The present invention relates to a support assembly of a monitor, and more particularly to a monitor support assembly capable of rotatably supporting a monitor of an ultrasonic diagnostic apparatus.

In general, an ultrasonic diagnostic apparatus is a device that emits ultrasonic waves to a subject using a probe and generates an image by using the reflected signal. Especially, an ultrasonic diagnostic apparatus detects and detects foreign substances in living organisms. It is useful for medical purposes such as measurement, observation of tumor and observation of fetus.

1 is a front view showing a conventional ultrasonic diagnostic apparatus. As shown, the conventional ultrasonic diagnostic apparatus 1 includes various types of probes 11 for radiating ultrasonic waves to a subject and receiving ultrasonic echoes from the subject, and receiving them through the probe 11. A main body 10 equipped with an electronic circuit for processing the echo signal, a function selection keyboard 12 and the like, and an image display device 20 for realizing the echo signal processed by the electronic circuit or the like as an image. . In recent years, LCD monitors are generally employed as image display devices, and the ease of positioning of the LCD monitor 20 has emerged as one of the important qualities of the ultrasonic diagnostic apparatus.

2 is a perspective view of a conventional monitor support assembly. As shown, the stand 30 for interconnecting the main body 10 and the monitor 20 of the ultrasonic diagnostic apparatus has a base 31 installed on the main body 10 of the diagnostic apparatus, and upper and lower ends thereof, respectively. It is rotatably coupled to the monitor 20 and the base 31 via the monitor hinge 32 and the base hinge 33.

On both sides of the stand 30, a pair of link members 34 for transmitting the rotational movement of the stand 30 relative to the base 31 to the rotational movement of the monitor 20 are installed side by side. The link member 34 serves to rotate the stand 30 coupled to the base 31 so that the monitor 20 can rotate at a predetermined angle.

The base hinge 33 is composed of a first base hinge portion 33a and a second base hinge portion 33b, and the stand 30 rotates downward toward the base 31 side in the first base hinge portion 33a. The torsion spring 33c is provided to cancel the torque generated by the load of the monitor 20 by applying the elastic force in the opposite direction to the.

The first base hinge portion 33a and the monitor hinge 32 are coupled to each other while maintaining a predetermined frictional force with the inner hinge shaft (not shown) of the hinge shaft insertion hole, which is also generated by the load of the monitor 20. It is designed to withstand torque.

However, the conventional monitor support assembly configured as described above has the following problems.

When the user grabs the monitor 20 and applies pressure upward or downward, the inclination angle of the stand 30 relative to the base 31 is adjusted while the stand 30 rotates about the base hinge 33. At this time, the inclination angle θ of the monitor 20 is also automatically adjusted by the link member 34. That is, when the inclination angle of the stand 30 with respect to the base 31 is adjusted, the inclination angle of the monitor 20 with respect to the stand 30 is also automatically adjusted to maintain the current state.

Of course, if the top or bottom of the monitor 20 is pushed or pulled backwards or forwards, it is also possible to adjust only the inclination angle of the monitor 20 with respect to the stand 30 while the monitor 20 rotates about the monitor hinge 32. Do.

By the way, since the conventional monitor support assembly 1 depends on the friction force of the torsion spring 33c and the hinge shaft by the weight of the monitor 20, the inclination angle θ of the stand 30 with respect to the base 31. When the predetermined angle range is exceeded, the operating force is applied to the torque required more than the required torque required for adjusting the angle of the monitor 20, and thus there is a problem that the inclination angle adjustment cannot be made smoothly.

More specifically, as shown in FIG. 3, the required torque Tn required to support the monitor 20 according to the change of the inclination angle θ is converted into a curved trajectory. However, according to the change of the inclination angle θ, the torque Ts that can be implemented by the torsion spring 33c is changed while forming a linear trajectory, and the total torque Ta that can be realized by the frictional force of the torsion spring 33c and the hinge shaft is also changed. It is changed while forming a linear trajectory. This is because the torque Ts of the torsion spring 33a is proportional to the spring constant and the torsion angle, and the frictional force is constant regardless of the inclination angle.

Therefore, when the inclination angle is smaller than the predetermined range or larger than the predetermined range, since the difference between the required torque (Tn) and the actual implementation torque (Ta) is large, the magnitude of the change in the operating force due to the change of the inclination angle is severe, and accordingly flexible operation There is a problem that is not made.

The present invention is to solve the problems of the prior art, an object of the present invention, even if the inclination angle is changed to less than a predetermined range or more than a predetermined range can minimize the deviation of the operating force monitor support assembly of the ultrasonic diagnostic apparatus is made flexible operation To provide.

4 to 6 are a perspective view, an exploded perspective view and a side cross-sectional view showing a monitor support assembly of the ultrasonic diagnostic apparatus according to the preferred embodiment of the present invention, respectively.

