Description

  The present invention relates to a loading platform provided with an enclosure panel surrounding a loading space on the loading platform.

  As this type of loading platform with an enclosure panel, as described in Japanese Patent Application Laid-Open No. 2003-133260, a configuration in which all four enclosure panels rising from four sides of a rectangular loading platform can be removed from the loading platform is known. Since all four enclosure panels can be removed from the loading platform in this way, the loading and unloading work can be performed from the entire circumference of the loading platform, so that the practical effect is enormous, but the detachable described in Patent Document 1 A loading platform equipped with an enclosing panel allows the four panels to be completely independent, with the lower sides of each panel individually engaged with the sides of the loading platform, so that the sides of adjacent panels can be operated. Since it was the structure connected with a required latching means, there existed the following problems.

JP 2001-48169 A

  That is, in the well-known loading platform with an enclosure panel as described above, the loading platform adjacent to this panel is held in a state in which the operator holds the first one panel that is brought into engagement with one side of the loading platform. If the next panel is erected on the side and the two panels arranged in the L-shape are not connected to each other by the locking means, the two panels cannot be stabilized independently. That is, the work of attaching the panel to the side of the cargo bed cannot be easily performed by one worker alone. In addition, all panels require locking means that require operation, and specially shaped locking pieces that cannot be lifted directly above the sides of the loading platform, and under each panel on all sides of the loading platform. The necessity of providing a structure that can be engaged with the locking piece on the side also causes a problem that the cost is increased as a whole.

  The present invention proposes a cargo bed with an enclosure panel that can solve the above-mentioned conventional problems, and the cargo bed with an enclosure panel according to the present invention according to claim 1 is an embodiment described later. In order to make it easy to understand the relationship, the reference numerals used in the description of the embodiment are shown in parentheses, and four enclosure panels (3 to 3) rising from the four sides of the rectangular carrier (1) are shown. 6), the loading platform (1) is an upper side of a frame structure (7) having front-end steel (10a, 11a) parallel to both front and rear sides and depth-direction steel (9) parallel to left and right sides. The mesh structure (8) is combined with a number of vertical wires (13) parallel to the depth direction steel (9) and a number of horizontal wires (14) parallel to the front direction steel (10a, 11a). The horizontal wires (14a) located at the front and rear ends of the mesh structure (8) are positioned at the front and rear ends of the frame structure (7). Depth direction steel material (9) located on the left and right ends of the frame structure (7) is made of a steel material having an open groove on the upper side (9a). Of the four enclosure panels (3-6), the side panels (5, 6) located on the left and right sides overlap the side panels (5, 6) on the rear panel (4) located on the rear side. Are connected to both sides of the rear panel (4) via hinge members (22, 23) so that the rear panel (4) can be folded to the lower side of the rear panel (4) and the lower side of the remaining front panel (3). The mesh structure (8a) passes between the horizontal wire (14a) located at both front and rear ends of the mesh structure (8) and the front-facing steel material (10a, 11a) located at both front and rear ends of the frame structure (7) ( 8) The locking pieces (20, 21) having a substantially L-shaped side surface that can be engaged with the lower side of the horizontal wire (14a) located at the front and rear ends of each panel (3,4) are the length of the lower side of each panel (3,4). Multiple protrusions at appropriate intervals in the vertical direction On the lower side of the panel (5, 6) is a groove in the depth direction steel material (9) located between the horizontal wires (14) of the mesh structure (8) and the left and right ends of the frame structure (7). (9a) Protruding pieces (24) that fit inside are projected, the front side of the side panels (5, 6) and the left and right sides of the front panel (3) are connected to the front panel (3). It is configured to be connected and disengaged by locking means (17a to 18b) for preventing the panel from moving forward.

  When carrying out the present invention, specifically, as described in claim 2, the cargo bed (1) includes four enclosure panels (3 to 6) attached to the cargo bed (1), A low loading area guide (33) can be mounted along the inside of at least three panels. In addition, as described in claim 3, the loading platform (1) has at least three panel mounting positions when four enclosure panels (3 to 6) are removed from the loading platform (1). A loading area guide (35) having a low height can be detachably provided at a position that does not protrude outward.

