Description
[Technical Field]
[0001] The present invention relates to a luggage carrier that divides the interior of a box-shaped loading platform such as a truck, trailer, or container into upper and lower sections to effectively utilize the interior space. [Background technology]
[0002] Conventionally, many cargo loading platforms have been proposed that divide the box-shaped loading platform of a truck, trailer, container, or the like into upper and lower sections with a table base, and that have foldable front and rear legs (see Patent Documents 1 and 2). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 4898189 [Patent Document 2] Patent No. 3689712 Summary of the Invention [Problem to be solved by the invention]
[0004] Recently, there has been a trend toward increasing overall lengths of box-shaped loading platforms for trucks, trailers, and the like, and there is a demand for longer loading platforms. In the structure in which the luggage loading platform described in Patent Documents 1 and 2 is simply lengthened (for example, by 4,500 mm or more), when a heavy load is placed on it, the area near the center in the longitudinal direction bends significantly, causing problems such as damage to the items (luggage) loaded below the platform. [Means for solving the problem]
[0005] Therefore, the present invention provides a luggage loading platform that comprises a table body that divides the internal space of a box-shaped loading platform of a truck or the like into upper and lower sections over approximately the entire length, and front and rear legs that are provided at the front and rear edges of the table body and can be freely switched between a vertically hanging position and a horizontally folded position; and support legs are detachably arranged on each of the left and right vertical beams of the table body, either at a central location in the fore-and-aft direction or at two separate locations in the fore-and-aft direction.
[0006] The vertical beam is a square pipe with a vertically long rectangular cross section; the support legs have a vertical beam support portion at their upper ends that has a J-shaped or U-shaped cross section and supports the square pipe-shaped vertical beam from below. In addition, a channel-shaped insertion slit forming member having a shallow planar view and a strip piece portion with a screw hole in the center and short leg portions connected to both ends thereof is fixed to the inner vertical surface of the square tube-shaped vertical beam; an insertion slit is formed between the strip piece portion of the insertion slit forming member and the inner vertical surface; a part of the vertical beam receiving portion at the upper end of the support leg is inserted into the slit from below; and a locking bolt with a manual rotation knob is screwed into the screw hole of the strip piece portion to fix the vertical beam receiving portion at the upper end of the support leg.
[0007] In addition, the vertical beam receiving portion, which has a J-shaped or U-shaped cross section, has a recessed portion formed therein to prevent it from coming off; when the tip of the bolt is pressed into the recessed portion, the support leg is prevented from coming off. The vertical beam receiving portion has a J-shaped cross section consisting of a horizontal bottom piece, a vertical long piece, and a vertical short piece, and the vertical long piece is configured to be freely inserted into the insertion slit from below; and the thickness of the vertical long piece is T. 15 If the gap dimension of the insertion slit is W, then: 1.2 T 15 ≦W≦2.0 ·T 15 It was set as follows.
[0008] In addition, a chamfer is formed at the lower edge of the inner surface side where the strip piece portion of the slit forming member forms the insertion slit, to guide the vertical long piece portion being inserted from below. Furthermore, the support leg is configured so that its lower end is kept in an inclined position outside the side of the box-shaped loading platform of a truck or the like, and the vertical long piece is inserted into the insertion slit from below, and when the final insertion is completed, the support leg is in a vertical position. Further, a roller that rolls in contact with the floor surface of the truck bed when the support leg is in the inclined position is attached to the lower end of the support leg. [Effects of the Invention]
[0009] According to the present invention, the central region of the longitudinal beam of a long table body can be prevented from bending significantly by using a simple support leg, which allows relatively heavy loads to be placed on the top surface of the table body while preventing damage to the load placed in the space below the table body. Moreover, the support legs can be easily attached when the table body is installed in a gate-like configuration using the front and rear legs. When storing or removing luggage in the space D below the table body, the support legs can be easily detached so that they do not interfere with loading or unloading luggage.

[0011] The present invention will be described in detail below based on the illustrated embodiments. In Figures 1 to 3, 1 is a box-shaped loading platform of a truck 2, and a luggage loading platform 20 having a table body 5 that divides the internal space 3 of the box-shaped loading platform 1 into upper and lower spaces at approximately half the height is provided.
[0012] Front legs 8 and rear legs 9 are pivotally attached to the front edge 6 and rear edge 7 of the table body 5 . The front legs 8 and rear legs 9 can be swung in a vertically hanging position Sv as shown in Figs. 1 and 2, or in a horizontally folded position Sv by swinging them in the direction of arrow M in Fig. 2. H The horizontal folding position S H In this case, the table body 5 is disposed close to the loading platform floor surface 4 in FIG. 1 (not shown), and luggage can be loaded up to the full height of the internal space 3.
