Description

  The present invention relates to a clip suitable for fixing exterior parts such as a radiator grill of an automobile to a vehicle body and a part fixing structure using the clip.

  Clips are often used to attach automotive parts. In many cases, exterior parts such as a radiator grill are also fixed to the vehicle body using a clip. The clip for attaching the exterior parts has a structure considering waterproofness.

  For example, FIG. 7 is a cross-sectional view showing a structure for attaching a radiator grill, which is an exterior part of an automobile, to a vehicle body panel. As shown in FIG. 7, the back surface 101 a of the radiator grille 101 is provided with a plurality of locking portions 111 for locking the clip 130, and each locking portion 111 has a pin portion 131 a of the male member 131 of the clip 130. A hole portion 111a into which is inserted is formed. On the other hand, the body panel 102 is formed with a plurality of holes 102a into which the female members 132 of the clips 130 are fitted. The hole 111a of each locking part 111 and each hole 102a of the vehicle body panel 102 are arranged at positions corresponding to each other.

The clip 130 includes a male member 131 and a female member 132.
The male member 131 is formed with a predetermined clearance from the pin portion 131a, a first hook-like portion 131b formed at the base end of the pin portion 131a and press-contacted to one surface of the locking portion 111, and the first hook-like portion 131b. A second hook-shaped portion 131c that presses against the other surface of the locking portion 111 and a spherical protrusion 131d formed at the tip of the pin portion 131a are provided.

  The female member 132 has an outer shape formed in a tapered shape (spindle shape) that gradually decreases in diameter from the proximal end toward the distal end, and the tapered diameter that gradually decreases in diameter from the proximal end side opening. A hole 132a formed in a tapered shape, a spherical locking portion 132b having a reduced diameter formed at the bottom (tip) of the hole 132a, and an annular lip protruding from the outer periphery of the inlet of the hole 132a 132c and a constricted portion 132d formed on the outer periphery adjacent to the lip portion 132c.

The female member 132 is inserted into the hole 102a of the vehicle body panel 102 with the packing 134 fitted thereto, and is fixed to the vehicle body panel 102 in a state where the constricted part 132d reaches the edge of the hole 102a while being slightly elastically deformed. Is done. In this state, the female member 132 is not detached from the vehicle body panel 102 because it is fitted to the edge of the constricted portion 132d hole 102a. In this state, the surface on the vehicle body panel side of the annular lip portion 132c is pressed against the vehicle body panel 102 via the packing 134, and the packing 134 fills and seals the gap between the annular lip portion 132c and the vehicle body panel 102.
The male member 131 inserts the base portion of the pin portion 131a into the hole portion 111a of the locking portion 111 and sandwiches the periphery of the hole portion 111a of the locking portion 111 by the first hook-shaped portion 131b and the second hook-shaped portion 131c. In this state, it is locked to the locking portion 111.

  When the radiator grille 101 with the male member 131 mounted on each locking part 111 is aligned with the vehicle body panel 102 with the female member 132 mounted thereon, and the radiator grill 101 is pressed against the vehicle body panel 102, each locking part 111 The pin 131a of the male member 131 enters the corresponding hole 132a of the female member 132, and the spherical protrusion 131d at the tip of the pin 131a fits into the spherical locking portion 132b at the bottom of the hole 132a. Since the inner diameter of the entrance of the spherical locking portion 132b is smaller than the outer diameter of the spherical projection 131d, the spherical projection 131d is fitted while the diameter of the entrance of the spherical locking portion 132b is expanded by elastic deformation. Since the female member 132 is restored and the inner diameter of the entrance is reduced, the spherical protrusion 131d is locked in the spherical locking portion 132b.

  However, in the case of such a clip 130, when high-pressure water is injected into the gap between the radiator grille 101 and the vehicle body panel 102 as indicated by an arrow A1 during a car wash or the like, the annular lip that is in pressure contact with the vehicle body panel 102 The outer periphery of the portion 132c and the packing 134 may receive high-pressure water as indicated by an arrow A2, and a gap may be formed between the packing 134 and the vehicle body panel 102, so that water may enter the inside of the vehicle body panel 102.

