Description

Technical Field

[0001] This invention relates to the field of enclosure technology, and in particular to an impact-resistant enclosure buffer protection system. Background Technology

[0002] With the rapid development of modern logistics and precision manufacturing technology, the requirements for cushioning and protection of various high-value items, such as precision instruments, electronic equipment, medical devices and aerospace components, are becoming increasingly stringent during transportation. This necessitates the use of protective cases. In particular, for medical devices, the safety of the medical device determines the accuracy of the instrument's testing.

[0003] Currently, Chinese patent application number CN202410591888.4 discloses a box-type field surgical module, including a box-shaped operating bed box, an anesthesia monitoring box, a multi-functional surgical treatment box, and an accessory box. The operating bed box transforms from a box shape to a bed shape when its two opposite side panels are unfolded. The anesthesia monitoring box includes a first box body and a first lid fastened to the first box body; when the first box body is stacked on top of the first lid, it transforms from a box shape to an equipment stand. The first box body carries anesthesia monitoring medical equipment. The multi-functional surgical treatment box includes a second box body and a second lid fastened to the second box body; when the second box body is stacked on top of the second lid, it transforms from a box shape to an equipment stand. The second box body carries surgical treatment medical equipment. The accessory box contains a multi-functional support, a shadowless lamp, and an ultraviolet disinfection lamp. It can be seen that the box body only provides simple fixation for the medical devices; when subjected to impact, the vibration force is still transmitted to the instruments inside the box.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered: Insufficient protection and limited opening methods: Existing instrument storage cases primarily focus on enhancing the impact resistance of the case itself, rather than developing impact resistance for the instruments inside. As a result, while the case may withstand impact without damage, the force is transmitted to the instruments through the connection between the case and the instruments, causing severe vibrations or even collisions with the inner wall of the case, leading to instrument damage. Secondly, it has been found that the opening direction of the lid is fixed, and opening and closing requires adjusting the fixing structures (locks, etc.) on the case. Therefore, opening the case not only requires time to observe the orientation of the lid, but also requires rotating the case and opening the fixing structures if the position is incorrect. Furthermore, when closing the case, it is necessary to ensure that the fixing structures are closed, which seriously affects the convenience of use. Therefore, we propose an impact-resistant case buffer protection system. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an impact-resistant enclosure buffer protection system, which solves the technical problems of insufficient protection and limited opening methods in existing instrument storage boxes during use.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An impact-resistant enclosure buffer protection system, the protection system comprising: Box; The lid is located on the top of the enclosure, and a limit component is installed on the side of the lid facing the enclosure to restrict the equipment inside the enclosure. The limiting component includes a combination plate connected to the box cover, and a number of slidable extension rods are inserted into the combination plate, the extension rods being arranged in a matrix on the combination plate; When the lid is connected to the body, the extension rod at the bottom of the lid extends into the body under the action of gravity and fits against the equipment stored inside the body.

[0007] Preferably, the combined plate includes a bottom plate and a top plate corresponding to each other, and a movable clamping plate is inserted between the bottom plate and the top plate; The top of the movable clamping plate is provided with a strip-shaped through hole, and the limiting protrusion on the inner wall of the strip-shaped through hole corresponds to the slot on the outer wall of the extension rod. When the movable clamp slides, the limiting protrusion on the inner wall of the strip-shaped through hole and the slot on the outer wall of the extension rod interlock.

[0008] Preferably, a lever is inserted into the top of the box cover, and the lever passes through the box cover and is connected to the movable clamping plate, so that the movable clamping plate can be moved by the lever.

[0009] Preferably, the box body and the box cover are connected by a connecting hook. The connecting hook includes a mounting base connected to the box body, and an extension frame is connected to the outside of the mounting base by a torsion spring. When the box body and the box cover are in contact, the hook on the extension frame is fastened to the docking post on the outside of the box cover.

[0010] Preferably, an adjustment component is embedded in the bottom of the lid, and the adjustment component surrounds the outside of the limiting component, so as to switch the opening mode of the lid. The adjustment component includes four driving components, which are arranged in pairs. The two pairs of driving components are interwoven with each other. The driving components are connected to the driven components inside the box cover, and the driven components drive the docking column to move. When the drive unit moves, it can cause the docking posts and hooks in three directions of the box cover to separate.