[0013] Specifically, a support leg 10 is detachably attached to each of the left and right vertical beams 5A, 5A of the table body 5 at one central location in the front-to-rear direction (in the embodiment of FIG. 2). Alternatively, in the embodiment shown in FIG. 1, support legs 10, 10 are detachably disposed on each of the vertical beams 5A, 5A at two locations separated in the front-rear direction N1.
[0014] Next, as shown in Figures 4 to 9, the vertical beam 5A has a rectangular pipe cross section that is elongated vertically. The support leg 10 has a vertical beam support portion 15 at its upper end that has a J-shaped or U-shaped cross section and supports the square pipe-shaped vertical beam 5A from below. (Note that the U-shaped vertical beam support portion 15 is not shown.) In addition, a shock absorbing material 18 such as rubber is fixed to the inner surface of the groove bottom surface 16 of the stringer receiving portion 15.
[0015] 6 to 9, reference numeral 12 denotes a channel-shaped insertion slit forming member having a shallow planar shape and including a strip piece 12A and short leg portions 12B, 12B connected to both ends of the strip piece 12A. The strip piece 12A has a screw hole 13 in the center. The short legs 12B, 12B of the insertion slit forming member 12 are fixed to the inner vertical surface 25 of the square tube type vertical beam 5A by welding or the like, thereby forming the insertion slit S. L is formed as a straight line in plan view.
[0016] Then, a part 15A of the stringer receiving portion 15 at the upper end of the support leg 10 is inserted through the slit S L 9, a locking bolt 22 with a manual rotation knob 21 is inserted from below and screwed into the screw hole 13 of the strip piece portion 12A to fix (prevent removal of) the stringer receiving portion 15 at the upper end of the support leg 10. A coil spring 23 is attached to the locking bolt 22 to prevent the bolt from loosening.
[0017] The stringer support portion 15, which has a J-shaped or U-shaped cross section, is formed with anti-slip recesses 26. Note that in Fig. 4, the recesses 26 are shown as a mesh. That is, as is clear from Fig. 4, the recesses 26 are formed in a band-like shape in the left-right horizontal direction. As shown in Fig. 8, even if the stringer support portion 15 is displaced in the inner space of the slit-forming member 12 (left-right direction in Fig. 8), there is an advantage that the tip of the bolt 22 reliably enters the recess 26 and is locked. In this way, with the tip of the bolt 22 pressed into the recess 26, the support leg 10 can be prevented from accidentally coming out (is prevented from coming out).
[0018] As is clear from Figures 4 to 9, it is desirable that the stringer support portion 15 has a (slightly angular) J-shaped cross section consisting of a horizontal bottom piece 15B, a vertical long piece 15C, and a vertical short piece 15D. In particular, as shown in FIG. 9, the vertical long piece 15C is inserted into the insertion slit S as indicated by the arrow Y. L It can be inserted smoothly inside.
[0019] Furthermore, the thickness dimension of the vertical long piece portion 15C (before the recess portion 26 is formed) is set to T 15 At the same time, the insertion slit S L If the gap dimension is W, the following formula (1) holds: 1.2 T 15 ≦W≦2.0 ·T 15 Formula (1) W is the lower limit (1.2 T 15 ), it becomes difficult to insert (insert) the vertical long piece 15C from below in an inclined position as shown in FIG. Conversely, when W is at the upper limit (2.0 T 15 ) and then the slit S L The vertical long piece 15C tends to swing sideways, making the support leg 10 prone to tipping over.
[0020] Furthermore, the strip plate piece 12A of the slit forming member 12 is inserted into the insertion slit S L A chamfer 32 is cut out at the lower edge of the inner surface 30 forming the groove. That is, as shown in FIG. 9, when the support leg 10 is in an inclined state (with its lower end facing outward), the upper end of the long piece 15C inserted from below is received by the chamfer 32 and guided, so that the long piece 15C is smoothly and quickly inserted into the insertion slit S. L It can be inserted inside.
[0021] In other words, the support leg 10 is inclined in a tilted position K (see FIG. 9) with its lower end 11 facing outward from the side of the box-shaped loading platform 1 of the truck 2, and the long piece portion 15C at the upper end is inserted into the insertion slit S. L When the final insertion is completed, the support leg 10 assumes a vertical position (as shown in FIGS. 6 and 7). Furthermore, a rotating roller 33 is attached to the lower end of the support leg 10, which rolls while in contact with the bed floor surface 4 of the truck 2 in the inclined posture K. In the example shown in Figure 4, this rotating roller 33 is a cylinder that is long in the axial direction.
