Japanese Utility Model Laid-Open No. 60-152766 JP 2006-52586 A

However, the technique disclosed in Patent Literature 1 does not specifically describe a method of fixing the handle. Also, with the technique disclosed in Patent Document 2, although the handle is surely fixed, a plurality of steps must be taken to fix the handle, and the work is complicated. Furthermore, for example, when used in a container for transporting industrial waste and handled roughly, there is a possibility of malfunction due to an external impact.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a handle fixture that facilitates fixing of the handle and that is excellent in durability.

The handle fixture of the present invention comprises:
A handle fixture used in a door fixing device that fixes a door by operating a rod-shaped handle,
a hinge provided on the door or a mounting frame of the door;
a first retaining portion that extends in a direction orthogonal to the axis of the hinge, rotates together with the axis of the hinge, straddles the handle at the operating end of the handle, enters the operating range of the handle, and restricts the movement of the handle;
an extending portion extending from the tip of the first fastening portion in a direction along the axis of the hinge;
a second fastening portion provided at the tip of the extending portion and provided with a recess portion into which the handle fits when the first fastening portion straddles the handle and is further rotated,
When no external force is applied, the handle and the first fastening portion interfere with each other to maintain the regulated or non-regulated state of the handle, and when an external force is applied, the handle, the hinge, or at least a part of the first fastening portion is temporarily deformed or displaced, whereby the regulated state and the non-regulated state of the handle are switched.
When an external force is not applied, the handle and the second fastening portion interfere with each other to maintain the regulated or non-regulated state of the handle, and when an external force is applied, the handle, the hinge, the first fastening portion, the extending portion, or at least a part of the second fastening portion is temporarily deformed or displaced, whereby the regulated state and the non-regulated state of the handle are switched.

According to the handle fixing device of the present invention, the handle can be fixed simply by rotating the first fastening portion, the extending portion, and the second fastening portion around the axis of the hinge. Further, the handle is fitted into the recessed portion of the second fastening portion while the first fastening portion straddles the handle. Therefore, even if the handle is detached from the second retaining portion, the movement of the handle is restricted by the first retaining portion, so that the door is not detached. Moreover, it is possible to integrally configure from the first fastening portion to the second fastening portion, so that a simple configuration can be achieved. Therefore, it is resistant to external impact and has excellent durability. It should be noted that the external force is intended to include not only manual force, but also the application of force using some kind of actuator such as a fluid cylinder or an electric motor.

Preferred examples of the handle fixture of the present invention are:
The first fastening portion is inclined so that the interference with the handle becomes stronger toward its tip.

Preferred examples of the handle fixture of the present invention are:
A detachment prevention portion is provided on a side of the second fastening portion opposite to the door and is brought into contact with a side surface of the handle in a state where the handle is fitted in the second recess portion.

According to these preferred examples of the handle fixture of the present invention, it is possible to more effectively prevent the handle from coming off the handle fixture.

As described above, according to the handle fixing device of the present invention, the handle fixing work can be easily performed, and the handle fixing device can have excellent durability.

Figure 3 is a plan view of the handle fixture shown in Figure 2; Figure 3 is a side view of the handle fixture shown in Figure 2; FIG. 10 is a diagram for explaining the operation of the handle fixture when releasing the handle; FIG. 10 is a diagram illustrating another embodiment of a handle fixture;

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a handle fixture 1 of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, the handle fixture 1 of this embodiment is used in a door fixing device 50 that fixes a door 62 by operating a bar-shaped handle 55, and fixes the handle 55 at its operating end.

First, the door fixing device 50 will be described with reference to FIG. Here, the door of the loading platform 61 of the truck 60 or the rear door 62 of the container loaded on the loading platform 61 will be described as an example. The rear door 62 is double-opened, and is attached to left and right attachment frames 63 of the loading platform 61 by hinges 64, respectively. A locking pin 51 is provided on the upper portion of the left rear door 62 . A fixing plate 52 having a notch 53 for fitting the locking pin 51 is rotatably provided above the right rear door 62 by a pivot pin 54 . Further, a rod-shaped handle 55 is attached to the fixed plate 52, and by operating the handle 55 in the direction of the dashed double-headed arrow in the figure, the fixed plate 52 is rotated, and the left and right rear doors 62 are fixed or opened. In the state shown in FIG. 1, the handle 55 is at the operating end with the rear door 62 fixed. Further, as indicated by the dashed line, by moving the tip 56 of the handle 55 in the lower left direction, the fixed plate 52 springs up around the pivot pin 54 to open the rear door 62 . Although the door fixing device 50 using the fixing plate 52 has been described here, it can be applied to various door fixing devices as long as the mode is one in which the handle is operated. For example, it may be a door fixing device that operates a fixture called round drop using a handle. Moreover, it is also possible to use it not only for the rear door 62 of the truck 60 but also for various doors.

