 Therefore, in the invention according to claim 1, a supporting leg is pivotally attached to the lower surface of the top plate, and a slide stay is interposed between the supporting leg and the top plate, and one end of the slide stay has the top plate. And the other end is movably linked in a guide groove provided in the support leg, and the other end is held immovably at the lower end position in the guide groove, so that the support leg is While being held in a use position substantially orthogonal to the top plate, it is held immovably at the upper end position in the guide groove so that the supporting leg is held in a folding position along the lower surface of the top plate. In the configured folding table, a groove is provided in the protection member for buffering the folding tables when stacking the folding tables, and the groove is provided at the upper end position of the guide groove. The other end of the slide stay is fitted and held. Wherein the structure and the that.

According to a second aspect of the invention, in the folding table according to the first aspect, the protective member is made of synthetic resin or synthetic rubber, and the other end of the slide stay is held in the groove by elastic fitting. It is characterized in that it is configured as.

Further, the invention according to claim 3 is the folding table according to claim 1, wherein a torsion coil spring is interposed between the slide stay and the top plate, and the other end of the slide stay is The feature is that it is biased toward the lower end position of the guide groove.

[0007]

[Action]

 According to the structure of claim 1, when the supporting leg is rotated between the use position and the folding position, the other end of the slide stay moves in the guide groove, and with this, the slide stay rotates up and down. Move. When the support leg is taken out to a use position almost orthogonal to the top plate, the other end of the slide stay reaches the lower end of the guide groove, and the lower end of this guide groove is formed linearly in the bending direction as usual. Therefore, the other end of the slide stay reaching the same portion is held, and thus the slide stay is held non-rotatably, and thus the supporting leg is held in the use position. On the other hand, if the other end of the slide stay is removed from the lower end of the guide groove, the supporting leg can be rotated in the folding direction, and when the supporting leg is rotated in the folding direction, the other end of the slide stay is moved to the upper end of the guide groove. When the supporting legs are folded toward each other, the other end of the slide stay is fitted into the groove of the protective member and held at this position. Since the other end of the slide stay is held by the upper end of the guide groove, the slide stay cannot rotate, and therefore the supporting leg is held in the folded position. In this way, the groove portion into which the other end of the slide stay is fitted to hold the supporting leg in the folded position is formed in the protective member, and the protective member scratches the top plate surface when stacking the folding tables. It is commonly used in the past to prevent this, and therefore no special member is needed to hold the fulcrum in the folded position.

According to the second aspect of the invention, the other end of the slide stay is elastically fitted and held in the groove of the protection member. By forming this protective member by integral molding of synthetic resin or by making it of synthetic rubber, it is possible to impart appropriate elasticity, so this elasticity allows the other end of the slide stay to be grooved without using any other member. Can be held in the inserted state.

According to the third aspect of the present invention, the slide stay is biased by the torsion coil spring in the direction in which the other end of the slide stay moves to the lower end of the guide groove. Therefore, the support leg receives a light force by this biasing force. Can be moved to the use position. Conversely, when the support leg is folded, the support leg is rotated in the folding direction against the torsion coil spring, and when the other end of the slide stay is fitted in the groove of the protective member, the other end is The torsion coil spring is pressed against the side wall of the groove by the urging force of the coil spring, so that the urging force of this torsion coil acts as a force to hold the other end of the slide stay in the groove, so that the supporting leg is more securely folded. Retained.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 3, frames 2 and 2 are attached to the lower surface of the top plate 1 along the front and rear edges thereof by screws 2a in parallel with each other. Is installed. A bracket 4 having a U-shape is fixed to the upper end of each supporting leg 3 in an inwardly open direction. The bracket 4 and the frame 2 are connected by the support pins 4a with the ends of the frame 2 inserted between both edges of the bracket 4, whereby the support legs 3 center on the support pins 4a and the lower surface of the top plate 1. It is pivotally attached to the. As shown in the drawing, the supporting legs 3 and 3 adjacent to each other in the front and rear are connected by a connecting rod 5 at approximately the middle of each other. Therefore, the supporting legs 3 and 3 are paired and rotatable as a unit, that is, the top plate. 1 is rotatably supported between a use position substantially orthogonal to 1 and a folding position along the lower surface of the top plate 1. The right supporting legs 3 and 3 (not shown) have the same structure and can be folded inward.

A guide groove 6 is formed on the inner edge of each bracket 4. As shown in FIG. 1, the inner groove 6 is formed with an arc portion 6a, a bent portion 6b formed continuously under the arc portion 6a, and an upper portion of the arc portion 6a. It is composed of a straight line portion 6c. The bent tip portion 7a of the slide stay 7 is inserted into the guide groove 6. This bent tip portion 7a corresponds to the other end portion described in the scope of utility model registration. Reference numeral 6d in the drawing denotes a groove provided on the linear portion 6c of the guide groove 6, and this groove portion 6d allows the bent tip portion 7a of the slide stay 7 to be inserted into the guide groove 6 when the folding table is assembled. It is provided for smooth insertion. With this groove 6d, the slide stay 7 can be easily assembled.

