Description

[Background technology]

[0001] The present invention relates to a holder and a method for holding an opening / closing part of a vehicle during painting, and more particularly to a holder and a method for holding an opening / closing part such as a door when painting the body of a vehicle.

[0002] When applying electrocoating to a vehicle body, for example, the door, which is an opening and closing part, is sent into the electrocoating tank for electrocoating in a slightly open state rather than in a completely closed state. For this reason, a holder is required to hold and secure the door in a slightly open state. In the past, for example, a metal fitting was set on the door opening sill flange, and both ends of a round steel hanger were engaged with the left door and the right door, which were respectively in a slightly open state. This prevents the door from closing or opening due to external forces when the vehicle body enters or leaves the electrocoating tank.

[0003] Patent Document 1 also discloses a locking device for locking a vehicle door during painting. The locking device is composed of a hook for engaging with the door, a hook for engaging with the center pillar, and a connecting part for connecting the two hooks. The hook for engaging with the door is inserted and locked into a gap in the thickness direction of the door into which the window glass of the door is inserted. On the other hand, the hook for engaging with the center pillar is an engaging member having four engaging pieces that can engage with the center pillar, and has a flattened C-shape as a whole, and is fixed to the center pillar by a screw. And, since the two hooks are connected by a connecting part, the center pillar and the door are held in a slightly open state by the length of the connecting part. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 3-135475 Summary of the Invention [Problem to be solved by the invention]

[0005] The holders for holding and fixing the door in a slightly open position, including those in Patent Document 1, had to be designed and manufactured to suit each vehicle to be worked on. For example, in Patent Document 1, the hooks that engage with the center pillars had to be formed so that they could engage with the shape of the center pillars of the vehicle to be worked on. In other words, the holders up to now had to be prepared for each vehicle to be worked on, and were therefore not very versatile. In addition, the work of attaching the components of the holder to each location was complicated and time-consuming.

[0006] The present invention has been made in consideration of the above problems, and its object is to provide a holder and a holding method for an opening / closing part of a vehicle during painting that is highly versatile and can be attached to work objects of different types and shapes, and also allows for easy attachment work. [Means for solving the problem]

[0007] In order to achieve the above object, one embodiment of a holder for an opening / closing part during painting of a vehicle according to the present invention comprises: A vehicle having a body and an opening / closing part provided on the body in an openable / closable manner is painted. In the vehicle painting, a holder for an opening / closing part of the vehicle is held in an open state during painting of the vehicle, A main body portion formed of an elastic member and capable of stretching for a predetermined length; a first locking portion provided at one end of the main body portion and capable of being locked to the body main body side component; an arm portion provided at the other end of the main body portion and made of an elastic member that forms a predetermined angle with respect to the extension direction of the main body portion; and a second locking portion provided at a tip of the arm portion and capable of locking with the opening / closing portion when the first locking portion is in the locked state; a fulcrum portion formed between the first engaging portion and the second engaging portion of the main body portion and brought into contact with the body side component when the first engaging portion is in the engaged state; a third locking portion provided between the fulcrum portion of the main body portion and the second locking portion, the third locking portion being capable of being locked to the body side component when the first locking portion and the second locking portion are in the locked state and the fulcrum portion is in the abutting state, The angle that the arm portion makes with respect to the main body portion is set so that when the first locking portion, the second locking portion, and the third locking portion are each in the locked state and the fulcrum portion is in the abutting state, tension is applied to the main body portion and the arm portion due to twisting and bending.

[0008] With this configuration, the holder for the opening / closing part of a vehicle during painting according to the present invention is installed between the body component and the opening / closing part in the open state, thereby enabling stable holding of the opening / closing part during painting. To install this holder on a vehicle, for example, first, the first locking part at one end of the main body is locked to the body component, and in this state, the fulcrum part is abutted against the body component. Next, the third locking part located on the other end side of the fulcrum part is locked to the body component. Finally, the second locking part provided on the arm part at the other end of the main body is locked to the opening / closing part in the open state.

