Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 287,322 filed on December 8, 2021. The entire contents of the above application are incorporated herein by reference. Technical Field

[0003] The present application generally relates to the technical field of bathroom accessories. More specifically, the present application relates to a toilet paper dispenser. In particular, a preferred embodiment of the present application relates to a toilet paper dispenser with two rolls of products that can be moved to a single dispensing position. Background Art

[0004] There are many types of toilet paper dispensers known in the prior art. One type is a double roll toilet paper dispenser. Double roll toilet paper dispensers known in the art usually cause the second roll to rest on the shaft of the first roll after the first roll is emptied. As a result, the shaft of the first roll and the second roll rub against each other, which can cause the second roll to not rotate freely and tear the toilet paper. In addition, the second roll may fall on the first roll before the first roll is emptied and cause friction on the first roll, which can cause the first roll to not rotate freely and tear the toilet paper.

[0005] It would be desirable, therefore, to provide a toilet paper dispenser that is capable of replacing a first roll of product with a second roll of product at the same dispensing location as the first roll is emptied, while also moving the empty first roll from the dispensing location to a remote location. Thus, the second roll can be freely rotated and dispensed without being interfered with by the empty first roll. Further, the second roll is prevented from prematurely moving to the dispensing location and interfering with the first roll. Furthermore, the design of the present invention is configured to reduce tearing of the first and second rolls in either unwinding direction (e.g., clockwise or counterclockwise).

[0006] Further, it would be desirable to provide an indicator system on the toilet paper dispenser to let the user know that the second roll is in the dispensing position and the first roll is empty and needs to be refilled. Summary of the invention

[0007] The present invention is directed to a toilet paper dispenser having two rolls of product that can be moved to a single dispensing position. In addition, the toilet paper dispenser may include an indicator system to indicate when the second roll is in the dispensing position.

[0008] According to one embodiment of the present invention, a toilet paper dispenser includes a housing, an internal unit and a wheel assembly. The housing includes a top wall, a bottom wall, a first side wall, a second side wall opposite to the first side wall, a rear wall and a door opposite to the rear wall.

In addition, the indicator element includes an indicator surface visible through the indicator opening when the indicator element is in the second position.

[0010] According to yet another aspect of the present invention, the internal unit may further include a stopper bar extending between the first wall and the second wall of the internal unit below the lower roll to prevent movement of the lower roll before the lower roll is in a preset empty state. It is contemplated that the wheel unifier of the wheel assembly may include a counterweight.

[0011] According to another aspect of the present invention, each of the first plate and the second plate of the wheel assembly includes a first notch formed therein. The first notch is configured to accommodate the shaft of the lower roll and provide guidance for the lower roll during the transition of the toilet paper dispenser from the dispensing position to the disposal position. The first plate and the second plate of the wheel assembly may also include a second notch formed therein. The second notch is configured to accommodate the shaft of the upper roll and provide guidance for the upper roll during the transition of the toilet paper dispenser from the storage position to the dispensing position.

[0012] According to another aspect of the present invention, each of the first and second tracks includes an upper track extending from a first end to a second end. Each of the first track and the second track also includes a lower track extending from a first end to a second end. The upper track and the lower track are joined at a junction of the second end of the upper track and the first end of the lower track. The storage position may be provided in the upper track, while the disposal position and the dispensing position may be located in the lower track.

[0028] The invention and the various features and advantageous details described therein may be explained in greater detail with reference to the non-limiting examples described in detail in the following specification.

[0029] Throughout the specification, various terms indicating directions may be used, such as left and right, front and back, up and down, top and bottom, etc. These directions are not intended to be limiting, but are used to describe the relationship of the elements in the drawings relative to each other. It is contemplated that, unless mutually exclusive, the elements may be reversed, for example, by turning the parts over or inverting them, without departing from the scope of the present invention.

[0030] First refer to Figures 1 to 4, which shows a toilet paper dispenser 10 according to one embodiment of the present invention. The toilet paper dispenser 10 includes a housing 12 having first and second side walls 14, 16 facing each other, a top wall 18 extending between the top edges of the first and second side walls 14, 16, and a rear wall 22 extending between the side edges of the first and second side walls 14, 16 located at the rear of the housing 12. Opposite the rear wall 22 and at the front of the housing 12, the housing 12 includes a door 24. The door 24 is pivotally connected to at least one of the first and second side walls 14, 16 along a pivot point 26.

