Embodiment
Now cooperate the graphic following preferred embodiment of enumerating, in order to structure of the present invention and effect are elaborated.
Please consult Fig. 1 and Fig. 2 earlier, be the supporting frame 10 of the present invention's one preferred embodiment.Supporting frame 10 includes a bearing table 20, a base frame 30, a supporting element 40, pair of links 50, a pair of driven subassembly 60, an actuator 70, and a pair of positioning component 80.
A toolroom machine (not shown) can be established in order to connect in the top of bearing table 20, and it is wherein a kind of that toolroom machine can be table saw machine, angle saw, scroll saw machine, Band saw machine, driling machine, skin grinder etc.Bearing table 20 has a first side 22, a second side 24, one the 3rd side 26 and a four side 28, and wherein, first side 22 has a pivot ear 221,241 respectively with the right ends of second side 24.
Please cooperate and consult Fig. 3, base frame 30 has two struts 32,34.The top of these struts 32,34 is hubbed at the pivot ear 221 of the first side 22 of bearing table 20 through a sliding sleeve 36, and the top of these struts 32,34 extends upward and interconnects and forms the grip part 302 that is available for users to grip; The bottom of each strut 32,34 be pivoted with one be resisted against ground roller 38, and the bottom of each strut 32,34 through bending and interconnect and form one can be supported in ground supporting portion 304.In addition, the stage casing of each strut 32,34 has one first pin-joint part 322,342 and one second pin-joint part 324,344, and wherein a strut 32 is provided with a clipping device 326 near the position of bottom; The centre of these struts 32,34 and bottom interconnect to increase the structural strength of base frame 30 through a cross bar 306 respectively.
Supporting element 40 has a pair of leg 40a, 40b, and each leg 40a, the top of 40b is hubbed at first pin-joint part 322,342 of each strut 32,34 and forms cross-over configuration with base frame 30, each leg 40a, the bottom of 40b then is resisted against ground.These legs 40a, 40b interconnects through a cross bar 44 in the position near the bottom, to increase these legs 40a, the structural strength of 40b.Wherein a leg 40a can be by 326 engagings of the clipping device of base frame 30, and in order to these legs 40a, 40b is positioned at the state that folds.
The two ends of each connecting rod 50 articulate second pin-joint part 324,344 of pivot ear 241 and each strut 32,34 of the second side 24 of bearing table 20 respectively.The bottom of each connecting rod 50 has a protuberance 52.
Please cooperate and consult Fig. 4, each driven subassembly 60 has a pivot 61, a driven member 62, a sleeve pipe 63, a torque spring 64 and a lining 65.Pivot 61 is arranged in second pin-joint part 324,344 of base frame 30; Driven member 62 is hubbed at the end of pivot 61, and has one first fixing part 66, a driven protuberance 67 and a stopper part 68 in abutting connection with first fixing part 66; Sleeve pipe 63 is sheathed on pivot 61; Torque spring 64 is set around sleeve pipe 63 and with its terminal driven member 62 that connects, certainly, torque spring 64 also can directly be set around pivot 61 and the design of omission sleeve pipe 63; Lining 65 is sheathed on pivot 61, and with sleeve pipe 63 mutual butts.
Actuator 70 has a treadle 72 and two side levers 74.These side levers 74 are articulated in each strut 32 of base frame 30 respectively; 34 second pin-joint part 324,344 and articulating each other with these connecting rods 50, the bottom of these side levers 74 is connected in the two ends of treadle 72; The top then is connected to these connecting rods 50; The distance of its top to this second pin-joint part 324,344 is less than the distance of its bottom to this second pin-joint part 324,344.The top of each side lever 74 has protuberance 52 that a recess 742 can supply connecting rod 50 in addition can supply first fixing part, 66 inlay cards of driven member 62 against, one second fixing part 744, and one drives the driven protuberance 67 that protuberance 746 is resisted against driven member 62.
