Latch and method of installing a latch

Abstract

Disclosed are latches with pre-molded or pre-assembled fasteners. The latch fastener can include a threaded portion and a lead in portion that is longer than the threaded portion. During installation of the latch, the lead in portion can be inserted into a cavity of a drawer to help align the latch against the cavity during installation. The built-in fastener frees one hand of the user during installation and the additional length of the lead in allows an easier alignment of the latch during installation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(9) While the present invention is susceptible of embodiments in many different forms, there is shown in the drawings, and will herein be described in detail, a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated. As used herein, the term “present invention” is not intended to limit the scope of the claimed invention and is instead a term used to discuss exemplary embodiments of the invention for explanatory purposes only.

(10) The present invention broadly includes pre-molded or pre-assembled fasteners provided within a latch. The latch fastener itself can include a threaded portion and a lead in portion that is longer than the threaded portion. The lead in portion can be inserted into a cavity of a drawer to help align the latch against the cavity during installation. The built-in nature of the fastener allows a user to free one hand during installation, rather than guide the fastener through the latch and into the cavity, and the additional length of the lead in allows an easier alignment of the latch during installation. The latch is therefore easier to install with greater efficiency.

(11) Referring to FIGS. 1-3, in an embodiment, a latch 100 can include a cover plate 105 and a hook 110 extending from the cover plate 105. A fastener 115 can be located on the cover plate 105 and can include a lead in portion 117 and a threaded portion 119. The latch 100 can further include a base 120 that connects with a corresponding shape in a cavity of a drawer to facilitate a secure connection between the latch 100 and drawer. A post 125 can also extend from the cover plate 105 and can serve as the connection point for a spring 130 with a first end 130a and a second end 130b.

(12) The cover plate 105 acts as the structural backbone of the latch 100 and can be any shape or structure that provides this function. The cover plate 105 can further serve as a cover to a cavity on a drawer when the latch 100 is coupled to the drawer, as discussed below in more detail. The cover plate 105 can also include various apertures for one or more fasteners 115 to insert through so as to couple the latch 100 to the drawer.

(13) The hook 110 can be any structure capable of holding the drawer in the closed position during use. For example, the hook 110 can have a shape and structure as shown in FIGS. 1 and 2, with a slanted surface and a notch. This design allows the latch 100 to engage the hook 110 into a catch or other structure of the drawer or cabinet by abutting the slanted portion against the catch, pushing the latch 100 downwardly as the drawer is inserted into the cabinet. During this process, the latch 100 will be biased in the upward locked against the catch due to the spring 130. The spring 130 will continue to bias the latch 100 in an upwardly position until the drawer is pushed inwardly past the slanted portion and into the notch of the hook 110 in a closed position. At this point, the latch 100 will be in the locked position, where opening of the drawer will be substantially prevented by the hook 110. To open the drawer, the hook 110 can be removed from the catch by a handle, key, or any other well-known means.

(14) The fastener 115 can be any known fastener, such as a screw, nail, tack, rod, pin, bolt, or any other structure capable of coupling two objects together. As shown, the fastener 115 can include a lead in portion 117 and a threaded portion 119. The lead in portion 117 can be larger than the threaded portion 119 to allow the fastener 115 to substantially align the latch 100 with a cavity of a drawer or other enclosure. For example, the fastener 115 can be inserted into a screw boss located in the cavity with the lead in portion 117 providing a point of alignment, and the threaded portion 119 following as a section that couples the fastener into the screw boss or other receiving portion. In some embodiments, the lead in portion 117 is longer than the threaded portion 119 to allow the fastener 115 to first align itself and then couple with the receiving portion. The smaller threaded portion 119 also allows for a quicker and easier assembly process by providing fewer threads to rotate through before the fastener 115 is completely inserted.

(15) In some embodiments, the fastener 115 can be a nail, e.g. a ring shank nail, that is pre-molded or integrally formed into the cover plate 105 and that can be hammered or otherwise impacted to couple the latch 100 to the drawer. In this embodiment, the installation process is simpler because the user can push the latch 100 against the drawer to establish a weak connection, and hammer or otherwise impact the fastener 115 to complete the coupling and assemble the latch 100 to the drawer.

(16) The base 120 can provide yet another alignment feature to improve the installation process of the latch 100. For example, the base 120 can be a male portion of the latch 100 that inserts into a correspondingly-shaped female portion of the drawer. The base 120 can press-fit or otherwise couple with the corresponding female portion to provide a temporary coupling between the latch 100 and drawer. The latch 100 can thereafter be coupled securely to the drawer by inserting the fastener 115 into the drawer.

(17) The post 125 can serve as an anchor for the spring 130 on the latch 100 side of the spring 130. For example, the post 125 can receive and couple with the first end 130a of the spring 130, and the second end 130b of the spring 130 can couple with a post or other structure within the drawer to maintain the hook 110 in the locked position, as described above. The spring 130 can be any elastic member capable of providing this bias, for example a coil spring, leaf spring, elastic material, or any other structure or material that can provide a bias.

(18) Referring to FIGS. 4-6, a drawer 10 with the latch 100 coupled or being coupled inside is shown. As shown, the drawer 10 can include an enclosure 15 for holding objects, such as tools or fasteners, assuming the cabinet holding the drawer is a toolbox. The drawer 10 can include a face 20 that encloses the drawer 10 when in the closed position, and a handle or grip 25 that a user can grip to open the drawer 10. As shown in FIG. 5, and as described above in more detail, the drawer 10 can include a cavity 30 that the latch 100 inserts into for coupling and assembly.

(19) As discussed herein, the drawer 10 can be inserted into a toolbox or tool cart. However, the present invention is not so limited and the drawer 10 and latch 100 can be utilized in any other capacity, for example, in a dresser, chest, nightstand, desk, or any other piece of furniture or other structure in which drawers are used. Further, the latch 100 need not be included with a drawer and can be a latch for a cabinet door or other structure.

(20) As used herein, the term “coupled” and its functional equivalents are not intended to necessarily be limited to direct, mechanical coupling of two or more components. Instead, the term “coupled” and its functional equivalents are intended to mean any direct or indirect mechanical, electrical, or chemical connection between two or more objects, features, work pieces, and/or environmental matter. “Coupled” is also intended to mean, in some examples, one object being integral with another object.

(21) The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