[0011] Preferably, the driving component includes two parallel linkage gear plates, and a stop bar is connected between the ends of the two linkage gear plates; The connecting toothed plate is connected to the rotating rod on the box cover, and the teeth on the connecting toothed plate correspond to the driven gear. When the rotating rod rotates, it can drive the driven gear on the connecting toothed plate to rotate, providing torque to the driven component. The stop bar corresponds to the linkage at the bottom of the driven member, and when the stop bar moves, it squeezes the extrusion plate.

[0012] Preferably, the end of the rotating rod is connected to a lever head, and the lever head engages with the locking teeth at the end of the connecting tooth plate, so that the connecting tooth plate can be moved horizontally by rotating the rotating rod.

[0013] Preferably, the two connecting gear plates in the same set of driving components are in contact with each other, and the locking teeth on them are located on both sides of the driven gear, and neither of them meshes with the driven gear; The driven gear is located on the path of the moving gear plate.

[0014] Preferably, the driven member includes an elliptical extrusion head, and each side of the extrusion head is provided with an opening and closing plate. The opening and closing plate is connected to the docking post on the box cover. When the extrusion head rotates, the opening and closing plates on both sides drive the docking post to separate from each other. The opening and closing plate is connected to the box cover by a spring, and the spring is always in a compressed state. The spring's thrust on the opening and closing plate is directed towards the pressing head.

[0015] Preferably, the linkage includes two linkage pins that are hinged to each other, and a pressing plate is connected at the hinge, which is connected to the stop bar. The two connecting pins are respectively connected to the opening and closing plates on both sides of the extrusion head. When the extrusion plate moves, it drives the opening and closing plates connected to the connecting pins to perform opening and closing movements.

[0016] (III) Beneficial Effects 1. Because a matrix arrangement of extension rods is used as the structure for the contact between the box cover and the instrument, the extension rods are telescopic. After the extension rods touch the instrument, they are limited by a movable clamp, so that the extension rods form corresponding recesses along the shape and position of the instrument. This adapts to the shape requirements of various instruments, thus effectively solving the problem of insufficient protection in existing instrument storage boxes during use. It also fills the gap between the instrument and the box to clamp and limit the instrument. In addition, it can be adaptively adjusted according to the shape of the stored instrument, improving the applicability of the device.

[0017] 2. By using a rotating rod as a pivot, its rotation drives the driving component to transmit kinetic energy to the driven component connected to it, i.e., to transmit torque to the driven components on both sides of the rotating rod, causing the pressing head on it to rotate. This causes the opening and closing plates located on both sides of the pressing head to be pressed open, thus opening them. At this time, the "locks" located on both sides of the rotating rod are already open. Furthermore, since the stop bar on the linkage plate is connected to the linkage component on the side where the rotating rod is located, the torque of the rotating rod can be synchronously transmitted to the "lock" on the same side of the instrument when the rotating rod rotates, thereby opening the "lock" on the same side of the rotating rod. At this time, only the "lock" opposite to the rotating rod is not opened, so it can be rotated around this axis. Therefore, it effectively solves the technical problem of the limited opening method of existing instrument storage boxes during use, and thus achieves the purpose of freely switching the opening method without considering other reinforcement structures on the box body. At the same time, it can also maintain the stability of the box body in the closed state, thereby improving the applicability and safety of the box body. Attached Figure Description

[0021] This application provides an impact-resistant box buffer protection system, which effectively solves the technical problems of insufficient protection and limited opening methods in existing instrument storage boxes. By using a matrix-arranged extension rod as the structure for the box cover to contact the instrument, and utilizing the telescopic function of the extension rod, a movable clamping plate limits the extension rod after it touches the instrument, so that the extension rod forms a corresponding recess along the shape and position of the instrument. This adapts to the shape requirements of various instruments, thereby filling the gap between the instrument and the box to clamp and limit the instrument. In addition, it can be adaptively adjusted according to the shape of the stored instrument, improving the applicability of the device. Secondly, because a rotating rod is used as a pivot, when it rotates, it drives the driving component to transmit kinetic energy to the driven component connected to it, that is, to transmit torque to the driven components on both sides of the rotating rod, causing the pressing head on it to rotate, thereby pressing the opening and closing plates located on both sides of the pressing head and opening them. At this time, the "locks" located on both sides of the rotating rod have been opened. Furthermore, since the stop bar on the linkage plate is connected to the linkage component on the side where the rotating rod is located, when the rotating rod rotates, it can synchronously transmit the torque of the rotating rod to the "lock" on the same side of the instrument, thereby opening the "lock" on the same side of the rotating rod. At this time, only the "lock" opposite to the rotating rod is not opened, so it can be rotated around this axis, thus achieving the purpose of freely switching the opening mode without considering other reinforcement structures on the box, while maintaining the stability of the box in the closed state, thereby improving the applicability and safety of the box. Example

