Please consult Fig. 1 and Fig. 2 earlier, be the supporting frame that is used for facility 10 of a preferred embodiment of the present invention.Supporting frame 10 includes a bearing table 20, a pair of first leg 30, a pair of second leg 40, an axostylus axostyle 50, a connecting rod 60, an actuator 70, a pair of locating piece 80, a torque spring 90 and a damping device 100.
Please cooperate and consult Fig. 3, a facility (not shown) can be established in order to connect in the top of bearing table 20, and facility can be a kind of of woodworkers such as table saw machine, angle saw, scroll saw machine, Band saw machine, driling machine, skin grinder.Bearing table 20 is a framework, side frame 202, a back side frame 204, a left frame 206 and a right frame 208 before having one, the place ahead of wherein preceding side frame 202 is installed with a handle 22 and grips for the user, left and right side frame 206,208 are pivoted with a fastener 24 respectively, and each fastener 24 has a pulling part 242 and a hook part 244 that supplies the user to pull, and left and right side frame 206,208 have the chute 262 that a ring wall 26 and is located at this ring wall 26 and parallel left and right side frame 206,208 respectively.In addition, left and right side frame 206,208 are provided with the recess 28 of depression up in the rear end of each chute 262, and left and right side frame 206,208 then have a cushion block 29 respectively in the bottom edge with respect to chute 262, each cushion block 29 is apical margins (as shown in Figure 8) in order to be pressed against second leg 40 when each first leg 30 and second leg 40 are amounted to mutually, has the effect that buffering bearing table 20 presses down.
The top of each first leg 30 is hubbed at back side frame 204 two ends of bearing table 20, and the bottom of each first leg 30 then is resisted against ground.
The top of each second leg 40 is sheathed on the clipping device 44 (present embodiment is a pad) of pivot 42 and the left and right side frame 206 that a nut 46 that is locked on pivot 42 is hubbed at bearing table 20 by a pivot 42, that passes the chute 262 of bearing table 20, in 208 the chute 262, and each second leg 40 and each first leg, 30 cross-over configuration.The outer side surface lock of each second leg 40 is provided with a screw and forms an outwards outstanding protuberance 48, and the bottom of each second leg 40 then is articulated with a roller 49.
The two ends of axostylus axostyle 50 are hubbed at each first leg 30 respectively and pass each first leg 30 and articulate with each second leg 40.
Connecting rod 60 is a round bar, its two ends pass respectively bearing table 20 left and right side frame 206,208 chute 262 and be hubbed in the chute 262, and the two ends of connecting rod 60 form two mutual parallel sides 62 respectively.
Actuator 70 is sheathed on the right-hand member of connecting rod 60 and is positioned at ring wall 26 outsides of the right frame 208 of bearing table 20, an actuator 70 also can be set at left frame 206 and right frame 208 respectively, rotates in order to drive link 60.
Two locating pieces 80 have a perforation 82 respectively, each shape respective link 60 two ends of 82 of boring a hole has the section configuration of side 62, make two locating pieces 80 can be sheathed on connecting rod 60 two ends and be positioned at ring wall 26 inboards of the left and right side frame 206,208 of bearing table 20, and can be along with connecting rod 60 interlocks.Each locating piece 80 have an opening towards the locating slot 84 in the place ahead and by the outstanding stopper part 86 of locating slot 84 cell walls, wherein locating slot 84 root edges be shaped as circular-arc, just the clipping device 44 with circle cooperates, the clipping device 44 of each second leg 40 can be located in the locating slot 84, but the clipping device 44 of each second leg 40 of each stopper part 86 block and make it can't leave each locating slot 84 arbitrarily, and the inclined-plane 862 in each 86 outside, stopper part can slip into locating slot 84 smoothly for the clipping device 44 of each second leg 40.In addition, locating piece 80 is in being provided with one first tab 88a near perforation 82 positions, and locating piece 80 86 below is provided with one second tab 88b in addition in the stopper part.Each locating piece 80 can be pivoted by the driving of actuator 70 between a primary importance and a second place by connecting rod 60, when each locating piece 80 is positioned at primary importance, as shown in Figure 4, the clipping device 44 of each second leg 40 is blocked in the stopper part 86 of each locating piece 80, make each second leg 40 bearing table 20 pivots relatively, be positioned at the second place and work as each locating piece 80, as shown in Figure 6, the clipping device 44 of each second leg 40 can not blocked in the stopper part 86 of each locating piece 80, and each second leg 40 can also can be pivoted by simultaneously relative bearing table 20 along chute 262 slippage forward of bearing table 20.
When the user desires to fold supporting frame 10, compress actuator 70 downwards and make each locating piece 80 be switched to the second place by connecting rod 60, as Fig. 5, shown in Figure 6, each second leg 40 of this moment can slide onto chute 262 front ends of bearing table 20 forward and upwards pivot simultaneously, and each first leg, 30 same upwards pivot, damping device 100 will provide the strength of impedance, as shown in Figure 7, make bearing table 20 can reduce height reposefully, and the buffering of cushion block 29 that can be by bearing table 20 as press down the time, until each first leg 30 and each second leg, 40 close bearing table 20, as shown in Figure 8, then pull the pulling part 242 of each fastener 24 again, as shown in Figure 9, hook part 244 hooks that make fastener 24 are in the protuberance 48 of each second leg 40, thus, each first leg 30 folds Shi Buhui with each second leg 40 in supporting frame 10 and upsprings, and the user can mention handle 22 and pass through the rolling of each roller 49, and supporting frame 10 is divided a word with a hyphen at the end of a line forward.
When user's desire is launched supporting frame 10, pull the pulling part 242 of each fastener 24 earlier and make each hook part 244 break away from the protuberance 48 of each second leg 40, as shown in Figure 8, at this moment, damping device 100 will provide strength that the user can comparatively like a cork bearing table 20 be lifted, as shown in Figure 7, after bearing table 20 is lifted, the bottom of each first leg 30 is resisted against ground, each 40 of second leg slides onto chute 262 rear ends of bearing table 20 and the clipping device 44 of each second leg 40 is snapped in the locating slot 84 of each locating piece 80 and is positioned at primary importance, as shown in Figure 3, thus, each second leg 40 will be fixed in bearing table 20, make bearing table 20 be propped up a predetermined altitude.When supporting frame 10 was placed board or weight, the pivot 42 of each second leg 40 was the recesses 28 that are positioned at bearing table 20, produced pivot in order to prevent each second leg 40 because of the load that exceeds damping device 100 and locating piece 80.
Supporting frame of the present invention has preferable support effect, and need not pull down and can utilize comparatively easy and stable manner is finished and folded and launch, in order to increase the convenience in the operation.
The above; only be the detailed description and the diagram of preferred embodiment of the present invention; all closing in the embodiment of the spirit variation similar of the present patent application claim with it; all be contained in the category of the present invention; anyly be familiar with this skill person in the field of the invention, can think easily and variation or modify all be encompassed in the claim protection domain of the present invention.
