14 Claims.
This invention relates to a clock, and without being limited thereto, is particularly applicable to an electric wall clock. In the past one of the problems connected with wall clocks was the necessity of supplying them in several colors so that the purchaser could select a color to suit the decorative scheme of the room in which the clock was to be used. The manufacturer wasv also faced with a second problem, namely the length of the electric cord. If the cord were made long enough to reach the electrical outlet in certain locations, it was sure to dangle when hung in a location nearer to an outlet.
Therefore, one of the objects of the present invention is to provide a clock having a case part that is removable Without tools so that the consumer can change the color scheme of said clock by merely replacing said case part.
A second object is to provide a clock having means to support a cord on the clock so that the consumer may select the length of cord that hangs from said clock or he may conceal the entire cord.
Another object is to provide an improved clock that may be manufactured for low cost and is exceptionally simple to assemble.
Other objects and advantages will be apparent from the following description of a preferred embodiment of the invention taken in conjunction with the accompanying drawings in which:
Fig. 1 is a front elevational View of a clock embodying the invention;
Fig. 2 is a back elevational view of said clock;
Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 2, with the cord not shown;
Fig. 4 is a front elevational View of a detachable case part removed from the clock case;
Fig; 5 is a cross-sectional view taken on the line 5-5 of Fig. 4;
Fig. 6 is an elevational View of the back plat removed from the clock; and i Fig. 7 is a cross-sectional view taken on the line l-l of Fig. 6.
Referring now to Fig. 1, reference numeral I0 designates a clock case preferably moulded of plastic, but which may be made of other suitable materials, such as wood or metal.
The case IU includes a central portion I I generally hemispherical in shape; a series of cut-out numerals or other indicia I2 surrounding said central portion; and a ring portion I3 surrounding said numerals. A series of cut-outs or openings I4 in the case are defined by the outer border of the central portion I I, the inner border of the ring portion I3 and the spaced numerals l2. A
removable ring I5 is positioned behind the numerals I2 so that portions of the ring can be seen through the openings I4.
Turning now to Figs. 2 and 3, three bosses I6 are moulded in the rear of the central portion I I of the case. A back plate I'I is secured to said bosses by self-tapping screws 98. As will be further described, the back plate I1 performs several functions including supporting the movement, providing a receptacle for the electric cord, and providing fastening means for the removable ring I5.
The back plate Il may be made of any suitable material, but steel or aluminum is preferred. The back plate is formed with a raised central portion I'8 generally circular in outline except for a sector I9. The sector I9 and a iiange 20 are in the same plane. As shown in Fig. 2, when the back plate I1 is assembled in the clock case an annular channel 2l, having a U-shaped cross-section, is formed by the raised portion I8, the flange 20 and the inside of the central portion I I of the clock case.
Two series of lingers are formed on the periphery of the iiange 20. In one series, four ngers 22 are bent toward the center of the back plate so that they project over the channel 2l and almost touch the raised portion I8. The purpose of these iingers is to retain an electric cord 23 in said channel.
A second series of fingers 24 project from the flange at right angles, and are bent over outwardly at their ends. The lingers 24 should be resilient or spring-like. Therefore, if the back plate II is made of a material such as aluminum, it may be preferable to fasten steel fingers 24 to the yback plate by suitable means. When the removable ring I5 is pressed into the back of the case, the fingers 24 are bent slightly inward so that their resiliency serves to hold the ring I5 in place by pressure on the inner periphery.
The clock movement 25 is conventional and may be either synchronous motor driven or spring driven. In this example a synchronous motor type is shown. The movement 25 is supported by three screws 26 that pass through rubber grommets 2'I to secure the movement to the back plate I'I. The movement 25 drives three hands 30 by means of co-axial shafts 3 I.
The electric cord 23 passes from the movement 25 through a grommet 28 and is coiled in channel 2I where it is held in place by fingers 22. If the clock is to be used with a standard receptacle, just enough cord to reach the receptable is unwound from the channel. Thus there need. by no clock Will be sold to the consumer With one orf more rings I5. Each ring will be furnished Withone color on the front and another on the back.
Thus to change the color v"sblieriie of "the"einemy the consumer need merely piislii-n thefrntof-fthe ring releasing it from the spring lingers 24.
lThe ring could then be reversedand replaced in the clock case by pressing on the back ofthe ring.
The spring ngers Wouldthen hold it 'platef- If the customer is not satisfied with the colors furnished, he may purchase otherrings lor'color his own ring. It will be'see'n' that both the manu: facturers and the dealersstock'mayJ-be reduced since only one ndel vneedbe` stocked-with a variety of rings to be offered tothe' 'customer vto give him his choice of color.
Obviously, the invention is not-limitedl to the details the described embodiment, since thes' may be modified. Moreover, it is notindispensible that all of the ieaturesof the inventionbe used conjointly sinfc'e "certain'vfeatures'fmay bev used to advantage in different combinations.
