BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a playard, and more specifically, to a playard using a height adjustment device to adjust the height of a bassinet therein in a horizontal way.
2. Description of the Prior Art
Conventional playards usually includes a frame body and a detachable bassinet hanging on the frame body that provides lying place for a baby so that a babysitter can take care of the baby with more convenience. The bassinet usually hangs on the four arm rails of the frame body via hook hangers, with constant but deeper depth. Although deeper depth for a bassinet provides higher security, bigger space or better sheltering for the baby lying inside, it also causes greater inconvenience for the babysitter-he/she must bend down excessively before he/she is able to reach and hold the baby.
There are also some bassinet designs that give the bassinet two-way depth (or height) adjustability by using zipper or other ways of coupling. When the bassinet is zipped up, it has shallower depth so that the babysitter can take care of the baby with more convenience. If the zipper is opened, the bassinet in turn has deeper depth so that bigger child can play inside or rest. Such design, however, provides only two depth alternatives, which means arbitrary depth adjustability is not attainable for such design. Furthermore, conventional bassinet can not maintain horizontal and steady during height adjusting and inevitably cause disturbance for the baby lying therein.
SUMMARY OF THE INVENTION
The present invention provides a playard. The playard comprises a frame body, two retainers, and a bassinet. The frame body comprises two first side panels, two second side panels, and one bottom panel connecting to the two first side panels and the two second side panels to form a containing room. The two first side panels have a first side rail and a second side rail respectively. The two retainers are mounted on the second side rail of the frame body. The bassinet is placed in the containing room of the frame body. The bassinet comprises a bassinet body and two adjustors. The bassinet body has a first side and a second side opposite to each other. Each of the two adjustors has a first end and a second end opposite to each other. The first end connects to the first side of the bassinet and the second end extends from the first side of the bassinet body toward and cross the first side rail, reaching to the bottom panel of the frame body and entering into the containing room of the frame body, and connecting to the second side of the bassinet body and coupling to the retainer. The adjustor is movable relative to the retainer such that the length of the adjustor locating inside the frame body is changed. When the length of the adjustor locating inside the frame body changes, the bassinet body changes its height relative to the frame body.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

DETAILED DESCRIPTION
Please refer to FIG. 1 and FIG. 2. FIG. 1 is an illustration of a playard 1 with a bassinet 5 that has height adjustability. FIG. 2 is an illustration showing the bassinet 5 of the playard 1 placed on the bottom of the playard 1 and has a mattress 7 to be put on. The playard 1 includes a frame body 10, a bassinet 5 mounted within the frame body 10, and two retainers 56. The frame body 10, in this embodiment, includes two long first side panels 101 opposite to each other, two short second side panels 102 opposite to each other, and a bottom panel 13 that connects to the bottom ends of the first side panels 101 and the second side panels 102 and the panels 101,102,13 form a containing room for a baby or the bassinet 5. On top of the two opposite first side panels 101 are a first side rail 11 and a second side rail 12 respectively and the bassinet body 51 of the bassinet 5 is height adjustable relative to the frame body 10 via a height adjustment device. As FIG. 1 and FIG. 2 show, the bassinet 5 comprises a bassinet body 51, two positioners 522, two adjustors 531,532, and a mattress 57. The height adjustment device includes the positioners 522, the two adjustors 531,532, and two retainers 56. The bassinet body 51, in this embodiment, includes a first side 511 and a second side 512 opposite to each other that are correspondent to the first side rail 11 and the second side rail 12 of the frame body 10 respectively, and a third side 513 and a fourth side 514 that are correspondent to the second side panels 102 respectively. To shape the bassinet body 51, the bassinet body 51 has two positioners 522 mounted on the upper portion of the first side 511 and the second side 512 respectively. In this embodiment, there are plurality of strengtheners 515 connecting between the first side 511 and the second side 512. The positioners 522 may pass through ring structures formed at the ends of the strengtheners 515 and can be removed from the bassinet body 51. In this embodiment, the positioners 522 are metal pipes so that the soft and flexible bassinet body 51 can be supported by the positioners 522, while in other embodiments, the positioners 522 can fix on the bassinet body 51 by other forms. FIG. 1 shows that the bassinet 5 locates inside the frame body 10. The first ends of the adjustors 531,532 connect to the positioner 522, which in FIG. 1 is hidden behind the soft goods of the first side 511, at the first side 511 of the bassinet body 51. The second ends of the adjustors 531,532 extend from the first side 511 of the bassinet body 51 upward and cross outward the first side rail 11 of the frame body 10, reaching to the bottom panel 13 of the frame body 10, shown in FIG. 3, and pass through an opening A, shown in FIG. 5, locating at the second side rail 12 so as to enter into the containing room of the frame body 10, and finally connecting to the positioner 522 at the second side 512 of the bassinet body 51, shown in FIG. 2 and FIG. 4.
