Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates generally to a combination of a baby playpen and a baby bassinet, and more particularly to a baby playpen-bassinet combination in which a baby bassinet is safely and stably suspended from the top of a baby playpen by a simple and inexpensive mechanism.




2. Description of the Prior Art




Many types of baby playpen-bassinet combinations are currently available on the market. These baby playpen-bassinet combinations are different from one another mainly in the mechanism by which the baby bassinet is mounted onto the baby playpen.

FIG. 1

shows a prior art combination of a baby playpen


30


and a baby bassinet


40


. The baby playpen


30


includes an upper frame


31


, a bottom frame


32


, a supporting frame


33


and a fabric body


35


. The upper frame


31


are provided with four corner blocks


34


at four corners thereof. The supporting frame


33


connects corresponding corners of the upper frame


31


and the bottom frame


32


by being fixed to the corner blocks


34


. The fabric body


35


is supported by the upper frame


31


and the supporting frame


33


so as to surround the periphery of the playpen


30


and cover the bottom frame


32


. The baby bassinet


40


is formed by stitching a fabric


41


. The four corners of the bassinet


40


are cut away for mating with the corner blocks


34


of the playpen


30


. A number of hooks


42


are arranged along the top edge of the bassinet


40


. By hanging the hooks


42


of the bassinet


40


on the upper frame


31


of the playpen


30


, the bassinet


40


can be suspended from the top edge of the playpen


30


so that the bottom of the bassinet


40


is received within the playpen


30


.




With the bassinet


40


having the structure described above, since the hooks


42


have to be sufficiently strong in order to prevent from breakage during the use thereof, the hooks


42


are usually formed from plastic steel material which is relatively expensive. In addition, since the relatively rigid hooks


42


are connected with the much softer fabric


41


, after the bassinet


40


is used for a certain period of time, the fabric


41


often tears in the vicinity of the hooks


42


resulting in safety problems.




A baby playpen-bassinet combination developed to overcome the above mentioned problems in the prior art has been described in the U.S. patent application Ser. No. 09/632,148 filed on Aug. 3, 2000, by this inventor. Nevertheless, there still exits a need for a baby playpen-bassinet combination in which a baby bassinet is even more safely and stably suspended from the top of a baby playpen by a mechanism which is relatively inexpensive to manufacture.




SUMMARY OF THE INVENTION




An object of the present invention is therefore to provide a baby playpen-bassinet combination in which a baby bassinet is safely and stably mounted onto the top of a baby playpen by simple and inexpensive means.




To achieve the above object, the present invention provides a baby playpen-bassinet combination comprising a playpen including an upper frame, a supporting frame, a bottom frame and a fabric body, and a bassinet detachably mounted onto the upper frame of the playpen and including a main body, two suspension sleeve, two extension portions, two supporting rods, four coupling members and a bottom plate. The upper frame includes two horizontal longitudinal rods parallel to each other, two horizontal lateral rods parallel to each other and perpendicular to the two longitudinal rods and four corner blocks. Each of the four corner blocks fixedly connects one of the two longitudinal rods and one of the two lateral rods and is provided with a vertical hole and a vertically extending rib radially inwardly protruded from the wall of the vertical hole. The supporting frame is fixedly connected to the four corner blocks of the upper frame. The bottom frame is fixedly connected to the supporting frame. The fabric body wraps around the two longitudinal rods, the two lateral rods and the supporting frame so as to form a peripheral surface of the playpen and covers the bottom frame. The peripheral surface includes two lateral outer fabric sides extending downwards from the two lateral rods, respectively, and provided with first connecting means, respectively. The main body of the bassinet is received within a space defined by the two longitudinal rods and the two lateral rods of the playpen. The main body includes two longitudinal sides parallel to each other, two lateral sides parallel to each other and perpendicular to the two longitudinal dies and a bottom. The two suspension sleeves are connected to the two longitudinal sides of the main body so as to extend longitudinally, respectively. The two extension portions are connected to the two lateral sides of the main body so as to extend therefrom, respectively, and provided with second connecting means engageable with the first connecting means of the playpen, respectively. The two extension portions extend around the two lateral rods of the playpen, respectively, so as to be fixedly connected to the two lateral outer fabric sides of the peripheral surface of the playpen, respectively, through engagement between the first and second connecting means. The two supporting rods pass through the two suspension sleeves, respectively, so that two hollow end portions of each of the two supporting rods are protruded outside of the sleeve. Each of the coupling members has a horizontally extending first portion and a vertically extending second portion integrally formed with and extending downwards from an end of the first portion. The first portion is to be inserted into the hollow end portion of the supporting rod. The second portion has a radially inwardly recessed groove vertically extending upwards from a bottom thereof. The second portion is adapted to be inserted into the vertical hole of the corner block with the vertically extending groove engaging the vertically extending rib so that each supporting rod is supported on two corner blocks.




