This allows for the miniaturization of the mounting device (1, 2, 3) that functions as a whistle.

Description

Technical Field

[0001] The present invention relates to a belt mounting device for mounting on at least one belt body. Background Technology

[0002] As belt mounting devices used for installation on belts (including belts), known types include buckles that connect two ends of the belt and adjusters that adjust the length of the belt. Generally, buckles have a plug and a socket that engages the plug in a detachable manner, allowing the two ends of the belt to be connected and separated. Such buckles are installed on belts of products such as helmets, backpacks, and neck straps.

[0003] As one type of buckle, it is known to have a whistle-emitting function, so that it is easy for others to know that there is an emergency and that help is needed, such as at construction sites or during outdoor activities like mountain climbing. Furthermore, as an example of such a buckle with a whistle function, it is disclosed in U.S. Patent No. 6,668,428 (Patent Document 1). Figure 27 The buckle 120 shown here has a whistle.

[0004] Patent Document 1 describes a buckle with a plug portion and a socket portion that can be engaged and disengaged. The socket portion includes: a socket body portion that engages and houses the plug portion; a strap retainer portion that mounts and retains the strap body; and a whistle portion disposed between the socket body portion and the strap retainer portion. The whistle portion has an inlet for introducing air (breath) into the whistle portion and an outlet for discharging air from the whistle portion.

[0005] The buckle 120 of Patent Document 1 has a plug portion 121 and a socket portion 122 that can be engaged and disengaged. The socket portion 122 has: a socket body portion 122a, which engages and stores the plug portion 121; a strap retaining portion 122b, which mounts and retains the strap body; and a whistle portion 122c, which is disposed between the socket body portion 122a and the strap retaining portion 122b. The whistle portion 122c is provided with a blow-in port 122d for introducing air (breath) into the whistle portion 122c and an exhaust port 122e for discharging air from the whistle portion 122c.

[0006] In the buckle 120 of Patent Document 1, the whistle portion 122c, which has a blow-inlet 122d and an outlet 122e, is disposed between the socket body 122a and the strap retainer 122b in a form that is separate from the function of the socket body 122a and the strap retainer 122b. As a result, it is possible to prevent the blow-inlet 122d and the outlet 122e of the whistle portion 122c from being covered and blocked by the strap body held in the strap retainer 122b and the strap body held in the plug portion 121, so that the whistle portion 122c can work stably.

[0009] Patent Document 1: US Patent No. 6,668,428 Summary of the Invention

[0010] The problem the invention aims to solve

[0011] In conventional buckles with a whistle function, such as those in Patent Document 1, the whistle portion is provided as an additional component to the main buckle components—the socket portion, plug portion, and belt retaining portion. Furthermore, the whistle's inlet and outlet are positioned to prevent blockage by the belt body. Moreover, the whistle portion itself is relatively large. As a result, the buckle is larger in size.

[0012] The present invention was made in view of the above-mentioned problems, and its object is to provide a mounting device that has a whistle function and a structure that is smaller than that of the past.

[0013] Solution for solving the problem

[0014] To achieve the above objectives, the belt mounting device provided by the present invention is a belt mounting device installed on at least one belt body, wherein the belt mounting device has: at least one crossbar portion extending along a first direction and contacting the belt body; a pair of side support portions connected to both ends of the crossbar portion and supporting the crossbar portion; and a whistle portion having an air inlet and an air outlet, the whistle portion having a cavity portion for increasing the pressure of air introduced from the air inlet, the cavity portion being disposed downstream of the air flow direction relative to the air outlet, the cavity portion being disposed on at least a portion of the crossbar portion and the pair of side support portions.

[0015] In the belt mounting device of the present invention, preferably, the pair of side supports have inner edges opposite to each other when the belt mounting device is viewed from above, the inlet and the outlet are arranged in the first direction at a position further outward than the position of the inner edge of the side support, and at least a portion of the cavity is provided in at least a portion of the side support.

[0016] Alternatively, preferably, the mouthpiece protrudes from one of the pair of side supports, and at least a portion of the mouthpiece is provided with the inlet and the outlet.

[0017] Furthermore, preferably, the cavity portion is disposed in at least a portion of the side support portion and at least a portion of the crossbar portion.

[0018] In the mounting device of the present invention, it is preferred that the whistle part is formed by assembling at least two components together.

[0019] In this case, preferably, the whistle part has: a whistle body part including the inlet and the outlet; and a guide member formed integrally with the whistle body part and assembled within the whistle body part, the guide member having an inclined guide portion that guides the air introduced from the inlet toward the outlet.

[0020] Alternatively, in this case, it is preferable that the guide member has at least one engaging protrusion or at least one engaging hole, and the whistle body has at least one engaging hole that engages with the engaging protrusion of the guide member, or at least one engaging protrusion that engages with the engaging hole of the guide member.

[0021] Preferably, the belt installation device of the present invention is a buckle that connects the two parts of the belt body in a separable manner, or an adjuster that can adjust the length of the belt body.

[0022] The effects of the invention

[0023] According to the present invention, it is possible to provide a mounting device that has a whistle function and a structure that is smaller than before. Attached Figure Description

[0051] The following are examples and references to the appendix. Figure 1 An example of an embodiment of the present invention will be described below. Furthermore, the present invention is not limited to the embodiments described below; various modifications can be made as long as the invention has a substantially the same structure and achieves the same effect.

[0052] In this invention, a strap mounting device is a component that is installed on at least one strap in products such as helmets, backpacks, and clothing for connecting and adjusting the length of the strap. For example, a strap mounting device may include a buckle that detachably connects the ends of the straps located at two parts of one or two straps, and an adjuster that is installed on one or two straps to adjust the length of the strap.

[0053] In addition, a belt body refers to a component that has a flat and elongated strip-like shape and is flexible. For example, belt bodies include strip-shaped fabrics, strip-shaped braids, and belts made of natural or synthetic leather.

[0054] In the following description related to belt mounting devices, the front-back direction refers to the direction along the length of the belt when the belt with the mounting device is stretched in a straight line. The front-back direction can be referred to as the length direction of the belt mounting device. Furthermore, when the belt mounting device is a buckle, the direction where the plug of the buckle is closer to the socket is defined as front, and the direction where the plug is further away from the socket is defined as rear.

