Description

TECHNICAL FIELD The present invention relates to a handle that covers the surface of a base material portion with a sheet-like covering member that holds an object to be held on a main body portion.

In recent years, there has been a demand to add additional functions to steering wheels of automobiles. For example, there is known a configuration in which a seat, which is a covering member provided with wiring that constitutes electric circuits such as a heater and a sensor unit, is set under the surface of the rim portion that is the grip portion of the steering wheel. Since the rim portion is generally formed in an annular shape or an arc shape, when covering the entire rim portion with a substantially rectangular sheet, a plurality of sheets are used by connecting the terminal portions to each other (for example, Patent Document 1 reference.).

JP 2019-73225 A (pages 6-13, Figures 1-7)

Due to the manufacturing process of the sheet, there is inevitably a non-set range where wiring cannot be arranged within a range of a predetermined distance from the end of the sheet. It is desirable to In addition, it is also required to prevent deterioration in the appearance of the portion where the terminal portions of the sheet are joined together.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a handle which is capable of setting a holding body of a covering member over a wide range of a base portion and which is excellent in appearance.

The handle according to claim 1 comprises a sheet-like covering member having a base material portion having a groove portion, a main body portion, and an object to be held held by the main body portion, the main body portion having a terminal end. One or more notches are formed in the portion, and the terminal portion is arranged on the surface of the base portion while being accommodated in the groove portion.

The handle according to claim 2 is the handle according to claim 1, wherein the held members are arranged in a zigzag pattern in a direction intersecting the groove at the end of the main body.

The handle according to claim 3 is the handle according to claim 2, wherein the notch is formed at the end of the main body at a position facing the zigzag concave portion of the object to be held.

In the handle according to claim 4, in the handle according to claim 2 or 3, a plurality of covering members are provided and accommodated in the groove with their terminal portions facing each other, and the terminal portions are covered with each other. The zigzag concave portion and the convex portion of the holder face each other.

According to the handle of claim 1, since the dimensional difference between the base end side and the tip end side of the terminal portion of the body portion that is dropped into the groove portion by the cut portion can be absorbed, the terminal portion is deep with respect to the groove portion, and can be reliably accommodated. Therefore, the object to be held can be arranged close to the edge of the groove, so that the object to be held of the covering member can be set in a wide range of the base material, and the end portion of the main body that is dropped into the groove can be arranged. Wrinkles and twists are less likely to occur in the position, and the appearance is excellent.

In the illustrated example, the grooves 34 are arranged at 2 o'clock, 4 o'clock, 8 o'clock, 10 o'clock, etc. when the steering wheel body 11 is viewed from the front as an analog clock. For example, the groove portion 34 may be formed at the same time when the resin layer 28 is molded using a molding die, or may be processed and formed after the resin layer 28 is molded.

The spoke covering portion 32 is continuous with the rim covering portion 31 and protrudes from the rim covering portion 31 toward the spoke core portion 25 side. In the present embodiment, the spoke covering portions 32 are formed at positions corresponding to, for example, the left and right spoke portions 17 (spoke core metal portions 25).

At least part of the resin layer 28 is covered with a covering member 36 that is a sheet-shaped functional component. The covering member 36 is also called an element, and is arranged from a position covering the rim core metal portion 26 of the resin layer 28, that is, the rim covering portion 31, to a position covering a part of the spoke core metal portion 25, that is, the spoke covering portion 32. be. A plurality of covering members 36 are provided. In this embodiment, a pair of covering members 36 are provided. In the illustrated example, each covering member 36 covers approximately half of the surface area of the resin layer 28 in the latitudinal direction (indicated by arrow L).

As shown in FIGS. 1(a), 1(b) and 3, the covering member 36 includes a sheet member (mat portion) 41 which is a body portion as a covering member main body formed in a sheet shape. . The sheet member 41 is formed in a long shape in a natural state. Terminal portions 41a and 41b, which are both ends in the longitudinal direction of the sheet member 41, are formed such that one is convex and the other is concave. In the present embodiment, one terminal portion 41a has a convex arc shape, and the other terminal portion 41b has a concave arc shape. Preferably, one terminal portion 41a of one covering member 36 and the other terminal portion 41b of the other covering member 36 are formed in an uneven shape that engages with each other. These terminal portions 41a and 41b are portions that are dropped into the groove portion 34 and accommodated.

