Description

[Technical Field]

[0001] The present invention relates to a height-adjustable shelf support member and shelf support component for vehicles with foldable seats, such as those used in automobiles, trains, and airplanes. [Background technology]

[0002] The mainstream method for fixing this type of shelf board (23) inside a car is to fasten it to the vehicle body with bolts and nuts or screws. In recent years, when the vehicle shakes while driving, the method of removing the assist handle (7) that can be grasped by hand and fixing the shelf board (23) using the screw holes for fixing the assist handle has been used, but this is not optimal from a safety standpoint.

[0005] The problem we are trying to solve is that installing this type of shelf (23) becomes even more difficult when limited to minivans. This is because minivans are often used as luggage compartments when the third-row seats are not needed, and the third-row seats are often stowed. There are two storage methods: one is to flip up the seats that are folded up at the top of the vehicle's side, and the other is to fold the seats and slide them under the floor at the rear of the vehicle. The problem here is that in vehicles with folding third-row seats, it is difficult to secure the support members for the shelf (23). There are no sturdy locations inside the vehicle where holes can be drilled for securing the members, and even if the screw holes for the assist handle are used, the folded-up third-row seats get in the way, making it difficult to install the shelf support members. In addition, the shelf (23) cannot be easily and safely installed when the folding third-row seats (hereinafter referred to as the third-row seats) are flipped up.

[0006] Another problem that needs to be solved is the creation of a base using round or square pipes, on which a top plate is placed, but with this method the pipe legs narrow the luggage space and are not easy to install. The biggest problem is that in cars with underfloor storage (27), the pipe legs get in the way, making it impossible to open the lid to access the storage space. [Means for solving the problem]

[0007] The height adjustment member and shelf support part of the present invention is a height adjustment member that can be fixed to a folding seat and adjust the height of a shelf (23), and has a side folding part (1), an upper folding part (2), a shelf support surface folding part (3), and a lower folding part (4) that is shorter than the upper folding part (2), and the shelf support surface folding part (3) is provided with a plurality of cutout holes (3a) for adjusting the height of the supported shelf (23), and the side folding part (1) is formed so that the backrest (5) of the folding seat is in contact with the seat surface. The folding seat back is inserted into the gap (10) between the backrest (8) and the seat (9) that is created when the folding seat back is folded to the side (6), and is fixed so as to sandwich the backrest (8) and the seat (9). The folding seat back has a length equal to or greater than the thickness of the side of the seat (9), and is connected to the upper folding portion (2). The upper folding portion (2) is connected to the shelf support folding portion (3) (13), and the shelf support folding portion (3) is connected to the lower folding portion (4), and the lower folding portion (4) is formed so as to abut against the underside of the folding seat (14) (15).

[0008] The shelf support component of the present invention is a shelf support component used in a height adjustment member for a folding seat, and has an upper locking portion (17) that locks into the cutout hole (3a), an intermediate bridge portion (18) that is connected to the upper locking portion and folded back, and a lower locking portion (19) that is inserted into a locking hole (21) for locking the shelf provided on the side of the shelf (23) to lock the shelf (23), and can support the shelf (23) safely and easily. [Effects of the Invention]

[0009] The height adjusting member and shelf support component of the present invention enable the shelf (23) to be easily and safely installed when the folding seat is in the raised position. [Brief explanation of the drawings]

[0011] The height-adjustable member of the present invention has side folds (1), an upper fold (2), a shelf support surface fold (3), and a lower fold (4) for securing a shelf (23) to the folding seat. The height-adjustable member is inserted and secured in the gap between the seat and back of the folded-up third-row seat shown in Figure 2(c) when the seat is stowed. Furthermore, the lower fold (4) contacts the underside of the seat to stabilize the height-adjustable member and prevent it from flapping when the vehicle is moving. The shelf support surface fold (3) has multiple cutout holes (3a) for adjusting the height of the supported shelf (23). The height-adjustable member of the present invention can be easily and safely installed when the folding third-row seat is stowed. The shelf support component of the present invention shown in Figure 4(a) is used to secure the height-adjustable member and shelf (23).

