Abstract

A foldable baby crib comprising a flexible enclosure adapted to accommodate a baby, an upper frame for supporting the enclosure along its upper edge, and two support structures connected to the upper frame to hold the enclosure in a lifted position. The upper frame comprises two half-parts which are pivotally articulated to each other at two junction devices and are pivotally articulated each to a respective support structure. The support structures, which are initially spaced apart from each other, move toward each other as the crib is being closed, while the half-parts of the upper frame pivot relative to each other and to the support structures. The two junction devices of the upper frame are spaced apart from each other both in the open configuration and in the closed configuration of the crib at a substantially constant distance.

Description

FIELD OF APPLICATION

The present invention relates to a baby crib that can be collapsed into a storage configuration.

DISCUSSION OF THE RELATED ART

Baby cribs are objects that may have a large size. Therefore, foldable cribs are greatly appreciated, as they may have a smaller footprint and be possibly made of light-weight and flexible materials. The collapsible nature of a crib facilitates packaging for sale, transportation also by a user, and storage when its use is no longer needed.
Cribs according to a patent application by the Applicant hereof are currently available, in which a flexible enclosure for receiving a baby is connected to an upper frame which extends along the upper edge of the enclosure. The upper frame comprises two pivotally connected C-shaped half-parts, which are initially arranged with the concavities of the C shapes oriented in opposite directions, toward each other. Four legs, which are fixed to each other in pairs, support the upper frame above a support surface.
In order to reduce the dimensions of the crib, the legs must be first separated from the upper frame. Then, the two half-parts of the upper frame pivot toward each other into a configuration in which the concavities of the C shapes are oriented in the same directions.
The document U.S. Pat. No. 8,650,678 shows a playpen with a folding frame. In the open configuration, the upper frame defines a quadrilateral, in which each side comprises a pair of mutually pivoting articulated arms. Four legs are vertically arranged and support the pairs of arms of the upper frame at the vertices of the upper frame. A lower frame, which is adapted to support a bottom of the playpen comprises a central connection device and additional arms arranged to form a X shape, which connect each leg to the connection device.
As the playpen is being closed, the connection device is lifted. At the same time, the arms of the lower frame pivot upwards and the pairs of arms of the upper frame pivot downwards. Thus, the four legs move toward each other in the direction of the connection device. This will considerably reduce the length and width of the playpen, while its height is unchanged and corresponds to the height of the legs. These movements are coordinated by a transmission system, which extends from the connection device along all the parts of the crib frame.

PRIOR ART PROBLEM

In the prior art crib of the Applicant, the closing movement causes the legs to be separated from the upper frame, and the container for housing all the parts of the frame must be kept for storage or transportation of the crib. Furthermore, as the crib is reopened, its legs must be reconnected each time to the upper frame.
In U.S. Pat. No. 8,650,678, as the playpen is closed, a large number of arms are simultaneously moved. A user would hardly coordinate the movements of all the arms at the same time, therefore a complex mechanism is required enabling the user to control simultaneously all these movements by only acting on the central connection device, which can be only accessed once the bottom of the playpen has been removed.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a crib that may be easily folded into a closed configuration while obviating the aforementioned prior art problems, Particularly, the object of the invention is to provide a crib that may be collapsed using a simple mechanism, without requiring separation of the parts of the frame or removal of a bottom of the crib.
These and other objects are fulfilled by a baby crib as defined in any of the accompanying claims. In the crib of the invention, an upper frame, which is configured to support the enclosure of the crib, comprises two half-pats that are pivotally articulated to each other at two junction devices. Two support structures support the upper frame and each of them is also pivotally articulated to a respective part of the upper frame.
As the crib is being closed, each half-part of the upper frame simultaneously pivots relative to its respective support structure and to the opposite half-part, while the two support structures move toward each other. Therefore, the legs need not be separated from the upper frame, which leads to simplified crib closing, transportation and reopening operations.
As the crib is being closed, the junction devices of the upper frame remain in spaced apart position and do not move toward each other. Therefore, the crib is only collapsed in one direction, and substantially maintains its original with and height. Namely, the crib is closed by simply manually acting in two points of the upper frame, for instance at the junction devices, and no complex mechanism is needed for coordinating all the arms of the crib. Furthermore, the enclosure may be always connected to the crib, which avoids the need to remove its bottom. The crib still has a small size in its closed configuration, which allows it to be placed, for instance, behind a door.

