Description

  The present invention relates to a key holder, and more particularly to a key holder that can prevent a key supported by the key holder from being oriented perpendicular to the surface of the key holder when the key holder is suspended in a panel surface.

Lockers in offices, library door keys, desk drawer keys, etc. are collectively managed by the department in charge. This management is performed by storing each key attribute in a key management case in a state where it can be grasped at a glance.
Patent Document 1 discloses a key management case including a case formed with the front side as a slot, and a key holding device attached to a panel located in the case. The key holding device is configured such that a hook can be attached to a groove provided on the front side, and a key holder can be hooked and held on the hook.
Japanese Patent Publication No. 45-23999

However, since the key holder disclosed in Patent Document 1 is configured to support the key so as to be suspended from the lower part of the key holder, the vertical dimension for supporting one key is set to be long. This causes a disadvantage that the storage efficiency of the key management case is lowered.
In this case, it is only necessary to support the key so that the key is positioned on the rear surface side of the key holder. However, simply adopting such a configuration makes the direction of the key orthogonal between the key holder surface and the panel surface. In such a case, there is a disadvantage that it becomes difficult to see the display surface when a display indicating the attribute of the key is attached to the front surface of the key holder.
Therefore, if the gap between the key holder and the panel is set large, it is possible to keep the display in an easy-to-see position even if the above-described orthogonal orientation of the key occurs. Another inconvenience of increasing the thickness direction (depth) dimension is caused.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences. The purpose of the present invention is to make the key orthogonal to the surface of the key holder when the key holder is supported on the rear surface side of the key holder. An object of the present invention is to provide a key holder that effectively prevents the orientation and that is suitable for setting a small dimension between a support portion of the key holder and a panel for forming a region that supports the key holder.

In order to achieve the above object, the present invention provides a key holder for suspending and holding a key on a hook portion provided in a surface of a panel or a wall,
A plate-like portion positioned substantially parallel to the surface of the panel or wall when suspended from the hook portion, a key ring support portion provided such that a key is located on the rear surface side of the plate-like portion, and the key ring A posture adjustment unit that adjusts the direction of the key supported by the support unit,
The posture adjusting unit is configured by a protrusion that extends in the vertical direction of the rear surface of the plate-like part .

  Moreover, it is preferable that the said protrusion part protrudes with respect to the surface of the said plate-shaped part via an inclined part, and is made into a shape.

  In addition, the terms indicating the direction or position in the present specification, for example, “front”, “back”, “left”, “right”, etc. are based on the case where the lid shown in FIG. 1 is viewed from the front side. Used.

According to the present invention, by adopting the configuration including the posture adjustment unit that adjusts the direction of the key on the rear surface side of the plate-like portion, the posture is such that the key is orthogonal to the surface of the plate-like portion. Can be prevented. Therefore, for example, when the key holder is held on the panel surface via the hook portion, the front surface of the plate portion is positioned in a substantially vertical plane even if the space between the plate portion and the panel surface is narrow. Thus, there is no inconvenience that it is difficult to see the display indicating the key attribute.
Moreover, since the said attitude | position adjustment part can be comprised by providing a protrusion part in the rear surface of a plate-shaped part, a structure is not complicated.
Further, if the protruding portion protrudes through the inclined portion, the outer peripheral edge of the key slides on the inclined portion and the plate-like portion even if the key is positioned in the orthogonal direction on the rear surface side of the plate-like portion. It is possible to promote the operation of trying to be parallel.

However, the drop off of the key holder H is regulated.

  The key ring support portion 56 is formed so as to open in the direction perpendicular to the paper surface in FIG. 10B, that is, in the width direction of the plate-like portion 55. Further, as shown in FIG. 11, the posture adjusting unit 58 is configured by a ridge portion 60 extending along the longitudinal direction (vertical direction) of the plate-like portion 55. It has a shape that rises with respect to the surface of 55 via the inclined portion 60A.

