Description

  The present invention relates to a box-type pallet having a door panel that can be freely opened and closed, and more particularly to a locking means for the door panel.

  As a box-type pallet provided with a door panel, as disclosed in Patent Document 1, it is provided with a door panel that can be freely opened and closed, and a locking means that locks the door panel in a closed state. The side wall panel side locked portion adjacent to the locked portion and a locking member that can be freely engaged with and disengaged from the locked portion. The locking member is horizontally moved and rotated on a support portion provided on the door panel side. A lock pin that is supported by the lock pin, and a handle portion that is connected to the lock pin. The lock member has a lock position where the lock pin engages with the locked portion, and the handle portion. Is provided with a lock holding contact portion that prevents movement of the lock pin in the unlocking direction adjacent to the contacted portion on the door panel side when in a hanging position along the outside of the door panel. By rotating upward from the hanging position Constructed box-pallet is known as the abutment for the lock hold is unlocked away from the abutted portion.

As a method of using this type of box-type pallet, there is known a method of using an inner bag set in the pallet and storing roses such as grains in the inner bag. When using the pallet in such a way, when taking out the contents of the inner bag, the pallet is picked up by the reversing machine provided in the forklift and turned upside down, and the contents are opened from the mouth of the inner bag facing downward. When the pallet is turned upside down, the handle that holds the lock pin in the locked position is flipped upside down by gravity against the pallet. The lock pin is unlocked. In this state, the lock pin slides in the unlocking direction due to vibration when handling the pallet, and the door panel may be unlocked unexpectedly. Therefore, the door panel may be opened during the work of lifting the pallet with a forklift and turning it over, or when the pallet is returned to the upright position with the door panel unlocked. An abnormal situation with danger will occur. As a means to solve such problems, as described in Patent Document 2, the handle portion is biased and held in a suspended position with respect to the pallet by a spring, and the handle portion is unlocked even if the pallet is turned upside down. It is known to be configured so as not to rotate to a posture.

The lock member 21 includes a supported lock pin 21 and a handle 22 connected to the lock pin 21, and the lock member 14 is in a lock position where the lock pin 21 is engaged with the locked portion 15. The grip portion 22 extends along the outside of the door panel 5. Lock holding contact portions (25, 29) that prevent the lock pin 21 from moving in the unlocking direction are provided adjacent to the contact portions (26, 30) on the door panel 5 side in the hanging position. The lock holding contact portions (25, 29) are moved outward from the contacted portions (26, 30) to be unlocked by rotating the handle portion 22 upward from the hanging position. is configured, the prior SL lock holding abutment (25, 29) and said abutted portion (26, 30), the handle portion 22 of the locking member 14, until almost directly above said hanging position In the box-type pallet configured to allow movement of the lock pin 21 in the lock position in the unlocking direction only when the angle is at an intermediate specific angle θ in the vertical rotation range between the rotated standing posture ,
The lock holding contact portion includes a first contact portion 25 and a second contact portion 29, and the contacted portion is a first contacted portion that acts on the first contact portion 25. Portion 26 and a second abutted portion 30 acting on the second abutting portion 29, and when the handle portion 22 is in the hanging position, the first abutting portion 25 and the first abutted portion In the state where the lock pin 21 at the lock position is prevented from moving in the unlocking direction by contact with the contact portion 26 and the handle portion 22 is rotated upward to an angle other than the intermediate specific angle θ, the first By the contact between the second contact portion 29 and the second contacted portion 30, the lock pin located at the lock position is prevented from moving in the unlocking direction .

Furthermore, in the present invention, the handle portion 22 is constituted by a U-shaped handle member 23 fixed to the lock pin 21 at the left and right longitudinal axis portions 24a and 24b, and the first abutting portion 25 is formed of the U-shaped handle portion 25. wherein one side of the vertical axis portion 24b of the shaped handle member 23 is constituted by a free end portion extending on the opposite side of the lock pin 21, the first abutted portion 26, when the locking pin 21 is in the locked position It consists of longitudinal wire 20b of the door panel 5 adjacent to the first contact portion 25 to the supporting portion 13 of the door panel 5 side, as well as bending the wire into the gate-shaped, the left and right vertical shaft 16a, the projecting portions 17a projecting in an arc shape outwardly 16b constitute between door panel 5 the supporting hole of the lock pin 21 is composed of a support member 18 which 17b is formed, the second contact The portion 29 is formed from the lock pin 21. Consists of a set has been protrusion, the second abutted portion 30, the projecting portion on one side of the lock pin 21 is the support member 18 adjacent to the second contact portion 30 when in the locked position It is composed of 17a.