[0009] At this time, the second locking part is locked to the opening / closing part in a state where the main body part and the arm part are twisted and bent. As a result, tension is applied to the main body part due to the twisting and bending, and the movement of the opening / closing part is restricted by this tension. Therefore, even if an external force is applied to the opening / closing part during painting, the opening / closing part can be reliably maintained in an open state. Furthermore, the locking of the first locking part and the second locking part is literally a locking, and there is no need to perform installation or fixing work using other members. Therefore, as long as there is a place where it can be locked, it can be installed, and the installation is highly versatile for multiple vehicle models. Effect of the Invention

[0010] According to the holder and holding method for an opening / closing part during painting of a vehicle of the present invention, the opening / closing part of the vehicle can be held open during painting by attaching the holder through a simple locking operation. Furthermore, the maintenance of the held state is ensured by tension generated by twisting and bending of the main body and arm parts of the holder, so there is no need for complicated installation work. Furthermore, versatility in installation for different vehicle types is ensured. Therefore, the workability of holding the opening / closing part of the vehicle during painting is improved, and it is possible to improve the workability of painting.

[Diagram 5] 2 is an explanatory diagram of twisting and bending that occurs in the holder shown in FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of a holder for an opening / closing part during painting of a vehicle according to the present invention will be described in detail with reference to the drawings. In this embodiment, the body side component to which the first locking part is locked is shown as an example of a center pillar of the vehicle. Also, the opening / closing part is shown as an example of a front right door of the vehicle. Furthermore, the painting is shown as an example of electro-deposition painting.

[0013] FIG. 1 shows an overall perspective view of the retainer, and FIG. 2 shows a perspective view of the retainer when mounted on a vehicle. FIG. 3 shows a side view of the retainer when mounted on a vehicle, and FIG. 4 shows a front view of the retainer when mounted on a vehicle as viewed from the rear of the vehicle. The retainer 10 has a main body portion 12 made of an elastic material. One end portion 12a of the main body portion 12 is formed with a first locking portion 16-1 that is locked to a body side component in the vicinity of the opening / closing portion 26, in this embodiment, a center pillar 30. In this embodiment, the first locking portion 16-1 is provided at an angle with respect to the extension direction of the main body portion 12.

[0014] Also, an arm portion 14-1 made of an elastic member that forms a predetermined angle with respect to the extension direction of the main body portion 12 is formed on the other end portion 12b of the main body portion 12. A second locking portion 20-1 that can be locked to the opening / closing portion 26 when the arm portion 14-1 is in an locked state with the first locking portion 16-1 is formed on the tip of the arm portion 14-1. In this embodiment, the angle that the arm portion 14-1 makes with respect to the extension direction of the main body portion 12 is approximately 90°, and a predetermined angle is provided between the base end and tip end of the arm portion 14-1.

[0015] Between the first locking portion 16-1 and the second locking portion 20-1 of the main body portion 12, in the vicinity of the first locking portion 16-1 in this embodiment, there is formed a fulcrum portion 18-1 that is in contact with the center pillar 30 when the first locking portion 16-1 is in a locked state with the center pillar 30. In addition, between the fulcrum portion 18-1 and the second locking portion 20-1 of the main body portion 12, in the approximately middle position of the main body portion 12 in this embodiment, there is formed a third locking portion 22-1 that can be locked to the center pillar 30 when the first locking portion 16-1 and the second locking portion 20-1 are in a locked state and the fulcrum portion 18-1 is in a contact state with the center pillar 30.

[0016] The main body 12 is made of a rod-shaped elastic material, such as round steel, or other materials such as high-strength plastic resin. The arm 14-1 is also made of a rod-shaped elastic material, such as round steel.

[0017] In this embodiment, the first locking portion 16-1, the fulcrum portion 18-1, the third locking portion 22-1, the arm portion 14-1 and the second locking portion 20-1 are formed in pairs symmetrically with respect to the center line of the main body portion 12.

[0018] By forming them as a pair, it is possible to use a common retainer 10 for both the left and right opening / closing parts of a vehicle. In other words, there is no need to prepare separate retainers for the left opening / closing part and the right opening / closing part of a vehicle; this retainer 10 can be used for both.

