This document relates to a rowing handle. Rowing machines utilize a rope, chain, and/or pulley that connect to a rowing handle to facilitate the rowing movement. A user pulls the rowing handle as part of the rowing movement. Generally, the rowing handle has two grip portions on opposing sides of the handle that enable a user to grip the opposing sides of the handle using two hands.
In general, one innovative aspect of the subject matter described in this specification can be embodied in a rowing handle including a grip portion and two members that are formed or attached on opposite sides of the grip portion relative to a center of the grip portion, each member having a hook shape, and where the hook shape of a first member is formed in a first direction relative to a grip axis defined by the grip portion and the hook shape of the second member is formed in a second opposite direction than the hook shape of the first member.
In some implementations, the first member includes a first arm portion that extends away from the grip axis defined by the grip portion and a first engagement portion that is formed along a first engagement axis that intersects a first arm axis defined by the first arm portion.
In some implementations, the first member has a first return portion that is formed along a first return axis that is substantially parallel to the first arm axis defined by the first arm portion.
In some implementations, the second member includes a second arm portion that extends away from the grip axis defined by the grip portion and is formed in a first member plane that is substantially parallel to a second member plane that is defined by the first member and a second engagement portion that is formed along a second engagement axis that intersects a second arm axis defined by the second arm portion.
In some implementations, the second member has a second return portion that is formed along a second return axis that is substantially parallel to the second arm axis defined by the second arm portion.
In some implementations, the first arm portion and the second arm portion extend away from the grip axis at different angles.
In some implementations, the two members are formed to fit in holes defined in a rowing machine handle of a rowing machine. In some implementations, the two members are formed to engage grip portions on opposite sides of a rowing machine handle of a rowing machine.
In some implementations, the hook shape of each member is an L-shape or a C-shape. In some implementations, the cross-sectional shape of each member is a D-shape.
In some implementations, a rowing handle includes a grip portion and two members, including a first member and a second member, that are formed or attached on opposite sides of the grip portion relative to a center of the grip portion and each member having a hook shape, where the hook shape of the first member is formed in a same direction as the hook shape of the second member. Other implementations can include corresponding methods.
Particular embodiments of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages. The rowing handle described herein (also referred to as an adaptive rowing handle) can be attached to various different rowing machine handles or directly attached to the rowing machine (e.g., a rope or chain of the rowing machine). The adaptive rowing handle allows for one-handed use of the rowing machines, which enables users who may have use of only a single-hand or arm to row with a single hand or arm more effectively and/or conveniently than is possible with the traditional rower handle, which is configured for rowing with two hands or arms. The adaptive rowing handle also enables users who prefer single-handed use (e.g., to isolate a single arm or side of the body during workouts) to row with a single hand. Additionally, the adaptive rowing handle can be used in combination with an already installed rowing machine handle, for example, by attaching to the already installed rowing machine handle. The adaptive rowing handle can be attached to the already installed rowing machine handle in a manner that enables the rowing to be performed with either one hand using the adaptive rowing handle or two hands using the already installed rowing handle without having to remove the rowing handle described herein. Thus, if two athletes are taking turns rowing during a workout (e.g., during a partner style workout), one of the athletes can use the adaptive rowing handle, while another athlete can use the traditional rowing handle without having to remove the adaptive rowing handle. In some implementations, the adaptive rowing handle includes a locking mechanism that secures the rowing machine handle to a portion of the traditional rowing handle, chain or rope of the rowing machine, or another portion of the rowing machine when it is not being used.
The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.
Like reference symbols in the various drawings indicate like elements.
This document describes devices and methods for a rowing handle that attaches to a rowing machine or traditional rowing handle to enable single-handed operation of a rowing machine by a user.
In some implementations, grip portion 102 may include a grip pad 108 formed or attached to grip portion 102 (e.g., attached with adhesive or screws). Grip pad 108 may be formed from a same material as the grip portion 102, or of a different material (e.g., foam, rubber, or another material). Grip portion 102 and/or grip pad 108 may include texture (e.g., non-slip hash marks), indentations (e.g., demarcations for hand/finger positions), or can be smooth.
Two members 110 and 112 are formed or attached to grip portion 102. The members 110 and 112 are formed on opposing sides of the grip portion 102 relative to the center point 106 of the grip portion 102. Note that the exact location of the members 110 and 112 relative to the center point 106 can vary. Typically, the members 110 and 112 will be separated enough so that the grip portion 102 that is between the members 110 and 112 can be gripped by a hand. Members 110 and 112 can be formed or attached flush with or separated from respective ends of the grip portion 102 (e.g., the members can be formed at a location that is inset from respective ends of the grip portion 102). Members 110 and 112 may be formed of a same or different material as grip portion 102. For example, members 110 and 112 can be formed of lightweight aluminum and the grip portion 102 is formed of plastic with a grip pad 108 made of foam (or another material). Alternatively, the members 110 and 112, as well as the grip portion 102 can all be formed of plastic, rubber, a composite, or another material.
