Description

Technical Field

[0001] The present invention relates to the technical field of laser line projectors, and specifically to a laser line projector for surveying and mapping. Background Art

[0002] For the battery pack of the laser line projector currently used in the market, during the connection with the host, there are problems such as insecure installation and easy falling. There is no device for preventing falling and easy disassembly, or there is a limiting device for the battery pack, but the mechanism is complex and inconvenient to use, affecting the overall experience of the user.

[0003] The plumb bob assembly inside the laser line projector is a core component, which swings through two mutually perpendicular shafts with bearings. This structure ensures that the plumb bob can swing freely back and forth and left and right and always remain in a vertical state. However, it is precisely such a structural setting that once it falls and the plumb bob assembly shakes and impacts, it will cause damage to the internal components of the laser line projector. Therefore, we introduce a laser line projector for surveying and mapping. Summary of the Invention

[0004] The purpose of the present invention is to provide a laser line projector for surveying and mapping to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A laser line projector for surveying and mapping, including an upper housing and a battery pack. After the battery pack is snapped downward into the installation groove at the rear of the upper housing, the output conductive sheet at the inner bottom of the battery pack is inserted and connected to the power-on conductive sheet at the bottom of the installation groove, and the limit button assembly at the top of the installation groove pops out and is stuck on the top of the battery pack;

[0006] A base is fixed at the bottom of the inner cavity of the upper housing. An annular end cover is fixed at the upper end of the base. A plumb bob assembly is installed on the bracket assembly at the upper end of the annular end cover through a cross-axis swing frame, and the cross-axis swing frame enables the plumb bob assembly to swing back and forth and left and right;

[0007] The base includes a bottom cylinder fixed at the bottom of the inner cavity of the upper housing and a ring-shaped seat connected to the outer side of the top of the bottom cylinder. A ring-shaped rotating seat is provided in the ring-shaped groove on the ring-shaped seat, and buffer clamping components are provided in the reserved grooves equidistantly arranged on the inner side of the ring-shaped groove. The inner ends of the buffer clamping components extend into the ring-shaped seat, and the outer ends of the buffer clamping components abut against the corresponding inclined planes on the inner side of the ring-shaped rotating seat;

[0008] A sliding switch is slidably connected to the side of the upper housing. A conductive component extending into the inner cavity of the upper housing is provided inside the sliding switch. The connecting column at the upper end of the ring-shaped rotating seat extends out through the arc-shaped groove on the annular end cover and is inserted into the U-shaped seat of the conductive component;

[0010] A circular conductive sheet is electrically connected to the corresponding energized conductive sheet through a wire, and another circular conductive sheet is electrically connected to the corresponding laser lamp group on the weight assembly through a wire;

[0011] When the sliding switch is pushed forward, the square conductive sheet on the conductive assembly no longer contacts the corresponding circular conductive sheet, and the battery pack no longer supplies power to the laser lamp group. At the same time, it drives the annular rotating seat to rotate clockwise, so that the inner end of the buffer clamping assembly clamps on the bottom side of the weight assembly, realizing the fixation of the weight assembly;

[0012] When the sliding switch is pushed backward, the square conductive sheet on the conductive assembly contacts the corresponding circular conductive sheet, and the battery pack supplies power to the laser lamp group. At the same time, it drives the annular rotating seat to rotate counterclockwise, so that the inner end of the buffer clamping assembly no longer clamps the bottom side of the weight assembly, realizing the release of the weight assembly.

[0014] Preferably, a button groove is provided at the top of the installation groove, and buckle grooves are provided at the bottoms of both sides of the button groove;

[0015] The limit button assembly includes a limit button and a limit seat;

[0016] A button spring is fixed inside the limit button, and two groups of limit plates are symmetrically provided at the lower end of the limit button;

[0017] Side buckles that are inserted into the buckle grooves are symmetrically provided on both sides of the limit seat, and a U-shaped groove for clamping the limit plate is provided inside the side buckles.

[0018] Preferably, a positioning pin is provided at the upper part of the button groove, and the button spring is sleeved on the positioning pin.

