Description

Technical Field

[0001] The present invention relates to the technical field of tennis court construction, and in particular to an intelligent tennis ball collection system. Background Art

[0002] During tennis training, a coach often plays against a learner. Due to the huge disparity in strength, it is often impossible to reach a confrontational state. One round takes an average of 2 seconds. To improve efficiency, a tennis collector is often used to pick up the balls after hitting 100-200 balls. The same is true for practicing with a ball serving machine. However, due to the large tennis court and the high dispersion of tennis balls, the traditional handheld tennis collector has low ball picking efficiency, the physical energy consumption of the ball picker is large, and the time to pick up the ball is more than twice the time of playing, which makes the user's time and energy spent on picking up the ball. For this reason, people have developed a variety of new ball picking robots, but the existing ball picking robots use the point picking principle (single ball sequential picking), and the efficiency is even less than one-third of that of human picking, which is far from meeting the use requirements.

[0003] The inventors found in their research that the tennis ball collection device in the prior art has at least the following disadvantages:

Detailed implementation manners

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. The components of the embodiments of the present invention usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0044] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0045] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, or the orientations or positional relationships in which the products of the present invention are usually placed during use, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated devices or elements must have specific orientations, be constructed and operated in specific orientations, and thus cannot be construed as limitations on the present invention.

[0046] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0047] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0048] In the prior art, tennis balls on the tennis court 001 are generally collected manually or by machine. Whether collected manually or by machine, it is necessary to move back and forth on the tennis court 001 and cover the same area multiple times. The actual area walked during the process of collecting tennis balls is much larger than the area enclosed by the perimeter of the tennis court 001. Therefore, the time for collecting tennis balls is increased, the efficiency of collecting tennis balls is reduced, and there is also a situation of missed picking.

[0049] In view of this, the designer provides an intelligent tennis ball collection system, which can reduce the walking range when collecting tennis balls, reduce the probability of walking in the same area multiple times, thereby saving the time for collecting tennis balls, improving the efficiency of collecting tennis balls, and not easily having the situation of missed picking.

[0050] Please refer to Figure 1It should be noted that the intelligent tennis ball collection system provided in this embodiment can be installed on an existing tennis court 001, or directly integrated into the tennis court 001. The tennis court 001 is roughly in the shape of a rectangular parallelepiped, and has a first length side 011 and a second length side 012 opposite to each other in its width direction, and a first width side 013 and a second width side 014 opposite to each other in its length direction. A middle net 002 is installed in the middle of the length direction of the tennis court 001, and there is a gap between the middle net 002 and the first length side 011 and the second length side 012. The middle net 002 divides the tennis court 001 into two halves. Fences are arranged around the tennis court 001, and the fences enclose the tennis court 001 along the directions of the first length side 011, the first width side 013, the second length side 012, and the second width side 014. In the following embodiments, unless otherwise specified, the width direction of the tennis court 001 may also be referred to as the first preset direction 003 , and the length direction of the tennis court 001 may also be referred to as the second preset direction 004 . The first preset direction 003 and the second preset direction 004 are perpendicular.

[0051] Please refer to Figures 1-10 This embodiment provides an intelligent tennis ball collection system, including a ball sweeping device 100 and a collection device 200, wherein:

[0052] The ball sweeping device 100 includes a first power mechanism 110 and a ball sweeping rod 120. The first power mechanism 110 is used to be installed on the tennis court 001. The first power mechanism 110 is in transmission connection with the ball sweeping rod 120. The first power mechanism 110 is used to drive the ball sweeping rod 120 to slide in a first preset direction 003, so as to use the ball sweeping rod 120 to push the tennis ball on the tennis court 001 to the preset area 005.

[0053] The collecting device 200 includes a second power mechanism 210 and a collecting vehicle 220. The second power mechanism 210 is used to be installed on the tennis court 001. The second power mechanism 210 is connected to the collecting vehicle 220 in a transmission manner. The second power mechanism 210 is used to drive the collecting vehicle 220 to slide along a second preset direction 004 within a preset area 005 so as to automatically collect tennis balls using the collecting vehicle 220. The first preset direction 003 and the second preset direction 004 are perpendicular.