DETAILED DESCRIPTION

The figures show a baby crib according to the invention, generally designated by numeral 1. The crib 1 comprises a flexible enclosure 20, preferably made of a textile material, which delimits a room that is adapted to receive a baby when the crib 1 is in an open configuration. As more clearly explained hereinafter, the crib 1 may be also folded into a closed configuration, in which the enclosure 20 is generally not suitable to accommodate a baby.
The enclosure 20 has a bottom wall 21 for supporting a mattress, and side walls 22 which extend from the bottom wall 21 to an upper edge 23 of the enclosure 20. The bottom wall 21 and the upper edge 23 may have, for example, a rectangular or elliptical shape, and define a plurality of rectilinear or curvilinear sides of the crib 1.
The crib 1 also comprises an upper frame 30 which is configured to support the enclosure 20, and generally comprising a plurality of rectilinear or curvilinear rod-like elements, arranged along the sides of the crib 1. Particularly, the upper frame 30 extends along the upper edge 23 of the enclosure 20, and the enclosure 20 is connected to the upper frame 30 at the upper edge 23. For example, the upper edge 23 of the enclosure 20 may be wrapped around the rod-like elements of the upper frame 30, and may be fastened thereto by means of stitching, Velcro, zippers or buttons.
The crib 1 comprises two support structures 40. Each support structure 40 generally comprises one or more legs 41, preferably two legs 41, configured to support the upper frame 30 and the enclosure 20 and keep it raised relative to a support surface in a height direction Z-Z. The support structures 40 are spaced apart in a longitudinal direction X-X when the crib 1 is in the open configuration.
In the preferred embodiment, the two legs 41 of each support structure 40 are fixed together at a constant distance in a direction Y-Y transverse to the longitudinal direction X-X. In the embodiment shown in the figures, each support structure 40 comprises, for this purpose, a transverse rod 42 which extends in the transverse direction Y-Y between the two legs 41 of the support structure 40. Namely, the transverse rod 42 is fixed to the two legs 41 at its ends. The two legs 41 and the transverse rod 42 define together a substantially planar support structure 40 which is transverse, e.g. perpendicular to the longitudinal direction X-X.
The upper frame 30 comprises two half-parts 34. The two half-parts 34 extend along the upper edge of the enclosure 20 and are arranged in opposite positions, preferably having mutually symmetric shapes. The two support structures 40 are each connected to a distinct half-part 34 of the upper frame 30.
Particularly, each half-part 34 is formed as a substantially planar C-shaped rigid structure, which extends along a curved or broken line, as shown in the figures. Each half-part 34 comprises two end portions 36 which are spaced apart in the transverse direction Y-Y. The end portions 36 of each half-part 34 are connected to the opposite half-part 34.
In the preferred embodiment, each half-part 34 of the upper frame 30 comprises a rigid connection rod 32 which connects together the end portions 36, thereby preferably fixing together the end portions 36 at a constant distance. Namely, the two end portions 36 of each half-part 34 extend from a respective connecting rod 32 toward the opposite half-part 34.
In the open configuration, the two half-parts 34 of the upper frame 30 are substantially coplanar, on a plane perpendicular to the height direction Z-Z. More in detail, in the open configuration, the two connecting rods 32 for the two distinct half-parts 34 define two opposite sides of the crib 1, which are spaced apart in the longitudinal direction X-X. The end portions 36 of the half-parts 34 are arranged in the remaining two opposite sides, which are spaced apart in the transverse direction Y-Y.
As mentioned above, in order to reduce the dimensions of the crib 1 for storage, the crib 1 is adapted to switch from an open configuration, which has already been described in some detail, to a closed configuration. The crib 1 is shown in the open configuration of FIGS. 1 and 2, and in the closed configuration in FIG. 3.
The crib 1 comprises two junction devices 35 which are spaced apart in the transverse direction Y-Y. In order to close the crib 1, the two half-parts 34 of the upper frame 30 are pivotally articulated to each other via the junction devices 35 and are adapted to be rotated about an axis of rotation that extends in the transverse direction Y-Y.
In detail, each half-part 34 of the upper frame 30 is connected to the two junction devices 35 at its end portions 36. In other words, the junction devices 35 are located in a distal position relative to the connecting rods 32. More in detail, each junction device 35 comprises at least one pivot pin 3, and each half-part 34 of the upper frame 30 is pivoted to a respective pivot pin 37 of the junction device 35.
