专利汇可以提供Collapsible supporting structure专利检索,专利查询,专利分析的服务。并且A collapsible supporting structure (eg the framework of a stroller) comprises a central mounting body (15) having rotatable disc (41). In the supporting arrangement (depicted) front leg (20) extends from the front surface of disc (41) and rear legs (18-19) extend rearwardly from the rear surface of disc (41). When folding the structure for transportation, rotation of disc (41) by approximately 180 ° brings all three legs (18-20) into an upwardly splayed position. Individual pivoting of legs (18-20) will then bring them into approximate coextension with arms (35-36). Disc (41) in use is locked against rotation, however twisting of a lock on top of body (15) allows pivotal convergence of arms (35-36). The movement of arms (35-36) presses on captive balls that in turn displace radial plungers so they lie within the periphery of disc (41), allowing its rotation.,下面是Collapsible supporting structure专利的具体信息内容。
The invention claimed is:
This invention relates to a collapsible supporting structure for supporting articles such as golf buggies, perambulators, strollers, push chairs, push carriers, and shopping trolleys. However it is not limited to such articles being wheeled structures but can be used for other collapsible structures which are needed to support a weight.
It is often necessary to support weights at various locations. Structures which fulfil the ability to support a load can be large heavy and cumbersome and are therefore not readily transportable to another location.
It is therefore an object of the invention to provide a structure which is able to support a load but is readily transportable.
In accordance with the invention there is provided a collapsible supporting structure having: a mounting body; a supporting frame mounted on the collapsible supporting structure for supporting a load; and at least one support leg connected to the mounting body by one or more connection means which enable the at least one support leg to move from a first supporting position in which the support leg extends in a first direction and allows loads to be supported on the collapsible supporting structure to a second transportable position in which the support leg extends in a second direction and allows ready transportability.
The collapsible supporting structure can include a plurality of support legs with each connected to and extending from the mounting body. The legs can be arranged having at least one support leg extending from a front portion of the mounting body to form front supporting legs and at least one support leg extending from a rear portion of the mounting body to form rear supporting legs.
The support legs of the collapsible supporting structure can have at least one wheel mounted on respective distal ends to the end connected to the mounting body.
The collapsible supporting structure can include upright arms extending in a direction on an opposing side to the extension of the at least one support leg. The upright arms allow for manoeuvrability of the collapsible supporting structure.
The connection means can include a rotation means which allows the at least one support leg to move from the first supporting position to the second transportable position by being rotated. The amount of rotation can be up to 180° such that the first supporting position is opposite the second transportable position. This can allow for substantial co-extension of the support legs and the upright arms which substantially decreases the volume of space used by the collapsible supporting structure in the collapsed transportable position relative to the useable supporting position.
The connection means can include pivoting means allowing for pivotal movement of the at least one support leg from a supporting position at an angle to the mounting body to a collapsible position adjacent the mounting body.
In one form the support legs are connected to the mounting body by connection means having rotation means and pivoting means such that the support legs can extend from the mounting body in a first splayed arrangement which forms the supporting position of a load to a second arrangement in which the support legs are pivoted inwards to substantially extend alongside the mounting body and rotated such that the support legs extend substantially alongside the upright arms.
The rotation means can include a disc mounted in the mounting body to allow rotation therein. An end of one or more support legs can be connected to the disc allowing rotation of the support leg. At least one of the support legs can be mounted on each side of the disc of the mounting body allowing for rotation of the attached support legs at the same time.
The rotation means can include a disc having two parts each with an outside surface and an interconnecting part. The rotation means is mounted in a hole in the mounting body with the two interconnecting parts engaging each other within the hole and the two outside surfaces being visible from the outside of the mounting body and able to have support legs attached thereon. The rotation means enabling simultaneous rotation of legs on either side of the mounting body. The rotation means can include locking means to selectively allow simultaneous rotation or separate rotation or independent rotation.
The pivoting means can include a hinge for connecting the support leg to the mounting body and preferably to the disc of the rotation means. The pivoting means can include a limiting shoulder piece fixed to the mounting body adjacent the hinged connection of the support leg and limiting the amount of pivot away of the support leg away from the mounting body. In this way the pivoting means can allow the support leg to pivot to the required splayed supporting position while allowing the support leg to move in towards the mounting body to a transportable position.
The supporting frame can be integral with the mounting body.
In another form the supporting frame is a collapsible structure which can be modified from a voluminous supporting structure to a minimised volume transportable structure. The supporting frame can be mounted on the upright arms of the collapsible structure.
Also in accordance with the invention there is provided a collapsible supporting structure in the form of a stroller or push chair, the structure including: a mounting body; elongated support legs pivotally and hingedly mounted on the mounting body and each having at least one wheel mounted on respective distal ends to the end connected to the mounting body; a supporting frame mounted on the mounting body for supporting a load; a plurality of support legs arranged with at least one support leg extending from a front portion of the mounting body to form front supporting legs and at least one support leg extending from a rear portion of the mounting body to form rear supporting legs; upright arms extending in a direction on an opposing side to the extension of the at least one support leg; the support legs connected to the mounting body by one or more connection means which enable the at least one support leg to move from a first supporting position in which the support leg extends in a first supporting direction and allows loads to be supported supporting frame on the collapsible supporting structure to a second transportable position in which the support leg extends in a second transportable direction and allows ready transportability.
