Description

HEAD ADJUSTABLE LAUNDRY BASKET < RTI ID = 0.0 >

The present invention can arbitrarily adjust the height of the laundry basket, thereby improving the convenience of the user not having to bend the waist when handling laundry, and thus it is possible to carry out overloading to improve handling management efficiency. Even when the laundry basket is formed of a lightweight material, The present invention relates to a laundry basket capable of adjusting the height and height of the laundry basket so that the lifting operation of the laundry basket can be performed stably and smoothly and safety and appearance merchandise are improved.

Generally, in order to put laundry in a laundry basket on a clothes rack, it is inconvenient to repeatedly bend and unfold the waist. Especially, it is difficult for the elderly person or the weak waist to put on the back.

In order to solve such a problem, a technique in which a height adjustment function is given to a laundry basket is disclosed in Korean Patent Laid-Open No. 10-2014-0003293 (published on Apr. 201, 09, hereinafter referred to as "Prior Art 1") and Korean Patent Laid- -0065219 (disclosed in "Prior Art 2", published on May 29, 2014).

In the prior art 1, an inner basket (hereinafter referred to as "laundry basket") is provided in an outer basket (hereinafter referred to as "support portion"), a laundry basket is supported on a height adjustment post, So that the laundry basket is raised.

In the prior art 2, a laundry basket (hereinafter referred to as "laundry basket") is supported such that it can be inserted into and withdrawn from a support portion having an inner space, support portions are supported on four corners, Teeth are provided at four corners, and the handle of the laundry basket is provided with an operating portion for engaging and disengaging the moving teeth and the supporting teeth.

In the above prior arts 1 and 2, the shape of the laundry basket has a mutual male and female coupling structure with the inner space of the supporting part, so that the laundry basket is formed in a square basket shape in which the front, back, left and right sides are vertical.

When the laundry baskets are formed in the form of a vertically vertically rectangular square basket, it is impossible to carry out the superimposed loading, so that one laundry basket occupies one full height space during storage and transportation.

In general, baskets have a large upper part with an entrance, a lower part with a bottom surface, and a sloping upper and lower side with a slope, which enables superimposed loading.

In other words, in the case of the superstructure, the loading space of one basket can be made only a part of the height of the basket according to the inclination from the lowermost position at the time of loading, thereby reducing space occupation during storage and transportation and making handling management easier.

However, as described above, in the prior art, the laundry basket must be formed in a vertically-shaped square support structure and a male-and-female coupling structure, so that the laundry basket must also be formed as a vertical rectangular basket so that overlaying is impossible, There is a fatal problem that occupies and significantly reduces the handling efficiency.

In addition, since the supporting part is also formed in a vertical square structure, it is impossible to superimpose the product so that the laundry basket has the same problem as the laundry basket.

In the prior art 1, since the lifting operation of the laundry basket pushes the footrest of the height adjusting post, the center of gravity of the bottom of the laundry should be positioned below to support the laundry basket during the footrest pressing operation. There is a problem that it is difficult to be put to practical use such as the weight member being below the support.

Further, in the case of the prior art 2, since the movable jaws formed in the laundry basket are engaged with the four corners of the supporting portion in the form of a vertically rectangular basket, when the laundry basket is moved up and down, The horizontal and vertical directions must be balanced at the same time and precisely so that it is difficult for the general user to operate it correctly.

For example, when the laundry basket is tilted at a slight angle at either side, twisting occurs, which makes the elevating operation impossible and failure.

Also, in the prior art 2, when the laundry basket is lifted in a state where the laundry basket is inserted into the inner space of the support portion, there is a problem that the support portion is heard as long as the bottom of the support portion does not become a substantial weight material.

In addition, the prior art 2 has a disadvantage in that, when the vertically installed support teeth are exposed to the outside, there is a danger of being hurt when the child approaches, and the appearance is threatened and the merchantability is deteriorated.

Due to various problems as described above, the technique of the laundry basket capable of adjusting the height of the prior arts has not been put into practical use.

The cover (60) may be formed on the pedestal (20).

The laundry basket A may be formed with a cover A11 in the form of a sleeve for covering the slot 23 of the pedestal.

The sleeve-like cover A11 may be formed in a male-female coupling relationship with the pedestal 20.

The pedestal 20 has a side wall 21 on which a long hole is formed, and the side wall 21 can be formed to form an internal space for accommodating the link unit 10 in a folded state.

Accordingly, the side wall 21 of the pedestal can be formed extending downwardly of the long hole 23 to a predetermined length.

In addition, the pedestal 20 is provided with an upper plate (not shown), and the laundry basket A is fixed to the upper plate or the side wall of the pedestal 20 by using a separate fastening member (not shown).

The laundry basket A may be formed in a variety of sizes and designs such as a circular or elliptical basket shape irrespective of the shape of the pedestal 20 as well as the square basket shape shown in FIG.

9, in the link unit folded state, the outer shape of the laundry basket A, the pedestal 20, and the casing 40 may be in the form of a light wall, as shown in FIG. 9 .

