Description

  The present invention relates to a handle and a to-be-towed object provided with the handle.

  As is well known, a tool box (towed object) used in the field of automobile maintenance is packed with tools made of metal, such as a screwdriver and a wrench, so it must be strong enough to withstand a certain amount of weight. Is done.

  In particular, the handle used when carrying the tool box is fragile because the load of the entire tool box is concentrated, and various devices for improving the strength have been devised from the past. A portable container box is disclosed in which a handle is formed integrally with a lid of a box body.

  However, since the handle of the portable container box disclosed in Patent Document 1 always protrudes from the lid of the box body, the height of the box body increases and becomes bulky. There was a drawback that it was not flat, and it was not possible to put boxes on top of each other and to put tools or sit down during work.

  For this reason, as a storage tool that solves the disadvantages of Patent Document 1, in Patent Document 2, a handle is connected to a tool box by a pair of link mechanisms, and the link mechanism is made of a ring-shaped member. The tip portion positioned on the handle side of the link mechanism is pivotally fixed to the handle and is slidable in the longitudinal direction of the handle, and the tip portion positioned on the tool box side of the link mechanism Is pivoted to the tool box so that the link mechanism rises with the tip positioned on the tool box side as the rotation axis in the state where the handle is pulled, and the link mechanism is in the tool box in a state where the handle is not pulled. There is disclosed a tool box having a structure that falls inward with a tip portion positioned on the side as a rotation axis.

  Patent Document 3 includes a box body (1) formed of a lower metal plate and handles (6) and (6) attached to the center of the upper surface of the box body.

  According to the tool box disclosed in Patent Document 2, the top surface of the tool box becomes relatively flat when the link mechanism falls down and the handle comes into close contact with the tool box without pulling the handle. Although the drawbacks of Document 1 are eliminated, there is a problem that when carrying the tool box, the tool box swings back and forth with respect to the handle following the swing of the arm and lacks stability.

  On the other hand, according to the double spread box disclosed in Patent Document 3, the handle is housed in the handle housing portion, and the top surface of the box becomes flat. Is configured to rotate with the shaft portion of both leg portions fitted and supported in the central reinforcing rod as a rotation shaft, the problem of the Patent Document 2 is also solved, but when the handle is raised Since the state is maintained, there is a problem that when it is desired to flatten the top surface of the box, it is necessary to tilt the handle, and when the top surface of the box is desired, it cannot be used quickly.

  Accordingly, the present inventor has a handle that can withstand a certain amount of weight, can secure stability when carrying a towed object, and is automatically folded compactly by releasing the pulling of the handle. As a technical problem, as a result of repeated trial and error trials and experiments to realize its realization, a pair of handle for attaching the towed object to the grip and the handle to connect the grip to the towed object The tip of the link member positioned on the grip side of the link member is rotatably fixed to the grip and the tip of the link member positioned on the to-be-to-be-triggered object can be rotated with respect to the to-be-to-be-triggered object. The one end of the link member is slidable with respect to the longitudinal direction of the grip, and a pair of gripping members are pulled in a state where the grip is pulled. If there is provided a rotation restricting means for restricting the rotation with the other tip of the pair of link members as the rotation axis so as to maintain the posture in which the link member is inclined in the direction facing each other with the other tip as a base point, to some extent The above technical problem has been achieved by obtaining a remarkable knowledge that a handle that can withstand the weight of the handle and that can be automatically folded compactly by releasing the pulling of the handle is obtained.

  The technical problem can be solved by the present invention as follows.

  That is, the handle according to the present invention is a handle attached to an object to be pulled, and includes a grip and a pair of link members for connecting the grip to the object to be pulled. The tip portion positioned on the towed object side is rotatably fixed to the grip and the tip end portion positioned on the to-be-towed object side is rotatably fixed to one of the link members. The pair of link members are slidable with respect to the longitudinal direction of the grip, and the pair of link members maintain a posture in which the pair of link members incline in directions facing each other with the other tip as a base point. Rotation restricting means for restricting rotation with the other tip of the link member as the rotation axis is provided.

  Further, according to the present invention, in the handle, the rotation restricting means is a protrusion and / or the pair of link members that protrudes in directions facing each other from the tip portions that are pivotally fixed to the grips of the pair of link members. It is a protrusion which protruded toward the opposite direction to the direction which mutually faces from the front-end | tip part rotatably fixed with respect to the to-be-towed object.

  Further, according to the present invention, in any one of the above-described handles, the grip is attached to the to-be-towed object so as to undulate in the vertical direction.

  Further, according to the present invention, the object to be pulled in any one of the handles is a tool box.

  Moreover, this invention is a to-be-towed object provided with one of the said handles.

  According to the present invention, the distal end portion positioned on the grip side of the link member is pivotally fixed to the grip, and the distal end portion positioned on the to-be-to-be-triggered object is pivoted with respect to the to-be-triggered object. It is configured so that one end of the link member can be slid with respect to the longitudinal direction of the grip, and the pair of link members incline in a direction facing each other with the other end as a base point when the grip is pulled. Since the rotation restricting means for restricting the rotation with the other tip of the pair of link members as the rotation axis is provided so as to maintain the link, the direction in which the link members face each other by the weight of the grip when the pulling of the grip is released. When the towed object is carried around, the towed object swings back and forth with respect to the handle. There increased stability is suppressed.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

As a result, when the pulling of the grip 49 is released, the link members 50 and 50 fall down in a direction facing each other due to the weight of the grip 49, and the handle 3 is automatically stored in the handle storage portion 48.

  In the above-described embodiment, the handle according to the present invention is employed in a double door type tool box, but it can also be employed in a single door type tool box. In this case, one handle may be fixed to the top surface of the box lid.

  Note that, as the rotation restricting means according to the present invention, a wall formed on the to-be-towed object to which the link member is connected may be employed. When the link member rotates to a certain degree around the tip of the to-be-drawn object side as a rotation axis, the link member moves outward (in the direction facing the other link mechanism). It is positioned so that the surfaces facing in the opposite direction are in contact. As a result, in the state where the handle is pulled, the respective link members constituting the pair of link mechanisms have the distal end portion of the link member as a rotation shaft so as to maintain the posture in which the link members are inclined in directions facing each other with the distal end portion as a base point. Rotation is regulated. Further, as the rotation restricting means according to the present invention, a wall formed on the grip to which the link member is connected may be adopted. In this case, the wall is outward from the grip (facing the link mechanism on the other side). When the link member rotates to a certain degree with the grip side tip as the rotation axis, it faces the inside of the link member (the direction facing the link mechanism on the other side). Are positioned so that they touch. As a result, in the state where the handle is pulled, the respective link members constituting the pair of link mechanisms have the distal end portion of the link member as a rotation shaft so as to maintain the posture in which the link members are inclined in directions facing each other with the distal end portion as a base point. Rotation is regulated

In each said embodiment, although the tool box was illustrated as a to-be-towed object, the handle | steering-wheel structure which concerns on this invention can be applied also to another container, without being limited to a tool box.
