, when the bed is being stretched.
  • FIG. 12 is an exploded perspective view of the prior joint of a foldable bed as described in Background.
  • a preferred embodiment of a joint of a foldable bed for babies includes a main body 5 , a pressing block 6 , two supporting members 7 , two plate members 8 , and two plug bodies 91 , and is connected with two adjacent ones of rod parts 9 of a frame of the foldable bed, which have radial pivotal holes 92 near to inward ends thereof for connection with the joint. Furthermore, each of the rod parts 9 has a plug body 91 , which is inserted in the inward end, and which has a plane contact bottom 911 outside the rod part 9 , and a through hole 912 aligned with the pivotal hole 92 .
  • the main body 5 of the joint has a curved top portion 52 , and two substantially parallel and opposing side plates 51 , which extend downwards from the curved top portion 52 , and project beyond the curved top portion 52 at two ends thereof.
  • the side plates 51 are formed with two pairs of fitting holes 511 along lower ends of middle lines thereof, two pairs of pivotal holes 512 equidistant to the middle lines, two pairs of pivotal holes 513 on upper corners, two fitting holes 514 under the pivotal holes 513 of a first one of the side plates 51 , two through holes 516 higher than the pivotal holes 512 on the first side plate 51 , and two through holes 515 higher than the through holes 516 on the first side plate 51 ; the through holes 516 are farther away from the middle line of the first side plate 51 than the pivotal holes 512 .
  • the curved top portion 52 has a opening 522 on a middle thereof, two connecting holes 521 on two sides of the opening 522 , and a locating plate 523 fitted to the opening 522 and projecting downwards between the side plates 51 .
  • Protecting plates 57 are secured on the top portion 52 by means of securing elements 56 , which are passed through the protecting plates 57 as well as the connecting holes 521 .
  • the rod parts 9 of the frame are pivoted to the main body 5 by means of pivotal posts 55 , which are passed through the pivotal holes 513 , 92 of the main body 5 and the rod parts 9 , and the through holes 912 of the plug bodies 91 such that the rod parts 9 can be angularly displaced relative to the main body 5 for the frame to change from a folded position, as shown in FIG. 6 , and a stretched position, as shown in FIG. 2 , and vice versa.
  • the pressing block 6 has an upright slot 61 at a middle, two engaging trenches 62 facing opposite directions, two stopping protrusions 63 under respective ones of the engaging trenches 62 , two holding recesses (not numbered) above the stopping protrusions 63 , and a locating cavity 64 on a top side.
  • the pressing block 6 is up and down movably held between the side plates 51 of the main body 5 by means of guide pins 53 , which are passed through the fitting holes 511 of the main body 5 , and the slot 61 of the block 6 ; thus, the engaging trenches 62 are directed towards respective ones of the inward ends of the rod parts 9 .
  • a spring 65 is positioned on the locating cavity 64 at a lower end, and fitted to the locating plate 523 at an upper end for biasing the pressing block 6 downwards to a lowermost position.
  • Each of the supporting members 7 has a pivotal hole 71 , an engaging bar 72 at a first end, an elastic plate portion 73 , and a bearing side 74 formed on a second end substantially in an opposite direction of the first end.
  • the supporting members 7 are pivoted to the main body 5 by means of pivotal pins 54 , which are passed through the pivotal holes 512 , and the pivotal holes 71 thereof, so as to be beside the pressing block 6 with the engaging bar 72 facing a corresponding engaging trench 62 .
  • Each of the plate members 8 has a through hole 81 at a first end, a contacting bump 82 on a first side of the first end, a locating bump 83 also on the first side of the first end, a recess 84 over a middle portion of the first side, a touching bump 85 on a second end of the first side, and a stopping bump 86 also on the second end of the first side; the plate members 86 are flexible because the middle portions thereof are thinner owing to the presence of the recesses 84 .