The connection means can include a rotation means which allows the at least one support leg to move from the first supporting position to the second transportable position by being rotated. The amount of rotation can be up to 180° such that the first supporting position is opposite the second transportable position. This can allow for substantial co-extension of the support legs and the upright arms which substantially decreases the volume of space used by the collapsible supporting structure in the collapsed transportable position relative to the useable supporting position.
A substantial benefit in having rotation of the front and rear support legs and attached wheels from a downwardly ground engaging orientation to an upwardly coextensive position with the upright arms is that the weight of articles being supported is on the splayed arrangement with fixed stops providing limited pivotal movement. This means the support is not based on release catches or the like which would have to be substantially stronger and more complex than in the rotation version.
However the invention in the broadest sense provides this mounting of the front and rear legs and upright arms from a central mounting body in such a manner the legs and arms can be moved to a substantially coextensive position to minimise carrying volume.
In order that the invention can be more readily understood an embodiment will be described by way of illustration only with reference to the drawings wherein:
Referring to the drawings there is shown a collapsible supporting structure in the form of a stroller or push chair 11.
The structure includes a mounting body 15 and two rear elongated support legs 18 and 19 and a front support leg 20. The support legs are pivotally connected to and extend from the mounting body 15 in substantially equiangular arrangement with ground engaging wheels 21 attached to each respective distal end. The arrangement of the rear support legs 18 and 19 in the supporting position as shown in
The mounting body 15 is a substantially paralleliped block having substantially parallel planar front and back surfaces with height and width greater than the depth and with opposing outwardly curved top and bottom sides. The internal structure of the mounting body is honeycombed to provide a strength that is suitable to form the supporting central body that can receive weight from structures mounted thereon and stably pass the weight to the supporting legs and the ground engaging wheels.
The mounting of the support legs 18, 19, 20 to the mounting body 15 are by connection means which have two operative systems. The first operative system of the connection means is a rotation means. The second operative system is a pivotal system.
The rotation means includes a rotating cylindrical disc 41 mounted in the centre of the mounting body 15 and having planar circular front and back faces that are substantially coplanar with the front and back respectively of the mounting body 15. The rotating disc 41 is able to rotate therein around an axis that is normal to the front surface of the rotating disc and mounting block.
An end of each of the support legs 18, 19 and 20 are connected to the rotating disc 41 allowing rotation of each support leg. At least one of the support legs is mounted on each side of the disc of the mounting body allowing for rotation of the attached support legs at the same time. The disc has two parts each with an outside surface and an interconnecting part. The rotation means is mounted in a cavity in the mounting body with the two interconnecting parts engaging each other within the cavity and the two outside surfaces being visible from the outside of the mounting body and able to have support legs attached thereon.
The rotation means enabling simultaneous rotation of legs on either side of the mounting body. The rotation means can include locking means to selectively allow simultaneous rotation or separate rotation or independent rotation.
The second operative system being a pivotal system includes a pivoting means made integral with the connection of the support legs 18, 19 and 20 to the rotating disc 41. This pivoting means for the front support leg 20 comprises a U-shaped pivot guard bracket that has the flat central part attached to the front surface of the rotating disc 41. A pivot pin 52 extends between the sides of the U shaped pivot guard bracket and connect through the base end of the cruciform shaped front support leg 20 to allow pivoting movement thereof. The pivot guard performs further function of limiting sideways flex of the front support leg 20 and still further includes a limiting shoulder piece 53 to limit the amount of pivot of the support leg 20 in one direction relative to the mounting body 15. In this way the pivoting means allows the support leg to pivot to the required splayed supporting position while allowing the support leg to move in towards the mounting body.
The supported structure which is to be supported by the mounting body 15 and the support legs 18, 19 and 20 and wheels 21 are based on upwardly extending arms 35 and 36 mounted on the mounting body. The mounting body 15 apart from having the central rotating disc 41 has side sheaths 45 and 46 on either side of the mounting body which have substantially the same height and depth as the mounting body 15. The internal cavities of the side sheaths are substantially V shaped with a pivot pin near the bottom to connect with and pivotally hold the base of the upright elongated arms 35 an 36 so that the upright arms can pivot from a position alongside one side of the V-shape to a position alongside the other side of the V-shape.
It can be seen particularly in
The upright extending arms 35, 36 comprise lower arm 35a, 36a connected to and extending from the mounting body 15 and joined by respective elbow joints 38 to upper arms 35b, 36b and topped respectively by handles 39. The elbow joints 38 and shape of the upper arms 35b, 36b allow the upright arms to extend substantially in the plane formed by the reclining angle of the mounting body 15.
