Abstract

The towable pulling member for baggage includes a pulling handle that can be turned two-dimensionally with respect to the arm portion of the pulling member and can be locked at a plurality of positions. Due to the pivotal relationship between the tow handle and the arm portion, when the user pulls the baggage, the handle can be rotated to a position where the tow handle can be gripped at a comfortable position on the side of his / her body. Further, this turning relationship improves the operability of the baggage by reducing the need to twist his / her wrist when the user changes the direction of the towable baggage. The present invention allows the traction handle of the retractable traction member to pivot to an appropriate position with respect to the baggage, so that the traction handle is flush with the baggage and is not caught by other objects.

1. TECHNICAL FIELD The present invention relates to the field of travel luggage that can be towed by hand. More particularly, the present invention relates to a traction member having a traction handle, wherein the traction handle is pivotally attached to an arm portion of the traction member and can be locked at a plurality of positions. The pivotal connection between the traction handle of the traction member and the arm portion allows the user to hold the traction handle in a more comfortable position than otherwise possible when towing the baggage on a flat surface.

2. 2. Description of Related Art A wide variety of baggage is usually provided with one or more wheels so that a person can pull them while traveling. Typically, a towable baggage also includes a tow member with an arm portion that connects a towable handle to the baggage. The length of the arm portion connecting the towable handle to the baggage prevents the baggage from contacting the user's legs and feet when towing the baggage.

Even baggage that is not permanently equipped with wheels or towing members can be towed using a tow cart. If a typical cart is removably secured to the baggage, wheels and tow members for towing the baggage can be provided.

Whether the traction member is an integral part of the baggage or a part of the traction cart, the majority of traction members have a traction handle that can be selectively extended and retracted from the towed baggage. Due to the function of extending and retracting the tow member, the tow member does not get in the way when not towing baggage. In addition, when the traction member is in the retracted position, baggage can easily be accommodated in the trunk of the car or in the overhead compartment of the airplane during travel.

If the wheel and towable member of the towable baggage are permanently secured to the baggage, the wheeled baggage comprises an extendable tow member comprising a pair of parallel telescopic poles bridged by a tow handle. However, the telescopic pole is slid into a separate vertical tubular outlet fixed to the interior compartment of the baggage. Nested traction members consisting of a single pole extending and retracting from a single tubular outlet located in the middle of the baggage wheel are also known and used. In any case, baggage with a permanently secured traction member typically has a traction handle outlet that, when retracted, is identical to the outer surface of the baggage. It will be in the plane. This prevents the traction handle from getting in the way when the baggage is not being pulled, making it difficult for the traction handle to be caught by other objects, while improving the appearance of the baggage.

More common with tow carts, but other types of baggage use non-nestable stretchable tow members such as bars and poles that are hinged to rotate against the baggage There is. Typically, these hinged traction members include some type of clasp that holds the traction member on the side of the bag when not towing the bag, and this clasp is The traction member can be released and swung upward to the extended position.

Regardless of the type of traction member, the traction member that can be extended normally includes a mechanism that locks the traction member in the extended position. Such locking mechanisms are well known in the art and include instruments such as spring-loaded detents, cam locks, and other interference locks. Some lock mechanisms are unlocked by manually operating the release mechanism. Other locking mechanisms, such as many spring-loaded detent mechanisms, are automatically released by simply applying sufficient force to the traction handle to retract the detent. Furthermore, some traction members include a lock mechanism that can lock the traction member in the retracted position.

Despite the convenience of being able to tow baggage instead of traveling with it while traveling, towing baggage can be an inconvenient and cumbersome task. One of the reasons that pulling baggage can be cumbersome is the location and shape of the pull handle of most pull members. As described above, the traction handle of the two-pole traction member is usually a bridge that bridges and connects the poles. Accordingly, such tow handles are generally oriented horizontally with respect to the plane that pulls the baggage and extend perpendicular to the path that pulls the baggage. In this configuration, the user generally has to hold the traction handle behind the body with the wrist rotated in either direction to almost the limit of rotation. Towing such baggage over long distances can be painful in this posture, and often feels the need to change the handle once or several times to avoid fatigue.

Despite the comfort disadvantages of the tow handle configuration described above, achieving alternate orientations of these tow handles often requires sacrificing other aspects related to the utility of these devices. For example, if the handle of the extendable traction member is shaped to make it more comfortable, when the traction member is retracted, the handle must protrude from the baggage or the handle insertion port must be enlarged. High nature. Another drawback associated with the towing handle having the above-described configuration is that the gripping form for holding the towing handle may make it difficult to twist the wrist any more, thereby limiting the operability of the towed luggage. It is a point.

The towing member of the present invention is configured to be used in combination with towable baggage. According to the invention, the traction member comprises a traction handle that is attached to the arm portion of the traction member so that it can pivot about at least one axis, and in some embodiments can be locked in multiple positions. It is.

The relative movement between the traction handle of the traction member and the arm portion allows the traction handle to be held in a comfortable position when the user pulls the baggage. Furthermore, the relative movement between the traction handle of the traction member and the arm portion eliminates the need for the user to adjust the grip of the traction handle when attempting to change the direction of the baggage, thereby improving the operability of the baggage. Furthermore, the relative movement between the traction handle and the arm portion allows the traction handle to be repositioned when retracting the arm portion, so that it does not interfere with the use of baggage.

In general, the traction member of the present invention includes an arm portion and a traction handle. The arm portion is configured to connect the traction handle to the baggage, and the traction handle is connected to the arm portion in a manner that allows the traction handle to pivot relative to the arm portion. In a first embodiment of the invention, the arm portion uses a telescoping member consisting of a single curved pole that is selectively extended from or pulled into the baggage. The pulling handle of the first embodiment has a T-shaped shape, and the turning mechanism can turn the handle about the central axis of the arm portion defined by the entire length of the arm portion.

By allowing the traction handle to pivot about the central axis of the arm portion, the traction handle of the first embodiment can be pivoted, and the horizontal bar, that is, the handle is directed upward, and the baggage can be loaded using the traction member. Stretching behind the towing user. Therefore, unlike the traction member in which the handle is oriented horizontally and laterally, the traction handle of the first embodiment can be gripped with the user placing his / her hand on the side of the body and the palm facing the waist. . Therefore, the tow handle of the first embodiment can be gripped in a natural and comfortable manner as when carrying the briefcase. Tilt upwards and behind the handle increases comfort because the user can keep the wrist in the middle of its range of motion. Furthermore, the pivoting relative movement between the tow handle and the arm portion reduces the need for the user to twist his / her wrist when towing the baggage.

