Detailed Description

Referring to fig. 1, 2 and 3, a display device according to a first embodiment of the invention includes a display stand 100 and a display 200.

As shown in fig. 1, 2 and 3, the display stand 100 is configured to be disposed on a plane S, so as to mount the display 200 on the plane S. The display stand 100 includes a stand 110, a base 120, a pivot 130, and a locking device 140.

As shown in fig. 1, 2 and 3, the stand 110 has a top end 112 and a bottom end 114. The bottom end 114 is disposed on the plane S, so that the stand 110 is disposed on the plane S. The stand 110 also has a sliding guide 116 extending from the top end 112 toward the bottom end 114. The sliding guide 116 may be partially disposed at a section of the stand 110 corresponding to the top end 112, and may extend from the top end 112 to the bottom end 114.

As shown in fig. 1, 2 and 3, the base 120 is slidably disposed on the stand 110 and is slidable to the top end 112. In one embodiment, the base 120 has a sliding portion 122 and two pivoting portions 124. The sliding portion 122 is slidably disposed on the sliding guide portion 116 of the stand 110, and two pivoting portions 124 extend from the sliding portion 122. The sliding guide 116 is a long slot, and a portion of the base 120, i.e., the sliding portion 122, is received in the long slot, such that the base 120 can slide toward the top end 112.

As shown in fig. 1 and 2, a positioning device 150 is disposed between the stand 110 and the base 120, so as to fix the base 120 at a specified position. The positioning device 150 may be a damper assembly, a ratchet assembly, or a dead bolt. In the drawings, a fixing bolt is taken as an example, and the fixing bolt is propped against or passes through the base 120 after passing through a fixing hole of the foot stool 110 from the outside of the foot stool 110 so as to fix the position of the base 120 on the foot stool 110, so that the base 120 cannot fall towards the bottom end 114. The fixing bolt is merely an illustration of the positioning device 150, and is not intended to limit the embodiment of the positioning device 150.

As shown in fig. 1, 2, 3 and 4, the pivot 130 has a mounting plate 132 and two pivot plates 134. The mounting plate 132 is used to be fixed to the back 220 of the display 200, and connects the pivot 130 to the display 200. The two pivoting plates 134 extend vertically to opposite sides of the mounting plate 132 and are pivoted to the pivoting portions 124 of the base 120. In addition, each pivot plate 134 has a limiting notch 134a. The display 200 has a front surface 210 and a back surface 220, the back surface 220 being secured to the mounting plate 132 of the hinge 130 to rotatably couple the display 200 to the base 120. The height of the display 200 relative to the plane S is changed by sliding the base 120 relative to the foot rest 110.

As shown in fig. 1, 2, 3 and 4, the locking device 140 is disposed on the base 120, and the locking device 140 has one or more movable stop pins 142 and an operating member 144. When the mounting plate 132 is perpendicular to the plane S, the stop pin 142 is normally inserted into the limiting notch 134a, so as to limit a rotation range of the pivot 130 relative to the base 120.

As shown in fig. 4, 5 and 6, the operating member 144 is configured to move on the base 120 to push the stop pin 142 out of the limiting notch 134a, so that the pivot 130 can rotate continuously to make the mounting plate 132 parallel to the plane S.

The number of the limiting notches 134a and the number of the blocking pins 142 are matched, that is, each limiting notch 134a is used for inserting one blocking pin 142. That is, only one pivot plate 134 of the pivot 130 and only one pivot 124 of the base 120 may be disposed. At this time, the pivot member 130 only provides a limiting notch 134a through one pivot plate 134, and in this case, only one stop pin 142 needs to be disposed on the locking device 140. In addition, the width of the limiting notch 134a may be greater than the width of the blocking pin 142, so that after the blocking pin 142 is embedded into the limiting notch 134a, the pivot 130 can still rotate by a small margin, and the pitching state of the display 200 is adjusted to match the line of sight of the user. Therefore, the blocking pin 142 is inserted into the limiting notch 134a, not for completely fixing the pivot 130 and the base 120, but for limiting the rotation range of the pivot 130 relative to the base 120.

As shown in fig. 6, when the base 120 is raised to the top 112, the rotation of the pivot 130 is not affected by the interference between the display 200 and the stand 110, so that the mounting plate 132 may be parallel to the plane S. At this time, the display 200 is also parallel to the plane S, the back surface 220 of the display 200 faces the plane S, and the bottom edge or the side edge of the display 200 faces the horizontal direction. In this case, the connection ports of the display 200 are located on the back 220, the bottom edge, or the side edges, which is relatively convenient for the user to plug in the electrical signal connectors.