As shown therein, the monitor support assembly according to the preferred embodiment of the present invention includes a base portion 100 and a base portion rotatably coupled to one side of the main body of the ultrasonic diagnostic apparatus (see FIG. 1). A pair of arms 200 having one end hinged to each other so as to be rotatable up and down with respect to each other, and the other end of the pair of arms 200 are connected so that the pair of arms 200 interlock with each other and the monitor (not shown). Stretching member 400 provided between the monitor support portion 300, and a pair of arms (200) for supporting) to prevent rotation of the arm (200) against the moment caused by the load of the monitor through the elastic force ), An elastic force adjusting means 500 for adjusting the elastic force by adjusting the length of the elastic member 400, and friction means for correcting the deviation of the moment due to the load of the monitor and the elastic force of the elastic member 400 ( 600).

The base part 100 is rotated to the fixing plate 110 by a fixing plate 110 mounted on one side of the upper surface of the main body of the ultrasonic diagnostic apparatus through a mounting means such as a screw, and a rotating shaft 111 provided at the center of the fixing plate 110. It includes a first connection member 120 that is possibly coupled. A pair of arms 200 are hinged to one side of the first connecting member 120 so as to be pivotable in a vertical direction. Such hinge coupling sequentially one side of the first connecting member 120 and one end of each arm 200. The first and second hinge shafts 121 and 122 penetrate through each other.

The pair of arms 200 has a substantially rectangular shape extending to a predetermined length, and each arm 200 is formed in a length and a shape corresponding to each other. ) And the installation shaft 210 for easily connecting each arm 200 is coupled.

The monitor support part 300 is formed by a second connecting member 310 for connecting the other ends of the pair of arms 200 to be interlocked with each other, and a second rotating shaft 311 provided in the second connecting member 310. And a first bracket 320 rotatably coupled to the second connection member 310 in a horizontal direction, and a second bracket 330 rotatably coupled to the first bracket 320 in a vertical direction and to which the monitor is mounted. .

The second connecting member 310 of the arm 200 through the third and fourth hinge shafts 312 and 313 are sequentially coupled through the other end of the arm 200 and the second connecting member 310. The other end is connected. That is, both ends of the pair of arms 200 are connected to each other through the first and second connection members 120 and 310. Accordingly, when the pair of arms 200 rotates, the arms 200 always rotate while maintaining the same extending direction. Therefore, the distance between the pair of arms 200 is variable according to the rotation angle of the arm 200.

The second bracket 330 is coupled to one side of the rear surface of the monitor by mounting means such as screws to support the monitor, and one side is hinged to the first bracket 320. The hinge coupling of the second bracket 320 is made by the monitor support shaft 340 which is sequentially penetrated through one side of the first and second brackets 320 and 330. Here, the monitor support shaft 321 is provided with a rotation control member 340 to control the rotation by the moment of the load of the monitor on which the second bracket 320 is mounted. In the rotation control member 340, the monitor support shaft 321 is inserted into the center thereof, and both ends thereof are fixed to the first and second brackets 320 and 330, respectively, so that the monitor is rotated by the load on the second bracket 330. It is a torsion coil spring which transmits an elastic force in a direction opposite to the direction and intermittently prevents the second bracket 330 including the monitor from being rotated by a moment caused by the load of the monitor.

The elastic member 400 prevents the arm 200 from being rotated by the moment due to the load of the monitor, and once the mounting shaft 210 is coupled to any one arm 200 of the pair of arms 200. The other end is fixed and fixed to the mounting shaft 210 coupled to the other arm 200 is fixed. Since the elastic member 400 is connected in a diagonal direction between the pair of arms 200, the elastic force also acts in the diagonal direction. In this way, there is a component force acting in the direction of the moment due to the rotation of the arm 200 among the components of the elastic force acting in the diagonal direction, and the friction force between the component force and the friction means 600 is the load of the arm 200. Optimum response to the moment due to In the present exemplary embodiment, two tension springs are arranged in series in the longitudinal direction of the arm 200 as the stretchable member 400. However, the present invention is not limited thereto. There may be various modifications in the material, number, and arrangement of the 400, such as serial arrangement of the arms in the longitudinal direction or parallel arrangement of the arms in the width direction. In addition, the elastic member 400 is connected to the arm 200 by hanging on the installation shaft 210, the distance between the arm 200 is variable as the pair of arms 200 is rotated, and accordingly each arm ( Since the expansion and contraction member 400 fixed to both ends is rotated and stretched, the connection between the expansion member 400 and the arm 200 is to prevent the noise is generated. In addition, the installation shaft 210 is coupled to the bearing or bushing freely rotated by the installation shaft 210 as the rotating shaft so that the end of the elastic member 400 can be easily hooked.

The elastic force adjusting means 500 is for adjusting the elastic force of the elastic member 400 by adjusting the length of the elastic member 400, and a support block fixed to one arm 200 of the pair of arms 200 ( 510 and one side of the installation shaft 210 is coupled to the transport block 520 and the support block 400 is connected to one end of the elastic member 400 is supported by the forward and backward moving block 520 straight line Moving rod includes a movable rod 530 for adjusting the length of the elastic member 400 connected thereto. In the present embodiment, it is shown that by using one elastic force adjusting means 500 to adjust the length of one elastic member 400 connected to the elastic force adjusting means 500, but is not limited to this of the elastic member 400 According to the number of installation or arrangement (serial or parallel arrangement) and the like provided with a plurality of elastic force adjusting means 500 can be modified to adjust the length of the plurality of elastic members 400, respectively.

