## Background
BACKGROUND
A tent not only provides shelter but also provides a means for leisure and amusement. Conventional tents are typically opened and closed using cloth tubes, guide rails, and pulleys having a zinc die wheel frame with iron pieces, and bearings. This group of components comprising the zinc die wheel frame with iron pieces and bearings is complicated in structure, complicated in technical requirement, difficult to assemble and operate, and have high production costs. Moreover, during operation, conventional tents tend to break due to the fragile nature of the zinc die wheel frame, or the iron pieces become rusty. Therefore, in a conventional tent, if the pulling operation is not balanced, the pulling of a canopy of the tent will be difficult or obstructed, thereby making the conventional tent difficult to assemble.
Hence, there is a long felt but unresolved need for a tent apparatus that enhances the operation of opening and closing a canopy.

A first pair 102 of foot pipes 101 is opposably positioned with respect to a second pair 103 of foot pipes 101 in a geometric configuration, for example, a rectangular configuration, a square configuration, etc. A first beam member 104 is positioned perpendicular to the first pair 102 of foot pipes 101 and removably fastened to upper ends 101a of the first pair 102 of foot pipes 101. A second beam member 105 is positioned perpendicular to the second pair 103 of foot pipes 101 and removably fastened to upper ends 101a of the second pair 103 of foot pipes 101. The girders 106 are positioned perpendicular to the beam members 104 and 105, and removably fastened at predefined intervals 107 to the beam members 104 and 105. The girders 106 comprise internal guide rails 111 exemplarily illustrated in FIG. 2, that allow the pulleys 112 to rollably traverse the internal guide rails 111. In an example, the first beam member 104, the second beam member 105, and the opposing girders 106a and 106b form a generally square or rectangular ring beam frame. The cloth tubes 108 are, for example, hollow cylindrical tubes configured to carry a cloth element, where the cloth element is wound or slid around a circumferential wall of each cloth tube 108. The cloth tubes 108 are positioned perpendicular to the girders 106 and in sliding communication with the girders 106 via the pulleys 112. Each cloth tube 108 positions a canopy 109 in an accordion configuration 110. As used herein, “accordion configuration” refers to a configuration where the canopy 109 is folded around each cloth tube 108 similar to bellows of an accordion. The canopy 109 is fixedly attached to one of the beam members 104 and 105, for example, the first beam member 104, and in sliding communication with the girders 106. The canopy 109 is stretched across the upper ends 101a of the first pair 102 of foot pipes 101 and the second pair 103 of foot pipes 101 when the pulleys 112 are rolled within the internal guide rails 111 of the girders 106.
FIG. 2 exemplarily illustrates a front perspective view of a pulley 112 positioned in a girder 106 of the tent apparatus 100 exemplarily illustrated in FIG. 1. The girder 106 comprises internal guide rails 111 that allow the pulley 112 to rollably traverse the internal guide rails 111. The pulley 112 exemplarily illustrated in FIG. 2, comprises a handle 113 and wheel members 114, where a top portion 113a of the handle 113 is connected to a hub 114a of the wheel members 114.

The pulley 112 further comprises a receptor member disposed at a bottom portion 113b of the handle 113, for example, an opening 122 or a threaded bore hole 123 exemplarily illustrated in FIGS. 3B-3C, to receive and connect one of the cloth tubes 108 exemplarily illustrated in FIG. 1. In an embodiment, each pulley 112 of the tent apparatus 100 is made of a plastic material. For example, the pulley 112 exemplarily illustrated in FIG. 2, is made of plastic wheel members 114 with a plastic handle 113 extending outwardly from the hub 114a of the plastic wheel members 114. The pulley 112 is low in mass and cost effective because of the plastic material.
FIG. 3A exemplarily illustrates a partial front perspective of the tent apparatus 100, showing pulleys 112 in rolling communication with the internal guide rails 111 of the girders 106 exemplarily illustrated in FIG. 2. In an embodiment, the pulleys 112 comprise a central pulley 115, a rightmost pulley 117, and a leftmost pulley 119. The central pulley 115 is in rolling communication with a central girder 116. The rightmost pulley 117 is in rolling communication with a rightmost girder 118. The leftmost pulley 119 is in rolling communication with a leftmost girder 120. The central pulley 115 traverses the internal guide rails 111 of the central girder 116 to stretch the canopy 109 across the upper ends 101a of the first pair 102 of foot pipes 101 and the second pair 103 of foot pipes 101 exemplarily illustrated in FIG. 1. The pulleys 112 made of a plastic material are easy to produce on a mass scale, are resistant to breakage failure, have a long service life, and allow a blockage free pulling of the canopy 109. The quality and finish of the pulleys 112 are also easy to control during production. In an embodiment, the tent apparatus 100 disclosed herein further comprises a cloth pulling member 121 fixedly attached proximal to an edge 109a of the canopy 109. A user may hold the cloth pulling member 121 to pull and wind the canopy 109 over each of the cloth tubes 108.
FIG. 3B exemplarily illustrates an enlarged view of a portion marked A in FIG. 3A, showing a front perspective view of a pulley 115, and FIG. 3C exemplarily illustrates an enlarged view of a portion marked B in FIG. 3A, showing a front perspective view of an embodiment of the pulley 117. As exemplarily illustrated in FIG. 3B, the receptor member of the central pulley 115 is, for example, an opening 122 for receiving a cloth tube 108 positioned proximal to one of the beam members 104 and 105, for example, the second beam member 105 exemplarily illustrated in FIG. 1. As exemplarily illustrated in FIG. 3C, in an embodiment, the receptor member of the rightmost pulley 117 or the leftmost pulley 119 is, for example, a threaded bore hole 123 configured to fasten opposing ends 108a and 108b of the cloth tube 108 exemplarily illustrated in FIG. 3A, positioned proximal to one of the beam members 104 and 105, for example, the second beam member 105. In an embodiment, the opposing ends 108a and 108b of the cloth tube 108 are further fastened to the threaded bore holes 123 of the rightmost pulley 117 and the leftmost pulley 119 via fasteners (not shown), for example, screws and nuts.
In an example, the wheel members 114 of the coaxially arranged central pulley 115, the rightmost pulley 117, and the leftmost pulley 119 are positioned on the internal guide rails 111 of the central girder 116, the rightmost girder 118, and the leftmost girder 120 respectively, exemplarily illustrated in FIG. 2 and FIG. 3A, while one of the cloth tubes 108 positioned proximal to one of the beam members 104 and 105, for example, the second beam member 105, is connected to the threaded bore hole 123 of the rightmost pulley 117, inserted through the opening 122 of the central pulley 115, and then connected to the threaded bore hole 123 of the leftmost pulley 119. The cloth pulling member 121 attached to the edge 109a of the canopy 109, for example, the movable side or the free pulley side as exemplarily illustrated in FIG. 3A, is used to pull and wind the canopy 109 across each of the cloth tubes 108. A user can manually pull the central pulley 115 through the internal guide rails 111 of the central girder 116 across the upper ends 101a of the first pair 102 of foot pipes 101 and the second pair 103 of foot pipes 101 exemplarily illustrated in FIG. 1, to extend the canopy 109.
