Description

Technical Field

[0001] The present invention relates to a flush door for a vehicle, and more particularly to a method of assembling a flush door for a vehicle, wherein the flush door is assembled by inserting from an outside to an inside while a sliding member is fixed by a separate rail. Background Art

[0002] Typically, a flush door for a vehicle is implemented in a structure without a step or offset between the glass (eg, window or door glass) and the trim by attaching a glass slide to the door glass or window included in the door of the vehicle.

[0003] In particular, the flush door can be realized as a modular flush door by modular tracks, glass run channels (e.g., glass slides), and trims (which are components of a glass slide assembly for the door glass). For example, the modular flush door can include modular tracks, modular glass run channels, and modular trims.

[0004] Thus, the modular flush door offers the advantage that the track, glass run and trim that constrain the glass slide assembly can be inserted in series into a modular state during the assembly process.

[0005] However, modular flush doors have a number of structural deficiencies that need to be addressed.

[0006] For example, as a first structural defect, it is difficult to assemble a glass sliding member assembly for door glass due to the integrated structure of the glass run and the track. As a second structural defect, production / management and assemblability are required to assemble the modular structure of the glass channel and decorative parts, thereby excessively increasing the cost compared to a general door structure. As a third structural defect, the glass sliding member is restricted by the glass run, resulting in excessive movement or distribution of the door glass. As a fourth structural defect, the glass sliding member cannot be assembled in series. As a fifth structural defect, since the glass sliding member is a moving trajectory toward the glass run, it is difficult to ensure the fixability of the door glass. Summary of the Invention

[0007] Therefore, in view of the problems in the background technology section, the present invention aims to provide a flush door for a vehicle and a method for assembling a flush door, wherein the flush door has a detachable sliding member fixing track. The flush door includes a sliding member for guiding the glass to move up and down. The sliding member is surrounded by a track arranged at an internal position of the door frame and a decorative member arranged at an external position to form a U-shaped cross-section. Specifically, the track and the decorative member overlap with each other, thereby achieving in-line assembly through the separation structure of the track and the decorative member (forming a "U"-shaped cross-section). In particular, the separation (e.g., spaced apart) structure of the track and the decorative member enables the assembly of components from the outdoor side (of the door) to the indoor side in the order of the track, glass and sliding member, decorative panel and decorative member. Thereby, the assemblability can be improved without the need for component modular equipment and module installation labor-saving equipment, thereby reducing the cost of the flush door and the vehicle including the flush door.

[0008] To achieve at least the aforementioned objectives, a flush door with a removable slider fixing track according to the present invention is provided. The flush door comprises: a body-in-white (BIW) door having a door frame; a door module mounted on the door frame; a glass pane configured to move up and down via the door module; and a slider. The slider includes a movement guide comprising a connection portion connected to the glass pane and a main portion positioned within a U-shaped cross-section formed by the track and the decorative panel. The track and the decorative panel are configured separately, with the decorative panel covering the open cross-section of the track and guiding the movement of the slider.

[0009] The track may be located inside the door frame, and the decorative panel may cover the open section of the track outside the door frame.

[0010] Tracks, glides and trim panels are made of hard material.

[0011] When the track and the decorative plate are spaced apart, the track and the decorative plate can form a U-shaped section in the overlapping section where the opening section of the track is covered by the decorative plate. The U-shaped section supports the reaction force of the BIW door generated by the up and down movement of the glass.

[0012] A micro gap structure may be included in the U-shaped cross section, and the micro gap structure may restrict the glass at a position corresponding to the up and down movement of the glass.

[0013] A glass run inner lip may be assembled to the track, and the glass run inner lip may form an airtight seal on the inside of the glass.

[0014] The glass and the connection part are bonded by a sealant.

[0015] The main body of the slider can absorb the distribution of the U-shaped cross section, that is, the movement of the U-shaped cross section. The main body can absorb the distribution of the U-shaped cross section by utilizing the elasticity of the tension portion. The main body can have an inlet portion provided on its upper and lower portions, the inlet portion having a rounded structure and suppressing the occurrence (e.g., generation) of noise during the upward and downward movement of the slider.

[0016] Grease may be applied between the open cross section of the rail and the main body of the slider, and the grease may compensate for friction generated by the up-and-down movement of the slider.