[0019] Preferably, the bracket assembly includes a column fixed to the upper end of the annular end cover and a support fixed to the top of the column;

[0020] The cross-axis swing frame includes an annular connection seat and first connection pins fixed to the front and rear outer sides of the annular connection seat, and the first connection pins are inserted into the first pin holes on the support;

[0021] The weight assembly includes a top column and a bottom column fixed to the lower end of the top column through a connection platform. Second pin shafts are fixed to the left and right outer sides of the top column, and the second pin shafts are inserted into the second pin holes on the annular connection seat;

[0022] The laser lamp group includes a top laser lamp fixed to the upper end of the top column and side laser lamps fixed to the side of the connection platform, and a counterweight is also fixed to the side of the connection platform.

[0023] Preferably, the bottom column extends into the bottom cylinder, and magnet blocks are equidistantly distributed on the side of the bottom of the bottom cylinder.

[0024] Preferably, L-shaped grooves are provided on both sides of the top of the reserved groove. The buffer clamping assembly includes a moving plate slidably connected to two corresponding groups of L-shaped grooves, a sliding seat fixed to the bottom of the moving plate and slidably connected to the reserved groove, a abutting wheel movably connected to the middle of the outer side end of the sliding seat through a convex plate, a connecting cylinder fixed to the middle of the inner side end of the moving plate, a piston slidably connected inside the connecting cylinder, and an arc-shaped clamping seat connected to the middle of the inner side end of the piston through a support rod.

[0025] The abutting wheel abuts against the surface of the corresponding inclined plane.

[0026] Preferably, a cover is fixed to the outer side end of the connecting cylinder, the support rod passes through and extends out of the cover, and a first buffer spring is fixed to the middle of the inner side end of the piston.

[0027] Both outer side walls of the two ends of the moving plate are connected to the root of the inner side end of the L-shaped groove through second buffer springs.

[0028] Preferably, the U-shaped seat is fixed to the middle of the inner side of the sliding switch.

[0029] The conductive assembly includes a metal limiting rod fixed to the inner side end of the U-shaped seat, and both ends of the metal limiting rod penetrate and extend out through the inner side end of the vertical plate.

[0030] Preferably, the square conductive sheets are respectively located in front of the corresponding vertical plates, and the square conductive sheets are fixed to the metal limiting rods by metal connecting plates.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can realize the quick installation or disassembly of the battery pack through the limit button assembly. After the battery pack is installed, the limit button assembly limits the upper end face of the battery pack. At this time, whether holding the upper shell part or the battery pack part, the upper shell and the battery pack will not separate, making the installation of the battery pack and the upper shell more firm.

[0032] When closing, when the sliding switch is pushed forward, the square conductive sheet on the conductive assembly no longer contacts the corresponding circular conductive sheet, and the battery pack no longer supplies power to the laser lamp group, improving the service life of the battery pack. At the same time, it drives the annular rotating seat to rotate clockwise, so that the inner side end of the buffer clamping assembly clamps the side of the bottom of the weight hammer assembly, realizing the fixation of the weight hammer assembly, preventing the weight hammer assembly from shaking and hitting in the inner cavity of the upper shell when falling, and avoiding damage to the components in the inner cavity of the upper shell.

[0033] When turned on, when the sliding switch is pushed backward, the square conductive sheet on the conductive component contacts the corresponding circular conductive sheet, and the battery pack supplies power to the laser lamp group. At the same time, it drives the annular rotating seat to rotate counterclockwise, so that the inner end of the buffer clamping component no longer clamps the bottom side of the weight component, realizing the release of the weight component. This can improve the working efficiency of the laser line projector and facilitate the quick start-up of the laser line projector to the working state;

[0034] And after the weight component is released, the inner end of the arc-shaped clamp seat always extends into the inner side of the bottom cylinder, which prevents the laser line projector from accidentally falling during use and the weight component from shaking. The bottom column of the weight component first contacts the arc-shaped clamp seat, causing the arc-shaped clamp seat to drive the piston to further retract into the connecting cylinder through the support rod. At this time, since the first buffer spring is fixed to the inner end of the middle part of the piston, the first buffer spring plays a buffering role, thus further buffering the shaking of the bottom column and preventing the weight component from shaking and hitting in the inner cavity of the upper shell, avoiding damage to the components in the inner cavity of the upper shell.

