The present invention relates to an improvement of a handle lock used in a vending machine or the like. Generally, the handle lock used for a conventional vending machine etc. arranges the cam 52 in the inner end of the cylinder lock 51 inserted in the handle 50, for example, as shown in FIG. The structure of engaging the bar piece 53 in front of (52) was proposed. In the handle lock of such a structure, since the clad piece 53 protrudes only in one direction of the circumference, the handle was inclined easily. In addition, since the cam 52 and the clad piece 53 were arranged in series, it was difficult to shorten the length (thickness) of the steering wheel lock in the depth direction.

In order to solve this problem, a handle lock having a configuration as shown in FIG. 17 is proposed. In this handle lock, an inner case bolt 55 is inserted into the inner circumference of the handle case 54, and a cylindrical portion 56 of the handle is inserted into the inner case bolt 55. The cam 57 is rotatably supported by the cylindrical portion 56 by the inner cylinder 58 of the lock. Moreover, the cladding member 59 is rotatably supported with respect to the shaft 60, and is arrange | positioned so that it can protrude from the protrusion hole 61 formed in the cylindrical part 56 of the handle.

In addition, a lock, for example, a cylinder lock in a handle lock used in a conventional vending machine or the like has been fixed to the cylinder 81a of the handle 81 by a shaped engagement hole 80 as shown in FIG. . This engagement hole 80 is fixed to the cylinder body 81a of the handle 30 with the screw 81b, and the engagement groove 80a squared in the front end is the outer cylinder 82a of the cylinder lock 82. Was engaged with the screw portion 82b. Therefore, this cylinder lock 82 was fixed by this latching | difference opening 80, and was preventing the drawing of the handle 81 from the cylinder 81a.

By the way, in the conventional handle lock shown in FIG. 16 mentioned above, since the splint 53 protrudes only in one direction of the circumference, the handle tends to be inclined, caught on the way, and becomes like a locked state. It was the cause of incomplete lock which protruded by external force. As described above, since the cam 52 is attached to the inner cylinder of the lock, and the latch member 53 is serially engaged in front of the lock 52, the length of the handle lock in the depth direction is shortened. , There was a limit.

In addition, in the example shown in FIG. 17, since the cladding member 59 protrudes on both sides of the cylindrical part of the handle, the inclination of the handle or the like can be prevented, but the cladding member 59 can rotate with respect to the shaft 60. Since it is so supported, it is necessary to largely form the protrusion hole formed in the protrusion hole 61 and the inner case bolt. Therefore, there is a drawback that the mechanical strength of the handle is lowered by decreasing the cross-sectional area at the projecting hole of the cladding member 59. That is, since a large protrusion hole must be formed, the sudden change of the cross-sectional area in this part causes stress concentration, and there exists a possibility that the cylinder body of a handle may be destroyed by the impact from the outside or the hardening by the bar. . Moreover, there was a problem in the waterproofness around the switch attached to the switch mounting hole.

Moreover, in the method of fixing with the locking earth shown in FIG. 18, since the distal end of the locking earth is engaged with a part of the threaded portion of the outer cylinder, it cannot be pulled out by the normal pulling force, There was a problem of being drawn out.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object thereof is to provide a handle lock capable of increasing the strength to increase the fracture resistance and at the same time making the depth deep.

The inner cylinder fixed to the handle 13 and the handle 13 and the cylindrical portion 13a of the handle 13, which are inserted to be accommodated in a portion and protrude outwardly, A lock 15 having a 15a and an outer cylinder 15b, a cam 16 disposed in the cylinder 13a of the handle 13 and rotating in accordance with the rotation of the inner cylinder 13a, and the cam 16; ), It is composed of a pair of cladding members 17 which project linearly in the circumferential direction of the cylinder 13a.

Here, the handle case 11 is formed in a T shape by the cylindrical portion 11a and the attachment portion 11b orthogonal to the cylindrical portion 11a, as shown in FIG. In the inner circumferential portion of the cylindrical portion 11a, a recessed portion 18 to which the latch member 17 engages is formed, while a rear end portion of the inner case bolt 12 is inserted into the rear end portion. 11c) is open. On the other hand, the attaching part 11b is provided with the handle storing part 11d, and is fixed by a screw etc. by facing the back side of the attaching part 11b.

