Description

Technical Field

[0001] This invention relates to a strap buckle, and in particular, a pressure-relief strap buckle that improves the structure by minimizing pressure on the skin or contact area while performing the functions of adjusting and securing the strap length. Background Technology

[0002] Generally, hats, clothing, bags, protective equipment, and various wearable devices widely employ buckle structures that utilize straps to maintain the wear or adjust the length. These strap buckles perform the following functions: securing the strap in a certain position or adjusting the length as needed.

[0003] As a related technology for such a clasp or an article with a clasp, Korean Patent Registration No. 10-1984907 (registered on May 27, 2019, hereinafter referred to as "Document 1") discloses a "hat with a tightening means".

[0004] The hat disclosed in Document 1 includes a crown portion that covers the wearer's head and a brim that is attached to the lower edge of the crown portion and positioned on the upper part of the wearer's face. It also includes a tightening means for adjusting the size of the crown portion. The tightening means includes: a loop portion located at one end of a semi-circular opening on the back of the crown portion, with a through hole formed in the center; a strap portion, one end of which is fixed to the other end of the opening portion, and the other end extending through the through hole towards the other side of the opening portion; and a tightening device provided along the lower edge of the crown portion, wherein a steel wire, one end of which is connected to the other end of the strap portion, is internally wound and connected, and a tensile force is applied to the steel wire by rotation to pull the strap portion. Thus, the tightening means is easy to adjust in size and improves aesthetics.

[0005] However, most existing fasteners, such as those in Reference 1, have protruding lower surfaces or complex internal structures that directly compress the wearer's skin or contact areas. In particular, the discomfort caused by pressure can be exacerbated during prolonged wear, and in some cases, it can even induce pain or skin damage.

[0006] Furthermore, the separation of the adjustment strap structure from the fixing structure, or the inconvenience of operation, reduces the user's convenience.

[0007] Therefore, there has been a continuous demand for a new type of buckle that can stably secure the buckle while minimizing pressure during wear and is easy to operate.

[0010] (Patent Document 1) Korean Patent Registration No. 10-1984907 (Registered on May 27, 2019) Summary of the Invention

[0011] The purpose of this invention is to provide a pressure-reducing buckle that improves wearing comfort by minimizing pressure on the lower part of the buckle while stably securing the strap.

[0012] Furthermore, the purpose of this invention is to provide an anti-compression type hook-and-loop fastener that effectively pulls the strap as the fastener moves along the strap, thereby improving ease of operation.

[0013] To address the aforementioned issues, the present invention provides an anti-pressure type cable tie buckle comprising: a buckle body having an upward opening for receiving a portion of the cable tie; a clamping member for securing and releasing the secured portion of the cable tie received in the buckle body; and a puller for pulling the cable tie as the buckle body moves along the cable tie.

[0014] In the pressure-relieving buckle of the present invention, the lower surface of the buckle body is implemented with a non-protruding structure. In particular, the strap is configured to be positioned on the upper side of the buckle body rather than on the lower side, thereby minimizing any potential step difference between the buckle body and the strap. As a result, the buckle and strap are flatter overall and form an almost aligned arrangement, significantly reducing the phenomenon of localized pressure on the skin or contact areas during wear.

[0015] Furthermore, the serrated clamping heads formed on the clamping member can more stably press and secure a portion of the strap housed within the hook and loop body, thus effectively preventing the strap from shifting or loosening. At the same time, the strap can be effectively pulled by the puller, allowing the user to adjust the strap length more easily and quickly.

[0016] Furthermore, the ramp structure formed on the front and rear ends of the upper part of the hook and loop body allows the strap to move more smoothly, thus reducing jamming or frictional resistance during length adjustment and improving ease of use.

[0017] Furthermore, the ramp structure can mitigate the step difference between a portion of the strap housed within the buckle body and a portion of the strap detached from the buckle body, thus guiding overall flattening and preventing or minimizing the occurrence of pressure marks on the skin or contact areas during wear.

