Description

車輛用方向盤套Vehicle steering wheel cover

本發明係有關一種安裝在車輛用方向盤來使用的方向盤套。The invention relates to a steering wheel cover installed on a steering wheel of a vehicle for use.

在車輛之標準配備的方向盤中，有些方向盤徑較小，會有駕駛者反應像這種直徑較小的方向盤不易抓握，不易於駕駛。此外，一般標準方向盤是以黑色為基調，所以也有駕駛者反應單調且缺乏設計性。Among the standard steering wheels of the vehicle, some steering wheels have a small diameter, and the driver will respond that such a small diameter steering wheel is not easy to grasp and not easy to drive. In addition, the general standard steering wheel is based on black, so there are also drivers who respond monotonously and lack design.

為了消除這種駕駛者的反應，一直以來即提供一種安裝在方向盤來使用的車輛用方向盤套(參照非專利文獻1)。In order to eliminate such driver's reaction, a steering wheel cover for a vehicle that is attached to the steering wheel for use has been provided (see Non-Patent Document 1).

針對以往之車輛用方向盤套的構造來簡單說明的話，車輛用方向盤套係為從前面看是呈環狀的中空構件，在其內周面形成有遍佈其全周的切開部。因為切開部僅被切開極小的寬度，所以，與車輛用方向盤套之周方向正交之方向剖面形狀呈略C字狀，藉由將方向盤嵌入到其內部空間的方向盤收容部內，即完成將車輛用方向盤套安裝到方向盤的作業。To briefly describe the structure of a conventional steering wheel cover for a vehicle, the steering wheel cover for a vehicle is a hollow member that is ring-shaped when viewed from the front, and a cutout portion is formed on the inner peripheral surface of the cover over the entire circumference. Because the cut part is only cut with a very small width, the cross-sectional shape in the direction orthogonal to the circumferential direction of the steering wheel cover for the vehicle is slightly C-shaped. By inserting the steering wheel into the steering wheel housing part of the inner space, the vehicle is completed Use the steering wheel cover to install to the steering wheel.

只要如此將車輛用方向盤套安裝到方向盤，即可使方向盤徑變大，故可使方向盤操作或駕駛變得容易。此外，藉由在車輛用方向盤套的表面加以裝飾，即可大幅度提高設計性。 [先前技術文獻] [非專利文獻]As long as the vehicle steering wheel cover is attached to the steering wheel in this way, the diameter of the steering wheel can be enlarged, so that the steering wheel can be operated or driven easily. In addition, by decorating the surface of the vehicle steering wheel cover, the design can be greatly improved. [Prior Technical Literature] [Non-Patent Literature]

[發明所欲解決之課題][The problem to be solved by the invention]

這種以往的車輛用方向盤套，在安全對策上會做得比較緊，以避免在行進間因急轉方向盤等而導致移位或脫離。具體而言，車輛用方向盤套的環內徑(也就是接觸到方向盤外面之那一面的內尺寸)，是設定為大致相同(或較小)於方向盤的直徑(外徑)，並且，車輛用方向盤套本身也是由不易延展的材質所製成。Such conventional steering wheel covers for vehicles will be tighter in terms of safety measures to avoid shifting or detaching due to sudden steering wheel turning during travel. Specifically, the inner diameter of the ring of the steering wheel cover for vehicles (that is, the inner dimension of the surface that contacts the outer surface of the steering wheel) is set to be approximately the same (or smaller) than the diameter (outer diameter) of the steering wheel, and for vehicles The steering wheel cover itself is also made of a material that is not easy to stretch.

