Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to electronic devices and the like.
[0002]
[Prior art]
2. Description of the Related Art Due to significant technical progress in recent years, electronic devices such as notebook personal computers have come to provide various sizes and versatile functions according to user demands. However, in a notebook personal computer or the like, only one unit in which two casings are connected, that is, only the basic configuration of “folding in two”, the old state is still unchanged. This is the reason that in a conventional notebook personal computer or the like, portability tends to be hindered as the size increases, and portability tends to be hindered as the size increases.
(Japanese Unexamined Patent Publication Nos. 2000-18426, 2001-282129, 2002-140133, 11-15397, 10-63393, 2002-182823, JP-A-2002-99371, JP-A-2002-169641, JP-A-2002-73255, JP-A-2002-73251, JP-A-2000-56904)
[0003]
[Problems to be solved by the invention]
Taking a laptop computer as a specific example among various electronic devices, even if the final volume is the same, a thin, large-sized two-fold laptop computer can be folded more compactly and in multiple layers. Compared to a notebook computer, the latter is likely to be more portable. Therefore, in the present invention, it is an object of the present invention to obviate the limitations of the prior art, and to make multiple folding of electronic devices including notebook computers.
[0004]
[Means for Solving the Problems]
The outline of the problem solving means is as follows.
[0005]
When folding the display, an arbitrary display device such as a fixed LCD or a flexible LCD is used, and a continuous screen is formed over a plurality of casings. In particular, when the flexible LCD is used, the "flexibility adjuster" The "composite tensor" consisting of pillars, runners and rails creates tension in both the vertical and horizontal directions while adjusting the bending rate.
[0006]
On the other hand, in folding the keyboard, the "specific arrangement order" and "intentionally irregular arrangement" of the keys, which are customary to suppress mistyping, are not broken, and the volume of the product is reduced. Adopt "regular alternating arrangement" which does not increase unnecessarily.
[0007]
Furthermore, unlike a conventional folding electronic device such as a notebook personal computer, a “joining surface” is inevitably exposed in a multi-fold electronic device. Therefore, as a key of the present invention,
a) The "joining surface" of each casing at the time of folding is reliably protected.
b) Automatically repositions during deployment and does not impede any continuity of the screen or any conventional arrangement of keys.
c) Upon further folding, it automatically returns to its original position and again protects the "joining surface" of each casing.
d) In addition, these operations are automatically performed in conjunction with opening and closing of each casing, and do not require extra operation procedures or power consumption.
We propose a "joint surface protection cover unit" having such a function and an "elastic hinge unit" as its main component.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
1) Foldable display with fixed LCD
2) Foldable display with flexible LCD
3) Foldable keyboard
4) Multiple folding electronic devices
The following four items will be sequentially described as specific examples.
[0009]
(Embodiment 1) In this section, a specific example of a foldable display using a fixed LCD will be described.
[0010]
An LCD (Liquid Crystal Display) usually functions like a single plate that functions while maintaining a certain shape, and cannot be folded like "paper" itself (hereinafter, this is referred to as a fixed LCD). And). Therefore, in folding the display, it is necessary to fit a fixed LCD into each of a plurality of casings, and then connect the casings physically and electrically.
For the physical and electrical connection between the casings, as shown in FIG. 1, a uniaxial hinge 2 which rotates about a joint line on the development surface side of the casing 1 as a central axis is used, and is further shown in FIG. As described above, the uniaxial hinge 2 is installed at the end of the casing 1. In this case, the fixed LCDs 4 can be arranged side by side on the development surface of the casing 1 without any gap, and a substantially continuous screen can be formed.
[0011]
Instead, when the casing 1 is folded as shown in FIG. 3, there is a structurally unavoidable problem that the end of the fixed LCD 4 is exposed at the joint surface 5 of the casing 1. Because it is directly received, it can not withstand the mobile at all. Therefore, what is absolutely necessary is a cover for protecting the joining surface 5.
However, if the cover is simply attached simply to protect the joint surface 5, the casing 1 is fixed in a folded state by the presence of the cover over the joint surface 5 and cannot be deployed. However, it is not preferable from the viewpoint of convenience to attach and detach the cover by hand each time the user unfolds or folds. On the other hand, if a complicated automatic attachment / detachment mechanism is provided, the whole volume is greatly increased, which leads to a decrease in portability.