[0022] 2, 3, and 10 to 12, the underside of the table body 5 is provided with claw receiving members 44 into which the forks of a forklift can be inserted. A pair of these claw receiving members 44 is provided on the underside of each end edge of the table body 5, and the distance between the pair of left and right claw receiving members 44, 44 is the same as the distance between the left and right forks of a commonly used forklift. The positions of the claw receiving members 44 are set so that when forks are inserted into the claw receiving members 44 and the luggage platform 20 is lifted by the forks, the center of gravity of the luggage platform 20 can be supported.
[0023] As shown in detail in Figures 10 to 12, the claw receiving member 44 is formed from a metal plate bent into a U-shape and is attached so as to be rotatable via a pivot 42 to a bracket 41 fixed to the vertical beam 5A of the table main body 5, so that it can be changed between a hanging position perpendicular to the plane of the table main body 5 as shown in Figures 2 and 12, and a parallel folding position as shown in Figures 3, 10 and 11.
[0024] An engagement member 45 is provided to lock the claw receiving member 44 in a folded position parallel to the plane of the table main body 5. This engagement member 45 includes an engagement pin 51 slidably mounted a set amount in an axial hole 43 that penetrates the bracket 41 and the vertical beam 5A, and is elastically urged by a spring 52 toward a pin hole 46 formed in the middle of the U-shaped claw receiving member 44, with its tip engaging with the pin hole 46 to maintain the folded position. A knob 53 at the head of the engagement pin 51 is exposed on the side end surface of the table main body 5 through a window 47 formed in the vertical beam 5A. By grasping this knob 53 with fingers or a tool and pulling it against the elastic force of the spring 52, the engagement pin 51 can be released from the pin hole 46 of the claw receiving member, allowing the claw receiving member 44 to be rotated to a hanging position perpendicular to the plane of the table main body 5 as shown in FIG. 12. In addition, an inclined guide surface 48 is formed around the pin hole 46 so that the tip of the engagement pin 51 can easily engage with the pin hole 46 when the claw receiving member 44 is rotated from the hanging position to the folded position.
[0025] Furthermore, there is provided a holding means 56 for temporarily holding the claw receiving member 44 in a hanging position perpendicular to the plane of the table body 5. In this embodiment, as shown in Figure 10, this holding means 56 is an elastic packing that is interposed around the pivot 42 between the bracket 41 and the claw receiving member 44, and applies a predetermined rotational torque to the claw receiving member 44. 2 and 3, a pair of claw receiving members 44, 44 are disposed near the left and right sides of the support leg 10. The box-shaped loading platform 1 of the present invention includes not only the truck 2 but also trailers, containers, etc.
[0026] As described above in detail, the present invention comprises a table body 5 that divides the internal space 3 of a box-shaped loading platform 1 of a truck 2 or the like into upper and lower parts over substantially the entire length of the table body 5; HIn this luggage platform, which has front legs 8 and rear legs 9 that can be freely switched between the front and rear, support legs 10 are detachably arranged on each of the left and right vertical beams 5A, 5A of the table body 5 at one center position in the fore-and-aft direction or at two separate positions in the fore-and-aft direction N1, so that the top surface of the long table body 5 is flat with no steps at all over the entire length of the box-shaped loading platform 1. Therefore, when two table bodies are arranged one behind the other, steps are created and the loaded luggage may get on the steps and become unstable, but this does not happen at all, and the luggage can always be kept in a stable position regardless of whether it is loaded in the fore-and-aft direction. Furthermore, by arranging the support legs 10 in a detachable manner, when loading or unloading luggage into or from the space D below the table body 5, the (detachable) support legs 10 can be removed, allowing for efficient and rapid work.
[0027] Furthermore, the vertical beams 5A are square pipes with a vertically elongated rectangular cross section; and the support legs 10 have, at their upper ends, vertical beam receiving portions 15 with a J- or U-shaped cross section that support the square pipe-shaped vertical beams 5A from below. Therefore, when loading luggage into the space D below the table body 5, the loading work can be carried out easily and quickly without the support legs 10. After loading is complete, the vertical beam receiving portions 15 with a J- or U-shaped cross section can be smoothly and quickly fitted onto the square pipe-shaped vertical beams 5A from below. Thereafter, luggage can be loaded into the space U above the table body 5.
