Description

  The present invention relates to a device that can be adsorbed and fixed to a mounting surface such as a wall surface.

  Conventionally, in order to attach various devices and instruments to a mounting surface such as a wall surface, suction cups made of an elastic material such as an elastomer have been widely used (for example, Patent Document 1). A hook or the like for hooking is attached.

  There is also known an electronic device in which a suction disk is attached to the device main body, and the device main body can be fixed to the surface of a desk or the like by the suction disk (for example, Patent Document 2).

  However, when an elastic material having a relatively large elastic coefficient, such as an elastomer, is used as the material of the suction plate, such an elastic material is difficult to elastically deform in response to the action of a tensile force. When a large tensile force is applied to the surface, the suction disk may easily come off from the mounting surface.

Therefore, it is conceivable to use a material having a small elastic coefficient such as a synthetic rubber (neoprene: trade name) mainly composed of chloroprene as the material of the suction disk.
Synthetic rubber mainly composed of chloroprene has a smaller elastic coefficient than elastic materials such as elastomers and is highly stretchable. Even when a large tensile force is applied in the vertical direction, the suction surface of the suction cup is elastically deformed while maintaining the negative pressure in the internal space in a state where the suction surface is in close contact with the mounting surface. Excellent adsorption performance is demonstrated.

However, in the suction disk made of synthetic rubber mainly composed of chloroprene, when an external force parallel to the mounting surface is applied, the suction disk is greatly elastically deformed in the lateral direction, thereby destroying the negative pressure state, The suction plate can be easily detached from the mounting surface.
Therefore, the suction disk made of synthetic rubber mainly composed of chloroprene is limited to suction fixation where a large external force does not act on a horizontal mounting surface such as a desk surface, and there is a problem of low versatility in terms of application. .

  SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of adsorbing and fixing, which can obtain excellent adsorbing performance not only in the direction perpendicular to the mounting surface but also in the parallel direction.

  In the suction-fixable device according to the present invention, a suction member (5) having a suction surface (50) exposed to the outside of the device main body (2) with respect to the device main body (2), and the suction member (5) An elastic member (6) having a pressure-bonding surface (60) exposed in the same direction as the suction surface (50) of the device and exposed to the outside of the device body (2) is attached to the suction surface (50) of the suction member (5). And the pressure-bonding surface (60) of the elastic member (6) can be brought into close contact with the attachment surface (90) of the adsorption partner at the same time, and the elastic member (6) is more elastic than the material of the adsorption member (5). It is made of an elastic material having a large coefficient.

  According to the device capable of being fixed by suction, the device main body (2) with the suction surface (50) of the suction member (5) and the crimping surface (60) of the elastic member (6) opposed to the mounting surface (90). Is pressed against the mounting surface (90), the adsorbing member (5) and the elastic member (6) are elastically deformed, and the adsorbing member (5) is elastically deformed so that the adsorbing surface (50) becomes the mounting surface (90). The elastic member (6) is pressed against the mounting surface (90) by the elastic deformation of the elastic member (6).

Here, when a tensile force perpendicular to the mounting surface (90) is applied to the device body (2), the suction member (5) exhibits sufficient suction performance, so that the device body (2) is mounted on the mounting surface ( 90) It is unlikely that the elastic member (6) will have a larger elastic coefficient than the adsorbing member (5) when an external force in the direction along the mounting surface (90) acts on the device body (2). Therefore, only slight elastic deformation occurs. Accordingly, the elastic deformation in the direction along the attachment surface (90) is also slight for the adsorption member (5), and the adsorption surface (50) of the adsorption member (5) is maintained in the state of being adsorbed by the attachment surface (90). Therefore, the possibility that the device body (2) is detached from the mounting surface (90) is low.

In a specific embodiment, the adsorbing member (5) is made of synthetic rubber mainly composed of chloroprene, and the elastic member (6) is made of elastomer.
According to the specific embodiment, the synthetic rubber mainly composed of chloroprene has a smaller elastic coefficient than that of the elastomer and exhibits a large elasticity, so that a large tensile force in the vertical direction acts on the device body (2). Even in this case, the adsorbing member (5) exhibits high adsorbing performance. In addition, since an elastomer has a larger elastic coefficient than a synthetic rubber mainly composed of chloroprene and is not easily elastically deformed, even when a large external force in the direction along the mounting surface (90) acts on the device body (2), The elastic member (6) is only slightly elastically deformed and sufficiently suppresses elastic deformation in the direction along the attachment surface (90) of the adsorbing member (5).