  When the loading area guide (33, 35) as described above is provided, the loading area guide (33, 35) is a mesh structure (8) of the loading platform (1). Of the horizontal wire (14) and the vertical wire (13) constituting the upper side of the wire (14) parallel to the upper side, and the side of the upper side of the wire (14) in the longitudinal direction Can be arranged in a U-shape. Further, the front-facing steel material (10a, 11a) located at both front and rear ends of the frame structure (7) of the loading platform (1) and the depth-direction steel material (9) located at both right and left ends are both open groove grooves (9a , 39), the detachable load loading area guide (35) penetrates through the mesh structure (8) of the loading platform (1) as described in claim 5 to form a frame structure. A structure provided with positioning pieces (37, 38) for positioning the load-carrying area guide (35) by fitting in the concave grooves (9a, 39) of the steel material of the body (7) can be provided.

  According to the configuration of the present invention described in claim 1, the four panels surrounding the periphery of the cargo bed are divided into three panel groups and one front panel that are connected in a foldable manner. Compared to the case where all the panels are independent, the labor required for handling the removed panel can be reduced. And when this panel is attached to the side of the loading platform, a locking piece having a substantially L-shaped side surface provided on the lower side of the back panel located at the center of the group of three panels is attached to the predetermined side of the loading platform. The protrusions on the lower side of both side panels connected to both sides of the back panel are moved into the groove in the depth direction steel material on both sides of the loading platform by tilting the back panel into a vertical posture. These three panel groups can be self-supported and stabilized in a vertical posture on the three sides of the loading platform simply by fitting them together. Therefore, as in the prior art, with one panel standing on one side of the loading platform held in a vertical position, the adjacent second panel is set up, and both panels are connected by the locking means. Thus, compared to the case where two panels can be made independent for the first time, even one person can perform the initial work when mounting the panel very easily and safely. Then, if the both sides of the front panel that was erected and the both side panels are connected by the locking means provided on the front panel, the enclosure panel that is connected in a rectangular shape and cannot be pulled up from the loading platform is completed. Therefore, the operation of attaching the enclosure panel and the operation of removing the enclosure panel which can be performed in the reverse procedure can be performed more easily than the conventional one.

  In addition, the locking piece having a substantially L-shaped side surface only needs to be provided on the two panels of the back panel and the front panel, and the remaining two side panels constitute a frame structure on the loading platform side. Since the protrusion piece that can be simply fitted into the groove portion of the steel material in the depth direction is sufficient, and the locking means that needs to be operated only needs to be provided on the front panel, the cost on the panel side can be reduced as compared with the conventional one. Furthermore, on the loading platform side, it is only necessary to provide a structure that can engage the locking piece whose side surface shape is substantially L-shaped only on the two sides where the back panel and the front panel stand. Compared to the case where a structure capable of engaging a locking piece having a substantially L-shaped side surface must be provided, the restrictions on the configuration that the loading platform side receives are reduced, and the loading platform side is also configured at low cost. I can do it.

  In addition, when carrying out the loading work with all the enclosure panels removed from the periphery of the loading platform, care must be taken so that no load is applied to the panel mounting position on the side of the loading platform. In particular, when a heavy load is stacked on the loading platform, it is difficult to slide the entire loading load on the loading platform even if interference with the panel is found after the loading operation. However, according to the configuration described in claim 2, even if all the enclosure panels are removed from the periphery of the loading platform, as long as the cargo is loaded into the inside of the loading area guide provided on the loading platform, later It is possible to completely avoid the situation where the panel to be attached interferes with the load and the panel cannot be normally attached. Therefore, loading work can be performed easily and efficiently.

  According to the third aspect of the present invention, even when the load loading area guide is extended outward to the position where it overlaps the panel mounting position, when the panel is mounted, the load loading area guide can be removed to mount the panel. Since it does not get in the way, it can be used efficiently on the loading platform.

  When the load loading area guide is used in combination as described above, according to the configuration of claim 4, the load placed on one side of the loading platform where no load loading area guide is provided. Of the heavy load in such a way that it is slid in a direction parallel to the wire on the upper side of the horizontal wire and vertical wire constituting the mesh structure of the cargo bed, and moved to the opposite side of the cargo bed. Even a load can be easily and reliably loaded into a predetermined loading area.

