Description

  The present invention relates to an operating device used as, for example, a remote operating device for a hot water supply device, and more particularly to an operating device of a type in which a rotary lid is attached to an operating device main body.

  As an example of a conventional operation device for a hot water supply device, for example, as described in Patent Document 1, there is one in which a lid is rotatably attached to an operation device main body provided with an operation switch. When this lid is closed, it is possible to cover a part of the front surface of the operating device main body. By opening this lid, for example, an operation switch that is not frequently used is normally exposed outside. The operation switch can be appropriately operated. In this type of operating device, as an angle regulating means when the lid is opened, a part of the lid collides with the operating device main body when the lid is opened widely, and the lid body has a larger angle than that. Often means are used to prevent the from opening.

  However, the prior art has the following problems.

  That is, conventionally, when the lid is opened widely and a part of the lid collides with the operating device main body, a rebounding force is applied to the lid from the operating device main body, and the lid bounces. In some cases, the phenomenon occurred. If such a bounce occurs, the lid cannot be immediately stabilized at a predetermined angle. In addition, there is a problem that a collision sound between the lid and the operating device main body is generated. In particular, such a phenomenon becomes more prominent when the user opens the lid vigorously. In addition, when the lid is set so as to hang downward when the lid is fully opened, the lid will cause a bounce as described above for a relatively long time due to the above-mentioned bounce. Will not give a positive impression to the user.

JP-A-6-229624

  The present invention has been conceived under the circumstances as described above, and when the rotary lid is opened, the lid bounces due to a collision with the operating device main body. It is an object of the present invention to provide an operating device that can appropriately prevent problems with a simple structure.

  In order to solve the above problems, the present invention takes the following technical means.

  An operating device provided by the present invention includes an operating device main body provided with an operating switch, and a closed cover that is rotatably provided relative to the operating device main body and covers at least a part of the operating device main body. A lid that is changeable from a state to an open state that does not cover the part, and a lid stopper provided on one of the manipulation device main body and the lid And a convex portion for the lid stopper provided on the other of the operating device main body and the lid body and when the lid body is rotated in one direction from the closed state to be opened. An entry portion forming region that forms an entry portion for a projection that can enter the projection, and the projection for the lid stopper and the entry portion formation region include the entry of the projection to the entry portion. When entering the part, the lid body Serial one-direction with a frictional force to prevent bouncing in the opposite direction is characterized by being configured to contact each other.

  According to such a configuration, when the lid is opened, the convex portion for the lid stopper enters the entry portion, and the entry portion formation region and the lid contact with each other with frictional force. Bounding in the direction opposite to the direction in which the lid opens is appropriately prevented. Therefore, the behavior of the lid can be stabilized so as not to give a bad impression to the user. Moreover, it is possible to suppress the occurrence of a collision sound between the lid and the operating device main body. In the present invention, as a means for preventing the lid from bouncing, a combined structure of the convex portion for the lid stopper and the entry portion forming region is used, but the convex portion and the entry portion for the lid stopper are used. Each of the formation regions can be formed in a simple shape, for example, integrally with the operating device main body or the lid, and can be easily provided without using a separate member from the lid. Can do. Therefore, it is possible to appropriately avoid the problem that the manufacturing cost of the operating device is significantly increased.

  In a preferred embodiment of the present invention, at least one of the convex part for the lid stopper and the entry part forming region is at least one of the convex part and the entry part when the convex part enters the entry part. The width or the diameter of the projection changes and the elastic deformation can occur so as to generate a resilient force that presses the convex portion and the entry portion forming region against each other.

  According to such a configuration, the convex portion and the entry portion forming region are brought into pressure contact with each other using the elastic force generated by the elastic deformation of at least one of the convex portion for the lid stopper and the entry portion forming region. Therefore, it is possible to more reliably prevent bouncing when the lid is opened. In addition, when the convex portion enters the entry portion, at least one of the widths or diameters changes, and the impact when the convex portion and the entry portion formation region come into contact can be reduced. Wear due to contact between the portion and the entry portion forming region can also be reduced.

