Description

Stopper for sliding door

The present invention relates to a stopper for a sliding door that regulates the swing of the sliding door with respect to the vehicle body when the sliding door that is slid with respect to the vehicle body is fully closed.

Conventionally, some automobiles such as minivans have a sliding door. The sliding door is slid with respect to the vehicle body to open and close. Even if the sliding door is in a fully closed state, it may swing with respect to the vehicle body due to acceleration / deceleration of the automobile or traveling on a rough road. With respect to such a shake, an automobile including the above-described slide door is provided with a slide door stopper that regulates the shake of the slide door with respect to the vehicle body (see, for example, Patent Document 1).

The disclosed slide door stopper includes a mail installed on either the vehicle body or the slide door and a mail installed on either the vehicle body or the slide door. The stopper for the slide door functions as a stopper for restricting the swing of the slide door with respect to the vehicle body by fitting the mail to the mail.
Further, in the above-described stopper for the sliding door, the mail becomes thinner toward the tip in order to smooth the fitting between the mail and the mail when the sliding door is slid to close. The female has a shape that expands toward the open end.

However, in the above-described stopper for the sliding door, there is a case where the fitting between the mail and the mail is displaced due to the force of the slide for closing the sliding door. If there is a discrepancy between the fitting of Himal and E-mail in this way, a gap will be created in the fitting, and the sliding door will rattle due to acceleration / deceleration of the car or driving on a rough road, and a rattling noise (abnormal noise) will occur. There was a case that would cause the occurrence of.
Further, in the case of the slide door stopper described above, when the force of the slide to close the slide door is strong, the next time the slide door is opened, the elastic restoring force of the fitting part is used. In some cases, it may cause abnormal noise to be restored.

The present invention has been made in view of such circumstances, and a problem to be solved by the present invention is that the body of the sliding door is in a fully closed state of the sliding door that is slid with respect to the body of the vehicle. This is a sliding door stopper that regulates the swing of the slide body, and when sliding the slide door to close, smoothes the fitting of the mail to the email and regulates the slide door's swing to the body. It is possible to improve the quietness by suppressing the generation of noise during traveling and opening and closing.

In order to solve the above problems, the sliding door stopper according to the present invention employs the following means.
That is, the sliding door stopper according to the first aspect of the present invention is a sliding door that regulates the swinging of the sliding door with respect to the vehicle body when the sliding door that is slid with respect to the vehicle body is fully closed. A stopper that is installed on either the vehicle body or the sliding door and includes a fitting male member; and the fitting male member that is installed on the other of the vehicle body or the sliding door. The fitting male member includes a fitting female member, and the fitting male member includes an outer peripheral contact surface extending in a fitting direction with respect to the fitting female member, and the outer peripheral contact surface. An insertion tip having a reduced outer diameter, and the fitting female member is formed of elastic rubber, and when the fitting male member is fitted together, The inner peripheral contact surface is in close contact with the outer peripheral contact surface, and a plurality of grooves extending along the fitting direction of the fitting male member are formed on the inner peripheral contact surface. To do.

According to this sliding door stopper, the distal end portion for insertion of the fitting male member has a reduced outer diameter compared to the outer peripheral contact surface. Therefore, when fitting the fitting male member to the fitting female member, Even if there is a slight deviation from the exact fitting position, the insertion tip can be allowed, and the fitting male member can be easily fitted into the fitting female member.
Further, the fitting female member is formed of elastic rubber, and a plurality of grooves extending along the fitting direction of the fitting male member are formed on the inner peripheral contact surface of the fitting female member. When fitting the male member to the fitting female member, the inner peripheral contact surface of the fitting female member can be elastically deformed across the gap in the groove. This makes it easy to fit the fitting male member to the fitting female member.

Further, according to the stopper for the sliding door, after the fitting male member is fitted to the fitting female member, the inner peripheral abutting surface of the fitting female member is engaged with the fitting male member by its elastic restoring force. The outer peripheral contact surface of the member and the inner peripheral contact surface of the fitting female member can be brought into close contact with each other. Since the outer peripheral contact surface and the inner peripheral contact surface that are in close contact with each other extend along the fitting direction of the fitting male member to the fitting female member, Movement in a direction other than the fitting direction can be restricted, and thereby the swing of the sliding door relative to the vehicle body can be restricted.
Therefore, when the sliding door is slid to close, the fitting male member can be smoothly fitted to the fitting female member, and the sliding door can be restricted from swinging with respect to the vehicle body. Since the fitting of the fitting male member to the fitting female member to be regulated is in close contact, it is possible to improve quietness by suppressing the generation of abnormal noise during traveling and opening and closing.

The sliding door stopper according to a second invention is the sliding door stopper according to the first invention, wherein the female member accommodates and holds the fitting female member and an outer peripheral surface of the fitting female member. A bracket is provided that closely contacts and supports the outer peripheral surface.
According to this slide door stopper, the female is provided with a bracket that accommodates and holds the fitting female member and that is in close contact with the outer circumferential surface of the fitting female member to support the outer circumferential surface. Even if the fitting female member swings with a strong force, the bracket is in close contact with the outer peripheral surface of the fitting female member to support the outer peripheral surface. Can be regulated.
As a result, for example, when the automobile travels on a rough road, even if the swing of the fitting male member relative to the fitting female member is so strong that the fitting female member alone cannot be regulated, The swing of the fitting male member with respect to the fitting female member can be restricted by the supporting force, and the shaking with respect to the vehicle body of the sliding door can be prevented.

