Patent Description:
Recently, a delivery service for delivering articles to a predetermined place has been activated. Particularly, when the article is fresh food, a refrigerator or a heating cabinet is provided in the delivery vehicle to prevent the food from being spoiling or getting cold so that the food is stored and delivered.

It is common that food is generally delivered in packaging to be maintained in a cooled or warm state. The packaging material is made of environmental pollutants such as Styrofoam, thereby creating a social atmosphere to reduce usage.

If the user is at home at the delivery time, the delivery person and the user may face-to-face to receive food, but when the user is not at home or when the delivery time is too early or too late, it is difficult for the delivery person and the user to face-to-face to receive the food.

Therefore, even if the delivery person and the user do not directly face each other, the food may be delivered, and there is a need to not spoil or cool the food until it is finally delivered to the user.

In order to solve this problem, recently, the refrigerator is installed at the entrance (front door) at a predetermined place, so that the delivery person keeps the food in the refrigerator to keep the food in a fresh state, and the user may access the refrigerator at a convenient time to receive the food.

In the prior art below, an entrance refrigerator mounted on an entrance door is disclosed.

Prior Art: <CIT>). <CIT> relates to a deployable pet carrier assembly for a vehicle, comprising: a sliding rail guide system configured to attach the pet carrier to a vehicle seat back; and collapsible front, rear, and side walls defining a carrier structure when deployed. <CIT> relates to a computer case, and more particularly to a computer case which can adjust an inner space of the computer case. <CIT> relates to a tank, and more particularly to a retractable stream tank. <CIT> relates to storage devices for the delivery and pickup of goods, and more particularly to a storage device that secures goods from theft and exposure to the elements and that provides a notification that goods have been delivered to and/or picked up from the storage device.

In the entrance refrigerator disclosed in the prior art, a separate storage box is not provided in a food storage space. That is, the storage box that is capable of being accommodated in or withdrawn from the storage space of the entrance refrigerator is not disclosed.

In addition, most of the storage boxes of the typical refrigerators are single-type storage boxes that are not capable of being adjusted in size. However, since a product ordered by a consumer through an on-line market vary in volume and shape depending on the type thereof, it is required to be able to adjust a size of a storage box to sufficiently accommodate the product.

A storage box for a refrigerator at an entrance according to claim <NUM> is provided to solve the above inconvenient of the prior art storage boxes.

According to the storage box for the entrance refrigerator according to the present invention having the above configuration, the width and height of the storage box may be adjusted according to the size of the ordered product, and thus, the articles having various shapes and sizes may be flexibly accommodated.

In addition, when the large number of articles are ordered at one time, there may be the advantage that the storage box itself is carried to move, and it may be easy to move the article from the entrance refrigerator to the kitchen refrigerator.

Also, since the bottom portion of the storage box is detachable separately, the bottom portion of the storage box may be removed in the state in which the storage box is placed on the shelf of the kitchen refrigerator, and then the wall portion may be left, so there is no need to move the articles one by one.

Hereinafter, a storage box of an entrance refrigerator according to an embodiment of the present invention will be described in with reference to the accompanying drawings.

In this specification, an entrance refrigerator or a refrigerator for an entrance is used interchangeably, but they all have the same meaning, that is, a refrigerator mounted on a door or a wall of the entrance should be interpreted the same.

According to the invention, the base <NUM> is configured to have a variable width in the left and right directions, and at least one of the first sidewalls <NUM> and the second sidewalls <NUM> has a variable width in the left and right directions and a height in a vertical direction.

Particularly, when the width of each of the first sidewalls <NUM> varies in the left and right directions, the width of the base <NUM> also varies in the left and right directions.

Hereinafter, the structure having the variable width and height of the storage box <NUM> will be described with reference to the drawings.

<FIG> is a perspective view of the storage box in a state in which the widths of the base and the first sidewall increase, <FIG> is a longitudinal cross-sectional view of the first sidewall, taken along line <NUM>-<NUM> of <FIG> is a longitudinal cross-sectional view of the first sidewall, taken along line <NUM>-<NUM> of <FIG>.

