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.

A cabinet is a case usually having doors and shelves used for items that are displayed or stored in a home, business, store, or elsewhere. The present invention provides an automatic pull-down cabinet assembly with at least an outer cabinet and an inner cabinet. The assembly uses a moving mechanism that allows the user to adjust the height of the inner cabinet as required at a lower extended position and at an upper extended position. The assembly reduces the human efforts and can be easily and safely operated by children, elderly and physically challenged persons. The assembly provides a provision to limit the extension of the inner cabinet when the inner cabinet is moved to the lower extended position or to the upper extended position.
From herein afterward the assembly is referred to as an assembly 100. Referring now to
The outer cabinet 101 is mounted to a rigid surface. Generally, the outer cabinet 101 is anchored to a wall. The inner cabinet 102 is movably arranged inside the outer cabinet 101. In one embodiment, as shown in
A power source provides energy to the assembly 100. The power source is a battery or a rechargeable battery. In one embodiment, the energy is provided to the assembly 100 using an external power source.
The cabinet moving mechanism 103 moves the inner cabinet 102. The inner cabinet 102 is movable between a retracted position, an extended position, and a lower extended position or an upper extended position. The cabinet moving mechanism 103 includes a first moving unit 108 and a second moving unit 109 (as seen in
The second moving unit 109 is rigidly mounted to the first moving unit 108. The second moving unit 109 is movably mounted to the inner cabinet 102. The second moving unit 109 receives a motion from a second prime mover 111 for moving the inner cabinet 102 between the extended position and the lower extended position. The second moving unit 109 includes a gear arrangement, a linear actuator, a lead screw arrangement, a belt drive arrangement, a chain drive arrangement, a scissor arm arrangement, a lever arm, a telescopic arm, a sliding arm, a pneumatic arm, a hydraulic arm, or any other transition mechanism.
The sliding arms 104 slide the inner cabinet 102 between the retracted position, the extended position, and the lower extended position as seen in
The controller is a controller or a processor or a microcontroller or a microcomputer or a microprocessor. The controller receives a command for moving the inner cabinet 102 from the user using the operating device 105 through a communication module. The communication module is a wired communication module or a wireless communication module. The well-known wireless communication modules are a radio frequency, a Wi-Fi, an internet and a Bluetooth. After receiving the command, the controller enables the cabinet moving mechanism 103 to move the inner cabinet 102 from the retracted position to the extended position to the lower extended position and vice versa.
In the preferred embodiment of the present invention, a command is received from the user for moving the inner cabinet 102. The operating device is a knob, a pressure switch, a mechanical switch, an electromagnetic switch, an electromechanical switch, a press button, and a hand lever. In one alternative embodiment of the present invention as shown in
The controller receives the command for moving the inner cabinet 102 from the retracted position to the extended position from the user via the operating device 105. Upon receiving the command, the controller actuates the first prime mover 110. The first prime mover 110 rotates in a first direction or in a second direction. The first direction is a clockwise direction or an anticlockwise direction. The second direction is the anticlockwise direction or the clockwise direction. The first prime mover 110 is an AC motor or a DC motor. When the first prime mover 110 moves in the first direction or in the second direction, the first moving unit 108 moves in the forward direction for moving the inner cabinet 102 in the extended position. When the first moving unit 108 moves in the forward direction, the first set of sliding arms 112 slides the inner cabinet 102 in the forward direction to ensure the inner 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 the operating device 105. Upon receiving the command, the controller actuates the first prime mover 110. When the first prime mover 110 moves in the second direction or in the first direction, the first moving unit 108 moves in the reverse direction for moving the inner cabinet 102 in the retracted position. When the first moving unit 108 moves in the reverse direction, the first set of sliding arms 112 slides the inner 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 the operating device 105. Upon receiving the command, the controller actuates the second prime mover 111. When the second prime mover 111 moves in the first direction or in the second direction, the second moving unit 109 moves in the downward direction for moving the inner cabinet 102 to a required height. When the second moving unit 109 moves towards the lower extended position, the second set of sliding arms 113 slides the inner 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 the operating device 105. Upon receiving such a command, the controller actuates the second prime mover 111. When the second prime mover 111 moves in the second direction or in the first direction, the second moving unit 109 moves in the upward direction for moving the inner cabinet 102 to a predefined height. When the second moving unit 109 moves in the upward direction, the second set of sliding arms 113 slides the inner cabinet 102 towards the extended position to the required height.
In an alternative embodiment of the present invention as shown in
The assembly 100 further includes a plurality of sensors for monitoring the articles kept inside the inner cabinet 102 and arranged on the one or more 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 the inner cabinet 102. The displacement sensor senses the displacement of the inner 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 the inner cabinet 102. The vibration sensor senses a vibration generated while moving the inner cabinet 102. It is known to a person ordinary skilled in the art to configure known sensors within the assembly 100. The sensors send the sensed data to the controller.
In a given example as shown in
The present invention provides the automatic pull-down cabinet assembly 100. The assembly 100 uses the moving mechanism 103 wherein the user is allowed to adjust the height required at the lower extended position. The assembly 100 reduces human efforts and can be easily and safely operated by children, the elderly, and physically challenged persons. The assembly 100 provides a provision to limit the extension of the cabinet assembly 100 when at the lower extended position and at the upper extended position.
