Definitions

  • the present invention relates to a structure of rails, and in particular to a rail that is formed with a design of a frame and a resilient web to provide a barrier for protection purposes thereby ensuring a safe and comfortable environment particularly for families with babies, nurseries, sick beds, and the likes.
  • a sickbed or a baby playpen is often provided with one or more rails to prevent the patient or baby from falling, in order to ensure protection of the patient and the baby.
  • the rail is made by weaving wires or threads to form a net-like article.
  • Others use a piece of cotton cloth or even curtain surrounding around a frame to form a web serving as a protection barrier.
  • the material of web the web may be air impermeable for a cloth web, or for a net-like web, the web may cause potential risk if the curiosity of a baby about the wire makes the baby play with the wires.
  • the wires used to make the web may cause other potential risks, such as stumbling.
  • rails comprising cotton cloth or curtain
  • other risk may exist when the rail falls or gets loosened by a baby's attempt to climb up the cotton cloth or curtain.
  • the conventional web of the rail lacks extensibility and stretchability, which makes the rail incapable to resist against an external force applied thereto, and may thus trap a user in a dangerous condition.
  • a barrier or rail is also required for the door of a baby room to prevent the baby from crawling out of the baby room.
  • a door rail is often mounted in a door frame to protect the baby.
  • the door rail is made of similar materials discussed above, namely wires, cotton cloth, and curtain. Similar potential risks exist when the baby's curiosity drives the baby to climb the rail, pull or play the wires. Further, stumbling may accidentally happen to general users. In addition, falling or collapsing of the rail may happen when the baby pulls the cloth or curtain web. Further, the conventional web of the door rail lacks extensibility and stretchability, which makes the rail incapable to resist against an external force applied thereto, and may thus trap a user in a dangerous condition.
  • the present invention is aimed to provide a rail that is safe and comfortable to prevent babies or children from being trapped in the above discussed risks or dangers.
  • An objective of the present invention is to provide a rail featuring safety and variability, which is realized by a web made of resilient fabric to allow for adjustment of dimension to be fit for bed or door frame of different sizes.
  • Another objective of the present invention is to provide a rail comprising a frame comprised of a plurality of frame bars to which a resilient web of stretchability is attached for distributing around an external force when the web is subjected to the application of the external force, thereby enhancing overall practicability.
  • a further objective of the present invention is to provide a resilient web, which comprises a resilient fabric made of resilient yarns and nylon yarns to feature four-direction stretchability with reduced risk of break of yarns, for combination with a rail to form a protection structure so as to enhance the practicability and convenience.
  • Yet a further objective of the present invention is to provide a resilient web that features excellent water absorbability and is easy to dry for combining with a rail to form a safety barrier.
  • a rail comprising a frame and a resilient web.
  • the frame comprises a plurality of frame bars.
  • the resilient web surrounds and is mounted to the frame bars to form a resilient central web of stretchability among the frame bars.
  • Figure 1 is a perspective view of a rail constructed in accordance with the present invention
  • Figure 2 is an exploded view of the rail of the present invention
  • Figure 3 is a perspective view of a first embodiment of the rail of the present invention.
  • Figure 4 is a perspective view illustrating an application of the rail of the first embodiment of the present invention.
  • Figure 5 is a perspective view of a second embodiment of the rail of the present invention.
  • Figure 6 is a perspective view illustrating an application of the rail of the second embodiment of the present invention.
  • a rail constructed in accordance with the present invention comprises a frame 10 and a resilient web 20.
  • the frame 10 comprises a plurality of frame bars 11 between adjacent ones of which a corner member 30 is arranged for connecting the frame bars 11 together.
  • the resilient web 20 surrounds the frame bars 11 to form a web portion among the frame bars 11.
  • the resilient web 20 is made of resilient yarns and nylon yarns, which are woven together.
  • the resilient yarns are single filament yarns
  • the nylons yarns are composite yarns comprising a plurality of filaments entangled together.
  • An example of the composite yarns is made of 24 filaments entangled together.
  • the ratio between the resilient yarn and the nylon yarn is 15:85 with a tolerance of ⁇ 2%.
  • the diameter (denier) of the resilient yarn can be for example 30, 40, 55, 77 or other suitable ones, while that of the nylon yarns can be for example 30, 40, 55, 70, 140, 210, 280, 560, 840 or other suitable ones.
  • the resilient web 20 is formed by a fabric that is made by warp knitting of the yarns, wherein the yarns are subjected to lateral movement of performing the weaving, so that the resilient web formed of the fabric so made is of four-directional stretchability and thus enhanced extensibility with reduced risk of yarn breaking. Due to the nylon components of the resilient web 20, the resilient web 20 features enhanced water absorbability and is easy to dry.
  • the resilient web 20 can be made of a fabric that is made by plain weaving in which warp knitting and weft knitting are alternately employed. Further alternately, the resilient web 20 can be formed in a net-like structure to ensure excellent air permeability.
  • the rail of the first embodiment comprises a frame 10 and a resilient web 20.
  • the frame 10 comprises a plurality of frame bars 11 between adjacent ones of which a corner member 30 is arranged for connecting the frame bars 11 together.
  • At least one frame bar 11 of the frame 10 includes, at a middle section thereof, an extension device 40 for selectively extending/contracting the frame 10.
  • transverse bars also designated with reference numeral 11 for simplicity, are attached.
  • Each of the joints of the lower frame bar 11 is provided with a collapse device 12, which comprises a connection block 121.
  • connection block 121 and an upright one of the frame bars 11 positioned thereabove are operatively coupled to an operation ring 122 and the frame bar 11, which is tubular, contains therein a spring 111 or other resilient elements and a stop block 112 operatively coupled to the operation ring 122 whereby when the operation ring 122 is moved upwards and disengages from the connection block 121, the associated transverse bar 11 is allowed to fold.
  • the corner members 30, the frame bars 11, and the collapse devices 12 together construct a three-dimensional bed-side protection rail, as shown in Figure 3 , with the resilient web 20 surrounding the frame bars 11 to form a resilient central web of stretchability among the frame bars 11 of the frame 10; and the resilient web 20 features four-directional stretchability, which gives the web enhanced extensibility with reduced risk of yarn breaking.
  • the resilient web 20 Due to the component of nylon of the resilient web 20, the resilient web 20 features excellent water absorbability and is easy to dry.
  • the web 20 can be constructed in the form of a net to ensure excellent air permeability.
  • the transverse bars 11 extending from the jointing corners of the lower frame bar 11 allows the rail to be positioned and retained below a bed mattress 50, as shown in Figure 4 , to provide a safe and comfortable bed-side rail.
  • FIGS 5 and 6 illustrate a second embodiment of the rail structure in accordance with the present invention, which is applicable to a door frame rail to prevent a baby or a young child from leaving a room to which the door frame is mounted.
