This application derives priority from New Zealand patent application number 777205 filed on Jun. 15, 2021 with WIPO DAS code 3BF0, the contents of which are incorporated herein by reference.
Broadly described herein is reconfigurable buggy. More specifically, a system and method are described to releasably link two buggy's together in a series configuration.
Existing strollers are often manufactured to convey one child. Single buggy's to convey two children may be side by side, this configuration being a wide configuration. So-called ‘inline’ configurations also exist where the child seats are on a single buggy, one seat behind the other seat.
One option to link an accessory to a buggy is described in U.S. Pat. No. 10,683,025. The accessory is described in this patent as being a chassis with wheels. The chassis cannot be used to convey a child on it's own and requires connection to a buggy via a specific connection mechanism to be used. The connection mechanism is described as having extending male members mating with female openings in the frame legs sides. When the accessory is connected to the buggy, a pivot axis is defined by the connection point that allows the accessory to rotate about the connection in a vertical plane.
An alternative linking mechanism is described in U.S. Pat. No. 8,657,303. In this case, the linking mechanism is used to link a scooter to the rear of a buggy via a linking mechanism using interlinking male pins and female openings that cooperate about a vertical plane to releasably connect the scooter and buggy.
A variation to the above is described in US 2020/0223469. In this patent publication, the accessory is a seat on a chassis and with two rear wheels. The accessory cannot be used alone and in fact folds up when not in use for ease of carriage. The accessory is connected to a buggy via the connection mechanism described in U.S. Pat. No. 10,683,025. Critical to the design is a transfer of braking so that, when the brakes are applied by a user to the accessory, the accessory communicates this to the buggy and the buggy brakes are then actuated. The accessory itself has no braking capability.
A problem in the art relates to how two separate buggy's may be used separately or releasably linked together in a series configuration. Existing double buggy's cannot be detached into two single buggy's. The solutions of U.S. Pat. No. 10,683,025 and US 2020/0223469 are not two separate buggies' linked together and have a lower value to the purchaser since the accessory can only be used when in the use configuration. The accessory cannot be used alone meaning an extra item and expense to the purchaser.
A common scenario for a growing family is that a consumer may purchase a first buggy for their first child and then, when a second child arrives, the parents are faced with decision on whether to purchase double buggy's, two separate buggy's or an accessory. Sometimes this might mean purchase of a further first buggy as well. It may be useful to be able link two separate buggy's together but also use either buggy separately on their on or at least provide the public with a choice.
Further aspects and advantages of the reconfigurable buggy will become apparent from the ensuing description that is given by way of example only.
Described herein are reconfigurable buggy's, more specifically the ability to releasably connect two individual buggy's to form one in-line tandem buggy. Methods of coupling and uncoupling are also described along with a connection detail kit that a consumer may look to purchase separately to a buggy or buggy's.
In a first aspect, there is provided an in-line tandem buggy configured for carriage of two or more child seats, the in-line tandem buggy comprising:
In a second aspect, there is provided a method of coupling a first buggy and a second buggy to form an in-line tandem buggy by:
In a third aspect, there is provided a method of un-coupling an in-line tandem buggy to a first buggy configuration and a second buggy configuration by:
In a fourth aspect, there is provided a kit configured to couple two buggy's together to form an in-line tandem buggy, the kit comprising:
An advantage of the above may include versatility to the consumer allowing them to purchase individual buggy's and separately a connection detail. This means the consumer may use the two buggy's individually or combined together and operable by one person.
Further aspects of the reconfigurable buggy will become apparent from the following description that is given by way of example only and with reference to the accompanying drawings in which:
As noted above, described herein are reconfigurable buggy's, more specifically the ability to releasably connect two individual buggy's to form one in-line tandem buggy. Methods of coupling and uncoupling are also described along with a connection detail kit that a consumer may look to purchase separately to a buggy or buggy's.
For the purposes of this specification, the term ‘about’ or ‘approximately’ and grammatical variations thereof mean a quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length.
The term ‘substantially’ or grammatical variations thereof refers to at least about 50%, for example 75%, 85%, 95% or 98%.
The term ‘comprise’ and grammatical variations thereof shall have an inclusive meaning—i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components or elements.
For the purposes of this specification, the terms ‘child buggy’, ‘buggy’, ‘perambulator’ and grammatical variations thereof collectively and interchangeably refer to child carrying and supporting products used to transport one or more children. The child/children may be babies or toddlers.
In a first aspect, there is provided an in-line tandem buggy configured for carriage of two or more child seats, the in-line tandem buggy comprising:
The first and second buggy's, when combined, may form a train, one buggy ahead of the other buggy to form the in-line tandem buggy.
