[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-172191 Summary of the Invention [Problem to be solved by the invention]

[0004] 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 the article while moving it from the inside of the luggage compartment to the outside of the luggage compartment.

[0005] The present invention has been made in consideration of the above points, and aims to provide a vehicle lifting device and a method of using the vehicle lifting device that lifts and lowers transported items while loading and unloading them through an opening in a luggage compartment. Another object of the present invention is to provide a vehicle lifting device and a method of using the vehicle lifting device that can be folded up when not in use. [Means for solving the problem]

[0006] 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; a bottom plate that connects the lower ends of the pair of side plates and on which the transported object is placed, The top of the bottom plate is open in the front-rear direction, so that the transported goods can be put in and taken out from the bottom plate from either the front or the back, 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, 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.

[0007] 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; a bottom plate that connects the lower ends of the pair of side plates and on which the transported object is placed, The top of the bottom plate is open in the front-rear direction, so that the transported goods can be put in and taken out from the bottom plate from either the front or the back, 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, when the link mechanism is stopped by the second stopper, a portion of the fixed plate and a portion of the side plate, and a portion of the links in at least one of the link mechanisms, overlap in a side view, 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.

[0008] Further, other examples of the vehicle lifting device of the present invention and a method of using the vehicle lifting device will be described.

[0009] 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.

[0010] According to the vehicle lifting device of the present invention, the side and bottom plates, which are integral with the movable plate, are moved up and down to be inserted and removed through the opening. This allows an object 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, the link mechanism has two links attached separately to one side and the other side of the fixed plate and the movable plate, allowing the link mechanism to operate beyond its dead point. This allows for a larger operating range for the movable plate and its surrounding area. Furthermore, because the area surrounded by the side, top, and bottom plates is open in the front-to-rear direction, it is easy for both people inside the vehicle (inside the luggage compartment) and people outside the vehicle (outside the luggage compartment) to insert and remove objects.

[0011] 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.

[0012] In a preferred example of the vehicle lifting device of the present invention, the dead point of one link mechanism is different from the dead point of the other link mechanism, thereby preventing the phenomenon in which one link mechanism rotates forward and the other link mechanism rotates reverse near the dead point.

[0013] 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.

[0014] In a preferred embodiment of the vehicle lifting device of the present invention, the gripping portion is provided on the upper plate, so that a person inside the vehicle can easily grasp the gripping portion regardless of the position of the link mechanism. In addition, since a part of the upper plate also serves as the gripping portion, the configuration can be simplified.

[0015] 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.

[0016] According to a preferred example 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, so that the structure of the device can be simplified.

[0017] 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.

[0018] According to a preferred example of the vehicle lifting device of the present invention, the spring-up plate can be fixed in the raised state, so that the vehicle lifting device can be made small when not in use.

[0019] 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.

[0020] 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 inwardly of the trunk by a predetermined angle. Here, the predetermined angle refers to the angle at which the link mechanism tends to tilt inwardly of the trunk due to the weight of the other components. This prevents the link mechanism from rotating too far inwardly of the trunk.

[0021] 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.

[0022] In a preferred embodiment of the vehicle lifting device of the present invention, the device is adjacent to the wall surface inside the luggage compartment. When the link mechanism is stopped by the second stopper, the fixed plate, the movable plate, and the link overlap in a side view, reducing the depth. This allows the vehicle lifting device to be stored compactly when not in use.

[0023] 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.

[0024] According to the method for using the vehicle lifting device of the present invention, it is possible to achieve the same effects as those of the vehicle lifting device of the present invention described above. [Effects of the Invention]

[0025] As described above, the vehicle lifting device and the method of using the vehicle lifting device of the present invention allow transported items to be lifted and lowered while being loaded and unloaded through the opening of the luggage compartment, making it easy to hand over items from people inside the vehicle to people outside the vehicle. Another effect is that the vehicle lifting device can be folded up when not in use. [Brief explanation of the drawings]

[0027] Hereinafter, embodiments of the vehicle lifting device 1 and a method of using the vehicle lifting device of the present invention will be described in detail with reference to the accompanying drawings. Fig. 2(A) is a plan view of the fixed plate 11 and its surrounding configuration, Fig. 2(B) is a front view, Fig. 2(C) is a left side view, and Fig. 2(D) is a right side view. Fig. 3(A) is a plan view of the movable plate 12 and its surrounding configuration, Fig. 3(B) is a front view, Fig. 3(C) is a left side view, and Fig. 3(D) is a right side view. In addition, Figs. 4 to 6(A) are left side views of the vehicle lifting device 1, and (B) are right side views.