Detailed implementation manners

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Embodiment:

[0058] Please refer to Figures 1 - 20 , the present invention provides a technical solution:

[0059] A laser line projector for surveying and mapping, including an upper housing 1 and a battery pack 5. A leg support 4 is provided at the bottom of the upper housing 1. Prism covers 2 are provided at the top and the side of the upper housing 1. The top laser lamp 1403 extends into the prism cover 2 at the top, and the side laser lamp 1402 extends into the corresponding prism cover 2 at the side;

[0060] After the battery pack 5 is snapped downward into the installation groove 103 at the rear of the upper housing 1, the output conductive sheet 502 at the inner bottom of the battery pack 5 is plugged and connected to the energized conductive sheet 101 at the bottom of the installation groove 103, and after the limit button assembly 6 at the top of the installation groove 103 pops out, it is stuck on the top of the battery pack 5;

[0061] The inner side of the battery pack 5 is provided with a snap block 501, and the two sides of the installation groove 103 are provided with raised blocks 102 for clamping on the side of the snap block 501. Such a setting enables the bottom of the battery pack 5 to be placed into the installation groove 103, and after pressing the battery pack 5 downward, the clamping connection between the battery pack 5 and the installation groove 103 at the rear of the upper housing 1 can be realized, achieving the rapid installation of the battery pack 5.

[0062] The top of the installation groove 103 is provided with a button groove 104, and the bottom of both sides of the button groove 104 is provided with a buckle groove 105;

[0063] The limit button assembly 6 includes a limit button 601 and a limit seat 602;

[0064] A button spring 6011 is fixed inside the limit button 601. Two groups of limit plates 6012 are symmetrically arranged at the lower end of the limit button 601. A positioning pin 106 is arranged at the upper part of the button groove 104, and the button spring 6011 is sleeved on the positioning pin 106;

[0065] As Figure 5 shown, the two sides of the limit seat 602 are symmetrically provided with side buckles 6022 that are snapped into the buckle grooves 105. Such a setting is conducive to realizing the rapid installation, disassembly and replacement of the limit seat 602;

[0066] A U-shaped groove 6021 for clamping the limit plate 6012 is arranged inside the side buckle 6022. In this way, after the button spring 6011 pops out the rear part of the limit button 601 from the button groove 104, the limit of the limit button 601 can be realized, preventing the limit button 601 from falling off after completely popping out of the button groove 104.

[0067] The upper housing 1 plays a guiding and supporting role during the forward and backward movement of the limit button 601, facilitating the positioning of the button spring 6011 and restricting the stroke range of the limit button 601.

[0068] The limit button 601 is also provided with a positioning pin 106 inside, so that the front and rear ends of the button spring 6011 are respectively sleeved on the corresponding positioning pins 106, facilitating the installation of the button spring 6011. The lower end surface of the limit button 601

[0069] Both ends of the limit seat 602 rely on elastic deformation to snap the side buckles 6022 at both ends into the buckle grooves 105, and rely on the U-shaped groove 6021 to limit the limit plate 6012 to realize the limit of the limit button 601 and prevent the limit button 601 from falling.

[0070] At the bottom of the inner cavity of the upper housing 1, a base 8 is fixed. At the upper end of the base 8, an annular end cover 7 is fixed. The support assembly at the upper end of the annular end cover 7 is provided with a weight assembly 14 through a cross-axis swing frame 11, and the cross-axis swing frame 11 enables the weight assembly 14 to swing back and forth, left and right;

[0071] The support assembly includes a column 9 fixed at the upper end of the annular end cover 7 and a support 10 fixed at the top of the column 9;

[0072] The cross-axis swing frame 11 includes an annular connection seat 1101 and first connection pins 1102 fixed on the front and rear outer sides of the annular connection seat 1101. The first connection pins 1102 are inserted into the first pin holes 1001 on the support 10;

[0073] The weight assembly 14 includes a top column 1406 and a bottom column 1407 fixed to the lower end of the top column 1406 through a connection platform 1405. Second pin shafts 1404 are fixed on the left and right outer sides of the top column 1406, and the second pin shafts 1404 are inserted into the second pin holes 1103 on the annular connection seat 1101;