[0054] As described above, the working method of the intelligent tennis ball collection system provided in this embodiment is as follows:

[0055] Please refer to Figure 1 and Figure 10, the sweeping device 100 and the collecting device 200 are both installed on the tennis court 001. The sweeping rods 120 of the sweeping device 100 can be two and respectively correspond to the two halves of the tennis court 001. It is set that, in the initial state, the two sweeping rods 120 are attached to the first length side 011 of the tennis court 001, and the collecting vehicle 220 is located in the preset area 005 and close to the first width side 013 of the tennis court 001. When collecting tennis balls, first, the first power mechanism 110 drives the two sweeping rods 120 to slide along the first preset direction 003 towards the second length side 012 of the tennis court 001. There is a gap between the two sweeping rods 120 for the middle net 002 to pass through. The two sweeping rods 120 push the tennis balls on the tennis court 001 towards the second length side 012 in a sweeping manner. When the two sweeping rods 120 move to the preset position, a preset area 005 is formed between the two sweeping rods 120 and the second length side 012. The preset area 005 is roughly a rectangular area. The width of the preset area 005 is basically equal to the distance between the sweeping rod 120 and the second length side 012, and the length of the preset area 005 is basically equal to the length of the tennis court 001. In this way, the tennis balls on the tennis court 001 are all concentrated in the preset area 005. At the same time, the collecting vehicle 220 is clamped between the sweeping rod 120 and the enclosure, and the width of the collecting vehicle 220 is the same as the width of the preset area 005. Then, keeping the position of the sweeping rod 120 unchanged, the second power mechanism 210 is started. The second power mechanism 210 drives the collecting vehicle 220 to move along the second preset direction 004 towards the second width side 014 of the tennis court 001. During the movement of the collecting vehicle 220, it can automatically collect the tennis balls on the movement path. Since the collecting vehicle 220 covers the width of the preset area 005 when moving along the second preset direction 004, the collecting vehicle 220 does not need to pass through the same area repeatedly, which takes a short time, has a high tennis ball collection efficiency, and is not likely to have the situation of missed picking.

[0056] The following embodiments illustrate the details of the intelligent tennis ball collection system of the present application by way of examples.

[0057] Please refer to Figure 1 , in this embodiment, optionally, the intelligent tennis ball collection system includes a sweeping device 100, a collecting device 200, two first guiding devices 300, a second guiding device 400, and a plurality of shaping members 500. The sweeping device 100, the collecting device 200, the first guiding device 300, and the second guiding device 400 are all used to be installed on the tennis court 001, and the shaping members 500 are connected to the two first guiding devices 300. The sweeping device 100 cooperates with the two first guiding devices 300, and the collecting device 200 cooperates with the second guiding device 400.

[0058] Please refer to Figures 1-6Optionally, the ball sweeping device 100 includes a first power mechanism 110 and two ball sweeping rods 120. The first power mechanism 110 is used to be installed on the tennis court 001. The first power mechanism 110 is connected to the two ball sweeping rods 120 in a transmission manner. The first power mechanism 110 can drive the two ball sweeping rods 120 to slide relative to the tennis court 001 in the first preset direction 003, so as to use the two ball sweeping rods 120 to push the tennis balls on the tennis court 001 to the preset area 005. Among them, the two ball sweeping rods 120 correspond to two half-courts respectively, each ball sweeping rod 120 extends in the second preset direction 004, and the length of each ball sweeping rod 120 is approximately equal to one-half of the length of the tennis court 001. In this way, when the ball sweeping rod 120 slides relative to the tennis court 001 along the first preset direction 003, the tennis balls scattered on the corresponding half-court can be pushed to the set area, thereby reducing the probability of missing.

[0059] It should be understood that using one first power mechanism 110 to cooperate with two sweeping rods 120 simultaneously saves the number of first power mechanisms 110, simplifies the structure, and reduces the manufacturing cost. Obviously, in some embodiments, the two sweeping rods 120 can also be driven by two power mechanisms respectively.

