BACKGROUND OF THE INVENTION
Collapsible canopies that are capable of being locked into an unfolded position are very popular in modern society. Generally, each canopy comprises a foldable canopy frame and a canopy fabric, the canopy frame consists of a roof frame and four or more supporting legs, the supporting legs are used for supporting the roof frame and are generally provided with a locking structure on each supporting leg respectively, the canopy fabric covers the roof frame and is used for sunshading, rain sheltering or wind sheltering. The supporting legs are extendable to approximately twice their stowed length.
Collapsible canopies are utilized for shade and shelter purposes when the canopy is in an unfolded state. When it is time to move the canopy, the user will fold the collapsible canopy to a folded state so that it can be more easily transported. In the prior art the user will generally stuff the folded canopy into a transport bag. The transport bag usually has wheels so that the user can pull the canopy rather than having to lift it. Unfortunately, it can be time consuming and difficult to stuff the folded, collapsed canopy into the transport bag. Often the transport bag will rip and tear with age and usage.
What is needed is an improved collapsible canopy that allows for more efficient transportation of the collapsible canopy.
SUMMARY OF THE INVENTION
The present invention provides a wheeled collapsible canopy with foldable support frame. The wheeled collapsible canopy includes at least two wheeled legs and also at least two non-wheeled legs. A protective cover covers the top of the collapsible canopy when the collapsible canopy is in a folded state. The protective cover extends only partially down the length of the folded support frame.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1-9 show a first preferred embodiment of the present invention.
FIGS. 10-14 show a second preferred embodiment of the present invention.
FIGS. 15A-18E show a third preferred embodiment of the present invention.
FIGS. 19A-31 show a fourth preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION
FIGS. 1 and 2 show collapsible canopy 100 in a folded state. Feet 110 support canopy 100 upright as shown. To transport canopy 100, the user will tilt the canopy and pull it while walking. Canopy 100 will roll on wheels 118 of wheeled mechanism 115. Because two canopy legs include wheels 118 of wheeled mechanism 115, it is unnecessary to stuff collapsed canopy 100 into a transport bag having wheels. Instead only a much smaller protective cover is utilized. This greatly reduces the amount of time and work required to fold and then transport the collapsed canopy.
In FIGS. 1 and 2, protective cover 102 has been slid over the top of collapsible canopy 100. Protective cover 102 extends only partially down from the top of collapsible canopy 100. This makes it much easier to install and remove protective cover 102 from collapsible canopy 100. Strap 105 secures protective cover 102 on top of canopy 100. Strap 103 includes hook and loop fastener 104 for securing strap 5 as shown. Handle 103 permits a user to easily pull canopy 100 during transportation.
Horizontal feet 110 are welded to the bottom of extendable legs 111 to allow for greater stability of canopy 100. For wheeled legs 120 and for non-wheeled legs 119, spring loaded position locking clips 160 are rigidly connected to the bottom ends of outer leg sleeves 161.For both wheeled legs 120, wheel mechanisms 115 is connected to inner telescoping extendable leg 111 immediately above each foot 110. Wheel mechanisms 115 allow the user to tilt canopy 100 while canopy 100 is in its folded state. The user can then pull canopy 100 by grasping handle 103 and walking. Canopy 100 will then easily roll while supported by wheels of 118 of wheel mechanisms 115.
FIGS. 3-6 show detailed views of wheel mechanism 115. Wheel mechanism 115 includes wheel 118 rotatably connected via axle 131 to horizontal wheel bracket 132. Stabilizing brace 133 is rigidly connected to horizontal extension 132. Connection bolt 134 extends through horizontal wheel bracket 132 is secured by cotter pin 135.
FIG. 7 shows wheeled mechanism attached to the bottom of extendable leg 111 and positioned immediately above foot 110. To connect wheeled mechanism 115, the user inserts connection bolt 134 through hole 193 (FIG. 8) and secures connection bolt 134 with cotter pin 135 as described above.
In FIG. 7, spring loaded position locking clip 160 is connected to the bottom of outer leg sleeve 161. However, extendable leg 111 is not yet locked into position. To lock extendable leg 111 into position the user moves wheeled mechanism 115 upwards until opening 170 is aligned with knob 171. For example, in FIG. 9, for wheeled leg 120 and non-wheeled leg 119, opening 170 is aligned with knob 171, thereby locking extendable leg 111 into place as shown. It should be noted that locking clips 160 allow the user to lock into place the height of non-wheeled legs 119 so that they match the heights of wheeled legs 120, as shown in FIGS. 9, 1 and 2.
Second Preferred Embodiment
A second preferred embodiment of the present invention is shown in FIGS. 10 - 14. In the second preferred embodiment wheeled mechanism 115 has been replaced with wheeled mechanism 205. Wheeled mechanism 205 attaches to the bottom of extendable legs 207 for two of the extendable legs, as shown. Non-wheeled legs 210 include spring loaded position locking clips 206 to lock extendable leg 207 in position so that the height of non-wheeled legs 210 is equal to the height of wheeled legs 211.
FIGS. 12-14 show other views of wheeled mechanism 205. Horizontal support feet 410 each include an aperture for receiving wheeled mechanism 205. Wheeled mechanism 205 includes spring loaded push pin 208 for locking wheeled mechanism 205 into place into extendable leg 207.
Third Preferred Embodiment
A third preferred embodiment of the present invention is shown in FIGS. 15A-18E. In the third preferred embodiment wheeled mechanism 115 has been replaced with wheeled mechanism 225. Wheeled mechanism 225 attaches to the bottom of extendable legs 111 for two of the extendable legs to form two wheeled legs. As with the earlier embodiments, there are also two non-wheeled legs.
FIG. 15A shows an exploded view of wheeled mechanism 225. Wheeled mechanism 225 includes wheel bracket 905. Wheel bracket 905 is rotatably connected to foot 908 via axle 909.
