Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a locking device that is convenient for many users to lock using a padlock brought by themselves, such as a locker installed in a school.

[0002]

[Prior art]

 As a locker for a locker, it is usual to install a lock into the locker itself so that it can be locked or unlocked with a key, and the handle for opening the door is fixed to this door. In many cases, the handle and the handle are provided on a common mounting member and are attached to the door. Moreover, this kind of handle is integrally provided by forming an undercut recess in the mounting member.

[0003]

[Problems to be solved by the device]

 According to the above-mentioned conventional technique, when the lock is broken or the key is lost, it is necessary to replace the entire unit including the lock and the handle, resulting in high management cost. In addition, forming a handle by an undercut recess in the mounting member requires a complicated demolding device for demolding at the time of molding, or requires complicated manual work. There is a disadvantage that the cost for is significantly higher.

Therefore, an object of the present invention is to provide a locking device that can be locked by using a padlock brought by a user, and another object is to reduce the cost for forming a handle. It is to provide a mounting member structure that can be manufactured.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention exposes an operating member having a hook ring and a handle through which a padlock bolt can be penetrated, to one side of a front portion of a mounting member at an intermediate portion between the hook ring and the handle. In this way, with the pivotally stopped shaft, the hanging ring appears and disappears on the front of the mounting member as it swivels, and the bolt of the padlock is penetrated in the protruding state of the hanging ring to retract the hanging ring. In addition to providing a bolt on the mounting member, the operating member is provided with an operating arm for driving the bolt so that the operating arm can lock the bolt when the hanging ring is projected. It was configured like this.

[0006]

[Action]

 You can open the door by hooking the handle on the operating member with your fingertip, and when the handle is pushed in when the operating member is closed, the operating member turns and the latch ring protrudes. The ring is blocked by the bolt so that it cannot retract, and the locked state is maintained due to the removal of the operating member. If the padlock is removed from the door lock from the closed state and the handle is pulled with your fingertip, the hook ring will retract and the door will open. Further, since the handle is provided on the actuating member separate from the mounting member without forming the handle integrally with the mounting member, a mounting member without undercut can be used.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment in which a metal plate locker is equipped. As shown in FIGS. 1 to 4, a vertically rectangular mounting member 3 is fixed in a fitted state near the free end of a door 2 provided on the locker body 1 so as to be openable and closable, and a spring 4 is attached to the back of the mounting member 3. In order to make it easier to always advance, the latch 5 is provided so that its tip engages with the edge 6 of the rocker body 1 when the door is closed, and the plate-shaped bolt 7 is pivotally stopped by the shaft 8. However, the tip of the mounting member 3 is provided so that it can be locked by engaging with the back surface of the edge portion 6 of the rocker body 1 by swiveling, and the front surface portion of the mounting member 3 has a cutout portion 9 in the lower portion. A recessed portion 11 is formed in the upper portion of the recessed portion except for the wall 10, and a grip 12 is provided on the upper portion of the recessed portion 11 on substantially one side thereof, and a hooking ring 13 for the left-right axis is provided on the lower end portion thereof. There is a vertical rectangular substantially plate-like actuating member 14 in the middle part The shaft 15 is stopped by the shaft 15, and the hook ring 13 is projected and retracted in the notch 9 as it turns, and the handle 12 is oscillated in the front-rear direction inside the recess 11. The operation member 14 further extends rearward. The arm 16 is integrally provided, and its front end portion is engaged with the receiving hole 17 formed in the hole 7.

Under the above-mentioned structure, when the lock ring 13 is used regardless of the lock, the hooking ring 13 as shown in FIGS. With the fingertip inserted into the recessed portion 11 of the mounting member 3 while being held in the engaged posture, the latch 5 retracts from the back of the mounting member 3 against the spring 4 by wrapping around behind the handle 12 and pulling it. The door 2 can be opened so that the door 2 can be opened by simply pushing the door 2 to a position where the latch 5 engages with the edge portion 6 of the rocker body 1.

In the case of locking the lock, as shown in FIGS. 2 and 4, from the non-engagement posture in which the hooking ring 13 is recessed in the notch 9 and the operating arm 16 raises the bolt 7, the lock ring 13 is moved from FIG. 1, FIG. As shown in FIG. 6, first, the operating member 14 is swung by pushing the handle 12 with a fingertip to project the hooking ring 13 forward, and the operating arm 16 causes the bar 7 to be attached to the edge 6 of the rocker body 1. After locking the backrest in the lying posture, lock the padlock 18 by inserting the bolt 19 of the padlock 18 into the hanging ring 13 in the protruding state as shown in FIGS. 1 and 6. In the hanging ring 13, the bolts 19 are blocked by the blocking walls 10 on both sides of the notch 9 to prevent the hanging ring 13 from immersing in the notch 9, whereby the working arm 14 of the actuating member 14 falls on the canopy 7. Forcibly maintain 7 Try to keep it locked by. In unlocking, the padlock 18 is removed from the hooking ring 13 and the handle 12 is pulled toward you, so that the actuating member 14 is swung and the actuating arm 16 erects the boot 7 so that the edge of the locker body 1 is raised. It can be detached from the back of No. 6.

By providing the hanging ring 13 in the left-right axial relationship near the lower end of the actuating member 14, the padlock 18 can be stably hung as shown in FIGS. Although the forward protrusion size does not increase as in the case of being held, in the illustrated embodiment, the attachment member 3 at the position corresponding to the back surface of the padlock 18 in the suspended state is further added. A notch 20 is formed in the front edge portion, whereby the amount of forward protrusion of the padlock 18 can be reduced as much as possible.

In addition, since the strength is insufficient in the locked state only with the structure in which the bolt 7 is locked by the shaft 8, the back part of the mounting member 3 receives the middle part of the bar 7 in the locked position from the back. It is desirable to extend the hook-shaped stopper 21. Further, the actuating member 14 is provided with a chevron-shaped cam 22 having the shaft 15 as an axis center, and the actuating member 14 is unlocked or locked while the cam 22 is constantly pressed against the concave portion 11 of the mounting member 3. It is suitable to provide a spring 23 for stabilizing the posture.

[0012]

[Effect of device]

 As described above, according to the present invention, an actuating member having a hook and a handle through which a padlock bolt can be passed is provided at the front side of the mounting member at an intermediate portion between the hook and the handle. While the pivot is locked so that it can be exposed to the outside, the hanging ring appears and disappears on the front surface of the mounting member as it turns, and the bolt of the padlock is penetrated in the protruding state of the hanging ring to retract the hanging ring. The bolt is used to prevent the sinking, and the mounting member is provided with a running bar, and the operating member is provided with an operating arm for driving the running bar. Since it is configured to be in the state, in the case where the lock is broken or the key is lost as in the past, there is no need to replace the entire unit including the lock and the handle. There is an advantage that only the lock needs to be replaced at the user's own expense, and there is no need for replacement work. Therefore, the management cost is extremely low, and the mounting member itself is undercut during molding. Since the handle is provided as a separate member on the actuating member for retracting the hook ring and driving the bolt without forming the handle, a complicated demolding device is not required for demolding at the time of molding, or it is complicated. There is an advantage that the manufacturing cost is remarkably low because no manual work is required.