In detail, the cross-sectional view illustrated in <FIG> is a cross-sectional view in a state before the width of the first side wall <NUM> varies, and the cross-sectional view illustrated in <FIG> is a cross-sectional view in a state in which the width of the first side wall <NUM> varies in a direction in which the width increases.

First, a structure in which the width of the first sidewall <NUM> is variable will be described.

Referring to <FIG>, in the first sidewall <NUM> according to an embodiment of the present invention, a plurality of blocks <NUM> are stacked vertically, and the plurality of blocks are disposed in the left and right directions. The plurality of blocks disposed in the left and right directions are movably connected by a plurality of connectors <NUM>. The block <NUM> may be defined as a first block.

A left guide groove <NUM> and a right guide groove <NUM> are formed inside the block <NUM>. A partition wall <NUM> is formed between the left guide groove <NUM> and the right guide groove <NUM>.

In addition, a left through-hole <NUM> is formed at a left side of the block <NUM>, and a right through-hole <NUM> is formed at a right side of the block <NUM>.

In addition, a left magnet <NUM> is embedded in an inner left edge of the block <NUM>, and a right magnet <NUM> is embedded in an inner right edge of the block <NUM>.

The connector <NUM> includes a connector body <NUM> extending by a predetermined length, a left hook end <NUM> extending from a left edge of the connector body <NUM>, and a right hook end <NUM> extending from a right edge of the connector body <NUM>.

The left hook end <NUM> and the right hook end <NUM> extend in a direction perpendicular to the connector body <NUM>.

The magnets <NUM> and <NUM> are embedded in the left hook end <NUM> and the right hook end <NUM>, respectively.

The connector <NUM> is a means for connecting the two blocks <NUM> to each other. The left hook end <NUM> is inserted into the right guide groove <NUM> of the block <NUM> disposed at the left side, and the right hook end <NUM> is inserted into the left guide groove <NUM> disposed at the right side. In addition, the connector body <NUM> passes through the right through-hole <NUM> of the block <NUM> disposed at the left side and the left through-hole <NUM> of the block <NUM> disposed at the right side.

According to this configuration, as illustrated in <FIG>, when the width of the storage box <NUM> is in the basic state, the right magnet <NUM> embedded in the right side of the left block <NUM> and the left magnet <NUM> embedded in the left side of the right block <NUM> are attached to each other by attractive force therebetween, and thus, side surfaces of the adjacent blocks <NUM> are maintained to be in a close contact with each other.

In this state, the hook ends <NUM> and <NUM> of the connector <NUM> may be spaced apart from the side surfaces of the left guide groove <NUM> and the right guide groove <NUM> and be disposed at an approximately intermediate point.

In order to increase in width of the storage box <NUM>, when the left and right portions of the storage box <NUM> are pulled in a width direction, a state as illustrated in <FIG> is obtained.

In the state of <FIG>, as illustrated in <FIG>, two adjacent blocks <NUM> are separated from each other.

In detail, when the left hook end <NUM> is in close contact with a right edge of the right guide groove <NUM> of the left block <NUM>, and the right hook end <NUM> is in close contact with the left edge of the left guide groove <NUM> of the right block <NUM>, the width of the storage box <NUM> may maximally increase.

In addition, the number of blocks <NUM> separated from each other in a lateral direction may be adjusted to adjust an increase in width of the storage box <NUM>.

<FIG> is a cutaway perspective view illustrating a state in which the width of the base constituting the storage box increases according to the present invention.

Referring to <FIG>, the base <NUM> constituting the storage box <NUM> according to the embodiment of the present invention is also provided as a combination of a plurality of base blocks <NUM>, like the first sidewalls <NUM>.

In detail, the base <NUM> includes a plurality of base blocks <NUM> arranged in the width direction, and a plurality of connectors <NUM> connecting the adjacent base blocks <NUM> to each other.

In the base block <NUM>, like the blocks <NUM> constituting the first sidewall <NUM>, a left guide groove <NUM> and a right guide groove <NUM> are formed therein, and the connector <NUM> includes a connector body <NUM> and left and right hook ends <NUM> and <NUM> respectively extending from both ends of the connector body <NUM>.

The left hook end <NUM> is accommodated in the right guide groove <NUM> of the left base block <NUM>, and the right hook end <NUM> is accommodated in the left guide groove <NUM> of the right base block <NUM>.