[0055] The vertical direction refers to the surface direction of the belt body when it is stretched as described above. Furthermore, if the belt mounting fixture has an outward-facing side when installed onto the belt body, the direction facing outward is defined as "upward," and the direction opposite to "upward" is defined as "downward." The vertical direction can be referred to as the thickness direction of the belt mounting fixture.

[0056] The left-right direction is orthogonal to the aforementioned front-back and up-down directions. Especially in the case of this invention, the left-right direction is the direction in which the crossbar extends, which is provided for winding or pressing the belt body onto the belt mounting device. The left-right direction can be referred to as the width direction of the belt mounting device.

[0057] If further explained with reference to the accompanying drawings, the front-back direction, up-down direction, and left-right direction of the mounting device refer to the directions of the mounting device. Figure 2 and Figure 21 The paper has vertical, horizontal, and left-right directions. In addition, in this invention, the left-right direction in which the crossbar extends is referred to as the first direction. Furthermore, when viewing the mounting device from above, the direction orthogonal to the first direction (e.g., the direction in which the plug is close to or away from the socket) is sometimes referred to as the second direction.

[0058] Example 1

[0059] Figures 1-3 These are schematic perspective views, top views, and side views of the buckle (with mounting device) of Embodiment 1. Figures 4-9 This is a schematic diagram showing the plug portion of the buckle in this embodiment 1 from various angles.

[0060] The belt installation device 1 in this embodiment 1 is a buckle 1 that connects the two ends of a belt body or the ends of two belt bodies in a detachable manner.

[0061] The buckle (with mounting hardware) 1 of this embodiment has a plug portion 10 mounted on a strap body (not shown) and a socket portion 40 mounted on a strap body (not shown), and has a structure that allows the plug portion 10 to be detachably engaged with the socket portion 40 for storage. The plug portion 10 and the socket portion 40 are formed of a thermoplastic resin such as polyaldehyde, polyamide, or polypropylene. Furthermore, in this invention, the material of the mounting hardware is not limited.

[0062] like Figures 4-9 As shown, the plug portion 10 of this embodiment 1 has: a plug-side strap retaining portion 11, which mounts and retains the strap body; and a locking portion 21, which extends forward (to one of the second directions) from the plug-side strap retaining portion 11. In this case, the plug-side strap retaining portion 11 is formed from the portion of the plug portion 10 that is not housed within the socket portion 40.

[0063] In the plug-side strap holding portion 11, the whistle portion 30, which produces sound due to the blowing of air, is integrally provided in the plug-side strap holding portion 11 using a portion of the shape required to hold the strap body in the plug-side strap holding portion 11. As will be discussed later, the whistle portion 30 is formed by... Figure 11 The guide member 35 shown is assembled inside the whistle body 31, which will be discussed later, of the plug portion 10.

[0064] The plug-side retaining portion 11 has: two crossbar portions 12 extending along the width direction; a pair of left and right side support portions 13 connected to the left and right ends of each crossbar portion 12; a mouthpiece portion (blow-in portion) 14 protruding from one (right) side support portion 13 outward (right) in the width direction; and two band through grooves 15 formed between the left and right side support portions 13.

[0065] In this embodiment 1, the crossbar portion 12 has a first crossbar portion 12a disposed on the side near the engaging portion 21 and a second crossbar portion 12b disposed on the side away from the engaging portion 21. Furthermore, the through groove 15 has a first through groove 15a disposed between the engaging portion 21 and the first crossbar portion 12a, and a second through groove 15b disposed between the first crossbar portion 12a and the second crossbar portion 12b.

[0066] The first crossbar portion 12a and the second crossbar portion 12b are formed perpendicularly along the width direction and are arranged parallel to each other. Furthermore, the first crossbar portion 12a and the second crossbar portion 12b are arranged with different positions in the length direction and thickness direction. In this case, the first crossbar portion 12a is positioned higher (outer) than the second crossbar portion 12b.

[0067] The first crossbar portion 12a and the second crossbar portion 12b are connected and fixed to the left and right side support portions 13 via their respective left and right ends (one end and the other end), and are supported on the left and right side support portions 13. In the plug-side strap holding portion 11 of this embodiment 1, a portion of the strap is wound around the first crossbar portion 12a in contact with the first crossbar portion 12a. In addition, the two strap portions that fold back at the first crossbar portion 12a pass through the lower surface of the second crossbar portion 12b, thereby contacting the lower surface of the second crossbar portion 12b. Thus, the strap is held in the plug-side strap holding portion 11. Furthermore, the length of the strap can be adjusted by changing the position of the strap wound around the first crossbar portion 12a.

[0068] Furthermore, in this invention, the length (length direction) and thickness (thickness direction) of each crossbar portion 12 are not particularly limited. The connection position of each crossbar portion 12 to the left and right side support portions 13 is also not particularly limited. Alternatively, at least one of the first crossbar portion 12a and the second crossbar portion 12b may be connected to the left and right side support portions 13, for example, via a rotation axis, thereby being rotatably supported on the side support portions 13 about the rotation axis. Additionally, the plug-side strap retaining portion 11 may be configured to have only one crossbar portion 12, or have three or more crossbar portions 12.

[0069] In this embodiment 1, the first crossbar portion 12a has an internal space 19 continuously formed along the width direction, which forms part of the cavity portion 34 of the whistle portion 30 (see reference). Figure 9 The internal space 19 of the first crossbar portion 12a communicates with the internal space 19 of the side support portion 13 provided on the right side. Furthermore, the internal space 19 of the first crossbar portion 12a is continuously formed in the width direction (first direction) to the position of the inner edge 13a (inner surface) of the side support portion 13 on the left side. The second crossbar portion 12b does not have an internal space 19 and is formed solidly.

[0070] The left and right side support portions 13 are positioned apart from each other in the width direction and are formed parallel to each other along a length direction orthogonal to the width direction (i.e., a second direction orthogonal to the first direction). The left and right side support portions 13 are provided from the front end of the first through-slot 15a to the rear end of the second crossbar portion 12b in the length direction. That is, the side support portions 13 in the plug portion 10 are such that they support the first crossbar portion 12a and the second crossbar portion 12b, and are continuously formed throughout the entire length direction forming the first through-slot 15a, the first crossbar portion 12a, the second through-slot 15b, and the second crossbar portion 12b.

[0071] The left and right side support portions 13 are located on the top of the plug portion 10 ( Figure 5 Each side support 13 has an inner edge (inner surface) 13a arranged opposite to each other and an outer edge (outer surface) facing outward in the width direction. An internal space 19 is provided in the right-side side support 13. The left-side side support 13 does not have an internal space 19 and is formed solidly.

