Description

  The present invention relates to an openable / closable gate panel included in various cargo handling pallets.

The lower panel part of the mesh structure in which the openable and closable gate panel is attached to the side of the load support base so that it can be raised and lowered freely, and the mesh structure of the mesh structure that is attached to the upper side of the lower panel part by the hinge A cargo handling pallet composed of an upper panel portion is conventionally known from Patent Document 1 and the like. However, in the conventional gate panel of this kind of cargo handling pallet, as shown in Patent Document 1, the lower side The hinge which connects the upper side of a panel part and the lower side of an upper panel part was comprised from the coil material. That is, since the upper and lower panel portions have a mesh structure, the coil material is rotated along these horizontal wires so as to enclose the horizontal wire on the upper side of the lower panel portion and the horizontal wire on the lower side of the upper panel portion. The hinge can be configured by being externally fitted.

  Therefore, with the conventional method of forming a hinge with a coil material, the hinge structure can be configured without using welding or rivet fixing means in combination, but the inner diameter of the coil material can be kept to a minimum. In addition, since the coil material itself can swing back and forth around the horizontal wire on the lower panel portion side, as a result, the horizontal wire on the upper panel portion side is relatively back and forth relative to the horizontal wire material on the lower panel portion side. Since the movement cannot be prevented, the horizontal wire on the upper panel portion side may fall either on the inside or outside from the horizontal wire on the lower panel portion side, and the smooth opening / closing operation of the upper panel portion may not be possible. In order to solve this problem, conventionally, the horizontal wires on the upper side of the lower panel portion are arranged in two front and rear rows so that the upper end of each vertical wire is sandwiched from the front and rear, and the upper side of the lower panel portion is arranged. Attempts have been made to increase the thickness so that there is substantially no allowance for the coil material to swing back and forth around the horizontal wire on the lower panel side. Even if it is possible to prevent the horizontal wire on the side panel portion side from falling to either front or back, it is not possible to reduce backlash in the front-rear direction of the lower side of the upper panel portion. In addition, since the relative movement of the upper and lower panel portions in the axial direction of the coil material cannot be completely suppressed by the coil material, the relative movement of the upper and lower panel portions in the axial direction of the coil material is prevented separately from the coil material. A separate member is also required, and in combination with the fact that the horizontal wires on the upper side of the lower panel portion must be arranged in two rows in the front and rear, the number of used members (material amount) is also large.

  An object of the present invention is to provide a gate panel for a cargo handling pallet capable of solving the conventional problems as described above, and the gate panel for a cargo handling pallet according to claim 1 will be described later. When the reference numeral of the embodiment is attached and shown, the lower panel portion 5a of the mesh structure attached to the side of the load support base 1 so as to be raised and lowered, and the upper side of the lower panel 5a is raised and lowered by the hinge 12. It is a gate panel 5 of a cargo handling pallet composed of a mesh structure upper panel portion 5b that is freely attached, wherein the hinges 12 are arranged at appropriate intervals in the upper side length direction of the lower panel portion 5a. The hinge unit 24A to 24C is composed of a plurality of hinge units 24A to 24C, and each hinge unit 24A to 24C is located between the two adjacent vertical wires 18 of the upper panel unit 5b and below the upper panel unit 5b. The front and rear side plate portions 25a and 25b of the inverted U-shaped plate 25 are connected to the lower wire portion 17c on the lower side of the upper panel portion 5b. It is configured to be fixed to the upper side of the lower panel portion 5a so as to be restricted to a region supported by the horizontal wire 15a on the side.

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the horizontal wire 15a on the upper side of the lower panel portion 5a is the upper end of each vertical wire 16 of the lower panel portion 5a. The inverted U-shaped plate 25 of each hinge unit 24A-24C is made longer at the rear plate portion 25b than the front plate portion 25a, and the lower side of the front plate portion 25a is placed on the lower panel. The left and right sides of the rear plate portion 25b can be fixed to the two adjacent vertical wires 16 of the lower panel portion 5a while being fixed to the outside of the horizontal wire 15a on the upper side of the portion 5a.

  Further, when the configuration described in claim 2 is adopted, as described in claim 3, the inverted U-shaped plate 25 of each hinge unit 24A to 24C is a vertical wire whose left and right sides are the lower panel portion 5a. The lateral width of the portion covering the horizontal wire 17c on the lower side of the upper panel portion 5b can be made narrower than the lower half portion of the rear side plate portion 25b fixed to the rear panel portion 25b.

  According to the gate panel of the cargo handling pallet according to the first aspect of the present invention, instead of the conventional long coil material, a plurality of hinges made of inverted U-shaped plates are connected to the upper side of the lower panel portion. The front and rear side plates of the inverted U-shaped plate of each hinge unit are connected to the lower side of the upper panel with the horizontal wire on the upper side of the lower panel. In this case, the lower side of the upper panel part is substantially free from back-and-forth movement relative to the upper side of the lower panel part. It is possible to reliably prevent a situation where the upper side of the part falls into either the inside or outside, and to smoothly open and close the upper panel part at all times. In addition, the inverted U-shaped plate of each hinge unit is fitted between two adjacent vertical wires of the upper panel portion, thereby preventing large play in the lateral direction of the upper panel portion relative to the lower panel portion. Therefore, a separate member for preventing the relative movement of the upper and lower panel portions in the horizontal direction is unnecessary.

  Furthermore, since the position of the horizontal wire on the lower side of the upper panel portion is restricted to the region supported by the horizontal wire on the upper side of the lower panel portion as described above, It is not necessary to arrange the horizontal wires on the upper side in two rows inside and outside, and the horizontal wires on the upper side of the lower panel portion are arranged outside the upper ends of the vertical wires of the lower panel portion as described in claim 2. It can arrange | position only and can use the material of a lower panel part, and can aim at a cost reduction. In particular, according to the configuration of the second aspect, compared to the case where the front and rear side plates of the inverted U-shaped plate of each hinge unit are abutted and fixed to both the inner and outer sides of one horizontal wire on the lower panel side. In addition, the width between the front and rear side plates of the inverted U-shaped plate can be appropriately expanded from the diameter of the horizontal wire on the upper panel side, so that the upper panel can be opened and closed smoothly and lightly and smoothly. The front and rear side plate portions of the plate can be easily fixed to the upper side of the lower panel portion by welding. In this case, according to the structure of Claim 3, although it is easy to adhere the rear side board part of an inverted U-shaped board to two adjacent vertical wires of a lower panel part by welding etc. It is not necessary to cause excessive friction between the two vertical wires on the upper panel side sandwiching the inverted U-shaped plate and the inverted U-shaped plate, and the upper panel portion can be smoothly opened and closed. it can.