[0060] Optionally, the first power mechanism 110 includes a first motor 111, a first transmission wheel 112 and two first transmission units. The first motor 111 is installed on the tennis court 001, and is basically located in the middle of the first length side 011. The rotating shaft of the first motor 111 is connected to the first transmission wheel 112, and the axis of the first transmission wheel 112 extends along the first preset direction 003. Four wire grooves are provided on the first transmission wheel 112, and the four wire grooves are arranged at intervals in the axial direction of the first transmission wheel 112. For ease of description, in the direction from the first length side 011 to the second length side 012, the four wire grooves are respectively the first wire groove 1121, the second wire groove 1122, the third wire groove 1123 and the fourth wire groove 1124. The two first transmission units are both connected to the first transmission wheel 112. The two first transmission units are distributed in two half-courts and can be respectively connected to the two sweeping rods 120. When the first motor 111 is started, the power is transmitted to the two first transmission units through the first transmission wheel 112, and then the two sweeping rods 120 are driven to slide along the first preset direction 003 through the two first transmission units.

[0061] In order to reduce the processing and manufacturing cost, the structures of the two first transmission units can be set to be the same. In this embodiment, the structure of one first transmission unit is taken as an example for description.

[0062] Please refer to Figure 6, Optionally, the first transmission unit includes a first fixed pulley set and a first power rope set. The first fixed pulley set includes a first single fixed pulley 113, a first double fixed pulley 114, a second single fixed pulley 115, and a second double fixed pulley 116; both the first single fixed pulley 113 and the first double fixed pulley 114 are used to be installed on the court, and the two are arranged at intervals in the first preset direction 003. Both the first single fixed pulley 113 and the first double fixed pulley 114 are close to the center net 002. The first single fixed pulley 113 is located on the side of the first double fixed pulley 114 away from the first motor 111, and there is a distance between the first single fixed pulley 113 and the second length side 012. Similarly, both the second single fixed pulley 115 and the second double fixed pulley 116 are used to be installed on the court, and the two are arranged at intervals in the first preset direction 003. Both the second single fixed pulley 115 and the second double fixed pulley 116 are close to the first width side 013. The second single fixed pulley 115 is located on the side of the second double fixed pulley 116 away from the first motor 111, and there is a distance between the second single fixed pulley 115 and the second length side 012. The first single fixed pulley 113 and the second single fixed pulley 115 are on the same straight line, and this straight line is parallel to the second preset direction 004. When the ball sweeping rod 120 moves to the positions of the first single fixed pulley 113 and the second single fixed pulley 115, the ball sweeping rod 120 is limited by the first single fixed pulley 113 and the second single fixed pulley 115, and the ball sweeping rod 120 cannot move forward, and a preset area 005 is formed between the ball sweeping rod 120 and the second length side 012.

[0063] Meanwhile, the first power rope group includes a first power rope body 117 and a second power rope body 118, and both the first power rope body 117 and the second power rope body 118 can be steel wire ropes, etc. The first power rope body 117 is simultaneously wound around the first single fixed pulley 113, the first double fixed pulleys 114 and the first transmission wheel 112, and is located in the second line groove 1122 on the first transmission wheel 112. It should be understood that in the extension direction of the first power rope body 117, the first double fixed pulleys 114 are located between the first transmission wheel 112 and the first single fixed pulley 113, and the first power rope body 117 is in a bent structure under the action of the first double fixed pulleys 114, so that the first power rope body 117 is connected to the first transmission wheel 112 after bypassing the first double fixed pulleys 114. At the same time, the second power rope body 118 is wound around the second single fixed pulley 115, the second double fixed pulley 116 and the first transmission wheel 112 at the same time, and the second power rope body 118 is located in the first line groove 1121 of the first transmission wheel 112. It should be understood that in the extension direction of the second power rope body 118, the second double fixed pulley 116 is located between the second transmission wheel 212 and the second single fixed pulley 115. Under the action of the second double fixed pulley 116, the second power rope body 118 is in a curved structure, and the second power rope body 118 can bypass the space surrounded by the line area of the tennis court 001, so as not to affect the normal use of the tennis court 001. For example, in this embodiment, the second double fixed pulley 116 is approximately located at the connection position of the first length side 011 and the first width side 013, the second power rope body 118 between the second double fixed pulley 116 and the first transmission wheel 112 extends approximately along the first length side 011, and the power rope body between the second double fixed pulley 116 and the second single fixed pulley 115 extends approximately along the first width side 013. Driven by the first power rope body 117 and the second power rope body 118, the sweeping rod 120 can slide in the first preset direction 003 in a posture parallel to the first length side 011. When the sweeping rod 120 moves from the first length side 011 to the preset position close to the second length side 012, the swept area is approximately a rectangular area, and the preset area 005 formed by the two sweeping rods 120 and the second length side 012 is approximately a rectangular area, which is conducive to the collection vehicle 220 to collect tennis balls.

