Abstract

Automatic device for dispensing and applying adhesive tape onto surfaces to be joined, using ordinary adhesive tape of the kind used in offices, schools, workshops, businesses and DIY, etc., includes a casing supporting a roll of adhesive tape and a cutting blade facing a tail of unwound adhesive tape, as well as a mobile application part controlled by the user, for the direct application under pressure of the adhesive tape onto the surfaces to be joined and that cooperate, during the application and cutting phase of the adhesive tape, with [[said]] the blade which is movable due to kinematic parts for the connection with the mobile application part.

Claims

1. A dispenser device for automatically applying adhesive tape in a roll, comprising:

a casing (1) holding a roll (2) of adhesive tape;

a cutting blade (3) rotatingly supported about hinges within the housing and onto which cutting blade a tail (13) of adhesive tape, unrolled from the roll, is bears so that an edge of the cutting blade provides a cutting point of the tape;

a selectively controllable movable operating means for direct, pressure application of said tape onto surfaces to be united,

said movable operating means comprising a pushbutton (4), a rocker (5) and a tightening roller (6); and

kinematic means linking with said movable operating means and said blade,

said movable operating means cooperating with said kinematic means to rotate said blade (3), about said hinges due to an effect of the kinematic means linking with said movable operating means, so that a point where the application of the tape starts and the cutting point of the tape may coincide with a front edge of said dispenser.

2. A dispenser according to claim 1, characterized in that said pushbutton (4) comprises a shaped end (12) with a convex surface which, in the application of the tape, the convex surface gets into contact with the end of the tail (13) of the adhesive tape, detaching the end of the tail from said blade (3) and applying the end of the tail onto the surfaces to be united.

3. A device according to claim 2, characterized in that said shaped end (12) comprises a small roller (15) rotatingly supported on said shaped end.

4. A device according to claim 1, characterized in that said tightening roller (6) is rotatingly supported in a front part of said rocker (5), and is placed in a position withdrawn with respect to said blade (3) in the application of the tape while the tightening roller comes forward and surpasses said blade during cutting of the tape.

5. A device according to claim 1, characterized in that said rocker (5) is linked to said pushbutton (4), is rotatingly linked to said casing (1), and is in contrast with a bend spring (21).

6. A device according to claim 5, characterized in that said bend spring (21) is provided between a multifunction structure (17) linked to said casing (1), and another structure (23) rotatingly supported by said rocker (5).

7. A device according to claim 1, characterized in that said kinematic means comprise at least one connecting rod (9).

8. A device according to claim 1, characterized in that a surface of roller (6) comprises is textured to reduce adhesion of the tape onto said roller.

9. A device according to claim 1, characterized in that a back part of said rocker (5) comprises a tooth (18) that cooperates in an opposition relationship alternatively with a first limit structure (19), fixed on said casing (1), and with a second limit surface (20) fixed on a multifunction structure (17) linked to said casing.

10. The tape dispenser, comprising:

a casing holding a roll of adhesive tape;

a cutting blade rotatingly supported in said casing;

a rocker connected to said cutting blade;

a control button rotatingly connected to said rocker, an end of said control button being in contact with a tail of the adhesive tape;

a tightening roller positioned as a guide and rest for the tail of the adhesive tape, the roller rotatingly supported by said rocker; and

a kinematic element linking with said control button and said blade.

11. The dispenser of claim 10, further comprising:

a multi-function structure connecting two flat and parallel sides of the casing;

a roller fixed to the two sides and rotatingly supporting the roll of tape between the two sides; and

hinges rotatingly supporting said blade in said casing.

12. The dispenser of claim 11, further comprising:

at least one rod connecting said rocker to said blade;

a pin rotatingly connecting said control button to said rocker, the control button freely slidable along a surface of said multi-function structure.

13. The dispenser of claim 12, wherein said button comprises a shank rotatable and moveable around a fulcrum of said multi-function structure.

14. The dispenser of claim 10, wherein the end of said button in contact with the tail of the adhesive tape is one of a convex surface and a rotatingly supported roller.

15. The dispenser of claim 10, wherein the rocker comprises two parallel, flat shaped surfaces connected by a pin rotatingly supported by sides of the casing.

16. The dispenser of claim 10, wherein,

the tightening roller is rotatingly supported by a front side of said rocker,

a surface of said roller, in contact with an adhesive side of the tape, is textured to reduce the tape from sticking to said roller.

17. The dispenser of claim 11, wherein a rear of the rocker comprises a tooth, which tooth alternates between the limit stops of, at one end, a first limit structure fixed to the casing, and, at a second opposite end, a second limit surface of the multi-function structure.

18. The dispenser of claim 11, wherein said kinematic element comprises a spring connected between said multi-function structure and said rocker.

19. The dispenser of claim 18, further comprising:

a rotating structure supported by said rocker, and

wherein a first end of the spring connects to the multi-function structure and a second end of the spring connects to said rocker via said rotating structure.

20. The dispenser of claim 19, wherein,

from an initial resting position, user-pressure of said control button stretches the tail of the adhesive tape between the roll and the cutting blade, the adhesive tape passing above the tightening roller, the kinematic element pushing a rear part of the rocker downwards and causing said tightening roller to be in a position further forward than an end of said blade;

and

an application of the adhesive tape on an object can be started by the dispenser being positioned so that said cutting blade, to which the end of said tail is attached, is placed at the starting point on the object, and, on further pressing said control button, causes compression of the kinematic element and rotation and raising of the cutting blade,

during the raising of the cutting blade, the adhesive tape resting on the tightening roller is removed from said cutting blade and made to stick to the object, by the control button applying a pressure on the tape.
