Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a kotatsu device in which the area of the top plate is variable.

[Conventional technology]

Recently, a horigotatsu device has been proposed in which the size of the horigotatsu can be changed depending on the number of people using it. FIG. 7 is an exploded perspective view showing the outline of this horigotatsu device. In Figure 7,
1 is a low table, and this low table 1 has a top plate 2 that can be divided into two in the direction of expansion and contraction, legs 3 attached to the four corners of this top plate 2, and between the top plate 2 that is divided when it is extended. It consists of an auxiliary top plate 4 that is sandwiched. The auxiliary top plate 4 is folded and stored on the back side of the top plate 2 when the low table 1 is retracted, and when the low table 1 is extended, the auxiliary top plate 4 is attached to a pivot shaft (not shown) with the top plate 2 divided into two. It rotates upwards around the center, then unfolds and is sandwiched between the top plates.

An inner stile 1 is provided between the bottom surfaces of a pair of legs 3, 3 that are perpendicular to the expansion and contraction direction of the low table 1 among the legs 3 at the four corners.
0 is bridged.

A low table 1 is placed on the top surface of an outside stile 5. The outer stile 5 is disposed around the periphery of an opening provided on the floor, and the inner stile 10 is slidably placed on the upper surface in response to expansion and contraction of the low table 1. Also,
A secondary stile 6 is fixed to both sides of the upper surface of the outer stile 5, with which the inner surface of the legs 3 comes into contact when the low table 1 is retracted, and a step is created between the stile 5 and the floor surface (tatami surface) outside of the stile 5. It prevents this from happening.

Each side of this sub-stile 6 has dowel holes 7,
7 is provided. This dowel hole 7 is for attaching a spacer 8 to be inserted between the sub-stile 6 and the legs 3 of the low table 1 when the low table 1 is extended. Insert a dowel (not shown).

Further, in FIG. 7, 9 is a cover plate which hides the opening and the outer stile 5 that protrude from the lower table 1 when the lower table 1 is retracted, and is placed on the protruding part of the outer stile 5. placed.

[The problem that the idea aims to solve]

It is necessary to join the auxiliary top plate 4 to the top plate 2 so that the auxiliary top plate 4 does not fall off between the top plates when the low table 1 is extended. For this reason, dowel joining is used in which the divided end faces of the divided top plate 2 and the auxiliary top plate 4 are joined with dowels.

In this case, for dowel joining, a gap is required for inserting the small protrusion of the dowel into the other dowel hole. However, when the low table 1 is extended, the inner stile 10 is located at the edge of the outer stile 5, and the outside is surrounded by flooring, so it cannot be slid further outward, and the dowel joint It was not possible to secure the necessary time.

Therefore, when the table 1 is extended, the inner stile 1
It was proposed to position the stile 0 slightly inward from the edge of the outer stile 5, but it was said that this would cause a space between the inner stile 10 and the outer stile 5 during normal use of the horigotatsu, spoiling the appearance. There was a problem.

Therefore, the purpose of this invention is to provide a horigotatsu device in which an auxiliary top plate can be easily clamped and fixed between divided top plates by dowel jointing, and the appearance of the kotatsu table is not damaged. It is.

[Means to solve the problem]

The horigotatsu device of this invention consists of a top plate that has legs on the underside and can be divided into two parts by dowel joints, and a top plate that is divided into two parts and is interposed between them. an extendable low table having an auxiliary top plate whose surface is dowel-jointed with the split end face of the top plate to expand the area of the top plate; and a pair of legs of the leg portions that are perpendicular to the direction of expansion and contraction of the low table. an inner stile that spans between the bottom surfaces of the parts and fixes these legs; and an outer stile that is placed around an opening provided in the floor and on which the inner stile is placed; It is characterized by being slidably fixed in the extension direction of the low table by a length sufficient to form a gap for dowel connection to the stile.

[Effect]

According to this invention, when a low table is extended and an auxiliary top plate is clamped and fixed between the divided top plates by dowel jointing, the legs of the low table are placed against the inner stile while the low table is extended. Slide the part in the extension direction, that is, along the elongated hole to the outside of the outer stile. As a result, a gap is formed between the divided end faces of the divided top plate and the auxiliary top plate located between them, and a dowel protrudes from one of the facing surfaces of the top plate and the auxiliary top plate. can be made to face the pot hole provided on the other side. By sliding the legs back to their original positions in this state, dowel joining can be easily performed.

For this reason, there is no need to prepare a space for joining the dowel in advance, the appearance of the horigotatsu is improved, and it is no longer noticeable that it is a retractable low table.

〔Example〕

An embodiment of this invention will be explained based on FIGS. 1 to 6. Incidentally, the same constituent members as those of the horigotatsu device shown in FIG. 7 are given the same reference numerals and the explanation thereof will be omitted.

FIGS. 1A and 1B are explanatory diagrams showing the dowel joining procedure of the auxiliary top plate in one embodiment of this invention,
FIG. 2 is a partially enlarged cross-sectional view. As shown in FIG. 1A and FIG. 2A, for dowel joining, a dowel 12 protruding from the split end face of the top plate 2 is inserted into a dowel hole 11 provided on the side surface of the auxiliary top plate 4. The legs 3 of the low table 1 are connected from the top surface of the inner stile 10 to the floor surface 16.
(such as a tatami surface), and then
As shown in Figures B and 2B, the legs are returned to their original positions, the spacers 8 are attached, and the extension of the low table 1 is completed.

In addition, when the dowel hole 11 is provided on one side of the auxiliary top plate 4, a dowel (not shown) is provided protruding from the other side, and this dowel is formed in the dowel hole formed on the divided end face of the top plate. to be inserted into. Therefore, when the low table 1 is retracted, the divided top plates are joined together by dowels. Further, the divided top plates are slidably connected by rails or the like and joined by dowels as described above. This structure is similar to the structure disclosed in, for example, Japanese Unexamined Utility Model Publications No. 60-48831 and No. 60-63239.

A first elongated hole 13 is bored in the top surface of the holder, and a second elongated hole 14, which communicates with this elongated hole 13 and is larger than the elongated hole 13, is bored in the bottom. These elongated holes 13 and 14 are formed so that their longitudinal directions extend along the expansion and contraction direction of the low table 1. Then, a fixture 15 (screw, etc.) is inserted through the second elongated hole 14 at the bottom.
The leg part 3 is slidably fixed to the inner stile 10 along a first elongated hole 13. As shown in FIGS. 5 and 6, the fixture 15 includes a shaft portion 15a (threaded portion) that is inserted through the first elongated hole 13 and whose tip is screwed into the leg portion 3, and this shaft portion 15a. formed at the end of the second
A head 15b accommodated in the elongated hole 14 and locked to the side edge of the first elongated hole 13; and a sleeve 15c that is sheathed on the shaft portion 15a and interposed between the head 15b and the bottom surface of the leg portion 3. It consists of.

When the leg portion 3 is slid from the inner stile 10 to the outer floor surface 16, the fixture 15 is located at one end of the first elongated hole 13, as shown in FIG. On the other hand, in the normal extended state of the low table, the fixture 15 is located on the other end side of the first elongated hole 13, as shown in FIG. Therefore, the first elongated hole 13 prevents the leg portion 3 from sliding excessively, and the dowel joint can be reliably performed.

[Effect of idea]

According to this invention, since the legs are fixed to the inner stile so as to be slidable in the extension direction of the low table, the auxiliary top plate can be easily sandwiched and held between the divided top plates by dowel joining.

Furthermore, since there is no need to secure a space in advance for dowel joining, there is an effect that the appearance will not be spoiled.
