Description

Technical Field

[0001] This invention belongs to the field of cold chain logistics equipment technology, specifically, it relates to a cold chain logistics turnover kiosk and a cold chain logistics turnover system. Background Technology

[0002] With the continuous development of e-commerce, online shopping has become increasingly popular. Due to limitations in logistics, online shopping currently focuses mostly on consumer goods that are easy to transport and preserve, such as electronics and clothing. Vegetables and fruits, meat, and aquatic products are essential consumer goods in people's daily lives, representing a huge market potential. To meet market demand, fresh produce e-commerce has emerged, referring to the direct sale of fresh products, such as fresh fruits, vegetables, and fresh meat, online using e-commerce methods. Fresh produce e-commerce is developing along with the broader trend of e-commerce development.

[0003] A cold chain logistics box with patent application number CN201811115924.0 includes a support frame, a refrigeration structure, a storage structure, a sealing structure, a limiting structure, a bottom plate, a foam insulation board, a driving structure, and a pressure relief structure. The support frame has a storage structure inside for storing and transporting items, and a pressure relief structure between the storage structure and the support frame for depressurizing the items. The storage structure is connected to the driving structure, and the driving structure is connected to the refrigeration structure inside the support frame for storing refrigerated items. In this invention, the storage structure, in conjunction with the driving structure, drives the refrigeration structure, facilitating quick replacement of the refrigerated items inside the refrigeration structure while preventing direct contact between the refrigerated items and the stored items. The pressure relief structure, located between the storage structure and the support frame, converts the impact force during support frame vibration into a driving force for the pressure relief structure, simultaneously driving the storage structure to slide inside the support frame, promoting air circulation within the storage structure.

[0004] The internal storage space of the aforementioned patent is a whole. When logistics items are placed in the storage space for storage, and other logistics items are frequently put in and taken out, these logistics items will be exposed to the high temperature of the outside air. If the exposure is short, the impact can be ignored. However, when the device is opened many times and for a long time, the logistics items will be exposed to the high temperature environment for a longer period of time, which may cause them to deteriorate and be damaged.

[0005] An existing cold chain logistics box with application number CN202210137051.3 includes a mounting box for storing cold chain pharmaceuticals. The mounting box is equipped with refrigeration equipment, and multiple storage units are installed inside the mounting box, all connected to the refrigeration equipment. These storage units prevent the internal temperature from escaping when the cold chain pharmaceuticals are unloaded at storage nodes, ensuring that the remaining cold chain pharmaceuticals do not experience temperature changes. This cold chain logistics box, unlike existing technologies, allows operators to prevent the internal temperature from escaping when unloading cold chain pharmaceuticals at storage nodes by using the storage units, ensuring that the remaining cold chain pharmaceuticals do not experience temperature changes. Furthermore, the side-opening door, combined with multiple movable shelves, allows for individual removal, facilitating the loading and unloading of cold chain pharmaceuticals.

[0006] The aforementioned patent divides the internal storage space into multiple storage units through a multi-partition structure. Although the logistics items are not affected by the retrieval and placement of other logistics items, this structure greatly reduces the volume occupied by the storage space. At the same time, the storage unit limits the size of the stored items. When the logistics item is larger than the storage unit, it cannot be placed in. If the logistics item is smaller than the storage unit, it will cause space waste and reduce logistics efficiency.

[0007] Therefore, it is necessary to improve upon the shortcomings and defects of existing technologies and provide a cold chain logistics turnover kiosk and cold chain logistics turnover system. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cold chain logistics turnover kiosk and cold chain logistics turnover system that can overcome the above problems or at least partially solve the above problems.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a cold chain logistics turnover pavilion includes a turnover pavilion shell with a cold storage compartment, and also includes a condensate bag pad and a bag pad rewinding shell. An insulated liquid storage tank, a refrigeration unit, a liquid supply device, and a liquid extractor are fixedly installed inside the turnover pavilion shell. The drive end of the refrigeration unit extends into the insulated liquid storage tank. The input end of the liquid supply device is fixedly connected to the output end of the insulated liquid storage tank. The output end of the liquid extractor is fixedly connected to the input end of the insulated liquid storage tank. A liquid delivery pipe is fixedly installed and connected to both the output end of the liquid supply device and the input end of the liquid extractor. The liquid delivery pipe passes through the turnover pavilion shell and extends into the cold storage compartment.

