  According to the door edge protection device of Patent Document 1, depending on the structure of the passenger car on which the device is mounted, there are other members (for example, a part of the rear door panel, a part of the pillar, etc.) on the rotation track of the protector. There is a possibility that the protector and other members interfere with each other.

  In this specification, the door edge protection apparatus which can suppress generation | occurrence | production of the situation where a protector interferes with another member is provided.

  In this specification, the door edge protection apparatus which protects the edge part which is the edge part by the side of the open end of the outer panel of the door of a passenger car is disclosed. The door edge protection device is a slide mechanism that slides the protector and the protector between a protection position and a storage position along a creeping direction of the open end surface of the door, and when the door is opened, And a slide mechanism that places the protector in the protected position and places the protector in the storage position when the door is closed. When the protector is in the protected position, the protector protrudes outside the edge portion, and when in the stowed position, the protector is inside the edge portion and is surrounded by the inner surface of the edge portion and the open end surface. And a base portion formed integrally with the protection portion and slidably attached to the slide mechanism.

  According to this configuration, the protector is disposed in the storage position when the door is closed, and is disposed in the protection position when the door is opened. When the protector is disposed at the protection position, the edge portion is protected by the protection portion protruding outside the edge portion. Then, the slide mechanism slides the protector between the protection position and the storage position along the creeping direction of the open end surface of the door. Therefore, for example, when a conventional door edge protection device having a structure in which a protector is rotated and protrudes to a protected position is mounted on a passenger car, the rotating protector and other members (for example, a part of a rear door panel and a part of a pillar) Etc.), the protection position and the storage position can be obtained without interfering the protector with other members by mounting the door edge protection device instead of the conventional device. May be able to slide between the two. Therefore, according to said door edge protection apparatus, generation | occurrence | production of the situation where a protector interferes with another member can be suppressed.

  The slide mechanism further moves the protector away from the open end surface along the normal direction of the open end surface while the protector slides between the protected position and the storage position. You may make it move in the direction which approaches the said open end surface after making it.

  According to this configuration, even when the door edge protection device is mounted on a passenger car having a door whose edge portion protrudes to the open end side from the open end surface of the door, for example, the protector is placed in the protected position. During the sliding movement with respect to the storage position, the protector of the protector can be operated in a trajectory that bypasses the edge portion with the sliding movement. Therefore, according to this configuration, when the protector slides between the storage position and the protection position, occurrence of a situation where the protector interferes with the edge portion can be appropriately suppressed.

  When the door is opened, the slide mechanism does not move the protector from the storage position while the door opening is smaller than the specific opening, and the door opening is the specific opening. When the door is closed, when the door is closed, the protector is moved to the protection position while the door is open above the specific opening. When the door is moved from the position to the storage position and the opening of the door is smaller than the specific opening, the protector does not have to be moved from the storage position.

  According to this configuration, when the door is opened, the protector does not move from the storage position while the door opening is smaller than the specific opening, and the door opening exceeds the specific opening. Since the protector is moved from the storage position to the protection position, there are other members of the passenger car (for example, part of the rear door panel, part of the pillar, etc.) in the vicinity of the protector disposed at the storage position. Even if it exists, generation | occurrence | production of the situation which a protector and another member interfere is suppressed. Similarly, when the door is closed, the protector is moved from the protection position to the storage position while the door opening is equal to or greater than the specific opening (that is, until the door is closed to the specific opening) If the opening of the door is smaller than the specific opening, the protector is not moved from the storage position, so that the situation where the protector interferes with other members is suppressed. According to this configuration, even when the other member of the passenger car exists in the vicinity of the protector disposed at the storage position, it is possible to appropriately suppress the occurrence of a situation where the protector and the other member interfere with each other.

  The slide mechanism is a top member that is attached to the base portion of the protector and includes a guide groove, and the guide groove has a first portion having a first end and a direction different from the first portion. And a second portion having a second end portion, the top member having a second end portion, and pivotable about a fulcrum portion, and the action point portion is guided in the guide groove. A guide pin is provided, and the force point portion receives a force from the door receiving member by hitting the door receiving member of the passenger car when the door is closed, and the force lever portion is directed toward the door receiving member. And an urging member that urges the lens. The top member does not move the protector from the stowed position while the guide pin is present in the first part, and is not within the second part while the guide pin is present in the second part. The protector may be moved between the storage position and the protection position in accordance with the movement of the guide pin. (A) When the door is closed, the force point portion receives a force from the door receiving member, the guide pin exists at the first end portion in the first portion, and (b) the When the door is opened, the force received by the force point portion from the door receiving member decreases, and accordingly, the guide pin is moved to the first end while the door opening is smaller than the specific opening. When the opening degree of the door is equal to or greater than the specific opening degree, the guide pin moves in the second part toward the second end. (C) When the door is fully opened, the force point portion and the door receiving member are separated from each other, the force point portion does not receive force from the door receiving member, and the guide pin is Present at the second end in the second part, (d) the door is closed In this case, the force applied to the power receiving portion from the door receiving member is increased by the force applied to the door receiving member, and accordingly, the opening of the door is equal to or greater than the specific opening. When the guide pin moves in the second portion from the second end toward the first portion and the opening of the door is smaller than the specific opening, the guide pin is moved to the first portion. What is necessary is just to move inside toward the said 1st end part.

  According to this configuration, the occurrence of a situation in which the protector and the other member interfere with each other even when the other member of the passenger car exists in the vicinity of the protector disposed at the storage position is appropriately suppressed by a relatively simple configuration. be able to.

