The pullout distance adjustable canopy leg 100 of the present invention includes an upper leg 200, a lower leg 300, and a gap limiting member 400.

Here, the canopy 10 mainly comprises a center post 20, a roof central frame 30, a roof frame 40, and a canopy bridge 100.

The upper legs 200 are installed in an upright position at each of four connected points of the roof frame 40, and hollow square pipes having an inner hollow are applied thereto. At this time, although the upper leg 200 is illustrated as having a square pipe shape, a circular pipe or the like is also applicable.

A slit-shaped hole 220 is formed on one side outer wall of the upper leg 200 and a rotary member 230 is installed in the hole 220 to move up and down by a spiral shaft 234.

The holes 220 are formed in the bending portion and bend the opposed opposite ends in the longitudinal direction so that both ends of the spiral shaft 234 are fixed.

The rotation member 230 is formed in a cylindrical shape, and a hooking groove 232 is formed on the outer circumferential surface at a set interval, and a spiral is formed on the inner circumferential surface of the hole so that the inner circumferential surface can be screwed onto the spiral shaft 234.

As a result, the rotatable member 230 can be used to fix the ring of the canopy tent to the canopy for the first time purchasing the canopy, or to separate the canopy from the canopy for washing of the canopy tent, 232, it can be moved upward to reduce the tension of the canopy tent, so that the hook can be easily fixed or separated into the catching groove 232.

The spiral shaft 234 is coupled to the rotary member 230 with both ends thereof inserted into the opposite surface holes of the hole 220.

The lower leg 300 is protruded and retracted while being inserted into the upper leg 200. A groove 310 is formed on one side of the outer wall except for both ends, Directional rack 320 is installed.

3 to 7, the gap limiting member 400 may be installed at a lower portion of the upper leg 200 to limit the movement interval so that the lower leg 300 is partially lowered at some intervals, and the lower leg 300 The movement of the lower leg 300 is not restricted.

To this end, the gap limiting member 400 includes a shaft portion 410, a push button 420, an elastic member 430, a ratchet wheel 440, and a brace 450.

The shaft portion 410 is a shaft disposed in the transverse direction and passes through the lower portion of the upper leg 200. The shaft portion 410 is moved by the pressing distance when the pushbutton 420 is pressed and by the restoring force of the elastic member 430 when the pressing force is released Move to home position.

And the shaft portion 410 is formed with a step 412 extended on the reference right side of FIG.

The push button 420 is formed to be able to protrude and retract within a hole formed in a lower one side wall of the upper leg 200 and to have an end bent so as not to be detached from the hole.

Further, the push button 420 is fixed to one end of the shaft portion 251, and can be screwed to one end of the shaft portion 410.

The elastic member 430 is provided between the step 412 of the shaft portion 410 and the lower inner side wall of the upper leg 200 facing the step 410 and presses the push button 420, 410) are moved to the home position.

6, the ratchet wheel 440 includes a first ratchet 442 mounted on the shaft portion 410 and having a tapered surface and a vertical surface formed radially on the outer surface, And a second ratchet 444 integrally formed on the left side of the first ratchet 442 and opposite in direction to the teeth of the first ratchet 442.

The ratchet wheel 440 functions to allow the lower leg 300 to be coupled with the second ratchet 444 by a distance corresponding to the distance between the starting point of the inclined surface of the second ratchet 444 and the lower end of the vertical surface.

Therefore, the first and second ratchet pawls 442 and 444 of the ratchet wheel 440 can be changed in accordance with the number of teeth, so that the minimum draw-out distance of the lower leg 300 can be adjusted.

The first ratchet 442 is spaced apart from the rack 320 and is provided in an interference state with the latch 450 provided on the inner wall surface 210 of the upper leg 200. [

When the shaft portion 251 is moved to the right by the push button 420, the second ratchet 444 is disengaged from the rack 320 and the upper leg 200 In a state in which they are interfered with the latch 450 provided on the inner wall surface 210 of the main body.