因此，將車輛用方向盤套安裝到方向盤的安裝作業，即如下述般，是為極辛苦的勞力。也就是說，在把車輛用方向盤套安裝到方向盤時，在車輛用方向盤套的上端部分打開切開部，將此部分覆蓋方向盤的上端部分，沿著方向盤的外周一邊打開切開部，一邊將方向盤慢慢裝進方向盤收容部內。但是，因為車輛用方向盤套的環內徑和方向盤的外徑大致相同(或稍小)，所以，在從到達方向盤之最大外徑的未達最大徑的位置，一直到方向盤的最大外徑的位置為止安裝方向盤套時，因為安裝部分之方向盤的外徑以及方向盤套的環內徑變成大致相同，並且，構成車輛用方向盤套之切開部的裏側的開口緣部彎折，用力接觸到方向盤(特別是從方向盤之未達最大徑的位置到最大徑位置的範圍)的表面，甚至，車輛用方向盤套本身也難以伸展，所以無法進一步安裝進去(參照圖7)。Therefore, the installation work of attaching the steering wheel cover for the vehicle to the steering wheel, as described below, is extremely laborious. In other words, when attaching the vehicle steering wheel cover to the steering wheel, open the cut section at the upper end of the vehicle steering wheel cover to cover the upper end of the steering wheel, and open the cut section along the outer circumference of the steering wheel while slowing the steering wheel. Slowly install it into the steering wheel housing. However, because the inner diameter of the steering wheel cover for a vehicle is approximately the same (or slightly smaller) than the outer diameter of the steering wheel, the position from the position that reaches the maximum outer diameter of the steering wheel and does not reach the maximum diameter until the maximum outer diameter of the steering wheel When the steering wheel cover is installed up to the position, the outer diameter of the steering wheel of the mounting part and the ring inner diameter of the steering wheel cover become approximately the same, and the inner opening edge of the cut part of the steering wheel cover for the vehicle is bent and comes into contact with the steering wheel ( In particular, the surface of the steering wheel from the position below the maximum diameter position to the maximum diameter position), even the vehicle steering wheel cover itself is difficult to stretch, so it cannot be further installed (refer to Fig. 7).

因此，強拉不易伸展的方向盤套，一邊將方向盤套的環內徑拉大，一邊將方向盤收容部的開口緣部(也就是構成未達一半的位置的上記切開部之裏側的開口緣部)向外側捲起，一點一點將車輛用方向盤套安裝到方向盤，但因為車輛用方向盤套是由不易伸展的材質所作成，所以將上述環內徑拉大，或將開口緣部捲起的作業是非常不容易。Therefore, for a steering wheel cover that is not easily stretched by strong pulling, while the inner diameter of the steering wheel cover is enlarged, the opening edge of the steering wheel accommodating part (that is, the opening edge of the inner side of the upper mark notch that constitutes less than half of the position) Roll up to the outside and install the vehicle steering wheel cover to the steering wheel bit by bit. However, because the vehicle steering wheel cover is made of a material that is not easy to stretch, the inner diameter of the ring is enlarged or the opening edge is rolled up The homework is not easy.

所以，特別是力氣較小的女性經常無法獨自完成安裝作業，或不得不利用付費的安裝服務等，對於使用方向盤套的障礙較大，這對於車輛用方向盤套的製造業者來說，安裝的難度變成獲得新客戶的最大阻礙。Therefore, women with less energy often cannot complete the installation work alone, or have to use paid installation services, etc. The obstacles to the use of steering wheel covers are greater. This is difficult for manufacturers of vehicle steering wheel covers to install. Become the biggest obstacle to gaining new customers.

本發明鑑於以往的問題點，其目的即為提供一種即使是女性也能簡單地安裝，並且在安裝後不易移位且不易脫落的車輛用方向盤套。 [用以解決課題之手段]In view of the problems of the past, the purpose of the present invention is to provide a steering wheel cover for a vehicle that can be easily installed even by women, and is not easily displaced and does not easily fall off after installation. [Means to solve the problem]

於請求項1所記載的發明係為安裝在車輛之方向盤H的車輛用方向盤套10，其特徵為： 車輛用方向盤套10係為從前面看略呈環狀的中空構件，在其內周面形成有遍佈其全周的切開部12，該切開部12係連通作為車輛用方向盤套10之內部空間的方向盤收容部14以及外部，且用來***取出方向盤H， 在面向前述切開部12的一對開口緣部16a、16b中的其中一個開口緣部16a，形成有切除部18，該切除部18是起端S位在超過3點鐘方向的位置，通過6點鐘方向，一直到其末端T到達接近9點鐘方向的範圍予以切除所形成， 前述切除部18的起端部以及末端部，係作為傾斜邊20a、20b所構成。The invention described in claim 1 is a vehicle steering wheel cover 10 mounted on a steering wheel H of a vehicle, and is characterized by: The steering wheel cover 10 for a vehicle is a hollow member having a slightly annular shape when viewed from the front. A cut portion 12 is formed on the inner peripheral surface of the steering wheel cover 10 throughout the entire circumference. The cut portion 12 communicates with the inner space of the steering wheel cover 10 for the vehicle. The steering wheel accommodating part 14 and the outside, and used to insert and remove the steering wheel H, On one of the opening edges 16a, 16b of the pair of opening edges 16a, 16b facing the incision portion 12, a cutout 18 is formed. It is formed by cutting off in the direction of o'clock until its end T reaches the range close to the direction of 9 o'clock, The beginning and end portions of the aforementioned cut-out portion 18 are constituted as inclined sides 20a and 20b.