[0022] The technical solution in this application embodiment addresses the problem of insufficient protection in existing instrument storage boxes during use. The overall approach is as follows: To address the problems existing in the prior art, this invention provides an impact-resistant enclosure buffer protection system. This system primarily optimizes the fixed state of instruments during storage to improve the safety and stability of the instrument storage room. The system mainly consists of two parts: one part is for "reinforcing" the instruments; the other part optimizes the opening method of the enclosure lid 2. The specific structure is as follows: Traditionally, when storing instruments, the instrument in case 1 is simply placed inside, without direct connection between the instrument and case 1. These are two independent parts, like putting coins in a piggy bank. When there is no shaking, they are relatively stationary, and case 1 provides some protection by covering the instrument. However, in the event of a collision, case 1 itself will shake violently, and the instrument inside will shake even more. Because the instrument is not fixed to case 1, it can move within the case and collide with the inner wall of case 1. Current improvements only fix the instrument to the bottom of case 1 using bolts or other reinforcing parts to form a "unit." However, this method still has a drawback: the top of the instrument. Since only the bottom of the instrument is connected to case 1, the top is suspended, causing it to shake during vibrations. To solve this problem, we have improved the top of case 1, i.e., the lid 2, to reinforce the instrument. The specific improvements are as follows: A set of limiting components 4 is installed on the side of the cover 2 facing the enclosure 1 to limit the movement of equipment inside the enclosure 1. The limiting components 4 mainly consist of two parts: a combination plate connected to the cover 2; and several sets of extension rods 45 inserted into the combination plate, such as... Figure 3 As shown, all the extension rods 45 are arranged in a matrix on the assembly plate. This allows the extension rods 45 at the bottom of the lid 2 to extend into the housing 1 under gravity when the lid 2 is connected to the housing 1. Since the extension rods 45 are blocked by the instrument, they cannot move downwards, thus locking their position and ensuring a close fit with the equipment stored inside the housing 1. Furthermore, because the extension rods 45 are blocked by the instrument's outer shell, the recesses formed by the extension rods 45 conform to the shape of the instrument's outer shell, resulting in a better fit.

[0023] A spherical silicone head 46 is also connected to the end of the extension rod 45. This not only prevents the extension rod 45 from making hard contact with the instrument, but also cushions the instrument when it vibrates. This provides excellent protection.

[0024] However, a defect was still discovered during use: the extension rod 45 only moves in the direction of the instrument under the influence of gravity. Therefore, when the housing 1 is tilted, the direction of gravity on the extension rod 45 also shifts, causing the extension rod 45 to retract. To solve this problem, we adjusted the connection structure of the extension rod 45, specifically the assembly plate. The assembly plate is divided into three interlocking plate structures: from top to bottom, a top plate 42, a movable clamping plate 43, and a bottom plate 41. The bottom plate 41 and top plate 42 are integrally formed and connected to the housing cover 2, mainly serving to restrict the position of the extension rod 45. The movable clamping plate 43, located between the two, can slide freely, such as... Figure 4 - Figure 6 As shown.

[0025] like Figure 5 As shown, a circular hole is provided on the base plate 41 to accommodate the silicone head 46 on the extension rod 45; a square hole corresponding to the circular hole is also provided on the top plate 42, and the shape of the square hole is consistent with that of the extension rod 45, so that the extension rod 45 can extend and retract along the square hole.