When the lower leg 300 is pulled out from the upper leg 200, the inclined surface of the first ratchet 442 is in close contact with the inclined surface of the rack 320 installed on the lower leg 300, 442 are rotatable in the clockwise direction and the latch 450 is hooked on the inclined surface of the second ratchet 444 when the second ratchet 444 is interlocked with the lower ratchet 444, 200).

However, when the lower leg 300 is retracted, the vertical surface of the rack 320 is caught by the tooth-shaped vertical surface of the second ratchet 444, and the tooth-like vertical surface of the first ratchet 442 is caught by the catch 450, 442 can not be rotated and finally the second ratchet 444 is also prevented from rotating so that the lower leg 300 can not move into the upper leg 200.

The latch 450 is rotatably mounted on the inner wall surface 210 of the upper leg 200 adjacent to the first and second ratchet 442 and 444 so that the ratchet wheel 440, The rotation direction is restricted so that the rotation direction is limited to only the direction.

Further, when the torsion spring (not shown in the drawing) is provided on the shaft and the ratchet wheel 440 rotates, when the ratchet wheel 450 passes the apex of the toothed inclined surface, the restoring force of the torsion spring acts, And is moved to reach the starting point of the inclined surface connected to the lower end of the vertical plane.

At this time, one end of the torsion spring may be supported by the latch 450 and the other end may be supported by the inner wall surface 210 of the upper leg 200.

The pawl 450 has an angle of rotation limited by a stopper (not shown in the figure) provided on the inner wall surface 210 of the upper leg 200 and has an end connected to the lower end of the tooth vertical surface of the ratchet wheel 440 It can be rotated to the starting point position.

Therefore, the operation of the pull-out distance-adjustable canopy leg 100 of the present invention is as follows.

First, the user grasps the lower leg 300 of the canopy leg 100 and draws it from the upper leg 200 by a predetermined distance.

The first ratchet 442 is not interlocked with the first ratchet 442 because the tooth sloped surface of the rack 320 installed on the lower leg 300 contacts the tooth sloped surface of the second ratchet 444 when the lower leg 300 is lowered, Even if the first ratchet 442 is interlocked in the clockwise direction, the toothed inclined surface of the first ratchet 442 is caught by the latch 450 so that the first ratchet 442 is also rotatable.

In this state, when the lower leg 300 is pushed into the upper leg 200, the tooth-shaped vertical surface of the rack 320 is brought into close contact with the tooth-shaped vertical surface of the second ratchet 444 to rotate the second ratchet 444 counterclockwise The vertical surface of the fixed first ratchet 442 is caught by the latch 450 and the first ratchet 442 is not rotated. As a result, the first ratchet 442 is not rotated, and the second ratchet 444 installed on the first ratchet 442 is not rotated. Thus, the lower leg 300 having the rack 320 fixed thereto can not be lifted.

Next, when the ground is not flat and a gap with the bottom surface of the lower leg 300 is formed, the lower leg 300 formed with the gap is pulled by the height corresponding to the gap with the ground so as to be brought into close contact with the ground surface.

In this way, even if the ground is not flat, the distance of each lower leg 300 can be adjusted by the distance of the crown of the rack 320, so that the horizontal adjustment of the canopy is possible.

On the other hand, the rotary member 230 is installed in each of the end portions of the canopy tent in order to fix the ring of the canopy tent to the canopy for the first purchase of the canopy, to separate the canopy from the canopy for washing of the canopy, 232, the rotating member 230 is rotated in the direction of the canopy tent or the opposite direction, and the hook of the canopy tent is hooked or separated to the catching groove 232 formed on the outer circumferential surface.

When the user pushes the push button 420 to move the lower leg 300 of the canopy leg 100 into the upper leg 200 in order to collapse the canopy, The second ratchet 444 of the ratchet wheel 440 fixed to the ratchet wheel 440 is separated from the rack 320 so that the lower leg 300 can be pulled in. However, the pulling length of the lower leg 300 can be made longer.

When the push button 420 is depressed by the user in a state where the lower leg 300 is pulled into the upper leg 200, the shaft 410 is positioned by the restoring force of the elastic member 430, The ratchet 444 is moved toward the rack 320 of the lower leg 300 to restrict the lower leg 300 from being pulled out.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.
