The present invention relates to a towel dispenser, of the type comprising a housing partially closed by a façade defining a through opening for dispensing towels.
Such towel dispensers are known. They are generally intended for dispensing stacked disposable towels that are arranged in the housing and that can be grabbed by users through the opening arranged in the façade. These towels are generally folded such that removing a towel from the stack pulls part of the adjacent towel in the stuck with it, so as to allow one towel from the stack to extend partly through the opening at all times. Thus, users do not need to plunge their hand into the housing through the opening to grab the towels, but can grab them easily owing to the end thereof protruding from the opening.
There are two ways to stack these disposable towels. A first way is intended for transverse dispensing of the towels. In order for the towels stacked in this first way to be unfolded effectively, it is important for the pulling exerted on a towel when it is removed from the stack to be exerted in a direction substantially orthogonal to the stacking direction. A second way is intended for axial dispensing of the towels. In order for the towels stacked in this second way to be unfolded effectively, it is important for the pulling exerted on a towel when it is removed from the stack to be exerted in a direction substantially parallel to the stacking direction.
Towel dispensers are known intended to dispense towels stacked in the first manner described above. These dispensers generally have a housing suitable for the stacks of towels to be able to be arranged inside this housing such that the façade faces the edge of these stacks of towels. However, these dispensers are not suitable for dispensing towels stacked in the second manner described above.
Towel dispensers are also known intended to dispense towels stacked in the second manner described above. These dispensers generally have a housing suitable for the stacks of towels to be able to be arranged inside this housing such that the façade of the dispenser faces one end of these stacks of towels. However, these dispensers are not suitable for dispensing towels stacked in the first manner described above.
The known dispensers are thus only compatible with one of the existing stacking methods. Yet depending on the region of the world that one is in, towels may only be available stacked according to the first or second method. This is particularly problematic when the dispenser is on board a vehicle required to travel large distances, such as an aircraft: indeed, during layovers, it is sometimes impossible to obtain towels stacked using a method compatible with the dispensing mode of the dispenser. This requires providing substantial inventories of towels on board the aircraft to avoid running out, which needlessly encumbers the aircraft. Additionally, when, despite these precautions, the excess towels are exhausted, it is necessary to buy boxes of towels during layovers that must be placed next to the dispenser, on the counter, which, in addition to being unattractive, is often cluttered.
One aim of the invention is thus to make it possible, using a single towel dispenser, to provide satisfactory dispensing of towels stacked in both the first and second manners described above.
To that end, a towel dispenser of the aforementioned type is provided, wherein the dispenser further comprises a holder inserted into the housing, the holder having a substantially planar base and, protruding from the base, at least one wall substantially perpendicular to the base, the base and the or each wall together defining a parallelepiped cavity for receiving a stack of towels, said cavity emerging outside the holder through a first window arranged in a first face of the parallelepiped substantially orthogonal to the base and through a second window arranged in a second face of the parallelepiped opposite the base, the holder being able to be positioned inside the housing in a first position, in which the first window faces the through opening, and in a second position, in which the second window faces the through opening.
According to specific embodiments of the invention, the towel dispenser also has one or more of the following features, considered alone or according to any technically possible combination(s):
An aircraft comprising a towel dispenser as defined above is also provided.
A method for using a towel dispenser as defined above, comprising the following successive steps:
According to one particular embodiment of the invention, the usage method also has the following feature:
Other features and advantages of the invention will appear more clearly upon reading the following description, provided solely as an example and done in reference to the appended drawings, in which:
The towel dispenser 10, shown in
This housing 12 is delimited between a bottom wall 14 (
The bottom wall 14 defines an inner face, oriented toward the housing 12, which is substantially planar. Likewise, the bottom wall 16 defines an inner face, oriented toward the housing 12, which is also substantially planar.
The façade 20 is removable in the illustrated example. To that end, it comprises reversible fastening members 26 for selectively fastening the façade 20 to the housing 12 and separating the façade 20 from the housing 12.
Towel dispenser 10 also comprises a removable holder 30 able to be inserted in the housing 10 to receive the disposable towels and facilitate the dispensing of these towels through the opening 22.
The holder 30 has a substantially planar base 32 and, protruding from the base 32, three walls 34, 36 each substantially perpendicular to the base 32, the base 32 and the walls 34, 36 together defining a parallelepiped cavity 38 for receiving a stack of disposable towels.
The base 32 is substantially rectangular. It has a first transverse edge 40, a second transverse edge 42 and two side edges 44.