  The sliding mechanism is fixed at a predetermined position with a drive rod that receives a force from the door receiving member when the end of the sliding mechanism comes into contact with the door receiving member of the passenger car when the door is closed. A holding member that is held so as to be insertable, and an annular member that is provided between the end portion and the holding member of the drive rod and is displaceable along a longitudinal direction of the drive rod; the holding member; A first compression spring provided between the annular members and biasing the annular member in the direction of the door receiving member, the first compression spring having a drive rod inserted therein; and the annular member; A second compression spring provided between the end portions and biasing the end portion in the direction of the door receiving member, wherein a drive rod is inserted therein, and the biasing force is applied to the first compression spring; From the force A large transmission mechanism for changing the position of the protector according to the position of the second compression spring and the annular member, wherein the first compression spring is compressed and the annular member is disposed at the first position. The protector is moved to the retracted position, and the protector is moved to the protected position when the first compression spring is not compressed and the annular member is disposed at the second position, And a transmission mechanism. (A) When the door is closed, the end receives a force from the door receiving member, the first compression spring and the second compression spring are both compressed, and the annular member is When the door is opened (B) when the door is opened, the force that the end receives from the door receiving member decreases, and accordingly, the opening of the door is smaller than the specific opening. The second compression spring is restored to an uncompressed state, while the first compression spring is still compressed, the annular member is maintained in the first position, and the opening degree of the door is determined When the opening is equal to or greater than the opening, both the second compression spring and the first compression spring are restored to the uncompressed state, the annular member is disposed at the second position, and (C) the door is fully opened. If it is, the end and the door receiver The material is separated, the end is not subjected to force from the door receiving member, the second compression spring and the first compression spring are not compressed, and the annular member is maintained in the second position, (D) When the door is closed, the force that the end receives from the door receiving member increases when the end hits the door receiving member. While the opening is equal to or greater than the opening, the first compression spring is compressed first, the second compression spring is not compressed, the annular member is disposed at the first position, and the opening of the door is the specific opening. When the opening is smaller than the opening, both the first compression spring and the second compression spring are compressed, and the annular member may be maintained in the first position.

  Even with this configuration, even when other members of the passenger car are present in the vicinity of the protector disposed at the storage position, the occurrence of a situation where the protector and the other member interfere with each other is appropriately suppressed by a relatively simple configuration. be able to.

  The protector and the slide mechanism may be formed separately from the door. The slide mechanism may be provided detachably with respect to the open end surface.

  According to this configuration, the door edge protection device can be detachably attached to the open end surface of the door. By attaching the door edge protection device described above, it is possible to protect an edge portion of a passenger car door on which the protection device is not installed in advance.

  The door edge protection device may further include a fixing member fixed to the open end surface. The fixing member detachably holds the slide mechanism and releases the hold of the slide mechanism when a load of a specific value or more is applied to at least one of the held protector and the slide mechanism. May be.

  According to this configuration, for example, when a part of the user's body or clothing is caught on at least one of the protector and the slide mechanism and a load exceeding a specific value is applied, the slide mechanism is removed from the fixed member. It is. Therefore, it is possible to prevent the slide mechanism and the protector from being damaged, and to prevent a part of the user's body, clothes, and the like from being damaged.

  The guide plates 44 and 46 are provided in parallel in the X-axis direction at a predetermined interval (that is, an interval slightly wider than the width of the protector 20 and the top portion 80). The guide plates 44 and 46 are provided with guide grooves 50 and 52 and guide rails 54 and 56. The guide grooves 50 and 52 are grooves formed in a substantially V shape. The guide rails 54 and 56 are rail members for guiding the top portion 80. The rotating shaft 58 is a shaft member for inserting the hole of the torsion spring 60 and the shaft hole 78 of the drive lever 70.

  The torsion spring 60 is a spring for biasing the drive lever 70 in a direction in which the drive lever 70 is rotated clockwise about the shaft hole 78 (clockwise in FIG. 2). One end of the torsion spring 60 is fixed to the mounting plate 40, and the other end is fixed to the drive lever 70.

  The drive lever 70 is a rod-like member whose both ends in the longitudinal direction are rounded and chamfered. The drive lever 70 includes a force point side end portion 72, an action point side end portion 74, a guide pin 76, and a shaft hole 78. As shown in FIG. 2, the power point side end portion 72 is an end portion disposed on the vehicle inner side. The power point side end portion 72 is an end portion on the side in contact with a door receiving member (refer to 510 in FIG. 4) of the passenger car. The action point side end portion 74 is an end portion on the side connected to the top portion 80. The guide pin 76 is formed at the action point side end portion 74. The guide pin 76 is disposed in the guide groove 90 of the top part 80. The guide pin 76 can move in the guide groove 90 along the guide groove 90. The rotating shaft 58 is inserted into the shaft hole 78. As a result, the drive lever 70 can rotate about the shaft hole 78 (with the shaft hole 78 as a fulcrum). As described above, the end of the torsion spring 60 is fixed to the drive lever 70. Thereby, the power point side end portion 72 of the drive lever 70 is urged toward the door receiving member of the passenger car.

  The top portion 80 is a member for holding the base portion 24 of the protector 20 and sliding the protector 20 along the guide rails 54 and 56. The top portion 80 includes guide recesses 82 and 84, a pin hole 86, and a guide groove 90.

  The guide groove 90 is a groove formed in a substantially L shape along the XY plane. The guide groove 90 has a first portion 92 formed along the Y-axis direction and a second portion formed along the X-axis direction. As described above, the guide pin 76 of the drive lever 70 is disposed in the guide groove 90.

