The present invention relates to the field of storage and furniture technology.
Storage volume is an essential, valuable characteristic of houses, store houses, warehouse etc. Wardrobes, chest of shelves, chests of drawers and cabinets are used as a major storage medium, but too many of them in a given space, especially if they are all on the floor, become an obstacle, as well as an overcrowding, aesthetic problem. Storage space shortage of every-day items is acute in small apartments and studios, comprising only one or two rooms. Almost every built space comprises free volumes close to the ceiling, and even though they have the potential of being used instead of occupying floor areas, they are not utilized in prior art, mainly because of the lack of a comprehensive affordable price solution.
U.S. Pat. No. 8,414,093: This patent is intended for disabled people on wheelchair, it deals with lowering of shelves from within an upper kitchen cabinet to the worktop level, this is done by simultaneously performing two movements, in the vertical and the horizontal direction; the last requires opening of the relevant cabinet doors.
Our invention is primarily intended for the general population and furthermore, not only for kitchens; only vertical movement is performed and an affordable common used motion system is used.
With the Highly Hung Vertical Moveable Cabinet (HHVMC), and CORNER HHVMC the whole cabinet is moving up and down and not only the shelves.
With the SHAFT CORNER HHVMC our patent refers only to the corner between the upper cabinets of a kitchen, the referred patent could not be apply in this case because the movement in the horizontal side is impossible (there are no doors to be opened . . . ). US20140197720: This patent application is also intended for disabled people on wheelchair, it deals with lowering one cabinet from within a wider one; again a simultaneous movements are used, one in the vertical and the other in the horizontal direction;
This invention is similar to the previous one, except that it saves the need for completely redesigns and/or reinstalls the cupboards and/or cabinets, but to use existing ones as the inner movable items.
US2011/0298346: This patent application deals with lowering cabinets in the vertical direction. This invention does not include electrical motion system; lowering and lifting of the cabinet is performed by the user power; as such, the cabinets are limited to a small insufficient storage loads.
Vertically moveable cabinets, designed to increase storage capacity, while not occupying valuable floor areas. This is achieved by using high, close to the ceiling room volumes, including above windows and doors spaces and vertical room's corners, which are rarely used in prior art. The suggested cabinets are installed with a large enough clearance to the floor, and thus do not risk nearby persons, or overcrowd the room.
Stored items are easily reached by lowering the cabinets to an accessible height. The suggested motion system is a novel use of a prior art tubular motor and accompanying accessories, which are widely used for lifting and lowering shutters and blinds. Protection against a possible dropping, due to a technical failure, is accomplished by adaption of retractable vehicle safety belts. Stabilization of the vertical path is achieved by telescopic rails.
Some of the concepts described above are further used to enhance the usage and accessibility of corner volumes of corner kitchens cabinets.
The suggested invention would be of great benefit to the wide population and particularly to disabled people and children having difficulties reaching elevated stored items.
According to one aspect, a Highly Hung Vertically Moveable Cabinet (HHVMC) is provided, comprising:
A cabinet having a bottom and a top essentially parallel thereto;
An electrical motion system configured to allow movement of the cabinet to a predetermined distance of at least 500 mm in a first direction and in a second opposite direction, both first direction and second direction being essentially normal to the cabinet bottom and top, and switches electrically coupled to the motion system, wired to allow selection of the movement in the first or second direction.
The HHVMC further comprises at least two telescopic rails configured to allow stabilization of the movement.
In some embodiments the HHVMC is shaped as a right angle triangular prism with door/s at a hypotenuse of the prism (a CORNER HHVMC).
Further provided is a SCVMC (Shaft Corner Vertically Moveable Cabinet), intended to installation within the trapped volume between the higher or lower cabinets of a corner cabinet kitchen. The SCVMC comprises a vertically movable insert cabinet installed within a trapped volume of corner kitchen cabinets
According to another aspect, an array of HHVMCs is provided, installed in structures selected from a group comprising warehouses, storehouses, exhibition halls and houses, wherein the HHVMCs are installed one next to another and proximal to ceiling areas in the structures;.
In the array the structures may comprise floors, and wherein the cabinets of the HHVMCs are installed such that a distance between the cabinet bottom and the floor is at least 1900 mm.
The cabinet top comprises in some embodiments a groove housing at least part of the electrical motion system.
The electrical motion system may comprise a motor and a curtain, the curtain is fully rolled into the groove when the cabinet is proximal to the ceiling. The HHVMC may further comprise means to allow manually moving the cabinet the predetermined distance in at least one direction.
