Description

- - CLOSER FOR DOOR AND MOUNTING MOUNT FIELD OF THE INVENTION This invention relates generally to door closers and more particularly to mounting brackets for door closers.

BACKGROUND OF THE INVENTION In the current state of the art door closers in the commercial market are attached to the door or the structure of the door using very similar methods. They all use fasteners to attach the door closer directly to the door or door structure. Current door closers typically stall or drive the adjustment screws into the door closers so that during speed adjustment the user can not remove the speed adjustment screws. Staking or nailing requires an additional manufacturing process and, in the event that a regulation screw needs to be removed, it is required that the screw holes be widened in order to remove the adjustment screws.

A problem with current door closers is that after the R ^: 32040 mounting holes in the door are drilled or drilled, the door closer must be held in place as fasteners are inserted and tightened. . A door closer can weigh as much as 3.7 to 4.6 kg (8 to 10 pounds). This heavy weight must be supported while fasteners are tightened. This can make installation difficult.

Another problem with current door closers is that the typical use of rectangular shapes for mounting holes can lead to the mounting of the door closer in reverse. It is therefore required that the door closer be separated and reinstalled in the correct orientation.

The above illustrates known limitations that exist in the present door closers. Thus, it is evident that it would be advantageous to provide an alternative directed at overcoming one or more of the limitations set forth above. Accordingly, an appropriate alternative is provided which includes features completely described hereinafter.

BRIEF DESCRIPTION OF THE INVENTION In one aspect of the present invention, this is accomplished by providing a door closer having an edge at a first end thereof and a thread passage at a second end thereof; and a mounting bracket adapted to be attached to the surface of a door or a surface of the structure of a door, the mounting bracket has a retaining member that engages the door closer at a first end thereof, the member Retainer that fits the door closer fits with the edge of the door closer. The foregoing and other aspects will be apparent from the following detailed description of the invention considered in conjunction with the figures of the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS OF THE DRAWINGS Figure 1 is a perspective view of a door closer and mounting bracket in accordance with the present invention; Figure 2 is a view of the upper part of the mounting bracket shown in Figure 1; Figure 3 is a side view of the mounting bracket shown in Figure 1; Figure 4 is a left side view of the door closer shown in Figure 1; Figure 5 is a longitudinal cross-sectional view of the door closer taken along line 5-5 of Figure 4; Figure 6 is a left side view of the door closer and of the mounting bracket shown in Figure 1, showing the door closer installed in the mounting bracket; Figure 7 is a right side view of the door closer shown in Figure 1; and Figure 8 is a front view of an alternate embodiment of a door closer illustrating a novel form of mounting hole.

DESCRIPTION DETAILED Figure 1 shows the door closer 10 with a cylindrical body and its relation with the mounting bracket 50. One end of the door closer 10 has an edge 14 (shown in Figures 4 and 5) which fits with a clamp Angle or hook portion 60 at one end of the mounting bracket 50. The other end of the door closer 10 includes a thread passage 18 (shown in Figures 5 and 7) that fits with the screw 58 in the door bracket. assembly 50. The screw 58 is threaded or screwed into the interior of the threaded joint 54. Preferably, the threaded joint 54 has an angle (ie, it is greater than 0 degrees and less than 90 °) so that when the screw 58 is tightened, the door closer 10 pulls both directions, towards the flat surface 52 of the hook and mount bracket 60. Also, preferably, "threading passage 18 opens on one side (shown as 20 in figure 7) and has an angled surface 22 which is at a right angle to the shaft 58 threaded.

This design of door closer 10 and mounting bracket 50 allows a "hands-free" installation of the door closer 10. First, the four holes for the mounting bracket 50 are punched into either the door or the door frame. The door then the much lighter mounting bracket is attached to the door or door frame using fasteners (not shown) inserted in the mounting holes 70a, 70b, 74a, and 74b The edge 14 of the door closer it is inserted inside the hook 60 and the other end of the door closer 10 rotates downwards on the screw 58, with shown in figure 1 (the slot to pass 20 in the threaded passage 18 allows to join the door closer while the screw 58 is joined to the threaded or screw connection 54. The hook 60 and the edge or lip 14 in cooperation with the screw 58 and the threaded passage 18 hold the door closer freely against the bracket assembly 50 up that the screw 58 can be rotated to tighten the door closer 10 to the mounting bracket 50.

In an alternative and preferred installation method, the mounting bracket 50 is attached to the door or door structure using a plurality of self-insertion threaded fasteners that do not require pre-drilled or drilled holes, An additional feature of the mounting bracket 50 is that it retains adjustment screws 30 in the door closer 10. A regulating screw holder 62 extends from the hook 60 to close proximity with the adjusting screws 30, with which, when the door closer 10 is attached to the mounting bracket 50, the adjusting screw holder 62 blocks the removal of the adjusting screw 30 from the door closer 10, as shown in Figure 6.

In its preferred mode, the mounting bracket 50 consists of a member similar to a rectangular blade 52 with the threaded or screw connection 54 at one end and the hook 60 with the adjusting screw fastener 62 extending from the hook 60 at the other end (shown in the figures) 2 and 3). The preferred mounting hole shape is shown in Figure 2. This mounting hole shape allows only one orientation of the mounting bracket 50 after the holes for mounting on the door or door structure are drilled or drilled. This hole shape is characterized by a first pair of holes 70a, 70b that are closer to each other than a second pair of holes 74a, 74b and also because one of the first-holes 70a is misaligned in a first direction from the corresponding, or adjacent, second hole 74a and the other of the first holes 70b is misaligned in a direction opposite to the first direction of the other of the second holes 74b. In Figure 8 there is shown an alternative embodiment of a door closer 10 'with a cylindrical body 12'. For this alternative mode, no mounting bracket is used. A supporting portion or pedestal 80 is projected from each end of the door closer 10 '. The mounting hole shape 70a', 70b ', 74a', 70b ', in the support portion or pedestal 80 is similar to that described above for the mounting bracket 50. Once the holes have been punched either in the door or in the door structure, the unique shape of holes 70a ', 70b', 74a ', 70b' prevents the door closer 10 'is installed in an incorrect orientation.

It is noted that in relation to this date, the best method known to the applicant, to implement said invention is that which is clear from the manufacture of the objects to which it refers.
