The present invention relates generally to a playpen, and more particularly to a playpen with multiple columns, such as possessing double columns at each corner of the playpen.
DISCUSSION OF THE PRIOR ART A conventional playpen 3, generally of the kind disclosed in U.S. Pat. No. 6,539,563 B1 is shown in
Moreover, the conventional playpen 3, which is equipped with one pole at each nook or corner, needs poles with each possessing a larger diameter in order to meet requirements with respect to strength in construction, which make the conventional playpen 3 seem clumsy in appearance.
SUMMARY OF THE INVENTIONAccordingly, the present invention relates to a playpen equipped with double columns at each corner that are substantially intended to obviate one or more of the problems due to the limitations and disadvantages encountered in the prior art.
One object of the present invention is the provision of a playpen with columns which can provide a feeling of the structure abounding in a variety of materials.
Another object of the present invention is the provision of a playpen with columns which allows for the application of additional artificial decorations.
A further object of the present invention is the provision of a light and efficient playpen equipped with double columns at each corner.
Additional features and advantages of the invention will be set forth in the description which follows. The objectives and advantages of the invention will be realized and attained by the structure as particularly set forth in the written description and claims as well as illustrated in the appended drawings.
To achieve these and other advantages and according to the purpose of the present invention, as embodied and broadly described, the playpen with the double columns comprises: a plurality of first corners; a first rod unit connecting the first corners; a plurality of second corners; a second rod unit connecting the second corners; a plurality of first columns each having two opposite ends, one end being connected to the first corner, another end being connected to the second corner; a plurality of second columns each having two opposite ends, one end being connected to the first corner, another end being connected to the second corner; wherein the length of the two opposite second columns is larger than that of the two opposite first columns, and a gap exists between the adjacent first column and the second column and with a boundary sheet extending through each gap and covering the first columns.
In a preferred aspect, each second corner further comprises a first sleeve and a 20 second sleeve for respectively connecting with the first column and the second column.
Moreover, each first corner further comprises preferably a first bulge and a second bulge for respectively connecting with the first column and the second column. It is preferred that the columns respectively extend around the bulges.
It is another preferred feature that the playpen further comprises a plurality of rivets in order to secure the columns to respectively the first corners.
Additionally, the playpen further comprises a plurality of washers to secure the boundary sheet to respectively the ends of the first columns adjacent to the first corners.
It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory and are intended to provide a further non-limiting explanation of the invention as claimed.
BRIEF DESCRIPTION OF THE DRAWINGSThe accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a portion of the specification, illustrate embodiments of the invention and together with the description serve to explain the principle of the invention.

Thereafter, each first column 15 is respectively inserted downwardly into each first corner component 11 and washers around each first bulge 112. Then, a rivet 194 is respectively passed through the holes 114 of each first corner component 11 and the bore 151 of each first column 15 so as to connect each first column 15 with each first corner component 11. As far as the upper end of each first column 15, it is inserted into and secured by each first sleeve 122. Similarly, each second column 16 is respectively inserted downwardly into each first corner component 11 and washers around each second bulge 113. Then, a rivet 195 is respectively passed through the holes 114 of each first corner component 11 and the orifice 161 in each second column 16 so as to connect each second column 16 with each first corner component 11. As far as the upper end of each second column 16, it is inserted into and secured by each second sleeve 123. Having been assembled to this point, the rectangular frame shown in