In carrying out the present invention having the above-described configuration, specifically, as described in claim 2 , the projecting portion constituting the second contact portion 29 crushes a part of the peripheral surface of the lock pin 21 from both sides. It is desirable to form it by the overhang | projection meat | flesh part extended in the radial direction.

  According to the box-type pallet including the door panel according to the present invention having the above-described configuration, when the door panel locked in the closed position is opened, the handle portion of the lock member is turned upright from the suspended posture. The lock pin is slid in the unlocking direction with the handle while the lock pin is rotated upward to an intermediate specific angle in the vertical rotation range between the posture and the lock pin is detached from the locked portion on the side wall panel side. Just do it. That is, compared with the conventional one, there is an inconvenience that when the door panel is unlocked, the upward rotation angle of the handle portion is regulated to an intermediate specific angle within the rotation range of the handle portion. The lock pin slides in the unlocking direction in an angle other than the intermediate specific angle, for example, in a state in which the handle portion is turned upright in the upside down direction, the lock holding contact portion on the lock member side Because it is blocked by contact with the contacted part on the door panel side, when the inner bag is set on this box-type pallet and used for transporting and storing loose items, the contents are taken out from the inner bag. When the pallet is inverted upside down, the lock pin is not unlocked even if the handle portion rotates to the upside down posture (standing position when viewed from the pallet side) due to gravity.

  Therefore, the box-type pallet according to the present invention is caused by turning the pallet upside down in order to take out the contents from the inner bag even when the inner bag is set and used for transporting and storing roses. Then, at that time or thereafter, a dangerous abnormal situation that the door panel opens unexpectedly does not occur, and can be used safely. In addition, it does not require a biasing means such as a spring or an alternative rubber belt, and can be implemented at a relatively low cost. In addition, extra force is required to rotate the handle to unlock the door panel. There is no inconvenience.

Further , according to the configuration of the present invention , since the first contact portion and the first contacted portion can use a conventionally known configuration as described above, the handle portion is provided on the conventional ready-made box-type pallet. By adding a second contact portion and a second contacted portion that prevent the lock pin from moving in the unlocking direction when it is within the range from the standing posture to the intermediate specific angle , the above-described effects are obtained. The present invention can be expected. Therefore, the improvement of the conventional ready-made box pallet can be performed easily and easily, and the assets can be used effectively.

Furthermore , according to the configuration of the present invention , the second contacted portion can be configured by utilizing the support portion of the lock member (lock pin) on the door panel side provided in the conventionally known box-type pallet as it is. As the contact portion, it is only necessary to project the protrusion on the lock pin, so that the improvement of the conventional ready-made box-type pallet can be performed more easily and easily.

Further , according to the configuration of the second aspect, the second abutting portion (projecting portion) of the lock pin can also be integrally formed by crushing the lock pin, so that another member can be locked to provide the projecting portion. Compared with the case of attaching to a pin, it can be implemented at low cost.

  First, a specific structure of a conventionally known box-type pallet will be described with reference to the accompanying drawings showing specific embodiments of the present invention. In FIG. The left and right side wall panels 2 and 3 and the back panel 4 are erected, and the door panel 5 is erected on the remaining one side. Specifically, the back panel 4 is attached so as to be foldable so that the horizontal lower side of the back panel 4 overlaps the back side of the loading platform 1 via a coil hinge on the loading platform 1. 3, the vertical rear side is foldably attached to the left and right sides of the back panel 4 so as to overlap the inside of the back panel 4 via coil hinges 6 and 7, and the door panel 5 is folded inward. The lower half 5A is attached to the position where the lower horizontal side is close to the front side of the loading platform 1 via the coil hinge 8 so as to be openable and closable, and the coil hinge is connected to the horizontal upper side of the lower half 5A of the door panel. 9 and a lower half portion 5B attached to be openable in the front-rear direction. Therefore, in a state where the left and right side wall panels 2 and 3 are folded so as to overlap the inside of the back panel 4, the back panel 4 is folded so as to be superimposed on the loading platform 1, and the door panel 5 is folded so as to be superimposed thereon. be able to.

