- 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 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.

Abstract
A foldable bed has a joint, which has a main body, a block up and down movably fitted to the body, two supports pivoted to the body, and two plates; two rods of a frame of the bed are pivoted to the body; the block is biased to a lowermost position by a spring, and the bed can be folded only when the block is kept in a highest position; the supports will be made to engage the block by the rods immediately after the bed is stretched, thus preventing the block from moving to the highest position; the plates are co-movable with the rods, and can make the block kept in the highest position immediately after at least one rod part is folded; thus, after the block is moved to the highest position, the rods can be folded one after the other without having to operate the block twice.
Description
- 1. Field of the Invention
- 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.
- 2. Brief Description of the Prior Art
- Referring to
FIG. 12 , the applicant in the present application was granted U.S. Pat. No. 6,202,229 B1 on Mar. 20, 2001, which disclosed “A Joint Of A Foldable Bed For Babies”. The joint includes: -
- a main body 1 having a curved
top portion 13, twoside plates top portion 13, to which two adjacent ones of rod parts 4, 4 of a frame of a bed are pivoted at inward ends, andgaps 17 next to two ends of the curvedtop portion 13; - a pressing block 2 up and down movably held between the
side plates engaging trenches 22 on two sides facing respective ones of two ends of the main body 1; - a
spring 24 positioned between the topcurved portion 13 and a top of the pressing block 2 for biasing the pressing block 2 downwards to a lowermost position; and - two supporting
members side plates side plates member 3 having anengaging bar 32 on a first end for engagement with a correspondingengaging trench 22 on the pressing block 2; each supportingmember 3 having acurved portion 34 formed on a second end substantially in an opposite direction of the first end for supporting a respective one of the inward ends of the rod parts 4 on when the bed is in a stretched position; the supportingmembers 3 havingelastic plate portions 33 above theengaging bars 32 thereof.
- a main body 1 having a curved
- Thus, the supporting
members 3 will be tightly pressed on respective ones of theengaging trenches 22 at theengaging bars 32 thereof to prevent the pressing block 2 from moving as soon as the rod parts 4 are pressed against thecurved portions 34 of the supportingmembers 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 thespring 24, thus preventing the bed from folding. - And, to fold the bed, first 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 supportingmembers 3; thus, the supportingmembers 3 will pivot automatically so as to be away from theengaging trenches 22 of the pressing block 2, no longer stopping the pressing block 2 from moving up. Then, the pressing block 2 is manually pushed to a highest position such that the supportingmembers 3 are free to pivot. Finally, the rod parts 4 are angularly displaced relative to the main 1 body towards an upright position where the inward ends of therod parts 9 are the lowermost; thus the bed is folded. - The above joint of a foldable bed is found to have disadvantages as followings:
- 1. One of the rod parts 4 can still be left in the horizontal stretched position in folding the bed because of improper action of the user. And, the user has to first push the pressing block 2 to the highest position again before he pivots the left-horizontal rod part 4 to the upright position because the pressing block 2 has been biased to the lowermost position by the
spring 24 immediately after the user stopped pushing it. However, the user usually forces this rod part 4 to change angular position relative to the main body 1 without first pushing the pressing block 2. Consequently, the joint is damaged. - 2. Although supporting
members 3 are formed with thecurved portions 34 for contacting the curved sides of the rod parts 4, the inward ends of the rod parts 4 still can't contact thecurved portions 34 closely, and there is space in between. Consequently, the rod parts 4 are not steady enough when the bed is in the stretched position. - It is a main object of the present invention to provide a joint of a foldable bed for babies to overcome the above disadvantages.
