Definitions
- the invention relates to a bed side rail, comprising two side bars with a rotational bearing at the bottom end for attachment to the bed, connected by a top bar at the top to form a parallelogram, with a locking mechanism fitted between one of the side bars and the top bar.
- side rails are used to prevent a patient from falling out of a bed.
- a patient is prevented from falling off the bed's mattress either by several side rails operating together or by a single side rail taking up most of the side of the mattress area.
- these types of side rails are not fixed to the bed rigidly, but in such a way that they can be lowered to allow the patient to get out of bed or to allow medical personnel access to the patient and easier manipulation.
- Tubular side rails are generally attached to the bed using two rotational pins, and sometimes the locking device is a part of one of these pins.
- the locking device is a part of one of these pins.
- Utility model CZ 16127 shows a similar tubular side rail.
- a combination of two buttons serves as the locking mechanism of the side rail.
- the side rail is unlocked.
- the disadvantage of this solution is the unsuitable position of the entire locking mechanism in relation to the operation of the bed, as the side rail lock is located on the pin attaching the side rail to the bed.
- Another disadvantage is the need to operate the lock using fingers, which is not as simple or fast as using the entire hand.
- the operator is forced to manipulate the side rail using both hands, as in the case of the solution based on patent US 7,073,219.
- Patent application US2012023666 shows another locking mechanism.
- an actuator in the form of a button which when pressed causes the movement of the locking member against a spring by virtue of pressure force to unlock the side rail.
- the disadvantage of this solution is in the force of the members of the locking mechanism, where enormous friction occurs between the button and locking element, which may cause a malfunction of the mechanism or unnatural movement of the button.
- JP2009213797 shows another mechanism for a folding side rail.
- the locking mechanism of the side rail consists of a lever rotating around an axis to which a blocking element is connected via a system of brackets. When the lever is raised, this causes the movement of the blocking element and a shift of the blocking pin. Following the rotational movement of the lever, the side rail bar is released as the blocking element and blocking pin are unblocked.
- the solution in this invention has the disadvantage of an excessively complicated mechanism and low level of robustness, due to which the solution is prone to failures.
- a bed side rail comprising two side bars with a rotational bearing at the bottom end for attachment to the bed, connected by a top bar at the top to form a parallelogram, with a locking mechanism fitted between one of the side bars and the top bar, the essence of which, according to the invention, lies in the fact that the locking mechanism comprises a rotational member firmly fixed to the side bar and a covering member firmly fixed to the top bar, where these members are connected to each other by a common axis.
- the side rail moves, there is mutual rotation of both members around this axis. This rotational movement is limited by a latch.
- the side rail of the bed based on this invention improves operator comfort and patient safety.
- the blocking member is rotationally positioned in the top bar and pushed into the blocking position by a blocking spring.
- the movement of the latch is controlled by an actuating member, which is rotationally located in the top bar.
- side rail includes at least one auxiliary bar which is located between the side bars below the top bar and which is rotationally connected to the side bars.
- a torsion spring is located in the rotational bearing of at least one side bar.
- Fig. 1 shows the bed side rail based on the invention.
- Fig. 2 and 3 show a detail of the locking mechanism in various positions.
- Fig. 4 shows a detail of the rotational bearing of the side bar with the torsion spring.
- Fig. 1 shows the side rail 2 of a hospital bed, which has two tubular side bars 5.
- the side bars 5 are connected together by a tubular top bar 6 at the top end to form a parallelogram, and the locking mechanism 3 is fitted between one of the side bars 5 and the top bar 6.
- Two auxiliary bars 7 are fitted between the side bars 5 below the top bar 6, which are pivotally connected to the side bars 5 at both ends.
- Fig. 2 shows the locking mechanism 3 comprising two members.
- the rotational member 11 is firmly fixed to the side bar 5 and the cover member 12 is firmly fixed to the top bar 6. These members have a rotational part consisting of circular profiles with a common axis of rotation 10.
- the rotational member 11 is located inside the cover member 12, along with the locking mechanism.
- the cover member 12 includes the stop 13.
- the rotational member 11 may be firmly fixed to the top bar 6, and the cover member 12 may be firmly fixed to the side bar 5, in the same way as the movement of the cover member 12 in relation to the rotational member 11 may be alternatively blocked by the stop 13.
- the side bars 5 have a rotational bearing 4 at the bottom end for attachment to the bed frame 1.
- a torsion spring 19 which is fixed through the side bar 5 at one end, and the other end is fixed to the bed frame 1 via the anchor of the spring 18.
- the anchor of the spring 18 remains in one position during the movement of the side rail, and does not rotate as it is firmly attached to the bed frame 1 via the spring case 20, first flange 21 and second flange 22.
- the first flange 21 and second flange 22 are either welded to the spring case 20, or make up a single integrated component with the spring case 20, so that they do not move in relation to each other.
- the second case 23 During movement of the side rail, the second case 23 remains fixed in position in relation to the side bar 5 as it is attached to it with a friction washer 24, which engages with the latch in the side bar 5.
- the torsion spring 19 is fitted in such a way that in the raised position of the side rail 2 it acts in one direction with a smaller torque and in the lowered position of the side rail 2 it acts in the other direction with a greater torque. This results in the torsion spring 19 causing a downward movement of the unlocked side rail in the raised position and inhibition of this movement in the lowered position, because the torque is reversed during the movement of the torsion spring 19.
- the latch 9 is located in the cover member 12. In the raised position of the side rail, the latch 9 rests on the recess 15 and prevents the rotational movement of the rotational member 11 relative to the cover member 12. The movement of latch 9 is limited by the spring 14, which is also located in the cover member 12 and acts against the latch 9 on first end through torque. At the second end, the spring 14 is locked by a pin. Pressing the actuating member 8 leads to its axial rotation and contact between the actuating member 8 and the latch 9 results in axial rotation of latch 9. When the rotational member 11 is rotated relative to the cover member 12 along the common axis of rotation 10, the side rail 2 drops down and the latch 9 contacts the rotational member 11 from the side and is forced against it by the spring 14. When the side rail 2 is raised again, it is automatically locked in position.
- Recess 15 is shaped so as to prevent the spontaneous slipping of the latch 9 from this recess. Additionally the recess 15 can be designed to copy the shape of the latch 9.
- the procedure is reversed.
- the torsion spring 19 reduces the force necessary to lift the side rail 2.
- Staff use their hand to raise the top bar 6, and at the same time the stop 13 starts to move away from the first notch 16 towards the second notch 17 and before they come into contact, the spring 14 moves the latch 9 against the recess 15, and the side rail is locked in position.