Therefore, the elastic hinge unit 6 shown in FIG. 4 is used as an example of a means capable of automatically moving the cover in accordance with the expansion and folding while having a small volume. By the way, this figure is intentionally enlarged for the sake of clarity, but the actual size used is very small.
The elastic hinge unit 6 in this figure is a combination of an elastic strap 7 made of a rubber material or the like and a plurality of hinge frames 8 made of a metal material or the like. (Elasticity).
[0012]
5 to 7 schematically show how the elastic hinge unit 6 actually works. It should be noted that in FIGS. 5 to 7, the illustration of the one-axis hinge is omitted for the sake of simplicity.
FIG. 5 schematically shows a state in which the joint surface protection cover 10 and the casing 1 in a folded state are connected by an elastic hinge unit 6 passing through a shaft. In this figure, the joint surface of the casing 1 is securely protected. By the way, if the conventional hinge is used instead of the elastic hinge unit 6, since the shape of the hinge itself is constant and has no elasticity (elasticity), the joint surface protection cover 10 and the casing 1 are shown in FIG. And the casing 1 cannot be deployed.
FIG. 6 schematically illustrates a state in which the joint surface protection cover 10 moves as the casing 1 is unfolded. When the casing 1 is to be unfolded, the "extruding force" due to the corner of the casing 1 is applied to the joint surface protection cover 10 and the elastic hinge unit 6 is extended, so that the joint surface protection cover 10 naturally moves to its position. Can be changed. That is, since the movement of the joint surface protection cover 10 is automatically performed in conjunction with the opening and closing of the casing 1, an extra operation procedure and power consumption are unnecessary.
FIG. 7 shows a state in which the casing 1 is unfolded 180 degrees. At this time, since the "extruding force" by the corner of the casing 1 has not been applied yet, the elastic hinge unit 6 naturally contracts, and the joint surface protection cover 10 comes into close contact with the bottom surface of the casing 1. Then, the regular LCD on the development surface becomes a substantially continuous screen without hindering its continuity.
5-7, the casing 1 in the deployed state can be folded again.
In short, the joint surface protection cover 10 is indispensable to protect the joint surface of the casing 1, and at the same time, when the casing 1 is opened and closed, the joint surface protection cover 10 is moved without any extra operation procedures or power consumption. The hinge unit 6 is indispensable. In other words, the "joining surface protection cover unit" in which these are linked is indispensable for realizing the foldable display.
[0013]
The above is a specific example of forming a foldable display using a fixed LCD.
Incidentally, in the above description, the LCD is particularly used as the display device, but an actual display device may be used as needed.
In the above description, the joint surface protection cover 10 and the casing 1 are connected by the elastic hinge unit 6. However, if the movement of the joint surface protection cover 10 as shown in FIGS. Instead of the hinge unit 6, a simple elastic band formed of only a rubber material or an elastic hinge frame formed of only a rubber material may be used. However, in the former case, the connection with an adhesive is required, so the durability of the bonded part remains questionable. In the latter case, the rotation of the shaft hole is reduced due to the frictional resistance of the material attached to the rubber material, or the rotation is sufficient. It is assumed that the hinge connection is loosened by providing a margin for the shaft hole in order to obtain the property. Therefore, it can be said that the use of the elastic hinge unit 6 is preferable as long as the problems such as the durability of the bonding portion and the turning property of the shaft hole cannot be solved.
[0014]
In addition, the correlation between the elasticity (stretchability) and the durability of the elastic hinge unit 6 will be added here, but it can be said that both are in a negative correlation (inversely proportional). In other words, in the elastic hinge unit 6, if the elastic strap is made soft to increase the elasticity (stretchability), the durability is reduced. On the contrary, if the elastic strap is made hard to increase the durability, the elasticity (stretchable) is obtained. Sex) is reduced.
Originally, it is not preferable that such an alternative situation is reversed, but in the present invention, since the following two conditions are already satisfied, there is no problem in giving priority to the latter.
The first of the conditions is the expansion ratio required for the elastic hinge unit 6. As shown in FIGS. 5 to 7, the expansion and contraction rate of the elastic hinge unit 6 due to the opening and closing of the casing 1 is small, and does not require significant expansion and contraction.