[0028] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] It should be noted that the interpretations of terms or vocabulary used in this specification and claims are not limited to their ordinary or dictionary meanings. The inventors may appropriately define the concepts of relevant terms in order to best explain their invention. Based on this principle, they should be interpreted according to their meanings and concepts consistent with the technical spirit of this invention. Therefore, the embodiments described in this specification and the structures shown in the accompanying drawings are merely embodiments of the invention and do not encompass all the technical spirit of the invention. Various equivalents and modifications may exist at the time of the patent application for this invention.

[0030] by Figure 1 Based on this, the directions are defined as follows: the hinge rod side of the pulling member is the front or front part, and the pulling rod side of the pulling member is the rear or rear part.

[0031] like Figures 1 to 8As shown, the pressure-relieving buckle of the present invention includes:

[0032] The buckle body 10 has an opening at the top and accommodates a portion of the strap 1.

[0033] Clamping member 20 is used to secure and release a portion of the strap 1 housed in the buckle body 10; and,

[0034] Puller 30, used to pull the strap 1 when the buckle body 10 moves along the strap 1.

[0035] At this time, the lower surface of the buckle body 10 is implemented with a non-protruding structure.

[0036] Furthermore, the buckle body 10 has a pair of pillars 12 that stand upright at the left and right ends and each has a hinge hole 11, and the clamping member 20 has a pair of side plates 22 that bend downward at the left and right ends and each has a corresponding hinge hole 21 corresponding to the hinge hole 11.

[0037] Furthermore, the puller 30 is implemented as a bar structure with a circular cross-section, including: a pair of hinged rods 31, which pass through the hinge holes 11 of each column 12 and are clamped into the corresponding hinge holes 21 of each side plate 22 and then rotate; and a pull rod 32, which connects the hinged rods 31 to each other and is combined with the end of the strap 1.

[0038] Furthermore, the clamping member 20 is formed with a serrated clamping head 23. When the clamping member 20 is closed with reference to each hinge rod 31, the serrated clamping head 23 pressurizes and fixes a portion of the strap 1 housed in the buckle body 10.

[0039] Furthermore, a slope 13 inclined in the front and rear directions is formed on the front and rear end sides of the upper surface of the buckle body 10.

[0040] More specifically, the present invention discloses an anti-pressure type strap buckle as a buckle structure for performing the length adjustment and fixing functions of the strap 1. It improves the configuration structure of the strap 1 and the shape of the lower part of the buckle to minimize local pressure during wearing, while ensuring ease of operation and fixing stability.

[0041] as Figures 1 to 5The hook and loop body 10 is the skeleton of the overall hook and loop structure, providing space for a portion of the area to accommodate the strap 1. The hook and loop body 10 is formed with an open top, so that the strap 1 is accommodated for a certain length after being inserted into the interior from the top side of the hook and loop body 10. The interior of the hook and loop body 10 has a receiving portion for accommodating the strap 1, which is formed in a manner corresponding to the width and thickness of the strap 1 to suppress excessive swaying or twisting of the strap 1 in the left and right directions.

[0042] The bottom surface of the receiving portion is a support surface that performs the same function as the upper surface of the buckle body 10, serving as a reference surface that provides a reaction force when the strap 1 is pressed by the clamp 20. The support surface is formed relatively flat, but preferably, it is formed in a manner that is not excessively rough or has sharp corners to avoid damage to the material of the strap 1 (e.g., fabric, synthetic fiber, leather, etc.).

[0043] Especially, like Figure 4 and Figure 5 The lower surface of the buckle body 10 is formed with a non-protruding structure. That is, the lower surface does not form any additional downward-protruding support protrusions, locking parts, shaft support parts, or fastening structures, and is implemented with an overall flat or gently curved surface shape. The lower surface is the surface that directly contacts the user's skin or the object being worn, so preferably, in order to prevent pressure from accumulating locally, the corners are rounded or formed with a curved transition structure.

[0044] Furthermore, like Figure 6 In this invention, the strap 1 is configured such that it does not pass under the buckle body 10 but is positioned in the upper receiving portion. Therefore, instead of an overlapping structure between the buckle body 10 and the strap 1, they are arranged in a single row on the same plane. This configuration minimizes the height difference between the buckle body 10 and the strap 1, thus minimizing the step difference and maintaining a thin and flat overall shape. Consequently, it reduces pressure on specific areas during wear, effectively suppressing pressure marks or pain even after prolonged wear.

