2. Description of the Related Art Input to a personal computer is generally performed by a keyboard, but a mouse is also attached to the keyboard to perform input for editing. On the other hand, recently, a touch panel has been used in various modes as one of effective input means, and one of them is being used in connection with a personal computer. In other words, a touch panel is added to the input means to the personal computer in addition to the keyboard and mouse, and the personal computer is used as a multipurpose personal computer.

When a touch panel is used by assembling it with a conventional personal computer, it is advantageous and necessary for the input operation that the touch panel can be easily attached to and detached from the front of a display such as a liquid crystal display panel. I have.
In the case of input using a keyboard, a mouse, or the like, the touch panel is unnecessary because it is unnecessary. In addition, not only an image on the display but also a copy of a certain original image is input. This is because it is possible to place a touch panel on the original image as shown in Fig. 1 and input the image by tracing the image with a pen or the like from above, and there is also a method of displaying the image on the display. .

[0004] One method has been proposed as a means for detachment. This is provided with hooking means on both sides of the fixing frame of the touch panel. This means uses a hooking shaft with a hook bent at a right angle, and its mechanism is specifically shown in FIG. 4 (side sectional view). In FIG. 4, there is a frame 34 for fixing the touch panel A. On both sides of these frames, a hooking mechanism is provided, which comprises a hook 36 for hooking, a notch step (about a half circle) 37, and a stopper 38 for the shaft. 35 and an elastic rubber 39 disposed opposite to the stepped portion 37. Here, the rubber 39 is fixed to the base 40. The right half of FIG. 4 shows a state in which the hanging shaft 35 is released from the rubber 39, and the left half thereof shows the hanging shaft 3
5 shows a state pressed by the rubber 39.

The hooking means can perform hooking and adjustment of the hooking position by the following operation. When the hooking shaft 35 is rotated, the coaxial is fixed to the rubber 39 or opened (moves up and down). This is because when the shaft 35 is rotated by the action between the step portion 37 and the rubber 39 and the step portion 37 comes to the position of the rubber 39, the coaxial 35 is opened and the up-down movement is possible, and Rotation is also possible. This state is shown on the right side of FIG. Therefore, the hooking position (up and down) can be adjusted in this state. Next, when the right shaft 35 is rotated 90 ° (the hook 36 is perpendicular to the fixed frame 34), the rubber 3
Since 9 touches the shaft, the shaft is pushed and stopped. This state is shown on the left side of FIG. When the hooking shaft 35 is to be rotated, it is difficult to hold the shaft 35 by hooking it on a personal computer or the like. Must be forced to rotate.

[0006]

However, the conventional method shown in FIG. 4 has the following problems and is not sufficiently satisfactory. One of the problems is that each time the shaft is rotated, the rubber may be damaged. That is, the rubber is easily scraped off by the edge of the step portion provided on the shaft, and the rubber is repeatedly removed. In many cases, chipping is caused by use. The second problem is that when trying to adjust the hooking position of the touch panel in accordance with the dimensions of various personal computers or the like, it is not possible to adjust the proper position in a hooked state with one touch. In other words, whenever the size of the personal computer or the like (display frame) changes, remove the touch panel and move the right and left axes by 1 each time.
It is necessary to determine the position one after another by raising and lowering, then rotate the shaft, fix it at a predetermined position, and finally perform a hooking operation, which is extremely poor in workability and lacks in quickness. .

The present invention has been achieved by solving the above two problems and conducting intensive studies in order to find a new attaching / detaching means. That is, it can be easily achieved by taking the following means.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a fixing frame for fixing a touch panel, which is provided with a hook portion at a tip end thereof, and a rod-shaped hook for freely moving and rotating in the axial direction. The present invention is characterized in that a locking mechanism including a shaft, a pressing means for pressing the locking shaft, and a push button for releasing the pressing means is provided therein. Further, a pressing means of the locking mechanism includes an arm having an appropriate fulcrum and an elastic body provided at one end of the arm for urging the other end and pressing the other end to the locking shaft. Is provided. A rubber elastic body is fixed to the arm and / or the hook shaft of the pressing means.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A frame body for fixing a touch panel to which the present invention is applied will be described. As is well known, a touch panel is one of information input means for inputting necessary information by pressing a touch-side electrode with a pen or a finger, and displaying and using the information on a display screen or the like. . In the configuration of the touch panel, for example, a transparent film having a transparent electrode pattern and a transparent plate are formed as substrates on a touch side and a display side, respectively, and both are arranged to face each other via an insulating spacer to form one panel plate. This is fixed to a frame made of plastic or the like, and a touch panel with a fixed frame is completed and commercialized. The specification of the fixing frame is basically determined by the size of the panel plate, but the overall shape is various depending on the design and the preference of each manufacturer. The present invention
Since such various frame specifications can be quickly dealt with, there are no restrictions on such frame specifications.

