Description

[Technical Field]

[0001] This invention is used when attaching a door lock member to a vehicle door via a fastener. door This relates to a locking member mounting jig. [Background technology]

[0002] Conventionally, the door lock member is attached to a vehicle door through an opening formed on the inside of the vehicle door for the striker to enter. and This is done by supporting the door lock member at a position where it communicates with the entrance groove (hereinafter simply referred to as the member mounting position), and fastening the door lock member integrally to the vehicle door via a fastener on the outside of the vehicle door.

[0003] The installation work of such a door lock member is extremely cumbersome, requiring a single worker to simultaneously perform two operations: a supporting operation with one hand to accurately position and support the lock member at the member installation position inside the vehicle door, and a tightening operation with the other hand to insert and tighten fasteners into fastening holes that are provided on the door lock member and the vehicle door and communicate with each other at the member installation position, which places a heavy workload on the worker.

[0004] In order to reduce this workload, an installation jig for a door lock member has been proposed that includes an L-shaped main plate bent into an L shape in a plan view, a protrusion protruding from the plate surface on the inside of the short side of the L-shaped main plate, and an insertion hole for a fastener formed through the plate surface on the long side of the L-shaped main plate (see, for example, Patent Document 1).

[0005] With this locking member mounting jig, the L-shaped corner portion is aligned with the corner of the vehicle door and the L-shaped main body plate is attached from the outside. This allows the protrusion to be inserted into the entry groove of the door locking member through the opening of the vehicle door, supporting the door locking member at the member mounting position inside the vehicle door, and the insertion holes are positioned in phase with the fastening holes formed in the vehicle door and the door locking member, respectively, allowing for stable installation of the door locking member to the vehicle door. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-139177 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the above-mentioned conventional lock member mounting jig cannot accommodate general door lock members, and there is a risk that the support state of the door lock member at the member mounting position on the inside of the vehicle door may become unstable or cause rattling, making it difficult to perform accurate mounting work.

[0008] 8(a) to 9(b) show the structure of a general door lock member. Fig. 8(a) and Fig. 8(b) are a schematic side cross-sectional view and a schematic end view of the door lock member in the unlocked state, respectively. 9 (a) and Fig. 9 1(b) is a schematic side cross-sectional view and a schematic end view of the door lock member in the locked state.

[0009] As shown in Figures 8(a) to 9(b), a generally widespread door locking member R has a basic structure comprising: a latch R2 arranged either above or below an entrance groove R10 within a hollow rectangular housing R1, which rotates vertically along the extension direction of the entrance groove R10 and appears and disappears approximately at the center of the width direction of the entrance groove R10 and halfway along the extension direction; and a locking claw R3 arranged either above or below the entrance groove R10, which rotates and displaces to engage with the tip of the latch extending vertically through the entrance groove R10.

[0010] The latch R2 is in the shape of a roughly bifurcated plate with a linear cutout, and as shown in Figures 8(a) to 9(b), it has one engaging piece R21 on the rear side in the entry direction against which the striker S provided on the vehicle main body side abuts, the other engaging piece R22 on the front side in the entry direction that engages with a locking claw R3 provided inside the housing R1, and a striker receiving groove R23 into which the striker S fits between the two engaging pieces R21, R22, and is rotatably attached to a predetermined position inside the housing R1 at the center of the upper part of the bifurcated part via a pivot R24, and is configured to be constantly urged in the unlocking direction by urging means R25 such as a torsion spring so as to be able to move in and out of the entry groove R10.

[0011] That is, as shown in Figures 8(a) and 8(b), the latch R2 in the unlocked state is constantly biased to rotate in the unlocking direction by the biasing means R25, so that one engaging piece R21 is exposed at the rear of the entry groove R10 in the entry direction and approximately in the center of the width direction, and the other engaging piece R22 is buried in the housing R1 at the front of the entry direction.

[0012] On the other hand, as shown in Figures 9(a) and 9(b), the latch R2 in the locked form rotates and displaces against the biasing force of the biasing means R25 as the striker S enters the entrance groove R10, and inserts the striker S into the striker receiving groove R23 between the two engagement pieces R21, R22, leaving the other engagement piece R22 exposed and traversing the entrance groove R10.

[0013] Specifically, as the striker S pushes the one engaging piece R21 inward in the entry direction, the other engaging piece R22, which was in a buried state, moves relatively from inside the housing R1 to be exposed inside the entry groove R10.

[0014] Finally, one engagement piece R21 is pushed all the way to the innermost side of the entry groove R10 and is buried inside the housing R1 at the rear side of the entry groove R10, while the other engagement piece R22 is exposed across the entry groove R10, completing the engagement between the tip of the other engagement piece R22 and the lock claw R3 inside the housing R1, and the latch R2 is locked.

[0015] In this manner, a door lock member of a general structure is configured such that a portion of the latch is always exposed within the entrance groove in both the locked and unlocked positions of the latch.

[0016] In this regard, with the above-mentioned conventional locking member mounting jig, a gap is formed between the long side of the L-shaped main plate and the protrusion into which the other engaging piece that has been rotated and displaced can enter, which may seem to prevent interference with the latch, but this gap is suitable for door locking members with a special structure that has a latch that can appear and disappear along the outermost groove edge portion in the width direction of the entry groove.

[0017] Therefore, the above-mentioned conventional locking member mounting jig is not compatible with widely used locking members, and the protrusion inserted into the entry groove may inadvertently interfere with the latch that is always exposed at approximately the center of the groove in the width direction and halfway in the extension direction, which may result in an unstable support state of the door locking member at the member mounting position on the inside of the vehicle door.

[0018] In other words, if the protrusion is forcibly pushed into the entry groove, the other engaging piece that rotates and becomes exposed and displaced relatively into the groove as the protrusion pushes in one engaging piece of the latch will hit the upper and lower midpoints of the protrusion and press against it, causing the protrusion to be inadvertently clamped and fixed between the protrusion and the groove side surface facing the side where the latch is provided.

[0019] Therefore, the protrusion is prevented from moving further in the depth direction of the entry groove, and the entry distance (fitting amount) of the protrusion into the entry groove becomes insufficient, which deteriorates support and may cause vertical rattle at the component mounting position of the locking member on the inside of the vehicle door via the protrusion.

[0020] As a result, the fastening holes formed in the vehicle door and the door lock member may become misaligned, making it impossible to insert the fasteners, which could hinder the smooth installation of the door lock member on the vehicle door.

[0021] Furthermore, conventional locking member mounting jigs are configured to provide a latch storage space adjacent to the protrusion between the protrusion and the long L-shaped side of the main plate, which reduces the contact area between the protrusion and the opening in the vehicle door and the entry groove of the door locking member.

[0022] In other words, if you try to stably support the door lock member, which is a heavy object, on the inside of the door using the contact point with the opening of the vehicle door as a fulcrum, unless the contact surface of the protrusion that corresponds to the opening of the vehicle door and the entry groove of the door lock member is large, the supportability of the door lock member at the member installation position on the inside of the vehicle door using the jig will be significantly reduced.

