Description

  The present invention includes a pallet base having column support members erected at four corners, and a side frame member provided with a support column that is connected to and connected to the column support member, and is used for transporting and storing articles. Folding type pallet with a side frame that connects two struts connected to each other by horizontal members, suitable for supporting and carrying and storing long pallets and both ends of rolls. It belongs to the technical field of pallets with columns, and more specifically, it has a latching member with a simple structure that prevents the side frame material from being inadvertently detached from the column receiving member due to vibration during movement or work. It relates to a pallet with a pillar.

  Conventionally, various types of pallets with pillars having a pallet base in which pillar support members are erected at four corners and side frame members provided with pillars fitted and connected to the pillar support members have been disclosed (for example, patents) Reference 1-6). The pallet with columns is mainly classified into a folding type (for example, see Patent Documents 1 to 5) and an assembly type (for example, see Patent Document 6).

  The folding pallet with pillars is generally a method in which when the load is folded in an empty state after the load is lowered, the column is lifted up slightly to be supported and released after being fixed. However, even if the folding pallet with pillars is not intended for folding work, the support and fixing state of the pillars are supported by reaction when lifting the load during unloading work, vibration during movement, etc. Is released, the support column is inadvertently collapsed and is in a folded state, and there is a risk that it may come into contact with a load or an operator and cause a danger. This problem also applies to the assembly type pallet with pillars. The support and fixed state of the support column is released due to the reaction when lifting the load during unloading work, vibration during movement, etc. Might fall off and come in contact with the load or the worker, causing danger.

  Therefore, in order to solve the problem, as a means for preventing the support and fixing state of the support column from being inadvertently released, (1) providing a hole common to the column receiving member and the support column, and manually operating bolts or pins in the holes Fixing / releasing means by attaching / detaching can be considered. (2) Moreover, the mechanism which restrains the motion (especially rotation) of the standing support | pillar is disclosed (for example, refer patent document 1).

Japanese Patent Laid-Open No. 55-48045 Japanese Utility Model Publication No. 58-46989 Japanese Utility Model Publication No. 7-17726 JP 2003-160133 A JP 2004-35072 A JP 2000-168775 A

  The fixing / releasing means according to (1) has a problem that the operation is troublesome and takes time. In addition, when assembling the pallet, there is a risk of forgetting to attach the bolts or pins.

Of course, there is no possibility that the support column 3a (side frame member 3) will come off carelessly and come into contact with a load or an operator to cause danger. Further, as shown in FIG. 9, the method of releasing the locked state of the locking member 4 with the lever is simple by a series of operations of folding work or dismantling work such as an operator grasping the side frame material 3. In this respect, the operability is excellent.

  In addition, although the said locking member 4 with a lever is provided and implemented in the edge part of the lower horizontal member 3b below among the horizontal members 3b which comprise the said side frame material 3, it is not limited to this. As shown in FIG. 7, it can also be carried out by being provided on the lower side surface of the column 3a. This is preferably performed when the horizontal member 3b is provided above the support column 3a or the like, and it is difficult to provide the horizontal member 3b on the lower surface of the horizontal member 3b. Moreover, as shown in FIG. 8, it can also implement by providing in the corner | angular corner part which the support | pillar 3a and the horizontal member 3b which comprise the said side frame material 3 form. In short, it is preferable that the locking member 4 with a lever is provided at a site that does not interfere with the work of transporting the load.

  In the second embodiment, the columnar pallet 4 according to the first embodiment generates a rotational moment in a direction in which one end portion 4a abuts against the side surface 2a of the column support member 2 due to its own weight. The present invention is characterized by being configured to be hooked on the portion 6 (the invention according to claim 2). In this case, as shown in FIGS. 4 and 6, the locking member 4 with the lever according to the second embodiment can be lowered by bending the end portion 4 a of the locking member 4, for example. Note that the shape is implemented.

  In short, the lever-equipped locking member 4 according to the second embodiment is implemented with a structure in which the other end portion 4c has a counterweight effect. Therefore, as shown in FIG. 6, in the process of inserting the side frame member 3 into the column receiving member 2 and positioning the locking member 4 with the lever to the predetermined depth, one end 4a Due to the counterweight effect, it automatically collides with the latching portion 6 provided on the column receiving member 2 (see symbol X), avoids (see symbol Y), and finally the opening 12 provided at the one end 4a The latch 3 is fitted and latched to prevent the column 3a (side frame member 3) from coming off upward (see also FIG. 5).

