Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention increases the turning resistance acting on the door when the door reaches the half-open position when opening the door pivotally supported on the vehicle body so that the door can be opened and closed, and the door unexpectedly turns to the fully open position. The present invention relates to a door check device for an automobile having a function of preventing the door from being closed and stopping the door when the door is turned to a fully open position.
[0002]
[Prior art]
It has been well known that the door check device is provided between a vehicle body and a door in order to enhance operability when the door is opened and closed (for example, see Japanese Utility Model Publication No. 63-11269). Such a door check device includes a guide arm having one end pivotally attached to a vehicle body, and a sliding body slidably fitted to the guide arm. A sliding member that moves in the longitudinal direction of the guide arm while contacting the outer surface of the guide arm when the sliding member slides, supports the sliding member, and And a support fixed to the support.
[0003]
When the door is in the fully closed position, the sliding member of the sliding body is located at one end of the guide arm, and the door rotates from the fully closed position to the half-open position, and the sliding member is thereby moved to the protrusion of the guide arm. When it reaches, the sliding member presses the protrusion. As a result, the frictional force acting between the sliding member and the guide arm is increased, a large turning resistance is applied to the door, and the door stops at the half-open position. In this manner, it is possible to prevent the door from rotating to the fully opened position at a stretch.
[0004]
When further turning force is applied to the door, the sliding member climbs over the projection of the guide arm to the other end of the guide arm, and the door occupies the fully open position. At this time, the support of the slide comes into contact with a stopper provided on the other end of the guide arm, whereby the door is stopped at its fully open position. When closing the door, the reverse operation is performed.
[0005]
In the conventional door check device configured as described above, the stopper is constituted by a plate material fixedly attached to the other end of the guide arm, and when the door is turned to the fully open position, the support of the sliding member is The stopper is configured to contact the receiving surface of the stopper. At the time of the contact, the receiving surface of the stopper and the contact surface of the support are parallel to each other, and the two contact each other with a large area, so that a large stress is not generated in the stopper.
[0006]
However, when the assembly tolerance of the stopper with respect to the guide arm, the assembly tolerance of the guide arm with respect to the vehicle body, and the stacking tolerance of the assembly of the sliding body with respect to the door, the contact surface of the support hits the receiving surface of the stopper. Both could not maintain a parallel positional relationship, and there was a risk that a so-called one-sided contact would occur where they abut locally.
[0007]
When such a one-sided contact occurs, a large external force is locally applied to the stopper, so that a large noise is generated when the support and the stopper come into contact with each other. Further, since a large stress is generated in the stopper, it is necessary to set its strength and size large in order to prevent it from being damaged at an early stage, but this inevitably increases the cost of the stopper.
[0008]
Further, there is also known a door check device in which a stopper is constituted by a stopper pin fixed to a guide arm and a stopper plate positioned adjacent to the stopper pin and fitted with play to the guide arm (for example, Japanese Patent Application No. Hei 7 (1994) -197716). 219824). According to this configuration, when the support of the sliding member comes into contact with the stopper plate, the stopper plate is loosely fitted to the guide arm so that the stopper plate can move slightly. The support of the moving body can be prevented from hitting one side. However, according to this configuration, since the stopper is composed of a plurality of members, the number of parts of the door check device increases, and the disadvantage of increasing the cost is unavoidable.
[0009]
[Problems to be solved by the invention]
The present invention has been made based on the above-described novel recognition, and an object of the present invention is to prevent a contact between a support of a sliding body and a stopper and to prevent an increase in the number of parts in an automobile door check. It is to provide a device.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a guide arm having one end rotatably pivotally attached to a vehicle body and having a projection projecting outward at an intermediate portion in a longitudinal direction thereof; A sliding body fitted slidably in the longitudinal direction thereof, and a stopper provided on the other end side of the guide arm, wherein the sliding body is fixed to a door pivotally supported by a vehicle body. The guide arm is supported by the support and moves in the longitudinal direction of the guide arm while contacting the outer surface of the guide arm when the slide body slides on the guide arm in accordance with the opening and closing operation of the door. A sliding member, wherein when the door is at the fully closed position, the sliding member of the sliding body is located at one end of the guide arm, and the door pivots from the fully closed position to the half-opened position to rotate the sliding body. When the sliding member reaches the protrusion of the guide arm When the sliding member presses the protrusion, the turning resistance of the door is increased, and when the door is turned to the fully open position, the sliding member of the sliding body moves beyond the protrusion of the guide arm and the other end of the guide arm. A door check device for an automobile in which the support body comes into contact with the stopper, the stopper being fitted to the guide arm so as to be rotatable around an axis substantially perpendicular to an outer surface of the guide arm; And a receiving part formed integrally with the base and having a receiving surface with which the contact surface of the support comes into contact when the door is turned to its fully opened position.

