Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deck board disposed in a vehicle such as an automobile, and more particularly to a vehicle deck board whose vertical position can be easily switched between two stages.
[0002]
[Prior art]
Conventionally, a deck board has been arranged at a position higher than the floor of the luggage compartment of the vehicle so that luggage can be loaded on and under the deck board in the luggage compartment to increase the luggage loading space in the luggage compartment. It has been broken.
Japanese Utility Model Laid-Open No. 61-122136 discloses a conventional example of such a deck board. In this conventional example, a structure in which a deck board is placed at a predetermined height position on the floor is shown.
[0003]
[Problems to be solved by the invention]
However, since the above-described conventional example has a structure in which the deck board is placed at a predetermined position on the floor, it is necessary to remove the deck board from the luggage compartment when the deck board is unnecessary. Therefore, there is a disadvantage that the work for that is complicated. In addition, the removed deck board has to be stored in another place.
For this reason, switching between using the deck board and not using it depending on the size and quantity of the luggage loaded in the luggage compartment has caused some inconvenience.
Therefore, the problem to be solved by the present invention is to make it easy to switch the position of the deck board in the vertical direction to two stages by changing the arrangement of the deck board itself arranged in the luggage compartment of the vehicle. is there.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the first invention of the present application is as described in claim 1.
According to the first aspect of the present invention, the deck board is composed of a plate-like first deck board part and a second deck board part, and the first deck board part and the second deck board part can be bent and rotated. It is connected. The base portion of the first deck board portion is pivotally connected to the base member so as to stand up. The first deck board portion and the second deck board portion are in a first position state in which the first deck board portion and the second deck board portion are continuously placed on the base member, and the first deck board portion is in an upright state with respect to the base member. Thus, the second deck board portion can take two position states, ie, a second position state in which the second deck board portion is at a predetermined height position with respect to the base member. According to the first aspect of the present invention, the height position of the deck board in the vertical direction can be switched between two levels by changing the arrangement of the deck board itself. Therefore, there is no inconvenience that the deck board has to be stored elsewhere.
[0005]
Further, the refraction-rotatable connection between the first deck board part and the second deck board part and the upright connection to the base member of the first deck board part are performed using a four-link mechanism, In this four-link mechanism, the second deck board part is forcibly forced in the direction opposite to the above-mentioned upright rotation with respect to the first deck board part in conjunction with the upright rotation of the first deck board part with respect to the base member. A refraction mechanism is incorporated. For this reason, since the second deck board part is forcibly refracted in the direction opposite to the standing rotation when the first deck board part is turned upright, the second position state of the second deck board part is forced. Can be easily operated.
[0009]
Further, when the tip end portion of the second deck board portion is lifted by hand, the first deck board portion and the second deck board portion are directed upward with the base portion of the first deck board portion as a rotation center. Rotate.
[0010]
Then, after a certain degree of rotation, the cam formed on the sixth link member side end portion of the seventh link member starts to push the base portion of the second deck board portion upward. The second deck board portion starts to bend downward with respect to the link member. Therefore, after that, the second deck board part is refracted downward with respect to the first deck board part, so that the first deck board part is erected from the base member, It becomes easy to support the second deck board part by the first deck board part.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a deck board according to an embodiment of the present invention. In FIG. 1, a deck board 10 includes a plate-like first deck board part 11 and a second deck board part 12.
The first deck board part 11 and the second deck board part 12 are in a single plate shape as a whole and are located on the floor 41 of the vehicle 40 (first position state indicated by a solid line), The state in which the second deck board portion 12 is supported by the first deck board portion 11 in a standing state with respect to the floor 41 and is at a predetermined height from the floor 41 (second position indicated by a two-dot chain line). Can be taken. The floor 41 is a base member as used in the present invention. In order to ensure the appearance when the deck board 10 takes the second position state, a carpet or the like is preferably laid on the floor 41.
