Abstract

PROBLEM TO BE SOLVED: To provide an equipment with a favorable structure have a cover that can minimize destruction or damage of a flat display even if an excessive load is applied on the upper surface of the cover at the closing position. SOLUTION: A pair of a first and a second engaging parts to be engaged at the closing position are provided at the right and left ends of the equipment main body 10 and the cover 50. The engaging parts are a combination of short filament protrusions 71 and 72 provided on the cover 50 side and slits 81 provided at corresponding positions on the main body 11 side. The slits 81 have a shape and measurement enough to fit the short filament protrusions 71 and 72. At the closing position, the filament protrusions 71 and 72 are inserted into the slits 81 so that longitudinal displacement of the cover 50 against the equipment main body 10 is strictly prevented. Even if an excessive load is applied onto the top of the cover 50, each engaging part generates a drag toward the inside against a rib that buckles and tries to expand toward the outside. Consequently, such phenomenon that the rib 55 slides down to expand toward the outside and the gap between the upper surface of the equipment main body and the key top is narrowed is avoided to maximum.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device having a lid comprising a main body and a lid having an open position and a closed position with respect to the main body, and more particularly to a lid including a flat display. A notebook with a "clam shell" structure in which the body is hinged so that it can rotate about the rear edge of the main unit.
The present invention relates to a device having a lid, such as a computer. More specifically, the present invention relates to a device having a lid structure capable of maximally preventing breakage or damage of a flat display even when an excessive load is applied to the upper surface of a lid in a closed position.

[0002]

2. Description of the Related Art With the recent technological innovation, various personal computers (PCs) such as a desktop type, a tower type, and a notebook type have been developed and marketed. Among them, the notebook PC is designed and manufactured to be small and light in consideration of a mobile environment, that is, portable and portable use outdoors or at a destination.

[0003] An example of a notebook PC is an "IBM ThinkPad" marketed by IBM Japan, Ltd.
770 "series (" IBM ThinkPad 77
0 "is a trademark of IBM Corporation of the United States. FIG. 4 and FIG.
The opened state and the closed state of the ThinkPad 770 are shown in perspective, respectively. As shown in the drawings, this type of notebook PC generally includes a relatively thick main body 10 and a relatively thin lid 50. Body 1
A pair of substantially cylindrical tongue pieces 11a and 11b are formed integrally with the main body 10 at a substantially rear edge portion of the zero. These tongue pieces 11a and 11b are received by bearings 51a and 51b, respectively, provided at corresponding portions on the lid 50 side.
As a result, the lid 50 is rotatably supported, and can have an open position and a closed position with respect to the main body 10. Such a structure with a lid is also called a “clam shell”, like a shell that opens and closes the mouth.

The main body 10 is a box-shaped structure, and has a CPU
(Central Processing Unit) System board with circuit chips such as memory (also called "planar")
Also, many hardware components such as a hard disk drive (HDD) and other external storage devices, and a battery pack as a main power supply are housed therein. For this reason, the main body 10 is thicker than the lid 50.

[0005] A keyboard unit 20 as an input device of a computer is provided on the upper surface of the main body 10. The keyboard unit 20 includes, for example, “QW
Each key is arranged in an ERTY "format. Furthermore, the key unit is arranged substantially at the center (for example, QWERT).
In a Y-arranged keyboard, a sticking pointing device 30, that is, a "track point" may be implanted at a location surrounded by the G, H, and B keys).

[0006] The track point 30 is a typical example of a pointing device with a built-in keyboard. The track point 30 has a configuration in which the position corresponding to the point of application of the stick is surrounded by each pressure line difference from four directions in front, rear, left and right. For this reason, the tip of the stick (power point)
Is pressed by the user's fingertip, the pressing direction and the pressing force are detected by the respective sensors, and a signal equivalent to the displacement of the mouse ball is generated according to the output of each sensor. Further, two buttons corresponding to the left and right buttons of the mouse are provided in a palm rest portion substantially in front of the keyboard unit 20. Further, as shown in FIG. 4, a third button corresponding to the middle button of the mouse may be provided.