As shown in FIG. 3, the slide stay 7 is formed by bending an end portion of a bar member into a U-shape. Similarly, the slide stays 7, 7 which are adjacent to each other in the front and rear are connected by a connecting rod 8 in the middle thereof. The bending base end portions 7b of the respective slide stays 7 are rotatably connected to the inner surface of the frame 2 described above, and therefore the respective slide stays 7 are vertically moved about the respective bending base end portions 7b. It is freely rotatable. Since a torsion coil spring 9 is interposed between the slide stay 7 and the frame 2, each slide stay 7 is biased in a direction to rotate downward. The bent tip portion 7a of the slide stay 7 thus provided reaches the inside of the bent portion 6b of the guide groove 6 when the supporting leg 3 reaches the use position as shown in FIG. The length of the slide stay 7 or the supporting position of the bent base end portion 7b is set so that when the sheet 3 is folded, the straight stay portion 6c of the guide groove 6 is reached.

Next, a protection member 10 manufactured by integral molding of synthetic resin is attached to the upper end of each bracket 4. This protective member 10 is a member which is conventionally attached to the same portion in order to prevent the top plate surface from being scratched when a plurality of folding tables are stacked, and the protective member 10 is modified. In this example, as shown in FIG. 4, the outer edge 10a, the middle edge 10b, and the inner edge 10c are formed into a substantially E shape, and the bottom edge upper end portion of the bracket 4 is sandwiched between the outer edge 10a and the middle edge 10b. It is attached to the upper part of the bracket 4. For this reason, as shown in the drawing, the outer edge 10a is positioned on the outer surface of the bottom edge of the bracket 4 so that the outer edge 10a is stacked on the outer surface of the bracket 4, so that the outer edge 10a is stacked as a cushioning member when stacked. It comes in contact with the surface.

A groove portion 10d into which the bent tip portion 7a of the slide stay 7 can be inserted is formed between the middle edge 10b and the inner edge 10c of the protective member 10. The groove portion 10d is It is aligned with the straight line portion 6c of the guide groove 6, and therefore, when the supporting leg 3 is folded and the bent tip end portion 7a of the slide stay 7 reaches the straight line portion 6c of the guide groove 6, substantially at the same time. The tip portion 7a is adapted to be inserted into the groove portion 10d of the protection member 10. Here, since the inner edge 10c is elastically biased in the direction of closing the groove 10d, the bent tip portion 7a of the slide stay 7 is inserted into the groove 10d while expanding the inner edge 10c, and after being inserted, The elastic force of the inner edge 10c holds it in the groove 10d.

According to the folding table of this example configured as described above, when the supporting legs 3 to 3 are rotated between the use position shown in FIG. 1 and the folding position shown in FIG. As a result, each slide stay 7 is vertically rotated about the bending base end portion 7b, so that the bending tip end portion 7a moves in the guide groove 6. That is, as shown in FIG. 1, when the supporting leg 3 reaches the use position, the slide stay 7 is pivoted downward, and the bent tip end portion 7a thereof reaches the bent portion 6b of the guide groove 6. In this state, the slide stay 7 is biased downward by the torsion coil spring 9, so that the bent tip end portion 7a is held at the lower end portion of the bent portion 6b, and thus the supporting leg 3 is held at the use position. .

In order to fold the support leg 3 from this state, the slide stay 7 is rotated upward against the torsion coil spring 9, so that the bending tip portion 7a is released from the inside of the bending portion 6b and the inside of the arc portion 6a. Then, the supporting leg 3 is rotated inward. At this stage, the slide stay 7 is rotated upwards against the torsion coil spring 9, so that the bent tip portion 7a thereof moves upward in the arc portion 6a of the guide groove 6 (straight portion 6c). Move.

When the support leg 3 is rotated to a position close to the folding position, the bending tip portion 7a of the slide stay 7 reaches the straight portion 6c of the guide groove 6, and at this point, the bending tip end portion is bent. 7a pushes the inner edge 10c of the protection member 10 and spreads it, and is inserted into the groove 10d of the protection member 10. As shown in FIG. 2, when the support leg 3 is completely folded, the bent tip end portion 7a of the slide stay 7 is completely inserted into the groove portion 10d of the protection member 10, and this state is the protection member. It is held by the elastic force of the inner edge 10c of 10, so that the supporting leg 3 is held in the folded position. Moreover, as is apparent from FIG. 2, since the bent tip portion 7a is pressed against the middle edge 10b of the protective member 10 by the torsion coil spring 9 when inserted into the groove portion 10d of the protective member 10, Also in this respect, the bent tip end portion 7a is held in the groove portion 10d, so that the supporting leg 3 is reliably held at the folding position.

As described above, the holding of the supporting leg 3 in the folded position is achieved by holding the bent tip end portion 7a of the slide stay 7 in the groove portion 10d of the protection member 10. Reference numeral 10 has been conventionally generally attached in order to prevent scratches on the surface of the top plate when stacking the folding tables. From this, according to the folding table of this example, the supporting leg 3 can be reliably held in the folding position without using any special member, and thus the supporting leg 3 can be held in both the use position and the folding position. A folding table that can be securely held can be provided at a lower cost than before.

Although the protective member 10 is made of synthetic resin in this example, the protective member 10 is not limited to this and may be made of synthetic rubber, and the torsion coil spring 9 is not always an essential member. Further, although the support legs 3 and 3 adjacent to each other in the front-rear direction are connected to each other by the connecting rod 5 and integrally rotated, the respective support legs 3 to 3 are independently rotatable and therefore can be folded into pieces. The slide stays 7 to 7 can be independently rotated, that is, the slide stays 7 and 7 that are adjacent to each other in the front and rear direction can be connected to each other by a connecting rod 8 as in this example. The configuration may be such that they are not connected. Further, the protective member 10 is provided with the inner edge 10c for elastically holding the bent tip portion 7a of the slide stay 7, but the leaf spring is insert-molded to replace the inner edge 10c. It is also possible to do so.