  The fixing member 100 is a plate-like member that is formed in substantially the same area as the mounting plate 40. The back surface side of the fixing member 100 is fixed to the open end surface 506 of the door 500 (see FIG. 2). As shown in FIG. 3, a holding projection 102 for holding the back surface of the mounting plate 40 is formed on the front surface side of the fixing member 100. The holding protrusion 102 is a protrusion that can be fitted into a recess (not shown) formed on the back surface of the mounting plate 40. In the example of FIG. 3, only one holding protrusion 102 is shown, but actually, it is also formed at another position. By fitting the holding projections 102 into the recesses on the back surface of the mounting plate 40, the mounting plate 40 (that is, the slide mechanism 30) is held on the surface of the fixing member 100. However, when a load greater than a specific value is applied to the protector 20 and the slide mechanism 30 (for example, the drive lever 70) in the Z-axis direction, the holding projection 102 is detached from the recess on the back surface of the mounting plate 40. That is, in that case, the fixing member 100 releases the holding of the slide mechanism 30.

  As shown in FIG. 1, the cover member 110 is a member for covering the slide mechanism 30 and the protector 20. The cover member 110 is provided detachably with respect to the slide mechanism 30. 2 to 4 show a state in which the cover member 110 is removed for easy understanding of the structure. Even when the cover member 110 is attached to the slide mechanism 30, the operation of the protector 20 is not hindered. By providing the cover member 110, the slide mechanism 30 and the protector 20 are protected, and at the time of use, a part of the slide mechanism 30 and the protector 20 may reduce the possibility of damaging the user's body, clothes, and the like. it can.

  In order to form the door edge protection device 10 shown in FIG. 2 by combining the components shown in FIG. First, the mounting pin 28 of the protector 20 is fitted into the pin hole 86 of the top part 80. The rotation shaft 58 is provided with a torsion spring 60, and the rotation shaft 58 is inserted into the shaft hole 78 of the drive lever 70.

Then, the guide concave portions 82 and 84 of the top portion 80 and the guide rails 54 and 56 of the guide plates 44 and 46 are fitted, and the guide pin 76 of the drive lever 70 is inserted into the guide groove 90. Then, the guide pin 26 of the protector 20 is inserted into the guide grooves 50 and 52 of the guide plates 44 and 46. Then, a recess (not shown) on the back surface of the mounting plate 40 is fitted into the holding protrusion 102 of the fixing member 100. Thereby, the door edge protection apparatus 10 with the cover member 110 removed as shown in FIG. 2 is completed. When the cover member 110 is further attached, the door edge protection device 10 shown in FIG. 1 is completed.

(Operation of door edge protection device 10)
Then, with reference to FIG. 4, operation | movement of the door edge protection apparatus 10 of a present Example is demonstrated. In FIG. 4, illustration of some components is omitted for easy understanding. FIG. 4 shows a state in which the door 500 is closed in (a), and shows a state in which the door 500 is gradually opened in the order of (b), (c), and (d).

(When door 500 is opened)
When the door 500 is closed, as shown in FIG. 4A, the force point side end portion 72 of the drive lever 70 is in contact with the door receiving member 510, and the force point side end portion 72 includes the door. A force from the receiving member 510 is applied. As a result, the guide pin 76 provided at the action point side end 74 of the drive lever 70 is disposed at the end 92 a (see FIG. 3) in the first portion 92 of the guide groove 90. Along with this, the top part 80 is arranged at a position closest to the vehicle interior side. In this case, the protector 20 is disposed at the storage position. Specifically, the protector 20 is disposed inside the edge portion 504 of the outer panel 502 of the door 500 and in a space surrounded by the inner surface of the edge portion 504 and the open end surface 506. At this time, the guide pin 26 of the protector 20 is disposed at the end closest to the vehicle interior of the guide grooves 50 and 52 of the guide plates 44 and 46. Further, as shown in the figure, when the door 500 is closed, the edge portion 504 and a part of the rear door 520 of the passenger car are close to each other, and partly overlaps in the direction from the inside to the outside of the car. ing. In this state, the rear door 520 is close to the protection part 22 of the protector 20.

  When the door 500 is opened, as shown in FIG. 4B, the force that the force point side end 72 of the drive lever 70 receives from the door receiving member 510 decreases. However, at this time, the opening degree of the door 500 is smaller than the specific opening degree. As the door 500 is opened, the guide pin 76 provided at the action point side end 74 of the drive lever 70 moves in the first portion 92 of the guide groove 90 toward the second portion 94. However, while the guide pin 76 is present in the first portion 92, the top portion 80 does not move to the outside of the vehicle, but is maintained in a state of being disposed at a position closest to the inside of the vehicle. Therefore, as long as the opening degree of the door 500 is smaller than a specific opening degree, the protector 20 is maintained in the state arrange | positioned in the accommodation position. Even at this time, the rear door 520 is still in proximity to the protection part 22 of the protector 20. However, since the protector 20 has not moved from the storage position, the protector 20 and the rear door 520 do not interfere with each other.

  When the door 500 is further opened and the opening degree of the door 500 reaches a specific opening degree or more, as shown in FIG. 4C, the force received by the force point side end portion 72 of the drive lever 70 from the door receiving member 510 is increased. Further decrease. Along with this, the guide pin 76 provided at the action point side end portion 74 of the drive lever 70 faces the end portion 94a (see FIG. 3) of the second portion 94 in the second portion 94 of the guide groove 90. Move. As the guide pin 76 moves in the second portion 94, the top portion 80 is pushed toward the outside of the vehicle. Then, the top portion 80 starts to slide along the guide rails 54 and 56 toward the outside of the vehicle. Along with this, the protector 20 attached to the top part 80 is also pushed by the top part 80 and starts sliding to the outside of the vehicle. That is, the protector 20 slides toward the vehicle exterior along the creeping direction of the open end surface 506 (along the Y-axis direction in FIG. 2). At this time, the guide pin 26 of the protector 20 moves along the guide grooves 50 and 52. As described above, the guide grooves 50 and 52 are formed in an inverted V shape bent in a direction away from the open end surface 506 along the normal line direction of the open end surface 506. Therefore, when the protector 20 slides, the protection part 22 of the protector 20 moves in a direction away from the open end surface 506. At this time, since the opening degree of the door 500 is already equal to or greater than the specific opening degree, the protector 20 that has moved in the direction away from the open end surface 506 does not interfere with the rear door 520.