[0019] The first locking portion 16 has a locking piece 16a-1 so as to be locked to a body side component located near the opening / closing portion 26, for example, an opening 30a of a center pillar 30. The locking piece 16a-1 is hooked onto the opening 30a formed in the center pillar 30, thereby locking the first locking portion 16 to the center pillar 30 (see FIGS. 2 and 3).

[0020] The fulcrum portion 18-1 is formed in the vicinity of the first locking portion 16-1 of the main body portion 12, and comes into contact with the center pillar 30 when the first locking portion 16-1 is in an locked state with the center pillar 30. In this embodiment, the fulcrum portion 18-1 is made of the same rod-shaped elastic member as the main body portion 12. This fulcrum portion 18-1 serves as a fulcrum for an external force acting on the retainer 10 when the first locking portion 16-1, the second locking portion 20-1, and the third locking portion 22-1 are in an locked state.

[0021] The third locking portion 22-1 is provided in the approximate center of the main body 12 and is locked to a flange portion 28 provided on the center pillar 30, thereby preventing the main body 12 from coming off the flange portion 28. In this embodiment, a flat plate 22a-1 having a notch 22b-1 formed therein is used for the third locking portion 22-1 in order to fit into the flange portion 28. Also, a round bar 22c-1 is attached to the flat plate 22a-1 to prevent damage caused by contact between the opening / closing portion 26 and the vehicle body.

[0022] A second locking portion 20-1 is formed at the tip of the arm portion 14-1. In this embodiment, the second locking portion 20-1 is configured as a claw portion 20a-1 that locks into an opening 26a formed in the opening / closing portion 26.

[0023] Next, a procedure for mounting the retainer 10 on a vehicle will be described. First, the first locking portion 16-1 is locked to the opening 30a formed in the center pillar 30. As described above, the locking portion 16a-1 of the first locking portion 16-1 is hooked onto the opening 30a formed in the center pillar 30, thereby locking the retainer 10 to the opening 30a.

[0024] Next, the fulcrum portion 18-1 is brought into contact with the center pillar 30. Then, the cutout portion 22b-1 of the third locking portion 22-1 is fitted into the flange portion 28 formed on the center pillar 30. When the second locking portion 20-1 is not locked to the opening / closing portion 26, almost no external force is applied to the first locking portion 16-1, the fulcrum portion 18-1, and the third locking portion 22-1.

[0025] In this state, the second locking portion 20-1 is located, for example, above the opening 26a of the opening / closing portion 26. The worker grips the second locking portion 20-1 and pushes it down below the opening, then releases his / her hand to hook the claw portion 20a-1 of the second locking portion 20-1 to the opening 26a. Alternatively, since the tip of the claw portion 20a-1 of the second locking portion 20-1 is inclined, by closing the opening / closing portion 26, the flange portion of the opening 26a pushes down the claw portion 20a-1 of the second locking portion 20-1, and the opening / closing portion 26 is hooked to the second locking portion 20-1. In a state in which the second locking portion 20-1 is locked to the opening / closing portion 26, tension is generated in the main body portion 12 and the arm portion 14 of the holder 10 due to twisting and bending.

[0026] FIG. 5 explains the twisting and bending that occurs in the main body 10 and the arm 14 when the retainer 10 is attached to the opening / closing section 26 of the vehicle. Consider the case where the second locking section 20-1 is pressed downward by a load A. The retainer 10 has a fulcrum section 18-1 in contact with the center pillar 30, and the main body 12 is first bent by this load A. When the main body 12 is bent to its elastic limit, the arm 14-1 is then bent downward. Then, a torque is generated in the main body 12 that is the product of the load A and the linear distance L from the claw section 20a-1 of the arm 14-1 to the other end 12b of the main body 12, and a twist B occurs in the main body 12 as shown in the figure. That is, a twisting and bending occurs in the main body 12. Furthermore, because of the above-mentioned bending and because the angle between the body 12 and the arm 14 is not strictly 90 degrees, the arm 14-1 also twists.

[0027] With the above-described configuration, the holder 10 for the opening / closing part of a vehicle during painting according to the present invention is installed across the center pillar 30 and the opening / closing part 26 in the open state, making it possible to stably hold the opening / closing part 26 during painting.

