  • Publication number: 20170282661
    Abstract: A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.

  • Patent number: 9700679
    Abstract: The drive mechanism for a drug delivery device comprises a piston rod, which is displaced in a distal direction for a delivery of a dose and in a proximal direction for a reset, and a resilient member, which acts on the piston rod during a reset and tends to restrict the movement of the piston rod in the proximal direction. The resilient member may be a biasing member provided for an automatic reset, a compression spring entering the piston rod or a torsion spring provided to generate a rotation. The drug delivery device is provided with such a drive mechanism.

  • Patent number: 9675760
    Abstract: The drive mechanism for a drug delivery device comprises a piston rod, which is displaced in a distal direction for a delivery of a dose and in a proximal direction for a reset, and a rotatable drive member, which is threadedly engaged with the piston rod and rotates during the delivery of the dose. A biasing member is provided, which is loaded by the rotation of the drive member during the delivery of the dose and tends to rotate the piston rod with respect to the drive member in such a way that the piston rod is screwed into the drive member and is thereby advanced in the proximal direction. The drug delivery device is provided with such a drive mechanism.

  • Patent number: RE46814
    Abstract: A medication delivery device is provided which is switchable between an operational state and a resetting state and which comprises a housing having a proximal end and a distal end, a piston rod being moveable in a distal direction with respect to the housing for medication delivery, a conversion element adapted to at least partially convert a rotational movement of the piston rod into an axial movement of the piston rod, coupling means prevented from rotational movement with respect to the housing and adapted to engage with the conversion element in the operational state, a drive assembly comprising at least two drive assembly members and adapted for moving the piston rod in the distal direction, and a resilient member adapted to provide a force on the drive assembly for engagement of the drive assembly members. In the operational state of the device the coupling means is engaged with the conversion element, the conversion element thereby being prevented from rotation with respect to the housing.
