FIELD OF INVENTION

[001] This invention relates to the Mechanism design and Enclosure, package design for various kinetic sculptures with provision for use as clock. This invention proposes an innovative way of designing and manufacturing the enclosure for kinetic sculptures, which is easy to manufacture and also decreases the material wastage. The present specification is based on and claims priority from an Indian Provisional application number 202041011058 filed on 14 ^th March 2020, the disclosure of which is incorporated herein.

BACKGROUND OF INVENTION

[002] Kinetic sculptures without enclosure are prone to tampering, dust, cobwebs, etc. Also, these kinetic sculptures can break during transportation.

[003] Hence there is a need to develop a compact, economical and robust packing solution for enclosing the Kinetic sculptures.

[004] Also existing clock designs come with static art, pictures.

[005] Hence there is a need to design clocks with dynamic art like Kinetic sculptures.

OBJECT OF INVENTION

[006] The principal object of this invention is to design kinetic sculpture mechanism, which enables the device to act as a clock , as well as display interesting moire patterns creating dynamic art.

[007] Another object of this invention is to design and manufacture the enclosure for kinetic sculptures, which thereby helps to prevent the kinetic sculptures from tampering, dust, cobwebs, etc. And also, helps in packing the kinetic sculptures effectively during transportation.

[008] These and other objects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating preferred embodiments and numerous specific details thereof, are given by way of illustration and not of limitation.

DETAILED DESCRIPTION OF INVENTION

[0013] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.

[0014] The embodiments herein describe the design and manufacturing of the enclosure for Moire kinetic sculptures, which thereby helps to prevent the kinetic sculptures from tampering, dust, cobwebs, etc. And also, helps in packing the kinetic sculptures effectively during transportation. Referring now to the drawings, and more particularly to FIGS. 1 through 3, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.

[0015] The moire kinetic art consists of two concentric rotating discs 101, 102 as shown in Figure 1 with specific design patterns cut on it. When the discs rotate at different velocities and direction relative to each other, different moire patterns, visual effects are produced. Figl shows a sample moire pattern design. Any other standard patterns capable of creating visual effects can also be used.

[0016] The manufacturing of the kinetic sculpture mechanism begins with cutting the rotating discs 101,102 in CNC machine, the left-over parts 103,104 and 108 while cutting the rotating discs 101,102 can be used as enclosure front and back plates during the final assembly. [0017] The locking plates 103, 108 are attached together with a small angular shift in rotation such that the structure is totally closed without any openings.

[0018] The gear driving mechanism 105 is locked to the plate 108, and then the rotating discs 101,102 are attached to the gear mechanism.

[0019] To close the front of the kinetic structure we use an acrylic plate 106 locked to 104 plate and these two plates are finally locked to the 103 plate using spacer rods 107.

[0020] To close the kinetic sculpture sideways, we can use any kind of chart paper or metal or plastic sheet 109 to wrap the sides of the enclosure.

[0021] The spacer rods 107 can be optionally aluminium extrusion profiles, to which the sheet 109 can be bolted using T-nuts.

[0022] In one embodiment, the motors driving the discs 101, 102 are two independent position-controlled motors (121, 122) like stepper or servo motors.

[0023] The motors also have home position sensors (133, 134) to know their absolute positions on power up.

[0024] Now the motors can function in two modes: as a clock or as a rotating mechanism producing moire visual patterns to the viewer.

[0025] The arm position of the back disc lOlcan show the minute position (clock long hand) and the arm position of the front disc 102 can show the hour position ( clock short hand ).

[0026] Periodically, the two discs can also spin at different speeds and directions relative to each other, producing interesting moire pattern visual effects to the user.

[0027] In one embodiment, one of the arm 101A or all the arms of the disc 101 are longer than the arms of the front disc 102.

[0028] A pointer (111) is attached to one arm 101A of the back disc 101, showing the minute of the clock time. [0029] A pointer (112) is attached to one arm 102A of the front disc 102, showing the hour of the clock time.

[0030] In one embodiment, an LED light 113 or LASER pointer 114 is attached to the arm 101A, to indicate the minute position

[0031] An LED light 113A or LASER pointer 114A is attached to the arm 102 A to indicate the hour position.

[0032] The front acrylic 106 has a semi-transparent ring 106A near the outer diameter, with markings for minute and hours of the clock.

[0033] The light from LED 113A or LASER pointer 114A falls on this semitransparent sheet 106A thus indicating clock time to the user.

[0034] Figure 3 shows the moire clock rotation mechanism in more detail. Stepper or servo motors 121, 122 are fixed to plate 133.

[0035] 121 is a hollow shaft motor.

[0036] 123 is a front shaft of motor 121.

[0037] 124 is rear shaft of motor 121.

[0038] Bushes 125, 126 are press fitted to the shafts 123, 124 as shown in fig 3.

[0039] 127 is another long shaft passing through the bushes 125, 126 in a sliding fit.

[0040] In one embodiment, the shaft 127 is also a hollow shaft, so that the cables to power the laser 114, 114A can pass through this hollow shaft.

[0041] Gear 128 locked to shaft 127 meshes or engages with gear 129 locked to shaft 130 of the motor 122.

[0042] Now the shafts 123, 127 can rotate independent of each other to any position or speed.

[0043] The discs 101, 102 are each locked to one of the two shafts 123, 127. [0044] In one embodiment, the gear drive 128, 129 can be replaced with other motion drive mechanisms like timer belt etc.

[0045] The plate 133 is locked by two or more bolts 131, 132 to the back plate 108.

[0046] In the same way, the Nautilus gear mechanism can be made by cutting the rotating discs 201,202 and the left-over material can be used as enclosure front plate 203.

[0047] The drawing for CNC cutting is designed such that the plate 203 is in the shape of INFINITY (2 circles next to each other, with the intersecting portions welded to form a single “infinity” shaped geometry, the inner radius of the plate 203 being slightly larger than outer radius of the rotating discs 201, 202). Such an enclosure shape design is very aesthetic and also utilizes minimum material to enclose the rotating gears.

[0048] The gear driving mechanism 207 is locked to the back plate 204, and then the rotating discs 201,202 are attached to the gear mechanism.

[0049] To close the front of the kinetic structure we use an acrylic plate 205 locked to 203 plate and these two plates are finally locked to the 204 back plate using spacer rods 206.

[0050] During transportation of these mechanism the rotating discs 101,102can be placed inside the plates 103,108 and in the same way the rotating discs 201,202can be placed inside the left-over plate 208.

[0051] A clock display unit is fixed inside the enclosure, so the kinetic sculpture can also act as a time display unit. The display can have smart watch features with internet connectivity to display other useful info beyond time.
