Doors have in the past been used for mounting a variety of exercise devices. Exemplary of such mountings are:
Pollock U.S. Pat. No. 5,254,065 issued Oct. 19, 1993 entitled Flexible Loop Fastening Strap Supportable in Door Structure. In this disclosure, a strap having an enlarged end portion is trapped on one side of the door with a loop depending to the opposite side of the door. The loop acts as the anchored point from which a portion of an exercise device may be attached.
McFall et al. U.S. Pat. No. 5,468,205 issued Nov. 21, 1995 entitled Portable Door Mounted Exercise Apparatus. In this disclosure, two large pulley assemblies are mounted to the top and bottom of a door. The pulley assemblies have elastic members connecting the top pulley assembly to the bottom pulley assembly. The disclosed pulleys have relative large diameters and are canted out of the plane of the door so that they may swivel about an axis tilted toward the person utilizing the exercise device.
Weintraub U.S. Pat. No. 5,601,518 issued Feb. 11, 1997 entitled Portable Exercise Device. In this disclosure, top and bottom U-shaped brackets mount to a door to suspend an otherwise elaborate exercise device. Upper brackets and pulleys together with a lower lever produce a large essentially not portable exercise device.
Mazor U.S. Pat. No. 6,059,698 issued May 9, 2000 entitled Exercise Device for Removable Mounting on a Door. In this disclosure, top and bottom U-shaped brackets form anchor points for exercise devices.
I have discovered that such door-mounted devices suffer from at least two deficiencies. First, most devices mount relatively large mechanical structures to the door in the form of pulleys, levers, top and/or bottom mounted (typically U-shaped) brackets. These large mechanical structures subtract from the exercise device's portability, which is the principle reason for mounting the device to a door in the first place. Secondly, and most importantly, all these devices locally strain the door edges, usually at the top or the bottom of the door. These local strains on the door edges render device mounting damaging to the door and can produce hazardous conditions.
In the following specification, I will refer to the structure of a door. As most are aware, a door closes between two doorjambs with a lintel extending across the door top. Typically, the door is mounted by hinges at one doorjamb and swings to and from positions of engagement of a lock set to the other doorjamb. I describe a door having a closing face and an opening face. The closing face of the door closes into the doorframe consisting of the doorjambs and lintel. The opening face of the door opens out and away from the doorframe. This terminology will be used in the specification and claims that follow.
In what follows, I solve this deficiency by first constructing a strap deadman which optimally strains a door by tension only into the door's jambs and lintels so that a vertically disposed strap on a face of the door can act as the deadman point of attachment. Secondly, I disclose a deadman having a plurality of attachment points. The resulting deadman cooperates with simple strain producing members—such as elastic tubes—which enable floor to ceiling anchor points enabling a full exercise vocabulary adaptable to any prescribed fitness regimen.
A door-mounted strap extends around a door in the vertical direction, from the top of the door to the bottom of the door to act as a deadman preferably toward an exerciser on the closing side of the door. The strap is continuous as it faces the exerciser. On the rear side of the door, away from the exerciser, the strap has a tension-locking clamp, typically a ladder lock, enabling the tightened strap to snugly surround the door. A back-mounting strip exceeds in width and underlies the door-mounted strap at least on the side of the door disposed towards the exerciser. This back-mounting strip is sewn at intervals to enclose the horizontally disposed linear back members of D-rings at approximate 10-inch intervals. The back mounted strip typically terminates at the upper lintel of the doorframe with a thickened section to prevent circumferential excursion of the door-mounted strap relative to the door. Removable attachment elastic members for fastening to the arcuate portions of the D-rings are provided in combination with handholds, limb straps, and the like to enable standing, sitting and/or prone exercise positions. All members of the exercise device are tensile members, which can collapse for complete portability.
An advantage of the disclosed deadman is that it cooperates with the doorjambs and lintels to impart all strain on a distributed basis from the door to the building structure. As a result, the door acts as a plate urged on a unitary basis into the surrounding building structure where distribution of exercise induced strain is distributed at the door periphery into the surrounding building structure.

The construction of strap 3 is easily understood. Referring to
Unless unrestrained it would be possible for strap 3 to rotate as it is fastened around door 2. Forming an enlarged section in the strapping surrounding door 2 can prevent this. An example of this is shown in
It will be understood that many exercises when attached to the respective D-rings will tend to cause the strap 3 and the backing strap 31 to undertake circumferential excursion relative to the door D. Thickened section 34 will resist such excursion. Specifically, when an exerciser undertakes exercise either as set forth in
It will be understood that strap 3 is fastened to door 2 when door 2 is in the opening position. Typically the strap 3 passes over closing face 21 of door 2, around the bottom of the door, and back over the top of the door. Backing strap 32 only extends under strap 3 at one door face. In the view of
Referring to
Observing
Once strap 3 is in place, elastic exercise gear 4 is passed through D-rings 33. Elastic exercise gear 4 is typically comprised of elastic tubing. It will be understood that other elastic tensile members can just as easily be used. For example bungee cords, tensioning coil springs, and the like can as well be used. Further it will be understood that more than one elastic exercise gear 4 can be passed through one or more of the individual D-rings. In this way tension may be varied depending upon the particular exercise undertaken as well as the particular individual involved.
Each of the elastic exercise gear 4 has clips 41 attached to either of the ends. These respective clips 41 can be attached to handholds 42 or to limb bands 43.
For example, referring to

It will be understood that this invention can easily be utilized as a portable kit. The components of such a portable kit are all illustrated in FIG. 7. These components include the door mounting strap 3, waistband W, individual hand holds 41, enlarged hand hold 42, limb band 45, arm bands 46, elastic arrays 4, and finally a carrying case 50. It will be understood by the expedient of taking carrying case 50 loaded with the displayed contents of
This invention relates to a door attached deadman for an exercise devices. Specifically, a door mounted vertical strap cooperating with the door jambs and lintel is disclosed for providing any room with a door as a candidate location for wall mounted exercise devices. This application claims priority from Provisional Patent Application 60/357,365 filed Feb. 15, 2002 entitled Door Mounted Deadman for Exercise Devices.