[0045] Each post 12 is formed vertically upwards at the left and right ends of the latch body 10. The post 12 extends upwards from the side of the latch body 10, providing support for the rotatable engagement of the clamping member 20 and the pulling member 30. Each post 12 has a hinge hole 11, which is formed on the same axis in the left-right direction. The hinge hole 11 has a circular or equivalent cross-section, and after the hinge rod 31 (described later) is inserted, it acts as a rotation axis.

[0046] Moreover, like Figure 7The upper front and rear ends of the hook-and-loop body 10 are formed with ramps 13 that slope in the rearward direction. These ramps 13 prevent the strap 1 from getting stuck or folding due to abrupt changes in height when it enters or leaves the receiving portion of the hook-and-loop body 10. In other words, the ramps 13 form a gently sloping surface that is continuous with the direction of travel of the strap 1, guiding the strap 1 to flow in and out naturally. This reduces frictional resistance when the strap 1 moves, reduces wear on the strap 1 during repeated length adjustments, and improves the feel of operation.

[0047] Then, as Figures 1 to 5 The clamping member 20 performs the function of selectively pressurizing and securing a portion of the strap 1 housed in the hook and loop body 10 or releasing the pressurized and secured state. The clamping member 20 includes a body portion extending in the front-rear direction, which is the part that the user can directly operate by hand, and is formed in a manner with appropriate thickness and rigidity.

[0048] The left and right ends of the clamping member 20 are formed with downwardly bent side plates 22, and the lower end or lower side of the side plates 22 is formed with corresponding hinge holes 21. The corresponding hinge holes 21 and the hinge holes 11 of the column portion 12 are formed on the same axis, and the hinge rod 31 passes through both the hinge holes 11 and the corresponding hinge holes 21. Therefore, the clamping member 20 is engaged in a manner that allows it to rotate relative to the buckle body 10.

[0049] as Figure 5 and Figure 6 The clamping member 20 has a clamping head 23 formed on its lower side for pressurizing and fixing the strap 1. The clamping head 23 is serrated. The serration is a structure in which multiple teeth are continuously formed. When the clamping member 20 performs the closing action, it contacts the surface of the strap 1 to prevent slippage. The teeth and the surface of the strap 1 partially mesh, simultaneously exerting friction and mechanical locking effects, thereby ensuring a high fixing force with a relatively small amount of applied pressure.

[0050] The tooth angle, spacing and height of the clamping head 23 can be appropriately set according to the material and thickness of the strap 1. Preferably, it is designed in a way that can prevent damage to the strap 1 and ensure sufficient fixing force.

[0051] Then, as Figures 1 to 5 The pull member 30 is an element that moves the position of the buckle body 10 by pulling the strap 1. It is implemented by a rod structure with a circular cross section, which includes a pair of hinged rods 31 and a pull rod 32 connecting the hinged rods 31.

[0052] Each hinge rod 31 is rotatably engaged by passing through the hinge hole 11 of the column portion 12 and clamping into the corresponding hinge hole 21 of the side plate 22. In this way, the hinge rod 31 functions as a rotation axis of the clamping member 20 while also serving as part of the structure of the pulling member 30. This structure achieves rotatable engagement without the need for additional pivot pins, thus reducing the number of parts and simplifying the structure.

[0053] With the end of the strap 1 engaged with the pull rod 32, if the user pulls the clamp 20, the strap 1 is pulled and the buckle body 10 moves along the strap 1. During this process, the ramp 13 smoothly guides the strap 1 to move, reducing friction and allowing for gentle length adjustment.

[0054] The operation process of this invention will be described in detail below.

[0055] In the initial state, the clamping member 20 remains closed and the clamping head 23 presses down on the strap 1 to secure it. In this state, the strap 1 will not move due to external force, thus maintaining the set length.

[0056] When the user wants to adjust the length of the strap 1, they lift the clamp 20 to release the pressure. This allows the strap 1 to move freely within the buckle body 10.

[0057] Then, when the user pulls the clamp 20, the puller 30, which is pulled together with the clamp 20, pulls the strap 1, causing the position of the buckle body 10 to move, thereby adjusting the length of the strap 1.

