Abstract
ABSTRACT OF THE DISCLOSURE
A road barricade (22) can be swivelled upward from its open position parallel to the road surface, in which its U-shaped cross-section overarches the drive mechanism, about a shaft (20) secured to the ground, into barricade position. To this end it has, on the side nearer the ground in the open position, a pair of guide curves (82, 83), or a pair of rectilinear guide ramps (27, 29) along which a pair of feed rollers (36,38) move, which are mounted on a threaded muff (34) which slides on a drive spindle (30). This drive spindle is guided by means of running wheels (44, 46) on the base plate (14) of the barrier and carries a protective tube (50, 56) which surrounds the spindle (30). In an approximately vertical closed position, the common shaft butt ends of the feed rollers and the running wheels engage in curved grooves (74) in the barricade element; the barricade element is swivelled downward in a controlled manner under it own weight by the co-operation of the guide lines with the feed rollers. At least the free end region of the barricade element can be flexible, and at least the drive region can be heatable.

Description
Description Road barricade The invention relates to a road barricade, in particular a car pa:rk barricade, that is fastened to the road surface and that has a barricade element optionally positionable parallel to the road surface or in a position at an angle thereto, said barricade element being swivellable upwards about an axis parallel to the road surface and vertical to the blocking direction by means of a drive mechanism com-prising a spindle element.
A corr2sponding barricade ~`or car pa~ks ls known from German patent DE-U-8 708065. Along a spindle element fixed on the road surface is moved a threaded bush from which extends a plate cannec-ted by an articulated joint to the barricade element for swivelling the barricade element by moving the sleeve. The barricade element is swivelled up and down by a forced drive mechanism.
.~
The object of the present invention is to develop a road barricade of the type described above such that automatic blocking and opening of the road surface can be achieved with simple design means. It should also ~e ensured that the risk of injury is ruled out, particularly contusions when the barricade is swivelled up into the non-blocking WO 90/09487 ,~ a~ F$~:P9o/oo233 position. Furthermore, the drive mechanism and the spindle element must be accessible even when the drive mechanism, for example, is out of order, thus permitting maintenance and repair work.
The object is substantially attained in accordance with the invention in that the barricade element has, facing away from the road surface, at least one feed line/curve along which an adjustable sliding element can move for swivelling the barricade element. The distance between the feed line/curve and the road surface, seen from the rotary a~is of the barricade element, can increase towards its free end or initially decrease and then increase.
The curve path of the feed line last described follows a geometry similar to a curve with a minimum in the area of the road surface. As a result~ an even swivel upwards and downwards of the barricade element is assured. Equal swivel angles can be covered in the same units of time.
Accordingly, it is possible with simple design means to swivel the barricade element upwards, with the downward swivel being assured by gravity. This return swivel motion is not however an abrupt one; there is a delaying effect caused by the interaction of the feed line/curve and the returning sliding element. As a result, the risk of con-tusions from downward swivelling of the barricade element is ruled out.
The drive mechanism prefera~ly operates the spindle ele-ment, such as a recirculating ball screw, that is parallel !~ to the road surface and covered by the barricade element when the latter is parallel to the road surface, by means of which element a sliding block or roller carrier con-taining the sliding element is movable. Feed wheels can extend from the sliding element that interact with the feed line/curve to swivel the barricade element.
WO 90/09~87 PCT/EP90~00233 , ,. ~', ,; ~i J
To protect the drive mechanism, which can be an electric motor, known from small power tools such as drills, for example~ a slipping clutch can be provided between the spindle element and the drive mechanism itself.
, , .
A gearbox is preferably connected between an electric motor and the spindle or element having thP same effect, in order to permit setting of a desired swivelling speed.
In addition, the motor can be switched o~f by means of a current limiter, i.e. the voltage supply is interrupted when the motor draws too much current.
Two feed lines/curves symmetrical to the longitudinal axis of the spindle element are preferably provided that are formed by the edges of flanges which in their turn are provided with a cladding to form the barricade element.
The flanges themselves are passed -through by the rotary axls or s~aft, so that a cladding material can accordinqly be selected that is quite thin. The cladding can be U-shaped in section.
It i5 also possible to design at least the free end of the barricade element flexible, for example by spiral element sections.
The sliding block passed through by the spindle element runs in controlled manner in the base plate. For this purpose, running wheels can extend from the sliding block that are guided laterally along or on raised sections extending from the base plate.
`~3 In order both to protect the spindle element such as a re-circulating ball screw and to rule out any risk of injury when operating the spindles, it is furthermore provided that a protective tube extends from the sliding block to surround the free end of the spindle element. ~o protect the spindle element between the sliding block and the drive mechanism, a hellows-type hose that can extend Wo 90/09487 PCT/EP90/00233 between the sliding block and a bearing can be provided to hold the spindle.