Each support structure 40 is further pivotally articulated to a respective half-part 34 of the upper frame 30. Particularly the crib 1 comprises a plurality of hinges 33 and the support structures 40 are connected to their respective half-parts 34 of the upper frame 30 at respective hinges 33. In the open configuration, each hinge 33 associated with a support structure 40 is spaced apart from a hinge 33 associated with the opposite support structure 40 in the longitudinal direction X-X.
In the preferred embodiment, the two legs 41 of each support structure 40 are hinged to their respective half-parts 34 of the upper frame 30 at hinges 33 located at the opposite ends of their respective connecting rods 32. Therefore, in this case, the crib 1 comprises four hinges, which are associated in pairs with respective support structures 40 and half-parts 34 of the upper frame 30. The end portions 36 of the two half-parts 34 are disposed between respective hinges 33 and junction devices 35. Also, each leg 41 is inclined with respect to its respective connecting rod 32, and preferably extends perpendicular thereto.
During transition from the open configuration to the closed configuration, the half-parts 34 of the upper frame 30 are configured to pivot relative to and toward each other, about an axis that extends in the transverse direction Y-Y through the junction devices 35. More in detail, in the closed configuration, each hinge 33 associated with a support structure 40 is close to a hinge 33 associated with the opposite support structure 40. Furthermore, in the closed configuration, the connecting rods 32 are close to each other.
Preferably the half-parts 34 of the upper frame 30 are configured to move the hinges 33, as well as the connecting rods 32, by translating them only in the longitudinal direction X-X during the transition from the open configuration to the closed configuration. At the same time, the half-parts 34 of the upper frame 30 are configured to move the junction devices 35 by translating them in the height direction Z-Z during the transition from the open configuration to the closed configuration.
In the open configuration, the junction devices 35 are substantially coplanar with the peripheral portions 34 of the upper frame, and particularly with the hinges 33 and the connecting rods 32, whereas in the closed configuration the junction devices 35 are situated below the hinges 33 of the upper frame 30 in the height direction Z-Z.
During transition from the open configuration to the closed configuration, the half-parts 34 of the upper frame 30 are configured to also pivot relative to and toward their respective support structures 40, at the same time as the two half-parts 34 pivot relative to each other. Particularly, the end portions 36 of the half-parts 34 pivot toward their respective support structures 40 about an axis that extends in the transverse direction Y-Y through the hinges 33. As a result, the support structures 40 move toward each other in the longitudinal direction X-X with a substantially translational motion, whereby the support structures 40 are close to each other in the closed configuration. Particularly, during transition from the open configuration to the closed configuration, each leg 41 of each support structure 40 only translates in the longitudinal direction X-X.
In one aspect of the invention, the half-parts 34 of the upper frame 30 are configured to keep the distance between the junction devices 35 in the transverse direction Y-Y substantially constant during transition from the open configuration to the closed configuration. In other words, the distance between the junction devices 35 in the open configuration is substantially equal to the distance between the junction devices 35 in the closed configuration.
As used herein, the transition from the open configuration to the closed configuration is always intended as the specific step in which the half-parts 34 pivot relative to each other and/or to their respective support structures 40 and/or in which the support structures 40 move toward each other to cause the crib 1 to transition from the open configuration to the closed configuration.
However, it is not excluded that further precedent or subsequent steps may be provided for bringing a crib 1 according to the invention from the open to the closed configuration. Particularly, the mention to a distance or an angle that is kept constant during transition from the open configuration to the closed configuration does not exclude that such distance or angle may be changed through additional closing steps, other than the one as mentioned above.
