DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the embodiments shown in FIGS.
FIG. 1 shows a side view of a folding table according to the present invention in which the top plate 1 is leveled and a blindfold panel 2 is raised in front of the top plate 1. FIG. The side of the folded state is shown.
[0010]
In FIG. 1, support columns 4, 4 are erected on the upper surfaces of the left and right legs 3, 3 installed at appropriate intervals, and fixed to the lower surface of the top plate 1 at the tops of the support columns 4, 4. The top plate receiver 5 is pivotally supported by a pin 6 (shown in FIG. 4), and the top plate 1 is rotatable about the pin 6 from a horizontal state to a vertical state with respect to the support column 4.
[0011]
The blind panel 2 is made of a plate material having a width substantially equal to that of the top plate 1.
[0012]
The lower part of the front end of the top plate 1 and the approximately center position in the vertical direction of the blindfold panel 2 are connected by a hinge 7, and the lower end portion of the blindfold panel 2 and the column 4 are connected by a link 8.
[0014]
In the illustrated embodiment, as shown in FIG. 3, the upper end of the hinge member 9 made of one member is bent in a crank shape, and a hinge hole 10 is formed at the upper end of the bent portion 9 a, so that the front end of the top plate 1 is formed. A pin 13 (shown in FIG. 1) is inserted into the hinge hole 12 of the bearing portion 11 fixed to the lower surface and the hinge hole 10 to constitute a rotatable hinge 7, and the base portion of the bent portion 9a. Is formed with an inclined surface 9b so that the front end 1a can be received when the top plate 1 is rotated in a vertical posture. When the top plate 1 is in a horizontal posture, a gap L through which a cable or the like can be inserted is formed between the front end 1a of the top plate 1 and the blindfold panel 2.
[0015]
The lower end of the hinge member 9 extends to a position near the lower end of the blindfold panel 2, and the link 8 is connected to the lower end of the hinge member 9 and the intermediate position in the vertical direction of the column 4.
[0016]
The blind panel 2 preferably has a built-in magnetic shielding material such as an iron plate in order to eliminate the influence of electromagnetic waves on the facing person when an OA device (display) is installed on the top board 1 and used.
[0017]
The undulating structure of the top plate 1 can adopt the same structure as the above-mentioned Japanese Utility Model Laid-Open No. 7-1826. As a precaution, the specific structure will be described. As shown in FIG. 4, a connecting rod 15 for connecting the left and right top plate receivers 5 and 5 is rotatably provided inside the top plate receiver 5. A separate locking hook 16 is fixed inside 15. The locking hook 16 has a groove 17 at one end, and this groove 17 is engaged with either of the locking pins 18 and 19 provided above and below in the vicinity of the pin 6 of the support column 4. . A coil spring 20 is provided around the connecting rod 15 to keep the locking hook 16 engaged with either of the locking pins 18 and 19 at all times.
[0018]
A connecting member 22 is provided between the operating lever 21 and the locking hook 16. Therefore, when the operating lever 21 is rotated in the direction of the arrow, the locking hook 16 resists the coil spring 20 via the connecting member 22. Thus, since it rotates in the direction of the arrow about the connecting rod 15, the groove 17 of the locking hook 16 is disengaged from the locking pin 18 and is brought into a non-engaged state.
[0019]
Thus, in order to fold the top plate 1 in the horizontal posture in the use state of the table to the vertical posture, the operating lever 21 is rotated in the direction of the arrow and the locking pin 18 of the groove 17 of the locking hook 16 is removed. The plate 1 is free to rotate around the pin 6 and is in a vertical position of a two-dot chain line through a one-dot chain line state. In this state, since the groove 17 of the locking hook 16 engages with the locking pin 19, the top plate is fixed at the position 1 'and the operation lever is fixed at the position 21'. In order to change from the vertical posture to the horizontal posture, the reverse operation may be performed.
[0020]
1 and 2, reference numeral 23 is a shelf provided between the columns 4 and 4 for placing outlets, 24 is a caster attached to the lower surface of the leg 3, and one is provided with a brake.
[0021]
When the top plate 1 is set in a horizontal state as described above, the blindfold panel 2 is pulled upward in the vertical position via the hinge member 9 as shown in FIG. 1, and the upper end of the blindfold panel 2 is the front end portion of the top plate 1. Projects upward to form a blindfold. At this time, a gap L is formed between the front end 1a of the top plate 1 and the blindfold panel 2 by the rising of the bent portion 9a of the hinge member 9, and the cable is used when an OA device is placed on the top plate 1 or the like. Can be led to the shelf 23 and the floor through the gap L.
[0022]
When the top plate 1 is rotated in the vertical state, the blindfold panel 2 is also lowered in the vertical posture, and the lower end of the blindfold panel 2 is regulated by the link 8 and finally the upper half of the blindfold panel 2 as shown in FIG. The part is in close contact with the top board 1 and is folded.
[0023]
【The invention's effect】
As described above, according to the present invention, in a conference table or a lecture table, a user can conceal a document or the like on the top plate so that the document cannot be seen by a concealed panel. When used for a viewing table such as the above, since there is a blindfold panel as a partition with the facing person, the work on the table can be concentrated without being aware of the facing person.
[0024]
In addition, since a gap is formed between the front edge of the top plate and the blindfold panel, when an OA device is used on the table, the cable can be routed through the gap and the top plate surface can be processed. Can be used effectively.
[0025]
Further, when the table is not used, when the top plate is folded, the blindfold panel is also stored in close contact with the top plate, so that the space required for storing the table can be reduced.