  In addition, below the four corners of the loading platform 1, a fork insertion space for a forklift is formed and a leg 10 for stacking the same pallet is projected downward. Each panel 2 to 5 has a mesh structure in which longitudinal wires (steel wires) and transverse wires (steel wires) are arranged in a grid pattern, and both wires are fixed to each other at each intersection. Are well known in the art.

  Locking means 11A and 11B are disposed at two locations near the upper end of both the left and right vertical sides of the lower half 5A of the door panel 5, and at two locations near the upper end of the vertical left and right sides of the upper half 5B of the door panel 5. Are provided with locking means 12A, 12B. Since the locking means 11A, 12A on one of the left and right sides and the locking means 11B, 12B on the other of the left and right are configured symmetrically and the basic structure is the same, the upper half of the door panel will be described below. The configuration of each locking means will be described taking the locking means 12A on the left side of the portion 5B as an example.

  As shown in FIGS. 2 and 3, the locking means 12 </ b> A includes a support portion 13 attached to the outside of the upper half 5 </ b> B of the door panel, a lock member 14 supported by the support portion 13, and the vertical of the side wall panel 2. It is comprised from the to-be-latched part 15 protruding ahead from the front side.

  The support portion 13 bends one wire (steel wire) into a gate shape, and protrudes outward in an arc shape at the upper end portion connected to the horizontal axis portion 16c of the left and right vertical axis portions 16a and 16b. The projecting portions 17a and 17b use a support member 18 which is bent. The support member 18 has both left and right longitudinal axis portions 16a and 16b of the lateral wires 19a and 19b inside the door panel upper half 5B. The horizontal axis portion 16c is attached to the outside of the door panel upper half portion 5B so as to overlap with the vertical wires 20a and 20b outside the door panel upper half portion 5B. The lock member 14 is inserted in the horizontal direction between the protrusions 17a and 17b in the left and right vertical axis portions 16a and 16b of the support member 18 and the vertical wires 20a to 20e outside the door panel upper half 5B. The lock pin 21 and a handle portion 22 connected to the lock pin 21 are configured. The handle portion 22 uses a handle member 23 obtained by bending one wire (steel wire) into a U-shape, and the handle member 23 is connected to the free end portions of the left and right longitudinal axis portions 24a and 24b. The left and right longitudinal axis portions 16a and 16b of the support member 18 are configured to overlap each other so as to cross the inside of the lock pin 21 (on the door panel upper half 5B side) and to be fixed to each other. The locked portion 15 is obtained by bending a single wire (steel wire) into a U shape, and is attached to the vertical front side of the side wall panel 2 so as to protrude forward. On the door panel located between the left and right vertical axis portions 24a and 24b of the handle member 23 and the left and right vertical axis portions 16a and 16b of the support member 18 The positional relationship between the half 5B and the longitudinal wires 20a and 20b is set so that the locking means 12A can function as follows.

  As shown in FIGS. 1 to 3, by closing the door panel 5, the left and right sides of the door panel upper half 5 </ b> B are overlapped with the vertical front side of the side wall panel 2, as shown in FIGS. 2 and 3. Thus, the locked portion 15 on the side wall panel 2 side projects outwardly between the longitudinal wires 20c and 20d of the door panel upper half 5B at the same level as the lock pin 21. In this state, when the door panel upper half 5B is locked by the locking means 12A, the handle member 23 is rotated upward and forward with the lock pin 21 as a rotation axis, and both left and right vertical axis portions 24a of the handle member 23 are In the state where the free end portion of 24b is rotated to the outer position of the lock pin 21 that does not interfere with the longitudinal wires 20a and 20b of the upper half 5B of the door panel, the lock pin 21 is covered using the handle member 23. By moving the locking pin 21 toward the locking portion 15 in the locking direction, the front end portion of the lock pin 21 is penetrated in the horizontal direction in the locked portion 15 outside the upper half 5B of the door panel. Then, the free end portion of the left vertical axis portion 24a of the handle member 23 and the left vertical axis portion 16a (including the protruding portion 17a) of the support member 18 are adjacent to each other, and the movement of the lock pin 21 in the locking direction is restricted. In this state, the handle member 23 is rotated downward, the horizontal shaft portion 24c of the handle member 23 abuts on the vertical wire 20a of the upper half portion 5B of the door panel, and both the left and right vertical axis portions 24a and 24b of the handle member 23 are in contact. The handle member 23 is switched to a hanging posture in which the free end portion of the pin returns to the inner position of the lock pin 21. At this time, the free end portion of the right vertical axis 24b of the handle member 23 is adjacent to the left side of the vertical wire 20b of the door panel upper half 5B, and the lock pin 21 that has reached the lock position moves in the unlocking direction. This is prevented by the contact between the free end portion of the right vertical axis portion 24b of the handle member 23 and the vertical wire 20b of the upper half portion 5B of the door panel, and the lock pin 21 is held in the locked position. That is, the free end portion of the right vertical axis portion 24b of the handle member 23 constitutes the first holding portion 25 for holding the lock pin 21 in the lock position, and the vertical wire of the upper half 5B of the door panel. 20b constitutes the first abutted portion 26 on the door panel upper half 5B side that acts on the first abutting portion 25.

