SUMMARY OF THE INVENTION
PROBLEM TO BE SOLVED BY THE INVENTION
[0004] In conventional elevator operating displays such as those described above, welding
stress may be generated on the front surface of the surface plate by welding the screw-threaded
rod if a surface plate that is made of a thin metal plate is used, and in that case,
a finishing operation for relieving stress is required, increasing manufacturing costs.
If a resin surface plate is used, durability and decorative design are reduced compared
to the metal surface plate.
[0005] The present invention aims to solve the above problems and an object of the present
invention is to provide an elevator operating display that prevents welding stress
from being generated in a surface plate and that can also prevent reductions in durability
and decorative design.
MEANS FOR SOLVING THE PROBLEM
[0006] In order to achieve the above object, according to one aspect of the present invention,
there is provided an elevator operating display including: a metal surface plate;
internal-mounted equipment; and a resin fixing member that is mounted behind the surface
plate, and on which is formed an equipment fixing portion for fixing the internally-mounted
equipment.
EFFECTS OF THE INVENTION
[0007] The elevator operating display according to the present invention enables reductions
in durability and decorative design to be prevented by using the metal surface plate,
and also prevents welding stress from being generated in the surface plate by forming
the equipment fixing portion on the resin fixing member that is mounted behind the
surface plate, enabling manufacturing costs to be prevented from being increased in
order to relieve welding stress.

DESCRIPTION OF EMBODIMENTS
[0009] Preferred embodiments of the present invention will now be explained with reference
to the drawings.
Embodiment 1
[0010] Figure 1 is a front elevation that shows a landing operating panel according to Embodiment
1 of the present invention, and Figure 2 is a side elevation that shows the landing
operating panel from Figure 1. In the figures, a landing operating panel that constitutes
an elevator operating display is installed on an elevator landing. A surface plate
1 is constituted by a thin metal plate, and is worked by pressing, etc., to a predetermined
shape that is imparted with indentations and protrusions. A plurality of apertures
1a and 1b are disposed on the surface plate 1.
[0011] A display 2 is disposed in the aperture 1a. The display 2 displays information such
as present position and direction of operation, etc., of a car (not shown). A call
button 3 for calling the car is disposed in the aperture 1 b. The display 2 and the
call button 3 constitute internally-mounted equipment that is mounted internally in
the landing operating panel.
[0012] Next, a construction for mounting the call button 3 onto the surface plate 1 will
be explained. Figure 3 is a front elevation that shows part of the landing operating
panel from Figure 1, Figure 4 is a rear elevation that shows the landing operating
panel from Figure 3, Figure 5 is a cross section that is taken along line V - V in
Figure 3, Figure 6 is a cross section that is taken along line VI - VI in Figure 3,
and Figure 7 is a cross section that is taken along line VII - VII in Figure 3.
[0013] A resin fixing member 4 is mounted behind the surface plate 1. The fixing member
4 is formed by resin molding so as to have a shape that is parallel to a rear surface
of the surface plate 1. The call button 3 is fixed to the fixing member 4 by a plurality
of (in this case, two) screws 5. In other words, the call button 3 is mounted to the
surface plate 1 by means of the fixing member 4. A plurality of (in this case, two)
cylindrical button bearing projections 4a that function as equipment fixing portions
for fixing the call button 3 are formed integrally on the fixing member 4.
[0014] A base plate of the call button 3 is placed in contact with tip ends of the button
bearing projections 4a. Threaded holes 4b into which the screws 5 are screwed are
disposed centrally on the button bearing projections 4a. The screws 5 are passed through
the base plate of the call button 3 and screwed into the threaded holes 4b.
[0015] A pair of engaging hooks 4c that are bent inward to engage with the fixing member
4 are disposed on trailing end portions on two sides of the surface plate 1 to the
left and right. A state of the engaging hooks 1 c before bending is shown in Figures
4 and 5. In Figure 7, states of the engaging hook 1 c on the left before bending,
and the engaging hook 1 c on the right after bending are shown. The engaging hooks
1c are formed on the surface plate 1 in advance.
[0016] A pair of recess portions 4c that function as engaging portions with which the engaging
hooks 1c engage are disposed on the fixing member 4. The fixing member 4 is fixed
behind the surface plate 1 by inserting the tip end portions of the engaging hooks
1 c into the recess portions 4c by bending the engaging hooks 1c to restrict vertical
movement of the fixing member 4 relative to the surface plate 1. The fixing member
4 can be fixed to the surface plate 1 so as not to wobble by matching the shapes of
the recess portions 4c to the widths and the lengths of the tip end portions of the
engaging hooks 1c. In addition, as shown in Figure 7, an aperture 4d through which
the call button 3 is inserted is disposed on the fixing member 4.