The movable rod 530 is screwed to one side of the support block 510 in a threaded rod shape along the periphery of the surface, and one end of the movable rod 530 is rotatably supported on one side of the transfer block 520. Since the movable rod 530 is supported by the support block 510 in the rotation to move forward and backward along the thread, the movable block 520 is to move linearly.

The friction means 600 includes a dish washer 610, the center of which is inserted into and coupled to at least one of the first to fourth hinge shafts 121, 122, 312, and 313, and the dish washer 610 as it is tightened. It pressurizes to the arm 200 side and includes a pressing nut 620 to bring the arm 200 and the dish washer 610 in close contact. The friction means 600 corrects the deviation between the moment due to the load of the monitor rotated to 0 ° or less and the elastic force of the elastic member 400 through the pressing force of the pressure nut 620 and the friction force of the dish washer 610. .

Hereinafter will be described the operation and effect of the monitor support assembly of the ultrasonic diagnostic apparatus according to the present invention configured as described above.

7 is a side view schematically showing the operation of the ultrasonic diagnostic apparatus according to an embodiment of the present invention.

As shown in the drawing, when the user applies force to the monitor to rotate the arm 200 downward, each arm 200 rotates about the first and second hinge shafts 121 and 122, so that the arm ( The spacing between the 200 becomes narrow and the angle between the arm 200 and the elastic member 400 becomes smaller. Accordingly, the elastic member 400 rotates and at the same time as the length is extended, the elastic force is increased, the force is added to the elastic force and the friction force of the friction means 600 due to the load of the monitor and the arm 200 according to the inclination angle Follow the trajectory corresponding to the overall trajectory of the moment.

FIG. 8 is a graph schematically showing the relationship between the action force of the elastic member and the friction means and the moment due to the load of the monitor and the arm employed in the monitor support assembly of the ultrasonic diagnostic apparatus according to the preferred embodiment of the present invention.

As shown in the figure, the moment Tn due to the load of the monitor and the arm shows the largest nonlinear trajectory at the inclination angle of 0 °, and the force Ta 'which is the addition of the elastic force of the elastic member and the frictional force of the friction means is also included in the inclination angle. It can be seen that the trajectory of the moment Tn due to the load is followed to draw a nonlinear trajectory. The reason is that at the inclination angle of 0 ° or more, the elastic force of the elastic member and the inclination angle increase as the inclination angle becomes smaller, and the friction force of the constant friction means is added to follow the trajectory of the moment Tn due to the load. As in the inclination angle of 0 ° or more, the elastic force of the elastic member, which becomes larger as the inclination angle becomes smaller, is canceled by the friction force of the friction means to follow the trajectory of the moment Tn due to the load. In more detail, the elastic member gradually increases its length as the inclination angle of the arm decreases, and the moment force (Tn) due to the load of the monitor and the arm becomes close to 0 ° from the inclination angle of the arm from 0 ° or more. As it gradually increases, it corresponds to the elastic force of the elastic member, but when the inclination angle becomes smaller than 0 °, the moment Tn due to the load of the monitor and the arm gradually decreases. Accordingly, the moment Tn due to the elastic force and the weight of the elastic member causes a deviation at an inclination angle of 0 ° or less, and the deviation is corrected using the friction force of the friction means. In other words, the frictional force of the friction means is added to the elastic force of the elastic member at an inclination angle of 0 ° or more, and the frictional force of the friction means is offset from the elastic force of the elastic member at an inclination angle of 0 ° or less so that the frictional force of the friction means is added to the elastic force of the elastic member. The deviation between Ta 'and the moment Tn due to the load is minimized. Accordingly, when rotating an arm having an inclination angle of 0 ° or more to 0 ° or less, a force greater than the elastic force of the elastic member and the friction force of the friction means must be transmitted, but an arm having an angle of inclination of 0 ° or less should be 0 ° or more. When rotating, it is only necessary to transfer a greater force to the elastic force of the elastic member than the friction force of the friction means.

The present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims.

As described in detail above, the monitor support assembly of the ultrasonic diagnostic apparatus according to the present invention provides the following effects.

First, even the inclination angle of less than 0 ° can minimize the deviation of the operating force is a flexible operation is made.

Second, even if the length of the arm is increased, there is no restriction on the length of the arm because it is necessary to increase the number of elastic members.

Third, the elastic force of the elastic member can be arbitrarily adjusted so that the force required to rotate the monitor can be adjusted to the user.

Fourth, lowering the arm with an angle of inclination of 0 ° or less to 0 ° requires a relatively large force, but raises an arm with a relatively small force when raising an arm with an angle of inclination of 0 ° or less to 0 ° or more. Can be rotated to improve the user's convenience.
