Slide extractor braking system
Embodiments of the present disclosure relate generally to improved braking systems for slide extractors. Slide extractors are generally used in aircraft galleys in order to move containers forward. The disclosed slide extractor braking system provides cooperation between magnets and corresponding conductive material in order to manage and appropriately slow retraction of the slide extractor in use.
1. A system for slowing movement of a slide extractor used in an aircraft galley for moving one or more containers and/or trolleys forward within a storage area, the system comprising:
a slide base comprising a channel;
a movable member positioned within the channel and slidable with respect to the slide base;
a retraction element associated with the movable member; and
one or more magnets associated with either the slide base or the movable member;
and wherein the other of the slide base or the movable member comprises at least a portion of a conductive surface,
wherein proximity of the one or more magnets to the portion of a conductive surface causes slowing of the movable member with respect to the slide base.
2. The system of claim 1 , wherein the one or more magnets is positioned within an internal channel of the slide base.
3. The system of claim 2 , wherein at least a first portion of the one or more magnets are positioned in a first rail portion of the slide base and wherein at least a second portion of the one or more magnets are positioned in a second rail portion.
4. The system of claim 1 , wherein at least a portion of the slide base is manufactured of a polymeric material.
5. The system of claim 4 , further comprising one or more wear strips positioned at slide base rail edges where the moveable member slides with respect thereto.
6. The system of claim 1 , wherein the at least a portion of a conductive surface is positioned on a sliding portion of the movable member.
7. The system of claim 6 , wherein the movable member further comprises a polymeric flange.
8. The system of claim 6 , wherein the movable member further comprises a polymeric end cap.
9. The system of claim 1 , further comprising a handle secured to at least one end of the retraction element.
10. The system of claim 9 , wherein the handle comprises two symmetrical parts configured to cooperate with one another.
11. The system of claim 9 , wherein the retraction element is secured within the handle via an abutment member.
12. The system of claim 1 , wherein the moveable member comprises a pinion wheel and wherein the slide base comprises a toothed rack.
13. The system of claim 1 , further comprising a pulley system configured to coordinate movement of the moveable member within the slide base.
14. The system of claim 13 , wherein the pulley system comprises a wheel secured to the movable member and a pulley plate to which a portion of the pulley is secured.
