It is a connected one.

[Action]

If the front edge of the top plate is manually pulled up and opened, the mounting table rises together with the display. At this time, since the upper roller and the lower roller provided on the mounting table are guided and guided by the guide rails provided in the storage chamber, the mounting table is held horizontally. Alternatively, when the mounting table is raised, the guided portion is guided and raised by the guide rails, and the hinge that pivotally connects the mounting frame and the lifting unit, and the guided portion,
The mounting table is held horizontally.

Further, since the elevating unit is guided and guided by the guide rod while being pulled upward with a predetermined force by the constant tension spring, the force for pulling up the top plate portion may be small.

When the lower roller reaches the opening of the guide rail, the lower roller emerges from the opening onto the front lower roller support piece. As a result, the mounting table gradually inclines forward and upward. Alternatively, when the guided portion reaches the tilt guide portion of the guide rail, the guided portion moves diagonally forward, so that the mounting table swings about the hinge axis and tilts forwardly upward.

Then, when the front edge of the mounting table reaches the upper opening of the storage chamber, the mounting table stops in the inclined posture. At this time,
The top plate portion is opened in a state of being bent into a substantially inverted L shape, and the upper surface and the back surface of the display are covered. On the contrary, when the top plate is pushed down by a person's hand, the mounting table returns to the horizontal state and further descends in the horizontal state, and the mounting table and the display are stored in the storage vacant chamber.

Further, a locking piece 24 is provided on the front end of the top plate 3 so as to project therefrom. Reference numeral 4 is a mounting table on which a computer device having a display is mounted. A link 5 for supporting the left and right side edges of the mounting table 4 and the left and right side edges of the front half portion 41 of the top plate portion 3 so that the top plate portion 3 is bent in a substantially inverted L shape at the elevated position of the mounting base 4. Consolidate at 5. An angle stopper 26 is provided at the end of the link 5 on the mounting table 4 side to prevent the link 5 from rotating more than necessary. The angle stopper 26 may be provided at the end on the top plate 3 side. The number of links 5 is two in the same figure, but the number is not limited to this, and may be one or three or more.

Further, upper and lower guided portions 6 are provided on the rear left and right side edges of the mounting table 4, and the guided portions 6 are composed of an upper roller 7 and a lower roller 8. A pair of guide rails 9 and 9 are attached to the rear left and right inner side surfaces of the storage vacant chamber 2, and a front opening 10 through which the lower roller 8 moves in and out is provided above the guide rails 9. Further, a lower roller support piece 40 protruding forward is attached near the lower edge of the opening 10 of the guide rail 9. Then, the guided portion 6 is guided and guided by the guide rail 9. Reference numeral 25 denotes a slide table, and the locking piece 24 of the top plate 3 is locked to the rear edge of the slide table 25.

As shown in FIG. 2, a guide rod 11 is vertically provided on the front surface side of the table body 1. At the front edge of the mounting table 4, a vertical guide rod 11 guides and guides the front edge of the mounting table 4 to the upper opening of the storage chamber 2. To pivot through. Further, the lifting unit 12 is provided with a constant tension spring 13 having one end fixed to the upper end of the table body 1. Lifting unit 12
Includes a constant tension spring 13, a guided mechanism 14 guided and guided by the guide rod 11, and a lock mechanism 15 that prevents the elevating unit 12 from descending. As shown in FIG. 3, the guided mechanism 14 has three driven rollers 16, 16 and 16 rotatably arranged so as to sandwich the guide rod 11, but the number of driven rollers 16 is not limited. It may be four or more. As shown in FIGS. 4 and 5, the lock mechanism 15 is formed in a V shape in which the upper surface 17 and the lower surface 18 are connected at an acute angle, and the lower surface 18 is fixed to the lifting unit 12. Further, the upper surface portion 17 and the lower surface portion 18 are respectively formed with communication hole portions 19 and 20 through which the guide rod 11 is inserted.
The inner diameters of the holes 19 and 20 are formed slightly larger than the outer diameter of the guide rod 11, but in the natural state, since the upper surface portion 17 is inclined, the outer peripheral surface of the guide rod 11 and the upper surface portion are inclined. The inner peripheral edge of the hole portion 19 formed in the hole 17 contacts. Further, the tip of the upper surface portion 17 is bent upward in a J shape and a locking groove 21 is provided, and a hole portion 22 is provided in a lower surface portion 18 vertically below the locking groove 21.
One end of the wire member 23 is locked to the wire 21 and the wire member 23 is inserted into the hole 22. Although not shown, the other end of the linear member 23 is fixed to the slide table 25, and when the slide table 25 is pulled toward you, the linear member 23 is pulled and the outer peripheral surface of the guide rod 11 is pulled. The inner peripheral edge of the hole portion 19 formed in the upper surface portion 17 is separated so that the lock mechanism 15 is released. The constant tension spring 13 is locked by a locking claw (not shown) to prevent the constant tension spring 13 from being paid out.
The locking claws are configured to be disengaged from the constant tension spring 13 when the slide table 25 is pulled toward you. Reference numeral 37 is a buffer spring that absorbs shock when the lifting unit 12 is dropped.

