ROLLING STAND WITH BRAKE

For example, towel paper is commonly sold in packages in which the towel paper is wound on a cardboard core made of cardboard tube. A cut hole has been made in the towel to dispense the use.

5 For practical reasons, it is best to place the roll in a suitable rack. If the rack is not equipped with an anti-rotation brake device, it requires the cooperation of both hands when picking up the roll paper. An easy-to-dispense roll rack saves considerable towel paper 10 and time ·

For example, racks are known in which the paper roll is pressed by a flap provided with a spring. Such solutions are complex, easily damaged, and the braking force changes.

There are also racks in which the roll is pressed from the ends of the roll 15 so that it rotates under a certain resistance.

Uncertainties have been observed in these solutions and the frictional force varies. A solution in which a roller is placed on a shaft fixed to the frame, which is pressed either by gravity or by a spring-loaded brake disc, is previously known. However, in these solutions, changing the roller is slow and difficult.

Finnish patent publication No. 66760 discloses a solution in which the system consists of a brake disc and two suspension-25 bracket parts extending to the cardboard core of the paper roll. When changing the paper roll, the suspension handles must be pulled outwards and at the same time the brake disc must be raised. The procedure requires both hands, allowing the roller to easily fall to the floor. Putting a new roll in the rack is also tricky.

30 Norwegian Patent Publication No. 16160 discloses a gravity-operated braking device as part of a paoer wetting system. This solution is complex and susceptible to interference because it includes a separate wall-mounted frame with complex grooves, a separate weight section whose sole function is to brake the paper web, and a separate shaft.

Norwegian Patent Publication No. 56493 discloses a roller stand in which a plate is attached to the wall, to which a U-shaped arm is attached and articulated, which also supports the roller at both ends. The arm acts as a paper path cutter. Since the arm 5 is eccentrically mounted relative to the rest of the arm mass and even one or both ends of the arm engage the roller, the arm often remains attached to the roller, so that the roller does not rotate and thus the device does not work.

Norwegian Patent Publication No. 112173 discloses a roller-10 stand in which two overlapping holes are made in the wall-mounted U-shaped support plate, inside which the brake disc guide rod moves. Attached to the support plate is a rod or tube around which the roller rotates. The roller stand is somewhat complicated. Because the handlebar goes through the two holes, there is always a risk that the handlebar will get stuck in the holes due to its eccentric position relative to the handlebar and the brake will stop working ·. This roller stand cannot be placed under a cabinet, for example.

It is an object of the present invention to obviate the described disadvantages and shortcomings. Its features are apparent from the claims.

Figures 1 and 2 show a solution of the invention.

In Fig. 1, part (1) is a suspension bracket fastener, part (2) is a suspension bracket which is mounted at its upper end on a fastener 25 (1) and forms at its lower end a bearing of a paper roll (5) of cardboard. The end of the suspension bracket (1) is bent (3) to guide the V paper roll. Figures 1 and 2 show a brake disc (4) with a hole (Θ) into which the suspension bracket with a loose fit fits. The suspension bracket (2) is shaped to fit loosely in the hole (Θ) in the cross-section 30 of Fig. (2) so that the brake disc (4) moves easily and the lateral controllability is sufficient. The roller stand with a brake works in such a way that when the paper (7) is pulled, the roller (5) rotates with the brake.

Selecting the appropriate weight of the brake disc will cause the paper to unload 35 evenly without breaking. The cutting of the paper is performed with a sloping downward angle. The roller (5) can be easily replaced by lifting the brake disc (4) with one hand and removing and replacing the roller (5) with the other hand.

Claims (2)

3 78387 PATENT CLAIM A roller holder with a brake for dispensing towel paper or the like for dispensing around a tubular cardboard core (6) for a round roll of paper (5) formed by a suspension bracket part (2) supporting both the roll (5) and the brake disc (ή) and most preferably bent U-shaped, in which one U-shaped mandrel is formed by a bending (3) part entering the cardboard core (6) of the paper roll (5) for aligning the roll (5) and the other is suitably mounted on the fastener (1) and the brake roller plate (A) , the mass of which is chosen so that the braking frictional force formed partly between the paper (7) and the brake disc (A), partly between the lower end of the suspension bracket and the cardboard core (6) is suitable for discharging the paper (7) or the like with a steady pull, but can be easily broken at its cutting point by a slight oblique jerk, and the roller (5) is replaced by lifting the brake disc (4) upwards with one hand and removing 1a and by changing the roller (5) with one hand, characterized in that the cross section of the bracket part (2) and the hole (Θ) of the brake disc (4) are shaped to fit together so that the brake roller disc (4) can move easily vertically and thus , that the brake disc (4) is sufficiently guided horizontally.
