Definitions

  • the present invention relates generally to rotating storage structures that are used for supporting, holding and safekeeping objects- More particularly, the present invention relates to a reversing storage cabinet.
  • a typical structure such as a cabinet, furniture, et cetera, may contain rotatable unit(s), for example, a cabinet may have a "lazy Susan" tray-
  • rotatable units have widespread applications from cabinetry design to sophisticated high precision equipment-
  • cabinetry design to sophisticated high precision equipment-
  • rotatable units within a structure on the market There are a number of commercially available designs with regard to rotatable units within a structure on the market.
  • the first disadvantage is loss of space because these conventional designs require significant space around the rotating object so that it can perform a rotation around an axis.
  • Space loss in the front of the cabinet can typically be seen as temporary loss because the space is lost only when the cabinet is rotating.
  • the space loss is more wasteful when space is lost behind the cabinet.
  • Space loss behind a cabinet is typically considered permanent loss of space because such space has no practical utilization or compensation temporary or XXX.
  • Such permanent loss of space is illustrated in various conventional desig ⁇ s, such as those described in US Patent No. 4,610492 by Molander et al (1986) and US Patent No. 6,273,531 by Scheffer (2001).
  • Another conventional design for rotating an object within a structure uses non- obstructive rotation. To provide non-obstructive rotation of an object or cabinet, it is permanently moved forward away from a wall or other structure.
  • a drawback associated with this design is space loss in front of the cabinet. This type of space loss can become a serious problem if space is at premium
  • a second disadvantage associated with some conventional designs is lack of exclusive access-
  • Conventional designs do not typically offer exclusive accessibility to one side of the storage cabinet while other sides of the cabinet are not accessible. This is not suitable when alternative access to different sides is needed. Examples of these situations are the cabinets in which one of the cabinet sides is used for jewelry or expensive collectibles while another side of the cabinet stores firearms, etc.
  • conventional designs offer some designs including special enclosures and shields as such those described in US Patent No- 4,610492 by Molander et al (1986).
  • providing special enclosures and/or shields as solutions are typically impractical in terms of convenience or cost, e.g. when storage cabinet is used for relatively large articles (books, TV sets, etc.).
  • a problem associated with the above-referenced designs is safety. For example, if the weight of stored articles in a cabinet is greater then the weight of the cabinet itself, the loaded cabinet can become heavy and cumbersome to rotate and may also create safety issues because it could tip over if it is not supported from the top. However, providing support from the top may increase the complexity and bulkiness of such designs and may also increase the total cost of the storage cabinet. [0009] As mentioned, the problem in these conventional designs is waste of space. In the case of a bookcase in which the bookcase has two storage sides for accessing stored articles waste of space is significant in conventional rotating designs.
  • a known solution employs a cam system including cam followers and grooves to resolve the problem of waste of permanent space behind a shelf in a cabinet as described in US Patent No. 4,124,262 by Schill (1978).
  • the disclosed cam system can reduce extra space needed for rotation.
  • the rotating shelf within the cabinet does not require a big clearance -for rotation.
  • the center of the shelf is moved forward on its two (top and bottom) centered cam followers sliding in the transverse grooves of the enclosure- A pair of followers, mounted on opposite sides of the rotating shelf, guideone side to the opposite side of the stationary enclosure. In order for this rotation to perform correctly, these must be accurate grooves in the enclosure.
  • cam system reduces the problem of space waste, it generates new problems.
  • a problem associate with the cam system is uneven loading of the cabinet weight.
  • the cam system loads the entire weight of the shelf with its content on the bottom center cam follower.
  • the bottom center cam follower In addition to supporting the shelf during the rotation, the bottom center cam follower also guides itself along the transverse groove through out the enclosure. This multi-functionality of the central bottom cam follower lowers the reliability and lifetime of the cabinet.
  • Another problem associate with the disclosed cam system is that upper and lower cam followers move independently of each other in the guides. There is no guarantee that these guide will move synchronously- Quite to the contrary, one cam always will tend to move faster than another. This will happen for two reasons.
  • FIG 1 of US Patent No. 4,124,262 also shows wasted space on the left and right sides of the cabinet. In order to compensate for some of this waste, the left and right sides of the shelf are of cylindrically shaped- This design prevents two or more such cabinets to be placed next to each other in close proximity without wasted space. When the user has more than one cabinet it is advantageous to place them next to each other without wasted space for convenience of use and also for saving the total space allocated for the cabinets.
  • the present invention comprises a compound movement link mechanism that allows an object to move from the space it occupies in one orientation and return to the same space in a different orientation.
  • the object is a support structure having at least two selectively accessible sides.
  • the object is supported by a pair of synchronis compound movement link mechanisms.
  • a further objective of the invention is to provide limited access to the side or sides of the cabinet that are not being accessed at a given time. This secure access should be achieved economically and with simplicity of design.
  • a still further objective of the invention is to provide a storage cabinet that can be utilized for applications with heavy loads such as for example storing books, firearms, electronic equipment, etc.
  • Another objective of the invention is to provide a storage cabinet that can be simple in design with low cost for light load applications such as for example CD's, DVD's, stamp collections, etc.
  • a reversable storage cabinet with alternatively accessible sides includes a storage structure, which is used to hold at least one article.
  • Means for holding the storage structure includes a four-link mechanism, wherein three of the links are serially connected.
  • the three serially connected links are rotatably connected to two outside ends of a fourth link at two substantially separated locations- The fourth link is substantially stationary.
  • the middle link of three serially connected links is a part of the storage structure allowing reorientation of the storage structure relative to the fourth stationary link for alternative access to the sides of storage cabinet.

