DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for fixing a fixed vehicle-mounted object such as a tool cabinet to a carrier part of a vehicle.

[0002]

2. Description of the Related Art For example, for service such as repair and maintenance of electric appliances, a service car is used in which a tool cabinet storing various tools and parts is fixed to a carrier. As described above, there are many needs for fixing an in-vehicle object such as a tool cabinet to a carrier part of a vehicle. However, the work of fixing the in-vehicle object to the bed portion of the vehicle is unexpectedly troublesome. That is, in order to fix the in-vehicle object to the bed portion, a conventional general method is to open a bolt hole in the floor panel of the bed portion and fix the in-vehicle object by bolting using the bolt hole. Under the floor panel, various structural and functional elements are intricate and should be carefully inspected under the floor panel to prevent accidental damage when drilling bolt holes and impairing the function of the vehicle The work is very complicated. For example, when bolting, it is necessary to work under the bed to pass bolts from below the floor panel.

There is also a method of fixing an on-vehicle object to a carrier without such complicated work. that is,
This is a method in which a base plate formed by cutting a thick plywood into a shape that matches the plane shape of the carrier part is fitted into the carrier part exactly, and a vehicle-mounted object is fixed to the base plate. However, this method has a major drawback in that the cutting of the plywood can only be performed by a specialized contractor, so that it takes a long time to manufacture the base plate, and in fact, it is hardly used in practice.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and does not require complicated work.
In addition, there is no danger of damage to structural or functional elements that affect the function of the vehicle, and no special work is required by the specialist, making it possible for anyone to easily fix the in-vehicle object to the carrier. It is intended to provide a fixing method.

[0005]

SUMMARY OF THE INVENTION A fixing method according to the present invention includes a fixing receiving plate having a plurality of fixing bolts provided to project from an upper surface and having a plurality of rivet holes provided in a predetermined arrangement. It is fixed to the floor panel of the vehicle bed part, and the vehicle-mounted object is fixed to the vehicle bed part using the fixing bolt of this fixed receiving plate, and the fixed receiving plate is fixed to the floor panel, The rivet hole is selected at a position corresponding to the convex surface of the reinforcing unevenness of the floor panel, and the rivet is passed through a locking hole drilled in the floor panel through the rivet hole. As the rivet, an expandable rivet that generates a locking force when the tip is expanded by driving of a driving pin is used.

According to this fixing method, only the fixed receiving plate is directly fixed to the floor panel of the vehicle loading section, and the fixing of the fixed receiving plate is performed by the expansion type rivets. It is not necessary to perform the operation from the side, and the operation can be greatly simplified.

Further, in this method, the fixed receiving plate has a plurality of rivet holes in a predetermined arrangement, and the fixed receiving plate is riveted with the rivet holes that can be selected corresponding to the convex portions of the reinforcing unevenness of the floor panel. Therefore, even when drilling a rivet locking hole in the floor panel, at least always the thickness of the unevenness in the floor panel with the structural elements and functional elements under the floor panel A gap can be secured between them, and by using a drill having a blade length of about the thickness of the unevenness, it is possible to reliably prevent damage to structural elements and functional elements below the floor panel. In other words, there is no need to worry about the risk of damage to the structural and functional elements under the floor panel, which can also greatly improve workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.
The present embodiment relates to an example in which a tool cabinet 2 is fixed to a carrier 1 of a one-box type vehicle as shown in FIG. 5, and specifically, as shown in FIG. In FIG. 5, the structure is such that the tool cabinet 2 is fixed to the floor panel 4 of the bed part 1 of the vehicle with the expandable rivets 5 and the fixing bolts 6 of the fixing receiving plate 3 are used.

As shown in FIG. 2, the fixed receiving plate 3 has a rectangular shape corresponding to the shape of the bottom surface of the tool cabinet 2 as a whole, and has a rising portion 3f on a side in the longitudinal direction. Notch 7 that enters inside from the side of the side
Is provided. The notch 7 is provided for avoiding the tire house in the case of a vehicle in which the tire house protrudes from the carrier, and is provided as necessary. The fixed receiving plate 3 is provided with a plurality of rivet holes 8, 8,... Located at both ends in the longitudinal direction. These rivet holes 8 are provided in an array arranged on a line perpendicular to the longitudinal direction, and two rows are provided for each end. With such an arrangement, the floor panel in the bed portion of a general vehicle can correspond to the pattern of the reinforcing unevenness provided thereon. That is, any rivet hole can always be made to correspond to the position of the uneven pattern. The fixing receiving plate 3 is further provided with fixing bolts 6 protruding from the upper surface thereof. The fixing bolt 6 is provided with a rivet hole 8.
Are provided one at each of the four corners so as to be close to the arrangement line.

[0010] As shown in FIG.
A rivet body 10 and a driving pin 11 fitted to the rivet body 10. The driving pin 11 is driven by a hammer or the like as indicated by an arrow, so that an extended portion 12 of the rivet body 10 is formed in a cross-shaped groove. 13, the fixed receiving plate 3 and the floor panel 4 are sandwiched between the extended portion 12 and the locking head 14 so that the fixed receiving plate 3 is fixed to the floor panel 4. To fix.

In order to use the expandable rivet 5, first, a locking hole 15 is formed in the floor panel 4 corresponding to the rivet hole 8 of the fixed receiving plate 3, and then the rivet hole 8 and the locking hole 15 are formed. After passing through the expandable rivet 5, the driving pin 11 is driven by a hammer or the like until the whole of the driving pin 11 sinks into the locking head 14 as described above. At this time, the locking holes 15 are drilled in the floor panel 4 through the rivet holes 8 at positions corresponding to the convex portions 4a of the reinforcing irregularities of the floor panel 4. For this, a drill blade 16 as shown in FIG. 4 is used.

The drill blade 16 has a blade portion 17 having a length approximately equal to the thickness of the unevenness on the floor panel 4, specifically, a length of 10 mm. A stopper surface 19 is formed by a handle portion 18 having a larger diameter. Therefore, when drilling holes on the convex portion 4a of the floor panel 4 using the drill blade 16, the length of the blade portion 17 projecting below the convex portion 4a is set to be equal to or less than the length of the unevenness of the floor panel 4. That is, the blade portion 17 can be prevented from protruding below the concave surface portion 4b of the floor panel 4. Therefore, even if there is a structural element or a functional element of the vehicle below the drilling position, it is possible to reliably prevent the structural element or the functional element from being damaged.

In order to fix the tool cabinet 2 by using the fixing receiving plate 3 fixed to the floor panel 4 as described above, the fixing receiving plate 3 passed through a bolt hole provided on the bottom surface of the tool cabinet 2 is formed. The fixing bolt 6 is tightened with the nut 20.

All of the above-mentioned operations of the fixing method according to the present invention can be performed only on the upper side of the floor panel 4, and when the floor panel 4 is pierced, the state of the lower side of the floor panel 4 is kept. No need to confirm. Therefore, anyone can easily do this.

[0015]

As described above, according to the present invention, it is possible to greatly simplify the work of fixing the in-vehicle object to the bed portion. For example, in the industry where a service car having a tool cabinet fixed to the bed portion is used. It can greatly contribute to rationalization.
