Title: Locker with an urging module for opening the door

TECHNICAL FIELD

The various aspects and examples thereof relate to a locker for storing goods, for example personal belongings at a venue and to an urging module for urging a door of such locker to an opened position.

BACKGROUND

Lockers are provided at venues at which people are required or may want to store their belongings at a safe place, for example at a swimming pool, a fitness centre, a concert hall or other. Generally, such lockers are provided with a mechanical lock that is operable with a key. If the locker is used, the key is removed; if the key is in the keyhole of the applicable locker, the locker is free to use.

SUMMARY

Mechanical locks of lockers are being replaced with retrofit electromechanical locks. The actual cabinets are with the such retrofit locks, as the cabinets still function. However, electromechanical locks provide several advantages, such as - optional - remote control and remote and sensing tracking of use of the locks. Such electromechanical locks are oftentimes provides with a keypad.

A disadvantage of such locks that from the outside, it is not visible whether or not a locker is in use: with no key used, the detection whether or not a locker is in use by means of absence or presence of a key is not possible anymore. Therefore, other means are required. A light source may be provided, turning green when not in use and red when in use - or the other way around - is possible. Yet, this consumes energy and is not always preferred when locks run on batteries.

A first aspect provides an urging module for urging a door of a locker to an opened position. The urging module comprises a module body comprising an interface surface arranged to engage with an inner surface of at least one of a door of a locker and a fixed wall of a locker and a resilient spring member protruding from the module body in a direction having a component parallel to the interface surface.

The urging module may be placed on an inner wall of the door in a way that it abuts a part of the cabinet of the locker, like an inner wall or an edge thereof, when the door is closed, such that the spring member is deformed. Due to its resilient nature, the spring member will exert an urging force on the cabinet while the door is kept closed, urging the door towards an open position. The urging module may also be place on a part of the cabinet of the locker, for example an inner wall, in a way that the spring member abuts the door when the door is closed, such that the spring member is deformed when the door is in a closed state.

When the door is locked, for example by means of a bolt or an electromagnet, the spring member will remain deformed, between the door and a part of the cabinet. When the door is unlocked, the door is able to move freely relative to the stationary cabinet and will be able to swing or slide open. And urged by the spring member, the door will move open.

Furthermore, the door will not be able to close fully due to the urging force of the spring member.

This feature will allow a user to discriminate an open and therefore generally not occupied locker from a closed and therefore generally occupied locker, even if there is no visual indicator at the front, like presence or absence of a key or a light of a particular colour. Furthermore, the urging module may be incorporated or integrated in a retrofit electromechanical lock. In the first place, this makes manufacturing more efficient. Second, this means that no additional work is required for installing the urging module together with retrofit electromechanical lock.

In an example, the spring member protrudes from the module body at a distance from the interface surface. This allows the spring member to be installed at a distance from a surface. This allows in a first example, wherein the urging member is attached to a door, for the spring member to abut the cabinet before the door abuts the cabinet. In turn, this results, when the door is fully closed, in a relatively large deformation of the spring member and a considerable urging force. In a second example, wherein the urging member is connected to the cabinet, for example to an inner wall from which the spring member protrudes outside of the cabinet, allows for the spring member to abut the door before the door abuts the cabinet. This has the same effect as in the first example.

In again another example, the spring member protrudes from the module body at an offset distance from the interface surface, determined in a direction substantially perpendicular to the interface surface. This provides more effective advantages of the examples directly above.

In a further example, the offset distance is smaller than a spring length of the spring member at which the spring protrudes from the module body. Depending on how the urging member 1s assembled, this example may allow for multiple deformations, for example bending at two locations. This provides additional urging force.

In another example, the spring member protrudes in a direction substantially parallel to the interface surface. In this example, deformation of the spring member includes bending of the spring member. Whereas other types of deformation may be envisaged - stretching, compression, twisting - bending may result in a proper urging force. In one particular example, closing of the door may result in a combination of two or more types of deformation. It is noted, that the resilient spring element may have different shapes; flat and elongated may be better for bending. Yet, the resilient spring element may also be a broader protrusion, hollow or massive, that is more suitable for compressive deformation, whereas it is still suitable for providing an appropriate urging force.