This cross-section shows standard design of the all links and their hinged connection to the stationary base 1202 and to the movable link 1104 where it is at the same time the bottom plate of the storage 1102.
  • Joints 1312 and 1316 in this embodiment are constructed substantially the same. For simplicity of the example, joints 1312 and 1316 are shown without special rotation bearings. Joints 1312 and 1318 are made from metal.
  • Link 1308 is made from plastic with good tribo logical performance to provide good friction pair to the joints.

Also these figures demonstrate the principle of how these implementations work. To simplify the demonstration of working principle of present invention, only bottom plate 104 of rotating storage is shown.
  • FIG 5A illustrates a bottom plate 104 of the reversible storage system 100 at points B and C connected respectively by revolute joints 314 and 316 to links 304 and 308. Outside ends of the links 304 and 308 connected by revolute joins 310 and 312 to stationary base 202.

  • joints A and D should be outside of the bottom plate 104 (or plate 104 should be shorter than link AD).
  • revolute joints A and D are located at remote sides of the stationary base generally in the middle area of short, left and right sides of the storage frame. Points B and C for revolute joints 314 and 316 are located on different sides of the line AD generally symmetrically relative to this line. Also joints B and C located at the middle of the front and backsides of the bottom plate 104. In order for bottom plate 104 to rotate between alternate positions spaced generally 180° apart BC is generally perpendicular to AD in starting position of the storage, i.e. FIG 5 A.
  • FIGS 5B - 5E The process of reversing the position of the plate 104 (i.e. movable storage) from the starting position of FIG 5A to 180° reversed final position in increments of 45° is shown on FIGS 5B - 5E.
  • Rotation of the plate 104 starts by pulling right side of the movable object represented here by plate 104 in direction from back to front.
  • FIGS 5B - 5D storage as represented here by bottom plate 104 is not crossing backside of the stationary plate 202.
  • Available clearance shown as dimension "a" serves as needed margin for this requirement. In this embodiment for not obstructed rotation of the storage there should be some clearance on left and right sides of the movable object 102.
  • FIG 6A- 6 E are schematic representations 100 illustrating an operations of the storage with outside joints of the four link mechanism moved back on the stationary plate in accordance with one embodiment of the present invention.
  • FIG 6A shows, in one embodiment, the locations of points A and D representing revolute joints 310 and 312, which are moved back on stationary base 202. Locations of revolute joins B and C are shifted left (as shown in FIG 6A) on bottom plate 104. Line BC remains perpendicular to AD on starting position.
  • FIGS 6B - 6D show transitional rotation of plate 104 in steps of 45° to a position shown in FIG 6E in which plate 104 is in 180° reversed position relative to starting position of FIG 6A.
  • This embodiment shows that in transitional positions especially close to position as shown in FIG 6C points B and C are not moved so much forward as shown in FIG 5C.
  • stationary plate 202 that supports wheels 350 and 352 (see FIG IF) located generally under the revolute joints B and C does not need to extend much forward,, it can be smaller.
  • this variation of present invention saves space in front of the storage for transitional positions of the storage and can be more stable against tip-over.
  • FIG 6A shows joints A and D, B and C that are located at positions that allow some uniformity with the other drawings but for optimization of each particular embodiment locations of these joints could be changed.
  • joints -A, D shown in FIG 6A could be moved more apart from each other to allow even better clearance than shown on FIG 6C.
  • FIG 7A- 7E are schematic representations 700 illustrating operations of the storage with outside joints of the four link mechanism located in diagonal comers of the stationary plate in accordance with one embodiment of the present invention-
  • joints A and D as shown in FIG 7A are located at diagonal comers of stationary plate 7202-
  • Joints B and C are located on the bottom plate 7104 approximately in the middle areas of its front and back sides at positions on different sides of the line AD and line BC in starting position as shown in FIG 7A is perpendicular to line AD.
  • FIGS 7B - 7D show transitional rotation of plate 7104 in steps of 45° to position shown in FIG 7E where plate 7104 is in 180° reversed position relative to starting position of FIG 7A.
  • One of the most important advantages of this embodiment is that during rotation for 180° in all transitional positions the movable storage generally does not need clearance or additional space for rotation. This is because during rotation of the storage its transitional positions are shifted away from the generally short side, particularly the side where one of the joints A and D is moved forward. The left side as shown in FIG 7A does not need extra clearance.
  • One of the applications when this advantage can be realized is when two storage cabinets are located side by side next to each other as shown in FIGS 9A - 9C.

  • stationary plate 8202 is larger than bottom plate 8104.
  • Joints A and D are located at remote diagonal locations of the stationary plate 8202.
  • B and C joints are located at positions of bottom plate 8104 generally symmetrically to the center point O of the line AD in a such way that line BC forms 45° angle with the line AD.

  • obstacles 8220 and 8222 are shown on back and right sides of the storage. They can be walls, barriers, other similar cabinets, etc.
  • final access position as shown in FIG 8E bottom plate 104 has labels marking all four sides as viewed from starting position.
  • a storage structure may be organized into front and backsides (as shown in FIG 8A) for holding articles. Left and right sides are blank. Only front side as shown in FIG 8A has access to its articles and backside is blocked from accessing to articles by wall 8220. After storage rotation by 90° clockwise to position as shown in FIG 8E "front" labeled side has no access because it is blocked by wall 8222. "Back" labeled side is open for access from the right side. [0085] Second example of storage structure is that only front side has developed storage structure for holding essential articles while other three sides could be just blank walls. Then rotation of storage by 90° will block access to storage completely- Rotation of the storage back to starting position will open front side again for access.
  • FIG 9A-9B are diagrams 900-920 illustrating a storage designed for light loads mounted on a desk with rotaxial designed illustrated in FIG 8A-8E.