Therefore, it is possible to change the shape of the vehicle body panel 102 to the shape shown by the two-dot chain line in FIG. 7 so that high-pressure water does not directly reach the outer peripheral portion of the annular lip portion 132c. In addition, it is necessary to further improve the shape accuracy of each part, and a solution by other means is desired.
In contrast, Patent Documents 1 to 3 describe a waterproof clip with an umbrella including an umbrella that covers an annular lip portion.

  FIG. 8 is a cross-sectional view showing the waterproof clip with an umbrella described in Patent Document 1 in its attached state. The same function as in FIG. Omitted. The umbrella-attached waterproof clip 230 is composed of a male member 231 and a female member 232, similarly to the clip 130 of FIG. 7. However, in this waterproof clip 230 with umbrella, instead of the spherical protrusion 131d and the spherical locking portion 132b of the clip 130, the male member 231 is provided with a conical enlarged diameter portion 231d, and the female member 232 is a tapered cylindrical type. A reduced diameter opening 232b having a reduced diameter is provided, and the conical enlarged diameter portion 231d protrudes from the reduced diameter opening 232b and is locked.

  The male member 231 is formed with an umbrella part 231e that covers the annular lip part 232c of the female member 232. When the waterproof clip 230 with umbrella is attached, the umbrella part 231e covers the annular lip part 232c of the female member 232, so Even if it is injected into the gap between the radiator grill 201 and the vehicle body panel 202, the outer peripheral portion of the annular lip portion 232c that is in pressure contact with the vehicle body panel 202 does not receive high-pressure water directly, and water enters the inside of the vehicle body panel 202. Can be prevented.

Registered Utility Model No. 2545466 Japanese Patent No. 4436266 JP 2011-89538 A

  By the way, when fixing parts (for example, exterior parts, such as a radiator grill) to the panel (for example, vehicle body) to be attached using the clip which consists of the above-mentioned male member and a female member, a male member and a female member are used. After mounting on the component and the mounting target panel in advance, the component is pressed against the mounting target to fit the male member to the female member.

  In order to achieve tight and sufficient rigidity between the male member and the female member, it is necessary to increase the shape accuracy and rigidity of the fitting portion between the male member and the female member. When the component is pressed against the mounting target and the male member is fitted to the female member, it is necessary to apply a large load. For this reason, normally, when the component is pressed against the panel to be attached, for example, as shown by an arrow F1 in FIG. 7, an impact force is applied to the component to fit the male member to the female member.

  However, when the impact force F1 is applied to the component in this manner, the impact force applied to the component is changed from the location (the locking portion 111 of the radiator grill 101) that supports the male member of the component to the seat surface (second) of the male member. Since it is applied to the flange portion 131c), a large load is partially applied to the seating surface of the male member, and this portion may be damaged. As the mounting accuracy of the components and the rigidity and strength of the mounting portion are secured, the impact force F1 supplied at the time of mounting increases, which is a big problem. Even the techniques of Patent Documents 1 to 3 cannot solve this problem.

  The present invention is intended to solve such a problem. When a part is attached to a panel member using a clip, the clip can be prevented from being damaged even if a large impact force is applied. It aims at providing the fixation structure of the used component.

  In order to achieve the above object, the clip of the present invention includes a pin portion having a diameter-expanded portion formed at the tip and a first locking portion locked in a first locking hole formed in the component. A female member having a male member, a hole, a reduced diameter portion formed at the back end of the hole, and a second locking portion locked in a second locking hole formed in the panel member And when the component having the male member locked thereon is fixed to the panel member having the female member locked, the enlarged diameter portion is fitted into the reduced diameter portion from the front side of the component. When an impact force is applied, an impact force transmission portion is provided that simultaneously contacts the back surface of the component and the surface of the panel member to transmit the impact force to the panel member.

The female member is formed with an annular seal portion that seals between the outer periphery of the female member and the periphery of the second locking hole, and the male member is formed with an umbrella portion that covers the seal portion. The impact force transmission part is preferably formed on the outer peripheral part of the umbrella part.
Moreover, it is preferable to provide a packing interposed between the annular seal portion and the periphery of the second locking hole.

  Further, the male member locking portion is provided on the back surface of the component and has a plate-like portion that is perpendicular to the axial direction when the pin portion is mounted and in which the first locking hole is formed. The panel member is formed with a female member locking portion in which the second locking hole is formed, and the impact force transmitting portion includes the male member locking portion and the female member locking portion. It is preferable to arrange | position between.

