Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automobile door outside handle device.
[0002]
[Prior art]
As a so-called grip-type door outside handle device in which one end in the longitudinal direction of the handle body is pivotally supported by a handle case, for example, a device described in JP-A-10-266642 is known. In this conventional example, the handle body is provided with an operating leg that protrudes into the door body at the opposite end to the shaft support side end to the handle case, and when the handle body is rotated, an operation lever mounted on the back surface of the handle case is Operate and activate the door lock device inside the door body. An urging force is applied to the operation lever in a predetermined direction, and the handle body is urged toward an initial posture side stored in a predetermined position of the handle case.
[0003]
The handle case is provided with a leg insertion hole for penetrating the operation leg into the door body, and a sliding member for smooth operation of the handle body is attached to the peripheral wall of the leg insertion hole.
[0004]
[Problems to be solved by the invention]
By the way, generally in a grip type handle device, the span from the support shaft of the handle body to the operation leg is long, and a small amount of rattling on the support shaft becomes a large play on the operation leg. It is easy to cause rattling noise. In particular, as in the conventional example described above, when the handle body is indirectly maintained in the initial posture by the biasing force to the operation lever, rattling in the rotation direction is prevented by the biasing force to the operation lever. It is difficult to regulate the movement in the shake direction (rotation direction in a plane orthogonal to the rotation operation surface). By increasing the biasing force to the operating lever, it is possible to give the handle body a biasing force that does not easily move. However, applying an excessive biasing force increases the operating force of the handle body and improves operability. Make it worse.
[0005]
In order to solve such a problem, it is possible to prevent the steering wheel body from swinging by making the interval between the opposing sides of the sliding member in the conventional example substantially coincide with the dimensions of the operating leg. There are the following problems. In other words, the specifications of the handle body or handle case vary widely, such as whether the shape is the same, with or without surface treatment, or with a different surface treatment film. Depending on the surface treatment specifications, there is a difference between the operating leg and the leg insertion hole. The gap size also changes.
[0006]
In particular, when multiple types of surface treatment specifications are set on the handle case side, the sliding member can be used as an anti-rattle member even if the operating leg on the handle body side does not change in dimensions due to the specification change. Since the reference mounting surface of the sliding member varies depending on the surface treatment specifications, at least two types of sliding members are indispensable. On the other hand, since the variation in the gap is generally on the order of about 0.1 mm, it is difficult to distinguish the sliding member at first glance, and it is easy to assemble wrong parts, etc. Become.
[0007]
The present invention has been made in order to eliminate the above-mentioned drawbacks, and it is possible to reduce the number of parts and to facilitate manufacturing management of an automobile door outside handle device, and a handle case usable for the handle device. For the purpose of provision.
[0008]
[Means for Solving the Problems]
According to the present invention, the object is
Long-side direction end car door outside handle device with inserted manipulation legs 3 provided on the other end of the handle body 2 which is rotatably supported by the handle case 1 from the leg insertion hole 4 of the handle casing 1 inside the door body Because
The handle case 1 and the handle body 2 are subjected to the presence or absence of plating treatment or coating treatment on the inner wall surface of the leg insertion hole 4 or the outer surface of the operation leg 3, or the difference in plating film thickness or coating film thickness, or plating treatment. A highly surface-active resin material used for the handle case 1 and the handle body 2 for performing the coating process and the weather resistance used for the handle case 1 and the handle body 2 when the plating process and the coating process are not performed. Combining a pair selected from a plurality of types with different gap dimensions between the leg insertion hole 4 and the operating leg 3 due to the difference in shrinkage after molding with the resin material,
For the peripheral wall of the leg insertion hole 4 of the handle case 1, the one subjected to the plating treatment or the coating treatment is selected, or the one having the largest plating film thickness or coating film thickness is selected, or the shrinkage after molding When a combination of the handle case 1 and the handle main body 2 that minimizes the gap size is selected by selecting a resin material having a higher rate, the swing direction of the handle main body 2 can be reduced by contacting the operating leg 3. A protrusion 5 capable of preventing rattling and a holding portion 7 to which a bush 6 can be attached ;
Those not subjected to the plating treatment or coating treatment are selected, or those other than those having the thickest plating film thickness or coating film thickness are selected, or those using the resin material having a smaller shrinkage after molding When the handle case 1 and the handle body 2 are combined so that the gap dimension is not minimized by selecting the button, the bush 6 attached to the holding portion 7 is brought into contact with the operating leg 3 to change the swing direction of the handle body 2. This is accomplished by providing an automobile door outside handle device that prevents rattling.