- 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. Furthermore, the inward ends of the rod parts have plane bottom sides, and 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. 12 is an exploded perspective view of the prior joint of a foldable bed as described in Background. - Referring to FIGS. 1 to 3, a preferred embodiment of a joint of a foldable bed for babies includes a
main body 5, apressing block 6, two supportingmembers 7, twoplate members 8, and twoplug bodies 91, and is connected with two adjacent ones ofrod parts 9 of a frame of the foldable bed, which have radialpivotal holes 92 near to inward ends thereof for connection with the joint. Furthermore, each of therod parts 9 has aplug body 91, which is inserted in the inward end, and which has aplane contact bottom 911 outside therod part 9, and a throughhole 912 aligned with thepivotal hole 92. - The
main body 5 of the joint has acurved top portion 52, and two substantially parallel andopposing side plates 51, which extend downwards from thecurved top portion 52, and project beyond thecurved top portion 52 at two ends thereof. Theside plates 51 are formed with two pairs of fittingholes 511 along lower ends of middle lines thereof, two pairs ofpivotal holes 512 equidistant to the middle lines, two pairs ofpivotal holes 513 on upper corners, twofitting holes 514 under thepivotal holes 513 of a first one of theside plates 51, two throughholes 516 higher than thepivotal holes 512 on thefirst side plate 51, and two throughholes 515 higher than the throughholes 516 on thefirst side plate 51; thethrough holes 516 are farther away from the middle line of thefirst side plate 51 than thepivotal holes 512. Thecurved top portion 52 has aopening 522 on a middle thereof, two connectingholes 521 on two sides of theopening 522, and a locatingplate 523 fitted to theopening 522 and projecting downwards between theside plates 51. Protectingplates 57 are secured on thetop portion 52 by means of securingelements 56, which are passed through the protectingplates 57 as well as the connectingholes 521. - The
rod parts 9 of the frame are pivoted to themain body 5 by means ofpivotal posts 55, which are passed through thepivotal holes main body 5 and therod parts 9, and the throughholes 912 of theplug bodies 91 such that therod parts 9 can be angularly displaced relative to themain body 5 for the frame to change from a folded position, as shown inFIG. 6 , and a stretched position, as shown inFIG. 2 , and vice versa. - The
pressing block 6 has anupright slot 61 at a middle, twoengaging trenches 62 facing opposite directions, two stoppingprotrusions 63 under respective ones of theengaging trenches 62, two holding recesses (not numbered) above the stoppingprotrusions 63, and a locatingcavity 64 on a top side. Thepressing block 6 is up and down movably held between theside plates 51 of themain body 5 by means ofguide pins 53, which are passed through thefitting holes 511 of themain body 5, and theslot 61 of theblock 6; thus, theengaging trenches 62 are directed towards respective ones of the inward ends of therod parts 9. In addition, aspring 65 is positioned on the locatingcavity 64 at a lower end, and fitted to the locatingplate 523 at an upper end for biasing thepressing block 6 downwards to a lowermost position. - Each of the supporting
members 7 has apivotal hole 71, anengaging bar 72 at a first end, anelastic plate portion 73, and abearing side 74 formed on a second end substantially in an opposite direction of the first end. The supportingmembers 7 are pivoted to themain body 5 by means ofpivotal pins 54, which are passed through thepivotal holes 512, and thepivotal holes 71 thereof, so as to be beside thepressing block 6 with theengaging bar 72 facing a correspondingengaging trench 62. - Each of the
plate members 8 has a throughhole 81 at a first end, a contactingbump 82 on a first side of the first end, a locatingbump 83 also on the first side of the first end, arecess 84 over a middle portion of the first side, atouching bump 85 on a second end of the first side, and astopping bump 86 also on the second end of the first side; theplate members 86 are flexible because the middle portions thereof are thinner owing to the presence of therecesses 84. Theplate members 8 are positioned next to the outer side of thefirst side plate 51, and are connected to respective ones of thepivotal posts 55 of therod parts 9 at the throughholes 81 thereof with the locatingbumps 83 being passed into thefitting holes 514 of thefirst side plate 51, the contactingbumps 82 being pressed against thefirst side plate 51, and with thetouching bumps 85, and thestopping bumps 86 being respectively passed through the throughholes first side plate 51, as early mentioned. In addition, when the foldable bed is in the stretched position, therod parts 9 will touch the correspondingtouching bumps 85 such that the second ends of theplate members 8 are pushed outwards, and thestopping bumps 86 will retreat from the inner side of thefirst side plate 51 so as not to be obstacle to the supportingmembers 7 any longer. And, theplate members 8 are pressed against thefirst side plate 51 at the contactingbumps 82 thereof such that there is a small distance between the first ends of theplate members 8 and thefirst side plate 51, and the second ends of theplate members 8 are tightly pressed against thefirst side plate 51 with thetouching bumps 85, and thestopping bumps 86 projecting beyond the inner side of thefirst side plate 51. - Thus, referring to
FIG. 2 , when the bed is in the stretched position, and thepressing block 6 in the lowermost position, theplane contact bottoms 911 of theplug bodies 91 will be pressed against the bearingsides 74 of the supportingmembers 7 at the inward ends thereof owing to gravity and tension of cloth portion of the bed, and the supportingmembers 7 stopped from turning by thepressing block 6 with theengaging bars 72 being fitted onto, and pressed against theengaging trenches 62, and in turns, thepressing block 6 cannot be moved upwards, and therod parts 9 are stopped from pivoting downwards on thepivotal posts 55 by the bearingsides 74 of the supportingmembers 7; thus, the bed is prevented from folding. When the bed is in the stretched position, the inward ends of both therod parts 9 will be pressed against thetouching bumps 85 of theplate members 8 such that thestopping bumps 86 and thetouching bumps 85 are retreated from the inner side of thefirst side plate 51, as shown inFIG. 3 . - To fold the bed, referring to