Moreover, one or more notch portions 42a and 42b are formed in the terminal portions 41a and 41b of the sheet member 41, respectively. The cut portions 42a and 42b are cut into the terminal portions 41a and 41b along the longitudinal direction of the sheet member 41. As shown in FIG. The cut portions 42a and 42b are formed so as to gradually narrow inward from the outer edge of the sheet member 41. As shown in FIG. That is, the cut portions 42a and 42b are formed in a widening shape toward the outer edges of the terminal portions 41a and 41b of the sheet member 41. As shown in FIG. In the illustrated example, the notches 42a and 42b are formed in a triangular shape. In the present embodiment, a plurality of cut portions 42a and 42b are set apart from each other in the lateral direction of sheet member 41, respectively. In the end portions 41a and 41b of the sheet member 41, between the cut portions 42a and 42a and between the cut portions 42b and 42b adjacent to each other are dropped into the groove portion 34 and accommodated. is formed as In the present embodiment, the one cut portion 42a and the other cut portion 42b are offset from each other in the lateral direction of the sheet member 41. As shown in FIG.

Further, in the present embodiment, the seat member 41 includes a first covering portion 45 that covers the rim covering portion 31 (rim body portion 33) and a second covering portion 46 that partially covers the spoke covering portion 32. Ready for unity. The first covering portion 45 is formed in a substantially rectangular shape. The second covering portion 46 is formed so as to protrude from the long side of the first covering portion 45 .

Further, in the illustrated example, the sheet member 41 is formed with notch portions 48 on both side portions of the first covering portion 45 . These notch portions 48 are arranged in the middle portion of the sheet member 41 in the longitudinal direction. The portion of the sheet member 41 between these notch portions 48 forms an intermediate drop portion 49 that is dropped and accommodated in the groove portion 34 . In the present embodiment, the cutout portions 48 are formed on both long sides of the first covering portion 45, respectively.

A held body 51 is held on the sheet member 41 . The object to be held 51 is a conductive portion that is directly connected to a control circuit, a power supply, or the like (not shown), or indirectly connected via a power receiving portion or the like. In the present embodiment, when held body 51 is energized, covering member 36 functions as a heater unit configured to warm the fingers of the driver who grips rim portion 15 . Not limited to this, the covering member 36 may function as a sensor unit for detecting whether or not the driver grips the rim portion 15 (whether or not there is a grip) by energizing the held body 51 .

The object to be held 51 is set so as to occupy a predetermined planar area with respect to the sheet member 41 . The region in which the object to be held 51 is set is the operating range in which the function of the covering member 36 acts on the rim portion 15 . The object to be held 51 is positioned within a range A (shaded portion in FIG. 3) offset by a predetermined distance from the outer edge of the sheet member 41, and the outer edge side of the sheet member 41 beyond the range A is a non-set range B having a predetermined width. It has become.

The non-set range B is a portion where the held member 51 cannot be arranged which inevitably occurs as a placement limit of the held member 51 in the manufacturing process of the covering member 36 . In particular, the non-set range B occurs at the positions of the terminal portions 41a and 41b of the sheet member 41 at a predetermined distance from the outer edge of the sheet member 41, for example, a width of about 5 mm.

In the present embodiment, the objects to be held 51 are formed linearly and arranged in a unicursal pattern, that is, in a predetermined pattern without self-intersections. Further, the held members 51 are arranged in a zigzag pattern at positions facing the terminal portions 41a and 41b of the sheet member 41. As shown in FIG. In other words, the held body 51 is formed so that the concave portions 52 and the convex portions 53 are alternately arranged in the lateral direction of the sheet member 41 at the terminal portions 41a and 41b. Preferably, the notched portions 42a and 42b of the sheet member 41 are located at positions facing the recessed portion 52 so as to face each other.

Also, in the illustrated example, in the area A, the density of arrangement of the objects to be held 51 at the position of the intermediate drop portion 49 of the sheet member 41 is coarser than the density of arrangement at other positions. there is For example, the object to be held 51 is arranged in a straight line or the like that intersects with the intermediate drop portion 49 at the position of the intermediate drop portion 49 .

Further, the object to be held 51 is electrically connected to a control circuit, a power supply, etc. via a terminal portion 56 via an extension portion 55 extending from the second covering portion 46 of the sheet member 41 . In the present embodiment, the extending portions 55 of the pair of covering members 36 are connected to each other, and a wiring harness-like connection terminal portion 56 is led out from the extending portion 55 .

The object to be held 51 may be formed of a wire separate from the sheet member 41 and fixed to the sheet member 41, or may be integrally formed on the surface of the sheet member 41 by printing. .

