Background of the Invention
1. Field of the Invention
The invention relates to a retractable device for attachment to an article and, more specifically, a retractable device with means for holding the article adjacent the retractable device during storage.
2. Description of the Prior Art
The retractable device is generally used in conjunction with checking fixtures. A check fixture is used to verify that plastic, metal or other material parts conform to drawing specifications. A check fixture utilizes gauge plugs, pins, temps and other loose details to verify part configurations.
These loose details were previously attached to the check fixtures with a thin wire cable. These loose wire cables (approximately 2 feet in length) were always getting tangled, broken or just generally in the way. These loose cables would allow the attached details to slip or fall from fixtures, inadvertently causing the replacement of many lost or damaged details. Thus increasing the number of accurate gauging devices which must be purchased.
It is therefore desirable to provide a retractable holder. This holder can be mounted on the fixture and connected to the details in order to confine the details to the work area. Causing fewer gauging devices to be lost or damaged.
Summary of the Invention
A retractable holder for an article includes a housing having a hollow inner compartment. The hollow inner compartment is defined by a first wall, a second wall spaced from the first wall and disposed generally parallel to the first wall, and a peripheral side wall disposed generally perpendicular to the first and second walls. The housing encloses and stores flexible means for attaching the article to the housing. The flexible attaching means is extendable externally from the housing. Means for retracting the flexible attachment means is also enclosed with the housing. Preferably, the retractable holder also includes means for locking the retracting means with the flexible attaching means in an extended position, and means, connected to the housing, for holding the article adjacent to the housing for storage.

Description of the Preferred Embodiment
An exploded cross sectional view of the retractable holder of the present invention is shown in FIG. 1. The housing 10 of the retractable holder includes a first housing member 12, and second housing member 14. The first housing member 12, as shown in FIGS. 1 and 7, includes a first wall 16 and a peripheral side wall 18. The first wall 16 has a first slot 24 spaced inwardly from the peripheral side wall 18. A fastening stud 20 is integrally formed with the first wall 16 of the first housing member 12. A central aperture 28 is also formed in the first wall 16 of the housing 10. A retaining ridge 22 is formed integrally to the first wall 16 of the first housing member 12 which assists in retaining a rotatable holder 34 within the housing 10.
The second housing member 14, as shown in FIGS. 1 and 5, has a second wall 44 disposed generally parallel to the first wall 16 of the first housing member 12. The second housing member 14 also includes a peripheral outer wall 46 and inner wall 48. Preferably, the inner wall 48 can define a central aperture 50 which is aligned with the central aperture 28 in the first wall 16 of the first housing member 12. The central apertures, 28 and 50 respectively, can be used to attach means for holding an article 70, such as a gauge device, adjacent to the housing 10 for storage. The holding means can be a clip 64, such as the spring clip as disclosed in U.S. Pat. No. 1,711,730, a hook, a magnetic, or the like depending on the article 70 to be stored. The central aperture 28 and 50 respectively, can also be used to attach means for mounting the retractable holder in a desired location, such as clip, clamp, or hook for mounting the housing 10 adjacent to the machine apparatus, or for attaching to the belt of the operator. A third slot 58 is formed in the peripheral outer wall 46 of the second housing member 14. When the first housing member 12 is connected to the second housing member 14, the second slot 26 is aligned with the third slot 58 to form an opening through the peripheral side walls, 18 and 46 respectively, to a hollow inner compartment within the housing 10. A second retaining ridge 54, is formed integrally with the second wall 44 of the second housing member 14 and is aligned with the first retaining ridge 22 of the first housing member 12 to retain a rotatable holder 34.
The second housing member 14 includes fastening apertures 52 in the second wall 44. The aperture 52 is aligned with the fastening stud 20 of the first housing member 12, such that the fastening stud 20 will pass through the aperture 52 when the second and third slot, 26 and 58, respectively, are aligned. Preferably, the first and second housing members, 12 and 14 respectively, are constructed of plastic. This permits the fastening stud 20 to be heat staked to hold the first and second housing members together. It should be apparent that other means for securing the first and second housing members, 12 and 14 respectively, are included within the scope of the invention. For examples, the fastening stud 20 can be threaded and a fastening nut can be attached thereto to secure the first housing member 12 to the second housing member 14, or a fastening member, for example a bolt 30 and a nut 32, can be passed through the central apertures, 28 and 50 respectively, to connect the first and second housing members together.
