Description

[Technical field]

[0001] The present invention relates to a bell that is attached to the handlebars of a bicycle. [Background technology]

[0002] Bicycle bells that have been proposed so far include a hammer-shaped striker as shown in Patent Document 1, and a spherical striker as disclosed in Patent Document 2. To strike the bell body with such a hammer-shaped striker or spherical striker, it is necessary to use your fingertips to pull the striker or striker away from the bell body. This is not a problem if you have enough time to position your fingertips in advance to the position of the striker or striker, but in urgent cases, it can be difficult to ring the bell.

[0003] [Patent Document 1] Japanese Patent No. 6441974 [Patent Document 2] Japan Utility Model Registration No. 2580455 Summary of the Invention [Problem to be solved by the invention]

[0004] To provide a bicycle bell that is easy to ring and has an excellent design. [Means for solving the problem]

[0005] The bicycle bell of the present invention comprises a mounting bracket for attachment to the handlebars of a bicycle, a bell body directly or indirectly connected to the mounting bracket, and a striking member for striking the bell body, the striking member being a plate body or a case body that is elastically supported by the bell body or the mounting bracket. In the present invention, the striking member is a plate body or a case body that is elastically supported, so that the bell can be rung by simply tapping the plate body or the case body lightly from above.

[0006] In the present invention, the striking member may be a plate body disposed opposite the bell body with a predetermined gap therebetween. This allows the bell to ring simply by gently tapping part of the striking member made of a plate from above. In the present invention, the mode of elastically supporting the striking member on the bell body or case body is for lightly striking the striking member towards the bell body, as described above, and the striking member may be directly connected to the bell body or mounting fixture by an elastic member such as a spring or elastic rubber, or the striking member may be indirectly elastically supported by connecting it to the bell body by a shaft or the like and biasing it away from the bell by an elastic member such as a spring. Also, the striking member may be a case body, and the bell body may be disposed inside the case body.

[0007] In the present invention, the bell body may be dish-shaped or shallow bowl-shaped. In this way, a sound can be produced simply by lightly tapping the striking member against the outer edge of the bell body. The bell body may also be in the form of a plate having a raised portion on its outer edge facing the striking member, in which case the center of the striking member and the center of the bell body may be offset from each other. As long as the bottom of the bell body is plate-shaped and has a raised portion along the outer edge, there is no limit to its external shape, which may be circular, rectangular, square, star-shaped, polygonal, etc. In this case, it is preferable that the striking member has a striking projection that protrudes toward the bell body. Furthermore, by providing the bell body with a difference in thickness, such as thick and thin sections, or by providing it with multiple holes or slits, it is possible to make the volume and tone of the sound change when the part that is struck changes. Furthermore, for example, by rotatably connecting the striking member and the bell body to each other, the position at which they strike each other can be changed, thereby changing the volume and tone of the sound. In this case, the rotation may be continuous or may be stepwise by using a latch mechanism or the like. Also, for example, the striking member and the bell body may be made slidable relative to each other in the left-right or front-back direction, etc., so that the preferred sound can be selected by changing the amount of sliding. Since the present invention is characterized in that the bell rings when the striking member is lightly struck, it also includes a form in which the bell body has multiple bell elements, the striking member has multiple strikers, and when the striking member is struck, the strikers come into contact with the bell elements to ring, and a form in which the striking member is supported by a shaft member and has strikers that move forward and backward toward the bell body as the shaft member moves up and down. Effect of the Invention

[0008] The bicycle bell of the present invention can be rung by simply tapping the striking member lightly with a hand or finger, making it easy to ring the bell even in an emergency. [Brief description of the drawings]

[0010] An example of the structure of a bicycle bell according to the present invention will be described below with reference to the drawings, but the present invention is not limited thereto.