In yet a further example, the spring member comprises a substantially flat spring body, having a spring thickness substantially perpendicular to the interface surface that is at least five times smaller than a spring length at which the spring member protrudes from the module body. Such flat spring member is simple to manufacture and use for assembly. Furthermore, it is suitable for different types of deformation to generate the urging force.

In again a further example, the spring member predominantly comprises at least one elastomer. Such material is generally not susceptible to corrosion, relatively cheap and relatively simple to manufacture and to handle.

In yet another example, the interface surface has a substantially planar surface. Such shape allows for deformation without too much risk for wear. Second, it may allow for direct assembly to a wall of the cabinet or an inner surface of the door. As such, the body of the urging module and the spring element may be manufactured in one monolithic element.

A second aspect provides a locking device comprises a lock for lockingly engaging with a wall of the locker and the urging module according to the first aspect or an example thereof. This aspect provides a ready to use and install locking device in an existing locker - for example in the door - without having to install a separate urging member.

In an example of the first aspect, the interface surface of the urging module is integrated in a device interface surface that is arranged to engage with the inner surface of the door of the locker. The interface surfaces may as such integrated form one contiguous surface, which may in a specific example be part of a single housing, serving as a body for holding the spring member and for holding the lock.

In another example, the lock comprises a bolt arranged to translate in a direction substantially parallel to the device interface surface.

Such locks provide effective locking of a door, with the bolt engaging with a hole in an inner surface of a wall of a stationary part of a locker. 5 A further example further comprises an electromagnet arranged to engage with at least one of a wall of the locker and a ferromagnetic component fixedly attached to the locker. Such example does not use mechanical parts, which means less wear. Yet, it may require a continuously running current.

Again another example further comprises a human interaction input module and an electronic circuit, wherein the electronic circuit is arranged to operate the lock based on information received via the human interaction input module. This enables or enhance control of the lock, directly by a human being.

A third aspect provides a locker comprising a cabinet space and a door connected to the cabinet space by means of at least one hinge provided at a first edge of the door, the locker comprising the urging module according to any according to the first aspect, wherein the urging module is arranged such that when the door closes an opening of the cabinet space, the urging module urges the door to an open position. This provides a locker with advantages discussed in conjunction with the first aspect.

In an example of the third aspect, when the door is closed, an inner surface of the wall of the locker and a second edge of the door, the second edge being different than the first edge, are spaced away by a spacing distance, wherein the spring member has a thickness equal to or smaller than the spacing distance. In such closed state, at least part of the door abuts at least part of a wall of the cabinet - at at least one of top, bottom and side. In this example, the door does not abut the cabinet at each point along the opening of the cabinet: this allows the spring member to be deformed between door and cabinet, without being squeezed. This may prolong lifetime of the spring member.

In another example, the second edge is opposite to the first edge.

Whereas the spring member does not have to be provided at an edge of the door opposite to where the door 1s connected to the cabinet, such example may provide advantages. One is that a locking device, in which the urging device may be incorporated, is generally provided at such second edge opposite to the first edge.

In yet a further example, a door area of the door is larger than an opening area of the opening of the cabinet space and wherein the urging module is place at the inner wall of the door at a distance from an adjacent edge of the door. This example allows for the module body to fit into the opening area, whereas the spring would be provided between the inner surface of the door and an edge of a wall of the cabinet adjacent to the door where the urging member is provided. This example is particularly effective if the spring member protrudes from the module body at a distance from the inner surface of the door, determined in a line substantially perpendicular from the inner surface of the door.

In again another example, the urging module is connected to an inner surface of the door at or near a second edge of the door, the second edge being different than the first edge.

In a further example, the urging module is connected to an inner surface of a wall of the cabinet space, at or near an opening of the cabinet space, such that when the door is closed, the urging module is provided at or near a second edge of the door, the second edge being different than the first edge, such that when the door is closed, the resilient spring member urges the door to an opened position. This example may be advantageous for lockers that have already been provided with a retrofit lock, but not yet with the urging members. It is noted that urging members for doors in general are known, but these are generally provided with a helical spring around hinges or comprise push rods urged by helical springs. Such constructions are far more complex than the urging member of the first aspect and may be more complex to install.

Yet another example further comprises the locking device of the second aspect.