[0064] It should be understood that the two first transmission units correspond to the sweeping rods 120 of the two halves, respectively, and the two first transmission units include a total of four power rope bodies, which are respectively wound in four wire grooves. That is, the two first power rope bodies 117 of the two first transmission units are respectively located in the second wire groove 1122 and the fourth wire groove 1124, and the two second power rope bodies 118 of the two first transmission units are respectively located in the first wire groove 1121 and the third wire groove 1123. The four power rope bodies are not easy to be tangled and entangled, and the operation is stable.

[0065] It should be noted that both ends of the sweeping rod 120 are respectively connected to the corresponding first power rope body 117 and the second power rope body 118. Specifically, the position where one end of the sweeping rod 120 is connected to the first power rope body 117 is between the first single fixed pulley 113 and the first double fixed pulley 114, and the position where the other end of the sweeping rod 120 is connected to the first power rope body 117 is between the first single fixed pulley 113 and the first double fixed pulley 114. Thus, when the first transmission wheel 112 rotates, the first power rope body 117 and the second power rope body 118 rotate, which can drive the two ends of the sweeping rod 120 to move in the same direction, so that the sweeping rod 120 reciprocally slides along the second preset direction 004.

[0066] In this embodiment, optionally, the two first guiding devices 300 are respectively matched with the two sweeping rods 120. In order to reduce the manufacturing cost, the structures of the two first guiding devices 300 are set to be the same. In this embodiment, in order to avoid redundant narration, the structure of one first guiding device 300 is taken as an example for description.

[0067] Please refer to Figures 7-9 , optionally, the first guiding device 300 includes an outer guide rail 310, an inner guide rail 320, an outer slider 330 and an inner slider 340. Both the outer guide rail 310 and the inner guide rail 320 are used to be installed on the tennis court 001. The inner guide rail 320 is close to the center net 002, and the outer guide rail 310 is located on the side of the inner guide rail 320 away from the center net 002, and the two are arranged in parallel at intervals. Both the outer guide rail 310 and the inner guide rail 320 can be guiding cables, and the tightness of the two can be adjusted as needed. The outer slider 330 is slidably installed on the outer guide rail 310 in the first preset direction 003, and the inner slider 340 is slidably installed on the inner guide rail 320 in the first preset direction 003. Both ends of the sweeping rod 120 are respectively connected to the outer slider 330 and the inner slider 340. In this way, driven by the first power rope body 117 and the second power rope body 118, the sweeping rod 120 can move stably driven by the outer guide rail 310 and the inner guide rail 320, is not prone to deviation, is not prone to dead corners, and is not prone to the situation of missed picking.

[0068] Optionally, the outer slider 330 can be a slip ring. A communicating guiding hole 341 and an avoidance notch 342 are provided on the inner slider 340. The inner guide rail 320 passes through the guiding hole 341, and at least part of the width of the avoidance notch 342 is smaller than the cross-sectional outer contour dimension of the inner guide rail 320, which can prevent the inner guide rail 320 from separating from the inner slider 340 at the avoidance notch 342. For example, in this embodiment, the cross-sectional outer contours of both the inner guide rail 320 and the outer guide rail 310 can be circular, the cross-sectional contour of the guiding hole 341 is circular, and at least part of the width of the avoidance notch 342 is smaller than the diameter of the inner guide rail 320.