  When opening the door panel 5 (the upper half of the door panel 5B), the handle member 23 in the above hanging position is rotated upward and the free ends of the left and right vertical axes 24a and 24b are moved to the upper half of the door panel. The lock pin 21 is turned to the unlocked state by rotating to the outer position of the lock pin 21 that does not interfere with the longitudinal wires 20a and 20b of the portion 5B, and then the grip member 23 is used to move the lock pin 21 from the locked portion 15 to the tip portion. Move in the unlocking direction to release. The door panel 5 (door panel upper half 5B) can now be moved forward, but the free end of the left vertical axis 24a of the handle member 23 moves the vertical wire 20a of the door panel upper half 5B to the right. When the handle member 23 is returned to the original hanging position at a position where the handle member 23 is overcome, the lock pin 21 is unexpectedly slid in the locking direction. The free end portion of the left vertical axis 24a of the handle member 23 is placed on the door panel. This can be prevented by contacting the longitudinal wire 20a of the half 5B. That is, the free end portion of the left vertical axis portion 24a of the handle member 23 constitutes a third contact portion 27 that holds the lock pin 21 in the unlocked position, and the vertical wire 20a of the door panel upper half 5B is The third abutted portion 28 on the door panel upper half 5B side that acts on the third abutting portion 27 is configured.

  In the locking means 12A having the conventionally well-known configuration as described above, in this embodiment according to the present invention, as shown in FIGS. 4 and 5, the lock pin 21 is provided with a second abutting portion 29 for holding the lock. Is done. That is, as shown in FIG. 2, when the lock pin 21 is in the locked position and is held in the locked position by the handle member 23 in the suspended position, the protrusion 17a of the left vertical axis portion 16a of the support member 18 On the other hand, the free end portions of the left and right vertical axis portions 24a and 24b are adjacent to the side of the locked portion 15 with which the tip end portion of the lock pin 21 is engaged and viewed from the horizontal axis portion 24c side of the handle member 23 (first end). A second abutting portion 29 projecting from the lock pin 21 protrudes substantially in the same direction as the first and third abutting portions 25, 27). The second abutting portion 29 is composed of a projecting portion that protrudes in the radial direction from the lock pin 21, and the projecting portion squeezes a part of the peripheral surface of the lock pin 21 from both sides to project into a substantially semicircular shape. It is formed by the overhanging meat part. The overhang amount and thickness of the second contact portion 29 are set so as to function as follows.

  That is, the presence of the second contact portion 29 described above causes the handle member 23 to slide the lock pin 21 in the lock position where the tip end portion engages with the locked portion 15 on the side wall panel 2 side in the unlocking direction. When the handle member 23 is simply rotated up to the upright posture as shown by the phantom line in FIG. 4B, the left and right longitudinal axis portions 24a and 24b of the handle member 23 are rotated. The free end portions (first and third contact portions 25 and 27) move to the outer position of the lock pin 21 that does not interfere with the longitudinal wires 20a and 20b of the door panel upper half 5B. Is inclined outwardly downward, and its tip end portion overlaps with the protruding portion 17a of the left vertical axis portion 16a of the support member 18 when viewed from the side (when viewed from the axial direction of the lock pin 21). The handle member 23 Even if the pin 21 is lifted and the position of the lock pin 21 is raised within the range of play in the protrusions 17a and 17b, the protrusion 17a and the second contact portion 29 interfere with each other to unlock the lock pin 21. Cannot slide in the direction. In other words, in this embodiment, the protruding portion 17a of the left vertical axis portion 16a of the support member 18 contacts the second contact portion 29 on the lock pin 21 side to hold the lock pin 21 in the locked position. The contact portion 30 is configured.

