Description

[Detailed description of the invention] [Industrial application field] This invention relates to the improvement of desks such as tables and desks used at home, office, outdoor camping, etc.

[Prior art] This type of conventional desk has a table board of various shapes, such as round and square shapes, and can be extended, folded, assembled,
Depending on the combination or use, there are various types of tabletops with a wider table surface or structures and shapes that are convenient for storage.

By the way, desks are often moved to be used outdoors or in other rooms, and although a desk always requires a chair, conventionally the chair and desk were separated. Therefore, if there are no chairs nearby, you will have to procure one from somewhere, then transport the desk and the chair, which is time-consuming.
Also, when looking at storage when not in use, some chairs and desks are foldable and do not require much space, but the chair and desk are still separate units, so storage space is required for other chairs on the desk. However, considering that it is desirable to have as little storage space as possible, this was a wasteful point. Furthermore, it was impossible to carry it around freely.

[Problems that the invention aims to solve] However, the present invention is a pedestal with a chair that is convenient to move without the hassle of procuring a chair or carrying the chair separately, and also does not take up storage space. The purpose is to provide a built-in portable desk.

[Means for solving the problem] The portable desk with built-in legs and chairs of the present invention has a table board with a hollow structure, a foldable seat board integrally attached to the middle part, and an upper end part of the table board having a hollow structure. A pedestal that is engaged with the table board and can be stepped on freely is housed in the table board so that it can be pulled out.

[Example] A first example of the present invention will be described based on FIGS. 1 to 8.

The portable desk A with a built-in chair and pedestal, which is applied to a desk, has a hollow structure table plate 1, as shown in Fig. 4.
Inside, vertical guide walls 3, 3 extending over the entire length of the L-shaped guide walls 2, 2 from the upper edge to the vertical center thereof are arranged parallel to each other toward the front with a predetermined interval. Partition plates 4, 4 are attached and extended from the horizontal portions of the L-shaped guide walls 2, 2 to the rear edges in the horizontal and longitudinal directions of the central portions, with a rectangular leg hole 5 cut out in the middle of the front edges sandwiched therebetween. The front plate 6 constituting the table plate 1 is arranged in parallel to face each other, and has a gate shape with an opening 6a in the center area. In the figure, 1a is the top deck.

As shown in FIGS. 1 to 3, left and right rear pillars 9,
The upper ends of the left and right rear leg columns 9 and 10 are pivotally supported by left and right pin shafts 11 and 12, respectively, and a span plate 15 extends between left and right elongated holes 13 and 14 that are bored in the axial direction at the lower ends of the left and right rear leg pillars 9 and 10, respectively. A wing nut 18 is screwed onto a protruding screw 17 which is pivotally supported by a support pin 16 and its right end is attached to the center of the right end surface, and the left and right rear leg pillars 9 and 10 are mounted around the left and right pin shafts 11 and 12. When rotated and parallel to the left and right side plates 7 and 8, the span plate 15 is arranged so as to close the opening 6a of the front plate 6 of the table plate 1.
The position and orientation can be adjusted freely.

In addition, the left and right side plates 7 and 8 of the table board 1 have stopper pieces 19 and 20 protruding from positions near their rear ends, respectively, to receive and lock the rear leg columns 9 and 10, and to rotate the pin shafts 11 and 12 around the pin shafts 11 and 12. Semi-circular guide plate 2
Ball receiving holes 23, 24 are recessed across the guide plates 21, 22 and the left and right side plates 7, 8.
As shown in FIG. 5, the left and right rear pillars 9, 10
The protruding behavior is constantly urged by back-up springs 27, 28 inserted into spring holes 25, 26 formed on the inner surface of the upper part, and the protrusion is prevented by pressing plates 31, 32 having small-diameter circular holes 29, 30 in the center. The protruding ends of the restrained balls 33, 34 are inserted to prevent the folded left and right rear leg pillars 9, 10 from shifting.

Furthermore, as shown in FIGS. 1 to 3, the protruding end 39 of the circular seat plate 38, in which the left and right upper ends of the T-shaped support rod 37 are rotatably inserted into a pair of bearing rings 35 and 36 fixed to the left and right sides of the lower surface, is attached to the inclined leg. It is inserted between a pair of brackets 41 and 42 fixed to the intermediate portion of the column 40 and is pivotally supported by a pin shaft 43, and an insertion hole 44 is bored on the lower end slope of the column 40 to connect the T-shaped support column 37. The circular seat plate 38 is set, while the partition plates 4, which are arranged in parallel inside the table plate 1,
A sliding transverse rod 45, whose both ends can be freely fitted and locked between the opposing surfaces of the vertical guide walls 3, 3 of 4 and the vertically upward tip of the L-shaped guide walls 2, 2, is orthogonally attached to the upper end of the pillar 40. The pillars 40 are pulled out and both ends of the sliding horizontal rods 45 are fitted between the vertical guide walls 3, 3 in the table board 1 and the vertically upwardly directed tips of the L-shaped guide walls 2, 2. It is possible to freely lock it or to release the lock and store it in the table board 1 with both ends guided toward the back under the L-shaped guide walls 2, 2.

