Definitions

  • the present invention relates to a rotatable and positionable guardrail joint structure for particularly use in a guardrail structure of a bed such as a baby bed, a sickbed or the like.
  • the guardrail structures are usually mounted beside baby beds and sickbeds to protect young children or patients from the risk of fall.
  • the guardrail structure is previously made of iron tubes and fixed securely by welding process.
  • the welding process results in high production cost.
  • a composite-type guardrail structure is thus disclosed.
  • a joint structure and a rod are formed integrally, and these integrally formed joint structure and rod are then coupled with other integrally formed joint structures and rods.
  • this composite-type structure takes much time for assembly in spite of reducing the production cost.
  • the required storage space of the composite-type guardrail structure cannot be reduced without completely detaching the joint structures from the rods.
  • the pivotal connection means that pivotally couple with each other, the corresponding shaft and shaft hole, and the projecting lug and rib that block each other.
  • a guardrail joint structure comprises: an upper arm having a pivotal connection means on one end thereof, a coupling device on the other end thereof and a projecting lug on the pivotal connection means; and a lower arm having a pivotal connection means correspondingly on one end thereof, a coupling device on the other end thereof and a rib on the pivotal connection means, wherein the pivotal connection between the pivotal connection means of the upper arm and the pivotal connection means of the lower arm makes the guardrail joint structure rotatable and foldable, and wherein the upper arm and the lower arm can be positioned by using the projecting lug and the rib.
  • a guardrail joint structure of the present invention comprises an upper arm 10 and a lower arm 20.
  • the upper arm 10 has a disk-shaped pivotal connection means 11 having a shaft 111 on the center.
  • the shaft 111 has a through hole 112 on the center.
  • a projecting lug 113 is located on the pivotal connection means 11 beside the shaft 111, wherein the projecting lug 113 may be hollow inside depending on requirements.
  • a projecting flange 114 is located circularly on the periphery of the pivotal connection means 11.
  • a cylindrical coupling device 12 is extended from the pivotal connection means 11.
  • a rod 121 is extended from the coupling device 12.
  • the rod 121 has a smaller diameter than the coupling device 12.
  • a hole 122 is formed on the rod 121.
  • the lower arm 20 has a disk-shaped pivotal connection means 21 having a shaft hole 211 on the center corresponding to the shaft 111 of the upper arm 10.
  • a rib 212 is located on the pivotal connection means 21 beside the shaft hole 211.
  • a cylindrical coupling device 22 is extended from the pivotal connection means 21.
  • a rod 221 is extended from the coupling device 22.
  • the rod 221 has a smaller diameter than the coupling device 22.
  • a hole 222 is formed on the rod 221.
  • the upper arm 10 is coupled with the lower arm 20 by pivotally coupling the pivotal connection means 11 with the pivotal connection means 21, wherein the shaft 111 of the pivotal connection means 11 is inserted into the shaft hole 211 of the pivotal connection means 21, and wherein the projecting flange 114 of the pivotal connection means 11 is wedged in the inner wall of the pivotal connection means 21.
  • the upper and lower arms 10 and 20 can be positioned by the projecting lug 113 and the rib 212 that is able to block each other to prevent rotation.
  • these two arms 10 and 20 including the pivotal connection means 11 and 21 can be securely screwed or riveted together by inserting a screw or a rivet into the through hole 112, and thus the assembling process of the present invention is completed.
  • the coupling devices 12 and 22 of the upper and lower arms 10 and 20 are rotated to allow the rotation of the shaft 111 in the shaft hole 211 and the rotation of the projecting flange 114 of the pivotal connection means 11 along the inner wall of the pivotal connection means 21.
  • the pivotal connection means 11 and 21 are rotated 90 degrees from each other, the projecting lug 113 of the pivotal connection means 11 is blocked by the rib 212 of the pivotal connection means 21, and thus the purpose of positioning the arms 10 and 20 is achieved.
  • rods 30 are fixedly connected to the coupling devices 12 of the upper arms 10 and the coupling devices 22 of the lower arms 20 via first ends thereof, and screwed or riveted thereon by inserting screws or rivets into the holes 122 of the coupling devices 12 and the holes 222 or the coupling devices 22.
  • the rods 30 are coupled with rotation shafts 40 or foldable devices 50 via second ends thereof.
  • a complete guardrail structure is formed.
  • the rods 30 are detached from the rotation shafts 40 first.
  • the pivotal connection means 11 and 21 of the upper and lower arms 10 and 20 including the rods 30 screwed or riveted thereon are rotated toward each other to separate the projecting lugs 113 from the ribs 212 such that the inclined angle between the upper arm 10 and lower arm 20 is less than 90 degrees.
  • the rods 30 can be arranged parallel to each other by using the foldable devices 50 coupled therebetween. As a result, the size of the guardrail structure can be reduced to provide the convenience of storing the guardrail structure.
  • the guardrail joint structure is composed of the upper and lower arms, wherein the guardrail joint structure is rotatable and positionable by using the pivotal connection means that pivotally couple with each other, the corresponding shaft and shaft hole, and the projecting lug and rib that baffle each other. As a result, the convenience of using and storing the guardrail structure is increased.
  • the present invention indeed achieves the expected objects by disclosing a guardrail joint structure that is convenient to carry and easy to use. Accordingly, the present invention meets the requirement for patentability and is therefore submitted for a patent.
