, 1966 E. M. SPENCER 3,292,203
DOOR BRACKET Filed Feb. 10, 1964 p I "8/ JL9 134 fd 15 2 United States Patent 3,292,203 DOOR BRACKET Elbert M. Spencer, Wildwood, Ill., assignor to Illinois Lock Company, a corporation of Illinois Filed Feb. 10, 1964, Ser. No. 343,758 5 Claims. (Cl. 16-66) This invention relates to a bracket and more particularly to a door bracket for use with a piston and cylinder type door closer to connect the piston rod to a door.
In the past, it has been common practice to connect the end of the piston rod of a door closer pivotally or swingably to a door by pinning it to a bracket affixed to the door. Frequent opening and closing of the door over a period of time causes the pin and bracket bearing surfaces to wear. The connection becomes loose-fitting and often the pin will shear E.
The primary object of this invention is to provide a new and improved door bracket for use with piston and cylinder type door closers.
Another object of the present invention is to provide a door bracket which effectively eliminates the wear problem inherent in the presently known pin joints.
A further object of this invention resides in providing a new and improved door bracket for releasably and pivotally connecting the piston rod of a piston and cylinder type door closer to a door.
A feature of the invention is that the piston rod has opposed shoulders and the bracket has a pair of arms which extend through the grooves on either side of the rod with bearing surfaces engaging the shoulder.
Further features and advantages of the present invention will readily be apparent from the following specification and the drawings, in which:
FIGURE 1 is a perspective View of a portion of a door with a closer and bracket embodying the invention;
FIGURE 2 is an enlarged fragmentary view taken along line 22 of FIGURE 1;
FIGURE 3 is an elevation of the door bracket;
FIGURE 4 is an end view of the bracket taken along line 44 of FIGURE 2; and
FIGURE 5 is a fragmentary sectional view taken along line 5-5 of FIGURE 2.
The present invention, as embodied in the device shown in the drawings, includes a bracket indicated generally at secured to a swingable member, as door 11, for releasably and pivotally connecting the end of piston rod 13 of a piston and cylinder type closer 14 to the door. The piston rod 13 is grooved with a reduced neck portion 13a defining a pair of shoulders 13b and 130 and a head 13d.
The bracket 10 is generally J-shaped and comprises an elongate, leg portion 15 of U-channel cross-section having a pair of holes 16 and 17 therethrough which receive screws 18 and 19 for securing the bracket to door 11. The bracket has a tapered mid-portion 20 supporting a pair of spaced apart arms 21 and 22 which receive the neck portion 13a of piston rod 13 therebetween.
Each of the arms 21 and 22 has a pair of oppositely facing rounded bearing surfaces 23 and 24 which engage the shoulders 13b and 130 of the piston rod. End flanges 25 and 26 on arms 21 and 22 engage the head 13d of the piston rod to retain the rod between the arms 21 and 22 during opening and closing of the door 11. The diameterpf the head is such that it is supported by channel edges 27-28 or 29-30, depending on the direction of 3,292,203- Patented Dec. 20, 1966 opening of the door. Thus, reduced neck surface 13a is centered between the arms 21 and 22.
The oppositely facing rounded bearing surfaces 23 and 24 are spaced apart a distance substantially equal to the length of the reduced neck portion 13a of the piston rod so that the rod is held against longitudinal movement relative to the door while allowed to rock on the rounded until the shoulder portion 13b is substantially parallel to flat portion 37 of arm 21 and the piston rod can be removed from the bracket. The closer is reassembled with the bracket by reversing these steps.
Although a preferred embodiment of the invention is herein disclosed for purposes of explanation, various modifications thereof, after study of the specification, will be apparent to those skilled in the art to which the invention pertains. Reference should accordingly be had to the appended claims in determining the scope of the invention.
I claim:
1. A bracket for a piston and cylinder door closer having a piston rod with a reduced neck portion defining a pair of shoulders and a head, comprising: a leg portion fixedly secured to a swingable door and a pair of spaced apart arms which receive the reduced neck portion of said piston rod therebetween, each of said arms having a pair of oppositely directed convexly rounded bearing surfaces adapted to engage said shoulders and means on said arms for retaining said rod therebetween.
2. The bracket of claim 1 wherein said last named means is defined by an end flange on each of said arms engaging the head of said piston rod to retain said rod between said arms.
3. A bracket for a piston and cylinder door closer having a piston rod with a reduced neck portion defining a pair of shoulders, comprising: a leg portion adapted to be fixedly secured to a swingable door and a single pair of spaced apart arms which are adapted to receive the reduced neck portion of said piston rod therebetween, each of said arms having a pair of oppositely facing rounded convex bearing surface means for engaging said shoulders, and means on each arm outwardly of said surface means for retaining the piston rod between the arms for enabling said shoulders to rock on said rounded surface means during movement of said piston rod.
4. A bracket for a piston and cylinder door closer having a piston rod with a reduced neck portion defining a pair of shoulders and a head, comprising: a leg portion adapted to be fixedly secured to a swingable door and a single pair of spaced apart arms which are adapted to receive the reduced neck portion of said piston rod therebetween, each of said arms having a pair of oppositely directed rounded convex bearing surface means adapted to engage said shoulders for enabling said shoulders to rock on said rounded surface means during movement of said piston rod, each of said arms having an end flange for engaging the head of said piston rod to releasably and pivotally retain said rod between said arms.
5. A door closer assembly comprising: first and second members mounted for longitudinal movement relative to one another; means forming a recess inwardly of one end of said second member and extending thereacross to define shoulders at opposite sides of the recess; a first bracket connected adjacent one end of said first member; and a second bracket connected adjacent said one end of said second member, said second bracket including a mounting portion and a pair of arms extending outwardly from said mounting portion, each arm including a first portion extending across said recess and a second portion at the end of said first portion having means for retaining said second member between said arms, said first portions each having an accurate abutment surface on opposite sides thereof, each abutment surface being engageable with one of said shoulders for moving said second memher in one direction relative to said first member, and: each abutment surface :being convex to accommodate, pivoting movement between said second member; and said 1 second bracket and to provide substantially point contact;
between the abutment surfaces and the shoulders to minimize wear therebetween.