[0072] The mouthpiece 14 protrudes outward (to the right) from the right-side side support 13 in the width direction. Furthermore, the mouthpiece 14 has a base end portion connected to the side support 13 and a tip portion positioned furthest from the side support 13, and has a shape that tapers outward in the width direction, with the tip portion being thinner than the base end portion. The mouthpiece 14 protrudes to the right from the side of the side support 13 opposite to the connection position with the first crossbar portion 12a in the width direction. Therefore, as will be discussed later, the internal space 19 of the mouthpiece 14, the internal space 19 of the right-side side support 13, and the internal space 19 of the first crossbar portion 12a can be stably connected to each other.

[0073] In this case, looking down at the plug portion 10 ( Figure 5When the first crossbar portion 12a is connected to the right side support portion 13, the length dimension of the connection area is smaller than the length dimension of the base end of the mouthpiece portion 14. In addition, the connection area of ​​the first crossbar portion 12a is included in the formation range of the base end of the mouthpiece portion 14 in the length direction.

[0074] An air inlet 32 ​​for blowing air into the whistle section 30 is formed at the top of the mouthpiece portion 14. This air inlet 32 ​​opens outwards in the width direction. The mouthpiece portion 14 and the side support portion 13 on the right side, as shown... Figure 10 As shown, an internal space 19 is provided along the width direction, communicating with the inlet 32 ​​of the mouthpiece 14 and the internal space 19 of the first crossbar 12a. The mouthpiece 14 and the side support 13 are installed within the internal space 19 of the mouthpiece 14 and the side support 13. Figure 11 The guide member 35 shown.

[0075] An outlet 33 is provided on the upper surface of the mouthpiece 14 and the upper surface of the right-side side support 13 to discharge air blown in from the inlet 32. The outlet 33 spans both the mouthpiece 14 and the right-side side support 13 and communicates with the internal space 19 provided in both the mouthpiece 14 and the right-side side support 13. The outlet 33's location on the upper surfaces of the mouthpiece 14 and the side support 13 allows the user of the buckle 1 of this embodiment to easily identify that the buckle 1 has a whistle function.

[0076] The outlet 33 is provided with an edge portion 33a that separates the flow of air introduced from the inlet 32 ​​vertically, and an inclined surface 33b that slopes along the width direction from the edge portion 33a. In this case, the edge portion 33a is disposed at the boundary between the inner wall surface of the inner space 19 surrounding the whistle portion 30 and the inclined surface 33b. More specifically, the edge portion 33a is formed on the portion of the opening edge on the inner wall side of the outlet 33 near the first crossbar portion 12a (in other words, the downstream portion in the air flow direction).

[0077] The inclined surface 33b of the outlet 33 slopes upward from the edge portion 33a toward the inside of the plug portion 10 in the width direction (see reference). Figure 9 and Figure 10 The inclined surface 33b is located at the top of the plug portion 10 ( Figure 5 The outlet 33 is located within the width direction between the position of the inner edge (inner side surface) 13a and the position of the outer edge (outer side surface) in the side support portion 13 on the right side. The inclined surface 33b of the outlet 33 is formed as a slightly concave curved surface from the edge portion 33a to the upper surface of the side support portion 13.

[0078] The lower surface of the mouthpiece portion 14 is provided with a locking hole portion 14a that engages with the locking protrusion 36a of the guide member 35 (described later). By engaging and fixing the locking protrusion 36a of the guide member 35 with the locking hole portion 14a, the guide member 35 is assembled (fixed) at a predetermined position within the internal space 19 of the mouthpiece portion 14 and the side support portion 13.

[0079] The whistle portion 30, which is located on the plug side with a retaining portion 11, includes: a whistle body portion 31 having an internal space 19; and a guide member 35 assembled to the whistle body portion 31.

[0080] In this embodiment 1, the whistle body 31 is formed as the outer frame of the whistle part 30 using the first crossbar portion 12a in the plug-side strap holding portion 11, a portion of the right-side side support portion 13, and the mouthpiece portion 14. The whistle body (outer frame portion) 31 is provided with the aforementioned inlet 32 ​​and outlet 33. In this embodiment 1, the inlet 32 ​​and outlet 33 of the whistle body 31 (especially the edge portion 33a of the outlet 33) are located on the outer side in the width direction, beyond the position of the inner edge 13a of the right-side side support portion 13. Therefore, when the strap is held to the plug-side strap holding portion 11 of the plug portion 10 as described above, the inlet 32 ​​and outlet 33 of the plug portion 10 are less likely to be covered and blocked by the strap.

[0081] Inside the main body 31 of the whistle, such as Figure 10 As shown, the internal space 19 is continuously formed along the width direction in the first crossbar portion 12a, the side support portion 13, and the mouthpiece portion 14. The internal space 19 of the whistle body portion 31 has a first space portion 19a disposed on the side of the mouthpiece 32 and a second space portion 19b disposed on the inner side of the first space portion 19a (downstream side in the airflow direction). A step portion 19c is formed between the first space portion 19a and the second space portion 19b, which serves as their boundary.

[0082] The first space 19a of the whistle body 31 is a space for receiving the guide member 35, into which it is inserted. Furthermore, a portion of the cavity 34 of the whistle part 30 (described later) is formed by the first space 19a. The second space 19b of the whistle body 31 is positioned further away from the mouthpiece 32 in the width direction than the first space 19a. The second space 19b, together with a portion of the first space 19a, forms the cavity 34 of the whistle part 30. In this case, the step 19c, which forms the boundary between the first space 19a and the second space 19b, is provided on a portion of the inner wall surface surrounding the internal space 19 in a cross-sectional view of the whistle body 31 orthogonal to the width direction (not shown). The step 19c causes one end of the guide member 35 to abut against the whistle body 31 when it is assembled.

[0083] like Figure 11 As shown, the guide member 35 has: a bottom portion 36, which is longer in the width direction; a front wall portion 37 and a rear wall portion 38, which stand upright from the front and rear ends of the bottom portion 36, respectively; an inclined guide portion 39, which is formed between the front wall portion 37 and the rear wall portion 38; and an engaging protrusion 36a, which protrudes downward from the lower surface of the bottom portion 36 (see reference). Figure 9 The front wall portion 37 and the rear wall portion 38 of the guide member 35 are integrally formed in the width direction of the bottom portion 36. The overall width dimension (dimension in the width direction) of the guide member 35 is the same as the width dimension of the first space portion 19a of the whistle body portion 31. That is, the width dimension of the guide member 35 is the same as the width dimension of the whistle body portion 31 from the blowhole 32 to the step portion 19c.

