Relevant technical Invention field

The invention is related to a new type of helical (spiral) floating floor pedestal, which is used in the floorings of ceramic, tile stone, tile type wood boards etc, which require variable heights in low height thresholds in the construction sector, in particular in floating floor systems raised with plastic pedestals.

Known status of the technique

In order to install raised floors with ceramic, tile stone, tile type wood boards, which are mostly used in terraces, gardens, pool area and deck-type areas, as a first step, the floating floor pedestals, which are rested on the supporting surface, are placed at appropriate intervals and then the elements forming the floor are laid on the said floating floor pedestals. Currently, there are two types of floating floor pedestals made of plastic with fixed height and variable height (adjustable). Variable height (adjustable) type floating floor pedestals generally consist of a bottom base and a top base in cylindrical form, which have internally threaded structure to lock one another and they are functional between certain heights. A number of tubular bases with riser function are added between the floor pedestal bases in areas with high elevations

While variable height (adjustable) type floating floor pedestals in the conventional technique generally have around 6 mm pitch, wall thicknesses of the pressing plates at top and bottom bases prevent the maximization of the elevation difference by creating a constant value at elevations in closed and open conditions. To overcome this problem, the lower plate of the bottom base is produced as open. In the top base, the base upper plate diameter is formed in such a way that it is equal to the diameter of the screw. In this case, the length of the top base is extended by the top base wall thickness and the length of the bottom base is extended by the bottom base wall thickness so that they are interlocked with each other in a zero state and as a result loss elevations are eliminated. However, even in the fully open position of the adjustable pedestal, a different kind of loss elevation is generated due to the necessity of centring the bottom base and the top base each other (minimum 1 or 2 pitch lengths). If the heights of the pedestal bases are shortened, the elevation loss of pitch height becomes very important. In the 8-25 mm elevations, which can be expressed as low elevations, one pitch causes 6 mm elevation loss and two pitches causes 12 mm elevation loss, therefore the production of the gear type floor pedestal is inefficient and since the difference of the closed and open positions is very small, usually the fixed height pedestals are used. However, when evaluated the elevations between 8-25 mm, even the fixed number of pedestal with a different elevation of 1 mm is increased to 18 and the amount of pedestal and types increases when calculating the project requirements and increases the error probability in product selection in addition, the use of various pedestals in every 1mm elevation difference creates additional workload.

In order to overcome the above mentioned problems, elevated top and bottom bases with helical (spiral) type millimetre stepped teeth are introduced. The helical and gear structures of the bases are compatible with each other thus they can be interlaced and they can be elevated gradually in millimetre size due to position differences caused by rotation on each other. In this type of similar floor pedestals the working ranges of the lowest elevated products are 10-15 mm and 12-18 mm and the measures taken in such products in order to centre the bases, not to slide on each other while fully open and to lock them cannot prevent the loss elevations.

As an example of the known status of the technique, the patent document numbered US20020270978 may be given. Said document relates to a pedestal for raised floors with adjustable height and it includes a gear, cylindrical base member on the inner surface with a gear intermediate element at the top and bottom for resting on the paving surface or an extension and concave-shaped upper member. The upper part is a swinging cover with diaphragm on which the flat elements of the raised base are located.

As another example of the known status of the technique, the patent document numbered W02016IB54228 may be given. Said document is an adjustable pedestal for raised floors, comprising a suitable base for resting on the floor and a head delimited to the base on the elements forming the floor. The said base and the head comprise opposed inclined surfaces, and the rotation of the said base according to the head slides relative to each other against the inclined surfaces, thereby lowering/lifting of the head according to the base is provided. In the present invention, the problem of loss elevation cannot be reduced to zero level.

As a result, the existence of the above problems and the insufficiency of the existing solutions necessitated an improvement in the technical field regarding the installation of the floorings such as ceramic, tile stone, tile type wood boards etc. in the construction sector, in particular in floating floor systems raised with plastic pedestals.