The material of the adsorbing member (5) is not limited to the synthetic rubber mainly composed of chloroprene, and various elastic materials known as the material of the adsorbing member (5) can be used.
The material of the elastic member (6) is not limited to the elastomer, and has a larger elastic coefficient than the material of the adsorbing member (5) and is more elastic than the material of the device body (2) to which the elastic member (6) is attached. Various elastic materials having a small coefficient can be used.

In a specific aspect, the adsorbing member (5) has a body part (51) connected to the device body (2) and a skirt part (52) extending from the body part (51) to the hem. The elastic member (6) is formed in a ring shape surrounding the adsorbing member (5).
According to the specific aspect, since the elastic member (6) surrounds the adsorption member (5), it is assumed that external forces in various directions along the mounting surface (90) act on the device body (2). In addition, the elastic member (6) effectively suppresses elastic deformation of the adsorbing member (5). Further, since the adsorbing member (5) is surrounded by the elastic member (6), the adhesion of dust is prevented, so that the adsorbing performance of the adsorbing member (5) is maintained for a long time.

In a more specific aspect, the device main body (2) has a suction release piece (7) for pressing the suction member (5) and elastically deforming it in a direction along the attachment surface (90) of the suction partner. It is attached.
According to the specific embodiment, the suction member (5) is pressed by the suction release piece (7) and elastically deformed in a direction along the attachment surface (90) of the suction partner, thereby causing the negative pressure of the suction member (5). The state can be easily released and the device body (2) can be removed from the mounting surface (90) with a single touch.

  According to the apparatus capable of adsorbing and fixing according to the present invention, excellent adsorbing performance can be obtained not only in the direction perpendicular to the mounting surface but also in the direction of an external force in a parallel direction. Therefore, regardless of the orientation of the mounting surface and the direction in which the external force acts, it is possible to realize suction fixing with high versatility.

Hereinafter, embodiments of the present invention applied to a digital camera will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, a digital camera (1) according to an embodiment of the present invention has a suction member (5) on the back surface of a camera body (2) having a photographing lens (3) and a shutter button (4). ) And a ring-shaped elastic member (6) surrounding the adsorption member (5). Further, a suction release piece (7) is attached to the camera body (2).

  Inside the camera body (2), as shown in FIG. 7, internal components (20) such as an optical system, a mechanism system, and an electronic circuit system are provided.

The adsorbing member (5) is made of synthetic rubber (neoprene: trade name) mainly composed of chloroprene, and is fastened to the camera body (2) by a fixing screw (8) as shown in FIG. A power trunk part (51), a skirt part (52) that expands from the trunk part (51) toward the rear, and a ring-shaped rib part protruding forward from the hem part (52) (53).
As shown in FIG. 7, a ring-shaped suction surface (50) is formed on the skirt (52) of the suction member (5) toward the rear of the camera body (2). Exposed to

The elastic member (6) is made of an elastomer material, and as shown in FIG. 4, the elastic member (6) is ring-shaped along the surface of the outer peripheral rib (22) projecting from the back of the camera body (2). It extends and is fixed to the surface of the outer peripheral rib (22).
As shown in FIG. 7, a ring-shaped crimping surface (60) is formed on the surface of the elastic member (6) toward the rear of the camera body (2), and is exposed to the outside of the camera body (2). Yes.

  The suction surface (50) of the suction member (5) and the pressure-bonding surface (60) of the elastic member (6) face the same direction, and form a slight step as needed.

Further, a through hole (21) is formed in the side wall of the camera body (2) as shown in FIGS. 3 and 4, and the suction release piece (7) shown in FIG. 4 slides in the through hole (21). It penetrates movably.
The suction release piece (7) has a long hole (71) that is long on the left and right along the back of the camera body (2), and the suction release piece (7) passes through the through hole (21). As shown in FIG. 7, the guide screw (81) passes through the long hole (71) of the suction release piece (7), and the tip thereof is screwed into the camera body (2).

  As shown in FIG. 7, the tip of the suction release piece (7) faces the rib portion (53) of the suction member (5), and the suction release piece (7) is in the longitudinal direction of the long hole (71). By pushing in, the tip of the suction release piece (7) comes into contact with the rib portion (53) of the suction member (5).

