Technical Field
[0001] (Related Applications) This application claims the benefit of priority of U.S. Provisional Patent Application No. 62 / 855,747, filed on May 31, 2019, and U.S. Provisional Patent Application No. 63 / 001,673, filed on March 30, 2020, the contents of both of which are incorporated herein by reference.
[0002] The present disclosure generally relates to golf equipment, and more particularly to a strap assembly for a carry bag.
Background Art
[0003] Generally, golf bags are classified into carry bags and cart bags. Carry bags typically include a strap system that enables a user to support the weight of the bag on the shoulder. In some carry bags, the strap system is a single strap system that allows the user to carry the bag on one side of the body. There are also carry bags where the strap system is a double strap system that allows the user to carry the bag like a backpack.
[0004] Carry bags are typically designed with either a single strap system or a double strap system. The single strap system has the drawback that the user's upper body and shoulders become fatigued due to uneven load, which may impede their performance on the golf course. The double strap system overcomes this drawback by providing the user with the option of evenly distributing the weight of the golf bag across both shoulders, reducing overall fatigue. However, short-distance golfers may prefer the convenience of the single strap system. Additionally, a caddie carrying two bags cannot use both straps attached to a double strap bag and instead has to carry the two bags by placing a single strap of each bag on each shoulder.
[0005] Double strap systems often have cross-shaped straps that are carried on the back like a backpack. In some double strap designs, the bag can be lifted by a single strap and carried on the user's right side. However, due to the orientation of the double strap design, the user cannot conveniently use the single strap on the left side of their body. This strap is not configured to accurately distribute the weight of the bag when it is carried on the user's left side. In addition, because the two straps are fixed together at the cross-shaped point, the double strap system does not function well for single-strap carrying, regardless of whether the bag is carried on the left or right side of the body. The cross-shaped point can hit the user's elbow when the user is picking up the bag by grasping the single strap. Considering these problems, there is a need in the art for a strap system that can be converted from a double strap system to a single strap system and vice versa. [Brief explanation of the drawing]

[0023] The invention described herein is a convertible strap system for a golf bag. The strap system is convertible between a single-strap configuration and a double-strap configuration. The strap system may comprise a first strap 102, a second strap 108, and a backpack 100. In the double-strap configuration, the backpack 100 can orient the first strap 102 and the second strap 108 relative to each other. The first strap 102 can be engaged with the backpack 100 in a non-removable manner, while the second strap 108 can be engaged with the backpack 100 in a removable manner. In the single-strap configuration, the second strap 108 can be detached from the backpack 100. In the double-strap configuration, the second strap 108 can be engaged with the backpack 100 in a translationally responsive manner.
[0024] As shown in Figures 1, 12, and 13, the first strap 102 can be discontinuous. The first strap 102 may comprise a first portion 104 and a second portion 106. The backpack 100 can be connected between the first portion 104 and the second portion 106 of the first strap 102. The first portion 104 may comprise a first end and a first attachment end 110. The first end can be attached to a golf bag. In some embodiments, the first end is offset to the right side of the golf bag and attached to the back of the golf bag. The first attachment end 110 can be attached to the backpack 100. In some embodiments, the first attachment end 110 is attached to the backpack 100 in a non-removable manner, attached, sewn, and / or detachably attached using a snap-fit or other detachable attachment mechanism. The second portion 106 may comprise a second end and a second attachment end 112. The second end can be attached to a golf bag. The second attachment end 112 can be attached to the backpack 100. In some embodiments, the second attachment end 112 is non-removably coupled, attached, sewn, and / or detachably attached to the backpack 100 using a snap-fit or other detachable coupling mechanism. In some embodiments, the second end can be offset toward the left side of the golf bag and coupled to the back of the golf bag. In some embodiments, the first and second ends of the first strap 102 can be configured to be detachable from the golf bag. In some embodiments, the first strap 102 further comprises a padded portion.
[0025] The discontinuity of the first strap 102 prevents the first strap 102 from rubbing against and causing friction with the second strap 108. The second strap 108 can slide freely through the backpack 100 without being hindered by the intersection of the first strap 102 attached to the edge of the backpack 100. However, in some embodiments (not shown), the first strap 102 can be continuous so as long as the second strap 108 is positioned below the first strap 102 in the channel, the second strap 108 does not come into contact with the first strap 102.