The base 32 also has fastening orifices 46. Each fastening orifice 46 is a through orifice and emerges both in an inner face 47 of the base 32, opening into the cavity 38, and in an outer face 48 of the base 32, oriented opposite the cavity 38.
Each fastening orifice 46 in particular has a teardrop shape, with a first wide part 50, and a second narrow part 52 (
In the illustrated example, there are two of these fastening orifices 46, each fastening orifice 46 being located in a respective corner between the first transverse edge 40 and one of the side edges 44.
The walls 34, 36 comprise a bottom wall 34 and two side walls 36. All three protrude relative to the base 32 from a respective edge 42, 44 of the base 32, substantially perpendicular to the base 32, in a same direction. In particular, the bottom wall 34 protrudes from the second edge 42 of the base 32 and each side wall 36 protrudes from a respective side edge 44 of the base 32.
The bottom wall 34 is solid. It is generally rectangular.
Each side wall 36, also substantially rectangular, has a through slit 54 emerging both in and outside the cavity 38, this slit 54 being oriented substantially perpendicular to the base 32.
The holder 30 has no wall along a first face 56 of the cavity 38, substantially orthogonal to the base 32 and the side walls 36 and opposite the bottom wall 34, and along a second face 58 of the cavity 38, substantially orthogonal to the walls 34, 36 and opposite the base 32. The cavity 38 is therefore open on said first and second faces 56, 58 and emerges outside the holder 30 through a first window 60 arranged in said first face 56 and through a second window 62 arranged in said second face 58, the first and second windows 60, 62 communicating with one another.
The first window 60 thus extends over more than 50%, in particular more than 80% and preferably, as shown, substantially all of the first face 58.
The second window 62 extends over more than 50%, in particular more than 70% and preferably, as shown, more than 80% of the first face 56. The second window 62 does not, however, extend over all of the first face 56; indeed, the holder 30 comprises two side ribs 64 each protruding from a respective side wall from among the side walls 36, substantially in the plane of the second face 58, toward the center of the cavity 38. Each side rib 64 extends from one edge of the respective side wall 36, alongside the bottom wall 34, to the opposite edge.
The distance between the side ribs 64 is smaller than the width of a standard stack of disposable towels.
The cavity 38 has dimensions suitable for receiving stacks of disposable towels. To that end, the section of the cavity 38, considered along a plane parallel to the base 32, has dimensions slightly larger than those of the cross-section of a standard stack of disposable towels. “Slightly larger” means that the difference in dimensions is smaller than 1 cm.
Thus, the cavity 38 is suitable for receiving stacks of disposable towels stacked in a direction substantially orthogonal to the base 32. The cavity 38 is also shown in
Returning to
The plate 66 comprises a substantially planar body 70 oriented parallel to the base 32. This body 70 has a shape complementary to the section of the cavity 38; thus, in the illustrated example, the body 70 has a rectangular shape and extends from one side wall 36 to the opposite side wall 36, and from the bottom wall 32 to the first face 56 of the cavity 38.
The plate 66 also comprises, at each of its side ends, a lug 72 cooperating with the slit 54 formed in a respective side wall from among the side walls 36 to guide said plate 66 between its retracted and deployed positions. The slits 54 formed in the side walls 36 and the lugs 72 of the plate 66 thus form complementary guide means for the plate 66, the slits 54 making up guides and the lugs 72 making up slides mounted moving in said guides.
The return device 68 is, in the illustrated example, formed by two compression springs 73 each inserted between the base 32 and the plate 66 while being oriented substantially perpendicular to the base 32.
The holder 30 can be positioned inside the housing 12 in a first position, shown in
The dispenser 10 also comprises a system 74 for retaining the holder 30 inside the housing 12 in its first and second positions.
This retaining system 74 comprises a movable retaining device 76, secured to the holder 30, a first stationary retaining device 78, secured to the housing 12, and a second stationary retaining device 80, also secured to the housing 12.
The movable retaining device 76 is made up of the fastening orifices 46 arranged in the bottom wall 32.
The first stationary retaining device 78 is suitable for cooperating with the movable retaining device 76 so as to retain the holder 30 in its first position. To that end, the first stationary retaining device 78 is formed by two primary fasteners 82 fastened to the bottom wall 14 of the housing 12.
Each primary fastener 82 is closer to the front face of the housing 12 than the rear wall 16.
