Description

    FIELD OF THE INVENTION
  • The present invention relates to a rail device which has a frame inserted below the mattress and the bars of the rail device can be folded to be a compact assembly. [0001]
    • BACKGROUND OF THE INVENTION
  • A conventional playpen is used to let a baby sleep or crawl therein so that it has a bottom and four side rails. The side rails are cooperated with fabrics so that the baby can not crawl over the side rails and is safe in the playpen. When the baby grows, the playpen is small for the baby so that the adults could put the baby on a bed and keep an eye on the baby who is vigorous and tries to crawl out from the bed. It is necessary to have a rail device that can be connected to a side of the bed so that the baby cannot crawl out from the bed. However, the conventional rail device involves a complicated structure and a lot of parts. The size of the conventional rail device is so huge that the mother of the baby feels inconvenient to install or removed the rail device from the bed. [0002]
    • SUMMARY OF THE INVENTION
  • In accordance with one aspect of the present invention, there is provided a rail device which comprises a U-shaped frame having two ends thereof respectively connected to two respective connection devices. Each of the connection devices has a first plate and a second plate between which a first tube is pivotally connected. Each of the first plate and the second plate has a notch defined therein. A first transverse bar is pivotally connected between the two second plates of the two connection devices, and a second transverse bar is pivotally connected between the two first tubes. Each of the first tubes has a first pin extending therethrough and two aligned slots defined through a wall of each of the first tubes. A spring is received in each of the first tubes and a first end of the spring contacts the first pin and a second end of the spring is engaged with a stop member. A second pin extends through the stop member and two ends of the second pin movably extend through the two slots in each of the first tubes. The two ends of the second pin are engaged with the two notches in the first plate and the second plate. [0003]
  • The primary object of the present invention is to provide a rail device that can be easily folded and is installed with or disengaged from the bed. [0004]
  • The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.[0005]
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view to show the rail device of the present invention. [0006]
  • FIG. 2 is an exploded view to show a first tube and a connection device of the rail device of the present invention. [0007]
  • FIG. 3 is a cross sectional view to show the connection of the first tube and the connection device of the rail device of the present invention. [0008]
  • FIG. 4 is a side view to show the first tube is pivoted relative to the connection device of the rail device of the present invention. [0009]
  • FIG. 5 is an exploded view to show a connector and two tubes composed of the second transverse bar of the rail device of the present invention. [0010]
  • FIG. 6 is an exploded view to show the rail device is folded and the frame is separated into sections.[0011]
    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIGS. [0012] 1 to 3, the rail device of the present invention comprises a U-shaped frame 12 having two ends thereof respectively connected to two respective connection devices 1, and the frame 12 is inserted beneath the mattress 2 as shown in FIG. 1. The frame 12 is composed of four sections which are convenient to be stored as shown in FIG. 6. Each of the connection devices 1 has a first plate 111 and a second plate 1112 between which a first tube 130 is pivotally connected by inserting a pin 15 through holes 115 in the first plate 111 and the second plate 1112, and a hole 133 in the first tube 130. Each of the first plate 111 and the second plate 1112 having a notch 1110/11120 defined therein. Each of the second plates 1112 has a support port 11121 extending therefrom and a first transverse bar 12A is pivotally connected between the two support ports 11121 on the two second plates 1112. The first transverse bar 12A is connected to the two respective support ports 11121 by a resilient pin 12A1 so that when pushing the resilient pins 12A1 inward, the first transverse bar 12A can be disengaged from the two respective support ports 11121.
  • Each of the [0013] first tubes 130 has a first pin 132 extending therethrough and two aligned slots 131 are defined through the wall of each of the first tubes 130. A spring 114 is received in each of the first tubes 130 and a first end of the spring 114 contacts the first pin 312 and a second end of the spring 114 is engaged with a stop member 112 received in the first tube 130. A second pin 113 extends through a passage 1121 of the stop member 112 and two ends of the second pin 113 movably extend through the two slots 131 in each of the first tubes 130. The two ends of the second pin 113 are engaged with the two notches 1110, 11120 in the first plate 111 and the second plate 1112 so that the first tubes 130 are positioned vertical to the frame 12. Two knobs 1131 are connected to the two ends of the second pin 113 so that the user may hold the knobs 1131 to lift the stop member 112 and the second pin 113 is removed from the notches 1110, 11120. By this way, the first tubes 130 can be folded away the frame 12 as shown in FIG. 4 and this status is convenient for the adult to hold the baby.
  • A second [0014] transverse bar 13 composed of two second tubes 134 is pivotally connected between the two first tubes 130. The two second tubes 134 are connected to the two respective first tubes 130 by two pivotable joints 135. Two respective first ends of the two second tubes 134 are respectively connected to the two pivotable joints 135 and two respective second ends of the two second tubes 134 are pivotally connected to a connector 31 as shown in FIG. 5 by inserting a pin 312 through holes 311 in the connector 31 and holes 1340 in the second tubes 134. The connector 31 has an aperture 310 and a top member 32 is mounted to the connector 31. The top member 32 has a push plate 321 pivotally extending therefrom which is located in alignment with the aperture 310. Two V-shaped biasing members 33 are respectively received in the two respective second ends of the two second tubes 134. Each of the biasing members 33 has an end extending from the second end of each of the second tubes 134 and can be pushed inward by the push plate 321 via the aperture 310. Each of the biasing members 33 has a position pin 331 which is movably inserted through a hole 1340 in each of the two second tubes 134. When the end of the biasing member 33 is pushed inward by the push plate 321, the two second tubes 134 can be pivoted relative connector 31 and folded to be a compact status as shown in FIG. 6.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention. [0015]