[0010] A storage shaft is rotatably installed inside the bag pad rewinding shell. The front end of the condensing bag pad is fixedly connected to the storage shaft. A liquid guiding groove is provided inside the condensing bag pad. The liquid guiding groove and the heat-insulating liquid storage tank are filled with refrigerant. A bag pad connecting block is fixedly installed at the rear end of the condensing bag pad. The bag pad connecting block is provided with an inlet and an outlet. The inlet and outlet are connected to the liquid guiding groove. Both the inlet and outlet are fixedly connected to the infusion pipe.

[0011] To control the rotation of the storage shaft, preferably, an anti-rotation insert is slidably installed on the side end of the bag pad rewind shell. The anti-rotation insert is inserted into the storage shaft, and an arc-shaped limiting block is fixedly installed at the tail end of the anti-rotation insert. The storage shaft is provided with a groove that matches the arc-shaped limiting block.

[0012] To prevent the anti-rotation insert from rotating with the storage shaft, a shaped slider is fixedly installed on the anti-rotation insert, and the bag pad rewind shell is provided with a shaped notch that matches the shaped slider.

[0013] To enable the storage shaft to rotate automatically, a torsion spring is installed inside the storage shaft. One end of the torsion spring is fixedly connected to the storage shaft, and the other end of the torsion spring is fixedly connected to the bag pad rewinding shell.

[0014] In order to fix the position of the bag pad take-up shell as needed, preferably, a fastener hanging plate is fixedly installed inside the shell of the turnover pavilion, a rotating hanging plate is rotatably installed on the fastener hanging plate, and a fixing hook plate is fixedly installed on the bag pad take-up shell. The fixing hook plate is L-shaped, and the rotating hanging plate is inserted into the gap between the fixing hook plate and the outer wall of the bag pad take-up shell.

[0015] To adjust the height of the bag pad connecting block and the condensate bag pad, preferably, the turnover pavilion shell is provided with multiple adjusting grooves, and the infusion tube is slidably connected to the adjusting grooves.

[0016] To further secure the infusion tubing, the infusion tubing includes a flexible tube, an infusion connector, and a fixing bolt. The fixing bolt is fixedly connected to the flexible tube. The infusion connector passes through the adjusting groove, and the fixing bolt is threaded onto the infusion connector. The fixing bolt abuts against the shell of the turnover pavilion.

[0017] To further secure the bag pad connecting block, a fixing connecting block is fitted between the two infusion tubes connected to the same bag pad connecting block. The fixing connecting block is magnetically fixed to the turnover pavilion shell. The bag pad connecting block is provided with a fixing slot that matches the fixing connecting block, and the bag pad connecting block is provided with a magnetic piece that matches the fixing connecting block.

[0018] To ensure that the refrigerant remains liquid even at sub-zero temperatures, the refrigerant is preferably a calcium chloride solution with a concentration ranging from 20% to 25%.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention provides a cold chain logistics turnover pavilion and cold chain logistics turnover system, which uses condensing bag pads to refrigerate logistics items in layers. Each condensing bag pad refrigerates the logistics items above and below it at low temperatures. The spatial distribution inside the cold storage can be flexibly adjusted according to needs. When logistics items need to be taken out, the refrigerant in the condensing bag pad is re-extracted into the insulated storage tank, so that the refrigerant is always kept at a low temperature. There is no need to re-cool the refrigerant, reducing power consumption. At the same time, when logistics items are taken out, the condensing bag pads and bag pad rewinding shells below do not need to be moved, and the logistics items below are still refrigerated at low temperatures. They are not exposed to the high temperature of the outside air, so the low temperature refrigeration of itself will not be affected by the frequent taking out of other logistics items, thus improving the refrigeration effect of these logistics items.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] Example:

[0040] Reference Figure 1 As shown, a cold chain logistics turnover kiosk includes a turnover kiosk shell 1 with a cold storage compartment 101, and also includes a condensate bag pad 2 and a bag pad rewind shell 3, as shown. Figure 9 As shown, an insulated liquid storage tank 6, a refrigeration unit 10, a liquid supply unit 7, and a liquid extractor 8 are fixedly installed inside the turnover pavilion shell 1. The drive end of the refrigeration unit 10 extends into the insulated liquid storage tank 6. The input end of the liquid supply unit 7 is fixedly connected to the output end of the insulated liquid storage tank 6. The output end of the liquid extractor 8 is fixedly connected to the input end of the insulated liquid storage tank 6. A liquid delivery pipe 9 is fixedly installed and connected to both the output end of the liquid supply unit 7 and the input end of the liquid extractor 8. The liquid delivery pipe 9 passes through the turnover pavilion shell 1 and extends into the cold storage compartment 101.

[0041] A storage shaft 302 is rotatably installed inside the bag rewind housing 3. The front end of the condensate bag pad 2 is fixedly connected to the storage shaft 302. Figure 7 As shown, the condenser bag pad 2 is provided with a liquid guiding groove 201. The liquid guiding groove 201 and the heat-insulating storage tank 6 are filled with refrigerant 13. The rear end of the condenser bag pad 2 is fixedly installed with a bag pad connecting block 4. The bag pad connecting block 4 is provided with a liquid inlet 401 and a liquid outlet 402. The liquid inlet 401 and the liquid outlet 402 are connected to the liquid guiding groove 201. Both the liquid inlet 401 and the liquid outlet 402 are fixedly connected to the infusion pipe 9.

[0042] An anti-rotation insert 11 is slidably installed on the side end of the bag pad take-up shell 3. The anti-rotation insert 11 is inserted into the storage shaft 302. An arc-shaped limiting block 111 is fixedly installed at the tail end of the anti-rotation insert 11. The storage shaft 302 is provided with a groove that matches the arc-shaped limiting block 111. Furthermore, a non-circular slider 112 is fixedly installed on the anti-rotation insert 11. The bag pad take-up shell 3 is provided with a non-circular notch that matches the non-circular slider 112. A torsion spring 303 is installed in the storage shaft 302. One end of the torsion spring 303 is fixedly connected to the storage shaft 302, and the other end of the torsion spring 303 is fixedly connected to the bag pad take-up shell 3.

[0043] like Figure 13 As shown, the condensation bag pad 2 is wound around the storage shaft 302, as... Figure 14 and 15 As shown, when the condenser bag pad 2 is in use and needs to be pulled out of the bag pad retractor 3, the anti-rotation insert 11 is pulled outward, allowing the condenser bag pad 2 to stretch outward and the storage shaft 302 to rotate. Then, the arc-shaped limiting block 111 of the anti-rotation insert 11 is inserted into the slot of the storage shaft 302, preventing the storage shaft 302 from rotating and fixing the portion of the condenser bag pad 2 wound on the storage shaft 302. At this time, the torsion spring 303 will deform. When the refrigerant 13 in the condenser bag pad 2 is extracted and the condenser bag pad 2 needs to be retracted into the bag pad retractor 3, the anti-rotation insert 11 is pulled outward, and the arc-shaped limiting block 111 is not inserted into the storage shaft 302. In order to restore its original shape, the torsion spring 303 drives the storage shaft 302 to rotate, allowing the condensate bag pad 2 to be rewound onto the storage shaft 302. Then, the anti-rotation insert 11 is inserted, allowing the arc-shaped limiting block 111 to be inserted into the matching slot, preventing the storage shaft 302 from rotating. The irregularly shaped slider 112 ensures that the anti-rotation insert 11 can only move relative to the bag pad winding shell 3, and cannot rotate relative to it, so that the anti-rotation insert 11 will not be rotated by the storage shaft 302. When the arc-shaped limiting block 111 is inserted into the matching slot, the irregularly shaped slider 112 and the torsion spring 303 resist each other, fixing the storage shaft 302 and the anti-rotation insert 11.

[0044] from Figure 15As can be seen, there are two arc-shaped limiting blocks 111. The arc-shaped limiting block 111 is cut from a ring. In addition to the inner and outer walls of the ring, the arc-shaped limiting block 111 also has an arc-shaped surface and a straight surface. The slot inside the rotating shaft 302 also has a matching arc-shaped surface and a straight surface.