於請求項2所記載的的發明，其特徵為：當從背面來看車輛用方向盤套10時，由水平線X以及連接線Y所成的角θ係在5°～12°的範圍，該水平線X係通過車輛用方向盤套10的環中心P，將車輛用方向盤套10畫分成上下；該連接線Y係連接述車輛用方向盤套10的環中心P與起端S(末端T)。The invention described in claim 2 is characterized in that when the vehicle steering wheel cover 10 is viewed from the back, the angle θ formed by the horizontal line X and the connecting line Y is in the range of 5° to 12°, and the horizontal line The X system divides the vehicle steering wheel cover 10 into upper and lower parts through the ring center P of the vehicle steering wheel cover 10; the connecting line Y connects the ring center P of the vehicle steering wheel cover 10 and the starting end S (end T).

於請求項3所記載的發明，其特徵為：在與車輛用方向盤套10之周方向正交的方向的剖面，由連接線M以及連接線N所成的角β，係在40°～55°的範圍，該連接線M係連接車輛用方向盤套10的管中心Q、與被夾在切除部18的傾斜邊20a、20b之間的中央部分20c；該連接線N係連接前述管中心Q、與切除部18形成前的開口緣部16a’。 [發明效果]The invention described in claim 3 is characterized in that the angle β formed by the connecting line M and the connecting line N in a cross section in a direction orthogonal to the circumferential direction of the steering wheel cover 10 for a vehicle is between 40° and 55 ° range, the connecting line M connects the tube center Q of the vehicle steering wheel cover 10 and the central portion 20c sandwiched between the inclined sides 20a, 20b of the cutout 18; the connecting line N connects the aforementioned tube center Q , Form the opening edge 16a' before the cutout 18. [Effects of the invention]

根據這些發明，在把車輛用方向盤套安裝到方向盤時，藉由在超出方向盤之最大外徑的範圍設置切除部，即能用較小的力氣來完成最難安裝的部分(從未達方向盤之最大外徑的位置一直到方向盤之最大外徑的位置為止的範圍)，並且，藉由在切除部的兩端部形成一直到達切除部之中央部分的傾斜邊，即可使最難安裝之部分的傾斜邊部分變成較寬鬆，和以往品相較，可輕易捲起開口緣部，即使是力氣小的女性也能輕易地進行將車輛用方向盤套安裝到方向盤的安裝作業。此外，本發明的車輛用方向盤套，係可藉由將開口緣部的一側(裏側)局部切除所形成，所以，即使和以往的車輛用方向盤套相較，其與方向盤的密貼性或目視上並沒有太大的差異，能達成不遜於以往品的車輛用方向盤套。 再者，因為切除部是形成在從超過3點鐘方向一直到接近9點鐘方向的範圍，所以，在包覆方向盤之最大外徑部分的部分沒有形成切除部，在操作時即使施以較大的力量，方向盤套也不會從方向盤脫離。According to these inventions, when installing the steering wheel cover for a vehicle to the steering wheel, by providing a cut-out part beyond the maximum outer diameter of the steering wheel, the most difficult part of the installation can be completed with less effort (the part that has never reached the steering wheel). The range from the position of the largest outer diameter to the position of the largest outer diameter of the steering wheel), and the most difficult part to install can be made by forming inclined edges on both ends of the cutout that reach the center of the cutout. The sloping side of the car is looser. Compared with the conventional product, the opening edge can be easily rolled up. Even women with weaker strength can easily install the steering wheel cover for the vehicle to the steering wheel. In addition, the vehicle steering wheel cover of the present invention can be formed by partially cutting off one side (inside) of the opening edge. Therefore, even if compared with the conventional vehicle steering wheel cover, its adhesion to the steering wheel is better. There is not much visual difference, and a steering wheel cover for vehicles that is not inferior to conventional products can be achieved. Furthermore, because the cutout is formed in the range from more than 3 o'clock to close to 9 o'clock, no cutout is formed in the part covering the largest outer diameter part of the steering wheel, even if it is operated. With great power, the steering wheel cover will not detach from the steering wheel.