[0009]
The handle device is configured by combining a pair selected from a plurality of types of handle cases 1 and handle bodies 2 having different surface treatment specifications. Due to the difference in surface treatment specifications, the dimensions of the leg insertion hole 4 or the operation leg 3 change, and the protrusion 5 is located between the leg insertion hole 4 and the operation leg 3 in the combination of the handle case 1 and the handle body 2. The projecting dimension is set so as to be able to come into contact with the operation leg 3 when the gap is minimum.
[0010]
Therefore, in the present invention, for example, when manufacturing two types of handle devices with or without surface treatment, when the surface treatment is not performed on the handle case 1 and the handle body 2, the operation leg 3 and the leg insertion hole 4 Since the gap between the two is maximized, the bush 6 necessary to fill the gap is mounted. On the other hand, when both are subjected to surface treatment, the gap is reduced by a dimension corresponding to the coating film or the plating film thickness, and the gap is minimized. Since the height of the protrusion 5 is set to a height that contacts the handle body 2 in this state, when the handle device of the specification is manufactured, it is not necessary to simply attach the bush 6, as in the conventional case. In addition, it is not necessary to attach another bush 6. As a result, the number of parts is reduced, and assembly of erroneous parts is prevented.
[0011]
In this case, if the bush 6 is mounted so as to sandwich the protrusion 5, the bush 6 is not easily detached.
[0012]
In addition, in the above-described outside handle device,

The leg insertion hole 4 is provided with a holding portion 7 to which a bush 6 that contacts the operation leg 3 and prevents shaking of the handle main body 2 can be mounted .
The inner wall of the leg insertion hole 4 is subjected to the above-described plating treatment or coating treatment, or the resin material having the largest plating film thickness or coating film thickness or having a larger shrinkage rate after molding is used. The protrusion dimension into the leg insertion hole 4 when the insertion hole 4 is the smallest is not subjected to the plating treatment or coating treatment, or the plating film thickness or coating film thickness is the smallest, or after molding When the bushing 6 is mounted on the holding portion 7 when the resin material having a smaller shrinkage rate is used, a protruding portion 5 is provided so as to match the protruding dimension of the bush 6 into the leg insertion hole 4 .
The leg insertion hole 4 of the protrusion 5 is formed by applying the plating treatment or the coating treatment, or by using the resin material having the largest plating film thickness or coating film thickness or having a larger shrinkage after molding. When the inward projecting dimension is maximized, the outside door handle device for an automobile that can prevent shaking of the handle body 2 by the protrusion 5 without attaching the bush 6 to the holding portion 7. The handle case 1 can be used.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 2 and 3, the outside handle device is a so-called grip-type handle device in which one end in the longitudinal direction of the handle body 2 is rotatably connected to the handle case 1, and the handle body 2 is operated to the rotating end side. A leg 3 is provided. The operating leg 3 enters the door body through the leg insertion hole 4 provided in the handle case 1. An operation lever 8 is rotatably supported on the back surface of the handle case 1 and is rotated in synchronization with the operation of the operation leg 3. The operation lever 8 is urged in a predetermined rotational direction by a torsion spring 9, and the handle body 2 is urged by the operation lever 8 and held in the initial rotation posture accommodated in the handle case 1 as shown in FIG. Is done.
[0014]
As shown by the arrow in FIG. 2B, when the handle body 2 is rotated around the support shaft 2a by grasping the handle body 2 from the initial rotation posture and pulling it out from the handle case 1, the operating leg 3 is moved outwardly of the vehicle body. The operation lever 8 is rotated. The operation lever 8 is connected to a door lock device (not shown) inside the door body via a rod (not shown), and the lock of the door lock device is released together with the rotation operation.
[0015]
The handle case 1 and the handle main body 2 are injection-molded products of synthetic resin material. The handle case 1 and the handle main body 2 are set in several kinds of surface treatment states, and a handle device is configured by appropriately combining them. .
