Description

Technical Field

[0001] This invention relates to a back clip, specifically a firefighter distress call back clip, belonging to the field of fire equipment technology. Background Technology

[0002] A distress call device is essential equipment for firefighters. Most distress call devices currently use a fixed, vertical clip. For communication-type distress call devices, they are typically clipped to a loop slightly below and forward of the firefighter's shoulder. The antenna of the distress call device should be as high as possible above the shoulder to facilitate wireless signal transmission. When a firefighter is wearing a self-contained breathing apparatus (SCBA), the SCBA straps obstruct the original clipping position. In this case, the firefighter will clip the distress call device onto the SCBA straps.

[0003] Because the breathing apparatus straps are vertical, while the distress call clips cannot be turned, the distress call can only be held horizontally on the breathing apparatus straps. This causes the distress call antenna to point horizontally outward from the firefighter, changing the antenna's radiation direction and affecting communication performance. In some cases, it can even affect the normal operation of certain types of vibration sensors in the distress call. In addition, the antenna, which is horizontally on the outside of the firefighter's body, is also prone to being snagged or bumped during firefighting operations, causing the antenna mount to break. This results in the distress call losing its waterproof, explosion-proof, and communication functions, or even damaging the entire device. Summary of the Invention

[0004] The purpose of this invention is to provide a rotatable and lockable distress call clip, allowing the angle between the clip's clamping direction and the direction of the distress call it carries to be adjusted and locked. For example, rotating the clip ±90° allows it to be horizontally clipped onto a vertical self-contained breathing apparatus strap, while the distress call itself remains vertical and parallel to the strap, thus ensuring the distress call's antenna remains vertical. Similarly, for certain applications, the clip can be adjusted to other suitable angles and locked for better clamping onto the target object, while maintaining the distress call itself and its antenna in a vertical position.

[0005] The present invention adopts the following technical solution:

[0006] A distress call back clip includes an upper clip 2, a lower clip 3, and a pressure cover 1. The upper clip 2 can be placed on the lower clip 3 and is pressed and positioned by the pressure cover 1, which is hinged to the lower clip 3. The clip is characterized by further including a positioning disc 4, on which a plurality of recessed holes 401 are evenly distributed around its perimeter. The positioning disc 4 is fitted to the lower clip 3 and is rotatably connected by a pressure pin 5. A through hole 301 is provided at the upward-curved edge of the lower clip 3. The upper clip 2 has a hole at its tail that can pass through the through hole 301 and connect with the lower clip 3. The protrusion 201, which engages with the recessed hole 401, serves to lock the position between the upper clamping plate 2 and the positioning plate 4. The bottom surface of the lower clamping plate 3 is provided with a pair of positioning protrusions 303 symmetrically distributed around the center of the pressure nail 5. The upper periphery of the positioning plate 4 is evenly distributed with grooves 402 corresponding to the recessed holes 401. The protrusions 303 engage with the grooves 402 to lock the position between the lower clamping plate 3 and the positioning plate 4. The exposed surface of the positioning plate 4 is used for fixed connection with the emergency call device.

[0007] Preferably, the contact point of the head of the boss 201 is arc-shaped, which facilitates sliding into and out of the recess 401 and sliding on the positioning disk 4.

[0008] Furthermore, the recess 401 is in the shape of an arc surface, which facilitates the sliding of the contact part into and out of it.

[0009] Furthermore, the contact point of the head of the protrusion 303 is arc-shaped, and the groove 402 on the positioning disk 4 is correspondingly arc-shaped, which facilitates the protrusion 303 to slide in and out.

[0010] Preferably, the lower clamping plate 3 has a pair of upwardly flipped ear plates 302 on both sides and an upwardly flipped tail plate 304 at the tail end, forming a pair of gaps between the ear plates 302 and the tail plate 304; the upper clamping plate 2 has a pair of protrusions 203 extending to both sides on both sides, the protrusions 203 being confined within the gaps, thus limiting the planar relative movement between the upper clamping plate 2 and the lower clamping plate 3; the ear plates 302 also provide a connecting part that is hinged to the pressure cover 1.