  In a preferred embodiment of the present invention, the convex portion for the lid stopper is integrally molded with a resin component of either the operating device main body or the lid. As a means for allowing the convex portion to be elastically deformed, the convex portion has at least one slit that divides the entire length region or a partial region in the height direction into a plurality of regions in the width direction or the diameter direction of the convex portion. is doing.

  According to such a configuration, since the convex portion for the lid stopper can be integrally molded with the constituent member of either the operating device main body or the lid, its manufacture is facilitated. In addition, as means for enabling the convex portion to be elastically deformed, means for providing a slit in the convex portion is employed, and therefore it is not necessary to form the convex portion using an elastic material. The slit can be formed at the same time as the projection is formed.

  In a preferred embodiment of the present invention, the entry portion is configured as a hole that can be fitted with the protrusion for the lid stopper, and the protrusion is formed on the inner peripheral surface of the hole. The outer surface can be pressed.

  According to such a configuration, the inner peripheral surface of the hole portion as the entry portion and the outer surface of the convex portion for the lid stopper can be accurately brought into pressure contact with each other in a relatively wide area, and the bounce prevention of the lid body is ensured. This is preferable for the purpose.

  In a preferred embodiment of the present invention, the entry portion forming region includes a pair of protruding pieces arranged at intervals, and a gap formed between the pair of protruding pieces is the entry portion. The pair of projecting pieces can be elastically deformed in a direction in which they are aligned with each other, whereby the width of the entry portion can be changed.

  According to such a configuration, the structure that allows the entry portion forming region to be elastically changed so that the width of the entry portion can be changed is realized by a simple structure using a pair of projecting pieces, thereby facilitating manufacture. Can be achieved.

  In a preferred embodiment of the present invention, the lid body covers at least a part of the front surface portion of the operating device main body portion in the closed state, and a part of the lid body is a front surface portion of the operating device main body portion. The operating device main body is provided so as to be a protruding portion that protrudes, and the convex portion for the lid stopper is located behind the protruding portion of the lid when the lid is closed. The entry portion forming region is provided on the lid body so as to be positioned on the back side of the lid body when the lid body is in a closed state.

  According to such a configuration, in the closed state of the lid, it is possible to prevent the convex portion for the lid stopper and the entry portion forming region from being seen from the front of the lid and the operating device main body. Therefore, it is preferable for improving the appearance of the operating device.

  As shown in FIGS. 1 to 3, the operation device A <b> 1 includes an operation device main body 1, a cover 2, a protrusion 3 for a cover stopper, and a hole corresponding to the protrusion 3. The entrance portion forming region 4 in which the entrance portion 40 is formed is provided.

  The operating device body 1 has a configuration in which a circuit board (not shown) constituting a predetermined data processing circuit is accommodated in a housing 10 made of resin such as ABS resin. A data display unit 11 and a plurality of operation switches 12 a and 12 b are provided on the front surface of the housing 10.

  The lid 2 is a substantially rectangular plate formed separately from the operating device main body 1 and is made of the same resin as the housing 10. Although not shown in the drawings, the lid 2 can be configured to be provided with operation switches in the same manner as the lid described in Patent Document 1. The lid 2 is rotatably connected to the operating device main body 1, and is in a closed state (state shown in FIG. 1) that covers an area of the front surface of the operating device main body 1 where the operation switch 12 b is provided. It is possible to switch to the open state (the state of FIG. 2) that does not cover the region. As a means for rotatably connecting the lid 2 to the operating device main body 1, as shown in FIG. 3, a pair of bosses 29 a and 29 b formed in the vicinity of the side edge 20 of the lid 2 Means for providing the hole 28 and providing a pair of protrusions 18 on both end surfaces of the rib 19 provided on the lower surface 13 of the operating device main body 1 and fitting the protrusions 18 and the holes 28 together. It has been adopted. As a means for stabilizing the closed state of the lid body 2 shown in FIG. 1, for example, a means for attaching a magnet or an iron plate (not shown) to the lid body 2 and the operation device main body 1 and adsorbing them by magnetic force is adopted. be able to.

