Abstract:
The present invention pertains to an assemblage of sealing nail essentially containing a nail, a propeller, and a blocker that is partially extended beyond the propeller. Wherein, the nail would sequentially penetrate the propeller, the blocker, and then a plank. By means of the nail entering the plank, the propeller and the blocker would be simultaneously urged to densely cover up where the nail inserted. Therefore, a preferred sealing efficiency between the nail and the plank is achieved to guarantee a favorable grouting on the plank.

BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an assemblage, in particular to an assemblage of sealing nail. 
         [0003]    2. Description of the Related Art 
         [0004]    Referring to  FIGS. 1 and 2  showing a self-sealing fastener  1  of Anderson, disclosed by U.S. Pat. No. 6,035,595, is nailed to a plank  2  with a tarpaper  21  for a meshed net  3  to be hung thereon to proceed grouting. The conventional invention consists of a sealing member  11  and a nail  12  penetrating the sealing member  11 . Wherein, the sealing member  11  includes a case  111  for the nail  12  to insert, a pusher  112  received in the case  111  for the nail  12  to insert, and an caulking unit  113  filled in the case  11  for being pushed by the pusher  112 . Moreover, the meshed net  3  is placed between the sealing member  11  and the nail head. The pusher  112  protrudes toward the orientation of the nail head which arranging the pusher  112  within the case  111 . The case  111  further has a plurality of ribs  114  externally projecting from the circumference of the case  111 , and a passage  115  defined between any two ribs  114 . In addition, the ribs  114  are further disposed opposite to where the pusher  112  protrudes. 
         [0005]    While in use, the nail  12  is hammered by relevant tools (not shown in the figures) to drill a bore and penetrate the tarpaper  21  on the plank  2 , so that the nail  12  could fix the case  111  on the plank  2  in time of the pusher  112  abutting with the nail head, and the space between the nail  12  and the case  111  could provide with a tight and satisfying hang of the meshed net  3  as shown in  FIG. 3 . During the process of hammering the nail  12 , the pusher  112  is gradually urged to forwardly push and compress the caulking unit  113  within the case  111  so as to extrude and spill the caulking unit  113  out of the case  111 . Subsequently, when the nail head densely leans against the case  111  and keep imparting the hammering force upon the case  111 , the caulking unit  113  would adhere around the nail  12  as well as outwardly scatter to the passage  115  (shown by  FIG. 3 ). As a result, the caulking unit  113  would seal where the nail  12  is nailed or the nailing bore while the nail  12  is completely inserted into the plank  2 , so that water would not permeate through the bore into the plank  2  while proceeding with grouting, resulting to a waterproof efficiency. 
         [0006]    Although the self-sealing fastener  1  has a certain sealing competence, it still has deficiencies as follows:
   1. The caulking unit  113  belongs to chemical products, and the utilization of the conventional nail set  12  has to be proceeded before the expiration of the caulking unit  113  or the expired caulking unit  113  would bring a qualitative change forth, which results in a handicap of spilling the caulking unit  113  out of the case  111  or affects the sealing competence around where the nail  12  is nailed.   2. To forcedly disperse the caulking unit  113  among the passage  115  via the compression of the pusher  112 , user has to impart a nailing or hammering force larger than the impeding force generated from the pusher  112  pushing the caulking unit  113  for urging the pusher  112  to push the caulking unit  113  with large endeavor. Accordingly, the operation of inserting the conventional nail  12  inevitably renders the exhaustion to the user and substantially decreases the operating efficiency.   3. As previously mentioned, a larger imparting force is needed to urge the nail  12 ; however, an improper overlarge imparting force to the nail  12  not only wastes labors but readily incurs the awry insertion of the nail  12 . Whereby, the case  111  would be accordingly out of kilter in view of the slanted nail  12 , and a gap would be consequently generated between the case  111  and the plank  2  as shown in  FIG. 4 . As a result, the subsequent sealing efficiency and grouting would be influenced as long as the caulking unit  113  readily comes off owing to the permeation of the construction materials while grouting.   4. The ribs  114  on the case  111  would prick the tarpaper  21  while the nail  12  penetrates the plank  2 . Even if the caulking unit  113  in the case  111  could seal the primary nailing bore where the nail  12  is nailed, the sealing scope is still limited; namely, the areas where the ribs  114  pierce the tarpaper  21  are unable to be sealed. As a result, water would in turn permeate the tarpaper  21  through those pierced holes into the plank  2  during grouting, and the waterproof efficiency is not preferably achieved.   
