Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slide device having a base material and a slide member that moves relative to the base material, and more particularly, to a slide device with improved operational feeling when the slide member moves relative to the base material.
[0002]
[Prior art]
The slide device performs various mechanical or electrical operations using relative movement of the slide member with respect to the base material. In such a slide device, the operational feeling in the slide operation is improved by adjusting the operation load when the slide member is moved relative to the base material (hereinafter referred to as a slide). In order to adjust the operation load, generally, a spacer is provided on one of the base member and the slide member, and the other member is pressed by a biasing force of the spacer toward the other member. The spacer of the slide device is generally formed of a metal material such as spring steel, SUS, phosphor bronze plate, or a polymer material, and imparted with an urging force (for example, Patent Documents 1 to 3). ).
[0003]
Patent Document 1 discloses a register that adjusts a wind direction by operating rotation of a blade. The slide device disclosed herein adjusts the wind direction by rotating the blade by sliding the operation knob (slide member in this specification) with respect to the blade (base material in this specification). A spring is used as a spacer for adjusting the load. Therefore, a biasing force is applied to the spacer by the elasticity of the spring.
[0004]
Patent Document 2 discloses a slide switch in which a wire spring is used as a spacer, and a biasing force is applied to the spacer by the elasticity of the wire spring.
[0005]
Patent Document 3 discloses a register in which an elastic synthetic resin is used as a spacer, and a biasing force is applied to the spacer by the elasticity of the elastic synthetic resin.
[0006]
Here, for example, when a metal spring is used as the spacer, an operation load in the slide operation can be obtained by the urging force resulting from the elasticity of the spring, but there is a problem that the operation feeling during the slide operation is inferior. That is, the spacer is a portion that is disposed on one member and presses the other member and is a portion that is in sliding contact with the other member. There has been a problem that the sliding contact with the other member is not performed smoothly. In addition, the metal spacer causes an operational feeling such that it slides in contact with the other member at the time of sliding, so that a smooth operational feeling cannot be obtained and it is difficult to finely adjust the sliding distance. There was also a problem.
[0007]
In addition, when a spacer made of a polymer material is used, an operation load at the time of sliding is obtained by the urging force caused by the elasticity of the polymer material, and the operation at the time of sliding is obtained by the friction characteristics of the polymer material. A feeling improves. Here, in this specification, the friction characteristic refers to a characteristic that improves the operational feeling due to friction, and refers to a characteristic that can provide smooth sliding contact and appropriate frictional resistance during a sliding operation. When a spacer made of a polymer material is used as the spacer, the spacer made of the polymer material smoothly slides against the other member during the sliding operation, and a good operation feeling can be obtained. Fine adjustment of the slide distance can be easily performed by an appropriate frictional resistance of the.
[0008]
However, when the spacer is formed of a polymer material, it is necessary to provide a large elasticity of the spacer made of the polymer material in order to obtain a sufficient operation load. The elasticity of the spacer can be appropriately set depending on the thickness of the polymer material in the elastic direction, but the polymer material may be thermally deformed under high temperature conditions. The wall thickness may be insufficient to obtain sufficient operational load. Therefore, after the slide device is exposed to a high temperature condition, for example, when the slide device is installed in the passenger compartment, there is a problem that the operation load is greatly reduced when the temperature of the passenger compartment increases in the summer. .

[0012]
By configuring the spacer from the urging member and the sliding contact member laminated on the surface of the urging member, the urging force is secured by the urging member and the operation feeling at the time of the slide operation is secured by the sliding contact member. Thus, it is possible to obtain both a good urging force and a good feeling of operation.
[0013]
In the sliding device of the present invention, the sliding contact member is preferably made of a rubber material.
The rubber material is preferably silicon rubber .
[0016]
DETAILED DESCRIPTION OF THE INVENTION
The slide device of the present invention can be applied to various devices as long as various operations are performed by sliding. For example, it can be suitably used for a register that adjusts the wind direction by operating the rotation of the blade as described above, a slide switch, or the like.
[0017]
The slide device of the present invention is a slide device including a base material and a slide member held on the base material so as to be relatively movable. A base material formed of a resin material can be used. The base material is provided with a slide surface on which the slide member slides, and the slide member slides on the slide surface at a position where it comes into contact with the base material. Moreover, since the slide member slides with respect to the base material, it has a certain movement range at least on the slide surface. This moving range can be regulated by the base material, or can be regulated by other regulating members.
[0018]
In the slide device of the present invention, the slide of the slide member is directly or indirectly transmitted to the operating member, and mechanical operation and electrical operation of the operating member are performed. When the slide is directly transmitted to the operating member, an operating member is provided at a predetermined position in the moving range of the slide member, and a part of the slide member is brought into direct contact with the operating member during the slide operation to operate the slide. It can be set as the structure which operates an operation member by transmitting to. Further, when the slide is indirectly transmitted to the operating member, a transmission means driven by the slide of the slide member is connected to one or both of the slide member and the base member, and the transmission means to which the slide is transmitted is driven. Further, the operation member can be operated by being transmitted to the operation member. This transmission can be performed by converting a slide that is a physical motion into another physical motion such as a rotational motion, or can be converted into an electrical signal or the like.