[0026] A strip-shaped through hole is provided on the movable clamping plate 43 between the two, and multiple limiting protrusions 48 are provided on the inner wall of the strip-shaped through hole, such as... Figure 5 As shown, the limiting protrusion 48 can be inserted into the slot on the outer wall of the extension rod 45. This allows the extension rod 45 to be moved into position, and the sliding movable clamp 43 causes the strip-shaped through hole on it to move. During this movement, the limiting protrusion 48 on the inner wall of the strip-shaped through hole inserts into the slot on the outer wall of the extension rod 45, thus "locking" the extension rod 45 and maintaining its position and state. Figure 6 As shown, one end of the movable clamp 43 extends outside the bottom plate 41 and the top plate 42, and a lever 44 is connected to that end. When the combined plate is connected to the lid 2, the lever 44 passes through a hole in the lid 2, so that the user can lock and unlock the extension rod 45 from the outside of the lid 2 by moving the lever 44.

[0027] In addition, to prevent the extension rod 45 from moving out of the assembly plate, a disc-shaped baffle 47 is connected to the other end of the extension rod 45. The baffle 47 needs to be larger than the square hole on the top plate 42 so that the extension rod 45 cannot be moved out of the assembly plate.

[0028] In the specific implementation process, the instrument is first installed at the bottom of the housing 1. After that, the housing cover 2 is placed on the housing 1. At this time, the extension rod 45 on the housing cover 2 will move towards the instrument under its own weight until it stops touching the outer shell of the instrument. Then, by moving the lever 44 on the housing cover 2, the movable clamping plate 43 located between the top plate 42 and the bottom plate 41 is moved. When the movable clamping plate 43 moves, the strip-shaped through hole on it moves synchronously, while the extension rod 45 cannot move due to the square hole. A relative motion state is formed between the movable clamping plate 43 and the extension rod 45. Therefore, during the movement of the movable clamping plate 43, the limiting protrusion 48 on the inner wall of the strip-shaped through hole is inserted into the slot on the outer wall of the extension rod 45, thereby "locking" the extension rod 45 and maintaining the position and state of the extension rod 45. Moreover, since the extension rod 45 is blocked by the outer shell of the instrument, the recess formed by the extension rod 45 is consistent with the shape of the outer shell of the instrument, so it can better fit the instrument. In addition, by also setting the same limiting component 4 on the top of the housing 1, a clamping structure that fits against the outer wall of the instrument can be formed simultaneously. Example

[0029] Based on Example 1, the embodiments of this application aim to solve the technical problem of the limited opening method of existing instrument storage boxes during use. The overall idea is as follows: Traditional cases (case body 1) have a fixed opening mechanism due to manufacturing limitations. Specifically, the hinge between case body 1 and lid 2 is fixed in position during production, allowing lid 2 to be opened only from the side opposite the hinge's position. In actual use, because the opening position of lid 2 is fixed, it's necessary to observe which side of case body 1 can be opened to ensure it faces the user when placing or carrying it. Existing solutions involve replacing the hinge with a movable connection structure. While this allows adjustment of the lid 2's opening direction, it requires adjustment each time, and the opening position of lid 2 still needs to be determined during use, severely impacting ease of use and adaptability. Our newly developed lid 2 allows direct selection of the opening position as needed, requiring no adjustment; it can be opened using the traditional method, making it simple and quick. The specific structure is as follows: like Figure 7As shown, the connection structure (connecting hook 3) between the box body 1 and the box cover 2 is installed on the box body 1, with two hooks installed on the same side of the box body 1. When the box body 1 is opened, it serves as the connection structure between the box body 1 and the box cover 2. The connecting hook 3 mainly consists of two parts: one part is a mounting base 31 connected to the box body 1, and the outer side of the mounting base 31 is connected to a fitting frame 34 via a torsion spring, so that the mounting base 31 and the fitting frame 34 are like a "clamp"; the other part is an extension frame 32 connected to the fitting frame 34. The two are fixedly connected, and the end of the extension frame 32 is connected to a hook-shaped hook 33. Under the traction of the torsion spring, the extension frame 32 moves towards the position of the box body 1, so that the extension frame 32 fits against the outer wall of the box body 1. When the box body 1 and the box cover 2 are fitted together, the hook 33 on the extension frame 32 is engaged with the docking post 524 on the outer side of the box cover 2. Therefore, the box body 1 and the box cover 2 can be connected together, and since the box body 1 is equipped with connecting hooks 3 on all four sides, the box cover 2 can be stably fixed on the box body 1.

