According to FIG. 4, the length b of the female screw 22 formed on the inner wall of the inner case 2 is longer than a length a of the male screw 32 formed on the outer wall of the projection means 3. .

This is for the end of the female screw 22 to be in close contact with the inner wall of the means 3 and the variable shaft 4 when the female screw 22 and the male screw 32 are coupled to each other, the end of the female screw 22 When the state in close contact with the inner wall of the means 3 and the variable shaft 4 is maintained, the support shaft of the present invention is suppressed since the variable shaft 4 is prevented from flowing in the left and right directions by a gap between the means 3 and the inner case 2. The effect is to support the kitchen furniture safely without shaking.

5 is a cross-sectional view showing a sliding means of the support for variable length kitchen furniture according to the present invention.

The closing cap 7 is formed in the shape of a container with an upper surface open, a hole is formed in the center to form a rotating shaft 72 extending upwards, the end of the closing cap 7 is bent outward to the locking groove portion Since the stepped portion 74 is formed to be inserted into the 54, when the closing cap 7 is inserted from the lower side of the rotating means 5, the stepped portion 74 is caught while the rotating means 5 and the closing cap 7 are deformed by a certain amount. Since the insertion cap is inserted into the groove portion 54, the closing cap 7 is coupled to the rotation means 5 so as to be idling.

Of course, the diameter formed by the stepped 74 is formed to be smaller than the diameter formed by the inner wall of the engaging groove 54, a predetermined amount smaller, so that the finishing cap 7 is idling the inner side of the rotating means (5) Is fastened to.

And, since the length of the closing cap 7 is formed relatively long compared to the handle portion 52 of the rotating means 5 when the closing cap 7 is inserted into the rotating means (5) of the handle portion 52 It is formed to protrude a certain amount to the lower end so that the rotating means (5) is disposed away from the ground by a certain amount.

As a result, when the handle 52 is rotated to adjust the length of the support after the support is installed, the variable shaft 4 is rotated while the variable shaft 4 and the inlet means 3 are rotated inside and outside of the support body 1. As the length of the support is adjusted to go out, the closing cap (7) can be prevented from being rubbed with the ground because the rotating means (5) is idling in the interior of the rotating means (5).

In addition, the closing cap (7), the fixed shaft (9) formed of a synthetic resin material is inserted into the rotating shaft 72, the fixed shaft (9) protrudes to the bottom surface of the closing cap (7) the closing cap ( 7) and the ground to be in close contact, so that when the rotary means 5 is rotated to maintain the close cap 7 in close contact with the ground so that the idling of the closing cap (7) can be induced.

In addition, since the fixed shaft 9 is made of synthetic resin such as rubber, the support main body 1 can be prevented from sliding from the ground by moisture generated in the kitchen in which the support main body 1 is installed. .

The sliding means 10 is accommodated in the closing cap (7), a plurality of balls (8) made of synthetic resin material, and the washer (6) interposed between the ball (8) and the rotating means (5) By including), when the closing cap 7 is idle in the rotating means 5, the hwasher 6 is rotated by friction with the rotating means 5, while the ball 8 is rotated Since the closing cap 7 is not rotated in contact with the ground, the variable shaft 4 and the rotating means 5 which are rotated allow the length of the support to be adjusted without being in contact with the ground.

Looking at the operation of the variable-length kitchen furniture support according to the present invention configured as described above are as follows.

First, when the user grabs and rotates the handle 52 or rotates the handle 52 using a tool, the variable shaft 4 and the projection means 3 on which the handle 52 is fitted are rotated. In addition, the variable shaft 4 is projected outwardly in and out of the support main body 1 by the screw thread formed in the inlet and outgoing means 3 and the inner case 2. As shown in FIG. The length of the support is shortened when inserted into the main body 1, and the length of the support becomes long when the variable shaft 4 protrudes out of the support main body 1, as shown in FIG. Furniture can be installed.

