Description

Face frame for preventing collapse of cargo relating dolly mounted surface material (side panel).

In a transport cart with a side panel erected on a pallet with wheels, a face material is attached in the side panel to prevent the cargo from falling. In this case, normally, crosspieces in the horizontal direction are installed, and the top and bottom of the face material are fixed to the top and bottom crosspieces (Patent Document 1).
JP2002-19614

  In this case, since the top and bottom of each face material was fixed to the crosspiece, it was necessary to attach and detach one by one, which was convenient when individually replacing damaged face materials, When all face materials are replaced, or when all face materials are removed or all face materials are attached at the time of new production, there is a problem that the operation cannot be simplified.

However, in the present invention, since the face material obtained by connecting the upper face material and the lower face material is attached to the side panel, the above- mentioned problems have been solved.

That is, the present invention is a transport cart characterized by having the following configuration.
(1) on the pallet, the dolly erected a frame-shaped side panel with substantially square,
(2) the side panel, the horizontal reinforcement is disposed in the upper and middle portion and a lower portion,
(3) A mounting plate of an upper face member having a mounting plate at the upper end and a connecting plate at the lower end is attached to the lateral reinforcing material on the upper side of the side panel.
(4) A mounting plate of a lower face member having a connecting plate at the upper end and a mounting plate at the lower end is attached to the lateral reinforcing material on the lower side of the side panel.
(5) The upper face plate connecting plate and the lower face member connecting plate are connected directly or via an intermediate face plate connecting plate having upper and lower ends connecting plates. .
(6) The connecting plates are stacked and locked to connect the respective face materials, and the intermediate reinforcing member is sandwiched between the stacked connecting plates.

  Further, in the above, the transport cart is characterized in that the front and back surfaces of the connected face members are formed flush with each other.

  In the face material of the present invention, since the face material having the connecting plate common to one edge or both sides is connected, the upper and lower surface materials and, if necessary, the intermediate surface material can be used, and the face material can be attached in combination. Therefore, there is an effect that the work can be simplified.

Further, the back surface of the connecting plate having the thickness t ₁ and the back surface of the substrate having the thickness t ₀ are formed to be flush with each other, t ₀ > 2 × t _1, and the tip of the locking means of the connecting plate is connected to the front surface of the substrate Since the position is set so as not to protrude further, if the front surfaces of the connecting plates are overlapped and connected to each other, the connected face members have an effect that both the front and back surfaces can be formed flush. Therefore, even when the load strongly hits the side panel, there is no possibility of damaging the load on the surface of the face material.

Moreover, the lateral reinforcements of the thickness t ₂ of the dolly, the mounting surface material is sandwiched between the connecting plate,
If t ₀ > 2 × t ₁ + t ₂ , there is no risk that the load will hit the lateral reinforcing material, and the face material becomes a cushion, which can further protect the load.

  Further, if the connecting plate is provided with locking means and receiving means, and the receiving means forms an opening into which the locking means can be inserted on the locking side of the locking means, the locking means can be inserted into the opening. Thus, the locking can be guided, so that the work of attaching the face material can be further simplified.

  In addition, even if a part of the face material is damaged, such as when an impact is frequently applied to a part of the face material, only a part of the damaged face material can be easily replaced, so maintenance is easy. Thus, it is possible to eliminate a waste of materials and to form a transport cart with the best face material attached at all times.

  Furthermore, the face material can be easily formed of a non-metallic and soft material such as a resin. In this case, each face frame of the carriage for transportation generally formed of a metal (particularly steel) material is used. Even if it passes, there is no impact sound and the work environment can be improved.

The face material of the present invention is a face material that is attached to the face frames 41, 44, 46, and 59 of the carriage for transportation, is made of a hard resin, and is a face material that can be easily attached and detached by dividing it vertically. 1 to 3 and FIGS. 9 to 11). The face material is
The upper face material 29 (FIGS. 6, 7, 14, and 15) in which the connecting plate 7 is connected to the lower edge of the substrate 1
The lower face material 30 in which the connecting plate 7 is continuously provided on the upper edge of the substrate 1
Intermediate member face material 24 in which connecting plates 7 are continuously provided on both upper and lower edges of the substrate 1 (FIGS. 4, 5, 12, and 13)
And consists of The combination of the upper face material 29 and the lower face material 30 is essential, and the connecting plates 7 of the double face materials 29 and 30 are overlapped with each other to form an integral face material. If the intermediate face material 24 is interposed between the upper face material 29 and the lower face material 30 and the connection plates 7 and 7 are similarly overlapped and connected, the height direction can be arbitrarily set.

