Description

  The present invention relates to improvement of stays.

JP-A-11-324462 (Patent Document 1)

Various proposals have been made for a stay that is attached to a building, a container, or a power distribution box so that the door is fixed in a predetermined open state.
However, it cannot be said that a method for simply performing such fixation has been sufficiently studied.

For example, a staging device with a stopper mechanism found in the above-mentioned Patent Document 1 has been proposed.
This staging device with a stopper mechanism has a guide cylinder rotatably attached to a fixed frame by a guide cylinder mounting bracket, one end rotatably attached to the door by a slider mounting bracket, and the other end in the guide cylinder 3. The inserted slider, the cylinder fixed to the upper side of the side surface of the guide cylinder, the stopper-support rod fixedly inserted into the cylinder, and urged by the compression spring in a direction protruding into the guide cylinder, A stopper whose tip is engaged with or disengaged from the lock hole of the slider, a cam plate whose base end is connected by a pivot to a portion protruding from the cylinder of the stopper support rod, and a wire-mounting shaft whose upper end is connected to the tip of the cam plate It is composed of an operation wire with a finger ring attached to the lower end, and the cam plate rotates around the pivot axis so that one surface of the base end of the cam plate When abutting the loaders of the head, while the stopper escapes from the lock hole, when the other surface of the proximal end portion of the cam plate abuts on the head, in which the stopper is engaged with the lock hole.

  In the staging device with a stopper mechanism disclosed in Patent Document 1, the stopper is engaged with the lock hole of the slider, so that the slider is prevented from moving with respect to the guide cylinder, and the door is at a predetermined opening angle. It is held fixed. The engagement state between the stopper and the lock hole is maintained by the bias of the compression spring. At this time, the cam plate connected to the stopper-support bar is attracted to the head of the cylinder by the action of the compression spring, and is in contact with the head at the other surface of the base end.

When the finger ring of the operation wire is pulled downward from this door open state, the cam plate rotates clockwise around the pivot, and one surface of the base end portion of the cam plate contacts the head of the cylinder. Since the distance between the pivot and one surface is set to be sufficiently longer than the distance between the pivot and the other surface, the stopper is pulled into the cylinder against the bias of the compression spring. Therefore, the tip of the stopper comes out of the lock hole of the slider, and the slider is unlocked. Then, when the door is closed and rotated around the hinge shaft, the slider is housed in the guide tube. Thereafter, when the hand is released from the finger ring, the stopper is fixed in a state of being pressed against the side surface of the slider by the compression spring.
In this way, the purpose of the stay is to fix the open state of the stay in the opened state of the door without extending the back by the operation of the finger ring of the operation wire.

However, the stay stopper mechanism (lock mechanism) specifically shown in Patent Document 1 includes a cylinder, a stopper accommodated in the cylinder and corresponding to the lock hole, a compression spring accommodated in the cylinder, It is a complicated structure composed of many members such as a stopper support bar provided on the stopper and a cam plate. Therefore, it takes time for manufacturing, and the number of parts and the number of manufacturing / assembling processes increase the manufacturing cost.
Also, if an operator unexpectedly hits or gets caught on the finger ring attached to the operation wire, the stopper is unlocked unintentionally, which is dangerous.

  In view of the above problems, the present invention provides a stay including a lock mechanism that can securely lock the stay with a simple structure, and solves the above problems.

The first device of the present application provides a door that is pivotally attached to an opening of a building or a storage container and adopts the following configuration in a stay that fixes the door in a predetermined open state.
That is, the stay includes a first base material 1 attached to one of the opening and the door, a second base material 2 attached to the other of the opening and the door, and the first base. A connecting member 3 that connects the material 1 and the second base member 2 and can bend and stretch as the door rotates, and a lock mechanism 4 that maintains the bent and stretched state of the connecting member when the door is in the predetermined open state. Is provided. The connecting member 3 includes a superposed portion and a polymerized portion, and the superposed portion overlaps with the polymerized portion at least when the door is in the predetermined open state due to bending and stretching of the connecting portion. . The lock mechanism 4 includes a first insertion portion provided in the overlapping portion, a second insertion portion provided in the overlapped portion, and an inserter. When the overlapping portion and the portion to be polymerized overlap as described above, the inserter is inserted into both the first insertion portion and the second insertion portion, thereby overlapping the polymerization portion and the portion to be polymerized. It fixes to a state and the said open state is maintained.
The above storage container includes a building represented by a house or a building, and also includes a container, a distribution box, a storage room, a basket, and other containers.