  When the door 500 is further opened, as shown in FIG. 4D, the force that the force point side end portion 72 of the drive lever 70 receives from the door receiving member 510 further decreases. Accordingly, the guide pin 76 provided at the action point side end 74 of the drive lever 70 is disposed at the end 94 a of the second portion 94 of the guide groove 90. Accordingly, the top portion 80 is slid along the guide rails 54 and 56, and is disposed at the outermost position of the vehicle. And the protector 20 attached to the top part 80 also slides with the top part 80, and is arrange | positioned in the protection position which is the position outside the vehicle. The protector 20 is returned in a direction approaching the open end surface 506 by being guided along the inverted V-shaped guide grooves 50 and 52. As a result, the protection part 22 of the protector 20 arranged at the protection position protrudes outside the edge part 504 and covers and protects the outside and end face of the edge part 504.

  Although not shown, when the door 500 is further opened (that is, completely opened), the force point side end portion 72 is separated from the door receiving member 510, and the force from the door receiving member 510 is not applied to the force point side end portion 72. . In this case, the protector 20 is maintained in the above-described protected position (see (d) of FIG. 4).

(When door 500 is closed)
When the door 500 is closed from the opened state, the reverse operation to the case of opening the door 500 is performed. That is, when the door 500 is closed, as shown in FIG. 4D, the force point side end portion 72 comes into contact with the door receiving member 510 and the force from the door receiving member 510 starts to be applied to the force point side end portion 72. .

  Further, while the door 500 is closed and the opening degree of the door 500 is equal to or larger than the specific opening degree, the guide pin 76 is disposed in the second portion 94 of the guide groove 90 in the first portion as shown in FIG. By moving toward the portion 92, the top portion 80 is slid toward the vehicle inner side, and accordingly, the protector 20 is also slid toward the vehicle inner side. That is, the protector 20 slides toward the vehicle interior along the creeping direction of the open end surface 506 (along the Y-axis direction in FIG. 2). At this time, the protector 22 of the protector 20 is temporarily separated from the open end surface 506 along the guide grooves 50 and 52 and then moves in a direction approaching the open end surface 506. As a result, while the opening degree of the door 500 is greater than or equal to the specific opening degree (that is, before closing to the specific opening degree), the protector 20 is moved from the protection position (position (d) in FIG. 4) to the storage position. (Position (b) in FIG. 4). Even when the door 500 is closed, the protector 20 is returned to the storage position without interfering with the rear door 520.

  Further, when the door 500 is closed and the opening degree of the door 500 becomes smaller than a specific opening degree, the guide pin 76 moves into the end portion 92a in the first portion 92 of the guide groove 90 as shown in FIG. Move towards. However, the position of the frame portion 80 does not change while the guide pin 76 moves in the first portion 92. Therefore, the protector 20 is maintained in the storage position. As described above, the protector 20 is disposed at the storage position before the opening degree of the door 500 is closed to a specific opening degree. Therefore, even when the door 500 and the rear door 520 are close to each other, the protector 20 does not interfere with the rear door 520.

  When the door 500 is further closed, the door 500 is completely closed as shown in FIG.

  The configuration and operation of the door edge protection device 10 according to the present embodiment have been described above. As described above, in the door edge protection device 10 according to the present embodiment, the protector 20 is disposed at the storage position (see FIG. 4A) when the door 500 is closed, and the protection position when the door 500 is opened. (See (d) of FIG. 4). When the protector 20 is disposed at the protection position, the protection portion 22 protrudes outside the edge portion 504 and covers the edge portion 504, whereby the edge portion 504 is protected. The slide mechanism 30 slides the protector 20 along the creeping direction of the open end surface 506 of the door 500 (along the Y-axis direction in FIG. 2) between the protection position and the storage position. Therefore, for example, when a conventional door edge protection device having a structure in which a protector is rotated and protrudes to a protected position is mounted on a passenger car, the rotating protector and other members (for example, a part of a rear door panel and a part of a pillar) Etc.), the protector 20 can be protected without interfering with other members by mounting the door edge protection device 10 of this embodiment instead of the above-described conventional device. It can be slid between the position and the storage position. Therefore, according to the door edge protection device 10 of the present embodiment, it is possible to suppress the occurrence of a situation where the protector 20 interferes with other members (such as the rear door 520) as compared with the conventional device.

  In the present embodiment, when the protector 20 slides between the protection position and the storage position, the protector 22 is guided along the guide grooves 50 and 52 of the guide plates 44 and 46, so that the protection unit 22 is moved. Then, it can be operated in a trajectory that bypasses the edge portion 504 as the slide moves (see FIG. 4). Therefore, even when the door edge protection device 10 is mounted on a passenger car having a door in which the edge portion 504 protrudes closer to the open end side than the open end surface 506 as in this embodiment, the protector 20 The occurrence of a situation in which the protector 20 interferes with the edge portion 504 during the slide movement can be appropriately suppressed.

  Further, in the present embodiment, as shown in FIG. 4, when the door 500 is opened, the protector 20 does not move from the storage position while the opening degree of the door 500 is smaller than the specific opening degree ( 4 (see FIGS. 4A and 4B), the protector 20 moves from the storage position to the protection position after the opening degree of the door 500 exceeds a specific opening degree (see FIGS. 4C and 4D). Therefore, even when other members such as a part of the rear door 520 are present in the vicinity of the protector 20 arranged at the storage position, occurrence of a situation where the protector 20 and the other member interfere with each other is suppressed. Similarly, when the door 500 is closed, the protector 20 is moved from the protection position to the storage position while the opening degree of the door 500 is equal to or greater than the specific opening degree, and the opening degree of the door 500 is the specific opening degree. If it becomes smaller, since the protector 20 is not moved from the storage position, the occurrence of a situation where the protector 20 and other members interfere with each other is suppressed. According to the present embodiment, even when other members of the passenger car are present in the vicinity of the protector 20 disposed at the storage position, it is possible to appropriately suppress the occurrence of a situation where the protector 20 and the other members interfere with each other. it can.