[0010] The touch panel fixed to the frame is
When used as a single information input device in combination with a personal computer, etc., the input information from the touch panel is displayed on the display of the personal computer, etc., and is immediately viewed through the touch panel to perform the next input. Will be. In addition, when operating without using the touch panel, the touch panel becomes an obstacle. Therefore, when used in combination, it is desired that the touch panel be able to operate its position easily and quickly so as to accurately fit the screen of a personal computer or the like.
In the present invention, this is achieved by the following latching means.

The above-mentioned hooking means is provided with a hooking mechanism having the following three configurations in a frame for fixing the touch panel. One of the constitutions is a rod-shaped hanging shaft, which is provided with a hook (generally a fishing type) for hooking on a personal computer or the like, and a stopper for preventing it from coming off. The hooking shaft is in a state in which it can freely move up and down or rotate (360 °). The vertical movement is to easily adjust the position of the touch panel on various personal computers, etc. The rotation is to freely rotate the hook 360 ° to prepare for hooking, or use it after removing from the personal computer. If you do
This is for storing the hook portion so that it does not come out of the fixed frame.

The hanging shaft is made of metal such as stainless steel or plastic, and is generally a round bar, but may be a polygonal bar. Diameter (average) is generally 3-6 mm
And the length is 1/1 to 1/1 / of the vertical length of the fixing frame.
It is about 4. The fishing hook of the hook portion is not particularly limited, and may be a right-angled shape, a curved (angle-shaped) shape, a square shape, or the like.

The pressing means is means for creating a state in which the locking shaft is pressed, and presses the coaxial when the touch panel is hooked on a personal computer or the like, or when the touch panel is not used. It is stopped so as not to move up and down and rotate. The state in which vertical movement and rotation are possible is limited to the case where a push button described later operates. Specifically, the pressing means can be exemplified by the following two examples, but is not limited thereto, and may take any mechanism as long as it performs the same function as described above.

[0014] In Example 1, as shown in Figs. 1 and 2, the hooks (7, 17) and the arms (5, 15) with elastic springs (9, 18) are used for the latching. Shaft (2, 1
1) Lower end portion (with respect to the fishing tip portion)
Is a mechanism that is always held down. This is done by applying the lever principle.

One arm (generally made of metal) shorter than the length of the hanging shaft is provided along with the hanging shaft. The arm has a fulcrum (projection) for supporting the arm at a position near the center and an elastic spring (for example, a coil spring, a leaf spring, etc.) at the tip of the arm and at a position opposite to the fulcrum. )
Is fixedly provided. Here, the elastic spring means that the arm is always fixed in a state where the arm pushes the locking shaft. Thereby, the above-mentioned normal state is maintained.

A push button is provided at a hand end of the arm so that when required, the state of the arm of the latch shaft released by the arm is released, and the push button can freely move up and down and rotate 360 °. It is for the purpose of exercising. Even if the push button is pressed one-touch, the latching shaft is easily opened, and the latching shaft is instantly fixed when the hand is released. Therefore, even if the touch panel is hooked on the frame of a personal computer or the like, the position can be easily adjusted. Here, the material, state, mechanism, and the like of the push button are not particularly limited. The above will be described in more detail in Example 1 below.

As another example, a block-shaped support is used, and an elastic spring (or elastic rubber) and a push button are attached to the block-shaped support, so that the fixing and releasing of the locking shaft can be performed in one touch. There is also a way to do it. In other words, this is a plastic (or metal) one in which the mounting part of the elastic panel and the part to be the push button are integrated and a hole with a diameter larger than the diameter of the hooking shaft is drilled at the center. If there is a block-shaped thing, an elastic spring that attaches the hooking shaft to this center hole is attached, and this always pushes the hooking shaft and keeps it in the pressed state, it is in the fixing state in the normal state, If the user wants to release it, the user only has to press the push button. Although this latching mechanism is different from the above-described lever-based leverage of the arm, it can be said to be one latching mechanism according to the present invention. Note that, in order to perform fixing more reliably, it is preferable to provide rubber in a state of being slightly hung over the hole. This will be described in more detail with reference to a second embodiment.