[0030] When closing, simply place the lid 2 onto the box body 1 and press it down. During the pressing process, the mating post 524 on the lid 2 presses against the hook 33, as... Figure 7 As shown, at this time, the hook 33 unfolds outward under the pressure of the docking post 524. When the box cover 2 and the box body 1 are closed, the opening of the hook 33 corresponds to the hook 33, and the hook 33 hooks the docking post 524 under the action of the torsion spring.

[0031] Based on the above structure (the connecting hook 3 between the box body 1 and the box cover 2), the connection between the box cover 2 and the box body 1 can be released simply by pulling the docking post 524 out of the hook 33. Following this idea, we installed an adjustment component 5 inside the box cover 2 to control the retraction and expansion of the docking post 524. To avoid affecting the limiting component 4, the adjustment component 5 is designed at the edge of the box cover 2, using it to switch the opening method of the box cover 2, such as... Figure 3 As shown.

[0032] Adjustment component 5 includes four drive components 51 (corresponding to the four sides of housing 1 respectively), such as Figure 8 As shown, they are arranged in pairs, and the two groups of drive components 51 are interwoven, as follows: Figure 9 As shown. When the lid 2 is opened, the user's hand is released from the drive component 51, providing power for the drive component 51. To transmit the driving force of the drive component 51 to the docking post 524, a "bridge" needs to be established between the drive component 51 and the docking post 524. That is, a driven component 52 is connected between the drive component 51 and the docking post 524, which drives the docking post 524 to move, such as... Figure 14 and Figure 15 As shown.

[0033] To enable the opening of the box cover 2, it is necessary to simultaneously drive the docking posts 524 at three orientations of the box cover 2 to separate from the hooks 33 when the driving member 51 moves. The details are as follows: First, the driving member 51, as shown in Figure 10 , Figure 14 and Figure 15 , comprises two interlocking toothed plates 511 arranged in parallel with each other, and a blocking strip 512 is further connected between the ends of the two interlocking toothed plates 511, forming a "C"-shaped structure that enables the three components to move in conjunction.

[0034] To enable the above structure to move, the interlocking toothed plates 511 are connected to the rotating rod 513 on the box cover 2, as shown in the enlarged view of the middle-lower part in Figure 1 . The rotating rod 513 is provided with a rectangular grip rod, so that when a user opens the box cover 2, the user's hand presses on the grip rod to flip it upward, thereby providing torque to the rotating rod 513. To transmit the torque to the interlocking toothed plates 511, a shifting head 514 is connected to the end of the rotating rod 513, and the shifting head 514 is engaged with the engaging teeth at the end of the interlocking toothed plate 511, so that the rotation of the rotating rod 513 can drive the interlocking toothed plate 511 to translate, providing power therefor.

[0035] When the interlocking toothed plates 511 move, since the engaging teeth on the interlocking toothed plates 511 correspond to the driven gear 515, the interlocking toothed plates 511 can drive the driven gear 515 thereon to rotate, and then the torque is transmitted to the driven member 52 via the driven gear 515.

[0036] In addition, to prevent the two interlaced interlocking toothed plates 511 from interfering with each other, the engaging teeth thereon are respectively located on two sides of the driven gear 515, neither engaging with the driven gear 515, as shown in Figure 10 . At this time, the driven gear 515 is in an independent state, the rotation of the driven gear 515 is not affected by the engaging teeth on the interlocking toothed plates 511, and the driven gear 515 is located on the moving path of the interlocking toothed plates 511, so that the movement of either interlocking toothed plate 511 can drive the driven gear 515 to rotate, without affecting or being affected by the other interlocking toothed plate 511, which avoids the situation that the driven gear 515 is simultaneously connected with the two interlocking toothed plates 511, thereby ensuring the rotation stability of the driven gear 515.