  Furthermore, according to the structure of Claim 5, when comprising a load-loading area guide so that attachment or detachment is possible, it does not add a special member to the loading platform side, but constitutes the frame structure of the loading platform, the front direction steel material In addition, by simply using grooved steel for the depth direction steel material, the load loading area guide placed on the loading platform can be easily positioned at a predetermined position, and the intended purpose can be achieved easily and inexpensively.

  1 to 4, reference numeral 1 denotes a rectangular loading platform, and a leg 2 is attached in the vicinity of the four corners of the bottom, and the front panel 3, the back panel 4, and both sides so as to surround the upper loading space. Surface panels 5 and 6 are provided. As shown in FIG. 5, the loading platform 1 is obtained by stretching a mesh structure 8 on a frame structure 7.

  The frame structure 7 includes two depth direction steel members 9 at both ends in the left and right front direction, two front side direction steel materials 10a and 10b, two rear side direction steel materials 11a and 11b, and one central front direction. The steel material 12 is connected and integrated, and for all of the steel materials 9 to 12, a groove-shaped material is used in such a direction that the groove portion opens upward. The mesh structure 8 includes a lower vertical wire 13 in the depth direction arranged in parallel at an appropriate interval in the frontage direction, and an upper horizontal wire 14 in the frontage direction arranged in parallel at an appropriate interval in the depth direction on the upper side of the lower vertical wire 13. 7 and 11, both ends of the upper horizontal wire 14 are perpendicular to each depth-direction steel material 9 of the frame structure 7 as shown in FIGS. While intersecting, the lower vertical wire 13 is welded to the frame structure 7 at each intersecting portion in a state where the lower vertical wire 13 intersects each of the front-facing steel members 10a to 12 of the frame structure 7 at a right angle.

  In addition, although the bottom face of all the steel materials 9-12 exists on the same horizontal surface, the upper end height of the front direction steel materials 10a-12 is each linear upper side horizontal wire material which both ends adhere to the upper end of the depth direction steel material 9. 14 and each front direction steel material 10a-12, it has become one step lower than the upper end height of the depth direction steel material 9 so that each lower side vertical wire material 13 may be pinched | interposed. Further, the upper horizontal wire 14a in the front end direction at the front and rear end positions of the front end both ends of the frame structure 7 so as to secure the engaging piece insertion space 15 between the front end steel materials 10a and 11a. 10a, 11a are arranged so as to protrude outward in the front-rear direction, and the lower vertical wire 13a in the depth direction at the left and right end positions is adjacent to the upper end of the outer surface of the depth-direction steel material 9 at the left and right end positions of the frame structure 7. Has been placed.

  Each leg 2 has an inner portion at the upper end fitted to both ends between the two front-side steel members 10a and 10b and to both ends between the two rear-side steel members 11a and 11b, and an outer portion at the upper end. Is attached by welding in contact with the bottom surface of the depth-direction steel material 9, and as shown in FIG. 10, is a conventionally known one provided with an outer stacking groove 2a and an inner grounding portion 2b. .

  As shown in FIGS. 1, 2, and 5, the front panel 3 is configured such that an upper half panel portion 3 b is connected to a lower half panel portion 3 a by a coiled hinge member 16 so as to be opened and closed freely. Each of the upper and lower panel portions 3a and 3b has a mesh structure formed by welding horizontal wires arranged in parallel at appropriate intervals in the vertical direction and vertical wires arranged in parallel at appropriate intervals in the horizontal direction at the intersection. Locking means 17a, 17b and 18a, 18b are attached near the upper left and right end corners of the panel portions 3a, 3b. Each of the locking means 17a to 18b includes a locking rod 19a that can move laterally in the horizontal direction and a lever 19b that operates the locking rod 19a. Further, locking pieces 20 are attached to the lower side of the front panel 3 (the lower side of the lower half panel portion 3a) at appropriate intervals in the length direction of the lower side.

  As shown in FIGS. 4 and 5, the back panel 4 has a mesh structure in which horizontal wires arranged in parallel at appropriate intervals in the vertical direction and vertical wires arranged in parallel at appropriate intervals in the horizontal direction are welded at intersections. In addition, locking pieces 21 are attached to the lower side of the back panel 4 at appropriate intervals in the length direction of the lower side.