The holder 34, as shown in FIGS. 1 and 6, has a central aperture 36 and is rotatably connected to the inner wall 48 of the second housing member 14. The holder 34 includes a third wall 38 and a peripheral side wall 40. The holder 34 rotates about the inner wall 48 of the second housing member 14 and is retained by the first and second retaining ridges, 22 and 54 respectively, formed on the first and second housing members, 12 and 14 respectively. The third wall 38 is disposed generally parallel to the first and second walls, 16 and 44 respectively, of the housing 10. The third peripheral side wall 40 is disposed generally perpendicular to the first and second walls 16 and 44, respectively. The third peripheral side wall 40 is spaced inwardly from the first and second peripheral sidewalls, 18 and 46 respectively, of the first and second housing members, 12 and 14 respectively.
Flexible means for attaching an article 70 to the housing 10 are provided. The flexible attaching means, is extendable externally from the housing 10 through the second and third slots, 26 and 58 respectively, in the first and second sidewalls, 18 and 46 respectively. The flexible attaching means generally includes an attachment member 72 having a generally circular cross-section and a finite length. The attachment member 72 is anchored at one end to the holder 34 and connected at another end to the article 70. The member attachment 72 is coiled around the third peripheral side wall 40 of the holder 34 for storage within the hollow inner compartment of the housing 10. It should be apparent that attachment member 72 can be selected from a group consisting of a cable, cord, wire, string, rope, filament, fiber, and thread. As shown in FIGS. 1 and 6, the attachment member 72 of the present invention is connected to the holder 34 through an anchoring aperture 42 in the third peripheral side wall 40.
Means for retracting the flexible attaching means are provided within the housing 10. The retracting means can include a coil spring 74 retained within the third peripheral side wall 46 of the holder 34. Suitable spring connections, 66 and 68, are formed on the third peripheral side wall 46 of the holder 34 and the inner wall 48 of the second housing member 14. The coil spring 74, as shown in FIGS. 1 and 6, biases the holder 34 to rotate in an attaching-means-retracting direction.
The invention preferably includes means for locking the retracting means with the flexible attaching means extended in a desired position. The locking means can include a locking member 76, as shown in FIGS. 1 through 4. The locking member 76 is disposed in the first slot 24 of the first housing member 12 with one end extending externally to the housing 10 and another end slidingly engaging the third wall and third peripheral side wall, 38 and 40 respectively, of the holder 34. At least one notch 78, shown in FIGS. 1, 2, and 6, is formed in the third wall 38 adjacent the third peripheral side wall 40 of the holder 34. The notch 78 is intermittently disposed adjacent the first slot 24 in the first wall 16 of the first housing member 12 as the holder 34 rotates. An angled edge 80 of the locking member 76 is engageable with the notch 78 in the holder 34 to lock the holder to prevent rotational movement of the holder 34 until the locking member 76 is disengaged from the notch 78. The locking member 76 includes a flared portion 82 external from the housing 10, and a protruding portion 84 within the housing 10 to retain the locking member 76 in the first slot 24 of the first housing member 12.
The first housing member 12 encloses the second housing member 14 with the first peripheral side wall 18 disposed externally of the second peripheral side wall 46, the fastening stud 20 aligned to pass through the fastening aperture 52 in the second housing member 14, and the second slot 26 aligned with the third slot 58 forming an opening from the hollow inner compartment of the housing 10. The holder 34 is rotatably connected to the inner wall 48. A coil spring 74 is retained within the holder 34 and is connected to the third peripheral side wall 40 at one end and the inner wall 48 at another end. The attachment member 72 is anchored to the holder 34 within the housing 10 at one end and attached to an article 70 at another end external to the housing 10. The attachment member 72 passes through the opening defined by the aligned second slot 26 and third slot 58. A finite length of the attachment member 72 is coiled around the third peripheral side wall 40 of the holder 34 and stored within the hollow inner compartment of the housing 10. The article 70 can be removed from the storage clip 64 when needed. The attachment member 72 is pulled out of the housing 10 through the opening defined by the second and third slots, 26 and 58 respectively. As the attachment member 72 is dispensed, the holder 34 rotates which tightens the coil spring 74 through the suitable spring connections, 66 and 68 respectively. As the holder 34 rotates, the locking member 76 slidingly engages the third wall and third peripheral side wall 38 and 40 respectively. When the desired length of attachment member 72 has been dispensed, the rotational velocity of the holder 34 slows, thereby permitting locking member 76 to engage within notch 78 to restrain the holder 34 against further rotation in either direction. When it is desired to retract the attachment member 72, the locking member 76 can be disengaged by pulling upward on the locking member 76, or by pulling out a small additional length of attachment member 72, the locking member 76 will be disengaged from notch 78 and the dispensed length of attachment member 72 can be retracted into its stored position coiled around the third peripheral side wall 40 of the holder 34 within the hollow inner compartment of the housing 10.
Various modifications to the form and construction of the retractable holder may be resorted to without departing from the spirit of the invention disclosed herein.