Preferably, the vertically extending rib and the vertically extending groove are located such that the vertically extending rib engages the vertically extending groove in a plane formed by the first and second portions of the coupling member when the second portion of the coupling member is inserted into the vertical hole of the corner block.




Preferably, the vertically extending groove is provided in the second portion of the coupling member on the same side as the first portion, and the second portion of the coupling member further comprises an resilient portion connected to the bottom of the second portion on an opposite side to the first portion and extending upwards from the bottom of the second portion in parallel with the second portion. The resilient portion is provided at a top thereof with a pressing portion obliquely extending to a level higher than that of the first portion so that pressing the pressing portion of the resilient portion causes the resilient portion to move towards the second portion of the coupling member, thereby facilitating the removal of the coupling member from the vertical hole.




Preferably, the corner blocks are formed from plastic or metal material, the supporting rods are formed from metal material such as iron and the coupling members are formed from plastic material.




The above and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the accompanying drawings, discloses a preferred embodiment of the present invention.

FIG. 2

is an assembled perspective view showing a preferred embodiment of the baby playpen-bassinet combination according to the present invention, and

FIG. 2

is an exploded perspective view showing the playpen-bassinet combination of FIG.


2


. As shown in

FIGS. 2 and 3

, the baby playpen-bassinet combination comprises a playpen


100


and a bassinet


200


detachably mounted on and suspended from the top of the playpen


100


and received within the playpen


100


.




The playpen


100


includes an upper frame


110


, a bottom frame


120


, a supporting frame


130


and a fabric body


150


. The upper frame


110


includes a first horizontal longitudinal rod


112


and a second horizontal longitudinal rod


116


parallel to each other in a longitudinal direction of the playpen


100


, a first horizontal lateral rod


114


and a second horizontal lateral rod


118


perpendicular to the first and second horizontal longitudinal rods


112


and


116


and parallel to each other in a lateral direction of the playpen


100


, and four corner blocks


140




a


,


140




b


,


140




c


and


140




d


for fixedly connecting two of the aforementioned horizontal rods, respectively. As shown in

FIGS. 2 and 3

, the corner block


140




a


fixedly connects the first longitudinal rod


112


and the first lateral rod


114


, the corner blocks


140




b


fixedly connects the first lateral rod


114


and the second longitudinal rod


116


, the corner block


140




c


fixedly connects the second longitudinal rod


116


and the second lateral rod


118


and the corner block


140




d


fixedly connects the second lateral rod


118


and the first longitudinal rod


112


. As well known in the art the rods


112


,


114


,


116


and


118


and the corner blocks


140




a


to


140




d


of the upper frame


110


may be formed from any suitable plastic or metal material. Furthermore, since the connections between the rods


112


,


114


,


116


and


118


and the corner blocks


140




a


to


140




d


are well known to those skilled in the art, they will not be further discussed or illustrated in detail herein.




The playpen


100


of the illustrated embodiment of the baby playpen-bassinet combination according to the present invention is different from the prior art playpen mainly in the structure of the corner blocks


140




a


to


140




d


. As best seen in

FIGS. 4A and 4B

, in this embodiment, the corner block


140




c


, for example, includes a longitudinal portion


142


extending in the longitudinal direction of the playpen


100


for fixedly connecting the second longitudinal rod


116


, a lateral portion


144


integrally perpendicularly extending from the longitudinal portion


142


in the lateral direction of the playpen


100


for fixedly connecting the second lateral rod


118


, and a protruded portion


146


integrally inwardly protruded between a lower portion of the longitudinal portion


142


and a lower portion of the lateral portion


144


. The protruded portion


146


is provided with a vertical hole


148


and a vertically extending rib


150


radially inwardly protruded from the wall of the vertical hole


148


. In addition, in this embodiment, the top portion of the protruded portion


146


is inclined downwards from a connecting portion


146




a


integrally connected to the lateral portion


144


to an edge portion


146




b


in the longitudinal direction of the playpen


100


, and the vertically extending rib


150


is inwardly protruded from the wall portion of the vertical hole


148


on the side of the edge portion


146




b


in a radial direction of the vertical hole


148


substantially in parallel with the longitudinal portion


142


. Moreover, as shown in

FIG. 4B

, in this embodiment, the vertically extending rib


150


upwardly extends slightly beyond the top of the edge portion


146




b


of the protruded portion


146


. This arrangement effectively prevents babies from intentionally or inadvertently inserting their fingers from above into the vertical hole


148


. Likewise, each of the corner blocks


140




a


,


140




b


and


140




d


is constructed in the same manner as the corner block


140




c


. Of course, it will be apparent to those skilled in the art from this disclosure that the vertical hole


148


may be a vertical blind hole or a vertical through hole. In the case of the vertical hole


148


being a blind hole, the vertically extending rib


150


may be integrally formed with and upwardly extend from the bottom portion of the vertical hole


148


. In the case of the vertical hole


148


being a through hole, it is desirable that the vertically extending rib


150


extends down to the lowest portion of the wall of the vertical hole


148


. This arrangement effectively prevents babies from intentionally or inadvertently inserting their fingers from below into the vertical hole


148


. Also, it will be apparent to those skilled in the art from this disclosure that the top portion of the protruded portion


146


may horizontally extend without any inclination, provided that they can achieve their functions which will be described in detail later. Of course, in this case, the upper end of the vertically extending rib


150


may be flush with rather than protruded beyond the top portion of the protruded portion


146


.

