Description
- The present invention relates to an automated cabinet assembly. More particularly, the present invention relates to an automated storage system having at least an inner cabinet and an outer cabinet. The system is configured with a cabinet moving mechanism to extend or retract and raise or lower the inner cabinet from the outer cabinet. The cabinet moving mechanism is configured to move the inner cabinet in between a retracted position, an extended position and a lower extended position or an upper extended position as required.
- A cabinet is a case usually having one or more doors and inner shelves used for items that are displayed or stored in a home, business, store, or elsewhere. It is raised off the floor and often anchored to a wall, supported on its shorter length sides by brackets, or otherwise anchored to a rigid surface by brackets, dowels, screws, or nails. The items can include paper files such as files and books, etc. According to the purposes and based on the items stored, the cabinets can be divided into archive cabinets, book cabinets, accounting cabinets, case cabinets, and storage cabinets. The emergence of dense cabinets eased the long-standing problem of warehouse tension and improved storage conditions. In order to retrieve items stored high up in the cabinet, a user needs to stand preciously on a ladder or on a stool or the like. This practice is dangerous, especially for children, elderly, and physically challenged persons.
- To overcome this problem, the cabinets are provided with pull down assemblies. Generally, these assemblies lower the inner cabinet using inherently complicated mechanism. The mechanism uses biasing members, linkage mechanisms and/or pulleys. the cabinet assemblies of these types are usually costly and lack reliability.
- Following are some of the attempts made to design cabinet assemblies in order to provide automatic moving mechanisms.
- JP2002096907A provides a trackless motor shelf that relates to an electric movable rack, and more particularly to a rail less electric movable rack whose wheels directly move on a floor without using rails. A pair of rail-shaped guides are arranged in parallel along a traveling direction at intervals from a back face of the moving shelf single body. A pair of front and rear axles orthogonally crossing a moving shelf single body traveling direction are provided by at least one pairs on a back face side and a front side, and the axles on the front side and axles on the back face side are driven by each of different electric motors.
- JP2017043461A provides a moving rack device and control method of moving rack device that relates to a movable shelf apparatus having a movable shelf movable on a floor surface in a facility and a control method of the movable shelf apparatus. Before the movement of moving racks, it is confirmed whether or not an obstacle exists about the whole of an inter-rack passage which is opened to a front side of the moving racks in a forward direction by the determination of the detection of the existence of the obstacle in a pre-movement detection range by an obstacle sensor, and after a start of the movement.
- CN209543442U provides an unmanned shelf replenishment system that relates to a product sales management system based on a two-dimensional code.
- Although there are a number of solutions in the form of the automatic cabinet assembly, none of them are solving the same problems-of accessibility of shelves for a user. Although some of the prior existing assemblies attempt to create an automatic cabinet with a moving mechanism, the solution fails to meet the user's requirement if a cabinet is high up the wall. In the view of the above prior art, it can be understood that many automatic cabinet moving assemblies have been designed in an attempt to provide solutions, however, they are either complex or expensive, not solving the same problems, and inefficient.
- In the light of the foregoing, there is a need for an automatic pull-down cabinet assembly that overcomes problems prevalent in the prior art.
- It is an object of the present invention to provide an automatic pull-down cabinet assembly that uses a simple moving mechanism that allows a user to adjust the height required at a lower extended position and at an upper extended position.
- It is another object of the present invention to provide an automatic pull-down cabinet assembly that reduces human efforts and can be easily and safely operated by children, elderly, and physically challenged persons.
- It is another object of the present invention to provide an automatic pull-down cabinet assembly that limits the extension of a cabinet assembly when at the lower extended position or at the upper extended position.
- Yet another object of the present invention is to provide an automatic pull-down cabinet assembly that is reliable, cost-efficient, durable, less complex, and compact.
- Furthermore, the object of the present invention is to provide an automatic pull-down cabinet assembly, wherein the assembly can be easily anchored to a rigid surface such as a wall.
- Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of the embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

The second direction is the anticlockwise direction or the clockwise direction. The firstprime mover 110 is an AC motor or a DC motor. When the firstprime mover 110 moves in the first direction or in the second direction, the first movingunit 108 moves in the forward direction for moving theinner cabinet 102 in the extended position. When the first movingunit 108 moves in the forward direction, the first set of slidingarms 112 slides theinner cabinet 102 in the forward direction to ensure theinner cabinet 102 achieves the extended position. - Further, the controller receives the command for moving the
inner cabinet 102 from the extended position to the retracted position from the user via theoperating device 105. Upon receiving the command, the controller actuates the firstprime mover 110. When the firstprime mover 110 moves in the second direction or in the first direction, the first movingunit 108 moves in the reverse direction for moving theinner cabinet 102 in the retracted position. When the first movingunit 108 moves in the reverse direction, the first set of slidingarms 112 slides theinner cabinet 102 in the reverse direction in the retracted position. - Furthermore, the controller receives the command for moving the
inner cabinet 102 from the extended position to the lower extended position from the user via theoperating device 105. Upon receiving the command, the controller actuates the secondprime mover 111. When the secondprime mover 111 moves in the first direction or in the second direction, the second movingunit 109 moves in the downward direction for moving theinner cabinet 102 to a required height. When the second movingunit 109 moves towards the lower extended position, the second set of slidingarms 113 slides theinner cabinet 102 to the lower extended position at the required height. - Further, the controller receives the command for moving the
inner cabinet 102 from the lower extended position to the extended position from the user via theoperating device 105. Upon receiving such a command, the controller actuates the secondprime mover 111. When the secondprime mover 111 moves in the second direction or in the first direction, the second movingunit 109 moves in the upward direction for moving theinner cabinet 102 to a predefined height. When the second movingunit 109 moves in the upward direction, the second set of slidingarms 113 slides theinner cabinet 102 towards the extended position to the required height. - In an alternative embodiment of the present invention as shown in
FIG. 9 , theouter cabinet 101 is installed on the ground surface. Thecabinet moving mechanism 103 moves theinner cabinet 102 between the retracted position, the extended position, and an upper extended position. The one or more slidingarms 104 slides theinner cabinet 102 between the retracted position, and the extended position. Thereafter, one or more linear actuators 109 (in an example, two such linear actuators) move the inner cabinet to the upper extended position from the extended position. The controller enables thecabinet moving mechanism 103 to move theinner cabinet 102 from the retracted position to the extended position to the upper extended position and vice versa as per the command received. - The
assembly 100 further includes a plurality of sensors for monitoring the articles kept inside theinner cabinet 102 and arranged on the one ormore shelves 107. The plurality of sensors includes a proximity sensor, a displacement sensor, a vision sensor, a scanner, a position sensor, an IR sensor, and a UV sensor. In a given example, the position sensor senses the position of theinner cabinet 102. The displacement sensor senses the displacement of theinner cabinet 102 when moved between the retracted position to the extended position to the lower extended position or upper extended position. The vision sensor may be a camera or a thermal camera that captures the images or records a video of articles kept inside theinner cabinet 102. The vibration sensor senses a vibration generated while moving theinner cabinet 102. It is known to a person ordinary skilled in the art to configure known sensors within theassembly 100. The sensors send the sensed data to the controller. - In a given example as shown in
FIGS. 8 and 10 , the user needs to give the command to theassembly 100 in order to move theinner cabinet 102 using theoperating device 105. After getting the further command from the controller, thecabinet moving mechanism 103 moves theinner cabinet 102 connected therewith to the user's reach. After collecting the required articles from theinner cabinet 102, the command is given toassembly 100 to move theinner cabinet 102 using theoperating device 105. After getting the command, thecabinet moving mechanism 103 moves back theinner cabinet 102 inside theouter cabinet 101. - The present invention provides the automatic pull-down
cabinet assembly 100. Theassembly 100 uses the movingmechanism 103 wherein the user is allowed to adjust the height required at the lower extended position. Theassembly 100 reduces human efforts and can be easily and safely operated by children, the elderly, and physically challenged persons. Theassembly 100 provides a provision to limit the extension of thecabinet assembly 100 when at the lower extended position and at the upper extended position. Theassembly 100 is reliable, cost-efficient, durable, and compact. Theassembly 100 can be easily installed with existing article storing cabinets. - It should be understood according to the preceding description of the present invention that the same is susceptible to changes, modifications and adaptations, and that the said changes, modifications and adaptations fall within scope of the appended claims.