When the touch panel is used by hooking it on a personal computer or the like, contact between the two frames cannot be avoided.
There is also a danger that the frame surface will be damaged by contact. Further, when the personal computer or the like shakes or vibrates, there is a risk of displacement of the touch panel only by hooking by the hook portion. As a measure to prevent this, for example, the frame for fixing the touch panel of the present invention (the side in contact with the frame of a personal computer or the like)
A rubber elastic body such as synthetic rubber, urethane rubber, silicone rubber, or the like can be adhered to the above.

The latch mechanism formed by combining the above three mechanisms is provided inside the touch panel fixing frame. The number and positions of the mechanisms are determined by using two sets of the mechanisms. It is desirable to provide on both sides of the fixed frame. However, it is also possible to use one set and provide it at the center of the fixed frame. In such a case, it is preferable to attach a stabilizing member to the tip of the hook of the hooking shaft. This stabilizing member is intended to be hooked on a frame of a personal computer or the like with a larger area, so that it can be stably hooked without swinging left and right. Although there is no particular limitation on the internal method, it is preferable that the portion to be pressed by the push button is slightly protruded from the touch panel fixing frame.

According to the present invention, as is apparent from the above description, since the latching shaft is in the depressed state in a normal state, this is a simple one-touch operation of the push button, and the latching operation of the touch panel to the personal computer or the like is easily performed. It is something that makes it easy. For example, assuming that the hooking position does not match, if the touch panel is above the center of the personal computer, if the push button is pressed while it is hooked, the touch panel descends even under its own weight. Conversely, if it is below the center, remove it from the personal computer once, press the touch panel itself while pressing the push button with the hook part of the hooking shaft on the plane, and the hook part will retract. Therefore, the length can be shortened and can be adjusted to the center position between the two. It can be said that this is a latchable touch panel fixing frame having an extremely simple action mechanism.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

Embodiment 1 First, a concrete example according to claim 2 will be described with reference to plan views of FIGS. In FIG. 1, reference numeral 1 denotes a plastic frame having a predetermined shape for fixing a touch panel A having a predetermined size. Is shown. That is,
The right side shows the open (up and down, left and right movement) state of the locking shaft,
The left side shows the state of pressing. This is done by the following mechanism. There is a hooking shaft 2 made of a stainless steel rod having a curved hook portion 3 and a stopper 4 for preventing it from coming off. The hooking shaft 2 has a fulcrum 7 as a means for pressing it. A bent, plate-shaped stainless steel arm 5 supported by the arm is provided along with the arm. still,
A rubber 6 is fitted to a tip portion of the arm 5 (a portion in contact with the locking shaft 2 when the push button 8 is not pressed). By the presence of the rubber 6, the pressing is more reliably performed. Of course, the rubber 6 may be fitted to the hook shaft 2.

A push button 8 is provided at the end of the hand around the fulcrum 7 of the arm 5, and a coil spring 9 is provided at the other end. Since the coil spring 9 always presses the arm 5 and the latching shaft 2 is pressed by the rubber 6, the latching shaft 2 cannot freely move up and down and rotate freely (left side view). ). However, if the push button 8 is pressed with one touch, the latching shaft 2 is instantly released from the pressing (right side view).

FIG. 2 shows a modification of FIG. 1 in a side sectional view. In this case, the vertical movement of the locking shaft 11 is performed at regular intervals. The operating state is shown on the left and right sides. In other words, the right side shows a state in which the hooking shaft 11 is open and can freely move up and down (360 °), and the left side shows a state in which the hooking shaft 11 is fixed at a predetermined position and can be hooked. I have.

The following latching mechanism is provided on both sides of the plastic fixing frame 10 to which the touch panel B is fixed. The hooking shaft 11 includes a hook portion 12 and a stopper 13 for preventing the hook portion 12 from coming off with a toothed portion 14 provided with a groove 14a for performing vertical movement at a constant pitch. Here, the tooth 1
4 are provided with the protrusions 1 provided at the tip of the arm 15.
6 for biting. The amount of vertical movement of the hanging shaft 11 varies depending on the pitch of the groove 14a to be cut. The hanging shaft 11 is supported by a support 21 provided in the fixed frame 10.
And 22 and the fixing frame 10 are respectively supported by passing through through holes (not shown in the drawing). As means for pressing the locking shaft 11, a horizontal plastic arm 15 and a coil spring 18 are provided.
The tip of 5 is provided with a protrusion 16 for engaging the groove 14a of the toothed portion 14, and a coil spring 18 is fixed so that the protrusion 16 is always pressed against the locking shaft 11. . Since the arm 15 operates according to the lever principle, a substantially intermediate position of the arm 15 is supported by the fulcrum portion 17. Reference numeral 20 denotes a fixed base that supports the fulcrum 17. The release of the pressing state is performed by the push button 19,
This is attached to the arm 15 at the hand position.

