The present invention relates to a pivotal device for a monitor and includes a connection member fixed on the monitor and a link which is pivotably connected between the connection member and the base so that the monitor can be pivoted and secured at desired angles.
A conventional pivotal device for monitors is connected between a base and the monitor which can be pivoted about a bolt of the pivotal device and secured at a desired angle. However, the sizes of monitors are made much larger than before so that the weight of the monitors is difficult to be supported by the friction of the pivotal device. Therefore, the large size monitor can only be pivoted at limited angles which are not satisfied by the users.
The present invention intends to provide a pivotal device for a monitor and the center of weight of the monitor is located in the area compassed by the link and the connection member of the pivotal device, so that the monitor can be well supported at desired angles.
The present invention relates to a pivotal device for monitors and the device comprises a connection member fixed to a rear side of the monitor and the connection member is pivotably connected on a base. A link has a first end pivotably connected to the connection member and a second end of the link is pivotably connected to two lugs on the base. A distance is defined between the connection member and the lugs. The link can be pivoted and moved axially relative to the lugs so as to support the monitor at desired angles.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to FIGS. 1 to 4, the pivotal device for monitors 10 of the present invention comprises a connection member 20 which is received in a recessed area 11 in a rear side of the monitor 10 and the connection member 20 includes two legs 21 which are pivotably connected to two lugs 41 on the base 40 by a bolt 23 which is connected with a nut.
A link 30 has a hole 31 defined in the first end thereof and the first end of the link 30 is pivotably connected to the two lugs 22 extending from the connection member 20 by another bolt 23 cooperated with a nut. A second end of the link 30 has an axial slot 32 define therethrough and the second end of the link 30 is pivotably connected to a lug 42 and a restriction lug 60 by an adjustment bolt 50 and a nut. The lug 42 is split from the bas 40 and the restriction lug 60 which is fixed on the base 40 by a bolt. A distance is defined between the connection member 20 and the lug 42 and the restriction lug 60. The adjustment bolt 50 extends through the slot 32 and the lug 42 and the restriction lug 60. An elastic assembly is sandwiched between the link 30 and the lug 42 and the restriction lug 60 so as to provide proper biasing force to prevent the adjustment bolt 50 from spinning and to generate friction force. The elastic assembly includes a plurality of flexible washers 70 and 80. The flexible washers 70 can be replaced with oil bearings or linings and the washers 80 can be bowl-shaped or flat washers so as to generate a force to prevent the adjustment bolt 50 from spinning.
The adjustment bolt 50 includes a polygonal head 51 and the restriction lug 60 includes a restriction arrangement which is a polygonal hole 61 with which the polygonal head 51 of the adjustment bolt 50 is engaged. By the engagement of the polygonal hole 61 and the polygonal head 51, the adjustment bolt 50 does not spin.
As shown in
The pivotal device provides a large support area composed of the restriction lug 60, the lug 42 and the lugs 41 so that the center of weight of the monitor 10 falls in the area so as to be well supported. The arm of force “L” between the lugs 41 and the center of weight of the monitor 10 has a certain length so that the torque to prevent the monitor 10 from falling backward is sufficient. The link 30 can be easily adjusted and fixed in position by operation of the adjustment bolt 50 to support the inclination of the monitor 10.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