In the same manner as mentioned above for the junction devices 35, during transition from the open configuration to the closed configuration, a constant distance is also kept between the two legs 41 of each support structure 40, which are fixed together at a constant distance by the connecting rods 32 and the transverse rods 42, and a constant distance is further kept between the hinges 33 associated with the same support structure 40.
Furthermore, during transition from the open configuration to the closed configuration, each leg 41 of each support structure 40 is inclined with respect to its respective connecting rod 32 at a constant angle. The connecting rod 32 mainly extends in the transverse direction Y-Y in both open and closed configurations, and each connecting rod 32 and its respective legs pivot relative to each other about an axis that extends in the transverse direction Y-Y, i.e. in the direction of extension of the connecting rod 32. Therefore, during the transition from the open configuration to the closed configuration, the connecting rod 32 rotates on itself between the hinges 33.
This will simplify the closing mechanism of the crib 1 as compared with cribs or playpens in which the connecting rods 32 are replaced with articulated structures that cause the legs 41 of one support structure to move toward each other in the transverse direction Y-Y. Therefore, a complex crib-closing mechanism that can be only accessed after removal of the bottom of the crib 1 will not be needed.
It will be appreciated that the two support structures 40 are substantially parallel to each other in both open and closed configurations, as they are both perpendicular to the longitudinal direction X-X. Furthermore, in the closed configuration, both support structures 40 are also parallel to the two half-parts 34 of the upper frame.
In order to prevent the crib 1 from being accidentally closed, each junction device 35 comprises a first lock mechanism 50, which is configured to prevent the half-parts 34 of the upper frame 30 from pivoting relative to each other, and particularly from pivoting relative to the junction device 35. More in detail, a first lock mechanism 50 is provided for each end portion 36 of the half-parts 34 of the upper frame 30. In order to illustrate the characteristics of the first lock mechanism 50, FIG. 4 shows a partially sectional view of the interior of one of the junction devices 35.
In the illustrated embodiment, the lock mechanism 50 comprises a slide guide 51 for each half-part 34, e.g. a slot formed in the junction device 35, whereas the corresponding half-part 34 comprises a projecting member 53 whose shape is conformed for engagement in the guide 51, e.g. a peg projecting in the transverse direction Y-Y from an end portion 36 of a half-part 34. The positions of the guide 51 and the projecting member 52 may be obviously exchanged between the junction device 35 and the half-part 34.
The guide 51 defines a rotation-guiding portion 53 and a lock portion 54. The rotation-guiding portion 53 is shaped to guide the projecting member 52 during rotation of its respective half-part 34 relative to the junction device 35. For example, the rotation-guiding portion 53 may be arc-shaped, with its center at the pivot pin 37 of the junction device 35, about which the respective half-part is pivoted. The lock portion 54 is shaped to receive and lock the projecting member 52 to prevent rotation of its respective half-part 34 relative to the junction device 35 when the upper frame 30 is in the open configuration. For instance, the lock portion 54 may be a segment that extends from the rotation-guiding portion 53 toward or away from the pivot pin 37.
Each first lock mechanism 50 comprises an elastic member 55 which is configured to hold the projecting member 52 in the lock portion 54 of the guide 51 when the upper frame 30 is in the open configuration. In the illustrated embodiment, the elastic member 55 is a spring which is loaded when the projecting member 52 is in the rotation-guiding portion 53 of the guide 51. Thus, the elastic member 55 is configured to move the projecting member 52 into the lock portion 54 of the guide 51 when the upper frame 30 is caused to transition to the open configuration, and preferably operates by extension.
The crib 1 comprises a release actuator 56 for each junction device 35, which is operable to release the first lock mechanism 50 and allow transition from the open configuration to the closed configuration. For example, a release actuator 56 may comprise a button located at a junction device 35 and adapted to slide relative the junction device 35 in the height direction Z-Z.