[0074] The bottom column 1407 extends into the bottom cylinder 802, and magnet blocks 803 are equidistantly distributed on the bottom side of the bottom of the bottom cylinder 802. Under the suction force of the magnet blocks 803 on the bottom column 1407, the weight assembly 14 swings back and forth, left and right and then stops immediately, realizing the rapid stop of the weight assembly 14 so that the laser line level can quickly enter the working state;

[0075] The laser lamp group includes a top laser lamp 1403 fixed at the upper end of the top column 1406 and a side laser lamp 1402 fixed on the side of the connection platform 1405, and a counterweight 1401 is also fixed on the side of the connection platform 1405.

[0076] The base 8 includes a bottom cylinder 802 fixed at the bottom of the inner cavity of the upper housing 1 and an annular seat 801 connected to the outer side of the top of the bottom cylinder 802. An annular rotating seat 15 is provided in an annular groove 804 on the annular seat 801, and a buffer clamping assembly 12 is provided in reserved grooves 805 equidistantly arranged on the inner side of the annular groove 804;

[0077] L-shaped grooves 806 are provided on both sides at the top of the reserved grooves 805. The buffer clamping assembly 12 includes a moving plate 1201 slidably connected in corresponding two groups of L-shaped grooves 806, a sliding seat 1206 fixed at the bottom of the moving plate 1201 and slidably connected in the reserved groove 805, a abutting wheel 1208 movably connected to the middle of the outer end of the sliding seat 1206 through a convex plate 1207, a connecting cylinder 1202 fixed to the middle of the inner end of the moving plate 1201, a piston 1210 slidably connected inside the connecting cylinder 1202, and an arc-shaped clamping seat 1205 connected to the middle of the inner end of the piston 1210 through a support rod 1204;

[0078] A cover 1203 is fixed to the outer end of the connecting cylinder 1202. A support rod 1204 passes through and extends out of the cover 1203, and a first buffer spring 1209 is fixed to the inner end of the middle part of the piston 1210;

[0079] The outer side walls at both ends of the moving plate 1201 are connected to the inner end root of the L-shaped groove 806 through second buffer springs 807.

[0080] The inner end of the buffer clamping assembly 12 extends into the annular seat 801, and the outer end of the buffer clamping assembly 12 abuts against the corresponding inclined plane 1501 on the inner side of the annular rotating seat 15, that is, the abutting wheel 1208 abuts against the surface of the corresponding inclined plane 1501.

[0081] A sliding switch 3 is slidably connected to the side of the upper housing 1. A conductive assembly 13 extending into the inner cavity of the upper housing 1 is provided inside the sliding switch 3. The connecting column 1502 at the upper end of the annular rotating seat 15 extends out through the arc-shaped groove 701 on the annular end cover 7 and is inserted into the U-shaped seat 301 of the conductive assembly 13;

[0082] Vertical plates 702 are also provided on the annular end cover 7 on both sides of the arc-shaped groove 701, and a circular conductive sheet 704 is fixed in the inner groove 705 on the front surface of the vertical plate 702;

[0083] One circular conductive sheet 704 (i.e., the rear circular conductive sheet 704) is electrically connected to the corresponding energized conductive sheet 101 (the energized conductive sheet 101 of the negative electrode) through a wire, and the other circular conductive sheet 704 (i.e., the front circular conductive sheet 704) is electrically connected to the corresponding laser lamp group (i.e., the top laser lamp 1403 and the side laser lamp 1402) on the weight assembly 14 through a wire, and the laser lamp group is connected in series with the energized conductive sheet 101 of the positive electrode through a wire;

[0084] In this way, when the sliding switch 3 is pushed forward to the state as shown in Figure 10 and 18 , the square conductive sheet 1303 is separated from the front and rear groups of circular conductive sheets 704, so that the top laser lamp 1403 and the side laser lamp 1402 are no longer connected to the energized conductive sheet 101, and thus the battery pack 5 no longer supplies power to the laser lamp group;

[0085] When the sliding switch 3 is pushed backward to the state as shown in Figure 19 and 20 , the square conductive sheet 1303 is in contact with the front and rear groups of circular conductive sheets 704, so that the top laser lamp 1403 and the side laser lamp 1402 are connected to the energized conductive sheet 101, and the battery pack 5 supplies power to the laser lamp group.