Referring to fig. 1, 2, 4, 5 and 6, the operating member 144 of the first embodiment has a sliding block 144a and an elastic member 144b. The base 120 has one or more guide slots 126; the sliding block 144a further has one or more guiding posts 144c slidably disposed in the guiding slot 126, such that the sliding block 144a is slidably disposed in the base 120. Specifically, the sliding block 144a is disposed between two pivoting portions 124 of the base 120, and at least two guiding slots 126 are disposed on each pivoting portion 124, and an extending direction of the guiding slots 126 is perpendicular to the plane S; at least two guide posts 144c are disposed on opposite sides of the sliding block 144a, and are disposed in a guide slot 126, respectively, so as to limit the sliding block 144a to only move linearly relative to the base without rotating relatively. The resilient member 144b is normally compressed between the slider 144a and the base 120 to urge the slider 144a toward the tip 112. The stop pin 142 is disposed on the sliding block 144a, and the position of the stop pin 142 substantially corresponds to the pivot plate 134. When the mounting plate 132 is parallel to the plane S, the stop pin 142 can move toward the top end 112 to be inserted into the limiting notch 134a, and the elastic member 144b is used for maintaining the stop pin 142 to be inserted into the limiting notch 134a normally.

Referring to fig. 1, 2, 4, 5 and 6, the stand 110 further has a supporting column 118 disposed on the stand 110 and corresponding to the top end 112. The abutment post 118 extends toward the bottom end 114. When the base 120 is far away from the bottom end 114, the propping column 118 does not contact the sliding block 144a, so that the stop pin 142 is kept embedded in the limit notch 134a. At this time, the pivoting member 130 can only rotate between a limited angle with respect to the base 120, and the tilting state of the display 200 can be adjusted within a small angle range.

As shown in fig. 5, when the base 120 moves to the top end 112, the propping column 118 props against the sliding block 144a, so that the stop pin 142 is separated from the limit notch 134a. At this time, the locking device 140 releases the locking of the pivot 130, so that the pivot 130 can rotate continuously, and the display 200 is parallel to the plane S. As shown in fig. 4, when the mounting plate 132 is rotated again to be perpendicular to the plane S, and the base 120 is moved away from the top end 112 again, the abutment post 118 is separated from the sliding block 144a, so that the stop pin 142 is inserted into the limit notch 134a again to lock the pivot 130.

Referring to fig. 7, 8 and 9, a detent device 140 according to a second embodiment of the present invention is disclosed, and is applicable to a display stand 100 according to one or more embodiments of the present invention. In the second embodiment, the supporting column 118 of the stand 110 is omitted.

As shown in fig. 7, 8 and 9, the locking device 140 has at least one movable stop pin 142 and an operating member. The operating member further has at least one spring 144d and a sliding switch 144e. One end of the elastic piece 144d is disposed on the base 120, and the stop pin 142 is disposed on the other end of the elastic piece 144 d. Specifically, the elastic piece 144d is disposed outside the pivot portion 124, such that the stop pin 142 is aligned with the through hole 124a of the pivot portion 124, and a separation distance is maintained between the elastic piece 144d and the pivot portion 124. The base 120 further has an outer cover 128, and the sliding switch member 144e is coupled to the outer cover 128 and is movably disposed on the base 120.

As shown in fig. 9, 10, 11 and 12, the sliding switch piece 144e can move on the base 120 to a pressing position L and a releasing position R. The through hole 124a is disposed corresponding to the limit notch 134a; when the mounting plate 132 is perpendicular to the plane S, the through hole 124a overlaps the limiting notch 134a, so that the blocking pin 142 can be inserted into the limiting notch 134a after passing through the through hole 124 a.

As shown in fig. 7, 9 and 11, the sliding switch 144e has a positioning rod 145a and a pushing rod 145b, which passes through at least one through hole 128a of the outer cover 128. The supporting rod 145b is located between the elastic piece 144d and the pivot portion 124, and the positioning rod 145a is disposed corresponding to the stop pin 142.

As shown in fig. 9 and 10, when the sliding switch 144e is located at the pressing position L, the positioning rod 145a normally presses the elastic piece 144d toward the pivot portion 124, so that the stop pin 142 protrudes from the inner side of the pivot portion 124 through the through hole 124a and is normally inserted into the limiting notch 134a.

