The invention relates to locking systems. More precisely, the invention pertains to an electronic lock for securing a movable item to a structure and an associated method.
Securing a moveable item to a structure is of great interest for various applications. For instance, it may be desirable to secure a vehicle to a fixed structure. This may be particularly advantageous in applications where the vehicle is to be rented for a given amount of time.
More specifically, there has been in recent years a rise in the popularity of automated rental systems for vehicles such as bicycles for example. Such a system generally comprises an automated rental station from which a user may rent a bicycle for a given amount of time.
In such a system, a bicycle to be rented is generally removably secured to a bicycle rack by means of a locking mechanism. A user may selectively unsecure and secure again the bicycle from the bicycle rack in certain circumstances, for instance after paying a given fee and/or providing a personal identification code.
Such rental systems generally comprise a plurality of rental stations located in different public locations, making them likely targets of acts of vandalism from malevolent individuals. Their robustness is thus an important element of a successful rental system.
For example, U.S. Pat. No. 5,917,407, granted to Squire, discloses an automated bicycle renting station wherein the bicycle rack comprises a locking mechanism having a hook or latch member. This hook or latch member is designed to selectively pivot around an axle to engage a rod or a keeper mounted on the bicycle to be secured, thereby effectively securing the bicycle to the renting station.
Such a station may be subject to vandalism. Indeed, a malicious person may tug at the bicycle engaged in the renting station, using the latch as a lever and the axle as a pivot point to bend the latch out of shape or damage the keeper and free the bicycle from the renting station without paying the given fee.
Other locking systems for bicycles have also been proposed in the art. However, such systems are still prone to property damage and theft of bicycles and may thus cause great financial harm to operators of such bicycle renting systems.
Moreover, in some bicycle rental systems, unsecuring a bicycle from a bicycle rental station involves lifting the bicycle or otherwise manipulating the bicycle such that a great physical effort is required from a user of the bicycle rental system. This activity is inconvenient for the user and may lead to injuries.
Furthermore, in some bicycle rental systems, the task of guiding the bicycle towards the bicycle rack for the purpose of securing the bicycle to the bicycle rack may be arduous and inconvenient for a user.

Now referring to
It will be appreciated that any other holding means allowing to temporarily retain the male connector 108 into the female connector 106 may be considered.
In one embodiment, this above described configuration further enables a movable item to be temporarily attached to a structure in a “reduced load” design. For instance, according to one configuration, the movable item may be engaged in the structure in a lockable position wherein the movable item does not rest on a lower surface. In such a configuration, the movable item may be temporarily retained in the lockable position using the holding means until the movable item is secured to the structure.
Now referring back to
More specifically, in one embodiment, the position detecting means may be adapted for detecting a positioning of the locking finger 508 in the finger channel 515.
According to one configuration, the position detecting means may comprise a contact detector (not shown) operatively mounted to the back wall 513 proximate the finger channel 515. The position detecting means may be activated when the front tapered portion 503 of the male connector 108 is moved forwardly into the recess 511 of the female connector 106 and the locking finger contacts the contact detector when engaging the finger channel 515.
In an alternative embodiment, the position detecting means may comprise a magnetic proximity detector operatively mounted into the back wall 513 proximate the finger channel 515. In such an embodiment, the locking finger 508 is provided with a magnet element (not shown) mounted therein. The position detecting means will be activated when the front tapered portion 503 of the male connector 108 is moved forwardly into the recess 511 of the female connector 106 and the magnetic proximity detector detects the presence of the magnet in the finger channel 515.
This configuration advantageously prevents the activation of the position detecting means when an object other than a corresponding male connector is engaged in the female connector.
In one embodiment, the detection of the male connector and the female connector in the lockable position is operatively coupled to an indicator for indicating the positioning of the male connector and the female connector in the lockable position to a user of the electronic lock. The indicator may be a visual indicator such as a LED or the like; alternatively. the indicator may be an audio indicator such as a speaker or the like.
In one embodiment, the position detecting means are operatively coupled to the electronic control means. In such an embodiment, the electronic control means are adapted for selectively actuating the actuator to move the movable locking finger 1000 from the unlocked position to the locked position upon detection of the positioning of the male connector 108 and the female connector 106 in the lockable position.
In another embodiment, the securing assembly 506 further comprises an identification tag (not shown) associated with the bicycle and an identification tag reader (not shown) for identifying the identification tag and the associated bicycle when the male connector and the female connector are engaged in the lockable position.
This configuration is of great advantage to enable a monitoring of the use of each of the bicycles. It may also be of great advantage in another application wherein a large number of items are temporarily stored and retrieved at a later time, for instance for identifying vehicles secured to racks in a warehouse.
In a further embodiment, the electronic control means are operatively coupled to both position detecting means and identifying means. In such an embodiment, the electronic control means are adapted for selectively actuating the actuator to move the movable locking member from the unlocked position to the locked position upon two conditions, a first condition being a detection of the positioning of the male connector and the female connector in the lockable position, a second condition being an identification of the associated bicycle.
In one embodiment, the identification tag comprises an RFID tag and the identification reader comprises an RFID reader mounted to the bicycle rack. This configuration is of great advantage since no electric wire between the tag and the reader is needed. The skilled addressee will appreciate that other arrangements may be considered. For example, a first and a second corresponding electric connector may be provided on each connector respectively. In this case, when the male connector engages the female connector, the two electric connectors engage together to obtain the identification information. The use of RFID technology is nevertheless preferred over the use of conventional electric connectors since it may help reduce breaking of the system.
It will be appreciated that this configuration is of great advantage in a bicycle rental system. Indeed, in such a system, the electronic lock detects the engagement of a rented bicycle being returned by a user into the bicycle rack and identifies the bicycle before securing the bicycle to the bicycle rack and charging a fee to the user according to given parameters.
