 Next, an embodiment in which the present invention is applied to a carrier with a connecting arm used for carrying glass plates will be described.

In the present invention, the object to be transported is not limited to the glass plate, but may be any other plate-shaped object.

The carrier with an articulating arm according to the present embodiment has a basic structure that follows that of the conventional carrier structure. That is, as shown in FIG. 5, the carrier of this embodiment is provided with a rectangular base portion (1), and a back support portion (2) as a tilting prevention portion is provided upright at the rear edge portion thereof. At the same time, the front protection part (3), which also functions as a tilt prevention part, is erected on the front edge so as to be tiltable forward, and the back support part (2) and the front protection part (3) are provided on both sides thereof. They are connected by the connecting arm (4) at an intermediate position in the edge height direction.

Further, in the same manner as in the conventional art, the rear end portion of the connecting arm (4) is pivotally attached to the side edge portion of the back support portion (2) while the front end portion thereof is swingable. The side edge portion of the front surface protection portion (3) is detachably hooked in such a manner that upward disengagement is permitted.

This locking mechanism is also similar to the conventional one in its basic structure.

That is, as shown in FIG. 1, at the side edge of the front surface protection part (3), a locking male part consisting of a proximal end constricted part (5a) and a large engagement part (5b). (5) is attached to the side protruding state.

Further, the connecting arm (4) is formed in a U-shape in a lateral cross section, and a lower wall (4a) at a front end portion thereof has an engaging diameter of the engaging male portion (5). An introduction opening (6) for introducing the large portion (4b) is formed, and the inner wall (4b) communicates with the introduction opening (6) to form a base end of the latching male portion (4). An engaging slit-like notch (7), which is relatively narrower than the engaging male part (5) and allows insertion of the constricted part (4a), is formed to extend upward.

As described above, the basic structure of the carrying tool with the connecting arm is the same as that of the conventional carrying tool. However, in addition to the above basic structure, the carrying tool further includes an upward connecting arm. It is completely different from the conventional carrier in that it is provided with an elastic body (8) for suppressing the separation of (4).

That is, this elastic body (8) is made of a stainless steel strip plate material for spring, and as shown in FIGS. 2 and 3, the engaging large diameter portion (5b) of the male portion (5) is used. ) Surrounding more than half the circumference and holding the large diameter portion (5b) by elastic restoring force (8a), and downward from both ends of this elastic holding portion (8a). A pair of large-diameter part introducing feet (8b) (8b) extended so as to open in a “C” shape, and an outward facing joint connected to the lower ends of the feet (8b) (8b). It is configured to integrally have the character-shaped engaging piece portions (8c) and (8c). There is no particular limitation on the material of the elastic body (8).

In the elastic body (8), the U-shaped engaging piece portions (8c) (8c) face each other in the arm length direction of the introduction opening (6) of the arm lower wall (4a). The peripheral edge portions are fitted and engaged with each other, and mounted on the arm lower wall (4a) along the engaging notches (7).

This mounting work is performed as follows, for example.

That is, as shown in FIG. 4, one of the U-shaped engaging piece portions (8c) of the elastic body (8) is fitted to one side edge portion of the large diameter portion introducing opening (6). Then, the elastic body (8) is pressed inwardly, and the other engaging piece portion (8c) is fitted and engaged with the other side edge portion of the introduction opening (6). As a result, the elastic body (8) is attached to the arm (4) in an appropriate attachment state in which it does not fall due to its own elastic action.

The mounting procedure is not particularly limited. Therefore, in addition to the procedure described above, for example, the elastic body (8) is pressed from both sides, and in that state, both engaging piece parts are (8c) (8c) may be fitted and engaged with the both side edges of the introduction opening (6) according to a desired procedure.

Reference numeral (9) is a concealing plate which also serves as a positioning guide for the elastic body (8). Further, in the carrier shown in FIG. 5, (11) and (11) are swingable connecting arms that can be hooked and connect the back receiving portion (2) and the front surface protecting portion (3) at the upper edge portion. . Further, (12) is a glass plate front surface holding device for holding the front surface portion of the glass plate (G) in a positioned state in accordance with the amount of the glass plates stored.

In the vehicle with the connecting arm having the above-described structure, for example, as shown in FIG. 1, the hooking operation of the connecting arm (4) performed after the glass plate (G) is housed is performed in the same manner as the conventional art. This is done by moving the front end of (4) from the position above the introduction male part (5) to the bottom.

During this transition process, the engagement large diameter portion (5b) of the latching male portion (5) passes through the introduction opening (6) and the introduction foot portions (8b) and (8b) of the elastic body (8). Introduced between, the elastic body (8) is inflated outward against the elastic restoring force in the process of introduction, and then enters the arcuate holding portion (8a). As a result, the engagement large-diameter portion (5b) is held in the arcuate holding portion (8a) in a state where it is prevented from coming off, and the front end portion of the connecting arm (4) is inadvertently separated upward. Is held in a suppressed state.

Then, during the transportation of the glass plate (G) by the carrier with the connecting arm, the connecting arm (4) may float upward around the rear end pivot portion due to vibration, impact or the like. As a result, the elastic body (8) holds the engagement large-diameter portion (5b) to prevent the floating of the engagement arm (4), which prevents unintentional unhooking behavior of the connecting arm (4), and the transportation of the load is reduced. It can be performed safely and securely without causing collapse.

Then, when the glass plate (G) is taken out of the carrier after transportation, when the hooked state of the front end of the connecting arm (4) is released, the arm (4) is swung upward. If it is moved, the engagement large-diameter portion (5b) is withdrawn from the elastic body (8) against the elastic restoring force thereof, and then comes out of the introduction opening (6), so that the hooked state is maintained. It will be canceled.

As described above, in the above-described carrier, since the holding force of the elastic body (8) reinforces the hooking force of the connecting arm (4), the connecting arm (4) during transportation is The glass plate (G) can be transported to the destination safely and securely by preventing the unintentional release of the hooked state of the connecting arm (4), and the connecting arm (4) can be locked and unlocked. The operation can be performed by an extremely simple operation of raising and lowering the connecting arm (4) in the same manner as in the past, although there is elastic resistance by the elastic body (4).

In addition, since the above-mentioned carrier can be completed only by externally adding the elastic body (8) to the conventional carrier, no significant design change of the conventional carrier is required, and the cost is reduced. The carrier can be manufactured and provided very advantageously.
