DETAILED DESCRIPTION OF THE INVENTION
(overall structure)
The overall structure of the door check will be described with reference to FIG. 2 which is a perspective view of the door check of the present embodiment. 101 is a body bracket provided on the vehicle body side, and 102 is a case provided on the door side.
[0020]
Reference numeral 103 denotes an arm whose one end is rotatably connected to the body bracket 101 using a pin 108, and the other end is an arm that penetrates the case 102 and can advance and retreat with respect to the case 102.
[0021]
A stopper plate 105 is attached to the other end of the arm 103 protruding from the case 102 via a stopper cushion 104 to prevent the arm 103 from coming off.
(Arm and stopper plate)
As shown in FIG. 3, the stopper plate 105 includes a fitting leg 105a, outer legs 105b and outer legs 105c provided on both sides of the fitting leg 105a, and fitting legs 105a and outer legs 105b and 105c. It has a substantially E shape including a bridging portion 105d that bridges one end side.
[0022]
The arm 103 and the stopper plate 105 are attached by fitting the fitting leg portion 105a of the stopper plate 105 into the rectangular hole 103e formed on the other end side protruding from the case 2 of the arm 103, and the outer leg portion. This is done by caulking 105b and 105c in the width direction.
(Case)
As shown in FIG. 2, a concave portion 103a sandwiched between convex portions 103b is formed in the middle portion of the two opposing surfaces (upper surface and lower surface) of the arm 103, and the concave portion 3a is formed in the case 102. An engagement / disengagement mechanism capable of engagement / disengagement is provided.
[0023]
The periphery of the case 102 will be described with reference to FIG.
The case 102 includes a base portion 102b attached to the door side and a bottomed hole portion 102c in which a hole 102a through which the arm 103 is inserted is formed in the bottom portion.
[0024]
In the bottomed hole portion 102 c of the case 102, a mechanism that can be engaged and disengaged with the concave portion 103 a of the arm 103 is provided. This mechanism urges the first and second shoes 112 and 112 ′ that can contact the upper and lower surfaces of the arm 103 and the first and second shoes 112 and 112 ′ toward the upper and lower surfaces of the arm 13. The first and second cushions 114 and 114 'are made of an elastic body.
[0025]
The opening 102e of the bottomed hole 102c of the case 102 is covered with a metal cover 110.
The cover 110 is formed with a hole 110a through which the arm 3 is inserted so as to face the hole 102a of the bottomed hole 102c of the case 102.
[0026]
The arm 103 of the present embodiment is a resin layer 103d that covers the main body 103c in order to improve the aesthetic appearance of the main body 103c made of metal and the arm 103 and reduce friction between the first and second shoes 112 and 112 '. It is made up of.
[0027]
A seal member 111 made of a material such as an elastic resin or rubber is attached to the hole 110a of the cover 110 in order to prevent dust and foreign matter from entering the cover 110.
[0028]
The operation of the door check with the above configuration will be described.
As the door moves in the opening direction or in the closing direction, the arm 103 moves forward and backward with respect to the case 102. When the first and second shoes 112, 112 'get over the convex portion 103b or 103c of the arm 103 and engage with the concave portion 103a, the opening and closing of the door is temporarily prohibited and the door is checked.
[0029]
Further, when the door is moved in the opening direction or the closing direction, the shoe 112 gets over the convex portion 103b or 103c of the arm 13, and the movement of the door in the opening direction or the movement in the closing direction is continued.
(Case manufacturing method)
Assembling the door check case 102 according to the present embodiment having such a configuration is performed by integrating the first and second shoes 112 and 112 ′ using the connecting member 211 as shown in FIG. 212 and an integrated cushion 214 in which the first and second cushions 114 and 114 ′ are integrated using the connecting member 213.
[0030]
The connecting member 211 of the integrated shoe 212 and the connecting member 213 of the integrated cushion 214 are portions other than the space through which the arm 103 is inserted, in the present embodiment, both sides of the first and first shoes 112, 112 ′, the first And provided on both sides of the second cushion 114, 114 '.
[0031]
As shown in FIG. 5 which is an enlarged view of a portion C in FIG. 1, a notch 211a is formed in an intermediate portion of the connection member 211 for integrating the first and first ′ shoes 112 and 112 ′. .
[0032]
As shown in FIG. 1, a notch 213a is formed in an intermediate portion of the connection member 213 that integrates the first and second cushions 114 and 114 ′.
The integrated shoe 212 and the integrated cushion 214 are assembled in a shape as shown in FIG. 6, and this is set to the bottomed hole 102 c from the opening 102 e of the case 102, and the opening 102 e of the case 102 is closed using the cover 110, The arm 103 is inserted through the hole 110 a of the cover 110.
[0033]
By the insertion of the arm 103, the notch 211a of the connecting member 211 of the integrated shoe 212 and the notch 213a of the connecting member 213 of the integrated cushion 214 are broken, and the integrated shoe 212 is moved to the first and second shoes 112, 112 ′. The integral cushion 214 is divided into first and second cushions 114, 114 ', respectively.
[0034]
According to the above manufacturing method, the first and second shoes 112 and 112 ′ and the first and second cushions 114 and 114, that is, four members are assembled in the case 102 as compared with the conventional assembling operation. Since the integral shoe 212 and the integral cushion 214, that is, only two members need to be assembled, the number of assembling steps can be reduced.
[0035]
Further, by providing the notch 211a in the connecting member 211 of the integrated shoe 212 and the notch 213a in the connecting member 213 of the integrated cushion 214, the connecting members 211 and 213 can be easily broken when the arm 103 is inserted. Can do.
[0036]
【The invention's effect】
As described above, according to the first aspect of the present invention, compared to the work of assembling the first and second shoes and the first and second urging members, that is, the four members, in the case, Since it is only necessary to assemble the integral shoe and the integral urging member, that is, two members, the number of assembling steps can be reduced.
[0037]
According to the second aspect of the present invention, when the arm is inserted by providing the cutout portion in the connecting member of the integrated shoe and the integrated biasing member, the connecting member is easily broken.