According to another aspect, a method is provided comprising:
Providing a Highly Hung Vertically Moveable Cabinet (HHVMC) and an electrical motion system; installing the HHVMC at the upper volume of a built space with some 1900 mm clearance between a bottom of the HHVMC and a floor of the built space, in the up most travel position of the HHVMC, the clearance furthermore enabling installation above windows and doors in the built space; wherein the HHVMC has an aspect ratio higher than 1:1; and to gain asses to stored items in the HMMVC, the HHVMC is lowered some 500 mm and more by the electrical motion system; and wherein stabilization of the vertical motion is based on two or more telescopic rails.
In some embodiments the HHVMC is shaped as a right angle triangular prism with door/s at its hypotenuse (a CORNER HHVMC), allowing good accessibility to stored items within the HHVMC, wherein the HHVMC is installed at vertical corners of the built space.
In some embodiments there is provided SCVMC and an electrical motion system; installing the SCVMC at a shaft formed by a kitchen room corner and upper or lower kitchen wall cabinets proximal thereto; lowering and lifting the SCVMC in a space behind the kitchen wall cabinets, by the electrical motion system; and stabilizing the lowering and lifting with two or more telescopic rails.
Some embodiments further comprise restraining dropping due to technical failure of the HHVMC or SCVMC with retraceable vehicle safety belts.
In some embodiments the cabinet top comprises a groove housing at least part of the electrical motion system.
In some embodiments the motion system comprises a curtain, or at least one strap used as a medium to lift and lower the HHVMC or the SCVMC by wrapping/unwrapping round a rotating axle.
According to another aspect a method is provided of installing an array of HHVMCs in built spaces selected from a group consisting of: warehouses, storehouses, exhibition halls etc, wherein the HHVMCs are installed one next to the other on ceiling areas in the built spaces; whereby the HHVMCs arrays provide large storage volume in high zones of the built spaces.
The suggested invention deals with using the top space of rooms as storage spaces, without occupying floor areas, or risking the users or nearby passing persons; this is achieved by HHVMC. HHVMCs located above persons heads, near the ceiling corners, and/or above windows and doors.
Especially with warehouses and store houses, this idea might be extended to an array of HHVMCs, installed each next to the other, on ceiling areas, hence freeing the floor for wide, open and comfortable merchandise exhibition and traffic.
Some of the benefits of this invention are suggested for more efficient storage volume and improved accessibility of prior art, corner kitchen cabinets.
In a first aspect, the suggested solution is directed to a HHVMC comprising chests of drawers or chests of shelves (later on, all referred to as HHVMC).
HHVMCs are hung with a clearance of some 1900 mm from the floor,
In some cases, especially above windows, the remaining clearance to the ceiling would be less than 500 mm.
To compensate for the relatively low height and storage volume, two major solutions are given:
a. The HHVMC may have a very large aspect ratio, starting with 1:1 and ending with 10:1 and more (width over height).
b. The motion system (7, in
The large aspect ratio of a moving cabinet may lead to large deflection, the solution to this problem is achieved by hanging the cabinet on a “curtain” all along, so that the load is equally divided and carried against the rigid structure side of the curtain and a rigid tube carrying the curtain.
The HHVMC is moved up and down to provide the users with good accessibility to the stored items. To achieve that, the HHVMC ceiling is lowered a distance of some 500 mm , to some 1900 mm from the floor as shown in
In a second aspect, the present invention is directed to the use of a prior art tubular motor, as means for vertically moving HHVMC and SCVMC; in prior art, this kind of motors and the accompanying mounting accessories is in wide use to automatically operate shutters and blinds only.
The use of a tubular motor for lifting and lowering cabinets is novel.
The following is a list of the advantages of the prior art tubular motor assembly (7), for the novel suggested usage in HHVMC or SCVMC:
These kinds of motors are compact and supplied with an electrical power capacity ranging from several to some 900 Watts; the diameter range of the extendable tube is 30-130 mm; those ranges suit well the need for the new suggested embodiment for HHVMCs of up to some 600 kg gross weight, with reasonable traveling velocity and compactness.
The tubular motor includes integral motion limit control: two switches (14) mounted on the motor, are set once to control the number of turns to be performed in each turning direction; activating and altering direction is achieved by a switch mounted on the wall, or by a remote control—this also fits well the novel use for HHVMCs or SCVMCs.