[0012]
The base portion 11 a of the first deck board portion 11 is rotatably connected so as to be able to stand with respect to the floor 41 of the vehicle 40. This connection is performed at a lower portion of the first four-link mechanism indicated by reference numeral 20 in FIG.
The base portion 12a of the second deck board portion 12 and the tip portion 11b of the first deck board portion 11 are connected so as to be capable of refraction. This connection is performed at an upper portion of the first four-link mechanism 20. Details of the first four-link mechanism 20 will be described later. In the first position state of the deck board 10, the first deck board part 11 and the second deck board part 12 are mounted in a single plate shape, and at this time, both deck board parts 11 are placed. , 12 are placed on the floor 41.
Further, in the second position state, the first deck board part 11 stands up with respect to the floor 41, and the second deck board part 12 is supported by the first deck board part 11 with respect to the floor 41. The position is at a predetermined height.
[0013]
In the second position state, the overhanging portion 12c formed at the front end portion 12b of the second deck board portion 12 is fitted and locked to the engaging portion 43 formed in the wheel house 42 of the right rear wheel. The Here, the overhanging portion 12c is a portion overhanging in the vehicle width direction of the vehicle 40, and in the first position state of the deck board 10 (see paragraph 0011), the rear side of the wheel house 42 of the right rear wheel in the floor 41. In the second position state (see paragraph 0011), it is located on the engaging portion 43 of the wheel house 42 of the right rear wheel.
[0014]
Similarly, the overhang portion 12d can be fitted and locked to an engagement portion (corresponding to the engagement portion 43) of the wheel house of the left rear wheel (not shown). When returning from the second position state to the first position state, the engagement portion is disengaged and the lock is released.
Reference numeral 13 denotes an upper surface of the deck board 10, and reference numeral 14 (see FIG. 3) denotes a lower surface of the deck board 10. The lower surface 14 may be reinforced with a rib (not shown).
[0015]
If the upper surface 13 of the second deck board portion 12 is at the same height as the upper surface of the wheel house 42 in the second position state, it is easier to load the luggage. That is, in the second position state of the deck board 10, compared to the first position state, the deck board 10 becomes wider by the width of the wheel house 42, and the lateral width can be used effectively accordingly. For example, a golf bag or the like can be placed sideways with a space.
Reference numeral 44 denotes a position where the back door of the vehicle 40 is disposed, and reference numeral 45 denotes a side trim of the vehicle 40.
[0016]
FIG. 2 shows the first four-link mechanism 20 of FIG. In FIG. 2, the first four-link mechanism 20 is formed by sequentially connecting a first link member 21, a second link member 22, a third link member 23, and a fourth link member 24 so as to be rotatable.
The shafts 25, 26, 27, and 28 are shafts that pivotably connect the first link member 21 and the second link member 22, respectively, and shafts that pivotally connect the second link member 22 and the third link member 23. , A shaft that rotatably connects the third link member 23 and the fourth link member 24, and a shaft that rotatably connects the fourth link member 24 and the first link member 21.
[0017]
The base 21a of the first link member 21 is fixed to the floor 41 (see FIG. 1) with a bolt or the like (not shown) through the hole 21b of the base 21a. The second link member 22 is fixed to the first deck board portion 11 (see FIG. 1) of the deck board 10. The holes 22 a and 22 b of the second link member 22 are screw holes when the first deck board portion 11 is attached to the second link member 22. The third link member 23 is fixed to the second deck board portion 12 of the deck board 10. The holes 23 a and 23 b of the third link member 23 are screw holes when the second deck board portion 12 is attached to the third link member 23.
As shown in FIG. 1, the first four link mechanisms 20 are attached in a state in which two first four link mechanisms 20 are arranged in parallel to the first deck board portion 11.
[0018]
The connection between the fourth link member 24 and the third link member 23 is performed by fitting the shaft 27 into a long hole 24 a formed at one end of the fourth link member 24. The long hole 24 a is formed as a long hole in the longitudinal direction of the fourth link member 24. The other end of the fourth link member 24 is rotatably connected to the first link member 21 and the shaft 28. Thereby, the connection between the fourth link member 24 and the third link member 23 can be relatively moved in the longitudinal direction by the length of the long hole 24a by the long hole 24a.
