This invention relates to a floor pad and has to do particularly with a pa/d'which af fords a degree of resiliency yet one which will not hold or confine dirt or dust, and

which is of a construction that will not unduly mar or soil articles which come in contact with it.

The invention is concerned particularly with a mat which is useful in a pit at the end of a bowling alley. Of course, the invention is not limited to a mat to be used in this loca-' tion only, as the construction may be employed in any place desired as for example, runners behind counters, or fountains, or used adjacent machines or the like.

In order that the advantages of the mat may be better understood, it will be described with respect to the requirements of a mat in a bowling alley pit. The pins and the balls, which are relatively heavy, strike the floor of the pit with considerable impact and of course some sort of a mat or pad is necessary to preserve the pins and balls, and also to preserve the floor which would become splintered and in turn further damage the pins and balls, A rubber mat has been used but this is undesirable because a pin which slides across it receives a mark. Furthermore, particles of dust and grit readily collect and this grinds into the wooden pins and balls. Mats of fabric construction such as inter-woven strands of rope-like material or the like or cocoa mats have been used,but they not only wear out quickly but also collect the dust and grit which in turn soils the pin which is 1mdesirable and results in that the pin has to be cleaned and re-finishe'd at short intervals of time.

, The present invention contemplates a mat 40 construction which comprises generally spaced strips of relatively flexible material which are supportedby resilient elements.

The mat accordingly is more or less of an open work construction which will afford the 45 desired resiliency but which will permit particles of dirt and grit to pass through.

In the accompanying drawings:

Fig. 1 is a plan view of a mat constructed in accordance with the invention.

Fig. 2 is a perspective view of a portion of a mat having a part cut away to show the construction.

The mat is made up of a plurality of relatively long strips of material which are disposed in spaced relation and which preferably are parallel. These strips may be of different materials depending upon the requirements of the use to which a particular mat is to be used. Cushioning devices support these strips and these devices essentially are relatively long lengths of a material of a resilient nature disposed in spaced relation and extending cross-Wise or substantially cross-wise of the first mentioned strips. Ordinarily the two sets of strips will be disposed at right angles to each other. The two sets of strips are adjoined preferably at each point of crossing.

The specific structure will be appreciated by reference to the drawings wherein strips 1 are shown, and it will be noted that the mat comprises a plurality of these strips disposed in spaced manner. The resilient supporting elements are preferably of rubber. These elements are also preferably in the form of long lengths or strips and are disposed at right angles, preferably, to the strips 1. They are illustrated at 2. An advantageous form-for the supporting strips is that of a curved or substantially semi-circular or U-shape in cross section. The legs of the U as illustrated at 3 and 4 are designed to contact with the supporting floor while the upper-most strips are connected to the supporting strips substantially at the bight portion thereof. The strips may be secured together by one or more rivets 5.

When a mat of this construction is to be used for example in a pit at the end of a bowling alley, it is preferable that the strips 1 be of fiber. Strips which are approximately 1 inches wide by of an inch in thickness have been found quite satisfactory. The mat protects the floor but due to its open construction allows all dirt and grit, etc., to pass through onto the supporting floor. Accordingly the pins do not become soiled as readily as they do with a mat which collects and retains the dirt. Moreover objectional marks are not placed on the pins as they slide over the fiber strips. The fiber strips are adapted to contact withafloor,said legs relatively strong so that there is no breakage adapted to spread under load and the sal in the event of a pin or ball striking heavily elements beings aced apart sufliciently to on a strip between two supporting members. permit of free an independent spreading of The semi-circular or U-shaped formation the legs of each element. of the supporting elements render consider- 3.
