FIELD OF THE INVENTION
The present invention is related to a holder for rolled papers. Specifically, the present invention is related to a standing holder for kitchen roll paper/kitchen roll towel, toilet roll paper/toilet roll towel.
BACKGROUND OF THE INVENTION
A paper roll holder is a device or fixture designed to hold and dispense paper rolls. It is commonly used in various settings such as kitchens, bathrooms, offices, and workshops. The primary function of a paper roll holder is to provide a convenient and organized way to dispense paper, typically in the form of paper towels, toilet paper, or other types of rolled paper products. Usually, these paper roll holders are provided with tension mechanisms within the holder, ensuring a controlled unwinding of the paper and allowing the user to use the desired amount while keeping the remaining paper securely in place. However, these tension mechanisms can only provide single resistance force and single response time against the unwinding of the rolled products which are commercially available in various types in terms of dimension, i.e., the length of the individual sheet to be torn off. It shall be understood that when these tension mechanisms work with rolled products in different dimensions, the resistance provided to oppose the unwinding action maybe faster, slower, stronger, or weaker than required, the sheet of material to be torn may be broken off before it should have been torn along the dotted tear line.
The present invention seeks to address issues of these mechanisms lack capability to adjust its resistance force and response time, or at least to provide an alternative to the public.

FIGS. 1 and 2 show a first embodiment of the present invention. It comprises a rod member 100 and a base member 200, which are connected with each other.
FIG. 3 is an exploded view of the first embodiment. It shows that the rod member 100 comprises a first rod 102, a connector 104, and a second rod 106. Referring to FIGS. 2-3, it shall be understood that the first rod 102 and the second rod 106 are elongate and hollow, and that the connector 104 is T-shaped and has an enlarged portion 104A and an elongate portion 104B. The size and shape of the enlarged portion 104A fits well to the internal cavity of the first rod 102, such that the connector 104 is configured to be snugly mounted/disposed in the internal cavity of the first rod 102. Preferably, the connector 104 is made of resilient material. The size and shape of the elongate portion 104B fits well to the internal cavity of the second rod 106, such that the elongate portion 104B is configured to be snugly mounted in the internal cavity of the second rod 106. The assembly of the first rod 102, the connector 104, and the second rod 106 provides an advantage that the assembly is less likely bendable when comparing with a single long rod having smaller moment of inertia. The rod member 100 provides a reinforcement effect when comparing with a single long rod. In this context, “hollow” means the rod can be configured to partially hollow along its longitudinal axis or thoroughly hollow along its longitudinal axis. It shall be understood that the rod member 100 is configured to fit most of the commercially available kitchen roll paper/kitchen roll towel, toilet roll paper/toilet roll towel. In particular, the diameter of the rod member 100 fits well to the central tube of these products.

FIG. 4 shows a sectional view of the base member 200 of the first embodiment, which clearly shows the connection between these components.
FIGS. 5A-5C show the housing 204 in different views, in which FIG. 5A is a perspective top view, FIG. 5B is an elevation view, and FIG. 5C is a bottom view. It shows that the housing 204 has a central bore 204A with a plurality of channels 204C, in cylindrical profile, around the central bore 204A; an aperture 204B at a portion of the perimeter of the housing 204; and two female fasteners 204D, in cylindrical profile, arranged on the diameter of the housing 204. It shall be understood that the configuration of the components is for illustration only, and shall not be construed as limitation to the present invention.
FIG. 6 shows the assembly between the housing 204, the weight 208, and a male fastener 222, such as a bolt or a stud. It can be seen that the weight 208 is provided with a central bore 208A, an aperture 208B at a portion of the perimeter of the weight 208, and a pair of apertures 208C arranged on the diameter of the central bore 208A. The assembly in FIG. 6 is formed by first aligning the weight 208 over the housing 204, in which the aperture 208B aligns with the aperture 204B and the apertures 208C align with the female fasteners 204D. After alignment, the weight 208 is then received in the housing 204. Next, the male fastener 222 is then engaged with the female fastener 204D through the aperture 208C.