根據圖式說明本發明如下。圖1係為本發明之車輛用方向盤套10的前視圖，圖2為其後視圖，圖3為圖2之A-A’剖面圖。The present invention is explained based on the drawings as follows. Fig. 1 is a front view of a steering wheel cover 10 for a vehicle of the present invention, Fig. 2 is a rear view thereof, and Fig. 3 is a cross-sectional view of A-A' in Fig. 2.

如這些圖面所示般，本發明的車輛用方向盤套(以下簡稱為「方向盤套」。)10係為從前面看呈環狀的中空構件，在其內周面(方向盤套10的中心側那一面)形成遍佈其全周，且具有切口寬度的切開部12。藉由如此，作為方向盤套10之內部空間的方向盤收容部14，透過切開部12與外部連通，與方向盤套10之周方向正交的方向的剖面形狀，即呈略C字狀(參照圖3)。As shown in these drawings, the vehicle steering wheel cover (hereinafter referred to as "steering wheel cover") 10 of the present invention is a hollow member having a ring shape when viewed from the front. On that side), a cut portion 12 having a cut width is formed all over the entire circumference. In this way, the steering wheel accommodating portion 14, which is the internal space of the steering wheel cover 10, communicates with the outside through the cut portion 12, and has a cross-sectional shape in a direction orthogonal to the circumferential direction of the steering wheel cover 10, that is, an abbreviated C-shape (see FIG. 3). ).

從安裝到方向盤的簡易度、或是在安裝後，駕駛不易看到切開部12等觀點來看的話，切開部12的切口寬度係被設定在以下的範圍。也就是說，在與方向盤套10之周方向正交之方向的剖面，由連接線K與連接線L所成的角度α，係設定在30°±5°的範圍(參照圖3的右上圖)，該連接線K係連接其中一側的開口緣部16a、與管中心Q；該連接線L係連接另一側開口緣部16b、與管中心Q。From the viewpoints of ease of attachment to the steering wheel, or difficulty in seeing the cut portion 12 after installation, the cut width of the cut portion 12 is set to the following range. That is, in the cross section in the direction orthogonal to the circumferential direction of the steering wheel cover 10, the angle α formed by the connecting line K and the connecting line L is set in the range of 30°±5° (refer to the upper right diagram of FIG. 3 ), the connecting line K connects the opening edge 16a on one side with the tube center Q; the connecting line L connects the opening edge 16b on the other side with the tube center Q.

方向盤套10的環內徑(從前面來看方向盤套10時，彼此對向之方向盤套10的內側面10a、10a之間的距離。參照圖1，圖3)R，係被設定為大致相等或稍小於方向盤的外徑。The ring inner diameter of the steering wheel cover 10 (when the steering wheel cover 10 is viewed from the front, the distance between the inner sides 10a, 10a of the steering wheel cover 10 facing each other. Refer to Figure 1, Figure 3) R, which is set to be approximately equal Or slightly smaller than the outer diameter of the steering wheel.