[0023] Therefore, when the door lock member and the vehicle door are supported by a conventional jig and the fastener is tightened, the door lock member is subject to the force of the fastener entering from the mounting position on the inside of the vehicle door, and is easily displaced inadvertently. On the side There is a risk that the door lock member cannot be attached in a stable state.

[0024] The present invention has been made in consideration of the above circumstances, and its object is to provide a door lock member mounting jig that improves the support of the door lock member at the member mounting position on the inside of the vehicle door, and enables reliable installation of the door lock member on the vehicle door via a fastener. [Means for solving the problem]

[0025] In order to solve the above-mentioned problems, the present invention provides a door locking device that is used when attaching a door locking member having an entrance groove for a striker corresponding to an opening to a vehicle door having an opening for the striker to the door locking member via a fastener. door A lock member mounting jig, comprising: a gripping portion; a lock member extending from the gripping portion and connected to the opening of the vehicle door; doorand an insertion portion to be inserted and fitted into the entrance groove of the locking member, wherein the insertion portion has upper and lower abutment portions that abut against upper and lower inner edge portions of the opening and upper and lower groove edge portions of the entrance groove at upper and lower surfaces, respectively; a latch avoidance portion that inserts a latch that protrudes and displaces in the vertical direction within the entrance groove as the insertion portion enters the entrance groove to avoid the latch; a stopper portion that abuts at a tip portion an inner edge surface on the back side of the opening in the entrance direction to regulate the entrance position into the entrance groove; and a latch pressing portion that is juxtaposed to the stopper portion in the width direction and that presses the latch in the entrance groove toward the back side in the entrance direction to rotate and displace it while placing it in the striker receiving groove of the latch. door A locking member mounting jig is provided.

[0026] Furthermore, the present invention door The locking member attachment jig is also characterized by the following points (2) to (6). (2) The fitting portion has a base end stopper portion formed on the base end side and abutting against the side surface of the vehicle door near the opening to regulate the position of the fitting portion entering the entrance groove. (3) The insertion portion is provided with a groove insertion portion that is formed to extend along the shape of the entry groove and that fits into the entry groove, and an opening insertion portion that is adjacent to the groove insertion portion in the width direction, that is formed to extend further toward the tip than the groove insertion portion, and that is formed to extend along the shape of the opening and that fits into the groove insertion portion, the tip of the opening insertion portion is configured as the stopper portion, and the tip of the groove insertion portion is configured as a latch pressing portion that pushes the latch into a position that maintains the unlocked state. (4) The latch avoidance portion is a latch avoidance hole formed by penetrating vertically at the midpoint of the insertion portion. (5) The insertion portion is provided with a positioning plate that faces the end surface of the vehicle door, through which a fastening hole for inserting the fastener is formed, when inserted into the opening and the entry groove, and the positioning plate has a predetermined thickness and is provided with a plate surface facing one side of the insertion portion in the width direction, and an insertion hole for fastener countersinking is formed by passing through the plate surface at a position on the plate surface corresponding to the fastening hole of the vehicle door. (6) The positioning plate has a door contact portion that projects from the outer periphery of the plate surface and contacts the end surface of the vehicle door in a face-to-face relationship. [Effects of the Invention]

[0027] According to the invention of claim 1, a door lock member having an entrance groove for a striker corresponding to an opening for the striker to be attached to a vehicle door via a fastener. door A lock member mounting jig, comprising: a gripping portion; a lock member extending from the gripping portion and connected to the opening of the vehicle door; door and an insertion portion to be inserted into the entrance groove of the locking member, the insertion portion having upper and lower abutment portions at its upper and lower surfaces that respectively abut against the upper and lower inner edge portions of the opening and the upper and lower groove edges of the entrance groove; a latch avoidance portion at its midpoint that passes through and avoids a latch that protrudes and displaces up and down within the entrance groove as the insertion portion enters the entrance groove; a stopper portion at its tip that abuts against the inner edge surface at the back side of the opening in the entrance direction to regulate the entry position into the entrance groove; and a latch pressing portion that is juxtaposed to the stopper portion in the width direction and that presses and pivotally displaces the latch in the entrance groove back side in the entrance direction while placing it in the striker receiving groove of the latch. This makes it possible to firmly and stably support the door lock member at a member attachment position on the inside of the vehicle door, and effectively assists the installation work of the door lock member to the vehicle door using a fastener, thereby improving workability.

[0028] In other words, when the fitting portion is fitted into the opening and the entry groove, the upper and lower abutment portions that abut against the opening of the vehicle door serve as fulcrum portions, and the upper and lower abutment portions that abut against the entry groove of the door lock member function as support action points that stabilize the lock member in the member mounting position.

[0029] In other words, the fitting portion has abutment portions that are always in contact with the upper and lower parts of the opening and the entry groove when fitted, and performs a fitting function of fixing the vehicle door and the locking member together by expanding the contact area as much as possible at the joint between the separate vehicle door and the locking member.

[0030] In this way, the vehicle door and the door lock member are fixed integrally at the member mounting position without causing positional deviation, improving the supportability of the door lock member on the vehicle door and enabling the lock member to be firmly supported on the vehicle door at the same position.

[0031] In addition, the stopper portion formed at the tip restricts the position at which the insertion portion enters the insertion groove, making it easy to insert the insertion portion via the grip portion, thereby improving workability.

[0032] In addition, the latch pressing portion at the tip of the insertion portion pushes the latch in the entry groove all the way to the back and rotates it while placing it in the striker receiving groove of the latch, and the latch avoidance portion at the middle portion can be inserted to avoid the latch that is protruding and displacing into the entry groove, thereby achieving stable support without inadvertently reducing the contact area between the upper and lower abutment portions and the entry groove.

[0033] As a result, not only door lock members with a basic structure but also lock members with special structures can be fitted well into the opening and entry groove of the insertion portion, ensuring solid support of the door lock member on the vehicle door.

[0034] Furthermore, even when subjected to fastening stress accompanying the tightening operation of the fastener, the latch pressing portion is positioned in the striker receiving groove of the latch, so the door lock member does not rattle or shift from the member mounting position inside the vehicle door, and the door lock member can be stably fastened and fixed to the vehicle door.

[0035] In other words, by using this jig to hold the door lock member at the member installation position inside the vehicle door, it is possible to eliminate the need for the worker to support the member, thereby reducing labor and workload. Anyone can easily and stably perform the tightening operation to screw in and fasten the member, which has the effect of improving the robustness of the vehicle door after the door lock member has been installed.

[0036] Furthermore, according to the invention of claim 2, the insertion portion has a base end stopper portion formed on the base end side that abuts against the side surface of the vehicle door near the opening and regulates the insertion position into the insertion groove. This improves the operability of the jig and further improves the function of integrally supporting and fixing the locking member to the vehicle door via the jig.

[0037] According to the invention of claim 3, the fitting portion is formed along the shape of the entrance groove. Te form and a groove insertion portion that is adjacent to the groove insertion portion in the width direction and extends further toward the tip end than the groove insertion portion. and Both are formed to extend along the shape of the opening and are provided with an opening insertion portion that fits into the opening, and the tip of the opening insertion portion is configured as the stopper portion, while the tip of the groove insertion portion is configured as a latch pressing portion that pushes the latch into a position that maintains the unlocked state, thereby further improving the function of this jig in integrally supporting and fixing the locking member to the vehicle door.

