Description

[Technical Field]

[0001] The present invention relates to a cab-over vehicle. [Background technology]

[0002] BACKGROUND ART Light trucks are known that are equipped with connecting plates that connect rear pillars at both rear ends of the cabin to the front ends of the side panels of the cargo box, and a back panel of the cabin that also serves as a front panel of the cargo box.

[0003] The connecting plate is a single continuous plate with a front end fastened to the rear pillar and a rear end fastened to the front inner wall surface of the side panel via a cushioning material. The cushioning material prevents metal-to-metal contact between the rear pillar and the side panel. The cushioning material is made of rubber or a resin with rubber-like properties and is interposed between the front end of the side panel and the rear end of the rear pillar. The cushioning material adheres closely to both the side panel (the L-shaped cross-section bracket that is part of the side panel) and the rear pillar in the vehicle width direction, and adheres closely to the rear pillar in the vehicle front-to-rear direction, leaving a gap between it and the side panel.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 56-129370 Summary of the Invention [Problem to be solved by the invention]

[0005] Cab-over vehicles, such as light trucks, that have a cabin and a deck located behind the cabin may be equipped with a side gate that can be opened and closed and a locking device that holds the side gate closed. The side gate is also called a "gate gate." The locking device firmly holds the side gate closed to prevent cargo loaded on the deck from opening the side gate due to disturbances such as vehicle movement.

[0006] The stopper located between the side gate and the rear pillar may be subjected to a crushed state (environment) for a long period of time by the locking device that firmly holds the side gate in place. A stopper exposed to such an environment may not be able to return to its original shape and may become permanently deformed, leaving residual distortion in the stopper. This residual distortion in the stopper is called compression set.

[0007] If compression set remains in the stopper, there is a high possibility that a gap will form between the side gate and the stopper, or between the rear pillar and the stopper. These gaps will cause the locking device to insufficiently hold the side gate, causing it to rattle and make noise.

[0008] Therefore, an object of the present invention is to provide a cab-over vehicle that can suppress the compression set of the stopper sandwiched between the side gate and the rear pillar, thereby enabling the locking device to maintain good retention of the side gate. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the cab-over vehicle of the present invention comprises a cabin having a rear pillar located at the rear side, a deck located behind the cabin and having an openable and closable side gate located at the side edge in the vehicle width direction, a locking device that holds the side gate in a closed position, and a stopper provided on at least one of the rear pillar and the side gate and sandwiched between the rear pillar and the side gate when the side gate is closed, the stopper having a first portion that contacts the side gate when the side gate is closed and a second portion that has a lower density than the first portion. [Effects of the Invention]

[0010] According to the present invention, a cab-over vehicle can be provided that can suppress compression set of the stopper sandwiched between the side gate and the rear pillar, thereby enabling the side gate to be held in good condition by the locking device. [Brief explanation of the drawings]

[Figure 2] 1 is a perspective view showing a boundary portion between a rear pillar and a left side gate of a cab-over vehicle according to the present invention, viewed from diagonally rear left. [Figure 3] 2 is a plan view of a boundary area between a rear pillar and a left side gate of a cab-over vehicle according to the present invention. FIG. [Figure 4] FIG. 10 is a plan view of another example of the boundary portion between the rear pillar and the left side gate of the cab-over vehicle according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] A cab-over vehicle according to the present invention will be described below with reference to Figures 1 to 4. Note that the same or corresponding components are denoted by the same reference numerals throughout the drawings.

[0013] FIG. 1 is a perspective view showing a cab-over vehicle according to the present invention, viewed from the left rear.

[0014] In Figure 1, the solid arrow Fr indicates the fore-and-aft direction of the cab-over vehicle 1. For ease of explanation, hereinafter the cab-over vehicle 1 will be simply referred to as "vehicle 1." The direction in which the tip of the solid arrow Fr points is the front of the vehicle 1, and the opposite direction is the rear of the vehicle 1. In the following explanation, the right side as viewed from the front of the vehicle 1 will be referred to as the right, and the left side will be referred to as the left.

[0015] As shown in Fig. 1, the vehicle 1 according to this embodiment is a flatbed truck. The vehicle 1 includes a cabin 5 having a driver's seat and a deck 6 disposed behind the cabin 5. The cabin 5 is also called a cab. The deck 6 is capable of carrying cargo and is a so-called loading platform.