The objectives of the invention

The main objective of the invention based on the conventional technique is to provide a new flooring pedestal eliminating the disadvantages of the conventional technique.

Another main objective of the invention is that the floating floor pedestal is consisted of a bottom base with helical-type elevation gears on the inner surface and a top base coupled to the bottom base by a connecting part with helical-type elevation gears on the inner surface.

Another main objective of the invention is that the operating range is 10-20 mm when the closed condition of the floating floor pedestal is 10 mm, the operating range is 12-24 mm when the closed condition of the floating floor pedestal is 12 mm and the operating range is 15-30 mm when the closed condition of the floating floor pedestal is 15 mm.

Another main objective of the invention is to achieve maximum elevation difference by pulling down the elevation losses consisting of bottom base bottom plate, top base top plate wall thicknesses, centring and sustaining loss/pitch loss to zero level. Another main objective of the invention is to provide a sum of the top base height and the bottom base height without elevation loss at maximum.

Another main objective of the invention is to achieve to equal base heights in line with the highest efficiency and to ensure the elevation of the top base in the closed position to be at 2 times of the elevation of the top base in the open position.

Another main objective of the invention is is to provide a wider range at low- elevated flooring with a single type of floating floor pedestal and to enable fast and economical installation.

Detailed description of the invention The invention is related to a new type of spiral floating floor pedestal (A), which is used in the floorings of ceramic, tile stone, tile type wood boards etc, which require variable heights in low height thresholds in the construction sector, in particular in floating floor systems raised with plastic pedestals and as a general structure, it consists of the following items;

- the top helical elevation gear (1.1), which is positioned at the centre of the bottom base (2) and having progressive pressing surfaces rising helically in the entire circumference of the upper surface, the top base (1) equipped with the top cylinder tube (1.2) in the centre, the top evacuated zone (1.3) between the top helical elevation gears (1.1), the top crank (1.4) at the edges and the top accessory positioning slots (1.5),

- the bottom helical elevation gear (2.1) having progressive pressing surfaces rising helically in the entire circumference of the upper surface, the bottom base (2) equipped with the bottom cylinder tube (2.2) in the centre, the bottom evacuated zone (2.3) between the bottom helical elevation gears (2.1), the bottom crank (2.4) at the edges,

- the ring-shaped connecting part (3) located in the space between the top cylinder tube (1.2) and the bottom cylinder tube (2.2) and equipped with the helical inner channel (3.1) mutually on the inner surface and helical outer channel (3.2) on the outer surface

.

The top base (1) equipped with top helical elevation gears (1.1), having progressive pressing surfaces rising helically in the entire circumference of the upper surface. The said top helical elevation gears (1.1) are formed in multiple single groups on the top base (1) and the area of the pressing surfaces on the top helical elevation gears (1.1) can be narrowed or expanded depending on the progressive structure formed in direct proportion to the force applied by the load to be exerted on the floating floor pedestal (A). The top cylinder tube (1.2) is located in the centre of the top base (1). The said top cylinder tube (1.2) is at the maximum height of the top helical elevation gear (1.1) and the top outer pins (1.2.1) are located at the upper boundary so as to be located externally and reciprocally. The top evacuated zones (1.3) formed between the top helical elevation gears (1.1) are generated such that the peaks of the bottom helical elevation gears (2.1) of the bottom base (2) are nested in these top evacuated areas (1.3) so that there are no vertical gaps. In addition, the top crank (1.4) and the top accessory positioning slots (1.5) are provided at the edges of the top base (1).