  As shown in FIGS. 3 and 5, the side panels 5 and 6 have a symmetrical structure, and intersect horizontal wires arranged in parallel at appropriate intervals in the vertical direction and vertical wires arranged in parallel at appropriate intervals in the horizontal direction. It is of a mesh structure formed by welding at a portion, and is connected to the left and right sides of the back panel 4 by coiled hinge members 22 and 23 so as to be swingable back and forth. On the lower side of each side panel 5, 6, protrusions 24 are provided at two positions in the front and rear, and on the front side of each side panel 5, 6, two upper and lower locking means for the front panel 3 are provided. Locked pieces 25 are provided correspondingly to 17a, 18a and 17b, 18b. These latched pieces 25 are formed by bending a wire rod into a U shape, and the front U-shaped portions projecting horizontally forward from the front sides of the side panels 5 and 6 are connected to the locking means 17a to 17a of the front panel 3. The mesh of the front panel 3 can be projected forward through the laterally outer side position of the locking rod 19a in 18b. In this state, the locking rods 19a of the locking means 17a to 18b are slid outward and inserted horizontally into the tip U-shaped portion of each locked piece 25 outside the front panel 3, The front sides of the side panels 5 and 6 and the left and right sides of the front panel 3 can be connected. The locking means 17a to 18b and the locked piece 25 combined therewith are well known in the art.

  As shown in FIGS. 6, 8, and 9, the locking pieces 20, 21 provided on the front panel 3 and the back panel 4 bend the wire into a U shape, and the lower end U-shaped portion thereof The vertical attachment portion 26a and the bent front end portion 26b are formed to be bent slightly obliquely upward from a right angle, and the bent front end portion 26b has the front panel 3 and the rear panel. The two wire rods of the vertical mounting portion 26a in a direction protruding outward with respect to 4 are placed on the outer sides of the lowermost horizontal wire rod 27a of the front panel 3 and the back panel 4 and the horizontal wire rod 27b immediately above the two wires. It is fixed by welding so that one outer vertical wire 28 of the front panel 3 and the back panel 4 is positioned between the two wires.

  Further, as shown in FIGS. 10 and 11, the protruding pieces 24 provided on the side panels 5 and 6 are formed by bending the wire into a U shape to form an upper half mounting portion 29a and a lower half protruding portion 29b. The upper half attachment portion 29a is connected to the lowermost horizontal wire 30a of each of the side panels 5 and 6 and to the outside of the horizontal wire 30b immediately above the two wires. 29a is fixed by welding so as to be positioned between the two adjacent outer vertical wires 31a, 31b of the side panels 5, 6.

  The enclosure panel composed of the front panel 3, the back panel 4, and the side panels 5, 6 having the above-described configuration is removed from the loading platform 1 during loading and unloading work on the loading platform 1. The removed enclosure panel is rotated on both side panels 5 and 6 around the coiled hinge members 22 and 23 with respect to the back panel 4 so that either the front side or the back side of the back panel 4 is provided. It can fold up so that it may overlap, or it may be piled up with front panel 3 in the state where it folded up so that it might be divided into the front side and back side of back panel 4 and piled up. Thus, after the loading operation, when the enclosure panel is attached to the loading platform 1, the lower side of the rear panel 4 is made to correspond to the rear side of the loading platform 1, and the rear panel 4 is mounted as shown in FIG. In the state where it is inclined so as to incline backward, each locking piece 21 is positioned between the upper horizontal wire 14a of the mesh structure 8 positioned on the rear side of the loading platform 1 and the front opening direction of the frame structure 7 positioned on the inner side. The back panel 4 is erected vertically while being inserted downward into each locking piece insertion space 15 between the steel material 11a. As a result, as shown in FIG. 9, the lowermost horizontal wire 27 a of the back panel 4 is supported on each lower vertical wire 13 in the mesh structure 8 of the loading platform 1. At this time, the position of the rear panel 4 in the front-rear depth direction and the position in the left-right front direction is such that the lower end portion of the vertical mounting portion 26a of each locking piece 21 is fitted in each locking piece insertion space 15 on the loading platform 1 side. The fact that the rear panel 4 is lifted vertically upward from the loading platform 1 means that the bent leading end portion 26b of each locking piece 21 is located on the rear end of the mesh structure 8 on the loading platform 1 side. The contact with the horizontal wire 14a is prevented.

