Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a folding table convenient for storing when not in use, and more particularly to such a table with a curtain.
[0002]
[Prior art]
A folding table with a curtain is described in, for example, Japanese Patent Application Laid- Open No. 11-155641 filed by the applicant of the present application, and is well known. In this table, the upper end of the curtain plate is pivotally attached to the back surface of the top plate, and the lower end thereof is pivotally attached to the leg through a link rod. When stowed perpendicularly from the plate and the top plate is in a substantially vertical state, it can be changed to a position along the leg.
[0003]
[Problems to be solved by the invention]
The above-described curtain plate mounting structure in the folding table is sufficient to achieve the object, but requires an additional part such as a link rod, resulting in high cost.
[0004]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to ensure the operation of a curtain plate in a folding table with a simple structure having a minimum number of parts.

[0006]
(2) to the lower surface rear portion of the top plate, the upper end of the curtain plate pivotally mounted by a horizontal axis, when the top plate is in a horizontal position of use, is suspended the curtain plate from the top plate lower surface, the When the top plate is folded, the curtain plate has a lower end abutting on the leg pole so that it occupies a position along the leg pole , and a hinge that pivotally attaches the curtain board to the top board. Ru provided stopper means for stopping the rotation of the blade plate in contact with the top plate formed integrally with the curtain plate mounting side.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the folding table (A) of the present invention is capable of rotating a top plate (2) from a horizontal position shown in the figure to a substantially vertical position (see FIG. 5) on a leg (1) with casters. It is attached to.
[0008]
The leg (1) is composed of left and right front limbs (1a) and rear limbs (1b) connected by connecting ridges (3). For mounting the head part to the upper end of the front and rear leg rods (1a) (1b), for example, a known top plate mounting as disclosed in the above-mentioned JP-A- 11-155641 filed by the applicant of the present application A cum turning mechanism (not shown) is provided.
[0009]
On the rear side of the lower surface of the top plate (2), curtain plates (4) are pivotally mounted at two positions on the left and right sides at positions spaced rearward from the rear leg rod (1b). This axial attachment is made by a hinge (5) shown enlarged in FIG.
[0010]
The hinge (5) has a horizontal top plate side mounting piece (7) pivoted by a horizontal shaft (6) and a vertical curtain plate side mounting piece (8), and both mounting pieces (7) ( 8) is urged in a direction close to each other by a coil spring (9) wound around a horizontal axis (6).
The top plate-side mounting piece (7) is composed of a horizontal surface portion (7a) and an inclined surface portion (7b) inclined obliquely downward from one end thereof, and the lower end of the inclined surface portion (7b) and the above-mentioned curtain plate-side mounting piece ( The upper end of 8) is pivotally connected by a horizontal shaft (6).
[0011]
A projecting piece (10) is connected to one side end of the hinge plate (8) of the hinge plate (5), and a side piece that is bent at a right angle forward and extends obliquely upward (to the side end). 10a) and a top plate abutting piece (10b) which is bent at a right angle inward and forms a right angle with the curtain plate side mounting piece (8) is provided at the front end of the side piece (10a). Yes. A round hole (11) is formed in the contact piece (10b), and a contact member (12) made of a relatively soft synthetic resin material is fitted into the round hole (11).
[0012]
Attach the hinge (5) to the horizontal surface (7a) of the top plate side mounting piece (7) with the screw (13) on the back side of the bottom surface of the top plate (2), and attach the curtain plate side mounting piece (8). Attach to the upper part of the curtain plate (4) with screws (14).
[0013]
The state in which the curtain plate (4) is attached in this way is shown in FIGS. The curtain plate (4) is in a position that hangs straight from the upper end pivotally attached to the lower surface of the top plate (2) by the hinge (5).
In this state, the contact member (12) of the top plate contact surface (10a) of the hinge (5) is in contact with the lower surface of the top plate (2), and the coil spring (9) is attached to the curtain plate side. The piece (8) and its protruding piece (10) are biased toward this state.
[0014]
The abutting member (12) of the hinge (5) holds the curtain plate (4) at a substantially right angle with respect to the top plate (2) by contacting the lower surface of the top plate (2). A stopper acts so as not to rotate inside the lower surface of the top plate (2).
[0015]
When the top plate mounting and rotating mechanism is unlocked by a known operation lever (15) and the top plate 2 is rotated to the substantially vertical position shown in FIG. 5, the lower end of the curtain plate (4) It comes into contact with (1b) and slides downward on the rear leg heel (1b). At this time, the lower end of the curtain plate (4) is naturally rotated from the hanging posture to a position along the rear leg rod (1b) against the force of the coil spring (9) of the hinge (5).
[0016]
Further, in this state, the horizontal surface portion (7a) of the top plate side mounting piece (7) of the hinge (5) and the curtain plate side mounting piece (8) are in a substantially parallel positional relationship in front and rear. By making the interval width between them larger than the thickness of the curtain plate (4) by appropriately designing the inclination angle of the inclined surface portion (7b) of the top plate mounting piece (7), the curtain plate (4) One end thereof can be rotated to a position along the leg rod (1b) in a state of being adjacent to the lower surface of the top plate (2) attached to the horizontal surface portion (7a).
[0017]
As shown in FIG. 5, the table in which the top plate (2) and the curtain plate (4) are folded can be stored in a nesting manner, that is, stacked in the front-rear direction, as shown in FIG.
[0018]
【The invention's effect】
According to the first aspect of the present invention, the curtain plate in the folding table can be provided with certainty of operation while having a simple structure with a minimum number of parts.
Even if the table is slightly shaken, the curtains do not rattle and no sound is produced.
[0019]
According to the second aspect of the present invention , not only can the curtain plate in the folding table be provided with a simple operation with the minimum number of parts, but also the shading of the curtain plate can be eliminated. .