[0084] like Figure 9 As shown, the inclined guide portion 39 of the guide member 35 has an inclined surface that slopes upward from the inlet 32 ​​of the whistle body portion 31 toward the outlet 33. The inclined surface of this inclined guide portion 39 has a certain angle of inclination relative to the width direction. For example, in this embodiment 1, the inclined surface of the inclined guide portion 39 is formed such that the edge portion 33a of the outlet 33 is located at an angle such that the edge portion 33a is located on an extension line formed by imagining the inclined surface extending straight. This inclined guide portion 39 is provided on the guide member 35 to guide the air introduced from the inlet 32 ​​toward the outlet 33, and can increase the flow rate of the air flowing on the inclined guide portion 39. The engaging protrusion 36a of the guide member 35 is formed to engage and fix with the engaging hole portion 14a provided on the lower surface of the mouthpiece portion 14, thereby fixing the size of the guide member 35.

[0085] In this embodiment 1, the whistle section 30 is provided with a cavity (resonance chamber) 34 that increases the air pressure by allowing air separated from the edge portion 33a of the outlet 33 to flow in when air is blown in from the inlet 32 ​​of the whistle section 30. In this case, the cavity section 34 of the whistle section 30 is formed in the direction of airflow, with the edge portion 33a of the outlet 33 as the boundary, and is formed by a portion of the internal space 19 of the whistle section 30 (i.e., the internal space 19 of the first crossbar section 12a, the side support section 13, and the mouthpiece section 14) downstream of the edge portion 33a. In other words, the cavity section 34 of this embodiment 1 is formed by a portion of the internal space 19 of the side support section 13 provided on the right side and the entire internal space 19 of the first crossbar section 12a.

[0086] By configuring the cavity 34 with the whistle section 30 in this way, when air is blown in from the inlet 32, the following alternating processes are repeated: (A) when the pressure inside the cavity 34 is low, air distributed from the edge 33a of the outlet 33 to the side of the cavity 34 flows into the cavity 34, thereby increasing the air pressure; (B) when the pressure inside the cavity 34 increases, air distributed from the edge 33a of the outlet 33 to the outside is discharged together with the air inside the cavity 34, thereby decreasing the pressure inside the cavity 34. This alternating flow of air (A) and air flow (B) creates resonance, thereby enabling smooth sound production at the whistle section 30.

[0087] In particular, in this embodiment 1, the cavity 34 of the whistle section 30 is provided on the entire first crossbar section 12a in the width direction and a part of the side support section 13, ensuring that the volume of the cavity 34 is relatively large. As a result, when air is blown in from the inlet 32, a sound of 3kHz to 4kHz that is relatively easy for a person to hear can be easily generated at the whistle section 30.

[0088] As described above, the whistle portion 30 of this embodiment 1 is formed by inserting the guide member 35 into the mouthpiece 32 and assembling it into the first space portion 19a of the whistle body portion 31. At this time, one end (the left end) of the guide member 35 in the width direction of the bottom part 36, the front wall part 37, and the rear wall part 38 abuts against the stepped part 19c of the whistle body portion 31, and the engaging protrusion 36a of the guide member 35 is fitted and fixed with the engaging hole part 14a provided on the lower surface of the mouthpiece portion 14. Thus, the guide member 35 is fixed in a predetermined position within the whistle body portion 31.

[0089] By mounting the guide member 35 to the whistle body 31, which forms the outer frame, the whistle part 30 can be easily formed with simple operations. Furthermore, the cavity 34 that increases air pressure, the outlet 33 with an edge 33a, and the inclined guide 39 that guides air toward the outlet 33 can be easily provided on the whistle part 30. Therefore, the buckle 1 can stably function as a whistle. In addition, in this case, the molds for forming the whistle body 31 and the guide member 35 can be formed with a relatively simple structure, thus reducing the manufacturing cost of the buckle 1.

[0090] In this embodiment 1, the engaging portion 21 of the plug portion 10 includes: an engaging main body 22 connected to the plug-side retaining portion 11; a pair of left and right legs 23 extending forward from the engaging main body 22; and a plug guide 24 disposed between the left and right legs 23, which guides the insertion direction of the plug portion 10 when it is inserted into the socket portion 40. The engaging main body 22 extends forward from the left and right side support portions 13 in the plug-side retaining portion 11. Furthermore, when viewed from above, the plug portion 10 (… Figure 5 It has a roughly V-shaped form.

[0091] The left and right legs 23 have a shape that is symmetrical to each other in the width direction. Each left and right leg 23 has an operating part 23a that is pressed when the plug part 10 is detached from the socket part 40, and a narrow part 23b that connects the operating part 23a to the engaging body part 22. The operating part 23a is elastically deformable in such a way that it can move inward in at least the width direction. At the top of the operating part 23a, an engaging protrusion 23c that engages with the socket part 40 protrudes upward and downward.

[0092] The plug guide 24 extends forward from the top end (center portion in the width direction) of the engaging body 22. The plug guide 24 is positioned between the left and right legs 23. Furthermore, the plug guide 24 is separated from the left and right legs 23 respectively, with a gap formed between the plug guide 24 and the left and right legs 23. The top end of the plug guide 24 protrudes forward relative to the left and right legs 23, and a left and right protrusion 24a protruding in the width direction is provided at the top end of the plug guide 24.

[0093] The socket portion 40 of this embodiment 1 has a socket-side strap holding portion 41 for mounting and holding the strap body, and a storage portion 51 extending rearward from the socket-side strap holding portion 41. The socket-side strap holding portion 41 has a crossbar portion 42 extending along the width direction and a pair of left and right side support portions 43 connected to the left and right ends of the crossbar portion 42.

