Small children have a natural tendency to climb and explore and do not wish to be restrained in a room or in a crib or playpen. The tendency to climb, of course, creates a number of hazards. Efforts have been made in the past to restrain children such as by the use of products referred to as safety gates.
The problem arises in various environments such as trying to keep children within a room (or excluded from a room, such as a kitchen where hazards exist) or within a play area (such as a crib or playpen or other enclosure) where a climbing child is at risk of falling or at risk of going into an unsafe area after exiting the play area.
The identification of the problems and the proposed solutions will be given in the context of keeping a child on one side of a barrier and/or keeping a child restrained within a play area, it being understood, however, that these are all exemplary and non-limiting.
Passageway barriers, also called child or baby safety gates, are designed to serve as temporary means of closing off access to potentially dangerous or otherwise restricted areas of a house or other domicile or place of business to prevent children or animals from passing beyond the barrier.
There are a great variety of such partitioning barriers available on the market today. Passageway barriers are made of rigid materials, such as wood, molded plastic or metal or a combination thereof. Some of these rigid barriers are stationary and require an adult who wishes to pass through the passageway to either step over the barrier or find a way around the barrier. Examples of such barriers are illustrated in U.S. Pat. No. 4,787,174, issued to Tyrone Brown on Nov. 19, 1988, and U.S. Pat. No. 6,655,087, issued to Jesper Andersen on Dec. 2, 2003. Other rigid-material barriers include a gate, which can be swung open to provide easier passage for adults. Examples of this type of barriers are U.S. Pat. No. 4,685,247, issued to Aftab Alam on Aug. 11, 1987, and U.S. Pat. No. 6,370,823 B1, issued to Finn Andersen on Apr. 16, 2002.
Rigid child safety barriers and/or passageway barriers, however, suffer a number of significant shortcomings. First, they can be large and cumbersome, which lessens their portability. In addition, toddlers or young children may be able to climb many barriers of this type, especially if their barrier panels are comprised of a grid of rigid members or a gridiron of molded plastic. The hazards of climbing these gates by young children are obvious and include the risk of falling as well as children having their fingers or toes getting caught in the grid of barrier panels. Also, repeated attempts to climb the gate can loosen the gate's positioning in its place, thereby reducing its reliability in preventing passage and increasing the risk of injury. This is especially likely for friction-mounted gates, e.g. those that are not permanently fastened to the sides of the passageway with screws or nails but rather held in place by spring-loaded devices. Furthermore, nearly all child safety gates are too tall for most adults to step over. The height of safety gates can significantly raise the risk of injury particularly when the adult tries to step over the gate while carrying a child. Child safety barriers with openable gates are designed to overcome the problem of allowing access by the adult (i.e., authorized access) however, these openable gates require at least one free hand—a significant inconvenience for a person attending to a child—and the latches tend to be too stiff and difficult to operate.
Another common type of passageway barrier makes use of a flexible partitioning screen or membrane that can be releasably extended between the two sides of a passageway. Examples of these types of barriers are illustrated in U.S. Pat. No. 6,375,165 B1, issued to Richard Sherratt, et al on Apr. 23, 2002, and U.S. Pat. No. 7,178,792 B2, issued to Robert Monahan et al. on Feb. 20, 2007. While these barriers pose greater difficulties for the climbing child, it should be appreciated that some children are able to grab the top edge of the partitioning screen and pull themselves up high enough to swing a foot over the top edge for additional leverage and overcome the barrier. This again creates a serious health hazard to the child from falling off the top of the barrier. For the adult, passing through the passageway blocked by a flexible membrane child safety barrier may not be any easier than when a rigid barrier is installed within the passageway. This is because flexible barriers also require at least one free hand to open and close the screen. In fact, some flexible barriers may require two-handed operation. In addition, this type of barrier also cannot be easily and safely stepped over because this type is usually as tall as the rigid type barriers.