As shown in fig. 9 and 11, the positioning rod 145a has a guiding inclined surface 145c, one end of the blocking pin 142 is disposed corresponding to the elastic piece 144d, when the sliding switch piece 144e moves from the release position R toward the pressing position L, one end of the blocking pin 142 contacts the guiding inclined surface 145c, and the guiding elastic piece 144d deforms to enter between the positioning rod 145a and the pivot portion 124, so that the positioning rod 145a can press the elastic piece 144d toward the pivot portion 124, thereby driving the blocking pin 142 to insert into the limiting notch 134a through the through hole 124 a.

As shown in fig. 11 and 12, when the sliding switch 144e moves to the release position R, the positioning rod 145a is separated from the elastic piece 144d, and the pushing rod 145b moves between the pivot portion 124 and the elastic piece 144d toward the stop pin 142, and pushes the elastic piece 144d away from the pivot portion 124, so that the stop pin 142 is separated from the limiting notch 134a.

Referring to fig. 13 and 14, a detent device 140 according to a third embodiment of the present invention is disclosed, and the display bracket 100 according to one or more embodiments of the present invention is applicable. In the third embodiment, the supporting column 118 of the stand 110 is omitted as well.

As shown in fig. 13 and 14, the locking device 140 has at least one movable stop pin 142 and an operating member 144. The operating member 144 is a telescopic device and is disposed on the base 120. The stopper pin 142 is provided to the telescopic device. The telescopic device is used for driving the stop pin 142 to stretch and retract, so that the stop pin 142 is embedded into the limit notch 134a through hole 124a of the pivoting portion 124; alternatively, the telescopic device may drive the stop pin 142 to disengage from the limit notch 134a. The retractable device is commonly used in writing instruments, and is a mechanism for retracting a pen core by pressing. As in the second embodiment, the through hole 124a is configured corresponding to the limit notch 134a; when the mounting plate 132 is perpendicular to the plane S, the through hole 124a overlaps the limiting notch 134a, so that the blocking pin 142 can be inserted into the limiting notch 134a after passing through the through hole 124 a.

As shown in fig. 13 and 14, in one embodiment, the telescopic device (i.e., the operating member 144) further includes a rotating disc 146a, a stop pin disc 146b, a press button 146c, and a compression spring 146d. The rotating disc 146a is pivoted to the pivoting portion 124 of the base 120, and the blocking pin disc 146b is disposed between the rotating disc 146a and the pivoting portion 124, so as to be driven by the rotating disc 146a to move along the axial direction. The press button 146c is disposed on the other side of the rotating disc 146a, and the press button 146c is connected to the rotating disc 146a through a cam mechanism. The compression spring 146d passes through the stopper pin disc 146b and the push button 146c, and is compressed between the pivot portion 124 and the push button 146 c. The stop pin 142 is disposed on the stop pin disc 146b, and the stop pin 142 normally passes through the through hole 124a to be inserted into the limit notch 134a.

As shown in fig. 15, 16, 17 and 18, after the press button 146c is pressed, the rotating disk 146a and the stopper pin disk 146b are driven to displace by the linkage of the cam mechanism; therefore, after the pressing button 146c is pressed, the stop pin 142 is driven to stretch and retract, so that the stop pin 142 is inserted into or separated from the limiting notch 134a through the through hole 124a, thereby fixing or releasing the pivot 130.

Referring to fig. 19, in the second and third embodiments, the pivot plate 134 further has a fixing notch 134b, and when the mounting plate 132 is parallel to the plane S, the blocking pin 142 is inserted into the fixing notch 134b, so as to temporarily fix the display 200, so that the display 200 can stably maintain the horizontal arrangement state, thereby facilitating the insertion of various connecting wires.

With the display stand 100 of the present invention, the display 200 can be effectively limited during normal use, and can be tilted forward and backward only at a limited angle. When the electric signal connector is required, the display 200 can be turned over to be in a horizontal state only by limiting the stop pin 142, so that a user can conveniently insert and withdraw the electric signal connector, and the whole display 200 is required to be moved and tilted for inserting and withdrawing the electric signal connector. After the electrical signal connector is plugged, the pivot 130 can be rotated again to restore the stand-up state of the display 200, and the base 120 can be lowered to adjust the height of the display 200 to the designated position on the stand 110. The stop pin 142 is simple to operate and can be quickly fixed or released.