DETAILED DESCRIPTION

Figure 1 shows a locker 100. The locker 100 may be placed at venues at which people are required or may want to store their belongings at a safe place, for example at a swimming pool, a fitness centre, a concert hall or other. The locker 100 comprises a cabinet 110 having a first sidewall 114, a second sidewall 116, a top wall 118 and a bottom wall 112. The locker cabinet 110 thus has an opening defined by the walls; the opening is in this example provided in a plane defined by edges of the four walls discussed above.

To the second sidewall 116, a door 120 is connected by means of a first hinge 122 and a second hinge 124. In another example, more or less hinges are provided. In again another example, the door 120 is connected to one of the first sidewall 114, the bottom wall 112, or the top wall 118. In yet another example, the door 120 is a sliding door.

The door 120 is provided with a lock 140 as an example of a locking device. The lock 140 comprises a lock body having a lock casing 142.

Within the lock casing 142, a bolt 144 is provided. In this example, the bolt 144 1s provided in the lock casing in a way that allows the bolt 144 to move in a translating fashion. In another example, the bolt 144 may be provided in a way that allows a rotating movement. The bolt 144 is arranged to engage with a hole 148 in the first sidewall 144 to lock the door 120 of the locker 100.

Movement of the bolt 144 may be controlled by means of an electronic circuit 152. The electronic circuit 152 is in this example connected to a keypad 154 as a human interaction input module for receiving instructions for a human to control the electronic circuit 152. The electronic circuit 152 may comprise an electromechanical actuator, like an electromotor or a solenoid with a ferromagnetic core arranged to translate within the solenoid, to control operation and therewith movement of the bolt 144. In another example, locking is provided by means of an electromagnet,

that provides a strong attraction force between the door 120 and the locker cabinet 110, either attracting to one or more walls or a separate bracket connected thereto. The lock casing 142 may comprise a battery for powering the electronic circuit 152.

From the lock casing 142 protrudes a resilient flap 146 as a spring member. The resilient flap 146 is in this example substantially planar. For the resilient flap 146, the lock casing 142 serves as a body for holding the resilient flap 146. As such, the ensemble of the lock casing 142 and the resilient flap serves as an example of an urging module.

In this example, the resilient flap predominantly comprises an elastomer, like natural or synthetic rubber. Predominantly may in this context be understood as at least 80%, at least 90% or even at least 95%. In another example, the resilient flap comprises an organic polymer or a metal, like steel or a memory metal. Other materials having similar properties may be used as well, alone or in combination with the rubber or metal.

The resilient flap 146 is in this example relatively thin; the resilient flap 146 protrudes in this example from the lock casing at a length at least five time more than the thickness of the resilient flap 146.

The lock casing 142 is with one side connected to the door 120, with a contact surface of the lock casing 142 engaged with an inner surface of the door 120. The contact surface of the lock casing 142 in this example also serves as a contact surface for a body for connecting the resilient flap to the inner wall of the door 120.

A connection between the lock casing 142 and the inner surface of the door may be enhanced by means of using an adhesive, like glue, mechanical fastening means like screws, nails, brackets, other, or a combination of two or more thereof.

The functioning of this urging module is explained below in conjunction with Figure 2 A and Figure 2 B. Figure 2 A shows a stop view of the locker 100 shown by Figure 1. As shown by Figure 2 A, the door 120 is in an open position. In this position, the resilient flap 146 protrudes from the lock casing 142 substantially parallel to the contact surface of the lock casing 142 as well as the inner surface of the door 120. Within this context, ‘substantially’ is to be understood as having a deviation of 10° towards each side.

In another example, the resilient flap may deviate by more than 10° from parallel to one or both of the planes of the inner surface of the door 120 and the contact surface of the lock casing 142. In such example, the resilient flap 146 protrudes from the lock casing 142 in a direction having a component parallel to contact surface of the lock casing 142 as well as the inner surface of the door 120. It is noted that in this example, the contact surface of the lock casing 142 and the inner surface of the door 120 may be parallel as well as planar. These are options in other examples, one or both surfaces are not planar.

Figure 2 A shows the resilient flap 146 being provided at a distance from the contact surface of the lock casing 142 and hence, also from the inner surface of the door 142. The distance between a location at which the resilient flap 146 protrudes from the lock casing 142 is in this example a multitude of the thickness of the resilient flap 146. In another example, the resilient flap 146 is provided in direct contact with the inner surface of the door 120, with the resilient flap 146 providing an interface surface arranged to engage with the inner surface of the door 120.