  Further, the door edge protection device 10 of the present embodiment has a relatively simple mechanical configuration as shown in FIGS. Therefore, the door edge protection device 10 of the present embodiment can suppress interference between the protector 20 and other members with a relatively simple configuration.

  Further, the door edge protection device 10 of the present embodiment is formed separately from the passenger car door 500, and is attached to the open end surface 506 of the passenger car door 500 in a detachable manner (see FIG. 1). Therefore, by attaching the door edge protection device 10 of the present embodiment, it is possible to protect the edge portion of a passenger car door on which a predetermined protection device is not installed in advance.

  Further, in the door edge protection device 10 of this embodiment, the holding projections 102 of the fixing member 100 fixed to the open end surface 506 are fitted into the recesses on the back surface of the mounting plate 40, so that the mounting plate 40 (that is, the slide mechanism 30). ) Is held on the surface of the fixing member 100 (see FIG. 3). However, when a load of a specific value or more is applied to the protector 20 and the slide mechanism 30 (for example, the drive lever 70), the holding projection 102 is detached from the recess on the back surface of the mounting plate 40. That is, in that case, the fixing member 100 releases the holding of the slide mechanism 30. Therefore, for example, when a part of the user's body, clothes, or the like is caught on at least one of the protector 20 and the slide mechanism 30 and a load greater than a specific value is applied, the slide mechanism 30 is removed from the fixing member 100. . Therefore, it is possible to prevent the slide mechanism 30 and the protector 20 from being damaged, and it is possible to prevent a part of the user's body, clothes, and the like from being damaged.

  Further, the door edge protection device 10 of the present embodiment includes a cover member 110 for covering the slide mechanism 30 and the protector 20. Even when the cover member 110 is attached to the slide mechanism 30, the operation of the protector 20 is not hindered. By providing the cover member 110, the slide mechanism 30 and the protector 20 are protected, and at the time of use, a part of the slide mechanism 30 and the protector 20 may reduce the possibility of damaging the user's body, clothes, and the like. it can.

(Second embodiment)
With reference to FIGS. 5-7, the door edge protection apparatus 210 of a present Example is demonstrated. Similarly to the door edge protection device 10 of the first embodiment, the door edge protection device 210 of the present embodiment shown in FIG. 5 is also attached to the open end surface 506 of the passenger car door 500 in a detachable manner.

  As shown in FIGS. 5 and 6, the door edge protection device 210 according to the present embodiment also includes a protector 220, a slide mechanism 230, and a fixing member 300. 5 to 7, the cover member is not shown for easy understanding of the structure, but the door edge protection device 210 of this embodiment also includes a cover member for covering the slide mechanism 230. ing.

  The protector 220 includes a protection part 222, a base part 224, and a mounting pin 228. The protection part 222 is a part on one end side in the longitudinal direction of the protector 20 (Y-axis direction in the figure), and is a part that covers the edge part 504 when the protector 20 protrudes outside the door 500. The base 224 is a portion on the other end side in the longitudinal direction of the protector 20. The base 224 is formed integrally with the protection part 222. In the present embodiment, the base portion 224 is formed in a convex shape that curves toward the open end surface 506 side of the door 500 (the open end surface 506 side in the Z-axis direction in the figure). The mounting pin 228 is rotatably fitted in a pin hole 261a (described later) of the top portion 261.

  The slide mechanism 230 includes a mounting plate 240, a transmission mechanism 260, and an urging mechanism 270.

  The mounting plate 240 is a plate that extends along the creeping direction of the open end surface 506 of the door 500 (along the XY plane of FIG. 5). The mounting plate 40 is provided with guide rails 244 and 246 extending in the Z-axis direction of FIG. 3 (that is, the normal direction of the open end surface 506 of the door 500), a protrusion 250, and a shaft 266. . The guide rails 244 and 246 are provided in parallel with each other at a predetermined interval. The guide rails 244 and 246 are members that guide the sliding movement of the top portion 261 (described later). The protrusion 250 is a guide member for causing the protector 220 to move back toward the open end surface 506 after being lifted away from the open end surface 506 when the protector 220 slides. The shaft 266 is a member for rotatably supporting a second link portion 264 (described later).

  The transmission mechanism 260 is a mechanism for transmitting the force of the urging mechanism 270 to the protector 220. In this embodiment, the transmission mechanism 260 is a link-type mechanism, and includes a top part 261, a first link part 262, and a second link part 264. The top portion 261 is a member for holding the base portion 224 of the protector 220 and slidingly moving the protector 220 along the guide rails 244 and 246. The top part 261 has a pin hole 261 a for fitting the attachment pin 228 of the protector 220. One end of the first link part 262 is rotatably connected to the frame part 261 and the other end is rotatably connected to the second link part 264. The second link portion 264 is rotatably supported by the shaft 266, one end is rotatably connected to the first link portion 262, and the other end is rotatably connected to an annular member 276 (described later). The

  The biasing mechanism 270 includes a drive rod 271, an end 272, a holding member 274, an annular member 276, a first compression spring 280, and a second compression spring 290. The drive rod 271 is a rod disposed along the Y-axis direction. The end portion 272 is attached to the rear end portion of the drive rod 271 (that is, the end portion inside the vehicle). The end 272 contacts the door receiving member 510 (see FIG. 7) of the passenger car and receives a force from the door receiving member 510. The holding member 274 is fixed on the mounting plate 240 and holds the drive rod 271 so that it can be inserted. The annular member 276 is provided between the end 272 and the holding member 274 of the drive rod 271, and can be displaced along the longitudinal direction of the drive rod. The annular member 276 is rotatably connected to the end of the second link portion 264.

