Description

TECHNICAL FIELD [0001] The present invention relates to a monitor mounting mechanism and a force device including the monitor mounting mechanism.

The present invention relates to a monitor mounting mechanism, and more particularly, to a monitor mounting mechanism capable of detachably fixing a monitor to a stand without a fastening means such as a separate screw piece, And more particularly,

Typically, a monitor device such as a force terminal monitor, a computer monitor, and an LCD (LED, PDP) TV is fixed on a wall surface or put on a desk or the like through a mounting mechanism such as a hanger or a stand depending on the use environment.

In the conventional monitor mounting mechanism used for installing the display device on a wall, a desk, or the like, a mounting member is formed on a hanger or a stand, and the mounting member is fastened to the monitor device using screws or the like, It is a common practice. However, since the screw fastening method requires a separate component (i.e., a screw piece or the like), and a tool such as a screwdriver is required at the time of fastening or disassembling it, there is a disadvantage that the assembly and detachment of the monitor is troublesome.

In order to overcome this disadvantage, a mounting mechanism is known in which a hook is formed in a mounting member and a hook is formed in a monitor to fix the monitor by a hook engagement by a hook. However, as described above, There is a limitation in that a stable and stable connection state of the monitor can not be assured. That is, in this case, since the monitor is coupled to the coupling plate in a floating state, even if the monitor is lifted up a little, the hook may be detached from the hook catching groove and eventually the monitor may be detached from the coupling plate. But also eventually requires additional fastening means such as screws.

In addition, as shown in the Korean Utility Model Application No. 2011-0002867, it is possible to improve the convenience of assembling / separating the monitor in the case of the coupling mechanism using the magnetic force, but if an external force larger than the magnetic force is applied to the monitor, There is a disadvantage that can occur.

In order to solve the problems of the conventional monitor mounting mechanism, the applicant of the present invention has filed a Korean Registered Utility Model No. 20-0469675. However, in the case of Korean Registered Utility Model No. 20-0469675, when the lock lever is particularly worn due to repeated use of the lock lever, or when an external shock or vibration is applied, the lock lever unexpectedly deviates from the clearance space It has been found that the monitor may be detached from the support.

In the following, preferred embodiments, advantages and features of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front perspective view of a monitor mounting mechanism according to the present invention, FIG. 2 is a view showing a monitor mounting mechanism according to the present invention, Fig. 5 is a view showing the state after the monitor mounting mechanism according to the invention is attached to the monitor.

1 to 3, the monitor mounting mechanism according to the present invention includes a coupling plate 10, a hook 30, a hook engagement groove 41, a lock jaw 44, a lock lever 20, 60, and a stopper 70, and the monitor 40 is provided with a space for interference fit of the lock lever 20.

For reference, the monitor referred to in the present invention means a display device of a wide meaning including a force terminal monitor, a computer monitor, and an LCD (LED, PDP) TV. (Hereinafter referred to as a "stand") placed on a hanger, a desk, or the like.

The coupling plate 10 of the monitor mounting mechanism is formed of a plate-shaped member, one side of which is connected to a support, and the other side of which is detachably coupled to the monitor. The coupling plate 10 is formed in a rectangular shape (preferably rectangular or square) parallel to at least a pair of longitudinal sides parallel to each other at least so that the coupling plate 10 is inserted into the seating groove 43 of the monitor 40, It is possible to smoothly move upward in the seating groove 43 while being guided by both longitudinal inner wall surfaces of the seating groove 43 when inserting the locking lever 44 into the seating groove 43. As a result, So that it can be generated. Details of this will be described later.

On one surface of the coupling plate 10, a rotation means 51 is formed so that the support plate can be rotatably engaged with the coupling plate 10. For reference, in the case of the embodiment shown in FIG. 1, the turning means 51 is constituted by a fixing table having a hinge.

The hook 30 is protruded from one surface of the coupling plate 10 (that is, a surface attached to the rear surface of the monitor 40) and fastened to the hooking recess 41 formed in the monitor 40, So that it is fixed on the coupling plate 10.