Alternatively, the spindle can be inside a tube that is in ~, its turn rigidly connected to the sliding element or roller carrier. In this case, the tube extending beyond the sliding block can be dispensed with.
Further details, advantages and features of the invention can be found not only in the claims and in the features stated therein - singly and/or in combination - but also in the following description of an embodiment shown in the drawings.

Fi~. 1 shows a barricade (10) in accordance with the invention that is fastened directly to a road surface such as a parking surface (12) in order to block or open the latter to the extent required. The barricade (10) has a base plate (14) connected to the road surface by bolts, for example. Side pieces (16) and (18) project from the base plate (14) and have passing through them a shaft (20) about which a barricade element (22) such as a post or bollard can be swivelled.
The barricade element (22) comprises a cladding (24) of preferably U-shaped section open towards the parking surface (12). From the inner surface, preferably ~rom the inner surface parallel to the parking surface (12) shown in Fig. 1, flanges (26) and (2~) vertical to the base plate (14) extend that in their turn have a shaft (20) passing through them and are swivellable about said shaft.
The flanges (26) and (28) can also be part of a U-shaped element open towards the base plate (14) and projecting from the cladding (24).
The flanges (26) and (28) each have a ramp-shaped feed line (27) and (29) using which the element (22) is swivelled in the manner des~_ribed below.
., Parallel to the base plate (14) and centrally between the side plates (16), (18) and flanges (26), (28) is a recir-culating ball screw (30) supported by a bearing (32) and holding a sliding block (34). ~urning the spindle (30) therefore moves the sliding block (34) axially.
Since feed rollers (36) and (38) interacting with the feed lines formed by the lower edges (40) and (42) of legs (26) and (28) extend from the sliding block (3~), it is accord-ingly possible to raise the barricade element (22) by moving the sliding block (34) in the direction of the shaft (20~. To do so, the recirculating ball screw (30) is connected preferably via a slipping clutch ~44) to an Wo 90/09~87 PCT/EP90/00233 electric motor (58) that can be of a type known from small power tools such as drills. The drive mechanism can be activated by remote control, switches or the like.
The barricade element (22) is, in the projecting position, preferably at a slight angle to ensure gravity lowering of the element when the sliding block (34) is moved back.
This however ensures that abrupt lowering, which harbours the risk of contusion, is prevented, since only a gradual downward motion is possible given the distance of the sliding block (34) from the shaft (20) thanks to the interaction of the feed lines (27) and (29) with the feed rollers (36) and (38).
For guidance of the sliding bloG~ to the required extent, - it has running wheels (44) and (46) that run laterally on a raised section (48) extending from the base plate (14).
The front free end of the spindle (30) is surrounded by a protective tube (50) extendinq from the sliding block (34). The area between the bearing (32) and the sliding block (34) can in its turn be protected by a bellows-type hose, not illustrated.
The cladding (24) is rectangular and open towards the base plate (14). In the front sloped end (S2), a supporting element (54) is provided that can be rested on the base plate (14).
It is also possible to design at least the free end of the barricade element (22) flexi~le in order to avoid damage yr~l to a motor vehicle should the barricade (10) be driven over while in the blocking position.
Figs. 4 and 5 are preferred embodiments of a barricade with the same design and function principle as the barricade (10).
Wo 90/094O7 PCT/EPsO/00233 7 J '. ~
The embodiments in Figs. 4 and 5 differ however from those in Figs. 1 to 3 in that the sliding block, which is also designated as roller carrier (3~), is firmly connected to a mounting such as a tube (56), in which the recirculating ball screw, not illustrated, is rotatably disposed. As a result, the tube (56) more or less surrounds the recircu-lating ball screw, depending on whether the sliding block (34) is in the vicinity of the swivel axis (20~, i.e. when the barricade element is raised, or in the returned posi-tion, in which the barricade element is resting on the base plate (14).
As Figs. 4 and 5 also make clear, an electric motor (58) is swivellably attached via a gearbox (60) to a shaft (62) '1 which in its turn extends from a mounting (64) attached to the base plate (14).
The motor (58) can be a 24 V motor with a current limiter~
As a result, a slipping clutch can be dispensed with. If an inadmissible force acts on the barricade element, the motor (58) would draw an inadmissibly large current. In this case, the current li~iter has the e~fect of inter-rupting the voltage supply to the electric motor (58).
To permit operation of the barricade in cold weather tool particularly in frosty conditions, heater elements in the form of foil heaters (66), (68) are provided in the area of the motor (58) and the gearbox (60) and can be operated by a thermostat.
Concerning the sliding block or roller carrier (3~), it ~i should be noted that the running wheels (44) and (46) are guided on raised rail-like sections (96) and (98). The feed rollers (36) and (38) interacting with the feed lines (27) and (29) are dis~osed on the outside.