[0038] That is, the groove insertion portion contacts and fits into the entry groove of the locking member at the upper and lower abutment portions, and the opening insertion portion, which is formed to extend longer than this, contacts and fits into the opening of the vehicle door at the upper and lower abutment portions and also abuts against the inner edge of the opening of the vehicle door at the stopper portion at the tip, thereby improving the fit of this jig with both the vehicle door and the locking member.

[0039] Furthermore, since the opening insertion portion is formed to extend further toward the tip than the groove insertion portion, when the stopper portion at the tip of the opening insertion portion abuts the inner edge portion at the back of the opening, the latch pressure portion at the tip of the groove insertion portion forms a certain clearance space relative to the innermost side of the entry groove, thereby restricting further entry.

[0040] In other words, one engaging piece, which is pressed and moved by the latch pressing portion, is not pushed all the way to the "innermost side of the entry groove" where the other engaging piece, which moves along with it, engages with the locking claw, but is stopped in the clearance space just before that, thereby maintaining the latch in an unlocked state.

[0041] In other words, the stopper portion that protrudes further toward the tip than the latch pressing portion regulates the movement distance of the one engaging piece portion and the relative movement distance of the other engaging piece portion so that the entry position within the entry groove of the latch pressing portion is a position where the other engaging piece portion stops just before the latch claw.

[0042] This means that after the door lock member, which is integrally supported and fixed to the vehicle door with this jig, is tightened using a fastening device, the jig can be pulled out from the opening of the vehicle door and the entry groove of the door lock member without the latch interfering with the jig, thereby reducing the workload.

[0043] Furthermore, according to the invention of claim 4, the latch avoidance portion is a latch avoidance hole formed by penetrating vertically at the middle of the insertion portion, so that the latch pressing portion at the tip is supported via the left and right side wall portions of the latch avoidance hole to ensure rigidity, and the upper and lower surface portions of both side wall portions serve as upper and lower abutment surfaces arranged in the width direction, thereby maintaining good fit with the entry groove and opening.

[0044] Furthermore, by adjusting the distance between the front and rear walls of the latch avoidance hole to a distance that interferes with the rotational trajectory of the other engaging piece of the rotating latch, the latch avoidance hole can be made to abut against either the front or rear wall while accommodating the tip of the other engaging piece, thereby functioning as a rotation stopper that restricts further rotational displacement of the latch and prevents it from engaging with the latch claw.

[0045] Furthermore, since the door lock member is integrally supported on the vehicle door with the other engaging piece of the latch housed in the latch avoidance hole, the latch engages with the latch avoidance hole when subjected to the entry stress of the fastener, allowing for stable fastening operations.

[0046] According to the invention of claim 5, the insertion portion includes a positioning plate that, when inserted into the opening and the entrance groove, faces the end surface of the vehicle door through which fastening holes for inserting the fasteners are formed, and the positioning plate has a predetermined thickness and is provided with a plate surface facing one side of the insertion portion in the width direction, and through holes for countersinking the fasteners are formed through the plate surface at positions corresponding to the fastening holes in the vehicle door.Therefore, when the insertion portion is inserted to integrally support and fix the door lock member to the vehicle door, the insertion holes align the axes of the fasteners with the axes of the fastening holes, thereby performing a centering function that allows the fasteners to be inserted straight into each fastening hole, allowing for accurate fastening operations.

[0047] That is, stable fastening operation can be performed without cutting the countersunk portion where the head of the fastener enters the fastening hole of the vehicle door, reducing the number of steps, and also improving convenience when the vehicle door is made of a material that is not suitable for cutting (for example, aluminum). Therefore, there is an effect that it is possible to prevent the fastener from accidentally shifting from the fastening hole position during the fastening operation and gouging or scratching the exterior surface of the vehicle door, which could cause scratches on the painted surface.

[0048] Furthermore, according to the invention of claim 6, the positioning plate has a door abutment portion that protrudes from the outer peripheral edge of the plate surface and abuts against the end surface of the vehicle door in a face-to-face manner. This reduces the contact area between the positioning plate and the vehicle door as much as possible, thereby preventing as much as possible the generation of inadvertent friction between the positioning plate and the vehicle door when inserting and removing the jig into and from the opening of the vehicle door and the entry groove of the door lock member, and has the effect of preventing scratches on the painted surface.

[0051] The fitting portion is characterized in that it has a base end stopper portion formed on the base end side and abuts against the side surface of the vehicle door near the opening to regulate the position at which the fitting portion enters the entrance groove.

[0052] The fitting portion is formed to extend along the shape of the entrance groove, and includes a groove insert portion that fits into the entrance groove, and is adjacent to the groove insert portion in the width direction and extends further toward the tip than the groove insert portion. and Both are formed to extend along the shape of the opening and have an opening insertion portion that fits into it, and the tip of the opening insertion portion is configured as the stopper portion, and the tip of the groove insertion portion is configured as a latch pressing portion that pushes the latch into a position that maintains the unlocked state.

[0053] The latch avoidance portion is characterized in that it is a latch avoidance hole formed in the middle of the fitting portion so as to penetrate in the vertical direction.

[0054] The insertion portion is provided with a positioning plate that faces the end surface of the vehicle door, through which a fastening hole for inserting the fastener is formed, when inserted into the opening and the entry groove, and the positioning plate has a predetermined thickness and is provided with a plate surface facing one side of the insertion portion in the width direction, and is characterized in that a through hole for countersinking the fastener is formed by passing through the plate surface at a position on the plate surface corresponding to the fastening hole of the vehicle door.

[0055] The positioning plate is characterized in that a door abutment portion that abuts against the end surface of the vehicle door in a face-to-face relationship is formed by projecting from the outer periphery of the plate surface.

[0056] The locking member mounting jig according to the present invention will be described below. toIn the following description, unless otherwise specified, the terms "upper and lower sides" refer to the upper and lower sides of the vehicle door (upper and lower sides based on the opening of the vehicle door and the entry groove of the door lock member), and the terms "front side" and "rear side" refer to the interior side and the exterior side in the width direction of the vehicle door (the front side and rear side based on the longitudinal direction of the opening of the vehicle door through which the striker enters and the entry groove of the door lock member). In addition, in the following embodiment, a configuration in which the door lock member is attached to a right front door will be described as an example of the vehicle door, but it goes without saying that the present invention can also be applied to a left front door or left or right rear door of the vehicle.

[0057] [1. Vehicle door and door lock member, door Overview of the locking member mounting jig FIG. 1 is a diagram illustrating the configuration of the present invention. door 1 is a schematic explanatory diagram showing an example of use of a locking member installation jig. A generally widespread hollow vehicle door D has an opening D10 at a free end corner D1a on the passenger compartment side for a striker S provided on the vehicle body side to enter, as shown in Fig. 1. The striker S is composed of an engaging rod bent into a U-shape and protrudes at a predetermined position on the inner edge of the boarding opening on the vehicle body side.