Next, the structure of the handle fixture 1 according to the first embodiment will be described with reference to FIGS. 1 to 4. FIG. The handle fixture 1 of this embodiment includes a hinge 10 , a first fastening portion 20 , an extending portion 22 , a second fastening portion 23 and a detachment prevention portion 26 . In FIG. 2, the handle 55 is at the operating end, the arrow a indicates the trajectory of the handle tip 56 when the handle 55 is operated, and the arrow b indicates the trajectory of the handle tip 56 when the handle 55 is bent (the same applies to FIG. 5A).

The hinge 10 has a tube 13 provided on the rear door 62, and an internal shaft 12 is rotatably supported by the tube 13. As shown in FIG. In this embodiment, the hinge 10 is attached to the reinforcing frame 65 of the door via the mounting plate 11 . Further, the shaft 12 is arranged not to move in the vertical direction in FIG. Although not shown, it is also possible to provide the hinge 10 to the mounting frame 63 around the rear door 62 as another embodiment.

The first fastening portion 20 is a rod-shaped member that extends from the shaft 12 of the hinge 10 in a direction perpendicular to the shaft 12 and rotates together with the shaft 12 of the hinge 10 . By rotating the handle 55 at the operating end, the first fastening portion 20 straddles the tip 56 of the handle 55 and enters the operating range of the handle 55 to restrict the movement of the handle 55 (see FIG. 5A). Further, by rotating the first fastening portion 20 to a position where it does not straddle the handle 55, interference between the first fastening portion 20 and the handle 55 is eliminated, and the handle 55 can be freely operated (see FIG. 5(B)). Further, the first fastening portion 20 is inclined so that the interference with the handle 55 becomes stronger toward the tip. In this embodiment, as shown in FIG. 2, the tip 21 side faces obliquely upward.

The extending portion 22 is a rod-shaped member that extends from the tip 21 of the first fastening portion 20 in the direction along the axis 12 of the hinge 10 . The direction along the axis 12 of the hinge 10 need not be strictly parallel to the axis 12 of the hinge 10 . In this embodiment, as shown in FIG. 2, the extension 22 is oblique with respect to the axis 12 of the hinge 10 such that the extension 22 is further away from the axis 12 of the hinge 10 toward its distal end. Further, in the present embodiment, the tip 21 of the first fastening portion 20 is bent to clarify the boundary between the first fastening portion 20 and the extension portion 22, but the boundary between the extension portion 22 and the first fastening portion 20 may be smoothed to eliminate the distinction.

The second fastening portion 23 is provided at the tip of the extending portion 22, and is provided with a recess portion 24 into which the handle 55 is fitted when the first fastening portion 20 straddles the handle 55 and is further rotated. As shown in FIG. 4, the second fastening portion 23 of the present embodiment is configured by bending a rod-shaped member into a substantially S-shape. Further, the second fastening portion 23 is provided with a guide portion 25 bent downward so that the handle 55 is smoothly guided to the recess portion 24 .

The detachment prevention part 26 is erected on the opposite side of the rear door 62 of the second fastening part 23 in a state where the handle 55 is fitted in the recessed part 24 of the second fastening part 23, and is brought into contact with the side surface of the handle 55. - 特許庁The detachment preventing portion 26 prevents the handle 55 from getting over the second retaining portion 23 and detaching. In this embodiment, the second fastening portion 23 and the detachment prevention portion 26 are continuously formed by one rod-shaped member.

Next, a handle fixture 100 according to a second embodiment will be described with reference to FIG. In addition, the same code|symbol is attached|subjected to the same location as the steering wheel fixture 1 which concerns on 1st Embodiment mentioned above, and description is abbreviate|omitted. In the handle fixture 1 of this embodiment, the shaft 112 of the hinge 110 extending from the base of the first fastening portion 20 is long and protrudes from the tube 113 of the hinge 110 . A spring 114 is provided on a portion of the shaft 112 protruding from the tube 113 . The spring 114 biases the first fastening portion 20 and the second fastening portion 23 in a direction (upward direction in the drawing) in which the interference with the handle 55 is increased. In addition, by pressing the first fastening portion 20 and the second fastening portion 23 downward in the figure by an external force, the spring 114 contracts, the first fastening portion 20 and the second fastening portion 23 move downward, and interference with the handle 55 is reduced or eliminated. In other words, the shaft 112 of the hinge 110 moves up and down to temporarily displace the hinge 110, thereby changing the positions of the first fastening portion 20 and the second fastening portion 23, thereby changing the degree of interference between the handle 55 and the first fastening portion 20 and the second fastening portion 23.

Next, the operation of the handle fixture 1 of this embodiment will be described with reference to FIGS. 5(A) and 5(B). Here, the operation of releasing the fixation from the state in which the handle 55 is fixed by the handle fixture 1 at its operating end will be described.

First, referring to FIGS. 2 to 4, the state in which the handle 55 is fixed at its operating end by the handle fixture 1 will be described. In this state, the first fastening portion 20, the extending portion 22, and the second fastening portion 23 are rotated clockwise in FIG. Then, the handle 55 is fitted into the recessed portion 24 of the second fastening portion 23 and is in a regulated state. As a result, the handle 55 does not move. In this regulated state, the handle 55 and the recessed portion 24 are urged in the direction of contact and pressing against each other due to the bending of at least part of the handle 55, the first fastening portion 20, the extension portion 22, or the second fastening portion 23. For this reason, unless an external force is applied to further bend and deform at least a portion of the handle 55, the first fastening portion 20, the extending portion 22, or the second fastening portion 23, they will not come off.