[0017] The glass and the sliding member may be connected by bonding a sealant to the connecting portion.

[0018] The trim of the BIW door is constructed by bonding the trim panel to the trim cover. The outer lip of the glass run assembled to the trim cover forms an airtight seal on the outside of the glass.

[0019] The door frame is provided with a positioning hole and a bolt hole; the rail is restrained by combining the guide pin with the positioning hole; and the decorative panel is restrained by combining the insert bolt with the bolt hole.

[0020] A nut may be applied to a fixing portion of the trim panel; a screw may be applied to a fixing portion of the rail; and a gasket may be applied to a contact portion of the rail.

[0021] A BIW door may be constructed by combining a door frame and a door inner panel over an inner panel cover, and an inner panel cover lip assembled to the inner panel cover forms an airtight seal on the inner side of the glass.

[0022] In addition, in order to achieve at least the above-mentioned purposes, a method for assembling a flush door with a removable slider fixing track is provided. The method includes the following steps: on the outside of the body-in-white (BIW) door, inserting the track into the door frame and coupling the glass run to the track; on the inside of the BIW door, installing the door module on the door frame; on the outside of the BIW door, installing the slider and the integrated glass on the door module; and coupling the slider to the track. The method also includes: forming a U-shaped cross-section by covering the open cross-section of the track on the outside of the BIW door with a decorative cover and a decorative panel in the decorative member and an inner lip of the glass run. The method also includes: forming an airtight seal on the inside of the glass by the inner lip of the glass run; coupling the decorative cover to the decorative panel; coupling the door inner panel to the door frame; and on the inside of the BIW door, covering the door inner panel with an inner panel cover.

[0023] The method further includes the steps of restraining the rail and the door frame by means of guide pins of the rail and positioning holes of the door frame, and restraining the decorative panel and the door frame by means of inserting bolts of the decorative panel and bolt holes of the door frame.

[0024] On the inside of the glass, assemble the glass run inner lip to the track. On the inside of the glass, apply the inner panel cover lip to the inner panel cover to create an airtight seal. Use double-sided tape to bond the trim cover to the trim panel; apply a gasket to the door frame to prevent noise from the track; secure the nut to the trim panel; and secure the screw to the track.

[0025] The flush vehicle door with a detachable sliding member fixing track of the present invention achieves the following operations and effects.

[0026] First, by inserting and assembling the tracks, glass slides, and decorative panels and covers sequentially from the exterior side to the interior side, assemblability can be improved compared to a conventional modular production process.

[0027] Second, the cost of modular components and investment in production facilities for module assembly can be reduced, thereby minimizing cost increases and ensuring competitiveness in terms of product cost.

[0028] Third, since the rails and decorative panels, which are components that the slide moves up and down, are made of aluminum rigid bodies, it is easy to ensure up and down movement performance compared to conventional hard materials and has excellent wear resistance.

[0029] Fourth, by realizing a structure that minimizes the position and assembly position distribution of the glass and decorative panels, the tilting problem that occurs when the glass moves up and down can be solved.

[0030] Fifth, since only minimal changes are required in conventional production processes, the present invention can be applied without modifying conventional production lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following describes embodiments of the present invention in detail with reference to the accompanying drawings. The embodiments described herein are merely exemplary embodiments, and the present invention can be implemented in various forms by a person skilled in the art. Therefore, the present invention is not limited to the disclosed embodiments.

[0039] When a component, device, element, etc. of the present invention is described as having a purpose or performing an operation, function, etc., the component, device or element should be considered herein as "configured to" satisfy the purpose or perform the operation or function.

[0040] refer to Figures 1 to 4 The flush door 100 includes, as components, a BIW door (body in white) 1, a track 2, a glass run 3, a door module 4, door glass or window (i.e., glass 5), a slider 6, a decorative strip (i.e., decorative member 7), an outer band 8a, an inner band 8b, and an inner panel cover 9. The flush door 100 also includes, as airtight members or components, a sealant 10, a glass run outer lip 11, a glass run inner lip 14, a gasket 17, and an inner panel cover lip 18. The flush door 100 also includes, as fastening components, nuts 19 and screws 20.