  The entry portion 40 is for fitting the convex portion 3 for the lid stopper, and as described above, the entry portion 40 is formed as a hole in the present embodiment, and the standing wall 21 provided on the lid 2. Is provided. The upright wall 21 is a portion protruding in the same direction as the boss portions 29 a and 29 b from the side edge portion 20 of the lid body 2, and extends to an appropriate length along the side edge portion 20. A part or all of the standing wall 21 is the entry portion forming region 4. In the present embodiment, the mechanical strength is increased by connecting the standing wall 21 and the boss portion 29a, but it is needless to say that they may be separated. A notch portion 14 for avoiding interference between the operating device main body 1 and the standing wall 21 of the lid 2 is provided at the lower portion of the operating device main body 1, as shown by a virtual line in FIG. 2. When the lid 2 is set in the fully open state in which the lid 2 is suspended downward, the upright wall 21 enters the notch 14 and the lid 2 can be arranged directly below the operating device main body 1. Has been.

  The convex portion 3 for the lid stopper is provided so as to protrude downward from the lower surface portion 13 of the operating device main body 1. The lid body 2 has a protruding portion 25 that protrudes downward by an appropriate width S1 from the front portion of the operating device main body 1 in the closed state (see FIG. 4A). It is provided so as to be hidden behind the protruding portion 25. The convex portion 3 is integrally molded with the housing 10. An outer surface near the lower end of the convex portion 3 is a substantially spherical inclined surface 30. As shown well in FIG. 4B, the convex portion 3 is formed with a slit 31 extending in the height direction. The side region is divided into two regions 32 a and 32 b through the slit 31. Thereby, the convex part 3 can be elastically deformed in the width direction. On the other hand, as for the approach part 40, the whole or one part of the internal peripheral surface 40a is made into the inclined surface. As shown in FIG. 4, when the lid body 2 is in the closed state, the entry portion 40 is in a positional relationship separated from the convex portion 3. On the other hand, as shown in FIG. 5, when the lid body 2 is rotated in the direction of the arrow N <b> 1 around the protrusion 18 to be in the open state, the entry portion 40 is provided so as to be engaged with the convex portion 3. ing. At the time of this fitting, the inner peripheral surface 40a of the entry portion 40 comes into contact with the inclined surface 30 of the convex portion 3, presses the inclined surface 30, and the width of the convex portion 3 is reduced in the direction of the arrow N3. It is configured to be elastically deformed.

  Next, the operation of the operation device A1 will be described.

  First, in the closed state of the lid body 2 shown in FIG. 1, the user pulls the upper side region of the lid body 2 toward the near side to open the lid body 2 and rotate it in the direction of arrow N1 in FIG. be able to. When the lid 2 is rotated to the state indicated by the phantom line in FIG. 2, as described with reference to FIG. 5, the convex portion 3 for the lid stopper and the entry portion 40 are fitted to each other. The inclined surface 30 as the outer surface portion and the inner peripheral surface (inclined surface) 40 a of the entry portion 40 are in contact with each other, and the frictional force due to this contact acts as a force for maintaining the fitting state between the convex portion 3 and the entry portion 40. In particular, in this embodiment, the inclined surface 30 of the convex portion 3 is pressed by the inner peripheral surface 40a of the entry portion 40, and the convex portion 3 is elastically deformed so that its width is reduced in the direction of the arrow N3. Due to the elastic force (elastic restoring force) of the convex portion 3, the inclined surface 30 of the convex portion 3 and the inner peripheral surface 40a of the entry portion 40 are pressed against each other with a stronger force. Therefore, the lid body 2 does not bounce in the direction opposite to the arrow N1 as soon as the inner peripheral surface 40a of the entry portion 40 contacts the projection portion 3, and the projection portion 3 comes off the entry portion 40 and is covered. The phenomenon that the body 2 is unstablely shaken can be appropriately avoided. Moreover, in the smooth fitting operation | movement of the approach part 40 and the convex part 3 which were mentioned above, it can also be made not to produce a loud collision sound.

