[0001] The present invention relates to a type of houseware, and particularly to a roll
holder for dispensing rolled materials.
[0002] Kitchen materials such as foil, paper, plastic film and so on are generally wrapped
around a hollow tube and a tooth-shaped score line is disposed every certain distance
thereon. The structure makes it easy to tear the rolled material at the score line
after the material is pulled out. The tear is smooth. Because of these characteristics
rolled materials are widely used in everyday live. There are various types of roll
holders for receiving rolled materials, which are different in appearance, but similar
in structure; that is, a shaft of the holder is an elastic telescopic shaft, and as
a rolled material is inserted, the shaft passes through the hollow shaft of the roll,
and is then fastened on shaft holes at both sides of a body. A common design defect
of this kind of roll holder is that the roll will drop out after the rolled material
is pulled out to a certain length; additionally the rolled material must be pulled
with both hands, which make use somewhat inconvenient.
[0003] To overcome deficiencies of prior art, it is one objective of the invention to provide
a roll holder by means of which paper and other materials may be dispensed and thorn
off in a one hand operation.
[0004] The invention is implemented as follows. The roll holder comprises a body
1 and a shaft
2. The body
1 comprises a left stop-plate
3, a right stop-plate
4, and a wall plate
5. A pair of runners
6 symmetric with each other is disposed on the left stop-plate
3 and the right stop-plate
4. A front portion
21 of the runner
6 is higher than an end portion
22 thereof. Both ends of the shaft
2 are rotably or rollingly attached to the runners
6 at both sides of the body
1, respectively. A protrusion
7 is disposed on the body
1 parallel to the shaft
2.
[0005] The runner
6 comprises a slidway
8 and a connector
9. An angle formed between the centerline of the connector
9 and that of the slideway
8 is greater than or approximately equal to 90 degrees, so as to prevent the shaft
2 from detaching from the body
1. The shaft 2 is capable of being detached from or attached to the body
1 via the connector
9.
[0006] The runner
6 is a groove 10 with a circularly closed wall. The shaft
2 is an elastic telescopic shaft.
[0007] A roll
11 for holding rolled paper and other materials is disposed on the shaft
2. The width of the roll
11 is less than the distance between the left stop-plate
3 and the right stop-plate
4. The shaft
2 passes through a hollow tube
20 on the roll
11, and is fixed on the body
1 via the connector
9.
[0008] A protruding portion of the protrusion 7 is contacted with a part of an outer edge
of the roll
11.
[0009] A stop slideway
19 is disposed at the top of the body
1. The left stop-plate
3 and the right stop-plate
4 are respectively appended on and rollingly attached to the stop slideway
19. The runner is an inner groove
16. The end portion of the shaft
2 is fastened in and rollingly attached to the inner groove
16.
[0010] A pair of supporting plates
12 are respectively disposed on the left stop-plate
3 and the right stop-plate
4. The distance between a front of the supporting plate
12 and the wall plate
5 is less than that between the connector
9 and the wall plate
5.
[0011] A cover
13 is disposed in front of the roll holder. Both ends of a cover shaft
14 of the cover
13 are rotably attached to a pair of shaft holes
15 at both sides of the front of the supporting plate
12.
[0012] Advantages of the invention include the ability to tear and/or cut a rolled material
disposed in the roll holder with one hand only, which is made possible by means of
the mobile shaft structure cooperating with the protrusion on the body and combining
the slideway with the shaft, which makes the use very convenient.

[0032] First embodiment: Now referring to Figs.
1-6, a roll holder comprises a body
1 and a shaft
2, and the body
1 comprises a left stop-plate
3, a right stop-plate
4 and a wall plate
5. A pair of runners
6 symmetric with each other are disposed on the left stop-plate
3 and the right stop-plate
4; and the front portion
21 of the runner
6 is higher than the end portion 22 thereof. Both ends of the shaft
2 are rotably or rollingly attached to the runners
6 at both sides of the body
1, respectively. A protrusion
7 parallel to the shaft
2 is disposed on the body
1.
[0033] As shown in Fig.
4, the runner
6 comprises a slideway
8 and a connector
9, and an angle between a centerline of the connector
9 and that of the slideway
8 is greater than or approximately equal to 90 degrees, so as to prevent the shaft
2 from detaching from the body
1, which may cause the roll
11 to drop when a rolled material is pulled out of the roll holder. The shaft
2 is capable of being detached from or attached to the body
1 via the connector
9. As shown in Fig.
16, the roll
11 is disposed on the shaft
2, a width of the roll
11 is less than a distance between the left stop-plate
3 and the right stop-plate
4, and the shaft
2 passes through a hollow tube
20 on the roll
11, and is fixed on the body
1 via the connector
9.
[0034] As shown in Figs.
16 and
17, a protruding portion of the protrusion
7 is contacted with a part of the outer edge of the roll
11. Referring to Fig.
6, a pair of supporting plates
12 is disposed on the left stop-plate
3 and the right stop-plate
4, respectively. The distance between a front of the supporting plate
12 and the wall plate
5 is less than that between the connector
9 and the wall plate
5. The cover
13 is disposed in front of the roll holder. Both ends of a cover shaft
14 of the cover
13 are rotably attached to a pair of shaft holes
15 at both sides of the front of the supporting plate
12.
[0035] The first embodiment of the invention operates as follows: as the rolled material
is inserted, the shaft
2 passes the hollow tube
20 of the roll
11, and then both ends of the shaft
2 are disposed into the slideway
8 via the connector
9 at both sides of the body
1. It should be noted that a head of the roll
11 is disposed in an outward direction of the body
1. As the rolled material is drawn, the head is pulled in the horizontal direction;
at this time the outer edge of the rolled material is not contacted or releasingly
contacted with the protrusion
7, which makes it easy to pull out the rolled material to a required length. As the
rolled material is to be cut or torn, the roll
11 is vertically pulled down; at this time the roll
11 forces the shaft
2 to generate a downward and inward component force, which causes an outer edge of
the roll
11 to be tightly contacted with the protrusion
7, and thereby the roll
11 is fastened and the rolled material is easily torn or cut. The process of pulling
and tearing or cutting the rolled material from the roll
11 may be done with one hand only.
[0036] Second embodiment: As shown in Figs.
7 and
8, in a second embodiment of the invention, the runner comprises no connector, and a
pair of circularly closed grooves
10 symmetrical to each other is disposed on the left stop-plate and the right top-plate.
Both ends of the shaft
2 are capable of smoothly sliding on the grooves
10. Meanwhile, the shaft
2 employs a similar telescopic shaft as in prior art solutions for inserting rolled
material. In other aspects this embodiment is the same as the first embodiment.
[0037] Third embodiment: Referring to Figs.
9, 10 and
11, in the third embodiment of the invention, a stop slideway
19 is disposed at the top of the body
1, the left stop-plate
3 and the right stop-plate
4 are respectively appended on the stop slideway
19, and slide thereon. The shaft
2 is divided into a left half-shaft
17 and a right half-shaft
18, and a hollow tube
20 of the roll
11 is received between the two half-shafts (not shown). The runner 6 is an inner groove
16, and an end portion of the shaft
2 is rollingly attached to and fastened in the inner groove
16. As shown in Fig.
9, in other aspects this embodiment is the same as the first embodiment.
[0038] Fourth embodiment: As shown in Figs.
12-15, in this embodiment, the left stop-plate and the right stop-plate of the body are
two tubes (sticks) with a U-shaped runner
6. The protrusion
7 is disposed between bottoms (namely back ends
22) of the two U-shaped runners
6. In other aspects this embodiment is the same as the first embodiment.
