Definitions

  • the present invention relates to a disappearing post.
  • posts which can be used in order to bound parking places for prevent the access to ways and routes, even for temporary purposes only.
  • many times such areas have to be closed or bounded only during a determined time period during the day, in order not to be obliged to completely remove the boundary elements ("posts"), the need exists of having available movable posts which can be removed when necessary.
  • the posts of known type customarely used due to the above reason, of disappearing type, are arranged within holes excavated under the way and in the ground and can be actuated by means of either electrical or mechanical systems.
  • the posts are so lifted as to protrude above the ground or the way, in order to prevent the way or the parking site from being accessed by unauthorized vehicles.
  • the mechanically or hand actuatable posts display, at their top end, a suitable handle element by means of which said post is lifted and then blocked in such a lifted position, for example by being rotated around its axis.
  • the handle element is released and thereafter the post is re-entered into its casing.
  • a general drawback connected with all of the above post types is due to their poor visibility at night time and in the case of bad weather, and even their non-immediate visibility during their lifting or sinking step at prefixed times, in the absence of other signalling devices.
  • a purpose of the present finding is of providing a disappearing post which overcomes the above disclosed drawbacks.
  • Another purpose is also of building a simply installed, easily used post.
  • An important, not least, purpose of providing a post according to the present finding is also of minimizing its total overall dimensions inside the ground or in the site inside which said post is installed, with, however, the posts being made completely independent from each other.
  • a disappearing post which is suitable for being housed inside a hole excavated in the ground, comprising an external cylindrical element which acts as the true post, liftable and sinkable through a relevant actuator, both said post and said actuator being housed inside an external casing designed to be installed inside said excavated hole, characterized in that said actuator is completely contained inside said external cylindrical element, with a signalling unit being furthermore provided inside a top cover element for the external cylindrical element.
  • the disappearing post (11) is generally essentially housed inside an external housing (12), partially shown, suitable for being housed inside a hole excavated in the ground.
  • the post (11), as shown in Figure 1, comprises a central hollow column (13) fastened onto the bottom of the external housing (12), on which an external cylindrical element (14) which acts as the true post, is slidingly guided.
  • the external element (14) slides along the external surface of the hole column (13) thanks to the presence of bearing-type elements (15) provided at its bottom open region.
  • the motion during such a lifting/sinking movement is supplied by a motor means (10) interacting, through a first gear means (16) keyed to it, with a second gear means (17) made integral with a screw-threaded shaft, or screw (18) which, by running through a hole (19) provided through a support plate (20) integrally arranged transversely to the external element (14), enters a nut screw (21) fastened to the top end of said hollow column (13).
  • the motor means (15) is facing downwards and during the post movement enters between the external cylindrical (14) and the stationary hollow column (13) inside windows (22) and (23) respectively provided through the support plate (20) and the top end wall (9) of the hollow column (13).
  • a signalling unit inside a top closure portion (24) of this external cylindrical element (14), a signalling unit, indicated with (25), is installed.
  • a signalling unit (25) can be made with lighting elements schematically shown in (26), but which can be positioned in a whatever desired way.
  • the same lighting elements (26) can be, e.g., one single flashing lamp, or a plurality of differentiated light signals for signalling that the disappearing post according to the present invention has been lifted, has been lowered, or is stably positioned in its lifted position.
  • the control of the lighting elements (26) is provided by an electrical-electronic central unit (27) which is arranged inside the top closure portion (24).
  • sound signal generating elements such as sound warning elements, schematically shown in (28), can be stably housed, which signal the possible changes in position of post (11).
  • Figure 2 displays a second exemplifying embodiment of the disappearing post in which same elements are indicated by means of same reference numerals.
  • an actuator element of oil-dynamic type such as a cylinder integrally connected with the interior of the external casing (12), at its bottom end, is provided.
  • the free end (30) of the stem of said cylinder is fastened, on the contrary, to the support plate (20), which it moves upwards during its extension or lifting step.
  • the stem of the cylinder (29) is constituted by two mutually coaxial portion (31), (32), with the innermost portion (31) having the free end (30) which gets engaged with the support plate (20).