At this time, the washer (6) is in close contact with the inner wall of the rotating means 5 is rotated with the rotating means (5) and the ball (8) while rotating so that the washer (6) and the closing cap (7) is closed The cap 7 is idling inside the rotating means 5.

As a result, since the rotating means 5 and the variable shaft 4 are rotated in a predetermined amount away from the ground, they are retracted in and out of the support main body 1, thereby preventing wear caused by friction with the ground.

And, since the inner case (2) and the retrieving means (3), the rotating means (5), the ball (8) is made of a synthetic resin material can reduce the material cost, in particular, the ball (8) is a lot of moisture Since it does not corrode in the kitchen, it has the additional effect of not causing rust even after long term use.

In addition, since the length (b) of the female screw 22 is formed to be a predetermined amount (c) longer than the length (a) of the male screw 32, the variable shaft 4 as shown in Figs. The gap between the variable shaft 4 and the inner case 2 is maintained because the end of the female screw 22 is kept in close contact with the outer wall of the projection means 3 and the variable shaft 4 when inserted into the case 2. Since the variable shaft (4) can be suppressed from flowing in the left and right direction, the support has an effect that can safely support the kitchen furniture without shaking.

In addition, the extending member (S) is interposed between the appearance means (3) and the rotation means (5) even if the variable shaft (4) is formed longer the rotational movement of the rotation means (5) is directly transmitted to the appearance means (3) In order to ensure that the first tooth 34 to the bottom of the projection means (3), the second tooth (S1) at the top of the extending member (S), the third tooth (S2) at the bottom of the extension (S), the rotating means A fourth tooth 56 is formed at the upper end of the 5 so that the teeth corresponding to each other mesh with each other.

The variable length kitchen furniture support according to the present invention is configured as described above, the variable shaft is indented while being rotated to the lower end of the support body is installed, by installing a closing cap rotatable at the bottom of the variable shaft, by adjusting the appearance of the variable shaft The kitchen furniture may be installed to be horizontally maintained, and the variable shaft and the ground are not rubbed when the variable shaft is rotated by a user, thereby preventing wear and breakage due to friction between the support and the ground.

In addition, the present invention, by the sliding means is installed between the variable shaft and the closing cap, so that the idling of the closing cap can be made easier to rotate the variable shaft can be made more easily because the height adjustment of the kitchen furniture is made smoothly There is an advantage to this.

In addition, a fixed shaft made of a synthetic resin material is inserted into the center of the closing cap, and the fixed shaft can maintain the close contact between the closing cap and the ground, thereby preventing the closing cap from rotating when the variable shaft is rotated. There is an advantage that can prevent malfunction and breakage of the.

In addition, the present invention, the inner case and screwing means, the rotation means is made of a synthetic resin material that is easy to manufacture, made of a first block and a second block of symmetry, the inner case, Since the structure of the mold required for the production of the haunting means and the rotating means is simple, it is possible to reduce the material cost required for manufacturing the support, and to shorten the time required for the production of the support.

In addition, the ball constituting the sliding means is also made of a synthetic resin material, which prevents corrosion or rust generated by moisture generated in the kitchen, thereby preventing the support from being damaged by corrosion and preventing noise generated when the variable shaft is rotated. There is an advantage to this.

In addition, since the female screw of the inner case is formed in a predetermined amount longer than the male screw of the mounting means, the end of the female screw is kept in close contact with the inner wall of the mounting means and the variable shaft, so that the variable shaft can be prevented from flowing in the horizontal direction. There is an advantage that the support can safely support the kitchen furniture without shaking.

By the above-described effects, the flow of the variable shaft can be suppressed even if a separate jaw portion is not formed at the bottom of the inner case, so that the haunting means and the variable shaft can be completely separated from the inner case, thereby damaging the rotating means and the sliding means. When this occurs, the variable shaft can be easily separated from the inner case, thereby reducing the time and cost of repair work.
