Japanese Patent Application Laid-Open No. 2020-172191

However, the technology disclosed in Patent Document 1 is limited to lifting and lowering only within the luggage compartment, and it is not possible to lift and lower items while moving them from the inside to the outside of the luggage compartment.

The present invention has been developed in consideration of the above points, and aims to provide a vehicle lifting device and a method for using the vehicle lifting device, which raises and lowers items while loading and unloading them through the opening of the luggage compartment. Another object of the present invention is to provide a vehicle lifting device and a method for using the vehicle lifting device that can be folded up when not in use.

The vehicle lifting device of the present invention comprises:
A pair of fixing plates erected on the luggage compartment interior side of the vehicle;
a pair of movable plates that are moved up and down while passing through an opening of the vehicle from the inside of the luggage compartment to the outside of the luggage compartment;
a pair of link mechanisms in which one of the fixed plates and one of the movable plates are connected by two links, and the links are attached separately to one surface and the other surface of the fixed plate and the movable plate;
a pair of side plates attached to the inner surfaces of the pair of movable plates via connecting members with a gap therebetween so as not to interfere with the link;
an upper plate connecting upper ends of the pair of side plates;
a bottom plate that connects the lower ends of the pair of side plates and on which the transported object is placed,
The front and rear directions of the portion surrounded by the side plates, the top plate, and the bottom plate are open, so that the transported items can be loaded and unloaded from the bottom plate from either the front or the rear,
The object is transported from the inside of the luggage compartment, which is at a relatively high position, to the outside of the luggage compartment, which is at a relatively low position.

With the vehicle lifting device of the present invention, the side and bottom plates, which are integral with the movable plate, are raised and lowered to move in and out of the opening. This allows items placed on the bottom plate to be transported from the relatively higher position inside the luggage compartment to the lower position outside the luggage compartment. Furthermore, because the link mechanism has two links attached separately to one side and the other side of the fixed plate and movable plate, the link mechanism can operate beyond its dead point. This allows for a larger range of motion for the movable plate and its surrounding area. Furthermore, because the area enclosed by the side, top, and bottom plates is open in the front-to-rear direction, loading and unloading items is easy for both people inside the vehicle (inside the luggage compartment) and people outside the vehicle (outside the luggage compartment).

A preferred example of the vehicle lifting device of the present invention is:
The link mechanisms are configured so that the dead center of one link mechanism and the dead center of the other link mechanism are at different positions.

In a preferred embodiment of the vehicle lifting device of the present invention, the dead center of one link mechanism is different from the dead center of the other link mechanism, preventing one link mechanism from rotating forward and the other link mechanism from rotating reverse near their dead centers.

A preferred example of the vehicle lifting device of the present invention is:
A part of the upper plate is configured to be thin, and this thin part serves as a grip portion.

In a preferred example of the vehicle lifting device of the present invention, the gripping portion is provided on the upper plate, so that people inside the vehicle can easily grasp the gripping portion regardless of the position of the link mechanism. Furthermore, because part of the upper plate also serves as the gripping portion, the configuration can be simplified.

A preferred example of the vehicle lifting device of the present invention is:
The connecting member functions as a first stopper that prevents the link from descending any further when a part of the link abuts against the connecting member when the link mechanism is lowered.

In a preferred embodiment of the vehicle lifting device of the present invention, the connecting member also functions as a first stopper that determines the lower limit of the link mechanism when it is lowered, allowing for a simple device configuration.

A preferred example of the vehicle lifting device of the present invention is:
the bottom plate is composed of a connecting plate that connects the lower ends of the pair of side plates, and a spring-up plate that is attached to the connecting plate by a hinge so as to be rotatable upward,
The lifting plate fixing device is further provided to fix the lifting plate in a state where the lifting plate is rotated upward.

In a preferred embodiment of the vehicle lifting device of the present invention, the spring plate can be fixed in the raised position, allowing the vehicle lifting device to be made smaller when not in use.

A preferred example of the vehicle lifting device of the present invention is:
A second stopper is attached to the fixed plate to stop the link mechanism when the link mechanism is tilted toward the inside of the luggage compartment by a predetermined angle.

In a preferred embodiment of the vehicle lifting device of the present invention, the stopper can stop the side panel in a state where the link mechanism is tilted toward the inside of the luggage compartment by a predetermined angle. Here, the "predetermined angle" refers to the angle at which the link mechanism tends to tilt toward the inside of the luggage compartment due to the weight of the other components. This prevents the link mechanism from rotating significantly toward the inside of the luggage compartment.

