Definitions
- the invention relates to a laboratory shaker drive mechanism including a pair of flexible
- Patent 5,593,228 issued on January 14, 1997 and entitled "ROTARY SHAKER WITH
- Devices other than laboratory shakers also include flexible or reciprocating motion
- That device includes a drive mechanism for
- animal feed bowls is driven by a single shaft through two pairs of flexible straps.
- the invention comprises a laboratory shaker which includes a platform
- a frame including a pair of upright supports, also supports a drive motor.
- Each of the upright supports is attached to the outside surface of a flexible strap or belt.
- the drive motor causes the platform to move only in a single
- Fig. 1 is a front perspective view of the flexible band reciprocating shaker platform invention according to the preferred embodiment thereof.
- Fig. 2A is a perspective view of the flexible band reciprocating shaker platform
- Fig. 2B is an exploded view of the flexible band reciprocating shaker platform.
- Fig. 3 is a top plan view of the shaker platform with the tray and chassis removed.
- Fig. 4 is a side elevational view of the platform mechanism with the tray and chassis
- Fig. 5 is a front elevational view of the platform with the tray and chassis removed.
- Fig 6A illustrates the shaker platform in its fully reversed mode.
- Fig 6B illustrates the platform in its central, or neutral, position between the positions
- Fig 6C illustrates the shaker platform in its fully forward mode.
- the preferred embodiment of the invention 10 is illustrated in an assembled perspective
- Invention 10 includes a reciprocating platform 12, that only moves in a forward and backward direction, i.e., 1 dimension, not 2 dimensions, which supports a tray 14 which in
- a chassis cover 18 which supports a plurality of laboratory flasks 16 or Petri dishes or the like.
- Chassis 18 also supports a control panel 20 which may include a key pad 56 for
- a control panel 20 could typically include a speed indicator
- Power is provided to an electric drive motor 62 and the control panel
- invention 10 is similar to that of other prior art laboratory devices.
- Figs. 2A to 5 which represent counter-respectively orthogonal views of the drive mechanism.
- Invention 10 is supported by a frame 24 which includes a base 26 and a pair of upright supports
- Base 26 would also typically support the electric drive motor 62. Electric drive motor 62
- crank is preferably connected to the underside of the platform 12 through a conventional crank
- crank mechanism 54 A number of well known crank mechanisms, previously used in the art, would be
- crank mechanism 54 illustrated in the drawings and
- crank mechanism 52 would allow for adjustable stroke
- the pair of upright supports 28 each includes an inward facing surface 64. The inward
- facing surfaces 64 are attached by at least two pair of attachment means, such as bolts, rivets,
- Belts 30 and 32 are preferably fabricated from
- polyethylene or could be made from any other suitable, flexible, but not especially elastic
- belts 30 and 32 can be varied in thickness, width and length to
- belts 30 and 32 can actually be
- the first flexible belt 30 includes a pair of rollers 34 and 36 located on the inside thereof,
- rollers 34 and 36 respectively
- roller/belt attachments 44 which could comprise nails, machine
- rollers 38 and 40 are attached to the second flexible belt 32 by a suitable roller/belt attachment such as wood screws, machine screws, bolts, rivets, etc. 44.
- 40 can be made of any suitable durable, nonelastic material, such as wood, metal or plastic.
- support/belt attachments 46 which again, might comprise common fasteners such as wood
- supports 28 were made of thin gauge metal, then sheet metal screws, bolts or rivets might be
- the reciprocating motion of the drive mechanism is illustrated in a progressive fashion
- Fig. 6A the platform 12 is shown in its most withdrawn, i.e., reversed, position with
- rollers 34, 36, 38 and 40 have rotated approximately 60 degrees
- roller/belt fastener 44 are almost adjacent to the downward facing portions 70 of
- rollers 34, 36, 38 and 40 which in turn ride against the inside surfaces of the two upright supports
- the platform 12 is effectively equi-distance between the front 66 and back 68 of the base 26.
- the roller/belt attachments 44 effectively face directly forward and backward respectively.
- crank mechanism 54 has advanced to its other extreme
- roller/belt attachment means 44 almost come into contact with the pair of upward supports 28.
- the invention 10 just described has several advantages over the prior art.
- rollers 34, 36, 38 and 40 move across flat surfaces separated only by the
- the motion of the platform 12 is smooth, and not erratic.
- the mechanism is very sturdy and dependable. This means that it has a long life, especially under adverse conditions.
- the mechanism 10 is nearly noise free as compared to like devices using ball or
- a quiet running machine such as the present invention 10 is very desirable.
- length of the larger platform can be increased by making the roller diameters larger.
- the system can be provided to the public at a relatively reasonable and competitive