[0012] By inserting the shelf into the gap (10) between the seat back (8) and seat cushion (9) that opens when the third-row seats are stowed, preparation for installing the shelf (23) can be easily and safely performed without drilling screw holes in the vehicle body or removing the existing assist grip (7). Furthermore, the height adjustment member of the present invention allows the shelf (23) to be secured using the support component of the present invention via the cutout (3a) in the shelf support surface fold (3), making it possible to adjust the height of the shelf (23). Another advantage is that the presence of the bottom fold (4) (15) absorbs sway and vibration during vehicle operation, thereby maintaining the shelf (23) in a stable state. This allows for the storage of camping equipment, disaster prevention supplies, and other items, as well as securing them using tie-down straps. Some vehicles also have underfloor storage, many of which are equipped with lids. In the case of external shelves that use a base made of processed pipes, the pipe legs obstruct the ability to open the lid (28) of the underfloor storage compartment (27). However, the shelf (20) using the height-adjustable member and shelf support part of the present invention does not have legs, making it possible to open the lid (28) of the underfloor storage compartment (27). Another major advantage is that when passenger numbers increase, the shelf (23), the height-adjustable member, and shelf support part of the present invention can be easily and safely removed, allowing the third-row seats to be quickly extended. Furthermore, while the height-adjustable member is not limited to shelves and can be used as a simple luggage hanger using hooks, and while the height-adjustable member requires a strap to secure luggage, the present invention can also be applied to trains, airplanes, ships, and other vehicles. Furthermore, the height-adjustable member of the present invention has a symmetrical shape, allowing it to be stacked face-to-face for space-saving storage (32). The shelf support part of the present invention is also small and easy to store (31), which is another major advantage. The height adjustment members are made of aluminum for strength and light weight, while the shelf support parts are made of iron or stainless steel for strength. [Example]

[0013] Fig. 1(a) is a perspective view of the height adjustment member of the present invention, and (b) is a side view. Fig. 2(a) is a view of the third-row seat in a seatable state (installed state), (b) is a view of the seat back (5) folded toward the seat surface (6), and (c) is a view of the third-row seat fully folded up (stored) on the rear window side of the vehicle. Figure 3(a) is a diagram showing the side fold of the height adjustment member being inserted into the gap between the backrest and seat of the third-row seat that appears when the seat is stored (flipped up) toward the rear window in the vehicle, (b) is a diagram showing the state in which the side fold of the height adjustment member is fully inserted and the top fold of the height adjustment member is engaged with the side of the seat that appears when the third-row seat is stored, (c) is a diagram showing the bottom fold of the fixed height adjustment member contacting the underside of the seat that appears when the third-row seat is stored, and (d) is a diagram showing the state in which the height adjustment member is installed on both the left and right sides of the rear of the vehicle.

[0014] The side fold portion (1) of the height adjustment member shown in Figure 1(a) fits into the gap (10) between the backrest (8) and seat (9) when the third-row seats are stowed as shown in Figure 3(a). The width and length of the side fold portion (1) were optimized by investigating the frictional resistance and pressure that occurs in the gap (10) between the backrest (8) and seat (9). The side fold portion (1) is connected to the top fold portion (2) to prevent the height adjustment member from falling off the third-row seats when they are stowed as shown in Figure 2(c). The length of the top fold portion (2) is optimized so that it hangs over the side of the seat (9) when the third-row seats are stowed as shown in Figure 3(b). The shelf support surface fold portion (3) is connected to the upper fold portion (2) and has an optimum length so that it comes into contact with the underside (14) of the seat surface (9) that appears when the third-row seats are stowed as shown in Figure 3(c). The third fold portion (3) is connected to the lower fold portion (4), and the lower fold portion (4) has an optimum length so that it comes into contact with the underside (14) of the seat surface that appears when the third-row seats are stowed as shown in Figure 3(c). As a result, the height adjustment member can be securely fixed to the third-row seats in the stowed position shown in Figure 2(c), as shown in Figure 3.

[0015] Fig. 4(a) is a diagram of the shelf support part of the present invention for fixing a shelf to the height-adjustable member of the present invention, (b) is a diagram of the process of fixing the shelf to the shelf support part, (c) is a diagram of the rear left side of the vehicle interior with the shelf installed on the height-adjustable member, and (d) is a diagram of the rear left side of the vehicle interior with the shelf fixed to the height-adjustable member. Fig. 5(a) is a diagram of the state in which the front left side of the shelf is supported by a belt, and (b) is a diagram of the belt mentioned above being supported in the buckle hole on the back of the seat that appears when the third-row seats are stowed. (c) is a diagram of the state in which the shelf is installed on the left side of the vehicle interior.

[0016] The shelf support component of the present invention shown in Figure 4(a) has been optimized for its folding angle and folding length to easily and safely secure the height-adjusting members and shelf (23) as shown in Figure 4(b). As a result, the shelf (23) is supported (13) by the combination of the height-adjusting members as shown in Figures 4(c) and 4(d). As shown in Figure 5(a), a hole (24) is provided in the side of the shelf (23) on the left front side so that a buckled belt (26) can be hung. The buckled belt (26) is passed through the hole (24), and the buckle is inserted into the buckle hole (25) for securing the third-row seats when they are stowed, which appears when the third-row seats are stowed, as shown in Figure 5(b). The belt length is adjusted to secure the shelf horizontally. [Example]