A support frame 45 in the form of a seat is mounted on the upright arms 35, 36 for supporting a child or other load. This is provided by support posts 61, 62 mounted hingedly on the front of the arms 35, 36. The load can rest against flexible material or other rigid material extending between the posts 61, 62 and flexible material or other rigid material extending between the lower arms 35a, 36a. However a fixed structure such as a car baby capsule or a golf club bag can fit directly onto the framework formed by the support posts and upright arms and even the support legs.
Looking at the operation of the rotation means in detail with reference to
To prevent accidental rotation of the rotating disc 41, a twist lock 75 is mounted on the top surface of the mounting body 15 between the upright arms 35, 36 which has a first length with abutment ends 76 where the first length is sufficient to have the abutment ends 76 engage the upright arms 35, 36 in a maximum converging position defined by the limitations of movement within the V-shaped cavity of the side sheaths 45, 46. By the twist lock having a smaller length and being able to rotate and thereby disengage the upright arms, the arms are able to pivotally converge and act in opposition to the spring loaded plungers 82 and thereby allow rotation of the rotating disc 42 and attached front and rear support legs.
Therefore it can be seen that the stroller or push chair 11 includes a plurality of elongated linear support legs 18, 19, 20 with each connected to and extending from the mounting body 15. The legs are arranged having one front support leg 18 extending from a front portion of the mounting body 15 and two support legs 19, 20 extending from a rear portion of the mounting body 15. The stroller or push chair 11 further includes two linear upright arms 35 36 with handles at an upper end and connected in pivotal arrangement within the cavity of the mounting block 15.
Each of these features is capable of movement. The front support leg 20 is able to pivotally move from an outwardly splayed position to a position substantially adjacent the plane of the mounting body and upright arms. The limiting shoulder piece prevents movement in one direction but allows movement in the other direction. If the plane of the mounting body 15 and upright arms 35, 36 is identified as b-b and is at a reclining angle b° to the vertical then the angle of the front support leg along a-a is at an angle a° to the plane b-b and can pivotally move to coextend substantially parallel to the plane b-b. The front support leg is also able to rotate 180° with the rotating disc 41 of the mounting body 15. In this way the ground engaging wheel can extend from a lower side of the mounting body to be on an upper side of the mounting body 15.
The rear support legs 18, 19 are also able to pivotally move from an outwardly splayed position to a position substantially adjacent the plane of the mounting body and upright arms and rotate 180° with the rotating disc 41 of the mounting body 15. That is they can move from a line c-c at an angle of c° to the plane b-b and can pivotally move to coextend substantially parallel to the plane b-b.
The support posts 61, 62 extending from the lower arms 35a, 36a are able to pivot back to be adjacent and coextensive with the lower arms 35a, 36a. They extend along plane d-d which is substantially at right angles to the plane b-b and can pivotally move to coextend substantially parallel to the plane b-b.
The upright arms 35, 36 extend upwardly from the mounting block 15 in the plane of b-b. However the V shape cavity of the outer side sheaths allow movement of the upper arms 35 36 from outwardly converging along line e-e as shown in
The internal side walls of the cavity of the mounting block 15 provide a maximum lateral divergence of the upright arms 35, 36 when in use in a supporting arrangement. The pivotal connection allows the upright arms 35, 36 to converge to substantially coextend for a smaller volume transportable position. In use the upright arms 35, 36 allow for manoeuvrability of the stroller or push chair 11.
In use the stroller or push chair 11 is changeable from a first supporting position in which the support legs 18, 19, 20 extend in a first direction and allow loads to be supported on the collapsible supporting structure to a second transportable position in which the support legs extend in a second direction substantially coextensive with the upright arms 35, 36 and allow ready transportability. The mechanism for such operation is detailed herein.
Each of the support legs 18, 19, 20 are connected to the one mounting body 15 by connection means having rotation means and pivoting means such that the support legs can extend from the mounting body in a first splayed arrangement which forms the supporting position of a load to a second arrangement in which the support legs are pivoted inwards to substantially extend alongside the mounting body and rotated such that the support legs extend substantially alongside the upright arms.
The rotation means allows the support legs 18, 19, 20 to move from the first supporting position to the second transportable position by being rotated. The amount of rotation is up to 180° such that the first supporting position is opposite the second transportable position. This allows for substantial co-extension of the support legs 18, 19, 20 and the upright arms 35, 36 which substantially decrease the volume of space used by the stroller or push chair 11 in the collapsed transportable position relative to the useable supporting position.
The pivoting means of the connection means allows for pivotal movement of the attached support legs 18, 19, 20 from a supporting position at an angle to the mounting body to a collapsible position adjacent the mounting body.
One form of the systematic steps for conversion from the first supporting position allowing loads to be supported on the collapsible supporting structure to a second transportable position is by:
Clearly some of these steps can be undertaken in different orders.
The supporting frame 45 of the stroller or push chair 11 is a seating system which can be modified from a voluminous supporting structure to a minimised volume transportable structure. The supporting frame is mounted on the upright arms 35, 36 of the stroller or push chair 11.
As shown in

Clearly variations of the collapsible supporting structure as would be understood by a person skilled in the art without any inventiveness are included within the scope of this invention as defined in the following claims.