[0017] In a landing operating panel of this kind, by using the metal surface plate 1, reductions
in durability and decorative design can be prevented, and well-designed shapes can
be achieved. By changing the material and the finish of the thin metal plate, variation
in the surface plate 1 can also easily be increased.
[0018] In addition, by forming the button bearing projections 4a on the resin fixing member
4 that is mounted behind the surface plate 1, welding stress is prevented from being
generated in the surface plate 1, enabling the manufacturing costs to be prevented
from being increased in order to relieve welding stress.
[0019] Because the engaging hooks 1c are disposed on the surface plate 1, and the fixing
member 4 is stopped by bending the engaging hooks 1 c, the operation of fixing the
fixing member 4 to the surface plate 1 can be further facilitated.
Because the recess portions 4c with which the engaging hooks 1 c engage are disposed
on the fixing member 4, the fixing member 4 can be fixed stably to the surface plate
1 using a simple construction.
In addition, because the button bearing projections 4a on which the threaded holes
4b are disposed are formed on the fixing member 4, the call button 3 can be fastened
to the fixing member 4 by screws using a simple configuration.
Embodiment 2
[0020] Next, Figure 8 is a rear elevation that shows an intermediate state during manufacturing
of a surface plate 1 of a landing operating panel according to Embodiment 2 of the
present invention, and Figure 9 is a cross section that is taken along line IX - IX
in Figure 8. In the landing operating panel that is shown in Figure 1, the number
of call buttons 3 is one, but two call buttons 3 are normally required on landing
operating panels that are installed on intermediate floors. In answer to that, in
Embodiment 2, an aperture 1b for a call button 3 is not disposed during formation
of a surface plate 1, and a plurality of sets of (in this case, three pairs of) engaging
hooks 1c are formed so as to be spaced apart from each other vertical.
[0021] If only one call button 3 is to be mounted, a central aperture 1b in the figure is
additionally machined, and a fixing member 4 is fixed using a pair of engaging hooks
1 c that correspond to that aperture 1b. If two call buttons 3 are to be mounted,
the two upper and lower apertures 1b in the figure are additionally machined, and
two fixing members 4 are respectively fixed by two pairs of engaging hooks 1c that
correspond to those apertures 1b. The engaging hooks 1 c that are not used may simply
be bent or cut off. The rest of the configuration is similar or identical to that
of Embodiment 1.
[0022] By adopting a configuration and manufacturing method of this kind, reductions in
part types are enabled.
Embodiment 3
[0023] Next, Figure 10 is a perspective that shows a fixing member 4 of a landing operating
panel according to Embodiment 3 of the present invention. In the figure, a plurality
of (in this case, one pair of) ribs (reinforcing projections) 4e for reinforcing a
surface plate 1 are formed integrally on a rear surface of a fixing member 4. The
ribs 4e are formed parallel to a width direction of the fixing member 4. The rest
of the configuration is similar or identical to that of Embodiment 1 (button bearing
projections 4a are omitted in Figure 10).
[0024] By using a fixing member 4 of this kind, even if a surface plate 1 that is constituted
by a thin metal plate is used, strength deficiencies in the surface plate 1 can be
overcome.
[0025] Moreover, in Embodiment 3, the ribs 4e are formed parallel to the width direction
of the fixing member 4, but the ribs 4e are not limited to this direction, and may
also be formed perpendicular to the width direction (lengthwise), for example.
The number of ribs 4e may also be one, or three or more.
In addition, a fixing member 4 only for reinforcing the surface plate 1 instead of
for mounting internally-mounted equipment may also be additionally mounted to the
surface plate 1.
[0026] Furthermore, the numbers of engaging hooks 1 c and recess portions 4c are not limited
to those of the above examples.
The engaging portions are not limited to the recess portions 4c, and may also be projecting
portions with which the engaging hooks 1 c engage, for example.
In addition, in the above examples, cases have been explained in which the internally-mounted
part that is mounted to the surface plate 1 is the call button 3, but the present
invention can be applied to various mounting constructions in which internally-mounted
equipment such as the display 2 or a screw seat (not shown) for fixing the surface
plate 1 to a wall, etc., is mounted to the surface plate 1, for example. The shape
of the fixing member 4 can also be modified to match the shape or purpose of the internally-mounted
equipment that is mounted.
Furthermore, the present invention can also be applied to elevator operating displays
other than landing operating panels, such as landing displays, car operating panels,
and onboard displays, for example.