The traction member of the first embodiment is adapted to be permanently secured to the baggage and preferably includes a slot for receiving the traction handle therein when retraction of the traction handle is desired. Tow handle so that the handle is oriented horizontally and laterally when retracted (generally desirable to accommodate the tow handle because of the preferred arrangement of the tow member adjacent to the baggage outer surface) Can be turned.

In a second embodiment of the invention, the arm portion has a length with a proximal end and a distal end opposite to each other, the proximal end of the arm portion being operably secured to the baggage. ing. The traction handle of the second embodiment is operably secured to the distal end of the arm portion and allows a pivoting movement of the traction handle relative to the arm portion about at least two pivot axes. Since the traction handle of the second embodiment of the traction member can pivot about at least two pivot axes with respect to the arm portion, the second embodiment of the traction member provides all the advantages described above with respect to the first embodiment. However, it is also an improvement of the first embodiment.

In the third embodiment of the present invention, the traction member includes a traction handle, an arm portion operably connected to the traction handle, a turning mechanism, and a lock mechanism. The arm portion is constructed and adapted to secure the tow handle to the baggage. When the tow handle is fixed to the baggage through the arm part, the tow handle is pivotable about a part of the arm part that is separated from the baggage and located outside the baggage centering around the pivot axis. The pivot mechanism connects the tow handle to the arm portion. The lock mechanism is operably coupled to the traction handle and the arm portion, and is selectively movable between a lock position and an unlock position with respect to the arm position. When the lock mechanism is in the locked position, it restricts turning of the traction handle around the pivot axis with respect to the part of the arm portion, but when in the unlocked position, the lock mechanism is centered on the pivot axis with respect to the arm portion. The turning of the tow handle is not restricted.

In a fourth embodiment, the arm portion has a length with a proximal end and a distal end opposite to each other, and the proximal end of the arm portion is operably secured to the baggage. The traction handle of the fourth embodiment is operably fixed to the distal end of the arm portion, and allows the traction handle to pivot with respect to the arm portion about at least two pivot axes. including. The locking mechanism is operably connected to the traction handle and the arm portion. Furthermore, the lock mechanism is selectively movable between a lock position and an unlock position with respect to the arm portion. When locked, the locking mechanism prohibits movement in the two axes. When unlocked, the locking mechanism releases movement on at least one axis, but preferably releases movement on both axes. The locking mechanism releases the components of the arm portion so that they can be telescoped together.

While the main advantages and features of the present invention have been described above, the invention can be understood and appreciated more fully and in detail with reference to the following drawings and detailed description of the preferred embodiments.

The first embodiment of the traction member of the present invention is particularly adapted and configured to be an integral part of the baggage. As shown in FIGS. 1 and 2, the traction member (20) of the first embodiment is attached to a wheeled backpack (22), and includes an arm portion (24), a traction handle (26), and a turning mechanism.

Thus, the two tubular members (110) of the arm portion (102) function in much the same way as a conventional single pole member, so that these two members replace the single tubular member primarily for aesthetic purposes. It is used. Finally, a through hole (112) is preferably formed through each tubular member at a location adjacent to the distal edge (114) of each tubular member (110).

The arm portion (102) also includes a pair of distal end caps (116), preferably made of a polymeric material. Each end cap (116) includes a base (118) configured and adapted to be socketed into the distal end of one tubular member (110). A shoulder (120) is formed on each end cap (116) adjacent to the base (118) and abuts the distal edge (114) of each tubular member (110) such that the end cap is a tubular member. It is prevented from being inserted further inside. A first through hole (122) is formed through each base (118) of the end cap (116). When the base of the end cap is inserted into the tubular member (110) and the shoulder (120) of the end cap abuts the distal edge (114) of the tubular member, the through hole (122) of each base corresponds Aligned with the through hole (112) of the tubular member. A rivet-like fastener (124) extends through the through-hole (112) of each tubular member (110) and the first through-hole (122) of the base (118) of each end cap, thus tying the end cap. It is fixed to the tubular member.

Each end cap (116) further includes a planar support surface (126) oriented orthogonally to its shoulder (120). The support surface (126) preferably comprises a circular outer periphery. A second through hole (128) is formed through each end cap and is located in the center of the support surface and orthogonal to the support surface. The second through holes (128) of the support cap are coaxial with each other. The second through hole includes a counterbore (130) formed on the opposite side of the support surface (126) in each end cap (116). The counterbore (130) thus forms a recessed annular shelf (132). As described above, with each end cap (116) attached to one tubular member (110) of the arm portion (102), the end cap support surfaces (126) are spaced apart, parallel, and Opposite.

The traction handle (104) of the second embodiment of the traction member (100) is preferably made from a polymeric material and a metal.

The base (138) of the traction handle (104) is also preferably made of a polymeric material and integrally formed with the grip (134). The base (138) intersects the grip (134) and extends from the grip, preferably orthogonally. A circular support surface (140) is formed at the end of the base (138) of the traction handle. The traction handle (104) is preferably a metal handle pivot shaft (142) located at the center of the base support surface (140) and projecting orthogonally from the support surface. (142). The pivot shaft (142) projects from the support surface of the base to a threaded portion (144) near the distal end of the shaft. The opposite end (146) of the handle pivot shaft (142) extends into the handle grip (134) and is preferably thinned, knurled, or otherwise textured. Preferably, the grip part (134) and the base part (138) of the traction handle (104) are formed around the handle pivot shaft, and the handle pivot shaft is formed on the grip part and base part of the traction handle. Fix it.

The intermediate member (106) of the traction member (100) is preferably made from a polymeric material as a single seamless part. A pair of first and second circular support surfaces (146), (148) are formed at opposite ends of the intermediate member (106) and are parallel and aligned with each other. A third circular support surface (150) is formed in the intermediate member (106) and is oriented orthogonally to the first and second circular support surfaces (146), (148). A first through hole (152) passes through the intermediate member (106) perpendicularly from the center of the first support surface (146) to the center of the second support surface (148). A second through hole (154) passes through the intermediate member (106) perpendicularly from the center of the third support surface (150). The second through hole (154) includes a counterbore (156) formed in the intermediate member (106) from the opposite side of the third support surface (150). The counterbore (156) forms a recessed annular shelf (158).

In addition to the arm portion (102), the traction handle (104), and the intermediate member (106), the traction member (100) of the second embodiment is stepped used to integrally connect the components of the traction member. Includes a bolt (160), a stepped bolt nut (162), and a handle pivot shaft nut (164). The traction handle (104) is assembled to the arm portion (102) of the traction member (100) via the intermediate member (106).