As shown in
Each fastener 82 is in particular formed by a rod 84 ending with a head 86 at its distal end separated from the bottom wall 14. The head 86 has a diameter, considered in a plane parallel to the bottom wall 14, smaller than the dimensions of the first wide part 50 of the fastening orifices 46 and larger than the dimensions of the second narrow part 52 of these same orifices 46. The diameter of the rod 84, still considered in a plane parallel to the bottom wall 14, is in turn smaller than the dimensions of the first wide part 50 and the second narrow part 52 of the fastening orifices 46. The rod 84 is in particular threaded and forms a screw 87 with the head 86.
Each primary fastener 82 is thus suitable for being engaged in a respective orifice from among the fastening orifices 46 and removed from this same respective orifice without disassembling any parts.
Each fastener 82 also comprises an insert 89 driven into the bottom wall 14. This insert 89 comprises a tapped orifice (not shown), complementary to the threaded rod 84 and in which said rod 84 is screwed.
When the holder 30 is in its first position, each primary fastener 82 is received in the narrow part 52 of its respective fastening orifice 46. The holder 30 is thus prevented from withdrawing by the primary fasteners 82. Furthermore, these same primary fasteners 82 prevent the holder 30 from being moved sideways or vertically.
Returning to
As shown in
Each fastener 88 is in particular formed by a rod 90 ending with a head 92 at its distal end separated from the rear wall 16. The head 92 has a diameter, considered in a plane parallel to the rear wall 16, smaller than the dimensions of the first wide part 50 of the fastening orifices 46 and larger than the dimensions of the second narrow part 52 of these same orifices 46. The diameter of the rod 90, still considered in a plane parallel to the rear wall 16, is in turn smaller than the dimensions of the first wide part 50 and the second narrow part 52 of the fastening orifices 46. The rod 90 is in particular threaded and forms a screw 94 with the head 92.
Each secondary fastener 88 is thus suitable for being engaged in a respective orifice from among the fastening orifices 46 and removed from this same respective orifice without disassembling any parts.
Each fastener 88 also comprises an insert 96 driven into the bottom wall 14. This insert 96 comprises a tapped orifice (not shown), complementary to the threaded rod 90 and in which said rod 90 is screwed.
When the holder 30 is in its first position, each secondary fastener 88 is received in the narrow part 52 of its respective fastening orifice 46. The holder 30 is thus prevented from descending by the secondary fasteners 88. Furthermore, these same secondary fasteners 88 prevent the holder 30 from being moved sideways or longitudinally.
The movement of the holder 30 from its first position to its second position will now be described in reference to
Initially, the dispenser 10 is in its first configuration, the holder 30 containing disposable towels stacked in the first manner described in the preamble. When the towels in this stack have, however, been removed from the dispenser 10 and only towels stacked in the second manner described in the preamble are available for reloading, the configuration of the dispenser 10 must be changed in order to allow the axial dispensing of the towels.
To that end, the façade 20 is first removed, as shown in
The holder 30 is then translated forward, as shown by
This disengagement step of the primary fasteners 82 from the fastening orifices 46 immediately follows the step for translating the holder 30. To that end, the holder 30 is translated upward, as shown in
The holder 30, which then moves freely, is next removed from the housing 12 (
The holder 30 is then withdrawn so as to enter the housing 12, as illustrated by
The holder 30 is next lowered, as illustrated by
The holder 30 is then filled with a new stack of towels 65. To that end, the towels of the new stack 65 are inserted into the cavity 38 through the second window 62. In so doing, pressure is exerted on the plate 66, toward the base 32, so as to bring this plate 66 back to its retracted position. Once the towels are received in the cavity 38, they are pushed outside the cavity 38, toward the second window 62, by the return device 68 of the plate 66; however, the side ribs 64 retain the towels inside the cavity 38 and prevent them from leaving under the effect of this pressure alone.
The façade 20 is lastly returned to its place, as shown in
To return the dispenser 10 to its first configuration, it suffices to carry out the aforementioned steps in the reverse order.
It is thus possible to use a single dispenser 10 to allow both an axial and transverse dispensing of towels from a stack, with an easy change of configuration between the configuration used for axial dispensing and the configuration used for transverse dispensing.
The dispenser 10 is further particularly suitable for use on board an aircraft.
Lastly, the dispenser 10 facilitates the dispensing of towels by making it possible, owing to the plate 66 and the associated return device 68, for said towels to be brought continuously closer to the dispensing opening 22.
It will be noted that the dispenser 10 may also allow use with reusable fabric towels rather than disposable towels. To that end, it in fact suffices to remove the holder 30 from the housing 12, as previously described, and to use the housing 12 to store fabric towels.