The stroke of tubular motors is very flexible to adjust, and can easily be set to 500 mm and more if needed—This fits well the novel use with HHVMCs or SCVMC
The switch or the remote control operating the motor has three states: a lifting state, for lifting to the upmost position; an intermediate state, to stops anywhere in the range of movement; and a lowering state, for lowering to the lowermost position—this also, fits well the novel use for HHVMCs or SCVMCs.
Tubular motors have a further advantage of improved safety of the elevation position, since the off position, as well as a voltage cut-off failure, cause integral braking, thus the HHVCM stops as needed, and cannot drop upon cease of electric power supply—this also, fits well the novel use for HHVMCs and SCVMCs.
Tubular motors systems are also available with a backup manual operation mechanism, this might be relevant for areas suffering from frequent voltage cut-offs (for other cases a ladder may be a satisfactory backup solution)—this also, fits well the novel use for HHVCMs. Tubular motors are produced in mass quantities worldwide, thus have affordable price.—This fits well the novel use for HHVMCs and SCVMCs.
It could be summarized that prior art tubular motor systems used so far for the motion of shutters and blinds, are ideal for the suggested novel usage of HHVMC or SCVMC (a specific tubular motor and accessories still must be selected, referring to the gross cabinet weight, width and the required velocity).
In a third aspect, the present invention refers to a novel use of a prior art retractable seat belts, as a mean for restraining accidental drop of HHVMCs or SCVMCs in case of a mechanical failure. A retractable seat belt is “a vehicle safety device designed to secure the occupant of a vehicle against harmful movement that may result during a collision or a sudden stop” (Wikipedia).
The following is a list of the advantages of prior art retractable seat belts for the novel suggested usage:
Retractable seat belt allows the movement of the restrained person/object with only small force, as long as a negligible acceleration is involved, this is done by unwrapping an extra belt length needed to allow this movement, against a “constant torque” torsion spring, the unwrapping mechanism comprises a centrifugal brake that firmly stops the movement in case of a sudden increased velocity (acceleration)—This fits well the need for restraining a falling HHVMCs or SCVMCs, the belt allows a normal movement with only negligibly overloading the motor on one hand, and on the other hand prevents falling by responding to the gravity acceleration in case of a mechanical failure.
Retractable seat belts are produced in mass quantities and under severe quality requirements, and thus combine high reliability with affordable price.—This fits well the novel use for restraining HHVMCs or SCVMCs.
Retractable seat belts are designed to deal with high impact loads of some 75 kg, exposed to tens of “g”, thus can easily deal with loads of falling HHVMCs, weighing hundreds of kg with only one “g” of gravity acceleration.
With large aspect HHVMCs the suggested requirement for cabinets restraining mechanisms would be at least two retractable seat belts, at two different sides of the lateral (wide) centre of gravity of the HHVMC, this gives an extra margin of safety.—This fits well the novel use for restraining HHVCMs.
Retractable seat belts have a stroke of some 1500 mm—This stroke, fits the novel use for eased installation and use with restraining HHVMCs or SCVMCs.
It could be summarized that retractable vehicle seat belts are an ideal novel use for restraining HHVMC and SCVMC; depending on the aspect ratio of the HHVMC, the number of required retractable belts may be more than one.
Preferred embodiments, features, aspects and advantages of the present invention, are described herein in conjunction with the following drawings. In principle the drawings are drawn to scale, but not as a mandatory issue. All sizes are in millimeters.
The present invention will be understood from the following detailed description of preferred embodiments (“best mode”), which are meant to be descriptive and not limiting; for the sake of brevity, some well-known features, components, circuits, and so on, are not described in detail.
Size 1900 represents a safe clearance for nearby people, allows installation above windows and doors and minimizes room overcrowding. Sizes 500 and 2000 depict a recommended large aspect ratio intended to gain maximal storage volume on one hand and an esthetic “wall to wall” installation; on the other hand, the demonstrated 1:8 aspect ratio should not be considered as an upper limit.
To facilitate mobility trough gates, elevators, etc. the HHVMC may be made of modular pieces assembled each to other at the installation site; in the depicted case, each door represents a separate module; larger sizes HHVMCs may be split into more sub-units as needed.
The motion system is not shown, but in any case it could hardly be seen, as it is hidden behind the HHVMC in looking at the HHVMC doors direction and among the HHVMC side walls and the room walls from other views directions.
It should be noted that during the HHVMC motion, the wing window (3) must be fully closed or fully opened.
To prevent collision with possibly installed objects on the wall, such as shutter cover (5), the suggested solution comprises a deliberate gap (8), between the HHVMC backside and the wall.
