TOOLED JOINT SEALING STRIP INCLUDING A LATERAL SHEET FOR DEFINING A BOUNDARY FOR THE PAINTING OF EDGES AND PRODUCTION METHOD THEREOF

Abstract

 The invention relates to a sealing strip used in the spray-painting of two adjacent surfaces separated by a tooled joint. The invention is formed by an elastomer body (1) that is used to fill the joint. The upper end of said body is wider than the joint and is in contact with the inner face of the door (3) in order to define a painting boundary along the inner rim of the edge of the door (7), thereby enabling the outer rim (6) and the edge of the door to be painted. The aforementioned elastomer sealing body (1) includes a lateral adhesive sheet (2) which projects out from the surface in order to define a painting boundary along the outer rim (5) of the frame (4) to which the sheet is affixed by means of an adhesive in order to secure the assembly. The invention also relates to a method for producing said sealing strip.

Description

Invention title

[0001] Tooled joint sealing strip including a lateral sheet for defining a boundary for the painting of edges and production method thereof.

Technical field

[0002] The proposed invention is appropriated to the industrial accesories for painting and preparing surfaces of every type of industrial devices, vehicles, furniture or buildings industry.

Background to the previous technical situation

[0003] In the industry of spray-painting, treatment or reparation of surfaces as automobiles bodyworks, boats, vehicles, industrial devices, furniture or buildings, it is necessary to use butt strap strips to avoid paint or another treatment material from penetrate into the joint, but in the state of the art or butt strap strips cause that faults in painting in the rims of the adjacent surfaces that forms the joint appear or else they prevent the edge of the door from being painted or treated.

[0004] Sometimes every type of doors joints are covered by bands or adhesive strips that prevent the painting from penetrating into the joint, but this requires an special treatment of the surface covered by the adhesive band after removing it to allow the uniform finish of the painting or the treatment to be completed and finished until the rim, which entails an additional cost of manpower and a defective finish.

[0005] The patente WO02057024, PCT ES02/00022 (CORTAVITARTE) solves the problem with a wedge or tooled joint of flexible semirigid rubber in a polyhedrical form that inserts by pressure from the outer part of the joint with the closed door and it is of a high cost because of the nature of the rubber material that is used, so it is appropriated to be used or in high-quality and high-cost treatments, or else in that cases when the joint is formed by two parallel planes very thick and long that demand the external introduction of the joint by pressure but not through a plane perpendicular to a frame like a door, since in this last case the new patent allows to solve the joint sealing and the definition of a boundary for the painting not in the outer rim but in the inner one of the door edge making it possible the painting of the edge. In effect, the polyhedrical rubber wedge inserted by pressure covers the surface of the edge of the door and causes an intersection between the tooled joint and the outer, not the inner, rim of the door edge, so when defining a boundary for the painting in this outer rim it prevents the door edge is painted.

[0006] So that the new proposed invention distinguishes substantially of the patent WO02057024, PCT ES02/00022 (CORTAVITARTE) because the new patent when is applied to joints formed by doors on a frame or in general by planes perpendicular to a frame, allows the painting of the whole door edge until the inner rim, makes it possible to define a boundary for the painting of the frame to the outer rim, and since it is not inserted by external pressure on the joint with the closed door but adhered to the frame with the open door it doesn't need to be made of a material with the same characteristics of strengh, endurance and flexibility that rubber has, so it can be made of elastromeric materials like foam rubber or similar which as well as a lesser economical cost they have the advantage that they could be cut by the operator's hand in a short time with no need to use instruments, obtaining a positioning of the joint more quick and effective. The patent US 5939173 (VOSS) consists of an adhesive elastomeric filler body that is introduced into the joint and it adheres to the frame to prevent the painting from penetrating into the joint but it does not allow the definition of a boundary for the painting in the rims of the door nor the frame.