 
       SUMMARY OF THE INVENTION 
       [0011]    It is an object of the present invention to provide an assemblage of sealing nail, which facilitates to increase the sealing efficiency between the nail and planking as well as attain a smooth hammering operation. 
         [0012]    The present invention in conformity with the assemblage of sealing nail nailed on a plank for a meshed net being hung thereon to proceed with grouting essentially comprises a nail, a propeller for the nail to penetrate, and a blocker embedded into the propeller for the nail to further penetrate. Wherein, the propeller defines an aperture in communicated with an opened chamber thereon for the nail to penetrate. Further, the blocker has an inserting portion set in the chamber and a spreading portion connected with the inserting portion extending beyond the chamber. In this manner, while imparting a force to hammer the nail into the plank, the nail would urge the propeller and the blocker. Therefore, the blocker would be propelled under the pressure of the propeller to densely seal where the nail inserted, conducing to increasing the sealing efficiency between the nail and the plank and ensuring a smooth grouting. In addition to a larger impartation on the nail being no more needed, a swimmingly favorable nailing is also achieved.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    Before describing in detail, it should note that the like elements are denoted by the similar reference numerals throughout disclosure. 
         [0026]    Referring to  FIGS. 5 and 6  showing a first preferred embodiment of the present invention, an assemblage of sealing nail  4  is to be nailed into a plank  5  with waterproof membrane  51  for a meshed net  6  (not shown in the Figs) being hung thereon to proceed with grouting. The assemblage of sealing nail  4  essentially comprises a nail  41 , a propeller  42  for the nail  41  to penetrate, and a blocker  43  partially set in the propeller  42  for the nail  41  to further penetrate. Wherein, the nail  41  has an axial shank  411 , a head  412  disposed on one end of the shank  411 , and a tip  413  disposed on the other end of the shank  411 . Further, the propeller  42  has a top surface  421 , a bottom surface  422  oppositely disposed to the top surface  421 , an opened chamber  423  defined from the bottom surface  422  toward the top surface  421 , and an aperture  424  defined on the top surface  421  to be intercommunicated with the chamber  423 . By this manner, the nail  41  is able to justly go through the aperture  424  and the chamber  423 . 
         [0027]    Still further, the blocker  43  has an inserting portion  431  implanted in the chamber  423  and a spreading portion  432  connected with the inserting portion  431  projecting out of the chamber  423 . Whereby, the spreading portion  432  would densely abut against the bottom surface  422  while inserting the inserting portion  431  into the chamber  423 . Moreover, the blocker  43  can be made of any appropriate materials, and herein the blocker  43  is made of a material possessing soft and plastic property in the embodiments of the present invention. Concurrently, both of the inserting and the spreading portions  431  and  432  could be also penetrated by the nail  41 . Thus, while hammering the nail  41  into the plank  5 , the inserting portion  431  would be propelled by the propeller  42  for enhancing the spreading portion  432  to densely seal where the nail  41  entered. Alternatively, at least one trench  45  can be defined on the surface of the spreading portion  432 , and herein the spreading portion  432  merely defines one trench  45  thereon as shown in  FIG. 5 . Whereby, while the spreading portion  432  tightly covers on the plank  5 , the air filled in the trench  45  would be squeezed thereout to improve a preferable and firm sealing efficiency. 
