Description of the Invention: [Technical Field] The present invention relates to a balance arm that is maintained in an equilibrium state and which can support a supporting object. [Prior Art] A biasing support has an effect of being easy to move. Objects are as follows: 刖^Multiple cases; the structure that has been disclosed in the arm-to-field is used in a place where there are many ft-spreading sizes, heavy ri-connected, and can be used to adjust to support computer monitors or the like. mouth. In all 14 arm structures, the fresh=(four)-like print: the position of one or f-arms makes it support fixed: in two; =匕: can be set in a large range of two = fixed J is relatively heavy. Therefore, the technical field of "the development of the species - can hold the object at any equilibrium position = the minimum movement force when the change is arbitrarily changed, it is required to support the object when - ΐ ΐ ΐ decrease when it is non- It is very difficult to use this kind of arm to deal with this variable torque. Fine, there is design, a parallelogram-shaped arm structure, with an elastic Wei or extended object Provide the balance needed to adapt to the force required to support the object, so this kind of elastic cyanine = one =, -1307753 upper 疋 effective but 疋 'spring in the elastic range is proportional to the elastic coefficient. Because of, the wood to the surname When the force is to be moved within, the range of angles of the fixed length should be supported by the heterogeneity of the object ^; the linear resistance of the rail plus can not be specifically designed to support a given Heavy, and the net is still available.

The amount of support under 10 Heng "A lot of questions and ideas make sense i design and manufacturing is once balanced support arm:. : The more important idea is to consider that the balance arm must support different weights, and you must use a variety of different elastic coefficients of 3 ίίϊ. But 'obviously, this design is implemented = miscellaneous. For example: the manufacturer must keep all the spring stocks that may be used. Another design is that power is often used to support the vertical crossing of the support arm' to affect the aesthetics of the arm, and the moon will interfere with the arm's Wei. There are also many designs. Each division is set on a parallelogram formed by a strip, but this is a matter for the user. Ten households: Obviously, the industry needs a truly obedient arm structure, which moves at the same time in a wide range. Angle, the second support arm can adapt to changes. In addition, the 'compliant arm structure needs to adapt to different weights', and it is also necessary to avoid the danger of the operator exposing or damaging the wires. Step by step, the compliant arm structure must meet the aforementioned needs and have the advantage of representing significant advantages in the field. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above-mentioned deficiencies, and to avoid the lack of a storage arm, which can provide a balance between the support angles of the objects at a large angle of support, and the balance of the support is 1307753. Providing the generated torque arm non-linear change phase is sufficient for the support arm. The arms are moved between the equilibrium positions to balance the arms. The purpose of using non-M, the strength of the body, is to provide a kind of support for different weights for the above purposes, the present invention - two support arms, including the end and far "this ΐ contains at least pieces i at least two bomb * structure, its - end of the arm ί end of the end of the connector, the other end is connected to the upper side of the upper two supports at least two pivoting shaft, the phase is set at ± ^ authorized remote And one end. 疋-Support #运端和弹簧结构 [Embodiment] Please refer to the "Bai 2 and Figure 3", the rear eight... the cross-sectional view of the inferior arm, the second support arm of the present invention is A schematic diagram of the balanced motion of the flat arm of the present invention. As shown in the figure and the second support arm connection (4) of the present invention, at the same time, two of the two, in the second support and the second control arm 3G, the end of which is pivotally connected to the control arm The 28 end is pivotally connected to the intermediate connecting member 16. On the other side of the connecting member 8, the distal pivoting shaft 46 is pivotally connected to the distal end of the distal end 28 of the second supporting arm 28 via the pivoting shaft 50. The first control arm 18 is on the distal end member 16 of the second control arm 3Q. Therefore, the first control arm 28 and the = control are connected. The arm connector 18 and the intermediate connector 16 f - control the 彳 30 弟 2 support 48, 50 defined parallelogram structure. 