It is preferable that the hooks 30 are configured so as to have a cross-sectional shape of '┛' shape fixed at one end of the coupling plate 10 at one end and at least one so as to stably support the monitor 40 .

The hook engagement groove 41 is provided in the rear surface of the monitor 40 and more specifically in the area of the seating groove 43 formed on the rear surface and the engagement plate 10 is provided in the seating groove 43 of the monitor 40 The hook 30 is formed at a position corresponding to the hook 30 of the coupling plate 10 at the time of insertion and insertion so that at least the hook 30 can be inserted.

When the hook 30 of the coupling plate 10 is fitted into the hook engagement groove 41 of the monitor 40 and the monitor 40 is pushed downwardly of the coupling plate 10 by the above- The hook 40 is hooked and supported by the hook 30 so that the monitor 40 is assembled and fixed to the coupling plate 10.

However, when the monitor 40 is supported only by the hook 30 as described above, it is impossible to guarantee a stable and stable connection state of the monitor 40. [ That is, in this case, since the monitor 40 is coupled to the coupling plate 10 in a state of being able to move, the hook 30 is detached from the hooking recess 41 even when the monitor 40 is slightly lifted up Eventually, the monitor 40 may be separated from the coupling plate 10.

The lock lever 20 and the lock jaw 44 of the present invention are components for solving such a problem. The lock lever 20 is rotatably mounted on the coupling plate 10, Thereby preventing the engagement grooves 41 from being released.

The lock jaw 44 is protrudingly formed on the back surface of the monitor 40 so as to have a stepped jaw shape so that the lock lever 20 is held between the engaging plate 10 and the lock jaw 44 engaged with the monitor 40, And functions to support the lock lever 20 which is in the space.

1 and 2, a seating groove 43 is formed on the rear surface of the monitor 40 so that the coupling plate 10 can be inserted into the seating groove 43, And a step jaw 42 on the lower end side of the seating groove 43 serves as a lock jaw 44. The lock jaw 44 is formed by a stepped jaw 42 protruding in the shape of a quadrangle on the back surface.

The seating groove 43 is provided on the rear surface of the monitor 40 in the form of a recess having an area larger than at least the area of the coupling plate 10 so that the coupling plate 10 can be inserted and seated. The longitudinal length (or the transverse length) of the seating groove 43 is formed to be at least larger than the longitudinal length (or the transverse length) of the coupling plate 10 so that the coupling plate 10 is engaged with the seating groove 43 A space is formed between the lower end (or the side surface portion) of the plate 10 and the lower end portion (or the side surface portion) of the seating groove 43 by a predetermined width.

2, the seating grooves 43 and the coupling plate 10 are formed in a rectangular shape, and both side edges of the seating groove 43 are formed to be larger than both side lengthwise sides of the coupling plate 10, The locking lever 20 is configured to generate the spaced space between the lateral side of the lower end of the coupling plate 10 and the lower end stepped surface 44 of the seating groove 43 when the locking lever 20 is seated in the seating groove 43, And the pivot shaft 23 is provided in the lower region of the coupling plate 10.

The monitor locking device according to the preferred embodiment of the present invention is configured such that the stepped jaw on the lower end side of the seating groove 43 that generates the spacing space with respect to the lower end of the coupling plate 10 functions as the lock jaw 44 of the present invention And the spacing space is configured to function as a fitting groove in which the lock lever 20 is inserted in an interference fit manner.

The lock lever 20 according to a preferred embodiment of the present invention is rotatably mounted about the lower end edge of the coupling plate 10 and specifically includes a rod-like cross bar 21 and a cross bar 21 And a pair of vertical legs 22 formed at both ends to enable the rotary motion of the crossbars 21.

The locking lever 20 is configured to prevent at least a portion of the monitor hooks hooked to the coupling plate 10 from being disturbed in the spacing space between the locking tab 44 and the coupling plate 10, For example, the bar-shaped cross bar 21 is configured to be pressed against the spacing space.

As shown in FIG. 1, the pair of vertical legs 22 are each formed in a pair of bar shapes bent at both ends of a cross bar 21, The lock lever 20 is coupled to the coupling plate 10 in a rotatable manner by being coupled to the hinge 23 on the lower side of the left side and the right side of the lock lever 10, respectively.