In assembling various components of the traction member (100) of the second embodiment, first, the handle pivot shaft (142) of the traction handle (104) is inserted into the second through hole (154) of the intermediate member (106). Thus, the support surface (140) of the traction handle is brought into contact with the third support surface (150) of the intermediate member. Next, the handle pivot shaft nut (164) is inserted into the central lumen (156) of the intermediate member (106) and the nut (164) is gently abutted against the recessed annular shelf (158) of the intermediate member. Screwed into the threaded portion (144) of the pivot shaft (142). The handle pivot shaft nut (164) then holds the support surface (140) of the traction handle (104) against the third support surface (150) of the intermediate member (106). The handle pivot shaft nut (164) is preferably a self-locking nut, and in the assembled state, the traction handle (104) and the handle pivot shaft nut are in the second through hole (154) of the intermediate member (106). It is preferable to use a washer (not shown) so as to rotate freely integrally with the intermediate member without requiring excessive torque and without loosening the nut around the shaft. The handle pivot shaft (142) and handle pivot shaft nut (164) of the traction handle (104) are dimensioned so as not to obstruct the first through hole (152) of the intermediate member (106).

When the traction handle (104) is assembled to the intermediate member (106) as described above, the intermediate member is then armed to the traction member (100) using the stepped bolt (160) and the stepped bolt nut (162). It is assembled to the part. To perform this assembly, first the first and second support surfaces (146), (148) of the intermediate member (106) are placed between the support surfaces (126) of the end cap (116) of the arm portion (102). And the first through hole (152) of the intermediate member is aligned with the second through hole (128) of each end cap. Next, the stepped bolt (160) is inserted into the end hole (130) of one end cap (116), and the second through hole (128) of each end cap and the intermediate member are inserted into the stepped bolt. The first through hole (152) of (106) is penetrated. Next, the stepped bolt nut (162) is inserted into the counterbore (130) of the other end cap (116) and screwed into the stepped bolt (160). Similar to the handle pivot shaft nut (164), the stepped bolt nut (162) is preferably a self-locking nut. When the stepped bolt nut (162) is tightened to the stepped bolt (160), the stepped bolt and the stepped bolt nut come into contact with the recessed annular shelf (132) of the end cap (116), and these end portions Pull the caps together. The dimension of the intermediate member (106) is such that there is some interference fit between the first and second support surfaces (146), (148) of the intermediate member and the support surface (126) of the end cap (116). Decide to do. Tightening the stepped bolt nut (162) to the stepped bolt (160) is only necessary to eliminate the gap between the end cap (116) and the intermediate member (106). It should be understood that the cap cannot be tightened to such an extent that the pivoting motion about the stepped bolt shaft is largely hindered.

When the traction member (100) of the second embodiment is assembled as described above, the traction handle (104) can pivot about two axes with respect to the arm portion (102) of the traction member. The first axis is a stepped bolt (the center of which the traction handle (104) and intermediate member (106) pivot about the end cap (116) of the arm portion (102) of the traction member (100). 160). This first axis remains substantially parallel to the axis of rotation of the baggage wheel to which the traction member (100) is finally attached. The second axis is the axis of the handle pivot shaft (142) that is the center of rotation of the traction handle (104) and handle pivot shaft nut (164) relative to the intermediate member (106) of the traction member (100). It is.

As shown in FIGS. 10 and 11, the traction handle (104) can be oriented with respect to the arm portion (102) of the traction member by turning about the plurality of axes of the traction member (100) of the second embodiment. Become. FIG. 10 shows the orientation of the traction handle (104) such that the grip (134) of the traction handle (104) is parallel to the first axis. In this orientation, the traction handle (104) can be easily retracted into the baggage in a manner similar to that described with respect to the traction member (20) of the first embodiment. As shown in FIG. 11, the traction member (104) is pivoted about the first and second axes, the second axis extends vertically, and the grip portion (134) of the traction handle is aligned with the first axis. It extends horizontally in a plane perpendicular to the horizontal axis. In this orientation, the grip (134) of the tow handle (104) is ideally positioned for the user to tow the bag without flexing its wrist, regardless of the angle of inclination of the bag.

A third embodiment of the traction member includes the traction handle (200) and connector (202) shown in FIGS. FIG. 12 shows an exploded view of the traction handle (200) and connector (202) of the third embodiment of the traction member.

Generally, the traction handle (200) of the third embodiment of the traction member comprises a lower portion (204), an upper portion (206), two end caps (208), preferably unlocked, preferably made of a polymeric material. / Release button (210). As in the first and second embodiments, the traction handle (202) of the third embodiment is preferably T-shaped. The lower portion (204) of the traction handle (200) forms half of the traction handle handle (212), preferably an integrally formed base that extends orthogonally from the handle portion along the central axis of the traction handle. (214). The base (214) forms a cylindrical shaft (216) and is provided with a neck that terminates in a locking projection (218). The lock projection (218) basically comprises a cylindrical shape with two intersecting channels (220) formed in the end face (222). These channels (220) are preferably orthogonal to each other and intersect in the axis of symmetry of the traction handle. Although the reason will be described later, each channel (220) preferably includes opposing walls that slightly extend from each other as it extends radially from the central axis. A through hole (226) is aligned with the central axis of the traction handle (200) and extends through the lower portion (204). Finally, a plurality of grooves (228) are formed in the lower handle (212) portion of the traction handle (200) to improve gripping by the user of the traction handle and enhance the aesthetics of the traction handle.

The upper portion (206) of the traction handle (200) has a generally semi-cylindrical curved shape that forms the upper half of the traction handle handle (212). An opening (230) having an elliptical outer periphery is formed through the center of the upper portion (206).

The end caps (208) of the traction handle (200) are preferably identical to each other and are preferably formed as a flat plate with an elliptical perimeter. A pair of counterbore screw holes (232) preferably extend through each end cap (208).

The unlock / release button (210) includes an elliptical protrusion (234) with a circumscribed rim (236) formed around it. The elliptical protrusion (234) is slightly smaller in size than the elliptical opening (230) of the upper portion (206) of the traction handle (200) so that the elliptical protrusion can pass through the opening. To do. However, the rim (236) of the unlock / release button (210) is dimensioned to be larger than the elliptical opening (230) of the upper portion (206) of the tow handle (200) so that the unlock / release button (210). Prevent the whole from passing through the opening. The opposite end of the unlock / release button (210) includes a rod (238) that projects like a cantilever from the rest of the button. The rod of the unlock / release button (210) is preferably cylindrical.