  Furthermore, the first locking portion is formed on the outer periphery of the base portion of the pin portion, and the first hook-shaped portion disposed on the surface side of the plate-shaped portion where the first locking hole is formed, and the plate A second hook-like portion disposed on the back side of the hook-like portion, and is locked in a state where the plate-like portion is sandwiched by the first and second hook-like portions, and the impact force transmitting portion is It is preferable that it is formed on the outer peripheral portion of the second bowl-shaped portion.

  The component fixing structure of the present invention is a fixing structure for fixing the component to the panel member using the clip according to any one of claims 1 to 5, wherein the component is fixed on the back surface of the component. The male member locking portion is formed from the rear surface of the component in the axial direction when the pin portion is mounted, and is formed at the tip of the vertical wall portion, and the axial direction A plate-like portion that faces in a direction perpendicular to the first hole and is formed with the first locking hole, and the impact force transmitting portion is interposed between the tip of the standing wall portion and the panel member. It is characterized by being.

  According to the clip of the present invention, when the component is fixed to the panel member, when an impact force for fitting the enlarged diameter portion into the reduced diameter portion is applied from the front side of the component, the impact force transmitting portion is connected to the back surface of the component. Simultaneously abutting on the surface of the panel member and transmitting the impact force to the panel member, the impact force applied to the clip is alleviated, damage to the clip is avoided, and durability is improved.

  If the female member is formed with an annular seal portion that seals between the outer periphery of the female member and the peripheral edge of the second locking hole, water can be prevented from entering from the front surface side to the back surface side of the panel member. If the umbrella part is formed on the male member so as to cover the seal part, the umbrella part protects the high pressure water from being directly sprayed to the seal part, and the high pressure water also from the front side to the back side of the panel member. Intrusion of water can be prevented. If an impact force transmission part is formed in the outer peripheral part of this umbrella part, the impact force applied to a clip can be relieved efficiently using the umbrella part.

  Sealing can be improved if a packing is interposed between the annular seal portion and the peripheral edge of the second locking hole. In this case, the packing is protected by the umbrella portion, and high-pressure water is directly injected into the packing. This eliminates the entry of water from the front surface side to the back surface side of the panel member even for high-pressure water.

  Further, a male member locking portion having a plate-like portion that is oriented in a direction perpendicular to the axial direction when the pin portion is mounted and has a first locking hole is provided on the rear surface of the component. If a female member locking part having a second locking hole is formed in the member and the impact force transmitting part is arranged between the male member locking part and the female member locking part, the clip The impact force applied to the clip can be reduced while being used without being exposed to the surface of the component.

  The first locking portion is formed on the outer periphery of the base portion of the pin portion, and is disposed on the front side of the plate-like portion where the first locking hole is formed, and on the back side of the plate-like portion. A second flange-like portion, and when the plate-like portion is held by the first and second flange-like portions, the impact force transmitting portion is formed on the outer peripheral portion of the second flange-like portion. Thus, the impact force applied to the clip can be efficiently reduced by using the second hook-shaped portion.

  Further, according to the component fixing structure of the present invention, the impact force transmitting portion is provided at the tip of the standing wall portion that is erected in the axial direction when the pin portion is mounted in the male member locking portion that projects from the back surface of the component. When the impact force for fitting the expanded diameter portion of the male member into the reduced diameter portion of the female member is applied from the front side of the component, the impact force is It is added to the pin part of the male member through the plate-like part, and the enlarged diameter part of the pin part is inserted into the reduced diameter part of the female member, but on the other hand, it is transmitted to the panel member through the standing wall part and the impact force transmitting part. The impact force applied to the clip is alleviated, the damage to the clip is avoided, and the durability is improved.

[First Embodiment]
First, the first embodiment will be described.
As shown in FIG. 1, a plurality of male member locking portions 11 that lock the clip 30 are provided on the rear surface 1 a of the radiator grill 1, and the male member 31 of the clip 30 is provided on each male member locking portion 11. A first engagement hole 11a into which the pin portion 31a is fitted is formed. On the other hand, the vehicle body panel 2 provided at the front portion of the vehicle body is provided with a plurality of female member locking portions 20 each having a second engagement hole 2a in which the female member 32 of the clip 30 is fitted. The first engagement holes 11a of the male member locking portions 11 and the second engagement holes 2a of the female member locking portions 20 are arranged at positions corresponding to each other.