  • the plate members 8 are positioned next to the outer side of the first side plate 51 , and are connected to respective ones of the pivotal posts 55 of the rod parts 9 at the through holes 81 thereof with the locating bumps 83 being passed into the fitting holes 514 of the first side plate 51 , the contacting bumps 82 being pressed against the first side plate 51 , and with the touching bumps 85 , and the stopping bumps 86 being respectively passed through the through holes 515 , 515 , and 516 , 516 of the first side plate 51 , as early mentioned.
  • the rod parts 9 will touch the corresponding touching bumps 85 such that the second ends of the plate members 8 are pushed outwards, and the stopping bumps 86 will retreat from the inner side of the first side plate 51 so as not to be obstacle to the supporting members 7 any longer.
  • the plate members 8 are pressed against the first side plate 51 at the contacting bumps 82 thereof such that there is a small distance between the first ends of the plate members 8 and the first side plate 51 , and the second ends of the plate members 8 are tightly pressed against the first side plate 51 with the touching bumps 85 , and the stopping bumps 86 projecting beyond the inner side of the first side plate 51 .
  • the pressing block 6 is pushed upwards, which will be stopped from moving further up as soon as the stopping protrusions 63 thereof come into contact with the inward ends of the supporting members 7 , on which the engaging bars 72 are formed, and the pressing block 6 is kept in the highest position; thus, the inward ends of the supporting members 7 are held in the holding recesses of the pressing block 6 , and the supporting members 7 are free to pivot in such direction that the outward ends thereof, on which the bearing sides 74 are formed, move down.
  • the main body 5 is pressed so as to cause angular displacement of the rod parts 9 towards an upright position where the inward ends of the rod parts 9 are the lowermost; thus, the plug bodies 91 will make the outward ends of the supporting members 7 move down together with them; thus, the outward ends of the supporting members 7 are right under the stopping bumps 86 , and the inward ends of the supporting members 7 are right under those portions of the pressing block 6 that are formed with the engaging trenches 62 ; the stopping bumps 86 will project beyond the inner side of the first side plate 51 again after the rod parts 9 leave them. Consequently, the supporting members 7 are stopped from turning, and the pressing block 6 is kept in the highest position by means of the supporting members 7 , as shown in FIGS. 6 and 7 .
  • the first rod part 9 will force the corresponding stopping bump 86 retreat from the inner side of the first side plate 51 of the main body 5 , and in turns, the stopping bump 86 doesn't stop the corresponding supporting member 7 any longer, and the supporting member 7 is free to pivot with the outward end thereof moving upwards.
  • the pressing block 6 will be made to move down to the lowermost position by the spring 65 immediately, and the corresponding engaging bar 72 will be pressed against the engaging trench 62 of the pressing block 6 with the help of the plug body 91 of the first rod part 9 , which is pressed against the bearing side 74 at the plane contact bottom 911 thereof.
  • the user only has to lift the main body 5 ; while the main body 5 is being lifted, the rod parts 9 will pivot so as to make the stopping bumps 86 retreat from the inner side of the first side plate 51 such that the stopping bumps 86 won't stop the corresponding supporting members 7 any longer, and the supporting members 7 are free to pivot with the outward ends thereof moving upwards.
  • the pressing block 6 will move down to the lowermost position immediately after the above actions, and the engaging bars 72 of the supporting members 7 will be tightly fitted onto the engaging trenches 62 with the help of the plug bodies 91 of the rod parts 9 , which are pressed against the bearing sides 74 at the plane contact bottoms 911 .
  • the bed is stretched, and fixed in the stretched position.
  • the plate members 8 can't turn on the main body 5 owing to the engagement of the locating bumps 83 with the fitting holes 514 , and in turns, unwanted angular displacement of the plate members 8 are prevented after assembly. And, the contact between the contacting bumps 82 and the first side plate 51 will not only make the second ends of the plate members 8 tightly pressed against the first side plate 51 normally, but also will prevent errors in connecting the pivotal posts 55 to the rod parts 9 as well as the main body 5 , allowing the rod parts 9 to be properly fitted to the main body 5 .