The thickness _{t 0} of the substrate 1, the thickness _{t 1} of the connecting plate 7,
t ₀ > 2 × t ₁
As described above, the connecting plate 7 is formed to be thin, and the connecting plate 7 is formed so as not to be thicker than the substrate 1 even if two connecting plates 7 are stacked. Further, the back surface 9 of the connecting plate 7 and the back surface 3 of the substrate 1 are flush with each other, and by forming the locking means 12, 21, etc. on the front surface 8 side of the connecting plate 7, the respective face members 24, 29, 30 are attached. Unevenness generated on the surface when connected in an overlapping manner can be reduced as much as possible (FIGS. 8, 16, and 17).

Further, when the face members 24, 29, 30 are attached to the transporting carriage, the connecting plates 7, 7 are connected with the lateral reinforcing members 53 of the face frames 41, 44, 46, 59 sandwiched therebetween, so that the face frame 41, etc. The face members 24, 29, and 30 attached to the face frame 41 are prevented from being deformed or moved so as to protrude inward or outward of each face frame 41 or the like. In this case, when a t ₂ (the outer diameter in the case of round bar) thickness of the transverse stiffener 53,
t ₀ > 2 × t ₁ + t ₂

[2] Attaching the face materials 24, 29, 30

  Next, a structure in which the face members 24, 29, 30 are attached to the face frames 41, 44, 46, 59 of the transport carriage 67 as a base, that is, the carriage of the present invention will be described.

(1) In the front frame 59, an upper face material 29 and a lower face material 30 are prepared.

(a) First, the mounting plate 33 of the upper face material 29 is overlaid on the lateral reinforcing material (located at the top) 53 of the front frame 59, and the through hole (not shown) of the lateral reinforcing material 53 and the mounting plate 33 are stacked. The mounting holes 36 and 36 are communicated with each other and fixed integrally with screws, pins or the like (FIG. 6). In this state, the surface 8 side of the connecting plate 7 of the upper surface member 39, between the openings 10 and 19 (the part between. Width H ₄ engaging veneer 12 and the opening 19), the transverse reinforcement in the central portion The material 53 is located (FIGS. 8A and 8B).

(b) Subsequently, the surface 8 side of the connecting plate 7 of the lower face member 30 is overlapped with the surface 8 side of the connecting plate 7 of the upper face member 29. With the overlapping connecting plates 7 and 7, one locking protrusion 12 can enter the other opening 19 to guide the locking (FIGS. 8A and 8B). At this time, the lateral reinforcing member 53 at the center portion of the front frame 59 is sandwiched between the engaging protruding plate 12 and the receiving protruding plate 19 that are locked to each other by the connecting portions 7 and 7 in the vertical direction.

(c) Subsequently, by lowering the bottom surface member 30 (FIG. 8 (b) (c)), overlaps the tip 21a of the tip 14a receives Veneer 21 of the engaging pieces 14 of the locking veneer 12 to lock each other (FIG. 17 (a)). In this state, if each part face material 29, 30 is fixed to the face frame 41 of the transportation carriage, etc., the locking is not released, so there is no problem in the function of the face material protecting the load.

Further, the lower face member 30 is lowered and deeply locked so that the back surface 12a of the locking protrusion 12 and the lower surface 22 of the receiving protrusion 21 are completely overlapped (FIG. 8 (c) ). In this state, even if the upper face material 29 is fixed to the lateral reinforcing material 53, the locking of the both is not released, and further, rattling of the face materials 29, 30 and the like can be prevented. The trolley 67 can travel more stably.

(d) In this state, the mounting plate 33 of the lower face member 30 overlaps the lateral reinforcing member 53 of the front frame 59, and a through hole (not shown) of the lateral reinforcing member 53 and the mounting hole 36 of the mounting plate 33. And are fixed together with screws, pins or the like (see FIG. 7 (d), see FIG. 6).

(e) As described above, the attachment of the face materials 29 and 30 to the front frame 59 is completed, and the face materials 29 and 30 are in a state in which the lateral reinforcing material 53 is sandwiched between the connecting plates 7 and 7 of the double-sided materials 29 and 30. Therefore, the double-sided materials 29 and 30 are stably attached by being supported by the reinforcing material 53. That is, even when an internal pressure due to the load or an external pressure from the outside is involved, the double-sided materials 29 and 30 are prevented from being deformed so as to protrude outwardly or inwardly. It can prevent moving outside.

Further, since the thickness t ₁ of the connecting plate 7 is formed to be thinner than the thickness t _{0 of the} substrate, and the back surfaces of the connecting plate 7 and the substrate 26 are formed flush with each other, 29 and 30 are formed flush with each other.

(2) Next, attachment with the left and right side frames 44 and 46 will be described.

(a) The left and right side frames 44 and 46 are prepared by preparing two intermediate surface materials (upper and lower) 24 and 24 for the upper surface material 29 and the lower surface material 30, respectively. First, the mounting plate 33 of the upper face material 29 is overlapped with the lateral reinforcing material 55 of the side frames 44 and 46, the through holes (not shown) of the lateral reinforcing material 55, the mounting holes 36 and 36 of the mounting plate 33, And are fixed together with screws, pins, etc. (FIGS. 6 and 7 (d)).