The second condition is the amount of force required for the elastic hinge unit 6 to expand and contract. As shown in FIGS. 5 to 7, when the casing 1 is opened and closed, a “push-out force” by the corner of the casing 1 is applied to the joint surface protection cover 10, which means that the principle of “lever” works. As is well known, when moving something using the principle of "lever", it is only necessary to have one-eighth the force as compared with the case of using completely bare hands.
That is, as shown in FIGS. 5 to 7, in the combination of the casing 1, the elastic hinge unit 6, and the joint surface protection cover 10, the above two conditions are already satisfied, and therefore, the durability of the elastic hinge unit 6 is This means that the elastic straps can be made rigid to enhance the performance. Of course, even if it is hard, if it is so hard as to have no elasticity (stretchability) as in the conventional hinge, the meaning of "elasticity" in the elastic hinge unit 6 is lost. It is necessary to take care not to hinder the free movement of the joint surface protection cover 10 shown in FIGS. Further, the elasticity (stretchability) required of the elastic hinge unit 6 changes depending on the situation such as the size of the casing and the like.
[0015]
(Embodiment 2) In this section, a specific example of a foldable display using a flexible LCD will be described.
[0016]
The LCD can be made bendable by using a flexible substrate in addition to a conventional fixed-type substrate (hereinafter, referred to as a flexible LCD). However, the flexible LCD is not “paper” even if it can be folded freely, so that it is easily degraded when folded at a bending angle. Also, due to its flexibility, a flexible LCD cannot keep its shape constant. Therefore, in order to realize a foldable display using a flexible LCD, it is necessary to adjust the “bending rate” and create “tension in both the vertical and horizontal directions” in the flexible LCD itself.
The basic configuration of the casing is the same as that of the first embodiment. As shown in FIG. 1, a plurality of casings 1 are physically connected by a one-axis hinge 2 that rotates about a joint line on the development surface as a center axis. Then, as shown in FIG. 2, the uniaxial hinge 2 may be installed at the end of the casing 1.
Further, in the foldable display using the flexible LCD, the flexible LCD itself is already a continuous device, so that the electrical connection between the casings 1 is unnecessary.
[0017]
Hereinafter, a specific method of adjusting the “bending rate” and securing “tensile force in both the vertical and horizontal directions” in the flexible LCD will be described.
First, in order to adjust the “flexion rate” of the flexible LCD, a flexure adjuster 11 is used as shown in FIG. As shown schematically in FIG. 9, the flexure adjuster 11 is provided with a limit to the “flexibility” while freely changing its shape, and has a gentle curve while preventing the occurrence of a sharp flexion angle. The flexible LCD is foldable.
[0018]
Next, in order to secure “tension in both the vertical and horizontal directions” in the flexible LCD, pillars 13 are attached to the left and right ends of the flexible LCD 12 as shown in FIG. The pillar 13 serves as a strut and a hinge by being inserted into the casing 1 and passing through a shaft. Then, when the casing 1 is unfolded, "tension in both the vertical and horizontal directions" acts on the flexible LCD 12, so that the flexible LCD 12 is in a state of being stretched horizontally. When the casing 1 is folded, the "tension in the horizontal direction" is lost, but the "tension in the vertical direction" continues to work. The flexible LCD 12 is folded inside the casing 1 into a gentle curve by coordinating the rotating function and the above-described bending rate adjustment function of the bending rate adjuster 11.
[0019]
It is considered that the assistance required for the flexible LCD 12 is already sufficient if the functions of the curvature adjuster 11 and the pillar 13 mentioned in the above description are already provided. However, in consideration of the possibility that “slack” and “sway” are more likely to occur as the flexible LCD 12 approaches the center from the left and right ends, not only the “tension in both vertical and horizontal directions” by the pillar 13 but also the flexible LCD 12 It may be more desirable to create an extra "vertical tension" near the center just in case.
As shown in FIG. 8, the securing of the "tension in the vertical direction" near the center of the flexible LCD 12 is achieved by engaging the runner 14 provided on the flexible LCD 12 with the rail 15 provided on the casing 1 and setting the flexible LCD 12 to ""Pull up and down". In addition, the functions of the runner 14 and the rail 15 are not limited to this, and when the flexible LCD 12 is deployed horizontally, the runner 14 is positioned on the development surface side of the casing 1, while the flexible LCD 12 has a gentle curve. When folding the folded state, the runner 14 is provided on the back side of the casing 1 so that the flexible LCD 11 can be delicately moved in accordance with the opening and closing of the casing 1 so as to have a function of "margin" and "play". I have.