[0031] The door 24 includes an indication opening 28 formed in a front surface 30 of the door 24. As will be described in further detail below, the indication opening 28 is configured to indicate to a user that the toilet paper dispenser 10 needs to be refilled. In addition, the door 24 includes an opening 32 formed in its front surface 30 to enable an interior volume 34 of the housing 12 to be accessed.

[0032] The first and second shafts 36, 38 are disposed within the interior volume 34 of the housing 12 and are configured to each hold a roll of material, such as toilet paper. Figure 1 and Figure 2 , the first axis 36 is shown oriented toward the dispensing position 40. Figure 3 and Figure 4 , the second shaft 38 is shown in the storage position 42. Additional positions of the first and second shafts 36, 38 will be described in other descriptions of the present invention.

[0033] Now refer to Figures 5 to 9 , which shows the internal unit 44 of the toilet paper dispenser 10. Figure 1-Figure 4 As shown, the internal unit 44 is disposed within the housing 12. The internal unit 44 includes a first wall 46, a second wall 48 facing opposite the first wall 46, and a rear wall 50 extending between the first and second walls 46, 48. In an exemplary embodiment of the present invention, the internal unit 44 can be formed to include a plurality of spacing elements 52, which extend between the first and second walls 46, 48 and the first and second side walls 14, 16 of the housing 12, respectively. The spacing elements 52 are used to center the internal unit 44 within the housing 12 and to appropriately space the first and second walls 46, 48 from the first and second side walls 14, 16 to accommodate the wheel assembly 54 and its components, which will be described in further detail below.

[0034] Fig.10 A side view of the internal unit 44 is shown with the wheel assembly 54 removed to further illustrate the elements within the first and second walls 46, 48 of the internal unit 44. Specifically, Fig. 9An exemplary embodiment of the first wall 46 of the internal unit 44 is described. Although the following description is directed to the first wall 46, it also applies to the second wall 48. Each wall 46, 48 includes a track 56 formed in the wall 46 to enable the first and second shafts 36, 38 and associated rolls to move along the track 56.

[0035] The track 56 includes an upper track 58 that extends from a first end 60 to a second end 62. The track 56 also includes a lower track 64 that extends from a first end 66 to a second end 68. The upper track 58 and the lower track 64 are joined at the second end 62 of the upper track 58 and the first end 66 of the lower track 64 to form a continuous track 56. In addition, an outlet 70 extends from the track 56 near the junction of the upper track 58 and the lower track 64 to enable the shafts 36, 38 to be removed from the internal unit 44 and the toilet paper dispenser 10 for refilling with the associated rolls. As will be described below, the second shaft 38 moves along the upper track 58 to transition from a storage position 96 adjacent the first end 60 of the upper track 58 to a dispensing position 94 adjacent the junction of the upper track 58 and the lower track 64, while the first shaft 36 moves along the lower track 64 to transition from the dispensing position 94 to a disposal position 114 adjacent the rear portion of the second end 68 of the lower track 64 (see below for details). Figure 6-Figure 8 Although the dispensing location 94 may be variably located proximate the junction of the upper track 58 and the lower track 64 , it is contemplated that the dispensing location 94 is aligned with the opening 32 in the door 24 .

[0036] The walls 46, 48 of the inner unit 44 further include an opening 72 configured to receive a wheel unifier 74 of the wheel assembly 54 and sized to enable the wheel unifier 74 to move when the wheel assembly 54 rotates about the pivot point 76. It is also contemplated that the edges of the opening 72 provide blocking locations for limiting the rotational movement of the wheel unifier 74, thereby also limiting the rotational movement of the wheel assembly 54. The wheel assembly 54 includes wheel plates 78, 80 interconnected by the wheel unifier 74, and the wheel unifier 74 extends between the wheel plates 78, 80. The wheel unifier 74 is used to couple the plates 78, 80 together so that the plates 78, 80 of the wheel assembly 54 rotate together. Accordingly, the wheel unifier 74 helps prevent the wheel assembly 54 from being off-center by synchronizing the rotation and movement of the wheel plates 78, 80. In certain embodiments of the present invention, it is contemplated that the wheel unifier may include a counterweight to assist in supporting and rotating the inner unit 44 .

[0037] Each runner plate 78, 80 is disposed on the outer surface of the first and second walls 46, 48, respectively, of the inner unit 44. Therefore, each runner plate 78, 80 is disposed in the space between the inner unit 44 and the housing 12. In the exemplary embodiment of the present invention, the space between the inner unit 44 and the housing 12 is maintained by the aforementioned spacing elements 52.