The covering member 36 is adhered and fixed to the resin layer 28 (rim body portion 33) with an adhesive. The adhesive is applied to at least one of the coating member 36 and the resin layer 28 (rim body portion 33). The adhesive may be set in advance on the back side of the sheet member 41 of the covering member 36, that is, on the rim main body portion 33 side, or may be applied when the covering member 36 is attached to the rim main body portion 33. may

Further, the surface of the covering member 36 is covered with a skin portion 58 shown in FIG. 1(b). The skin portion 58 is a portion that is directly gripped by the driver (passenger) and is a decorative portion of the steering wheel 10 . The skin portion 58 is formed in a sheet shape, for example, from leather such as natural leather or synthetic leather, synthetic resin, or the like. The skin portion 58 is attached to the rim main body portion 33 while covering the covering member 36 . For example, the skin portion 58 is arranged so as to cover the covering member 36 and continuously cover the entire surface of the rim main body portion 33 . In the present embodiment, the outer skin portion 58 is fixed by dropping the terminal portions 58a and 58b into the positions of the groove portions 34, respectively, and is fixed. It constitutes a design portion 59 having a shape. In the illustrated example, a plurality of skin portions 58, for example, a pair are set. Not limited to this, the skin portion 58 may be integrally molded with a synthetic resin such as urethane so as to cover the surface of the resin layer 28 including the groove portions 34 .

When manufacturing the steering wheel 10, first, the preformed core metal 20 is set in a mold, and then one half mold and the other half mold are matched (closed) to form the mold. Synthetic resin raw materials are stirred and mixed into the cavity and injected into the cavity of the mold. As a result, the synthetic resin raw material reacts with foaming to form polyurethane and flows toward the flow end.

Next, the first intermediate formed by covering the rim core metal portion 26 with the resin layer 28 in the cavity is demolded from the mold by opening one half mold and the other half mold, and is freed from burrs and the like. to cut.

Further, a separately formed coating member 36 is wound around the surface of the resin layer 28 (rim body portion 33) of the first intermediate. At this time, the terminal portion 41a of the sheet member 41 of one covering member 36 and the terminal portion 41b of the sheet member 41 of the other covering member 36 are made to face each other, and the dropping portions 43a and 43b are dropped into the groove portion 34 and accommodated. , the intermediate drop portion 49 of each covering member 36 is dropped into the groove portion 34 and accommodated.

At this time, since the groove 34 is formed in an arc shape or an annular shape in the meridian direction of the resin layer 28 (rim main body 33), the opening edge side and the bottom side of the groove 34 have different circumferential lengths. Therefore, when the dropped portions 43a and 43b of the terminal portions 41a and 41b are dropped into the groove portion 34 as they are, the terminal portions 41a and 41b (dropped portions) are caused by the difference in circumferential length of the groove portion 34 between the proximal end side and the distal end side of the dropped portions 43a and 43b. The portions 43a and 43b) cannot be inserted sufficiently deep into the groove portion 34, and the terminal portions 41a and 41b are excessive on the tip side, resulting in wrinkles and twists. Therefore, in the present embodiment, the terminal portion 41a of the sheet member 41 of one covering member 36 and the terminal portion 41b of the sheet member 41 of the other covering member 36 are arranged as shown in FIGS. , the notch portions 42a and 42b absorb the dimensional difference between the base end side and the tip end side of the drop portions 43a and 43b, and the drop portions 43a and 43b of the terminal portions 41a and 41b go deep into the groove portion 34 to prevent wrinkles and twists. It can be pushed in neatly without generating

In this state, the held members 51 of each covering member 36 are arranged in a zigzag pattern in a direction intersecting the groove 34 at the end portions 41a and 41b of the sheet member 41. (aperture edge). In addition, the zigzag concave portion 52 of the held body 51 of one covering member 36 faces the zigzag convex portion 53 of the held body 51 of the other opposing covering member 36 . That is, the held bodies 51 of the one covering member 36 and the held bodies 51 of the other covering member 36 are alternately arranged in the latitudinal direction of the resin layer 28 (the rim body portion 33), that is, the one covering member The concave portion 52 of the held body 51 of the 36 and the convex portion 53 of the held body 51 of the other covering member 36 are engaged with each other in the latitudinal direction of the resin layer 28 (rim main body portion 33), and face each other in the groove portion 34. located in close proximity to

Thereafter, each covering member 36 is attached with an adhesive and fixed to the surface of the resin layer 28 (rim body portion 33) of the first intermediate. Furthermore, the covering member 36 is covered with the skin portion 58 . At this time, the surface sides of the terminal portion 58a of one skin portion 58 and the terminal portion 58b of the other skin portion 58 are brought into contact with each other, and the design portion 59 is formed by dropping them into the groove portion 34 and fixing them.

The steering wheel main body 11 has the functional parts of the covering member 36 electrically connected to the control circuit, and the steering wheel 10 is completed by attaching the module 12, the cover body, and the like.

