The present disclosure generally relates to locking assemblies to lock together two elements. More particularly, the present disclosure relates to a locking assembly configured to lock together a base part and a cover of a dispenser, the base part and the cover defining together a dispensing chamber, to contain, for instance, a web material roll. The present disclosure further relates to a dispenser including the locking assembly.
Several types of web material roll dispensers exist to gradually provide a user of the web material roll dispenser with different types of web material. The most common types of dispensers dispense paper items such as paper towels and toilet paper.
In the dispenser field, locking assemblies are used to lock a base part and a cover together in a closed configuration. Several types of locking assemblies exist which include a key enabling the configuration of the locking assembly into an unlocked configuration, so as to provide access to a dispensing chamber of the dispenser, for instance to fill it with web material to be dispensed. However, the key might be lost or damaged, such an event jeopardizing the possibility of configuring the dispenser in the open configuration, and thus jeopardizing the use of the dispenser. Some other known locking assemblies comprise a pushbutton onto which pressure must be applied to configure the locking assembly into the unlocked configuration. However, it is not fully satisfactory since these dispensers are often used in public area, such as washrooms, and thus an ill-intentioned person could unlock the locking assembly, for instance to remove the web material out of the dispensing chamber.
In view of the above, there is a need for an improved dispenser comprising a locking assembly which would be able to overcome or at least minimize some of the above-discussed prior art concerns.
It is therefore an aim of the present invention to address the above-mentioned issues.

General Structure of the Dispenser
Referring now to the drawings, and more particularly to
The housing 102 comprises a base part 106 and a cover 108. The cover 108 and the base part 106 are movable relative to each other. The base part 106 has a rear portion 107 that is configured to be mounted to a supporting surface, for instance, a wall. In the embodiment shown, the cover 108 is pivotally mounted to the base part 106, in the lower portion thereof. Therefore, the cover 108 and the base part 106 are movable relative to each other between a closed configuration, in which the dispensing chamber 104 is at least partially closed, and an open configuration, as shown in
The dispenser 100 further comprises a locking assembly 110, which can be selectively and alternatively configured in a locked configuration, in which the cover 108 and the base part 106 are locked together in the closed configuration, and an unlocked configuration in which the cover 108 and the base part 106 are free from being moved relative to each other (for instance, in which the cover 108 is free from being pivoted away from the base part 106) so that the base part 106 and the cover 108 can be configured in the open configuration.
As will further be described in more details, the lock assembly 110 comprises a catch-engaging portion 112 mounted, in the shown embodiment, to the base part 106 of the dispenser 100, and a lock catch 114 mounted, in the shown embodiment, to the cover 108. The lock catch 114 is engageable with the catch-engaging portion 112 to maintain the base part 106 and the cover 108 in the closed configuration. In other words, the lock catch 114 is displaceable between an engaged configuration in which the lock catch 114 is engaged with the catch-engaging portion 112 to maintain the base part 106 and the cover 108 in the closed configuration, and a disengaged configuration in which the lock catch 114 is disengaged from the catch-engaging portion 112 for the base part 106 and the cover 108 to be displaceable relative to each other to be configurable into the open configuration. It is appreciated that, in an alternative embodiment (not shown), the base part 106 can include the lock catch 114 while the cover 108 includes the catch-engaging portion 112.
As shown in
Moreover, as shown in
The unlocking component 120 further comprises a pushbutton 140 at least partially contained in the unlocking body 130.
The locking assembly 110 is selectively configurable in a key-opening configuration wherein the pushbutton 140 is prevented from translation in the interior volume 105 of the inner casing 109 (or with respect to the housing 102) and wherein pressure should be applied directly onto the unlocking body 130 to engage the unlocking body 130 into translation in the interior volume 105 of the inner casing 109. When the locking assembly 110 is configured in the key-opening configuration, a key 180 as shown in
In other words, the locking assembly 110 is configured so that, when it is configured in the key-opening configuration, the key 180 is required to configure the locking assembly 110 in the unlocked configuration, whereas when the locking assembly 110 is configured in the pushbutton-opening configuration, no key is required to configure the locking assembly 110 into the unlocked configuration. A pressure applied on the pushbutton 140 of the unlocking component 120 is sufficient for the locking assembly 110 to be configured in the unlocked configuration.
In the following description, the terms “inner” and “outer” should be understood, unless otherwise stated, with regards to the interior volume 105 of the inner (or locking) casing 109 in which at least some of the components of the locking assembly 110 are arranged or with regards to the dispensing chamber 104 of the housing 102. In other words, the term “outer” should be understood, unless otherwise stated, as being relative to a volume outside the interior volume 105 of the locking casing 109 or as being exposed outwardly of the interior volume of the locking casing 109 (or with regards to the dispensing chamber 104 of the housing 102).