The connector (202) of the third embodiment of the traction member includes two halves (240) and locking member (242) of the same shape, preferably formed of a polymeric material. Each of the connector halves (240) includes a cavity (244) generally surrounded by a peripheral ridge (246). A flat surface (248) is formed in the cavity (244), and a pair of tubular posts (250) extend orthogonally from the flat surface. In addition, each connector half crack (240) also includes a semi-cylindrical journal surface (252) formed in the outer circumferential ridge (246). A semi-cylindrical channel (254) with a slightly larger radius than the journal surface (252) is formed in the cavity (244) adjacent to and aligned with the journal surface. The journal surface (252) is sized to correspond to the length and diameter of the cylindrical shaft (216) of the base (214) of the traction handle (200). A smaller semi-cylindrical opening is aligned with the journal surface (252) and formed on the opposite side of the outer perimeter ridge (246) of each connector half crack (240). Finally, a plurality of alignment pins (258) and alignment holes (260) are formed in the outer perimeter ridge (246).

The locking member (242) of the connector (202) is generally rectangular and includes a pair of back-to-back parallel surfaces (262). A pair of elliptical slots (264) penetrates from one of the back-to-back parallel surfaces (262) to the other. The lock member (242) includes an upper end (266) and a lower end (268) which are opposite to each other, and a cylindrical blind hole (270) extending toward the upper end.

Having described the various components of the traction handle (200) and connector of the third embodiment of the traction member, the assembly of these components will now be described. To assemble the traction handle (200) of the third embodiment of the traction member, first the rod (238) of the unlock / release button (210) is inserted into the through hole (226) of the lower portion (204) of the traction handle. Slide in from above. When this is complete, the upper portion (206) of the traction handle (200) is engaged with the lower portion (204) of the traction handle. When this is complete, the oval protrusion (234) of the unlock / release button (210) is positioned through the opening (230) of the upper portion (206). When the upper portion (206) and lower portion (204) of the traction handle (200) are engaged with each other, the rim (236) of the unlock / release button (210) is more than the opening (230) in the upper portion of the traction handle. Being large, the unlock / release button is captured between the upper and lower parts. Using the screw (not shown) inserted into the screw hole (232) of the end cap with the upper portion (206) and the lower portion (204) of the traction handle (200) engaged with each other, the end cap Attach (208) to both ends of the pull handle handle (212). With the end cap (208) attached as described above, when the upper portion (206) and lower portion (204) of the traction handle (200) are secured together, the upper and lower portions will remove the end cap. Without it, it becomes impossible to separate.

The connector (202) is assembled to the lower part (204) of the traction handle (200). To do this, first position the shaft (216) of the base (214) of the lower part (204) of the traction handle (200) with respect to the journal surface (252) of any connector half crack (240). To do. Next, with one of the back-to-back parallel surfaces (262) engaged with the flat surface (248) of the connector half crack (240) and the blind hole (270) of the locking member facing away from the traction handle, The locking member (242) of the connector (202) is positioned. In this position, the post (250) of the connector half crack (240) extends partially into the elliptical slot (264) of the locking member (242). Finally, the other connector half crack (240) is attached to the assembly by aligning each connector half crack alignment pin (258) with the other connector half crack alignment hole (260). In addition, the half cracks are attracted to each other until the peripheral ridges (246) of each half crack are engaged with each other. When these half-splits (240) are engaged with each other as described above, each connector half-split post (250) engages the other half-split post in the elliptical slot (264) of the locking member (242). Determine the size and shape of the connector half cracks. This prevents the flat surface (248) of the connector half crack (240) from pinching the locking member (242) between them. Thus, the locking member (242) is trapped in the internal volume of the connector (202) formed by the cavity (244) of the connector half crack (240), but the base (214) of the traction handle (200). It is always possible to translate freely in the direction toward and away from. The traction handle (200) itself can always pivot about the central axis with respect to the connector (202) except when locked as described later, but the lock protrusion (218) is half-cut into the connector ( 240) is trapped between the semi-cylindrical channels (254) and cannot be pulled out of the connector.

When assembled in this manner, the traction handle (200) and connector (202) of the third embodiment are then preferably provided with an arm portion (as shown) of the type of traction member described in connection with the traction member of the first embodiment. Attach to the distal end. Like the first embodiment of the traction member, the connector (202) of the third embodiment is preferably sized to fit into the tubular end of the arm portion. When this is complete, the release member (272) is removed from the locking member (242) through the opening at the proximal end of the connector (202) formed by the semi-cylindrical opening (256) of the connector half crack (240). Insert into blind hole (270). Release member (272) is configured and adapted to actuate a locking mechanism (not shown) when it is pushed into and retracts the arm portion into the baggage with the arm portion of the traction member attached. . Such release members and locking mechanisms are well known in the field of the present invention, and their specific configuration and details are not relevant to the present invention unless otherwise specified. However, the traction handle (200) and connector (202) of the third embodiment are specifically configured to operate in combination with a release member of the type that is spring biased toward the traction handle. As described above, when the connector (202) is assembled to the arm portion of the traction member, a pair of fasteners (not shown) are routed through the distal end of the arm portion and the connector post (140) tubular post (140) 250) to complete the assembly process by fixing the connector to the arm portion of the traction member.

Once assembled, the traction handle (200) can be selectively locked in two orientations relative to the connector (202) and arm portion of the traction member of the third embodiment. To illustrate how this is accomplished, the traction handle (200) and connector (202) assembly is shown in FIGS. 13-16 with one connector half crack (240) removed. In the first orientation shown in FIG. 13, the traction handle (200) is positioned such that its handle (212) is oriented generally parallel to the flat surface (248) of the connector half-crack (240). . In this position, the locking member (242) of the connector (202) moves toward the traction handle (200) due to the biasing force of the release member (272), so that the upper end portion (266) of the locking member is pulled. Enter any of the channels (220) formed in the locking protrusion (218) of the handle. The locking member (242) is positioned between the opposing walls (224) of the channel (220), so that the opposing walls of the channel are engaged with the locking member. With respect to (202), free rotation about the central axis of the handle is prohibited. However, the opposing walls (224) of each channel (220) are dimensioned to be slightly spaced apart from the back-to-back parallel surfaces (262) of the locking member (242), and the traction handle (200) When locked in the first orientation, a slight turn in the range of approximately a 20 degree arc relative to the connector (202) is possible.