[0011] FIG. 1 shows a side view, FIG. 2 shows a cross-sectional view, FIG. 3 shows an example of a component configuration, and FIG. 4 shows an external perspective view (Example 1). The bicycle bell of the present invention comprises an attachment device 10 for attachment to the handlebars of a bicycle, and a bell body 20 connected to the attachment device. The upper side of the bell body 20 has striking members 30 arranged in parallel and facing each other with a predetermined distance between them. As shown in the cross-sectional view of FIG. 2, the striking member 30 is connected to a bolt-shaped shaft member 41, and the striking member 30 is biased in the separating direction (upward) by a spring 42 arranged on the outer periphery of the shaft member 41. As shown in FIG. 3, the shaft member 41 has a bolt-shaped head 41a and a threaded portion 41b on the tip side. This shaft member 41 is capable of moving up and down along an insertion hole 21 a provided in the center of bell body 20 . As explained with reference to Figure 3, a bolt-shaped shaft member 41 is inserted into insertion hole 21 of bell body 20, and then into spring 42, with threaded portion 41b at the tip being screwed into female thread portion 33 of striking member 30. Head 41a of shaft member 41 is restricted by step portion 21b provided inside insertion hole 21a of bell body 20, and the lower end of spring 42 is held by restriction portion 21c on the upper side of insertion hole 21a of the bell body. As a result, when striking member 30 is lightly struck from above with a hand or finger, striking member 30, biased by spring 42, strikes bell body 20, causing the bell to ring. In this embodiment, the elastic support part 40 is made up of a shaft and a spring, but as long as the striking member 30 is elastically supported, the bell body and the striking member may be directly connected by an elastic member. If striking member 30 and bell body 20 were directly connected by an elastic member, striking member 30 would strike the bell body at an angle.

[0012] In this embodiment, the bell body 20 and the striking member 30 both have a circular outer shape and are disposed opposite each other. The bell body 20 is an example in which a ring-shaped raised portion 23 is formed along the outer peripheral edge of the plate-shaped bottom portion 22, but it may be in the shape of a shallow bowl or a dish as long as a recess 24 is formed on the inside. The material of the bell body 20 is preferably a metal such as a copper alloy.

[0013] The striking member 30 has a striking projection 32 along the outer periphery of a plate-like base portion 31 at a position opposite the raised portion 23 of the bell body.

[0014] FIG. 5 shows an example of how the bicycle bell according to the present invention is attached to a handlebar. As shown in FIG. 3, mounting fixture 10 has semicircular upper frame 11 and lower frame 12 which can be opened and closed at pivot part 13, and upper frame 11 has mounting recess 11b into which support part 21 of bell body 20 is fitted, but there are no limitations on the mounting structure of bell body 20. As shown in FIG. 5(a), one end of the upper frame 11 and the lower frame 12 are spread apart from each other and attached so as to sandwich the periphery of the handle 1, and the fastening portion 11a of the upper frame 11 and the fastening portion 12a of the lower frame 12 are fastened with fastening members 14 such as screws, thereby fixing the frame to the handle.

[0015] FIG. 6 shows an application example of the bell body 20. (b) shows an example of a bell body 20A provided with a slit portion 25, and (c) shows a bell body 20B in which the thickness of raised portion 23 is differentiated between thick portion 23a and thin portion 23b, etc., so that the tone changes when the striking position is changed. The external shape is not limited to a circle, but may be a square, a rectangle, a polygon, or the like. Furthermore, as long as striking member 30 is disposed opposite bell body 20, it may be shaped like a steering wheel of a car, with the outer ring supported by a plurality of rims 31a, like striking member 30A shown in FIG.

[0016] The bell body 20 and striking member 30 described above are examples in which the external shapes are generally identical, but as shown in Figures 8 and 9, for example, one or both of the striking member 30 and the bell body 20 may be made to have a partially elliptical external shape or may have a recess so that sound generated inside can be more easily transmitted to the outside. In this embodiment, as shown in the plan view of Figure 8, the outer edge of the bell body 20 is positioned so that it protrudes slightly outward from the outer edge of the striking member 30, making it easier for the internal sound to resonate outward through the gap d.

[0017] A second embodiment of a bicycle bell according to the present invention is shown in FIG. Figure 10(a) shows the external view, (b) shows a cross-sectional view, and (c) shows the hammered state. In this embodiment, a circular plate-shaped bell body 20 is spaced at a predetermined distance from the striking members 30, which are arranged opposite each other, and are supported on the mounting fixture 10 side by elastic members 51 in the form of wires or leaf springs. In this embodiment, the striking member 30 is elastically supported from the connection portion that connects the bell body 20 to the mounting fixture 10. In this embodiment, striking member 30 also consists of a plate body, and when it is lightly struck in the direction f as shown in Figure 10(c) in the state shown in Figure 10(b), elastic member 51 deforms and striking member 30 hits bell body 20, but then elastically returns to the state shown in Figure 10(b).

[0018] Example 3 is shown in FIG. This embodiment is also an example in which the striking member 30 is elastically supported on the mounting fixture side by an elastic member 52 made of a wire or a leaf spring, and as shown in the perspective view of FIG. 11(d), the operation button 61 is elastically supported by an elastic member 52a, and the striking member 30 is supported below the operation button 61 by a branched elastic member 52b. In this way, the bell can be rung either by hitting the striking member 30 directly or by hitting the operating button 61.

