Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to legs for home kotatsu.

[Conventional technology and its problems]

Generally, the legs for a home kotatsu are used by being held perpendicular to the side frame of the kotatsu main body on which the top plate is placed, and when not in use, the legs are , it is removed from the kotatsu side frame and stored. That is, the legs are usually screwed onto the side frame of the kotatsu, and it is troublesome and time-consuming to remove them.

Therefore, an object of the present invention is to provide legs for a home kotatsu that can be easily and quickly displaced from the unfolded state to the folded state and from the folded state to the unfolded state.

[Means for solving problems]

The legs for a home kotatsu of the present invention have connecting rods arranged along a pair of opposing side frames of the kotatsu main body, which has a generally rectangular or square shape overall, and a swinging rod at both ends of the connecting rod. A leg for a home kotatsu that is movably attached with a leg body, the base end of the leg body having:
A connecting member is pivotally mounted to allow swinging, and the legs are made perpendicular to the kotatsu main body by pulling inward and the legs are made parallel to the kotatsu main body by pushing outward. , a tension resilient member is interposed between the connecting member and the fixing member attached to the kotatsu main body, and the connecting member is pulled inward against the resilient force of the resilient member. A locking portion is provided on the back surface of the connecting member to be removably locked to the kotatsu main body from the top side of the kotatsu main body.

[Effect]

Further, the connecting member 17 has a locking portion 25 formed on its back surface 23 side, and a locking piece 27 to which one end of the tensile elastic member 26 is hooked is formed on its front surface 29 side.

That is, the locking portion 25 has a hanging piece 33 on the back surface 23,
34 is provided between the hanging pieces 33 and 34, and the upper end of the connecting piece 24 connecting the side frame 8 and the holding frame 9 fits between the hanging pieces 33 and 34.

A fixing member 28 made of a solid rod-like body is installed between the side frame 8 and the holding frame 9, and the other end of the elastic member 26 is hooked to the fixing member 28.

Therefore, the resilient member 26 is interposed between the connecting member 17 and the fixing member 28 attached to the kotatsu main body 2, and the connecting member 17 is pushed outward by the resilient force of the resilient member 26 ( In other words, it is resiliently biased in the direction of arrow A).

Note that the fixing member 28 is attached to the surface 2 of the connecting member 17.
The connecting member 17 is inserted into long holes 31 provided in the ribs 30 on the side 9, and the connecting member 17 is slidable in the directions of arrows A and B. A slit 32 is provided through the connecting member 17 and is used for escape of the resilient member 26.

As shown in FIGS. 1 and 2, when the locking portion 25 is locked to the connecting piece 24, the base end 35 of the leg 6 moves in the direction of arrow B (that is, inward). The legs 6 are pulled vertically to the kotatsu main body 2, and from this state, lock the connecting member 17 with your finger in the recess 18, lift the connecting member as shown by arrow C, and lock it. When the lock to the kotatsu main body 2 by the portion 25 is released, the base end portion 35 of the leg 6 is pressed in the direction of arrow A (that is, outward) by the elastic urging force of the elastic member 26, and the leg 6 swings inward around the connecting rod 4 and is folded so as to be parallel to the kotatsu main body 2, as shown in FIG. In other words, the pivot shaft 22 swings in the direction of arrow D shown in FIG. 2 around the connecting rod 4.
The tip of the leg 6 swings in the direction of arrow E around the connecting rod 4. Further, from the state shown in FIG.
5 is locked, the pivot shaft 22 swings in the direction of arrow G around the connecting rod 4, and the leg body 6 swings in the direction of arrow F around the connecting rod 4, as shown in FIG. As shown, it is in a vertical state with respect to the kotatsu main body 2. Further, the dimension X between the hanging pieces 33 and 34 is slightly larger than the thickness dimension Y of the connecting piece 24. Further, in the state shown in FIG. 2, the connecting member 17, the resilient member 26, etc. are set so as not to protrude from the upper surface 43 of the kotatsu main body 2. In other words, the connecting member 17 and the elastic member 26 are interposed within the height H of the side frames 3 and 8 so that they do not get in the way when a top plate or the like is placed on the upper surface 43 of the kotatsu main body 2. ing.
36 is another pair of side walls 4 facing each other of the leg body 6
The bent portion 19 of the connecting member 17 is inserted into the leg body 6 through the notch portion 36 provided in the inner side wall 42 of the connecting member 17 .

Therefore, when displacing the state shown in FIG. 3 (folded state) to the state shown in FIG. 2 (unfolded state),
Since it is necessary to pull the connecting member 17 inward (that is, in the direction of arrow B), as shown in FIG. The fingers of one hand are in both concave parts 1.
8 and 18, both operating members 17 and 17 can be operated with one hand, making the operation extremely simple.