Tubular tube assembly (7) is installed into one side wall through holes (15), and to an opposite wall bearing via fitting cup (12).
When electrically activated, rotor (10), extendable tube (9) and cup (12) rotate together round bearing (11) as one pivot, while the cup (12) serves as a second rotating pivot. In prior art, a shutter or a blind connected to the tube (9) wraps or unwraps in accordance with the rotation direction, in the novel suggested usage, a curtain or straps connected to tube (9) on one side and to HHVMC roof on the other side are used to vertically move the HHVMC, this method largely reduces possible cabinet deflections.
The suggested HHVMC movement is guided by two telescopic rails (20), connected to consoles (18), (one pair of console and rail is hidden behind “curtain” (16)). Further detailed explanation for this embodiment is given in conjunction with the coming figure.
“Curtain” (16), is all along attached to extendable tube (9) of tubular motor assembly (7), on one side and to a groove in the HHVMC roof, on the other side; rotation of tube (9), due to the tubular motor action, wraps/unwraps “curtain” (16), hence lifts or lowers the HHVMC.
As the HHVMC reaches the ceiling, tubular motor assemblies (7) together with the wrapped “curtain” (16) are entering the “U” shape groove opening, allowing for the HHVMC roof to almost touch the ceiling.
A reversed installation is also possible, to say: tubular motor assembly (7) is installed within the “U” shaped groove, while “'curtain” (16) is connected to the room ceiling; the minor drawbacks of this inversion are: the extra load on the motor that has to carry its own weight and in addition, the electrical supply cable to the motor, has to move together with the HHVMC (this reversed installation method is described later on, in conjunction with a CORNER HHVMC).
Two retractable car safety belts (19), are connected to belts consoles (18), on one side and to the upper HHVMC vertical interior surface on the other side (belt retracting mechanism (21) is shown in
This uncommon shape of CORNER HHVMC is applicable where only small to medium amount of extra storage volume is needed; and in view of esthetical considerations. As in the figure, the two arms of the prism are not necessarily equals (could be helpful to deal with existing obstructions on the walls). As for the HHVMC, the CORNER HHVMC is hung on a “curtain” (16) connected to prior art tubular motor assembly (7) and vertically guided by two telescopic rails (hidden by the CORNER HHVMC and the curtain in this figure). As in previous case, rotation of the tubular motor wraps/unwraps curtain (16) to lift and lower the CORNER HHVMC as needed. More detailed explanation for this embodiment is given in conjunction with the coming figure.
The suggested solution for this case is a SHAFT CORNER HHVMC. It should be noted that this solutions may be extended to size “A” and “B” (and not only for the heavy dotted area mentioned earlier.
Like the two previously described HHVMC and the CORNER HHVMC, the solution is based on the following building stones:
Views “A” and “B” demonstrate the upper level position, while views “C” and “D” represent the lower one.
Tubular motor assembly (7), is installed above the upper SCVMC (34), with one end attached to the wall of the nearby stationary cabinet (30), while the other end is installed to the room wall; strap (35) is wrapped/unwrapped on the tubular motor assembly (7), to lift and lower the upper SCVMC (34); two telescopic rail (20) guide the upper SCVMC (34) in a vertical route.
Another installation option is hanging the tubular motor assembly (7) further higher, on top of cabinet (30) roof, thus more efficiently using the 700 mm height for storage volume; in this case, some esthetical price is involved, resulting from the visibility of the tubular motor assembly on top of stationary cabinets (30). One more installation option is to connect tubular motor assembly (7) to the roof of the upper SCVMC (34), in a similar way described in
Prior art switch (36) (used to operate shutters and blinds), is used for lifting and lowering SCVMCs (34) and other depicted HHVMCs.
Views “A” and “D” demonstrate the lower and upper level position, while the other views depict a suggested installation design.
Tubular motor assembly (7), is attached to the bottom of the lower SCVMC (37), two straps (35) are wrapped/unwrapped on the tubular motor assembly (7), the straps are attached to two strap anchoring brackets (40) positioned on a sheet metal shell construction (41) surrounding the lower SCVMC; two telescopic rail (20) connected to the sheet metal shell guide (41) one side and to the lower SCVMC (37) wall in the other side guide the lower SCVMC in a vertical route.
To avoid liquid leakage from the worktop down to the lower cabinets, an elevated banister (38) surrounds the opening in the desktop surface.
Due to esthetical consideration it is suggested that the lower SCVMC roof (39) is made of the same worktop material.
