  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

  As shown in FIG. 1, the vehicle carrier support structure and device of Example 1 according to an embodiment of the present invention has a mounting 2 mounted on a frame 1 of a transportation vehicle, for example, and a vertical joist 6 on the mounting 2. The loading platform 10 is attached via the Yokojinta 9.

  As shown in FIG. 2, the mounting 2 includes a fixing bolt 3, a fixing member 4, a reinforcement member, and a frame 1 via a lower plate 2 </ b> B that engages with the lower side of the pair of rubber elements 2 </ b> A and 2 </ b> A in FIG. 2. It is attached by the member 5 or the like. The mounting 2 corresponds to an example of a vehicle bed support device according to the present invention, and the rubber elements 2A and 2A correspond to an example of an elastic element according to the present invention.

  Here, as shown in FIG. 1, five mountings 2 according to the first embodiment are provided in the vehicle front-rear direction of the left and right frames 1 extending in the vehicle front-rear direction.

  A vertical joist 6 made of wood or the like is placed along the frame 1 on the upper plate 2C that engages the upper side in FIG. 2 of the pair of rubber elements 2A and 2A that are components of the mounting 2, and is a fixing member. 7. The upper plate 2C and the vertical joist 6 are fastened and fixed via a fixing bolt 8 or the like.

  For example, a metal joist 9 extending in a direction intersecting the vertical joist 6 is placed on the joist 6, and a loading platform 10 is placed on the joist 9. It is like that.

  As shown in FIG. 3, the mounting 2 includes, for example, a pair of rubber elements 2A and 2A arranged in the longitudinal direction of the vehicle, and a lower plate 2B joined to the lower surface of the pair of rubber elements 2A and 2A. The upper plate 2C is joined to the upper surfaces of the pair of rubber elements 2A, 2A.

  Both ends of the lower plate 2B in the vehicle front-rear direction are bent upward in FIG. 3, and the upper plate 2C is folded so that both ends of the lower plate 2B in the vehicle front-rear direction cover the bent portion of the lower plate 2B. It is bent downward in FIG. That is, when viewed from the front-rear direction of the vehicle, the bent portion of the lower plate 2B, the upper play, and the bent portion of 2C overlap each other in a predetermined manner.

  And the rubber | gum 2D is joined to the bending part side of the lower side plate 2B of this superimposition part, for example, the upper plate 2C (loading side) is set with respect to the lower side plate 2B (frame 1 side) at the time of braking of a vehicle. When a relatively large deceleration acceleration is received and the front plate 2C is displaced relatively forward, the bent portion of the upper plate 2C contacts the bent portion of the rubber 2D and then the lower plate 2B. Side) relative to the lower plate 2B (frame 1 side) relative to a predetermined amount or more, and the rubber 2A is prevented from being damaged.

  Further, as shown in FIG. 4, one end portion of the lower plate 2B of the mounting 2 in the left-right direction of the vehicle is bent upward in FIG. 4, and the bent portion of the lower plate 2B is the one end portion of the upper plate 2C. The upper plate 2C is bent downward in FIG. 2 so as to cover one end portion corresponding to. That is, when viewed from the left-right direction of the vehicle, the bent portion of the lower plate 2B and the bent portion of the upper plate 2C are overlapped with each other in a predetermined manner.

  And the rubber | gum 2E is joined to the bending part side of the lower side plate 2B of this superimposition part, for example, when the vehicle turns, the upper side plate 2C (loading side) is made with respect to the lower side plate 2B (frame 1 side). When a relatively large turning acceleration is received and the left plate in FIG. 4 is relatively displaced, the bent portion of the upper plate 2C abuts on the rubber 2E and then the bent portion of the lower plate 2B. The plate 2C (loading platform side) is configured to restrict the relative displacement of the lower plate 2B (frame 1 side) relative to a predetermined amount or more, and to prevent the rubber 2A from being damaged.

  Here, the rubber elements 2A and 2A are divided into two because the reinforcing member 5 can be penetrated in the vehicle left-right direction, and as described above, the upper plate 2C (loading platform side) is the lower plate 2B. Although it is relatively displaced in the front-rear direction in FIG. 3 or in the left-right direction in FIG. 4 with respect to the (frame 1 side), the area of the rubber element surface substantially perpendicular to the relative displacement direction can be increased by dividing it into two. This is because even when the rubber element has a desired elastic coefficient, deterioration of the rubber element in a direction in which a relatively large acceleration or deceleration G acts can be effectively suppressed.

  According to the vehicle carrier support device according to the first embodiment, from the frame 1 side by appropriately setting the elastic coefficient of the rubber element 2A of the mounting 2 interposed between the vehicle body frame 1 and the carrier 10. Occurrence of damage such as damage when transporting delicate items including strawberries by suppressing transmission of appropriate vibration (for example, vibration in the region of 10 Hz to 30 Hz including 20 Hz) to the loading platform 10 side Can be effectively suppressed.

  In addition, like the vehicle carrier support device according to the first embodiment, the reinforcing member 5 that is disposed by penetrating the rubber elements 2A and 2A in the lateral direction of the vehicle is used, and the frame 1 is interposed between the lateral direction of the vehicle. Since the lower plate 2B (frame 1 side) of the mounting 2 can be attached to the frame 1 by fastening the bolts 3 (or U-shaped bolts) from both sides, special processing or the like is required for the frame 1. Since it is not necessary, it is possible to use the same frame 1 as the vehicle that does not require the vehicle carrier support device, thereby reducing the product cost.