Please refer to FIG. 4 and FIG. 5. FIG. 4 is an illustration showing an adjustor 532 of the bassinet 5 connecting to the second side rail 12 of the frame body 10 and FIG. 5 is an illustration of the adjustor 532 connecting to the retainer 56 with an adjusting belt 54. The retainer 56 is mounted on the second side rail 12 of the frame body 10 and in this embodiment, the retainer 56 can be detachably mounted on the second side rail 12 via a hook or other coupling device. The adjusting belts 54 can further be used to connect to the second ends of the adjustors 531,532 with one ends, where the second ends of the adjustors 531,532 connect to the positioner 522 at the second side 512 of the bassinet body 51 as shown in FIG. 4, and the other ends of the adjusting belts 54 pass through the retainers 56 that can fasten or release the adjusting belts 54. When the adjusting belts 54 move relative to the retainers 56, the length between the one ends of the adjusting belts 54 at the second ends of the adjustors 531,532 and the retainers 56 changes. Additionally, the adjustors 531,532 and the two adjusting belts 54 can be soft straps or other flexible soft goods. The retainers 56 in this embodiment is designed for allowing the adjusting belts 54 to move freely in only one direction and retaining the adjusting belts 54 in any position, and the retainers 56 must be released first before the adjusting belts 54 are able to move in opposite direction. In other embodiments, the adjusting belts 54 are movable relative to the retainers 56 only when the retainers 56 are released. The adjusting belts 54 can also be formed by the extension part of the adjustors 531,532. For example, after the adjustor 531, or the adjustor 532, forms a ring structure that connects the positioner 522 at the second side 512 of the bassinet body 5, the adjustors 531,532 extend upward and cross the second side rail 12 and connect to the correspondent retainer 56 respectively so that the structure is similar as the previous embodiment.
Please refer to FIG. 3, which is an illustration showing the bottom panel 13 of the playard 1. When the adjustors 531,532 extend from the first side rail 11 downward and cross the bottom panel 13 of the frame body 10, a plurality of supporters 14 mounted at the bottom panel 13, near the first side panels 101, and locating at the path the adjustors 531,532 cross, confines the adjustors 531,532 to move along a direction back and forth relative to the frame body 10 and separates the adjustors 531,532 from the bottom panel 13 of the frame body 10. The adjustors 531,532 are avoided to rub against the frame body 10 to be worn during moving.
The way how the adjustors 531,532 connecting to the bassinet body 51, passing through the frame body 10 and coupling to the retainers 56 maintains the bassinet body 51 in horizontal status during height adjusting. Please keep referring to FIG. 1 and FIG. 2. As FIG. 2 shows, when the bassinet body 51 needs to be adjusted higher toward direction U, or upward, to what is shown in FIG. 1 so as to easily hold the baby out of the bassinet 5, pulling the adjustors 531,532 toward direction D, or downward, shortens the section's length of the adjustors 531,532 locating inside the frame body 10, or in other words, the length of the adjustors 531,532 between the second side 512 of the bassinet body 51 and the retainer 56 is shortened. Since the adjustors 531,532 have constant overall length, the second ends of the adjustors 531,532 moving toward direction U causes the first ends of the adjustors 531,532 at the first side 511 to move the same distance. This ensures that the first side 511 and the second side 512 of the bassinet body 51 move the same distance toward direction U and the bassinet body 51 is kept horizontal when pulling the adjustors 531,532.
On the other hand, it only needs to release the retainers 56 to adjust the bassinet 5 to a lower height as shown in FIG. 2. The bassinet body 51 moves toward direction D because of its own weight and the bassinet body 51 is kept horizontal during movement until it moves to a desired position relative to the frame body 10. Locking the retainers 56 will stop the descending of the bassinet body 51. In such way, the bassinet body 51 and the mattress 57 thereon can be kept horizontal during height adjusting and can be lifted or lowered to an arbitrary height by user's need. Additionally, the retainers 56 can perform locking or releasing the adjustors 531,532 with separate operations or simply with one-step actuation, i.e., pressing the retainers 56 to release the adjustors 531,532 and auto-locking the adjustors 531,532 when releasing the retainers 56.
The playard disclosed in the present invention has a height adjustment device for the bassinet. The bassinet has adjustors with one ends connecting to the first side of the bassinet body and the other ends to the second side of the bassinet body. The adjustors extend from the first side toward and cross the first side rail of the frame body, reaching to the bottom panel of the frame body and into the frame body, and connecting to the second side of the bassinet body. The playard includes two retainers, each mounting on the second side rail of the frame body. Pulling the adjustors brings the first side and the second side of the bassinet body to move up or down by the same distance. The bassinet can therefore maintain horizontal and be adjusted to an arbitrary height during height adjusting.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