[0011] Furthermore, the pressure cap 1 is L-shaped, with one end being a flip-top portion and the other end being a force-applying portion 101 that applies planar pressing force to the upper clamping plate 2.

[0012] A distress call device, comprising the distress call device back clip described in any one of the above.

[0013] Preferably, the distress call device is used by fire and rescue personnel.

[0014] Furthermore, when the distress caller is used simultaneously with the air respirator, the angle of the upper clamp 2 and the lower clamp 3 relative to the positioning plate 4 is adjusted so that the antenna of the distress caller faces upward. The serrations of the upper clamp 2 and the lower clamp 3 of the distress caller back clip are separated and laterally engaged on the air respirator strap. The pressure cover 1 is pressed down to lock the angle of the back clip and tighten it on the air respirator strap.

[0015] The beneficial effects of this invention are as follows: It provides a distress call back clip, which allows the angle between the clip's clamping direction and the direction of the distress call it carries to be adjusted and locked, so as to adapt to combat scenarios where it is used simultaneously with equipment such as air respirators, thereby better completing firefighting missions. In particular, for example, when the clip is clamped onto the vertical air respirator strap, it still ensures that the distress call is in a vertical position, so that the antenna of the distress call is in a vertical state and is as high as possible above the shoulder, thereby obtaining better communication effect. In addition, the fact that the antenna does not protrude from the side of the body also reduces the risk of the antenna being snagged or collided with, which could lead to corresponding malfunctions of the distress call.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See Figures 1-7A distress call back clip includes an upper clip 2, a lower clip 3, and a pressure cover 1. The upper clip 2 can be placed on the lower clip 3 and is pressed and positioned by the pressure cover 1, which is hinged to the lower clip 3. The clip is characterized by further including a positioning disc 4, on which a plurality of recessed holes 401 are evenly distributed around its perimeter. The positioning disc 4 is fitted to the lower clip 3 and is rotatably connected by a pressure pin 5. A through hole 301 is provided at the upward-curved edge of the lower clip 3. The upper clip 2 has a hole at its tail that can pass through the through hole 301 and connect with the lower clip 3. The protrusion 201, which engages with the recessed hole 401, serves to lock the position between the upper clamping plate 2 and the positioning plate 4. The bottom surface of the lower clamping plate 3 is provided with a pair of positioning protrusions 303 symmetrically distributed around the center of the pressure nail 5. The upper periphery of the positioning plate 4 is evenly distributed with grooves 402 corresponding to the recessed holes 401. The protrusions 303 engage with the grooves 402 to lock the position between the lower clamping plate 3 and the positioning plate 4. The exposed surface of the positioning plate 4 is used for fixed connection with the emergency call device.

[0026] In this embodiment, combined with Figure 2 , 4 7. The contact point of the head of the boss 201 is arc-shaped, which facilitates sliding into and out of the recess 401 on the positioning plate 4 and sliding on the surface of the positioning plate.

[0027] In this embodiment, see Figure 4 The recessed hole 401 is in the shape of an arc surface, which facilitates the sliding of the contact part into and out of it.

[0028] In this embodiment, see Figure 4 and 6 The contact point of the head of the protrusion 303 is arc-shaped, and the groove 402 on the positioning disk 4 is correspondingly arc-shaped, which facilitates the sliding of the protrusion 303 into and out.

[0029] In this embodiment, see Figure 5-6 The lower clamping plate 3 has a pair of upward-curving ear plates 302 on both sides and an upward-curving tail plate 304 at the tail end, forming a pair of gaps between the ear plates 302 and the tail plate 304; see also Figure 7 The upper clamping plate 2 has a pair of protrusions 203 extending to both sides. The protrusions 203 are confined within the space, thus limiting the planar relative movement between the upper clamping plate 2 and the lower clamping plate 3 (e.g., Figure 3 See also Figure 2-3 The ear plate 302 also provides a connection part that is hinged to the cover 1, so the ear plate 302 actually achieves two purposes at once.