Since the cylindrical part 11f was arrange | positioned around the attachment hole 11e of the handle case 11, and the rubber | gum 27 was arrange | positioned inside this holding part 13b opposing this, the handle 13 was made When stored, the water resistance around the switch mounting portion can be improved. And even if the rubber | gum 27 is not excreted, only the cylindrical part 11f can fully make it constant.

As shown in FIG. 2, the inner case bolt 12 is rotatably mounted in the cylindrical portion 11a of the handle case 11, and has a compression spring 21 for biasing the handle 13 in the protruding direction. Equipped with. In addition, a protruding hole through which the bar member 17 protrudes is drilled.

The handle 13 is roughly T-shaped by a cylinder 13a inserted through the inner case bolt 12 into the cylindrical portion 11a, and a grip portion 13b disposed orthogonally to the cylinder 13a. It consists of. In addition, the compression spring 21 disposed in the inner case bolt 12 is biased in a direction protruding from the handle case 11 and the inner case bolt 12. In addition, the lock 15 is fixed to the lock storing hole 20 at the front of the handle 13 by the fixing bracket 14.

The cam 16 is attached to the inner cylinder 15a rotatably disposed in the lock 15, and the inner cylinder 15a and the cam 160 can be rotated by opening the lock 15. The handle 13 As shown in Figs. 10 and 11 at the rear end of the cylinder 13a, a pair of latch members 17 are disposed, and the springs 24 are urged in a direction that projects linearly from the protruding hole 13c. Here, the cladding member 17 penetrates the protruding hole 13c of the cylindrical body 13a and the protruding hole of the inner case bolt 12 and engages with the recessed portion 18 of the handle case 11.

The cam 16 having the point symmetrical working pieces 16a, 16a linearly retracts the cladding member 17 against the spring 24 in accordance with the rotation of the inner cylinder portion 15a of the lock 15. When the cladding member 17 retreats, as shown in FIG. 4 and FIG. 5, the handle 13 protrudes and becomes rotatable by the biasing force of the compression spring 21. As shown in FIG. At this time, by holding the grip 13b of the handle 13 and turning it, the door of the vending machine can be opened.

As shown in FIGS. 2 to 5, the fixing bracket 14 is inserted at right angles to the insertion direction of the lock 15 into the attachment hole 25 drilled in the front portion of the cylinder 13a of the handle 13. It is. The fixing tool 14 is substantially shaped in cross section, and is disposed to sandwich the locking portion cut in parallel from the both ends of the lock 15 to fix the lock 15. In addition, since the fixing bracket 14 is fixed by a vis outside of the city, it does not fall off by external force such as vibration.

In addition, FIG. 12 shows the handle 104 which engages the locking member 119 of the shape of the nut 117 with the locking part 118 of the nut 117, and prevents the rotation of the nut 117. As shown in FIG.

As shown in FIG. 14, this nut 117 arrange | positions the locking part 118 in the upper and lower parts of the front part, and is equipped with the notch part 117c which the protrusion part 104f of the cylinder 104a abuts on the back part. . In the attaching method of the cylinder lock 105 in which the nut 117 is screwed on, the nut 117 is screwed to the cylinder lock 105 from the outside of the cylinder 104a.

Next, the cylinder lock 105 is inserted into the cylinder 104a. At this time, the bolt 105d of the inner cylinder 105c is matched with the hole 106b of the rotation shaft 106a and the nut 117 is cut. The binding part 117c and the protrusion part 104f of the cylinder 4a are matched and inserted. At this stage, the nut 117 is already prevented from being rotated by the protrusion 104f.

After inserting the cylinder lock 105 into the cylinder 104a in this manner, the locking member 119 of the shape is inserted into the attachment hole 104g of the cylinder 104a to engage with the locking portion 118, and the tip thereof. By inserting into the hole 104a in the lower part of the cylinder 104a, the deformation | transformation of this locking piece 119 itself can be prevented.

Accordingly, the cylinder lock 105 and the nut 117 are drawn off and rotated by the locking piece 119 and the protrusion 114f of the cylinder 104a.

The present invention has been described as an embodiment the handle lock 10 in which the cladding member 17 opens to the outside as described above, but is not limited to the handle lock 10, but is not limited to the type of the cladding member.

Next, the operation of the handle lock 10 configured as described above will be described. First, when the handle lock is opened, the lock 15 is opened with a key and the inner cylinder 15a is rotated. When the inner cylinder 15a rotates, the cam 16 engaged with this rotates. When the cam 16 is rotated, as shown in Figs. 10 and 11, the operating pieces 16a arranged in point symmetry are rotated, and the contact portion 17a of the cladding member 17 is driven against the spring 24. Pull it down.