[0041] Specifically, the flush door 100 achieves a flush structure without steps or offsets between the glass 5 and the decorative member 7. The flush door 100 defines the upward / downward or vertical movement guide of the slider 6 by separating the track 2 located on the inside of the door and the decorative panel 13 located on the outside of the door based on the position of the slider 6 on which the glass 5 operates. Therefore, compared to conventional structures in which a glass module integrating the glass, track, decorative cover, decorative panel, glass run inner lip, and glass run outer lip is installed on the door frame 15, no separate module and equipment are required. Specifically, separate labor-saving equipment for installing the glass module is also not required in the production line. Therefore, costs can be saved when manufacturing flush doors and vehicles incorporating flush doors with removable slider fixing tracks.

[0042] refer to Figure 2 as well as Figure 1 , showing the detailed structure of the components and assembly parts of the flush door 100.

[0043] For example, the BIW door 1 is a door structure having an inner space for door components and a top frame structure. The BIW door 1 includes a door frame 15 and a door inner panel 16. One side of the door frame 15 is located on the track 2, and the other side is located on the decorative cover 12. The door inner panel 16 is attached to the door frame 15. Both sides of the door inner panel 16 can be fixed to the door frame 15 by welding.

[0044] In particular, the BIW door 1 blocks external exposure by using a built-in door component space to embed the door module 4. The BIW door 1 is combined with a top frame structure to expose the glass run 3 and the decorative member 7 (ie, the decorative cover 12) to the outside.

[0045] For example, the track 2 is made of a hard material (e.g., a rigid body). The airtight portion extends to one side of the quadrilateral body, allowing the glass run inner lip 14 to fit or be bonded to the track 2. The end or exposed edge of the slider 6 can be installed by inserting it into the open cross-sectional structure of the track 2. The end of the slider can be installed through an insert portion that extends into the open cross-sectional structure of the track 2 provided on the other side of the quadrilateral body.

[0046] Therefore, the track 2 has an open cross-section structure and is supported by being fastened to the top frame structure of the BIW door 1 using hardware.

[0047] For example, the glass run 3 is integrally constructed with a frame molding and a fixed glass 3a, and is assembled to the top frame structure of the door frame 15, so that the glass 5 is installed, specifically fitted into the door frame 15, to fix the glass run 3 and the door frame 15 with a fastening portion holding one side. In this case, the glass run 3 can be assembled while being supported by the door frame 15 and the door trim at some points on the outer surface.

[0048] Therefore, the glass run channel 3 is installed on the BIW door 1 assembled with the integrated structural track 2 .

[0049] For example, the door module 4 includes a motor for generating an operating force to move the glass 5 up and down. The operating force of the motor is transmitted to the slider 6 bonded to the glass 5 and the sealant 10, so that the glass 5 moves up and down relative to the U-shaped section formed by the track 2 and the decorative panel 13.

[0050] For example, the glass 5 is formed as a combined body with a slider 6 to move up and down, and is mounted on the door module 4 .

[0051] Specifically, the sliding members 6 are located on the left and right sides of the glass 5 .

[0052] For example, the sliding member 6 is made of a hard (e.g., rigid) material, a portion of which is formed by an adhesive portion that is bonded to the glass 5 and the sealant 10, and another portion of which is formed by a fitting portion that is inserted into the open cross-sectional structure of the rail 2. In one example, the sliding member 6 is configured as two sliding members 6 provided on the left and right sides of the glass 5. In this case, a portion is a connecting portion 6b (see Figure 3 ), the other part is the main body 6a (see Figure 3 ).

[0053] In particular, the slide 6 comprises a spring structure (ie, Figure 3 The spring structure absorbs the distribution of the U-shaped cross section formed by the track 2 and the decorative plate 13. In this case, the distribution of absorption is in the L direction and T direction positions where the glass moves up and down.

[0054] Therefore, the slider 6 is mounted on the open cross-section structure of the rail 2 , and grease is applied between the rail 2 and the slider 6 to compensate for the friction generated with the rail 2 when the slider 6 moves up and down together with the glass 5 .

[0055] For example, the decorative member 7 is fastened to the BIW door 1 using bolts. Specifically, the decorative member 7 is coupled to the B-pillar frame of the frame structure of the door frame 15 and is configured as a B-pillar of the vehicle 200 (see FIG. Figure 7 ).