  The first compression spring 280 is a compression spring that is provided between the holding member 274 and the annular member 276 and biases the annular member 276 in the direction of the door receiving member 510 (see FIG. 7). A drive rod 271 is inserted into the first compression spring 280. The biasing force of the first compression spring 280 is smaller than the biasing force of the second compression spring 290.

  The second compression spring 290 is a compression spring that is provided between the annular member 276 and the end portion 272 and biases the end portion 272 toward the door receiving member 510. The drive rod 271 is also inserted into the second compression spring 290. The biasing force of the second compression spring 290 is larger than the biasing force of the first compression spring 280.

  The fixing member 300 is a plate-like member that is formed in substantially the same area as the mounting plate 240. The fixing member 300 has substantially the same configuration as the fixing member 100 of the first embodiment. That is, the back surface side of the fixing member 300 is fixed to the open end surface 506 of the door 500. A holding projection 302 for holding the back surface of the mounting plate 240 is formed on the front surface side of the fixing member 300.

  In order to form the door edge protection device 210 shown in FIG. 5 by combining the components shown in FIG. First, the mounting pin 228 of the protector 220 is inserted into the pin hole 261 a of the top part 261. Then, both side portions of the top portion 261 are fitted to the guide rails 244 and 246. Further, the top part 261, the first link part 262, the second link part 264, and the annular member 276 are connected. The second link portion 264 is supported on the shaft 266. The drive rod 271 is inserted into the holding member 274, the first compression spring 280, the annular member 276, and the second compression spring 290, and the end 272 is fixed to the rear end of the drive rod 271. Then, a recess (not shown) on the back surface of the mounting plate 240 is fitted into the holding protrusion 302 of the fixing member 300. As a result, the door edge protection device 210 with the cover member (not shown) removed as shown in FIG. 5 is completed.

(Operation of door edge protection device 210)
Next, the operation of the door edge protection device 210 of this embodiment will be described with reference to FIG. Also in FIG. 7, illustration of some components is omitted for easy understanding. FIG. 7 shows a state in which the door 500 is closed in (a), and shows a state in which the door 500 is opened in the order of (b), (c), and (d).

(When door 500 is opened)
When the door 500 is closed, as shown in FIG. 7A, the end portion 272 of the biasing mechanism 270 is in contact with the door receiving member 510, and the end portion 272 has the door receiving member 510. The power from is added. As a result, the first compression spring 280 and the second compression spring 290 are both compressed, and the annular member 276 is disposed at a position closest to the vehicle interior. In this case, the transmission mechanism 260 arranges the top part 261 at the position closest to the vehicle interior side. Accordingly, the protector 220 is disposed at the storage position.

  When the door 500 is opened, the force received by the end 272 from the door receiving member 510 decreases as shown in FIG. However, at this time, the opening degree of the door 500 is smaller than the specific opening degree. At this time, the second compression spring 290 having a large urging force (compression force) is restored (extended) before the first compression spring 280 having a small urging force. At this time, the position of the annular member 276 is substantially the same as the position (see FIG. 7A) while the door is closed. Therefore, the protector 220 is maintained in the storage position.

  When the door 500 is further opened and the opening degree of the door 500 reaches a specific opening degree or more, the force received by the end portion 272 from the door receiving member 510 is further reduced as shown in FIG. Along with this, the first compression spring 280 that has been compressed so far also starts to be restored to an uncompressed state. At this time, the annular member 276 starts moving toward the inside of the vehicle. Along with this, the top part 261 starts to slide outward along the guide rails 244 and 246. At this time, the convex portion of the base 224 of the protector 220 rides on the protrusion 250. Thereby, when the protector 220 slides, the protection part 222 of the protector 220 moves in a direction once away from the open end surface 506. At this time, since the opening degree of the door 500 is already equal to or greater than the specific opening degree, the protector 220 that has moved in the direction away from the open end surface 506 does not interfere with the rear door 520.

  When the door 500 is further opened, the force received by the end 272 from the door receiving member 510 is further reduced as shown in FIG. Accordingly, the first compression spring 280 is completely restored. Then, the top part 261 is slid along the guide rails 244 and 246, and is disposed at the outermost position of the vehicle. The protector 220 attached to the top part 261 also slides together with the top part 261 and is disposed at the protection position that is the position on the outermost side of the vehicle. At this time, since the convex portion of the base 224 of the protector 220 gets over the protrusion 250, the protector 222 of the protector 220 returns in a direction approaching the open end surface 506. As a result, the protection part 222 of the protector 220 arranged at the protection position protrudes outside the edge part 504 and covers and protects the outside and end face of the edge part 504.

  Although not shown, when the door 500 is further opened (that is, completely opened), the end 272 is separated from the door receiving member 510, and the force from the door receiving member 510 is not applied to the end 272. In this case, the protector 220 is maintained in the above-described protected position (see (d) of FIG. 7).

(When door 500 is closed)
When the door 500 is closed from the opened state, the reverse operation to the case of opening the door 500 is performed. That is, when the door 500 is closed, as shown in FIG. 7D, the end 272 comes into contact with the door receiving member 510, and a force from the door receiving member 510 starts to be applied to the end 272.

