Description

The The present invention relates to a seat kickstand having the features of the main claim. Furthermore, the invention relates to a method of making a Sitztrittbockes and its use.

The seat trestle can be used as a seat, as a climbing aid and scaffolding trestle. A single block portable chair made of materials such as a urethane foam or a foamed styrene plastic is known from a Japanese patent JP 2001 252 152 A known. This chair has a seat that is used in agricultural work. The block of this portable chair has close to the seat in its outer periphery a slot that serves for attaching shoulder straps.

such Seating must for commercial use of a variety of security relevant Standards such as the accident prevention regulations correspond. Particular attention is paid to its viability and to lay stability. When a portable chair exists in particular the risk of improper use as a climbing aid for cleaning, renovation and construction work. In addition, from safety-related establish a use of such seating as a carrying device for scaffolds questionable. Such carrying devices must a range of DIN and Euronormen as well as occupational health and safety Comply with regulations.

It is therefore an object of the present invention, a Sitztrittbock to be used, which can be used both as a seat, climbing aid and scaffolding frame is and a cost effective Production for a series product allows.

These Task is according to the invention with technical simple means solved by the features of claim 1.

From of special importance for the present invention is that at least one side of the block with a texture is provided. By means of the texture can a surface texture be created on the side of the block, which in particular and is non-slip. This page can of course also as seat be used, since the block of foamed polymer also a pleasant sitting experience is produced. Furthermore, by means of texturing a secure Storage and resilient support surface provided for floors of a scaffold become.

From A particular advantage here is that the corners and edges of the block are dull to the risk of breaking out of block parts too minimize or stumble upon entering the block or jamming of fingers when placing scaffold floors on the block to prevent. Dull corners and edges can rounded, beveled and / or graded.

A particularly efficient embodiment of the Sitztrittbockes is achievable, if the block in the form of a Cuboid is formed. The sides of the cuboid are approximately rectangular arranged to each other, each with a pair of opposing Pages are approximately parallel to each other. This can after Aligning the seat kickstand on the ground on the opposite textured side a pewter scaffolding structure will be constructed. A block with three different edge lengths along the major axes can by mere Pivoting different heights reach the textured side of the ground. The block-shaped block can also have a square side surface, wherein the block for example, about the same height as width to an increased Tilting safety with uneven load to ensure. To increase the stability, the block can be formed in particular in the form of a cube be.

These Form of the block also has the advantage that the load to be removed mostly in terms of area on the Substrate transferable is. In less sustainable Underground, such as a not yet completely hardened concrete or a damp and uneven ground in the outdoor area, the load can be better be distributed. Unlike a commercial ladder or scaffolding frame can the seat trestle is not only selectively supported on the ground.

To achieve a weight reduction of the Sitztrittbockes, the block is made of a foamed polymer. The polymer contains, for example, a thermoplastic foam such as expanded polystyrene, polypropylene or polyvinyl chloride - short PVC-, which above a material-specific Glass temperature is processable. This can also be done later texturing or structuring of the page. In particular, a proportion of polystyrene ensures a certain amount of heat and does not become slippery when wetted with water. As an elastomeric foam, for example, polyurethane flexible foam and Nitrilbutadienkautschuk - short NBR- into consideration. A share of NBR ensures in particular special for increased static friction of a textured wing. A thermosetting foam contains, for example, a rigid polyurethane foam or a phenoplast. The latter provide a low bulk density for a high compression hardness, so that a multiple of the own weight of the Sitztrittbockes can be supported with high dimensional stability of the block.

It is for the skilled person that the different polymer foams also Can be used in combination to appropriate properties of the block. Without limiting the invention to want, could the block a core of thermoplastic foam with a sheath a thermosetting foam. Such foams are mostly stable against different media such as water, solvents and the like, so that a damage through dripping materials such as mortar, paint, cleaning agents or sealants do not cause damage that could endanger the safety.

Around with high structural strength of the block an easy to transport To provide Sitztrittbock sees an advantageous development the invention in that the foamed polymer has a bulk density from about 15 kg m-3 to about 30 kg m-3. In particular, can the block large volume be designed, which is worn or moved by a person can be. Thus, a quick positioning of the seat stalk is possible.