  As shown in FIGS. 2 and 12 to 14, the panel 24 has one end in the width direction so that one end in the width direction (the left end in FIG. 2) can rotate in the front-rear direction. The right end side in the figure is supported in the case body 12 via the rotation support portion 64. The rotation support portion 64 is provided on a pair of upper and lower arms 65 and 66 whose one ends are attached to the upper and lower sides of the other end in the width direction (rotation fulcrum side), and the top wall 19 and the bottom wall 17 of the case body 12. And a pair of upper and lower support shafts 68 and 69 for rotatably supporting the other ends of the upper and lower arms 65 and 66 in a plane. Further, a pair of upper and lower cover members 70 and 71 that can be rotated in accordance with the rotation operation of the panel 24 are supported by the support shafts 68 and 69, and the cover members 70 and 71 are connected to one end side of the panel 24 ( When the free end) is pulled forward from the loading / unloading port 11, it moves so as to straddle between the upper and lower portions on the pivot fulcrum side and the top wall 19 and the bottom wall 17 of the case body 12. When the panel 24 is returned into the case main body 12, it is provided so as to retract to the lower surface side of the top wall 19 and the upper surface side of the bottom wall 17.

The arms 65 and 66 are set so as to be located within the surface of the cover member 70. Further, the cover members 70 and 71 are provided in a vertically symmetrical shape and are provided with flat portions 70A and 71A having a substantially fan shape in plan view, and are formed on both sides extending between the central angle side and the end of the arc . The straight portion 72 is formed with a bent portion 74 that engages with the arms 65, 66 when the arms 65, 66 rotate in a plane.

  Next, the attaching / detaching procedure of the key holding device 15 in the key management case 10, the operation of supporting the key K, and the operation of the cover members 70 and 71 when the panel 24 is put in and out will be described.

  First, when attaching the key holding device 15 to the panel 24, the intermediate member 25 is attached to the rear surface side of the key hanger 26 in advance. This attachment can be performed by fitting the standing surface 40 and the hanging surface 44 of the intermediate member 25 to the receiving portions 50 and 51 of the hanger body 47, respectively. The intermediate members 25 may be attached one by one on both sides of the key hanger 26 in the longitudinal direction, but may be additionally attached therebetween.

With the intermediate member 25 attached to the key hanger 26 as described above, as shown in FIG. 8A, the key hanger 26 (not shown) is held in the hand and the intermediate member 25 is directed to the panel 24 side. Then, as shown in FIG. 5B, the upper engaging portion 35 side is inserted into the upper engaged portion 27, and the upper claw 42 is hooked on the step portion 31A.
Next, as shown in FIG. 3C, the lower engaging portion 36 is inserted into the lower engaged portion 28. When the lower engaging portion 36 is to be inserted into the engaged portion 28, the lower pawl 45 positioned rearward of the surface of the body portion 33 of the intermediate member 25 forms the stepped portion 31 </ b> A. In order to be in contact with the upper end, the main portion 33 is elastically deformed so that the lower portion 36 is also contracted while the main portion 33 is accompanied by a bow-like elastic deformation so as to shorten the distance between the upper portion 35 and the lower portion 36.
Therefore, by pressing the key hanger 26 toward the panel 24 so as to push in the main body 33, the upper claw 42 and the lower claw 45 get over the upper and lower non-penetrating portions 31 respectively and engage with the step portion 31A. The positioning member 38 is fitted into the position restricting portion 29 (see FIG. 8D). Thereby, the upper claw 42 and the lower claw 45 are restricted from moving forward by the step portion 31A, and the movement of the upper claw 42 and the lower claw 45 is restricted by the fitting of the positioning member 38 and the position restricting portion 29. Become.
When removing the key hanger 26 from the panel 24, the key hanger 26 may be lifted to perform the operation opposite to the above operation.

The operation of hooking the key holder H, on which the key K is supported via the key ring KR, onto the key hanger 26 is performed so that the key K is located on the rear side of the key holder H as shown in FIG. 53 is hooked on the upward piece 48 </ b> A of the hook portion 48. When the proceeds are inserted into the insertion hole 3 of the upward piece 48A (see FIG. 16), the relationship between the length L and the thickness T of the aforementioned, inserted subsequent is restricted by contact with the falling regulating portion 52 It will be.
Here, when the force to insert is forcibly applied, the lower forming edge 53B gets over the drop-off restricting portion 52 with a click operation (see FIG. 17).

