Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional operation panel as described above, it is necessary to provide protrusions on the front plate. Therefore, when using a resin front plate, the protrusions can be easily formed. However, for example, when using a front plate made of a stainless steel plate, the processing of the front plate becomes complicated.

[0005] This disclosure has been made to solve the above problems, and an object thereof is to obtain an elevator landing operation panel that can facilitate the attachment and detachment of the face plate to the button case and can facilitate the production of the face plate regardless of the material constituting the face plate.

Means for Solving the Problems

[0006] The elevator landing control panel according to this disclosure comprises a button case installed at the landing and a faceplate that covers the front of the button case. The faceplate has a plate body that is superimposed on the front of the button case, a hook portion provided at the upper end of the plate body that hooks onto the upper end of the button case, and a lower end bend portion that protrudes upward from the lower end of the plate body. The lower end of the button case is provided with a holding portion that is inserted between the lower end bend portion and the plate body and prevents the lower end bend portion from being displaced forward of the button case, thereby holding the faceplate on the button case. The holding portion has an elastically deformable portion that can be elastically deformed in the width direction of the button case, and a claw portion that is inserted between the lower end bend portion and the plate body. By elastically deforming the elastically deformable portion of the holding portion and pulling out the claw portion from between the lower end bend portion and the plate body, the faceplate can be removed from the button case. [Effects of the Invention]

[0007] According to the elevator landing control panel of this disclosure, it is possible to easily attach and detach the faceplate to the button case, and to easily manufacture the faceplate regardless of the material that makes up the faceplate. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1. FIG. 1 is a front view showing an elevator landing according to Embodiment 1. In the figure, a landing entrance 11 is provided in the landing. The landing entrance 11 is opened and closed by a pair of landing doors 12. A hall lantern 13 and a landing operation panel 20 are provided on the landing wall 10.

[0010] FIG. 2 is a front view showing an enlarged view of the landing operation panel 20 in FIG. 1. FIG. 3 is a side view showing the landing operation panel 20 in FIG. 2.

[0011] The landing operation panel 20 has a button case 21, a face plate 22, a substrate, and a pair of call buttons 23.

[0012] The button case 21 is installed on the landing wall 10. The button case 21 is made of resin.

[0013] The face plate 22 is covered on the front surface of the button case 21. The face plate 22 covers the entire front surface of the button case 21 so that the button case 21 is not exposed to the landing. The face plate 22 is made of a stainless steel plate. A pair of button holes 22a are provided in the face plate 22.

[0014] The substrate is housed in the button case 21. The pair of call buttons 23 are mounted on the substrate. The pair of call buttons 23 are passed through the pair of button holes 22a and protrude slightly toward the landing side from the front surface of the face plate 22. The pair of call buttons 23 are operated by elevator users.

[0015] FIG. 4 is a side view showing the face plate 22 in FIG. 1. FIG. 5 is a perspective view showing the upper back surface of the face plate 22 in FIG. 4. FIG. 6 is a perspective view showing the lower back surface of the face plate 22 in FIG. 4.

[0016] The faceplate 22 has a plate body 22b, a hook portion 22c, and a lower end bent portion 22d.

[0017] The plate body 22b is placed on top of the front of the button case 21. A pair of button holes 22a are located in the center of the plate body 22b. The portion of the plate body 22b between the upper and lower ends is flat. The upper and lower ends of the plate body 22b are slightly curved toward the button case 21.

[0018] The hook portion 22c is provided at the upper end of the plate body 22b. The hook portion 22c is formed by bending the upper end of the plate body 22b downwards. The hook portion 22c can be hooked onto the upper end of the button case 21.

[0019] The lower end bent portion 22d protrudes upward from the lower end of the plate body 22b. The lower end bent portion 22d is formed by bending the lower end of the plate body 22b upward. The lower end bent portion 22d is also located opposite the lower back surface of the plate body 22b.

[0020] As shown in Figure 6, the dimension W1 of the lower end bend portion 22d in the width direction of the faceplate 22 is smaller than the dimension W2 of the plate body 22b in the width direction of the faceplate 22. The lower end bend portion 22d is formed in the center of the faceplate 22 in the width direction.

[0021] Figure 7 is a front view showing the button case 21 of Figure 3. Figure 8 is a side view showing the button case 21 of Figure 7. Figure 9 is a perspective view showing the upper rear of the button case 21 of Figure 7. Figure 10 is a cross-sectional view along line XX of Figure 9.

[0022] An insertion portion 21a is formed at the upper end of the button case 21, onto which the hook portion 22c is hooked. The insertion portion 21a is inserted inside the hook portion 22c.

[0023] A pair of retaining portions 21b are provided at the lower end of the button case 21. The pair of retaining portions 21b are spaced apart from each other in the width direction of the faceplate 22. Furthermore, the pair of retaining portions 21b are provided symmetrically with respect to the center of the button case 21 in the width direction.