Then, a display, a CPU, etc. are mounted on the mounting table 4, the slide table 25 is slid forward to release the lock mechanism 15, and the table 3 is held by pushing down the mounting table 4. The slide table 25 is stored in the vacant chamber 2 and is slid to the original position to be in the locked state (see FIG. 1). Further, when in use, the slide table 25 is slid toward the front to release the lock mechanism 15 and hold the top plate portion 3 to pull up the mounting table 4. The constant tension spring 13 that was fed at this time
Since the mounting table 4 is pulled up by being wound up, it can be pulled up with little force.
Further, the top plate portion 3 in the horizontal state is pushed up by the link 5 and gradually bent around the hinge 28. Due to the action of the constant tension spring 13, the upward force F acts on the front edge of the mounting table 4, so that the backward force A acts on the upper roller 7 of the guided portion 6 and the forward direction of the lower roller 8. The guided portion 6 is guided and guided by the guide rails 9 while the force B is applied (see FIG. 6). In this way, the mounting table 4 maintains a horizontal state from the lowest position to an appropriate height above. Then, as shown in FIG. 7, the forward force B
When the lower roller 8 which acts on reaches the opening 10 of the guide rail 9, the lower roller 8 comes out from the opening 10 onto the lower roller support piece 40. As a result, the mounting fourth swings around the upper roller 7 and the hinge 29 and tilts forward in an upward slope.
After that, the front end portion of the top plate portion 3 stops at a position where it has risen to the upper opening portion of the storage empty space portion 2. As a result, the display projects almost completely upward from the storage space 2 and
The display screen is diagonally upward and upward. Therefore,
The operator can easily see the screen. Further, at this time, the link 5 is supported by the angle stopper 26, and the top plate portion 3 is bent in a substantially inverted L shape with the rear half portion 42 being vertical and the front half portion 41 being horizontal or slightly inclined. Therefore, the rear portion of the display on the mounting table 4 does not contact the rear half 42 of the top plate 3. Therefore, the rear end portion of the display can be positioned near the rear end portion of the mounting table 4, and the width dimension of the storage empty chamber portion 2 in the front-rear direction can be set small. Then, the slide table 25 is returned to the original state and brought into the locked state again. At this time, since the constant tension spring 13 is locked by the locking claw, it does not move out, but if the locking claw comes off and the mounting table is about to fall, the constant tension spring 13 will be stuck on the upper surface 17 of the lock mechanism 15. Since the hole portion 19 that has been punched acts so as to press against the guide rod 11 due to the weight of the mounting table 4, the mounting table 4 does not drop (see FIG. 5).

FIG. 8 shows another embodiment. In this embodiment, the guide rod 11 is provided on the rear surface side of the table body 1 and, like the embodiment shown in FIG. Also, an elevating unit 12 including a guided mechanism 14 and a lock mechanism 15 (not shown) is guided and guided by the guide rod 11.

Then, the mounting table 4 described above is mounted on the mounting frame 30 provided with the upright pieces 31.
The rear edge portion is fixed, and the guided portion 32 is provided on the left and right side edges of the lower end of the rising piece portion 31. Further, a pair of guide rails 34, each of which is guided by the guided portion 32 and provided with an inclined guiding portion 33 whose upper end is curved forward, are attached to the rear left and right inner side surfaces of the storage space 2. Furthermore, on the upper end of the standing piece 31 of the mounting frame 30,
It is guided and guided by the vertical guide rod 11 and the mounting table 4
An elevating unit 12 whose front edge is lifted to the upper opening of the storage chamber 2 is pivotally mounted via a hinge 36.

The method of use of this embodiment is the same as that of the embodiment shown in FIG. 1, but as shown in FIG. 9, the guided portion 32 is guided and guided by the inclined guiding portion 33 of the guide rail 34. The mounting table 4 is rotated about the hinge 36 to be inclined.

It should be noted that the present invention is not limited to the above-described embodiments, and design changes can be freely made without departing from the gist of the present invention. For example, although two constant tension springs 13 are provided in this embodiment, the number of constant tension springs 13 may be one or two or more. Further, two guide rods 11 are provided, and one or more constant tension springs are provided between them.
13 may be provided. Further, the other end of the linear member 23 attached to the lock mechanism 15 may be linked to a pedal switch (not shown) installed on the floor so that the lock mechanism 15 can be operated by the foot.
