Locking bracket and cupholder for seat frame

Abstract

A bracket is used for mounting onto the standard of a stadium or theater seat. The bracket can be bolted in place at the same time as seat backs are bolted onto the seat standard. The bracket has latches that permit a drink cupholder to be installed by sliding the cupholder along mating guides in one direction. The latches engage complementary latch portions on the drink cupholder to prevent removal of the drink cupholder. The drink cupholder has a wall that mates to the bracket, and includes skirt walls that cover the bolts used for attaching the bracket and the seat backs to the seat standard.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a drink cupholder on the seat standard or frame of stadium seats, which includes a separate mounting bracket that can be preinstalled on the standard, before the seat backs are put into place and using bolt holes that are also used for mounting the seat backs in place. The mounting bracket can be installed, and later the seat backs can be installed. A separate drink cupholder is fitted into the place on the mounting bracket as a final step and locks in position covering the bolts used for mounting the mounting bracket and sent back to prevent tampering.

In the prior art, drink container holders or drink cupholders have been advanced, and have become very popular in stadium seating for theaters, sports arenas and the like. The cupholders generally are mounted at the rear of the seat backs, so that they are accessible and useable for persons seated in the row behind the row of seats on which the cupholders are mounted. Also, separable mounting brackets and drink cupholders have been shown in the prior art. For example, U.S. Pat. No. 5,813,644, illustrates such a cupholder. Improvements in the ease of mounting, and the procedures for enabling one to install a mounting bracket at the time the seat standards are installed into the arena, and then later adding the drink cupholders, while insuring that the drink cupholders are secured in place is important. Tampering with drink cupholders can be a problem, and the cupholder of the present invention covers the bolts that attach the mounting bracket to the seat standard when the drink cupholder is snapped into place. This construction will discourage, and essentially eliminate, removal of the brackets and the drink cupholder.

The bracket and the drink cupholder can be molded out of suitable plastic materials, and provide an attractive, easily installed, and relatively tamper proof assembly.

SUMMARY OF THE INVENTION

The present invention relates to a mounting bracket and a drink cupholder that are separately made, and which are installed on the standards or frames for mounting the bracket stadium seats. The mounting bracket is adapted to snap into place on the arm support between a pair of seats, the mounting bracket extends to the rear of such standard. Molded or formed seat standards can have various curved shapes, and the present mounting bracket can easily be adapted to such curves for fitting into place, particularly along flanges at the rear of the seat standard. The seat backs are installed on provided supports at the rear of the standard with suitable bolts. The same bolts are used for securing the mounting bracket in place, so the mounting brackets can be mounted and secured at the time the seat backs are installed.

The drink cupholder that attaches to the mounting bracket can be installed at a later time by sliding it onto a provided guide wall so it snaps and latches in place. The drink cupholder is then non-removably attached without utilizing special tools. Attaching the mounting bracket to the standard at the time of installing the seat backs, makes the installation process easier.

Since the drink cupholder can be installed at a later time, it is made to shield the mounting bolts that are used for attaching the mounting bracket on the seat standard. Once the drink cup or drink cupholder has been snapped into place, the mounting bolts are not accessible from the rear but the drink cupholder is accessible to a person sitting in a seat row behind the row of seats on which the drink cupholder is installed.

Different versions of drink cupholders can be installed on the same mounting bracket, depending on the use that is desired. Each drink cupholder has a guide or slide that has recesses that mate with the lugs on the mounting bracket.

The mounting bracket is easily molded, and the drink cupholders also are molded so that they can be made rugged, in suitable colors, and with pleasing shapes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2, in particular, a stadium seat standard indicated generally at 10 is for mounting seats in a conventional manner in a stadium seating arrangement. The seats are not shown in detail, in that they can be of any suitable design. The standard 10 includes a base 12 that mounts onto a suitable support, such as a poured concrete floor of a stadium, and has frame uprights 14 at the front edge that curve upwardly to a top flange 16. The rear side of the standard has a rear upright 18, with a mounting flange 20 that is used for mounting a seat back 22, as shown schematically in FIG. 2. The seat back 22 has suitable brackets 28 that fit against the inner surface of the flange 20 in alignment with slots 24 on the mounting flange.

The flange 20 extends on opposite sides of a center panel 26, and there is a slot 24 on each of the extending side portions of the flange 20. The flange 20 and panel 26 can be curved at the rear side, as desired, and the brackets 28 used for mounting the seat backs fit this curvature.

The top flange 16, extends on opposite sides of the center panel 26, as shown, and various openings 30, can be provided. The side portions 16A and 16B of the top flange are used for supporting a mounting bracket 32 for a drink cupholder 34 in a drink cupholder assembly 36.