在面向切開部12的一對開口緣部16a、16b中，於其中一側的開口緣部16a形成有切除部18(參照圖2～圖4)。切除部18係為為了容易將方向盤套10安裝到方向盤所設的切除部分，如圖2所示般，在將形成有切除部18那一側的面朝向外側時，切除部18的起端S位在超過3點鐘方向的位置(亦即，超過通過環中心P的水平線X、與方向盤套10之外形線交叉的位置)，通過6點鐘方向，一直到末端T到達接近9點鐘方向的位置(亦即，接近通過環中心P的水平線X、與方向盤套10之相反側的外形線交叉的位置)。再者，在本實施例中，形成有切除部18之那一側的面係為方向盤套10的裏面側，沒有形成切除部18之相反側的那一面為表面側。In a pair of opening edge portions 16a, 16b facing the cut portion 12, a cutout portion 18 is formed on one of the opening edge portions 16a (see FIGS. 2 to 4). The cut-out portion 18 is a cut-out portion provided for easy installation of the steering wheel cover 10 to the steering wheel. As shown in FIG. At a position beyond 3 o'clock (that is, beyond the horizontal line X passing through the center P of the ring and crossing the outer shape line of the steering wheel cover 10), passing through the 6 o'clock direction, until the end T reaches the direction close to 9 o'clock (That is, close to the position where the horizontal line X passing through the ring center P intersects the outline line on the opposite side of the steering wheel cover 10). Furthermore, in this embodiment, the surface on the side where the cutout 18 is formed is the back side of the steering wheel cover 10, and the surface on the opposite side where the cutout 18 is not formed is the front side.

在使方向盤套10的裏面側朝向外側的狀態下(參照圖2)，切除部18的起端S是被設定位在：由水平線X、與連接線Y所成的角(俯角)θ，分別在5°～12°的範圍(在本實施例中係設定為9°)，該水平線X是通過方向盤套10的環中心P；該連接線Y是連接環中心P與起端S(末端T)。In the state where the inner side of the steering wheel cover 10 faces the outside (refer to FIG. 2), the starting end S of the cutout 18 is set at the angle (depression angle) θ formed by the horizontal line X and the connecting line Y, respectively In the range of 5° to 12° (in this embodiment, it is set to 9°), the horizontal line X passes through the ring center P of the steering wheel cover 10; the connecting line Y connects the ring center P and the starting end S (end T ).

前述起端S以及末端T的位置，係以滿足將方向盤套10安裝到方向盤H時的簡易度、以及在安裝後不易脫落的這2個完全相反的功能的觀點來加以設定。也就是說，當前述俯角θ小於5°時，切除部18的形成範圍過大，在安裝到方向盤後，有容易從方向盤套10脫落的問題。另一方面，當前述俯角θ大於12°時，切除部18的形成範圍過小，又會有極度不易將方向盤套安裝到方向盤的問題發生(此點後述)。The positions of the starting end S and the end T are set to satisfy the two completely opposite functions of ease when attaching the steering wheel cover 10 to the steering wheel H and not easy to fall off after attaching. That is, when the aforementioned depression angle θ is less than 5°, the formation range of the cut-out portion 18 is too large, and there is a problem that it is easy to fall off from the steering wheel cover 10 after being installed on the steering wheel. On the other hand, when the aforementioned depression angle θ is greater than 12°, the formation range of the cutout portion 18 is too small, and it is extremely difficult to install the steering wheel cover on the steering wheel (this point will be described later).

切除部18的起端部以及末端部，係作為傾斜邊20a、20b，被夾在此左右一對傾斜邊20a、20b之間的直線部分，即為中央部分20c(參照圖2及圖4)。The start and end of the cutout 18 are the inclined sides 20a, 20b, and the straight part sandwiched between the left and right pair of inclined sides 20a, 20b is the central part 20c (refer to Figures 2 and 4) .

切除部18之中央部分20c的位置(切除部18的切除寬度)，係被設定如下。亦即，在與方向盤套10之周方向正交的方向的剖面(參照圖3的左下部)，由連接直線M、以及連接直線N所成的角(切除角)β係被設定在40°～55°的範圍，尤以設在位於45°～50°的範圍為佳(在本實施例中係設為50°)，該連接直線M係連接切除部18形成前的開口緣部16a’、與管中心Q；該連接直線N係連接管中心Q、與中央部分20c。The position of the central portion 20c of the cutout 18 (the cutout width of the cutout 18) is set as follows. That is, in the cross section in the direction orthogonal to the circumferential direction of the steering wheel cover 10 (refer to the lower left of FIG. 3), the angle (cut-off angle) β formed by the connecting straight line M and the connecting straight line N is set to 40° The range of -55° is particularly preferably set in the range of 45°-50° (in this embodiment, it is set to 50°), and the connecting straight line M is connected to the opening edge 16a' before the cutout 18 is formed. , And the tube center Q; the connecting straight line N connects the tube center Q and the central part 20c.