[0086] As shown in Figure 10 , 16 and 19, the U-shaped seat 301 is fixed in the middle of the inner side of the sliding switch 3;

[0087] The conductive component 13 includes a metal limiting rod 1301 fixed to the inner side end of the U-shaped seat 301, and both ends of the metal limiting rod 1301 penetrate and extend out through the inner side end of the vertical plate 702.

[0088] The square conductive sheets 1303 are respectively located in front of the corresponding vertical plates 702, and the square conductive sheets 1303 are fixed to the metal limiting rod 1301 by metal connecting plates 1302.

[0089] When the sliding switch 3 moves back and forth along the side surface of the upper housing 1, the metal limiting rod 1301 also moves back and forth along the vertical plate 702. Such a setting can ensure the horizontal movement of the sliding switch 3 back and forth, making the movement of the sliding switch 3 smooth and stable;

[0090] Moreover, when the sliding switch 3 moves back and forth, the connecting column 1502 will move correspondingly along the U-shaped through groove inside the U-shaped seat 301, so that the U-shaped seat 301 drives the annular rotating seat 15 to rotate counterclockwise and clockwise through the connecting column 1502.

[0091] The penetrating connection between the metal limiting rod 1301 and the vertical plate 702 has a certain damping, and the connection between the sliding switch 3 and the side surface of the upper housing 1 also has a certain damping. After the sliding switch 3 moves back and forth, the sliding switch 3 will not move back to its original position, thereby avoiding unnecessary movement and reset of the conductive component 13 and the annular rotating seat 15.

[0092] When the sliding switch 3 is pushed forward, the conductive component 13 disconnects the connection between the laser lamp group and the energized conductive sheet 101, so that the battery pack 5 no longer supplies power to the laser lamp group. At the same time, the inner side end of the buffer clamping component 12 clamps the bottom side of the weight component 14. After the fixation of the weight component 14 is achieved, it prevents the weight component 14 from shaking and hitting inside the inner cavity of the upper housing 1 during a fall, avoiding damage to the components inside the inner cavity of the upper housing 1;

[0093] That is, when the sliding switch 3 is pushed forward, the square conductive sheet 1303 on the conductive component 13 no longer contacts the corresponding circular conductive sheet 704, the battery pack 5 no longer supplies power to the laser lamp group, and at the same time, it drives the annular rotating seat 15 to rotate clockwise, so that the inner side end of the buffer clamping component 12 clamps the bottom side of the weight component 14 to achieve the fixation of the weight component 14;

[0094] When the sliding switch 3 is pushed backward, the conductive component 13 connects the laser lamp group and the energized conductive sheet 101, so that the battery pack 5 supplies power to the laser lamp group. At the same time, the inner side end of the buffer clamping component 12 no longer clamps the bottom side of the weight component 14, realizing the release of the weight component 14. After the weight component 14 swings back and forth and then stops, the laser lamp group on the weight component 14 is leveled;

[0095] That is, when the sliding switch 3 is pushed backward, the square conductive sheet 1303 on the conductive component 13 contacts the corresponding circular conductive sheet 704. The battery pack 5 powers the laser lamp group. At the same time, it drives the annular rotating base 15 to rotate counterclockwise, so that the inner end of the buffer clamping component 12 no longer clamps the bottom side of the weight component 14, realizing the release of the weight component 14.

[0096] Specifically, during use, the battery pack 5 is fitted to the installation groove 103 at the rear of the upper housing 1. The bottom of the battery pack 5 is placed into the installation groove 103. After pressing the battery pack 5 downward, the buckle block 501 inside the battery pack 5 is clamped by the raised blocks 102 on both sides of the installation groove 103, thus realizing the quick installation of the battery pack 5.

[0097] And during the process of pressing the battery pack 5 downward, since the battery pack 5 has a forward pressure on the limit button 601, the limit button 601 overcomes the elastic force of the button spring 6011, so that the limit button 601 completely enters the button groove 104, and the button spring 6011 is in a compressed state.