The mounting bracket 32 is shown in greater detail in FIGS. 3 and 4, and includes a horizontal top wall 38 that rests above the flange 16, and has snap on resilient latch fingers 40A and 40B on the two sides of the top wall 38, respectively, that fit over edges of the side flanges 16A and 16B of the top flange 16 on the seat standard.

The top wall 38 joins a support head 42 that is positioned at the rear side of the mounting bracket 32. The support head 42 in turn is joined to a support wall 44 that is molded in two wall sections, 44A and 44B, to conform to the upper portions of the flange 20 at the rear side of the standard 10. The wall 44 is provided with bolt openings or slots 46 in the lower support wall section 44B that is resting on a portion of the flange 20 carrying the slots 24 for the bolts 50 which are used for mounting the seat backs 22, and which also are used for attaching the mounting bracket 32 in position.

The support head 42 supports a generally planar upright track or wall 56 that is joined to the support head 4042with a block or web 54. The wall 56 has two latch lugs 58A and 58B formed thereon. The lugs 58A and 58B taper outwardly in downward direction and form downwardly facing shoulder surfaces 60A and 60B, respectively. The planar wall 56 mates with latch slide guides 62 at the back of the drink cupholder 34.

The back of the drink cupholder 34 has a pair of spaced side walls 61A and 61B that have upper portions 65A and 65B extending laterally from the wall 63 forming the cup receiving cylinder a greater distance than the lower portions of the wall (see FIGS. 5, 6 and 7 in particular). The upper portions 65A and 65B have inwardly turned flanges 64A and 64B that fit over the side edges of the upright track or wall 56. When the cupholder 34 is to be installed on the mounting bracket 32, the cupholder 34 is raised above the wall 56 as shown in dotted lines in FIG. 5, so that the flanges 64A and 64B are to the front side of the edges of the wall 56, and then the cupholder 34 is slid downwardly and guided along wall 56.

The wall 33 of the cupholder 34 also has a pair of latch walls 66A and 66B between the side walls 61A and 61B. The latch walls 66A and 66B have latch recesses 67A and 67B which have upwardly facing shoulder surfaces that lock under shoulders 60A and 60B of the lugs 58A and 58B for locking the cupholder 34 in place. The latch walls 66A and 66B have edges that will slide along the tapered surfaces of the lugs 58A and 58B respectively, when the cupholder is moved downwardly in the direction indicated by the arrows 74. The lower ends of latch walls 66A and 66B are tapered as shown at 70 in FIG. 5 to aid in assembly as the cupholder is slid into place. The flanges 64A and 64B will flex so that the latch walls will ramp or slip over the lugs 58A and 58B on wall 56 upon the application of a reasonable amount of force in the direction of arrow 74. The lugs 58A and 58B will snap into the latch recesses and the cupholder 34 is locked on the mounting bracket. The latch is a one-way latch. The lower end of wall 44B has a center stop lug 75 that will prevent the cupholder 34 from being slid too far downwardly.

The cupholder 34 has side skirts 76 that are spaced apart enough and have vertical length sufficient go over the ends of wall 44 and to cover the bolts 50 on both sides of the bracket 32. The side skirts 76 shield the bolts 50 from removal at the rear of the standard 10 unless the cupholder is forced off. Generally, the removal of the cupholder 34 will cause destruction of the mounting bracket or the cupholder, unless a special tool is used for resiliently bending the walls 56 and 62 to permit the lugs 58A and 58B to be released from recesses 67A and 67B.

The cupholder 34, as shown, can be in different forms. As shown in FIG. 1, the cupholder has a cup or container receptacle 80 formed by cylindrical wall 63 and also side pockets or receptacles 82 for holding various items such as a small program, or other written materials, and can have a receptacle 84 for a pen or pencil.

In FIG. 8, a modified version of the cupholder is shown at 90, installed on a mounting bracket 32. The cupholder 90 has side flanges or walls 92 that extend laterally from the main body 93 of the attachment block. The flanges 92 support rearwardly extending skirts 94 that cover the ends of the flange 20 on the standard, and the ends of the wall 44 of the mounting bracket 32, to completely shield the bolts 50, and the mounting slots or openings. The cupholder or drink container holder 90 has a receptacle 96 that receives a cup. A top wall 98 is also provided. The mounting block 93 has guides, as shown in FIG. 7. The mounting block also includes latch receptacles to receive the lugs 58A and 58B.

The mounting bracket 32 can be used for various styles of cupholders, as shown. This makes the final design of the cupholder adaptable to the particular installation that is desired. The cupholders do not have to be installed until the end of construction of the stadium. The mounting brackets themselves can be mounted at the time the standards are put in or when the seat backs are put into place.

Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