In addition, the function of the long hole 24 a can be provided at the other end of the fourth link member 24. In this case, the fitting with the shaft 28 may be a long hole. Further, the function of the long hole 24a can be shared by both the shaft 27 and the shaft 28. In this case, the fitting of both the shaft 27 and the shaft 28 is a long hole.
[0019]
FIG. 3 explains the operation of the first four-link mechanism 20 of FIG. In FIG. 3, the state shown by the solid line is the first position state of the deck board 10 (see paragraph 0011). The process in which the first deck board portion 11 rises with respect to the floor 41 is shown in three stages with a two-dot chain line. A state in which the first four-link mechanism 20 indicated by a two-dot chain line stands upright with respect to the floor 41 is the second position state (see paragraph 0011).
When the front end portion 12b (see FIG. 1) of the second deck board portion 12 is lifted by hand in the first position state, the first deck board portion 11 and the second deck board portion 12 have the shaft 25 attached thereto. It rotates upward as the center of rotation.
[0020]
When the deck board 10 is rotated upward, the positional relationship of the fitting state between the long hole 24a of the fourth link member 24 and the shaft 27 of the third link member 23 is shown in FIG. 3 in the first position state. As shown well, the first deck board part 11 and the second deck board part 12 are continuously moved on the first four-link mechanism 20 by their own weight in a relatively movable position state. In the state of being arranged, they rotate together as a unit.
[0021]
When it is turned upward to some extent, the shaft 27 comes into contact with the right end surface of the long hole 24a as shown in FIG. When rotating further upward from this state, the third link member 23 is pulled by the fourth link member 24, and the third link member 23 rotates in the clockwise direction about the shaft 26 as an axis. It is the figure which showed this rotation state as it is in the middle of rotation seeing in FIG. This turning state gradually makes the second deck board part 12 bend with respect to the first deck board part 11, and facilitates the forward movement of the second deck board part 12. In this operation, the direction of refraction of the second deck board part 12 with respect to the first deck board part 11 is opposite to the direction in which the first deck board part 11 is raised.
[0022]
When the first deck board part 11 is raised with respect to the floor 41 by further rotating, the second deck board part 12 is placed on the floor 41 at the height position of the second link member 22. The second position state is established by being positioned in a substantially parallel state with respect to the second position state. In this state, as described above, the overhanging portion 12 c formed in the second deck board portion 12 is in a state of being engaged with the engaging portion 43 formed in the wheel house 42.
[0023]
The relative movement between the long hole 24a and the shaft 27 is performed by the difference between the arc locus drawn by the long hole 24a and the arc locus drawn by the shaft 28. That is, the arc locus of the long hole 24a is drawn around the axis 28, and the arc locus of the axis 27 is drawn around the axis 25. Since the shaft 28 and the shaft 25 are offset from each other, the arc of the long hole 24a is smaller than the arc of the shaft 27. As a result, the third link member 23 is pulled from the fourth link member 24 when the arc locus drawn by the shaft 27 is outward from the arc locus drawn by the outermost end of the long hole 24a. It rotates in the clockwise direction around the axis.
[0024]
In the embodiment using the first four-link mechanism 20 described above, the first position state and the first position can be changed only by changing the arrangement of the deck board 10 without removing the deck board 10 from the luggage compartment of a vehicle such as an automobile. Two positions (see paragraph 0011) in two position states can be taken.
Further, when the deck board 10 is repositioned from the first position state to the second position state, the first four link mechanism 20 forces the second deck board portion 12 to the first deck board portion 11. Therefore, the forward movement of the second deck board portion 12 can be easily rotated.
[0025]
FIG. 4 shows a second 4-link mechanism 50 which is a modification of the first 4-link mechanism 20 of FIG. In FIG. 4, the second four-link mechanism 50 is obtained by sequentially connecting a fifth link member 51, a sixth link member 52, a seventh link member 53, and an eighth link member 54 so as to be rotatable.