[0028] In addition, a channel-shaped insertion slit forming member 12 having a shallow planar view and a strip plate piece portion 12A with a screw hole 13 in the center and short leg portions 12B, 12B connected to both ends thereof is fixed to the inner vertical surface 25 of the square tube-shaped vertical beam 5A; an insertion slit S is formed between the strip plate piece portion 12A of the insertion slit forming member 12 and the inner vertical surface 25. L a part 15A of the stringer receiving portion 15 at the upper end of the support leg 10 is formed through the slit S LThe support leg 10 is inserted from below into the vertical beam 5A; a locking bolt 22 with a manual rotation knob 21 is threaded into the threaded hole 13 of the strip piece 12A to secure the stringer support portion 15 at the upper end of the support leg 10. Therefore, the stringer support portion 15 can be inserted smoothly and reliably, as shown in FIG. 9, and then manually rotate the rotation knob 21 to prevent it from coming off. In this way, the support leg 10 can be reliably and quickly secured to the vertical beam 5A. Furthermore, since the rotation knob 21 is disposed on the inner vertical surface 25 of the vertical beam 5A, collision with other components (such as the claws of a forklift) from the side or outside is prevented. In this way, damage to the rotation knob 21 can be prevented. In particular, when loading and unloading cargo into the lower space D, the support leg 10 can be quickly attached (secured) and detached (detached) to the vertical beam 5A, greatly contributing to improved efficiency in loading and unloading cargo.
[0029] In addition, the vertical beam receiving portion 15, which has a J-shaped or U-shaped cross section, is formed with a recessed portion 26 to prevent it from coming off; when the tip of the bolt 22 is pressed into the recessed portion 26, the support leg 10 is prevented from coming off, so that the support leg 10 can be reliably prevented from suddenly coming off downward.
[0030] The vertical beam receiving portion 15 has a J-shaped cross section, which is made up of a horizontal bottom piece 15B, a vertical long piece 15C, and a vertical short piece 15D, and the vertical long piece 15C is inserted into the insertion slit S. L Furthermore, the thickness of the vertical long piece 15C is set to T 15 At the same time, the insertion slit S L If the gap dimension is W, then 1.2 T 15 ≦W≦2.0 ·T 15 Since the support legs 10 are set as above, the lower part of the support legs 10 is tilted outward from the side of the floor surface 4 of the loading platform (see FIG. 9), and the slits S L 9. While inserting the support leg 10 from the inside, the support leg 10 is raised to a vertical position (in the direction of arrow M in FIG. 9). As shown by arrow Y, the long piece portion 15C smoothly and quickly enters the slit S. L It can be inserted into Note that when it is less than the lower limit value (W < 1.2 · T 15 ), it becomes suddenly difficult to insert it into the slit S L . Conversely, when it exceeds the upper limit value (2.0 · T 15 < W), the vertical long piece portion 15C becomes unstable within the slit S L , and the support leg 10 swings excessively.
[0031] Also, at the lower end edge on the inner surface 30 side of the strip plate piece portion 12A of the slit forming member 12 that forms the insertion slit S L , a chamfer 32 for guiding the vertical long piece portion 15C inserted from below is formed by cutting. Therefore, the upper end corner portion of the vertical long piece portion 15C comes into contact with this chamfer 32 and is guided while slidingly contacting, and while swinging in the direction of arrow M in FIG. 9, the support leg 10 can be smoothly inserted into the slit S L .
[0032] Also, the support leg 10 is configured such that its lower end 11 maintains an inclined posture K where it is on the outer side of the side of the box-shaped loading platform 1 such as the truck 2, and the vertical long piece portion 15C is inserted downward into the insertion slit S L . In the final inserted completed state, the support leg 10 is configured to be in a vertical posture. Therefore, in the inclined posture K, as shown by the arrow Y in FIG. 9, it smoothly enters the slit S L , and then enters vertically upward, so that the long piece portion 15C can smoothly, quickly and surely enter the slit S L .
[0033] Also, in the inclined posture K of the support leg 10, a rotating roller 33 that contacts and rolls on the loading platform floor surface 4 of the truck 2 is attached to the lower end of the support leg 10. Therefore, the weight of the support leg 10 is supported by the rotating roller 33 and the loading platform floor surface 4, and the operator can easily and smoothly insert the vertical long piece portion 15C into the slit S L along the locus of the arrow Y shown in FIG. 9 and can support the vertical girder 5A from below at the receiving portion 15.
