JPH0647891U - Button structure with click - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to obtain a button that has a click feeling and can be made thin. A button spring is used as a leaf spring, and a step portion or a groove portion having a click feeling is provided on a contact surface in a range where a contact of the leaf spring moves by sliding a button. [Effect] By adding a simple shape such as a stepped portion, a groove portion, a convex portion, a click feeling can be easily obtained, and further, an effect of reducing the thickness and reducing the number of parts can be obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a button structure mounted on a case and sliding in the axial direction.

[0002]

[Prior art]

 The button structure that is attached to a conventional case and slides in the axial direction has a structure as shown in FIG. That is, in FIG. 4, 41 is a case having a button hole 41a, 42 is a button having a button shaft 42a penetrating the case 41, and 43 is a bending amount in the button axial direction between the case 41 and the button 42. Is a coil spring, 44 is a packing, and 45 is a button retaining ring.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technology, the coil spring simply expands and contracts in response to the sliding of the button, and the click feeling cannot be obtained. If the click feeling is required, a click mechanism has to be provided in the internal switch section or the like. It was Further, in the case of a coil spring, it is necessary to secure a long holding length, which is an obstacle to making the button portion thinner.

Therefore, the present invention solves such a problem, and an object thereof is to provide a thin button having a click feeling.

[0005]

[Means for Solving the Problems]

 The button structure with a click according to the present invention is a button structure that is attached to a case and slides in the axial direction. A part of a plate-shaped spring member provided between members whose gap distance fluctuates by sliding the button is bent. A leaf spring portion having a bending amount between the members is provided, and a step portion or a groove portion is provided on the member on the side where the leaf spring portion is in contact, within the range in which the contact of the leaf spring portion is moved by sliding the button. Characterize.

Embodiment 1 FIG. 1 is a sectional view of an essential part showing an embodiment of the present invention, in which 11 is a case having a button hole 11a, 12 is a button shaft having a button shaft 12a which slides through the case 11. , 13 are button springs in which one or more spring portions 13a having a bending amount are provided between the button lower surface 12b and the button cover surface 11b of the case 11, and 12 slides A are provided on the button cover 11b. Thus, the click step portion 11C is provided in the range B where the contact point C of the leaf spring portion 13a moves. The material of the button spring 13 is preferably a highly corrosion-resistant metal spring member such as S-flex material, and it is preferable to secure a wide general portion for receiving the button lower surface 12b other than the leaf spring portion 13a. Further, the step portion 11C for clicking may be provided with a slope for climbing a leaf spring, and may be a groove 11d for clicking or a convex portion for clicking other than the step portion. 14 is a packing and 15 is a button retaining ring. FIG. 2 is a partial cross-sectional view of an essential part of another embodiment of the present invention, in which a reference numeral 20 is a click plate having a click protrusion 20a disposed inside a button cover 21a of a case 21, and a reference numeral 23 is a click. The button spring is provided with a spring portion 23a having a bending amount with the plate 20. The number of click projections 20a does not always have to be the number corresponding to the spring portion 23a, and it suffices if there is one or more locations. It is preferable to put it. Further, instead of the click plate, a metal pin having excellent wear resistance may be driven into the case. FIG. 3 is a partial cross-sectional view of an essential part showing another embodiment of the present invention, in which 31 is a case, 32 is a button having a button shaft 32a penetrating a button hole 31a provided in the case 31, and 30 Is a click plate which is installed inside the case and has a step portion 30a for click, and 33 is detachably engaged with an engaging groove 32b provided at the tip of the button shaft protruding inside the case, and between the click plate 30 and A button spring 34 having a spring portion that comes into contact with a certain amount of flexure, and 34 is a packing. The click plate may be used in combination with a part of the interior parts, and the shape thereof may be a groove shape, a convex shape, a pin or the like as described above.

[0007]

[Effect of device]

 As described above, according to the present invention, a part of a plate-shaped spring member provided between members whose clearance is changed by sliding a button is bent, and a plate having a bending amount between the members is bent. A spring portion is provided, and a step or groove is provided in the member on the side where the leaf spring portion comes into contact, within the range in which the contact of the leaf spring portion moves when the button slides. The contact point of the spring portion passes through the stepped portion or groove portion, and a click feeling can be obtained. In addition, the click step, groove or protrusion, and leaf spring can be easily processed, and the cost is the same as in the past. When the case is made of plastic as shown in FIG. 2 of the embodiment, wear resistance is improved by using a metallic click plate, and as shown in FIG. 3 of the embodiment, the number of parts is also reduced by using a conventional button retaining ring. it can. In addition, the conventional coil springs are not comfortable to sit in due to their properties, and especially when the planar shape of the button is large, the button may be tilted or wobbled, which makes it unnecessary to use a plurality of coil springs. Although it did not happen, in the case of the leaf spring of the present invention, the number and arrangement of the leaf spring portions to be bent can be freely set, and stable correspondence to various button shapes can be taken. Further, in the embodiment shown in FIG. 3, when the click interference part of the leaf spring and the click plate is provided, the position of the click interference part can be adjusted by providing a degree of freedom for the click plate to slide in the plane direction. It is also possible to automatically synchronize the click timings at multiple points with respect to the shift. Furthermore, since the leaf spring can be used to make the storage space thin, the button portion as a whole can be made thin. Thus, the practical effect of the present invention is extremely large.
