Description

An applicator for applying sealants and for smoothing

FIELD OF THE INVENTION

Present invention relates to aids used in the construction industry, which help to finish and compress the sealing material applied to joints and gaps of various surfaces. The invention relates preferably to the applicator used for applying and smoothing the sealing material, which applicator is attached for example to the nozzle of the sealing material tube.

PRIOR ART

Prior art discloses several solutions that employ an applicator with wing sections attached to the end of the tube for a viscous material, designed for smoothing the viscous material and removing the excess material. Wing sections form an edge, which allow smoothing the viscous material on surfaces or in corners. E.g. WO2012150471 describes such device for applying viscous material on the surface.

Document US2006/231964, 19.10.2006 (Woods, John) describes cylindrical tube nozzles that can be used to correct or seal patterned surfaces. A trowel has been added to the cylindrical tube nozzle, which can be used for creating an additional pattern on the surface.

Document US 2012/180718, 19.07.2012 (Martin, Xavier) describes a device or appliance that is used for applying a protective layer on the edges of thin details (e.g. sheets of metal). The device is used for creating a galvanic protection or anti-rust protection for the edges of details, whereas the protective material is applied only on the edges. The appliance comprises a base, sliding along the edge of the detail with cheeks on both sides, each of which resting on the side surface close to the edge of the workpiece. The base of the appliance features a support surface for the protective material tube together with a collar, used for fixing the tube on the base of the appliance, and a passage has been created in the base for the tube nozzle the diameter of which corresponds to the tube nozzle diameter so that the conical nozzle of the tube is fixed in that passage. Also, in the first part of the base of the appliance there are provided small wheels, which support and facilitate the sliding of the appliance along the edge of the workpiece.

US5,346,380, 13.09.1994 (Abies, James) describes the tip of the sealing material tube, which can be used for sealing hard-to-reach joints. Also, a spoon-like spatula, to be attached to the nozzle for smoothing the sealing material in the joint and for removing the excess sealing material has been described. The spoon-like spatula has been attached to the collar, which in turn is attached to the tube nozzle. A safety nut has been provided for fixing the mounting collar of the spatula on the tube nozzle and in an alternative solution an adjustment screw has been added, which changes the distance of the spatula from the sealed surface. The structure is made uncomfortable by the fasteners designed to attach the spatula to the tube and adjustment of the height of the spatula in the used fastener. When sealing the gaps or joints of details the glue or sealing material inevitably gets into the fastening and adjustment means, which then dries up there and makes using these uncomfortable, because the fastening means must first be cleaned from the glue of sealing material and only then can the spatula be removed from the tube nozzle or its height adjusted relative to the sealed surface.

Document DE10201 1076412 A1 , 29.1 1.2012 (Bosch GmbH) describes a spatula attached to the tip of the glue gun, allowing to remove from the joints the excess glue used for joining the details so that it would result in a uniform glue joint. The spatula consists of a flat peeling portion, which is attached to the tip of the glue gun with two rods. The deficiency of this solution lies in the fragility and impracticality of the entire structure because the peeling portion is made of a rigid material.

The deficiency of earlier materials lies largely in the rigidity of the smoothing surface and in removing the excess material from the surface. None of the prior solutions follows the human finger shape and elasticity.

DISCLOSURE OF THE INVENTION

The object of present invention is to provide an applicator used in construction or repair work, which, during applying the sealing material, mastic or other elastic material to the joints or gaps of various surfaces, helps to smoothen or remove or collect said excess material. "Sealing material" is intended to include in the context of present invention silicone (e.g. curing in the air), sealant or other viscous material (e.g. gum, various glues used for sealing joints, etc), which is used for example in the corners of walls or ceilings, gaps between surfaces (joints) as an elastic material that provides corresponding joinings the necessary density, impermeability and appearance.

Also, the object of the invention is to collect the excess viscous material, which has spread from the nozzle of the tube containing the material onto joints of gaps of surfaces.

Also, the object of the invention is the easy attachment of the applicator to the tube of viscous material or the nozzle that is attached to the tube. The object of the invention is also the easy removal from the applicator of the elastic smoothening pad used for smoothening, in order to clean it or replace with a new smoothening pad.

The applicator according to the invention comprises the attachment portion or base, attached to the sealing material tube, which is made up of the conical pipe collar that is attached to the nozzle of the tube of the viscous material and of the support of the smoothening pad. The support represents a channel into which the rotatable or raised portion is attached by an axle. In the raised part a footing moves linearly and the smoothening pad has been attached to it. The support stays in such an angle relative to the base so as to provide the customary angle between the tube of the viscous material and the surface being sealed.