當切除角β小於40°時，會有安裝作業不易進行的問題，而當切除角β大於55°時，方向盤套10對於方向盤的密合性下降，又會有在安裝到方向盤後容易從方向盤脫落的問題發生。When the cut-off angle β is less than 40°, there will be a problem that the installation work is not easy, and when the cut-off angle β is greater than 55°, the adhesion of the steering wheel cover 10 to the steering wheel will decrease, and it will be easy to remove from the steering wheel after being installed on the steering wheel. The problem of falling off occurs.

方向盤套10可以是由單一素材所形成，但如果將多種素材加以組合的話，則可以構成同時具有彈性、緩衝性、保形性、止滑性、觸感佳、以及美觀等多種功能者。在本實施例中，如圖5所示般，係為由基座構件22、緩衝層24、以及化妝層26所形成的三層構造。The steering wheel cover 10 may be formed of a single material, but if multiple materials are combined, it can be configured to have multiple functions such as elasticity, cushioning, shape retention, anti-slip, good tactility, and aesthetics at the same time. In this embodiment, as shown in FIG. 5, it has a three-layer structure formed by a base member 22, a cushion layer 24, and a makeup layer 26.

基座構件22係為作為方向盤套10之基礎的部分，謀求不易因為經過長年變化等所引起的變形・鬆弛(保形性)、以及在方向盤套10使用時，在方向盤與方向盤套之間不易產生滑動(止滑性)的功能。由此觀點來看，作為基座構件22的材質，例如可使用具有像彈性體的橡膠彈性，且摩擦係數較大者(在本實施例中，係使用三元乙丙橡膠(EPDM))。The base member 22 is a part of the foundation of the steering wheel cover 10, and it is not easy to deform and slack (shape retention) caused by long-term changes, and it is difficult to be between the steering wheel and the steering wheel cover when the steering wheel cover 10 is used. The function of generating slip (anti-slip). From this point of view, as the material of the base member 22, for example, a rubber elasticity like an elastic body and a relatively large friction coefficient can be used (in this embodiment, ethylene propylene diene rubber (EPDM) is used).

緩衝層24係為給予方向盤套10緩衝性的部分，其材質在本實施例中，係使用發泡性的聚胺甲酸乙酯。The cushion layer 24 is a part that provides cushioning to the steering wheel cover 10, and its material is foamable polyurethane in this embodiment.

化妝層26係為提高方向盤套10之美感性的部分，其材質在本實施例中係使用氯乙烯，在其表面，例如是施加會讓人以為是真皮的表紋加工，或是花朵圖案的印刷等。The cosmetic layer 26 is a part that enhances the aesthetics of the steering wheel cover 10. Its material is vinyl chloride in this embodiment. For example, the surface of the cosmetic layer 26 is processed to make people think it is genuine leather or printed with flower patterns. Wait.

在構成前述多層構造(在本實施例中為三層構造)的方向盤套10時，係依序在基座構件22上疊上緩衝層24與化妝層26，將緩衝層24與化妝層26的端部折入基座構件22的裏側，將邊緣部縫合，使各構件縫接在一起。When the steering wheel cover 10 of the aforementioned multilayer structure (three-layer structure in this embodiment) is constructed, the cushion layer 24 and the makeup layer 26 are sequentially stacked on the base member 22, and the cushion layer 24 and the makeup layer 26 The ends are folded into the inner side of the base member 22, and the edges are sewn together, so that the components are sewn together.

在把如前述般構成的方向盤套10安裝到方向盤H時，使方向盤套10的表面(沒有形成切除部18的那一側面)朝向自己，調整方向盤套10的角度以使切除部18位在方向盤H的下側一半的位置。在此狀態下，將方向盤套10的頂點對齊方向盤H的頂點，從上方覆蓋，即可將方向盤H的頂點裝進方向盤收容部14內。When attaching the steering wheel cover 10 constructed as described above to the steering wheel H, make the surface of the steering wheel cover 10 (the side where the cutout portion 18 is not formed) face yourself, and adjust the angle of the steering wheel cover 10 so that the cutout portion 18 is positioned on the steering wheel. The position of the lower half of H. In this state, by aligning the apex of the steering wheel cover 10 with the apex of the steering wheel H and covering it from above, the apex of the steering wheel H can be installed in the steering wheel accommodating portion 14.

用單手握緊住被方向盤H之頂點包覆的方向盤套10(參照圖6)，用另一手一邊交互將方向盤套10的兩側拉向身體側，一邊捲起開口緣部16a、16b，即可從方向盤H的上方朝向下方一點一點地加以包覆 (參照圖7)。Grasp the steering wheel cover 10 covered by the apex of the steering wheel H with one hand (refer to FIG. 6), and use the other hand to alternately pull both sides of the steering wheel cover 10 to the side of the body, while rolling up the opening edges 16a, 16b, That is, it can be covered little by little from above the steering wheel H toward the bottom (refer to FIG. 7).

在此，說明方向盤H與方向盤套10的關係。在把方向盤套10安裝到方向盤H時，一直到未達方向盤H之最大外徑Hm的位置為止，在方向盤H與方向盤套10之方向盤收容部14之間還很寬鬆(具有大空隙)，所以可順利地嵌入。Here, the relationship between the steering wheel H and the steering wheel cover 10 will be described. When the steering wheel cover 10 is installed on the steering wheel H, until the position of the maximum outer diameter Hm of the steering wheel H is not reached, the steering wheel H and the steering wheel accommodating portion 14 of the steering wheel cover 10 are still loose (having a large gap), so Can be embedded smoothly.

當安裝作業從未達方向盤H之最大外徑Hm的位置進行到方向盤H之最大外徑Hm的位置範圍(圖8的B所示的部分)時，在安裝部分的方向盤H與方向盤套10的方向盤收容部14之間的空隙變得極為狹窄。此外，因為方向盤套10本身是由不易伸展的材質所製，所以，方向盤套10之面向切開部12的開口緣部16a、16b會朝向內側彎折，該彎折部分會緊緊碰到方向盤H的表面，所以在把方向盤套10安裝到方向盤H的作業時，就會如後述般突然變得很困難。When the installation operation is carried out from the position of the maximum outer diameter Hm of the steering wheel H to the position range of the maximum outer diameter Hm of the steering wheel H (the part shown in B of FIG. 8), the steering wheel H and the steering wheel cover 10 are installed The gap between the steering wheel accommodating parts 14 becomes extremely narrow. In addition, because the steering wheel cover 10 itself is made of a material that is not easily stretched, the opening edges 16a, 16b of the steering wheel cover 10 facing the cut portion 12 will bend toward the inside, and the bent part will tightly touch the steering wheel. The surface of H is suddenly difficult to install the steering wheel cover 10 to the steering wheel H, as will be described later.

也就是說，為了把方向盤套10安裝到方向盤H，必須一邊用力拉伸方向盤套10使其環內徑變寬，一邊將捲曲的開口緣部16a、16b捲向內側。在沒有形成切除部之以往的方向盤套中，也必須勉強將不易伸展的方向盤套之開口緣部拉伸，捲起開口緣部，但是在本發明中，因為切除部18是設在從超過3點鐘方向的位置一直到接近9點鐘方向為止的範圍，所以，捲起作業最難進行之區域的切除部18之起端S以及末端T附近(圖8中，C所示之施有交叉影線(cross-hatching)的部分)成為自由端(寬鬆)，變成可用極小的力氣就能進行前述的捲起作業，如此一來，即可簡單且輕鬆地進行安裝作業。That is, in order to attach the steering wheel cover 10 to the steering wheel H, it is necessary to wind the curled opening edges 16a, 16b inward while pulling the steering wheel cover 10 to widen the ring inner diameter. In the conventional steering wheel cover without the cut-out part, the opening edge of the steering wheel cover, which is not easily stretched, must be stretched to roll up the opening edge. However, in the present invention, the cut-out part 18 is set from more than 3 The position at the o’clock direction is close to the range close to the 9 o’clock direction. Therefore, the area near the beginning S and the end T of the cutout 18 in the area where the rolling operation is the most difficult to perform (the cross is shown in Fig. 8, C) The cross-hatching part) becomes the free end (loose), and the aforementioned rolling operation can be performed with very little effort. In this way, the installation operation can be performed simply and easily.

在方向盤套10安裝後，因為開口緣部16a、16b(不設有切除部18的部分)是覆蓋方向盤H，所以，方向盤套10是緊密地被安裝在方向盤H上，在開車中即使有強大的力量施加於方向盤套10，方向盤套10也不會從方向盤H移位或脫離。After the steering wheel cover 10 is installed, because the opening edges 16a, 16b (the parts not provided with the cutout 18) cover the steering wheel H, the steering wheel cover 10 is tightly mounted on the steering wheel H, even if it is strong during driving. The force is applied to the steering wheel cover 10, and the steering wheel cover 10 will not be displaced or separated from the steering wheel H.

針對此點加以詳述的話，在方向盤套10的開口緣部16a中，不設有切除部18的部分係大於180度，所以，方向盤套10對於方向盤H的抓力和以往不設有切除部18的方向盤套相同，在安裝後，即使突然操作方向盤，也不會發生移位或捲曲的情形。 [實施例]To elaborate on this point, in the opening edge portion 16a of the steering wheel cover 10, the portion not provided with the cut-out portion 18 is greater than 180 degrees, so the grip of the steering wheel cover 10 on the steering wheel H is not provided with the cut-out portion in the past. The steering wheel cover of the 18 is the same. After installation, even if the steering wheel is suddenly operated, it will not shift or curl. [Example]

本案發明者對於前述的方向盤套10，針對(i)方向盤的安裝性、(ii)安裝後的貼合性、以及(iii)視覺美感來進行評價測試，證明其實用性。 (有關切除部18的起端S・末端T的位置) 針對切除部18，同時改變起端S與末端T的位置，也就是同時改變由水平線X、與連接線Y所成之俯角θ的大小，分別針對前述(i)～(iii)來進行評價，該連接線Y係連接環中心P與起端S(末端T)。此外，同時也針對安裝所需要的時間進行測量。其結果如表1所示。For the aforementioned steering wheel cover 10, the inventor of the present invention conducted evaluation tests on (i) the installation property of the steering wheel, (ii) the fit after installation, and (iii) the visual aesthetics, and proved its practicality. (Regarding the position of the start S and the end T of the cutout 18) For the cut portion 18, the positions of the starting end S and the end T are changed at the same time, that is, the size of the depression angle θ formed by the horizontal line X and the connecting line Y is changed at the same time, and the above-mentioned (i) to (iii) are respectively evaluated. The connecting line Y connects the ring center P and the starting end S (end T). In addition, the time required for installation is also measured. The results are shown in Table 1.

Figure 02_image001

從表1即可得知，俯角θ只要是在5°～12°的範圍即為實用，特別是當俯角θ為9°時，可得到最好的結果。 (有關切除部18的切取寬度) 在與方向盤套10之周方向正交的方向的剖面中，改變由連接直線M、以及連接直線N所成的角(切除角)β的大小，分別針對前述(i)～(iii)進行評價。其結果如表2所示，該連接直線M係連接切除部18形成前的開口緣部16a’、與管中心Q；該連接直線N係連接管中心Q、與中央部分20c。It can be seen from Table 1 that as long as the depression angle θ is in the range of 5°-12°, it is practical, and the best results can be obtained when the depression angle θ is 9°. (Regarding the cutting width of the cutout 18) In the cross section in the direction orthogonal to the circumferential direction of the steering wheel cover 10, the size of the angle (cut-off angle) β formed by the connecting straight line M and the connecting straight line N was changed, and the aforementioned (i) to (iii) were evaluated respectively. . As a result, as shown in Table 2, the connecting straight line M connects the opening edge 16a' and the tube center Q before the cutout 18 is formed; the connecting straight line N connects the tube center Q and the central portion 20c.

Figure 02_image003

從表2即可得知：切除角β只要是在40°～55°的範圍即為實用，當切除角β為45°～50°時為最佳。It can be seen from Table 2 that as long as the cut-off angle β is in the range of 40° to 55°, it is practical, and when the cut-off angle β is 45° to 50°, it is the best.