[0038] Further, the profile of each wheel plate 78, 80 has a first notch 82 configured to receive the first shaft 36 and a second notch 84 configured to receive the second shaft 38. When the wheel assembly 54 rotates, the notches 82, 84 of the wheel plates 78, 80 help guide the shafts 36, 38 along the track 56 of the inner unit 44. Fig. 9 As shown, when in the intermediate position, the first notch 82 of each runner plate 78, 80 is located at the front edge of each runner plate 78, 80, and the second notch 84 of each runner plate 78, 80 is located at the top edge of each runner plate 78, 80.

[0039] Figure 5-Figure 8 Further shown is an indicator element 86 that is rotatably connected to the first wall 46 of the inner unit 44 about a pivot point 88. The indicator element 86 includes an indicator surface 90 that is visible depending on the orientation of the indicator element 86, and this and other features will be described in further detail below. Although the indicator element 86 is shown in the exemplary embodiment of the present invention as being connected to the first wall 46 of the inner unit 44, it is contemplated that the indicator element 86 may be connected to any surface of the inner unit, such as, but not limited to, the second wall 48 of the inner unit 44.

[0040] Now refer to Figure 6-Figure 8 The wheel assembly 54 is shown in a number of orientations as the upper and lower rolls on the shafts 36 , 38 transition along the track 56 , respectively. Figure 6 The wheel assembly 54 is shown in a first orientation 92. In the first orientation 92, the first shaft 36 holding the lower roll is in a dispensing position 94, and the second shaft 38 holding the upper roll is in a storage position 96. When the diameter of the lower roll is greater than a preset empty size, a stopper bar 98 extending between and adjacent the lower edges of the walls 46, 48 of the inner cell 44 prevents the lower roll from moving out of the dispensing position 94. Preferably, the preset empty size of the lower roll is in the range of 1.75 inches to 2.00 inches. More preferably, the preset empty size of the lower roll is 1.875 inches.

[0041] like Figure 6100, the indicating element 86 is oriented in its first orientation 100. In the first orientation 100, the indicating surface 90 of the indicating element 86 is not in the same plane as the indicating opening 28 of the door and is at a certain angle. Therefore, when oriented in its first orientation 100, the indicating surface 90 cannot be seen through the indicating opening 28. In addition, the indicating element 86 may include a groove 110 formed in a surface thereof. In an exemplary embodiment of the present invention, the groove 110 is formed in a surface of the indicating element 86, and when the indicating element 86 is in the first orientation 100, the surface is adjacent to the storage position 96. In addition, the groove 110 is configured to interact with the shaft 38 to maintain the shaft 38 in the storage position until the indicating element 86 is moved.

[0042] Secondly, Figure 7 The runner assembly 54 and the indicator element 86 are shown transitioning from the first orientations 92, 100 to the second orientations 102, 104, respectively. In the second orientation 102 of the runner assembly 54, the runner assembly 54 begins to rotate counterclockwise as the diameter of the roll decreases. As the runner assembly 54 begins to rotate about the pivot point 76, the upper rear edge 106 of the runner plate 78 begins to lift the rear edge 108 of the indicator element 86.

[0043] Accordingly, the indicator element 86 is rotated about its pivot point 88 into its second orientation 104. In its second orientation 104, the recess 110 of the indicator element 86 is raised and away from the shaft 38 to enable the shaft 38 to move along the track 56. Further, the indicator surface 90 of the indicator element 86 remains non-planar and at an angle to the indicator opening 28 of the door 24.

[0044] at last, Figure 8 The wheel assembly 54 is shown in a third orientation 112. Once the diameter of the lower roll on the first shaft 36 is less than the preset empty size, the wheel assembly 54 fully rotates to the third orientation 112 as the notches 82 of the plates 78, 80 direct the first shaft 36 and the associated lower roll from the dispensing position to a disposal position 114 adjacent the rear portion of the second end 68 of the lower track 64. At the same time, the notches 84 of the plates 78, 80 accommodate the second shaft 38 and the associated upper roll as they transition along the upper track 58 and direct the second shaft 38 and the associated upper roll along the track to the dispensing position 94. As described above, the wheel assembly 54 may include a counterweight or be otherwise weighted so that the wheel assembly 54 immediately rotates when the diameter of the lower roll is less than the preset empty size.

