7 and 38 are inserted into the holders 35 and 36 through the notches 39 and 39 of the frame body 30 which communicate with the holders 7 and 38, and are slidably accommodated therein.

Reference numeral 41 denotes an operation plate as a component of a linkage mechanism for operating the lock pins 31 and 32 to project and retract, and is slidably mounted on the upper edge step portion 40 of the frame body 30. Guide slits 42 and 43, through which the operation protrusions 33 and 34 of the lock pins 31 and 32 penetrate, are formed in the operation plate 41 in an inverted “H” shape, and the operation plate 41 is shown in FIG.
When it is slid in the arrow C direction, the operation protrusions 33 and 34 are guided obliquely forward along the guide slits 42 and 43, so that the lock pin 31 is in the arrow A direction in FIG. 3 and the lock pin 32 is opposite thereto. Is driven so as to project in the B direction.

In order to facilitate the movement of the operation plate 41,
A guide post 44 is erected in the frame body 30, and a guide hole 45 of the operation plate 41 is fitted into the guide post 44, so that the guide post 44
The top of the is secured by a washer 46 and a clamp ring 47. Reference numeral 48 denotes a return spring that returns the operation plate 41 to the original position after the operation plate 41 has moved in the direction of arrow C, and is hung between the guide post 44 and the lower surface post 49 of the operation plate 41.

On the other hand, the upper plate 10a of the hanger device body 10
On the base (back) of the above, there is provided a lock operation part 50 for entraining the operation plate 41 in the arrow C direction. A part of the lock operating portion 50 penetrates a slit (not shown) of the upper plate 10a and is connected to a driving piece 51 located inside the upper plate 10a. This entrainment piece 51 is the upper plate 10a.

Unlocked state (non-acting state) by retracting from
Becomes In addition, the lock part has a structure that can lock the lock.
However, the structure is not limited to the hole and may be a recess or the like.

Next, the operation will be described. When grasping a can with the above-mentioned can hanger device, the can hanger device is brought above the can, and the upper opening edge of the can is inserted into the claws 21 and 21 of the gripping device 11 and brought into contact with the stopper 25. At this time, the claws 21 and 21 of the gripping device 11 have the coil spring 23.
Since the open / close rod 16 is pressed downward, the open / close rod 16 is fully opened as shown in FIG. Further, the lock pins 31 and 32 are located below the lock holes 54 and 54, and even if the lock operation part 50 is moved in the arrow C direction, the lock pins 31 and 32 are not moved to the inner walls of the side plates 10b and 10b. Cannot be moved to the lock position.

In this state, the grip portion 14 of the can hanger device
When the can hanger device main body 10 and the opening / closing rod 16 are lifted by gripping, the opening / closing rod 16 is moved upward along the shaft portion 19 against the force of the coil spring 23, and each member is moved to the position shown in FIG. It is moved to the grip position shown. That is, nail 2
1, 21 hold the opening edge of the can from both sides. This gripping force increases according to the lifting force applied to the can,
It becomes maximum at the position where the opening / closing rod 16 is raised to the uppermost portion according to the thickness of the upper opening edge of the can.

In any case, at the position where the upper opening edge of the can is gripped, the lock pins 31 and 32 substantially coincide with the lock holes 54 and 54, and the lock operating portion 50 is moved in the arrow C direction to lock the can. It becomes possible to That is, when the lock operating portion 50 is moved in the arrow C direction against the return spring 53, the operation plate 41 resists the return spring 48 due to the engagement of the entrainment piece 51 and the entrainment protrusion 52. Be taken to. The movement of the operation plate 41 is smoothly performed by fitting the guide post 44 and the guide hole 45.

Further, as the operating plate 41 moves, the guide slits 42 and 43 formed in the inverted "H" shape also move in the direction of arrow C, so that the operating projection 3 engaged with the guide slits 42 and 43.
3, 34 are guided toward the side plates 10b, 10b while being guided by the guide slits 42, 43. As a result, the lock pins 31 and 32 penetrate through the lock holes 54 and 54, respectively, and the lock pin 31 moves in the direction of arrow A in FIG.
2 projects in the direction of arrow B. Thus, the locking device is in the locked state, and the pawls 21 and 21 do not separate from the can even when the hand lifting the can hanger device main body is released.

Since the tips of the lock pins 31 and 32 are obliquely cut so as to be short upward and long downward, they work as follows. First, when changing to the locked state as described above, since the tips are sharp, the lock pins 31 and 32 are
From the time when the lock holes 54, 54 almost coincide with each other, the lock holes 54, 54 can be penetrated without any feeling of resistance. On the other hand, when the force of the coil spring 23 is applied downward by releasing the hand, the large area portions of the lower surfaces of the lock pins 31 and 32 engage with the lock holes 54 and 54, so that the locked state can be stably maintained. .

When the can hanger is to be detached from the can, for example, when the can hanger device is attached to another can, the gripping portion 14 is gripped again and the opening / closing rod 16 is slightly lifted with respect to the upper plate 10a. Since the tips of the lock pins 31 and 32 are obliquely cut, the lock pins 31 and 32 are retracted inside the side plates 10b and 10b by being guided by the light slope.
After that, the operation plate 41 returns to the original position only by the force of the return spring 48. At this time, the lock operation part 50 has returned to the original position by the action of the return spring 53, and is not in the position where the movement of the operation plate 41 is hindered. That is, this locking device is provided with the opening / closing rod 16
Just lift a little to automatically return to the unlocked state.

In this state, the grip portion 14 of the can hanger device
Since the opening / closing rod 16 is moved upward when the main body 10 of the hanger device is lifted by grasping, the pair of claws 21 and 21 of the gripping device 11 can hold the upper opening edge of the can at two diametrical positions. In this state, the can can be lifted and transported. Therefore, the attaching / detaching operation is easy, the lifting and carrying work of the can is simplified, the working efficiency is improved, and the risk of injury to the worker can be avoided.

It is to be noted that the present invention is only required to allow the operator to maintain the lock on the upper edge of the gallon can when desired.
The lock mechanism is not limited to the one using the pin. For example, a hook-shaped locking portion may be provided on the upper surface of the open / close can, and the open / close can may be locked by a lock operation part that operates only at the gripping position of the upper plate as in the above embodiment.
Further, although the lock operating portion 50 is provided on the upper plate, it may be provided at another position, for example, the opening / closing rod. Furthermore, although the return spring 53 is used to return the lock operation part 50 to the original position in the above-described embodiment, the lock operation part 50 may be manually returned to the original position without using the return spring 53.

[0027]

As described above, the can hanger device of the present invention is provided with the lock device, and after the upward movement of the opening / closing rod, the lock operation portion of the upper plate is moved to move the grip device to the grip position. Can be locked. Therefore, even if the hand holding the device is released after the lock is applied, the can hanger device does not fall into the can. Further, when the can is reused, it is not necessary to attach the can hanger device again. If you want to get the desired mix of colors from multiple paint gallon cans, you can leave the can hanger device attached to each paint gallon can for those cans with excess paint content. It is convenient to reuse the can and can always be handled integrally with the can, so that the can is easily stored even if there are a plurality of can hanger devices. Further, since the upper end of the transported object can be held by lifting the apparatus main body, the attachment / detachment operation is easy, the working time can be shortened, and the burden on the worker at the time of working can be reduced.