(b) in this state, between the opening 10 and 19 of the connecting plate 7 of the upper surface member 29 (the part between. width H ₄ engaging veneer 12 and the opening 19), next to the intermediate reinforcements 53 8 is positioned (FIGS. 8A and 8B), the connecting plate 7 of the upper face member 29 and the upper connecting plate 7 of the intermediate face member (upper side) 24 are overlapped while sandwiching the lateral reinforcing member 53. The locking protrusion 12 and the receiving protrusion 21 are locked to each other ( see FIG. 8C). Similarly, the intermediate portion is laterally reinforced between the openings 10 and 19 (between the locking projection plate 12 and the opening 19, the width H ₄ portion) of the connecting plate 7 below the intermediate portion face material (upper side) 24. The material 53 is positioned, and the connection plate 7 on the upper part of the intermediate surface material (lower side) 24 is overlapped on the connection plate 7 of the intermediate surface material (upper side) 24 while sandwiching the horizontal connection rod 53, a veneer 21 receives an engagement protruded plate 12 engaging each other (see FIG. 8 (c)).

(c) Subsequently, the connecting plate 7 of the lower face member 30 is overlapped with the connecting plate 7 on the lower part of the intermediate face member (lower side) 24 with the lateral reinforcing member 53 sandwiched therebetween, and similarly received with the locking protrusion plate 12. The protruding plates 21 are locked together. The mounting plate 33 of the lower face member 30 overlaps the lowermost horizontal reinforcing member 53, and a through hole (not shown) of the horizontal reinforcing member 53 and the mounting hole 36 of the mounting plate 33 are communicated with each other by screws and pins. Fix it together with etc.

Thus, the attachment of the face materials 24, 29, 30 to the left and right side frames 44, 46 is completed (FIGS. 2A and 2B). Even if the mounting height of the lateral reinforcing rod 53 and the relative position of each face material are slightly deviated, the “shift” can be absorbed by the gap H ₄ between the openings 10, 19, and the locking protrusion 12 and the receiving protrusion 21. Can also be attached to the face members 24, 29, 30 by absorbing the “displacement”.

(3) Also, in the rear frame 41, each of the upper surface material 29 and the lower surface material 30 is attached to each surface material in the same manner using two intermediate surface materials (upper and lower) 24, 24 (see FIG. 3).

(4) As described above, the face materials 24, 29, and 30 are attached to the respective frames 41, 44, 46, and 59 to constitute the transportation carriage 67 of the present invention (FIGS. 1 to 3). Further, since the connecting plates 7 having the same structure are formed by the face members 24, 29, and 30, the connecting plates 7 can be connected to each other without considering the vertical direction of the face members 24, 29, and 30 when connecting. It is possible to attach the face material with a simple operation while stacking.

  In addition, the signboard 68 can also be attached to the upper surface material 29 of the left side frame 44 by using the recess 38 (FIG. 2A).

[3] Other embodiments

  In the said Example, if the carrier cart used as a base has the frame for preventing load collapse which attaches a face material, it will not be restricted to the said Example. For example, the present invention can be applied to a configuration in which only the left and right side frames 44 and 46 are provided and the rear frame 41 and the front frame 59 are omitted, a six-wheel carriage, and the like (not shown).

  Moreover, in the said Example, although the horizontal reinforcing material 53 of the trolley | bogie 67 was pinched | interposed in all the connection board parts which each surface material accumulated, the horizontal reinforcement material 53 is at least 1 place of the overlapping connection board part. If it is clamped, the movement of the connected face materials can be restricted (not shown).

  Another embodiment of the present invention will be described with reference to FIGS. This embodiment is an embodiment in which the structure of the connecting plate 7 and the mounting plate 33 is changed with the face material of the first embodiment. In each face frame of the transportation carriage to which the face material is applied, the lateral reinforcing members 53 and 55 are used.

When the lower face material 30 is lowered and the locking projections 12 and the receiving projections 21 are locked by the connecting plates 7 and 7, the lateral reinforcing material 53 contacts the edges of the reinforcing material accommodating portions 72 and 72. In contact therewith, the movement is restricted (FIG. 16B), and the face materials 29 and 30 do not fluctuate while the transport cart 67 is running. Further, the intermediate shelf 66 can be operated by inserting a hand or the like using the openings formed by the notches 71 and 71 of the face members 14, 19 and 30.

  Even when the locking projections 12 and the receiving projections 21 are loosely locked by the connecting plates 7 and 7 (FIG. 17B), the double-sided materials 29 and 30 are used as the frame of the transport carriage 67. If attached, there is no possibility that each face material will come off. Therefore, this face material can be applied even when the positions of the structural bars such as the lateral reinforcing material 53 and the face frames 41, 44, and 46 are slightly different. In particular, this is effective when the diameter of the lateral reinforcing material 53 is large (FIG. 17B, a chain line 53A).