  The both side panels 5 and 6 are deployed in a right-angled front direction with respect to the back panel 4 when attached to the rear side of the bed 1 as described above, whereby the back panel 4 is loaded as described above. 10b, the lower half projections 29b of the projection pieces 24 projecting from the lower sides of the side panels 5, 6 are placed on the loading platform 1 side as shown in FIGS. The mesh structure 8 is fitted between the front and rear two upper horizontal wires 14 in the upper open groove 10a of the depth direction steel material 9 at the left and right ends of the frame structure 7, and the lowermost horizontal of the side panels 5, 6 The wire 30a can be supported on each upper horizontal wire 14 in the mesh structure 8 on the loading platform 1 side. At this time, the left and right horizontal swings of the side panels 5 and 6 with respect to the back panel 4 are such that the lower half projections 29b of the projection pieces 24 are fitted into the recessed grooves 9a of the depth direction steel material 9 of the frame structure 7. It is blocked by doing.

  If the rear panel 4 and the side panels 5 and 6 are installed in a U shape along the rear side and the left and right sides of the loading platform 1 as described above, the front panel 3 is finally placed on the front side of the loading platform 1. Install. The installation method at this time is exactly the same as that of the back panel 4, and each locking piece 20 of the front panel 3 is positioned on the upper horizontal wire 14a of the mesh structure 8 located on the front side of the loading platform 1 and on the inside thereof. The frame structure 7 to be inserted is inserted downward into the engaging piece insertion spaces 15 between the front-end steel members 10a, and the lowermost horizontal wire 27a of the front panel 3 is below each mesh structure 8 of the loading platform 1. It is supported on the vertical wire 13. At this time, the position of the front panel 3 in the front-rear depth direction and the position in the left-right front direction are such that the lower end portion of the vertical mounting portion 26a of each locking piece 20 is fitted in each locking piece insertion space 15 on the loading platform 1 side. The fact that the front panel 3 is lifted vertically upward from the loading platform 1 means that the bent front end portion 26b of each locking piece 20 is located at the front side of the mesh structure 8 on the loading platform 1 side. The contact with the wire 14a is prevented.

  The front panel 3 installed perpendicularly to the front side of the loading platform 1 as described above is in a state where the left and right sides overlap the front side of the front side of the side panels 5, 6. Since each latched piece 25 protrudes forward from the mesh on the left and right sides of the front panel 3, in this state, the latching bar 19a of each latching means 17a-18b on the front panel 3 side is slid outward. Then, the left and right sides of the front panel 3 and the front sides of the side panels 5 and 6 are connected by engaging the locking bar 19a with the respective latched pieces 25 of the side panels 5 and 6. I can do it. As a result, the front panel 3 is also prevented from falling forward.

  By surrounding the load loaded on the loading platform 1 with the surrounding panel composed of the front panel 3, the back panel 4, and the both side panels 5 and 6, the collapse of the load and the falling of the load are covered with the surrounding panel. The loading platform 1 can be conveyed while preventing. When the load is unloaded from the loading platform 1 at the transport destination, the locking rods 19a of the locking means 17a to 18b of the front panel 1 are detached from the locked pieces 25 of the side panels 5 and 6, and the front panel 1 Although the panel 3 can be removed or only the upper half panel portion 3b of the front panel 1 can be opened to the outside, the load can be carried out from the front side of the loading platform 1. The entire enclosure panel can be removed from the loading platform 1 in the reverse procedure, and the cargo can be carried out from the entire periphery of the loading platform 1.

  As described above, when a load is loaded on the bed 1 with the enclosure panel removed, the load is particularly heavy and the entire load is moved on the bed 1 after being stacked on the bed 1 When it is difficult to do so, it is necessary to load the load into the loading area excluding the surrounding panel installation area on the loading platform 1. In this case, since the lower frame structure 7 can be visually recognized through the mesh structure 8 of the loading platform 1, it is estimated from the positions of the depth-direction steel material 9 at the left and right ends of the frame structure 7 and the front-end steel materials 10 a and 11 a at both ends. Although the loading area can be recognized, it is desirable to provide a loading area guide on the loading platform 1.