         [0028]    Referring to  FIGS. 6 and 7  the assemblage of sealing nail  4  is shown in using. In practical, the assembly of the propeller  42  and the blocker  43  is usually arranged at the lower portion of the shank  411 , vicinity to the tip  413 . The tip  413  of the nail  41  is propped against the plank  5  with the waterproof membrane  51 , and the meshed net  6  is hung on the section between the head  412  of the nail  41  and the propeller  42 . Whereby, a hammering force is axially imparted to the head  412  of the nail  41  to bring the shank  411  going through the waterproof membrane  51  into the plank  5 . A nailing bore is accordingly generated. As the spreading portion  432  contacts with the surface of the plank  5 , the spreading portion  432  would force the inserting portion  431  inserted into the propeller  42  while incessantly nailing the nail shank  411 , and concurrently the propeller  42  would move forward to the head  412  of the nail  41 . When the head  412 , the meshed net  6 , the propeller  42 , and the blocker  43  are tightly fastened on the plank  5 , the chamber  423  will be entirely filled up with the inserting portion  431  of the blocker  43 , which thence renders the spreading portion  432  to be extremely extruded out of the chamber  423  as plainly depicted shown in  FIG. 7 , thereby enhancing the spreading portion  432  to concomitantly and securely enclose the nailing bore without damaging the waterproof membrane  51 . As a result, the succeeding grouting can be efficiently executed with a favorable watertight competence. Further, since the nail  41  urges the propeller  42  toward the plank  5  when they are in a firm engagement and the plank  5  also in turn props the blocker  43  into the chamber  423  of the propeller  42 , a reduced impeding force against the hammering force is attained to save user&#39;s labors, hence increasing the working efficiency. 
         [0029]    Referring to  FIGS. 8 and 9  showing a second preferred embodiment of the assemblage of sealing nail  4  comprises a nail  41 , a propeller  42 , and a blocker  43 . Wherein, the same formation, application, and efficiency of assemblage of sealing nail  4  as those of the first preferred embodiment are herein omitted. Wherein, it is adopted in this embodiment that a caulking unit  44  is filled within the opened chamber  423  and concurrently clogged with the inserting portion  431 . Further, the nail  41  is hammered to urge the propeller  42 , and the blocker  43  is set against the plank  5  to move toward the chamber  423 . In this manner, the caulking unit  44  is coincidently squeezed or compressed by the inserting portion  431  and the propeller  42  to scatteredly fill up any vacant space that is generated between the plank  5  and the assemblage of sealing nail  4 , such as the aperture  424 , the circumference of the shank  411 , and the engaging area of the spreading portion  432  and the plank  5  as shown in dotted areas. Thus, by the supplementary sealing provided by the caulking unit  44 , a preferred and solid fastening efficiency of the blocker  43 , propeller  42 , and the nail  41  is further obtainable. 
         [0030]    Referring to  FIG. 10  showing a third preferred embodiment of the present invention. Herein, the same formation, application, and efficiency of assemblage of sealing nail  4  as those of the first and second preferred embodiments are herein omitted. Wherein, it is adopted in this embodiment that the inserting portion  431  defines a reduced diameter, for instance of a structure tapering from where it connects with the spreading portion  432  to the opened chamber  423 , and the opened chamber  423  has a shape of taper correspondently with that of the inserting portion  431 . As it should be, the configurations of the inserting portion  431  and the opened chamber  423  are not restricted since the opened chamber  423  is always shaped identical to the inserting portion  431 , so that the inserting portion  431  can fully fill up the chamber  423 , and the blocker  43  can firmly seal the place where the nail  41  goes through. 
         [0031]    Referring to  FIGS. 6 and 11  showing a fourth preferred embodiment of the present invention. Herein, the same formation, application, and efficiency of assemblage of sealing nail  4  as those of the first and second preferred embodiments are herein omitted. Wherein, it is adopted in this embodiment that the aperture  424  on the propeller  42  has a first diameter adjacent to the top face  421  larger than a second diameter adjacent to the opened chamber  423  for forming a tapered aperture. In this manner, if an inexperienced user hammers the nail  41  to a slanted situation, the propeller  42  would not be influenced even if the nail  41  is skewed because the tapered aperture  424  provides the nail  41  with an adequate room to adjust. Therefore, a preferable sealing competence is still achievable, and the nail  41  as well as the propeller  42  in this embodiment would more conform to reasonable operation. 
         [0032]    To sum up, the present invention takes advantage of the nail going through the propeller and the blocker into the plank to enhance the nail urging the propeller toward the plank and accompany with the plank propping the blocker into the chamber of the propeller. When the nail securely enters into the plank, the chamber is plugged by the inserting portion of the blocker, and the spreading portion partially extended out of the chamber would substantially cover the nailing bore generated while the nail breaks in the plank to increase the sealing capability. Preferably, the increment of the caulking unit within the chamber compressed by the inserting portion also facilitates to more enhance the sealing effect and conduces to the swimmingly grouting. 
         [0033]    While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