[0019] Example 4 is shown in FIG. In this embodiment, a substantially L-shaped base member 62 is connected to the mounting fixture 10 . A spherical recess 62a is provided at one end of base member 62, and spherical connecting portion 25 provided on the back surface of bell body 20 is supported in sliding contact with this spherical recess 62a. In this example, a hitting member 30 that is elastically supported by a spring 42 via a shaft 41 is disposed at the other end of the base member 62 . In this way, when the striking member 30, which is positioned offset from the bell body 20, is struck from above in the direction f, the back surface of the striking member 30 hits the end of the bell body 20, as shown in the transition from the state in Figure 12(b) to the state in Figure 12(c), and the bell rings. The bell body 20 is ball-connected so that it returns to the horizontal direction, so that the vibration of the bell body 20 is prolonged.

[0020] Example 5 is shown in FIG. In this embodiment, a bell body is formed by supporting a base member 63 on a mounting fixture 111 side by a spring 42 via a shaft 41, from which a plurality of bell elements 121 are erected. In this embodiment, bell element 121 is bowl-shaped. In this case, the striking member 30 disposed opposite the base member 63 serves as a case body, and a plurality of striking elements 122 that also act as bell elements are disposed inside the case body. Each striker 122 is disposed opposite a corresponding bell element 121 .

[0021] Example 6 is shown in FIG. This embodiment is a modification of the bell element and the striker in the fifth embodiment, in which the convex portion of the bell element 121a and the convex portion of the striker 122a are disposed opposite each other.

[0022] Example 7 is shown in FIG. In this embodiment, a plurality of bell elements 123a to 123d are arranged on a shaft 41 that elastically supports the striking member 30 between a base member 63 and the striking member 30 arranged opposite the base member 63. When the striking member 30 is struck, the plurality of tambourine-shaped bell elements hit each other and ring a bell.

[0023] Example 8 is shown in FIG. In this embodiment, the bell body 20 is shaped like a bowl with an open bottom, and a striker 131 is disposed inside the bowl. The striking members 131 are a pair of striking members 131, 131, which are connected to each other by a spring 42 so as to face each other as shown in FIG. The striking member 30 is connected to a hollow shaft 34 and is connected to a shaft 41 so as to be slidable inside the hollow shaft 34 . The lower end of the shaft 41 is connected and fixed to a base member 64 on the mounting tool side, and the lower end of a striker 131 is axially attached to a sub-base member 65 disposed above the base member 64. As a result, in the state shown in Figure 16(b), the pair of strikers 131, 131 are separated from the inside of the bell body 20 due to the tensile force of the spring 42, but when the striking member 30 is struck and moves downward as shown in Figure 16(c), the lower end of the hollow shaft 34 hits the pair of strikers 131, 131, and they move apart from each other. As a result, the upper end of the striker 131 hits the bell body 20, causing the bell to ring.

[0024] Example 9 is shown in FIG. In this embodiment, the hitting member 30 is a cylindrical case body that is open at the bottom. In this example, bell body 20 is attached to the inside of the case body via shaft 41 that supports the case body. The shaft 41 is connected to a base member 66 on the attachment side by a spring 42 in a state in which the shaft 41 is biased upward. A striking plate 132a is connected to the shaft 41. In addition, a roughly L-shaped striker 132 is axially attached to the base member 66, and when the operating rod 132b of this striker 132 hits the striking board 132a, the tip side of the striker 132 hits the bell body 20.

[0025] Example 10 is shown in FIG. This embodiment has a plurality of bell elements 20 standing upright from a base member 67 on the mounting fixture side by an elastic member 221 such as a wire, and these bell elements 20 are arranged inside a striking member 30 consisting of a case body. In this embodiment, a plurality of striking members 132 are disposed on the ceiling surface inside the case body, and when the striking members descend, they strike the bell element 20 supported by a wire, producing a sound.

[0026] Example 11 is shown in FIG. The present invention is characterized in that the striking member is a plate-like or case-like member, and this embodiment is an example in which the striking member 30 is a spherical case-like member. The striking member 30 is elastically supported on the mounting fixture 10 side by an elastic support portion 40 such as a spring. This is an example in which a bell-shaped bell body 20 is built inside the striking member 30 consisting of this case body so as to be freely movable. With this, when the elastically supported hollow spherical striking member 30 is lightly struck, the built-in spherical bell (20) rolls and makes a sound. In addition, the striking member 30 is provided with a plurality of slits 34 to facilitate sound production. [Industrial Applicability]

[0027] The bell according to the present invention can be used as a bell for various bicycles because it produces a sound simply by lightly striking the striking member.