The shaft passing through the feed rollers (36) and (38) and the wheels (44) and (46) has outward-projectin~ shaft WO 90/09487 ~ , CT/EP90/00233 butt ends (70) and (72) engaging ln curved grooves (74) preferably inside the side pieces (16) and (18) of the cladding (24). This enqagement of the butt ends (72) and (70) in the curved grooves (74) takes place just before the barricade post is swivelled into the vertical posi-tion. When the roller carrier (34) is moved back, the barricade post is accordingly moved too, but with the shaft ends (70) and (72) disengaging from the curved grooves (74), i.e. with the barricade post becoming - movable again once the gravity acting on it is sufficient to ensure automatic downward swivel of the barricade post.
~hese measures ensure that the risk of contusion as ruled out by the barricade in accordance with the invention is also ruled out when the barricade post is moveà into a vertical position.
Figs. 7 to la show particularly noteworthy embodiments of a barricade (80), with the same reference numbers being used for elements already described in connection with Figs. 1 to 6. It can also be seen from the sectional views that substantial elements of the embodiments o~ Fi~s. 4 to 6 are present in the barricade (80).
The main diEference between the barricade (80) and the barricade ~10) is the design of the ~eed curves inter-acting with the feed rollers, partially shown in a dashed line and numbered (82) in Fig. 7.
The feed curve ~82) rises, seen from the axis (20) in the i direction o~ the base plate (14), at first continuously ~section 84), and then follows a plateau (86) section by section that is parallel to the base plate (14) when the barricade element (22) is lowered. The feed curve (82) then falls continuously, i.e. the distance from the base plate (14) increases. This is made clear by the partly continuous line (88). ~round the end, a section (~0) can be discerned that is horizontal when the barricade element (82) is lowered and that interacts with the feed roller 9 ~ 3 (36) at the start, i.e. when the barricade element (22) is to be raised.
This path of the feed curve ( 82) ensures that equal swivel angles can be covered in the same units of time by the barricade element, so that an even raising and lowering of the barricade element (22) is achieved.
It can also be seen from Fig. 7 that the curved groove (74) is in sections approximately parallel to the curve section ( 84) of the feed curve ( 82).
The sectional views in Figs. 9 and 10 also show that the ; feed lines/curves (82), (83), are flanges of a U-shaped section open towards the base plate (14) attached to the inside of the cladding ( 24).
As the sectional view in Fig. 10 makes clear, the side walls of the barricade element (22) are reinforced in the area in which the shaft butt ends ~70) and t72) interact with the curved grooves (74),.
. 1 The cladding (24) itself can if necessary be broken off at preset breaking points - not described in detail - without damaging the mechanical drive mechanism. This measure may be necessary when, for example, the barricade element cannot be swivelled back for some reason although the barricaded surface must be completely accessible.
Concerning Fig. 7. it should further be mentioned that the area of the drive mechanism is covered with a U-shaped element (92) extending from the sliding block or roller carrier (3~). This protective element (92) is covered in its turn by a stationarily disposed protective element (94) extending from the holdinq means for the drive mechanism. These measures too ensure ln addition that the area of the drive mechanism is not freely accessible, so that a high degree of safety is assured.

The feed curve (82) then falls continuously, i.e. the distance from the base plate (14) increases. This is made clear by the partly continuous line (88). ~round the end, a section (~0) can be discerned that is horizontal when the barricade element (82) is lowered and that interacts with the feed roller 9 ~ 3 (36) at the start, i.e. when the barricade element (22) is to be raised.
This path of the feed curve ( 82) ensures that equal swivel angles can be covered in the same units of time by the barricade element, so that an even raising and lowering of the barricade element (22) is achieved.
It can also be seen from Fig. 7 that the curved groove (74) is in sections approximately parallel to the curve section ( 84) of the feed curve ( 82).
The sectional views in Figs. 9 and 10 also show that the ; feed lines/curves (82), (83), are flanges of a U-shaped section open towards the base plate (14) attached to the inside of the cladding ( 24).
As the sectional view in Fig. 10 makes clear, the side walls of the barricade element (22) are reinforced in the area in which the shaft butt ends ~70) and t72) interact with the curved grooves (74),.
. 1 The cladding (24) itself can if necessary be broken off at preset breaking points - not described in detail - without damaging the mechanical drive mechanism. This measure may be necessary when, for example, the barricade element cannot be swivelled back for some reason although the barricaded surface must be completely accessible.
Concerning Fig. 7. it should further be mentioned that the area of the drive mechanism is covered with a U-shaped element (92) extending from the sliding block or roller carrier (3~). This protective element (92) is covered in its turn by a stationarily disposed protective element (94) extending from the holdinq means for the drive mechanism. These measures too ensure ln addition that the area of the drive mechanism is not freely accessible, so that a high degree of safety is assured.