The shape of the smoothening pad has been designed in such a manner that it would imitate the finger that is pressed into the corner, whereas the smoothening pad is a pad made of elastic material (e.g. silicone) that is backward expanding and with wings copying the wall surface. There is an elevation in the centre of pad, allowing to direct the excess viscous material accumulated on the pad back to the sealed or smoothened surface or to the corner between the surfaces. In alternative solutions the shape of the pad has been altered according to the desired smoothening grade or the material used for sealing the corners/surfaces. The applicant makes a reference herein to the Estonian patent application No. P201400037, 25.10.2014, submitted previously by the present applicant, and to the International Patent Application (PCT/EE2015/00003), submitted on the basis of former, which includes the technical description of the solution, which can be used to better understood and define the content, exemplary embodiments and figures of the present patent application. Also, the features described in the aforementioned international application description and claims can be used as a reference in present application.

PREFERRED EMBODIMENT The applicator 10 according to the invention (Fig 1 ) comprises the attachment portion or base 2, attached to the sealing material tube, which is made up of the conical pipe collar 1 1 that is attached to the nozzle of the tube of the viscous material and of the support 12 of the smoothening pad. The support 12 represents a trough-shaped element or channel 13 into which the rotatable or raised portion 3 is attached by an axle. In the raised portion 3 a sled 18 moves linearly with the footing 14 of the smoothening pad to which a smoothening pad 15 has been attached. The support 12 is positioned below the base 2 at such an angle that when the raised part 3 together with the footing 14 of the smoothening pad and the smoothening pad 15 has been rotated forwards to the working position (i.e. to the front of the nozzle of the sealing material tube for resting on the treated surface or the connection corner of details), there would be an angle provided between the tube of the viscous material and tube nozzle and the sealed surface, which would be necessary for the user to have an overview of the amount of sealing material squeezed to the joint and of the smoothening quality of the joint.

The shape of the smoothening pad 15 has been designed such that it would imitate a human finger, whereas the smoothening pad is a pad (Fig 26, 28, 30, 32) made of elastic material (e.g. silicone) that is backward expanding and with wings copying the wall surface. There is an elevation 45 (Fig 30) in the centre of smoothening pad, allowing to direct the excess viscous material accumulated on the pad back to the sealed or smoothened surface or to the corner between the surfaces. The smoothening pad displayed on Fig 31 A to 31 C, 32 is designed for using in general finishing of corners with e.g. acrylic material, silicone, polyurethane-based sealant, putty, bitumen-based paste, etc. Also, all are provided with other smoothening pads of different shapes according to the invention. The face 21 of the smoothening pad 15 imitates a human finger, which has been pressed into the corner (normally the user actually employs his/her finger for smoothening the silicone used for sealing e.g. the corner joints of details, because its surface allows firstly to smoothen the sealing material and secondly to remove the excess sealing material). The smoothening pad lacks a cavity in the front portion, which enables the front part of the smoothening pad 24 to travel as much as possible in the corner. There are upward wings 22 on the sides of smoothening pads, which copy the wall surfaces onto which the wings of the smoothening pad are pressed when finishing the corner with a viscous sealing material. There is an elevation 23 in the centre of the smoothening pad, allowing the excess viscous material accumulated on the front part of the pad to be guided back to the finished corner.

The smoothening pad is designed in the second solution of the applicator so that it allows to finish planar surfaces, e.g. to smoothen the viscous material pressed into the joint between two panels. Fig 27A to 27C, 28 show a smoothening pad for planar finishing. In that occasion the front edge 31 of the smoothening pad is straight and the face 32 is curved. There is a backward narrowing or expanding cavity 33 in the centre of the smoothening pad for guiding the viscous material and collecting the excess material. In the front part of the cavity 33 there is a small nook 34, which allows to create a small elevation on the joint between planar surfaces.

The smoothening pad in the third solution of the applicator has been designed for fine finishing of and applying silicone to corners (Figs 29A to 29C, 30). Similarly to previous embodiments the face 41 of the smoothening pad imitates a human finger, which has been pressed into the corner so that the wings copy the wall surface and remove the excess viscous material from the wall surface and guide it to the cavity 43 in the centre of the smoothening pad. There is a small nook 44 in the connection point of the cavity 43 and face to better guide of the excess material into the cavity 43.