[0028] 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, 21, side plates 30, an upper plate 31, a bottom plate 33, a first stopper 40, and a second stopper 42.

[0029] The reinforcing plate 10 is installed below an opening 53, such as a window, on a wall surface 54 on the inside 51 of the trunk of the vehicle 50, and in this embodiment, it is attached with one of its wide surfaces abutting against the wall surface. The reinforcing plate 10 is not limited to the above-described form, and for example, it can be attached with its wide surface horizontal. Furthermore, the reinforcing plate 10 is not limited to a plate-shaped member, and its shape is not limited as long as it can firmly attach the fixing plate 11. Note that the reinforcing plate 10 is not an essential component, and may not be provided if there are no problems with the strength, etc., of the installation of the fixing plate 11. In such a case, the fixing plate 11 can be attached directly to the wall surface 54 on the inside 51 of the trunk, or to a structure 55, such as a countertop or desk, or to the floor of the trunk.

[0030] The fixed plates 11 are a pair of plate-like members that are erected at a predetermined interval on the reinforcing plate 10, with their wide surfaces facing each other. Each fixed plate 11 is provided with holes 24a and 24b for rotatably supporting two links 22a, 22b, 23a and 23b.

[0031] The movable plates 12 are a pair of plate-like members that move up and down while passing through an opening 53 from an inside of the luggage compartment 51 to an outside of the luggage compartment 52, and their wide surfaces face each other. Each of the movable plates 12, 12 is also provided with holes 25a, 25b for pivotally supporting two links 22a, 22b, 23a, 23b.

[0032] The link mechanisms 20 and 21 are realized by connecting each of the fixed plates 11 and the movable plates 12 with two links 22a, 22b, 23a, and 23b, and in this embodiment, a pair of four-bar link mechanisms 20 and 21 are used. The two links 22a, 22b, 23a, and 23b connecting the fixed plate 11 and the 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 the movable plate 12.

[0033] The pair of link mechanisms 20, 21 are 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, which are provided in fixed plate 11 and movable plate 12, in different positions 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.

[0034] The side plates 30 are a pair of plate-like members that are attached to the side surfaces of the movable plate 12 via connecting members 40 with a gap between them so as not to interfere with the links 22b and 23b. The side plates 30 are also installed so that their wide surfaces face each other.

[0035] The upper plate 31 is a plate-like member that connects the upper ends of the pair of side plates 30. A portion of the upper plate 31 is configured to be thin, so that this portion serves as a grip portion 32 that can be grasped by a person inside the vehicle when operating the vehicle lifting device 1.

[0036] 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 objects (not shown) are placed. This bottom plate 33 may be formed from a single member, but in this embodiment it is formed from 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 as to be rotatable 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 rotatably attached to each other by the hinge.

[0037] A spring-up plate fixture 36 for fixing the spring-up plate 35 that has been rotated upward is installed on the inner surface of the side plate 30. This spring-up plate fixture 36 is provided with a notch 37 into which the end of the spring-up plate 35 fits, and is attached to be rotatable upward by a hinge (not shown) (see arrow c in FIG. 3(B)). Then, the end of the spring-up plate 35 that has been rotated upward is fitted into the notch 37 and fixed (see FIGS. 3(B)(D)).

[0038] The first stopper 40 is intended to prevent 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 part of the connecting member 40 is chamfered 41 so that a part of the links 22b, 23b abuts against the chamfered part 41 (see FIGS. 4(A) and (B)).

[0039] The second stopper 42 prevents the link mechanisms 20, 21 from tilting toward the inside of the trunk 51 by more than a predetermined angle when the link mechanisms 20, 21 are rotated and raised. The second stopper 42 is attached to the inner surface of the fixed plate 11, and a portion of the links 22b, 23b abuts against the second stopper 42. The second stopper 42 is positioned so that the link mechanisms 20, 21 can be stopped when the link mechanisms 20, 21 are tilted toward the inside of the trunk by about 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.