  At this time, since the key K is supported by the key holder H through the key ring KR, the key K is sandwiched between the key holder H and the panel surface in a direction substantially orthogonal to the surface of the key holder H. As a result, the key holder H is inclined and it is difficult to see the display of the heading piece 59. In the present embodiment, since the ridge portion 60 constituting the posture adjusting portion 58 is formed on the rear surface side of the plate-like portion 55 of the key holder H via the inclined portion 60A, the key K is placed on the inclined portion 60A. The outer peripheral edge is forced to slide so that the key K rotates in the vertical plane and becomes substantially parallel with the key holder H, and is positioned in the substantially vertical plane while avoiding the pinched state. Therefore, the display of the heading piece 59 is easily visible from the front side by making the key holder H face the front side (see FIGS. 18 and 19).

Even if the key holder H that is completely supported by the hook portion 48 is turned upside down for some reason, the key holder H may come out of the hook portion 48 due to the presence of the drop-off restricting portion 52. There is no inconvenience.

By the way, when the key holding device 15 is arranged on the rear surface side of the panel 24 or when the key holding device 15 is arranged using the front surface of the rear wall 20, the panel 24 is put in and out of the case body 12. 11 must be pulled forward (see FIG. 22). This pull-out operation can be performed by an operation of picking and pulling the handle 80 attached to the lower part of the front surface on the free end side of the panel 24.
When the pulling operation force is applied, the panel 24 becomes rotatable via the arms 65 and 66 rotatably attached to the support shafts 68 and 69, and the cover members 70 and 71 maintain the retracted position (see FIG. 20). In this state, the panel 24 and the arms 65 and 66 are rotated in advance (see FIG. 21). When the rotation angle further advances, the arms 65 and 66 are engaged with the bent portion 74 located on the front side of the cover members 70 and 71, and the cover members 70 and 71 are pulled by the engagement and the top wall 19 is engaged. And it moves so that it may straddle between the upper end and lower end of the rotation fulcrum side of the panel 24 (see FIG. 22).

  Therefore, in this state, when the panel 24 drawn out to the near side is to be returned to the case body 12, the cover members 70 and 71 are present on the pivot fulcrum side like a baffle plate. Therefore, there is no room for the fingertip to enter the part, and the inconvenience of pinching the fingertip during the return operation can be avoided. In the initial stage of returning the pulled-out panel 24, the cover members 70 and 71 maintain the position shown in FIG. 22, and when the return angle exceeds a certain value, that is, the arms 65 and 66 are When engaged with the bent portion 74 on the depth side, the arm 65, 66 follows the rotation operation of the arm 65, 66 and rotates to return to the original retracted position.

Therefore, according to such an embodiment, even if the key management case 10 is dropped in a state where the key hanger 26 is mounted on the panel 24, the key hanger 26 panel 24 is inadvertently dropped. In addition, there is an effect that the state supported by the hook portion 48 can be stably maintained without dropping the key holder H.

Further, key hanger 26, since the upper engaging portion 35 and the lower engaging portion 36 by the main body portion 33 of the intermediate member 25 is elastically deformed in which mutually relates respectively to the engaging portion 27, the key hangers 26 when removable It is not necessary to move the key hanger greatly in the vertical direction, and there is no problem even if the key hanger 26 is attached to the position closest to the upper end of the panel 24. Therefore, effective use within the panel 24 surface can be achieved.

  Furthermore, since the direction of the key K can be adjusted when the key holder H is supported on the hook portion 48, the dimension between the panel 24 and the position where the key holder H is suspended can be set small, and the thickness of the key management case 10 can be reduced. Directional space can also be used effectively.

  Further, since the cover members 70 and 71 are provided so as to be positioned between the pivot fulcrum side and the top wall 19 when the panel 24 is pulled out to the front of the insertion / removal port 11, the panel 24 rotates when the panel is stored. The danger that the fulcrum side pinches the fingertip can also be avoided.