[0026] The second strap 108 can be continuous. The second strap 108 can have a first end and a second end. The first and second ends can be attached to the golf bag. The first end of the second strap 108 can be offset toward the left side of the golf bag and attached to the back of the golf bag. The second end of the second strap 108 can be offset toward the right side of the golf bag and attached to the back of the golf bag. In some embodiments, the first and second ends of the second strap 108 can be configured to be detachable from the golf bag. In some embodiments, the second strap 108 further includes a padded portion. As shown in Figures 8 and 12, the first and second straps 102, 108 have a strap width 180 and a strap thickness 182.
[0027] The backpack 100 can be configured with first and second straps 102 and 108. As shown in Figure 2, the backpack 100 can comprise a central body 114, a first side 120, a second side 122, a front section, and a back section. The central body 114 can comprise a top section 116 and a bottom section 118. The top section 116 can comprise a first mounting opening 152 for receiving the first mounting end 110 of the first strap 102. The first mounting opening 152 can be cut out from the central body 114 so that a plane extending through the first mounting opening 152 can be perpendicular to a plane extending through the central body 114. The bottom section 118 can comprise a second mounting opening 154 for receiving the second mounting end 112 of the first strap 102. The second mounting opening 154 may be cut out from the central body 114 such that a plane extending through the second mounting opening 154 can be perpendicular to a plane extending through the central body 114. In some embodiments, the first and / or second mounting ends 112 of the first strap 102 may be looped through the first and / or second mounting opening 154 and returned to the first strap 102 and secured by stitching. In some embodiments, the central body 114 of the backpack 100 may include a logo or emblem 190. The logo or emblem 190 may be embossed, printed, or formed by cutting out the central body 114. In the illustrated embodiment, the logo 190 is formed by cutting out the central body 114. The first and second sides 120, 122 of the backpack 100 may be configured to detachably receive the second strap 108.
[0028] As shown in Figures 2, 4, and 10-13, the first side 120 and the second side 122 can be inclined downward from the central body 114 toward the back of the pack. In some embodiments, the first and second side 122 can be inclined downward from the central body 114 at equal angles to each other. As shown in Figure 10, the first side 120 can be inclined downward from the central body 114 at a first side angle 160 between 10 and 90 degrees. The second side 122 can be inclined downward from the central body 114 at a second side angle 160 between 10 and 90 degrees. The first side angle 160 and / or the second side angle 162 can be 10-20 degrees, 20-30 degrees, 30-40 degrees, 40-50 degrees, 50-60 degrees, 60-70 degrees, 70-80 degrees, or 80-90 degrees.
[0029] Referring to Figures 3 and 5, the first side portion 120 may comprise a first top corner portion 124, a first bottom corner portion 126, and a first arm portion 132. The first arm portion 132 may comprise a top first arm portion 136 and a bottom first arm portion 138. The first arm portion 132 may be discontinuous such that the space between the top first arm portion 136 and the bottom first arm portion 138 defines a first slit 144. The top first arm portion 136 is connected to and may extend from the first top corner portion 124. The bottom first arm portion 138 is connected to and may extend from the first bottom corner portion 138.
[0030] The second side portion 122 may comprise a second top corner portion 128, a second bottom corner portion 130, and a second arm 134. The second arm 134 may comprise a top second arm portion 140 and a bottom second arm portion 142. The second arm 134 may be discontinuous such that the space between the top second arm portion 140 and the bottom second arm portion 142 defines the second slit 146. The top second arm portion 140 is connected to and may extend from the second top corner portion 128. The bottom second arm portion 142 is connected to and may extend from the second bottom corner portion 130. The first slit 144 and the second slit 146 allow the second strap to engage with or detach from the backpack 100. In other words, the first slit 144 in the first arm 132 and the second slit 146 in the second arm 134 each allow the strap system to be converted between a single-strap configuration and a double-strap configuration.