Also, when the handle 55 is fitted into the recessed portion 24, the guide portion 25 is raised from the recessed portion 24. - 特許庁Therefore, the handle 55 and the second fastening portion 23 interfere with each other in the free position where no external force is applied, and are configured so that they do not fit naturally. That is, when fitting the handle 55 into the recess 24 , it is necessary to apply an external force to bend at least a portion of the handle 55 , the first fastening portion 20 , the extending portion 22 , or the second fastening portion 23 . In this way, by applying an external force to at least part of the handle 55, the first fastening portion 20, the extending portion 22, or the second fastening portion 23, the handle 55 and the second fastening portion 23 are switched between the regulated state and the non-regulated state. In the handle fixing device 100 according to the second embodiment, instead of bending by at least a part of the handle 55, the first fastening portion 20, the extension portion 22, or the second fastening portion 23, the shaft 112 of the hinge 110 can be moved up and down to displace the hinge 110.

Next, by applying an external force from the state shown in FIG. 2, the handle 55 and the like are bent, and the first fastening portion 20, the extending portion 22, and the second fastening portion 23 are rotated counterclockwise in FIG. At this time, the engagement between the handle 55 and the second fastening portion 23 is released, and the handle 55 is in a non-restricted state in relation to the second fastening portion 23 . However, the first fastening portion 20 straddles the handle 55, and the first fastening portion 20 is inside the trajectory of the tip 56 of the handle 55 indicated by the arrow a in the figure (the fulcrum side of the handle 55, i.e., the pivot pin 54 side of the fixed plate 52). Therefore, the tip 56 of the handle 55 and the first fastening portion 20 interfere with each other in the free position where no external force is applied, and the first fastening portion 20 keeps the handle 55 restricted.

Therefore, by applying an external force, the handle 55 or at least a part of the first fastening portion 20 is bent so that the first fastening portion 20 goes over the tip 56 of the handle 55 (passes under the handle 55 in this figure). Specifically, the user holds the second fastening portion 23 and the extending portion 22 and further rotates them in the counterclockwise direction in FIG. At the same time, the handle 55 may be held and bent in the direction of the arrow b in FIG. 5(A). Then, the handle 55 or at least part of the first fastening portion 20 bends, and the first fastening portion 20 climbs over the tip 56 of the handle 55 . As a result, the state shown by the dashed line in FIG. 3 and the state shown in FIG. In addition, in the handle fixture 100 according to the second embodiment, the axis 112 of the hinge 110 can be moved up and down instead of bending by the handle 55 or at least part of the first fastening portion 20 .

Further, in the handle fixture 1 of the present embodiment, the tip 56 of the handle 55 is beyond the position of the hinge 10 when viewed from the axial direction of the pivot pin 54 of the fixing plate 52, which is the fulcrum of the handle 55 (the front-rear direction of the truck 60). That is, the tip 56 of the handle 55 and the position of the hinge 10 are offset (see symbol g in FIG. 5A). Therefore, when the first fastening portion 20 and the like are rotated from FIG. 5A to the state shown in FIG. Here, the first fastening portion 20 is inclined so that the interference with the handle 55 becomes stronger toward the distal end 21 . Therefore, the greatest external force is required at the moment when the first fastening portion 20 gets over the tip 56 of the handle 55 . For these reasons, the regulated state between the handle 55 and the first fastening portion 20 is reliably maintained in a state in which no external force is applied.

On the other hand, when the handle 55 at the operating end is to be fixed by the handle fixture 1, the reverse of the above description should be performed. Specifically, the first fastening portion 20 and the like are rotated counterclockwise about the axis 12 of the hinge 10 from the state indicated by the dashed line in FIG. Then, an external force is applied to the handle 55, the first fastening portion 20, and the like, and the state shown in FIG. 5B is changed to the state shown in FIG. 5A and then to FIG.

As described above, according to the handle fixture 1 of the present embodiment, the handle 55 can be switched between the regulated state and the non-regulated state by substantially one operation of rotating the first fastening portion 20, the second fastening portion 23, etc. about the hinge 10. In addition, the handle 55 is fastened by two fastening parts, the second fastening part 23 and the first fastening part 20, and even if the second fastening part 23 is disengaged, the first fastening part 20 can keep the handle 55 in a regulated state. This reduces the risk of the handle fixture 1 coming off the handle 55 .

It is also possible to manufacture the handle fixture 1 from the tube 13 of the hinge 10 and several steel bends. For this reason, the structure is simple, failures can be reduced, and the handle fixture 1 can be made excellent in durability. Even if the first fastening portion 20, the extending portion 22, and the second fastening portion 23 are bent or broken, they can be easily repaired by correcting the bending or welding on site.