[0094] The socket portion 40 has a storage portion 51 comprising: an upper plate portion 52; a lower plate portion 53 disposed separately from the upper plate portion 52; and left and right side wall portions 54 connecting the upper plate portion 52 and the lower plate portion 53. A storage space is formed between the upper plate portion 52 and the lower plate portion 53 for inserting and storing the plug portion 10. The upper plate portion 52 and the lower plate portion 53 have a generally Y-shaped form when the socket portion 40 is viewed from above or below. A rearwardly extending slit portion 55 is provided at the center of the upper plate portion 52 and the lower plate portion 53 in the width direction. An insertion recess (not shown) is provided on the inner surface of the upper plate portion 52 opposite to the lower plate portion 53 for inserting a locking protrusion disposed on the upper surface side of the leg portion 23 of the plug portion 10. An insertion hole (not shown) is provided on the inner surface of the lower plate portion 53 opposite to the upper plate portion 52 for inserting a locking protrusion provided on the lower surface side of the leg portion 23 of the plug portion 10.

[0095] Furthermore, in this embodiment 1, the shape of the engaging portion 21 of the plug portion 10 and the shape of the receptacle portion 51 of the socket portion 40 are not particularly limited. The engaging portion of the plug portion and the receptacle portion of the socket portion in this invention can be formed in a manner that allows the plug portion to engage with the socket portion in a detachable manner.

[0096] According to the buckle 1 of this embodiment 1, which has the plug portion 10 and the socket portion 40 described above, a whistle portion 30 is provided on the plug side of the plug portion 10 with a retaining portion 11. Therefore, air is blown in from the blowing inlet 32 ​​of the whistle portion 30, so that sound can be easily and smoothly produced from the whistle portion 30.

[0097] Furthermore, in the buckle 1 of this embodiment 1, air can be easily blown into the whistle section 30 through the inlet 32, whether the plug portion 10 and the socket portion 40 are engaged or disengaged. Meanwhile, the inlet 32 ​​and outlet 33 of the whistle section 30 are positioned further outward in the width direction than the inner edge 13a of the side support portion 13. Therefore, the inlet 32 ​​and outlet 33 are less likely to be blocked by the strap body held in the plug-side strap holding portion 11 and the strap body held in the socket-side strap holding portion 41. Thus, sound can be produced smoothly when air is blown into the whistle section 30.

[0098] Based on this, in the buckle 1 of this embodiment 1, the cavity portion 34 required for sound generation at the whistle portion 30 is provided in the first crossbar portion 12a and the side support portion 13 required for holding the strap body at the plug portion 10. That is, the whistle portion 30 is formed in a shape that is indispensable to the function of the buckle 1. Therefore, compared with conventional buckles (belt mounting devices) in Patent Document 1, which additionally have a whistle portion relative to the function of the buckle, the buckle 1 of this embodiment 1 can be formed in a smaller size. Therefore, it is possible to achieve miniaturization of the buckle 1 with whistle function (especially miniaturization in the length direction of the buckle 1).

[0099] Furthermore, in this embodiment 1, in order to... Figure 11 The guide member 35 shown is fixed to the whistle body 31. As described above, a locking protrusion 36a is provided on the bottom part 36 of the guide member 35, and a locking hole 14a for engaging and fixing the locking protrusion 36a is provided on the lower surface of the whistle body 31 (mouthpiece part 14). However, in this invention, for example, the locking protrusion may be provided on at least one of the front wall and rear wall of the guide member, and a locking hole may be provided on the part of the whistle body corresponding to the locking protrusion. Alternatively, the locking protrusion may be provided on the whistle body, and the locking hole may be provided on the guide member. Furthermore, in this invention, the method and means of fixing the guide member 35 into the whistle body 31 are not limited, and the guide member 35 may also be fixed into the whistle body 31 by, for example, adhesive or welding.

[0100] In this embodiment 1, the whistle portion 30 is formed on the first crossbar portion 12a of the plug-side strap holding portion 11. However, in this embodiment 1, the whistle portion may also be formed on the second crossbar portion 12b of the plug-side strap holding portion 11 or the crossbar portion 42 of the socket-side strap holding portion 41. Furthermore, in this embodiment 1, the whistle portion 30 may be provided on two or more crossbar portions 12 and 42 of the first crossbar portion 12a and the second crossbar portion 12b of the plug-side strap holding portion 11, and the crossbar portion 42 of the socket-side strap holding portion 41. That is, two or more whistle portions may be provided for a single buckle.

[0101] Example 2

[0102] Figure 12 This is a perspective view schematically representing the buckle (with mounting device) of Embodiment 2. Figures 13-17 This is a schematic diagram showing the plug portion of the buckle in this embodiment 2 from various angles.

[0103] The buckle 2 of this embodiment has a synthetic resin plug portion 60 mounted on one side of the strap body and a synthetic resin socket portion 40 mounted on the other side of the strap body. Although the socket portion 40 of this embodiment 2 is formed in a shape that is partially different from the socket portion 40 included in the buckle 1 of the aforementioned embodiment 1, it is formed in a substantially similar construction. Therefore, the socket portion 40 of this embodiment 2 is indicated by the same reference numerals as that of the aforementioned embodiment 1, and its detailed description is omitted.

[0104] In this embodiment 2, the plug portion 60 has a plug-side strap holding portion 61 for mounting and holding the strap body, and a locking portion 71 extending forward from the plug-side strap holding portion 61. The plug-side strap holding portion 61 is integrally provided with a locking portion 71 for mounting and holding the strap body. Figure 19 The guide member 85 shown is assembled inside the whistle body 81 to form the whistle part 80.

[0105] The plug-side retaining portion 61 includes: two crossbar portions 62 extending along the width direction; a pair of left and right side support portions 63 connected to the left and right ends of each crossbar portion 62; a mouthpiece portion 64 integrally disposed on one (right) side support portion 63; and two through grooves 65 formed between the left and right side support portions 63. The side support portion 63 and the mouthpiece portion 64 being integrally disposed means that a part of the side support portion 63 functions as the mouthpiece portion 64, and a part of the mouthpiece portion 64 functions as the side support portion 63, and the side support portion 63 and the mouthpiece portion 64 cooperate to perform their functions together.

[0106] The crossbar portion 62 has a first crossbar portion 62a disposed on the side near the engaging portion 71 and a second crossbar portion 62b disposed on the side away from the engaging portion 71. The strap through groove 65 has: a first strap through groove 65a disposed between the engaging portion 71 and the first crossbar portion 62a; and a second strap through groove 65b disposed between the first crossbar portion 62a and the second crossbar portion 62b. In the plug-side strap holding portion 61 of this embodiment 2, similarly to the plug-side strap holding portion 11 of the aforementioned embodiment 1, the strap body is held in a manner that allows for adjustment of the strap body length. The first crossbar portion 62a and the second crossbar portion 62b of this embodiment 2 do not have the internal space of the first crossbar portion 12a of the aforementioned embodiment 1, but are formed solidly.