As shown in FIGS. 1 to 3, the clip 30 includes a male member 31 and a female member 32, and a packing 34 is further used when the clip 30 is attached to the vehicle body.
The male member 31 includes a pin portion 31a formed in a tapered shape gradually reducing in diameter from the base end toward the tip, and a first portion formed at the base end of the pin portion 31a and locked to the male member locking portion 11. 33 A of latching | locking parts and the spherical protrusion (diameter expansion | extension part) 31d formed by expanding in the front-end | tip of the pin part 31a are provided. The first locking portion 33A includes a first hook-shaped portion 31b and a second hook-shaped portion 33.

  The female member 32 has an outer shape formed in a tapered shape (spindle shape) that gradually decreases in diameter from the proximal end to the distal end, and the tapered diameter that gradually decreases in diameter from the opening on the proximal end side. A hole portion (pin insertion hole portion) 32a formed in a tapered shape, a spherical locking portion (reduced diameter portion) 32b having a reduced diameter formed at the bottom portion (tip portion) of the hole portion 32a, and a hole portion 32a An annular lip portion (annular seal portion) 32c projecting from the outer periphery of the inlet of the second portion, and a second engagement formed on the entrance portion of the hole portion 32a adjacent to the lip portion 32c and engaged with the female member engagement portion 20. 32A. The second locking portion 32A is provided with a constricted portion 32d formed on the outer periphery adjacent to the lip portion 32c.

  The female member 32 is inserted into the second engagement hole 2a of the female member locking portion 20 of the vehicle body panel 2 with the packing 34 fitted thereto. At this time, the second locking portion 32A is constricted while being slightly elastically deformed. The portion 32d is fixed to the vehicle body panel 2 in a state where the portion 32d is fitted into the edge of the second engagement hole 2a. In this state, the constricted portion 32d is fitted to the edge of the second engagement hole 2a, and the female member 32 is unlikely to be detached from the vehicle body panel 2.

  The packing 34 is formed in a circular plate shape having a hole in the center (that is, a bowl shape) using an elastic material such as rubber. The inner diameter of the center hole of the packing 34 is set slightly larger than the base portion of the female member 32 provided with the annular lip portion 32c so that the female member 32 can be smoothly inserted. The outer shape of the packing 34 is set to be equal to or slightly larger than the outer diameter of the annular lip portion 32c, and the surface pressure between the annular lip portion 32c and the vehicle body panel 2 is reliably received to seal between the two. It has become.

  In particular, when the pin portion 31a of the male member 31 is subsequently inserted into the hole portion 32a, the base portion of the pin portion 31a is tightly adhered to the inner surface around the opening of the hole portion 32a inside the constricted portion 32d. Elastic deformation of the constricted portion 32d toward the shrinking side is prevented, the female member 32 is more difficult to be detached from the vehicle body panel 2, and rattling of the female member 32 to the vehicle body panel 2 is also prevented.

  In the state in which the female member 32 is fixed to the vehicle body panel 2 in this manner, the back surface (opposite surface to the vehicle body panel 2) of the outer peripheral portion of the annular lip portion 32c positioned on the front surface side (vehicle body front side) of the vehicle body panel 2 Is pressed against the vehicle body panel 2 with the packing 34 interposed therebetween, and the packing 34 fills and seals the gap between the female member 32 and the female member engaging portion 20 around the second engagement hole 2a of the vehicle body panel 2.

  On the other hand, in the male member 31, the base portion of the pin portion 31a is fitted into the first engagement hole 11a of the male member locking portion 11, and the first hook-shaped portion 31b and the second hook-shaped portion 33 are inserted into the first locking portion 33A. And the male member locking portion 11 is locked to the male member locking portion 11 with the peripheral edge of the first engagement hole 11a sandwiched therebetween.

  That is, the male member locking portion 11 includes a standing wall portion 12 erected from the back surface 1a of the radiator grille 1 in the axial direction of the male member 31 and the female member 32 (axial direction when the pin portion 31a is mounted), and the standing wall. And a plate-like portion 13 formed at the tip of the portion 12 and oriented in a direction perpendicular to the axial direction. The plate-like portion 13 has a first engagement hole 11a.