  Further, in the present embodiment, as described above, the convex portion 3 is elastically deformed so that the width of the convex portion 3 is reduced when the convex portion 3 enters the entrance portion 40. The phenomenon that the surface 40a wears due to these contacts can be made difficult to occur. If the convex portion 3 or the inner peripheral surface 40a of the entry portion 40 is repeatedly worn and greatly deformed (scraped), it becomes difficult to accurately bring these portions into close contact with each other. However, according to the present embodiment, such a possibility can be appropriately eliminated, and the bounce prevention function of the lid body 2 can be maintained for a long period of time.

  In the closed state of the lid 2 shown in FIGS. 1 and 4, the convex portion 3 is hidden by the lid 2. In addition, the entry portion formation region 4 is also located on the back side of the lid 2 and hidden. Therefore, in the normal state in which the lid 2 is closed, the convex portion 3 and the entry portion formation region 4 are not visible from the front surface of the operating device A1, and the appearance of the operating device A1 is improved. it can. On the other hand, in the open state of the lid body 2 shown in FIG. 5A, the entry portion 40 as a hole provided in the standing wall 21 is hidden directly under the operating device A1, and the convex portion 3 is also in the entry portion 40. It becomes a hidden state by being inserted. Therefore, even when the lid 2 is in the open state, it is possible to prevent the entry portion formation region 4 and the convex portion 3 from appearing unsightly from the front surface of the operating device A1 or the like (note that other embodiments will be described later). In the state shown in FIG. 8, there is a possibility that the convex portion 3 and the entry portion forming area 4A can be seen from the front of the controller device A2. The convex portion 3 is resin-molded integrally with the housing 10 of the operating device main body 1, and the entry portion formation region 4 is resin-molded integrally with the lid 2. For this reason, formation of these convex part 3 and the entrance part formation area | region 4 is also easy, and it can suppress the raise of the manufacturing cost of operating device A1.

  6 to 10 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment. Further, in these drawings, the configuration of the portion that rotatably supports the lid body 2 is omitted.

  In the operating device A2 illustrated in FIG. 6, the entry portion forming region 4A is configured to include a pair of projecting pieces 26 provided side by side along the side edge portion 20 of the lid body 2. The entry portion 40A is a gap formed between the pair of protruding pieces 26. As shown in FIG. 7, the pair of projecting pieces 26 are arranged so as not to interfere with the convex portion 3 for the lid stopper when the lid 2 is in the closed state. Is rotated in the direction of arrow N1 to be in an open state, so that the convex portion 3 is provided to enter the entry portion 40A. At that time, as a result of the inner surfaces of the pair of projecting pieces 26 coming into contact with the inclined surface 30 of the convex portion 3 and pressing the inclined surface 30, the convex portion 3 is elastically deformed so that its width is reduced in the direction of the arrow N3. To do. In addition, the pair of projecting pieces 26 are also elastically deformed in the direction of the arrow N4 by contact with the convex portion 3.

  According to the present embodiment, when the lid 2 is opened, the lid stopper convex portion 3 and the pair of projecting pieces 26 come into contact with each other, and a large frictional force is generated between them. The state in which the part 3 enters the entry part 40A is maintained. Therefore, similarly to the above embodiment, the lid 2 is appropriately prevented from bouncing. Further, when the convex portion 3 enters the entry portion 40A, not only the convex portion 3 is elastically deformed, but also the pair of projecting pieces 26 are also elastically deformed, so that the convex portion 3 and the pair of projecting pieces 26 The pressure contact force can be increased. This is preferable for more reliably preventing the lid body 2 from bouncing.