[0045] When the arc-shaped limiting block 111 is fully inserted into the storage shaft 302, the arc-shaped surface of the arc-shaped limiting block 111 will completely abut against the arc-shaped surface of the slot of the storage shaft 302, and the straight surface of the arc-shaped limiting block 111 will completely abut against the straight surface of the slot of the storage shaft 302. The anti-rotation insert 11 cannot rotate under the action of the irregular slider 112. When the anti-rotation insert 11 is fixed, if the storage shaft 302 wants to rotate under the action of the torsion spring 303, the straight surface of the arc-shaped limiting block 111 will apply a force in the opposite direction to the straight surface of the slot of the storage shaft 302, making it unable to rotate.

[0046] However, when the arc-shaped limiting block 111 is pulled out of the storage shaft 302, and the storage shaft 302 rotates, if the rotation angle is an integer of 180 degrees, the two straight surfaces of the arc-shaped limiting block 111 will remain abutted during the insertion of the storage shaft 302, while the two arc-shaped surfaces will not contact each other until the arc-shaped limiting block 111 is fully inserted into the storage shaft 302, at which point the two arc-shaped surfaces will abut. However, the final rotation angle of the storage shaft 302 is not necessarily an integer of 180 degrees, and the arc-shaped limiting block 111... 1. During the insertion of the storage shaft 302, the two arc-shaped surfaces first come into contact and abut. The arc-shaped limiting block 111 cannot rotate. The arc-shaped surface of the arc-shaped limiting block 111 will exert a pushing force on the arc-shaped surface of the storage shaft 302, causing the storage shaft 302 to rotate slightly. The rotation amplitude is not large and does not affect the length and use of the condensation bag pad 2, but it can shorten the distance between the straight surface of the arc-shaped limiting block 111 and the straight surface of the groove of the storage shaft 302 until the two straight surfaces abut, thus completing the fixation of the storage shaft 302.

[0047] A fastener mounting plate 5 is fixedly installed inside the shell 1 of the turnover pavilion. A rotating mounting plate 501 is rotatably mounted on the fastener mounting plate 5. Figure 5 and Figure 6 As shown, a fixing hook plate 301 is fixedly installed on the bag rewind shell 3. The fixing hook plate 301 is L-shaped. The rotating hanging plate 501 is inserted into the gap between the fixing hook plate 301 and the outer wall of the bag rewind shell 3, as shown. Figure 2 and Figure 3 As shown, different sizes of logistics items require different amounts of space in the cold storage compartment 101. When there are large items, the fixed position of the bag pad reel 3 is adjusted, such as... Figure 4As shown, when the bag rewind shell 3 needs adjustment, the fastener mounting plate 5 is installed on the two inner wall sides of the refrigerator compartment 101, and the rotating mounting plate 501 is inserted into the gap between the fixing hook plate 301 and the outer wall of the bag rewind shell 3 to fix the bag rewind shell 3. When the bag rewind shell 3 does not need adjustment, the fastener mounting plate 5 is fixed in front of the inner wall of the refrigerator compartment 101, and the rotating mounting plate 501 is inserted into the gap between the fixing hook plate 301 and the outer wall of the bag rewind shell 3 to fix the bag rewind shell 3. During the adjustment process, the excess condensate bag pad 2 is rolled into the bag rewind shell 3, and only the external condensate bag pad 2 needs to be filled with refrigerant 13.

[0048] During the process of moving the bag rewind shell 3, firstly, the refrigerant 13 in the condensate bag 2 connected to it is extracted, then the anti-rotation plug 11 is pulled out, the rotating hanging plate 501 is rotated, and the rotating hanging plate 501 is manually adjusted to insert into the gap between the fixed hook plate 301 and the outer wall of the bag rewind shell 3. During the adjustment process, the torsion spring 303 will rotate, and the excess condensate bag 2 will be re-rolled onto the storage shaft 302. Then, the refrigerant 13 is refilled into the liquid guide groove 201 to complete the position adjustment of the condensate bag 2 and the bag rewind shell 3, so that the spatial distribution in the cold storage compartment 101 conforms to the size of the logistics items.

