Description

[Technical field]

[0001] The present invention relates to a gasket and a handle arrangement. [Background technology]

[0002] Patent document 1 discloses a handle device provided with a sealing member equipped with a second cushioning piece that is interposed between the frame side stopper of the frame member and the outside handle and functions to reduce or absorb impact when the outside handle returns from the full stroke position to its initial position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-30984 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, higher noise reduction is required for the handle device. For this reason, it is difficult to obtain the required noise reduction by only providing a buffer part consisting of the second buffer piece, as in the handle device described in Patent Document 1. Although it is conceivable to improve the shock absorption by forming a slit in the buffer part, there is a risk of a hitting sound being generated when the slit is crushed by the outside handle returning to the initial position.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a gasket and a handle device that can sufficiently suppress hitting sounds when operating the handle. [Means for solving the problem]

[0006] The above object of the present invention can be achieved by the following configuration. (1) A gasket provided in a handle device including an operating handle that is pivotally attached to a door panel of a vehicle with one end as a fulcrum and that pivots between an initial position along the door panel and an operating position in which the other end is spaced apart from the door panel, the gasket being attached to a position on the door panel opposite the operating handle, a buffer portion protruding from a contact portion with the operating handle when the operating handle is returned from the operating position to the initial position; The buffer portion has a hollow portion that is open on the side opposite the operating handle.

[0007] According to the gasket having the above configuration (1), the operating handle that is returned from the operating position to the initial position abuts against the buffer part. This buffer part has a hollow part that is open on the side opposite to the operating handle, so that it deforms so as to be smoothly crushed when the operating handle abuts against it. Therefore, it is possible to effectively absorb the impact from the operating handle, and thereby to sufficiently suppress the hitting sound that occurs when the operating handle is returned to the initial position.

[0008] (2) The cavity of the buffer portion has an open side portion. The gasket described in (1) above.

[0009] According to the gasket having the above configuration (2), the buffer portion is deformed so as to be crushed more smoothly when the operating handle comes into contact with the buffer portion, and therefore the shock from the operating handle can be absorbed more effectively, and the generation of hitting noise can be further suppressed.

[0010] (3) The buffer portion has a protrusion that protrudes toward the operating handle. The gasket described in (1) above.

[0011] According to the gasket having the above configuration (3), the shock from the operating handle is received by the projection of the buffer part, and then the top surface of the buffer part is deformed so as to bend starting from the projection. Therefore, the shock from the operating handle can be smoothly absorbed, and the hitting sound generated when the operating handle comes into contact can be further suppressed.

[0012] (4) an operating handle that is pivotally attached to a door panel of a vehicle with one end as a fulcrum and that pivots between an initial position along the door panel and an operating position in which the other end is spaced apart from the door panel; The gasket according to any one of (1) to (3) above is attached to the door panel at a position facing the operating handle; and A handle device comprising:

[0013] According to the handle device having the configuration of (4) above, the shock-absorbing portion of the gasket can effectively absorb the impact received from the operating handle when it is returned from the operating position to the initial position, thereby making it possible to sufficiently suppress the impact noise generated when the operating handle is returned to the initial position. Effect of the Invention

[0014] According to the present invention, it is possible to provide a gasket and a handle device that can sufficiently suppress striking sounds generated when operating the handle.

[0015] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the following description of the embodiment of the present invention (hereinafter, referred to as "embodiment") with reference to the accompanying drawings.

[0019] 1 and 2, a handle device 100 according to this embodiment is attached to a vehicle door panel 1. In this embodiment, the handle device 100 provided on the left door of the vehicle will be described as an example.

[0020] The door panel 1 is an outer panel that constitutes a door of a vehicle. The handle device 100 includes a handle base 10, an operating handle 20, and a cylinder lock 30. The handle device 100 further includes a first gasket 40, a second gasket 50, and a cylinder cover 60.