A preferred example of the vehicle lifting device of the present invention is:
The fixing plate is attached to a wall surface on the inside of the luggage compartment or a structure in contact with the wall surface,
When the link mechanism is stopped by the second stopper, a portion of the fixed plate and the side plate, and a portion of the links in at least one of the link mechanisms are configured to overlap in a side view.

In a preferred embodiment of the vehicle lifting device of the present invention, the device is adjacent to the wall surface on the inside of the luggage compartment. Furthermore, when the link mechanism is stopped by the second stopper, the fixed plate, movable plate, and link overlap in a side view, reducing the depth. This allows the vehicle lifting device to be stored compactly when not in use.

A method of using the vehicle lifting device of the present invention includes:
A method of using the vehicle lifting device described above, comprising:
a preparation step of opening the opening and lowering the spring-up plate in a horizontal direction from a state in which the spring-up plate is rotated upward;
a loading step of loading the transported object onto the spring-up plate from inside the luggage compartment;
a lowering step of gripping the gripping portion, rotating the link mechanism to lower the movable plate through the opening, and moving the transported object to the outside of the luggage compartment;
a removal step of removing the transported object from the lift-up plate outside the luggage compartment;
an ascending step that grasps the grasping portion and rotates the link mechanism to pull the movable plate into the luggage compartment through the opening;
a storage step of rotating the spring-up plate upward and fixing it with the spring-up plate fixing device to close the opening,
The steps from the placing step to the raising step are repeated as necessary.

The method of using the vehicle lifting device of the present invention can achieve the same effects as the vehicle lifting device of the present invention described above.

As described above, the vehicle lifting device and method of using the vehicle lifting device of the present invention allow items to be lifted and lowered while being loaded and unloaded through the opening of the luggage compartment, facilitating the transfer of items from people inside the vehicle to people outside the vehicle. Another advantage is that the vehicle lifting device can be folded up into a compact size when not in use.

Figure 2(A) is a plan view of the fixed plate 11 and its surrounding structure, Figure 2(B) is a front view, Figure 2(C) is a left side view, and Figure 2(D) is a right side view. Figure 3(A) is a plan view of the movable plate 12 and its surrounding structure, Figure 3(B) is a front view, Figure 3(C) is a left side view, and Figure 3(D) is a right side view. Also, Figures 4 to 6(A) are left side views of the vehicle lifting device 1, and (B) are right side views.

First, we will explain an embodiment of the vehicle lifting device 1. As shown in Figures 1 to 3 and 7, the vehicle lifting device 1 of this embodiment includes a reinforcing plate 10, a fixed plate 11, a movable plate 12, link mechanisms 20 and 21, side plates 30, an upper plate 31, a bottom plate 33, a first stopper 40, and a second stopper 42.

The reinforcing plate 10 is installed below an opening 53, such as a window, on the wall surface 54 of the inside trunk 51 of the vehicle 50. In this embodiment, it is attached with one of its wide surfaces abutting the wall surface. The reinforcing plate 10 is not limited to the above configuration; for example, it can be attached with its wide surface horizontally. Furthermore, the reinforcing plate 10 is not limited to a plate-shaped member; there are no restrictions on its shape as long as it can firmly attach the fixing plate 11. Note that the reinforcing plate 10 is not a required component, and need not be provided if the strength of the fixing plate 11 is not an issue. In such cases, the fixing plate 11 can be attached directly to the wall surface 54 of the inside trunk 51, or to a structure 55, such as a countertop or desk, or to the floor of the trunk.

The fixed plates 11 are a pair of plate-like members that are erected on the reinforcing plate 10 at a predetermined distance, with their wide surfaces facing each other. Each fixed plate 11 has holes 24a and 24b for rotatably supporting two links 22a, 22b, 23a, and 23b.

The movable plates 12 are a pair of plate-like members that move up and down while passing through an opening 53 from the inside of the luggage compartment 51 to the outside of the luggage compartment 52, with their wide surfaces facing each other. Each movable plate 12, 12 also has holes 25a, 25b for pivotally supporting two links 22a, 22b, 23a, 23b.

The link mechanisms 20, 21 are realized by connecting each fixed plate 11, 11 and movable plate 12, 12 with two links 22a, 22b, 23a, 23b, and in this embodiment, a pair of four-bar link mechanisms 20, 21 are used. Furthermore, the two links 22a, 22b, 23a, 23b connecting the fixed plate 11 and movable plate 12 are attached separately to one surface (outer surface os) and the other surface (inner surface is) of the fixed plate 11 and movable plate 12.