  • the external hollow cylindrical element is indicated with (14), and one may observe that coaxially with, and inside, it, a second external cylindrical, also hollow, element (33) is provided. Both hollow cylindrical elements (14) and (33) are prevented from rotating relatively to each other by a stud (34) which is fastened onto the support plate (20), and extends downwards running through a bore (35) provided through a top closure plate (36) of the second external cylindrical element (33).
  • actuating the oil-dynamic cylinder (29) promotes, first of all, the extension outwards of the telescopic portion of stem (31), with the external hollow cylindrical element (14) being lifted. Then, when the first portion of stem (31) is completely extended outwards, also said second portion of stem (32) starts to extend. Said second stem portion (32) engages the closure plate (36) and moves upwards also said second external cylindrical element (33).
  • a signalling unit is installed, with lighting elements (26) which, as already said, can be positioned in a whatever way.
  • the control of the lighting elements (26) is supplied by an electrical-electronic central unit (27) arranged inside the top closure portion (24), inside which the above mentioned sound warning elements (28) can be housed.
  • Figure 3 illustrates a further possible exemplifying embodiment of disappearing post according to the present invention.
  • This exemplifying embodiment is a particularly compact one, because it contains all the necessary equipment for disappearing post operations.
  • an oil-dynamic actuator (37) is installed in upside down position, i. e., with an end of its stem (38) being constrained to a central support column (39) made integral with the external casing (12).
  • the base of the cylinder (37) is constrained, on the contrary, to the support plane (20), by running through a central bore (40) provided through the top closure plate (36) of the second external cylindrical element (33).
  • studs (34), e.g. three of them, are provided which, on the one side, are constrained to the support plate (20), and extend downwards running through holes (35) provided through the top closure plate (36) of the second external cylindrical element (33).
  • the studs (34) are provided with engagement elements (41) which get engaged with the top closure plate (36), which implies that the second external cylindrical element (33) will be dragged upwards.
  • the central cylinder (37) is fed by means of suitable ducts (42) controlled by means of solenoid valves (43) and a pump (44) driven by motor means (45). Associated with this system, also a tank (46) is provided. All these elements which constitute the oil-dynamic system are contained inside a chamber (47), or are anyway supported above the support plate (40). The chamber (47) is closed by sealing elements (48) which also cooperate to enable the second external cylindrical element (33) to slide along the central support column (39).
  • a signalling unit is installed which is indicated with (25), which is provided with lighting element (26), which, as already said, can be positioned in any desired way.
  • the lighting elements (26) are controlled by an electrical-electronic central unit (27) installed inside the top closure portion (24), in which the above said sound warning elements (28) can be housed.
  • This third exemplifying embodiment results to be particularly compact and advantageous as regards the extremely small overall dimensions, and the maintenance thereof, which is only carried out on elements contained inside the post.
  • Figure 4 displays a further example of disappearing post in which the external hollow cylindrical element (14) is of increased thickness and is such as to get supported in kerbstone fashion in its retracted resting position, on a base portion (60) having its identical outline.
  • the external portion supports the load which is transmitted to it by the top closure element (24).
  • the post is constructed in compliance of the applicable European regulations, and in order to support loads of up to 90 tons.
  • a central oil-dynamic cylinder (61) with rotation preventing guide studs (62) is provided inside the top closure element (24), of cap type.
  • a central seat (63) is provided for housing lamps (64), well visible also in the presence of sun light, to which a transparent element (65) is super imposed.
  • Figure 5 displays a still further exemplifying embodiment of disappearing post in which inside the external hollow cylindrical element (14), an oil-dynamic unit (66) with its relevant tank (67), and an electrical-electronic central unit (68) which pilots the several drive means, are installed.
  • One single cylinder (69) which extends from a base (70) drives the post lifting/sinking.
  • the structure is particularly compact and strong, of mushroom type, which, inside the top closure element (24), is perimetrically provided, on its side surface, with a seat (72) which houses a transparent ring (71) and inside which a set of lamps (64) are arranged, well visible also in the presence of sun light, and which may be either flashing, or kept continuously lit.
  • a post according to the present invention can be provided with electrical power, water, air, telephone taps and power supply lines in general.