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings, and the above-mentioned conventional disadvantages will be more specifically clarified with reference to the drawings.
[0012]
FIGS. 1 to 3 show an example of an automobile door check device, and FIGS. 4 and 5 are plan sectional views schematically showing a state where the door check device is assembled to a vehicle body and a door. The door check device for an automobile shown in these figures has a guide arm 1 and a slide 2 fitted to the guide arm 1 so as to be slidable along the longitudinal direction. The guide arm 1 of the present embodiment is constituted by arm members 3 and 4 formed of a pair of plate members superimposed on each other. The guide arm 1 is formed by folding a single plate material into two, and overlapping the two sides thereof. A guide arm can also be configured. Further, the guide arm 1 can be formed by only one plate material that is not superimposed.
[0013]
A mounting hole 5 is formed at one end 101 in the longitudinal direction of both arm members 3 and 4 constituting the guide arm 1, that is, at the left end in FIG. As shown in FIGS. 4 and 5 and in FIG. 1 by a dashed line, a bracket 27 is fixed to a pillar 26 of a vehicle body 25 of the automobile, and a hole 28 formed in the bracket 27 and the mounting hole 5 described above. Is fitted with a pivot pin 29. As described above, the guide arm 1 is rotatably pivotally attached to the vehicle body 25 at one end 101 in the longitudinal direction, and can swing around a pivot pin 29 in a horizontal plane. A stopper 6, which will be described in detail later, is provided on the other end side 102 in the longitudinal direction of the two arm members 3 and 4, that is, on the right end side in FIG.
[0014]
The guide arm 1 made of a plate material has a protruding portion 7 protruding outward at an intermediate portion in the longitudinal direction, and in the illustrated example, a mountain-like shape in which the longitudinal intermediate portions of the arm members 3 and 4 are separated from each other. The projections 7 are formed by these mountain-shaped portions.
[0015]
On the other hand, the sliding body 2 is arranged between a case-shaped support body 8 composed of a main body 11 and a cover 12, a pair of upper and lower cushion members 9 and 10 housed therein, and between the cushion members 9 and 10. The sliding members 13 and 14 are provided, and the cushion members 9 and 10 and the sliding members 13 and 14 are supported by the support 8. As shown in FIG. 1, the two sliding members 13 and 14 are assembled so as to overlap each other, and the guide arm 1 is inserted into a gap therebetween. In this manner, the sliding members 13 and 14 abut against the outer surface 21 of the guide arm 1 and are accommodated inside the support 8 so as to be movable in the direction S (FIG. 1) approaching or separating from the outer surface. ing.
[0016]
Each of the cushion members 9 and 10 supported by the support body 8 is made of an elastic body such as rubber, for example, and each of the sliding members 13 and 14 that contact the outer surface 21 of the guide arm 1 is opposite to the contact surfaces 23 and 24 of the sliding members 13 and 14. The sliding members 13 and 14 are located adjacent to the sliding member back surfaces 23A and 24A, and press the sliding members 13 and 14 against the outer surface 21 of the guide arm 1 by their elasticity. The sliding members 13 and 14 of this example are made of a material having a small coefficient of friction with respect to the guide arm 1, for example, a resin such as polyacetal. The guide arm 1 is also made of resin such as polyacetal or metal.
[0017]
As shown in FIGS. 1 to 3, the guide arm 1 passes through an opening 15 formed in the cover 12, a gap between the sliding members 13 and 14, and an opening 16 formed in the main body 11 of the support 8. Extending, the support 8 does not contact the guide arm 1. Mounting holes 17 and 18 are formed on the cover 12 and the main body 11 of the support body 8 at upper and lower sides, respectively, as shown in FIGS. 4 and 5 and shown by a dashed line in FIG. , 18 is fixed to an inner panel 33 of a door 32 pivotally supported by a vehicle body 25 via a hinge pin 31 so as to be able to open and close by a screw 30 and a nut screwed to the screw 30. I have. The support 8 is disposed inside the door 32 and is fixed to the inner panel 33. The other end 102 of the guide arm 1, that is, the free end thereof, passes through the opening 34 formed in the inner panel 33, and Has penetrated inside.
[0018]
When the door 32 is closed as shown in FIG. 4, the slide 2 is stopped at the initial position shown by the two-dot chain line in FIG. When the door 32 is in the fully closed position, the sliding members 13 and 14 of the sliding body 2 are located at one end 101 of the guide arm 1 in the longitudinal direction.