  In the embodiment shown in FIG. 9, the convex portion 3A for the lid stopper is formed in a truncated cone or a conical shape, and the outer peripheral surface of the convex portion 3A is an aspherical inclined surface 30A. In the present invention, when the outer surface of the convex portion for the lid stopper is an inclined surface, the inclined surface can have a shape other than a spherical shape or a substantially spherical shape. In the present embodiment, the convex portion 3A is not provided with means corresponding to the slit 31 shown in the previous embodiment. On the other hand, the entry portion 40B of the entry portion forming region 4B provided in the lid body 2 is formed as a tapered hole, and when the lid body 2 rotates in the direction of the arrow N1 and the convex portion 3A is fitted, A part of the inclined surface 30A of the convex part 3A and a part of the inclined inner peripheral surface 40b of the entry part 40B are configured to be in close contact with each other at a position indicated by reference numeral n1. In the present embodiment, when the convex portion 3A and the entry portion 40B are fitted, the convex portion 3A and the entry portion forming region 4B are not greatly elastically deformed, but a part of the inclined surface 30A of the convex portion 3A. And a part of the inner peripheral surface 40b having an inclination corresponding to this can be brought into close contact with each other to generate a strong frictional force. Thus, it is possible to prevent the convex portion 3A from coming off from the entry portion 40B and to prevent the lid body 2 from bouncing in the direction opposite to the arrow N1.

  In the embodiment shown in FIG. 10, the protrusion 3A for the lid stopper is the same as that shown in FIG. 9, whereas the entry portion 40C of the entry portion forming region 4C provided in the lid 2 is In addition, it is formed as a hole having an inner peripheral edge 40c having a shape and size corresponding to the inclined surface 30A of the convex portion 3. When the lid body 2 rotates in the direction of the arrow N1 and the convex portion 3A is fitted into the entry portion 40C, the inner peripheral edge 40c bites the inclined surface 30A of the convex portion 3A at the portion indicated by reference numeral n2. It can be pressed. Even with this configuration, it is possible to prevent the lid 2 from bouncing by preventing the convex portion 3A from coming off the entry portion 40C. However, in the embodiment shown in FIGS. 9 and 10, there is a risk that the convex portions 3A and the inner surface portions of the entry portions 40B and 40C that are in contact with each other are likely to be worn. Therefore, from the viewpoint of eliminating such a concern, it is preferable that the convex portion and the entry portion forming region can be elastically deformed as in the embodiment described with reference to FIGS.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the operating device according to the present invention can be modified in various ways.

  The convex portion for the lid stopper can be formed in a substantially spherical shape, a truncated cone shape, or a shape other than the cone shape (for example, a pyramid shape). In the case where a means is used to make the convex portion elastically deformable in the width direction or the diameter direction by providing a slit in the convex portion for the lid stopper, a plurality of slits may be provided. Further, for example, by providing a cross-shaped slit, the convex portion can be separated into four regions to be elastically deformable. In the present invention, as means for enabling the convex portion to be elastically deformed, means for forming the convex portion itself with synthetic rubber or other elastic members may be employed.

  The entry portion referred to in the present invention may be a hole or a gap as long as at least a part of the projection for the lid stopper enters when the lid is opened. It does not matter whether or not. The hole may be cutout or non-cutout. Moreover, it can replace with a through-hole and can also be set as a non-through-hole (recessed part).

  The position of the convex portion for the lid stopper and the entry portion forming region is not limited to the lower surface portion of the operating device main body portion or one side edge portion of the lid body, and may be provided in other portions. Contrary to the above-described embodiment, the convex portion may be provided on the lid and the entry portion forming area may be provided on the operating device main body. The lid body is not limited to a system that is opened by rotating the front side lower part of the operation device main body, and for example, a lateral opening system (a system in which the lid body rotates in the horizontal direction) can be used. Needless to say, the arrangement of the convex portions and the entry portion forming regions should be changed accordingly. The lid does not have to cover the operation switch provided in the operating device main body, and may cover a portion other than the operation switch (for example, the display unit).

  The operation device according to the present invention is for remote operation of various devices and devices (for example, water treatment devices such as cogeneration systems, heat pumps, air conditioners, water softeners, etc.) as well as for hot water supply devices. It can comprise as an operating device other than.