[0016] The cabin 5 defines a vehicle interior space in which a driver's seat is located. The cabin 5 includes a pair of openable and closable side doors 7 provided on each of the left and right sides in the vehicle width direction of the vehicle 1, a back panel 11 provided on the back of the cabin 5, and a pair of rear panels 12 provided on each of the left and right sides in the vehicle width direction of the vehicle 1 and disposed between the pair of side doors 7 and the back panel 11.

[0017] The back panel 11 covers the back portion 5 a of the cabin 5 .

[0018] The rear panel 12 covers the rear side 5 b of the cabin 5 .

[0019] The rear side portion 5b of the cabin 5 includes a rear panel 12 corresponding to the exterior, a first inner panel covered by the rear panel 12, and a second inner panel covered by the rear panel 12. The rear panel 12 is disposed outward in the vehicle width direction relative to the first inner panel and the second inner panel. The first inner panel is disposed below the second inner panel.

[0020] The rear side surface 5b of the cabin 5 is provided with a rear pillar reinforcement member extending in the vehicle vertical direction along the rear edge of the opening leading to the interior space through which the side door 7 opens and closes, and a rear pillar inner lower panel disposed closer to the center in the vehicle width direction than the lower region of the rear pillar reinforcement member. The rear pillar inner lower panel is disposed further forward of the first inner panel and lower than the second inner panel.

[0021] In a plan view of the vehicle 1, the rear panel 12, the first inner panel, and the rear pillar inner lower panel define a closed cross section in a lower region of the rear side surface 5b of the cabin 5. The rear side surface 5b of the cabin 5 includes a side brace disposed inside the closed cross section.

[0022] In the lower region of the rear side 5b of the cabin 5, the rear end of the brace is sandwiched between the rear end of the rear panel 12 and the rear end of the first inner panel, and the rear end of the brace, the rear end of the rear panel 12, and the first inner panel are joined together.

[0023] In the upper region of the rear side 5b of the cabin 5, the rear end of the brace is sandwiched between the rear end of the rear panel 12 and the side edge of the back panel 11, and the rear end of the brace, the rear end of the rear panel 12, and the side edge of the back panel 11 are joined together by, for example, spot welding.

[0024] The front end of the brace is joined to the rear end of the rear pillar reinforcement. The front end of the brace may be joined to another vehicle body member disposed on the rear side 5b of the cabin 5 instead of the rear pillar reinforcement.

[0025] The structure of the rear side 5b of the cabin 5 is called the rear pillar 15. In other words, the cabin 5 has the rear pillar 15 disposed at the rear side. Note that, except for the rear panel 12 that contributes to the design of the vehicle 1, the specific configuration of the rear pillar 15 is not limited to the above description.

[0026] The deck 6 includes a flat floor surface portion 21 on which luggage is loaded, and a plurality of movable gates 22a, 22b, 22c that can be opened and closed and that surround the left and right sides and rear of the floor surface portion 21.

[0027] The floor surface portion 21 is a metal sheet metal product. The floor surface portion 21 extends rearward from the back portion 5a of the cabin 5. In a plan view of the vehicle 1, the floor surface portion 21 has a rectangular shape that is long in the front-to-rear direction of the vehicle 1. The floor surface portion 21 is surrounded on all four sides, front, rear, left, and right, by the back panel 11 of the cabin 5 and three movable gates 22a, 22b, and 22c. The left and right side edges of the floor surface portion 21 in the vehicle width direction are supported from below by side members of the chassis that extend in the front-to-rear direction of the vehicle 1.

[0028] The movable gates 22a, 22b, and 22c are also called "gates." The left movable gate 22a is called the left gate or left side gate 22a, the right movable gate 22b is called the right gate or right side gate 22b, and the rear movable gate 22c is called the rear gate or rear gate 22c. The left side gate 22a and the right side gate 22b may be collectively or simply referred to as side gates 22a and 22b. The side gates 22a and 22b are located on the side edge 21a of the deck 6 in the vehicle width direction.