  The loading area guide 33 shown in FIG. 12 and FIG. 13 is a rod-shaped steel material 34 having an appropriate thickness, such as a wire or strip, along the outer periphery of the loading area on the loading platform 1. Attached to the mesh structure 8 of the loading platform 1 by welding in a rectangular arrangement along the inside of each of the panels 3 to 6 attached to the periphery. In this case, the protruding height of the bar-shaped steel material 34 constituting the loading area guide 33 from the surface of the loading platform 1 is as low as possible within the height range in which the load slid on the loading platform 1 can be reliably received (5 mm). ~ About several Cm) is desirable.

  The loading area guide 33 does not have to be continuous over the entire periphery of the loading platform 1. For example, when the load is slid on the loading platform 1, it is slid in the direction of the upper horizontal wire 14 in direct contact with the load of the mesh structure 8 constituting the surface of the loading platform 1, as shown in FIG. One end in the direction of the upper horizontal wire 14, that is, one side in the left and right front direction on the loading platform 1 is opened without providing the loading area guide 33, and from the side where there is no loading area guide 33. It can also be configured so that a load can be loaded on the loading platform 1 and slid to the opposite side.

  As described above, regardless of the rectangular frame shape or the U-shaped loading area guide, the loading area guide can be configured to be detachable from the loading platform 1. 15 to 17 show an example of a detachable loading area guide. The illustrated loading area guide 35 is obtained by bending positioning a strip-shaped steel material 36 into a rectangular frame shape or a U-shape and attaching positioning pieces 37 and 38 thereto. These positioning pieces 37, 38 are welded to the outer surface of the strip-shaped steel material 36, and the depth direction steel materials 9 in the recessed groove portions 39 of the front-rear and front-end steel materials 10 a, 11 a and the left-right both ends of the frame structure 7 of the loading platform 1. The mesh structure 8 is fitted into the concave groove portion 9a through the mesh, and is in contact with the outer surface of the concave groove portion 39 of the front end direction steel materials 10a and 11a and the outer surface of the concave groove portion 9a of the depth direction steel material 9. The strip-shaped steel material 36 is prevented from moving outward from the loading area. In the illustrated structure, the positioning piece 37 fitted in the groove 39 of the front direction steel members 10a, 11a is positioned on the outer surface of the groove 39 so that the position of the strip-shaped steel material 36 parallel to the front direction steel materials 10a, 11a is aligned. Since it is close, it is composed of a vertical plate material, but the positioning piece 38 fitted in the concave groove portion 9a of the depth direction steel material 9 has a position of the strip-shaped steel material 36 parallel to the depth direction steel material 9 at the concave groove portion 9a. Therefore, the lower end portion 38a is bent outward at the lower end and is in contact with the outer surface of the concave groove portion 9a.

  The loading area guide 35 having the above-described configuration is installed at a predetermined position along the periphery of the loading platform 1 using the positioning pieces 37 and 38 before loading the loading platform 1 and is removed when loading of the loading is completed. Alternatively, the load is removed after the load is lowered from the loading platform 1. However, the loading area guide 35 may be removed by pulling up the loading area guide 35 directly above the loading platform 1. In this case, of course, as described above, the U-shaped guide 35 is easier to remove than the rectangular frame-shaped guide 35. Further, each side of the guide 35 is divided and the guide pieces are connected to each other by a hinge, or each guide piece is connected to a pipe member attached to, for example, the end of one guide piece. It is also possible to make attachment and removal with respect to the loading platform 1 easier by configuring the vertical pins attached to the end portions so as to be freely connected and disconnected, for example, by making them vertically detachable.

  In addition, although the Example which uses the load-loading area guides 33 and 35 of another member was demonstrated, the circumference | surroundings of a load-loading area among the lower vertical wire 13 and the upper horizontal wire 14 which comprise the mesh structure 8 of the loading platform 1 are demonstrated.
