DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
(52) Although the present disclosure will be described in connection with certain aspects and/or embodiments, it will be understood that the present disclosure is not limited to those particular aspects and/or embodiments. On the contrary, the present disclosure is intended to cover all alternatives, modifications, and equivalent arrangements as may be included within the spirit and scope of the present disclosure as defined by the appended claims.
(53) Referring to
(54) The candelabrum 10 includes a center of mass M.sub.1 (best shown in
(55) Referring to
(56) A center of mass M.sub.C1 of the combination of the candle 50 and the candle support 40 is designed to be lower than an axis of rotation R.sub.C1 or the pivot point of the candle support 40, which is at the location where the pivot portions 43a,b engage the pair of anchor beams 30a,b (see e.g.,
(57) The base 46 of the candle support 40 is coupled to the pair of arms 42a,b and is located below the pivot portions 43a,b that define the axis of rotation R.sub.C1 of the candle support 40. The center of mass of the arms 42a,b, the attachment portion 44, and the pivot portion 43a,b is also located below the pivot portion 43a,b. The center of mass of the candle support 40 is therefore located below the axis of rotation R.sub.C1 of the candle support 40. A candle 50 whose center of mass is lower than the pivot portion 43a,b can be placed into the base 46. The combination of the candle support 40 and the candle 50 has a center of mass M.sub.C1 that is located lower than the axis of rotation R.sub.C1, even as the candle burns away. The mass of the candle support 40 is usually negligible compared to an un-burnt candle 50. Thus, the position of the center of mass of the candle 50 dominates the location of the center of mass M.sub.C1 of the combination of the candle 50 and the candle support 40. A low center of mass M.sub.C1, relative to the axis of rotation R.sub.C1, increases the restoring force which returns the candle support 40 and candle 50 to the substantially vertical equilibrium position. That is, the lower the center of mass M.sub.C1, the faster the candle support 40 and candle 50 return to the substantially vertical equilibrium position after an external disturbance is removed from the candelabrum 10.
(58) The candelabrum 10 is designed such that the candle(s) 50 is/are biased to keep an upright (i.e., vertical) position when the candelabrum 10 is in the equilibrium position (
(59) Referring to
(60) The first anchor beam 30a includes a body 32a, a plurality of slots or apertures 34a, first and second ends 36a,b, and adjustment apertures 38. Similarly, the second anchor beam 30b includes a body 32b, a plurality of slots or apertures 34b, first and second ends 37a,b, and adjustment apertures 38. Each of the anchor beams 30a,b has a length that is substantially the same as the diameter of frame members 22a,b (shown and described below in reference to
(61) Adjustment of the vertical attachment position of the pair of anchor beams 30a,b shifts the center of mass M.sub.1 of the candelabrum 10, which results in varying responses when external disturbances are provided. For example, the lower the pair of anchor beams 30a,b is attached to the frame assembly 20, the lower the center of mass M.sub.1 of the candelabrum 10, which provides a relatively shorter response time (i.e., the candelabrum 10 returns to its equilibrium position (
(62) The pair of pivot portions 43a,b (
(63) The pair of anchor beams 30a,b is mounted to the frame assembly 20 as shown in
(64) Referring to
(65) As the frame members 22a,b are substantially circular, the frame assembly 20 itself is substantially circular, as shown from the front view (
(66) The frame assembly 20 and the pair of anchor beams 30a,b are shown as being separate parts; however, the frame assembly 20 and the pair of anchor beams 30a,b can be monolithic such that the height or vertical positioning of the pair of anchor beams 30a,b is fixed (i.e., not adjustable) within the frame assembly 20.
(67) The position of the pair of anchor beams 30a,b within the frame assembly 20 and the distribution of the candle supports 40 coupled to the pair of anchor beams 30a,b is adjustable such that the center of mass M.sub.1 of the candelabrum 10 can be adjusted vertically and/or horizontally. Positioning of the center of mass M.sub.1 below the axis of rotation R.sub.1 of the frame assembly 20 is desirable to maintain stability of the candelabrum 10, which is especially important when lit candles are placed in the candelabrum 10. The candelabrum 10 is in the stable equilibrium position (e.g.,
(68) The frame members 22a,b are shown in
(69) Referring to
(70) The candle supports 40 can be positioned at any point along the length of the pair of anchor beams 30a,b. For example, if more weight (i.e., more candle supports 40 and candles 50) is positioned on the right side of the pair of anchor beams 30a,b, then the center of mass M.sub.1 shifts to the right and the stable equilibrium position of the candelabrum 10 shifts accordingly and the frame assembly 20 rotates in the direction of arrow A (
(71) The candelabrum 10 has been described and shown in
(72) The candelabrum 100 includes a center of mass M.sub.2 that is below an axis of rotation R.sub.2 of the candelabrum 100. Such an arrangement of the center of mass M.sub.2 and the axis of rotation R.sub.2 means that the candelabrum 100 is in a state of stable equilibrium when the center of mass M.sub.2 is directly below the axis of rotation R.sub.2 as shown, for example, in
(73) Referring to
(74) The candelabrum 200 includes a center of mass M.sub.3 that is below an axis of rotation R.sub.3 of the candelabrum 200. Such an arrangement of the center of mass M.sub.3 and the axis of rotation R.sub.3 means that the candelabrum 200 in a state of stable equilibrium when the center of mass M.sub.3 is directly below the axis of rotation R.sub.3 as shown, for example, in
(75) Referring to
(76) The polygonal frame assembly 320 has a plurality of substantially flat or straight portions 323. Specifically, each frame member 322a,b of the frame assembly 320 includes a plurality of substantially flat portions 323. Each of the plurality of substantially flat portions 323 is configured to rest on a substantially flat surface, S, (e.g., a table). Depending on the distribution of the candle supports 340 along the length of the pair of anchor beams 330a,b, the candelabrum 300 can be at rest (i.e., a stable equilibrium position) while one of the flat portions 323 is in direct contact with a resting surface, S, (e.g., a table).