[0029] The side gates 22a, 22b are formed by processing metal sheets. In a side view of the vehicle 1, the side gates 22a, 22b have a rectangular shape that is long in the front-rear direction of the vehicle 1. The side gates 22a, 22b extend in the front-rear direction over the entire length of the floor portion 21.

[0030] The deck 6 is provided with hinge mechanisms provided on the left and right side edges 21a of the floor 21 that support the side gates 22a, 22b rotatably relative to the floor 21. In other words, the side gates 22a, 22b are rotatable about the hinge mechanisms between a closed position and an open position. The left side gate 22a stands perpendicular to the floor 21 in the closed position and defines the left edge of the loading space above the floor 21. The right side gate 22b stands perpendicular to the floor 21 in the closed position and defines the right edge of the loading space above the floor 21.

[0031] The side gates 22a, 22b move to the open position by rotating from the closed position around the hinge mechanism so as to tilt outward or to the side of the vehicle 1. In the open position, the left side gate 22a tilts parallel to the floor surface 21, i.e., horizontally, opening the floor surface 21 to the left. In the open position, the right side gate 22b tilts parallel to the floor surface 21, i.e., horizontally, opening the floor surface 21 to the right. The side gates 22a, 22b may open so as to hang downward from the side edges of the floor surface 21.

[0032] The rear gate 22c is a metal sheet metal product. The rear gate 22c has a rectangular shape that is long in the vehicle width direction when viewed from the rear of the vehicle 1. The rear gate 22c extends in the vehicle width direction across the entire width of the floor portion 21.

[0033] The deck 6 is provided with a hinge mechanism that is provided at the rear edge of the floor 21 and supports the rear gate 22c rotatably relative to the floor 21. In other words, the rear gate 22c is rotatable around the hinge mechanism between a closed position and an open position. In the closed position, the rear gate 22c stands perpendicular to the floor 21 and contacts the rear ends of the left and right side gates 22a and 22b, thereby defining the rear edge of the loading space above the floor 21.

[0034] The rear gate 22c moves to the open position by rotating from the closed position to the outward or rearward position using the hinge mechanism as a base point. In the open position, the rear gate 22c lies parallel to the floor 21, i.e., lies horizontally like the side gates 22a and 22b, opening the floor 21 to the rear. The rear gate 22c may also open by hanging downward from the rear edge of the floor 21.

[0035] The vehicle 1 also includes side lock devices 25a, 25b capable of holding the side gates 22a, 22b in a closed position, rear lock devices 25c1, 25c2 capable of holding the rear gate 22c in a closed position, and a load rest 27 provided on the rear portion 5a of the cabin 5.

[0036] The side lock devices 25a, 25b include a movable handle 31, a latch 32 attached to the handle 31, and a hook 33 provided on the rear pillar 15. The side lock devices 25a, 25b hold the side gates 22a, 22b in the closed position by hooking the latch 32 onto the hook 33.

[0037] The rear locking devices 25c1 and 25c2 include a movable handle 35, a latch 36 attached to the handle 35, and a hook 37 provided on the side gates 22a and 22b. The rear locking devices 25c1 and 25c2 hold the rear gate 22c in the closed position by hooking the latch 36 onto the hook 37.

[0038] The rear gate 22c can be opened by unlocking a pair of left and right rear locking devices 25c1 and 25c2. The left side gate 22a can be opened by unlocking the side locking device 25a and the left rear locking device 25c1. The right side gate 22b can be opened by unlocking the side locking device 25b and the right rear locking device 25c2.

[0039] The load rest 27 can be used as a support against which long cargo such as planks can lean when loading them onto the deck 2.

[0040] FIG. 2 is a perspective view showing the boundary between the rear pillar and the left side gate of the cab-over vehicle according to the present invention, viewed obliquely from the rear left.

[0041] FIG. 3 is a plan view of a boundary area between a rear pillar and a left side gate of a cab-over vehicle according to the present invention.

[0042] The boundary between the rear pillar 15 and the right side gate 22b has the same configuration as that shown in FIG. 2, and therefore a description thereof will be omitted to avoid repetition.

[0043] As shown in Figures 2 and 3, the vehicle 1 according to this embodiment is provided with a stopper 41 that is provided on the rear pillar 15 and is sandwiched between the rear pillar 15 and the left side gate 22a when the left side gate 22a is closed.