[0058] The opening D10 is formed by cutting out an approximately rectangular shape horizontally at a predetermined position in the vertical direction of the corner D1a, and is an L-shaped opening surrounded by upper and lower inner edge portions D11, D11' that are L-shaped in a plan view, a front inner edge portion D12 located on the interior side of the vehicle door D, and a rear inner edge portion D13 located on the outside of the vehicle door D.

[0059] That is, as shown in Figure 1, the opening D10 has an L-shape in a plan view, with a short opening D101 opening on one side D1b of the vehicle door D on the interior side, and a long opening D102 opening on the end face D1c of the vehicle door D, and is connected to the internal space of the vehicle door D.

[0060] The short opening D101 is an approximately C-shaped window-shaped portion that opens to the end of the vehicle door D when viewed from one side of the interior of the vehicle door D, and is located at the front end in the direction of entry of the striker S, that is, at the beginning of the long opening D102 when viewed from the end of the vehicle door D.

[0061] The longitudinal opening D102 is a generally U-shaped window portion that opens toward the interior side of the vehicle door D in an end view of the vehicle door D, and the upper and lower opening widths are gradually narrowed from the inside to the outside in the width direction of the vehicle door D (along the entry direction of the striker S). In other words, the upper and lower inner edge portions D11, D11' of the longitudinal opening D102 are gradually brought closer to each other from the front side to the back side, thereby narrowing the upper and lower opening widths.

[0062] Further, a plurality of fastening holes D14 for inserting the fastener B are formed in the end surface D1c of the vehicle door D at positions above and below the opening D10. In this embodiment, the fastening holes D14 are formed in the end surface D1c of the vehicle door D, one at an upper position and two at lower positions on the left and right sides, with the opening D10 as the boundary.

[0063] As shown in Fig. 1, a door lock member R that engages with a striker S on the vehicle body side is fixed to the inside of the opening D10 of such a vehicle door D. As shown in Figs. 1 and 8(a) to 9(b), the door lock member R, like the vehicle door D, has an entrance groove R10 formed at a predetermined position in the vertical direction at a corner of a substantially rectangular housing R1, into which the striker S provided on the vehicle body side enters.

[0064] The entry groove R10 corresponds to and communicates with the opening D10 of the vehicle door D, and is formed by cutting out one corner of the housing R1 horizontally in an approximately rectangular shape along the entry direction of the striker S, as a space portion that is U-shaped in vertical cross section and is open to the end face D1c side and one side face D1b side of the vehicle door D installed therein.

[0065] Specifically, the entry groove R10 is formed as a U-shaped space portion surrounded by upper and lower side walls R11, R11' which correspond to the upper and lower horizontal sides of the U-shape in cross section and extend longitudinally along the entry direction of the striker S, and a horizontal side wall R12 which corresponds to the vertical side of the U-shape in cross section and extends longitudinally along the entry direction of the striker S between one ends of the upper and lower side walls R11, R11' in the groove width direction.

[0066] In other words, the door lock member R has a groove opening R10a surrounded by an L-shaped groove edge that is approximately the same as the opening D10 of the vehicle door D opened by the entrance groove R10, and a short opening R101 that opens on one side surface R1b that is inscribed in one side surface D2 of the vehicle door D, and a long opening R102 that opens on an end surface R1c that is inscribed in an end surface D1c of the vehicle door D are formed along the corner of the housing R1.

[0067] In particular, the entrance groove R10 of the door lock member R of this embodiment is formed so that the upper and lower groove widths gradually narrow along the entrance direction of the striker S, similar to the opening D10 of the vehicle door D. In other words, in a vertical cross-sectional view, the entrance groove R10 has upper and lower side walls R11, R11' that gradually approach each other from the front side to the back side, thereby narrowing the upper and lower groove widths.

[0068] 1 and 8(a) to 9(b), a plurality of fastening holes R13 for inserting fasteners B corresponding to the fastening holes D14 of the vehicle door D are formed in the end face R1c of the door lock member R at positions above and below the entrance groove R10. That is, the fastening holes R13 of this embodiment are formed in the end face R1c of the housing R1 of the door lock member R, with one fastening hole R13 at an upper position and two fastening holes R13 on the left and right sides below the entrance groove R10.

[0069] The fastener B is not particularly limited as long as it can firmly fasten and fix the door lock member R to the vehicle door D, and may be a rivet or a bolt with a threaded surface that has a head B1 for fastening operation and a body B2 that joins each component and has a smooth peripheral surface. In this embodiment, a bolt is used.

[0070] As shown in the above-mentioned Figures 1 and 8(a) to 9(b), the door lock member R is configured to include a latch R2 that is arranged above the entry groove R10 within the housing R1, that rotates vertically along the extension direction of the entry groove R10, and that appears and disappears approximately at the center in the width direction of the upper wall R11 that forms the entry groove R10 and halfway along the extension direction, and a lock claw R3 that is arranged below the entry groove R10, that rotates and displaces vertically across the entry groove R10, and that engages with the tip of the latch that is below the lower wall R11' that forms the entry groove R10.

[0071] In addition, latch ingress / egress holes are formed in the upper and lower side walls R11, R11' of the entry groove R10 on the rotational trajectory of the latch R2 pivotally mounted within the housing R1, allowing the pivotally displaced latch R2 to move in and out of the entry groove R10 in a longitudinal direction.

[0072] As shown in Fig. 1 and Figs. 8(a) to 9(b), the latch R2 is a generally bifurcated plate with a linear cutout in one portion, and has one engaging piece R21 on the far side in the entry direction against which the striker S provided on the vehicle body abuts, and a locking claw provided in the housing R1. R3 and a striker receiving groove R23 between the two engaging pieces R21, R22.

[0073] The latch R2 is rotatably mounted via a pivot R24 at a predetermined position within the housing R1 in the central portion of the upper fork, and is constantly biased in the unlocking direction by a biasing means R25 such as a torsion spring, allowing it to enter and exit the entry groove R10.

[0074] In the vehicle door D and the door lock member R having such a structure, door As shown in FIG. 1, the lock member mounting jig A is configured to firmly support the door lock member R at the mounting position on the inside of the vehicle door D, with the entrance groove R10 positioned in phase with the opening D10.

[0075] In other words, the jig A of the present invention holds the door lock member R at the member installation position inside the vehicle door D, eliminating the need for the worker to support it, reducing labor and reducing the workload, and allowing anyone to easily and stably perform the tightening operation of screwing and fastening, thereby improving the robustness of the vehicle door after the door lock member has been installed.

[0076] [2. Locking member mounting jig according to the first embodiment] A locking member installation jig according to a first embodiment of the present invention will be described below with reference to the drawings. Figures 2(a) and 2(b) are rear and front perspective views, respectively, showing the configuration of the jig. Figures 3(a) and 3(b) are plan and side views, respectively, showing the configuration of the jig. Figures 4(a) and 4(b) are schematic side views, respectively, showing the state before and after insertion of the jig into the opening of a vehicle door. Figures 5(a) and 5(b) are schematic side views, respectively, showing the state before and after insertion of the jig into the entrance groove of a door locking member. Figures 6(a) and 6(b) are explanatory views showing the operation of fastening a fastener using a positioning plate.