[0107] The left and right side support portions 63 are formed parallel to each other along the length direction. Each of the left and right side support portions 63 has an inner edge (inner surface) 63a facing the center of the plug portion 60 in the width direction. An internal space is provided in the right side support portion 63. The left side support portion 63 is formed solidly.

[0108] The mouthpiece 64 is located above the plug 60 (when viewed from above). Figure 14When the mouthpiece 64 is formed, it is thicker than the right-side side support 63 by bulging outward in the width direction from the right-side side support 63. Furthermore, the mouthpiece 64 is located at the side of the plug portion 60 (…). Figure 15 The mouthpiece 64 is formed with a slightly reduced thickness (dimension in the thickness direction) relative to the side support portion 63 on the right side. The mouthpiece 64 extends rearward relative to the rear end of the second crossbar portion 62b. A blow-in 82 with a rearward opening is formed at the top (rear end) of the mouthpiece 64.

[0109] The side support portion 63 and the mouthpiece portion 64, which are integrally provided on the right side, are as follows: Figure 17 and Figure 18 As shown, an internal space communicating with the inlet 82 of the mouthpiece 64 is continuously provided along its length. An instrument is installed within this internal space. Figure 19 The guide member 85 is shown. A whistle outlet 83 is provided on the upper surface of the mouthpiece 64. This outlet 83 communicates with the internal space provided between the side support 63 and the mouthpiece 64.

[0110] The outlet 83 is provided with an edge portion 83a that separates airflow and an inclined surface 83b that slopes forward along the length direction from the edge portion 83a. The edge portion 83a is formed in the front end portion of the opening edge on the inner wall side of the outlet 83. The inclined surface 83b of the outlet 83 slopes forward from the edge portion 83a (see reference). Figure 17 and Figure 18 The inclined surface 83b is located at the top of the plug portion 60 ( Figure 14 The outlet 83 is located within the length direction between the front end of the first crossbar 62a and the rear end of the second crossbar 62b. Furthermore, the inclined surface 83b of the outlet 83 is formed as a plane with a certain angle of inclination relative to the length direction, extending from the edge 83a to the upper surface of the mouthpiece 64.

[0111] The whistle portion 80, which is located on the plug side with a retaining portion 61, includes: a whistle body portion 81 having an internal space; and a guide member 85 assembled to the whistle body portion 81.

[0112] In this embodiment 2, the whistle body 81 is formed into an outer frame using a portion of the right-side side support 63 and the mouthpiece 64. In this whistle body 81, the inlet 82 and outlet 83 are located on the outer side in the width direction, beyond the position of the inner edge 63a of the right-side side support 63.

[0113] Within the whistle body 81, an internal space 69 is formed along its length, continuous with the right-side side support 63 and the mouthpiece 64. This internal space 69 of the whistle body 81 provides for storage. Figure 19The guide member 85 shown has a storage space and a cavity 84 that increases the pressure of the air blown in from the inlet 82 (see reference). Figure 18 The storage space is formed along the length from the position of the inlet 82 to the rear end of the outlet 83 (the end on the side opposite to the edge 83a).

[0114] The guide member 85 of this embodiment 2 has a guide body portion 86 and a left side wall portion 87 and a right side wall portion 88 that stand out from the left and right side edges of the guide body portion 86 respectively (see reference). Figure 19 An inclined guide portion 89 is provided between the left side wall portion 87 and the right side wall portion 88. The length of this guide member 85 is the same as the length of the rear end of the whistle body portion 81 from the inlet 82 to the outlet 83.

[0115] like Figure 17 As shown, the inclined guide portion 89 of the guide member 85 has an inclined surface that slopes upward from the inlet 82 of the whistle body portion 81 toward the outlet 83 (or toward the front). The inclined surface in the inclined guide portion 89 is formed at an angle such that the edge portion 83a of the outlet 83 is located on an extension line that makes the inclined surface imaginary to be straight.

[0116] In this embodiment 2, the guide member 85 is fixed to the storage space of the whistle body 81 by adhesive or welding. Thus, the whistle part 80 of this embodiment 2 is simply formed. In addition, in this embodiment 2, similar to the case of the aforementioned embodiment 1, the molds for forming the whistle body 81 and the guide member 85 can be formed with a relatively simple structure, so the manufacturing cost of the buckle 2 can be reduced.

[0117] The cavity 84 of the whistle section 80 is formed in the portion of the internal space 69 of the whistle section 80 downstream of the edge 83a of the outlet 83 in the direction of air flow. By providing this cavity 84, as described in the aforementioned embodiment 1, when air is blown in from the inlet 82, it is possible to alternately repeat: (A) increase the pressure inside the cavity 84, and (B) discharge the air inside the cavity 84 together with the blown air from the outlet 83 to reduce the pressure inside the cavity 84, thereby enabling smooth sound production at the whistle section 80.

[0118] The engaging portion 71 of the plug portion 60 in this embodiment 2 is formed with a structure that is substantially the same as the engaging portion 21 of the plug portion 10 in the aforementioned embodiment 1. Therefore, the engaging portion 71 of this embodiment 2 will be described simply here.

[0119] In this embodiment 2, the engaging portion 71 of the plug portion 60 includes: an engaging main body 72 connected to the plug-side retaining portion 61; a pair of left and right legs 73 extending forward from the engaging main body 72; and a plug guide 74 disposed between the left and right legs 73. The engaging main body 72 has a top view of the plug portion 60 ( Figure 14 When in use, it forms a roughly V-shape. Each of the left and right legs 73 has an operating part 73a and a narrow part 73b that connects the operating part 73a to the engaging body part 72. At the top of the operating part 73a, an engaging protrusion 73c that engages with the socket part 40 protrudes upward and downward.

[0120] According to the buckle 2 of this embodiment 2, which has the plug portion 60 and the socket portion 40 described above, a whistle portion 80 is provided on the plug side of the plug portion 60 with a retaining portion 61. Therefore, air can be easily blown in from the inlet 82 provided at the rear end of the mouthpiece portion 64. In addition, sound can be easily and smoothly produced from the whistle portion 80 by using the air intake.