[0044] The stopper 41 has a first buffer portion 42 that is sandwiched between the rear pillar 15 and the left side gate 22a when the left side gate 22a is closed, and a second buffer portion 43 that is fixed to the rear pillar 15. The two buffer portions 42, 43 are arranged to form an L shape.

[0045] When the left side gate 22a is closed, the first buffer portion 42 contacts and is sandwiched between both the rear pillar 15 and the left side gate 22a, and is compressed in the vehicle width direction by the side lock devices 25a, 25b, being crushed and distorted.

[0046] Whether the left side gate 22a is closed or open, the second buffer portion 43 does not come into contact with the left side gate 22a and is separated from it, so it is not crushed or distorted unless a large load acts on the left side gate 22a in the forward direction of the vehicle. The second buffer portion 43 is provided with a support protrusion 45 that supports the stopper 41 on the rear pillar 15. The support protrusion 45 is elastically deformable to pass through a stopper mounting opening 46 provided in the rear pillar 15, and when the elastic deformation is restored, it becomes unable to come out of the stopper mounting opening 46, thereby supporting the stopper 41 on the rear pillar 15.

[0047] Therefore, the L-shaped stopper 41 has the function of preventing direct contact between the left side gate 22a and the rear pillar 15 in both the vehicle width direction and the fore-and-aft direction of the vehicle 1, thereby protecting them from damage.

[0048] The stopper 41 also has a high-density portion 51 (first portion) that contacts the left side gate 22a when the left side gate 22a is closed, and a low-density portion 52 (second portion) that has a lower density than the high-density portion 51.

[0049] The material of the high density portion 51 is, for example, a rubber material, and its density is, for example, 0.8 grams per cubic centimeter (g / cm 3 The material of the low density portion 52 is, for example, a foaming agent, and its density is, for example, 0.3 grams per cubic centimeter to 0.7 grams per cubic centimeter.

[0050] The high-density portion 51 has a contact surface 51a for the left side gate 22a. This contact surface 51a is part of the surface of the stopper 41 and is also the contact surface of the stopper 41 that comes into contact with the left side gate 22a.

[0051] In the vehicle width direction, the low-density region 52 is sandwiched between the high-density regions 51. The high-density region 51 contacts the left side gate 22a when the left side gate 22a is closed, and also contacts the rear pillar 15. In other words, it is preferable that the low-density region 52 does not contact the left side gate 22a when the left side gate 22a is closed, and it is also preferable that the low-density region 52 does not contact the rear pillar 15. Therefore, the stopper 41 can have both softness to prevent direct contact between the left side gate 22a and the rear pillar 15 to protect them from damage, and hardness to generate a required reaction force against the force acting from the side lock devices 25a, 25b so that the left side gate 22a fixed by the side lock devices 25a, 25b does not move.

[0052] For ease of explanation, the region in the vehicle width direction where the low-density regions 52 are arranged and sandwiched between the high-density regions 51 will be referred to as the low-resilience region LRA, and the region where the high-density regions 51 are arranged and sandwiching the low-density regions 52 will be referred to as the high-resilience region HRA. The low-resilience region LRA may contain a mixture of high-density regions 51 and low-density regions 52, as long as the low-density regions 52 dominate in repulsion force. Also, the high-resilience region HRA may contain a mixture of high-density regions 51 and low-density regions 52, as long as the high-density regions 51 dominate in repulsion force. In other words, it is sufficient that the average density of the low-resilience region LRA is lower than the average density of the high-resilience region HRA.

[0053] For example, the low-density portion 52 may be located in a position that contacts the left side gate 22a when the left side gate 22a is closed. In such a case, it is preferable that the high-density portion 51 and the low-density portion 52 are exposed together on the contact surface of the stopper 41 so that the high-density portion 51 and the low-density portion 52 contact the left side gate 22a together. The same applies when the low-density portion 52 contacts the rear pillar 15 when the left side gate 22a is closed. Specifically, the high-density portion 51 and the low-density portion 52 may appear in a houndstooth pattern or a striped pattern on the contact surface of the stopper 41.

[0054] The high density portion 51 and the low density portion 52 may be an integrally molded product, or may be formed by joining together separate members. The high density portion 51 and the low density portion 52 may be molded from the same material, or may be molded from different materials.