As described above, in the present embodiment, one or more notch portions 42a and 42b are formed in the end portions 41a and 41b of the sheet member 41 of the covering member 36 that holds the object to be held 51, and the end portions 41a and 41b are formed. By attaching the covering member 36 to the surface of the resin layer 28 while being accommodated in the groove portion 34, the sheet members 41, 41 dropped into the groove portion 34 by the cut portions 42a, 42b are dropped into the terminal portions 41a, 41b of the sheet members 41a, 41b. Since the dimensional difference between the proximal end side and the distal end side of 43b can be absorbed by the cut portions 42a and 42b, the terminal portions 41a and 41b can be stored deeply in the groove portion 34 and securely. In particular, even in a configuration in which the terminal portion 41a of one of the paired covering members 36 and the terminal portion 41b of the other covering member 36 are opposed to each other and housed in the groove portion 34, the terminals The portions 41a and 41b are less likely to interfere with each other's insertion into the groove portion 34 due to wrinkles and twists of surplus portions caused by the dimensional difference between the base end side and the tip end side of the drop portions 43a and 43b.

Therefore, since the object to be held 51 can be arranged close to the edge (near the edge of the opening) of the groove 34, the object to be held 51 of the covering member 36 can be set in the widest possible range of the resin layer 28. , Wrinkles and twists are less likely to occur at the positions of the terminal portions 41a and 41b of the sheet member 41 dropped into the groove portion 34, and large unevenness is less likely to occur at the position of the groove portion 34 (design portion 59) even when covered with the skin portion 58. and has an excellent appearance. Therefore, the function of the held member 51 can be exerted evenly over the entire rim portion 15 of the steering wheel 10 . For example, when the covering member 36 is used as a heater unit, the holding member 51 can heat the entire rim portion 15 substantially uniformly, thereby improving the performance.

For example, in the case of the example shown in FIG. 1B, the distance between the held body 51 of the terminal portion 41a of one covering member 36 and the held body 51 of the terminal portion 41b of the other covering member 36 is , which is about the same as the width of the groove 34 (about 5.6 mm). Therefore, since this distance is set to about half the width of one finger of a general human, even if the covering member 36 is used as a heater unit, the position near the groove 34 will not be warmed. Hateful.

Moreover, as compared with the conventional example, no additional parts are required, and the quality and appearance can be improved at a low cost.

By arranging the object to be held 51 in a zigzag manner in a direction crossing the groove portion 34 at the terminal portions 41a and 41b of the sheet member 41, the terminal portions 41a and 41b of the sheet member 41 accommodated in the groove portion 34 are also supported. The function of the holder 51 can be effectively exhibited in the zigzag stroke range. For example, when the covering member 36 is used as a heater unit, the object to be held 51 can heat the zigzag stroke range of the concave portion 52 and the convex portion 53 at the edge position of the groove portion 34, thereby improving the performance. .

By forming the notch portions 42a and 42b at positions facing the zigzag concave portions 52 of the held body 51 at the end portions 41a and 41b of the sheet member 41, the sheet member 41 in which the held body 51 cannot be set is eliminated. By making effective use of the non-set range B of the terminal portions 41a and 41b, the notch portions 42a and 42b can be formed without greatly moving the held body 51 away from the terminal portions 41a and 41b of the sheet member 41. FIG.

Further, the terminal portions 41a, 41b and the terminal portions 41b, 41a of the plurality of covering members 36 are accommodated in the groove portion 34 in such a manner that the terminal portions 41a, 41b of one covering member 36 and the terminal portions 41b, 41b of the other covering member 36 face each other. By facing the zigzag concave portion 52 and the convex portion 53 of the object to be held 51 with the end portions 41b and 41a of the covering member 36, one coating is Since the object to be held 51 of the member 36 and the object to be held 51 of the other covering member 36 are not greatly separated from each other at the positions of the terminal portions 41a and 41b and are kept at substantially constant intervals, the covering member 51 is held at a position around the groove portion 34. It becomes difficult for the function of the held body 51 of 36 to be biased or uneven.

In one embodiment, it is also possible to use a magnet (massage magnet), a decorative member, etc. other than the circuit section as the object to be held.

Further, the position and number of the grooves 34 can be arbitrarily set according to the design of the steering wheel 10 and the like.

Furthermore, the steering wheel 10 is not limited to the structure having three spoke portions 17, and may have a structure having two spoke portions 17, or four or more spoke portions 17, or the like.

The steering wheel 10 can be used not only for vehicles such as automobiles, but also as a steering wheel for any vehicle.

INDUSTRIAL APPLICABILITY The present invention can be suitably used, for example, as a steering element used in a steering wheel of an automobile, a steering wheel provided with the steering element, and a manufacturing method thereof.