The shafts 55, 56, 57, and 58 are shafts that rotatably connect the fifth link member 51 and the sixth link member 52, respectively, and shafts that rotatably connect the sixth link member 52 and the seventh link member 53. , A shaft that rotatably connects the seventh link member 53 and the eighth link member 54, and a shaft that rotatably connects the eighth link member 54 and the fifth link member 51.
[0026]
The fifth link member 51 corresponds to the first link member 21 (see FIG. 2) and is fixed to the floor 41. The sixth link member 52 corresponds to the second link member 22 (see FIG. 2) and is fixed to the first deck board portion 11 (see FIG. 1) of the deck board 10.
The seventh link member 53 is disposed on the side of the sixth link member 52 and is attached by a shaft 56. The left end portion of the seventh link member 53 as viewed in FIG. Corresponding to the cam 61, a cam receiving surface 62a is formed on the lower surface of the left end portion of the mounting member 62 as viewed in FIG. The attachment member 62 is rotatably attached to the sixth link member 52 by a shaft 63. The attachment member 62 is fixed to the second deck board portion 12. That is, the second deck board portion 12 is rotatably attached to the sixth link member 52.
[0027]
FIG. 5 illustrates the operation of the second 4-link mechanism 50 of FIG. In FIG. 5, the state indicated by the solid line is the first position state of the deck board 10 (see paragraph 0011). The process in which the first deck board portion 11 rises with respect to the floor 41 is shown in three stages with a two-dot chain line. The state in which the second four-link mechanism 50 indicated by the two-dot chain line stands upright with respect to the floor 41 is the second position state of the deck board 10 (see paragraph 0011).
[0028]
In the first position state, when the tip 12b (see FIG. 1) of the second deck board portion 12 is lifted by hand, the first deck board portion 11 and the second deck board portion 12 are In a state of being connected to the second four-link mechanism 50 by its own weight, the shaft 55 is integrally rotated about the rotation center. As the rotation proceeds, the cam 61 pushes the cam receiving surface 62a of the mounting member 62, and the mounting member 62 is forcibly rotated in the clockwise direction as viewed in FIG. By this rotation, the second deck board portion 12 fixed to the attachment member 62 is forcibly refracted with respect to the first deck board portion 11 fixed to the sixth link member 52.
[0029]
The above-described pressing operation of the cam receiving surface 62a of the cam 61 is performed by the seventh link member 53 rotating in the clockwise direction around the shaft 56 as an axis. Then, the clockwise rotation of the seventh link member 53 is performed with the standing rotation of the first deck board portion 11. The operating principle is substantially the same as in the case of the operation shown in FIG. 3, and the shaft 57 is substantially the same as an arc locus drawn around the axis 58, and the axis 57 is drawn as an arc locus around the axis 58. This is due to the difference in the arc trajectory drawn by the axis 56 around the axis 55.
[0030]
According to the above-described modification, the position of the cam receiving surface 62a pressed by the cam 61 is the tip position of the base portion 12a of the second deck board part 12. Therefore, it is effective in operation to press this position and bend and rotate, and the lifting operation force can be reduced. In some cases, it can be operated with one hand.
[0031]
FIG. 6 shows an enlarged VI-VI cross section of FIG. In FIG. 6, in the second position state (see paragraph 0011), the rod-like fixing member 31 provided on the lower surface 14 side of the overhanging portion 12 c engages with the recess 43 a of the engaging portion 43, The protruding portion 12 c is locked to the engaging portion 43. The position adjusting mechanism 30 may be provided at a position indicated by a two-dot chain line in the overhanging portion 12 c, and the fixing member 31 may be inserted into and removed from the position adjusting mechanism 30.
[0032]
In the above embodiment, the deck board has a plate shape, but is not limited thereto, and may be a lattice plate, for example.
[0033]