If required, the traction handle (200) can be selectively locked in a second orientation relative to the connector (202) and the traction member. To do this, push the oval protrusion (234) of the unlock / release button (210) on the traction handle (200) and rotate the handle to the second orientation shown in FIG. When the unlock / release button (210) is pushed in as shown in FIG. 14, the rod (238) of the unlock / release button (210) causes the lock protrusion (218) of the base (214) of the traction handle (200). ) And into the locking member (242) of the connector (202). This action exceeds the biasing force applied to the locking member (242) by the release member (272), forcing the locking member away from the traction handle (200), and thus the upper end portion (266) of the locking member to the traction handle. The lock projection (218) of the channel is separated from the channel (220). Then, as long as the unlock / release button (210) is pushed, the tow handle (200) can freely rotate with respect to the connector (202).

If desired, the traction handle (200) can now be locked in a second orientation relative to the connector (202) and arm portion of the traction member. To do this, the tow handle (200) is rotated to the second orientation and then the tow handle unlock / release button (210) is released. When the unlock / release button (210) is released, the biasing force of the release member (272) again forces the lock member (242) to move toward the traction handle (200), resulting in the lock member The upper end portion (266) enters the other channel (220) formed in the lock protrusion (218) of the traction handle. Accordingly, as shown in FIG. 16, the opposing wall (224) of the channel (220) engages the locking member (242), so that the traction handle (200) is rotated around the central axis of the handle relative to the connector (202). Free rotation is prohibited again. As described above, the opposing walls (224) of each channel (220) are dimensioned to be slightly larger in distance than the back-to-back parallel surfaces (262) of the locking member (242). It should be understood that when the handle (200) is locked in the second orientation, a turn of approximately 20 degrees arc relative to the connector (202) is still possible here. The unlock / release button (210) can be depressed at any time to adjust the orientation of the traction member (200) as desired relative to the rest of the traction member. It is further understood that when the unlock / release button (210) is depressed, the release member (272) elastically moves away from the traction handle (200) due to the action of the locking member (242) inside the connector (202). I want. Therefore, when the lock release / release button (210) is pushed, the release member (272) activates the lock mechanism, and the arm portion of the traction member can be pulled into the baggage.

As described above, the traction handle (200) of the third embodiment of the traction member can pivot in the same manner as the traction handle of the first embodiment with respect to the rest of the traction member. However, the traction handle (200) can be locked in any of multiple orientations relative to the remainder of the traction member. This lock function allows a user to tow the baggage to apply torque to the shaft of the tow member if desired, and therefore when towing the baggage (20) on an uneven ground such as a roadside. , Can prevent unintended fall of baggage.

Similar to the first to third embodiments, the fourth embodiment of the traction member of the present invention is particularly adapted and configured to be an integral part of the baggage. The fourth embodiment is generally similar in appearance and operation to the second embodiment, but, like the third embodiment, the structure incorporates a locking mechanism and an unlocker. In the fourth embodiment, the locking mechanism is specifically designed to unlock the handle by single button activation by the user and allow free movement of the handle along multiple allowable motion axes. In the embodiment shown in FIGS. 17 to 25, this structure has only two different positions set on the button, so when the button is depressed, both axes of motion are released simultaneously. However, in another embodiment, it is possible to modify the structure described below to release the movement along only one axis by pressing a specific button and to release the other axis by the second action. The trader should understand. For example, it is possible to release one rotating shaft by pushing the button to a first predetermined depth and release the second rotating shaft by further pushing. Furthermore, in other embodiments, multiple buttons (eg, one for each axis) can be used.

FIG. 18 shows an overall view of an embodiment of a lock handle that allows movement in two axes, which can be locked or unlocked at any of a plurality of predetermined positions to provide two axes of the handle. Free operation is possible. The pulling member (700) of the fourth embodiment preferably comprises an arm portion (702), a handle (704), and an intermediate member (706). Although not shown in the drawings, the traction member (700) of the fourth embodiment is configured to be attached to the towable baggage in a manner similar to the traction member (102) of the second embodiment. Also, arm (702) is preferably formed from three tubular sections (802), (902), and (602). Tubular sections (802), (902), and (602) have an oval, oval, or eight-shaped cross-section, and are configured to slide one into the other in a nested manner, and the second The arm portion (102) of the embodiment or the arm portion (24) of the first embodiment is curved and configured in a similar manner. In the description of the fourth embodiment, if details of the method of attaching the traction member to the baggage are not described, it should be considered similar to the attachment configuration of the other embodiments. However, it should be understood that the fourth embodiment can be attached to baggage, particularly in a manner similar to the second embodiment, or in other ways known in the field of the invention.

Figures 19-22 show a cutaway view of the handle (704) of the system and the first tubular section (802) to which the handle is coupled. Like the arm portion (102) of the second embodiment, the outermost first tubular section (802) of the fourth embodiment is a two-pole member that slides into and out of a single slot in the baggage. It is preferable that The first tubular section (802) has a proximal end (808) that slidingly engages the second tubular section (902) and an opposite distal end that is retractable toward and away from the baggage. (708) has a certain length. Although not limited as a material, a pair of spaced tubular members (710), which can be formed from aluminum, steel, or other suitable high strength material, is a proximal end (808) of the first tubular section (802). To the distal end (708) of the tubular section (802). Tubular members (710) of the first tubular section (802) extend generally parallel and close to each other over the entire length of the first tubular section (802), opposite the proximal end (808) and the far end. It is preferred that they are firmly connected to each other at the distal end (708). For this connection, the end cap (811) may be used at the proximal end (808), and the connection structure described below may be used at the distal end (708). Accordingly, the two tubular members (710) of the first tubular section (802) function generally similar to conventional single pole members, so that these two members are primarily single aesthetic tubular members for aesthetic purposes. It is used instead of. Finally, it is preferred that at least one through-hole (712) is formed through each tubular member corresponding to a tubular member (710) that is generally considered hollow. The first tubular section (802) is plugged into the second tubular section (902), and the second tubular section is plugged into the third tubular section (602), which can be a port of the arm portion (702) of the baggage. In other embodiments, any number of tubular sections may be used, and the telescoping connection may be realized by other structures in other ways.

Further, the first tubular section (802) includes a pair of distal end caps (716), which can be, but are not limited to, polymeric material or metal. Each end cap (716) has a generally elbow shape and includes a base (718) configured and adapted to socket-fit over the distal end (708) of one tubular member (710). Yes. A shoulder (not shown) is formed in each end cap (716) adjacent to the base (718) and abuts the distal edge (708) of each tubular member (710) such that the end cap is Further sliding into the tubular member is prevented. A first through hole (722) may be formed through each base (718) of the end cap (716). When the base of the end cap (716) is fitted over the tubular member (710) and the shoulder of the end cap (716) abuts the distal edge (708) of the tubular member (710), the penetration of such base The holes (722) are generally aligned with the through holes (712) of the corresponding tubular member (710). In an alternative embodiment, the end cap need not include a through hole (722) and the internal structure may be solid. The connection of the end cap (716) to a suitable tubular member (710) may be in the field of the present invention including, but not limited to, adhesives, fasteners, welds, or other types of fasteners. Any means known to those skilled in the art having ordinary skills may be used.