The fastening of the smoothening pad 15 to the footing 14 of the applicator is also essential in the general embodiment of the invention (See Figs 23, 24). A pocket 19 is provided in the lower surface of the smoothening pad 15. The pocket can be designed so that in forming (moulding, pressing, die-casting) of the elastic smoothening pad a more rigid plastic element has been placed on the bottom of the mould, which represents an element with upturned edges and in forming the elastic pad it remains in the material of the smoothening pad, so that a pocket is formed, which has a slit/opening on its bottom. A sled 18, travelling in the channel of the raised part of the applicator, is pushed into the pocket of the smoothening pad, whereas there is a footing 14 at the end of the sled for attaching the smoothening pad. The internal shape of the pocket 19 corresponds to the shape of the footing 14 (head of the footing is generally triangular) and there is an opening 191 on the bottom of the pocket. The pocket is located higher above the lower surface of the pad so that a step 192 is formed behind which protrusions or teeth formed on the end of the footing 14 attach. The end of the footing 14 has been split into two arms 142, both of which have a protrusion or tooth 17 on their sides. A slit 141 on the end of the footing allows pressing together the arms 142 of the footing when the end of the footing reaches the opening 191 on the bottom of the pocket of the pad. To attach the smoothening pad with the footing the footing is placed in the pocket of the smoothening pad and when the end of the footing reaches the bottom of the pocket the arms of the end of the footing are pressed together so that they pass through the opening on the bottom of the pocket. Once the protrusion or tooth or lug at the end of the arm of the footing passes through an opening on the bottom of the pocket, the arms on the end of the footing, due to the flexibility of the material, move back to the initial position and the protrusion or tooth locks behind the outer side of the bottom of the pocket (behind step 192). This ensures that the smoothening pad is fixed securely to the footing. To remove the smoothening pad from the footing the arms at the end of the footing must be pressed towards each other so that the teeth of the arms disengage from behind the step (outer side of the pocket bottom), making it possible to move the arms through the opening on the bottom of the pocket.

Figs 25A, 25B, 25C and 26 show the smoothening pad 15 integrated with the applicator footing. The shape of the head 202 of the footing 14 matches the shape of the lower surface of the smoothening pad and several openings 201 have been provided in the head of the footing. The openings can be conical, so that the conicality of the openings decreases, starting from the lower surface of the footing towards the upper surface of the footing (smoothening pad rests on the upper surface). Smoothening pad 15 is formed on the footing by pressing or silicone moulding, whereas the elastic material used for making the pad passes through the openings in the head of the footing and upon solidification of the material the pad attaches firmly to the footing. Also, the slight conical shape of openings, as seen from the opposite side of the footing, provides an even stronger fastening of the smoothening pad to the footing, as the elastic material fills the conical openings upon moulding of the pad and after solidification the conical "plugs" in the openings do not allow the pad to separate from the footing.

Figs 12 to 17 show the locking system 50 of the raised part 3, to be attached into the retainer 13 on bed of the applicator, which allows to fix the raised part 3 in the working position. Locking system 50 features a frame-shaped locking device 51 , which locks the raised part 3 to the bed 2, specifically to the channel 13 of the retainer. The upper part of the frame-shaped locking device 51 is reinforced because the user needs to press here in order to release the raised part of the applicator from the working position. The frame is attached to the raised part by its sides (i.e. the raised part remains within the frame) with an axle around which the frame is rotatable. A tooth is provided in the lower part of the frame for locking the rotatable part into working position. Pressing the raised part 3 down to the channel 13 locks the tooth 55 on the locking device 51 into the tooth 56 on the bed 2 by way of a spring (not shown). A spring or similar pressure element is required to ensure sufficient locking. To release the tooth 55 of the raised part 3 from the tooth 56 on the bed, the upper part of the locking device 51 is pressed in the direction shown on Fig 12, which then releases the tooth 55 from the tooth 56 on the bed 2.