  As shown in FIG. 4, the plate-like portion 13 is formed in a rectangular shape, and the standing wall portion 12 has three edge portions excluding one edge portion (side edge portion) of the four edge portions of the plate-like portion 13. The first engagement hole 11a is provided to open at one edge of the plate-like portion 13 where the standing wall portion 12 is not provided. The male member 31 has the base portion of the pin portion 31 a inserted into the first engagement hole 11 a from the opening portion, and the first hook-shaped portion 31 b is formed on the front surface side of the plate-shaped portion 13, and the back surface side of the plate-shaped portion 13 is formed. It arrange | positions so that the 2nd hook-shaped part 33 may press-contact. Accordingly, the male member 31 is locked to the male member locking portion 11 in a state where the plate-like portion 13 is sandwiched between the first hook-like portion 31b and the second hook-like portion 33.

  When the radiator grille 1 in which the male member 31 is mounted on each male member locking portion 11 is aligned with the vehicle body panel 2 in which the female member 32 is mounted, and the radiator grille 1 is pressed against the vehicle body panel 2, each male member is The pin portion 31a of the male member 31 of the locking portion 11 enters the corresponding hole portion 32a of the female member 32, and the spherical protrusion portion 31d at the tip of the pin portion 31a enters the spherical locking portion 32b at the bottom of the hole portion 32a. The radiator grill 1 is fixed to the vehicle body panel 2.

  In this state, since the inner diameter of the entrance of the spherical locking portion 32b is smaller than the outer diameter of the spherical projection 31d, the spherical projection 31d is fitted while the diameter of the entrance of the spherical locking portion 32b is expanded by elastic deformation, After the insertion, the female member 32 is restored and the inlet inner diameter is reduced, so that the spherical protrusion 31d is locked in the spherical locking portion 32b and is prevented from coming off. The radiator grille 1 is securely fixed to the vehicle body panel 2 by fitting the spherical protrusions 31d into the spherical engaging portions 32b of the plurality of clips.

  By the way, when the radiator grille 1 is fixed to the vehicle body panel 2 by the clip 30, the second hook-shaped portion 33 of the clip 30 is engaged with the second engagement of the vehicle body panel 2 on the outer periphery of the annular lip portion 32 c of the female member 32. An umbrella portion 33b is formed to cover the seal portion between the periphery of the hole 2a.

  That is, as shown in FIG. 2, the second hook-shaped portion 33 protrudes from the disk-shaped hook-shaped main body 33a extending outward from the pin portion 31a and on the back side of the outer periphery of the hook-shaped main body 33a. The annular protrusion 33b functions as an umbrella part that contacts or approaches the surface of the vehicle body panel 2 when the radiator grille 1 is mounted and covers the seal part.

  Further, the outer periphery of the flange-shaped body 33a and the annular protrusion 33b are interposed between the front end (the end on the back side) of the standing wall 12 and the surface of the vehicle body panel 2 when the radiator grille 1 is mounted. A part of the impact force F1 applied when the grill 1 is fixed to the vehicle body panel 2 is directly transmitted to the vehicle body panel 2, and the impact force F1 applied to the clip 30, in particular, the first locking portion 33A of the male member 31 is reduced. It is configured as an impact force transmission portion 33c that relaxes input.

Since the clip and component fixing structure according to the first embodiment of the present invention is configured as described above, the following operations and effects can be obtained.
That is, when the radiator grille 1 is fixed to the vehicle body panel 2, the radiator 31 is fitted with the spherical protrusion 31 d of the pin 31 a of the male member 31 in the spherical locking portion 32 b of the hole 32 a of the female member 32. Although the impact force F1 is applied from the front side of the grill 1, if this impact force F1 is applied to the first locking portion 33A of the male member 31, the first locking portion 33A may be damaged. In this regard, when the impact force F1 is applied to the front side of the radiator grill 1, a part of the impact force F1 is directly transmitted to the vehicle body panel 2 through the standing wall portion 12 and the impact force transmission portion 33c, and therefore the first locking portion 33A. Thus, it is possible to avoid an excessive impact force and to eliminate the possibility of causing damage.

  Moreover, since the impact force transmission part 33c is provided using the 2nd hook-shaped part 33 of the 1st latching | locking part 33A which latches the male member 31 to the male member latching | locking part 11, it is material by simple structure. The impact force transmitting portion 33c can be provided efficiently and space-efficiently, and the impact force applied to the clip 30 can be reduced and the clip 30 can be protected while suppressing the cost.

