BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a torque hinge for use in a torque hinge mechanism for an electronic device, which is used for opening and closing a portable computer or the like. The department opens the set angle when it is used. In this case, the priority is claimed in the patent application No. 2004-160907, filed on May 31, 2004, and the content of the application is hereby incorporated herein.先前 # [Prior Art] The torque hinge is used not only for personal computers, but also for various components such as covers and doors that rotate the shaft to open and close. Also, the torque hinge, Xi = has proposed various structures, which are used according to the purpose and price. There is a torque hinge with a simple structure and a low price, as shown in FIG. 4, which is a shaft member, a shaft member 52, a mounting member 53, and a screw or screw. It is configured (for example, refer to Japanese Laid-Open Patent Publication No. 2 (9)).

The hour bushing spring member 51 is composed of a bush spring portion MA and first and second twin plate portions 51B and 51C. The sleeve spring portion 51A bends the metal piece of the elastic body into a left-right symmetry, and bends into a left-right symmetry and a shape = a coaxial structure #52 insertion. The i-th and second elastic plate-like portions 5jC extend from the boss spring portions 51A substantially in parallel with each other. The shaft-time member 51 is inserted into the insertion hole h by the shaft member 52, and is attached to the mounting structure #53 by clamping the first and second elastic plate portions 5iB, 5ic by the member 54. The magnitude of the rotational torque of 1295711 between the bushing spring 51A and the shaft member is adjusted according to the strength of the clamping member 54 for clamping the first and second elastic plate portions 51B, 51C. 】

The conventional torque is compared with the chain. As described above, the metal piece is bent to be bilaterally symmetrical, and the second and second elastic plate-like portions are fixed by the fixing member 54 such as a screw or a bolt, and the 51C is attached to the mounting structure. The fixing member Μ functions to adjust and mount the torque. The second elastic plate-like portions 51B and 51C extend substantially straight from the sleeve spring portion symmetrical. However, such conventional torque hinges have the following problems. In the conventional torque hinge described above, if the mounting manner is completely bilaterally symmetrical, the left and right rotational torques generated are substantially the same, not 35. Actually, the mounting member 53 is attached to the mounting member 53 by using the fixing member 54 (disposed on the wall, the electronic machine number). Since the main body portion or the like is on the object side, the contact portion of the attachment member 53 and the first elastic plate-like portion abuts the contact of the (four) 54A of the elastic plate-shaped portion W (the screw or the bolt). Part. Therefore, the magnitude of the biasing force applied to the elastic plates 51B and 51C of the younger brothers 1, f 2 becomes unbalanced, and the rotational torque applied to the plate-like portions is large, and the rotational torque on the opposite side is increased. The torque is smaller. That is, the magnitude of the rotational torque acting to the left differs greatly from the magnitude of the rotational torque acting to the right. The purpose of the invention is to solve the above problem by providing a means of providing a torque hinge mechanism in which the difference between the leftward rotational torque and the rightward rotational torque is reduced by J or substantially equal. The present invention provides a torque hinge having a spring member bent into a sleeve spring portion and a second elastic plate portion, and the sleeve spring portion has an insertion hole for inserting the shaft member. Torque, this second, a rotation extension between the shaft members. The elastic plate-like portion of the penetrating floor is connected to the first and second elastic plate portions from the sleeve spring portion via the spacer fixing member. , · Raise: 'Used to fix the spring member to the mounting member, and adjust the size of the moment between the spring and the shaft member and the shaft member; and the rotation of the sentence 4, and the帛2 Elastic plate-shaped portion of the other weight: An = 〗, the second elastic plate-like portion is sandwiched between the rotating torque equalizing members (10) ^ member; the Dib 2 elastic plate-like portion, through the rotating torque The specialized component is clamped by the (four) component and (d) is mounted to the component. Preferably, the torque equalizing member has a front end surface 'the front end surface extending to the same position as the opposite front side of the mounting member, or extending to correspond to the mounting member. The front end face is more 2 sin near the position of the sleeve spring. In the torque hinge of the present invention, it is preferable that the rotational torque equalizing member 3 is constituted by a plate magazine. According to the present invention, it is possible to provide a torque hinge capable of reducing the difference in rotational torque between the left and right directions by a simple means. X, if the rotating torque 4 is equalized, the plate spring is used, and the % fixed member is not easily loosened by vibration, etc., so that a more reliable torque hinge can be provided. [Embodiment] Embodiment 1 A torque hinge 100 according to a third embodiment of the present invention will be described with reference to Figs. 1 and 2 . 1 is a cross-sectional view of a torque hinge 100, and FIG. 2 is a top view of a torque hinge 100. 1295711 The torque hinge 100 has a sheet metal bending member 1 which is composed of a viscoelastic material such as carbon tool steel. The elastic member 丨 is composed of a sleeve elastic portion 1A, a second elastic portion iB, lc, and an abutting portion ι〇, ιε. The two sleeves "weighing" are used to generate a rotary twist between the shaft member 2 and the two gap extensions::, C, respectively, from the sleeve spring portion 1A through the "quote", respectively, from a pair of elastic plates Department 1B lc

The extension 'and the mutual force generated by the external force against each other in the C portion 1D, 1E as the elastic plate portion called the front end portion of the c. The abutting bushing spring portion 1A is symmetrically bent to form an insertion hole Hi. The section is rounded back /