[0077] According to this embodiment door The locking member mounting jig A1 has a generally T-shaped overall appearance as shown in Figures 2(a) to 3(b), and is composed of a gripping portion 1 for an operator to grip and operate, and an insertion portion 2 extending from the gripping portion 1 and inserted into an opening D10 of the vehicle door D, which is in a connected state, and an entry groove R10 of the door locking member R.

[0078] The gripping portion 1 corresponds to the horizontal side of the T-shaped appearance of the jig A1, and is a substantially straight square bar with a predetermined thickness, with a fitting portion 2 extending perpendicularly from a central portion 11 in the longitudinal direction.

[0079] 2(a) to 3(b), grip portions 10, 10' are formed on the left and right sides of the central portion 11 of the handle 1 to make it easier for the operator to grasp. The grip portions 10, 10' are formed as semicircular recesses on the left and right sides of the central portion of the connection with the inserting portion 2 on one longitudinal side surface 1a from which the inserting portion 2 extends.

[0080] This allows the grip to be improved by placing the palm of the hand on the other longitudinal side surface 1b opposite the one longitudinal side surface 1a and placing four curled fingers, thereby improving the operability of inserting and removing the insertion portion 2 into the opening D10 and entry groove R10 via the gripping portion 1.

[0081] As shown in FIGS. 2(a) to 3(b), the fitting portion 2 corresponds to the central vertical side of the T-shaped appearance of the jig A1, and has a substantially elongated wedge-shaped rectangular bar shape that conforms to the opening shape of the opening D10 of the vehicle door D and the groove shape of the entrance groove R10 of the door lock member R. to 0 It is formed to fit together.

[0082] The width of the fitting portion 2 is formed to be approximately the same as the width of the opening D10 (the left and right opening width of the short opening D101), i.e., the width of the entrance groove R10 (the left and right opening width of the short opening R101). Also, the length of the fitting portion 2 is the longitudinal side of the opening D10 (the front and rear opening width of the long opening D102), i.e., the longitudinal side of the entrance groove R10 (the front and rear opening width of the long opening R102). Front and rear The thickness of the fitting portion 2 is set to be approximately the same as the vertical width of the opening D10, that is, the vertical width of the entrance groove R10.

[0083] That is, the fitting portion 2 is tapered so that its vertical width gradually narrows from the base end to the tip end in accordance with the vertical widths of the opening D10 and the entry groove R10, enabling it to fit tightly into the opening D10 of the vehicle door D and the entry groove R10 of the door lock member R.

[0084] In other words, the fitting portion 2 has a thick base end, and when it is inserted into the opening D10 and the entry groove R10, the thick base end is positioned to span the opening D10 at the joint between the vehicle door D and the door lock member R inside it and the short opening R101 of the entry groove R10 of the door lock member R, thereby improving the rigidity as a fulcrum portion and providing good support for the door lock member R within the vehicle door D.

[0085] The fitting portion 2 has upper and lower contact portions 3, 3' that respectively contact the upper and lower inner edge surfaces (upper and lower inner edge portions D11, D11') of the opening D10 and the upper and lower groove opening edge portions (upper and lower side walls R11, R11') of the entry groove R10. That is, the fitting portion 2 is configured to be disposed across substantially the entire boundary between the adjacent upper and lower inner edge portions D11, D11' and the groove edge portion R10a in the opening D10 of the vehicle door D and the entry groove R10 of the door lock member R that are in a communicating state.

[0086] Specifically, the fitting portion 2 is as shown in FIG. sea ​​urchin The container has wide upper and lower side walls 2a, 2a' that extend longitudinally, and wide left and right side walls 2b, 2b' that extend longitudinally and face each other at the left and right ends of the upper and lower side walls 2a, 2a'.

[0087] The outer surfaces of the left and right side walls 2b, 2b' of the insertion portion 2 are formed as flat surfaces, and the outer surfaces of the upper and lower side walls 2a, 2a' of the insertion portion 2 form upper and lower flat surface portions 20a, 20a' on the base end side and upper and lower inclined surface portions 20b, 20b' on the tip end side.

[0088] That is, as shown in Figures 3(a) and 3(b), the fitting portion 2 has upper and lower abutment portions 3, 3' formed on the outer surfaces of the upper and lower side walls 2a, 2a' by upper and lower flat surface portions 20a, 20a', whose upper and lower surfaces are parallel and whose substantially rear half on the base end side have the same width when viewed from the side, and upper and lower inclined surface portions 20b, 20b', whose substantially front half on the tip end side gradually narrows in width toward the tip end and whose upper and lower surfaces are close together toward the tip end.

[0089] The insertion portion 2 is also configured to have a latch avoidance portion 4 at its midpoint that inserts and avoids the latch that protrudes and displaces vertically within the entry groove R10 as it enters the entry groove R10, a stopper portion 5 at its tip that abuts against the inner edge surface portion (rear inner edge portion D13) on the rear side of the opening D10 in the entry direction to regulate the entry position into the opening D10 and the entry groove R10, and a latch pressing portion 6 that is juxtaposed to the stopper portion 5 in the width direction and that pushes the latch R2 of the entry groove R10 toward the rear side in the entry direction to rotate and displace it while placing it in the striker receiving groove R23 of the latch R2.

[0090] The latch avoidance portion 4 may be formed on the upper and lower surfaces of the middle portion of the insertion portion 2 so as to be able to insert and avoid the other engaging piece portion R22 of the latch R2 that protrudes and displaces in the vertical direction within the entry groove R10, and may be formed, for example, as a recess or a notch.

[0091] In other words, the latch avoidance portion 4 is formed to have a front-to-back length and left-to-right width that allows at least the tip portion of the other engaging piece portion R22 to be inserted, and is formed to correspond to the upper and lower surface portions of the insertion portion 2 that interfere with the rotational trajectory of the other engaging piece portion R22 of the latch R2 as it rotates and displaces into the entry groove R10.

[0092] 2(b) to 3(b), the latch avoidance portion 4 of this embodiment is a latch avoidance hole 40 formed by penetrating vertically in the middle of the fitting portion 2. The latch avoidance hole 40 is a through-hole that is rectangular in plan view and is formed by penetrating vertically in the center of the width direction of the front half of the fitting portion 2.

[0093] Furthermore, the front-to-back length of the latch avoidance hole 40 is greater than or equal to the front-to-back length of the other engaging piece portion R22 along the rotational trajectory of the pivotally displaced latch R2, and the left-to-right width of the latch avoidance hole 40 is greater than or equal to the thickness of the other engaging piece portion R22.

[0094] This allows the insertion portion 2 to avoid the latch R2 by inserting the other engagement piece R22 of the latch R2 that has been pivotally displaced into the latch avoidance hole 40, and also allows the upper surfaces of the left and right side wall portions 40a, 40a' of the latch avoidance hole 40 to function as upper and lower abutment portions 3, 3', thereby maintaining good fit of the insertion portion 2 with the opening D10 and entry groove R10.