(77) The candelabrum 300 is in a stable equilibrium as long as its center of mass M.sub.4 lies between two imaginary lines 311. The two imaginary substantially vertical lines 311 emanate from the two ends of the substantially straight portion 323a in contact with the surface, S, on which the frame assembly 320 rests. The candelabrum 300 is in its stable equilibrium position as long as its center of mass M.sub.4 lies between the two imaginary dashed lines 311, which it does as the candle supports 340 are evenly distributed along the length of the pair of anchor beams 330a,b.
(78) Referring to
(79) The candelabrum 400 is in a stable equilibrium as long as its center of mass M.sub.5 lies between two imaginary lines 411. The two imaginary substantially vertical lines 411 emanate from the two points of adjacent portions 423 of the frame members 422a,b that are in direct contact with a resting surface, S, (e.g., a table) as shown in, for example,
(80) Referring to
(81) Referring to
(82) The candelabrum 600 includes a center of mass M.sub.6 that is below an axis of rotation R.sub.6 of the candelabrum 600. Such an arrangement of the center of mass M.sub.6 and the axis of rotation R.sub.6 means that the candelabrum 600 is in a state of stable equilibrium when the center of mass M.sub.6 is directly below the axis of rotation R.sub.6 as shown, for example, in
(83) Referring to
(84) The anchor grids 730a,b are attached to an outer surface of the frame assembly 720 via a weld connection, a glue connection, a screw connection, etc., or a combination thereof. To install, for example, the candle support 740a, the arms 742a,b of the candle support 740a can be pinched and/or squeezed together to provide sufficient clearance for the pivot portions 743a,b to be positioned through and between the anchor grids 730a,b and the frame assembly 720. Release of the arms 742a,b allows the candle support 740a to spring back into its unpinched shape thereby engaging the anchor grids 730a,b as shown in
(85) The candelabrum 700 includes a center of mass M.sub.7 that is below an axis of rotation R.sub.7 of the candelabrum 700. Such an arrangement of the center of mass M.sub.7 and the axis of rotation R.sub.7 means that the candelabrum 700 is in a state of stable equilibrium when the center of mass M.sub.7 is directly below the axis of rotation R.sub.7 as shown, for example, in
(86) Each of the first and the second frame members 722a,b defines an interior area, which is circular corresponding to the circular shape of the frame members 722a,b. The first one of the pair of anchor grids 730a is coupled to the first frame member 722a such that substantially all of the interior area defined by the first frame member 722a is covered by the first anchor grid 730a. Similarly, the second one of the pair of anchor grids 730b is coupled to the second frame member 722b such that substantially all of the interior area defined by the second frame member 722b is covered by the second anchor grid 730b.
(87) While the anchor grids 730a,b are shown and described as covering the entire side area of the frame assembly 720, it is contemplated that the anchor grids can cover only part of the sides of the frame assembly 720. Alternatively or additionally, a portion of the anchor grids 730a,b can extend beyond frame assembly 720 (not shown).
(88) Referring to
(89) The candelabrum 800 includes a center of mass M.sub.8 that is below an axis of rotation R.sub.8 of the candelabrum 800. Such an arrangement of the center of mass M.sub.8 and the axis of rotation R.sub.8 means that the candelabrum 800 is in a state of stable equilibrium when the center of mass M.sub.8 is directly below the axis of rotation R.sub.8 as shown, for example, in
(90) Referring to
(91) As shown in
(92) A center of mass M.sub.C2 of the combination of the candle 950 and the candle support 940 is designed to be lower than an axis of rotation R.sub.C2 or the pivot point of the candle support 940, which is similar to how the center of mass M.sub.C1 of the combination of the candle 950 and the candle support 940 is designed to be lower than the axis of rotation R.sub.C1 of the candle support 940. Such locations of the center of mass M.sub.C1 and M.sub.C2 aid in maintaining stability of each candle 950 when installed in the candelabrum 900.