  Further, while the door 500 is closed and the opening degree of the door 500 is not less than a specific opening degree, as shown in FIG. 7C, the first compression spring 280 having a small urging force (compression force) is attached. The compression starts before the second compression spring 290 having a large force. Thereby, the movement of the annular member 276 to the outside of the vehicle is started, and accordingly, the sliding movement of the top part 261 to the inside of the vehicle is started. Thereby, the protector 220 also starts to slide toward the inside of the vehicle. At this time, the convex portion of the base 224 of the protector 220 rides on the protrusion 250, and the protector 222 of the protector 220 moves in a direction away from the open end surface 506. As a result, while the opening degree of the door 500 is equal to or larger than the specific opening degree (that is, before closing to the specific opening degree), the protector 220 is moved from the protection position (position (d) in FIG. 7) to the storage position. (Position (b) in FIG. 7). Even when the door 500 is closed, the protector 220 is returned to the storage position without interfering with the rear door 520.

  When the door 500 is further closed and the opening degree of the door 500 becomes smaller than the specific opening degree, the first compression spring 280 having a small urging force (compression force) is completely compressed as shown in FIG. The second compression spring 290 having a large biasing force also starts to be compressed. Accordingly, the annular member 276 is moved to the position on the outermost side of the vehicle, and accordingly, the top part 261 is also slid to the position on the innermost side of the vehicle. Thereby, the protector 220 is arrange | positioned in an accommodation position. As described above, the protector 220 is disposed at the storage position before the opening degree of the door 500 is closed to a specific opening degree. Therefore, even when the door 500 and the rear door 520 are close to each other, the protector 220 does not interfere with the rear door 520.

  When the door 500 is further closed, the door 500 is completely closed as shown in FIG. In this case, the second compression spring 290 is also completely compressed. Then, the protector 220 is maintained in the storage position.

  The configuration and operation of the door edge protection device 210 according to this embodiment have been described above. The door edge protection device 210 of this embodiment can also exhibit the same effects as the door edge protection device 10 of the first embodiment.

  Further, in this embodiment, when the protector 220 slides between the protection position and the storage position, the protruding portion of the base 224 moves over the protrusion 250, so that the protection portion 222 is moved to slide. Accordingly, it is possible to operate in a trajectory that bypasses the edge portion 504 (see FIG. 7). Therefore, also in the present embodiment, it is possible to appropriately suppress the occurrence of a situation in which the protector 220 interferes with the edge portion 504 when the protector 220 slides.

(Third embodiment)
With reference to FIGS. 8-10, the door edge protection apparatus 410 of a present Example is demonstrated. The door edge protection device 410 of this embodiment is a modification of the door edge protection device 210 of the second embodiment. The basic configuration of the door edge protection device 410 of this embodiment is the same as that of the door edge protection device 210 of the second embodiment, but is different from the second embodiment in that the transmission mechanism 460 is a gear system. 8 to 10, parts having the same configuration as the door edge protection device 210 of the second embodiment are shown using the same reference numerals as in FIGS. 5 to 7, and detailed description thereof is omitted.

  As shown in FIGS. 8 and 9, the door edge protection device 410 according to the present embodiment also includes a protector 220, a slide mechanism 230, and a fixing member 300. 8 to 10, illustration of the cover member is omitted for easy understanding of the structure.

  The protector 220 and the fixing member 300 of this embodiment are common to the second embodiment. The slide mechanism 230 according to the present embodiment also includes a mounting plate 240, a transmission mechanism 460, and an urging mechanism 270.

  The mounting plate 240 has guide rails 244 and 246 and a protrusion 250 as in the second embodiment. In the present embodiment, the mounting plate 240 further has a shaft 465. The shaft 465 is a rotation shaft of a pinion 464 described later.

  The transmission mechanism 460 is a gear type mechanism as described above. The transmission mechanism 460 includes a top part 461 and a pinion 464. The top portion 461 is a member that holds the base portion 224 of the protector 220 and slides the protector 220 along the guide rails 244 and 246. The top part 461 has a pin hole 461a for fitting the attachment pin 228 of the protector 220. A first rack 462 that engages with the pinion 464 is formed on the rear end side of the top portion 461. The pinion 464 is rotatably attached to the shaft 465 and is engaged with a first rack 462 of the top portion 461 and a second rack 277 (described later) of the annular member 276.

  The biasing mechanism 270 includes a drive rod 271, an end 272, a holding member 274, an annular member 276, a first compression spring 280, and a second compression spring 290. The biasing mechanism 270 of the present embodiment has the same configuration as the biasing mechanism 270 of the second embodiment, except that the annular member 276 has a second rack 277 that engages with the pinion 464 described above.

(Operation of Door Edge Protection Device 410)
Next, the operation of the door edge protection device 410 of this embodiment will be described with reference to FIG. FIG. 10 also shows a state in which the door 500 is closed in (a), and shows a state in which the door 500 is opened in the order of (b), (c), and (d).

(When door 500 is opened)
When the door 500 is closed, as shown in FIG. 10A, the end portion 272 of the urging mechanism 270 is in contact with the door receiving member 510, and the end portion 272 has the door receiving member 510. The power from is added. As a result, the first compression spring 280 and the second compression spring 290 are both compressed, and the annular member 276 is disposed at a position closest to the vehicle interior. In this case, the top part 461 is disposed at a position closest to the vehicle interior side. The protector 220 is disposed at the storage position.

  When the door 500 is opened, the force that the end 272 receives from the door receiving member 510 decreases as shown in FIG. However, at this time, the opening degree of the door 500 is smaller than the specific opening degree. At this time, the second compression spring 290 having a large urging force (compression force) is restored (extended) before the first compression spring 280 having a small urging force. At this time, the position of the annular member 276 is substantially the same as the position while the door is closed (see FIG. 10A). Therefore, the protector 220 is maintained in the storage position.