If a pointing device with a built-in keyboard such as TrackPoint 30 is provided,
The user does not need to carry an external pointing device such as a mouse. Further, the track point 30 is said to be suitable for a notebook PC having a relatively narrow footprint because the installation / operation surface can be small. Further, the track point 30 can be operated without speaking the hand from the home position on the keyboard, so that it is particularly convenient when executing software with keyboard input. The details of the track point 30 are disclosed in, for example, US Pat. No. 5,521,596 and US Pat. No. 5,579,033.

On the other hand, the lid 50 has a structure in which the rear cover 52 receives the display 60. At the lower edge of the rear cover 52, as described above, a pair of bearings 51a are provided.
And 51b are provided.

The display 60 is, for example, a TFT (Thin).
Film Trangister) or DSTN (Dual Scan Twist Ne)
This is a liquid crystal display that is formed in a flat shape and adopts the matic) method. The liquid crystal display is generally a unit including a backlight for illuminating the display contents to the front, and a light guide / diffusion sheet for diffusing irradiation light of the backlight over the entire display. The liquid crystal display is considered to be suitable for a portable, battery-powered notebook PC because it is thin and lightweight and consumes less power. However, this type of display 60 is fundamentally vitreous and is therefore brittle, easily damaged and fragile. In particular, recently, the display 60 has lost its rigidity as it is thinner and lighter.

When the user uses the notebook PC, the user places the lid 50 in the open position as shown in FIG. 4 and causes the keyboard unit 20 and the display 60 to appear, so that input operations and output results can be obtained. Display becomes possible.
Conversely, when a notebook PC is not used (for example, PC
In the case where the cover 50 is transported or put in a predetermined storage place), the lid 50 may be placed at the closed position as shown in FIG. In the closed state, the keyboard unit 20 and the display 6
0 is covered by the rear cover 52 of the lid 50, and is protected from external force applied carelessly when not in use. In the closed position, the lid 50 literally acts as a lid.

However, when the user's arm is pressed down from above on the notebook PC in the closed position, as shown in FIG. 6, when the user is seated on the notebook PC, or when a heavy object such as a book is loaded. For example, when the lids 50 are stacked, the cover 50 formed relatively thin cannot bear the load. In such a case, as shown in FIG. 7, the lid 50 bends downward and the substantially central portion sinks toward the main body. As a result of the progress of this phenomenon, the surface of the display 60 may collide with the opposing keytop and may be damaged. The flat display 60 is originally made brittle as described above. Particularly in recent years, the display 60
Has lost its stiffness and is more susceptible to damage due to damage.

The situation is even worse if the keyboard unit 20 has a stick-like pointing device 30, ie, a track point (described above).
Each key top is only elastically supported on its bottom surface by a spring for generating a tactile, so that the key top comes in contact with the display 60 and the key top can escape downward. On the other hand, the track point is made of a hard material and is firmly fixed at its base for pressure detection. The surface of the display 60 that collides with the track point will receive a much greater impact than if it collides with the key top (see FIG. 8).

Conventionally, in order to prevent a collision between the surface of the display 60 and the keyboard side, as shown in FIG.
It has been made to form ribs on the side edges of the zero. As shown, in the closed position of the lid 50, the rib contacts the upper surface of the main body 10 before the display 60. That is, between the surface of the display 60 and the keytop,
A gap corresponding to the height of the rib can be secured.

However, when an excessive load is applied to the upper surface of the lid 50, the ribs cannot buckle and cannot buckle, and the upper surface of the main body 10 faces outward as shown in FIG. The phenomenon of sliding down was observed. The result caused by the rib slipping off the main body 10 is as discussed above with reference to FIGS.

[0027]

An example of a device having a lid structure according to the present invention is a notebook PC. The most widespread type of notebook PC includes a device main body and a lid having an open position and a closed position with respect to the device main body.

The main body of the device is a box-shaped structure, in which main circuit chips and various peripheral devices are housed, and a keyboard unit as an input device is arranged on the upper surface thereof. On the other hand, the lid has a flat display as an output device on a surface concealed at the closed position. Further, the lid is rotatably supported by the main body at a substantially rear edge thereof, and an opening / closing operation on the apparatus main body is permitted.