[0024] Figure 11 is a front view showing an enlarged view of one of the pair of retaining parts 21b in Figure 7. Figure 12 is a perspective view showing the retaining part 21b in Figure 11.

[0025] Each of the pair of retaining parts 21b has an elastically deformable part 21c, a claw part 21d, and a projection part 21e.

[0026] The elastically deformable portion 21c is elastically deformable in the width direction of the button case 21. That is, the elastically deformable portion 21c functions as a leaf spring.

[0027] The claw portion 21d is provided at the lower end of the holding portion 21b. The claw portion 21d is also inserted between the lower end bending portion 22d and the plate body 22b.

[0028] The projection 21e is provided between the elastically deformable portion 21c and the claw portion 21d. The projection 21e also protrudes from the elastically deformable portion 21c toward the center in the width direction of the button case 21. The projection 21e is pressed when the elastically deformable portion 21c is elastically deformed outward in the width direction of the button case 21.

[0029] Figure 13 is a perspective view showing the upper rear of the landing control panel 20 in Figure 3. Figure 14 is a cross-sectional view along the line XIV-XIV in Figure 13. When the faceplate 22 is attached to the button case 21, the hook portion 22c is hooked onto the insertion portion 21a.

[0030] Figure 15 is a perspective view showing the lower rear of the landing control panel 20 in Figure 3. Figure 16 is a cross-sectional view along the line XVI-XVI in Figure 15. The button case 21 is configured to allow access to a pair of retaining parts 21b from the rear side.

[0031] When the faceplate 22 is attached to the button case 21, the button case 21 is positioned between the two ends of the faceplate 22 in the width direction, and the faceplate 22 is prevented from being displaced in the width direction of the button case 21 by the button case 21.

[0032] Furthermore, when the faceplate 22 is attached to the button case 21, the claws 21d of the pair of retaining parts 21b are inserted between both ends of the lower bent portion 22d in the width direction of the faceplate 22 and the plate body 22b. This prevents the lower bent portion 22d from being displaced forward of the button case 21. At this time, the hook portion 22c is hooked onto the insertion portion 21a, so the faceplate 22 is held on the button case 21 by the pair of retaining parts 21b.

[0033] Figure 17 is an explanatory diagram showing how to remove the faceplate 22 from the button case 21 as shown in Figure 15. The elastically deformable portion 21c of at least one of the pair of retaining portions 21b is elastically deformed outward in the width direction of the button case 21 as shown by the arrow in Figure 17, thereby pulling out the claw portion 21d from between the lower end bent portion 22d and the plate body 22b.

[0034] This releases the faceplate 22 from being held by the pair of retaining parts 21b, allowing the lower end of the faceplate 22 to move forward towards the button case 21. After this, the faceplate 22 can be detached from the button case 21 by sliding it upward and removing the hook part 22c from the insertion part 21a.

[0035] When attaching the faceplate 22 to the button case 21, the hook portion 22c should be hooked onto the insertion portion 21a, and then each claw portion 21d should be inserted between the lower end bent portion 22d and the plate body 22b.

[0036] When the landing control panel 20 is not installed on the landing wall 10, the operator can access the pair of retaining parts 21b from the back side of the button case 21 and attach or detach the faceplate 22 to the button case 21.

[0037] On the other hand, when the landing control panel 20 is installed on the landing wall 10, it is not possible to access the pair of retaining parts 21b from the back side of the button case 21.

[0038] Therefore, when the landing control panel 20 is installed on the landing wall 10, a jig 31 is used to press the projection 21e, as shown in Figures 18 and 19. A jig opening 20a into which the jig 31 can be inserted is provided between the plate body 22b and the lower end of the button case 21.

[0039] To remove the faceplate 22 from the button case 21, the jig 31 is inserted into the button case 21 through the jig opening 20a. Then, as shown in Figure 20, by tilting the jig 31 and pressing the projection 21e with the jig 31, the elastic deformation portion 21c is elastically deformed, and the claw portion 21d is pulled out from between the lower end bent portion 22d and the plate body 22b. For example, a steel ruler can be used as the jig 31.

[0040] Here, it is preferable that the button case 21 is configured so that the holding state of the faceplate 22 by the holding portion 21b can be released by the jig 31 only when the jig 31 having dimensions within a set range is inserted into the jig opening 20a.

[0041] Figure 21 is an explanatory diagram showing a state in which a flat plate 32 with a thickness larger than the set range is inserted into the jig opening 20a. In this case, the tip of the flat plate 32 hits the perimeter of the jig opening 20a, and it is not possible to insert the flat plate 32 any further into the button case 21. Therefore, the elastic deformation portion 21c cannot be elastically deformed outward.