Each end cap (716) further includes a planar support surface (726) oriented orthogonally to its base. The support surface (726) preferably comprises a generally circular perimeter. The second through hole (728) may be formed to pass through each of the support surfaces (726), and the second through hole is preferably located at the center of the support surface (726) and orthogonal to the surface. This through hole (728) can later be used to accommodate the bullet shaft (691). In another embodiment, the through hole (728) may be omitted and the end cap (716) may be solid. When the second through hole (728) is included, the diameter is preferably substantially the same as that of the first through hole (722), but this is not a necessary condition.

Mounted on the support surface (726) is a collar (791) that is generally circular and generally smaller in diameter than the diameter of the support surface (726). The collar (791) is fitted with a slotted ring (751) that is also generally circular and whose outer diameter is larger than the diameter of the collar (791) but is generally smaller than the diameter of the support surface (726). In alternative embodiments, larger or smaller slotted rings (751) may be used. When the second through hole is provided, the collar and the slotted ring (751) pass through, and the slotted ring (751) and the collar (791) are hollow. Even when the second through hole is not provided, the slotted ring (751) is a generally hollow ring that goes around the opening. Each slotted ring (751) includes at least one slot (753). The slot (753) is a notch that penetrates the side wall of the slotted ring (751) in the radial direction of the ring (751), so that the opening around which the ring circulates is formed in the outer space of the slotted ring (751). Communicate (or simply form an opening in that direction, even if not completely connected to the external space). Each slot (753) has a predetermined width and depth. This width is selected in advance to be equal to or greater than the thickness of a paddle (771) described later. This depth may be any depth, and may be any depth equal to or less than the depth of the slotted ring. However, this depth is preferably sufficient to engage and hold an object with a width similar to that of the slot (753), but not so deep that the object is twisted out of the slot. Set. The slotted ring (751) of one end cap (716) is generally parallel to and spaced from the slotted ring (751) of the other end cap (716).

From FIG. 19, the traction handle (740) of the fourth embodiment of the traction member (700) is preferably made of a polymeric material and / or metal, but those skilled in the art having ordinary skill in the field of the present invention. Alternatively, any known material may be used. The tow handle (704) is generally “T” shaped (although it can be offset as shown) and has a grip (734) and a base (738) with free ends (736) opposite each other. Including. Although the base (738) of the tow handle (704) is preferably integrally formed with the grip (734), it is not a requirement. The grip (734) and the base (738) are preferably generally hollow. The base (738) intersects the grip (734) and preferably extends orthogonally from the grip. A circular support surface (740) is formed at the end of the base (738) and is spaced from the grip (734).

The intermediate member (706) of the traction member (700) is preferably two half-cracks made of a polymeric material that are subsequently joined by any method known to those skilled in the art with ordinary skill in the art. However, it may alternatively be made from any number of parts. The intermediate member (706) has a generally “T” shaped structure, and a pair of first and second circular support surfaces (746), (748) are at opposite ends of the intermediate member (706). Formed, parallel and spaced apart from each other. A third circular support surface (750) is formed in the intermediate member (706) and is oriented orthogonally to and spaced from the first and second circular support surfaces (746) and (748). The intermediate member (706) is preferably generally hollow. Further, each of the three support surfaces described above has a through-hole that passes through the inside. The through hole is surrounded by a ridge (846), (848), or (850), where the design of the ridge (846), (848), or (850) is The size of the through-hole has a diameter and thickness that matches the outer diameter of the collar to which the arm portion of the intermediate member is mounted, while the hollow section inside provides a larger opening. Specifically, in the state in which the slotted rings (773) and (751) are accommodated in the hollow interior of the intermediate member (706), the ridge (846), (848), or (850) 773) and (751) side ridges (846) and (848) orbit the collar (791) of the end cap (716) to prevent the intermediate member from being pulled out of the hollow interior. The strip (850) goes around the collar (873) of the swivel shaft (742). It should be understood by those skilled in the art that this collar / ridge structure allows rotational movement while preventing linear movement of the intermediate section (704).

20 and 21 illustrate the internal structure of the portion of FIG. 19 with the grip (734) and base (738) removed. Inside the grip part (734), one end part (737) includes an opening part (739). A part of the button mechanism (741) is provided through the opening (739). In a preferred embodiment, a portion of the structure of the button mechanism (741) extends a predetermined distance through the opening (739) described above. This portion is covered with a button cover (743). Further included is a biasing member (745) (in this case a spring) that biases the button mechanism (741) to a position where the aforementioned portion extends through the opening (739). The button mechanism (741) comprises a lip, shoulder or similar portion, and when biased by the biasing mechanism (745), the button mechanism extends partially beyond the opening (739). The opening (739) cannot be freely removed.

The tow handle (704) also includes a handle pivot shaft (742) and a handle push pin (747) that are generally perpendicular to the handle (734) and extend within the base (738). The handle pivot shaft (742) is preferably generally tubular and includes a central through hole (842) in which the handle pusher pin (747) can slide. The pivot shaft (742) is generally not fixed to the button mechanism (741), but is firmly connected to the base (738). The push pin (747) is designed to convert the user's movement from pushing the button mechanism (741) into a linear displacement of the push pin (747) in the through hole (842) in the pivot shaft (742). ing. In the illustrated embodiment, this is achieved by designing the push pin (747) to include a forming head (749) on one side. The button mechanism includes a recess (751) of a corresponding size, and the button mechanism (741) is urged toward the button mechanism (741) through the opening (739) by an urging mechanism (not shown). Then, the forming head (749) is accommodated in the recess. When the button mechanism (741) is pushed against the biasing force of the biasing member (745) by the user, the mating angle (original: mating)
angles) slide relative to each other, causing the pusher pins (747) to be linearly displaced over a fixed distance along the axis of the pivot shaft (742) within the base (738) and pivot shaft (742). One of ordinary skill in the art will appreciate that the illustrated button mechanism (741) is but one example of a number of different types of button mechanisms that can be used. In an alternative embodiment, the button mechanism can be designed to push in another direction (eg, linearly in the direction of displacement of the push pin), and with appropriate design choices, any button movement can be achieved. The linear motion of the push pin (747) along the axis of the pivot shaft (742) can be converted. Those skilled in the art with ordinary skills should understand that this movement is also realized by the buttons of the third embodiment which can alternatively be used here.

