Description

  The present invention relates to the field of hanging rail systems for patient lifts. In particular, the present invention relates to a system for enabling the safe transfer of a patient lift carriage between two hanging rails.

  A patient lift mounted on a suspended rail system is for lifting, lowering and moving a person who needs assistance such as lifting, lowering and moving, such as a patient, an elderly person or a disabled person. Usually used as support. The patient lift is typically coupled to a carriage that is mounted on the rail of a suspended rail system. Such a suspended rail system is non-movable and is, for example, attached to the ceiling, a primary rail, suspended from the primary rail and movable relative to the primary rail. One or more secondary rails. It may be necessary to move the patient lift from one secondary rail to another, or between the secondary and fixed rails, or between any two rails. This type of transfer may be accomplished by positioning the ends of the two rails and then sliding the carriage from one rail to the other. However, during normal operation, the rail preferably has stop means to prevent the patient lift carriage from accidentally leaving the rail. In order to avoid wasting time in manual removal of the stop means in the transfer state, a mechanism has been proposed for automatically releasing the stop means to enable transfer.

  One such mechanism, called "Transition gate", is provided by Prism Medical. The “transition gate” includes a rod-like stop member that extends to a rail near its end. The stop member is movable at right angles to the length direction of the rail and can either prevent or enable movement of the carriage via the rail. The wheel member is connected to each stop member at a right angle. The wheel is configured to interact with the guide so that the stop member is lifted. Transfer of the patient lift carriage between the two rails is possible only at a specific position where the guide is attached to the primary rail. In this position, the wheel attached to the stop member of the first rail is engaged with the guide attached to the primary rail, and the wheel attached to the stop member of the second rail is the first rail. Engage with the guide attached to the. Thereby, the two stop members are lifted and can be transferred. One problem with such a mechanism may be that the two secondary rails need to be moved to a predetermined position where the guide is attached to the primary rail to allow transfer. Another problem is that the carriage can accidentally leave one of the rails, thereby causing an accident, because the other rail is not positioned end to end. This is because, for example, the stop member may be lifted when the rail is positioned such that the stop member wheel is engaged with the guide, which is attached to the primary rail.

Each rail extends along the length of the rail so that the cart may move or be mounted in the rail, for example, having a portable patient lift or motor device coupled to it. There are slits on the bottom of the rails. The first rail 1 has an end face 3, and the second rail 2 has an end face 4. In FIG. 1, the rails are not aligned with each other or are not placed in positions where the ends face each other, ie the end faces 3, 4 do not face each other.

  A first engaging member 5 is attached on the top of the first rail 1, and a third engaging member 6 is attached on the top of the second rail 2. The first engagement member 5 and the second engagement member 6 have a T-shaped cross section when viewed from above, and the rails 1 and 2 are arranged at positions where the end portions face each other. It has flat front surfaces 5a, 6a that are sometimes formed to face each other. The flat front surfaces 5a, 6a are perpendicular to the direction of rail extension. The T-shaped cross-section is selected to ensure the possibility of stable attachment to the rail, and its shape may be selected in any suitable way, as realized by those skilled in the art. The engaging members 5 and 6 have grooves 5b and 6b cut into the front surfaces 5a and 6a, respectively. The grooves 5b, 6b have Gaussian elongated portions, and start and end at either side of the respective engagement members 5, 6. The groove has a rectangular cross section with a depth of about one third of the width. The groove 6b has a larger rising portion than the groove 5b.

  Each of the first engagement member and the second engagement member further includes longitudinal grooves 5c and 6c cut into the front surfaces 5a and 6a. The vertical grooves 5c and 6c are deeper than the Gaussian grooves 5b and 6b, and the lower portions of the front surfaces 5a and 6a are left uncut, and the first engaging member and the first grooves Extends partially along the height of the two engagement members.

  The 1st stop member 7 is arrange | positioned so that a movement is possible through the hole of the top part of the 1st rail 1 in the vertical groove 5c. The 2nd stop member 8 is arrange | positioned so that a movement is possible through the hole of the top part of the 2nd rail 2 in the vertical groove 6c.

The front surfaces 15a and 16a are perpendicular to the extending direction of the rail. The T-shaped cross-section is selected to ensure the possibility of stable attachment to the rail, and its shape may be selected in any suitable way, as realized by those skilled in the art. The engaging members 15 and 16 have grooves 15b and 16b cut into the front surfaces 15a and 16a, respectively. Grooves 15b and 16b have Gaussian extensions and start and end on either side of each engagement member 15 and 16, respectively. The groove has a rectangular cross section with a depth of about one third of the width. The groove 16b has the same shape as the groove 15b, and the grooves are biased in a direction perpendicular to each other. Thus, the groove 16b is biased at a higher position than the groove portion 15b.

  Each of the first engagement member and the second engagement member further includes longitudinal grooves 15c and 16c cut into the front surfaces 15a and 16a. The longitudinal grooves 15c and 16c are deeper than the Gaussian grooves 15b and 16b, and the lower portions of the front surfaces 15a and 16a are left uncut, and the first engaging member and the second Extends partially along the height of the engagement member.

  The 1st stop member 17 is arrange | positioned so that a movement is possible through the hole of the top part of the 1st rail 11 in the vertical groove 15c. The 2nd stop member 18 is arrange | positioned so that a movement is possible through the hole of the top part of the 2nd rail 12 in the vertical groove 16c. The stop member is thus arranged to move essentially perpendicular to the rail. When the first stop member 17 and the second stop member 18 are not arranged so that the end faces the end portion of the rail, the first stop member and the second stop member are arranged at the height of the rail. Up to about 50% of the length of the corresponding rail. Each of the first stop member 17 and the second stop member 18 has a cylindrical main body. Each of the second engagement member 19 and the fourth engagement member 110 includes a wheel portion that is attached to one of the stop members 17 and 18 at a right angle via a shaft portion. The second engagement member 19 and the fourth engagement member 110 face away from the front surfaces 15a and 16a of the first engagement member and the second engagement member and face in opposite directions. The shaft portion is supported by lower portions of the vertical grooves 15c and 16c.

  The stop members 17, 18 remain in this blocking position by gravity unless the rails are arranged with the ends facing each other.

  FIG. 5 shows the same embodiment of the suspended rail system as in FIG. In FIG. 5, the rails are aligned with each other or in a position where the ends face each other, that is, the end faces 13, 14 face each other. The wheel portions of the second engagement portion 19 and the fourth engagement portion 110 are moved in advance in the grooves until reaching the position shown in the drawing, that is, the highest position of each of the grooves 15b and 16b. Ascend to the position. Since the stop members 17, 18 are coupled to the second and fourth engagement members, the stop members are also in the raised position and do not extend into the rails 11, 12. Thereby, both rails 11 and 12 are not obstructed, and the carriage can be transferred or transferred from the first rail to the second rail, or vice versa. The vertical displacement between the grooves 15b and 16b prevents the second engaging member and the fourth engaging member from colliding with each other.

  FIG. 6 shows the same embodiment of the suspended rail system as in FIGS. In FIG. 6, the rails are no longer aligned with each other or in an end-to-end position. The end faces 13, 14 partially overlap or face each other, but are not sufficiently aligned to allow transfer or transition. The wheel portion reaches the middle of the grooves 15b and 16b. Thus, the stop members 17, 18 are in a partially raised position, but extend sufficiently into the rails 11, 12 to prevent the carriage from accidentally leaving any of the rails.
