The present invention generally relates to parking post. In particular, the invention relates to parking post capable of assuming retracted and protracted conformations and a mechanism therefor.
It is disclosed that the pertinent state-of-the-art is represented by U.S. Pat. No. 3,451,164, U.S. Pat. No. 3,698,135 and U.S. Pat. No. 5,961,249; GB patent applications GB2305199A, GB2346642A and GB2435669A as well as by international patent application having publication number WO1998/024979.
The present invention will be understood and appreciated more comprehensively from the following detailed description taken in conjunction with the appended drawings in which:
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention.
Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
In accordance with some embodiments of the parking post of present invention reference is now made to
Pedestal moiety 12 is covered by an enclosure of plates 14. Pedestal moiety 12 is formed by top and bottom frames 18 and 16, respectively. Top frame 18 is connected housing 27. Ribs 25 extend from housing 27. Ribs 25 interconnect between housing 27 and enclosure plates 14. Enclosure plates 14 are typically welded to each other at about 90 degrees angle as well as to ribs 25 at about 45 degrees angle. Housing 27 is used as the guiding rail for post moiety 20; conferring the latter a translation an essentially paralleling to the former.
A plurality of rollers 28 are disposed in-between housing 27 and post 20; preferably four rollers 28 are disposed on each interior face housing 27 facing vis-à-vis post 20. Rollers 28 are preferably affixed to the interior faces housing 27 facing vis-à-vis post 20. Rollers 28 are implemented to facilitate a smooth continuous translation of post 20 relatively to housing 27.
The mechanism of the parking post comprises plummets 40A and 40B. Plummet 40A is connected to string 42A, whereas plummet 40B is connected to a respective string (not shown), from the opposite (back) side of housing 27. String 42A is threaded onto pulley 41A, whereas string the aforesaid respective string (not shown), is threaded onto another pulley (not shown), from the opposite (back) side of housing 27. In
String 42A and the counterpart string are then drawn form said pulley 41A and counterpart pulley, respectively, downwards to jogs 46A and 46B of post 20; thereby essentially counterbalancing the weight of post 20 by the weight of plummets 40A and 40B, from both sides of post 20. Guiding strings 48A and 48B are threaded into apertures in or arcuate/annular on the surface of plummets 40A and 40B; thereby facilitating a continuous alignment during the vertical translation thereof, essentially paralleling post 20.
The collective weight of plummets 40A and 40B is typically predefined to somewhat exceed the weight of post 20; whereby the mechanism of the parking post spontaneously assumes protracted conformation 10B, wherein plummets 40A and 40B assume a lower position, shown in
Actuation pedal 30, which is used to secure the mechanism of the parking post in retracted and protracted conformations 10A and 10B, is pivotally connected to top frame 18. Pedal 30 is furnished with safety-catch 32, preventing unintentional actuation pedal 30. Slanted element 34, having an elongated oval aperture therein, is affixed to the bottom face of pedal 30. Pin 36 is threaded into the elongated oval aperture of slanted element 34. Pin 36 is connected to striker 38, which is inserted through a respective aperture in housing 27 into apertures 21A and 21B in post 20, respectively, in retracted and protracted conformations 10A and 10B. Upon application of force to pedal 30 in the direction towards the bottom, slanted element 34 is translated somewhat top towards bottom frame 16 thereby the oval aperture therein retracts striker 38 from pin 36 away from post 20, driving striker 38 out of apertures 21A and 21B in post 20, respectively, in retracted and protracted conformations 10A and 10B.
The mechanism of the parking post further comprises electrical motor 50. Electrical motor 50 is rotationally coupled to a gear, preferably of a planetary type. The rotor of the gear terminates with reel/sprocket 52. Belt/chain 54 is wound onto reel/sprocket 52 and reel/sprocket 58, mounted onto jog 59 of bottom frame 16. Jog 56 of post 20 is operationally connected belt/chain 54; thereby upon rotation reels/sprockets 52 and 58, belt/chain 54 is translated together with jog 56 thus retracting and protracting post 20. Motor 50 is coupled to an electric circuitry, including an energy source, preferably of a portable type, e.g. electrical battery, and a control module. The control module is connected to two microswitches disposed on jog 59 of bottom frame 16 and housing 27. Upon a contact with jog 56 of post 20 with the microswitches the operation of motor 50 is terminated. The control module comprises a remote control sub-module, which can be operated by a respective remote; thereby the parking post of the invention can be in retracted/protracted without any application of manual force, namely without leaving the vehicle.
The mechanism of the parking post further comprises locking mechanism 60, adapted to secure post 20 in protracted conformation 10B. Locking mechanism 60 comprises cylinder 62, wherein the driving element is a sprocket furnished with cogs 65. Cylinder 62 is a standard door-lock key-cylinder known in the art, such as the Euro Profile Cylinder available from Mul-T-Lock Technologies Ltd., Yavne 81104, Israel. Yoke 63 comprises an arcuate portion furnished with respective cogs 64; whereby upon rotation of cylinder 62 arcuate portion furnished with respective cogs 64 is translated along the sprocket furnished of the former. Yoke 63 is pivotally mounted on pivot 66 that is affixed in protrusion 67. The terminal portion of yoke 63, distant from cylinder 62, is pivotally connected to pivot 68 that affixed to striker 70. Striker 70 is inserted into aperture 23 in post 20. Circumferential ridge 69 is used to position striker 70 substantially perpendicularly to the face of post 20 with aperture 23 therein.
Upon a counterclockwise rotation of cylinder 62, striker 70 is retracted towards the interior of post 20; whereas upon a clockwise rotation of cylinder 62, striker 70 is protracted away from post 20 and can be inserted into aperture 61 within housing 27 in protracted conformation 10B; thereby locking post 20 in protracted conformation 10B.
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described herein above. Rather the scope of the invention is defined by the claims which follow:
