DOORSTOP Filed July 23, 1948 fizz orizgys Patented Aug. 23, 1949 DOORSTOP Nickolas T. Anton, Park Ridge, 111., assignor to Wesco Electric Company, Inc., Chicago, Ill., a corporation of Illinois Application July23, 1948, Serial No. 40,398

1 Claim.

This invention relates to certain new and useful improvements in a door stop device and more specifically to a spring cushioned door stop device which is simple and inexpensive in construction and adapted to the purpose of cushioning the impact or shock of a door when opened.

arranged externally of the body of the door stop device itself for installing the same, thus producing an unornamental and inartistic appearance.

Accordingly an object'of the present invention is to provide a new and improved inexpensive door stop device embodying a simple, sturdy, and durable construction which may be easily installed.

Another object of the invention is to provide a suitable door stop which will provide means for cushioning the opening movement of a door so as to prevent undesirablenoise, as well as limit the opening movement of the door without marring the baseboard or wall surface adjacent thereto.

A further object of the invention is to provide in the new door stop novel means for installing the same whereby the new door stop may be easily and quickly applied to the baseboard of the wall structure adjacent to the door, and when so installed, presents an ornamental compact appearance which is due, in a large measure, to the fact that the means for installing the device are arranged within the body of the device itself.

Other and further objects of the present invention will be apparent from the following description and claim and are illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view showing the new door stop device secured to the baseboard of a Wall structure;

Fig. 2 is an enlarged longitudinal sectional view, showing the new door stop device mounted upon the baseboard;

Fig. 3 is a transverse sectional view on line 33 in Fig. 2 and Fig. 4 is a transverse sectional view on the line 4-4 in Fi 2.

A preferred embodiment of the new door stop device is generally indicated at H) in the drawing and is shown as being mounted in position upon the baseboard II of the vertical wall structure l2 which defines one side of a room to which access may behad through a door opening l3, adapted to be closed by a hinged door M, which is arranged above and perpendicular to the floor l5 of the room.

The new door stop device comprises a cylinder I 6 having a base portion I! which is provided with a central aperture I8 and concave or countersunk recess l9 adjacent to the central aperture l8, so as to accommodate a fiat headed anchoring screw 20. The anchoring screw 20 is passed through the central aperture l8 in order to mount the cylinder I6 horizontally upon the baseboard adjacent to the door l4.

A collar bearing 2| is removably mounted within the other end portion 2| of the cylinder l6 and is firmly secured to the wall of the cylinder by means of a set screw 22 which projects through .an aperture 23 which is formed in the wall of the cylinder 23 and into a threaded opening 24 which is-formed in the collar bearing 2 I.

- The collar bearing 2| is held in a fixed position when the set screw 22 is threaded into the threaded opening 24 which is formed in the collar bearing 2|.

A plunger 25 is slidably mounted within the collar bearing 2| and a rubber or like resilient bumper 21 is removably mounted upon the outer end portion of the plunger 25. To this end the rubber or like resilient bumper 21 has a recess 26 formed therein for the reception of the outer end portion of the plunger 25. The opposite and internal end portion of the plunger 25 is provided with an enlarged flange portion 28 which acts as a stop when it comes into contact with the annular collar bearing 20, thus restricting the extent of the horizontal movement of the plunger 25 and thereby preventing the plunger 25 from escaping from the cylinder member I6.

Disposed within the cylinder member I6 is a substantially cylindrical helical spring 29 one end portion of which bears against the enlarged abutment portion 28 of the plunger 25 while its opposing end portion abuts the bearing surface provided by the base portion l1 and the head of the anchoring screw 20.

The use and operation of the new door stop device shown in Figs. 1 to 3, are as follows:

The new door stop device In is shown in Fig. 1 of the drawing in the position in which it may be disposed upon the baseboard l of a vertical wall structure 2 which defines one side of a room. By reference to Fig. 2 it will be noted that the new door stop device II] is retained in operating position upon the baseboard l I by the engagement of the anchoring screw 20 with the baseboard H.

When the substantially cylindrical helical spring 29 is distended to its full extent the plunger 25 is disposed as in Fig. 2 and projects partially from the cylinder I6. However, when the flange 28 comes into contact with the annular collar bearing 2| which is securely held in place by the set screw 22, the horizontal movement of the plunger 25 is terminated and the flange 28 of the plunger 25 rests adjacent to the collar bearing 2!. When the new door stop device is secured to the baseboard l l adjacent to the door 14, and the door is opened with considerable force so as to violently contact the rubber or like resilient bumper 21 mounted on the end, portion of the.

plunger 25, the plunger member 25 will be forced inwardly, thereby compressing the substantiallycylindrical helical spring 29. After the spring 29 has received the impact from the door I4, it

will return the plunger 25 to its original position as shown. The strength of the spring 29 maybe made-commensurate to the force exerted by the door'ld on the plunger 25, and therefore will ab- .sorb all of the shock which would tend to vibrate the door it orcause damage to the vertical wall structure l2- While I have shown the new door stop device as applied. to the baseboard of the vertical wall structure, it will be understood that the new doorstep device may, if-desired, be secured to the door rather than to the wall structure, and is equally effective in either of said positions.

Itwill be seen from the foregoing description,

Y consideredin conjunction with the accompanying dra wing, that the new door stop device accomplishes its intendedobjects, and has the desirable advantages and characteristics, including those hereinbefore pointed out and others which are inherent in the invention.

While I have illustrated and described the preferred embodiment of 'myinvention, it is to be funderstood that this is capable of variation and :fall within the purview of the following claim:

I claim:

A door stop device comprising a substantially cylindrical member having an open end portion and including a base portion at its opposite end which is adapted to be mounted upon a vertical supporting surface, said base portion having a centrally arranged opening formed therein for the reception of a fastening element adapted to be passed through the said centrally arranged opening in the said base portion of the substantially cylindrical member and into the said vertical wall supporting surface, a collar guide member removably mounted in the said open end portion of said substantially cylindrical member,

1 means for securing said collar guide member within the said open end portion of the said substantially cylindrical member including a threaded opening formed in the said collar guide member, and a manually operable set screw mounted in a wall of the said substantially cylindrical member and having an inner end portion adjustably mounted in the said threaded opening in the said collar guide member, a plunger slidably -mountedin the said collar guide member and having a resilientbumper removably mounted thereon exteriorly of the said substantially cylindrical member, and a substantially cylindrical 'helicalfspring disposed within the substantially NI cKoLAs T. ANTON.
