BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a key holder, and more particularly to a key holder, which can receive keys within it and is safe and convenient to carry and use.
2. Description of the Related Art
At present, it is common for people to amass a large number of keys on a key ring. However, the keys are usually not contained in any kind of holder such that they hang out in the open and can easily hurt the user or others if not careful. The keys can also cause damage to surfaces or other objects if the user is not careful.
Therefore, the invention provides a key holder to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a key holder, with which it is convenient for a user to carry keys safely.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIG. 1, a first embodiment of a key holder has a seat (10) and a housing (40).
The seat (10) comprises a key (20) and a base (30) in which the key (20) is mounted. A tongue (21) is integrally formed in a lower end of the key (20) and a channel (31) is longitudinally defined in a center of the base (30). The tongue (21) is inserted into the channel (31). A notch (22) is transversely defined in the tongue (21). A threaded hole (32) is defined in a side of the base (30) and communicates with the channel (31).
The housing (40) has a chamber (41) longitudinally defined therein forming a box with an open end. The base (30) with the key (20) can be inserted into the housing (40) and slide freely up and down within the chamber (41). A slot (42) is longitudinally defined through a side of the housing (40) and in communication with the chamber (41). A stopping edge (43) is formed at the open end of the housing (40) closing the end of the slot (42).
A screw (50) has a head (51), the diameter of which is slightly larger than that of the slot (42), integrally formed in an end thereof and a thread (52), the diameter of which is slightly smaller than that of the notch (22), extending from the head (51). The thread (52) is securely mated with the threaded hole (32) and securely fastened to the notch (22). In other embodiments of the present invention, the screw (50) can be any type of fastener.
With reference to FIGS. 1 and 2, the key (20) is inserted into the channel (31) and the base (30) is inserted into the chamber (41). The screw (50) is inserted so that the thread (52) extends through the slot (42) and into the threaded hole (32) in the base (30). The thread (52) also extends through the notch (22) in the tongue (21) of the key (20) thereby securing the key (20) in the base (30). The head (5) remains outside of the housing (40) abutting the slot (42). When the head (51) is pushed upwards along the slot (42), an end of the key (20) extends out of the chamber (41) to be used. When the head (51) abuts the stopping edge (43), the key (20) cannot be pushed farther and will not be separated from the housing (40).
With reference to FIG. 3, a second embodiment of the invention is the same as the first embodiment except that the second embodiment has a housing (60) which has two chambers (61) longitudinally defined therein and in alignment with each other. Two seats (10), each of which is composed of a key (20) and a base (30), are received respectively into the chambers (61). Two slots (62) parallel to each other are longitudinally defined through a side of the housing (60) and in communication with the chambers (61). Hence, each key (20) is fastened to each base (30) with a fastener (50) being inserted into each slot (62) and through each threaded hole (32). The operation of the second embodiment of the invention is similar to that of the first embodiment.
With reference to FIG. 4, a third embodiment of the invention is the same as the second embodiment except that the third embodiment has a housing (70), which has three parallel chambers longitudinally defined therein. The operation of the third embodiment of the invention is similar to that of the second embodiment.
With reference to FIGS. 5-7, a fourth embodiment of the invention has a box (80), which has an open end and two chambers (81) defined therein and in alignment with each other. A single housing (40) and a double housing (60) are received respectively into the chambers (81). Multiple slots (82) are defined in two sides of the box (80) and correspond to the slots (42)(62) in the housings (40)(60). The seats (10) are received into the housings (40)(60) and the housings (40)(60) are received into the box (80). The fasteners (50) are inserted through the slots (82)(42)(62) in turn and fastened in the threaded holes (32). Hence, the keys (20) are secured in the bases (30) and the seats (10) can slide within the chambers (81). A cap (90), which is configured to mate with the box (80), is mounted over the open end of the box (80) thereby preventing dust from entering the box (80). The operation of the fourth embodiment is the same as that of the previous embodiments.
The advantages of the present invention are described as follows:
1. The keys (20) are contained within the key holder when not in use to prevent injury or damage to persons or objects nearby.
2. A key (20) can be quickly and easily extended for use. When the keys (20) are retracted within the housings (40)(60), the key holder has an attractive appearance and the keys (20) are separated so they will not strike each other and make noise.
3. The key holder can be configured to hold different numbers of keys (20).
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