FIGS. 4A and 4B

also show a portion of one of the supporting rods of the bassinet


200


and a coupling member of the bassinet


200


for connecting the supporting rod and a corner block as will be described in detail later.




With reference to

FIGS. 2 and 3

again, the supporting frame


130


includes four vertical rods fixedly connected to the corner blocks


140




a


to


140




d


, respectively. The four vertical rods of the supporting frame


130


connect the upper frame


110


and the bottom frame


120


at respective corners by being fixedly connected to the corner blocks


140




a


to


140




d


. The bottom frame


120


may take any form, provided that it can be connected to the vertical rods of the supporting frame


130


to firmly and stably support the playpen


100


on the ground. Since the precise structure of the supporting frame


130


, the bottom frame


120


or the connection therebetween is not critical to the present invention, the structure of the supporting frame


130


or the bottom frame


120


will not be further described or illustrated in detail herein.




The fabric body


150


wraps around the horizontal rods


112


,


114


,


116


and


118


of the upper frame


110


and the vertical rods of the supporting frame


130


so as to be supported by the upper frame


110


and the supporting frame


130


to form the peripheral surface of the playpen


100


and to cover the bottom frame


120


. As shown in

FIG. 3

, the fabric body


150


wraps around the first and second longitudinal rods


112


and


116


to form the first and second longitudinal top edges of the playpen


100


, respectively, and around the first and second lateral rods


114


and


118


to form the first and second lateral top edges of the playpen


100


, respectively. Since the manner by which the fabric body


150


wraps around and is supported by the respective horizontal and vertical rods is well know to those skilled in the art, it will not be further discussed or illustrated in detail herein.




The peripheral surface of the playpen


100


, which is formed by the fabric body


150


, includes a first lateral outer fabric side


154


extending downwards from the first lateral top edge (i.e., the first lateral rod


114


) of the playpen


100


, and a second lateral outer fabric side (not shown) extending downwards from the second lateral top edge (i.e., the second lateral rod


118


) of the playpen


100


. As shown in

FIG. 3

, in this embodiment, as connecting means, five snap button female members


164


linearly aligned in the lateral direction of the playpen


100


are provided on the first lateral outer fabric side


154


at a position away from the first lateral top edge of the playpen


100


by a predetermined distance. Likewise, although not shown in the figures, five snap button female members linearly aligned in the lateral direction of the playpen


100


are also provided, as connecting means, on the second lateral outer fabric side at a position away from the second lateral top edge of the playpen


100


by the same predetermined distance. Of course, it will be apparent to those skilled in the art from this disclosure that the connecting means is not limited to the snap buttons, and any other connecting structure may be used to replace the snap buttons as connecting means. Also, it will be apparent to those skilled in the art from this disclosure that the number of the snap button female members is not limited to five but may be more or less, and the arrangement of the female members is not limit to be linear in the lateral direction of the playpen, provided that the function which will described in detail later can be achieved thereby.




Next, the structure of the baby bassinet


200

Likewise, the second extension portion


208


of the bassinet


200


is integrally connected at one edge thereof to the top edge of the second lateral side of the main body


210


with the other edge opposite to the connected edge being a free edge. Although not shown in the figures, in the vicinity of the free edge of the second extension portion


208


, five snap button male members linearly aligned in the lateral direction of the bassinet


200


and protruded towards the bottom


230


of the main body


210


when the second extension portion


208


is horizontally pulled outwardly of the bassinet


200


are also provided as connecting means engageable with the connecting means of the playpen


100


described above. As will be described in detail later when the bassinet


200


is mounted on the top of the playpen


100


, the five snap button male members

of the first extension portion


204


and the five snap button male members of the second extension portion


208


of the bassinet


200


engages with the five snap button female members


164


of the first lateral outer fabric side


154


and the five snap button female members of the second lateral outer fabric side of the playpen


100


, respectively.




The first supporting rod


212


of the bassinet


200


has two hollow end portions


212




a


. In addition, the size and length of the first supporting rod


212


are designed such that the rod


212


can pass through the first suspension sleeve


202


of the bassinet


200


easily with the two hollow end portions


212




a


thereof protruded out of respective ends of the sleeve


202


. Likewise, the second supporting rod
