Description

Austrian Patent Office AT504 408B1 2012-03-15

Description: The invention relates to a height-adjustable support for raised floors, in particular for exhibitions, fairs, etc., with a foot for resting on the ground and a head on which the lining plates come to rest, with a foot and head connecting threaded rod, the Is rotatably mounted on the head, but axially non-displaceable and cooperates in the foot with a fixed therein provided mating thread, according to the introductory part of claim 1.

A similar support is known from DE 203 18 010 U. In this case, however, the threaded rod does not interact with a mating thread of the foot but with a thread of an adjustment sleeve rotatably mounted in the foot. This carries a toothing and is connected by means of a chain with a permanently mounted on the base plate pinion, which in turn can be rotated with a tool, whereby the head height is adjusted. This support is complex because of the mechanics, expensive and heavy and is also prone to contamination because of the exposed in the ground of the mechanics.

An older support the same applicant for a frame construction of a double bottom is disclosed in DE 93 05 581 U1: In this case, an adjusting sleeve with external thread is rotatably mounted on the foot, the head has a meshing internal thread, the interior of the adjusting sleeve carries a receptacle for a tool and is freely accessible, is also not covered by the frame. For surface-locked floors, this construction is completely unsuitable.

The US 2003/0025049 A1 discloses a support with a high foot with rotatable insert sleeve with internal thread, in which the head part is screwed with a screw and fixed by means of lock nut. The entire upper part is then oriented correctly with insert sleeve and fixed by means of a fixing screw. This system is not useful for frequent construction and dismantling, the lock nut is accessible only from one side and even then not easy to use. This is unpleasant especially when dismantling and especially for subsequent fine corrections prohibitive.

EP 1 247 922 A2 discloses a special top plate for supporting a double bottom, the support itself is shown only in FIG. 1 and substantially corresponds to the support according to US 2003/0025049 A1, thus also has the same disadvantages ,

WO 91/15641 A1 relates to a raised floor, in which each plate has a Eckausnehmung and is supported in each case by means of supports similar to the aforementioned in the area each corner. The four Eckausnehmungen form a circle with contoured edge, in which a closing and holding plate is used in the manner of a bayonet closure. This construction is also unsuitable for surface-engaging coverings.

Non-generic supports for furniture, especially for refrigerators, washing machines, printing tables, etc. are known from US 3,844,518 A, US 5,697,586 A and DE 29 03 835 A1. All these supports are unsuitable for floors, especially for surface-locked floors.

In the applications mentioned paving plates are each supported at their corners by a support whose foot rests on the ground and whose head, on which the lining plates are connected to the foot via a rotatable in the foot but axially fixed thread, said in Head a nut is provided firmly, which meshes with the thread and changes the height position when turning the thread. In order to adjust the height matching, a recess for an Allen wrench or the like is provided in the threaded rod at the upper end face and the lining plates are beveled at the corners or concave except to allow adjustment when applied lining plates. The recesses in the area of the threaded rod are finally closed with special filling pieces, but what is often annoying visually also makes a special fixation of these fasteners necessary. It is an object and object of the invention to provide a support of the type mentioned, can be used in the covering plates with corners, the actual, apart from joints, the floor interpret surface-locking and in the height adjustment even then can be easily performed when all are laid down to a covering plates in a support point.

These objects are achieved in a support of the type defined according to the characterizing part of claim 1, characterized in that with the threaded rod a handle is rotatably connected. Preferably, the handle is a gear with external thread. In this way, it is possible by hand or with a simple tool to turn the threaded rod even if all but one, with rectangular plates, already laid three of the four plates.

In one embodiment, four, preferably six or eight recesses are provided in the head and / or foot, in which a crank can be inserted with a suitably arranged pinion. Thus, the top plate can be formed over a large area and it is the tool well guided by the recesses.

Further embodiments are specified in the further subclaims.