The locking lever 20 of the present invention preferably further includes a unlocking handle 24 and the locking tab 44 is further formed with a handle groove 45. [

The unlocking handle 24 is a component that facilitates the unlocking operation of the lock lever 20 when the monitor 40 is to be detached from the coupling plate 10. Specifically, So that the lock lever 20 can be easily pulled up by pulling up the lock lever 20 which is held in a spaced space between the lock lever 20 and the lock jaw 44, As shown in Fig.

The unlocking handle 24 according to the preferred embodiment is formed as a piece of rectangular parallelepiped protruding from the crosspiece 21 of the lock lever 20. [ The lock jaw 44 is formed with a knob groove 45 formed in the shape of a groove so that the unlocking knob 24 can be inserted into the knob groove 45. The knob groove 45 has an upper end and a lower end, The lower end of the knob 24 is exposed to the outside by the opened lower end of the knob groove 45 when the knob 24 is inserted into the knob groove 45 by the interference fit of the knob 20, The lock lever 20 can be easily rotated in the separating direction by raising the lower end portion of the handle 24 for use.

The monitor mounting mechanism of the present invention can detachably fix the monitor to the support stand without the use of a separate fastening means such as a screw piece.

In this case, when the lever 20 is repeatedly used, the lock lever 20 may be unintentionally caught in the gap 21, So that the monitor may be detached from the support.

In order to solve such a problem, the monitor mounting mechanism of the present invention is characterized in that it includes a latching portion (60) and a stopper (70).

Fig. 4 is a perspective view of the main part of the monitor mounting mechanism according to the present invention. Fig. 2 and 4, the locking part 60 of the present invention is formed at the rear area of the monitor corresponding to at least the area of the pivot shaft 23 of the lock lever 20, So that it can be temporarily blocked.

According to the preferred embodiment of FIGS. 2 and 4, the latching portion 60 is formed in the shape of a latching protrusion of a rectangular parallelepiped protruding in a stepped jaw shape with respect to the back surface (i.e., the seating groove surface) of the monitor

When the engaging plate 10 is engaged with the monitor and the lock lever 20 is in a state in which the engaging plate 10 and the lock jaw are in a detached space, The upper surface 61 of the locking portion 60 is positioned at a vertical lower portion of the lock lever 20 at least in the area of the pivot shaft 23.

Here, the upper surface 61 of the latching portion 60 refers to a surface on which contact with the stopper 70, which will be described later, occurs when the lock lever 20 is rotated.

1, if the rotary shaft 23 of the lock lever 20 is configured as a hinge shaft type and the hinge shaft is provided on the vertical base 22 of the lock lever 20, 60 may be formed in a stepped shape formed in the vertical lower region of the hinge axis formed in the vertical base 22 as in the embodiment of FIG.

The engaging portions 60 may be constituted by one, but preferably two. In other words, each of them may be formed in each of the regions corresponding to the respective hinge axes of the pair of vertical bars 22 in this case.

The stopper 70 of the present invention is engaged with the above-described latching portion 60 during the rotation operation of the lock lever 20 to temporarily stop the rotation operation of the lock lever 20, And functions to enable the locking lever 20 to rotate in a deteriorated state.

The stopper 70 may be formed at a portion of the lock lever 20 connected to the pivot shaft 23. According to the preferred embodiment of FIG. 4, the stopper 70 is formed in the shape of a jaw formed at a corner of the hinge region of the lock lever 20, that is, at one corner of the longitudinal end 22, more preferably at a right angle And may be formed in the shape of a jaw formed into a square.

The bottom surface of the locking lever 20 extending from the cross bar 21 to the stopper 70 in this case is formed to be in contact with the engaging portion 10 And at least the stopper 70 is configured to be in contact with the upper surface 61 of the engaging portion 60. In this case,

With the above-described configuration, when the lock lever 20 in the locked state (that is, the locked state in the detachment space) is lifted upwards by external impact, vibration, or the like, (70) is engaged with the engaging portion (60) to prevent the rotation of the lock lever (20).

