7 Claims. (Cl. 154-49) composite floor mat which comprises two parts, one part being a bottom mat and the other being a cover mat.
The bottom mat is composed of molded rubber or plastic material and has on its upper face upstanding integral ribs alternating with depressions which are open upwardly. The top or cover mat comprises a thin flexible sheet of plastic or rubber which is preferably of much higher quality than the bottom mat and has distributed over its under surface a plurality of lugs which cooperate with the bottom mat to prevent lateral or endwise displacement of the cover mat from its operating position on the bottom mat.
The present invention relates to a change in the ribs and lugs of the mats so that the mats can be manufactured more conveniently and the ribs and lugs can cooperate more effectively.
Various other objects and advantages will become apparent from the following description wherein reference is made to the drawings, in which:
Fig. l is a top plan view of a mat embodying the principles of the present invention, and including a bottom mat and a cover mat therefor, part of the cover that being cut away for clearness in illustration;
Fig. 2 is an enlarged fragmentary cross sectional view of the assembled cover and bottom mats illustrated in Fig. 1, and is taken on line 22 thereof;
Fig. 3 is an enlarged fragmentary sectional view similar to Fig. 2 illustrating a modification of the cover mat shown in Fig. 2;
Fig. 4 is a view similar to Fig. 1 and illustrates a modified cover mat and bottom mat, part of the cover mat being cut away for clearness in illustration;
Fig. 5 is an enlarged fragmentary cross sectional view taken on the line 55 of Fig. 4;
Fig. 6 is a fragmentary top plan view of a bottom mat and an overlying cover mat, illustrating another modification thereof;
Fig. 7 is a top plan view of a bottom mat and a cover mat showing an additional modification; and
Fig. 8 is an enlarged cross sectional view taken on the line 88 in Fig. 7.
Referring first to Figs. 1 and 2, the bottom mat 1 is composed of rubber or other flexible or resilient plastic material which is sufliciently resistant to flexure so that the mat resists distortion and is self-restoring after deformation. The bottom mat 1 as a whole, however, is sufiiciently flexible to conform to the contour of the floor of the automobile'compartment when laid'thereon. The
er quality material than that used for the bottom mat.
It is substantially the same in outline as the bottom mat so as to completely cover the bottom mat when juxtaposed thereon.
In general, the cover mat is supported on the crests of the ribs 2 of the bottom mat. However, the cover mat 4 is provided with depending integral lugs 6 distributed over the undersurface thereof and preferably arranged in rows corresponding to the rows of concavities 3 of the bottom mat 1 both transversely and lengthwise of the bottom mat. When the cover mat is laid on the bottom mat, the lugs 6 are accommodated in the concavities 3, respectively.
Each of the lugs 6 preferably is smaller in horizontal cross section at all points along its depth than the horizontal cross section of its associated concavity at the same depth. Consequently there is clearance between the peripheral walls of each lug 6 and the adjacent peripheral walls of its associated concavity 3. This clearance provides a distinct advantage in manufacture in that extreme accuracy in fit is not necessary and the problem of fitting, which occurs due to shrinkage upon curing, is substantially eliminated. However, the cover mat may be made of elastically deformable material of such quality that it can be stretched edgewise and endwise so as to dispose the lugs 6 in proper alignment with the concavities 3 so as to be receivable therein. In such case, the problem of fitting is not so great and the cross section of each lug 6 may be substantially the same as that of its associated concavity 3 at the same depth. Each of the lugs 6 is of such a depth that, when the underface of the cover mat is resting on top of the ribs 2,
the bottom of each rests on the top face of the bottom mat at the base of the depressions or concavities 3, as indicated at 7.
If desired, there may be a slight clearance between the bottom of each lug 6 and the top face of the bottom mat at the base of the associated concavity 3, when no pressure is exerted on the top mat, so as to eliminate some of the problems of fitting resulting from shrinkage during manufacture. The bottom clearance should be so small, however, that under slight pressure applied on the top mat adjacent a lug, the bottom of the lug will engage the upper face of the bottom mat.