[0069] Please refer to Figure 9 , further, the avoidance notch 342 includes a first guiding section 3421, a stabilizing section 3422 and a second guiding section 3423 which are connected in sequence. Both the first guiding section 3421 and the second guiding section 3423 are tapered sections, and the stabilizing section 3422 is a constant-width section. Wherein, the widths of the first guiding section 3421 and the second guiding section 3423 gradually decrease from the corresponding ends towards the middle, that is, the widths at both ends of the avoidance notch 342 are larger and the width in the middle is smaller.

[0070] Optionally, the shaping member 500 can be set as a steel wire rope. The number of the shaping members 500 is set as required. Both ends of each shaping member 500 are respectively connected to two inner guide rails 320 of two first guiding devices 300. A plurality of shaping members 500 are arranged at intervals in the extending direction of the inner guide rails 320. Since the inner guide rails 320 span the tennis court 001 and have a long length, and in order to reduce the influence of the inner guide rails 320 on the tennis court 001, the diameter of the inner guide rails 320 is designed to be small. Thus, the slenderness ratio of the inner guide rails 320 is large and the deflection is large, and there is a situation of bending deformation. The shaping member 500 provides a tensile force for the two inner guide rails 320, reduces the tendency of the inner guide rails 320 to bend away from the net 002, and reduces the probability that the inner guide rails 320 bend into the hitting area, and the influence of the inner guide rails 320 on the hitting area is small.

[0071] At the same time, since the avoidance notch 342 is formed on the inner slider 340, when the inner slider 340 slides relative to the inner guide rail 320, the shaping member 500 can slide in the avoidance notch 342, so as to ensure that the shaping member 500 will not collide and interfere with the inner slider 340. Since both ends of the avoidance notch 342 are tapered sections and the size at the port is large, it is beneficial to guide the shaping member 500 into the avoidance notch 342.

[0072] In this embodiment, optionally, the second power mechanism 210 includes a second motor 211, a second transmission wheel 212, a second fixed pulley group 213 and a second power rope group 214. Both the second motor 211 and the second fixed pulley group 213 are used to be installed on the court and are arranged at intervals in the second preset direction 004. The second motor 211 is close to the first width side 013, and the second fixed pulley group 213 is close to the second width side 014. The second transmission wheel 212 is installed on the rotating shaft of the second motor 211. The second power rope group 214 is wound around the second transmission wheel 212 and the second fixed pulley group 213 at the same time. After the second motor 211 is started, it can drive the second transmission wheel 212 to rotate, so as to drive the second power rope group 214 to rotate by using friction. The collection vehicle 220 is connected to the second power rope group 214.

[0073] It should be understood that the second fixed pulley set 213 may include a fixed pulley, and the second power rope set 214 may include a power rope.

[0074] Please refer to Figure 1 and Figure 4 In this embodiment, optionally, the collection vehicle 220 includes a base body 221, a collection box 222 and a collection wheel 223. The base body 221 is provided with a collection opening 2211, and the base body 221 is connected to the second power rope set 214. The collection box 222 is detachably mounted on the base body 221. The collection box 222 is provided with a collection cavity, and the collection opening 2211 is arranged opposite to the collection cavity. The collection wheel 223 is rotatably mounted on the base body 221 and is located between the collection opening 2211 and the collection cavity. When the second power mechanism 210 drives the base body 221 to slide along the second preset direction 004, the collection box 222 moves together with the base body 221, and the collection wheel 223 contacts the tennis court 001. The collection wheel 223 rotates self-driven under the frictional force. During the rotation of the collection wheel 223, the tennis balls passing by can be pushed into the collection box 222 to complete the collection of the tennis balls.