[0049] The turnover pavilion shell 1 is provided with multiple adjusting grooves 102. An infusion tube 9 is slidably connected to the adjusting grooves 102. The infusion tube 9 includes a flexible tube 901, an infusion connector 902, and a fixing bolt 903. The fixing bolt 903 is fixedly connected to the flexible tube 901. The infusion connector 902 passes through the adjusting grooves 102, and the fixing bolt 903 is threaded onto the infusion connector 902. The fixing bolt 903 abuts against the turnover pavilion shell 1. Simultaneously adjusting the distance between two adjacent condensation bag pads 2 can further control the spatial distribution within the cold storage compartment 101. Figure 12 As shown, rotate the fixing bolt 903 to slide the infusion connector 902 in the adjusting groove 102. When the infusion connector 902 slides to the appropriate position, rotate the fixing bolt 903 again to fix the infusion connector 902. Then insert the infusion connector 902 into the inlet 401 and the outlet 402.

[0050] A fixing block 12 is fitted between two infusion tubes 9 connected to the same bag pad connecting block 4. The fixing block 12 is magnetically fixed to the turnover pavilion shell 1. Figure 6 As shown, the bag pad connecting block 4 is provided with a fixing slot 403 that matches the fixing connecting block 12, and the bag pad connecting block 4 is provided with a magnetic piece that matches the fixing connecting block 12, such as Figure 8 and Figure 10As shown, the fixed connecting block 12 is fixedly connected to the infusion tube 9, so that the fixed connecting block 12 is fixedly adsorbed on the turnover pavilion shell 1. Then, the bag pad connecting block 4 is fixed by the magnetic attraction of the fixed connecting block 12. The fixed bag pad connecting block 4 and the fixed bag pad winding shell 3 allow the condensation bag pad 2 to be stretched and tightened, thus completing the fixation of the condensation bag pad 2.

[0051] The refrigerant 13 is a calcium chloride solution with a concentration range of 20% to 25%. The calcium chloride solution is a conventional brine solution, which is simple to prepare and low in cost. The higher the calcium chloride concentration, the lower the freezing point of the calcium chloride solution. When the calcium chloride concentration is 20%, the freezing point of the solution is about -20 degrees Celsius. When the calcium chloride concentration is 25%, the freezing point of the solution is about -30 degrees Celsius. The refrigeration unit 10 only needs the temperature of the refrigerant 13 to be -10 degrees Celsius to freeze and refrigerate the logistics items.

[0052] like Figure 11 The insulated liquid storage tank 6 shown is also equipped with a heat-conducting baffle 601 that slides inside. The heat-conducting baffle 601 divides the insulated liquid storage tank 6 into a liquid storage chamber and a gas storage chamber. Multiple vent pipes 602 are fixedly installed on the insulated liquid storage tank 6, and the vent pipes 602 are connected to the gas storage chamber. The turnover pavilion shell 1 is provided with multiple vent holes 103, and the vent holes 103 are connected to the vent pipes 602. When the turnover pavilion shell 1 is closed and sealed for cold chain transportation, the liquid supply device 7 supplies the insulated liquid. When the refrigerant 13 in the storage chamber of tank 6 is extracted and sent to the condenser bag gasket 2, the liquid level in the storage chamber of the insulated storage tank 6 drops, and the air pressure in the storage chamber decreases. In order to maintain the original air pressure, the heat-conducting baffle 601 will move downward. As the heat-conducting baffle 601 moves downward, the air pressure in the air storage chamber decreases, and air in the refrigerator compartment 101 will be drawn out through the vent 103 and the vent pipe 602, allowing the warmer air in the refrigerator compartment 101 to enter the air storage chamber. Inside, a water vapor filter valve is installed in the vent pipe 602 to prevent water vapor from entering the air storage chamber. The heat-conducting baffle 601 transfers heat to make the gas temperature in the air storage chamber the same as the liquid temperature in the liquid storage chamber. When the turnover pavilion shell 1 is opened and logistics items need to be taken out, the liquid pump 8 re-extracts the refrigerant 13 in the liquid guide tank 201 into the heat-insulated liquid storage tank 6. The liquid level in the liquid storage chamber rises, the gas pressure in the liquid storage chamber increases, the heat-conducting baffle 601 moves upward, and the gas pressure in the air storage chamber increases, allowing the low-temperature gas to slowly discharge from the vent hole 103. When there is no refrigerant 13 in the condensation bag pad 2 and the logistics items cannot be refrigerated at low temperature, the low-temperature gas discharged from the vent hole 103 refrigerates the logistics items at low temperature, reduces the rate at which the temperature of these logistics items rises, and prolongs the time that the logistics items are in a low-temperature state, so that they will not heat up and deteriorate due to exposure to the high temperature of the outside air when the turnover pavilion shell 1 is opened.