[0098] When the battery pack 5 drops to the lowest position, the upper part of the battery pack 5 no longer abuts against the rear end of the limit button 601. At this time, under the elastic force of the button spring 6011, after the rear part of the limit button 601 pops out of the button groove 104, the limit button 601 is stuck on the top of the limit button 601 to limit the upper end face of the battery pack 5. At this time, whether holding the upper housing 1 part or the battery pack 5 part, the upper housing 1 and the battery pack 5 will not separate.

[0099] After the battery pack 5 is installed in place, the output conductive sheet 502 at the inner bottom of the battery pack 5 is inserted and connected to the energized conductive sheet 101 at the bottom of the installation groove 103, that is, the positive energized conductive sheet 101 is inserted into the positive output conductive sheet 502, and the negative energized conductive sheet 101 is inserted into the negative output conductive sheet 502.

[0100] When the battery pack 5 needs to be disassembled, first press the limit button 601 to completely press the limit button 601 into the button groove 104, and then gently push the battery pack 5 upward to remove the battery pack 5.

[0101] In the initial state, the sliding switch 3 is in the forward off (closed) position, as shown in Figure 10 and 18 the state shown, the square conductive sheet 1303 is separated from the front and rear groups of circular conductive sheets 704, so that the top laser lamp 1403 and the side laser lamp 1402 are no longer connected to the energized conductive sheet 101, so that the battery pack 5 no longer powers the laser lamp group.

[0102] Meanwhile, the U-shaped seat 301 drives the annular rotating seat 15 to rotate clockwise through the connecting column 1502. The abutting wheel 1208 gradually rolls towards the inner surface of the slope surface 1501. The slope surface 1501 pushes the abutting wheel 1208 inward, causing the moving plate 1201 to move along the L-shaped groove 806 towards the root of its inner end. The moving plate 1201 gradually compresses the second buffer spring 807. At this time, the arc-shaped clamping seat 1205 further extends inward until the arc-shaped clamping seat 1205 completely clamps and fixes the bottom column 1407.

[0103] When starting to use, the sliding switch 3 is in the rear on (on) position, as Figure 19 and 20 shown in the state. The square conductive sheet 1303 is in close contact with the front and rear groups of circular conductive sheets 704, enabling the top laser lamp 1403 and the side laser lamp 1402 to be connected to the energized conductive sheet 101, and the battery pack 5 supplies power to the laser lamp group.

[0104] Meanwhile, the U-shaped seat 301 drives the annular rotating seat 15 to rotate counterclockwise through the connecting column 1502. The abutting wheel 1208 rolls down along the inner surface of the slope surface 1501. At this time, under the elastic force of the second buffer spring 807 on the moving plate 1201, the moving plate 1201 moves along the L-shaped groove 806 towards its outer end to reset, and the arc-shaped clamping seat 1205 retracts outward until the arc-shaped clamping seat 1205 no longer contacts the side of the bottom column 1407.

[0105] At this time, with the release of the bottom column 1407, the entire weight hammer assembly 14 swings back and forth and left and right under the action of gravity until the entire weight hammer assembly 14 stops, so as to realize the horizontality of the laser lamp group on the weight hammer assembly 14.

[0106] The laser generated by the top laser lamp 1403 passes through the prism cover 2 at the top, and the laser generated by the side laser lamp 1402 passes through the corresponding prism cover 2 on the side.

[0107] And when the arc-shaped clamping seat 1205 does not contact the side of the bottom column 1407, the inner end of the arc-shaped clamping seat 1205 always extends into the inner side of the bottom cylinder 802. This prevents the laser line projector from accidentally falling during use, the weight hammer assembly 14 from shaking, and the bottom column 1407 of the weight hammer assembly 14 from contacting the arc-shaped clamping seat 1205 first, causing the arc-shaped clamping seat 1205 to drive the piston 1210 to further retract into the connecting cylinder 1202 through the support rod 1204. At this time, since the first buffer spring 1209 is fixed to the inner side end of the middle part of the piston 1210, the first buffer spring 1209 plays a buffering role, thereby further buffering the shaking of the bottom column 1407 and preventing the weight hammer assembly 14 from shaking and hitting in the inner cavity of the upper housing 1, avoiding damage to the components in the inner cavity of the upper housing 1.

[0108] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