The first and second buggy's, when combined, or the in-line tandem buggy may move or moves as one unit. Once coupled to an in-line tandem buggy, the first and second buggy's cannot move independently and a force applied to the rear of the in-line tandem buggy, e.g. on the second buggy handle, causes transfer of the force to the first buggy in the in-line tandem buggy so the in-line tandem buggy moves as one item. For example, if a turning force is applied to the rear of the in-line tandem buggy, the whole in-line tandem buggy turns. Similarly, if a forwards of backwards motion force is applied to a part of the in-line tandem buggy, the whole in-line tandem buggy moves as one in response to the forwards or rearwards motion force. A force transferred from one part of the in-line tandem buggy may be directly transferred across the in-line tandem buggy—that is, there is no indirect or variable linkage between the first and second buggy's once coupled.
The first or second buggy may comprise one or two child conveying seats. When the first or second buggy individually comprises two seats, the seats may be side by side or one behind the other (in-line).
The first and second buggy's may be configured for use on their own in an un-linked manner. They may be purchased and used as individual buggy's.
The connection detail may couple a rear of the first buggy to a front of the second buggy.
The connection detail may comprise a plate with connection members at either end of the plate and, wherein the connection members on one end of the plate couple to the first buggy and, connection members on an opposing end of the plate couple to the second buggy.
Once coupled, the in-line tandem buggy may be braked by use of brakes on the second buggy. The brake mechanism of the second or rear buggy in the in-line tandem buggy configuration may be disconnected from the second buggy. As a result, braking of the in-line tandem buggy occurs using the brake mechanism on the first or front buggy. This may be a park or foot brake located about the rear base of the first buggy. In this embodiment, the park brake is accessed from the side of the in-line tandem buggy. There is no link between a brake or brakes on the first and second buggy's when in an in-line tandem buggy configuration. That is, actuation of the brake(s) of the rear or second buggy in the in-line tandem buggy configuration does not cause any braking of the first buggy or first buggy brake(s).
In one embodiment, the connection detail may comprise:
Optionally, in the connection detail above, the further plate and the second buggy connection members may engage together to retain the second buggy connection member(s) within the aperture(s).
The plate may engage one or more apertures on the second buggy linking members.
In one embodiment the aperture may be a continuous channel around the circumference of one or more rod shaped second buggy connection members.
In one embodiment, the further plate may be movable in a horizontal plane relative to the second end of the base section and plate cover section from a second buggy connection member engaged position to a non-engaged position.
Movement of the further plate relative to the base section may be urged via an actuator.
In one specific embodiment, two actuators, optionally being push buttons, may be used, located on either side of the further plate.
In one embodiment the linking mechanism may include a bias means that biases the further plate to an engaged position that retains the second buggy connection member or members in the aperture or apertures of the base section.
The bias means may be a spring.
Other variations in connection detail may be employed such as those outlined in U.S. Pat. No. 8,657,303 incorporated herein by reference.
Optionally, the front strut of the second buggy may be removed and replaced with leg extensions and wheels. Increasing the height of the front of the second buggy when in the in-line tandem buggy configuration may be useful to level the second buggy relative to the first buggy since the front of the second buggy when fitted to the rear of the first buggy may also be lifted slightly relative to the original second buggy height above the ground.
In a second aspect, there is provided a method of coupling a first buggy and a second buggy to form an in-line tandem buggy by:
In a third aspect, there is provided a method of un-coupling an in-line tandem buggy to a first buggy configuration and a second buggy configuration by:
In a fourth aspect, there is provided a kit configured to couple two buggy's together to form an in-line tandem buggy, the kit comprising:
An advantage of the above may include versatility to the consumer allowing them to purchase individual buggy's and separately a connection detail. This means the consumer may use the two buggy's individually or combined together and operable by one person.
The embodiments described above may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more said parts, elements or features.
Further, where specific integers are mentioned herein which have known equivalents in the art to which the embodiments relate, such known equivalents are deemed to be incorporated herein as if individually set forth.
The above described reconfigurable buggy is now described by reference to specific examples.
An embodiment of the in-line tandem buggy and separate buggy's and connection detail is now described with reference to
As shown in the Figures, once coupled, the in-line tandem buggy 1 may be braked by use of the first buggy 3 brake(s). The brake mechanism of the second buggy 4 in the in-line tandem buggy 1 configuration is disconnected from the second buggy 4 (the rear strut). As a result, braking of the in-line tandem buggy 1 occurs using the brake mechanism on the first buggy 3. In the Figures, this is a foot activated brake located about the rear base of the first buggy 3 and the park brake is accessed from the side of the in-line tandem buggy 1. There is no link between a brake or brakes on the first 3 and second 4 buggy's when in an in-line tandem buggy 1 configuration.
Aspects of the reconfigurable buggy have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope of the claims herein.