[0095] 2(b) to 3(b), the latch avoidance portion 4 is formed in the middle of the fitting portion 2, thereby forming a latch pressing portion 6 at the tip of the fitting portion 2. That is, the latch avoidance portion 4 and the latch pressing portion 6 are arranged in the same phase at approximately the center in the width direction of the fitting portion 2 to correspond to the latch R2 in the entrance groove R10, and are formed adjacent to each other at the front and rear of the fitting portion 2 in the extension direction.

[0096] The latch pressing portion 6 has a width equal to or less than the groove width of the striker receiving groove R23 and is formed as a generally cylindrical groove insertion shaft 60 extending in the width direction of the fitting portion 2. In other words, the latch pressing portion 6 is integrally supported at its tip end by the left and right side wall portions 40a, 40a' of the hole peripheral wall of the latch avoidance hole 40.

[0097] The groove insertion shaft 60 functions as a pseudo striker S, extending parallel to the axial direction of the pivot R24 of the latch R2, and is configured to abut against the one engagement piece R21 exposed in the entrance groove R10, move it toward the rear, and be inserted into the striker receiving groove R23 of the latch R2.

[0098] As shown in FIGS. 4(a) to 5(b), the fitting portion 2 is formed to extend along the shape of the entrance groove R10, and includes a groove insertion portion 200 that abuts on the upper and lower surfaces of the entrance groove R10 and fits into the entrance groove R10, and a groove insertion portion 200 that is adjacent to the groove insertion portion 200 in the width direction and extends further toward the tip than the groove insertion portion 200. and Both are formed to extend along the shape of the opening D10, and are configured with an opening insertion portion 210 that abuts against the opening D10 from above and below to fit into the opening D10.

[0099] In other words, the insertion portion 2 is configured to function as a fulcrum for the opening insertion portion 210, which corresponds to be inserted into the opening D10 of the vehicle door D, and also as a point of action for stably supporting the groove insertion portion 200, which corresponds to be inserted into the entry groove R10 of the door lock member R, at the member mounting position.

[0100] In other words, as shown in Figures 4(a) to 5(b), the upper and lower abutment portions 3, 3' in the fitting portion 2 are composed of opening abutment portions 30, 30' formed on the upper and lower surfaces of the opening insertion portion 210 and abutting against the upper and lower inner edge portions D11, D11' along the longitudinal opening D102 of the opening D10 of the vehicle door D, and groove abutment portions 31, 31' formed on the upper and lower surfaces of the groove insertion portion 200 and abutting against the upper and lower inner edge portions D11, D11' along the longitudinal opening D102 of the opening D10 of the vehicle door D and the upper and lower side walls R11, R11' of the entry groove R10 of the door lock member R.

[0101] The opening insertion portion 210 abuts against upper and lower inner edge portions D11, D11' along the longitudinal opening D102 of the opening D10 of the vehicle door D, as well as upper and lower inner edge portions of the longitudinal opening R102 of the opening R10a of the entrance groove R10 adjacent thereto. In other words, the opening insertion portion 210 is disposed across the boundary between the longitudinal opening D102 of the opening D10 and the longitudinal opening R102 of the entrance groove R10.

[0102] The groove insertion portion 200, together with upper and lower inner edge portions D11, D11' along the longitudinal opening D102 of the opening D10 of the vehicle door D at its base end, abuts against upper and lower inner edge portions of the adjacent short opening R101 of the opening R10a of the entrance groove R10. In other words, the opening insertion portion 200 is disposed across the boundary between the short opening D101 of the opening D10 and the short opening R101 of the entrance groove R10.

[0103] As shown in Figures 2(a) to 4(b), the groove insertion portion 200 is formed wide to match the width of the entry groove R10, and has a latch avoidance portion 4 (latch avoidance hole 40) formed in the middle portion and a latch pressing portion 6 formed at the tip portion adjacent to the latch avoidance portion 4.

[0104] Furthermore, the opening insertion portion 210 has a tip end formed on the stopper portion 5 that extends further to the tip side than the latch pressing portion 6. In other words, the stopper portion 5 is formed by overhanging further to the tip side than the latch pressing portion 6 by extending the opening insertion portion 210 further than the groove insertion portion 200 based on the joint portion with the gripping portion 1.

[0105] As a result, when the stopper portion 5 at the tip of the opening insertion portion 210 abuts against the inner edge surface portion (rear inner edge portion D13) of the opening D10, as shown in Figure 5(b), the latch pressing portion 6 at the tip of the groove insertion portion 200 forms a certain clearance space relatively to the innermost part of the entry groove R10, thereby preventing further entry.

[0106] In other words, one engaging piece R21 of the latch R2, which is pressed and moved by the latch pressing portion 6, is not pushed all the way to the "innermost side of the entrance groove" where the other engaging piece R22, which moves along with it, engages with the locking claw R3, but is stopped in the clearance space just before that, thereby maintaining the unlocked state of the latch R2.

[0107] In other words, the stopper portion 5, which protrudes further toward the tip side than the latch pressing portion 6, regulates the movement distance of the one engaging piece portion R21 and the movement distance of the other engaging piece portion R22 relative to it so that the entry position within the entry groove of the latch pressing portion 6 is a position where the other engaging piece portion stops just before the latch claw.

[0108] In this way, the tip of the opening insertion portion 210 is configured as a stopper portion 5, and the tip of the groove insertion portion 200 is configured as a latch pressing portion 6 that pushes the latch R2 to a position where it maintains the unlocked state.

[0109] As a result, after the door lock member R, which is integrally supported and fixed to the vehicle door D by the jig A1, is fastened by the fastener B, the latch R2 is fastened by the jig A1. 1 This allows the jig A1 to be removed from the opening D10 of the vehicle door D and the entrance groove R10 of the door lock member R without interfering with the door D.

[0110] As shown in Figures 2(a) to 3(b), 6(a) and 6(b), when the insertion portion 2 is inserted into the opening D10 and the entry groove R10, a positioning plate 7 is provided facing the end surface D1c of the vehicle door D, through which a fastening hole D14 for inserting the fastener B is formed, with the plate surface direction perpendicular to the extension direction of the insertion portion 2.

[0111] The positioning plate 7 is an approximately rectangular plate made of transparent resin with a predetermined thickness, and is provided on one side of the insertion portion 2 in the width direction with the plate surface 7a facing each other. A plurality of through holes 70 for countersinking the fastener B are formed through the plate surface at positions corresponding to the fastening holes D14 of the vehicle door D.

[0112] As shown in Figures 3(a) and 3(b), the positioning plate 7 is attached to the outer surface of the opening insertion portion 210 in the insertion portion 2 along approximately the center in the longitudinal direction, and has one insertion hole 70 formed in the upper half and two insertion holes 70 on the left and right in the lower half, with the center portion as the boundary.