[0055] For example, Japanese Patent Application Laid-Open No. 2009-248400 discloses a foam-molded product (stopper 41) having a mixture of a skin layer (corresponding to high-density region 51) and a foam layer (corresponding to low-density region 52). With the fixed mold and the movable mold mated, the cavity formed by the fixed mold and the movable mold is filled with molten resin. Then, the movable mold alone is retracted a predetermined distance in the mold opening direction, releasing the pressure in the cavity and foaming the molten resin. This produces a foam-molded product having a mixture of a skin layer and a foam layer.

[0056] The low-density region 52 may be foamed sponge rubber using microcapsules as a foaming agent. Sponge rubber has many air bubbles formed by the expansion of the microcapsules. In each air bubble, the shell of the microcapsule used as the foaming agent does not maintain its spherical shape and remains. The shell does not completely adhere to the inner surface of the air bubble, reducing the rigidity of the air bubble.

[0057] For example, a cushion made of a single material such as rubber may be placed in a crushed state (environment) for a long period of time by the side lock devices 25a, 25b that hold the left side gate 22a. Cushion materials exposed to such an environment may not be able to return to their original shape and may be permanently deformed, resulting in residual distortion.

[0058] Therefore, the stopper 41 according to this embodiment ensures elasticity in the high-density portion 51 sufficient to cushion contact between the left side gate 22a and the rear pillar 15, while suppressing permanent deformation (permanent strain) due to compressive forces acting from the side lock devices 25a, 25b in the low-density portion 52. The low-density portion 52 has lower resilience than the high-density portion 51, and even if crushed by the side lock devices 25a, 25b, it is more likely to return to its original shape than the high-density portion 51 when the side lock devices 25a, 25b are unlocked. Therefore, when the left side gate 22a is secured by the side lock devices 25a, 25b, the stopper 41 absorbs deformation in the low-density portion 52 and reduces permanent deformation in the high-density portion 51. In other words, the stopper 41 can suppress flapping of the left side gate 22a for a long period of time.

[0059] In the vehicle longitudinal direction, the stopper 41 is sandwiched between the left side gate 22a and the rear pillar 15 in a compression range CR that extends from the front end 22f of the left side gate 22a to the rear end 41b of the stopper 41. In other words, the stopper 41 is likely to be permanently deformed by the compressive force acting from the side lock devices 25a, 25b in the compression range CR. Therefore, in the vehicle longitudinal direction, the low-density region 52 is provided over a range from the rear end 41b of the stopper 41 forward of the front end 22f of the left side gate 22a. In other words, the low-density region 52 is efficiently disposed in the compression range CR, which is likely to be compressed by the left side gate 22a and the rear pillar 15.

[0060] As explained above, it is sufficient that the low-density portion 52 is provided in the first buffer portion 42 of the stopper 41. The second buffer portion 43 may be formed only with the high-density portion 51, or may be formed by mixing the high-density portion 51 and the low-density portion 52. It is preferable that the support protrusion 45 of the second buffer portion 43 does not easily come out of the stopper mounting opening 46. Therefore, it is preferable that the support protrusion 45 of the second buffer portion 43 is formed only with the high-density portion 51. The support protrusion 45 formed only with the high-density portion 51 can firmly hold the stopper 41 to the rear pillar 15 so that the stopper 41 does not fall off from the rear pillar 15.

[0061] FIG. 4 is a plan view of another example of the boundary portion between the rear pillar and the left side gate of the cab-over vehicle according to the present invention.

[0062] 4, the second example stopper 41A of the vehicle 1 according to this embodiment includes, in the vehicle width direction, a high-density region 51 that contacts the left side gate 22a when the left side gate 22a is closed, and a low-density region 52 that contacts the rear pillar 15 when the left side gate 22a is closed. In other words, the high-density region 51 and the low-density region 52 are arranged in layers and adjacent to each other in the vehicle width direction. Therefore, when the left side gate 22a is closed, the high-density region 51 contacts the left side gate 22a, and the low-density region 52 contacts the rear pillar 15.