This pair of link mechanisms 20, 21 is installed so that the dead centers of one (left) link mechanism 20 and the other (right) link mechanism 21 are different. This is achieved by having link attachment holes 24a, 24b, 25a, 25b in the fixed plate 11 and the movable plate 12 positioned differently on the left and right (see dimension lines a and b in Figures 2(C) and 2(D) and 3(C) and 3(D)). The fact that the dead centers of the link mechanisms 20, 21 are different can also be understood by looking at the distance between the links shown in Figures 4 and 5, which will be described later.

The side plates 30 are a pair of plate-like members that are attached to the sides of the movable plate 12 via connecting members 40 with a gap between them to prevent interference with the links 22b and 23b. These side plates 30 are also installed so that their wide surfaces face each other.

The upper plate 31 is a plate-like member that connects the upper ends of the pair of side plates 30. A portion of this upper plate 31 is configured to be thin, forming a grip portion 32 that can be grasped by a person inside the vehicle when operating the vehicle lifting device 1.

The bottom plate 33 is a plate-like member that connects the lower ends of the pair of side plates 30 and on which transported items (not shown) can be placed. While the bottom plate 33 may be constructed from a single member, in this embodiment it is composed of a connecting plate 34 and a spring-up plate 35. The connecting plate 34 is a plate-like member that connects the lower ends of the pair of side plates 30 and has the same width (depth) as the side plates 30. The spring-up plate 35 is a plate-like member that is attached to the connecting plate 34 by a hinge (not shown) so that it can rotate upward around an axis in the left-right direction. In this embodiment, the rear ends of the connecting plate 34 and the spring-up plate 35 are attached to each other by a hinge so that they can rotate.

A spring-up plate fixture 36 for fixing the spring-up plate 35 after it has been rotated upward is installed on the inner surface of the side panel 30. This spring-up plate fixture 36 has a notch 37 into which the end of the spring-up plate 35 fits, and is attached to the side panel 30 so that it can rotate upward via a hinge (not shown) (see arrow c in Figure 3(B)). The end of the spring-up plate 35 that has been rotated upward is then fitted into the notch 37 and fixed (see Figures 3(B) and (D)).

The first stopper 40 prevents the link mechanisms 20, 21 from descending more than a predetermined angle when the link mechanisms 20, 21 are rotated and lowered. In this embodiment, the connecting member 40 is used as the first stopper 40. Specifically, a portion of the connecting member 40 is chamfered 41 so that a portion of the links 22b, 23b abuts against the chamfered portion 41 (see Figures 4(A) and (B)).

The second stopper 42 prevents the link mechanisms 20, 21 from tilting toward the inside of the luggage compartment 51 by more than a predetermined angle when the link mechanisms 20, 21 are rotated and raised. This second stopper 42 is attached to the inner surface of the fixed plate 11, and a portion of the links 22b, 23b abuts against it. The second stopper 42 is positioned so that it can stop the link mechanisms 20, 21 when they are tilted toward the inside of the luggage compartment by a predetermined angle. When the links 22b, 23b abut against the second stopper 42, the links 22b, 23b and other components operated by the link mechanisms 20, 21 lean against the second stopper 42 due to their own weight.

When the links 22b, 23b are in contact with the second stopper 42, it is preferable that the fixed plate 11 and the side plate 30 at least partially overlap in side view (see Figures 5(A)(B) and 6(A)(B)). Furthermore, it is preferable that the link mechanisms 20, 21 are positioned near the dead center, and that at least one of the links 23a, 23b on either the left or right side of each pair of link mechanisms 20, 21 partially overlap in side view (see Figures 5(B) and 6(B)). With this configuration, when the vehicle lifting device 1 is raised toward the inside of the luggage compartment 51, the components such as the fixed plate 11, side plate 30, and link mechanisms 20, 21 are aligned and overlapped vertically in side view. This allows the vehicle lifting device 1 to be compact when raised toward the inside of the luggage compartment 51. Furthermore, by rotating the flip-up plate 35 upward when storing the vehicle lifting device 1, the size can be further reduced.

Furthermore, to achieve compactness during storage of the vehicle lifting device 1, the widths w1 and w2 (depth) of the fixed plate 11, movable plate 12, side plate 30, upper plate 31, and connecting plate 34 are preferably 12 centimeters or less, and preferably 10 centimeters or less. In this embodiment, the width w1 of the fixed plate 11 is 10 centimeters, and the width w2 of the movable plate 12, side plate 30, upper plate 31, and connecting plate 34 is 9 centimeters. As a result, the depth of the vehicle lifting device 1 during storage in this embodiment, excluding protrusions such as the hinge side of the upwardly rotated flip-up plate 35, can be a maximum of 19 centimeters, calculated by adding the width w1 of the fixed plate 11 (10 centimeters) to the width w2 of the movable plate 12, etc. (9 centimeters). Note that the actual depth w3 shown in Figure 6(B) is approximately 14.5 centimeters because approximately half the width of the movable plate 12 overlaps the fixed plate 11 in side view, and the depth w4 including the reinforcing plate 10 is also approximately 16.5 centimeters. Additionally, dimension w5, including protrusions, is approximately 18 centimeters.

