It is a thing. The sub-top plate 3 is divided into two parts at the center, one of which is a turning sub-top plate 3a, and the other is a folding sub-top plate 3b which is pivotally attached to each other. When not in use, the sub-top plate 3a is folded. The auxiliary top plate 3b is configured so that it can be stored in the guide device 4 in a superposed state.

As shown in FIGS. 1, 5 and 6, the guide device 4 includes fixed rails 13 and 13 attached to both upper surfaces of the partition plate 8 of the furniture body 1 and both lower surfaces of the main top plate 2. It is composed of movable rails 14 and 14 to be mounted, and intermediate rails 15 and 15 that associate the fixed rail 13 and the movable rail 14 with each other. The fixed rail 13 is slidably related to the lower portion of the outer side surface of the intermediate rail 15, while the movable rail 14 is slidably related to the upper side of the outer side surface of the intermediate rail 15 so that the main top plate 2 can be moved most. In the semi-used state in which the fixed rail 13 and the movable rail 14 are pushed into the furniture main body 1, the fixed rail 13 and the movable rail 14 are located substantially above and below.

The fixed rail 13 has two roller bearings 16 and 16 projecting from the tip and the center of the inner side surface, and from the upper part to the base end of the roller bearing 16 on the inner side and the central part. A continuous guide groove 17 is formed, and a guide plate 18 is projected inwardly and fixed to the lower surface of the central portion of the roller bearing 16 which extends from the lower end to the front end. Restricting bearings 19, 19 are provided so as to abut on the lower inner side surface of the rail 15 and prevent lateral swing and twist of the intermediate rail 15.

The movable rails 14 are fixed on both sides of the lower surface of the main top plate 2 so as to match the distance between the fixed rails 13, 13, and are fixed to the inner side and the base end portion near the joint edge 10. In the central portion, the same two type of roller bearings 22, 22 are provided so as to project. A buffer body 23 is provided on the base end surface of the movable rail 14 so as to cushion the impact when the movable rail 14 is pushed into the furniture body 1.

The intermediate rail 15 has a lower rail groove 24 slidably contacting the roller bearings 16 and 16 of the fixed rail 13 over the entire length of the lower portion of the outer surface, and is located at the upper portion of the outer surface and slightly proximal to the tip. An upper rail groove 25 is formed in sliding contact with the roller bearings 22, 22 of the movable rail 14 from the side to the base end. Further, between the lower rail groove 24 and the upper rail groove 25, a screw hole or a through hole 27 for screwing the guide pin 26 from the inside is provided at the base end portion, and the screw hole or the through hole 27 is formed through the outside of the intermediate rail 15. The tip of the guide pin 26 protruding from the surface is slidable in the guide groove 17. The both side intermediate rails 15 and 15 are integrally formed by laterally installing the connecting members 28 and 28 at the base end portion and the central portion slightly near the tip end side, and at the lower ends of both end portions of both connecting members 28. A notch 29 is formed for the bearing 19 to pass through.

Then, as described above, the fixed rails 13 and 13 are attached to the partition plate 8 of the furniture main body 1, and on the other hand, before the support legs 11 are attached to the main top plate 2, they can be fixed to both sides of the lower surface of the main top plate 2. After inserting the roller bearings 22 and 22 of the movable rails 14 and 14 into the upper rail grooves 25 and 25 of the intermediate rails 15 and 15 from the open end side thereof, the supporting leg 11 is attached, and the intermediate rails 15 and 15 are mounted in that state. The roller bearings 16 and 16 of the fixed rails 13 and 13 are attached to the fixed rails 13 by inserting the roller bearings 16 and 16 of the lower rail grooves 24 and 24 from the base end open end side thereof, and then the guide pins 26 are provided to the inner side of the intermediate rail 15. Then, the tip is positioned in the guide groove 17 of the fixed rail 13 for assembly. In this state, the guide pin 26 is stopped by the terminal end 30 of the guide groove 17, the intermediate rail 15 is prevented from coming off the fixed rail 13, and the roller bearing 22 on the central side of the movable rail 14 is held. Is stopped at the terminal end 31 of the upper rail groove 25, and the movable rail 14 is prevented from coming off from the intermediate rail 15. Sliders 32 are provided at appropriate places between the fixed rail 13 and the intermediate rail 15 and between the movable rail 14 and the intermediate rail 15 so as to smoothly perform the sliding movements thereof without rattling.

In addition, as shown in FIGS. 1, 7 and 8, the sub-top plate 3 is accommodated in the accommodation space 33 surrounded by the intermediate rails 15, 15 and the connecting members 28, 28 provided therebetween. Is mounted so that it can be swung and folded and accommodated. More specifically, the rotating sub-top plate 3a and the folding sub-top plate 3b are capable of changing from a state in which they are flush with each other by a cylindrical hinge 34 to a superposition state in which they are rotated by approximately 180 °. The plate 3a is rotatably pivoted to the inner surfaces of the connecting members 28, 28 opposite to each other by hinges 35, 35 on both sides of the lower surface, while the folding sub-top plate 3b is connected from the middle of folding to the folded stored state. The lower surface of the support rod 36 is mounted on a support rod 36 provided between the members 28, 28. As described above, in the state where the sub-top 3 is completely stored in the accommodation space 33, the main top 2 can pass above the sub-top 3. On the other hand, with the main top plate 2 pulled out to expose the accommodation space 33 between the main top plate 2 and the furniture main body 1, hold the end of the rotating sub top plate 3a of the sub top plate 3 in the stored state. If it is lifted, the rotating sub-top plate 3a rotates about the hinge 35, and at the same time, the folding sub-top plate 3b slides on the support rod 36 to widen the angle with the sub-top plate 3a. When the rotating sub-top plate 3a becomes horizontal, the angle finally becomes 180 ° and the two become flush with each other. At this time, the spacers 37, 37 protruding from the lower surfaces of the rotating sub-top plate 3a and the folding sub-top plate 3b are placed on the upper surfaces of the intermediate rails 15, 15, respectively, and the sub-top plate 3 becomes the main top plate. It is flush with 2.