The apparatus having the lid according to the second to fifth aspects of the present invention includes a lid and a lid on the left and right edges of the apparatus body and the lid.
A pair of first and second engagement portions that engage at the closed position are provided. Each engaging portion may be, for example, a combination of a short linear projection provided on the lid body side and a slit provided on a corresponding portion on the main body side. The slit has a shape and size just to receive the short streak. Alternatively, the linear projection may be provided on the device main body, and the slit may be provided on the lid side.

In the closed position, the linear projection is just inserted into the slit, and each of the first and second engagement portions is engaged.
As a result, lateral displacement of the lid with respect to the device body is strictly suppressed. In this state, even if an excessive load is applied to the upper portion of the lid, each engaging portion generates an inward reaction against the rib that buckles and tries to expand outward. In other words, the phenomenon (see FIG. 10) in which the ribs slide down so as to expand outward and the gap between the top surface of the device main body and the keytop is narrowed (see FIG. 10) is avoided as much as possible.

In a device having a lid according to a sixth aspect of the present invention, a pair of third engaging portions that engage at a closed position are provided at substantially front edges of the device body and the lid. Is provided. The engagement portion may be, for example, a combination of a short linear protrusion provided on the lid body side and a slit provided on a corresponding portion on the main body side. The slit has a shape and size just to receive the short streak. Alternatively, the linear projection may be provided on the device main body, and the slit may be provided on the lid side.

In the closed position, the linear projection is inserted into the slit, and the third engaging portion is engaged. Since the rear of the lid is pivotally supported (that is, fixed) by the device body, the third
, The displacement of the lid with respect to the device body in the front-rear direction is strictly suppressed. Even if an excessive load is applied to the upper portion of the lid in this state, the engaging portion generates an inward reaction against the rib that buckles and tries to expand forward. That is, the phenomenon (see FIG. 10) in which the ribs slide down so as to spread forward and the gap between the top surface of the device main body and the key top is narrowed (see FIG. 10) is maximized as in the case of the first to fourth side surfaces. Be avoided.

According to the present invention, there is data indicating that the limit load of the lid is improved by about 10 kgf as compared with a conventional device having a lid having no engaging portion.

[0034] Still other objects, features and advantages of the present invention are:
It will become apparent from the following more detailed description based on the embodiments of the present invention and the accompanying drawings.

These tongue pieces 11a and 11b are received by bearings 51a and 51b disposed at corresponding portions on the lid 50 side, respectively. As a result, the lid 50 becomes rotatable, and
It can have an open position and a closed position for zero. Such a structure with a lid is also called a “clam shell”, like a shell that opens and closes the mouth.

The main body 10 is a box-shaped structure, and has a CPU
System boards (also called "planar") on which circuit chips such as hardware and memories are mounted, external storage devices such as hard disk drives (HDDs), and battery packs as main power supplies. Contains hardware components. For this reason, the main body 10 is thicker than the lid 50.

On the upper surface of the main body 10, a keyboard unit 20 as an input device of a computer is provided. The keyboard unit 20 includes, for example, “QW
Each key is arranged in an ERTY "format. Furthermore, the key unit is arranged substantially at the center (for example, QWERT).
In a Y-arranged keyboard, a sticking pointing device 30, that is, a "track point" may be implanted at a location surrounded by the G, H, and B keys).

TrackPoint is a typical example of a pointing device with a built-in keyboard (described above).
Since it is not necessary to carry an external pointing device such as a mouse, and the installation / operation surface is small, it is widely applied to notebook PCs. Further, three buttons corresponding to the respective buttons of a mouse are provided in a palm rest portion substantially in front of the keyboard unit 20.

On the other hand, the lid 50 has a structure in which the rear cover 52 receives the display 60. At the lower edge of the rear cover 52, as described above, a pair of bearings 51a are provided.
And 51b are provided.