Description of the Components
A first embodiment of the locking assembly 110 is shown in
In the shown embodiment, the unlocking body 130 has a substantially frusto-conical shape having an outer end 132 (or actuation end 132), in the shape of an exposed rim, and an opposed inner end 134 (or unlocking end 134). The substantially frusto-conical shape of the unlocking body 130 converges towards the unlocking end 134. In other words, the unlocking body 130 is tapered towards the unlocking end 134. The actuation end 132 comprises an outer surface 133 that is substantially circular, in the embodiment shown. A through opening 136 is formed in the unlocking body 130 that extends between the unlocking and actuation ends 134, 132. In the shown embodiment, as represented in
The unlocking body 130 is translatable in the interior volume 105 of the inner casing 109 along an unlocking axis X1 and is configured to cooperate with the lock catch 114 along the unlocking axis X1. In the shown embodiment, the lock catch 114 is pivotably mounted to the cover 108 (to the inner casing 109 of the cover 108, in the embodiment shown, within the interior volume 105 thereof) about first and second pivoting axes X2, X2′ that both extend substantially parallel to the unlocking axis X1, the unlocking body 130 being configured to contact the lock catch 114 when translating along the unlocking axis X1 to pivot the lock catch 114 about the pivoting axes X2, X2′ into the disengaged configuration. When the lock catch 114 is configured into the disengaged configuration, the lock catch 114 is disengaged from the catch-engaging portion 112 and the cover 108 and the base part 106 can be displaced relatively to each other to be configurable from the closed configuration to the open configuration.
In the shown embodiment, the lock catch 114 comprises first and second catch portions 115, 115′ that are both pivotally mounted in the inner casing 109 respectively about the first and second substantially parallel pivoting axes X2, X2′. The first and second catch portions 115, 115′ are arranged so as to define a gap in-between, the inner end 134 (or unlocking end 134) of the unlocking body 130 of the unlocking component 120 being arranged in the gap defined between the first and second catch portions 115, 115′. It is appreciated that, in an alternative embodiment (not shown), the lock catch 114 can include only one catch portion.
Each one of the catch portions 115, 115′ includes an arm 192, 192′ pivotally mounted at a first end 194, 194′ and including a hook 196, 196′ at a second end. In the embodiment shown, the hooks 196, 196′ of the two catch portions 115, 115′ are oriented towards one another to engage the catch-engaging portion 112, which is located in-between in the closed configuration. In the embodiment shown, pins 210, 210′ protrude from a bottom wall 212 of the inner casing 109, that are receivable in openings formed in the first ends 194, 194′ of the catch portions 115, 115′ to pivotally mount the first and second catch portions 115, 115′ in the inner casing 109. It is appreciated that the shape and the configuration of the lock catch 114, as well as the shape, the configuration and the number of the catch portions 115, 115′ can vary from the embodiment shown.
The locking assembly 110 further comprises first and second biasing members 117, 117′, such as springs, that are arranged in the interior volume 105 of the inner casing 109 to cooperate respectively with the first and second catch portions 115, 115′ and that are configured to exert a biasing force against the first and second catch portions 115, 115′ to bias the first and second catch portions 115, 115′ into the engaged configuration. The first and second biasing members 117, 117′ are thus configured to bias the first and second catch portions 115, 115′ towards the unlocking component 120, and more particularly towards the inner end 134 (or unlocking end 134) of the unlocking body 130, in the embodiment shown). In the embodiment shown, the first second biasing members 117, 117′ are formed integral with the first and second catch portions 115, 115′ and extend from the first and second ends 194, 194′ thereof. It could also be conceived a locking assembly 110 comprising first and second biasing members 117, 117′ that would be distinct from the first and second catch portions 115, 115′.
In the shown embodiment, the unlocking body 130 comprises a peripheral wall 137 extending between the actuation end 132 and the unlocking end 134 and having a tapered shape. The cross-section of the peripheral wall 137, considered in a plane substantially perpendicular to the unlocking axis X1, increases from the actuation end 132 towards the unlocking end 134.