Member 110 is formed in a plane 114 that intersects and/or is perpendicular to axis 104 (as seen, for example, in
The arm portion 118 is attached to, formed on, or otherwise engaged with the grip portion 102 and extends away from the grip axis 104 defined by the grip portion 102. The axis defined by a length of the arm portion 118 is referred to as a first arm axis 120. The engagement portion 122 is formed along a first engagement axis 124, and the first engagement axis 124 intersects the first arm axis 120 defined by the arm portion 118. The engagement portion 122 can be formed at an end of the arm portion 118 (e.g., a distal end of the arm portion 118 relative to the grip portion 102) or another location along the arm portion 118.
In some implementations, member 110 includes a return portion 126 formed along a first return axis 128 that is substantially parallel to the first arm axis 120. The return portion 126 can be formed at an end of the engagement portion 122 (e.g., a distal end of the engagement portion relative to the arm portion 118) or another location along the engagement portion 122.
Member 112 is formed in a second member plane 130 that intersects and/or is perpendicular to axis 104 (as seen, for example, in
The plane 130 can be parallel to the first member plane 114 defined by the first member 110, but is not required to be parallel. The hook shape of member 112 can be formed in an opposite direction relative to the direction in which the hook shape of member 110 is formed. For example, as shown in
The member 112 can be formed/configured in a similar manner as described above with reference to member 110. For example, as shown, member 112 includes an arm portion 134 that is attached to, formed to, or otherwise engages the grip portion 102 and extends away from the grip axis 104 of the grip portion 102. The arm portion 134 defines a second arm axis 136 that intersects and/or is perpendicular to the grip axis 104. Like member 110, member 112 includes an engagement portion 138 that is formed along a second engagement axis 140 that is defined by the engagement portion 138, and which intersects with a second arm axis 136 defined by the arm portion 134. The engagement portion 138 can be formed at an end of the arm portion 134 (e.g., a distal end of the arm portion 134 relative to the grip portion 102) or another location along the arm portion 134.
Member 112 can also include a return portion 142 formed along a second return axis 144. In some implementations, the second return axis 144 can be substantially parallel to the second arm axis 136, but it could have a different angle relative to the second arm axis 136 defined by arm portion 134. The return portion 142 can be formed at an end of the engagement portion 138 (e.g., a distal end of the engagement portion relative to the arm portion 118) or another location along the engagement portion 138.
In some implementations, members 110, 112, and grip portion 102 have a circular cross-sectional shape 146 (e.g., a cross sectional slice taken perpendicular to the first return axis 128), as shown in
In some implementations, arm portion 118 of member 110 and arm portion 134 of member 112 extend away from the grip axis 104 at different angles (e.g., angles 152 and 154). For example, angles 152 and 154 are of a same magnitude but are inverses of each other relative to axis 150 (e.g., +/−17.5 degrees, respectively). In some implementations, angles 152 and 154 are of different magnitudes.
In some implementations, an acuteness of curvature of the hook shape of a member, for example member 110, depends in part on length 156 between the arm portion 118 in first arm axis 120 and the return portion 126 in the second return axis 128. For example, for a shorter length 156, the hook shape of member 110 would define a smaller hook than the hook defined for a longer length 156.
In some implementations, the length 156 may be selected based on dimensions of a rowing machine handle 200 with which the rowing handle 100 will be used.
In some implementations, members 110 and 112 are formed to fit in holes 204 and 206 defined in the traditional rowing machine handle 200 of a rowing machine. For example, hole 204 has particular dimensions defining a perimeter of an opening and an area through which portions of the member 110 can pass, and hole 206 has particular dimensions defining a perimeter of an opening and an area through which portions of the member 112 can pass. Thus, the members 110 and 112 can be inserted through the holes 204 and 206 respectively, thereby securing the adaptive rowing handle 100 to the traditional rowing machine handle 200.
In some implementations, member 110, including attachment portion 112 and return portion 126 passes through hole 204. In order for portions of member 110 to pass through hole 204, dimensions of a cross-sectional area 146 of portions of member 110 must be small enough to fit within the dimensions of hole 204. For example, for a cross-sectional area 146, where the area is a circle in shape, a diameter of the cross-sectional area 146 may be smaller than a smallest dimension (e.g., a width) of the hole 204.