When the abutting portion 17a is pulled down and the mounting member 17 is retracted, the recessed portion is released from the engagement engagement 12b of the inner case bolt 12 and is formed around the cylindrical portion 11a of the handle case 11. Depart from (18). The handle 13 protrudes forward by the force of the compression spring 21.

When the handle 13 protrudes, as shown in Figs. 5 and 6, the handle 13 and the inner case bolt 12 are rotated integrally and are secured by a bolt or the like fixed to the rear end of the inner case bolt 12. By operating the lock mechanism (not shown), the vending machine can be opened.

When the door of the vending machine is locked, the key is taken out of the lock 15, the handle 13 is returned to a predetermined angle, and then pushed into the handle storing portion 11d of the handle case 11. Then, the cladding member 17 protrudes outwardly from the engagement notch 12b, engages with the engagement notch 12b of the inner case bolt 12 and the recessed portion 18 of the handle case 11, thereby completing the lock. do.

However, even if, for some reason, the indentation of the handle 13 is incomplete, as shown in FIG. 8, the engagement notch 12c in which one side of the cladding member 17 is asymmetrically formed in the inner case bolt 12 is shown. In this way, the handle 13 does not pop out due to vibration or the like. Therefore, although the operator thought that it was locked, even when the handle 13 is not fully stored, since one side of the latch member 17 is engaged with the engagement notch 12c, it is safe without any force acting out.

In this way, since the cladding member 17 is disposed symmetrically by 180 degrees around the center of the shaft, when the handle case 11 is locked, it does not lock or move in an inclined state as in the prior art. . Moreover, since the latch member 17 engages in both the recessed part 18 of the handle case 11 and the engagement notch of the inner case bolt 12, a certain locking effect can be acquired.

In addition, although the above-mentioned embodiment demonstrated the case where the handle 13 protrudes in one step, the shape of the engagement notch 12b formed in the inner case bolt 12 as shown in FIG. 6, FIG. By changing, it can be comprised so that it may protrude in two steps. That is, when the cam 16 is rotated by a predetermined angle, the cladding member 17 moves away from the recessed portion 18 and advances inside the engagement notch 12b to a predetermined position, thereby determining the primary protrusion amount of the handle 13 ( See FIG. 7).

Next, when the cam 16 is rotated again so that the latch member 17 completely retracts from the inner circumference of the inner case bolt 12, the handle 13 protrudes as much as possible by the biasing force of the compression spring 21 ( 5, 6). In this way, by changing the amount of protrusion of the handle 13, it is possible to change the operating portion of the vending machine.

Incidentally, the present invention is not limited to the above embodiments, and various design changes are possible according to the technical idea of the present invention.

As described in detail above, according to the handle lock according to the present invention, a handle case fixed to the door side, an inner case bolt rotatably embedded in the handle case, and housed through the inner case bolt in the handle case, A lock having a handle biased to protrude outwardly, an inner cylinder and an outer cylinder fixed to the fixing bracket in the cylindrical portion of the handle, a cam disposed in the cylinder of the handle and rotating in accordance with the rotation of the inner cylinder; Since it consists of a pair of cladding members which linearly circulate in the circumferential direction of the cylinder by the rotation of, the protrusion of the cylindrical portion of the handle can be made small, thereby preventing the reduction of the cross-sectional area in this portion and increasing the overall strength. You can increase it. Moreover, since the latch member can be disposed right next to the cam member, the depth of the eye can be shortened and the vending machine can be made thin.

Moreover, since the cylindrical part and the rubber | gum were arrange | positioned around the attachment hole, the waterproofness of the switch periphery can be improved. In addition, since the cladding member is disposed symmetrically in the right and left, the cladding protrudes in substantially two symmetry in two directions, so that there is no fear of one-sided operation and the handle does not incline with respect to the handle case.

The cylinder lock is screwed into the nut fixed in the cylinder of the handle, and the rotation lock is inserted into the side of the nut with its one side positioned inside the screw portion, and the one side is formed on the notch of the cylinder lock. Since the rotation of the cylinder lock is prevented by the abutment, it cannot be drawn while the cylinder lock is rotated.

By engaging the engagement pieces on the locking portions on both sides of the nut, it is possible to prevent the nut from rotating and drawing well on both sides of the cylinder lock.