The invention will be explained in more detail below with reference to the drawing. It shows the

Fig. 1 shows an adjustable support leg according to the prior art in a schematic side view with an equally schematic plan view of the formation of the lining plates in the support area, the

2 shows a first variant of the invention likewise in a schematic side view with representation of the lining plates in the support region, FIG. 3 shows a schematic view of a second variant, FIG. 4 shows a schematic side view of a third variant, FIG. 5 shows a fourth variant, Figs. 6, 7 and 8 show a further variant in different views and Fig. 9 shows a variant in four views.

1 shows the situation according to the prior art schematically. Plating plates 1 with concave recesses 7 in the region of their corners rest on the heads 4 of the adjustable supports 2. The heads 4 have in their central region nuts 8, whose internal thread meshes with the external thread of a threaded rod 5. The threaded rod 5 is rotatably but axially fixed in a foot 3 of the support 2, the foot 3 rests on the ground and is optionally connected to it.

At the upper end of the threaded rod 5, a device for rotating the threaded rod 5 is provided, this is preferably a recess for an Allen wrench, but other training is possible, the threaded rod may be ground to a hexagon and the like more.

Laying a floor covering in this prior art system, now carried out so that a first lining plate 1 is placed with each of its corners on a support 2, wherein projections or recesses on the upper surface of the head 4 and corresponding recesses or projections Make sure on the undersides of the lining plates 1 that after placing the lining plates turning the heads 4 about the threaded rod 5 is no longer possible without dislodging the lining plate from the head. Then, with a spirit level or similar aids, by turning the threaded rods 5, the lining plate brought into the correct height and in the horizontal. Thus, the four supporting columns 2 are positioned. The next plate is now placed on one of the sides and supported at its still free corners by two other supports 2. With the aid of a spirit level, these two supports or their heads can be positioned so that this second plate is also in the given plane. As the laying of panels progresses, more and more cases occur in which only one support per cover plate is newly added, and especially in these cases, but also in cases with two supports per covering plate would be an adjustment without recess of the corners of the covering plates not possible anymore.

2 to 5 show now purely schematically inventive solutions, each based on the fact that with the threaded rod 5, a handle 16, 26, 36, 46 is rotatably connected. In Fig. 2 is in this handle 16 simply by at least two, preferably four at a uniform angle of the threaded rod 5 radially projecting, rotatably connected with her rods, which optionally carry a button or the like at its free end for ease of grasping. Even if, as shown in the minor figure, already three cover plates 1 are launched, the free ends of the handle 16 protrude far enough in the remaining free quadrants below the head 4 in order to be detected there without problems and properly rotated. By this measure it is possible, as can be seen from the secondary figure, the lining plates 1 with "genuine". To provide corners.

Fig. 3 shows a variant in which the handle 26 consists of a rotatably connected to the threaded rod 5 gear 25 with spur toothing. At the appropriate distance from the axis of the threaded rod 5 at least four, preferably six or eight rifles or recess 24 are provided in the foot 4. In these cans or recesses, a tool, namely a crank 27 are rotatably inserted with its free end. The crank 27 carries at a suitable distance from its free end a pinion 28 having an external thread which meshes with the external thread of the gear 25.

In the illustrated variant, a sufficiently large recess is also provided in the head 4, which can be brought to escape with one of the bushings or recesses 24, and at the level of the crank 27 has a matching thickening 23, whose diameter is greater as the pinion, so that the crank 27 is guided twice and can be operated very easily. If the head 4 is not so large in its radial extension, this recess can be dispensed with, and the crank 27 is guided only at its lower, free end in the bush or recess 24.

Finally, Fig. 4 shows a variant in which the rack 5 is rotatably connected within the plate-shaped foot 3 with a ring gear 35. A tool 36 consists of a suitably formed bevel gear 38 which is rotatably disposed at the lower end of a crank 37. The crank 37 has, above the bevel gear 38, a guide 33 which is provided with a bearing or a recess 34, of which at least four, preferably six or eight, in suitable places in the oblique, conical surface of the foot 3, interacts. By simply inserting the crank 37 and turning the same, it is possible to rotate the threaded rod 5 and thus adjust the head 4 of the height.