Accordingly, it is possible to prevent the accident that the user unintentionally detaches the lock lever 20 from the spacing space and separates the monitor from the support.

On the other hand, when the user intends to release the lock lever 20 from the spacing space, when the user applies a rotational force of a threshold value or more, the locking lever 20 is retracted by the tension of the locking portion 60 itself, And thus the lock lever 20 is released from the rotation stopping state by the stopper 70, so that the lock lever 20 can be smoothly rotated again.

Here, the "rotational force of the critical point or more" means an external force greater than or equal to a stoppage force applied to the upper surface 61 of the stopper 70 by the stopper 70. [

FIG. 5 is a side elevational view for explaining a stopper according to another embodiment of the present invention. FIG. 5, the stopper 75 according to another embodiment is formed in a protruding shape on the hinge region of the lock lever 20, that is, on the outer surface of the end portion of the vertical base 22.

Specifically, the stopper 75 of the embodiment of FIG. 5 may be formed as a bar-shaped protrusion or a protrusion-shaped protrusion, and the bar-shaped or protrusion-shaped stopper may be provided in a plurality of stoppers.

In this case, when the lock lever 20 in the locked state (i.e., the locked state in the detached space) is lifted upwards by an external shock, vibration, or the like, the lock lever 20 is bar- The stopper 75 of the lock lever 20 can be prevented from unintentionally rotating (that is, unlocking) when the stopper 75 of the lock lever 20 comes into contact with the lock portion 60 and is engaged.

FIG. 6 is a combined state view showing a state in which a monitor and a support are coupled to the monitor mounting mechanism of the present invention. 6, when the lock lever 20 is rotated at a predetermined angle (preferably 45 degrees or more) with respect to the coupling plate 10, the hook 30 of the coupling plate 10 and the hook 30 of the monitor 40 The engaging plate 10 is inserted into the seating groove 43 of the monitor 40 and is inserted between the upper end of the engaging plate 10 and the upper end of the seating groove 43 A space is generated.

In such a state, when the monitor 40 is pushed downward, the hook 40 is hooked and held by the hook 30 due to its own weight so that the monitor 40 is assembled and fixed to the coupling plate 10 do. At the same time, the above-described spacing space is generated between the lower end of the coupling plate 10 and the lower end stepped surface of the seating groove 43 (i.e., the locking tab 44).

When the monitor 40 is assembled and fixed to the coupling plate 10 by the hook 30, the locking lever 20 is rotated downward so that the coupling plate 10 and the locking jaws 44 (I.e., in the locked state), thereby completing the monitor mounting.

Even if the monitor or support is subjected to an external shock or vibration or the lever 21 is excessively worn in particular, the lock lever 20 is in a state in which the user (I.e., locked state) by the rotation stopping operation by the stoppers 70, 75 and the engaging portion 60 as long as the rotation force exceeding the above-mentioned critical point is not applied, .

On the other hand, the monitor mounting mechanism of the present invention described and illustrated above is particularly applicable to a force device. The POS device is a widely used terminal for performing price calculation and sales management of each merchandise purchased by a purchaser, and includes a microprocessor for performing information calculation and processing, a monitor for visually displaying information, And a card reader.

The monitor mounting mechanism of the present invention is coupled to the monitor side of the force device to function to support the force device.

Although the preferred embodiments of the present invention have been illustrated and described using specific terms, such terms are used only for the purpose of clarifying the present invention, and the embodiments of the present invention and the described terminology should be construed to cover the technical scope and scope of the following claims It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention.

For example, although the lock lever 20 is mounted on the coupling plate 10 so that the coupling plate 10 is rotatable about the axis, the locking lever 20 is rotated on the back surface of the monitor instead of the coupling plate 10 It is of course possible to achieve the same purpose (that is, to prevent separation of the coupling plate hook) by constructing the coupling member so as to realize the above-described interference fit operation.

Such modified embodiments should not be individually understood from the spirit and scope of the present invention, but should be within the scope of the present invention.