[0042] Figure 22 is an explanatory diagram showing a state in which a flat plate 33 with a width dimension smaller than the set range is inserted into the jig opening 20a. In this case, even if the flat plate 33 is tilted, the flat plate 33 cannot push the projection 21e. Therefore, the elastic deformation portion 21c cannot be elastically deformed outward.

[0043] Figure 23 is an explanatory diagram showing a state in which a flat plate 34 with a width dimension larger than the set range is inserted into the jig opening 20a. In this case, the tip of the flat plate 34 hits the projection 21e, and the flat plate 34 cannot be inserted any further into the button case 21. Therefore, the elastic deformation part 21c cannot be elastically deformed outward.

[0044] Figure 24 is an explanatory diagram showing the state in which the dedicated jig 35 is inserted into the jig opening 20a. The tip of the dedicated jig 35 is provided with an inclined surface 35a that contacts the projection 21e. Therefore, even if the width dimension of the dedicated jig 35 is the same as the width dimension of the jig opening 20a, by pushing the dedicated jig 35 into the jig opening 20a, the projection 21e is pushed outward by the inclined surface 35a, and the elastic deformation portion 21c can be deformed outward.

[0045] In this type of landing control panel 20, a hook portion 22c is provided at the upper end of the plate body 22b. A lower end bend portion 22d is provided at the lower end of the face plate 22. A pair of retaining portions 21b are provided at the lower end of the button case 21. Each retaining portion 21b has an elastically deformable portion 21c and a claw portion 21d. The claw portion 21d is inserted between the lower end bend portion 22d and the plate body 22b.

[0046] Then, by elastically deforming the elastically deformable portion 21c of at least one of the pair of holding portions 21b and pulling out the claw portion 21d from between the lower end bent portion 22d and the plate body 22b, the faceplate 22 becomes removable from the button case 21.

[0047] Therefore, it is possible to easily attach and detach the faceplate 22 to the button case 21, and to easily manufacture the faceplate 22 regardless of the material used to make up the faceplate 22.

[0048] Furthermore, the elastically deformable portion 21c elastically deforms in the width direction of the button case 21. This makes it possible to make the entire landing control panel 20 thinner.

[0049] Furthermore, the faceplate 22 is made of stainless steel. The hook portion 22c is formed by bending the upper end of the plate body 22b downwards. The lower end bent portion 22d is formed by bending the lower end of the plate body 22b upwards. The dimension W1 of the lower end bent portion 22d in the width direction of the faceplate 22 is smaller than the dimension W2 of the plate body 22b in the same direction.

[0050] Therefore, the entire front surface of the landing control panel 20 can be covered with a stainless steel faceplate 22, improving its aesthetic appeal. Furthermore, the faceplate 22 can be manufactured without welding or bonding, making its production more reliable and easier. In addition, the number of components can be reduced.

[0051] Furthermore, the button case 21 is configured to allow access to a pair of retaining parts 21b from the rear side. Therefore, if the landing control panel 20 is not installed on the landing wall 10, the faceplate 22 can be easily removed from the button case 21.

[0052] Furthermore, each retaining portion 21b is provided with a projection 21e. This allows the elastically deformable portion 21c to be easily elastically deformed, and the faceplate 22 to be easily removed from the button case 21.

[0053] Furthermore, a jig opening 20a is provided between the lower end of the plate body 22b and the lower end of the button case 21. Therefore, even when the landing control panel 20 is installed on the landing wall 10, the faceplate 22 can be easily removed from the button case 21.

[0054] Furthermore, the button case 21 is configured to release the holding state of the faceplate 22 by the holding part 21b only when a jig 31 or jig 35 having dimensions within the set range is inserted into the jig opening 20a.

[0055] Therefore, the removal of the faceplate 22 by ordinary elevator users is suppressed, thereby improving reliability.

[0056] Although preferred embodiments have been described in detail above, the invention is not limited to the embodiments described above, and various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.

[0057] Furthermore, the material of the faceplate 22 is not limited to stainless steel; for example, it may be a metal plate other than steel.

[0058] Furthermore, the button case 21 does not necessarily have to be configured to allow access to the pair of retaining parts 21b from the back side.

[0059] Furthermore, the projection 21e may be omitted in at least one of the holding portions 21b.

[0060] Furthermore, the jig opening 20a may be omitted.

[0061] Furthermore, the faceplate 22 may be provided with a plurality of lower end bends 22d spaced apart from each other in the width direction of the faceplate 22.

[0062] Furthermore, the number of retaining parts 21b may be one or three or more.

[0063] Furthermore, the position of the holding portion 21b is not limited to both ends in the width direction of the faceplate 22, but may also be in the center in the width direction of the faceplate 22.

[0064] Furthermore, the projection 21e may protrude outward from the elastically deformable portion 21c in the width direction of the button case 21.

[0065] Furthermore, when removing the faceplate 22 from the button case 21, the direction in which the elastic deformation portion 21c is elastically deformed may be towards the center in the width direction of the button case 21.
