Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the invention  
         [0002]     The present invention relates to a safety belt device, and more particularly to a safety belt device having a warning device for generating signals automatically when accidents happened.  
         [0003]     2. Description of the Prior Art  
         [0004]     For protecting workers who are working at high elevations or buildings or architectures, safety nets will be attached to the lower portion of the buildings or architectures, for supporting the workers fell from the buildings or architectures, and for preventing the workers from directly fell down to the ground.  
         [0005]     In addition to the safety nets, various kinds of safety belts have also been developed to be hooked or secured between the workers and the buildings or architectures, to suspend the workers and to prevent the workers from directly fell down to the ground when accidents happened.  
         [0006]     Normally, the typically safety belts comprise two hooks or latches attached to the end thereof, for hooking or securing to the workers and the buildings or architectures respectively, and to suspend and space the workers from the ground when the workers fell out of the buildings or architectures inadvertently. However, in some of the accidents, when the workers fell out of the buildings or architectures and suspended at high levels by the safety belts, the workers may be unconscious and may not ask help from others.  
         [0007]     The U.S. Pat. No. 4,253,544 discloses a safety belt device having warning device, it comprises a warning device having a flag deposited in a box, when accident happens, the flag will automatically stream in the air so as to attract the attention of people, and attain the effect of warning. However, the skill of using the flag to be streamed in the air can not be inspected by people all the time, especially when the sky is dark.  
         [0008]     The Japanese patent publication JP10-277172 discloses a safety belt device having warning device, it comprises a warning device capable of delivering warning sound, the warning device contains an insulating plate to be inserted between two batteries, the other end of the insulating plate connected to a pulling rope. When accident happens, the pulling rope will pull the insulating plate out of the position between two batteries and then the warning device is conducted. However this kind of safety belt device has the disadvantages that is the insulating plate is easy to fall down and causes unnecessary alarm.  
         [0009]     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional safety belts.  
       SUMMARY OF THE INVENTION  
       [0010]     The main object of the present invention is to provide a safety belt device having a warning device for generating signals automatically when accidents happened, so as to obtain the first time of saving the worker&#39;s life.  
         [0011]     Another object of the present invention is to provide a safety belt device having warning device, it contains a buffer belt and a actuator pin for actuating the warning device to deliver warning signal; wherein, the initiator pin has one end to be inserted to the ON/OFF switch of warning device, and another end to be connected to a pulling rope with designated length, another end of said pulling rope is then connected to the end surface of said buffer belt. Thus, when accident happens, since the user is falling downward, due to the pulling force, the buffer belt then extended one face by another face, said actuator pin then is pulled out of the warning device, and the warning device is actuated, so that the function of automatically delivering warning signal on the time when accidents happened is achieved.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0017]     Refer to the drawings, the initially to  FIG. 1  and  FIG. 2 , a safety belt device in accordance with the present invention is generally indicated with a reference numeral “ 1 ” and comprises a belt body  10  including a fastener member  12 , such as a latch or hook provided on one end for attaching to the worker  80  ( FIG. 1 ), and another fastener member  14  provided on the other end for attaching to supporting members, such as the buildings or architectures, etc. (not shown).  
         [0018]     The fastener members  12 ,  14  may be hooked or attached to the supporting members for suspending the worker  80  from the ground or for preventing the worker  80  from directly fell down to the ground when accident is happened.  
         [0019]     A clamp portion  18  provided onto the surface of belt body  10 , it is connected with the belt body  10  by its outer edges so that a space is formed inside the clamp portion, and there is a hole  181  formed on the surface of clamp portion  18 .  
         [0020]     Please also refer to  FIG. 3 , there is a buffer belt  20  made of nylon or plastics, it has a plurality of buffer units  20   a .  20   b .  20   c  . . .  20   z , the buffer units  20   a .  20   b .  20   c  . . .  20   z  are connected each others firstly and are bent each others, then finally, sawed together to formed a whole body of buffer device so that when the buffer device is pulled, it will be extended and peeled one piece by another, thus obtain a long extended buffer device  20 . Wherein, the first buffer unit  20   a  is connected to one end  16  of belt body  10 , the last buffer unit  20   z  is connected to one end of fastener members  12 .  
         [0021]     A warning device  30  is capable of generating warning signals to ask help from others when accidents happened. It is composed of a body  31  and a cover  32 . On the body  31 , there are a set of LED alarm lamps  33  and a buzzer  34 , said cover  32  is made of light-penetrated materials. There is a switch  35  formed on one side of the body  31 , there is also a rocket  36  formed on its bottom, said rocket  36  is provided for insertion of metallic actuator pin  37 , while the another end of the actuator pin  37  is connected to a pulling rope  38 , another end of pulling rope  38  is then connected to the surface of the last buffer unit  20   z ; And, there is a clip board  39  provided on the back of the body  31 , so that the warning device  30  can be inserted into the hole  181  on the clamp portion  18  and then fixed onto the belt body  10 .  
         [0022]     The actuator pin  37  of the warning device  30  is arranged to actuated or operated when the buffer device  20  is extended or stretched.  
         [0023]     In using the present invention, as shown in  FIG. 4 , the fastener member  12  near the buffer device  20  is provided for attaching to the worker  80  ( FIG. 1 ), another fastener member  14  provided on the other end for attaching to the supporting members, such as the buildings or architectures.  
         [0024]     At this moment, one end of the metallic actuator pin  37  connects to the pulling rope  38 , and its another end is inserted into the rocket  36  formed at the bottom of the warning device  30 , because the warning device is in “OFF” state, it would not deliver alarm signals; when accident happens, and the worker is falling down, as shown in  FIG. 5 , the buffer units  20   a .  20   b . 20   c  . . .  20   z  of buffer device  20  shall be peeled one piece after another due to the falling gravity of worker. When the first buffer unit  20   a  is peeled off from the buffer device  20 , due to the fixed length of pulling rope  38 , and due to one end of the pulling rope  38  is fixed to the last buffer unit  20   z , the metallic actuator pin  37  shall be pulled downward by the pulling rope  38 , and separates away from the rocket  36 . Then the ON/OFF switch of warning device  30  is positioned at the ON state. The alarm signal then is delivered to ask for help to people around the building.  
         [0025]     Accordingly, the safety belt device in accordance with the present invention includes a warning device for automatically generating warning signals to ask help from others when accidents happened.  
         [0026]     Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