The display 60 includes a TFT (Thin Film).

c) It is a liquid crystal display formed in a planar shape, employing the method. The liquid crystal display is usually a unit including a backlight for illuminating the display contents to the front, and a light guide / diffusion sheet for diffusing irradiation light of the backlight over the entire display. Since the liquid crystal display is thin and lightweight and consumes less power, it is a portable and battery-powered notebook.
It is said to be suitable for C. However, this type of display 60 is fundamentally vitreous and is therefore brittle, easily damaged and fragile. In particular, recently, the display 60 has lost its rigidity as it is thinner and lighter.

On the left, right and front side edges of the lid 50, ribs 55 are formed so as to surround the display 60. When the lid 50 is folded down on the main body 10, the ribs are provided before the surface of the display 60.
Since it is in contact with the upper surface of the keyboard unit 20, a gap corresponding to the height of the rib can be provided between the surface of the display 60 and the key top of the keyboard unit 20 in the closed state.

Display becomes possible. Conversely, when the notebook PC is not used (for example, when carrying the PC or clearing the PC to a predetermined place),
The lid 50 may be placed at the closed position. In the closed position, the keyboard unit 20 and the display 60 are
And is protected by the external force that is accidentally applied when not in use. In the closed position, the lid 50 literally acts as a lid (described above).

The notebook PC 100 of this embodiment is characterized in that short linear projections 71, 72, 73 are formed on the left, right and front edge portions of the lid 50, and furthermore, the corresponding positions on the upper surface of the main body 10. Include short line projections 71, 72,
The point is that each of the slits 81, 82, 83 into which the 73 can be inserted is recessed. In this embodiment, the short streak projection 7
Each of 1, 72 and 73 is provided at the tip of a rib 55 formed on the side edge. Therefore, the lid 50 is
In the closed state in which the rib 55 has reached the upper surface of the main body 10 while falling down with respect to 0, each short line projection 71, 72, 73 is received by the corresponding slit 81, 82, 83, so that each pair of short projections 71, 82, 83 is received. The projection and the slit fall into an engaged state. In such an engaged state, an action of strictly suppressing displacement in the planar direction is exerted between the lid 50 and the main body 10.

FIG. 2 shows the notebook PC 1 in the closed state.
10 shows a cross-sectional view in the left-right direction when a load is applied from above to 00.

As shown in FIG.
Are inserted into the corresponding slits 81, 82, and as a result, displacement of the lid 50 in the left-right direction with respect to the main body 10 is strictly suppressed.

When an excessive load is applied to the upper portion of the lid 50 in this state, the ribs buckle and attempt to expand outward, but the linear projections 71 and 72 and the slits 81 in the engaged state. , 82 generate inward drag. That is, the phenomenon (see FIG. 10) in which the gap between the upper surface of the device main body and the key top is narrowed by the sliding down of the rib 55 so as to spread outward is avoided to the utmost.

In this case, therefore, the painful phenomenon described in [Prior Art] with reference to FIG. 10 will be avoided to the utmost.

FIG. 3 is a cross-sectional view in the front-rear direction when a load is applied from above to the notebook PC 100 in the closed state.

As shown in the figure, the linear projection 73 located in front of the lid 50 is inserted into the slit 83. On the other hand, the rear of the lid 50 is prohibited from being displaced rearward as a result of being pivotally supported by the main body 10. Therefore, the engagement of the linear projections 73 with the slits 83 strictly suppresses the displacement of the lid 50 with respect to the main body 10 in the front-rear direction.

When an excessive load is applied to the upper part of the lid 50 in this state, the rib 55 buckles and tries to expand forward. 83 generates a rearward drag. That is,
The phenomenon that the rib 55 slides down so as to spread forward and the gap between the top surface of the device main body and the key top is narrowed (see FIG. 10) is avoided to the utmost.

Therefore, the painful phenomena described in [Prior Art] with reference to FIG. 10 will be avoided as much as in the case of FIG.

[0054] Supplement above with reference to specific embodiments, the present invention has been described in detail. However, it is obvious that those skilled in the art can modify or substitute the embodiment without departing from the spirit of the present invention. That is, the present invention has been disclosed by way of example, and should not be construed as limiting.
In order to determine the gist of the present invention, the claims described at the beginning should be considered.