The push pin (747) and the through hole (842) have a non-circular cross section, or the push pin (747) rotates about the axis of the pivot shaft with respect to the pivot shaft (742), Alternatively, it is preferable to prevent the rotation in the other manner in the through hole (842). In a preferred embodiment, the push pin (747) and the through hole (842) are both generally square cross-sections, and more preferably square cross-sections.

A paddle (771) is held at the base of the push pin (747). The paddle (771) is shown separated from other structures in FIG. 22, but is shown in a state of being incorporated in the handle (704) in the other figures. The paddle (771) has a generally planar shape with a predetermined thickness and may be an “arrowhead” shape, but other shapes may also be used as would be understood by one skilled in the art with ordinary skills. The paddle (771) is attached to the push pin (747). However, the linear displacement of the push pin (747) becomes the linear displacement of the paddle (771), and the push pin (747) is rotated with respect to the paddle (771). 742) so as to be freely rotatable around the axis. In the illustrated embodiment, this is accomplished by hollowing the push pin (747) and attaching a paddle pin (890) to the edge of the paddle (771). This detail of this paddle is shown in FIG. The paddle pin (890) is preferably a cylindrical configuration or another type of configuration, and the paddle pin (890) can freely rotate about the axis of the pivot shaft (742) within the hollow center of the push pin (747). Like that. To assemble this structure, the paddle pin (890) is housed inside the hollow center of the push pin (747). Further, the paddle (771) is urged toward the pushing pin (747) by an urging mechanism (not shown), and the paddle pin (890) can be placed in the pushing pin (747) as shown in FIG. Insert as deeply as possible. The linear motion of the paddle (771) causes the outer structure of the push pin (747) to move to the edge of the paddle (771) and / or paddle pin (890) when the push pin (747) is displaced by the button mechanism (741). Realized by being pressed against the part.

The base of the pivot shaft (742) is provided with a collar (873) and a slotted ring (773) similar in design to the slotted ring (751). The slotted ring (773) includes at least two coplanar and parallel slots (874) formed therethrough. Each slot (874) has a width approximately equal to the thickness of the paddle (771) and is generally similar to the slot (753) of the slotted ring (751). A through hole (842) extends through the collar (873) and slotted ring (751) described above, with the second through hole (728) supporting the end cap (716). It is approximately the same as extending through the surface and associated collar (846) or (848) and slotted ring (751).

The locking and unlocking of the biaxial movement of the handle is performed by moving the paddle (771) between two positions based on the push-in or push-out of the button mechanism (741). In the first position (shown in FIG. 21A), paddles (771) are positioned within at least one slot (753) of each slotted ring (751) and at least one slot (973) of slotted ring (773). (Generally two parallel slots). In the second position (shown in FIG. 21B), the paddle is linearly displaced from these slots and is positioned above the slotted ring (773) in the space in the opening around which the slotted ring (751) circulates. To do. Paddle (771) is displaced into the hollow interior of intermediate member (706), clearing slots (874) and (753). These positions correspond to “locked” and “unlocked” positions, respectively.

To better understand the locking and unlocking operations, it is easiest to describe the interrelationship of the intermediate member (706), pivot shaft (742), and end cap (716) during operation. The intermediate member rotates the ridge (850) of the intermediate member (706) around the collar (873) of the pivot shaft, thereby supporting the support surface (973) of the pivot shaft (742) and the support surface of the base (738). (740) is freely rotated on the support surface (750) of the intermediate member. Similarly, by rotating the appropriate ridge (846) or (848) over the appropriate collar (791), the support surface (726) of the end cap (716) also becomes the support surface (746) or ( 748).

Assuming there is no paddle (771), the handle (704) can pivot through two interrelated ranges of motion similar to those allowed in the second embodiment. However, in this case, the end portions of the ridges (846) and / or (848) are not used without using the two pins of the second embodiment, which are the centers of rotation of the interlocking member (706) and the base (738). The rotation of the cap (716) about the collar (791) and the rotation of the pivot shaft collar (873) on the ridge (850) of the intermediate member (706) are replaced. Specifically, the handle (704) can rotate about the axis of the pivot shaft (742) by rotating the pivot shaft (742) relative to the intermediate member (706). Further, the intermediate member (706) and handle (704) can rotate about an axis orthogonal to the support surface (726) of the end cap (716). This movement is similar to the movement described above with respect to the second embodiment and allows rotation about two different (and generally orthogonal) axes by the handle. These axes are preferably aligned with the baggage similar to the axes of the second embodiment, but such an arrangement is not a requirement. This structure only allows rotational movement about these two axes, and all other movements are prohibited by the structure of the intermediate member (706), handle (704), or end cap (716). Should be obvious.

The possible movement in the absence of the paddle (771) is identical to the movement when the paddle (771) is in the hollow of the intermediate member (706), and therefore the movement when the paddle (771) is in the unlocked position. Corresponds to. In the illustrated embodiment, when the user pushes the button mechanism (741), it exceeds the biasing force, the push pin (747) moves linearly away from the handle (734), and this action of the push pin (747) The paddle (771) is moved away from the handle (734), and the paddle is moved from within the slot. The push pin (747) is free to rotate about the paddle (771) once released from the slot. It is preferable to inhibit the movement of the paddle (771) about the same axis as described above by any method known to those skilled in the art with ordinary skills, for example, another pin is placed inside the intermediate member (706). Further, it may be provided so as to pass through the hole (891) of the paddle (771), and its rotation may be prohibited (this is orthogonal to the page of FIG. 20). Also, the combination of the paddle (771) and the intermediate member (706) can rotate freely with respect to the end cap (716).

Once the paddle (771) is moved from the obstruction position, the traction handle (704) can pivot about two axes relative to the arm portion (702) of the traction member. By pivoting about the multiple axes of the traction member (700) of the fourth embodiment, the traction handle (704) can be oriented as shown in FIGS. 17A, 17B, and 17C.

Slotted rings (773) and (751) define the locking position of the paddle that locks the handle (734) in place. If the paddle (771) is retracted in the direction of the handle (734), it enters into one slot of each adjacent slotted ring (751). Upon entering this slot (because the width of these slots is only the paddle thickness), the solid portion of the slotted ring (751) impedes paddle movement, so the paddle is centered about the axis between the end caps. Rotation is prohibited. Further, since the pusher pin can only move linearly with respect to the handle (734), at this point the handle is locked in place relative to an axis perpendicular to the support surface of the end cap (716).

