20220032113
The present disclosure relates generally to an exercise device, more specifically a door mount exercise device.
Home exercise devices that mount in a doorway for doing chin-up, pullup, dips and other exercises are available. Typically, these exercise devices are bulky and difficult to store, and fail to provide parallel chin up bars for neutral grip chin-ups. Often user of these devices can be in small homes or apartments where space is at a premium and they would like to be able to take down the exercise device and have it ‘disappear’ and take up as little space as possible for easy storage.
Therefore, there is a need for a door mount exercise device that can provide parallel chin-up bars and is able be stored in a small space.
In accordance with the teachings of the present disclosure, a foldable exercise device is provided that has a chin-up exercise apparatus and a dip exercise apparatus suspendable from the chin-up exercise apparatus. The chin-up exercise apparatus has a top horizontal member and a bottom horizontal member connected by two connecting members.
Each connecting member has a door header hook and a parallel chin-up handle that rotate on the connecting member from a flat configuration to an exercise configuration. The door header hook and parallel chin-up handle are on opposite sides of the two connecting members. In the exercise configuration the chin-up exercise apparatus can releasably engage a door frame with the bottom horizontal member contacting the front side of the door frame by pressing against the vertical door jams of the door frame and the door header hook can engaging with the back side of the door by contacting a door frame header. In the exercise configuration the parallel chin-up handles can be used to do neutral chin-ups.
The dip exercise apparatus is suspendable from the chin-up exercise apparatus. The dip exercise apparatus has two vertical members, where each vertical member has a top end and a bottom end. The top end is configured to suspend the dip exercise apparatus from the chin-up exercise apparatus. The bottom end has a bottom grip, where the bottom grip can be rotated from a flat configuration to an exercise configuration. The two vertical members are spaced apart at a predefined distance by a horizontal connecting member. In the exercise configuration the bottom grips are substantially perpendicular to the two vertical members and the horizontal connecting member and when suspended from the chin-up exercise apparatus can be used to do dip exercises. In the flat configuration the bottom grips and the horizontal connecting member are substantially parallel.
Rotation of the door header hook may cause rotation of the parallel chin-up handle.
The connecting member is straight with a round cross section and there is a sleeve that is around the connecting member, where the door header hook and the parallel chin-up handle are attached to the sleeve.
The foldable exercise device may further include a chin-up bar biasing mechanism, where the chin-up bar biasing mechanism biases the parallel chin-up handle into the exercise configuration. The chin-up bar biasing mechanism may include a sleeve that is around the connecting member, and the door header hook and the parallel chin-up handle are attached to the sleeve, where the connecting member is a tube with a circular cross section, the tube has an axis and there is a slot in the tube running parallel to the axis in which passes a first pin that is perpendicular to the axis of the connecting member. The first pin extends beyond the connecting member. Pushing on the first pin is a spring that is inside the connecting member. The first pin pushes on the sleeve, the other end of the sleeve is pushing against a second pin that goes through the connecting member. The sleeve has a detent for the second pin to move into that biases the sleeve to the exercise configuration.
The horizontal connecting member may be foldable.
The foldable exercise device may also include a bottom grip biasing mechanism that biases the bottom grip to the exercise configuration. The bottom grip biasing mechanism may include a sleeve that is around the vertical members and the rotatable handle is attached to the sleeve. The vertical member is a tube with a circular cross section and there is a slot in the tube running parallel to the axis in which passes a pushing pin that is perpendicular to the axis of the vertical member. The pushing pin extends beyond the vertical member. Pushing on the pushing pin is a spring that is inside the vertical member. The pushing pin pushes the sleeve, the other end of the sleeve is pushing against a retaining pin that goes through the vertical member. The sleeve has a detent for the retaining pin to move into that biases the sleeve to the exercise configuration.
Additional features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.
The top horizontal member 110 may be straight or contoured with various bends (for example as shown) to allow for more grip options for doing exercises and thus enable a user to exercise slightly different muscles. The top horizontal member 110 may have foam cushioning 150 at various places, for example on the outer most part or in the middle, spaced shoulder-width apart. The foam cushioning provides comfort and grip when grasping during exercises. The top horizontal member 110 should be wide enough to span most door openings, for example 39 inches long.