A further embodiment is shown in FIG. 5. The serving as a support for the lining plates 1 head 4 has with respect to the axis of the threaded rod 5 and the imaginary point of contact of four lining plates at least one decentralized opening 39, which allows the insertion of a crank 40 with pinion 41 in a socket 44. In the inserted position of the crank, the pinion engages in the teeth of a gear 42, which in the upper region of the threaded rod 5, rotatably connected thereto, is seated. Even if - as shown in Fig. 5 - one or up to three lining plate (s) is already laid, due to the decentralized openings 39 by turning the crank, the height of the head 4 can be adjusted exactly. Of course, more than two openings 39 and aligned bushings 44 may be provided, preferably concentric about the axis of the threaded rod 5 and in each quarter at least one, so even with three already installed covering plates accessibility without prior consideration of the order of laying the covering plates given is.

6 to 8 show an embodiment in which by actuation of a decentralized shaft 43 in a trained as a base foot 3 rotatably mounted gear 48 is driven. A standing in engagement with this gear 48 second gear 45 drives a threaded spindle 47 which is screwed in a provided in the head 4 nut 46. 3/11 Austrian Patent Office AT504 408B1 2012-03-15

Upon actuation of the shaft 43, which has a receptacle for a screwdriver at its upper end, the threaded spindle 47 is rotated in the nut 46, whereby the head 4 raises or lowers relative to the base. At the same time prevents the decentralized shaft 43 (even with not laid covering plates) that the head 4 rotates with respect to the base.

It would also be conceivable, of course, that the gear 45 sets a nut in rotation, whereby a screwed into the nut rotatably connected to the head 4 threaded spindle performs a vertical movement.

In the example shown, a cruciform support plate 58 is provided between the actual head 4 and the (not shown) covering plates, the adjusting elements 49 and fixing elements 50 (which find their counter-elements on the underside correspondingly formed lining plates) and the easier laying of the lining plates to serve on the supports. The adjusting elements are used for easier positioning of the lining plates by an essentially positive connection. Once the correct position has been achieved by means of the adjusting elements (e.g., pins, nubs, etc.), the lining plate is frictionally connected to the support plate 58 by engagement with the fixing elements (e.g., notches, hooks, mushroom-shaped projections, etc.). In the example shown, the support plate 58 is fixed by nubs 51 on the head 4. Head and platen can also be integrally formed, also plays the shape of the head and platen no essential to the invention role.

Fig. 9 shows a variant of the last described embodiment, which also has similarities with the embodiment of FIG. 5, but with the fixed bearing 51 and the nut 52 have changed places. Compared to the variant of FIGS. 6 to 8, the handle 56 in the form of a fixedly connected to the threaded rod 55 gear 53 is formed in the head 4 and not in the foot 3. It is arranged in this embodiment, the fixed bearing in the head and the mother , which cooperates with the threaded rod in the manner of a spindle drive, in the foot of the device. In this variant too, a cruciform support plate 58 is again provided for fastening the actual lining plates. A tool 50 in the form of a shaft with pinion is located in the working position, for guiding a plurality of bushings or bearings 54, in which the lower end of the tool is rotatably inserted, is provided.

As can be seen in the comparison of the figures, the embodiments according to FIGS. 2 and 8 are particularly simple and robust.

The invention is not limited to the illustrated embodiments but can be modified variously. So it is possible to use friction wheels instead of the gears to the cost of the teeth, which of course does not have to be exact and therefore is inexpensive to produce, continue to lower. In the embodiment of FIG. 2, the individual radial spokes may be interconnected at their free ends with a circular or polygonal ring, whereby the availability of the handle 16 is further improved because the angular position plays no role.

The illustration is deliberately purely schematic to explain the principle of operation of the invention. The technical design of bushings bearings, levers, cranks, the handles on the cranks, etc., is easy for the expert in the knowledge of the invention to select according to his needs and requires no separate representation. The same applies to the design of the bottom side of the foot 3 and the top of the head 4, here are the prior art, various solutions and embodiments to ensure the stability or the strength of the support of the lining plate 1 on the head 4 safely put. This is no longer part of the invention. 4.11