Particularly, the release actuator 56 is configured to move the projecting member 52 from the lock portion 54 to the rotation-guiding portion 53 of the sliding guide 51, thereby loading the elastic member 55, if any. As shown in FIG. 4, the release actuator 56 comprises inclined surfaces 57, which are designed to convert the translational motion of the release actuator 56, for instance in the height direction Z-Z, into simultaneous translation of all projecting members 52 relative to one of the junction devices 35, for instance in the longitudinal direction X-X when the crib 1 is in the open configuration.
Each half-part 34 of the upper frame 40 comprises a second lock mechanism 60 which is configured to prevent its half-part 34 from pivoting relative to its respective support structure 30. Particularly, a second lock mechanism 60 is provided for each hinge 33, where one half-part 34 of the upper frame 30 and a support structure 40 are connected. FIGS. 5 and 6 show an example of the second lock mechanism 60.
In the preferred embodiment, each second lock mechanism 60 comprises a gear wheel 61 which is designed to simultaneously mesh with toothings 62 of a support structure 40 and a half-part 34 of the upper frame 30, to thereby prevent them from pivoting relative to each other. The toothings 62 may be formed in a cavity of the hinge 33 which houses the gear wheel 61. The gear wheel 61 is adapted to axially move to engage and disengage the teeth 62 of the support structure 40 and/or the half-part 34.
Preferably the second lock mechanisms 60 are adapted to be released by the same release actuators 56 that also release the first lock mechanisms 51. In other words, the release actuators 56 of the junction devices 35 are configured to release their respective first and second lock seconds mechanism 50, 60 and allow transition from the open configuration to the closed configuration.
For this purpose, the second lock mechanisms 60 are connected to the first lock mechanisms 50 via cables 53 which extend inside the peripheral portions 34 of the upper frame 30. Namely, the cables 63 are connected to the first lock mechanisms 50, so that the release of the first lock mechanisms 50 will cause the cables 63 to be tensioned and the second locking mechanisms 60 to be released. For example, the cables 63 may be connected to the first lock mechanisms 50 at the elastic members 55, which are loaded upon actuation of the release actuator.
Therefore, each second lock mechanism 60 comprises a release member 64, which is actuated by the cable 63 to disengage the gear wheel 61 from at least one of the toothings 62 of half-part 34 or of the support structure 40, for example by axially pushing the gear wheel 61 against the action of a spring (not shown). Particularly, the release member 64 is a disk accommodated between the half-part 34 and the leg 41, besides the gear wheel 61 and coaxial with the gear wheel 61. Such disc is adapted to be rotated as the cable 63 is tensioned, and its rotation generates an axial thrust on the gear wheel 61 due to the action of cooperating inclined surfaces 65 formed in the disk and in the half-part 34, or in the support structure 40. The axial displacement of the release member 64 disengages the gear wheel 61 from the toothing 62 of the half-part 34, thereby allowing mutual rotation of the leg 41 and the half-part 34.
In short, the crib 1 is closed by a process in which initially, in the open configuration, the two half-parts 34 of the upper frame 30 are coplanar with each other and substantially perpendicular to their respective support structures 40, while the first and second lock mechanisms 50, 60 are operating. The user actuates the two release actuators 56 at the junction devices 35, thereby releasing the first and second lock mechanisms 50, 60. The two half-parts 34 of the upper frame 30 pivot relative to the junction devices 35 and the support structures 40, while the junction devices 35 are lowered and the support structures 40 move toward each other.
In the closed configuration, the support structures 40 and the half-parts 34 of the upper frame 30 are arranged on planes that are substantially parallel to each other and perpendicular to the longitudinal direction X-X. Therefore, in the closed configuration the crib 1 has much smaller dimensions in the longitudinal direction X-X as compared with the open configuration. However, the crib 1 has substantially the same dimensions in the transverse direction Y-Y in both closed and open configurations.
It shall be understood that, in the closed configuration, the enclosure 20 may be separated from the upper frame 30 or remain connected thereto and be collapsed to minimize its dimensions, due to the flexibility of its material.
A skilled person may obviously envisage a number of changes to the above described variants, without departure from the scope as defined by the appended claims.