The connecting member 120 is shown with a sleeve 155, a door header hook and a parallel chin-up handle 130. The connecting member 120 is straight with a round cross section and the sleeve 155 is around the connecting member 120. The door header hook 125 is attached to the connecting member via the sleeve 155, and the door header hook 125 extends away from the connecting member 120. The parallel chin-up handle 130 is also attached to the connecting member via the sleeve 155 and is shown extending away from the connecting member 120 in the direction opposite the door header hook 125. The door header hook 125 and the parallel chin-up handle 130 may rotate on the connecting member 120 via the sleeve 155.
In the exercise configuration, the door header hooks 125 and the parallel chin-up handles 130 are roughly perpendicular to the bottom horizontal member 115. The chin-up apparatus 100 can be releasably engaged with a door frame, for example the door header hooks 125 can be engaged with the back side of a door frame header 140. The door header hooks 125 can be in any number of shapes that allow the door header hooks 125 to securely hold to the back side of the door frame header 140. For example, the engagement part of the door header hook may be hooked over the top lip of the frame, or the door header hook may just press up against the frame. The bottom horizontal member 115 can press against the front of vertical door jams 135. The bottom horizontal member 115 may press directly against the vertical door jams 135 or press through frame protectors 145. Frame protectors 145 may allow the force to be distributed over a larger area and may allow for more grip to help prevent the chin-up apparatus 100 from slipping down. When weight is applied to the top horizontal member, like a user suspending themselves, the device will provide the counter balance to the force with a torque to keep the top horizontal member 110 stationary with the door header hook 125 pulling back because of the force coming from the back of the top frame and the bottom horizontal member 115 pushing forward with the pressure from the front of the vertical door jams 135. The friction and possible the top hook being over the lip of the top frame can ensure that the chin-up apparatus 100 remain sturdily attached to the door frame, especially with the extra weight when being used for exercise.
With the chin-up apparatus 100 engaged with a door frame a user can do neutral chin-ups using the parallel chin-up handles 130 that can extend away from the door frame parallel to each other. The parallel chin-up handles 130 may have foam cushioning. A user can also support themselves from the top horizontal member 110 to do various exercises like chin-ups, pull ups of various width and other exercises.
Transitioning between the exercise configuration and the flat configuration may be a matter of the door header hook 125 and the parallel chin-up handle 130 transitioning from being in a plane perpendicular to the bottom horizontal member 115 to being co-planer with the bottom horizontal member 115. The door header hook 125 and the parallel chin-up handle 130 may rotate around the connecting member 120. The sleeve 155 is shown as a single piece and the door header hook 125 and the parallel chin-up handle 130 are shown rigidly attached such that rotation of the door header hook 125 also causes the chin parallel chin-up handle 130 to rotate. Although the door header hooks 125 and the parallel chin-up handle 130 are shown rigidly attached other configurations are possible that allow them to rotate independent of each other, for example by having two sleeves 155 on the connecting member 120, where one for the parallel chin-up handle 130 and one from the door header hook. Another example may be the chin-up handles being able to rotate 270 degrees before contacting the door header hook 125 so that it starts rotating. As shown the parallel chin-up handle 130 may rotate to the inside between the connecting members 120 and the door header hook 125 may rotate to the outside. In an alternative configuration the door header hook 125 may rotate to the inside between the connecting members 120 and the parallel chin-up handles 130 may rotate to the outside. If the door header hooks 125 and the parallel chin-up handles 130 are not rigidly attached, they could even rotate to the same side of the connecting member 120 and thus allow other configurations and lengths not constrained to the space between the connecting members 120.