Similar problems are encountered with conventional cribs, playpens and play yards. More specifically, most cribs and bounded play areas for small children are designed to ensure that infants and toddlers are unable to climb out. In the case of cribs, for example this often means that they are made sufficiently deep as judged by crib manufacturers. While a greater crib depth may provide added safety, it comes at a cost of significant inconvenience for parents. Laying a sleeping child into a very deep crib often presents a nontrivial physical challenge, as the parent must lean all the way into the bottom of the crib while holding the child in both arms and trying not to wake the child. Until recently some cribs had drop sides, slide-down sides or drop gates designed to address this major inconvenience. However, most such crib designs are no longer considered safe following the changes in crib safety standards in June 2011. In addition, it has been observed that despite the considerable crib depth, some small children are capable of climbing out of the crib as long as they can reach the rim of the crib. Thus, the need for a more effective child safety barrier for keeping children safe within their cribs, playpens, and other play areas is apparent.
For ease of description, the term “barrier” will be used whenever feasible to refer to both child safety barriers of the type which may be placed in a passageway and the type which may be placed on a crib, play area, etc. Exceptions to the foregoing general statement, if any, will be apparent based on the context in which the term “barrier” is used.
Barriers as described below, installed in a passageway, provide an effective way of preventing small children from entering or leaving a restricted area of a house. Unlike most other child safety barriers that can be easily climbed by a child, the barriers as described below include a rotating portion which functions to deny the child climbing leverage even when the barrier is placed relatively low, i.e., close to the floor. This is an important safety advantage because it significantly reduces the possibility of the child falling. The barriers described below provide excellent stability a feature not typically present in friction-mounted barriers.
Furthermore, as noted above, while most prior art passageway barriers, in order to be effective in blocking off household areas, are too tall for most adults to easily step over them as described above, the rotating feature of the barrier described below makes it very difficult for children to climb over. Thus the barrier described below can be installed at a lower vertical level thus allowing significantly greater freedom of movement.
Yet another feature of the barrier described below, when installed on a crib, play pen, play area, etc., provides more safety for infants and toddlers while providing more convenience for the adults attending to the infants and toddlers. On the one hand, the rotating portion of the barrier denies the child climbing leverage while, on the other hand, the barrier may be placed vertically lower (or the mattress of the crib vertically higher) thus making it easier for the adult to place the child in the crib, play pen or the like.
The various embodiments of the barrier described below include at least one rotating portion that allows rotation in one direction only and is mounted such that the rotation occurs “inwardly” in the direction of the area where the child is to be restrained.
The various objects and advantages of the unclimbable barrier will become more apparent upon reading the following detailed description taken in conjunction with the accompanying drawings.

The support rod 16 can be made by forming the rod as first and second (or more) substantially cylindrical rod sections. This provides an option of allowing the length of the rod to be adjustable. Regardless of whether the adjustable feature is desired, if the rod is formed of first and section sections, the second rod section should be made hollow and should have an inner diameter slightly greater than the outer diameter of the first rod section. Accordingly, the first rod section can be telescopically received within the second rod section to a depth that causes support rod 16 to have the desired effective length. One rod section is then twisted relative to the other so as to lock support rod 16 in the obtained length. Optionally, one rod section may be force fit into the other rod section.
Each end of tension bar 16 can include a pressure surface 20, such as a non-slip portion which can be a rubber or non-slip plastic tip. The pressure surface is adapted to bear against the sides of passageway 12 when the barrier is in place to increase the frictional engagement of the barrier 10 across passageway 12 and reduce the possibility of damaging the upright surfaces engaged by support rod 16. Tension bars are well-known in the art and are often used in mounting shower and window curtains.