Pulling the paddle (771) into the two parallel slots of the slotted ring (773) yields similar results for the axis of the pivot shaft (742). The rigid design of the paddle (771) prevents the pivot shaft (742) from rotating relative to the paddle (771) when the paddle is in the slot (973). At this point, if the paddle (771) can freely rotate about the pivot shaft (742) axis, the paddle (771) can rotate with the pivot shaft, and the handle (704) should not be fixed. However, since the paddle (771) and the intermediate member (706) are not joined, they should not be able to rotate together, but in a preferred embodiment, the paddle is slotted on the pivot shaft (742). When in the slot (973) of the ring (773), the paddle (771) is also in the slot (753) of the slotted ring (751) of the end cap (716). Thus, since the paddle (771) is obstructed by the slotted ring (751), the slotted ring (751) prevents the paddle (771) from rotating about the pivot shaft (742) axis (further. It is preferable to prevent the paddle from rotating on this axis even at the locked position by a design that prevents the paddle from rotating on this axis at the unlocked position). This obstruction prevents the push pin (747) and the pivot shaft (742) from rotating about the axis of the pivot shaft (742).

As described above, the design of the pivot shaft (742) prevents the shaft from rotating about the push pin (747) on the axis of the pivot shaft (742), and thus the push pin (747) and the pivot shaft (742). ) Are secured to each other and neither can rotate freely, so it is preferable to prevent movement on any axis by the handle (704). This corresponds to the locked position, in which the handle (704) is not moved with respect to any axis.

If any slot is aligned with paddle (771), paddle (771) is preferably biased to that position within slots (973) and (753). If there is a slot into which the paddle (771) can enter, the paddle will attempt to return to a position within that slot. The slotted rings (773) and (751) allow the user to push in the button mechanism (741), move the handle (734) slightly, further release the button mechanism (741), and move the handle (704) to the ring. Can be moved to a desired position (assuming there is no slot between the original position and the desired position slot). If the button mechanism (741) is released when the paddle (771) is not aligned with the set of slots, the paddle (771) cannot be retracted into the slot and the slotted ring (773) and / or ( Only the surface of 751) is drawn. In this position, the paddle (771) can move smoothly over the ring surface without interfering with the movement of the handle (734) and eventually the paddle (771) is aligned with a series of slots, It is energized inward and movement is prohibited.

In the embodiment shown in FIGS. 20 and 21, due to the dimensions of the slotted rings (773) and (751), to retract the paddle (771) into the set of slots (973) or (753), one Since the slotted ring prevents the paddle (771) from being pulled into the other slotted ring, the paddle (771) must also be able to be retracted into the second set of slots (973) or (753). Yes, it should be clear. This means that the user has released or locked the movement of both axes. While this has several advantages, one skilled in the art may allow the paddle (771) to enter another series of slots in alternative embodiments, even if the series of slots are occupied. Those skilled in the art should understand this.

The slots (973) and (753) corresponding to the preselected position that the user wishes to lock the handle (704) can be selected. In this way, the handle (704) can be moved to a predetermined desired position and locked there. This locking action allows the user to freely change the position of the handle as shown in FIGS. 17A and 17B, but FIGS. 17A and 17B show that one axis can move between two different positions. FIG. 17C shows the locked position with both axes adjusted. Since the handle (704) is held in the position of FIGS. 17A, 17B, and 17C by the locking mechanism, the user need not use wrist muscle tissue to maintain the handle (704) in this preselected position. Absent.

In some embodiments of the fourth embodiment, it may be desirable to release the locking mechanism that maintains the stretched state of the arm portion (702) by pushing the button mechanism (741). To accomplish this, additional structures may be included in at least one of the end caps (716). As shown in FIG. 23, the end cap can incorporate a bullet shaft (691) that slides linearly within the second through-hole (728) to end cap (716). Designed to enter. When the user pushes on the button mechanism (741) and the paddle (771) is pushed into the intermediate section (716), the bullet shaft (691) is pushed into the end cap (716). The arrowhead shape of the paddle (771) can act on the opposing angle of the bullet shaft (601) in the same manner that the button mechanism (741) acts on the push pin (747). The bullet shaft (601) can then push the handle shaft (811) extending through the first tubular section (802). Referring now to FIGS. 24-25, which show the proximal end (808) of the first tubular section (802), the handle shaft (811) extends, which causes the interference cap (605) to actuate the key paddle (603). Pushing, this time the key paddle pulls the extension pin (607) into the hole (609) in the end cap (811). When the extension pin (607) is biased and the handle shaft (811) is not displaced by the displacement of the button mechanism (741), the extension pin is moved from the hole (609) to the second tubular section (902). It is preferable to make it the state extended | stretched through this opening part (809). Through this opening (809), the tubular sections (802) and (902) are maintained in a stretched state relative to each other, and the draw pins (607) impede their relative movement so that they cannot be retracted. It becomes.

When the button mechanism (741) is pushed in by the user, releasing the movement of the handle (734) on both pivots then releases the lock on the arm part (702) and the arm part shrinks back-nesting. It becomes possible. Those of ordinary skill in the art can further transform the movement of these components to release additional locking mechanisms, such as releasing the locking device and extending the arm portion (702). Should understand. As a logical development, this single button push could be used to unlock the movement of any part of the traction member (700) relative to any other part. Accordingly, single button release of the traction member (700) is feasible.

For those skilled in the art, the fourth embodiment shown in FIGS. 17-25 is only one embodiment of a locking mechanism that releases the handle to allow movement in two axes and an optional release of an additional locking mechanism. You should understand that. Other structures can be used without extensive experimentation. For example, the paddle (771) may have a shape other than “arrowhead” unless the button press only releases two axial movements and is not specifically translated to other movements. Further, it is not necessary to use a paddle and slotted ring locking mechanism, and other structures can be used as a locking mechanism to push the button mechanism and release the biaxial motion. Furthermore, as briefly mentioned, the two-axis motions do not need to be released simultaneously, and in alternative embodiments, one exercise can be released earlier than the other, or the user can release either exercise first. May choose to do so, release both axes at the same time, or move the movements together in other ways.

While this invention has been disclosed in connection with certain preferred embodiments, this disclosure is not to be construed as a limitation on the overall details described. The embodiments described above can be modified or changed without departing from the spirit and scope of the present invention, and other embodiments are also encompassed by the present disclosure, as will be appreciated by those of ordinary skill in the art. It should be understood that it is good.