[0113] Each insertion hole 70 is a circular hole with an inner diameter substantially the same as the outer diameter of the head B1 of the fastener B, and is formed so that the head B1 of the fastener B fits into it. The peripheral surface of the insertion hole 70 is formed into a tapered peripheral surface 71 that gradually reduces the inner diameter of the insertion hole 70 along the direction in which the fastener B enters.

[0114] Specifically, as shown in Figure 6(b), the insertion hole 70 has a tapered portion 72 formed by a tapered peripheral surface 71 in the outer half of the positioning plate 7 along the insertion direction of the fastener B when viewed in cross section, and a head fitting portion 73 into which the head of the fastener B fits in the inner half of the positioning plate 7.

[0115] 6(b), when the insertion plate 7 is inserted into the opening D10 and the entrance groove R10 of the fitting portion 2, the positioning plate 7 faces the end surface D1c of the vehicle door D, and the insertion holes 70 formed in the positioning plate 7 are positioned in the same phase and coaxial with the fastening holes D14, R13 that are in communication with each other.

[0116] Furthermore, since the positioning plate 7 is made of transparent resin, it is easy to align (position) the insertion hole 70 of the positioning plate 7 with the fastening hole D14 of the end face D1c of the vehicle door D below it, making it possible to check for insufficient insertion of the insertion portion 2 or misalignment of the insertion position.

[0117] That is, when fastening the fastening hole D14 of the vehicle door D and the fastening hole R13 of the door lock member R using the fastener B, as shown in Figures 1, 6(a) and 6(b), the insertion hole 70 allows the axis of the fastener B to be positioned correctly so that it is aligned with the hole axis of each fastening hole D14, R13, and the fastener B can be inserted straight into each fastening hole D14, R13.

[0118] Furthermore, since each insertion hole 70 is formed with a tapered portion 72 and a head fitting portion 73, it functions as a countersink that corrects the posture of fastener B to the correct position as fastener B enters each fastening hole D14, R13, aligning the entry direction of fastener B with the axial direction of each fastening hole D14, R13.

[0119] In particular, when the material of the vehicle door D is unsuitable for cutting, such as aluminum, it is difficult to countersink the fastening hole D14 of the vehicle door D where the head of the fastener B is located, so convenience is improved by fastening the fastener B through the insertion hole 70 of the positioning plate 7 of the jig A1.

[0120] Therefore, it is possible to prevent the fastener B from accidentally shifting from the fastening hole position during the fastening operation, gouging or scratching the end face D1c of the vehicle door D and causing scratches on the painted surface.

[0121] As shown in FIG. 6(b), the positioning plate 7 has a door contact portion 74 that projects from the outer periphery of the plate surface and comes into face-to-face contact with the end surface D1c of the vehicle door D.

[0122] The door abutment portion 74 is configured so that, when the insertion portion 2 is inserted into the opening D10 and the door lock member R, the upper end surface 75a of the flange 75 extending from the outer peripheral edge of the positioning plate 7 parallel to the axis of the insertion hole 70 abuts against the end surface D1c of the vehicle door D.

[0123] This reduces the contact area between the positioning plate 7 and the vehicle door D as much as possible, thereby preventing as much as possible the generation of inadvertent frictional force between the positioning plate 7 and the vehicle door D when inserting and removing the jig A1 into the opening D10 of the vehicle door D and the entry groove R10 of the door lock member R.

[0124] In other words, the plate surface direction of the positioning plate 7 is perpendicular to the extension direction of the insertion portion 2, i.e., the direction of entry into the opening D10 of the vehicle door D, so the area of ​​contact with the end face D1c of the vehicle door D is made as small as possible, thereby preventing scratches on the painted surface.

[0125] This is how it was configured door The lock member mounting jig A1 is used as follows when mounting the door lock member R on the vehicle door D. First, the worker inserts the door lock member R into the vehicle door D with one hand and positions the entrance groove R10 of the door lock member R in phase with the opening D10 on the inside of the vehicle door D.

[0126] Specifically, as shown in FIG. 1, the outer surface of the corner of the housing R1 of the door lock member R is brought into face contact with the inner surface of the corner D1 of the vehicle door D, and the short opening R101 and the long opening R102 of the entrance groove R10 are positioned in the short opening D101 and the long opening D102 that form the opening D10, respectively, so that the opening D10 and the entrance groove R10 are in a connected state.

[0127] Next, the worker inserts the jig A1 into the opening D10 and the entry groove R10, which are maintained in a connected state, by inserting the insertion portion 2 via the gripping portion 1 held with the other hand from the inside to the outside in the width direction of the vehicle door D.

[0128] Specifically, as shown in Figures 1 and 4(a) to 5(b), the insertion portion 2 on the tip side of the gripping portion 1 is inserted from the short opening D101 of the vehicle door D facing the interior side of the vehicle door D and the short opening R101 of the entry groove R10 of the door lock member R, along the extension direction of each longitudinal opening D102, R102, to the back side of the opening D10 and the entry groove R10.

[0129] As the insertion portion 2 enters the entry groove R10, the latch pressing portion 6 at the tip of the insertion portion 2 strikes one of the engagement pieces R21 of the latch R2 exposed within the groove R10, moving the engagement piece R21 toward the back of the entry groove R10, thereby rotating and displacing the latch R2 in the locking direction around the pivot R24 against the biasing force of the biasing means R25.

[0130] As the latch R2 rotates in the locking direction, the other engagement piece R22 descends from above the entry groove R10, and this other engagement piece R22 is positioned in the latch avoidance portion 4 provided in the middle of the insertion portion 2.

[0131] Specifically, as shown in Figure 5(b), in the fitting portion 2, the groove insertion shaft 60 at the tip of the groove insertion portion 200 pushes the one engagement piece portion R21 toward the back of the entry groove R10 in the entry direction while being inserted into the striker receiving groove R23, and the latch avoidance hole 40 midway through the groove insertion portion 200 receives the other engagement piece portion R22 that has descended into its interior.

[0132] When the insertion portion 2 is further inserted, as shown in Figure 4(b), the stopper portion 5 at the tip of the opening insertion portion 210 located at the opening D10 hits the inner edge portion D13 on the rear side, and the groove insertion shaft 60 at the tip of the groove insertion portion 200 is stopped and restricted just before the rearmost side, and the downward movement of the engaging piece portion R22 is restricted and stopped just before the locking claw R3.

[0133] That is, when the stopper portion 5 abuts against the rear inner edge portion D13, the advance position of the groove insertion shaft 60 in the entrance groove R10 is restricted to a position that holds the latch R2 in the unlocked state, as shown in FIG. 5(b).

[0134] When the fitting portion 2 is inserted into the opening D10 and the entrance groove R10, the upper and lower contact portions 3, 3' of the fitting portion 2 come into face-to-face contact with the upper and lower surfaces of the opening D10 and the entrance groove R10, respectively.

[0135] Furthermore, since the insertion portion 2 is formed with a width approximately equal to the width of the opening D10 (the width of the entry groove R10), one of the left and right side walls 2b, 2b' (in this embodiment, the left side wall 2b) functions as a lateral abutment surface that abuts against the inner edge of the short opening R101 of the opening D10 and the lateral side wall R12 of the entry groove R10, thereby increasing the contact area with the vehicle door D and the door lock member R as much as possible and improving supportability.