Insert the hole H1. In the two (four) ^ bushing spring portions 1A d, the two elastic plate portions 1B, 1C are respectively formed with two screws: the through hole is inserted into the screw or the bolt 4, and the second side is placed on the opposite side, or the bolt 4 is The yellow member 1 is attached to the female cow 3. In the present invention, at the time of mounting, Π;: ΓΓ-shaped...heavily equal-equal 等m is characterized in that it is clamped by the screw or screw 4 and the nut 5 through the rotational torque uniform member 6. The rotational torque equalizing member 6, for example, a metal plate composed of a genus material or (four) ml two identical yellow: the member 1 is substantially the same. The rotational torque equalizing member 6::: = ^ is located at the position of the sleeve of the rotating torque equalizing member 6 to extend to the position of the front end of the mounting member 3 or the ::, the end surface 3a, or to the magazine of the sleeve It is the position of the iA side than the previous (four). In addition, the 'rotational torque equals 9 1295711 4 匕 I: # 6p The degree of inclination is roughly (four) the end of the sac, the degree of inclination of the f is the abutment of the abutting portion 1D I and 1, in the elastic plate portion 1B, 1C Tight (4) constitutes a fixed member. In the first embodiment, the 'screw or thread check 4 and the nut 5 nails: and the 'shown in Fig. 2' are in a state in which the respective members are combined, and the screw is screwed against the nut 5, and the head of the screw or bolt 4 is screwed 4A. Needle] = the lower side of the dust rotating torque equalizing member 6. - Generally speaking, the area under the king 4 is small, not necessarily flat, so when the rotating torque equalization member 6 does not exist, the snail (4) screw inspection 4 head field 4α^ ugly::::Γ The tightness (4) of the elastic portion 1A is smaller than that of the mounting member 3: Γ: 1Α tight. Here, the surface of the rotating torque equalizing member 6 extends to the same or more than the front end of the mounting member 3 Fully elastic: the position on the side of the portion 1A' and the rotational torque equalizing member 6 has a rigidity of » so that the upper portion of the pattern is applied downward by the rotating torque equalizing member 6 (screw or Insertion of the bolt 4: When the pressure is tight, the pressing force is substantially equal to the pressing force applied to the upper side of the mounting member 3 to the lower side of the sleeve (the insertion direction of the screw or the bolt 4). Therefore, the spring member i-shaped plate portion! B, 1C is sandwiched between the mounting member 3 and the rotational torque using the rotational torque equalizing member 6, and the members are clamped using the fixing member 4, and the pumping member can be used. The sleeve ear iA exerts a substantially equal clamping force. In this way, the sleeve elastic portion 1A and the shaft structure The value of the rotational torque generated between the two is approximately equal. 9 1295711 Further, the width of the rotational torque equalizing member 6, that is, the width in the direction of the paper surface is preferably greater than or substantially equal to the spring member in the same direction.

A torque key according to a second embodiment of the present invention will be described with reference to FIG.

20 years old. Fig. 3' shows a section of the torque hinge 2'', characterized in that the sleeve elastic portion 11A of the magazine member has a regular hexagon shape, and the rotational torque equalizing member 16 is an arc-shaped leaf spring. The same symbols as used in the ® 1 and Figure 2 indicate components having the same name. The y-sleeve H-portion 11A has approximately six sides 12 of equal length. Each of the sides 12 is formed in an arc shape slightly protruding toward the insertion hole H2 side of the shaft member 2, and the shaft member 2 is clamped at six / (vertices of the sides 12). With such a configuration, a stable and effective rotational torque can be generated between the boss spring portion UA and the shaft member 2. The suspected torque equalization structure j6 is a plate magazine that is bent into an arc shape, and a hole (not shown) for inserting a screw or a bolt 14 is formed in the bowl portion. Rotational Torque The shape of the arc of the second-class member 16 is bilaterally symmetrical in the drawing. The end 16a# of the rotary torque reducing member 16 is on one side of the sleeve spring portion ,, and the reference 16c is close to the abutting portions 11D, 11E of the spring member u. In the same manner, one end of the rotational torque equalizing member 16 is closer to the sleeve spring portion "a side than the corresponding end 3a of the mounting member 3. One is a protrusion formed by stamping in advance. The rotating torque is equal to 8 11 1295711. The structural member 16 is a leaf spring composed of a common spring material. The elasticity is large, and the elastic force is concentrated on the 6a and the other end (6), so the thickness of the plate can be made more than that of the user (4) chain H). thin. Therefore, if the rotational torque equalizing member utilizes this configuration, it can be made thinner than the plate thickness of the spring member u. And twist 16

As shown in FIG. 3, when the screw or the screw is rotated in the state of the combination of the members to be screwed to the nut 15 and advanced, the lower torque of the head of the screw or bolt 14 is equalized by the torque equalization member. 16. The tight pressure of the end is applied to the boss portion 11A. Therefore, the spring member has an elastic plate shape. The interval between the P 11B XI 1 ic becomes narrow, and the action of the sleeve elastic portion 11 a causes the insertion force of the hole H2 to become narrow. Therefore, the sleeve spring portion "A clamping shaft member 2' generates a rotational torque between the sleeve spring portion 11A and the shaft member 2. By adjusting the degree of screwing of the screw or bolt 14 to the nut 15, the desired rotational torque can be obtained. In the second embodiment, the tension member which is continuously applied to the screw or the bolt 14 and the nut 15 due to the rotation equalization member 6 is not easily loosened, and the seed can maintain the initial rotational torque characteristic. High reliability torque hinge. Further, the sleeve spring portion 11A of the torque hinge 200 is a regular hexagon, but may be an equilateral triangle, a regular quadrangle, a regular pentagon or the like. Further, the width of the rotational torque equalizing member 16 is not necessarily limited to the case where it is equal to the width width w of the boss portion 丨丨A of the bomb member 11, and is larger or smaller than the width w of the boss portion 11A.
