【Example】
Hereinafter, examples of the present invention will be described. However, these examples are provided for illustrative purposes and do not limit the present invention.
[0010]
[Example 1]
1 and 2 show a front view and a plan view of a straight type (non-folding type) bridge. The bridge main body has a single step plate (2) fixed between left and right side plates (1) and (1). (3) is a handle which is attached to the outside of one or both side plates (1) so as to be able to undulate, and is located at the longitudinal center of gravity of the bridge.
The upper surface of the step plate (2) (the step surface on which the vehicle or the like travels) is a non-slip surface (4) using an abrasive as shown in FIG. ing. The non-slip surface (4) can be formed by laminating a non-slip sheet or film (commercial product name: non-slip NCA) using an artificial abrasive.
As shown in FIG. 4, which shows a cross-sectional view taken along the line DD in FIG. 3, the upper side of the side plate (1) is opposed to the outer side, and the lower side of the side plate (1 '') is opposed to the inner side. A step plate (2) is fixed between the upper and lower central portions of the side plate body, and the side plates (1) (1) and the step plate (2) Consists of a long extruded product of aluminum or aluminum alloy.
[0011]
At both ends in the longitudinal direction of the bridge main body, as shown in FIG. 5, the upper flange plate (1 ') on the step surface side and the subsequent side plate (1) are beveled (6) obliquely. A cap case (5) adapted to the above is welded and fixed to the upper end face of the bridge body.
As shown in FIG. 4, a plurality of ribs (ridges) (7) extending in the longitudinal direction are extruded in advance on a surface (back surface) opposite to the step surface of the step plate (2). As shown in FIG. 5, an end connection plate (8) for suspending one end in the longitudinal direction of the bridge on the bed of a truck or other loading vehicle is fitted and connected.
The connecting plate (8) having the same width as the bridge is chamfered (8 ') (8') on both sides on the fitting side so as to have a width which can be fitted between the side plates (1) and (1), and this chamfering is performed. A longitudinal groove (8 ″) into which the above-mentioned rib (7) fits is cut between (8 ′) and (8 ′), and is contact-fitted to the back surface of the step plate to be connected and fixed.
The back surface of the connection plate (8) is a non-slip surface (4) similar to the step plate (2). Due to the non-slip surface (4), the back surface of the connecting plate (8) is frictionally engaged well with the loading platform of the loading vehicle, and the engagement during use of the bridge is ensured.
[0012]
FIG. 6 shows a completed assembly view of FIG. 5, in which the cap case (5) is fitted and fixed to the chamfered portion (6).
FIG. 7 shows an end connection plate (9) for grounding the other end in the longitudinal direction of the bridge. The end connection plate (9) is formed of a hollow tapered plate having a flat triangular cross section. A lateral non-slip rib (9 ') is provided and has a reinforcing partition (9'') inside. The rear end face where the taper is open has an opening with a U-shaped cross section. The step plate (2) and the lower flange plate (1 '') at the bridge end are sandwiched and fitted between the upper and lower surfaces of this opening, and welding is performed. Fix it. At this time, the upper surface of the connection plate (9) is on the extension surface of the step plate (2), and the lower surface is inclined upward toward the tapered end, so that the connection plate (9) is stably grounded when using the bridge. Contact.
[0013]
[Example 2]
FIG. 8 is an enlarged view of an AA part of FIG. 2 of another example.
As shown in FIG. 9 in the BB section and FIG. 10 in the CC section, the step plate (2) has a substantially triangular cut-and-raised projection ( 10) is provided.
The configuration of the side plate (2) is the same as that of the first embodiment.
The configuration of the end connection plate for grounding is the same as that of the first embodiment (FIG. 7), but the configuration of the end connection plate for the cargo bed is shown in FIGS. 11 and 12.
In FIGS. 11 and 12, the end connection plate (9) is fixed with its upper and lower surfaces inverted from those in FIG.
Therefore, the lower surface of the connection plate (9) extends on the extension of the lower edge of the side plate (1) (the lower surface of the lower flange plate (1 '')), and the upper surface of the connection plate (9) is tapered downward from the end of the step plate (2). So that the transfer from the step board (2) of the vehicle to the bed surface is performed smoothly. In this case, in order to ensure the engagement of the connecting plate (9) with the carrier, both sides of the lower surface (the surface opposite to the step surface) of the front end closed in a tapered shape have an L-shaped hooking plate ( 11) is fixed.
Instead of the L-shaped hooking plate (11), the end connection plate (8) used in FIGS. 5 and 6 can be welded and extended as shown in FIG.
[0014]
[Example 3]
This example shows the folding type of the first and second embodiments.
As shown in FIG. 14, the bridge body is divided into two parts in the longitudinal direction, and an end connection plate (8) or (9) is connected and fixed to one end of each divided bridge body, and a side plate (1) is connected to each other end. The hinges (12) having a flat U-shape are fixed to each other, and the downwardly-curved tips of the hinges (12) (12) of the left and right split bridge bodies are pivotally supported by pins (13). On the hinge-side end surface of the upper flange plate (1 '), a butting projection (14) is formed which abuts each other when the left and right bridge bodies are extended in a straight line.
The handle (3) is attached to each of the left and right bridge bodies, and the attachment position is set at the longitudinal center of gravity in a state of being folded in two as shown in FIG.
The handle (3) is supported by a pin (15) at the lower part on the outer side of the side plate (1) so as to be able to move up and down in the direction of the arrow.