[0056] To this end, the decorative member 7 includes a decorative cover 12, which is attached to the outside of the door frame 15 and forms the exposed portion of the vehicle's B-pillar. A decorative panel 13, made of a hard (e.g., a rigid body) material, is attached to the inside of the door frame 15 and covers the inside of the B-pillar. The decorative cover 12 and decorative panel 13 support the reaction force toward the outside of the BIW door 1 generated when the combination of the glass 5 and the slider 6 moves up and down, thereby preventing the glass 5 from changing position. In this case, the position change is prevented in the L direction.

[0057] In particular, the decorative plate 13 has a micro-gap structure (ie, Figure 4 The trim panel 13 and / or the micro-gap structure specifically restrict the vertical movement of the glass 5 to prevent shaking. In this case, the restrictions are on the vertical movement of the glass in the front-to-back, lengthwise, or L-direction, and side-to-side, widthwise, or T-direction (relative to the vehicle).

[0058] Therefore, by covering the open section of the rail 2 with the decorative plate 13 , the decorative member 7 is formed into a U-shaped section.

[0059] For example, the outer belt 8a is attached to the outer side of the BIW door 1 and the inner belt 8b is attached to the inner side of the BIW door 1 , and the outer belt 8a and the inner belt 8b are constructed as boundary areas of the top frame structure of the door frame 15 of the BIW door 1 .

[0060] For example, the inner panel cover 9 is added to the inner side of the BIW door 1 and covers the mounting holes or fastening hole portions (e.g., fastening portions of nuts / screws) of the door frame 15 and the door inner panel 16 to prevent them from being exposed. Therefore, the inner panel cover 9 is used to cover the hole portions to prevent them from being visible from the inside of the vehicle (i.e., the interior of the vehicle).

[0061] Specifically, the inner panel cover 9 is provided with a lip insertion portion at a predetermined area or position, and the inner panel cover lip 18 is assembled.

[0062] For example, the sealant 10 is applied to the adhesive portion of the sliding member 6 to fixedly adhere the sliding member 6 to the glass 5. In this case, the sealant 10 is applied to each of the two sliding members 6 provided on the left and right sides (i.e., the front and rear ends or edges) of the glass 5.

[0063] For example, the glass run outer lip 11, together with the trim cover 12 and the trim panel 13, forms an assembly of the trim member 7 and is assembled to the trim cover 12 to form an airtight seal between the trim cover 12 and the glass 5 at the outer side or edge of the glass 5. The glass run inner lip 14 is assembled to an airtight portion, which is an extension of the track 2, to form an airtight seal on the inner side of the glass 5. The inner panel cover lip 18 is assembled to a lip insert of the inner panel cover 9 to form an airtight seal on the inner side of the glass 5.

[0064] For example, a gasket 17 is added to a joining portion of the door frame 15 and the rail 2 between the rail 2 and the door frame 15 to prevent noise from being generated with the frame due to hardware fastening of the rail 2 and the door frame 15 .

[0065] For example, the nut 19 is fastened to the insert bolt 7a (see FIG. Figure 3 ), to couple the decorative panel 13 to the door frame 15. The screws 20 are fastened to the overlapping portion of the door frame 15 and the door inner panel 16 and coupled to the quadrilateral body of the track 2 to fix the door frame 15 to the door inner panel 16.

[0066] In addition, reference Figure 3 and Figure 4 , showing the sliding member coupling structure between the glass 5 and the sliding member 6, the track coupling structure between the door frame 15 and the track 2, and the coupling structure between the door frame 15 and the decorative member 7 (ie, the decorative panel 13).

[0067] refer to Figure 3The slider coupling structure includes a slider mounting portion 5b provided on a glass frame 5a serving as an edge of the glass 5 and includes a connecting portion 6b (ie, an adhesive portion) provided on a main body portion 6a of the slider 6.

[0068] Therefore, when the glass 5 and the sliding member 6 are combined, the glass 5 and the sliding member 6 are combined and fixed by adhesion of the sealant 10 in a state in which the connecting portion 6 b is added to the sliding member mounting portion 5 b.

[0069] Specifically, the slider 6 includes an entry portion 6c and a tension portion 6d on the main body portion 6a. The tension portion 6d has a spring structure that overlaps when coupled to the rail 2 by being inserted into the insertion portion of the open cross-section structure of the rail 2. The entry portion 6c forms both rounded end portions (i.e., the upper and lower portions) of the main body portion 6a to prevent any noise from being generated when the slider 6 moves up and down in the rail 2.

