1 is a perspective view of a tilting device according to an embodiment of the present invention, Figure 2 is a schematic diagram of a tilting device according to an embodiment of the present invention, Figure 3 is a method of offsetting the gravity moment according to an embodiment of the present invention A diagram for explaining. 1 to 3, the tilting apparatus 10, the support member 12, the tilt member 14, the guide frame 15, the first elastic member 16, the second elastic member 17, and the hinge The shaft 18, the coupler 19, the weight 20, the first pulley 22, the second pulley 24, the motive gear 26, the third pulley 28 and the rack 30 are shown. It is.

The tilting device 10 of the present embodiment includes a tilting member 14 capable of being detachable from the supporting member 12 and the weight body 20 and hinged to the supporting member 12 about the hinge shaft 18. The elastic force is applied to the first elastic member 16 for elastically supporting the tilt member 14 and the gravity moment of the weight body 20 so as to cancel the gravity moment of the weight body 20, and the adjustment of the elastic force is performed. With the second elastic member 17 as possible as a component, the weight body 20 is supported to be tiltable and the vertical angle of the weight body 20 of various weights can be adjusted without replacing the elastic member.

As the weight 20 used in the tilting apparatus 10 of the present embodiment, a CRT TV, a monitor, or a flat panel display may be used. Of course, not only the display but also various weights 20 that require vertical angle adjustment may be used.

The support member 12 is a member for fixing the tilting device 10 of the present embodiment to a predetermined position, and the tilt member 14 is coupled to a weight body 20 such as a display to rotate the tilt member 14. The vertical rotation angle of the sieve 20 can be adjusted. The tilt member 14 allows the weight body 20 such as a display to be detachable so as to detach the weight body 20 of various specifications.

The tilt member 14 is hinged around the hinge shaft 18 to the support member 12 to adjust the vertical rotation angle of the weight body 20 such as a display. The tilt member 14 may include a guide frame 15 corresponding to the size of the weight body 20 such as a display, and the tilt member 14 including the guide frame 15 may be a large weight body 20. ) Can be supported stably.

When the weight body 20 is attached to the tilt member 14, the first elastic member 16 may elastically support the tilt member 14 to offset the gravity moment of the weight body 20. In addition, the second elastic member 17 may apply an elastic force in a direction that resists the gravitational moment of the weight body 20, and may control the elastic force to correspond to the weight body 20 having various weights. That is, when the weight of the weight body 20 detachable from the tilt member 14 changes, the elastic force must be changed to properly offset the gravity moment, and the elastic member must be replaced or the elastic force can be adjusted to change the elastic force. do. However, replacing the elastic member may be a problem in standardizing the tilting device 10. Therefore, by adjusting the elastic force according to the weight of the weight body 20 attached to the tilt member 14 can be manufactured by standardizing the tilting device 10 without replacing the elastic member.

Referring to FIG. 3, the gravity moment M is a moment applied to the hinge shaft 18 due to the weight W of the weight body 20, and the weight W of the weight body 20 is applied in the direction of the earth's gravity. The moment is applied to the value (M = W · R) obtained by multiplying the force by the distance R from the hinge axis 18 to the center of gravity of the weight body 20. (Here, the self weight of the tilting device 10 is ignored in explaining the concept of the invention.)

In the case of automatically tilting the weight body 20 such as a display, when the weight body 20 is rotated in response to the moment with respect to the total weight of the weight body 20, a large capacity power source is required and accordingly, the space is limited. However, costs can be increased. The elastic member applies an elastic force to the tilt member 14 in advance in the direction of resisting the gravity moment of the weight body 20 (for example, in the direction of the arrow shown on the left side of FIG. 3) to the gravity of the weight body 20. To cancel the moment by allowing the tilting of the weight body 20 with a small capacity power source.