In addition, as shown in FIG. 2, in the unfolded state, the connecting members 17, 17 facing each other as shown in the figure.
are set so that they do not come into contact with each other.

According to the home kotatsu legs configured as described above, in order to displace the legs 6 from the unfolded state shown in FIG. 2 to the folded state shown in FIG. 17 must be lifted upward once, and in the state of use (deployed state), unless the connecting member 17 is lifted upward manually, the connecting member 17 will not be lifted upwards, and during use, the connecting member 17 will not be lifted upward. It is safe because the body 6 does not fold.

In addition, a heat generating part 37 is provided at the center of the back surface 23 of the kotatsu main body 2, as shown by the imaginary line in FIG.

Next, FIG. 5 shows another embodiment, in which case,
Two operating mechanisms 7 are provided. That is, the central portions of the side frames 3, 3 are connected by a pair of connecting frames 38, 38, and the above-mentioned operating mechanisms 7, 7 are interposed between the connecting frames 38, 38, and the operating mechanisms 7, 7 are interposed between the connecting frames 38, 38. By operating the kotatsu with one hand, all the legs 6 can be placed vertically or horizontally with respect to the kotatsu main body 2 at the same time.

In this case, the connecting rod 4 is provided with a corner part 39 having a substantially square cross section in the same manner as the corner part 10 provided at the end part 5, and the corner part 39
is inserted through a hollow, substantially cubic connecting body 40. A notch similar to the leg 6 is formed in the connecting body 40, and the connecting member 1 extends from the notch.
The bent portion 19 of No. 7 is inserted into the connecting body 40, and the pivot shaft inserted through the connecting body 40 is inserted into the insertion hole 20 of the bent portion 19. That is, the connecting body 40 has substantially the same shape as the base end portion of the leg body 6.

Therefore, when the connecting member 17 is in a state where the locking portion 25 is locked to the connecting piece 24 as shown in FIG.
The upper end of the upper end of the connecting rod 4 of 0 is pulled inward, the leg body 6 maintains a vertical state with respect to the kotatsu main body 2, and the locking of the connecting piece 24 of the locking part 25 is released. For example, the pivot shaft is the pivot shaft 22 shown in FIG.
Similarly, the legs 6 swing in the direction of the arrow E around the connecting rod 4, and in conjunction with this swing, the legs 6 swing in the direction of the arrow E, as shown in FIG. It becomes parallel to the main body 2. That is, by locking the fingers of one hand in the recesses 18, 18 of the connecting member 17 of both operating mechanisms 7, the legs 6 can be simultaneously folded or placed in a vertical state by operating that one hand. .

Note that the present invention is not limited to the above-mentioned embodiments, and the design may be changed without departing from the gist of the present invention. For example, the overall shape of the kotatsu main body 2 may be made into a substantially rectangular shape, and the legs may be The shape of 6 may be either a cylinder or a rectangular cylinder whose cross section is a polygon other than a quadrangle. Further, in the embodiment shown in FIGS. 1 to 4, four operating mechanisms 7 are provided, but the operating mechanisms 7 disposed along the side frames 8, 8,
It is also possible to omit the operating mechanisms 7, 7 disposed along either one of the side frames 8 of the legs 6, and in this case, as in the embodiment shown in FIG. It is possible to perform the following rocking operations.

[Effect of idea]

Since the present invention is constructed as described above, it produces the following effects.

If the connecting member 17 is pulled inward against the elastic force of the elastic member 26 and the locking portion 25 of the connecting member 17 is locked to the kotatsu main body 2, the legs 6 will move against the kotatsu main body 2. It becomes vertical (that is, unfolded state).

Further, the connecting member 17 is changed from the locked state of the locking portion 25.
If you lift it upward, the locking part 25 will come off from the kotatsu main body 2. If you release the inward tension on the connecting member 17 in this state, the connecting member 17 will come off due to the elastic force of the resilient member 26. As a result, the legs 6 become parallel to the kotatsu main body 2 (that is, in a folded state).

Therefore, the legs can be easily and quickly put into the unfolded state or folded state.

Also, if the legs are folded when not in use,
The entire kotatsu can be made compact and can be placed in the corner of a room or stored in a closet without taking up much space.

In this home kotatsu leg, in order to displace the leg body 6 from the unfolded state to the folded state, the connecting member 17 must be lifted upward once, but the kotatsu body 2 is used in a horizontal state. In this case, the connecting member 17 does not naturally lift upward. That is, during use, the kotatsu main body 2 is usually covered with a kotatsu comforter, and a top plate is placed on top of it, so after removing these top plates, etc., the connecting member 17 is artificially lifted upward. Otherwise, the legs 6 cannot be folded, and it is safe because they will not be folded accidentally.
