Patent number: 8296880Abstract: A hammock having a self-closing bottom entrance slit is constructed with the slit substantially offset to one side of the center line of the hammock. This improves comfort by enabling one to lie in the hammock out of contact with the slit, and facilitates the addition of an insulating panel to the hammock.Type: GrantFiled: May 15, 2007Date of Patent: October 30, 2012Assignee: Hennessy Holdings, Ltd.Inventor: Thomas F.

Patent number: 7243383Abstract: A system of tripods, bipods and/or unipods is used to support a polygonal array of horizontal spars joined by connector hubs. The array may be extended indefinitely, in order to support a desired number of hammocks. As few as three different stock components are required. Each hammock is suspended from the structure by connecting its ends to a pair of the connector hubs.Type: GrantFiled: February 24, 2006Date of Patent: July 17, 2007Assignee: Hennessy Holdings, Ltd.Inventor: Thomas F. Hennessy

Patent number: 6421851Abstract: A hammock includes a bed made of a rectangular piece of fabric, whose ends are gathered together and secured to ropes which can be tied to respective trees. A ridge cord extends between the gathered ends, this cord being shorter than the fabric bed, so that the bed sags somewhat no matter how much tension is applied to the ropes. An entrance slit extending about half the length of the hammock allows one to enter from below. The hammock has a lozenge shape when it is viewed from the top and may be covered by a lozenge-shaped canopy.Type: GrantFiled: January 29, 2001Date of Patent: July 23, 2002Inventor: Thomas F. Hennessy

Patent number: 5016455Abstract: A cylinder lock system employing a key having a projection extending from each opposing parallel edge of the key blade, the projections respectively operating an auxiliary pin tumbler stack and cooperating with a groove in the lock shell to retain the key in the lock after plug rotation from the key insertion position. The key retaining projection also cooperates with the driver pin of the auxiliary pin tumbler stack to prevent key trapping, i.e., the presence and size of the retaining projections keeps the auxiliary driver pin from engaging the keyway. The cooperation between the key retaining projection and the auxiliary driver pin is permitted by providing the lock with two shear lines, located on different diameters, which are simultaneously operable by a single key.Type: GrantFiled: June 8, 1990Date of Patent: May 21, 1991Assignee: Lori CorporationInventor: Thomas F. Hennessy

Patent number: 4823575Abstract: A cylinder lock system employs a key which has a pair of projections extending from opposing parallel edges of the key blade. The keyway of the lock has an enlarged slot portion for receiving the projections upon insertion of the key. One of the projections cams pins of an auxiliary pin stack to present a shear line between the pins to permit rotation of the key plug to an unlocked mode. The other projection is received in a groove formed in the shell and is engageable against a surface of the groove upon rotation of the key to retain the key within the keyway.Type: GrantFiled: September 28, 1987Date of Patent: April 25, 1989Assignee: Bauer Kaba AGInventors: David W. Florian, Thomas F. Hennessy

Patent number: 4779909Abstract: A latch actuator mechanism (10) having a housing (18) in which is mounted a lever (40 ) that engages a carrier member (54) that surrounds a spindle (66). The spindle includes a radial projection (74) that engages a recess (60) in the carrier member (54) such that as the lever (40) is pivoted, it linearly displaces the carrier member which in turn bears upon the projection (74) to rotate the spindle (66). The spindle is connected to a latch (16) that extends transversely to the axis of the spindle and is actuated for engagement and disengagement to strike (82). The preferred latch mechanism includes an elongated latch case (88) mounted transversely on the spindle (66), the latch having a retractor member (96) mounted for linear displacement longitudinally within the case and a latch bolt head (114) adapted for a projected and a withdrawn position relative to the case.Type: GrantFiled: January 15, 1987Date of Patent: October 25, 1988Assignee: Lori CorporationInventor: Thomas F. Hennessy

Patent number: 4524593Abstract: A compact cylinder lock operated by a key having smooth edges and detents in opposed side faces. The locking mechanism includes series connected pin tumblers and side bars which are resiliently biased. A resiliently biased locking bar having locking lugs extending therefrom cooperates with the side bars and lock housing; the locking bar moving out of engagement with the housing and into gates in the side bars when the side bars are moved a sufficient distance by the pin tumblers. The side bars are provided with false gates which engage the lugs on the locking bar to prevent unauthorized opening of the lock.Type: GrantFiled: July 5, 1983Date of Patent: June 25, 1985Assignee: Lori CorporationInventor: Thomas F. Hennessy

Patent number: 4484463Abstract: A guard for protecting the cylinder of a door lock from removal comprises a substantially rectangular plate having a first portion including a section adapted to fit over the lock cylinder and a second portion offset from the first portion, the second portion traversing the gap between the door and the doorjamb for protecting the bolt.Type: GrantFiled: September 27, 1982Date of Patent: November 27, 1984Assignee: Lori CorporationInventor: Thomas F. Hennessy

Patent number: 4404824Abstract: A compact cylinder lock operated by a key having smooth edges and detents in opposed side faces. The locking mechanism includes series connected pin tumblers and side bars which are resiliently biased. A resiliently biased fence cooperates with the side bars and lock housing; the fence moving out of engagement with the housing and into gates in the side bars when the side bars are moved a sufficient distance by the pin tumblers.Type: GrantFiled: February 5, 1981Date of Patent: September 20, 1983Assignee: Lori CorporationInventor: Thomas F. Hennessy

Patent number: 4272974Abstract: A key operated dead bolt lock includes one or a pair of standard threaded mortise cylinders. The lock further includes set screws, inaccessible from either side of a door in which the lock is installed, which prevent rotation of the cylinders. The cylinders hold cylinder collars in place to prevent access to the bolt from the side.Type: GrantFiled: January 25, 1979Date of Patent: June 16, 1981Assignee: Lori Engineering CorporationInventor: Thomas F. Hennessy