Next, an embodiment of a method for using the vehicle lifting device will be described, taking into account each component of the vehicle lifting device 1 described above. The method for using the vehicle lifting device of this embodiment includes a preparation step, a loading step, a lowering step, a removal step, a lifting step, and a storage step.

The preparation step prepares the vehicle lifting device 1 for use. First, the opening 53 of the vehicle 50, such as a window, is opened. Next, from the state shown in Figures 6(A) and 6(B), the spring-up plate fixture 36 is rotated upward to remove the end of the spring-up plate 35 from the notch 37, and the spring-up plate 35 is lowered horizontally. This brings the device into the state shown in Figures 5(A) and 5(B), and the vehicle lifting device 1 is ready for use. At this time, portions of the links 22b and 23b are in contact with the second stopper 42.

Next, in the loading step, food-filled dishes, lunch boxes, and other items (not shown) are placed on the flip-up plate 35 from the inside of the luggage compartment 51. At this time, since the area above the flip-up plate 35 is open in the front-to-back direction with no back panel or the like, items can be easily placed from the inside of the luggage compartment 51.

Next, as the lowering step, the link mechanisms 20, 21 are rotated to move the movable plate 12, side plate 30, and associated components inside the opening 53 toward the outside of the luggage compartment 52, lowering them. At this time, a person inside the vehicle primarily grasps and operates the gripping portion 32 provided on the upper plate 31. When the lowering step is complete, the vehicle lifting device 1 is in the state shown in Figures 4(A) and (B), with portions of the links 22b, 23b abutting the first stopper 40.

Next, in the removal step, a person outside the vehicle removes and receives the transported item placed on the lift-up plate 35. Next, in the raising step, a person mainly inside the vehicle grasps and pulls up the gripping portion 32 with their hands, moving the movable plate 12, side plate 30, and associated components from the opening 53 to the inside of the luggage compartment 51 (Figures 5(A) and (B)). Then, the above-mentioned placement step through the raising step are repeated as necessary. Note that it is also possible to reverse the placement step and removal step and move the transported item from the outside of the luggage compartment 52 to the inside of the luggage compartment 51.

Next, as a storage step, the spring-up plate 35 is rotated upward from the state shown in Figures 5(A) and (B) and fixed with the spring-up plate fixing device 36 (Figures 6(A) and (B)). Next, the opening 53 is closed. This completes the method of using the vehicle lifting device. At this time, the links 22a, 22b, 23a, and 23b and the side plate 30 may be fixed to the fixed plate 11, etc., using a fixing mechanism (not shown) to prevent the link mechanisms 20, 21, etc. from moving due to vibrations while the vehicle 50 is in motion, etc.

As explained above, the vehicle lifting device 1 of this embodiment can move transported items from the luggage compartment inside 51, which has a difference in height, to the luggage compartment outside 52. This is particularly effective when the person outside the vehicle is a child, a physically disabled person, or the like, as it can move the transported items to a lower position.

In addition, by arranging the links 22a, 22b, 23a, and 23b separately on the front and back of the fixed plate 11 and the movable plate 12, the movable plate 12 can be moved to near the dead center. Furthermore, by changing the dead center positions of the left and right link mechanisms 20 and 21, it is possible to prevent abnormal operation such as the left and right links 22a, 22b, 23a, and 23b rotating in reverse relative to each other.

In addition, long, thin plates are used for the fixed plate 11, movable plate 12, side plate 30, and other components, reducing the depth of each component. Furthermore, when the vehicle lifting device 1 is stored or when the link mechanisms 20, 21 are abutting against the second stopper 42, the fixed plate 11 and side plate 30 are partially overlapping in a side view. Furthermore, the link mechanisms 20, 21 are also positioned near their dead points, with the links partially overlapping in a side view. This allows the depth of the vehicle lifting device 1 to be significantly reduced when the vehicle lifting device 1 is stored or when the link mechanisms 20, 21 are abutting against the second stopper 42, making effective use of the limited luggage compartment space.

The vehicle lifting device and method of using the vehicle lifting device described above are examples of the present invention, and the configuration can be modified as appropriate without departing from the spirit of the invention. For example, the side plates, top plate, and bottom plate can be integrally configured to have a rectangular shape with rounded corners when viewed from the front, or other shapes.
