Description

[Detailed Description of the Invention] (Purpose of the Invention) This invention relates to a furniture-like kotatsu table that can be used by removably attaching an old-style kotatsu board to the lower surface of the center of the table.

(Prior art) As high-value-added furniture-style electric kotatsu, which are modified models of electric kotatsu, which have traditionally been used as household appliances, are now on the market, we have developed an old-style kotatsu board that can be used functionally. A practical kotatsu/seat table that can be used as a trendy seat table and eliminates the waste of purchasing a new one is becoming a consumer need.

(Structure and function of the invention) This invention is a furniture-like kotatsu table that can be used by removably attaching an old kotatsu board with the legs removed to the bottom of the center of the table, in response to the above-mentioned needs. Its basic configuration is a desk with a removable table attached to a frame, a longitudinal curtain in the center of the frame, and a pair of opposing vertical bars that can form a square enclosure on the inside of the curtain. The kotatsu is inserted into the drilled long guide groove so that the width can be adjusted freely, and protruding locking pieces that can removably lock the outer frame of the kotatsu board are provided on the opposing inner sides of the vertical bars. It can be attached to the frame regardless of the size of the kotatsu board according to the outer frame size of the board.

Examples thereof will be described below based on the drawings.

In Figures 1 to 6, the kotatsu/seat table 1
In this case, an old-style kotatsu board K with the legs of a household electric kotatsu removed is attached to the center of the frame 2 shown in Fig. 1 between the longitudinal curtain board 3 and the opposing vertical crosspiece 4 that can form a square enclosure. The removable table 5 shown in FIG.
is placed on a frame body 2, and a hinge screw 7 is screwed into a female threaded cylinder 6 to attach it. As shown in Fig. 3, a locking piece 8 that can removably lock the outer frame F of the kotatsu board to the opposing inner side of the vertical crosspiece 4, which can be freely moved in width in order to attach the old kotatsu board K when viewed from the bottom.
The old-style kotatsu board K is attached to the center of the frame 2. An internally threaded tube 6 is embedded in the tabletop 5 through a mounting hole 12 drilled in the left and right fixing plates 11 that connect the left and right curtain plates 9 and the left and right fixed vertical bars 10 inserted inside them at the center. The table 5 is fixed on the frame 2 by a hinge screw 7 screwed into the frame 2.

The legs 14 are attached to the frame 2 by hinge screws 7 provided on the connecting plates 13 that connect the curtain plates of the frame 2 at their four corners. As shown in FIG. 4, the movable vertical bar 4 inserted inside the fixed vertical bar 10
As shown in FIGS. 5 and 6, the stepped locking portions 15 provided at both ends are loosely inserted into the guide grooves 16 formed on the inner surface of the longitudinal curtain plate 3, so that the left and right vertical bars 4 can be freely moved inward. The two L-shaped locking pieces 8 are screwed into the opposing inner sides of the vertical crosspiece 4 to lock the outer frame F of the old-style kotatsu board K. can be attached to the lower surface of the center of the table as shown in Figure 4.

The effect of this idea is that when using the kotatsu as a kotatsu, the old kotatsu board K can be used with the table 5 removed.
A kotatsu futon is used to cover the frame 2 which is fixed in the center, and during the off-season, the old kotatsu board K is removed and a table 5 is attached to the frame 2 with hinges 7 to be used as a seat. be able to.

(Effects of the invention) Since this invention has the above-mentioned configuration, there is no need to replace it with a furniture-style electric kotatsu, and it can be installed using the old kotatsu board regardless of the size of the kotatsu.It can also be removed during the off-season. The practicality of being able to use it all year round as a table and the low cost of using a kotatsu board make it ideal for the needs of consumers, and the effects of its use are great.