To an advantageous development of Sitzgestellbockes is with set the texture side from the longest edge of the block. As a result, in particular, the side of the block provided with a texture be that a maximum surface area having. This can on the one hand provide an increased bearing surface for scaffolding floors, on the other hand the accident prevention regulations enough tread define. This bearing surface can continue as elevated storage space for tools, Building materials, cleaning agents and the like are used. An increased storage such aids, for example, protects the joints in the Homework, as a permanent bend, Squatting or kneeling is avoided.

at a block in the form of a polyhedron could in particular be identical Size and shape the pages inadvertently leave a non-textured page as a seat, Performance or wing be used. A further advantageous embodiment of the Sitztrittbockes provides that at least one with the texture provided side is colored with a signal color. Just under bad Light and visibility conditions is the performance area easily recognizable, which in particular increases slip resistance. A filmy Coating the textured side could also wear it out and / or damage Show. This coating of signal color can be approximately 1 μm thick the texture will be applied. A particularly comfortable side of the Blocks can also be colored differently its as a textured side, prepared as a tread is.

to Improving the seating position or the seating comfort can be the texture include a recess that is adapted to a buttocks or during prolonged sitting on the Sitztrittbock avoids heat build-up. The depression can also be designed so that moisture absorbed by the depression being, being a big part the textured side remains dry. This lowers the risk of one Slipping or slipping on the seat stool. The deepening of Texture can furthermore be designed as a receptacle for scaffolding floors of a work scaffold, which makes slipping, moving or tilting of the scaffolding floors effective can be prevented. The texture may have an elevation. The survey may for example be formed by ribs, the provide an extremely slip-resistant tread. By a Combination of pits and elevations on a textured Page can realize a safety-related particularly high-quality multi-purpose area become.

By Point, line, pimple, waffle and / or wave-like structures can individual sections of a page to special occupational health and safety Regulations are adjusted.

A for the Series production sees particularly cost-effective embodiment of the invention that the structures are arranged symmetrically to each other. By means of a heat deformation process could be a rapport of the structures be created on one side of the block. Also is an asymmetric Arrangement of the structures of the texture possible to be independent of an orientation of the Sitztrittbockes a sure-footed, slip-resistant or to provide a comfortable fit side.

to improved handling of the Sitztrittbockes it is envisaged that the block has a handle for carrying and rotating the block. Due to the low weight of Sitzgestellbockes can Orientation changed slightly become.

A Particularly advantageous development of the seat trestle according to the invention is designed so that the handle of a recessed grip close to Edge of the block is defined, with a running approximately parallel to the edge Section of the recessed grip is undercut. A large volume Block can thereby be transported with one hand or to be pivoted about one of its main axes.

To a further embodiment the invention, the seat staging block is further formed so that a block by means of the texture to another block of a Sitztrittbockes attachable is. For example, the texture has an area whose elevation corresponds to the pits of one area of the texture of the other block. This is of particular importance for stacking Sitztrittböcken invention to a prevent accidental slippage of a block in a stack. Of course can the recesses of the texture for connecting the seat staging blocks with each other be designed for receiving reinforcements and stiffeners.

The The present invention further relates to a method of manufacturing a Sitztrittbockes with a block of foamed polymer, at least one as a support and tread formed side is provided with a texture. The procedure can be designed so that a block of foamed polymer will be produced. In a further step, the texturing carried out on at least one page. Could also the block is made in a mold by foaming the polymer be at least one side of the block of a mold section is provided with the texture. For this purpose, the mold section has a negative the texture on. Further expedient method steps result from the above description of embodiments of Sitzgestellbockes.

1 shows a seat kickstand 10 with a block 12 made of foamed polymer, which one as Supporting and stepping surface 16 trained side 14 having. To enter the Sitztrittbockes 10 a particularly slip-resistant surface 16 to provide, is the page provided for this purpose 14 with a texture 18 Mistake. The block 12 consists of an extruder foam 20 which comprises substantially foamed polystyrene. The block 12 is cuboid shaped and has three substantially equal edge lengths. The one with the texture 18 provided page 14 has an approximately square tread surface 16 on. The cube-shaped block 12 This is so high that a normal sitting position for an adult of about 45 cm is reached. Thus, it is possible in execution of craft activities near the ground comfortably on the Sitztrittbock invention 10 to sit. When performing work close to the ceiling, the seat kickstand becomes 10 used as a climbing aid. It is of particular advantage that the textured side 14 a variety of wells 22 has, which improve the slip resistance significantly. This is the surface texture of the tread surface 16 formed by polymer components such as nitrile-butadiene rubber, which is used as sole material, particularly slip-resistant.

To straight with a cube-shaped Sitzbetbock 10 the performance area 16 easily recognizable, is the one with the texture 18 provided page 14 marked with a signal color.

To avoid damage to the block 12 are the corners 13 and edges 15 rounded. To facilitate transportation or change of position during use, the seat kickstand 10 a handle 28 on. The handle 28 is from a recess near the edge 15 of the block 12 provided so that a thumb from a user's hand on the textured side 14 into a depression 22 engages while the remaining fingers of the hand into the recess of the handle 28 are supported. Thus, it is also easily possible Sitzbock 10 to turn. This is especially true for others with the texture 18 provided pages 14 advantageous.

The foamed polystyrene is foamed by means of an inert propellant gas such as carbon dioxide or nitrogen, whereby a bulk density of about 15 kg per cubic meter is set. Such materials are used for insulation of the facade and are despite a low density sufficient dimensionally stable under pressure load. At one volume of the block 12 of up to 1 cubic meter is the seat kickstand 10 Furthermore, to move or wear by a person without further aids on a construction site. Furthermore, the material is soft enough to ensure a durable and comfortable sitting on the seat kickstand 10 to ensure. Up to a pressure load of about 80 kg per square meter, the material used is dimensionally stable so that from a safety point of view, use as a climbing aid is harmless.

The cuboid configuration of the Sitztrittbockes 10 offers in comparison to a ladder and the like the advantage that a surface-like contact with an uneven surface, as it is found for example in the exterior of a shell, occurs almost inevitably. This increases the stability of a seat kickstand used as a climbing aid 10 considerably.

In 2 is a second embodiment of a Sitzgestellbockes invention 10 shown in a schematic sectional view. An in 2 shown below first seatstep 10 includes a cuboid block 12 of foamed polymer, which is in the form of a thermoplastic foam 20 is trained. The block 12 points to one of its longest edge 15 limited page 14 a texture 18 on, with a series of symmetrically spaced elevations 24 is provided. In this cross-sectional view through the block 12 It can be seen that the between the tread surface 16 and the page 14 extending side walls are issued. These side walls have a slope of about 40 ° to about 60 ° to the side 14 on. This increases on the one hand the dimensional stability of the surveys 24 and on the other hand ensures good protection against damage to the same. By means of a uniform almost equidistant arrangement of the surveys 24 on the website 14 of in 2 seatbelt shown below 10 gets from the texture 18 a first area 34 provided, its contour 36 into the contour 36 the texture 18 a stacked second Sitztrittbockes 10 is attachable.

The in 2 Seat trestle shown above 10 has substantially the same dimensions as the lower Sitztrittbock 10 , The upper seat pedestal 10 is only rotated by 90 °. Consequently, in the sectional view of both stacked seat blocks 10 you can see that the texture 18 over the entire surface of the page 14 of the block 12 extends. The entire width of the block 12 hereby sets a second area 35 ready, its contour 36 with the contour 36 of the seat pedestal shown below 10 corresponds.

To increase the compressive and structural strength, the foamed polymer in the form of a foam 20 a gross density of about 20 kg per cubic meter. The dimensions of the block 12 are chosen such that the edges 15 have three different lengths. The length of the block shown below 12 is about 20 cm longer than its width according to the Sitzgestellbockes shown above 10 , As a result, part of the texture remains 18 provided side 14 of the lower seat kickstand 10 as a performance area 16 freely accessible. Thus, it is possible, a combination of two stacked Sitzgestellböcke 10 how to use a two- or four- to five-pronged ladder with a total height of up to about 1m.

Furthermore, in 2 a handle 28 shown, whose recessed grip 30 at the upper seat kickstand 10 in frontal view and at the lower seat kickstand 10 can be seen in the lateral cross-section. To embrace the block 12 To make it particularly safe, one is close to the transverse side of the block 12 extending side wall of the recessed grip 30 with an undercut 32 Mistake.

3 shows a construction of three substantially cuboid Sitzgestellböcken invention 10 , which can be used as a staircase. The three seatstays 10 consist of a block 12 with a foamed elastomeric foam 20 made of polyvinyl chloride. The three blocks 12 Show at least two with a texture 18 provided pages 14 on, with the Sitztrittböcke 10 are joined together in such a way that each one as a step surface 16 serving side 14 remains freely accessible. As in 3 can be seen, is to protect against breaking out the corner 13 beveled. One to the performance area 16 approximately at right angles extending side 14 is also with a texture 18 provided in the texture 18 of in 3 shown middle Sitztrittbockes 10 is attachable. This in the use position of the Sitztrittbockes 10 in approximately vertical texture 18 is here designed so that the opposite recesses 22 in a corresponding survey 24 of the middle seat stump 10 take up. Combination of the two side-by-side seating stands 10 is thanks to the texture 18 achieved a certain adhesion and clamping effect.

In the 3 illustrated Sitztrittköcke 10 each consist of one block 12 which is made of a foamed polymer. The blocks 12 contain a thermosetting foam 20 which is essentially formed of expanded polyurethane with a bulk density of about 30 kg per cubic meter. With increasing density, the pressure and load-bearing capacity of the Sitztrittböcke invention increases 10 such that the in 3 shown construction can be used as makeshift stairs. The texture freely accessible on the upper side 18 has a knob-like structure 26 which shows excellent slip resistance and skid resistance even when wetted with moisture.

To further improve slip resistance is the freely accessible remaining part of the texture 18 provided with a signal color, in particular a fluorescent or phosphorescent coating. Appropriate Pigmen te the signal color can on the side 14 be applied or admixed to the polymer during the extrusion process.

By texturing multiple pages 14 a block 12 It is thus possible to have a first area 34 the texture 18 for a juxtaposition of another seat block according to the invention 10 to enable. It is particularly noteworthy that such a region additionally wave-like structures 26 has, which are arranged asymmetrically to each other. When attached together to a second area 35 a textured page 14 of in 3 Centrally represented Sitztrittbockes 10 can by simply compressing the adjacent Sitztrittböcke 10 a positive connection can be made.

At the in 4 shown construction of three Sitztrittböcken invention 10 is an easy-to-use Tritterhöhung realized. The in 4 Seat pedestal shown above 10 has four pages 14 on that with a texture 18 are provided. The structure 26 the texture 18 is here wave-shaped, so that a first area 34 over the entire width of the seat stalk shown in cross-section 10 with the texture 18 of the underlying staging block 10 is to be engaged. The structural elements are in this case arranged symmetrically to one another, so that the Sitzgestellbock shown above 10 another first area 34 that has a second area 35 of the seatbelt illustrated on the right 10 is connectable. In other words, the texture runs 18 of the lower seat kickstand 10 completely around its block 12 so that around the block 12 several other Sitztrittböcke invention 10 by means of their textures 18 are attachable.

By stacking up of Sitztrittböcken invention 10 can the tread surface 16 be increased so that when working indoors with standard height of the user room heights of 2.50 m to about 2.90 m are easily editable. The two provided performance areas 16 the in 4 In addition, the combination shown makes it possible to provide different seat heights. So can at For example, during restoration work on a facade, the lower tread surface 16 when cleaning a building base and the second increased surface area 16 For example, be used when working in the eaves area. The increased surface area 16 can also be used as a storage facility for tools and ready-to-use building materials.

Another example of application of a Sitztrittbockes invention 10 is in 5 shown. Here are two Sitztrittböcke 10 used as height-adjustable scaffolding feet, one with texture 18 provided wing 16 of the blocks 12 almost as a console for a scaffold floor, especially from planks 38 , are used. The blocks 12 consist essentially of a foamed polymer containing a thermoplastic foam 20 a derivative of the polypropylene in expanded form. Such materials, in addition to high moisture and media resistance on a considerable dimensional stability under compressive stress. The texture 18 includes groove-like structures 26 , in particular for supporting the screed 38 are formed. An unintentional slipping of the planks 38 is effectively prevented. For safety reasons, at a height of the planks 38 from more than 1m by means of fittings an additional scaffold pole on the seat step block 10 fixable. The scaffolding pole serves as a handrail, which provides a fall arrester. As in particular from the in 5 Ausführungsbei shown on the left of a Sitztrittbockes 10 can be seen, just by turning the block 12 different levels can be set for the skeleton arrangement shown schematically. In masonry work is with progressive wall height by means of "upright" places of the block 12 adjust the framework height to the wall height. Thus, the Sitzbetbock invention is 10 in comparison to a conventional stool, a kick or a ladder in addition to a use as a chair, climbing aid can also be used as a scaffolding foot. The surface texture of the page 14 is designed for this purpose that part of the texture 18 a comfortable seat, another part of the texture 18 a non-slip surface 16 , as well as another part of the texture 18 an abutment for planks 38 a scaffolding provides.