[0019]
In the present invention, the slide member is provided with a spacer. The spacer is formed so as to be urged to the base material , and is supported by the slide member to press the base material . By this pressing, the operation load of the slide member with respect to the base material during the slide operation is ensured.
[0020]
The urging member can be formed in a known shape that exhibits elasticity by a known metal material such as spring steel, SUS, phosphor bronze plate, or a resin material. Further, at least a part of the urging member is supported by a part of the slide member , and the other part protrudes between the base member and the slide member. Therefore, urging | biasing is performed in the protrusion direction, ie, the other member direction, by this protruded part.
[0021]
In the slide device of the present invention, a sliding contact member is laminated on the surface of the biasing member, and the sliding contact member is pressed against the surface of the base material by the biasing force of the biasing member. Further, the sliding member slides on the sliding surface of the base material together with the pressing, so that the sliding contact member comes into sliding contact with the surface of the base material . In the slide device of the present invention, the operation feeling during the slide operation is improved by pressing the sliding contact member against the base material .
[0022]
Sliding member may be formed with known materials to improve the operation feeling at the time of sliding, from the viewpoint of operability improvement, it is formed of a polymeric material. Examples of the polymer material include resin materials such as silicon resin, fluorine resin, PVC resin, SEBS resin, and TPO (olefin-based thermoplastic elastomer), and rubber materials such as silicon rubber and fluorine rubber . By forming the sliding member with these materials, for example, the sliding operation can be made smoother and more appropriate than the case where the spacer is constituted by only a metal biasing member, and at the time of the sliding operation It is possible to improve the feeling of operation and to easily perform fine adjustment of the slide operation.
[0023]
Lamination of the sliding member with respect to the urging member can be performed by a known method. For example, the sliding member can be formed on the surface of the biasing member by known means such as spraying, coating, dipping, potting, or the sliding member can be formed on the surface of the biasing member by insert molding. Furthermore, it is also possible to stack the sliding contact member on the surface of the biasing member by integrating the biasing member formed separately and the sliding contact member by known means such as adhesion or engagement. . Further, the sliding member can be laminated on the entire surface of the urging member, or can be laminated only on a portion of the urging member that is in sliding contact with the surface of the base member .
[0024]
In the slide device of the present invention, by configuring the spacer with the biasing member and the sliding contact member, the biasing force can be secured by the biasing member, and the operational feeling can be secured by the sliding contact member. That is, in the slide device having the conventional configuration, as described above, when the entire spacer is made of a metal material, the feeling of operation is inferior, and when the entire spacer is made of a polymer material, the temperature is high. There was a problem that the operation load was reduced by being exposed to the conditions. However, according to the configuration of the present invention, the spacer is composed of the urging member and the sliding contact member, and the sliding contact member is in sliding contact with the surface of the base material . The Rukoto. Since the urging force by the urging member does not change even under various temperature conditions, the operation load on the base member of the slide member is constant regardless of the temperature condition. For this reason, it is possible to obtain a good operation load and a good operation feeling regardless of temperature conditions. Here, in order to further reduce the change due to the temperature condition of the urging force by the urging member, it is more preferable that the urging member is made of metal.
[0025]
In the slide device of the present invention, it is preferable that the sliding contact member is formed to be thin. Here, when the sliding contact member itself has elasticity, the biasing force in the base material direction of the spacer is the sum of the biasing force by the biasing member and the elasticity of the sliding contact member. Therefore, depending on the material of the slidable contact member, when the slidable contact member is formed thick, the elastic force of the slidable contact member itself is greatly involved in the biasing force of the spacer in the base material direction. In this case, when the sliding contact member is deformed under a high temperature condition, the elasticity of the sliding contact member itself may decrease, and the operation load may decrease. Therefore, the thickness of the slidable contact member is reduced, the portion of the urging force of the spacer is reduced by the elasticity of the slidable contact member itself, and the portion borne by the urging force of the urging member is set to be larger. It becomes possible to reduce the influence of the temperature condition on the biasing force. In addition, since the operational feeling of the sliding operation is not so much related to the thickness of the sliding contact member, in the sliding device of the present invention, the sliding contact member itself is thermally deformed by being exposed to a high temperature condition. Even so, a good operational feeling is maintained.
[0026]
In the sliding device of the present invention, the thickness of the sliding contact member is desirably 2.0 mm or less. As described above, it is preferable that the thickness of the sliding member is thin. If the thickness of the sliding member exceeds 2.0 mm, the ratio of the elasticity of the sliding member in the biasing force of the spacer increases. In some cases, sufficient operation load may not be obtained during thermal deformation. Further, the thickness of the sliding contact member is preferably as thin as possible, and may be a thickness that does not cause breakage due to the slide. Considering the possibility of breakage due to sliding of the sliding contact member, the wall thickness is more preferably about 0.1 mm or more.
