Definitions

• the known spacer therefore requires an intermediate layer, a suction cup and a counterholder for its functioning, that is to say a very high production outlay for such a mass article
• the object of the present invention is to provide a spacer for arrangement between at least partially aquidistant surfaces of temporarily adjacent components, in particular between disc or tabular components, in such a way that it adheres reliably, takes on the loads that arise and can be reused is
• this spacer consists of only two elements, one of which, the adhesive element, is responsible for the exact adherence to the position determination, but not for the application of the necessary support forces, while the other, the support element, takes over the support forces in a precisely defined manner
• Spacers can be provided with an adhesive element on each of their two end faces, in order to achieve adhesion to each of the components lying on both sides
• the spacer according to the invention can be designed in such a way that the adhesive element and the support element are adapted to the contour of the component to be placed on top. This is particularly useful when stacking curved components
• the spacer according to the invention can be designed such that the cross section of the support element is adapted to the contour of a receptacle of the component to be placed on it.
• the spacer engages in the receptacle and thus reliably ensures the desired placement of the components with respect to one another
• the spacer according to the invention can be designed in such a way that the support element and adhesive element (s) are produced as a one-piece injection-molded part made of plastic. In many cases, this can greatly reduce the cost of producing the spacer
• the adhesive element can be connected in any way to the support element. It is only important that the adhesive element and support element always have a defined association with one another
• the spacer according to the invention can be designed in such a way that the adhesive element is a suction cup that is open to the outside.
• the suction cup can be designed in any conventional manner. For example, to determine the wall thicknesses. It is also possible to use rubber, PVC, silicone or the like as the material for the suction cup and to use a harder material for the support element, for example a polyethylene, polyamide or polyurethane is expedient it to use materials of the same kind for the support element and adhesive element, which do not have to be separated from one another in the case of later recycling
• the adhesive element can be firmly connected to the support element in any known manner
• the suction cup is detachably connected to the support element.
• This version is particularly suitable when using different materials that are not easily connectable in one piece. It also has the advantage that when using significantly different materials for Adhesive element and support element for recycling a separation of these materials can be carried out without further ado. This proposal also has the advantage that an element can be exchanged in the event of damage to an element.
• the spacer according to the invention can also be designed such that the suction cup has a molded-on attachment projection which projects centrally from the side opposite its cup side and engages in a form-fitting manner in a hole in the support element
• the spacer according to the invention can also be designed such that the adhesive element is formed by a flat part made of plastic which is self-adhesive on its outer surface. This embodiment leads to a low overall height and accordingly allows the distances between adjacent components to be kept small
• the advantage of a low overall height also results if the adhesive element is formed by a flat part made of molded plastic, the part being provided on the outside with an adhesive which permits repeated adhesion and detachment on a component
• the spacer according to the invention can also be designed such that the adhesive element consists of a flat part made of foamed plastic, the pores of which are open on one side in the area of the outer surface. This results in micro suction cups. with the advantages of low overall heights and also reliable liability
• the spacer according to the invention has the advantage in all of its designs that it is reusable, that is, it leads to considerable material savings
• embodiments of the spacer according to the invention are described with reference to drawings
• FIG. 1 perspective view of an embodiment of the spacer according to the invention with a suction cup
• FIG. 2 shows two sectional representations of the spacer according to FIG. 1, one in the unloaded state before being placed on a glass pane and one in the loaded state after being inserted between two glass panes, and
• FIG. 3 shows two sectional representations relating to further embodiments of the spacer according to the invention, one in the unloaded state before being placed on a glass pane and one in the loaded state after insertion between two glass panes
• a spacer 1 consists of a cylindrical-disc-shaped support element 2 and a firmly but detachably connected adhesive element in the form of a suction cup 3 with an edge-side sealing lip 4.
• the outer diameter of the suction cup 3 is smaller than that of the support element 2.
• the outer contour of the spacer is irrelevant It can be round or polygonal
• the construction of the spacer 1 can be seen in particular in the sectional view according to FIG. 2.
• a recess 5 is provided in one of the end faces of the support element 2.
• the clear space is dimensioned such that the suction cup 3 can be completely immersed therein in a partially compressed state the recess 5 is slightly larger than the outer diameter of the sealing lip 4.
• An undercut hole 6 is provided centrally at the bottom of the recess 5, which can be made as a blind hole or, as shown here, as a through hole.
• the suction cup 3 can be separated from the support element 2 with increased effort. The loosening force required for this must be greater than the lifting force with which the complete spacer 1 can be separated from a smooth surface. If the hole 6 is designed as a through hole, the suction cup 3 can be used Use a suitable pin-shaped tool to push out the back of the recess 5 without destroying it. This detachable connection supports the replacement of a defective suction cup 3 and finally the material separation when the two different materials of the spacer 1 are recycled
• FIG. 2 In the lower part of FIG. 2 it can be seen how the suction cup 3 is completely immersed in the depression 5 between two glass panes 9 after the spacer 1 has been inserted. A small volume of air is still enclosed between its cup side and the lower glass pane 9, while the outer edge of the depression 5 is seated on the lower glass pane 9 and the upper glass pane 9 is supported on the upper side of the holder or the support element 2 with the desired or required distance.
• the suction cup 3 is therefore completely relieved of all support forces and thus safely protected against overload after being put on a glass pane 9, the spacer 1 can also be positioned in the surface without detaching it again.
• the suction cup 3 or its sealing lip 4 can temporarily come into contact with the inside of the recess 5 and is carried by it
• the height of the spacer 1 is determined by the requirements for the distances to be maintained between the glass panes 9. A lower limit for the height results from the height of the suction cup 3 together with the fastening projection 7.
• the thickness of the support element 2 can be reduced to such an extent that the free end face of the fastening lug 7 completely inserted into the hole 6 is just flush with the top of the support element 2, so that the effective height of the spacer thus formed is substantially the same as the height of the unloaded suction cup 3
• a support element 2 is provided, which likewise has a depression 5 on its one end face.
• a flat part 11 made of elastically compressible plastic is attached to this depression and fastened to the base of the depression in the relaxed state of the part 1 1 this protrudes over the lower end face of the support element 2
• the part 11 is coated on its outer surface 12 with an adhesive, with which a detachable connection to a contact surface of a workpiece 13 to be protected can be repeatedly made
• a part 14 made of an open-pore plastic is used.
• the pores in its outer surface 15 are open on one side and, when pressed against the contact surface of a workpiece 13, act like small suction cups. When pressed against a contact surface, the adhesive sticks Spacers on this surface In the lower part of Fig. 3 it is made clear that the part is fully pressed into the recess under load, the height of the recess ensuring that there is no squeezing, so that the elastic back parting of the part decreases Relief remains fully intact
• the support element can have cutouts which, on the one hand, reduce the material consumption and, on the other hand, specifically serve to adjust the stiffness or elastic compliance and buffering capacity of the support element. These cutouts can also be formed in the support surface facing away from the suction cup