The lugs 6 cooperate with the peripheral walls of the ribs 2 to prevent lateral and endwise displacement of the cover mat 4 relative to the bottom mat 1. Furthermore, the engagement of the bottom of the lugs 6 with the upper surface of the bottom mat exposed in the base of the concavities eliminates the danger of damage to the cover mat by the pressure of small high heels of womens shoes and the like. Also, it prevents the deflecting of the cover mat into the concavities in a manner which might cause slush, water, soft mud, and the like to squirt has upstanding ribs 11. The cover mat 12 has dependent lugs 13 similar to the lugs 6. In addition it has small Patented Oct. 22, 1957- lugs or nibs 15- which' are well distributed over its undersurface; but in amore or less randomrelation to theconcavities therebeneath so that some of the nibs may lie within the concavities while others engage the tops of the ribs. The nibs 15 assist in preventing shifting of the cover mat in theplane of the mats: Furthermore, insofar as they may engage the top of theribs 11, they tend to hold the cover mat slightly spaced abovethe ribs of the bottommat and thuspermit better'air-circulationbetween the mats;
Referring next to Figs. 4- and 5, a bottom mat 16' is illustrated in which ribs 17 are-arranged in groups. The groupsare arranged in rows" transversely andthe ribs of one. group preferably are aligned with the ribs of the. next group in the same row. In between the groups are spaces 18 which extend endwiseof the bottom mat and spaces- 19 which extend transversely of the bottom mat. The spaces 18 and 19 provide a grid of passages which are connected with thespaces or passages between the ribs. The cover mat'20is provided on' its-underside with. ribs 21 which extend transversely of the cover mat and ribs 22 which extend lengthwise ofthe cover mat. The ribs- 21- are' adapted to'fit into thespaces 19, respectively; and the ribs 22 are adapted to fit into the spaces 18, respectively. Thus the cover matis anchored against movement both endwise and transversely of the bottom mat by the coaction of the lugs 21' and 22 and lateral and and surfaces ofthe ribs'17'; The'l'ugs also stiffen. the cover mat. The cover mat maybe provided with. apertures 23 distributed over-the-surface so as to provide drainage from the top surface of the cover mat into the depressions between the ribs' of the" bottom mat.
The bottom mat has a raisedcontinuous margin which defines with the adjacent ends of the ribs channels which are in communication with the spaces or passages between the ribs and with the grid of passages 18' and 19' so that the water may flow from some of the passages intothe others. The channels between the margin and ribs may be substantially coextensive in depth with the passages between the ribs' and the passages 1'8. and 19.
Referring next to Fig. 6, the bottommat 25 is similar to the bottom mat illustrated in Fig. 4, except that, instead of the-ribs indicated at 17, which extend generally in one direction only, it is provided with ribs 26 and 27 which extend at right angles to each other and form concavities 28 which are isolatedfromeach other. These ribs are arranged in groupsv separated by passages 29. extending. transversely of the mat and. passages 30. ex tending lengthwise of the mat, these passages criss-cross. each other to form a grid. A cover mat ST is. provided; with depending ribs or lugs 32 and. 33 arranged; to fitv within the passages 29 with lateral clearance andclearance between their bottom ends and the upper surface of the bottom mat which is exposed within the passages: 29 and 30. Occasional drainage apertures 34 are providedin the cover mat.
In Figs. 7 and 8, the bottom mat 36-is provided on its lower surface with nibs or lugs 37 and on its upper surface with upstanding ribs38; The cover mat 39 is provided with apertures 40 and depending lugs 41'. The depending lugs 41 are preferably annular and are arranged. coaxial with the apertures 40 and they are so. related. tov the ribs 38 and the concavities therebetween that at. their lower edges they engage the peripheral. walls of the. concavities at a point between the bottom of the concavities and the crests of the. ribs 38. The. ribs 38. are. so. shaped that the concavities are of. inverted frustopyramidal shape.
The nibs 37 are preferably spaced so; that the covermat can be laid and stored beneath the bottom matand when: so disposedthe. nibs37 can engage the apertures 40, thus attaching. the cover matto theunderside of the bottom mat and; preventing lateral displacement; of one relative to the other. The annular lugs 41 also reinforce the covermat at themargins ofthe apertures 40:
