Description

[Technical field]

[0001] The present invention relates to a stay that is provided, for example, in a driver's cab of a bodyd vehicle. [Background technology]

[0002] 2. Description of the Related Art A stay is known which is used to support an object by an A-pillar in a driver's cab of a vehicle. As one example, Patent Document 1 discloses a second fixing part (corresponding to a stay) that is integral with an assist grip attached to the A-pillar, extends downward from the lower end of the assist grip, and supports a monitor, which is a support object. On the other hand, in a vehicle equipped with a device for a specific use or purpose, an operation box that enables the device to be operated from within the driver's cab may be disposed in front of the driver's seat. When such an operation box is supported by the A-pillar as a support, the external force applied to the support by the operator's operation is large, and there is a risk that a stay consisting of a second fixing part fixed only to the lower end of the assist grip as described above may not be able to ensure sufficient rigidity. Therefore, in order to ensure sufficient rigidity while supporting even such a support object to which a relatively large external force is applied, it is possible to consider using, for example, a stay that has a mounting part that extends in one direction along the interior side of the A-pillar and a support part that extends from the mounting part and supports the support object, the mounting part having two fixing parts that are spaced apart from each other, and that is fixed to the A-pillar via the two fixing parts.

[0003] [Patent Document 1] JP 2020-37334 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, safety devices that monitor driver operation errors have made great strides, and for example, fixed objects such as warning lights that encourage the driver to avoid operating errors are sometimes provided on the inside side of the A-pillar. In such a case, with a stay having fixing portions at two locations as described above, there is a risk that the fixed object and the mounting portion will interfere with each other, making it difficult to fix the mounting portion to the A-pillar.

[0005] The present invention has been made in consideration of the current problems described above, and has an object to provide a stay that supports a support object located in front of the driver's seat, and that can be attached to the A-pillar in a state of high rigidity without interfering with a fixed object, even if a fixed object is provided on the side of the A-pillar on the interior side of the vehicle, for example. [Means for solving the problem]

[0006] The problem to be solved by the present invention has been described above, and the means for solving this problem will now be described.

[0007] That is, the stay of the present invention is a stay that supports a support located in front of the driver's seat, and comprises an attachment portion that is attached to an A-pillar, and a support portion that extends from the attachment portion and supports the support, the attachment portion has a first fixed portion and a second fixed portion that are fixed to the interior side of the A-pillar and are arranged spaced apart from each other, and a connection portion that connects the first fixed portion and the second fixed portion, and the connection portion has a curved shape that convex in a direction away from the driver's seat with respect to an imaginary straight line connecting the first fixed portion and the second fixed portion.

[0008] With this configuration, even if a fixed object is provided between the first fixed portion and the second fixed portion on the interior side of the A-pillar, the connection portion can be positioned so as to bypass the fixed object, so that the stay can be attached to the A-pillar via the mounting portion without interfering with the fixed object.

[0009] In addition, in the stay according to the present invention, it is preferable that an assist grip is provided on the A-pillar, and the mounting portion is fixed to the A-pillar by fastening the first fixing portion and the second fixing portion together with the assist grip.

[0010] With this configuration, the stay of the present invention is firmly fixed to the A-pillar together with the assist grip via the first fixing portion and the second fixing portion, thereby preventing rattling of the mounting portion attached to the A-pillar due to micro-vibrations caused by driving the vehicle. In addition, by fastening the stay together with the assist grip, there is no need to provide a separate member for attaching the stay to the A-pillar, which prevents an increase in the number of parts that make up the stay.

[0011] In the stay according to the present invention, it is preferable that a convex end of the connection portion at the attachment part is located on the driver's seat side with respect to a side edge portion of the A-pillar opposite to the driver's seat side.

[0012] With this configuration, the convex end of the connection part does not protrude onto the side of the A-pillar opposite the driver's seat, i.e., the windshield side, and does not obstruct the forward visibility of the driver seated in the driver's seat.

[0013] Furthermore, in the stay according to the present invention, it is preferable that the second fixed portion is located downward relative to the first fixed portion, the mounting portion has a suspension portion extending downward from the second fixed portion along the imaginary straight line, and the support portion extends from the extending end of the suspension portion toward the support.

[0014] With this configuration, the support portion is positioned near the dashboard, and does not significantly impede the forward visibility of the driver seated in the driver's seat. Effect of the Invention

[0015] The present invention has the following advantages. In other words, with the stay according to the present invention, even if a fixed object is provided on the vehicle interior side of the A-pillar, it can be attached to the A-pillar with high rigidity without interfering with the fixed object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Next, an embodiment of the present invention will be described with reference to FIGS. For the sake of convenience in the following description, in Figures 1 to 4, the forward movement direction of the vehicle 100 is defined as the forward direction, and the front-rear, left-right, and up-down directions of the vehicle 100 and the stay 1 are indicated as shown by the arrows in the figures.

[0018] The stay 1 in this embodiment is for supporting a support 103 arranged in front of a driver's seat 102 in a driver's cab 101 of a vehicle 100 by an A-pillar 104, as shown in FIG. 2(a).

[0019] Here, the vehicle 100 in this embodiment is a vehicle mounted with equipment for a specific use or purpose, such as a garbage truck, and an example of the support 103 is an operation box that allows the mounted equipment to be operated within the driver's cab 101. In addition, in the vehicle 100, an assist grip 106 is attached to the side of the A-pillar 104 on the inside side of the vehicle (the driver's cab 101 side) so as to protrude toward the driver's seat 102 side (the rear side in this embodiment), and a fixed object 105 such as a warning light to urge the driver to avoid erroneous operation is attached at a position avoiding the assist grip 106 (more specifically, at a position between a pair of connecting portions 106b·106b described later).

[0020] Although details will be described later, even if a fixed object 105 is provided on the vehicle interior side of the A-pillar 104, the stay 1 is configured to be able to be attached to the A-pillar 104 without interfering with the fixed object 105 and with high rigidity.

[0021] It should be noted that the vehicle 100 is not limited to a refuse compactor, but may be any type of vehicle equipped with devices suited to a specific use or purpose. In other words, a garbage truck is a vehicle equipped with equipment for loading and transporting garbage, but other examples include a concrete pump truck equipped with a device for pumping concrete, a tanker truck equipped with a container for storing and transporting hazardous materials, and a so-called special purpose vehicle equipped with equipment for special purposes, such as an emergency vehicle.

[0022] Furthermore, vehicle 100 may be a van or flatbed truck that is generally used as a cargo-carrying vehicle, which has a wide variety of uses and purposes and is equipped with equipment (cargo bed) appropriate for that use or purpose, or a trailer in general that has equipment (towed vehicle) appropriate for that use or purpose, such as a flatbed semi-trailer.

[0023] Furthermore, the support 103 is not limited to the above-mentioned operation box, and may be anything that is disposed in front of the driver's seat 102, such as a monitor.

[0024] The stay 1 mainly includes a mounting portion 2 that is mounted to an A-pillar 104 of a vehicle 100 , and a support portion 3 that extends from the mounting portion 2 and supports a support 103 . Here, as shown in FIG. 2(b), the support part 3 consists of a rectangular plate-like member extending in one direction, and is arranged at the lower end of the mounting part 2 (more specifically, the suspension part 24 described later) so that its plane faces approximately in the vertical direction and its extension direction faces toward the center of the cab 101 (to the left in this embodiment).

[0025] Then, the support 103 is placed on the upper surface of the support portion 3, and then fixed to the support portion 3 by a commercially available fastening member or the like. As a result, the support 103 is supported by the inside side of the A-pillar 104 via the stay 1.

[0026] As shown in Figure 1(a), the mounting portion 2 has a first fixing portion 21, a second fixing portion 22 arranged at a distance below the first fixing portion 21, a connection portion 23 connecting the first fixing portion 21 and the second fixing portion 22, and a hanging portion 24 extending downward from the second fixing portion 22.

[0027] The first fixing portion 21 has a first through hole 21a and a first spacer 21b. The first through hole 21a is provided at the upper end of the connection portion 23 and is formed with its axial direction perpendicular to the direction separating the first fixed portion 21 and the second fixed portion 22 (in this embodiment, the vertical direction). The first spacer 21b is made of a cylindrical member and, as shown in FIG. 1(b), is arranged coaxially with the first through hole 21a and on one side in the axial direction (the right side in this embodiment) of the first through hole 21a.

[0028] On the other hand, as shown in FIG. 1(a), the second fixing portion 22 has a second through-hole 22a and a second spacer 22b. The second through hole 22a is provided at the lower end of the connection portion 23 and, similar to the first through hole 21a, is formed with its axial direction perpendicular (left-right) to the spacing direction (up-down direction) between the first fixed portion 21 and the second fixed portion 22. Similarly to the first spacer 21b, the second spacer 22b is also made of a cylindrical member and, as shown in FIG. 1(b), is arranged coaxially with the second through hole 22a and on one side (right side) of the second through hole 22a in the axial direction.

[0029] A pair of restriction groove portions 104a-104a spaced apart from each other in the vertical direction are provided on the vehicle interior side of the A-pillar 104. The mounting portion 2 is fixed to the A-pillar 104 by means of commercially available fastening members or the like via the first through hole 21a and the second through hole 22a after the first spacer 21b and the second spacer 22b are respectively inserted into the pair of restriction groove portions 104a-104a. In other words, the mounting portion 2 is firmly fixed to the vehicle interior side surface of the A-pillar 104 by two fixing portions consisting of the first fixing portion 21 and the second fixing portion 22.

[0030] As shown in FIG. 1(a), for example, the connection portion 23 is made of a band-shaped flat plate member and is disposed with its flat portion facing the axial direction (left-right direction) of the first through hole 21a (or the second through hole 22a). As described above, the first through hole 21a and the second through hole 22a are provided at the upper end and the lower end of the connection portion 23, respectively.

[0031] The connection portion 23 has a shape that is curved into an approximately trapezoidal shape so as to convex in a direction away from the driver's seat 102 (see Figure 2(a)) (forward in this embodiment) with respect to the imaginary straight line L connecting the first fixing portion 21 (more specifically, the axis G1 of the first through hole 21a) and the second fixing portion 22 (more specifically, the axis G2 of the second through hole 22a).

[0032] In addition, the shape of the connection portion 23 may be any shape that convex in the direction away from the driver's seat 102 (forward) with respect to the imaginary straight line L, and may be, for example, a U-shape or an arc shape.

[0033] Here, when the mounting portion 2 is attached to the A-pillar 104, the front end portion 23a, which is the convex end portion of the connection portion 23, is configured to be located on the driver's seat side (in this embodiment, the rear side) relative to the side edge portion of the A-pillar 104 opposite the driver's seat 102 side (in this embodiment, the front edge portion 104b).

[0034] Therefore, the front end 23a of the connection portion 23 protrudes forward of the A-pillar 104 and is present on the windshield 107 (see FIG. 4) side, and does not obstruct the forward visibility of the driver seated in the driver's seat 102.

[0035] As described above, the assist grip 106 is provided on the side surface of the A-pillar 104 facing the interior of the vehicle. As shown in FIG. 3, the assist grip 106 is configured in a generally U-shape and is composed of a gripping portion 106a extending generally in the vertical direction and a pair of connecting portions 106b extending generally forward from both ends of the gripping portion 106a.

[0036] The assist grip 106 is attached to the A-pillar 104 at the extending ends of the pair of connecting portions 106b, 106b with the first fixing portion 21 and the second fixing portion 22 of the mounting portion 2 sandwiched therebetween. That is, as shown in FIG. 4, the mounting portion 2 is fixed to the A-pillar 104 with the first fixing portion 21 and the second fixing portion 22 fastened together with the extended ends of a pair of connecting portions 106b·106b of the assist grip 106.

[0037] With this configuration, the stay 1 is firmly fixed to the A-pillar 104 together with the assist grip 106 via the first fixing portion 21 and the second fixing portion 22 of the mounting portion 2, thereby preventing rattling of the mounting portion 2 attached to the A-pillar 104 due to micro-vibrations caused by driving the vehicle 100 (see Figure 2(a)). In addition, by fastening together with the assist grip 106, there is no need to provide a separate member for attaching the stay 1 to the A-pillar 104, and an increase in the number of parts constituting the stay 1 can be prevented.

[0038] As described above, the suspension portion 24 is arranged to extend downward from the second fixed portion 22, and is formed by a band-shaped flat plate member forming the connection portion 23 extending downward along the imaginary straight line L, for example as shown in Figure 1(a).

[0039] Here, as shown in FIG. 1(b), a fitting hole portion 24a penetrating in the thickness direction (left-right direction in this embodiment) is provided at the lower end of the hanging portion 24, and the support portion 3 is fixed to the hanging portion 24 by welding or the like with one of its extending ends (the right end portion in this embodiment) inserted into the fitting hole portion 24a. As a result, the support part 3 is positioned to extend from the lower end, which is the extended end of the hanging part 24, in a direction toward the support 103, that is, in the left direction toward the center of the driver's cab 101, and is firmly fixed to the hanging part 24.

[0040] With this configuration, for example as shown in FIG. 4, the support portion 3 is positioned near the upper side of the dashboard 108 in the driver's cab 101, and does not significantly obstruct the forward visibility of the driver seated in the driver's seat 102.

[0041] As described above, the stay 1 in this embodiment is a stay that supports the support 103 located in front of the driver's seat 102, and includes an attachment portion 2 that is attached to the A-pillar 104, and a support portion 3 that extends from the attachment portion 2 and supports the support 103. In addition, the mounting portion 2 has a first fixing portion 21 and a second fixing portion 22 that are fixed to the interior side of the A-pillar 104 and are arranged at a distance from each other, and a connection portion 23 that connects the first fixing portion 21 and the second fixing portion 22. The connecting portion 23 is characterized by having a curved shape that protrudes in a direction away from the driver's seat 102 with respect to the imaginary straight line L that connects the first fixing portion 21 and the second fixing portion 22.

[0042] With this configuration, even if the above-mentioned fixed object 105 is attached to the inside side of the A-pillar 104 at a position that avoids the assist grip 106, for example as shown in Figure 3, by arranging the first fixing part 21 and the second fixing part 22 on both the upper and lower sides of the fixed object 105, respectively, it is possible to arrange the connection part 23 so as to bypass the fixed object 105 to the front side, so that the stay 1 can be attached to the A-pillar 104 via the mounting part 2 without interfering with the fixed object 105.

[0043] Therefore, according to the stay 1 of this embodiment, even if a fixed object 105 is provided on the vehicle interior side of such an A-pillar 104, it can be attached to the A-pillar 104 with high rigidity via two fixing parts consisting of the first fixing part 21 and the second fixing part 22 without interfering with the fixed object 105.

[0044] It should be noted that the present invention is not limited to the above-described embodiments, which are merely illustrative, and that the present invention can of course be embodied in various other forms without departing from the spirit of the present invention. The scope of the present invention is indicated by the claims, and further includes the equivalent meanings set forth in the claims, and all modifications within the scope of the claims.