  In addition, complicated processing or the like is not necessary and can be attached later in the market. Therefore, it can be easily attached at a bodybuilder or a service factory according to the user's request. For this reason, for example, it is easy to mount and change the loading platform (so-called flat body, wing type, aluminum van, cold storage vehicle, etc.) according to the user's request after shipment of the vehicle, and the user-friendly vehicle loading platform support An apparatus can be provided.

  Here, in the first embodiment, for example, it is assumed that the rubber elements 2A and 2A are deteriorated due to aging and other factors. For example, when a strong impact is applied due to a collision accident or a rollover accident, the rubber element 2A 2A is provided with a stopper structure (stopper device) 100 for reliably avoiding a possibility that the load carrier is detached from the frame of the vehicle due to damage.

  In the stopper structure (device) 100 according to the first embodiment, as shown in FIGS. 5A to 5C, the frame-side stopper 101 extending in the vehicle vertical direction has a side surface of the vehicle-side frame 1.

Further, a loading platform side stopper 110 is mounted on a side surface of the vertical joist 6 (corresponding to an example of the loading platform mounting portion of the present invention) on the loading platform 10 side.
As shown in FIGS. 5 (A) and 5 (B), the loading platform side stopper 110 extends in the vehicle front-rear direction, and as shown in FIG. 6 is provided so that a gap 112 is formed between the two and the vehicle 6 and is attached by a method such as bolt fastening in the vicinity of both ends in the vehicle front-rear direction.

  As shown in FIGS. 5A to 5C, the frame-side stopper 101 extends upward along the side surface of the vertical joist 6 from the attachment portion to the frame 1, and is a gap between the loading platform-side stopper 110. A front / rear / left / right direction restricting portion 101A penetrating through 112, and an up / down direction restricting portion 101B connected to the front end of the front / rear left / right direction restricting portion 101A and bent in a direction overlapping with the vertical joist 6 when viewed from above the vehicle; , And is configured.

  In such a stopper structure 100, the frame-side stopper 101 and the carrier-side stopper 110 do not interfere with each other during normal traveling, but a large input (impact) is applied to the carrier 10 due to, for example, a collision or rollover. When it acts, it can prevent reliably that the loading platform 10 leaves | separates from the flame | frame 1 side.

  Specifically, with respect to the input (impact) in the vehicle longitudinal direction, as shown in FIGS. 5A and 5B, between the raised portion 111 of the loading platform side stopper 110 and the vertical joist 6. Due to the engagement between the vehicle longitudinal direction end of the vehicle longitudinal direction restricting portion 101A of the frame side stopper 101 inserted through the gap 112 and the vehicle longitudinal direction end inside the raised portion 111 of the cargo platform side stopper 110, The relative movement with respect to the frame side is restricted, and the loading platform is reliably prevented from being detached from the frame.

  As shown in FIGS. 5A to 5C, an input (impact) in the vehicle left-right direction is inserted through a gap 112 between the raised portion 111 of the loading platform side stopper 110 and the vertical joist 6. By engaging the vehicle left-right direction surface of the vehicle front-rear left-right direction restricting portion 101A of the frame-side stopper 101 and the vehicle left-right direction surface or the vertical joist 6 side surface inside the raised portion 111 of the load platform-side stopper 110, The relative movement between the frame and the frame side is restricted, and the loading platform is reliably prevented from being detached from the frame.

  For the input (impact) in the vehicle vertical direction, as shown in FIGS. 5 (A) and 5 (C), the vehicle vertical direction lower surface of the vertical direction restricting portion 101B of the frame side stopper 101 and the vertical joist The relative movement between the loading platform side and the frame side is regulated by the engagement with the upper surface of 6, and the loading platform is reliably prevented from being detached from the frame.

  Note that the stopper structure (device) 100 according to the first embodiment is provided independently of the mounting 2 that is a vehicle carrier support device. Accordingly, the installation location of the stopper structure (device) 100 has a high degree of freedom, and can be easily attached to an appropriate location without performing complicated processing or the like.

  As described above, the stopper structure (device) 100 according to the first embodiment does not require complicated processing and the like, and can be attached later in the market. It can be easily installed in service factories. For this reason, for example, it is easy to attach or change the loading platform (so-called flat body, wing type, aluminum van, cold storage vehicle, etc.) after the vehicle is shipped, and provide a user-friendly stopper device. can do.

  In addition, as shown in FIG. 1, two such stopper structures (devices) 100 can be provided in the vehicle front-rear direction of the left and right frames 1, but one or three or more. It is also possible to have a structure provided with each.

  In this embodiment, the frame side stopper 101 (plate-like member) side is attached to the side surface of the frame 1 and the loading platform side stopper 110 side is attached to the side surface of the vertical joist 6 on the loading platform side. It is not limited to this, The frame side stopper 101 (plate-shaped member) side is attached to the side surface of the vertical joist 6, and the loading platform side stopper 110 (the raised portion 111 in which the gap 112 for accommodating the plate-shaped member is formed is formed. A configuration in which the stopper) side is attached to the side surface of the frame 1 on the vehicle side can also be adopted.

  In the second embodiment, a stopper structure (device) 200 is provided instead of the stopper structure (device) 100 of the first embodiment.

  In the stopper structure (device) 200 according to the second embodiment, as shown in FIG. 6, the frame-side stopper 201 having the engagement holes 201A and 201B is attached to the side surface of the vehicle-side frame 1 by a method such as bolt fastening. ing.