In some implementations, rowing handle 100 may be affixed to or installed on traditional rowing machine handle 200 single-handedly by a user. For example, a user holding grip portion 102 can rotate about an axis 208 substantially perpendicular to axis 104 along the length of grip portion 102. The user can rotate the rowing handle 100 such that the return portion 126 and the attachment portion 122 pass through hole 204 of the rowing machine handle 200. The user can then rotate about the axis 208 in an opposite direction such that the return portion 126 and the attachment portion 122 passes through hole 204 of the rowing machine handle 200. The user can then level the adaptive rowing handle 100 such that axis 104 through the length of the grip portion 102 of the adaptive rowing handle 100 is substantially parallel to axis 210 through the length of the traditional rowing machine handle 200.
A user may then utilize adaptive rowing handle 100 affixed to traditional rowing machine handle 200 to utilize a rowing machine with a single hand (e.g., perform a rowing motion using a single hand). For example, a user may hold grip portion 102 in one hand and pull in a direction of motion of the rowing machine (e.g., along axis 208).
In some implementations, a length 212 of space between members 110 and 112 along the length of the grip portion 102 is selected based on the spacing between holes 204 and 206. For example, the length 212 can be selected so that the members 110 and 112 will engage specified holes in the traditional rowing machine handle 200. Alternatively, the length 212 can be selected so that the engagement portions 122 and 138 will engage a portion of the traditional rowing machine handle 200 is typically held by a user. For example, the length 212 can be selected so that the engagement portions 122 and 138 are engaged with portions of the traditional rowing machine handle 200 that are closer to the ends of the handle 200 (e.g., wrap around the exterior of the handle 200).
In some implementations, members 110 and 112 are formed to engage grip portions 214 and 216 of the traditional rowing machine handle 200 where the grip portions 214 and 216 are on opposite sides of the traditional rowing machine handle 200 of a rowing machine relative to a central axis 208 of the traditional rowing machine handle 200. For example, adaptive rowing handle 100 has member 110 which engages with grip portion 216 of the traditional rowing handle 200 through hole 204, and member 112 which engages with grip portion 214 of the traditional rowing handle 200 through hole 206.
In some implementations, the two members 502 and 504 can be formed to fit in holes defined in the traditional rowing machine handle of a rowing machine, as described above with reference to
In some implementations, the rowing handle 500 can include engagement portions and return portions similar to those discussed above with reference to
Two members are formed or attached on opposite sides of the grip portion relative to a center of the grip portion (604). For example, members 110 and 112 are formed/attached on grip portion 102. The two members can each be made of the same or a different material relative to the material used to form the grip portion. Member 110 is formed in a first member plane 114 and member 112 is formed in a second member plane 130. In some implementations, the first member plane is substantially parallel to the second member plane, but the first member plane and the second member plane need not be substantially parallel in all implementations.
Each member is formed having a hook shape. In some implementations, the hook shape of a first member is formed or attached in a first direction relative to a grip axis defined by the grip portion, and the hook shape of a second member is formed or attached in a second, opposite direction relative to a grip axis defined by the grip portion. For example, with reference to
In some implementations, forming a first member includes forming a first arm portion extending away from the grip axis defined by the grip portion and a first engagement portion in a first engagement axis intersecting a first arm axis defined by the first arm portion. For example, member 110 is formed by an arm portion 118 in a first arm axis 120 and an engagement portion 122 in a first engagement axis 124.
In some implementations, forming the first member includes forming the first member such that the first member has a first return portion formed on a first return axis, where the first return axis is substantially parallel to the first arm axis. For example, a first return portion 126 is formed on a first return axis 128, which is substantially parallel to first arm axis 120. Note that the first return axis is not required to be parallel to the first arm axis, and a variety of angles relative to the first arm axis are contemplated.
In some implementations, forming a second member includes forming a second arm portion extending away from the grip axis defined by the grip portion and a second engagement portion in a second engagement axis intersecting a second arm axis defined by the second arm portion. For example, member 112 is formed by a second arm portion 134 in a second arm axis 136 and an engagement portion 138 in a second engagement axis 140.
In some implementations, forming the second member includes forming the second member such that the second member has a second return portion formed on a second return axis, where the second return axis is substantially parallel to the second arm axis. For example, a second return portion 142 is formed on a second return axis 144, which is substantially parallel to second arm axis 136. Note that the second return axis is not required to be parallel to the second arm axis, and a variety of angles relative to the second arm axis are contemplated.
In some implementations, forming the first arm portion of the first member and the second arm portion of the second member includes forming the first arm portion and the second arm portions at different angles relative to the grip axis defined by the formed grip portion. For example, first arm portion 118 of member 110 in the first arm axis 120 is formed at an angle 152 relative to an axis 150 defined perpendicular to the grip axis 104, and the second arm portion 134 of member 112 in the second arm axis 136 is formed at an angle 154 relative to axis 150. In some implementations, the first arm portion and the second arm portion are formed at a same angle relative to the grip axis (e.g., when the hook shape of the first member and the second member are formed in a same direction).
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