[0021] The door panel 1 to which the handle device 100 is attached has a first opening 2 and a second opening 3. The first opening 2 and the second opening 3 are mounting holes for mounting the handle device 100 to the door panel 1. The first opening 2 is formed on the vehicle front FR side, and the second opening 3 is formed on the vehicle rear BC side. Between the first opening 2 and the second opening 3, the door panel 1 is formed with a recessed portion 4 into which an operator's hand enters when operating the handle device 100. The recessed portion 4 has a recessed shape recessed toward the inside of the door panel 1.

[0022] The handle base 10 is fixed to the inside of the door panel 1. The handle base 10 includes a first support portion 12 having a first support hole 11 and a second support portion 14 having a second support hole 13. By attaching the handle base 10 to the door panel 1 from the inside, the first support hole 11 of the first support portion 12 communicates with the first opening 2 of the door panel 1, and the second support hole 13 of the second support portion 14 communicates with the second opening 3.

[0023] The operating handle 20 is attached to and supported by the handle base 10 attached to the door panel 1 from the outside of the door panel 1. The operating handle 20 is formed in a rod shape. The operating handle 20 is composed of a grip main body 20A and a grip cover 20B that is attached so as to cover the outside of the grip main body 20A.

[0024] The grip body 20A is provided with a first engagement portion 25 at one end and a second engagement portion 26 at the other end. The grip body 20A and the grip cover 20B are assembled to the operating handle 20, and the other end of the grip body 20A having the first engagement portion 25 is the first mounting portion 21, and the other end of the grip body 20A having the second engagement portion 26 is the second mounting portion 22. The operating handle 20 is also provided with a gripping portion 23 between the first mounting portion 21 and the second mounting portion 22. The operating handle 20 is assembled to the handle base 10 attached to the door panel 1 with one end of the first mounting portion 21 facing the vehicle front FR and the other end of the second mounting portion 22 facing the vehicle rear BC.

[0025] The operating handle 20 has a first engagement portion 25 and a second engagement portion 26 of the grip body 20A that protrude in the direction of assembly to the handle base 10. The first engagement portion 25 and the second engagement portion 26 have engagement claws 25a, 26a that protrude toward the vehicle front FR side. The second engagement portion 26 has an extension portion 26b that extends in the direction of assembly to the handle base 10, and the engagement claw 26a is formed at the tip portion of the extension portion 26b.

[0026] The first engagement portion 25 of the operating handle 20 is inserted into the first support hole 11 of the first support portion 12 of the handle base 10, and the engagement claw 25a is engaged with the vehicle front FR side of the first engagement portion 25. The second engagement portion 26 of the operating handle 20 is inserted into the second support hole 13 of the second support portion 14 of the handle base 10, and the engagement claw 26a is engaged with the vehicle front FR side of the second engagement portion 26. The operating handle 20 is supported so as to be swingable with respect to the handle base 10 with the engagement point of the first engagement portion 25 on the first support portion 12 of the handle base 10 as a fulcrum. The operating handle 20 has a key hole portion 27 on the other end side, and the cylinder lock 30 can be operated by a key inserted into the key hole portion 27.

[0027] The cylinder lock 30 is fixed to the second support portion 14 of the handle base 10 fixed to the door panel 1. The cylinder lock 30 is fixed by screws in a state where it is fitted into the second support hole 13 of the second support portion 14 from the outside of the door panel 1. The cylinder lock 30 is disposed on the vehicle rear BC side of the insertion position of the second engagement portion 26 of the operating handle 20 in the second support hole 13.

[0028] The cylinder cover 60 is attached to the cylinder lock 30 from the outside of the door panel 1. The cylinder cover 60 is formed from, for example, a synthetic resin such as plastic. The cylinder cover 60 is attached so as to cover the periphery of the cylinder lock 30. The outsides of the cylinder cover 60 and the cylinder lock 30 are covered by the second mounting portion 22 of the operating handle 20. In other words, the handle device 100 is a seamless type in which an escutcheon portion that overlaps and covers the cylinder lock 30 on the operating handle 20 is provided integrally.