戍 - by the pivoting car by 44, 46, in the illustrated embodiment, the second spring 24 For the roll-type elastic cyanine, by its 7 1307753 到 to the first control arm 28, and the end 47 of the second spring 24, the end of the east member 18, the end 47 of the al is not directly connected to the second support arm pull 32 The end is connected to the distal end of the coupling member 34, and the coupling member is coupled to the face of the pivotal chain 36. The hinged end of the pivotal chain is pivotally connected to the second support arm connector 18. By pivoting the shaft 44 = the pivoting range, and thus the pivoting axis], over:::^m 37 $Fucai 28, to prevent the separation of the two, the slogan provides the necessary support in the support arm 12. Second The support arm 24 is 12 related elements / control (four) 28 and the first - controller 3 (four) and the second support arm member 20. Although the end is pivotally connected to the upper arm 4 through the pivot link 64 - in the u read the money control However, the connector of the present embodiment is in the upper arm connection structure', thereby verifying the uniformity of the upper arm and the parallelepiped member 16 and the supported object & relative The inter-connecting structure, the parallelogram joint corresponding to the first-supporting arm holding f12 can maintain the kinetic k-branch connector 18 and the support surface (not shown), and the arm ^^=26 is also wound The spring can be held by the pivoting shaft 57 on the upper arm cover 55. The first spring 8 7753 and the coupling member 56 can be pivotally connected to the pivot wire 5? and the first connection is selectively connected through a Or a plurality of connecting slots 66A '66B ' 66c or other methods, the slider (four) puts the face of the heart to check the two trees - the branch, if the material is used for better stability, compared to the first use of "Τ 4, use In the case of an additional support arm, it can be indicated. In the second picture, the first control arm is used to find 38 to the distal pivoting axis 49. The second: j:=Temple/12 from the end_connected axis to the vertical line in the _〇 degree range to the first corner - α support == The relative (10) dependence will apply a moment or be applied to the end frame such that it reaches the first connecting groove 42A and extends Δ0. When the second bomb is set up, it will form a change in the original elastic rotation range. In the zone Jne)i, the two pivotal shafts 44 of the support arm 12 are supported. Therefore, the elastic force s f two bullets 24 effectively pivoted to a distance dl between and 46. Wonderful: The torque arm rotates the pivoting shaft 44 to the blocking surface 4〇U, and when the f is given the insertion angle, the pivotal chain 36 will step through the frame: the belt stops (= pivoting. The (4) 45 _ of the key 36, and the elastic force s acts on the ^^2284 1307753, especially the distal end 45 of the chain 36 and the pivot axis 46 are sorrowful. The value of the distance d2 is greater than the distance. Dl. Supports ^2, 4, 5, and 6" is shown in the first assembly diagram of the present invention, the pivotal structure of the present invention, and the 1^ positional support arm 12 is disposed in the vertical position. Second Ancient 1: The branch/Temple arm rotates to the second position of the end of the zone (z〇ne) 1, three dn2—turns from the vertical line along the zone n through the 90 degree second arm Ά The initial length of the second spring 24 is SL0 when the position is turned, and when the third turn is turned to the second position, the pivoting shaft 44 and the second spring 24 ί su = 2 leads 4 to 4, and the second is extended to the second position The torque generated by the flocking body 24 is gradually increased, and the force yellow 24 is pivoted to the distal end 45 of the pivotal chain 36, and not only the spring file is changed, but also the extension mode of the second elastic cyanine 24 is made. Two bombs i increase 绕 around the hub 44 The amount of elongation extended during continuous pivoting is more tangible to the above-mentioned chain 36, but the step of the balance arm is corrected. For example, in Fig. 5, the joint member passes through the -36Α, the first pivotal connection. The chain 36β and the third pivotal chain 36c are connected to the first "connecting member 18, where the first pivoting link, the second pivotal link minus the second framed key are a key chain, and are capable of pivoting the shaft. 39 given rotation = move to stop face division touch, Pei. More field first support | 12 when leaving the vertical position, will pass through the first zone, ϋ 2ί will effectively end around the first pivot key The handle rotates. At a given pivot, the younger pivotal link 36 pivots into contact with the first stop surface 4〇α, the second and second enters the second zone, and the second spring 24 wraps around the second pivotal chain 36. The second pivotal chain 継 abuts against the second blocking surface. After entering the three soil belts, the first spring 24 pivots effectively around the end of the second pivoting chain 36B. When the first 1307753 abuts the third blocking surface, enters The fourth=24 is different from the distal end of the third pivotal button 36C. FIG. 6 is another embodiment of the present invention. The pivotal connection 锸qR, 7丄L, and the ligature symbol 12 are pivoted about the pivot axis 38. The pivoting, moving 6-proportion method gradually abuts against the blocking surface 40, and the resulting "speeding" is shown in the "balanced section" of the present invention. The coupling member 56 of the first FIG. 1 is connected to the pivoting joint 57 and the shaft 57 is operatively connected to the intermediate connecting member f. The pivoting shaft 57 is disposed at the pivoting connection. The pivot shaft 57 is pivotally connected to the upper arm cover 55 of the intermediate link 14 and pivotally pivoted about the pivot shaft 58 to control the W 52 $ ^ ^ ^ ^ ^ ^ frame joint shaft 58 moves, The torque arm of S turns at the first ϋ ί. As discussed below, the 'elastic force tends to wrap around the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The moment arm of the first arm of the elastic force S is the pivot and red position. In position but in position 2, because the robes are connected to the vertical distance of the sleeves 58, the torque arm is reduced _ the shaft ^ = upper # cover body 55 crane, the elastic force S is at the position 3, the frame is connected to the shaft 57] f^58 _ Straight distance, finally, the moment arm is reduced to the further movement of the splicing shaft 55, the vertical distance d3 of the shaft 57 of the elastic force S and the abutment shaft 58. 