Patent number: 8132787Abstract: Conical jack stands that are used to hold up a motor vehicle (or other object) after it has been raised (e.g., by jacks). Rather than having legs like conventional jack stands, they have the shape of a hollow cone, with a circular bottom edge. The circular bottom edge gives them a larger bottom surface area than the bottom ends of the legs of conventional jack stands, so that they will be less likely to sink into the ground or asphalt. There is a hole with internal screw threads in the top of each cone, into which a large bolt-like contacting member is screwed. The contacting members can be rotated to adjust the height of the jack stands. Their hollow conical shape makes it easy to stack the jack stands for storage. Four jack stands are stored in a square box, with one contacting member in each corner of the box.Type: GrantFiled: April 1, 2009Date of Patent: March 13, 2012Inventor: Robert Douglas Audet

Publication number: 20080203367Abstract: In an elevating device for raising and lowering a heavy member by rotating a rotation axis extending in a direction crossing a vertical direction, the rotation axis has one end portion to which the heavy member is connected. The rotation axis includes a bendable portion adapted to transmit a rotational force. A leading end portion of the free end portion is vertically suspended from the bendable portion of the rotation axis regardless of a stop position of the rotation axis. A rotation applied by the heavy member to the rotation axis is suppressed by the suspended leading end portion. With such an elevating device, unexpected rotation of the rotation axis is positively suppressed in a cost-effective manner.Type: ApplicationFiled: March 4, 2008Publication date: August 28, 2008Applicant: TOKYO ELECTRON LIMITEDInventor: Kengo Ashizawa

Publication number: 20080197329Abstract: A safety nut (220) received slidingly in a seat (205) through which a threaded bar (203) passes, is coupled with front inter-locking (209B, 220A) with the lifting nut (209); release occurs when wear of the thread of the lifting nut (209) exceeds a safety limit; an axial stop formed of a bearing (228) rests on the safety nut (220) to support the load mechanically interrupting movement. A warning switch (250) is activated by the safety nut before said mechanical shut-down.Type: ApplicationFiled: June 7, 2006Publication date: August 21, 2008Inventor: Natale Brechelente

Patent number: 7410201Abstract: An improved lead screw actuator for use in applications including power vehicle windows is provided that significantly reduces the amount of machining that must be performed on the lead screw to enable secure attachment of a gear or pulley. The lead screw has a plurality of threads on its outer annular surface and a first and second axially spaced circumferential groove. A gear or pulley disposed about the lead screw has a female thread formed into an inner annular surface that is configured to engage at least one of the plurality of threads of the lead screw between the first and second grooves. A pair of rings are disposed within the first and second grooves in order to restrict axial movement of the gear or pulley on the lead screw.Type: GrantFiled: October 29, 2004Date of Patent: August 12, 2008Assignee: Dana Automotive Systems Group, LLCInventors: Daryl Wilson, Scott L.

Patent number: 7383922Abstract: A load stopping system for mechanically stopping a load in a relatively slow and controlled manner using rotational and frictional forces. The system includes a glide rod, a guide collar that moves longitudinally over the glide rod, two vertically mounted friction rods mounted on opposite sides of the glide rod, a friction collar that moves longitudinally along each friction rod, and a support platform coupled to each friction collar and to the guide collar. The glide rod includes a spiral fluted vane along its entire length upon which the guide collar rides when a force is placed on the support platform. The friction rod and collars use friction to control the movement of the support platform along the direction of travel.Type: GrantFiled: June 12, 2006Date of Patent: June 10, 2008Inventors: William H. Richey, John Bolding

Patent number: 7344117Abstract: An adjustable lift support apparatus includes a base, a sleeve attached onto the base, at least one meshing device, a shaft, and a support attached at the shaft. At least one groove is formed on an inner surface of the sleeve along a first axial direction. Each meshing device corresponds to one of the at least one groove and includes a flexible protrusion. The shaft is inserted into the sleeve. At least one rack is provided on an outer surface of the shaft along a second axial direction, such that the flexible protrusion of the meshing device is meshed between two neighboring teeth of the at least one rack. The support is lifted or lowered by an external force to make each of the at least one rack move with respect to the flexible protrusion of the corresponding meshing device, so as to adjust the height of the support.Type: GrantFiled: December 30, 2005Date of Patent: March 18, 2008Assignee: Benq CorporationInventor: Wei-Shin She

Publication number: 20070278465Abstract: The invention relates to a hoisting device (1), in particular for a vehicle, including a substantially vertical column forming a frame and lifting means movable along said column under the action of the control, by adequate driving means, to cause a threaded rod (2) to rotate and a nut (3) integral with a carriage (4) bearing the load (20) to be lifted to move along the latter. It is characterized in that this nut (3) is a catch nut, which comprises a first bearing nut (5) on which said carriage (4) rests, and a second safety nut (6) coaxial to the preceding one and placed below same, designed capable of receiving and bearing the load formed by said carriage (4) and its load (20) and by said first bearing nut (5) in the event of failure of the latter.Type: ApplicationFiled: May 30, 2007Publication date: December 6, 2007Applicant: SEFAC SOCIETE ANONYMEInventor: Eric LETELLIER

Patent number: 7207548Abstract: An automobile jack stand having four sides that substantially form a pyramid. Extending from the pyramid is a telecopying support. The telescoping support is attached to a curved horizontal support arm which is the primary point for support. Extending outward from two sides are small support arms which are equipped with light sockets. The light sockets rotate from a horizontal position to a vertical position. The lights are connected to a battery located in the base of the jack and the battery is connected to a electrical cord capable of connecting to an electrical out. The electrical cord functions to recharge the battery.Type: GrantFiled: May 16, 2006Date of Patent: April 24, 2007Inventor: Richard L. Howe