[0136] In this way, the fitting portion 2 tightly fits into the opening D10 and the entrance groove R10 at the upper and lower contact portions 3, 3', making it possible to integrally fix and support the door lock member R at a member mounting position inside the vehicle door D.

[0137] Furthermore, when the insertion portion 2 is inserted into the opening D10 and the entry groove R10, the positioning plate 7 provided on one side of the insertion portion 2 positions the multiple insertion holes 70 formed on the plate surface in the same phase as the multiple fastening holes D14 formed on the end face D1c of the vehicle door D, as shown in Figure 6(a), and is positioned in opposing contact with the end face D1c of the vehicle door D.

[0138] In this state, both hands of the worker are free, and the worker can stably perform the operation of fastening and attaching the door lock member R to the vehicle door D via the fastener B. That is, as shown in FIG. 6(b), the fastener B is positioned in a correct position with the axis of the fastener B aligned with the hole axes of the fastening holes D14, R13 by the insertion hole 70, and the fastener B is advanced to be fastened straight into the fastening holes D14, R13. Enter The fastening operation is performed.

[0139] Finally, door The lock member mounting jig A is removed from the entrance groove R10 of the door lock member R and the opening D10 of the vehicle door D along the extension direction of the vehicle door D, thereby completing the mounting work of the door lock member R to the vehicle door D.

[0140] That is, the removal operation of the jig A1 is performed by removing the insertion portion 2 along the width direction via the gripping portion 1 from the longitudinal opening D102 in the opening D10 of the end face D1c of the vehicle door D and the longitudinal opening R102 side of the entry groove R10 of the door lock member R to the outside.

[0141] Thus, the present invention door The lock member mounting jig A provides good support for the door lock member R at the mounting position on the inside of the vehicle door D, allowing for reliable mounting of the door lock member R to the vehicle door D via the fastener B.

[0142] [3. Second embodiment door Locking component mounting jig Next, regarding the second embodiment of the present invention, door The locking member mounting jig will be described with reference to the drawings. door 1 is a perspective view and a schematic cross-sectional side view showing the configuration of a locking member mounting jig according to a first embodiment of the present invention; door Portions having the same configuration as the locking member mounting jig A1 are given the same reference numerals and their explanations are omitted.

[0143] In this embodiment door The locking member attachment jig A2 is the same as that according to the first embodiment. door It has substantially the same configuration as the locking member attachment jig A1, but the configurations of the latch avoidance portion 4, stopper portion 5, and latch pressing portion 6 are different.

[0144] That is, the fitting portion 2 has a base-end stopper portion 50 formed on the base end side and abutting against one side surface D2 of the vehicle door D near the opening D10 to regulate the position of fitting into the fitting groove R10. In other words, the jig A2 has two stoppers, the base-end stopper portion 50 and a stopper portion 5 at the tip of the fitting portion 2, as shown in Figures 7(a) and 7(b).

[0145] As shown in Figure 7(b), the base-end stopper portion 50 only needs to be formed at the base end position of the insertion portion 2 so that it can regulate the insertion portion 2 at an entry position that achieves close contact with the opening D10 and entry groove R10 of the insertion portion 2, and in this embodiment it is formed by attaching a stopper plate 51 of a predetermined thickness to the lower base end of the insertion portion 2.

[0146] 7(a), the fitting portion 2 has a square cutout in the front half of one side wall (left side wall 2b) that faces the lateral side wall R12 of the entry groove R10, thereby forming a latch avoidance recess 41 as the latch avoidance portion 4. In other words, the fitting portion 2 has a generally one-sided convex shape in plan view by excluding the portion facing one side of the entry groove R10 in the front half of the groove insertion portion 200 and forming a step in the center in the extension direction, thereby forming the latch avoidance recess 41.

[0147] 7(a), the latch pressing portion 6 is configured with a grooved insertion shaft 61 that protrudes horizontally from the vicinity of the tip at the bottom of the notched latch avoidance recess 41. In other words, the grooved insertion shaft 61 is cantilevered at the tip of the fitting portion 2.

[0148] The jig A2 thus configured is the same as that of the first embodiment. door It is possible to obtain the same effects as the lock member attachment jig A1, and also to reduce material costs by simplifying the structure.

[0149] As described above, according to the present invention, a door lock member having an entrance groove for a striker corresponding to an opening of a vehicle door for the entrance of a striker is attached to the vehicle door via a fastener. Install Use when door Locking component removal Tsukeji a gripping portion; and a locking member extending from the gripping portion and connecting the opening of the vehicle door and the doorand an insertion portion to be inserted into the entrance groove of the locking member, the insertion portion having upper and lower abutment portions at its upper and lower surfaces that respectively abut against the upper and lower inner edge portions of the opening and the upper and lower groove edges of the entrance groove; a latch avoidance portion at its midpoint that passes through and avoids a latch that protrudes and displaces up and down within the entrance groove as the insertion portion enters the entrance groove; a stopper portion at its tip that abuts against the inner edge surface at the back side of the opening in the entrance direction to regulate the entry position into the entrance groove; and a latch pressing portion that is juxtaposed to the stopper portion in the width direction and that presses and pivotally displaces the latch in the entrance groove back side in the entrance direction while placing it in the striker receiving groove of the latch. This makes it possible to firmly and stably support the door lock member at a member attachment position on the inside of the vehicle door, and effectively assists the installation work of the door lock member to the vehicle door using a fastener, thereby improving workability.

[0150] In other words, the vehicle door and the door lock member are fixed integrally at the member mounting position, preventing misalignment, improving the supportability of the door lock member on the vehicle door and enabling the lock member to be firmly supported on the vehicle door at the same position.

[0151] In addition, the stopper portion formed at the tip restricts the position at which the insertion portion enters the insertion groove, making it easy to insert the insertion portion via the grip portion, thereby improving workability.

[0152] Furthermore, the latch pressing portion at the tip of the insertion portion pushes the latch in the entry groove all the way to the back and rotates it while placing it in the striker receiving groove of the latch, and the latch avoidance portion at the middle portion can be inserted to avoid the latch that is protruding and displacing into the entry groove, thereby achieving stable support without inadvertently reducing the contact area between the upper and lower abutment portions and the entry groove.

[0153] As a result, not only door lock members with a basic structure but also lock members with special structures can be fitted well into the opening and entry groove of the insertion portion, ensuring solid support of the door lock member on the vehicle door.

[0154] Furthermore, even when subjected to fastening stress accompanying the tightening operation of the fastener, the latch pressing portion is positioned in the striker receiving groove of the latch, so the door lock member does not rattle or shift from the member mounting position inside the vehicle door, and the door lock member can be stably fastened and fixed to the vehicle door.

[0155] In other words, by using this jig to hold the door lock member at the member installation position inside the vehicle door, it is possible to eliminate the need for the worker to support the member, thereby reducing labor and workload. Anyone can easily and stably perform the tightening operation to screw in and fasten the member, which has the effect of improving the robustness of the vehicle door after the door lock member has been installed.