 In this embodiment, the tilt member 14 is elastically supported in advance so as to offset the gravity moment of the weight body 20 with the first elastic member 16, and the elastic force with the second elastic member 17 for the rest. It may be adjusted to correspond to the change in the weight body 20. As such, by providing a plurality of elastic members, it is possible to finely adjust the elastic force to correspond to the weight body 20 of various weights. For example, when attempting to standardize the tilting device 10 for the weight body 20 in the range of 20 kg to 40 kg, a distance from the hinge axis 18 to the center of gravity of the weight body 20 is 10 cm. A gravity moment of 200 kg · cm occurs with respect to the weight body 20 having a weight of 20 kg, and a gravity moment of 400 kg · cm with respect to the weight body 20 having a maximum weight of 40 kg. Therefore, in order to effectively offset this and tilt the weight 20 with a small power source, about 200 kg · cm for the weight 20 of the minimum weight 20 kg and about 400 kg · cm for the weight 20 of the maximum weight 40 kg. Moment due to elastic force is required. If the first elastic member 16 offsets the gravity moment 200 kg · cm in advance, the elastic force of the second elastic member 17 is adjusted to apply the moment by the remaining elastic force of about 0 to 200 kg · cm to 20 kg. It is possible to standardize the tilting device 10 for the weight body 20 in the range of 40kg. That is, without applying the elastic force of the second elastic member 17 to the 20kg weight body 20, the second elastic member 17 to offset the remaining 100kgcm about the 30kg weight body 20 ). In addition, the 40kg weight body 20 is adjusted to offset the remaining 200kgcm. As such, by offsetting the predetermined gravity moment with the first elastic member 16 and adjusting the rest with the second elastic member 17, fine adjustment of the elastic force is possible without applying a large force, and thus the weight of various standards. It can correspond to a sieve.

The driving unit provides a driving force to tilt the tilting member 14 from which the weight body 20 is detached. As shown in FIG. 2, the driving unit is coupled to both ends of the supporting member 12. The pulley 22 and the second pulley 24, the motive gear 26 and the third pulley 28, which are coupled to the tilt member 14, one end is fixed to one end of the tilt member 14 and the first pulley 22 ), The rack 30 which is fixed to the other end of the tilt member 14 through the motive gear 26, the second pulley 24 and the third pulley 28 in order to be engaged with the motive gear 26, and It may include a motor (not shown) for providing a rotational force to the prime mover (26). The driving unit having such a configuration may adjust the vertical angle of the weight body 20 while the motive gear 26 rotates by the rotation of the motor and the rack 30 engaged with the motive gear 26 performs linear movement. have. That is, the prime move gear 26 rotates forward and reverse according to the forward and reverse rotation of the motor, and accordingly, the weight body 20 is hinged shaft 18 while the rack 30 meshed with the prime move gear 26 performs the linear movement of the forward and reverse directions. It is to rotate up and down about). However, the driving unit is not limited thereto, and various driving units may be used to provide a driving force to tilt the tilt member 14 within a range apparent to those skilled in the art.

Hereinafter, a method of operating the tilting device 10 of the present embodiment will be described with reference to FIG. 2.

When the motive gear 26 is rotated in the forward or reverse direction by the driving of the motor of the drive unit, the rack 30 engaged with the drive gear moves in the forward or reverse direction. That is, the rack 30 moves in the vertical direction by the forward and reverse rotation of the motor, so that one end or the other end of the rack 30 coupled to both ends of the tilt member 14 is both ends of the tilt member 14. Pull each of the tilt member 14 will be able to rotate in the vertical direction. For example, when the motor gear 26 is rotated in the right direction by a motor, one end of the rack 30 engaged with the tooth pulls one end of the tilt member 14, and thus the tilt member 14 is hinged. 18) it will rotate to the left. On the contrary, when the main gear 26 is rotated to the left by a motor, the other end of the rack 30 engaged with the tooth pulls the other end of the tilt member 14 so that the tilt member 14 is centered on the hinge shaft 18. It will rotate in the right direction.