1307753 Small to: the torque of the sauce j is equal to the torque arm, and the torque arm is reduced from dl by 9 = the tendency of the connector 16 to support the straight position of the arm when the pivoting is within the dry circumference. Making the first spring 26 f ° when the first support arm 14 is in the near horizontal position or 90 ΐ the first branch 26 applies the foot_torque to the balance, and also holds the excess of the #14 at the position 3 close to (10) degrees. Torque. The end 47 of the second magazine 24 is attached to the sliding connector 32 at any one or more of the links /, 2B' 42C' or other having a variable length SL0, SL1, SL2 51. Similarly, the end of the first spring 26 is connected to any one or more of the connection grooves 66, 66, 66C, or other connection point having a variable elastic length SU'SL4' SL5. The balance arm 10 can properly hold the support 22 in an equilibrium position. In fact, within a given range, the second spring 24 and the first spring 26 can selectively connect the ends of the sliding links 32 and 54 to support different weights of the support 22. For example, a given second spring 24 can be coupled to the sliding link 32 via the first connecting slot 42A to support a given weight of the supported object 22, as such, the second spring 24 can be sunk through the second connecting slot 4. Or the third connecting groove 42C is connected to support the weighted support π. Manufacturers, assemblers can make balance arms 10' that are specifically used to support different weights of support 22 and can use the few different springs. The embodiment of the balance arm 10 can be used to support almost any object, such as the two-arm embodiment of the balance arm 1 第 in Figure 8, the support 22 can be an amplifying lamp, since the wire 7 must be used as an amplifying lamp Providing electric power, the electric wires 7 〇 can pass through the inner space of the arm cover body 35 and the upper arm cover body 55 which are firmly held by the second support arm 12 and the first support arm 14, so that the balance arm 1 美 is aesthetically pleasing, And can provide practical power for the amplified light. In this embodiment, the balance arm 1〇 itself is placed on a table, chair, counter or any other flat 12 1307753 by a lost device 68, and the clamping device 68 is rotatably coupled to the first balance ΐ〇m10 It can also be a one-arm structure as shown in Fig. 9. Here, the second support arm 12 is supported by the support 22, the two support arms 12 are equally moved on the support surface, and the electric wire 70 can be mounted on the first iim arm 1 〇 can be clamped by the clamping device 68 fixed. >Reading Figure 0 is a broadcast of the balance arm of the present invention; 4 10 Contact the second bullet 72, it can be more suitable for the arm ^ = ^ ^ away from this balance 亍 ί , 『 『 『 『 『 『 『 『 『 『 『 『 『 『 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本As shown in the figure: where the balance arm 10 is the first, 3 cases of the lion 18 and the support surface (not shown in the figure) are flat: the pair is moved and the j 12 series is designed to be relatively vertical in the position to the =f-branch space The second support arm cover 35, the first control, and the second spring 24 are disposed between the second U 28 and the second control. The distal end 43 of the second bullet* 24 is connected at the 35th. The inner empty fft link 38, the sliding connector 32 and the coupling member are further rotated in the range of degrees 1 and have an inner standing at 65 and the first spring 26 is disposed inside the upper arm cover 55 2^5^ Control arm, end f connection (four) arm 52, * end 51 connected to two bombs * 苐 a support arm cover 35 and upper arm cover? 55.

Every 3, it can also protect the operator from being the first branch and the first one; seeing the window opening connector and the upper arm connecting member 20, and the younger one supporting arm 12; !16 郷 connecting cap 59 is beautiful in appearance and shape . In addition, a support arm 14 and a second support f 12 are: improved to be able to fasten the arm of the f-support arm 12 and the intermediate connecting member 16, and the lunar surface is provided with a protrusion, and an f f piece can be connected. One or both side walls of the female housing 41 41 are provided with protrusions, which can be aligned, and the small holes 78 in the wall of the housing arm cover 55 are connected to the first support arm cover 35 and the upper second spring 24 and the first Impeachment? R Zhanwu 5 has a younger support arm 14, and the flat force of the supported object 22 at a wide range of angles can support the resistance of the arm ίο. In the embodiment corresponding to the tfl, the balance has a correction. The resistance is supported by the non-linear change of the force + moment'. Due to the balance arm 10 of the second support arm 12 or the second support arm 12, when the first position is moved to another equilibrium position, the support arm 14 is from a balance position to the second spring 24, the first magazine 26 m The power is minimal, even through the 66A, 66B, 66C, the balance arms 1 , ^ the connection points 42A, 42B, 42C, 22, and in some embodiments support different weights of the support _ medium thousand balance arm 10 Use the second support arm cover 1307753 f body 55 to fix the electric_and the like, and avoid seeing the exposed =!