[0063] In addition, the stopper 41A of the second example only needs to have, in the vehicle width direction, a high-rebound area HRA (an area where the high-density portion 51 is dominant in terms of repulsive force) located on the left side gate 22a side, and a low-rebound area LRA (an area where the low-density portion 52 is dominant in terms of repulsive force) located on the rear pillar 15 side.

[0064] The low-density region 52 (low-resilience region LRA) disposed on the rear pillar 15 side is crushed when the left side gate 22a is secured by the side lock devices 25a, 25b. In other words, the stopper 41A of the second example increases the contact area between the low-density region 52 (low-resilience region LRA) and the rear pillar 15 when the left side gate 22a is secured by the side lock devices 25a, 25b, more than the stopper 41 of the first example. This increase in contact area keeps the left side gate 22a secured more firmly.

[0065] The stopper 41, 41A may be provided on the left side gate 22a. In other words, the stopper 41 may be provided on at least one of the rear pillar 15 and the left side gate 22a.

[0066] The vehicle 1 according to this embodiment, configured as described above, includes stoppers 41, 41A each having a high-density region 51 that contacts the side gates 22a, 22b when the side gates 22a, 22b are closed, and a low-density region 52 that is lower in density than the high-density region 51. In other words, the stoppers 41, 41A are both soft enough to prevent direct contact between the side gates 22a, 22b and the rear pillar 15 to protect them from scratches, and hard enough to generate a required reaction force against the force applied by the side lock devices 25a, 25b to prevent movement of the side gates 22a, 22b secured by the side lock devices 25a, 25b. Therefore, the vehicle 1 can suppress the flapping of the side gates 22a, 22b over a long period of time and can maintain good retention of the side gates 22a, 22b by the side lock devices 25a, 25b over a long period of time.

[0067] Furthermore, the vehicle 1 according to this embodiment is provided with stoppers 41, 41A having low-density regions 52 that are provided in the vehicle longitudinal direction from the rear ends 41b of the stoppers 41, 41A across a compression range CR that is forward of the front ends 22f of the side gates 22a, 22b. In other words, the vehicle 1 is provided with stoppers 41, 41A having low-density regions 52 that are efficiently arranged in the compression range CR. By limiting the application areas of the low-density regions 52, the structural complexity of the stoppers 41, 41A is reduced, and they are not inferior in terms of manufacturing efficiency and other factors compared to stoppers made of a single material.

[0068] However, if the entire stoppers 41, 41A were made of the same foaming agent as the low-density portion 52, it would be difficult to obtain the hardness required to generate a reaction force against the force applied by the side locking devices 25a, 25b so as to prevent the side gates 22a, 22b secured by the side locking devices 25a, 25b from moving. Therefore, the vehicle 1 according to this embodiment includes high-density portions 51 that sandwich the low-density portion 52 in the vehicle width direction and contact the rear pillar 15 when the side gates 22a, 22b are closed. Therefore, the stoppers 41, 41A of the vehicle 1 can have both the softness required to prevent direct contact between the side gates 22a, 22b and the rear pillar 15 to protect them from damage, and the hardness required to generate a reaction force against the force applied by the side locking devices 25a, 25b so as to prevent the side gates 22a, 22b secured by the side locking devices 25a, 25b from moving.

[0069] Furthermore, the vehicle 1 according to this embodiment is provided with stoppers 41, 41A that are arranged so that the second buffer portion 43 fixed to the rear pillar 15 and the first buffer portion 42 sandwiched between the rear pillar 15 and the side gates 22a, 22b when the side gates 22a, 22b are closed form an L-shape. Therefore, the vehicle 1 can protect the side gates 22a, 22b from direct contact with the rear pillar 15 in both the vehicle width direction and the front-to-rear direction of the vehicle 1 by using the stoppers 41, 41A, which are single components.

[0070] Furthermore, the vehicle 1 according to this embodiment includes stoppers 41, 41A having high-density portions 51 made of rubber and low-density portions 52 made of a foaming agent. Therefore, the vehicle 1 can employ stoppers 41, 41A that can be easily manufactured by various known methods.

[0071] Therefore, according to the vehicle 1 of the present invention, the compression set of the stoppers 41, 41A sandwiched between the side gates 22a, 22b and the rear pillar 15 can be suppressed, thereby maintaining good retention of the side gates 22a, 22b by the side lock devices 25a, 25b.

[0072] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