[0075] It should be understood that in the initial state, the collection vehicle 220 is close to the first width side 013, and the collection opening 2211 faces the second width side 014. Driven by the second power mechanism 210, the collection vehicle 220 slides from the first width side 013 to the second width side 014. The tennis balls enter the base body 221 from the collection opening 2211 and are pushed into the collection box 222 by the collection wheel 223 after contacting the collection wheel 223. Since the collection wheel 223 is located between the collection opening 2211 and the collection box 222, the tennis balls in the collection box 222 are blocked by the collection wheel 223 and are not likely to roll out of the collection box 222.

[0076] In this embodiment, optionally, the second guiding device 400 is used to be mounted on the tennis court 001. The collection vehicle 220 is slidably connected to the second guiding device 400 in the second preset direction 004. The movement of the collection vehicle 220 is guided by the second guiding device 400, and the movement of the collection vehicle 220 is stable and reliable.

[0077] Optionally, the second guiding device 400 includes a side rail 410 and a side slider 420. The side rail 410 is used to be mounted on the tennis court 001 and extends in the second preset direction 004. The side slider 420 is slidably sleeved outside the side rail 410, and the collection vehicle 220 is connected to the side slider 420. The side rail 410 can be set as a steel cable or the like. The side slider 420 can be set as a slip ring or the like.

[0078] In other embodiments, optionally, the intelligent tennis collection system further includes an inclined plate 600. The inclined plate 600 is installed on the second length side 012 and has an inclined surface that causes the tennis balls to roll toward the first length side 011. The collection vehicle 220 is located at the lower side of the inclined surface. When the sweeping rod 120 moves to a set position driven by the first power mechanism 110, a preset area 005 is defined between the sweeping rod 120 and the lower side of the inclined surface. Due to the design of the inclined plate 600, the tennis balls can automatically roll into the preset area 005, which is conducive to tennis collection.

[0079] In other embodiments, optionally, the intelligent tennis collection system further includes a solar power generation device. The solar power generation device is electrically connected to each electrical device and can provide power for each electrical device, reducing energy consumption and operating costs.

[0080] The working mode of the intelligent tennis collection system provided in this embodiment is as follows:

[0081] In the initial state, both sweeping rods 120 are close to the first length side 011 of the tennis court 001, and the collection vehicle 220 is close to the first width side 013 of the tennis court 001. When tennis balls need to be collected, the first power mechanism 110 is started. The first motor 111 drives the first transmission wheel 112 to rotate. The two first power rope bodies 117 and the two second power rope bodies 118 cooperate to drive the two sweeping rods 120 to slide along the first preset direction 003 toward the second length side 012. Each sweeping rod 120 slides under the guidance of the inner guide rail 320 and the outer guide rail 310 and can translate in a posture parallel to the length direction of the tennis court 001, thereby pushing the tennis balls on the tennis court 001. When the sweeping rod 120 moves to the set position, the two sweeping rods 120 and the enclosure on the second length side 012 of the tennis court 001 cooperate to form a preset area 005, and the tennis balls are concentrated in the preset area 005. Then, the second power mechanism 210 is started. The second motor 211 drives the second transmission wheel 212 to rotate, and the second transmission wheel 212 drives the second power rope group 214 to rotate, thereby driving the collection vehicle 220 to slide toward the second width side 014. When the collection vehicle 220 slides, it can collect the tennis balls on the path into the collection box 222. Since the width of the collection vehicle 220 is the same as the width of the preset area 005, when the collection vehicle 220 slides along the second preset direction 004, it can contact the tennis balls distributed in the width direction of the preset area 005. The collection vehicle 220 only needs to slide along the second preset direction 004 and does not need to move in the width direction of the preset area 005. The area where the collection vehicle 220 travels again is small, the time for collecting tennis balls is short, and the efficiency is high. When the tennis collection is completed, the first motor 111 moves in the reverse direction, and the two sweeping rods 120 return to the initial position. The second motor 211 moves in the reverse direction, and the collection vehicle 220 returns to the initial position.

[0082] The intelligent tennis ball collection system provided in this embodiment has a high degree of automation and high efficiency in tennis ball collection.

[0083] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