In addition, a left magnet <NUM> and a right magnet <NUM> are respectively embedded in inner left and right edges of the base block <NUM>, respectively.

Also, magnets <NUM> and <NUM> are also embedded in the left hook end <NUM> and the right hook end <NUM>, respectively.

Since the variation in width of the base <NUM> is the same as the method of varying in width of the first sidewall <NUM>, a description thereof will be omitted.

<FIG> is a perspective view of a state in which the storage box is adjusted in height according to an embodiment of the present invention, <FIG> is a longitudinal cross-sectional view taken along line <NUM>-<NUM> of <FIG>, and <FIG> is a longitudinal cross-sectional.

Referring to <FIG> and <FIG>, the first sidewall <NUM> of the storage box <NUM> according to the present invention has a plurality of blocks <NUM> stacked in the vertical direction, and two blocks <NUM> adjacent to each other in the vertical direction are connected to each other by a link member <NUM>.

In detail, a slide groove <NUM> to which an end of the link member <NUM> is connected is formed inside the block <NUM> constituting the first sidewall <NUM>. The slide groove <NUM> may have a length from a left end to a right end of the block <NUM>.

In addition, the slide groove <NUM> may be formed on each of front and rear surfaces of the block <NUM>.

A bottom surface of the uppermost block <NUM>, a top surface of the lowermost block <NUM>, and top and bottom surfaces of the block <NUM> placed between the uppermost and lowermost blocks are opened and designed not to interrupt the slide of the link member <NUM>.

In addition, the slide groove <NUM> may be formed at an upper side of the lowermost block <NUM> placed on the top surface of the base <NUM>, and the guide grooves <NUM> and <NUM> may be formed at a lower side.

The guide grooves <NUM> and <NUM> may be formed at the upper side, and the slide groove <NUM> may be formed at the lower side inside the block <NUM> placed at the uppermost side.

In addition, the slide grooves <NUM> are formed at the upper and lower sides, respectively, and the guide grooves <NUM> and <NUM> may be formed between the slide grooves <NUM> inside the blocks <NUM> stacked between the uppermost block <NUM> and the lowermost block <NUM>.

In addition, a plurality of restriction protrusions <NUM> may protrude from a bottom portion of the slide groove <NUM> to adjust a sliding position of the link member <NUM>.

The link member <NUM> may include a first link <NUM> and a second link <NUM> that intersect in an X shape, and points at which the first link <NUM> and the second link <NUM> intersect may be connected to each other a hinge shaft.

A slide protrusion <NUM> may protrude from each of both ends of the first and second links <NUM> and <NUM>. The slide protrusion <NUM> may protrude by a predetermined length from left and right sides of the links <NUM> and <NUM> and be inserted into the slide groove <NUM>.

In addition, when a height of the storage box <NUM> is adjusted by an operation in which the vertically adjacent blocks <NUM> move away from each other or close to each other in the vertical direction, the slide protrusion <NUM> passes over the restriction protrusion <NUM> providing from the bottom of the slide groove <NUM>.

In addition, when the vertical movement of the block <NUM> is stopped, the slide protrusion <NUM> is caught by the restriction protrusion <NUM> to prevent the upper block <NUM> from falling to the lower block <NUM>.

Referring to <FIG> and <FIG>, the second sidewall <NUM> is also formed in a form in which a plurality of blocks <NUM> are stacked, like the first sidewall <NUM>, and the plurality of stacked blocks <NUM> are connected to each other by a scissor link <NUM>. The block <NUM> may be defined as a second block.

Although it is illustrated that only the height of the second sidewall <NUM> is adjusted in this embodiment, according to this invention it is foreseen that the configuration of the second sidewall <NUM> is the same as that of the first sidewall <NUM>.

The means for adjusting the length of the second sidewall <NUM> in the front and rear directions may be determined according to the size of the storage compartment 110a of the entrance refrigerator.

On the other hand, the scissor link <NUM>, as illustrated in the drawings, is provided by connecting a plurality of link sets that intersect in an X-shape. In detail, hinge shafts <NUM> and <NUM> are inserted through a point at which two links constituting a link set intersect and both ends at which the plurality of link sets are connected to each other.