[0030] See Figure 2-3 The pressure cap 1 is L-shaped, with one end being a flip-top and the other end being a force-applying part 101 that applies planar pressure to the upper clamping plate 2.

[0031] A distress call device includes the aforementioned distress call device back clip. The distress call device is used by firefighters.

[0032] In a preferred embodiment, the distress caller is used simultaneously with the air respirator. The angle of the upper clamp 2 and the lower clamp 3 relative to the positioning plate 4 is adjusted so that the antenna of the distress caller faces upward. The serrations of the upper clamp 2 and the lower clamp 3 of the distress caller back clip are separated and laterally engaged on the air respirator strap. The pressure cover 1 is pressed down to lock the angle of the back clip and tighten it on the air respirator strap.

[0033] See Figure 3 Regarding the pressure nail 5 and the positioning plate 4, the following supplementary explanation is provided:

[0034] The pressure pin 5 mainly includes a screw, and one of the following two options can be selected:

[0035] 1) Place a spring or spring sheet under the screw so that when the cover 1 is opened and the cover 1, upper clamping plate 2, and lower clamping plate 3 are rotated, the protrusion 303 and the groove 402 switch between overlapping and not overlapping, so that there is a clear gear feel when rotating, making it easy to rotate to the accurate gear.

[0036] 2) No spring is placed under the screw. The screw is equivalent to a rotating shaft. There is an appropriate gap between the lower clamping plate 3 and the positioning plate 4. When the protrusion 303 and the groove 402 overlap, it indicates that the gear is in position. When rotating the cover 1, the upper clamping plate 2, and the lower clamping plate 3, the protrusion 303 is squeezed out from the groove 402 and pressed on the plane of the positioning plate. It has a certain tension due to the elastic deformation of the lower clamping plate 3 itself. When rotating to another groove, the protrusion enters the groove, producing the feeling of entering the gear.

[0037] The first method uses springs or spring sheets, which increases the number of parts, but its advantage is that it does not have high requirements for installation clearance.

[0038] The second method utilizes the elastic deformation of the lower clamping plate 3 to generate the gear shift feel. An appropriate gap needs to be maintained between the lower clamping plate 3 and the positioning plate 4 to ensure normal operation. If the gap is too large, it will be too loose, resulting in an indistinct feel, or even free rotation without a gear shift feel. If the gap is too small, the protrusion 303 and the groove 402 may be in too tight contact, making rotation difficult. The material of the lower clamping plate 3 also needs to have a certain degree of elasticity.

[0039] The concave hole 401 and the groove 402 can be combined into a slot 402 to simplify the process, such as by directly stamping it on the positioning plate 4.

[0040] The protruding strip 303 can be stamped on the lower clamping plate 3, which is convenient for processing.

[0041] When the pressure cap 1 is not pressed to lock, the back clip has a gear feel when rotating, which is a weak lock. At this time, it can be turned and the angle can be adjusted. Pressing the pressure cap 1 will simultaneously make the serrations bite and lock the gear.

[0042] In summary, this embodiment details a firefighter distress call back clip that can be rotated and locked in multiple directions. The back clip can adjust its turning angle and lock according to the direction of the target being clipped, so that the distress call body and antenna are in a vertical working state, and the antenna is kept as high as possible above the firefighter's shoulder to achieve better wireless transmission effect. At the same time, the fact that the antenna does not extend from the side of the human body also reduces the related hazards caused by the antenna being hooked or collided.

[0043] The above are preferred embodiments of the present invention. Those skilled in the art can make their own modifications or improvements based on this, and such modifications or improvements should fall within the scope of protection claimed by the present invention without departing from the overall concept of the present invention.