Further, as shown in FIGS. 9 to 11, a plurality of engaging holes 38, ... Are provided in the joint edge 10 of the main top plate 2, while the joint edge 12 of the auxiliary top plate 3 is engaged with the engagement hole 38. The protrusions 39, which fit into the holes 38, are projected at corresponding positions, and the main top plate 2 and the sub-top plate 3 are flush with each other, and the main top plate 2 is moved to the furniture main body 1 side. As a result, the protrusion 39 is fitted into the engaging hole 38, and the flush state is maintained. Further, in order to prevent the main top plate 2 and the sub-top plate 3 from being separated from each other, a pair of engagement / disengagement devices 40 are attached between appropriate places on the lower surface in the vicinity of the joining edges 10 and 12 of the two.

Therefore, the sub-top plate 3 is pivoted out from the accommodation space 33 to be in a horizontal state, and the protrusion 39 is engaged with the protrusion 39 in a state where the joint edge 12 faces the joint edge 10 of the main top plate 2. The main top plate 2 is slightly moved to the furniture main body 1 side to be fitted into the joint 38 and joined to each other. At this time, when the sub top plate 3 is also moved to the furniture main body 1 side together with the intermediate rail 15, both Engagement cannot be done completely. On the other hand, in the expanded use state in which the auxiliary top plate 3 is connected between the furniture main body 1 and the main top plate 2, there is a risk that the main top plate 2 or the like may unexpectedly move due to stress in the direction of the furniture main body 1. There is. Therefore, in the present invention, both upper end portions of the one side plate 6 are extended upward inward on both sides of the opening 7 to form the control plate 41 also as a blindfold for the unnecessary space of the opening 7, and the auxiliary ceiling. The lower surface on both sides of the plate 3 and the end portion on the furniture main body 1 side, that is, the lower surface on the free end side of the rotating sub-top plate 3a and the end portion on the furniture main body 1 side and the lower end on the free end side of the folding sub-top plate 3b. Therefore, stoppers 42, 42 made of hard rubber or the like are projectingly provided at the end portion on the furniture main body 1 side so as to stop on the outer side surface of the upper end portion of the regulation plate 41. The direction away from the main body 1 of the house is restricted by the relationship between the guide pin 26 and the end 30 of the guide groove 17 and the relationship between the roller bearing 22 and the end 31 of the upper rail groove 25 as described above. However, the movement restriction positions in both directions are slightly different in order to secure the clearance required for the insertion / removal operation of the engagement hole 38 and the projection 39.

Further, in order to change from the extended use state to the full use state or the half use state, it is necessary to store the auxiliary top plate 3 in the accommodation space 33. The work procedure is as follows. First, with the main top plate 2 and the sub-top plate 3 joined, pull out until the roller bearing 22 comes in contact with the end 31 of the upper rail groove 25, and then the sub-top plate 3 of the furniture main body 1. It is positioned outside the top plate 5, and after the engagement / disengagement device 40 is released, the side edge of the sub-top plate 3 is held forcibly and moved toward the furniture main body 1 side. The fitting with the projection 39 is released, and the auxiliary top plate 3 becomes free. Then, when the side of the folding sub-top 3b or the side edge of the turning sub-top 3a is lifted, the turning sub-top 3a rotates, and at the same time, the folding sub-top 3b slides against the support rod 36. It is bent with respect to the rotating sub-top plate 3a, and finally the two are put in a folded and stored state in which they are overlapped. At this time, there is no particular problem when carrying out the above-mentioned operation by holding the rotating sub-top 3a, but when carrying out the above-mentioned operation by holding the folding sub-top 3b, the rotating sub-top 3a At the moment when the center of gravity becomes inward from the pivot point of the hinge 35, the rotating sub-top plate 3a rapidly rotates to the folded storage state due to its own weight, and both the rotating sub-top plate 3a and the folding sub-top plate 3b are rotated. There is a risk that the free end will hit violently and your fingers will be caught between them. Therefore, as shown in FIGS. 1 and 6 to 9, the rotating sub-top plate 3a and the folding sub-top plate 3b are rigid so as to project from the upper surfaces of the end faces of the furniture main body 1 on the free end side. The cushioning members 43, 43 made of rubber or the like are fixed to prevent finger jamming. That is, as shown in FIG. 8, with the cushioning members 43, 43 in contact with each other, a gap 44, which is slightly larger than the thickness of the finger, is formed between the free ends of the rotating sub-top plate 3a and the folding sub-top plate 3b. The protruding height is set so as to be formed.