The length of elongated member 14 can be made adjustable by forming the elongated member from two (or more) telescopically extendable sections as generally illustrated in
Means are provided to ensure that the elongated member 14 spins or rotates around support rod 16 only in one direction. One mechanism for achieving this objective is illustrated in
Ratchet mechanism 30 may include a slanted-tooth sprocket 36, preferably affixed to the walls of lumen 18 of elongated member 14, and a plurality of ratchet flanges 34. The teeth 38 of slanted-tooth sprocket 36 have a ramp slope at one edge and a steep abutment (e.g. 90°) at the opposite edge, so that the ratchet flanges 34 tend to slip when elongated member 14 is rotated in the releasing direction and jam against the steep abutment of teeth 38 when elongated member 14 is rotated in the locking direction. The teeth 38 are illustrated for example in
If the elongated member 14 is formed of a pliable or flexible material, or utilized with a rod 16 having one or two spring loaded ends (i.e., a tension rod) the barrier may be installed between uprights by compressing one (or both) ends of the elongated member 14 axially inwardly. This will expose the support rod 16 such that the support rod may be positioned within the vertical uprights (e.g., a door jab). The length of the support rod is next adjusted and the ends of support rod 16 are positioned against the sides of the installation site, such as passageway 12—the adjustment of the length is such as to provide sufficient tension for secure mounting. The two rod sections are twisted relative to each other (one or both may be twisted) to lock the two rod sections at the desired length. Then the ends of elongated member are released such that they substantially cover support rod 16 within.
The barrier should be positioned horizontally or at least substantially horizontally between the vertical portions of the passageway.
As an alternative, the rod 16 may be made of a fixed length commensurate with the width of a standard interior house door opening.
As another alternative, as illustrated in
In the alternative described in the preceding paragraph, the sprocket 36 must be formed of multiple parts that make up a single unit when the two parts of elongated member 14 are brought together.
The barrier 10 does not require an internal support rod 16.

It should be appreciated that the various attachment mechanisms are illustrative and non-limiting in nature. The proposed location of the barrier may result in one attachment mechanism be preferred over other attachment mechanisms. For illustrative, non-limiting purposes only, it should be appreciated that safety barrier installation sites, such as a hallway, stair landing, corridor, entrance to a room or other household area, may make one type of barrier end more suitable than another. Thus, for example, mounting plates 24 may be preferred for a more permanent installation of barrier 10 against flat walls or doorposts, while bands 22 may be preferred for maintaining barrier 10 across the balustrades or newel posts of a staircase.
As another attachment option, a smooth drum 60 may be fitted within an aperture 62 in the elongated member, again through the use of a rivet 54 with one end of the rivet received within an axial aperture 64 in the elongated member. In the embodiment of

Generally, it is preferred to provide sufficient tension across the blocking member 70 so as to provide a relatively solid blocking effect, i.e., a blocking which is not easily overcome by a child or small animal attempting to move through the passageway. The degree of tension may optionally be made adjustable and, for this purpose an optional tension wheel 90 is provided at the base of vertical support 72. As illustrated in detail in
A barrier 10 may be utilized to assist in restraining a child within a crib, play pen, play area or the like. For ease of understanding, the barrier is illustrated as being installed adjacent to (e.g. just above) a horizontal rim of a crib 13. It is preferable that barrier 10 is installed on one of the two longer sides of crib 13. It is also preferable that the barrier installed on a crib or the like include a ratchet mechanism 30 that allows elongated member 10 to spin or rotate only towards the inside of crib 13, i.e. only in the direction of the arrow on the drawing, in order to further reduce the likelihood of the child falling or climbing out of the crib. In the embodiment of
It should be appreciated that barrier 10 may be installed upon cribs, play pens, enclosed play areas or the like by means of various attachment mechanisms. An example of a method of attaching barrier 10 to crib 13 is also illustrated in
The foregoing is a complete description of various embodiments of the barrier. The foregoing description, however, should be interpreted as illustrative and non-limiting, i.e., the foregoing exemplifies several non-limiting embodiments. Accordingly, the scope of the present invention should not be limited by the embodiments but only by the appended claims and such equivalent as are applicable under the law.