The chin-up apparatus 100 may have a biasing mechanism that helps put and keep chin-up apparatus 100in the exercise configuration. In addition, the biasing mechanism may help put and keep the chin-up apparatus 100in the flat configuration. For example, the biasing mechanism may help hold the door header hook 125 and the parallel chin-up handle 130 in the perpendicular position by requiring extra force to move out of the perpendicular position. In addition, when close to the perpendicular position the biasing mechanism may help move the door header hook 125 and the parallel chin-up handle 130 into to the perpendicular position. Similarly, the biasing mechanism may have a second bias for the parallel chin-up handle 130 and he door header hook 125 to be coplanar with the bottom horizontal member 115 for the flat configuration.
The vertical member 405 has a top end 420 and a bottom end 425. The top ends 420 may have a hook shape or other shape that enables the dip exercise apparatus 400 to be suspended from a support, for example the support may be a horizontal rod, like the bottom horizontal member 115 or the top horizontal member 110 of the chin-up apparatus 100. The top ends 420 may have the hooks oriented so they are aligned so they can hook over a single rod, as shown, or the hooks could be oriented another direction for example facing each other to attach to the parallel chin-up handle 130, the connecting member 120 or the sleeve 155 when in the chin-up apparatus 100 is in the exercise configuration. The hooks maybe configured such that=the hooks can attach to any support that can enable the dip exercise apparatus 400 to be suspended to be used for exercise.
The vertical member 405 has a bottom end 425 shown with a bottom grip 430 in the exercise configuration. Supporting the bottom grip 430 is a diagonal support 435 that connects on an angle from the top of a bottom sleeve 440 to the rear of the bottom grip 430. In the exercise configuration, the bottom grip 430 is substantially perpendicular to the plane containing the two vertical members 405. The bottom grips 430 may be used to do dip exercises, inverted body weight row exercises, leg raises, inverse level and other exercises.
The bottom end 425 may rotate on the vertical member 405, for example the bottom sleeve 440 may rotate around the axis of the vertical member 405. Alternatively, the bottom end 425 may lack the diagonal support 435 and the bottom grips 430 may attach to the vertical member 405 via a horizontal bolt and flip up to be more aligned to the vertical member 405, and in some configurations flip up and be parallel to the vertical member 405.
The dip exercise apparatus 400 may transition between the exercise configuration and the flat configuration. In the exercise configuration the bottom handle 430 is in a perpendicular position where the bottom handle 430 is perpendicular to the plane containing the vertical members 405. In the flat configuration the bottom grip 430 is no longer perpendicular to the plane but rather in an aligned position. In the aligned position the bottom grip 430 is oriented to have the dip exercise apparatus 400 be flatter, for example the bottom grip 430 may be aligned to the horizontal connecting member 410 or co-planer with the two vertical members 405.
The dip exercise apparatus 400 may have a biasing mechanism to bias the bottom grips 430 into the perpendicular position, and possibly also into the flat configuration. If the bottom end 425 rotates around the axis of the vertical member 405 then the biasing mechanism may be like the biasing mechanism 300 described for the parallel chin-up handles. The biasing mechanism may bias the bottom grip to the perpendicular position for the exercise configuration of the dip exercise apparatus. The biasing mechanism may bias the bottom grips into the aligned position.
In the double flat configuration, the horizontal connecting member 410 is folded in half at the joint 450 as shown with the axis of the joint 450 being parallel to the vertical members 405. When folded the two halves of the horizontal connecting member 410 may touch back to back and the vertical members are separated by the two halves of the horizontal connecting member 410. Alternatively, the two halves may hinge to bring the two vertical members together. If the connection between the horizontal connecting member 410 and the vertical member 405 is allowed to pivot, then the vertical members 405 could be rotate to align being roughly parallel and provides a long skinny orientation with hooks on the end that can be easily stored.
Alternately the horizontal connecting member 410 could ‘fold-up’ if joint 450 has a hinge axis that is perpendicular to the plane containing the two vertical members 405. In the fold-up double flat configuration if the connection between the horizontal member and the vertical member is allowed to pivot the fold-up double flat configuration may be long and skinny with the vertical members and the halves of the horizontal member being roughly parallel or generally aligned. If the fold-up configuration the joint 450 may have a latch to keep the horizontal connecting member 410 straight. This may be particularly useful if the joint 450 is a hinge that opens downward toward the ground.