[0121] Furthermore, since the inlet 82 and outlet 83 of the whistle section 80 are positioned further outward in the width direction than the inner edge 63a of the support section 63, the inlet 82 and outlet 83 are also less likely to be blocked by the belt body, similar to the situation in Embodiment 1 described above. Based on this, in the buckle 2 of this Embodiment 2, the cavity 84 of the whistle section 80 is also formed using the side support 63 of the plug section 60, thus enabling miniaturization of the buckle 2 with whistle function.

[0122] Furthermore, in this embodiment 2, the whistle part 80 is provided on the right side support part 63. However, in this embodiment 2, the whistle part 80 may also be provided on the left side support part 63, or it may be provided on both the right and left side support parts 63.

[0123] Example 3

[0124] Figures 20-24 This is a schematic diagram showing the regulator (with mounting device) of this embodiment 3 from various angles.

[0125] The belt mounting device 3 of this embodiment 3 is an adjuster 3 that allows adjustment of the overall length of two belts by mounting two belts (not shown). More specifically, in the adjuster 3 of this embodiment 3, the end of one belt (e.g., the first belt) is wound and fixed to one of the crossbar portions 92, and the other belt (e.g., the second belt) is held in a state where it is wound around another crossbar portion 92 and folded back. Thus, the two belts are held in the adjuster 3 in a manner that allows their lengths to be adjusted.

[0126] The adjuster 3 of this embodiment 3 has: four crossbar portions 92; a pair of left and right side support portions 93 connected to the left and right ends of each crossbar portion 92; and a mouthpiece portion 94 protruding from one (right) side support portion 93 outward (right) in the width direction. In this case, the left and right side support portions 93 are located in the side view adjuster 3 ( Figure 22 It has: a lower end 96 that extends substantially straight along its length; and a raised portion 97 that has an upward bulging shape.

[0127] In this regulator 3, a whistle section 100 that produces sound due to the blowing of air is integrally provided using part of the shape inherent in the regulator 3. As will be discussed later, the whistle section 100... Figure 26 The guide member 105 shown is formed by assembling it inside the whistle body 101 of the regulator 3, which will be discussed later.

[0128] The crossbar portion 92 provided in the adjuster 3 has a first crossbar portion 92a, a second crossbar portion 92b, a third crossbar portion 92c, and a fourth crossbar portion 92d arranged sequentially from one end (front end) to the other end (rear end) along the length direction of the adjuster 3. The first crossbar portion 92a to the fourth crossbar portion 92d are respectively fixed to the left and right side support portions 93 by connecting to the left and right side support portions 93 at their left and right ends.

[0129] The first crossbar portion 92a is located at the front end of the adjuster 3, and is the thinnest of the four crossbar portions 92 when viewed from above. The second crossbar portion 92b is arranged rearwardly, separate from the first crossbar portion 92a. When viewed from above, the second crossbar portion 92b is thicker than the first crossbar portion 92a and thinner than the third crossbar portion 92c. A first through-slot 95a is provided between the first crossbar portion 92a and the second crossbar portion 92b.

[0130] The third crossbar portion 92c is arranged rearwardly, separate from the second crossbar portion 92b. The third crossbar portion 92c connects to the raised portions 97 (especially the upper ends of the raised portions 97) in the left and right side support portions 93, and is positioned at the uppermost of the four crossbar portions 92. A second through-slot 95b is provided between the second crossbar portion 92b and the third crossbar portion 92c.

[0131] The fourth crossbar portion 92d is disposed at the rear end of the adjuster 3. The fourth crossbar portion 92d has: a bar body portion 98 extending in the width direction; and a thin plate portion 99 integrally formed on the bar body portion 98 and extending rearward from the bar body portion 98. A third through groove 95c is provided between the third crossbar portion 92c and the fourth crossbar portion 92d.

[0132] In the third crossbar portion 92c of the regulator 3, an internal space 91 is continuously formed along the width direction, and this internal space 91 forms part of the cavity portion 104 of the whistle portion 100 (see reference). Figure 24 and Figure 25 The internal space 91 of the third crossbar portion 92c communicates with the internal space 91 of the side support portion 93 provided on the right side. The internal space 91 of the third crossbar portion 92c is continuously formed in the width direction to the position of the inner edge 93a (inner side surface) of the side support portion 93 on the left side. The first crossbar portion 92a, the second crossbar portion 92b, and the fourth crossbar portion 92d do not have internal spaces 91, but are formed solidly.

[0133] The left and right side support portions 93 are formed parallel to each other along the length direction. The left and right side support portions 93 are continuously provided from the front end of the first crossbar portion 92a to the rear end of the fourth crossbar portion 92d along the length direction. Each of the left and right side support portions 93 has an inner edge 93a (inner surface) arranged opposite to each other and an outer edge (outer surface) facing outward in the width direction. An internal space 91 is provided in the right side support portion 93.

[0134] The mouthpiece 94 protrudes outward (to the right) from the side support 93 in the width direction. This mouthpiece 94 has a shape that tapers outward in the width direction, with the tip being thinner than the base. Furthermore, the mouthpiece 94 protrudes to the right from a position corresponding to the connection point of the side support 93 with the third crossbar 92c. This allows for stable communication between the internal space 91 of the mouthpiece 94, the internal space 91 of the side support 93 on the right, and the internal space 91 of the third crossbar 92c.

[0135] An air inlet 102 is formed at the tip of the mouthpiece 94. The mouthpiece 94 and the side support 93 on the right side, as shown... Figure 25 As shown, an internal space 91 is provided along the width direction, communicating with the inlet 102 of the mouthpiece 94 and the internal space 91 of the third crossbar 92c. An internal space 91 of the mouthpiece 94 is installed within the internal space 91. Figure 26 The guide member 105 shown.

[0136] An outlet 103 is provided on the upper surface of the mouthpiece 94. The outlet 103 communicates with the internal space 91 of the mouthpiece 94 and discharges air. The outlet 103 is provided with an edge portion 103a that separates the airflow vertically and an inclined surface 103b that slopes upward along the width direction from the edge portion 103a.

[0137] The whistle portion 100 of the regulator 3 provided in this embodiment 3 has: a whistle body portion 101 having an internal space 91; and a guide member 105 assembled to the whistle body portion 101.

[0138] In this embodiment 3, the whistle body 101 is formed by a third crossbar 92c, a portion of the right-side side support 93, and a mouthpiece 94. In this whistle body 101, the aforementioned inlet 102 and outlet 103 are located further outward in the width direction than the right-side side support 93. Therefore, even when the adjuster 3 has two bands as described above, the inlet 102 and outlet 103 are less likely to be blocked by the bands.

