3 Claims. l
lThis invention relates to display cases for cigars and the like and more particularly to an improved means for maintaining the interior of the case in a humid state necessary ior preserving in proper condition the cigars or other such goods displayed in the case.
Among the principal objects of the present invention isto provide a simple and inexpensive humidifying system for display cases which is adapted for ready and convenient installation therein, which is relatively inconspicuous and occupies a minimum of space in the case and which insures uniform and constant distribution of moisture throughout the interior of the case.
More particularly, it is a further object of the present invention to provide a humidifier for display cases which is constructed of simple pipe sections adapted to be cut into suitable lengths and assembled to fit within the interior of cigar cases of any size and shape, the assembled sections providing for a wide distribution of moisture derived from water introduced into the pipe system, as desired, at a single convenient point.
Other objects and advantages of the invention will be apparent hereinafter, it beingunderstood that the present invention consists substantially in the combination, construction, location and relative arrangement of parts, all as described in detail hereinafter, as shown in the accompanying drawings and as finally pointed out in the appended claims.
In the accompanying drawings, which are illustrative of a preferred embodiment of the present invention,
Figure l is a perspective view showing the humidier of the present invention installed within a display case such as is conventionally used for displaying cigars;
Figure 2 is a bottom plan view of a part of a humidifying system as viewed upwardly from the horizontal plane of the line 2-2 of Figure 1;
Figure 3 is a view showing the component elements of one section of the humidifying system;
Figure 4 is a horizontal sectional view of a corner connection between a pair of sections as taken on the line 4--4 of Figure l;
Figure 5 is a vertical sectional view taken on the line 5-5 oi Figure 1; and
Figure 6 is a vertical sectional View taken on the line 6-6 of Figure 1.
Referring now to the drawings and more particularly to Figure 1 thereof, it will be observed that the humidiiier apparatus of the present invention, as installed within the display case I0, essentially consists of a system of interconnected humidifying conduits II, I2, i3 and I4 commonly disposed in a substantially horizontal plane adjacent the top of the case, the conduits being supported in their elevated position by a plurality of vertically extending standards I5 respectively disposed in the several corners of the display case. It will be understood, of course, thatl the interconnected humidifying conduits may be of any required number to provide a shape to the assembly which corresponds generally to the shape of the case. Thus, while in the arrangement as illustrated, four such conduits are assembled into substantially rectangular form, any other polygonal form may be obtained by employing the requisite number of interconnected conduits, the present invention being not limited, of course, to the shape of the conduit system.
Each of the humidiiying conduits of the system consists of three separate elements as shown in Figure 3, namely, an outer member I6 oi tubular form slotted along its entire length, as at I1, an inner tubular member I8 provided along one side thereof with a series of longitudinally spaced apertures I 9, and an intermediate pad 20 of porous material, such as sponge rubber, felt or water absorbent material. Each of the outer members I6 is provided at its opposite ends with annular flanges 2l, while each of the inner members i3 is likewise provided at its opposite extremities with anges 22, it being noted that for each conduit assembly the inner perforated member I8 is somewhat longer than its associated outer slotted member I6, this for a purpose which will be apparent hereinafter.
In the assembly of the associated elements I6, I8 and 2U, as shown most clearly in Figures 2 and 6, the member I6 is disposed with its longitudinally extending sloi-l I'I presently downwardly and in longitudinal registry with the perforations I9 of the inner member I8, the water absorbent pad 20 being interposed between the concentrically arranged tubular members I6 and I8 in the region of the registering slot I 1 and perforations I9.
Adjoining assemblies of the elements I6, I8 and 2li are secured together by suitable corner fittings 23 generally in the shape of elbows having opposite externally threaded ends 24--24 adapted respectively to be tted with flanged clamping rings 25 embracing opposite ends of each assembly. As most clearly appears in Figures 2 and 4, the ange 26 of the clamping ring 25 engages the end flange ofthe external slotted member I5 of the conduit assembly and `draws it toward the end of the elbow fitting 23 when the clamping ring is threaded onto the latter. Suitable washers 21 and 28 are respectively interposed between the flanges 2| and 22 of the concentric members I6 and I8 and between the flange 22 and the elbow, in consequence of which a secure joint is obtained between the assembled parts to insure free and continuous communication throughout the full circuit of the interconnected internal apertured members I8. Thus, water passing through the fittings 23 can only ow into the interior of the members I8 for discharge therefrom downwardly by way of the perforations I9 to thereby moisten the pads 20 disposed between the perforations I9 and the bottom slots I'I of the external members I6.
It will be understood, of course, that the humidifying system consisting of the several interconnected assemblies of the elements I6, I8 and 2II- provides a continuous circuit for the now of water through the interiors of the interconnected perforated members I8 with the result that the several water absorbent pads of the system are constantly and uniformly moistened by the water discharged through the perforations I9. These uniformly moistened pads 20 then give up the moisture accumulated therein through the slots Il of the members I6, these slots being in such free communication with the interior of the display case as to provide for constant wide-spread and uniform humidification of its interior.
In order to provide the :conduit system with its necessary supply of water, any one or more of the elbow fittings 23 may be provided in its top side with an opening 29 through which water may be delivered into the system in suicient quantity and at periodic intervals, as required, to maintain the several pads 20 in thoroughly moistened condition. Preferably, in order to facilitate such introduction of water into the system, the opening 29 may be internally threaded for acceptance of a funnel element 30.
To support the interconnected sections of the conduit system in desired elevated position with.. in the display case, it is preferred to employ standards, such as l5, the upper ends of which are threadedly fitted into suitable sockets 3l formed in the bottom sides of each of the elbow fittings 23. Of course, any other suitable arrangement may be employed for supporting the system in position within the display case.
It will be understood, of course, that the present invention is susceptible of various changes which may be made from time to time without departing from the general principles or real spirit thereof, and it is accordingly intended to claim the same broadly as well as specifically as indicated by the appended claims.
What is claimed as new and useful is:
1. A display case humidier comprising a, continuous conduit system including a plurality of interconnected sections each including a pair of concentric tubular members and a water absorbent pad disposed 'between' and extending lengthwise of said members along the bottom sides thereof, the inner of said members being provided with a series of longitudinally spaced apertures in registry with a longitudinally extending slot formed in the bottom of the outer of said members.
2. A display case humidifier as dei-ined in claim l wherein the several sections of said system are disposed in a common horizontal plane case.
3. A display case humidifier comprising a, system of interconnected conduits for distributing moisture throughout the interior of a display case, said system including a plurality of interconnected tubular members perforated longitudinally along their bottom sides, a water absorbent element covering said perforated portions of each tubular member, means for securing said water absorbent elements in covering relation with respect to said perforated portions of said tubular members, said means providing free escape of moisture from said elements into the interior of said display case, said last-mentioned means including longitudinally slotted tubular elements concentrically arranged about said perforated tubular member with the longitudinal slots thereof disposed exteriorly of the water absorbent elements and in registry with the perforations of said tubular members.