Figure 2 B shows the door 120 in a closed position, closing the opening of the locker cabinet 110. With the resilient flap 146 being provided at a distance from the inner surface of the door 120, the resilient flap 164 is bent between an inner surface of the first sidewall 114 and the lock casing 142. Furthermore, in this example, due to the length at which the resilient flap 146 protrudes from the lock casing 142 serving as a holding body for the resilient flap 146, the resilient flap 146 is, as an option, bent a second time and clamped between an edge of the first sidewall 114 and the inner surface of the door 120.

By virtue of the bending of the resilient flap 146, stress occurs within the resilient flap 146. By virtue of that stress, the resilient flap 146 urges the door 120 to an open position, as an urging member. When the bolt 144 engages with the hole 148, the door 120 is locked and will not open, despite the urging force exerted by the resilient flap 146. When the bolt 144 is withdrawn from the hole 148, the door 120 is not blocked from moving to an open position and the resilient flap 146 will push the door 120 from the closed position shows by Figure 2 B to the open position shown by Figure 2

A.

In another example, the resilient flap 146 provided in the lock casing 142 may additionally or alternatively engage with the top wall 118 or the bottom wall 112. In another example, multiple resilient flaps may be provided, each interacting with another sidewall or the same sidewall.

Figure 3 shows a locker 100. The locker 100 shown by Figure 3 differs from the locker 100 shown by Figure 1 in the sense that with the locker 100 shown by Figure 3, the door 120 closes inside the opening of the locker cabinet 110, rather than that it covers the opening of the locker cabinet 110. Apart therefrom, parts of the locker 100 of the example shown by Figure 3 are substantially the same as those of the example shown by

Figure 1 and referenced by the same reference signs.

A difference between both examples is further elucidated by

Figure 4 A and Figure 4 B. Figure 4 A shows the door 120 in an open position and Figure 4 b shows the door 120 in a closed position. With the door 120 closing within the plane of the opening of the locker cabinet 110, the resilient flap 146 is bent once, between an edge of the door 120 that is adjacent to the first sidewall 114 and the inner surfaced of the first sidewall 114. As discussed above, the bending of the resilient flap 146 results in the resilient flap 146 exerting a force on the inner surface of the first sidewall,

resulting in the door 120 being urged to an open position when the bolt 144 is not engaging with the hole 148.

Figure 5 shows another example. Rather than being incorporated in the lock casing 142, the resilient flap is connected to the inner surface of the first sidewall 114. Apart therefrom, parts of the locker 100 of the example shown by Figure 5 are substantially the same as those of the example shown by Figure 1 and referenced by the same reference signs. The resilient flap 146 may in the example depicted by Figure 5 be affixed to the inner surface of the first sidewall 114.

The resilient flap 146 is in this example directly affixed to the inner surface of the first sidewall 114, thus providing its own connecting body.

In another example, an additional body structure is provided in which the resilient flap 146 is incorporated and which body is connected to the inner surface of the first sidewall 114. The connecting of the resilient flap 146 and, optionally, a separate body for holding the resilient flap, may be connected to the inner surface of the second sidewall 114 as discussed above. The connecting body and the resilient flap 146 may be manufactured from one and the same material, as a monolithic element. Additionally or alternatively, the connecting body may comprise another material. The other material may be co-moulded with the material of the resilient flap 146 and/or provided as a completely separate component, later joined with the resilient flap 146.

Figure 6 A shows the door 120 in an open position, with the resilient flap 146 protruding beyond an edge of the first inner wall 114, substantially parallel to the inner surface of the inner wall 114. Figure 6 B shows the door 120 in a closed position, with the resilient flap 146 bent between an edge of the first sidewall 114 and the inner surface of the door 120. As discussed above, in this position, the resilient flap 146 exerts an urging force on the door 120, urging the door 120 to an open position. It is noted that the resilient flap 146 may additionally or alternatively be connected to the top wall 118 or the bottom wall 112. If the resilient flap 146 is connected to the top wall 118 or the bottom wall 112, the resilient flap 146 is in such example connected to the applicable wall close to the first sidewall 114. Close may in this context be understood as at 30% or less of the length of the applicable wall, determined from the first sidewall 114. In alternative examples close may be determined as at 20% or less, at 15% or less, at 10% or less, or at 5% or less from the first sidewall 114.