  Accordingly, when the handle member 23 is rotated forward and upward in order to slide the lock pin 21 in the lock position in the unlocking direction, the lock pin 21 is lifted by the handle member 23 as shown by a solid line in FIG. 4B. Thus, in a side view (when viewed from the axial direction of the lock pin 21), the first contact portion (the free end portion of the right vertical axis portion 24b) 25 on the handle member 23 side is the first contacted portion on the door panel side. The second abutting portion 29 on the lock pin 21 side is oriented so as not to overlap with the portion 26 (the vertical wire 20b of the door panel upper half 5B), and the second abutted portion 30 on the door panel side (in the support member 18). The handle member 23 is rotated forward and upward to an angle that does not overlap with the protruding portion 17a) of the left vertical axis portion 16a, that is, an intermediate specific angle θ between the suspended posture and the upright inverted posture. In this state, by moving the lock pin 21 in the unlocking direction via the handle member 23, interference or lock between the first contact portion 25 on the handle member 23 side and the first contacted portion 26 on the door panel side. The lock pin 21 is moved in the unlocking direction without receiving interference between the second contact portion 29 on the pin 21 side and the second contacted portion 30 on the door panel side, and the door panel upper half 5B is closed. Can be unlocked and the door panel upper half 5B can be rotated.

  It has been described that the two conditions of lifting the lock pin 21 by the handle member 23 and rotating the handle member 23 to the upper middle specific angle θ are necessary. The two abutting portions 29 are constituted by semicircular protrusions, and the protruding portion 17a of the left longitudinal axis portion 16a of the support member 18 constituting the second abutted portion 30 is constituted by a round bar-like wire rod. Therefore, in actuality, even if the lock pin 21 is moved in the unlocking direction by the handle member 23 rotated upward to the intermediate specific angle θ without lifting the lock pin 21 by the handle member 23, Since the peripheral surface of the contact portion 29 rides on the peripheral surface of the second contacted portion 30 and can pass while pushing up the lock pin 21, it is possible to move the lock pin 21 in the unlocking direction without any problem.

  Of course, in this embodiment, since the inside of the protrusion 17a (second contacted portion 30) of the left vertical axis 16a of the support member 18 is open, the handle member 23 is rotated to the intermediate specific angle θ. If the second contact portion 29 is protruded from the lock pin 21 so that the first contact portion 29 does not overlap the protruding portion 17a when viewed from the side, Without lifting 21, the lock pin 21 is moved in the unlocking direction by the handle member 23 that has been rotated forward and upward to the intermediate specific angle θ, and the second abutting portion 29 becomes the protruding portion 17 a (second abutted portion). 30), after that, the handle member 23 can be rotated further upward from the intermediate specific angle θ to, for example, a vertically inverted standing posture, and the lock pin 21 can be further moved in the unlocking direction. .

  According to the box-type pallet according to the embodiment of the present invention having the above configuration, even when the inner bag is set on the box-type pallet and used for transporting and storing roses, the contents are taken out from the inner bag. When the pallet is turned upside down, as shown in FIG. 6, the handle member 23 is pivoted downward due to gravity and hangs down, and in the play space in the left and right projecting portions 17 a and 17 b of the support member 18. 4B, the state shown by the phantom line in FIG. 4B, that is, the same state as the state in which the handle member 23 is rotated up to the standing position and the lock pin 21 is lifted up, Even if the first contact portion 25 on the member 23 side and the first contacted portion 26 on the door panel side no longer interfere with each other and the lock pin 21 cannot be held in the locked position, the lock pin 21 side Second contact 29 and the second contacted portion 30 (projecting portion 17a) on the support member 18 side interfere with each other to hold the lock pin 21 in the locked position, so that the lock pin 21 is locked unexpectedly due to vibration or the like. The fear of moving in the release direction and opening the upper half 5B of the door panel is eliminated.