[0007] The patent WO 9521700 (HILLS) consists of an amorphous elastomeric filler body that is introduced into the joint and it is supported by means of a elongated portion to the inner side of the door, but it does not define a boundary nor trace the outline of the painting in the outer rim of the frame (because since it is amorphous it doesn't cause an intersection in a right angle with the rim), nor in the outer rim of the door edge (for the same reason) and it does not allow the painting of the edge of the door until its inner rim. In the proposed invention the band or sheet that projects out from the surface is used to its supporting by adhesion to the frame and since it projects out of the surface it causes the effect of defining a boundary or tracing the outline of the painting in the outer rim of the edge and at the same time by means of the sealing elastomeric body, since the joint is sealed by the contact with the inner side of the door, it allows the painting of the edge of the door until the inner rim.

Disclosure of the invention

[0008] The present invention consists of a tooled joint sealing strip formed by two adjacent surfaces like the one that is formed by the door and a frame like the one that an automobile bodyworks or similar has that is composed by an elastomeric body to fill the joint that has a lateral sheet with an adhesive along its outer side and that projects out of the surface to allow a boundary for the spray-painting is defined in the rim.

[0009] The invention now proposed is appropriated specifically to a joint formed by two adjacent surfaces like the one that is formed by the plane of a door and its frame and consists of a joint that is not inserted by pressure from the outside with the closed door but it adheres to the frame with the open door and when the door closes causes the closing of the joint to be painted making it possible too the definition of a boundary for the painting in the inner rim of the door and in the outer rim of the frame. It consists of an elastomeric body as foam rubber or any other filler material that has a flat lateral sheet or band with an adhesive in its external face to be fixed on the frame. When the door is closed on the frame with the joint adhered to the frame, the elastomeric body closes the bottom of the joint by means of its external or upper face that is in contact with the inner face of the door and that it allows to define a boundary for the painting of the door until the inner rim of the edge. At the same time the lateral sheet or band adhered to the frame is made of a semirigid material and it projects out in respect of the perpendicular plane of the upper or external face of the elastomeric body the necessary height to get round the thickness of the door and to be more than some milimetres from the plane that forms the outer surface to be treated, so that the outer rim of the frame is cut allowing the definition of a boundary or the tracing of an outline of the painting until the outer rim of the frame while the painting is being done.

[0010] It is essential in the new invention that the sealing elastomeric body seals or close up the tooled joint to the height of the plane that forms the inner face of the door to allow the spray-painting or impregnation of the door edge but not the whole joint and that said elastomeric body is joined to a lateral sheet narrower than the tooled joint, this sheet is made of another material with more strenght that projects out the outer plane formed by the two adjacent surfaces to allow to define a boundary or to trace an outline to the painting in the line that is formed by the outer rim of the frame and having the lateral sheet in its outer face an adhesive to the whole set is fixed to the frame allowing that the external or upper face of the sealing elastomeric body gets into contact with the inner face of the door to close up the joint, being both materials of a low cost and susceptible of being cut by hand with no need of instruments to cut.

Figure 2 corresponds to claim 3, figure 3 to claim 5, figure 4 to claim 6, figure 5 to claim 7 and figure 6 to claim 8.

Instructions as to the best way of bringing the invention into effect

[0012] The joint is formed by two elements. As the best way of bringing the invention into effect firstly it is proposed an elastomeric parallelepiped sealing body (1) narrow enough to seal the joint and to get into contact with the inner face of the door and that has in the one of its lateral faces that is in contact with the frame a lateral band or sheet made of semirigid material (2) narrower than the joint to allow the intake of spray-painting in the joint to the closing and it is in a right angle with the external or outer face fo the sealing elastomeric body. The lateral sheet or band on its outer face has an adhesive substance to allow its fixing to the frame (4) and projects out both in respect of the upper o external face of the sealing elastomeric body (1) forming a right angle with it , as well as in respect of the frame (4), enough to produce a dihedron of intersection in the outer rim of the frame, and by means of the upper or external face of the sealing elastomeric body when it is in contact with the inner face of the door, causes the intersection with the inner rim of the door edge allowing the intake of the painting into the joint to paint the door edge, without penetration any more than the line of intersection of the upper or external face of the sealing elastomeric body so at the same time it allows to define a boundary for the painting of the edge of the door until the inner rim of the edge.