The pushbutton 140 comprises a head 142, having a substantially circular shape; the head 142 has an inner face (or unlocking face) 143 and an outer face (or actuation face) 145. The pushbutton 140 further comprises a stem 144 extending substantially perpendicularly from the unlocking face 143 of the head 142, the stem 144 being dimensioned to be slidably received in the through opening 136 formed in the unlocking body 130. In the embodiment shown, as represented for instance in
The stem 144 extends longitudinally along an axis that corresponds substantially to the unlocking axis X1 of the unlocking body 130.
The pushbutton 140 and the unlocking body 130 are dimensioned so that the outer surface 133 of the outer end 132 (or actuation end 132) of the unlocking body 130 is partially covered by the head 142 of the pushbutton 140 in a manner such that an exposed portion 235 of the outer surface 133 of the actuation end 132 of the unlocking body 130 is substantially annular in shape. In other words, the outer surface 133 of the actuation end 132 of the unlocking body 130 includes a central portion 233 covered by the head 142 of the pushbutton 140 (i.e. facing the inner face 143 of the head 142), and the exposed portion 235 (
As shown in particular in
In the embodiment shown, the locking assembly 110 further comprises a locking hood 250 engageable with the locking assembly cover 150 (for instance via mounting arms 154 protruding from a lower surface of the locking assembly cover 150 receivable into mounting apertures 252 formed in the locking hood 250) to partially close the inner casing 109. It is appreciated that the shape and the configuration of the locking assembly cover 150 and the locking hood 250 can vary from the embodiment shown. It could also be conceived a locking assembly cover 150 that would be directly mountable to the inner casing 109.
The locking assembly 110 further comprises a function switch 170 that is translatable along a translation axis X3. In the shown embodiment, the translation axis X3 is substantially perpendicular to the unlocking axis X1. In the embodiment shown, the function switch 170 is slidable along an outer face 209 of the bottom wall 212 of the inner casing 109 (for instance between guiding rails 211 protruding from the outer face 209 of the inner casing 109, as represented in
The function switch 170 comprises a pushbutton abutment 172 and is translatable along the translation axis X3 between a first configuration (or pushbutton-blocking configuration) in which the function switch 170 prevents the pushbutton 140 from being translated since the inner end 146 of the stem 144 abuts against the pushbutton abutment 172 of the function switch 170, and a second configuration (or pushbutton-displacement configuration) in which the pushbutton 140 is translatable in a direction substantially parallel to the unlocking axis X1, i.e. the pushbutton abutment 172 of the function switch 170 does not abut against the inner end 146 of the stem 144 and thus does not obstruct the translation of the pushbutton 140 along the direction substantially parallel to the unlocking axis X1.
It is to be noted that, due to the function switch 170 being located in the housing 102 of the dispenser 100, the function switch 170 is prevented from being displaced from the first configuration (or pushbutton-blocking configuration) to the second configuration (or pushbutton-displacement configuration) when the cover 108 and the base part 106 are configured in the closed configuration, i.e. access to the function switch 170 is prevented when the housing 102 of the dispenser 100 is configured in the closed configuration. Therefore, the function switch 170 can only be displaced from the first configuration to the second configuration (and vice-versa) (i.e. the locking assembly 110 can only change from the key-opening configuration to the pushbutton-opening configuration) when the base part 106 and the cover 108 of the housing 102 of the dispenser 100 are configured in the open configuration for the function switch 170 to be accessible. As will be described in more details later, the key 180 is required to unlock the housing 102 and configure same into the open configuration to provide access to the function switch 170, and then to allow changing the locking assembly 110 from the key-opening configuration to the pushbutton-opening configuration.
Moreover, the pushbutton abutment 172 of the function switch 170 is shaped and dimensioned to at least partially circumvent the unlocking end 134 (or inner end 134) of the unlocking body 130. In the embodiment shown, a longitudinal slot 135 (as represented in
It is appreciated that the shape, the configuration, and the location of the function switch 170 with regards to the dispenser 100 can vary from the embodiment shown. For instance, the function switch 170 could be slidably mounted within the interior volume 105 of the inner casing 109.
Locking Assembly Operation
The different configurations of the first embodiment of the locking assembly 110 according to the present disclosure will now be described with reference to
When in the key-opening configuration, the function switch 170 is configured in the first configuration in which the function switch 170 prevents the pushbutton 140 from being displaced, i.e. translated towards the dispensing chamber 104. When in the key-opening configuration, the pushbutton abutment 172 of the function switch 170 prevents the pushbutton 140 from being translated in the interior volume 105 of the inner casing 109 along the unlocking axis X1.
More precisely, pressure is applied on the exposed portion 235 of the outer surface 133 of the unlocking body 130, i.e. the portion of the outer surface 133 that is not covered by the head 142 of the pushbutton 140. To this end, the above-mentioned key 180 can be used.