FIG. 7 shows the first receptacle 210 with different views, in which FIG. 7A is a perspective top view, FIG. 7B is a perspective elevation view, and FIG. 7C is a sectional view along the axis AA in FIG. 7A. The first receptable 210 is provided with a central bore 210A and a circumferential surrounding wall 210B. Circulating around the central bore 210A is a first standing wall 210C. Between the first standing wall 210C and the surrounding wall 210B is a second standing wall 210D. The position of the second standing wall 210D defines a first cavity between the first standing wall 210C and the second standing wall 210D, and a second cavity between the second standing wall 210D and the circumferential surrounding wall 210B. In the second cavity, a plurality of ridges extending therein in a direction from the second standing wall 210D to the circumferential surrounding wall 210B. Referring to FIG. 7B, the ridge 210E has a first end connecting with the second standing wall 210D and a second free end. There is a spacing 210F between the second free end and the surrounding wall 210B. At the bottom side of the first receptacle 210, there is provided with a pair of protruding fingers 210G. As illustrated in FIG. 7C, the second standing wall 210D is taller than the ridges 210E, which defines a step between the second standing wall 210D and the ridges 210E. FIG. 7C shows that the central bore 210A comprises an upper bore 210H and a lower bore 210J. Together with FIGS. 7B and 7C, it can be seen that the upper bore 210H is hexagonal shaped.
FIG. 8 shows the disc 214 with different views, in which FIG. 8A is a perspective top view, FIG. 8B is a perspective bottom view, and FIG. 8C is a side view. The disc 214 is a ring-shaped plate having a central cavity. On the top side of the disc 214, the perimeter edge of the disc 214 is provided with a plurality of crests 214A (or ramps). In other words, on the bottom side of the disc 214, the perimeter edge of the disc 214 is provided with a plurality of troughs 214B. The central cavity of the disc 214 is dimensioned to correspond to the size and shape of the second standing wall 210D of the first receptacle 210, such that the disc 214 can pass through the second standing wall 210D of the first receptacle 210 and sit on the ridges 210E of the first receptacle 210 when assembling the disc 214 to the first receptacle 210. It can be seen that the central cavity of the disc 214 is hexagonal, which corresponds to the shape defined by the second standing wall 210D. Due to this arrangement, it shall be understood that the disc 214 is difficult to move about the second standing wall 210D. The disc 214 is only able to move upwards and downwards, along the longitudinal direction of the rod member, with the assistance of the resilient member 212 which can be biased in the longitudinal direction of the rod member.
FIG. 9 shows the rotation member 216 with different views, in which FIG. 9A is a perspective top view, FIG. 9B is a perspective bottom view, and FIG. 9C is a sectional view in its longitudinal plane. The rotation member 216 has a first portion 216A and a second portion 216B. The first portion 216A adapts in a form of hollow cup having an open-bottom, a top-plate 216A1, and a circumferential wall 216C. The second portion 216B is a hollow bushing extending through the top-plate 216A1 of the first portion 216A, such that the top-plate 216A1 is provided with a central cavity. The second portion 216B has two parts, the first part is outwardly exposed on the top-plate 216A1 of the first portion 216A and the second part is disposed in the internal cavity of the first portion from the underside of the top-plate 216A1 of the first portion 216A. As shown in FIG. 9B, the second part of the second portion 216B can be seen in the internal cavity of the first portion 216A, i.e., the underside of the top-plate 216A1 of the first portion 216A. FIGS. 9B-9C shows that the underside of the top plate of the first portion 216A is provided with a plurality of crests 261D and trough 216E alternately arranged. Preferably, the crests and troughs are radially formed continuously around the second part of the second portion 216B. More preferably, the crests and troughs are formed in a form of serpentine.