[0020]
That is, the flexure adjusters 11 provided above and below the flexible LCD 12 to adjust the “flexibility”, the pillars 13 provided on the left and right of the flexible LCD 12 to create “tension in both the vertical and horizontal directions”, and In order to create extra tension, the runners 14 provided above and below the center of the flexible LCD 12 and the rails 15 provided on the casing 1 complement each other's functions to comprehensively reinforce the flexible LCD 12, so-called "composite tensor". , And prevents the flexible LCD 12 from being inappropriately bent or twisted, regardless of whether the LCD 12 is deployed or folded.
[0021]
At first glance, it seems that the foldable display using the flexible LCD is completed by the above method. However, here, a problem similar to that in the state in FIG. 3 of the first embodiment occurs. That is, there is a problem that the flexible LCD is exposed at the joint surface of the casing when folded, which is unavoidable due to the structure.
Therefore, in order to finally realize the foldable display using the flexible LCD, it is necessary to protect this joint surface, as in the case of the foldable display using the fixed LCD in the first embodiment.
The method of installing the joint surface protection cover on the joint surface is the same as in FIGS. 5 to 7 of the first embodiment, so please refer to that.
Incidentally, in the above description, the LCD is particularly used as the display device. However, an arbitrary display device may be used as needed as long as it is flexible enough to be folded in a curved shape.
[0022]
(Embodiment 3) In this section, a specific example of a foldable keyboard will be described. Note that, as in a usual notebook personal computer or the like, the keyboard referred to here corresponds to the “main body”, and a CPU and the like are appropriately mounted therein.
[0023]
As is well known, there is a custom to secure a "specific arrangement order" and "arrangement intentionally irregular" for keyboard keys in a personal computer or the like. The reason is that if the order of keys is different for each manufacturer or model, the user has to re-learn which character is and where each time the personal computer used changes, and if the key is This is because if the arrangement is not a subtly different arrangement for each column but an orderly arrangement in the vertical and horizontal directions like a grid, the user is more likely to make a mistyping with a higher probability. Therefore, what is desired in any keyboard is that such conventions be met.
[0024]
The foldable keyboard 16 shown in FIG. 10 is designed so that the keyboard can be effectively folded while satisfying the above-mentioned custom in the keyboard. The feature of the foldable keyboard 16 lies in the "regular alternating arrangement" of specific keys along the fold center line 18 among the keys 17.
In other words, as shown in FIG. 10, the "regular alternating arrangement" means that in the vertical odd-numbered rows, the folding center line 18 intersects with the keys, and the right end or left end of the keys is aligned in one vertical row, and the remaining even-numbered rows are arranged. Indicates a state in which the folding center line 18 is located between the keys. In other words, the keys that are in contact with the folding center line 18 are regularly arranged in one row.
[0025]
The basic configuration of the casing is the same as that of the first embodiment. As shown in FIG. 1, a plurality of casings 1 are physically and electrically controlled by a single-axis hinge 2 that rotates about a joint line on the deployment surface as a center axis. To be connected. Further, if the one-axis hinge 2 is installed at the end of the casing 1 as shown in FIG. 2, it is possible to secure a state in which the keys are united as a whole without being divided into independent groups for each casing. .
Further, the key is arranged within the range of the height of the casing so as not to protrude above the deployment surface of the casing, so that folding of the casing is not hindered.
[0026]
When the foldable keyboard 16 thus formed is folded, it is in a state as shown in FIG. In this state, the key 19 is exposed to the outside, but there is no problem since the top surface is eventually covered with the foldable display and the bottom surface is protected by the outer layer of the casing.
But the problem is the side. The key is originally strong against shocks acting vertically to the key tops, but weak against shocks acting laterally. In other words, if the side surface of the key 19 is directly subjected to an external impact from the lateral direction, it cannot withstand carrying.
Therefore, following the first and second embodiments, what is indispensable in the foldable keyboard is the joint surface protection cover.