[0053] This invention involves placing logistics items inside the turnover kiosk shell 1. After the bottom layer of logistics items is placed, the bottom layer bag retractor 3 is pulled to remove the condenser bag pad 2 from the bag retractor 3. Then, the rotating hanging plate 501 is inserted into the gap between the fixing hook plate 301 and the outer wall of the bag retractor 3 to fix the bag retractor 3. The liquid supply device 7 is activated. Each output port and input port of the liquid supply device 7 and the liquid extractor 8 can be opened or closed individually to fill the bottom layer condenser bag pad 2 with refrigerant 13. Then, logistics items are placed one by one on the bottom layer condenser bag pad 2. The above steps are repeated until all logistics items are placed inside the turnover kiosk shell 1, and the condenser bag pads 2 also layer and cover the logistics items. The placement order of the logistics items is sorted according to the logistics route and destination, with the first item taken out placed on top and the last item taken out placed on the bottom.

[0054] If the height of the logistics item is slightly higher than the distance between the two layers of condensate bag pads 2, the condensate bag pads 2 can be slightly bent and deformed. However, in traditional partitioned structures, when the size of the logistics item is slightly larger than the distance between the partitions, the packaging box or the logistics item itself needs to be bent, which can easily damage the logistics item. In this embodiment, the condensate bag pads 2 are adapted to the logistics item, and the condensate bag pads 2 cause slight deformation to the logistics item, rather than the logistics item being deformed to adapt to the device, thereby ensuring the integrity of the logistics item.

[0055] If the height of the logistics item is much greater than the distance between the two layers of condensate bag pads 2, the distribution of the condensate bag pads 2 can be adjusted by using the aforementioned fastener mounting plate 5, rotating mounting plate 501, and adjusting slide 102, so that the condensate bag pads 2 can be adjusted to adapt to the size of the logistics item.

[0056] During long-distance transportation, when the temperature of the refrigerant 13 in the condenser bag pad 2 rises and cannot be maintained at a low temperature for a long time, the pump 8 periodically extracts part of the refrigerant 13 in the condenser bag pad 2, for example, one-third of the refrigerant 13 in the condenser bag pad 2. This part of the refrigerant 13 enters the insulated storage tank 6, and the refrigeration unit 10 is restarted to allow the refrigerant 13 in the insulated storage tank 6 to reach the preset low temperature state again. Then, the liquid supply unit 7 periodically delivers one-third of the refrigerant 13 to the condenser bag pad 2. After the preset time is reached, the pump 8 and the liquid supply unit 7 extract and supply liquid in stages again to keep the refrigerant 13 in the condenser bag pad 2 at a low temperature.

[0057] Upon arrival at the destination, open the turnover pavilion shell 1, start the liquid extractor 8 to extract all the refrigerant 13 from the condensate bag pad 2 above the target logistics item into the insulated storage tank 6, then move the bag pad retractor 3 to allow the deflated condensate bag pad 2, which is now empty of refrigerant 13, to be retracted back into the bag pad retractor 3, exposing the target logistics item. Remove the item. After the target logistics item is removed, pull the bag pad retractor 3 to fix it back in place, allowing the condensate bag pad 2 to be pulled out of the bag pad retractor 3 again. Start the liquid supply device 7 again to fill the condensate bag pad 2 with low-temperature refrigerant 13 to refrigerate the remaining logistics items.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