FIG. 10 shows the assembly between the rotation member 216, the disc 214, the first receptacle 210, and the resilient member 212. It shows that the second part of the second portion 216B is received in the cavity between the first standing wall 210C and the second standing wall 210D of the first receptacle 210, and that the circumferential wall 216C of the first portion 216A is received in the spacing 210F of the first receptacle 210. Due to this arrangement, the rotation member 216 rotates with respect to the first receptacle 210. It shows that the resilient member 212 sits on the ridges 210E of the first receptacle 210 and is between the ridges 210E and the disc 214.
FIGS. 11A-B show the engagement and operation between the rotation member 216 and the disc 214. For the sake of brevity, the rotation member 216 is shown in sectional view showing the crest 216D1 and troughs 216E1, 216E2. FIG. 11A shows that the crest 214A1 of the disc 214 engages with the trough 216E1 of the rotation member 216. FIG. 11B shows that the crest 214A1 of the disc 214 engages with the crest 216D1 of the rotation member 216.
FIGS. 12A-12C shows the stopper 218, in which FIG. 12A is the perspective elevation view, FIG. 12B is a perspective bottom view, and FIG. 12C is a sectional view along the axis BB in FIG. 12A. The stopper 218 is in cylindrical profile and is provided with an upper portion 218A, a middle portion 218B, and a lower portion 218C. The perimeter of the upper portion 218A and the middle portion 218B are circular, and the dimension of the cross section in traverse plane of the upper portion 218A is larger than that of the middle portion 218B. The perimeter of the lower portion 218C is for example hexagonal shaped. In one embodiment, the dimension of the cross section in traverse plane of the lower portion 218C is the least among the upper portion, the middle portion, and the lower portion. It is advantageous to configure the shape of the perimeter of the lower portion 218C to be substantially the same as the shape of the upper bore 210H of the first receptacle 210. It is further advantageous to configure the shape of the upper bore 218D to be substantially the same as the shape of the perimeter of the second rod 106.
FIG. 13 shows the assembly between the assembly in FIG. 10 with the stopper 218 and a fastener 224, in which the lower portion 218C of the stopper 218 is received in the upper bore 210H of the first receptacle 210 through the central cavity of the top-plate 216A1 of the first portion 216A, and the fastener 224 is fasten to the lower bore 218E of the stopper 218, thereby the stopper 218 is secured to the first receptacle 210. It shall be noted that the upper portion 218A of the stopper 218 does not engage with the cavity of the first part of the second portion 216B of the rotation member 216, therefore the rotation of the rotation member 216 about the stopper is not limited.
Referring to FIGS. 10, 11, and 13, the resilient member 212 is disposed between the ridges 210E of the first receptacle 210 and the disc 214. Assuming that the assembly in FIGS. 11A and 11B shows the rotation member 216 and the disc 214 in FIG. 13, then it shall be understood that the resilient member 212 is considered as relaxed in FIG. 11A when comparing with that in FIG. 11B. On the contrary, the resilient member 212 is considered as compressed in FIG. 11B when comparing with that in FIG. 11A. In FIG. 11A, the crest 214A1 of the disc 214 acts upon the trough 216E1 of the rotation member 216, thereby the resilient member 212 is relatively relaxed. When the rotation member 216 rotates further, for example from FIG. 11A to 11B by anti-clockwise rotation, the crest 214A1 of the disc 214 acts upon the crest 216D1 of the rotation member 216, thereby the resilient member 212 is relatively compressed.
With arrangement described above, in particular the arrangements in FIGS. 11A and 11B, it shall be understood that when a roll of kitchen roll paper is mounted to the paper towel holder of the present invention by passing the tube of the kitchen roll paper through the rod member 100, the state of the rotation member 216 and the disc 214 shall be in the state as shown in FIG. 11A, i.e., the crest 214A1 of the disc 214 is received in the trough 216E1 of the rotation member 216, and the resilient member 212 is relaxed in the longitudinal direction of the rod member.