  In the second device of the present application, in the first device of the present application, the connecting member 3 is connected to the first link member connected to the first base material 1 and the second base material 2 and A second link member pivotally fixed to the first link member and a locking mechanism are provided. At least one of the connecting portion between the first base material 1 and the first link member and the connecting portion between the second base material 2 and the first link member rotates the base material and the link member. It is movably connected. The connecting member 3 is bent and stretched by opening and closing the second link member with respect to the first link member by relative rotation of the second link member with respect to the first link member. Furthermore, the first link member includes the overlapping portion, and the second link member includes the overlapped portion. The locking mechanism includes a female part provided in one of the superposed part and the polymerized part, and a male part provided in either the superposed part and the polymerized part and capable of fitting into the female part. A part. By overlapping the overlapped portion and the portion to be polymerized by the rotation of the second link member relative to the first link member, the male portion is forcibly fitted to the female portion, and the door is in the predetermined open state. It is possible to lock with. The second insertion portion is arranged at a position corresponding to the first insertion portion in the locked state, and allows the insertion member to be inserted into both insertion portions. Fix the locked state.

  In the third device of the present application, in the second device of the present application, the polymerized portion and the polymerized portion overlap each other. The first and second insertion portions are through-holes that penetrate the polymerized or polymerized portions in the vertical direction, respectively. The insert is formed separately from the overlapping portion and the portion to be polymerized, a shaft portion that can be inserted into both the insertion portions, and a hook portion provided at the upper end of the shaft portion. Is provided. The hook portion is a protruding portion that protrudes in a direction intersecting the axial direction of the shaft portion and cannot be inserted into both insertion portions. When both insertion parts are in corresponding positions, when the shaft part is inserted into both insertion parts from above the polymerization part and the polymerized part, the hooking part is caught on the surface of the polymerization part or the polymerized part and inserted. This prevents the child from falling through the insertion parts downward.

In the fourth device of the present application, in the third device of the present application, the inserter is made of metal and attached to the stay via a string-like body such as a chain.
In addition, a string-like body here is an elongate body without the self-supporting property formed in the shape of a wire other than a chain, such as a wire, leather, resin, or cloth.

  In the fifth device of the present application, in the fourth device of the present application, the overlapping portion of the first link member is at least two sheets of an upper plate member and a lower plate member arranged at intervals in the vertical direction. It is comprised by the plate-shaped member. The second link member is pivotally fixed to the upper plate member and the lower plate member, and is positioned between the upper plate member and the lower plate member in the vertical direction. Comprises the polymerized portion on the side opposite to the second base material with the shaft stop portion interposed therebetween. The female part is a recessed part provided at each of the corresponding positions of the opposing surfaces of the upper and lower plate-like members, and the male part is a hemispherical protrusion that protrudes above and below the polymerized part. By opening the door, the second link member is rotated relative to the first link member toward the predetermined open state, and the first link member is forcibly forced by the two protrusions. It is possible to push the space between the upper plate-like member and the lower plate-like member that constitutes and to insert the protrusion between the upper and lower plate-like members. When both protrusions enter the respective recessed portions, the space between the two upper and lower plate-like members that are spread out becomes narrower toward the original state, and the above-described locked state is obtained.

  In the first to fifth devices of the present application, the lock mechanism of the stay is simply referred to as a first insertion portion provided in the overlapping portion, a second insertion portion provided in the overlapped portion, and an inserter. With this configuration, it can be manufactured easily and at low cost. On the other hand, it is possible to lock (fix) the predetermined opening / closing state (the bending state of the connecting member) of the stay by a simple operation of passing the inserter through both the first insertion portion and the second insertion portion. Does not require a lock operation.

  In addition, in the second to fifth inventions of the present application, a locking mechanism for locking the stay in a predetermined open / closed state is provided separately from the locking mechanism, and malfunction of the locking mechanism such as dropping of the insert occurs. However, since the predetermined open / close state is not immediately released, it is safe. Also, by providing such a locking mechanism separately from the lock mechanism, when a force against the lock is applied to the lock mechanism, it can be distributed to the lock mechanism, reducing the load on the lock mechanism. In addition, the locking mechanism can easily align the insertion portion of the lock mechanism, and the lock operation can be performed smoothly.

  Furthermore, in the third to fifth devices of the present application, the stay can be locked by a simple operation of dropping the inserter (the shaft portion thereof) into the overlapping first and second insertion portions from above. . When locking, the operator may need to extend the back, but if the inserter is dropped into the insertion part as described above, the hooking part will be caught by the overlapping part or the part to be polymerized, and unnecessary insertion will occur. It does not enter the part or drop out from the insertion part. Since the inserter can be inserted by such a simple operation, the locking operation can be completed without struggling even when the back is stretched. In addition, once the inserter is inserted into the insertion part, the inserter cannot be removed unless a force is applied in the direction opposite to gravity (upward), so the stay can be securely locked against the simplicity of the structure. can do.

Furthermore, in the fourth or fifth invention of the present application, since the inserter formed separately is attached to the stay with a string-like body, there is no fear of losing it.
Furthermore, the fifth device of the present application can provide more specific means for realizing the above-described locking mechanism.