[0058] After the length adjustment is completed, if the clamping member 20 is closed again, the clamping head 23 will press the strap 1 again to form a fixed state.

[0059] Therefore, in terms of structure, the lower surface of the hook and loop body 10 is formed in a non-protruding shape, realizing a row-like structure with the strap 1 arranged on the upper side, thereby minimizing the step difference between the hook and loop and the strap. Moreover, the ramp 13 allows the strap to move smoothly, and the serrated clamping head 23 achieves stable fixation.

[0060] On the other hand, like Figure 8 The strap 1 is located at the rear of the hat body 2 for adjusting the perimeter of the hat. One end is fixed to one side of the rear of the hat body 2, while the other end is movable and supported on the other side of the rear.

[0061] The other end of the strap 1 is configured to pass through the buckle body 10 in a state where it is arranged along the upper part of the buckle body 10, and is pulled by the puller 30 to adjust the perimeter length of the hat.

[0062] The hat body 2 may be a hat in the shape of a general baseball cap, having a length corresponding to or greater than the perimeter of the wearer's head. The strap 1 is configured to cross the rear opening area of ​​the hat body 2 so that its length can be adjusted according to the perimeter of the wearer's head.

[0063] One end of the drawstring 1 is fixed to the rear side of the hat body 2. The fixing can be achieved by sewing, riveting, heat welding or other known fixing methods. Preferably, one end of the drawstring 1 is firmly fixed so that it cannot move relative to the hat body 2.

[0064] On the other hand, the other end of the strap 1 is configured such that it is movable and supported on the other side of the rear of the hat body 2. Here, "movably supported" does not mean that the other end of the strap 1 is completely fixed to the hat body 2, but rather that it is configured to move in the longitudinal direction via the buckle structure. For this purpose, the other end of the strap 1 extends in a free-end form at or near the other side of the rear of the hat body 2, and can move along a path controlled by the buckle body 10 and the pull member 30.

[0065] The other end of the strap 1 is configured to pass through the hook and loop body 10. Specifically, the path is such that the other end of the strap 1 enters the internal receiving space through the upper opening of the hook and loop body 10 and is arranged according to a certain length, and is led out to the front or rear side of the hook and loop body 10. At this time, the strap 1 does not enter the lower side of the hook and loop body 10 but is arranged along the upper side, which is one of its features. In this way, a row arrangement structure is formed in which the strap 1 and the hook and loop body 10 are actually arranged on the same plane.

[0066] With the configuration structure described above, it is possible to prevent the strap 1 from overlapping in thickness and forming step differences that might occur when passing under the buckle body 10, resulting in a thinner overall buckle that remains flat. In particular, when the buckle contacts the back of the head or scalp while wearing a hat, it can also suppress the phenomenon of specific areas being pressed by protruding structures, thereby significantly reducing the wearer's discomfort and pressure.

[0067] The other end of the strap 1 is also attached to the puller 30. This attachment can be achieved by wrapping the end of the strap 1 around the puller 32 or by sewing it in place, so that the other end of the strap 1 moves together when the puller 30 is operated.

[0068] When the user needs to adjust the perimeter length of the hat, after lifting the clamp 20 to release the pressure applied by the clamp head 23, the user can adjust the length of the strap 1 while moving the buckle along the strap 1, and the perimeter length of the hat body 2 will gradually decrease or increase.

[0069] After the length adjustment is completed, if the clamping member 20 is rotated in the direction of closing again, the clamping head 23 presses the strap 1 to form a fixed state, stably maintaining the perimeter length of the adjusted hat.

[0070] In particular, in the structure of the present invention, the straps 1 are arranged in a row on the upper side of the buckle body 10, and the lower surface of the buckle body 10 is implemented with a non-protruding structure, so that the contact surface remains flat even when the buckle is close to the scalp when wearing the hat. Therefore, the contact pressure is not concentrated in a local area but is distributed over a large area, effectively preventing pressure marks or pain even when worn for a long time.

[0071] Therefore, when applied to the perimeter adjustment structure of a hat, this invention not only achieves a simple length adjustment function, but also significantly improves wearing convenience and user satisfaction.

[0072] In describing the present invention, the drawings were mainly used to illustrate the pressure-relieving buckle with a specific shape and structure.