[0045] Figure 8Also shown is the indicator element 86 in the third orientation 116. Once the wheel assembly 54 begins to rotate to its third orientation 112, the indicator element 86 is able to rotate counterclockwise about its pivot point 88 so that the indicator surface 90 of the indicator element 86 is aligned and in the same plane with the indicator opening 28 of the door 24. In an exemplary embodiment of the present invention, the rear edge 108 of the indicator element 86 is configured to abut against the rear edge 108 of the wheel plate 78 when the wheel assembly 54 and the indicator element 86 are both in their respective third orientations 112, 116. When aligned with the indicator opening 28, the indicator surface 90 provides notification to the user that the upper roll and second shaft 38 are in the dispensing position and that the toilet paper dispenser 10 needs to be refilled. In different embodiments of the present invention, the indicator surface 90 of the indicator element 86 can be any number of colors, textures, etc. to indicate that refilling is required.

[0046] It is contemplated that different embodiments of the present invention may include an indicator element similar to the indicator element 86 that is rotatably connected to the second wall 48 of the internal unit 44 about a pivot point. Such an indicator element would operate in a similar manner to the indicator element 86 described above and interact with the shaft 38 and the runner plate 80 in a similar manner. In addition, an indicator opening similar to the indicator opening 28 may be formed in the housing to align the indicator surface of the indicator element in the same manner as the indicator surface 90 of the indicator element 86. In other embodiments of the present invention, a retaining element may be pivotally connected to the second wall 48 of the internal unit 44 and interact with the shaft 38 and the runner plate 80 in substantially the same manner as the indicator element 86. However, such a retaining element may not include the indicator surface 90.

[0047] Now refer to Fig.11 , which shows a shaft according to one embodiment of the present invention, for example, shaft 38. Shaft 38 includes a main body portion 130, a first extension 132, and a second extension 134 oriented along the same axis. In a preferred embodiment of the present invention, the main body portion 130 of shaft 38 can be barrel-shaped, with a diameter thicker in the middle than at the edge. Alternatively, the main body portion 130 of the shaft can be cylindrical, with a diameter in the middle that is the same as the diameter at the edge.

[0048] The first and second extensions 132, 134 extend outwardly from the body 130. In turn, the extensions 132, 134 extend through the track 56 as described above and enable the shaft 38 to pass through the track 56 of the internal unit 44 and move between positions. As shown, the extensions 132, 134 have a smaller diameter than the body 130 and are smaller in size than the width of the track 56.

[0049] At the distal ends 136, 138 of the extensions 132, 134, the shaft 38 ends in a cap 140, 142, respectively. As shown, the diameter of the caps 140, 142 is greater than their respective extensions 132, 134, and is also greater than the width of the track 56 of the internal unit 44. Thus, the shaft 38 can travel along the track 56 without shifting left or right. In addition, the T-shape of the shaft 38 allows the shaft 38 to be removed from and inserted into the track 56 only when the door 24 is open via the exit 70. Although the above description is directed to the shaft 38, it is contemplated that it can also be applied to the shaft 36 of the present invention.

[0050] In a preferred embodiment of the present invention, the toilet paper dispenser 10 is filled in the following manner: the second shaft 38 is removed from the dispensing position 94 via the outlet 70 to fill the upper roll, the second shaft 38 with the upper roll is returned to the dispensing position 94 via the outlet 70, the wheel assembly 54 is rotated to move the second shaft 38 from the dispensing position 94 to the storage position 96 and the first shaft 36 is moved from the rear disposal position 114 to the dispensing position 94, the first shaft 36 is removed from the dispensing position 94 via the outlet 70 to fill the lower roll, and the first shaft 36 with the lower roll is returned to the dispensing position 94 via the outlet 70.

[0051] Refer again Figure 3-Figure 5 In an exemplary embodiment of the present invention, the interior unit 44 may further include a lock plate 120 disposed at the top of the interior unit 44 and adjacent to the top wall 18 of the housing 12. Further, the door 24 of the housing 12 includes a lock 122 disposed on an inner surface 124 of the door 24. The lock 122 includes a latch 126 configured to interact with an opening 128 formed in the lock plate 120 to lock and unlock the toilet paper dispenser 10. In different embodiments of the present invention, the latch 126 of the lock 122 can be activated in various ways, for example, via a key or a magnet.

[0052] Although the best mode of implementing the invention contemplated by the inventors is disclosed above, the practice of the invention is not limited thereto. It is obvious that various additions, modifications and rearrangements of the features of the invention can be made without departing from the spirit and scope of the basic inventive concept.

[0053] Furthermore, the components need not be formed into the disclosed shapes or assembled in the disclosed configurations, but can be provided in almost any shape and assembled in almost any configuration. Further, all disclosed features of each disclosed embodiment can be combined with or substituted for the disclosed features of each other disclosed embodiment, unless such features are mutually exclusive.
