Description

Nov. 5, 1940. R. BERNHARDT PANEL 2 Sheets-Sheet l Filed April 4, 1938 9 1 A v-v-aa/vav Patented Nov. 5, 1940 UNITED STATES PANEL Bay Bernhardt, Portland, Oren, assignor to M and M Wood Working Company, Portland, reg., a corporation of Oregon Application April 4, 1938, Serial No. 199,886 1 Claim. (Cl; 20-91) This invention relates to the construction of panels and analogous articles. and more particularly to that style of panel made up of stiles and rails constituting a frame and having veneered surfaces.

The construction is characterized primarily in that the panel comprises two face sheets or veneers held rigidly in spaced apart relation by a core member comprising sheet material so fashioned as to be alternately secured to the opposed surfaces of the separated face sheets or veneers to form a truss or bridging therebetween.

It is an object of the invention to provide a panel for use as a door and the like which will 16 eliminate or greatly minimize the tendency of the panel to distortion or warping when in use. It is a further object of the invention to provide a panel or analogous article comprising a frame overlaid with veneers and having a core 0 member therefor disposed within said frame intermediate said veneers consisting of material secured at angularly spaced intervals to opposed surfaces of the face veneers in the form of a truss, resulting in a panel which is strong and durable in construction, light in weight, and simple and economical to manufacture.

A particular advantage of the construction is that it provides a multiple number of air spaces throughout the panel, or, in a modified construction, a multiple number of inter-communicating spaces. which may be filled with an insulating material to make the panel impervious to heat or cold, and sound. The construction is adapted to a wide variety of uses, being particularly advantageous when used for doors.

With these and other advantages and objects in view, the invention resides in the novel construction and combination of parts hereinafter described, illustrated in theaccompanying drawings and set forth in the appended claim; it being understood that various changes in form, proportion, size and details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

- In the drawings:

Figure 1 is a perspective view of the core member for a panel embodying the present invention.

Figure 2 is a perspective view of the core member affixed to the stiles and rails of a door frame, a portion of the frame being broken away to better illustrate the position of the core member with respect to the frame. 7

Figure 3 is a perspective view of a portion of a finished panel, one of the stiles being removed to better illustrate the arrangement of parts.

Figure 4 is a front elevation of a panel constructed according to the present disclosure, a portion of the face veneer being broken away.

Figure 5 is a front elevation of a panel illustrating an alternative method of mounting the core member in the frame.

Figure 6 is a perspective view of a panel illustrating a modified form of construction embody- 10 mg the invention.

Figure 'l is an enlarged fragmentary view of the core member illustrated in Figure 6.

Figure 8 is a sectional elevation of a panel, taken on the line 8-8 of Figure 6. 1

In its simplest embodiment, the invention consists of a panel comprising a frame made up of stiles I and rails 2, and having a core member 3 secured to either the stiles or rails and occupying the space bounded thereby. To each side of the 20 frame is secured a'face sheet or veneer 4, providing a flush exterior surface for the panel.

In constructing the panel the stiles and rails are first assembled to create a frame of the desired shaped and dimensions, one surface of each 25 of two oppositely positioned frame members being grooved along the inner edges thereof, as at 5, to receive the end portions 6 of the core member 3. The core member is composed of sheetlike material, and is so'fashioned as to be alterso nately secured to the opposed surfaces of the face sheets 4-4 at angularly spaced intervals, Thus the core member consists of a series of interconnected oppositely disposed surface engaging portions 1, intermediate which the core member is 35 angularly disposed to create the struts or bridging sections 8. It will be appreciated that the thickness of the core member, 1. e., the distance between the parallel planes of the oppositely disposed surface en in portions 1, must be exactiy the same as the thickness of the frame members to avoid bulging or sagging of the veneered surfaces. With this consideration to be kept in mind, the struts or bridging sections 8 may be inclined at any desired angle, depending 45 upon the stresses to be imposed thereon when the panel is put in use.

The core member I is secured to the frame by positioning the ends 6 of the core member in the grooves 5 and fastening them in place. There- 50 upon glue or cement is applied to the surfaces of the frame and to the surface engaging portions I and face sheets 4-4 applied thereto to complete the panel.

In a preferred form of construction the core as member is made up of a plurality of ribbon-like strips 99 of sheet material placed in edge to edge relation, each strip being made with surface engaging portions I designed to alternately engage and secure opposed surfaces of the fs-ee sheets, the surface engaging portions III of each strip 9 being interconnected by angularly disposed struts H to form a truss or bridging. In panels embodying this form of core member, each of two oppositely positioned frame members are grooved along the inner edges of both surfaces thereof, as at l2--I2, to receive "the respective end' portions l3- -l3 of adjacent core strips 9. Thus the end portions of adjacent strips are secured to opposite sides of-the frame members, the strips being so positioned with respect to the frame that adjacent aligned surface engaging portions I 0. thereof engage opposed surfaces of the face veneers. '4

The combination of assembled stiles, rails and core members herein described comprise compound frames, so designed that the particular angles created by the struts or bridging sections 8 of the 'core member cannot alter without change in the length or width, as the case may be, of

claim as new and desire to protect by Letters Patent is:

A reinforced, warp wood panel and the like, comprising a rectangular frame, face sheets glued on opposite faces of said frame, a reinforcing core member within said panel in the form of an angular, corrugated thin sheet of wood veneer, the corrugations therein presenting flat gluing faces to the inner surfaces of said face sheets and flat bridging portions interconnecting said gluing faces and zig-za ing between said face sheets to form a bridge truss, said core veneer terminating in gluing faces secured in grooves in opposite sides of said frame.