Each positioning component 80 has a positioning seat 82, an elastic component 84 and positioning piece 86.Positioning seat 82 is fixed in second pin-joint part 324,344 of base frame 30, and has an appearance hole 822; Elastic component 84 is located at and is held in the hole 822, and ejection locating piece 86, forces locating piece 86 tops to support driven member 62.
When the user desired to fold supporting frame 10, the treadle 72 of trampling actuator 70 earlier forced actuator 70 to be switched to a stowed position P1.At this moment, the driven protuberance 67 that the driving protuberance of actuator 70 746 can promote driven members 62 pivots to drive driven member 62, and is as shown in Figure 5, lets first fixing part 66 of driven member 62 leave second fixing part 744 of actuator 70.When driven member 62 pivots; Driven member 62 can spur torque spring 64 to store the torsion of torque spring 64; And one first press face 682 of the stopper part 68 of driven member 62 can push locating piece 86 and make in its appearance hole 822 of submerging gradually, and after first press face 682 of stopper part 68 staggered with locating piece 86 fully, locating piece 86 can be released appearance hole 822 by elastic component 84 once more; And be resisted against one second press face 684 of stopper part 68; As shown in Figure 5, in order to location driven member 62, make driven member 62 can not receive the drive of torque spring 64 and pivot towards the direction of actuator 70.Thus, through two side levers, 74 interlocks, two connecting rods 50 of actuator 70, can be with the first side 22 of bearing table 20 strut 32 along base frame 30; 34 down slippages are pressed close to base frame 30 until the second side 24 of bearing table 20, at this moment; Bearing table 20 and on connect the center of gravity of the toolroom machine of establishing; Also, as shown in Figure 6 along with moving down, help supporting frame to divide a word with a hyphen at the end of a line stably and place with upright.When base frame 30 is pressed close in the second side 24 of bearing table 20; The bottom of connecting rod 50 will compress torque spring 64 and see through the stopper part 68 of torque spring 64 releasing driven members 62 and the block state between the locating piece 86; Through driving the direction pivot of driven member 62 towards actuator 70; Touch the side lever 74 of actuator 70 up to driven member 62, as shown in Figure 7.Then again with these legs 40a, 40b pivots towards base frame 30, lets leg 40a be stuck part 326 and blocks with completion and fold, and is as shown in Figure 8, and the user can hold grip part 302 and the rolling through these rollers 38, and supporting frame 10 is divided a word with a hyphen at the end of a line forward.
When desire is launched supporting frame 10, trample treadle 72 earlier and form a pivot track, through two side levers, 74 interlocks, two connecting rods, the 50 generation pivots of actuator 70; Make the first side 22 of bearing table 20 up slide onto the position of expansion, and remove the pressure that these connecting rods 50 are bestowed driven member 62 along the strut 32,34 of base frame 30; Driven member 62 will and force first fixing part 66 of driven member 62 to embed in second fixing part 744 of actuators 70 by torque spring 64 drives, and will be in order to actuator 70 is positioned an expanded position P2, as shown in Figure 4; At this moment; The second side 24 of bearing table 20 is to be propped up a predetermined altitude away from base frame 30 by these connecting rods 50, and is as shown in Figure 3, and the protuberance 52 of these connecting rods 50 will be resisted against in the recess 742 of actuator 70; Make bearing table 20 fixing no longer slippages, to accomplish the expansion of supporting frame 10.
Through this, supporting frame of the present invention has the good supporting effect, and only need can accomplish folding and launching of supporting frame through trampling actuator, and is quite convenient in the operation, can reach the purpose that increases convenience of use.
The above; Be merely the detailed description and the diagram of preferred embodiment of the present invention; All closing in the embodiment of the spirit variation similar of claim of the present invention with it; All be contained in the category of the present invention, anyly be familiar with this art in the field of the invention, can think easily and variation or modify the claim that all can be encompassed in following this case.