Another construction of Sitztrittböcken invention 10 is in 6 shown. The essentially cuboid blocks 12 have about three different edge lengths. The opposite sides 14 a block 12 either have no texture 18 , a page 14 with texture 18 and an opposite congruent side 14 without texture 18 or are two-sided with a texture 18 Mistake. The textures 18 are essentially symmetrical of in-line wave-like structures 26 formed, which add together from adjacent Sitztrittböcken 10 using subregions of the texture 18 enable. The edge lengths of the individual blocks 12 are coordinated so that when Aufeinaderstapeln several Sitztrittböcke 10 Two scaffold feet, shown here on the left and right respectively, emerge whose topmost wings 16 mutually horizontal brackets for a scaffold floor, such as a screed 38 to provide. In the 6 right illustrated construction of four Sitztrittböcken 10 is so zusammenge that a stair-like staircase on the freely accessible remaining surfaces 16 is provided.

With the in 7 shown method 100 is one of the aforementioned Sitztrittböcke 10 manufacture. The method according to the invention comprises producing a block 12 of foamed polymer and creating a texture 18 on at least one page 14 of the block 12 , This page 14 serves as a supporting and stepping surface 16 of the Sitztrittbockes 10 , The block 12 is prepared by contacting two reactants, such as isocyanates and polyols, to form a polyurethane polymer which is foamed by the addition of water. The added water forms with the isocyanate partially carbon dioxide, which serves as foaming agent for foaming. To set a specific density of the polymer and gas is added. From the solidified polymer foam is then a block 12 with dull corners 13 and edges 15 cut out. The as wings 16 provided pages 14 of the block 12 are finally laminated with a signal-colored sheet of thermoplastic polymer, which has a texture 18 with knob-like structures 26 includes.

Another variant of the method according to the invention 100 is in 8th shown. A polymer is melted and foamed with a propellant gas, as indicated by an arrow, and pressed in the form of a continuous strand which is cut to length as a block 12 of the Sitztrittbockes 10 is being used. At least one page 14 of the endless strand is using a tool 44 processed. The performance area 16 gets a texture here 18 with a variety of wells 22 , This is the tool 44 by the directions of movement marked with arrows 45 in terms of the block 12 postponed. The tool 44 created depressions 22 form a predefined rapport, the secure toothing of several Sitztrittböcke 10 allows.

At the in 9 shown embodiment of a method 100 for making a Sitztrittbockes 10 the texturing of a page takes place 14 of the block 12 along with the generation of the block 12 made of foamed polymer. For this purpose, the molten polymer is foamed with a propellant gas and into a mold 40 filled. Form 40 gives the later shape of the Sitztrittbocks 10 in front. In particular, is a seat kickstand 10 to produce with three different edge lengths. A form section 42 the form 40 is with negatives of the desired texture 18 Mistake. After cooling, curing, etc. of the polymer used becomes the Sitztrittkock 10 out of form 40 taken. At least one page 14 of the block 12 indicates the texture 18 on. This page 14 finally serves as a supporting and stepping surface 16 , Also is a recessed grip 30 in the form section 42 pre-definable.

Analogously, the liquefied polymer is within the mold 40 foam with the propellant gas. The mold section 42 may also have a registered trademark in negative form. The Sitztrittböcke thus produced 10 have as an advertising medium on the performance area 16 the logo of a sponsor.

The The present invention discloses a seat kickstand with a block from foamed Polymer, which due to a low density easily too transport is. Because at least one side of the block with a Texture, the seat kickstand can be used both as a seat, Climbing aid and scaffold base used become. The Sitztrittbock finds especially in handicraft activities Application. The attachable due to the texture Sitzgestellböcke can cost and masses of blocks be cut by extruder foam, wherein when using a thermoplastic polymer by hot deformation different designed textures can be created on the page.