According to the stopper for the sliding door according to the first aspect of the invention, the fitting of the fitting male member to the fitting female member when the sliding door is slid to close is made smooth, and the fitting female member is fitted. Since the fitting of the fitting male member can be in close contact with the sliding door and the swinging of the sliding door with respect to the vehicle body can be restricted, the generation of noise during running and opening / closing can be suppressed to improve quietness.
According to the stopper for the sliding door according to the second aspect of the invention, even if the swing of the fitting male member relative to the fitting female member is so strong that the fitting female member cannot be restricted by the fitting female member alone, the bracket is supported. The force can regulate the swing of the fitting male member relative to the fitting female member, and can prevent the sliding door from swinging with respect to the vehicle body.

The movement of the fitting female member 55 is restricted by the support force of the support edge portions 52a, 52b, 52c, and 52d.

According to the slide door stopper 30 configured as described above, the following operational effects can be obtained.
According to the slide door stopper 30, the insertion distal end portion 48 of the fitting male member 45 has an outer diameter reduced compared to the outer circumferential contact surface 47. Even when the fitting position is slightly shifted from the correct fitting position, the insertion distal end portion 48 can tolerate this, and the fitting male member 45 is fitted to the fitting female member 55. It shall be easy to make.
Further, the fitting female member 55 is formed of elastic rubber, and a plurality of grooves 56 b extending along the fitting direction H of the fitting male member 45 are formed on the inner peripheral contact surface 56 a of the fitting female member 55. Therefore, when the fitting male member 45 is fitted to the fitting female member 55, the inner peripheral contact surface 56a of the fitting female member 55 can be elastically deformed across the gap of the groove 56b. it can. Thus, the fitting male member 45 can be easily fitted into the fitting female member 55.

Further, according to the stopper 30 for the sliding door, after the fitting male member 45 is fitted to the fitting female member 55, the inner peripheral abutment surface 56a of the fitting female member 55 has its elastic restoring force. Thus, the outer peripheral contact surface 47 of the fitting male member 45 and the inner peripheral contact surface 56a of the fitting female member 55 can be brought into close contact with each other. Since the outer peripheral contact surface 47 and the inner peripheral contact surface 56 a that are in close contact with each other extend along the fitting direction H of the fitting male member 45 with the fitting female member 55, the fitting male member 45. The movement in the direction other than the fitting direction H with respect to the fitting female member 55 can be restricted, and thereby the swing of the sliding door 20 with respect to the vehicle body 11 can be restricted.
Therefore, when the sliding door 20 is slid to be closed, the fitting of the fitting male member 45 to the fitting female member 55 can be smoothly performed, and the swing of the sliding door 20 with respect to the vehicle body 11 can be restricted. Since the fitting of the fitting male member 45 to the fitting female member 55 that regulates this deflection is in close contact with each other, it is possible to improve the quietness by suppressing the generation of noise during traveling and opening and closing. Can do.

In addition, according to the slide door stopper 30, the female 50 accommodates and holds the fitting female member 55, and is in close contact with the outer circumferential surface 57 of the fitting female member 55 to support the outer circumferential surface 57. Since the female bracket member 51 having 52 is provided, even if the fitting male member 45 swings with a strong force against the fitting female member 55, the housing holding portion 52 is provided. Since the female bracket member 51 to be in close contact with the outer peripheral surface 57 of the fitting female member 55 supports the outer peripheral surface 57, it is also possible to restrict the vibration due to this strong force.
For example, even when the sliding door 20 swings upward with a strong force with respect to the vehicle body 11, the outer peripheral surface 57 a of the fitting female member 55 does not elastically deform. The inner peripheral surface 58a of 52a is closely attached and supported. Thereby, the upward movement of the fitting male member 45 relative to the fitting female member 55 can be restricted, and the upward swing of the slide door 20 relative to the vehicle body 11 can be restricted.
Even when the sliding door 20 swings with a strong force laterally or downward with respect to the vehicle body 11, the outer peripheral surfaces 57b, 57c, 57d of the fitting female member 55 are elastically deformed. The support edge portions 52b, 52c, and 52d of the supporting edge portions 52b, 52c, and 52d that do not occur are supported in close contact. Thereby, the sideward and downward movement of the fitting male member 45 with respect to the fitting female member 55 can be restricted, and the sideward and downward deflection of the slide door 20 with respect to the vehicle body 11 can be restricted. .
Therefore, for example, when the automobile 10 travels on a rough road, even if the swing of the fitting male member 45 with respect to the fitting female member 55 is so strong that the fitting female member 55 cannot be restricted by itself. The swing of the fitting male member 45 relative to the fitting female member 55 can be restricted by the supporting force of the female bracket member 51 provided with the housing holding portion 52, and the swing of the sliding door 20 relative to the vehicle body 11 can be prevented. it can.

The sliding door stopper according to the present invention is not limited to the above-described embodiment, and can be appropriately changed without changing the gist of the present invention.
That is, in the above-described embodiment, an example in which the mail 40 is installed in the vehicle body 11 and the mail 50 is installed in the slide door 20 is described, but the slide door stopper according to the present invention is Without being limited to this example, the mail may be installed on the slide door and the mail may be installed on the vehicle body.
Further, the installation positions of these mails and emails are not limited to the above example, and appropriate positions can be selected.

Moreover, although the groove | channel 56b provided in the fitting female member 55 in above-described embodiment was formed so that it might extend straight along the fitting direction H of the fitting male member 45, it is set to this invention. The groove provided in the fitting female member is not a problem as long as it is formed so as to extend along the fitting direction of the fitting male member. For example, a curved shape such as a spiral shape may be selected. However, in view of the molding process, the case where the fitting male member 45 extends straight along the fitting direction H as in the above-described embodiment is advantageous because it can be easily and inexpensively manufactured.