  Further, the annular protrusion 33b constituting the impact force transmitting portion 33c of the second hook-shaped portion 33 contacts or approaches the surface of the vehicle body panel 2 when the radiator grille 1 is mounted, and the outer peripheral portion of the annular lip portion 32c is the vehicle body panel. 2 and functions as an umbrella portion that covers a seal portion that seals a gap between the female member 32 and the female member locking portion 20 around the second engagement hole 2a of the vehicle body panel 2.

  Therefore, as shown by arrows A1 and A2 in FIG. 1, even when high-pressure water is injected into the gap between the radiator grill 1 and the vehicle body panel 2, the outer periphery of the annular lip portion 32c and the packing 34 that are in pressure contact with the vehicle body panel 2 Since the portion is covered with the umbrella portion (annular protrusion) 33b, this portion does not receive high-pressure water directly, and water enters the inside of the vehicle body panel 2 from between the packing 34 and the vehicle body panel 2. Can be prevented.

  Also in this respect, since the umbrella part 33b is provided using the second hook-like part 33 of the first locking part 33A for locking the male member 31 to the male member locking part 11, the material can be made with a simple configuration. The impact force transmitting portion 33c can be provided efficiently and space-efficiently, and water can be prevented from entering the inside of the vehicle body panel 2 while suppressing costs.

  Further, according to the present fixed structure, the impact force transmitting portion 33c is arranged in the axial direction of the male member 31 and the female member 32 (attachment of the pin portion 31a) at the male member engaging portion 11 protruding from the back surface 1a of the radiator grill 1. Since it is interposed between the front end of the standing wall portion 12 erected in the axial direction) and the panel member 2, the impact force applied to the clip 30 can be surely reduced using the impact force transmission portion 33c. And damage to the clip 30 is avoided, and durability is improved.

  In addition, the structure of the reduced diameter portion of the female member 32 of the clip 30 is a spherical locking portion 32b whose inlet is reduced in diameter, and the spherical locking portion 32b is bag-shaped and has no opening other than the inlet, and the female member The hole 32a (pin insertion hole) 32a itself is also bag-shaped and has no opening other than the inlet, so that water leaks into the vehicle body panel 2 even if water enters the hole 32a of the female member 32. There is nothing to do.

[Second Embodiment]
Next, a second embodiment will be described.
In this embodiment, the clip 30 is the same as that of the first embodiment, but the shapes of components and panel members are different from those of the first embodiment.

  That is, as shown in FIG. 5, a plurality of male member locking portions 51 for locking the clip 30 are provided on the back surface 10 a of the component (for example, radiator grille) 10. A first engagement hole 51a into which the pin portion 31a of the male member 31 of the clip 30 is fitted is formed. On the other hand, the vehicle body panel 22 provided at the front of the vehicle body is provided with a plurality of female member locking portions 22A formed with second engagement holes 22a into which the female members 32 of the clips 30 are fitted.

A rectangular annular protrusion 43b protruding from the rear surface of the outer periphery of the outer peripheral surface of the vehicle body. The annular protrusion 43b functions as an umbrella portion that contacts or approaches the surface of the vehicle body panel 2 when the radiator grille 1 is mounted and covers the seal portion. The rectangular annular protrusion 43b is formed to correspond to the four edge portions of the plate-like portion 13 and the standing wall portion 12 arranged in a U-shape along the edge portion.

  The outer periphery of the flange-shaped body 43a and the rectangular annular protrusion 43b are interposed between the tip of the standing wall 12 (the end on the back side) and the surface of the vehicle body panel 2 when the radiator grille 1 is mounted. A part of the impact force F1 applied when the grille 1 is fixed to the vehicle body panel 2 is directly transmitted to the vehicle body panel 2, and the impact force F1 applied to the clip 40, in particular, the first locking portion 43A of the male member 41 is reduced. It is configured as an impact force transmission portion 43c that relaxes input.

  Therefore, in the case of the present embodiment, the impact force transmitting portion 43c contacts all the ends of the standing wall portion 12, and the impact force applied to the clip 30 can be transmitted to the vehicle body panel 2, and the clip 30 is prevented from being damaged. The effect of improving durability can be obtained more reliably.