In the figure, 46 is a cushion material, and 47 is a handle. In addition, in this embodiment, the dimensions of the table board 1 are 80 mm vertically and horizontally.
cm, but the dimensions of the table board 1 can be reduced if the pillars 40 are constructed to be able to slide and expand in the middle, and in that case, the rear pillars supporting the table board 1 in an inclined state in this embodiment 9 and 10 can also be made small in size so that they can be supported vertically, and the overall size can be reduced.

Next, a second embodiment of the present invention will be explained based on FIGS. 9 and 10.

The portable desk B with a built-in chair and pedestal according to the present invention applied to a table differs from the first embodiment in that it is a small table for one person only, whereas it is a large table for a large number of people. That is, inside the table board 1', a plurality of partition plates 4', 4' groups similar to those in the first embodiment are arranged side by side with the directions reversed for each pair, and the pillars 40 and 4' groups described in the first embodiment are arranged side by side. Similarly, a pedestal 40' with a circular seat plate 38' pivotably supported in the middle is housed between each partition plate 4', 4'. In the figure, reference numeral 48 denotes a lid that closes the openings of the front plate 49 and the back plate 50, one end of which is pivotally supported by a locking pin 51, and the other end of which has a U-shaped notch 52 formed near the right end of the front plate 49 and the back plate 50. They are latched onto tightening screws 54 each having a knob 53 formed on its head which is threaded onto the back plate 50.

Further, 55 in the figure is a handle.

[Function] Since the present invention is constructed as described above, first of all, if we look at the portable desk A with a built-in pedestal with a chair, the circular seat plate 3
8 upwards around the pin shaft 43 and into the insertion hole 44.
If the lower end of the T-shaped support rod 37 is pulled out and the circular seat plate 38 is lowered as it is, the circular seat plate 38 and the T-shaped support rod 37 will be folded parallel to each other onto the front leg column 40, as shown by the imaginary lines in FIG. becomes. After that, as shown in the imaginary line in FIG. 6, if the front side of the table board 1 is slightly lifted and the front leg column 40 is pulled down, both ends of the slide horizontal rod 45 will be connected to the vertically upward tip of the L-shaped guide walls 2, 2 and the vertical guide wall. Since the engagement between 3 and 3 is released, if the front leg post 40 is rotated horizontally and pushed into the table board 1, the front leg post 40 is completely accommodated in the table board.

Next, after loosening the wing nut 18 and positioning the bridge plate 15 at the lowest end of the elongated holes 13 and 14, the rear leg columns 9 and 10 are rotated around the left and right pin shafts 11 and 12, and the rear leg columns are rotated. Once the protruding ends of the balls 33, 34 buried inside the upper parts of 9, 10 are fitted into the ball receiving holes 23, 24, retighten the wing nut 18 that was loosened earlier as shown in Figs. 7 and 8. The opening in the front plate 6 of the table board 1 may be closed.

However, since the portable desk A with built-in legs and chairs has a thin box body, it can be carried by holding the handle 47 provided on the back of the table board 1 like a carry-on bag. It is convenient for storage.

On the other hand, if we look at portable desk B with a built-in pedestal with chair, the circular seat plate 38' is parallel to each pedestal 48 and can be completely accommodated in the table board 1', making it convenient for movement and storage. However, since a plurality of pedestals 40 are provided, it can be used by a large number of people, and since the table board 1' can be supported only by each pedestal 40', other legs [the rear pedestal 9 in the first embodiment, 10] is unnecessary,
This has the advantage that the mechanism is simpler than that of the first embodiment. In particular, the second embodiment is suitable for compact storage in a car or the like and for outdoor use in camping.

[Effects] As mentioned above, the proposed portable desk with built-in legs and chairs has a chair stored inside the tabletop, so there is no need to procure a chair or carry the chair separately for transportation. It is hassle-free and convenient, and has excellent practical utility in that it requires less space than conventional folding chairs and tables that are stored separately.