[0029] In the handle device 100 having the above structure, the operating handle 20 can be swung around the engaging point of the first engaging portion 25 with the first support portion 12 of the handle base 10 as a fulcrum. As a result, the operating handle 20 is swung between an initial position (position in FIG. 1) along the door panel 1 and an operating position where the rear end is separated from the door panel 1. That is, in the handle device 100, by gripping the gripping portion 23 of the operating handle 20 and pulling it toward oneself, the operating handle 20 is swung from the initial position to the operating position around the engaging point of the first engaging portion 25 with the first support portion 12 as a fulcrum. Also, when the operating handle 20 is released, it is swung from the operating position to the initial position around the engaging point of the first engaging portion 25 with the first support portion 12 of the handle base 10 as a fulcrum by an internal biasing means (not shown). In the handle device 100, by pulling the operating handle 20 toward oneself and swinging it to an operating position, a latch (not shown) of the door device is operated and the door is opened.

[0030] FIG. 3 is a perspective view of the door panel 1 to which the first gasket 40 and the second gasket 50 are attached.

[0031] As shown in FIG. 3, the first gasket 40 and the second gasket 50 are attached to the door panel 1. The first gasket 40 and the second gasket 50 are made of an elastic resin material such as polypropylene or synthetic rubber. The first gasket 40 is formed in an annular shape along the edge of the first opening 2 of the door panel 1, and is attached to the door panel 1 along the edge of the first opening 2. The first gasket 40 is disposed between the door panel 1 and the first mounting portion 21 of the operating handle 20 assembled to the handle base 10. The second gasket 50 is formed in an annular shape along the edge of the second opening 3 of the door panel 1, and is attached to the door panel 1 along the edge of the second opening 3. The second gasket 50 is disposed between the door panel 1 and the second mounting portion 22 of the operating handle 20 assembled to the handle base 10. The second gasket 50 has two buffer portions 51. These buffer portions 51 are bulged toward the second mounting portion 22 of the operating handle 20.

[0032] Fig. 4 is a perspective view of the second gasket 50 as viewed from the front side and a partially enlarged view. Fig. 5 is a perspective view of the second gasket 50 as viewed from the back side and a partially enlarged view.

[0033] 4 and 5, the buffer portion 51 provided in the second gasket 50 has a hollow portion 52 that is open on the side opposite to the second mounting portion 22 of the operating handle 20. This hollow portion 52 is open on the side that is the inside of the second gasket 50. In addition, the buffer portion 51 has a protrusion 53 on its top surface portion 51a that protrudes toward the second mounting portion 22 of the operating handle 20. This protrusion 53 is formed in the center position of the top surface portion 51a in the front-rear direction of the vehicle, and is formed in a rib shape along the width direction of the operating handle 20.

[0034] The buffer portion 51 also has a peripheral wall portion 54 extending in a direction opposite to the second mounting portion 22 of the operating handle 20. A part of the peripheral wall portion 54 has a locking portion 55 further extending in a direction opposite to the second mounting portion 22 of the operating handle 20.

[0035] Fig. 6 is a cross-sectional view taken along the horizontal direction of the door panel 1 at a mounting location of the handle device 100. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 6. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 6.

[0036] 6 to 8, the two buffer parts 51 provided on the second gasket 50 and protruding towards the second mounting part 22 of the operating handle 20 are disposed at contact points with the second mounting part 22 at the rear end of the operating handle 20 when the operating handle 20 is returned from the operating position to the initial position. These buffer parts 51 contact the second mounting part 22 of the operating handle 20 when the operating handle 20 is returned from the operating position to the initial position. This allows the buffer parts 51 to suppress the generation of hitting sounds that are generated when the operating handle 20 is returned from the operating position to the initial position.