[0016]
When the handle body 2 is in the initial rotation posture, the swing direction (in this specification, the direction indicated by the arrow A in FIG. 2A, that is, the rotation direction in the plane orthogonal to the rotation operation surface of the handle body 2) In order to prevent rattling in the vibration direction), as shown in FIG. 1, a protrusion 5 is provided on the inner wall of the leg insertion hole 4 so as to face the bush 6 and a bush 6 is attached. . As shown in FIG. 3, the protrusion 5 is formed as a long protrusion in the moving direction of the operation leg 3, and can also prevent rattling of the handle body 2 during operation.
[0017]
The bush 6 is made of a synthetic resin material having excellent self-lubricating properties, and is formed by hanging down a main body abutting piece 6b branched from both ends of the fixed piece 6a as shown in FIG. 4 (a). The bush 6 press-fits one main body abutting piece 6b into a holding part 7 formed adjacent to the projecting part 5, and sandwiches the projecting part 5 by a fitting groove 6c formed between the main body abutting pieces 6b. Attached so that it does not fall off easily. In order to increase the holding force of the bush 6, it is necessary that the bush 6 has a sufficient thickness to exhibit an appropriate rigidity, and the holding portion 7 has a sufficient depth so that the bush 6 can be accommodated. It is formed with.
[0018]
Further, in order to further increase the holding force of the bush 6, as shown in FIG. 4B, it is desirable to provide a press-fitting hole 6d in the fixed piece 6a and press-fit into the boss 1a on the handle case 1 side. Further, as shown in FIG. 5, when a sliding rib 6 e that is long in the moving direction of the operation leg 3 protrudes from each main body contact piece 6 b, a drainage groove 10 is formed at the contact portion between the operation leg 3 and the bush 6. Therefore, it is possible to prevent water from staying and prevent freezing in winter.
[0019]
The dimensions of the bush 6 and the protrusion 5 are determined as follows. For ease of explanation, the handle body 2 is chrome-plated, and the handle case 1 has two types: a surface treatment-free type and a paint-treated specification. It is assumed that the handle body is configured by connecting the handle body 2 to the handle case 1. Under the above-mentioned conditions, the dimension of the leg insertion hole 4 in the deflection direction varies depending on the surface treatment specifications. The cause of the change is not only the coating thickness, but also the shrinkage after molding between a highly active resin material used for surface treatment and a resin material with excellent weather resistance that can be used without surface treatment. There are differences in rates. For ease of explanation, here, assuming that only the coating thickness (t) is a factor, as shown in FIGS. 1B and 1C, the protrusion height of the protrusion 5 from the predetermined reference surface Is higher by the coating thickness (t) when the surface treatment is performed than when the surface treatment is not performed. The protrusion 5 is designed and manufactured so as to abut on the operation leg 3 of the handle body 2 in a state where the surface treatment is performed. When the handle case 1 is used to manufacture the handle device, FIG. As shown in FIG. 5, the shakiness of the steering direction of the handle can be prevented by using only the protrusion 5 without using the bush 6.
[0020]
On the other hand, the bush 6 is designed so that the protrusion height from the reference surface matches the maximum protrusion height of the protrusion 5, and when the protrusion height of the protrusion 5 is low because it is not coated. As shown in FIG. 1C, the bush 6 is attached to the holding portion 7, and the shaking of the steering direction of the handle can be suppressed by the bush 6.
[0021]
Therefore, in this embodiment, only one type of bush 6 is used, and the use or non-use of the bush 6 is determined depending on the specification of the surface treatment of the handle case 1 (in this embodiment, the presence or absence of surface treatment). For this reason, in the assembling operation, it is only necessary to determine whether or not the bush 6 is used from the surface treatment state.
[0022]
In the above description, a case has been described in which the handle device is configured using either one of two different types of surface treatment specification handle cases 1 in which the interval between the protrusions 5 changes. ), Even if two or more types of handle cases 1 are used, if the mounting reference portion 11 of the bush 6 that does not change in dimensions due to the difference in surface treatment specifications is set, the coating film is t1, Even if it changes with t2, the change of a dimension can be absorbed only by the presence or absence of use of one kind of bush 6. FIG. The attachment reference part 11 can be easily set by, for example, masking the part in the painting process.
[0023]
Furthermore, in the above description, the case where the surface treatment specification on the handle main body 2 side is one type is exemplified, but there are a plurality of types of surface treatment specifications of the handle main body 2 and variations in the dimensions of the operation leg 3 occur. The dimensions of the protrusion 5 may be set so as to contact the operating leg 3 when the gap between the leg insertion hole 4 and the operating leg 3 is minimized.
[0024]