By pressing the push button 19, the arm 1
Since the projection 16 at the tip of No. 5 can be separated from the groove 14a of the hanging shaft 11, the hanging shaft 11 is opened (shown in the right half of FIG. 2). When the hand is released from the push button 19, the convex portion 16 is immediately engaged with the groove 14a of the locking shaft 11, and is in a pressed state, and is in a state of being hooked on a personal computer or the like. In the case of FIG. 2 (shown in the left half of FIG. 2), as in FIG. 1, the above operation can be performed quickly with a single touch of a push button.

Embodiment 2 Here, a locking means by a mechanism different from that of Embodiment 1 is shown in FIG.
Examples are shown by (A) and (B). In the figure, push button 3
0, and a hole 33 through which the hanging shaft 24 is inserted.
A plastic block-shaped pressing body 29 provided with an elastic rubber 28 buried over a part of the
And a state in which it is provided on both sides of the touch panel fixing frame 23.

Specifically, the fixed frame 23 of the touch panel C
(The lower side of the frame is omitted), and a locking mechanism is provided on the left and right sides of the fixed frame 23. The left side shows a state in which the locking shaft 24 is open (movable vertically and horizontally), and the right side shows a state in which the locking shaft 24 is pressed. The locking mechanism is as follows. . The plastic block-shaped pressing body 29 is integrally formed with a recess for fixing the push button 30 and the coil spring 31, a hole 33 for inserting the locking shaft 24, and an elastic rubber 28 buried over a part of the hole 33. It has a simplified structure. The size of the hole 33 is larger than the outer diameter of the hook shaft 24 so that the elastic rubber 28 is brought into a non-contact state when the push button 30 is pressed.

The block-shaped pressing body 29 is fixed to the fixed frame 2.
3 are disposed in storage frames 32 provided on the left and right sides. At this time, the locking shaft 24 is inserted through fitting holes (not shown) formed in the fixed frame 23 and the storage frame 32 and holes 33 provided in the block-shaped pressing body 29 so as not to come off. A stopper 27 is attached to the tip. A coil spring 31 for constantly pressing the block-shaped pressing main body 29 to press and fix the locking shaft 24 is attached to the concave portion on the opposite side of the push button 30.

The hooking shaft 25 has a right-angled hooking portion 25, and further has a hooking assisting end fitted with a rubber tube so as to be perpendicular to the hooking portion. A bar 26 is provided horizontally. This hook auxiliary rod 2
6 (which may be plate-shaped) can be suspended more stably (rolling, etc.) on a personal computer or the like. However, this is not required.

When the push button 30 is pressed, as shown in the left side of the sectional view, the elastic rubber 28 is separated from the pressed locking shaft 24, and the locking shaft 24 is released. Since the vertical movement and the rotation (360) are free, it is possible to adjust the hook position. When the hand is released from the push button 30, as shown in the right side of the sectional view, the hooking shaft 24 is immediately pressed by the elastic rubber 28 to be in a pressed state.
The elastic rubber 28 may be fitted to the side of the hook shaft 24, but is not essential, so it need not be used.

When the touch panel is used by hooking it on a personal computer or the like, contact between the two frames is inevitable. However, there is a risk that the contact may damage the frame surface. In addition, when PCs shake or vibrate,
There is also a risk of displacement of the touch panel only by hooking by the hook portion. As a countermeasure to prevent this, for example, a rubber elastic body such as synthetic rubber, urethane rubber, or silicone rubber can be attached to the touch panel fixing frame (the side in contact with the frame of a personal computer or the like) of the present invention.

Since the present invention is configured as described above, the following effects are obtained. First, when the touch panel is used by hooking it on personal computers of various sizes, the hooking position can be easily and quickly adjusted and determined with one touch.

Even when the elastic rubber is used for the hooking mechanism, the elastic rubber is not damaged at all by use, and the use durability is semi-permanent.

Further, even when the touch panel is hooked on the personal computer or the like, the personal computer or the like may swing or vibrate, causing a positional shift or damaging the frame of the personal computer or the like due to contact. The property is small.