According to this structure, when a width of the scissor link <NUM> becomes narrow, the length of the scissor link <NUM> increases, and when the width increases, the length of the scissor link decreases.

In addition, the hinge shaft <NUM> inserted at the point at which the two links intersect is connected to the block <NUM>, and thus, the intersection point of the link set and the block <NUM> is elevated as one body.

Thus, when the height of the second sidewall <NUM> increases while the blocks <NUM> adjacent to each other are spaced apart from each other, a distance between the vertically adjacent blocks <NUM> increases.

One end of the support <NUM> may be rotatably connected to the lowermost link among the plurality of links constituting the scissor link <NUM>. In addition, a hook protrusion <NUM> may protrude from the bottom of the lowermost block <NUM> so that the other end of the support <NUM> is selectively hooked.

A manipulation protrusion <NUM> may protrude from a front surface of a support <NUM>, and a guide hole <NUM> through which the manipulation protrusion <NUM> passes may be formed in a front surface of the lowermost block <NUM>.

The guide hole <NUM> is a long hole extending in a direction inclined at a predetermined angle from a horizontal plane, and the manipulation protrusion <NUM> may protrude from the front surface of the lowermost block <NUM>.

Thus, the user lowers the manipulation protrusion <NUM> downward in a state in which the height of the second sidewall <NUM> is extended, that is, in a state in which the length of the scissor link <NUM> increases, to allow the other end of the support <NUM> to be hooked with the hook protrusion <NUM>, thereby preventing the plurality of blocks <NUM> from dropping downward by a load thereof.

In addition, in order to lower the second sidewall <NUM> to its original state, when the user pushes up the manipulation protrusion <NUM> so that the other end of the support <NUM> is released from the hook protrusion <NUM>, each of the plurality of blocks <NUM> descends by its own weight to return to its original state.

<FIG> is an exploded perspective view illustrating a state in which the base of the storage box is separable according to an embodiment of the present invention.

Referring to <FIG>, the base <NUM> forming the bottom portion of the storage box <NUM> is detachable from the first and second sidewalls <NUM> and <NUM>.

In detail, the order article is taken out from the entrance refrigerator <NUM> in a state in which the ordered article is stored in the storage box <NUM> to move to the kitchen refrigerator, and then the article together with the storage box <NUM> are accommodated in the kitchen refrigerator.

In this state, only the base <NUM> is slid forward to open a bottom portion of the storage box <NUM>. Then, the stored article is directly seated on a shelf of the refrigerator.

Thereafter, when the first sidewall <NUM> and the second sidewall <NUM> are lifted upward to a height that does not interfere with the article and then taken out of the refrigerator, it is unnecessary to take out the articles stored in the storage box <NUM> one by one.

For this, the magnets <NUM> are embedded and installed in four corners of a top surface of the base <NUM>, i.e., at fourth corners of a portion that is in contact with the lowermost first sidewall <NUM> or the lowermost second sidewall <NUM>.

In addition, the magnet <NUM> or <NUM> in which the attractive force acts with the magnet <NUM> is mounted also inside the first side wall <NUM> or the second side wall <NUM> corresponding to the directly above the magnet <NUM>.

<FIG> is a perspective view illustrating a state in which a plurality of storage boxes are stacked, and <FIG> is a cross-sectional view taken along line <NUM>-<NUM> of <FIG>.

Referring to <FIG> and <FIG>, a plurality of storage boxes <NUM> are capable of being stacked, and a means for preventing the stacked state of the storage boxes <NUM> from being easily released is proposed.

In detail, a stacking protrusion <NUM> may be formed on a top surface of the storage box <NUM>.

The stacking protrusion <NUM> may be formed on a top surface of each of the first sidewall <NUM> or the second sidewall <NUM>. Alternatively, it is also possible to be formed in all four places on the top surface of the storage box <NUM>.

In addition, a stacking groove <NUM> into which the stacking protrusion <NUM> is fitted may be formed in an edge of the bottom surface of the base <NUM> of the storage box <NUM>.

Furthermore, the magnet <NUM> may be embedded at an upper side of the stacking protrusion <NUM>, and the magnet <NUM> may be embedded in the base <NUM> corresponding to the upper side of the stacking groove <NUM>.