FIG. 4 , first themain body 5 is slightly lifted such that theplane contact bottoms 911 of theplug bodies 91 move to a higher position to be away from the bearingsides 73 of the supportingmembers 7 together with the inwards ends of therod parts 9. Consequently, the supportingmembers 7 pivot automatically so as to be away from the engagingtrenches 62, no longer stopping thepressing block 6 from moving up, as shown inFIG. 4 . Then, thepressing block 6 is pushed upwards, which will be stopped from moving further up as soon as the stoppingprotrusions 63 thereof come into contact with the inward ends of the supportingmembers 7, on which the engagingbars 72 are formed, and thepressing block 6 is kept in the highest position; thus, the inward ends of the supportingmembers 7 are held in the holding recesses of thepressing block 6, and the supportingmembers 7 are free to pivot in such direction that the outward ends thereof, on which the bearingsides 74 are formed, move down. Then, themain body 5 is pressed so as to cause angular displacement of therod parts 9 towards an upright position where the inward ends of therod parts 9 are the lowermost; thus, theplug bodies 91 will make the outward ends of the supportingmembers 7 move down together with them; thus, the outward ends of the supportingmembers 7 are right under the stoppingbumps 86, and the inward ends of the supportingmembers 7 are right under those portions of thepressing block 6 that are formed with theengaging trenches 62; the stoppingbumps 86 will project beyond the inner side of thefirst side plate 51 again after therod parts 9 leave them. Consequently, the supportingmembers 7 are stopped from turning, and thepressing block 6 is kept in the highest position by means of the supportingmembers 7, as shown inFIGS. 6 and 7 . - Therefore, in folding the bed, in case the user only successfully makes one of the
rod parts 9 pass beyond the corresponding stoppingbump 86, and leaves theother rod part 9 in the horizontal stretched position in his first action, thepressing block 6 will still be kept in the highest position by one of the supportingmembers 7 that is related to the former one of therod parts 9. And, the latter one of therod parts 9 still can be easily pivoted to the upright position without any obstacle. In other words, there is no possibility of damage to the joint that could be caused when therod part 9 is forced to pivot to the upright position while being still locked with the joint. - Referring to
FIG. 9 , when the user moves a first one of therod parts 9 towards the horizontally stretched position after having made thefirst rod part 9 move to under the corresponding stoppingbump 86, thefirst rod part 9 will force the corresponding stoppingbump 86 retreat from the inner side of thefirst side plate 51 of themain body 5, and in turns, the stoppingbump 86 doesn't stop the corresponding supportingmember 7 any longer, and the supportingmember 7 is free to pivot with the outward end thereof moving upwards. And, thepressing block 6 will be made to move down to the lowermost position by thespring 65 immediately, and the corresponding engagingbar 72 will be pressed against the engagingtrench 62 of thepressing block 6 with the help of theplug body 91 of thefirst rod part 9, which is pressed against the bearingside 74 at theplane contact bottom 911 thereof. - To stretch the bed, referring to
FIGS. 2 and 10 , the user only has to lift themain body 5; while themain body 5 is being lifted, therod parts 9 will pivot so as to make the stopping bumps 86 retreat from the inner side of thefirst side plate 51 such that the stoppingbumps 86 won't stop the corresponding supportingmembers 7 any longer, and the supportingmembers 7 are free to pivot with the outward ends thereof moving upwards. And, thepressing block 6 will move down to the lowermost position immediately after the above actions, and the engagingbars 72 of the supportingmembers 7 will be tightly fitted onto the engagingtrenches 62 with the help of theplug bodies 91 of therod parts 9, which are pressed against the bearingsides 74 at theplane contact bottoms 911. Thus, the bed is stretched, and fixed in the stretched position. - Furthermore, the
plate members 8 can't turn on themain body 5 owing to the engagement of the locating bumps 83 with thefitting holes 514, and in turns, unwanted angular displacement of theplate members 8 are prevented after assembly. And, the contact between the contactingbumps 82 and thefirst side plate 51 will not only make the second ends of theplate members 8 tightly pressed against thefirst side plate 51 normally, but also will prevent errors in connecting thepivotal posts 55 to therod parts 9 as well as themain body 5, allowing therod parts 9 to be properly fitted to themain body 5. - From the above description, it can be easily understood that the present joint of a foldable bed for babies has advantages as followings:
- 1. The
rod parts 9 have the plane contact bottom sides 911 at the inward ends, and the bearingsides 74 of the supportingmembers 8 are plane therefore the inward ends of therod parts 9 can be steady on the supportingmembers 8 when the bed is in the stretched position. - 2. Because of the stopping
bumps 86 for the supportingmembers 7, in case the user only successfully makes one of therod parts 9 pass beyond the corresponding stoppingbump 86, and leaves theother rod part 9 in the horizontal position in his first action of folding the bed, thepressing block 6 will still be kept in the highest position by means of one of the supportingmembers 7 that is related to theformer rod part 9. Consequently, thelatter rod part 9 still can be easily pivoted towards the folded position without any obstacle, and there won't be any possibility of damage caused to the present joint by the angular displacement of thelatter rod part 9. - 3. In stretching the bed, the
rod parts 9 will pivot on themain body 5 so as to make the stopping bumps 86 retreat from the inner side of thefirst side plate 51 automatically. Consequently, the supportingmembers 7 are free to pivot with the outward ends thereof moving upwards, and thepressing block 6 will be made to move down by thespring 65 immediately for keeping the bed in the stretched position together with the supportingmembers 7. - 4. When the bed is in the stretched position, the
rod parts 9 will touch the corresponding touching bumps 85 to push the second ends of theplate members 8. Thus, the stoppingbumps 86 of theplate members 8 will retreat from the inner side of thefirst side plate 51 so as not to be the obstacle to the supportingmembers 7 any longer.