  When the door 500 is further opened and the opening degree of the door 500 reaches a specific opening degree or more, the force received by the end portion 272 from the door receiving member 510 is further reduced as shown in FIG. Along with this, the first compression spring 280 that has been compressed so far also starts to be restored to an uncompressed state. At this time, the annular member 276 and the second rack 277 start moving toward the vehicle interior side. Along with this, the top part 461 starts to slide outward along the guide rails 244 and 246. At this time, the convex portion of the base 224 of the protector 220 rides on the protrusion 250. Thereby, when the protector 220 slides, the protection part 222 of the protector 220 moves in a direction away from the open end surface 506. At this time, since the opening degree of the door 500 is already equal to or greater than the specific opening degree, the protector 220 that has moved in the direction away from the open end surface 506 does not interfere with the rear door 520.

  When the door 500 is further opened, the force received by the end portion 272 from the door receiving member 510 is further reduced as shown in FIG. Accordingly, the first compression spring 280 is completely restored. Accordingly, the annular member 276 and the second rack 277 are disposed at the innermost position. Then, the top portion 461 is slid along the guide rails 244 and 246, and is disposed at the outermost position. The protector 220 attached to the top part 461 also slides together with the top part 461 and is disposed at the protection position that is the position on the outermost side of the vehicle. At this time, since the convex portion of the base 224 of the protector 220 gets over the protrusion 250, the protector of the protector 220 approaches the open end surface 506. As a result, the protection part 222 of the protector 220 arranged at the protection position protrudes outside the edge part 504 and covers and protects the outside and end face of the edge part 504.

  Although not shown, when the door 500 is further opened (that is, completely opened), the end 272 is separated from the door receiving member 510, and the force from the door receiving member 510 is not applied to the end 272. In this case, the protector 220 is maintained at the above-described protected position (see (d) of FIG. 10).

(When door 500 is closed)
When the door 500 is closed from the opened state, the reverse operation to the case of opening the door 500 is performed. That is, when the door 500 is closed, as shown in FIG. 10D, the end portion 272 comes into contact with the door receiving member 510, and a force from the door receiving member 510 starts to be applied to the end portion 272.

  Further, while the door 500 is closed and the opening degree of the door 500 is not less than the specific opening degree, as shown in FIG. 10C, the first compression spring 280 having a small urging force (compression force) is attached. The compression starts before the second compression spring 290 having a large force. Thereby, the movement of the annular member 276 and the second rack 277 to the outside of the vehicle is started, and accordingly, the sliding movement of the top portion 461 to the inside of the vehicle is started. Thereby, the protector 220 also starts to slide toward the inside of the vehicle. At this time, the convex portion of the base 224 of the protector 220 rides on the protrusion 250, and the protector 222 of the protector 220 moves in a direction away from the open end surface 506. As a result, while the opening degree of the door 500 is equal to or larger than the specific opening degree (that is, before closing to the specific opening degree), the protector 220 is moved from the protection position (position (d) in FIG. 10) to the storage position. (Position (b) in FIG. 10). Even when the door 500 is closed, the protector 220 is returned to the storage position without interfering with the rear door 520.

  When the door 500 is further closed and the opening degree of the door 500 becomes smaller than the specific opening degree, the first compression spring 280 having a small urging force (compression force) is completely compressed as shown in FIG. The second compression spring 290 having a large biasing force also starts to be compressed.

  The configuration and operation of the door edge protection device 410 according to the present embodiment have been described above. The door edge protection device 410 of this embodiment can also exhibit the same effects as the door edge protection devices 10 and 210 of the first and second embodiments.

  As mentioned above, although the Example of the technique disclosed by this specification was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, the following modifications may be included.

(Modification 1) In each of the above embodiments, the door edge protection devices 10, 210, and 410 are all formed separately from the passenger car door 500 and attached to the open end surface 506 in a removable manner (see FIG. 1). However, the present invention is not limited thereto, and the door edge protection device may have a structure built in the door 500 in advance. That is, the elements corresponding to the protectors 20 and 220 and the slide mechanisms 30 and 230 in each of the above embodiments may be built in the door 500 in advance.

(Modification 2) In each of the above-described embodiments, when the protectors 20 and 220 slide between the protection position and the storage position, the protection parts 22 and 222 are bypassed, and the edge part 504 is bypassed as the slide moves. (See FIGS. 4, 7, and 10). However, the present invention is not limited to this, and when the protector is slid between the protection position and the storage position, the protector may be slid linearly without being operated in a trajectory that bypasses the edge portion 504.

(Modification 3) In each of the above embodiments, when the door 500 is opened, the protectors 20 and 220 are not moved from the storage position and the door 500 is opened while the opening of the door 500 is smaller than the specific opening. When the degree exceeds a specific opening, the protectors 20 and 220 are moved from the storage position to the protection position (see FIGS. 4, 7, and 10). Similarly, when the door 500 is closed, the protectors 20 and 220 are moved from the protection position to the storage position while the opening degree of the door 500 is greater than or equal to the specific opening degree. When it becomes smaller, the protectors 20 and 220 are not moved from the storage position. However, the protector may be moved from the storage position toward the protection position immediately after the door 500 is opened. Even when the door 500 is closed, as long as the protector is placed in the storage position before the door 500 is closed, the timing at which the protector moves may be arbitrary.

(Modification 4) In each of the above-described embodiments, when a load greater than a specific value is applied to the protectors 20, 220 or the slide mechanisms 30, 230, the slide mechanisms 30, 230 are removed from the fixing members 100, 300. However, the fixing members 100 and 300 may be omitted. In that case, the slide mechanisms 30 and 230 may be directly attached to the open end surface 506.

(Modification 5) In each of the embodiments described above, the door edge protection devices 10, 210, and 410 include the cover member 110, but the present invention is not limited thereto, and the cover member 110 may be omitted.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