As shown in
Going back to
Due to the translation of the unlocking body 130 along the unlocking axis X1, the peripheral wall 137 of the unlocking body 130 further contacts/engages the first and second catch portions 115, 115′. Since the unlocking body 130 has a tapered shape, as the unlocking body 130 is further translated along the unlocking axis X1, the first and second catch portions 115, 115′ are pivoted respectively about the first and second pivot axes X2, X2′ towards the disengaged configuration, i.e. away from one another. The unlocking body 130 applies a force against the biasing force exerted by the first and second biasing members 117, 117′ onto the first and second catch portions 115, 115′ to pivot them into the disengaged configuration.
When the first and second catch portions 115, 115′ are in the disengaged configuration, the lock catch 114 is disengaged from the catch-engaging portion 112. Therefore, the cover 108 and the base 106 can be moved relatively to each other into the open configuration.
In the pushbutton-opening configuration, the function switch 170 is configured in the second configuration (or pushbutton-displacement configuration) wherein the pushbutton 140 is displaceable/translatable along a direction substantially parallel to the unlocking axis X1 (i.e. wherein the pushbutton 140 does not abut against the pushbutton abutment 172 of the function switch 170).
It is to be noted that no key is required to exert a pressure on the unlocking component 120 when the locking assembly 110 is configured in the pushbutton-opening configuration: the user can use his/her finger, or any adapted tool having a portion dimensioned to be introduced in the central opening 152 formed in the locking assembly cover 150.
When a pressure is exerted on the unlocking component 120, the locking assembly 110 being in the pushbutton-opening configuration, the unlocking body 130 and the pushbutton 140 are translated together along the unlocking axis X1. In a way similar to the above disclosed operation of the unlocking component 120 when the locking assembly 110 is configured in the key-opening configuration, the peripheral wall 137 of the unlocking body 130 then contacts/engages the first and second catch portions 115, 115′ and pushes them apart. More particularly, the first and second catch portions 115, 115′ are pivoted respectively about the first and second pivot axes X2, X2′ into the disengaged configuration and against the biasing force exerted by the first and second springs 117, 117′.
As mentioned above, when the first and second catch portions 115, 115′ are in the disengaged configuration, the lock catch 114 is disengaged from the catch-engaging portion 112. Therefore, the cover 108 and the base part 106 can be moved relatively to each other into the open configuration.
A second embodiment of the locking assembly 110 is shown in
As in the first embodiment, the locking assembly 110 comprises an unlocking component 120 having an unlocking body 130 translatable to configure the locking assembly 110 into the unlocked configuration and a pushbutton 140 partially contained in the unlocking body 130. The pushbutton 140 is prevented from translation along a direction substantially parallel to the unlocking axis X1 when the locking assembly 110 is in the key-opening configuration.
The second embodiment of the locking assembly 110 mainly differentiates from the first embodiment in the shape of the unlocking body 130. As shown for instance in
Apart from the shape of the unlocking 130, the second embodiment of the locking assembly 110 also differentiates from the first embodiment by the cooperation between the lock catch 114 and the locking casing 109 (or inner casing 109). In the second embodiment, as represented in
It is to be noted that the locking assembly 110 is not limited to the disclosed embodiments. In particular, the shape, the configuration and the arrangement of the different components of the unlocking component 120 and/or any component of the locking assembly is not limited to the above described first and second embodiments.
For instance, the different components of the locking assembly 110 can be modified so that the peripheral groove 160 at least partially delimited by the exposed portion 235 of the actuation end 132 of the unlocking body 130, presents a different shape.
It will be appreciated that the methods described herein may be performed in the described order, or in any suitable order.
Several alternative embodiments and examples have been described and illustrated herein. The embodiments of the invention described above are intended to be exemplary only. A person of ordinary skill in the art would appreciate the features of the individual embodiments, and the possible combinations and variations of the components. A person of ordinary skill in the art would further appreciate that any of the embodiments could be provided in any combination with the other embodiments disclosed herein. It is understood that the invention may be embodied in other specific forms without departing from the central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein. Accordingly, while the specific embodiments have been illustrated and described, numerous modifications come to mind. The scope of the invention is therefore intended to be limited solely by the scope of the appended claims.
The present application claims priority from U.S. provisional patent application No. 62/663,330, filed on Apr. 27, 2018, and entitled “LOCKING ASSEMBLY FOR A DISPENSER AND DISPENSER”, the disclosure of which being hereby incorporated by reference in its entirety.