[0028] That is, the second locking portion 20-1 is locked to the opening / closing portion 26 in a state where the main body portion 12 and the arm portion 14-1 are twisted and bent. As a result, tension is applied to the main body portion 12 due to the twisting and bending, and the movement of the opening / closing portion 26 is restricted by this tension. Therefore, even if an external force is applied to the opening / closing portion 26 during painting, the opening / closing portion 26 can be reliably maintained in an open state. Furthermore, the locking between the first locking portion 16-1 and the second locking portion 20-1 is literally a locking, and no installation or fixing work using other members is required. Therefore, as long as there is a place where it can be locked, it can be attached, and the installation is highly versatile for multiple vehicle models.

[0029] In addition, in this embodiment, when the first locking portion 16-1, the second locking portion 20-1 and the third locking portion 22-1 are each in an engaged state and the fulcrum portion 18-1 is in an abutting state, the other end 12b of the main body portion 12 is located inside the vehicle, and the angle between the main body portion 12 and the arm portion 14 is set so that the base end of the arm portion 14-1 provided on the other end 12b of the main body portion 12 is located at the lowest position in the vertical direction of the vehicle, lower than the first locking portion 16-1, the fulcrum portion 18-1, the third locking portion 22-1 and the second locking portion 20-1.

[0030] With this configuration, the base end of the arm portion 14-1 is located at the lowest position, so that when painting is performed by electrodeposition, for example, it is possible to guide the electrodeposition liquid adhering to the main body portion 12 and the arm portion 14-1 to the base end side of the arm portion 14-1 located inside the vehicle. This prevents the electrodeposition liquid from dripping onto the exterior surface of the body, and protects the outer surface of the body.

[0031] Furthermore, a protrusion, which extends at an incline downward from the second engagement portion 20-1 and has a tip located on the inside side of the opening / closing portion 26 when the second engagement portion 20-1 is in the engaged state, is provided at the lower part of the second engagement portion 20-1; in this embodiment, this is a flat plate 24-1.

[0032] As a result, for example, during electrocoating, electrocoating liquid adhering to the second engaging portion 20-1 and its vicinity is guided by the flat plate 24-1 extending downward and drips inside the opening / closing portion 26. Therefore, electrocoating liquid on the second engaging portion 20-1 side is prevented from dripping onto the exterior surface of the body, and the outer surface of the body is protected.

[0033] Furthermore, the method of holding an opening / closing part of a vehicle during painting of the present invention is a method of holding an opening / closing part 26 during painting of a vehicle that has a body main body and an opening / closing part 26 that is openably and closably provided on the body main body, in which the opening / closing part 26 is held in an open position when painting the vehicle using the above-mentioned retaining device 10, characterized in that the first engagement portion 16-1 is engaged with the center pillar 30, and in the engagement state of the first engagement portion 16-1, the fulcrum portion 18-1 is abutted against the center pillar 30, and in this contact state, the third engagement portion 22-1 is engaged with the center pillar 30, and in the engagement state of the first engagement portion 16-1 and the third engagement portion 22-1 and the abutting state of the fulcrum portion 18-1, the second engagement portion 20-1 is engaged with the opening / closing part 26 so that tension is applied to the main body portion 12 and the arm portion 14 due to twisting and bending.

[0034] With this method, the first locking portion 16-1, the fulcrum portion 18-1, and the third locking portion 22-1 are locked and in contact with each other, and finally, the second locking portion 20-1 is locked to the opening / closing portion 26 under the above-mentioned tension, so that the opening / closing portion 26 can be easily held in the open state. That is, the opening / closing portion 26 is maintained in the open state during painting work only by the locking action of the locking portions. Also, since the main installation work is the locking action, high versatility in installation is ensured for vehicles of different shapes.

[0035] The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. For example, in the main body, the first locking portion 16-1 is provided at one end 12a of the main body 12 at an angle with respect to the extension direction of the main body 12, but depending on the vehicle model, the angle may not be provided. Also, the arm portion 14-1 is provided at an angle of approximately 90° with respect to the extension direction of the main body 12, but this is not restrictive. Furthermore, the third locking portion 22-1 has a notch portion 22b-1 that fits into the flange portion 28 of the center pillar 30, but is not limited to this configuration. [Explanation of symbols]