[0031] The first side portion 120 can define a first side opening 148 configured to receive a second strap 108. The first top corner 124, the first bottom corner 126, the first arm 132, and the central body 114 of the backpack 100 can form the boundary of the first side opening 148. The first arm 132 can define the outer edge of the first side opening 148. The first slit 144 can open into the first side opening 148. The second side portion 122 can define a second side opening 150 configured to receive a second strap 108. The second top corner 128, the second bottom corner 130, the second arm 134, and the central body 114 can form the boundary of the second side opening 150. The second arm 134 can define the outer edge of the second side opening 150, and the second slit 146 can open into the second side opening 150.
[0032] Referring to Figures 3 and 7, the first side opening 148 has a first side opening width 164 and a first side opening height 168. Referring to Figures 3 and 6, the second side opening 150 has a second side opening width 166 and a second side opening height 170. The first side opening width 164 and the second side opening width 166 may be the same width. The first side opening height 168 and the second side opening height 170 may be the same height.
[0033] The first side opening width 164 and the second side opening width 166 are in the range of 20 mm to 30 mm. The first side opening width 164 and the second side opening width 166 can be 20 mm to 22 mm, 22 mm to 24 mm, 24 mm to 26 mm, 26 mm to 28 mm, or 28 mm to 30 mm. In some embodiments, the first side opening width 164 and / or the second side opening width 166 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, or 30 mm. The first side opening width 164 and the second side opening width 166 are greater than the second strap width 180. The first side opening height 168 and the second side opening height 170 are in the range of 2 mm to 8 mm. The first side opening height 168 and the second side opening height 170 can be 2mm to 3mm, 3mm to 4mm, 4mm to 5mm, 5mm to 6mm, 6mm to 7mm, or 7mm to 8mm. In some embodiments, the first side opening height 168 and / or the second side opening height 170 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm.
[0034] Referring to Figures 3 and 6-8, the first side opening 148 and the second side opening 150 are sized to accommodate the second strap 108. The widths 164 and 166 of the first and second side openings are greater than the width 180 of the second strap. The heights 168 and 170 of the first and second side openings are greater than the thickness 182 of the second side strap. The widths 164 and 166 and the heights 168 and 170 of the first and second side openings allow the second strap 108 to fit comfortably within the first and second side openings 148 and 150 and to slide freely through them. In other words, the widths 164, 166 of the first and second side openings and the heights 168, 170 of the first and second side openings have values that allow the second strap 108 to move unobstructed and unrestrained within the first and second side openings 148, 150 in the direction from the first side opening 148 to the second side opening 150. This free movement of the second strap 108 allows the golf bag to self-adjust to the user's posture when the strap system is a double-strap configuration.
[0035] As shown in Figures 6 and 7, the first slit 144 and the second slit 146 have a slit width 172. The slit width 172 can be measured vertically from a plane in contact with the end of the top arm portion 136 or 140 to a plane in contact with the end of the bottom arm portion 138 or 142, respectively. The slit width 172 is in the range of 0.5 mm to 5 mm. The slit width 172 can be 0.5 mm to 0.7 mm, 0.7 mm to 0.9 mm, 0.9 mm to 1.1 mm, 1 mm to 1.5 mm, 1.5 mm to 2 mm, 2 mm to 3 mm, 3 mm to 4 mm, or 4 mm to 5 mm. In some embodiments, the slit width 172 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1.0 mm. The slit width 172 is greater than the second strap thickness 182. The first slit 144 and the second slit 146, respectively, allow for the insertion and removal of the second strap 108 from the first side opening 148 and the second side opening 150.
[0036] As shown in Figures 6 to 9, in some embodiments, the first slit 144 can be located closer to the top 116 than to the bottom 118 of the backpack 100, and the second slit 146 can be located closer to the bottom 118 than to the top 116 of the backpack 100. The top first arm portion 136 can be shorter than the bottom first arm portion 138. The top second arm portion 140 can be longer than the bottom second arm portion 142. The positions of the first slit 144 and the second slit 146, defined by the lengths of the multiple arm portions, affect the backpack 100's ability to hold the second strap 108 without it slipping through when the golf bag has a double strap configuration.