As shown in FIG. 5, the digital camera (1) can be used by being fixed to a mounting surface (90) formed on the front surface of an information processing device (9) having a communication function, for example.
As shown in FIG. 6, the information processing device (9) has a screen (91) and operation keys (92) on the back, and the digital camera (1) is attached to the front of the digital camera (9). It is possible to process information from the digital camera (1) by wireless communication with 1). In addition, an image taken by the digital camera (1) can be displayed on the screen (91) of the information processing device (9).

  When the digital camera (1) is suction fixed to the mounting surface (90) of the information processing device (9), as shown in FIG. 8, the suction surface (50) of the suction member (5) and the elastic member (6) are bonded. With the surface (60) facing the mounting surface (90), the camera body (2) is pressed toward the mounting surface (90) as shown by an arrow P in FIG.

  As a result, the suction member (5) is elastically deformed in the vertical direction so that the suction surface (50) of the suction member (5) is in close contact with the attachment surface (90) and is formed between the attachment surface (90). The volume of the internal space (54) is reduced, and part of the air in the internal space (54) is discharged. Further, the elastic member (6) is compressed in the vertical direction and elastically deformed, and the elastic repulsive force brings the pressure contact surface (60) of the elastic member (6) into pressure contact with the mounting surface (90).

In this state, when the pressing force on the camera body (2) is released, the suction member (5) is slightly elastically restored, but the internal space (54) of the suction member (5) expands to become negative pressure. Thus, the suction member (5) is not further elastically deformed, and the negative pressure in the internal space (54) is maintained while the suction surface (50) is in close contact with the mounting surface (90). As a result, the adsorbing member (5) is strongly adsorbed to the mounting surface (90).
Moreover, the state where the crimping surface (60) of the elastic member (6) is in pressure contact with the mounting surface (90) is also maintained.
In this way, the digital camera (1) is sucked and fixed to the mounting surface (90).

In this state, as indicated by an arrow F1 in FIG. 10, it is assumed that a large tensile force perpendicular to the mounting surface (90) acts on the camera body (2) and the adsorbing member (5) is elastically deformed in the vertical direction. However, since the adsorbing member (5) has great elasticity, the adsorbing surface (50) is kept in close contact with the mounting surface (90), and the negative pressure in the internal space (54) is destroyed. There is no.
Therefore, the digital camera (1) does not come off from the mounting surface (90).
It should be noted that the elastic member (6) is elastically restored along with the elastic deformation of the adsorbing member (5), and the pressure contact force of the pressure-bonding surface (60) against the mounting surface (90) is weakened. There is no effect.

Further, as shown by the arrow F2 in FIG. 10, the elastic member (6) has a large elastic coefficient even if a large external force in the direction along the mounting surface (90) acts on the camera body (2). In addition, since the crimping surface (60) is in pressure contact with the mounting surface (90), it is hardly elastically deformed in the direction along the mounting surface (90). Therefore, the adsorption member (5) is hardly elastically deformed in the direction along the attachment surface (90), and thereby the state where the adsorption surface (50) is in close contact with the attachment surface (90) is maintained and the internal space (54) is maintained. The negative pressure of will not be destroyed.
Therefore, the digital camera (1) does not come off from the mounting surface (90).

When the digital camera (1) is removed from the mounting surface (90), the suction release piece (7) is pushed into the camera body (2) as shown by an arrow B in FIG. The rib portion (53) of the suction member (5) is pressed by the tip of the suction release piece (7). Here, since the adsorbing member (5) is formed of a material that is easily elastically deformed, the skirt (52) is easily elastically deformed, and the negative pressure in the internal space (54) is destroyed.
As a result, the suction force of the suction member (5) is reduced to almost zero, and the digital camera (1) is detached from the mounting surface (90).

  The digital camera (1) can be fixed to a mounting surface other than the information processing device (9), for example, a vertical wall surface or a desk surface. Similarly, high suction performance can be achieved regardless of the direction of external force. can get.

  According to the digital camera (1) described above, excellent adsorption performance can be obtained not only in the direction perpendicular to the mounting surface (90) but also in the direction of the external force. Therefore, regardless of the orientation of the mounting surface (90) and the acting direction of the external force, a highly versatile suction fixing can be realized.

  In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim. For example, in the above-described embodiment, the elastic member (6) that surrounds the adsorption member (5) and extends in a ring shape is used. However, the present invention is not limited to this, and a plurality of portions surrounding the adsorption member (5) The structure which has arrange | positioned the elastic member is employable.