Referring to the figures, it shall be understood that when the tube of the kitchen roll paper is passed through the rod member 100, the internal surface of the tube engages closely with the outer surface of the rod member 100. When a user starts to roll the kitchen roll paper that is mounted to the rod member 100, the rolling action performed by the user leads the rotation member 216 rotates about the rod member 100 which is snugly fitted to the rotation member 216 as described above. Therefore, when a user starts to roll the kitchen roll paper that is mounted to the rod member 100, the kitchen paper roll, the rod member 100, and the rotation member 216 unitary rotate about the stopper 218, and there is rotation of the rotation member 216 with respect to the disc 214, for example the rotation member 216 rotates anti-clockwise, a state changing from FIG. 11A to 11B. During such anti-clockwise rotation, it shall be understood that the crest 216D1 of the rotation member 216 slides upwards to meet the crest 214A1 of the disc 214, thereby compressing the resilient member 212. When the rotation member 216 in FIG. 11B continues to rotate further in anti-clockwise, the crest 216D11 of the rotation member 216 slides downwards, and then the trough 216E2 meets the crest 214A1 of the disc 214, thereby relaxing the resilient member 212. In this example, the rolling action performed by a user triggers the rotation member 216 starts to slide over the disc 214 from the trough 216E1 to the trough 216E2. When the crest 214A1 of the disc 214 is received by the trough 216E2 of the rotation member 216, thereby providing a resistance against the rolling action. It shall be understood that the resistance described above is related to the compression intensity of the resilient member 212, and the time for the resilient member 212 to bounce off. During the rolling action, a sheet of kitchen paper is unwinding from the roll. However due to the resistance described above, the rotation of the kitchen roll paper is limited and thus a sheet of kitchen paper is unrolled with a length that is approximate to a predefined length to be torn determined by the dotted tear line between each sheet of kitchen paper. It allows the user to tear the unwound kitchen paper easily along the dotted tear line.
It shall be understood that the paper towel holder of the present invention is applicable to fit most of the commercially available rolled products such as kitchen roll paper/kitchen roll towel, toilet roll paper/toilet roll towel. In these products, the width of each sheet of material to be torn is different. If resistance provided to the rolling action is faster or stronger than required, the sheet of material to be torn may be broken off before it should have been torn along the dotted tear line. To cater the need to provide said resistance with different intensity and with different response time, the present invention provides convenience to user to adjust the fastening strength of the fastener 224 to the stopper 218.
The use of the fastener 224, in the assembly described above, provides a technical advantage in that the fastener 224 can control the distance between the underside of the top-plate 216A1 of the rotation member 216 and the top edge of the ridge 210E. Specifically, the distance between the crest 261D (or the trough 216E) of the rotation member 216 and the top edge of the ridge 210E. Referring to FIG. 13, it shall be understood that when the fastener 224 is more rigidly fastened to the stopper 218 (the longer region of the fastener 224 inserted into/threaded to the lower bore 218E), the distance h becomes shorter, such that the springy effect provided by the resilient member 212 is smaller. On the contrary, when the fastener 224 is less rigidly fastened to the stopper 218 (the shorter region of the fastener 224 inserted into/threaded to the lower bore 218E), the distance h becomes longer, such that the springy effect provided by the resilient member 212 is stronger. With a stronger springy effect, it shall be understood that compression intensity of the resilient member 212 is stronger and the time for the resilient member 212 to bounce off is shorter, thereby the resistance provided to the rolling action is stronger and faster. It shall further be understood that the fastener 224 can adjust the compression intensity of the resilient member 212 and the bounce-off time of the resilient member 212.
FIG. 14A-14B shows the cover 220 which is configured to be a ring-shaped plate having a central cavity. As seen, a plurality of legs 220A outwardly extends from the underside of the ring-shaped plate. The legs 220A are dimensioned receivable by the channels 204C.
As seen in FIGS. 3, 4 and 15, the lid 206 is provided with a central aperture through which part of the stopper 218 and the rotation member 216 are outwardly exposed.