[0037] The operating handle 20 has a recessed portion 57 formed at a position on the grip body 20A facing the buffer portion 51 of the second gasket 50, and when the operating handle 20 is returned to its initial position, the buffer portion 51 is accommodated in this recessed portion 57. The buffer portion 51 accommodated in the recessed portion 57 is adapted so that a protrusion 53 formed on a top surface portion 51a can abut against a bottom surface 57a of the recessed portion 57. In the second gasket 50, the claw portion 56 of the locking portion 55 locks the second support portion 14 of the handle base 10.

[0038] Next, a description will be given of the movement of the buffer portion 51 when it comes into contact with the second attachment portion 22 of the operating handle 20 which is returned from the operating position to the initial position. 9A and 9B are cross-sectional views taken along the vehicle front-rear direction of a contact point between the buffer portion 51 and the operating handle 20, illustrating how the buffer portion 51 of the second gasket 50 absorbs impact from the operating handle 20. FIG.

[0039] As shown in Fig. 9A, when the operating handle 20 is returned from the operating position to the initial position, the bottom surface 57a of the recessed portion 57 of the second mounting portion 22 comes into contact with the buffer portion 51 of the second gasket 50. Then, as shown in Fig. 9B, the buffer portion 51 of the second gasket 50 is deformed so as to be crushed by the abutting operating handle 20, and absorbs the impact from the operating handle 20. Here, the buffer portion 51 has a hollow portion 52 that is open on the side opposite to the second mounting portion 22 of the operating handle 20. Therefore, it is deformed so as to be smoothly crushed when the operating handle 20 comes into contact with it.

[0040] Moreover, the buffer part 51 has a protrusion 53 on its top surface 51a that protrudes towards the second attachment part 22 of the operating handle 20. Therefore, the impact from the operating handle 20 being returned to the initial position is received by the protrusion 53 of the buffer part 51, and then the top surface 51a of the buffer part 51, which has a hollow part 52 therein, is deformed so as to bend starting from the protrusion 53, and the impact received from the operating handle 20 is absorbed.

[0041] Thus, the second gasket 50 according to this embodiment and the handle device 100 including the same are provided with the buffer section 51 having the hollow section 52 that is open on the side opposite to the second mounting section 22 of the operating handle 20. Therefore, for example, compared to a case where the buffer section is solid, the buffer section 51 can better absorb the impact received from the operating handle 20 being returned from the operating position to the initial position. This makes it possible to sufficiently suppress the hitting sound generated when the operating handle 20 is returned to the initial position.

[0042] In particular, since the side portions of the hollow portion 52 of the buffer portion 51 are open, the buffer portion 51 deforms so as to be crushed more smoothly when the operating handle 20 abuts against it. Therefore, the shock received from the operating handle 20 can be absorbed more effectively, and the generation of hitting noise can be further suppressed.

[0043] Moreover, the buffer part 51 has a protrusion 53 that protrudes towards the second attachment part 22 of the operating handle 20. As a result, the impact from the operating handle 20 is received by the protrusion 53 of the buffer part 51, and then the top surface part 51a of the buffer part 51 is deformed so as to bend starting from the protrusion 53. Therefore, the impact from the operating handle 20 can be smoothly absorbed, and thus the hitting sound generated when the operating handle 20 comes into contact can be further suppressed.

[0044] It is preferable to adjust the shape and size of the protrusion 53 formed on the top surface 51a of the buffer unit 51 according to the impact received from the operating handle 20. In this way, by adjusting the shape and size of the protrusion 53, the flexibility of the top surface 51a of the buffer unit 51 can be easily adjusted. For example, by increasing the protruding dimension of the protrusion 53, the flexibility of the top surface 51a of the buffer unit 51 can be increased. It is also possible for the protrusion 53 to be formed in the shape of a long rib in the front-rear direction of the vehicle on the top surface 51a of the buffer unit 51, or to be formed in a dot shape in the center of the top surface 51a.

[0045] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.