[0037] As shown in Figure 16, in the double-strap configuration, when the golf bag is lifted by grasping the second strap 108, the fabric of the second strap 108 may contract within the first side opening 148 and the second side opening 150. Within the first side opening 148, the second strap 108 can contract towards the first top corner 124 at the top 116 of the pack 100. The position of the first slit 144, which is closer to the top 116 (and the first top corner 124) than to the bottom 118 (and the first bottom corner 126), can prevent the edges of the second strap 108 from slipping through when the second strap 108 is bundled. Within the second side opening 150, the second strap 108 can contract towards the second bottom corner 130 at the bottom 118 of the pack 100. The position of the second slit 146, which is closer to the bottom 118 (and second bottom corner 130) than to the top 116 (and second top corner 128), prevents the edge of the second strap 108 from slipping through when the strap 108 is bundled. Thus, the lengths of the top first arm portion 136, the bottom first arm portion 138, the top second arm portion 140, and the bottom second arm portion 142 prevent the second strap 108 from slipping through the first and second slits 144 and 146. This security helps to keep the second strap 108 loosely in place within the backpack, and as a result, the second strap 108 is slidably connected to the first strap 102.
[0038] Referring to Figure 5, each of the first slit 144 and / or the second slit 146 can be angled with respect to the first arm 132 and / or the second arm 134. In some embodiments, the first slit 144 and / or the second slit 146 can be angled substantially parallel to a reference line 174 drawn from the first top corner 124 of the pack 100 to the second bottom corner 130 of the pack 100. In some embodiments, the first slit 144 and / or the second slit 146 can have any angle suitable for inserting and removing the second strap 108. In some embodiments, the longitudinal axis 178, when viewed from the rear, is defined in the direction from the first side 120 to the second side 122 and is located at the center of the top 116 and bottom 118 of the backpack. The first slit reference line 145, when viewed from the rear, extends parallel to the first slit through it. The second slit reference line 147 extends parallel to the second slit when viewed from the back. The first slit 144 is angled by a first slit angle θ1, measured counterclockwise from the longitudinal axis 178 to the first slit reference line 145. The second slit 146 is angled by a second slit angle θ2, measured counterclockwise from the longitudinal axis 178 to the second slit reference line 147. The first slit angle θ1 can be equal to the second slit angle θ2. In some embodiments, the first slit angle θ1 and / or the second slit angle θ2 have values between 0 and 80 degrees. In some embodiments, the first slit angle θ1 and / or the second slit angle θ2 are 0 to 10 degrees, 10 to 20 degrees, 20 to 30 degrees, 30 to 40 degrees, 40 to 50 degrees, 50 to 60 degrees, 60 to 70 degrees, or 70 to 80 degrees. The angled first slit 144 and second slit 146 help prevent the second strap from unintentionally detaching from the backpack (by slipping out of the first slit 144 and / or second slit 146) in a double-strap configuration, while also allowing for the quick removal of the second strap to convert the strap system to a single-strap configuration. The design of the first and second slits 144 and 146 enables rapid and versatile conversion and configuration of the strap system.
[0039] The first side opening 148 and the second side opening 150 can be configured to detachably receive the second strap 108 of the golf bag. As shown in Figures 7 and 11, the linear path 158 can extend through the openings of the first side 120 and the second side opening 150. In other words, the linear path includes the space directly between the first side opening 148 and the second side opening 150. No part of the backpack 100 intersects with the linear path. The path has a passage width that is the same as the width of the first side opening 164 and the second side opening 166.
[0040] Referring to Figures 4, 5, 7, and 9, in some embodiments, the channel 156 may be cut out of the central body 114. The channel 156 may extend parallel to the linear path 158. In some embodiments, the linear path 158 extends through the channel 156. The channel 156 may extend from the first side opening 148 to the second side opening 150. The channel 156 may have the same width as the first side opening 148 and the second side opening 150. The channel 156 may be cut out or recessed in the plane of the central body 114 such that the plane of the channel 156 is parallel to the plane of the central body 114. The channel 156 may have a certain depth 176. The depth 176 of the channel 156 may be less than the thickness of the central body 114. In some embodiments, the channel depth 176 may be in the range of 0 mm to 3 mm. In some embodiments, the channel depth 176 can be 0mm to 0.5mm, 0.5mm to 1mm, 1mm to 1.5mm, 1.5mm to 2mm, 2mm to 2.5mm, or 2.5mm to 3mm. The opening in the first side 120 of the backpack 100, the second side opening 150, and the channel 156 are configured to allow the second strap 108 to move freely along the linear path 158.