[0139] Within the whistle body 101, an internal space 91 is formed along its width, continuous with the third crossbar portion 92c, the side support portion 93, and the mouthpiece portion 94. This internal space 91 of the whistle body 101 has a storage capacity. Figure 26 The guide member 105 shown has a storage space and a cavity 104 that increases the pressure of the air blown in from the inlet 102 (see reference). Figure 24 The storage space is formed along the width direction from the position of the inlet 102 to the end of the outlet 103 on the side opposite to the edge 103a.

[0140] The guide member 105 of this embodiment 3 includes: a guide body portion 106; a front wall portion 107 and a rear wall portion 108, which stand upright from the front end and rear end of the guide body portion 106, respectively; and an extension piece portion 110, which extends in the width direction from the guide body portion 106. An inclined guide portion 109 is provided in the guide body portion 106 and disposed between the front wall portion 107 and the rear wall portion 108. Figure 24 As shown, the inclined guide 109 has an inclined surface that slopes upward from the inlet 102 of the whistle body 101 toward the outlet 103.

[0141] In this embodiment 3, the guide member 105 is fixed to the storage space of the whistle body 101 by adhesive or fusion. Thus, the whistle part 100 of this embodiment 3 is simply formed. In addition, the mold for forming the whistle body 101 and the guide member 105 can be formed with a relatively simple structure, so the manufacturing cost of the regulator 3 can be reduced.

[0142] The cavity 104 of the whistle section 100 is formed in the portion of the internal space 91 of the whistle section 100 that is downstream of the edge 103a of the outlet 103 in the direction of airflow. By providing this cavity 104, sound can be produced smoothly at the whistle section 100 when air is blown in from the inlet 102.

[0143] In the regulator 3 of this embodiment, the whistle section 100 for producing sound can be easily installed without increasing the overall size of the regulator 3. Therefore, it is possible to achieve miniaturization of the regulator 3 that has a whistle function. In addition, in this embodiment 3, by blowing air in through the inlet 102 provided to the whistle section 100, sound can be easily and smoothly produced from the whistle section 100.

[0144] In addition, in this embodiment 3, the inlet 102 and outlet 103 of the whistle part 100 are located on the outer side of the side support part 93 in the width direction. Therefore, the inlet 102 and outlet 103 are less likely to be blocked by the belt of the regulator 3.

[0145] Furthermore, in this embodiment 3, the whistle portion 100 is formed on the third crossbar portion 92c of the regulator 3. However, in this embodiment 3, the whistle portion 100 may also be formed on any crossbar portion 92 of the regulator 3 other than the third crossbar portion 92c. Additionally, in this embodiment 3, the whistle portion 100 may be provided on two or more crossbar portions 92 of the regulator 3.

[0146] Furthermore, in the aforementioned embodiment 1 and embodiment 3, the air outlets 33, 83, and 103 are located on the upper surface of the whistle body portions 31, 81, and 101, which form the outer frame. However, in this invention, the location of the outlet is not particularly limited; the outlet can also be located on, for example, the lower surface of the whistle body portion, the front side wall portion, or the rear side wall portion. In, for example, in embodiment 1, even if the outlet is located on the lower surface of the whistle body portion, it is difficult for the outlet to be blocked by the belt.

[0147] Furthermore, in the aforementioned embodiments 1 to 3, the outlets 33, 83, and 103 of the whistle portions 30, 80, and 100, when viewed from above with the belt mounting fixtures 1 to 3, are located on the outer side in the width direction, relative to the inner edges 13a, 63a, and 93a of the left and right side support portions 13, 63, and 93. However, in this invention, the outlets of the whistle portions may also be located on the inner side in the width direction, relative to the inner edges of the left and right side support portions. For example, in the belt mounting fixture of embodiment 1, the outlet of the whistle portion may also be located on the lower surface of the first crossbar portion 12a, which is positioned on the inner side of the inner edge 13a of the right side support portion 13. In this case, although the belt wound around the first crossbar 12a and folded back covers the upper surface of the first crossbar 12a, the lower surface of the first crossbar 12a is difficult to be directly covered by the two belt portions folded back at the first crossbar 12a. Therefore, the outlet provided to the lower surface of the first crossbar 12a is less likely to be blocked by the belt.

[0148] Furthermore, in the aforementioned embodiments 1 to 3, the openings of the whistle portions 30, 80, and 100 are provided with two types of openings: blow-in inlets 32, 82, and 102, and exhaust outlets 33, 83, and 103. However, in this invention, as long as the air pressure can be appropriately increased within the cavity of the whistle portion, openings (holes) other than blow-in inlets and exhaust outlets can be provided in the whistle portion. For example, in this invention, to facilitate the molding of the whistle portion using a mold, an opening may be formed in a part of the whistle portion in a manner communicating with the internal space, allowing a part of the mold to pass through.

[0149] Furthermore, in the aforementioned embodiments 1 to 3, the whistle portions 30, 80, and 100 are inseparably provided to the buckles 1 and 2 or the adjuster 3. However, in the belt mounting device of the present invention, the portion including the whistle portion that produces sound can also be provided to the belt mounting device in a manner that allows it to be detached from the belt mounting device. As an example of such a belt mounting device, there exists a belt mounting device in which the portion including the whistle portion is detachably mounted by a snap button.

[0150] Furthermore, in the aforementioned Embodiments 1 to 3, the whistle portions 30, 80, and 100 are formed by fixing guide members 35, 85, and 105 to the whistle body portions 31, 81, and 101, which form the outer frame portions. However, in this invention, the whistle portion provided with the mounting device may, for example, be formed by assembling a first component (e.g., the portion of the whistle portion in Embodiment 1 excluding the upper surface portion) integrally formed with guide members with a second component (the upper surface portion of the whistle portion in Embodiment 1) formed from the portion of the whistle portion excluding the first component with each other. Moreover, the whistle portion provided with the mounting device may also have a structure formed by combining three or more components.

[0151] Furthermore, in the mounting device of the present invention, the cavity portion for increasing air pressure can be provided in at least a portion of the crossbar portion and a pair of side support portions. That is, the cavity portion can be provided in a portion or all of the crossbar portion, a portion or all of the side support portions, or a portion or all of both the crossbar portion and the side support portions.