(93) The position of the pair of anchor beams 930a,b in relation to the frame assembly 920 and the distribution of the candle supports 940 and the cantilevered candle supports 940 in relation to the pair of anchor beams 930a,b can be adjusted to move the center of mass M.sub.9 of the candelabrum 900 both vertically and horizontally. This center of mass M.sub.9 can be adjusted such that it is positioned horizontally (as viewed from the side view in
(94) Referring to
(95) The stoppers 1060 are attached to the frame members 1022a,b to aid in preventing the candelabrum from over-rotating during installation of one or more candles (not shown) and/or candle supports (not shown). For example, if one candle support is installed at the leftmost position of the anchor beams 1030a,b, the weight of the candle support and the candle therein would cause a shift in the center of mass of the candelabrum 1000 that would cause the candelabrum 1000 to rotate in the direction of arrow D. In some implementations, if the installed weight is large enough, the candelabrum can become unstable and tip over without the presence of the stoppers, which act to resist the over-rotation caused by the unevenly distributed load on the anchor beams 1030a,b. That is, the stoppers 1060 aid in preventing the candelabrum 1000 from tipping during installation of candle supports and/or candles.
(96) The frame members 1022a,b are generally symmetrical about a center of the candelabrum 1000. Alternatively, one of the frame members can be rotated 180 degrees as shown in
(97) Referring to
(98) The location of the stoppers 1060, 1160, and 1260 can be adjusted along the respective frame members to increase and/or decrease the amount of permitted rolling before the stopper aids in preventing further rolling. While two stoppers 1060 and 1160 are shown in
(99) Referring to
(100) The candelabrum 1300 includes a center of mass M.sub.10 that is on an axis of rotation R.sub.10 of the candelabrum 1300. Such an arrangement of the center of mass M.sub.10 and the axis of rotation R.sub.10 means that the candelabrum 1300 in a state of indifferent equilibrium. That is, the candelabrum 1300 is stable in all rotational positions (e.g., positions shown in
(101) The candelabrum 1300 is configured to be rolled by an external disturbance along a surface, S, without significantly disturbing the substantially vertical orientation of the candles 1350 included in the candle supports 1340. The rotation of the candelabrum 1300 in the direction of arrow B causes the candelabrum to translate in the direction of arrow C (i.e., the candelabrum rolls in the direction of arrow C when rotated in the direction of arrow B). For example, as shown in
(102) The candle supports 1340 are coupled to the pair of anchor beams 1330a,b at positions such that the candelabrum 1300 is free to rotate 360 degrees without the candle supports 1340 coming into contact with the surface, S, and without the adjacent candles 1350 coming into contact with each other and/or with the adjacent candle support 1340. While only two candles 1350 and two candle supports 1340 are shown, various other numbers and positions of candles 1350 and candle supports 1340 are possible. The dimensions of the candelabrum 1300 (i.e., the diameter of the frame assembly 1320, the length of the candles 1350, the length of the pair of anchor beams 1330) can be adjusted to accommodate a larger number of candles to avoid the candles 1350 and candle supports 1340 from contacting each other during rotation of the candelabrum 1300.
(103) Alternatively to the candelabrum 1300 including a pair of anchor beams 1330a,b, the candelabrum 1300 can include a pair of anchor grids (not shown), which is the same as, or similar to, the pair of anchor grids 730a,b described above and shown in
(104) The surface, S, upon which the candelabrum 1300 can be rotated can include one or more bearings (not shown) such that the candelabrum 1300 can rotate as described above but instead of translating along the surface, S, in the direction of arrow C, the candelabrum 1300 rotates in place on the one or more bearings. Additionally, the one or more bearings (not shown) can be motorized bearings such that a motor rotates or powers the bearings, which in turn causes the candelabrum 1300 to automatically rotate on the one or more bearings. The motor can be battery powered and/or plug-in powered and configured to receive AC and/or DC current. Additionally, the motorized bearings can further include a timer feature that is configured to activate at one or more preset times. For example, the timer feature can be programmed to turn on at 6 PM every Friday, automatically, such that the candelabrum is automatically rotated. The timer can be programmed to activate the motorized bearings for a predetermined amount of time, such as, for example, thirty minutes, one hour, two hours, twenty-four hours, etc.
(105) Each of the disclosed candelabrums is designed to support one or more candles. As the candles burn and melt, the distribution of the weight of the remaining portions of the installed candles will vary as candles typically do not burn and/or melt at a uniform rate. Additionally, because some candles will invariably be lit before others, the candles lit first will typically burn up or melt before the other candles lit afterwards. Such a lighting scheme can also cause various weight distributions to occur during the course of using the candelabrums of the present disclosure. These uneven distributions of weight across the various candelabrums of the present disclosure can result in a non-uniform rocking and/or rolling response of the frame assembly of the candelabrums. Specifically, as the weight distribution varies (due to candle melting), the center of gravity of the candelabrum can shift causing the frame assembly to roll and the installed candle supports will pivot accordingly as described herein to safely maintain a substantially vertical orientation for each of the candles that remain lit. The non-uniform rocking and/or rolling response of the frame assembly of the candelabrums also provides entertainment and excitement to one or more persons viewing the candelabrum in operation.
(106) While particular aspects, embodiments, and applications of the present disclosure have been illustrated and described, it is to be understood that the present disclosure is not limited to the precise construction and compositions disclosed herein and that various modifications, changes, and variations may be apparent from the foregoing descriptions without departing from the spirit and scope of the present disclosure as defined in the appended claims.