  Therefore, according to the columnar pallet 10 according to the second embodiment, the lever-attached locking member 4 that can lock the side frame member 3 to the column receiving member 2 at the same time as the assembly of the pallet is used by its own weight. Therefore, in addition to the same operational effects as those of the first embodiment (see paragraph [0022]), there is no fear of forgetting the locking operation, and it does not take time, so the operability is excellent. Further, the urging means is due to the self-weight action of the lever-equipped locking member 4, and there is no possibility that the urging force is deteriorated.

  10 and 11 show variations of the lever-equipped locking member 4. The locking member 14 with a lever according to the third embodiment is configured such that one end thereof is bent into a hook shape, and the bent engaging portion is engaged with the latching portion 6 (claims). 5). That is, the lever-equipped locking member 14 is different from the lever-equipped locking member 4 according to the first embodiment only in the shape of the tip end of the one end portion 14a.

  Accordingly, the lever-equipped locking member 14 also has a structure in which a thin steel plate is bent at a required angle, and is attached to the lower surface of the horizontal member 3b of the support column 3 by a fixing means such as welding. The intermediate bent portion 4b is suspended and supported so as to be rotatable. The lever-equipped locking member 14 is configured to be latched and locked to the lower end portion of the latching portion 6 of the column receiving member 2 by manual operation.

  Therefore, according to the columnar pallet 10 according to the third embodiment, the lever and the locking member 14 that can be used permanently are used with a simple structure. Play. That is, not only is it excellent in economic efficiency and operability, but also the support column 3a (side frame member 3) is carelessly removed, and there is no risk of contact with a load or an operator. Further, as shown in FIG. 13, the method of releasing the locking state of the locking member 14 with the lever is simple by a series of operations of folding work or dismantling work such as an operator grasping the side frame material 3. In this respect, the operability is excellent.

  In the fourth embodiment, the columnar pallet 14 according to the third embodiment generates a rotation moment in a direction in which one end portion 14a thereof abuts on the side surface 2a of the column support member 2 due to its own weight. The present invention is characterized by being configured to be hooked on the portion 6 (the invention according to claim 2). As shown in FIG. 10, the lever-equipped locking member 14 has its one end portion 4a bent in a hook shape so that it can be lowered over the latching portion 6.

  In short, the lever-equipped locking member 14 according to the fourth embodiment is implemented with a structure in which a counterweight effect is provided at the other end portion 14c as in the second embodiment. Therefore, in the process of inserting the side frame member 3 into the pillar receiving member 2 and positioning the locking member 14 with the lever to a predetermined depth, as shown in FIG. Due to the counterweight effect, it automatically collides with the latching portion 6 provided on the column receiving member 2 (see symbol X), avoids it (see symbol Y), and finally the hook-shaped tip of the latching portion 6 It is hooked to the lower end and prevents the column 3a (side frame member 3) from coming off upward.

  Therefore, according to the columnar pallet 10 according to the fourth embodiment, the lever-attached locking member 4 that can lock the side frame member 3 to the column receiving member 2 at the same time as the assembly of the pallet is used by its own weight. Therefore, the same effects as those of the second embodiment are achieved (see paragraph [0026]).

  14A and 14B show a pivotal portion of a variation of the locking member 4 with lever. The locking member 24 with lever according to the fifth embodiment is an engaging portion with one end bent, and an opening 8 into which the end of the engaging portion can be inserted is formed on the side surface of the column receiving member. It is provided and implemented (invention of claim 6). That is, the lever-equipped locking member 24 according to the illustrated example uses a round bar-like member compared to the lever-equipped locking members 4 and 14 implemented in Example 1 and the like, and bends it to a required angle. The only difference is that it is implemented in the structure.

  Accordingly, the lever-equipped locking member 24 also rotates by supporting the intermediate bent portion 4b on the shaft 5a of the shaft attachment portion 5 attached to the lower surface of the horizontal member 3b of the support column 3 by fixing means such as welding. It is implemented as possible.

Therefore, according to the columnar pallet 10 according to the fifth embodiment, since the locking member 24 with a lever that can be used permanently is used with a simple structure, the column receiving member 2 can be manually operated. When implemented with a configuration in which the opening 8 is inserted and locked, the same effects as the first and third embodiments are achieved (see paragraphs [0022] and [0029]). Further, when the locking member with lever 24 is implemented by its own weight so that a rotational moment is generated in a direction in which the one end 24a abuts on the side surface 2a of the column receiving member 2 (the invention according to claim 2). The same effects as those of the second and fourth embodiments are achieved (see [0026] and [0032]).