[0070] Furthermore, the tensioning portion 6d has a plurality of upper protrusions, forming a nodular structure, protruding from the middle of the main body 6a toward the upper surface of the main body, as well as side protrusions protruding from the upper and lower portions of the main body 6a toward the side surfaces of the main body. This allows the tensioning portion 6d to utilize the body's elasticity to absorb any distribution or movement that may occur. In this case, the tensioning portion absorbs any distribution or movement of the glass in the L and T directions.

[0071] refer to Figure 4 The track coupling structure is composed of a guide pin 2a protruding from the track 2 and a positioning hole 15a bored in the door frame 15. The decoration member coupling structure is composed of an insertion bolt 7a protruding from the decoration plate 13 of the decoration member 7 and a bolt hole 15b bored in the door frame 15.

[0072] Therefore, when the rail 2 and the door frame 15 are combined, the guide pins 2 a are fitted into the positioning holes 15 a so that the rail 2 is restrained to the door frame 15 , and the rail 2 and the door frame 15 are fastened using the screws 20 .

[0073] In addition, when the trim panel 13 and the door frame 15 are combined, the bolt 7 a is inserted through the bolt hole 15 b and screwed to the nut 19 , so that the garnish 7 is restrained to the door frame 15 in a state where the trim panel 13 and the door frame 15 are screwed together.

[0074] As described above, the rail 2 and the decorative plate 13 that determine the upward / downward trajectory of the glass are both mounted on the door frame 15, and their positions are restricted to provide a structure that is advantageous for management of undesired movement or distribution.

[0075] at the same time, Figure 7 A vehicle 200 is shown in which the flush door 100 is applied.

[0076] As shown in the figure, the vehicle 200 includes a flush door 100. The flush door 100 realizes a flush structure without a step or offset between the glass 5 and the trim 7.

[0077] Therefore, the flush door 100 is the reference Figures 1 to 4 The flush door 100 is described, and a flush structure without steps or offsets between the glass 5 and the decorative member 7 is achieved. The track 2 is located on the inner side of the slider 6 (on which the glass 5 moves), and the decorative plate 13 is located on the outer side of the slider 6. The track 2 and the decorative plate 13 are spaced or separated to form an up and down movement structure of the slider 6, thereby moving the glass 5 up and down.

[0078] at the same time, Figure 5 The method of assembling a flush door with a removable slide fixing track is shown. In this case, the direction from which the BIW door 1 is visible from the outside is defined as the outside of the door. The direction from which the BIW door 1 is visible from the inside is defined as the inside of the door.

[0079] As shown in the figure, the flush door assembly method includes: a BIW door and track insertion operation (operation S10) of assembling the track 2 and glass run 3 from the outside of the BIW door 1. The method also includes: an operation of coupling the glass 5 and the slider 6 to the door module 4 from the outside of the BIW door 1 after the door module 4 is installed on the inside of the BIW door (operation S20). The method also includes: an interior component assembly operation (operation S30), an operation of coupling the decorative panel 13 of the decorative member 7 to the inner lip 14 of the glass run from the outside of the BIW door 1 (operation S40), and an operation of coupling the decorative cover 12 of the decorative member 7 to the inner panel cover 9 on the inside of the BIW door 1 (operation S50).

[0080] refer to Figure 6 , the BIW door and track insertion operation (S10) includes: inserting the track 2 into the top frame structure of the door frame 15 from the outside to the inside of the BIW door 1, and then supporting the track 2 by fastening hardware. In addition, the BIW door and track insertion operation (S10) includes: installing the glass run 3 integrated with the frame molding and the fixed glass 3a on the door frame 15 of the BIW door 1 installed with the track 2.

[0081] In particular, the track 2 is used to constrain the guide pin 2a in the positioning hole 15a of the door frame 15, as shown in FIG. Figure 4 shown.

[0082] Furthermore, when the hardware is fastened between the track 2 and the door frame 15, a gasket 17 is attached to prevent the frame from making any noise.

[0083] Next, the glass and slide member combining operation (S20) includes installing or combining the slide member 6 and the integrated glass 5 bonded with the sealant 10 to the door module 4 installed inside the door frame 15. Operation (S20) also includes installing the slide member 6 on the open cross-section structure of the track 2.