[0040] Here, 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 a side view (see FIGS. 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 a side view (see FIGS. 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, the side plate 30, and the link mechanisms 20, 21 are aligned and overlapped vertically in a side view. This allows the vehicle lifting device 1 to be compact when raised toward the inside of the luggage compartment 51. Furthermore, when the vehicle lifting device 1 is stowed, the size can be further reduced by rotating the flip-up plate 35 upward.

[0041] Furthermore, to reduce the size of the vehicle lifting device 1 during storage, 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 more 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 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), not including protrusions such as the hinge side of the upwardly rotated flip-up plate 35. The actual depth w3 shown in FIG. 6(B) is approximately 14.5 centimeters because approximately half the width of the movable plate 12 overlaps the fixed plate 11 in a side view, and the depth w4 including the reinforcing plate 10 is also approximately 16.5 centimeters. Also, the dimension w5 including the protrusions is approximately 18 centimeters.

[0042] Next, an embodiment of a method for using the vehicle lifting device will be described based on each of the components of the above-mentioned vehicle lifting device 1. 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.

[0043] 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 FIGS. 6(A) and 6(B), the spring-up plate fixing device 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 vehicle lifting device 1 into the state shown in FIGS. 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.

[0044] Next, as a loading step, food-filled dishes, lunch boxes, and other items (not shown) are loaded onto the flip-up plate 35 from inside the luggage compartment 51. At this time, since the area above the flip-up plate 35 is open in the front-to-rear direction with no back panel or the like, loading can be easily performed from inside the luggage compartment 51.

[0045] Next, as the lowering step, the link mechanisms 20, 21 are rotated to move and lower the movable plate 12, side plate 30, and associated components inside the opening 53 to the outside of the luggage compartment 52. At this time, a person inside the vehicle mainly grasps and operates the gripping portion 32 provided on the upper plate 31. When the lowering step is completed, the vehicle lifting device 1 is in the state shown in Figures 4(A) and (B), with parts of the links 22b, 23b abutting against the first stopper 40.

[0046] 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 the gripping portion 32 with their hands and pulls it up, moving the movable plate 12, side plate 30, and associated components from the opening 53 to the inside of the luggage compartment 51 (FIGS. 5(A)(B)). Then, the above-mentioned placing step to the raising step are repeated as necessary. It is also possible to reverse the placing step and the removing step to move the transported item from the outside of the luggage compartment 52 to the inside of the luggage compartment 51.

[0047] Next, as a storage step, the spring-up plate 35 is rotated upward from the state shown in FIGS. 5(A) and (B) and fixed with the spring-up plate fixing device 36 (FIGS. 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, 23b and the side plate 30 may be fixed to the fixed plate 11 or the like by a fixing mechanism (not shown) or the like so that the link mechanisms 20, 21, etc. do not move due to vibrations while the vehicle 50 is traveling, etc.

[0048] As described above, the vehicle lifting device 1 of this embodiment can move an object from the luggage compartment inside 51, which has a height difference, 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 object to a lower position.

[0049] In addition, by disposing the links 22a, 22b, 23a, and 23b separately on the front and back of the fixed plate 11 and the movable plate 12, it is possible to move the movable plate 12 and the like to near the dead center. Furthermore, by changing the positions of the dead centers of the left and right link mechanisms 20 and 21, it is possible to prevent abnormal operations such as the left and right links 22a, 22b, 23a, and 23b rotating in the opposite directions.

[0050] In addition, elongated plate materials are used for the fixed plate 11, movable plate 12, side plate 30, and other components, thereby reducing the depth dimension 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 the side plate 30 are partially overlapping in a side view. Furthermore, the link mechanisms 20, 21 are also positioned near their dead centers, and are configured so that the links partially overlap 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, thereby making effective use of the limited luggage compartment space.

[0051] The vehicle lifting device and the method of using the vehicle lifting device described above are merely examples of the present invention, and the configuration can be appropriately modified without departing from the spirit of the invention. For example, the side plates, the top plate, and the bottom plate can be integrally configured to have a rectangular shape with rounded corners when viewed from the front or other shapes.