And "regular alternate arrangement" becomes effective only in relation to this joint surface protection cover. That is, as shown in FIG. 11, the "regular alternating arrangement" provides the protrusions of the keys 19 in one vertical line, and furthermore, the protrusions are small, so that the bonding surface protection cover has a large thickness. You do not need to have In other words, although the bonding surface protection cover is indispensable, it is possible to sufficiently avoid a situation in which the total thickness of the foldable display is excessively increased by increasing the thickness more than necessary.
By the way, if the keys are arranged in a conventional way instead of the "alternate alternating arrangement", the protrusions of the keys will be irregular, large and small, and the protrusions will not be small enough. Must have That is, the volume of the entire foldable keyboard increases accordingly.
Of course, if it is acceptable to increase the volume of the foldable keyboard due to the thickened joint protection cover, the conventional key arrangement may be used arbitrarily, but even a small volume is reduced to pursue portability. When trying to do so, it is more desirable to use "regular alternating arrangement".
In addition, the installation method of the joint surface protection cover is the same as that in FIGS.
[0027]
The above is a series of procedures for forming the foldable keyboard.
In addition, the "regular alternating arrangement" of the keys has a feature that the size distribution of other keys not in contact with the folding center line is easily affected. In other words, as shown in FIG. 10, the size of the key varies slightly. However, it depends on the size of the key, how many times the casing is folded, how many times the casing is folded, and where the casing is divided and folded. I want to control it appropriately.
[0028]
(Embodiment 4) In this section, a specific example of a multi-fold electronic device will be described.
[0029]
12 to 14 show a multi-fold electronic device 20 formed by physically and electrically connecting the foldable display of the second embodiment and the foldable keyboard of the third embodiment.
[0030]
Here, if the foldable keyboard is folded in two, only one joint surface protection cover is required in the foldable keyboard. This means that the left and right balance of the "scaffold" is biased. Therefore, in order to secure a “scaffold” required for stable typing, it is desirable that the foldable keyboard 16 is equally folded in three sides as shown in FIG. 14, and the foldable keyboard 16 is folded in three. Therefore, it is desirable that the foldable displays 3 to be connected are also similar to three folds in terms of the overall appearance and the balance of the center of gravity. However, this does not apply if there is any means for appropriately maintaining the balance between the scaffold, the appearance, and the center of gravity in a folding method other than three-fold.
[0031]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0032]
The "elastic hinge unit" changes the distance and operation direction between multiple objects to be connected in various ways by the extension function in addition to the rotation function of the conventional hinge, and breaks the connection of these multiple objects by the contraction function. Creates an "elastic parallel biaxial hinge structure" that keeps it free of friction.
Another advantage is that unlike a simple rubber band, there is no need to connect with an adhesive, so there is no danger of peeling off, and unlike a simple rubber hinge frame, the frictional resistance of the shaft hole is low and the rotation is not hindered. Therefore, there is no need to make room for the shaft hole and keep the connection loose.
In addition, the function remains the same regardless of the size. Especially when designed to be small, the volume added to the connection target can be very small, so emphasis is placed on portability and portability. Ideal for products.
[0033]
"Joint surface protection cover unit" composed of elastic hinge unit and joint surface protection cover,
a) The "joining surface" of each casing at the time of folding is reliably protected.
b) Automatically repositions during deployment and does not impede any continuity of the screen or any conventional arrangement of keys.
c) Upon further folding, it automatically returns to its original position and again protects the "joining surface" of each casing.
d) In addition, these operations are automatically performed in conjunction with opening and closing of each casing, so that an extra operation procedure and power consumption are not required.
Satisfy all of the conditions.
[0034]
Adopting a "composite tensor" consisting of "flexibility adjusters", "pillars", "runners" and "rails" for reinforcement, prevents improper bending when folding and always secures tension in both vertical and horizontal directions. Thus, a flexible substrate LCD can be used for the foldable display, and a series of complete screens can be formed.
[0035]
The "regular alternating arrangement" of the keys along the folding center line allows the keyboard to be folded without hindering the effect of suppressing mistyping and without unnecessarily increasing the volume of the product.
[0036]
The integration of these technologies will result in a "multi-fold electronic device" that has portability, easy-to-read display, and keyboard operability.
[0037]
The present invention is also applicable to other electronic devices or products in fields different from those of the electronic devices.