[0084] Furthermore, when the slider 6 is inserted into the open cross-section structure of the rail 2 , grease is applied to compensate for friction.

[0085] In addition, the interior component assembling operation (S30) includes: installing each of the outer band 8a and the inner band 8b on the door frame 15 of the BIW door 1, assembling the glass run inner lip 14 in the fastening groove of the rail 2, and assembling the inner panel cover lip 18 on the inner panel cover 9. The operation (S30) also includes: fastening the rail 2 to the door frame 15 using the screws 20, and fastening the rail 2 and the door frame 15 using the screws 20 to fix the rail 2 to the door frame 15.

[0086] As described above, the interior component assembly operation (S30) is an operation for installing the outer band 8a and the inner band 8b, the glass run inner lip 14, the inner panel cover lip 18, the screws 20, etc. However, in an actual assembly process, any one of the BIW door and track insertion operation (S10), the glass and slide member combination operation (S20), the decorative panel combination operation (S40), and the decorative cover combination operation (S50), the components may be performed separately.

[0087] Therefore, the interior component assembly operation (S30) is shown as a separate process operation, but can be described by any one of the BIW door and track insertion operation (S10), the glass and slide member bonding operation (S20), the decorative panel bonding operation (S40) and the decorative cover bonding operation (S50).

[0088] Specifically, in the decorative panel joining operation (S40) and the decorative cover joining operation (S50), the glass run outer lip 11, the decorative cover 12 and / or the decorative panel 13 are constructed as components of the decorative part 7 and are completed by assembling the glass 5, then covering the track 2, and fastening to the BIW door 1 using hardware.

[0089] Specifically, the decorative member 7 is assembled by fitting the glass run outer lip 11 between the decorative cover 12 and the decorative panel 13 .

[0090] For example, in the decorative plate combining operation (S40), in a state where the glass 5 is assembled, the decorative plate 13 is fastened to the door frame 15 of the BIW door 1 using hardware to form a U-shaped cross section by covering the open cross section of the rail 2. In addition, the glass run inner lip 14 is assembled into a fastening groove provided in the airtight portion of the rail 2.

[0091] Therefore, the decorative panel 13 can generate a supporting force to the inside of the vehicle. Figure 3 As shown, the restriction of the decorative member 7 to the door frame 15 can be achieved by inserting the bolt 7 a through the bolt hole 15 b and screwing it into the nut 19 .

[0092] For example, in the decorative cover bonding operation (S50), the decorative cover 12 is bonded to the decorative panel 13 using a double-sided tape, the inner panel cover 9 is bonded to the BIW door 1, and the inner panel cover lip 18 is assembled to the inner panel cover 9. Thus, the BIW door 1 covering the door frame 15 and the door inner panel 16 is completely assembled.

[0093] Therefore, it can be seen that in the method of assembling the flush door, since the components of the BIW door 1 are inserted from the outside to the inside to assemble the flush door 100 during the assembly process of the flush door 100, the assemblability can be significantly improved compared with the conventional modular method of assembling components.

[0094] Furthermore, since the flush door assembly method requires minimal changes to conventional production processes, it can be applied without modifying conventional production lines. Specifically, the flush door assembly method described herein can reduce modularization costs associated with conventional modular production lines and reduce investment costs in production facilities for module assembly, thereby ensuring competitiveness in terms of product cost.

[0095] As described above, in a flush-mounted door with a removable slider fixing track and a flush-mounted door assembly method, the slider 6, which guides the vertical movement of the glass 5 mounted on the door module 4 of the BIW door 1, is surrounded by a U-shaped section formed by the track 2, positioned inside the door frame 15, and a decorative panel 13, positioned outside the door frame. Therefore, the separate structure of the track and decorative components enables in-line assembly. Specifically, this structure allows for component assembly to proceed in the order of track, glass and slider, decorative panel, and decorative components, from the exterior or exterior to the interior or interior, through the separate structure of the track and decorative components. This improves assemblability across various flush-mounted door assembly methods compared to conventional modular assembly methods.

[0096] The present invention has been described above with reference to exemplary embodiments and drawings, but the present invention is not limited thereto. The present invention can be implemented in various forms by a person skilled in the art within the technical spirit of the present invention and the scope of equivalents of the appended claims.