[0019]
When the door 32 starts to be opened, the support 8 fixed to the door 32 along with the cushion members 9 and 10 and the sliding members 13 and 14 supported along the guide arm 1 pivotally attached to the vehicle body 25. It relatively moves to the right in FIG. When the sliding body 2 slides on the guide arm 1, the sliding members 13, 14 move along the longitudinal direction of the guide arm 1 while their opposing contact surfaces 23, 24 abut against the outer surfaces 21 of the guide arm 1. Move.
[0020]
When the door 32 is rotated to a half-open position, that is, to a predetermined angle position between the fully closed position and the fully open position, the sliding body 2 moves the protrusion 7 of the guide arm 1 as shown by a broken line in FIG. It reaches the top 22. That is, when the door 32 rotates from the fully-closed position to the half-open position, the sliding members 13 and 14 of the sliding body 2 reach the top 22 of the projection 7 of the guide arm 1. The two sliding members 13 and 14 move in a direction away from each outer surface of the guide arm 1 because they protrude largely outward as compared with the guide arm portion of the guide arm 1. For this reason, each of the cushion members 9 and 10 made of an elastic body is compressed and deformed as shown by a broken line in FIG. At this time, the sliding members 13 and 14 and / or the guide arm 1 may be configured to be elastically deformed.
[0021]
Due to the elasticity of the cushion members 9 and 10 compressed and deformed in this way, the frictional resistance between each of the sliding members 13 and 14 and each of the outer surfaces 21 of the guide arm 1 is further increased. The sliding members 13 and 14 press the projection 7, and a greater frictional force acts between the sliding members 13 and 14 and the guide arm, so that the turning resistance of the door is increased. For this reason, it can be prevented that the door is suddenly opened to its fully opened position at once.
[0022]
When the turning power is continuously applied to the door 32, the sliding members 13 and 14 of the sliding body 2 get over the protrusion 7. When the door 32 rotates to the fully open position shown in FIG. 5, the sliding body 2 reaches the terminal position shown by the solid line in FIG. As described above, when the door 32 is rotated to the fully open position, the sliding members 13 and 14 of the sliding body 2 reach the other end 102 in the longitudinal direction of the guide arm 1 beyond the protrusion 7 of the guide arm 1. When the sliding members 13 and 14 leave the projection 7, the compressed and deformed cushion members 9 and 10 return to their original forms due to their elasticity.
[0023]
When the door 32 reaches the fully open position, the main body 11 of the support 8 hits the stopper 6, and the door 32 is stopped at the fully open position. When the door 32 is closed, the operation opposite to that described above is performed. When the door 32 reaches the fully closed position as shown in FIG. 4, the sliding member 2 is moved to the initial position shown by the two-dot chain line in FIG. Return to
[0024]
The cushion members 9 and 10 are omitted, and the sliding members 13 and 14 or the guide arm 1 or both of them are elastically deformed when the sliding members 13 and 14 reach the protrusion 7 of the guide arm 1. You can also.
[0025]
As described above, the vehicle door check device of the present embodiment has the one end 101 pivotally connected to the vehicle body 25 and has the protruding portion 7 protruding outward at the longitudinal middle portion thereof. A guide arm 1, a sliding body 2 fitted to the guide arm 1 so as to be slidable in the longitudinal direction, and a stopper 6 provided on the other end side 102 of the guide arm 1 are provided. A support member 8 fixed to a door 32 pivotally supported by a vehicle body 25, and a support member 8 supported by the support member 8, when the sliding member 2 slides on the guide arm 1 accompanying the opening and closing operation of the door 32. Sliding members 13 and 14 that move in the longitudinal direction of the guide arm 1 while being in contact with the outer surface 21 of the guide arm 1. When the door 32 is in the fully closed position, the sliding members 13 and 14 of the sliding body 2 are provided. Is located at one end side 101 of the guide arm 1 and has a door When the sliding member 2 rotates from the fully closed position to the half-open position and the sliding members 13 and 14 of the sliding body 2 reach the projection 7 of the guide arm 1, the sliding members 13 and 14 press the projection 7 to open the door. When the rotation resistance of the sliding arm 32 is increased and the door 32 is rotated to the fully open position, the sliding members 13 and 14 of the sliding body 2 move beyond the protrusion 7 of the guide arm 1 to the other end 102 of the guide arm 1. Finally, the support 8 is configured to contact the stopper 6.