[0037] Second, the driven member 52, as shown in Figure 11As shown, it includes an elliptical extrusion head 522, and each side of the extrusion head 522 is provided with an opening and closing plate 523. The opening and closing plate 523 is connected to the docking post 524 on the cover 2. So when the extrusion head 522 rotates, the opening and closing plates 523 on both sides and the docking post 524 connected to them separate synchronously. In order to improve the stability of the rotation of the extrusion head 522, two corresponding rollers are installed on the extrusion head 522. In this way, during the rotation of the extrusion head 522, the rollers on the extrusion head 522 roll in contact with the opening and closing plate 523 instead of rubbing against each other.

[0038] Furthermore, to allow the opening / closing plate 523 to reset, a spring is installed between the opening / closing plate 523 and the cover 2. This spring is always compressed, so the spring force pushes the opening / closing plate 523 towards the pressing head 522, thus closing the plate and resetting the docking post 524. This unlocks the connecting hook 3 corresponding to the linkage toothed plate 511. Unlocking refers to the separation of the docking post 524 from the hook 33; conversely, locking refers to the hook 33 being engaged with the docking post 524.

[0039] Third, the linkage 53, such as Figure 12 and Figure 13 As shown, it includes two connecting pins 531, and the connecting pins 531 are connected to the rotating head 534 via push rods 533. The rotating head 534 on the two connecting pins 531 is hinged to the same pressing plate 532, and the pressing plate 532 is connected to the stop bar 512, as shown. Figure 13 As shown. The two connecting pins 531 are respectively connected to the opening and closing plates 523 on both sides of the extrusion head 522, as... Figure 11 As shown, when the pressing plate 532 moves, it drives the opening and closing plate 523 connected to the linkage pin 531 to perform an opening and closing motion. This capability is used to unlock the connecting hook 3 on the same side as the rotating rod 513.

[0040] The two corresponding mating posts 524 are respectively provided with a pin and a slot. When the two mating posts 524 are mated together, the pin on them is inserted into the slot, thereby improving the stability of the connection between the two and preventing deformation under force.

[0041] In the specific implementation process, the first step is for the user to press their hand on the notch below the lid 2 according to their needs, making contact with the handle in the notch, and then lift it upwards. At this time, the handle, under the pushing force of the user's hand, drives the rotating rod 513 to rotate upwards, thus providing torque to the rotating rod 513. Since the end of the rotating rod 513 is connected to the actuating head 514, and the actuating head 514 engages with the locking teeth at the end of the connecting tooth plate 511, when the rotating rod 513 rotates, it can drive the connecting tooth plate 511 to translate, such as... Figure 14As shown in the enlarged view of the upper middle part, the stop bar 512 connected to the linkage toothed plate 511 also moves synchronously.

[0042] In the second step, since the teeth on the connecting gear plate 511 correspond to the driven gear 515, the connecting gear plate 511 can drive the driven gear 515 to rotate. The driven gear 515 is connected to the extrusion head 522 in the driven member 52 via the connecting rod 521. Each side of the extrusion head 522 has an opening and closing plate 523. Therefore, when the extrusion head 522 rotates, the opening and closing plates 523 on both sides cause the docking posts 524 to separate from each other. At this time, the docking posts 524 on the same side as the connecting gear plate 511 open, and the hooks 33 connected to the docking posts 524 cannot connect to them. Figure 15 The enlarged view below shows the unlocking of the connecting hooks 3 on both sides of the rotating rod 513.

[0043] Thirdly, during the movement of the connecting toothed plate 511, the stop bar 512 connected to it moves in the direction of the rotating rod 513 and presses the pressing plate 532 on that side, causing it to move. Since the pressing plate 532 is hinged to the two connecting pins 531, when the pressing plate 532 is pressed, it will push the two connecting pins 531 outwards. Figure 12 As shown. This opens the opening and closing plate 523 on the same side as the rotating rod 513, and the connecting hook 3 on the same side unlocks the mechanism.

[0044] At this point, the lid 2 is connected to the connecting hook 3 on the box body 1 only by the docking post 524 on the side away from the rotating rod 513. Therefore, the lid 2 can be rotated open using this as an axis. Similarly, pressing the rotating rod 513 on one side will unlock the connecting hooks 3 on both sides and the same side. When it is necessary to open it completely, the rotating rods 513 on the adjacent sides can be pressed simultaneously to unlock the connecting hooks 3 on all four sides of the lid 2. Figure 16 As shown.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