Figs 14 to 19 show various views and structures of the applicator according to the invention that describe the connection of the applicator support with the bed. They describe also the connection of the footing on the sled. Figs 20A and 20B show attachment of the applicator to the adapter nozzle attached to the nozzle of the sealing material tube. Adapter nozzle 60 is necessary for the applicator according to the invention to be used with different sealing material tubes because different countries use different dimensions. E.g. Europe uses one type of dimensions for sealing material tube nozzles, while United States have different dimensions for sealing material tube nozzles. Adapter nozzle is attached to the nozzle of the sealing material tube and the applicator is in turn attached to the adapter nozzle. To lock the applicator on the adapter nozzle, there is a locking pin 61 on the side of its upper end and there is a locking groove 62 in the applicator collar 1 1 the structure of which corresponds e.g. to the bayonet mount, which is known in the state of the art. There is a slit 63 on one side of the adapter nozzle, e.g. on the side where the locking pin is located, which reaches to the locking pin. That allows to attach the adapter nozzle to the nozzle of the sealing material tube (which is generally conical) in a fixed manner; when pressing the adapter nozzle to the tube nozzle the slit allows the adapter nozzle walls to move apart so that a firm locked attachment is formed. The upper end of the adapter nozzle is split throughout so that the longitudinal plane of the upper slit 64 is perpendicular to the longitudinal plane of the slit 63 in the lower part of the adapter nozzle and the upper slit bottom reaches the upper end/bottom of the lower slit. Upper slit is necessary because when the applicator collar is attached to the adapter collar, a locked attachment would be formed between the upper part of the adapter nozzle and collar.

Figs 33 to 34 show an applicator that can be attached with existing sealing material guns 70, e.g. silicone guns that constitute a frame 71 into which the silicone tube is inserted. There is an opening 72 in the front part of the frame for the nozzle of the silicone tube, and at the back part there is a plunger with a footing 73 (footing is not shown), which is pressed against the bottom of the tube moving inside the silicone tube with the help of an assembly 74 consisting of a handle, trigger, plunger rod, spring and plunger lock. Pressing the trigger of the silicone gun moves the plunger into the tube and silicone is pressed out of the tube nozzle. The front part of the silicone gun generally features a round protruding part 75 on the frame around which the applicator according to the invention can be attached by using the ring-shaped clamp 76 attached to the applicator base, which replaces the tubular collar 1 1 of the applicator. The clamp 76 is ring-shaped and there is an interruption in its lower part, so that two grips would be provided that attach around the round protruding part/step 75 on the front of the silicone gun. The internal diameter of the ring-shaped clamp is normally smaller than the diameter of the protruding part, so that when placing the clamp on the protruding part the grips of the clamp move due to the elasticity of their material (plastic) away from each other so that a fixed connection is provided of the clamp and together with it of the applicator around the protruding part on the front part of the frame of the silicone gun.

The applicator for smoothening the viscous sealing material comprises the attachment portion or base 2, attached to the sealing material tube, which is made up of the conical pipe collar 1 1 that is attached to the nozzle of the tube of viscous material and the support 12 of the smoothening pad, whereas the support 12 is in the channel 13 into which by way of an axle is attached a rotatable or raised part 3 in which there is a linearly movable footing 14 that is attached to the sled to which a smoothening pad 15 is fixed, whereas there is a slit at the end of the footing and on two sides of it there are arms, and to the upper side of the applicator pad there is attached a pocket into which said arms are intended to enter for the attachment of the pad with the footing on the applicator sled 14. At the ends of footing arms there is provided a step, which is intended, after the protrusion of the arms through the opening on the face of the pad pocket, to attach said arms behind the front edge of the pad pocket. A raised part locking system is attached to the raised part, which is made up of a frame-shaped lock that fixed from the centre of the frame to the raised part by way of an axle, whereas there is a tooth on the lower edge of the support on the lock frame, which is intended to be attached behind the tooth on the support, and there is a spring, which is intended for pressing the lock frame tooth behind the tooth of the support so that the raised part of the applicator along with the sled, footing and pad would be fixed in the applicator working position.

In alternative solutions the shape of the pad has been altered according to the desired smoothening grade or the material used for sealing the corners/surfaces.

Applicator is used as follows. The pad is selected for the applicator according to the finished surface (a smooth surface pad is used for smooth surfaces, for corners either the general finishing pad or fine finishing pad is used). The pad is attached to the footing of the applicator. Then, the applicator is attached to the nozzle of the tube of viscous material (that can be done also before attaching the pad to the footing) and to start the work the raised part of the applicator is rotated around the axle that is attached to the support into the working position, i.e. the pad is directed towards the finished surface. Thereby, the tooth of the locking device of the raised part is locked to the tooth on the support.

While the material that is used for finishing is pressed out of the tube of viscous material, the applicator is slid along the plane or wall-wall corner or ceiling-wall corner. Due to the elastic material of the pad (e.g. silicone) the surface of the viscous material is smoothened and the excess material is removed into a cavity in the centre of the pad or directed back to the finished surface. The excess viscous material can be brushed out or removed by simple means from the cavity in the centre of the pad.