In other words, since the front, rear, left, and right sides of the series of external lines connecting the laundry basket A, the pedestal 20, and the casing 40 have inclination X °, Enables loading.

Further, one or more spacers 17 may be provided between the pair of link units 10 to maintain mutual spacing.

The operation state of the laundry basket 1 having the above-described configuration and capable of adjusting the height according to the present invention will be described below.

The laundry basket A is supported by a pedestal 20 located at the upper end of the link unit 10, and the laundry basket A is lifted and lowered by the folding and unfolding operation of the link unit 10, (Not shown) of the washing basin A and the shape and dimensions of the laundry baskets A can be freely formed from the elevating structure.

Therefore, the basket having the above-mentioned merits can be adopted as the laundry basket, thereby making it possible to significantly improve the space utilization and handling efficiency of the basket when storing and transporting the basket.

In addition, when the outer shape of the laundry basket (A), the pedestal (20), and the casing (40) is formed in a shape of a light beam in the folded state of the link unit, It is possible to improve space utilization and handling efficiency during storage and transportation.

In addition, various shapes and sizes of the laundry baskets A are free from the lifting structure, so that a variety of materials including a soft material can be used as the material of the basket A, as well as a general hard material as well as a soft material which is prevented from cracking or cracking.

The rack gear R of the operating portion 30 which drives the elevating and lowering of the laundry basket allows movement of the lower movable pin 13b only in the vertical spreading direction of the X-shaped link unit 10, The lower movable pin 13b is caught between the teeth of the rack gear by the gravity on which the laundry basket is placed and is prevented from moving.

The link unit 10 in the folded state (see Fig. 4) pulls up the laundry basket A fixed to the pedestal 20 while the user steps on the bottom surface 43 of the casing, The link unit 10 is unfolded in the vertical direction as the upper movable pin 13b is guided by the slot 23 of the pedestal and horizontally moved while being horizontally moved on the gear R (see Figs. 1 to 3) .

Thus, when the pedestal 20 and the laundry basket A are raised and the operation is stopped at any position until the raising is completed, the lower moving pin 13b is caught by the teeth of the rack gear due to the gravity of the laundry basket or the like, And the height of the laundry basket is determined.

At this time, the resilient piece 331 or pusher 335 of the link restraining means presses the lower movable pin 13b to prevent the lower movable pin from being detached from the teeth of the rack gear, and firmly maintains the fixed state .

When the height of the laundry basket A is to be lowered, if the user presses the lever 35 on the lever 35 through the operation passage 45 formed in the casing 40, the lifting portion 3512 The lower movable pin 13b is pushed up while tilting around the hinge pin 355 so that the lower movable pin 13b can be freely moved in the folding direction from the rack gear R. [

Thus, the link unit 10 is folded and the laundry basket is lowered by pressing the laundry basket slightly while the pressing unit 3515 is depressed.

The laundry basket is adjustable in height according to the present invention. When the user pushes the casing 40, a fixed state is maintained when the laundry basket is lifted. When the casing 40 is not made of a heavy material, It is possible to stably perform the lifting operation of the laundry basket.

Further, since the elevating operation of the laundry basket A is performed by horizontally moving the lower movable pin 13b on the rack gear, even when the user does not make an accurate balance in the horizontal and vertical directions when raising the laundry basket A, The folding and unfolding operation of the unit 10 is not affected, so that the lifting and lowering operation can be performed smoothly and there is no fear of occurrence of failure.

1, 7, 8 and so on, the present invention improves safety and design quality by blocking external exposures of link units, rack gears, and the like as described below.

First, the cover A11 in the form of a sleeve is provided under the laundry basket A to prevent the elongated hole 23 formed in the pedestal 20 and the upper pins of the link unit 10 fitted in the long hole from being exposed,

Second, the pedestal 20 blocks the exposure of the link unit by forming a space for accommodating the link unit 10 in the folded state by using the side wall 21,

Third, the top cover 61 and the side cover 63 are provided in the casing 40 to completely block the exposure of the operating portion including the teeth, thereby improving the safety and improving the appearance.

With this configuration, the height of the laundry basket is raised so that only the link unit is visible (see FIG. 7), and the structure of the platform is not apparent at the time of the downward folding so that the safety of the product and the design quality of the product are remarkably improved 8).

As described above, according to the present invention, the height of the laundry basket can be adjusted arbitrarily, thereby improving the convenience of the user. The basket can be adopted as a laundry basket, Since the outer shape of the product in the folded state can have a slope in the form of a vertical axis, it is possible to remarkably improve space utilization and handling efficiency during storage and transportation, and even when the platform is formed of a lightweight material such as aluminum or resin material, So that the lifting and lowering operation can be smoothly carried out by the lifting and lowering of the laundry baskets by using the X-link unit, and convenience in which there is no fear of failure can be ensured, and the design and material of the laundry basket can be freely It can form various consumer's symbol And the external appearance of the link unit and the operation unit is blocked to improve the appearance of the product.

While the present invention has been described with reference to the particular embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