[0026]
Here, the stopper 6 provided on the other end side 102 of the guide arm 1 functions to stop the door 32 at the fully open position as described above. However, in the conventional door check device, FIG. Since the stopper 6A is fixed by the plate material fixed to the guide arm 1 as shown in FIG. 5, when the door is turned to the fully open position due to the accumulation of the assembly tolerance of each element of the door check device, The receiving surface 35A of the stopper 6A and the contact surface 36A of the support 8 are not parallel to each other, and there is a possibility that the contact occurs only at a local portion indicated by reference numeral 6B.
[0027]
Therefore, in the door check device of the present embodiment, as shown in FIGS. 1 to 6, the stopper 6 is formed by cutting out a part of a cylindrical body and forming a base 37 having a substantially C-shaped cross section. The base 37 has a receiving portion 38 formed integrally therewith. The receiving portion 38 includes a central portion 39 having a substantially C-shaped cross-sectional shape formed integrally and continuously with the base portion 37, and a pair of flat plate portions 40 integrally projecting from the central portion 39. The flat plate portion 40 constitutes a receiving surface 35 with which the support 8 of the sliding body 2 comes into contact.
[0028]
A circular through hole 41 is formed in the other end side 102 of the guide arm 1, and the base 37 of the stopper 6 is rotatably fitted in the through hole 41. In this way, the base 37 is fitted to the guide arm 1 so as to be rotatable about an axis X substantially perpendicular to the outer surface 21 thereof.
[0029]
As described above, when the door 32 reaches the fully open position, the support 8 of the sliding body 2 comes into contact with the stopper 6, and at this time, as shown in FIG. The flat receiving surface 35 formed by the receiving portion 36 and the receiving portion 38 of the stopper 6 is positioned parallel to each other, and these surfaces come into contact with each other. As described above, since the stopper 6 and the support body 8 come into contact with each other in a large area, excessive stress is not generated in the stopper 6.
[0030]
Moreover, as shown in FIG. 6, even if the receiving surface 35 of the stopper 6 is not parallel to the contact surface 36 of the support 8 before the support 8 contacts the stopper 6, As the support 8 comes into contact with the stopper 6, the stopper 6 corrects its posture while rotating around the central axis X of the through hole 41 by the external force received from the support 8, and finally, The receiving surface 35 and the contact surface 36 contact each other in a large area in a state where they are parallel to each other.
[0031]
As described above, the stopper 6 is formed integrally with the base 37 so as to be rotatable about the axis X substantially perpendicular to the outer surface 21 of the guide arm 1, and the stopper 32 is formed integrally with the guide arm 1. Has a receiving portion 38 having a receiving surface 35 with which the contact surface 36 of the support 8 comes into contact when it is rotated to its fully open position, so that the components of the door check device are assembled. The support 8 of the sliding body 2 and the stopper 6 can be always brought into contact with a large area without being affected by the above-mentioned tolerance, and it is possible to prevent one contact between the two. For this reason, a large external force is not locally applied to the stopper 6, and no large abnormal noise is generated at the time of the contact. Moreover, a large stress is not locally generated in the stopper 6, so that there is no need to particularly increase the size and strength, and the cost can be reduced.
[0032]
In addition, the stopper 6 does not need to be constituted by a large number of members, and may basically be constituted only by the base portion 37 and the receiving portion 38 integral therewith. A reduction in the number of points and a reduction in the cost can be achieved.
[0033]
The form of the stopper 6 can be appropriately changed. For example, as shown in FIGS. 7 and 8, a flange 42 can be formed at each circumferential end of the base 37 having a substantially C-shaped cross section.
[0034]
As shown in FIGS. 9 and 10, a protrusion 43 extending annularly and projecting outward in the radial direction is formed on the outer peripheral surface of the base 37 to prevent the base 37 from coming out of the through hole 41. You can also. Further, as shown in FIGS. 11 and 12, a projection 44 whose part is cut and raised may be formed on the base 37, thereby preventing the base 37 from coming out of the through hole 41. . The projection 43 and the projection 44 constitute specific examples of escape prevention means for preventing the stopper 6 from coming out of the guide arm.
[0035]
7, a cushion member 45 made of an elastic material such as rubber is fixed to the receiving surface 35 of the receiving portion 38, and the supporting member 8 is fixed to the receiving surface 35 via the cushion material 45. The contact surface 36 may be contacted to further reduce the impact at the time of contact.
[0036]
Although the embodiment of the present invention has been described above, the present invention can be widely applied to other types of door check devices.
[0037]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, a support body and a stopper can always contact on a large surface, without being affected by the tolerance in assembling the components of a door check apparatus, and it can prevent the one-sided occurrence. . This prevents generation of loud noise at the time of contact between the support and the stopper, and can set the strength and size of the stopper smaller than before, thereby reducing the cost of the door check device.