[0041] In a single-strap configuration, the first strap 102 can remain unaffected by the second strap 108. In other words, the second strap 108 can be detached from the backpack 100. The backpack 100 can be held and secured between the first part 104 and the second part 106 of the first strap 102.
[0042] In the double-strap configuration, the second strap 108 can be engaged with the backpack 100. The second strap 108 is cut out of the central body 114 and can extend along a channel 156 and / or linear path 158 bounded by the first side opening 148 and the second side opening 150 of the backpack 100. The second strap 108 is configured to slide along the channel 156 without bending, overlapping, or twisting, and without resistance or tightening, so that it is not fixed in a position relative to the backpack 100 along the linear path 158 between the first side opening 148 and the second side opening 150. The sliding motion of the second strap 108 allows the weight of the golf bag to be automatically distributed (self-adjusted) between both the first and second straps 102 and 108 without the user having to adjust the length of either strap. In the double-strap configuration, the backpack 100 restricts to some extent the movement of the second strap 108 in any direction other than the direction of the channel 156. By holding the second strap 108 adjacent to the first strap 102, the backpack 100 can (1) be carried on both shoulders, and (2) maintain a configuration in which the straps are oriented to evenly distribute the weight of the golf bag.
[0043] In the double-strap configuration, the first strap 102 and the second strap 108 can be positioned perpendicular to each other by the backpack 100. The cross-shaped arrangement of the first strap 102 and the second strap 108 connected by the backpack 100 allows the user to easily position the golf bag on their back, and also allows the user to walk and move without the straps 102 and 108 becoming tangled or moving to undesirable positions.
[0044] As described above, the strap assembly can be used in a single-strap configuration as shown in Figure 14, or in a double-strap configuration as shown in Figure 15. To convert the strap assembly from a single-strap configuration to a double-strap configuration, the second strap 108 is engaged with the backpack 100. Referring to Figure 17, engaging the second strap 108 with the backpack 100 involves inserting the edge of the second strap 108 into the first slit 144 of the first side portion 120 of the backpack 100. The second strap 108 can then be set into the first side opening 148 by passing it completely through the first slit 144, which requires the fabric of the second strap 108 to be temporarily bundled to some extent. The second strap 108 can then be spread out into the first side opening 148, and the first arm 132 can hold the second strap 108 within the first side opening 148. Next, another portion of the second strap 108 can be inserted into the second slit 146 of the second side 122 of the backpack 100. Then, the second strap 108 can be supplied through the second slit 146 completely and secured within the second side opening 150 in a manner similar to the insertion of the second strap 108 into the first side opening 148. The second arm 134 holds the second strap 108 within the second side opening 150. Once the insertion of the second strap 108 into the first and second side openings 148 and 150 is complete, the second strap 108 can be positioned along the linear path 158 and will not experience resistance to movement along the linear path 158.
[0045] To convert the strap assembly from a double-strap configuration to a single-strap configuration, the second strap 108 can be removed by reversing the insertion process described above. To remove the second strap from the first side opening 148 and / or the second side opening 150, the second strap 108 can be pulled laterally through the first slit 144 and / or the second slit 146.
[0046] In some embodiments of the convertible strap system, the second strap 108 can be configured to be completely detachable from the golf bag, thereby allowing the user to set the golf bag in a more secure single-strap configuration. In these embodiments, the second strap 108 can be removed to simplify the bag, lighten the bag, and improve its aesthetics.
[0047] The convertible strap system can provide users with greater versatility in how they carry their golf bags. The convertible strap system can reduce fatigue from carrying golf bags by allowing users to adapt the strap system to their needs. Furthermore, the convertible strap system provides a solution for caddies who wish to carry golf bags by positioning a single strap for each bag on each shoulder. In addition, the convertible strap system is simple and requires no tools for the conversion process between single-strap and double-strap configurations. The method of engaging or detaching the second strap 108 from the backpack 100 is understandable without detailed instructions. All these features make the convertible strap system an effective solution to the technical need for a convertible strap system.