The bottom base (2) equipped with bottom helical elevation gears (2.1), having progressive pressing surfaces rising helically in the entire circumference of the upper surface. Said bottom helical elevation gears (2.1) are formed in multiple single groups on the top base (1) and the area of the pressing surfaces on the bottom helical elevation gears (2.1) can be narrowed or expanded depending on the progressive structure formed in direct proportion to the force applied by the load to be exerted on the floating floor pedestal (A). There is a bottom cylinder tube (2.2) of which diameter is greater than the top cylinder tube (1.2) in the centre of the bottom base (2). The said bottom cylinder tube (2.2) is at the maximum height of the bottom helical elevation gear (2.1) and the bottom outer pins (2.2.1) are located at the upper boundary so as to be located internally and reciprocally. The top evacuated zones (2.3) formed between the bottom helical elevation gears (2.1) are generated such that the peaks of the top helical elevation gears (1.1) of the top base (1) are nested in these top evacuated areas (2.3) so that there are no vertical gaps. In addition, the bottom crank (2.4) is provided at the edges of the bottom base (2).

The connecting part (3) is in the form of a ring and equipped with the helical inner channel (3.1) mutually on the inner surface and helical outer channel (3.2) on the outer surface. The inner channel terminator nail (3.1.1) is formed in the upper position of the helical inner channel (3.1) and the outer channel terminator nail (3.2.2) is formed in the lower position of the helical outer channel (3.2). The height of the said connecting part (3) is equal to the remaining size when the wall thickness (t) of the plate to which the top cylinder tube (1.2) is connected is removed from the top base height (x).

The top base height (x) and the bottom base height (y) are equal to each other and the minimum elevation is provided when the top base (1) is placed on the bottom base (2) in the closed position. When in the open position, the sum (z) of the heights of the bottom base and the top base gives the maximum elevation.

The elevation angles of top helical elevation gears (1.1) and the bottom helical elevation gears (2.1) of the top base (1) and the bottom base (2) seated one another can be increased or decreased at the same rate. This situation provides a measurement change in the minimum elevation and maximum elevation but does not affect the operation way.

The mounting and operating principle of the floating floor pedestal (A) is as follows;

The top base (1) is fitted so that the top helical elevation gears (1.1) are facing downwards and centred on the bottom base (2) to provide the minimum elevation. The bottom helical elevation gears (2.1) of the bottom base (2) are facing upwards. While the top base (1) is centred on the bottom base (2), the bottom helical elevation gears (2.1) of the bottom base (2) are nested in the top evacuated areas (1.3) formed between the top helical elevation gears (1.1); the top helical elevation gears (1.1) of the top base (1) are nested in the top evacuated areas (2.3) formed between the bottom helical raising gears (2.1).

The connecting part (3) is positioned out of the top cylinder tube (1.2) in the centre of the top base (1) and so that, the inner channel terminator nails (3.1.1) are facing upwards. Meanwhile, the helical inner channel (3.1), which is located in the continuation of the inner channel terminator nails (3.1.1) sits on the top outer pins (1.2.1) on the outer surface of the top cylinder tube (1.2) and the helical outer channel (3.2), which is located in the continuation of the outer channel terminator nails (3.2.1) sits on the bottom outer pins (2.2.1) on the inner surface of the bottom cylinder tube (2.2).

When the top cranks (1.4) of the top base (1) are moved clockwise and the bottom cranks (2.4) of the bottom base (2) are moved in the opposite direction, the rotation is carried out until the maximum elevation is reached from the sum (z) of the heights of the top base and the bottom base by sliding the top helical elevation gears (1.1) of the top base (1) on the bottom helical elevation gears (2.1) of the bottom base (2). During this movement, the connecting part (3) moves in the vertical direction by rotating through the helical inner channel (3.1) and the helical outer channel (3.2) as long as rotation is in progress. When the maximum elevation of the floating floor pedestal (A) provided from the sum (z) of heights of the bottom base and the top base is reached, the top outer pins (1.2.1) on the outer surface of the top cylinder tube (1.2) are rested on the inner channel terminator nails (3.1.1) at the upper position of the helical inner channel (3.1); the bottom outer pins (2.2.1) on the inner surface of the bottom cylinder tube (2.2) are rested on the outer channel terminator nails (3.2.2) at the lower position of the helical outer channel (3.2). This restricts the rotation in the same direction with the connecting part and prevents the centring of the top base (1) and the bottom base (2) from becoming distorted.
